Referring to Figures 1 and 2, an embodiment of the present invention provides a dry electrode preparation device for preparing powder into a roll film. The dry electrode preparation device includes a vibration blanking device and a roll film forming device (not shown), the vibration blanking device is used to use vibration to drop the powder onto the roll film forming device, and the roll film forming device is used to heat and roll the powder, so that the powder is pressed into a roll film under high temperature and high pressure.

The vibrating blanking device includes a hopper mechanism 10 and a vibrating mechanism 20. The hopper mechanism 10 has a The vibrating mechanism 20 includes two vibrating assemblies 21, each vibrating assembly 21 includes a base 211, a spring piece 212, a vibrating inclined plate 213 and a vibration source 214. The vibrating inclined plate 213 is connected to the base 211 through the spring piece 212, so that the vibrating inclined plate 213 can vibrate freely relative to the base 211. The vibration source 214 is arranged on the vibrating inclined plate 213 to provide vibration to the vibrating inclined plate 213, so that the vibrating inclined plate 213 vibrates relative to the base 211. The vibrating inclined plates 213 of the two vibrating assemblies 21 are spaced apart from each other and are located below the above-mentioned discharge port 11. A feed port 210 is formed between the tops of the vibrating inclined plates 213 of the two vibrating assemblies 21, and a blanking slit 215 is formed between the bottoms of the two vibrating inclined plates 213. The powder material outputted from the discharge port 11 falls from the feed port 210 onto the two vibrating inclined plates 213, and under the vibration of the vibrating inclined plates 213, the powder material falls from the material dropping slit 215 onto the roller film forming device below. Optionally, the spring sheet 212 can be a spring sheet. The vibration source 214 can be a pneumatic vibration source or an electric vibration source.

In the above-mentioned vibration blanking device, during the process of vibration blanking, the powder contained in the hopper mechanism 10 is output downward through the discharge port 11, and enters between the two vibration inclined plates 213 through the feed port 210 between the tops of the two vibration inclined plates 213, and then falls onto the two vibration inclined plates 213. The vibration source 214 transmits the vibration to the vibration inclined plates 213, so that the vibration inclined plates 213 vibrate, and then under the action of the vibration, the powder on the vibration inclined plates 213 continuously falls from the blanking slit 215. The powder falling from the blanking slit 215 enters the roller film forming device, and the roller film forming device rolls the powder into a roller film.

Thus, in the vibration blanking device of the present invention, the vibration inclined plate 213 is connected to the base 211 through the spring piece 212. Since the spring piece 212 can produce elastic deformation, the vibration inclined plate 213 is subjected to less damping during the vibration process, so that the vibration inclined plate 213 can smoothly and flexibly vibrate relative to the base 211, so that the vibration inclined plate 213 vibrates more evenly and the vibration frequency can meet the blanking requirements, thereby ensuring uniform blanking. Specifically in the embodiment, the width dimension of the discharge port 11 is smaller than the width dimension of the feed port 210, so that the powder material output downward from the discharge port 11 can all enter between the two vibration inclined plates 213 through the feed port 210.

Specifically in the embodiment, the two vibrating inclined plates 213 gradually move closer to each other from top to bottom (i.e., from top to bottom), so that the two vibrating inclined plates 213 are tilted, ensuring that the powder can fall onto the two vibrating inclined plates 213, and then gradually fall from the falling slit 215 between the bottoms of the two vibrating inclined plates 213 under the action of vibration.

Specifically in the embodiment, the discharge port 11, the feed port 210 and the blanking slit 215 are all arranged along the same Strips extending longitudinally in a preset direction. Each vibration component 21 includes a plurality of spring pieces 212, which are connected between the base 211 and the vibration inclined plate 213 and are arranged at intervals along the preset direction. In this way, the vibration inclined plate 213 is connected to the base 211 using a plurality of spring pieces 212. On the one hand, the connection of the vibration inclined plate 213 is made more reliable, and on the other hand, the vibration inclined plate 213 can vibrate more smoothly and flexibly relative to the base 211, further ensuring uniform material dropping. Specifically in the embodiment shown in FIG. 2 , each vibration inclined plate 213 is connected to the base 211 via four spring pieces 212.

Optionally, one end of each spring sheet 212 is fixedly connected to a spring sheet seat 2123, and the spring sheet seat 2123 is fixedly connected to the base 211. The other end of each spring sheet 212 is pressed and fixed to the vibration inclined plate 213 through a spring sheet pressing plate 2125.

Specifically in the embodiment, the vibration inclined plate 213 includes an upper inclined plate 2131 and a lower inclined plate 2133. The top of the upper inclined plate 2131 is connected to the base 211 through the spring sheet 212, and the vibration source 214 is arranged on the upper inclined plate 2131. The lower inclined plate 2133 is connected to the bottom of the upper inclined plate 2131, and the above-mentioned blanking slit 215 is formed between the lower inclined plates 2133 of the two vibration inclined plates 213. Among them, the rigidity of the lower inclined plate 2133 is less than the rigidity of the upper inclined plate 2131, that is, the rigidity of the upper inclined plate 2131 is larger, and the rigidity of the lower inclined plate 2133 is smaller. In this way, due to the larger rigidity of the upper inclined plate 2131, the vibrations of various positions of the upper inclined plate 2131 are relatively consistent when the vibration source 214 drives the upper inclined plate 2131 to vibrate. Since the rigidity of the lower inclined plate 2133 is relatively small, it is beneficial to increase the amplitude of the lower inclined plate 2133 and avoid the amplitude reduction when the vibration is transmitted to the position of the lower inclined plate 2133, which is further beneficial to improve the vibration uniformity of the vibrating inclined plate 213 and ensure uniform material dropping.

It is understandable that the rigidity of the lower inclined plate 2133 can be made smaller than the rigidity of the upper inclined plate 2131 by changing the material and/or thickness.

In the embodiment of the present invention, the two vibration inclined plates 213 are arranged at intervals from each other along the first horizontal direction X (i.e., the width direction of the blanking slit 215). The vibration blanking device also includes a base 30, on which each of the bases 211 is arranged, and the base 211 is adjustable relative to the base 30 along the first horizontal direction X and/or the vertical direction Z. Specifically in the embodiment shown in FIG. 1 , the first horizontal direction X is the left-right direction, and the preset direction is the direction perpendicular to the paper surface.

In this way, the positions of the two vibrating inclined plates 213 in the first horizontal direction X can be adjusted by adjusting the positions of the bases 211 relative to the base 30 along the first horizontal direction X, that is, the width of the blanking slit 215 between the two vibrating inclined plates 213 can be adjusted. The position of each base 211 relative to the base 30 is adjusted, thereby adjusting the position of the two vibrating inclined plates 213 in the vertical direction Z, that is, achieving the purpose of adjusting the distance between the two vibrating inclined plates 213 and the roller-pressing film-forming device below.

Specifically in the embodiment, each vibration component 21 also includes an adapter 216 and a crossbeam 217, wherein the adapter 216 is disposed on the base 30, the crossbeam 217 is fixedly connected to the adapter 216, and the base 211 is disposed on the crossbeam 217. The adapter 216 is adjustable relative to the base 30 along the vertical direction Z, and the base 211 is adjustable relative to the crossbeam 217 along the first horizontal direction X (i.e., the width direction of the blanking slit 215). In this way, when it is necessary to adjust the distance between the two vibration inclined plates 213 and the roller film forming device below them, it can be achieved by adjusting the position of the adapter 216 relative to the base 30 along the vertical direction Z. When it is necessary to adjust the width of the blanking slit 215, it can be achieved by adjusting the position of the base 211 relative to the crossbeam 217 along the first horizontal direction X.

Of course, in another embodiment, the adapter 216 may be adjustable relative to the base 30 along the first horizontal direction X, and the base 211 may be adjustable relative to the cross beam 217 along the vertical direction Z, as long as the width of the blanking slit 215 can be adjusted, and the spacing between the two vibrating inclined plates 213 and the roller film forming device thereunder can be adjusted, and no limitation is made here. For ease of understanding, the following description is based on the example that the adapter 216 is adjustable relative to the base 30 along the vertical direction Z, and the base 211 is adjustable relative to the cross beam 217 along the first horizontal direction X.

Specifically in the embodiment, the base 30 includes two bottom plates 31, and each vibration assembly 21 includes two adapters 216. The two bottom plates 31 are relatively fixed and arranged at intervals along the second horizontal direction Y (i.e., the length direction of the blanking slit 215). The two adapters 216 of each vibration assembly 21 are respectively arranged on the two bottom plates 31, and the crossbeam 217 of each vibration assembly 21 is fixedly connected between the two adapters 216. In this way, the assembly structure of the vibration assembly 21 is more stable and reliable.

Specifically in the embodiment, each adapter 216 is provided with a first waist-shaped hole 2161 extending longitudinally along the vertical direction Z, and each adapter 216 is locked on the corresponding bottom plate 31 by a first locking member 218 penetrating through the first waist-shaped hole 2161. Each base 211 is provided with a second waist-shaped hole (not shown) extending longitudinally along the first horizontal direction X (i.e., the width direction of the blanking slit 215), and each base 211 is locked on the corresponding crossbeam 217 by a second locking member (not shown) penetrating through the second waist-shaped hole. In this way, when it is necessary to adjust the distance between the two vibrating inclined plates 213 and the roller-pressed film-forming device below them, the first locking member 218 on each adapter 216 is loosened, so that each adapter 216 It is adjustable relative to the bottom plate 31 along the vertical direction Z, thereby driving the two vibration inclined plates 213 to move respectively along the vertical direction Z. When the two vibration inclined plates 213 are adjusted in place along the vertical direction Z, tighten each first locking member 218 so that each adapter 216 is locked and fixed on the bottom plate 31. When it is necessary to adjust the width of the blanking slit 215, loosen the second locking member on each base 211 so that each base 211 is adjustable relative to the cross beam 217 in the first horizontal direction X, thereby driving the two vibration inclined plates 213 to move respectively along the first horizontal direction X, thereby achieving the purpose of adjusting the width of the blanking slit 215 between the bottoms of the two vibration inclined plates 213. When the width of the blanking slit 215 between the bottoms of the two vibration inclined plates 213 is adjusted in place, tighten each second locking member so that each base 211 is locked and fixed on the cross beam 217. Optionally, the first locking member 218 and the second locking member can be a locking screw.

Furthermore, each vibration assembly 21 also includes two threaded adjustment members 219 corresponding to the two adapters 216, and each adapter 216 is provided with a first threaded hole (not shown), the central axis of the first threaded hole being parallel to the vertical direction Z. Each threaded adjustment member 219 is rotatably connected to the base plate 31 and is threadedly connected to the corresponding adapter 216, so that the adapter 216 can be driven to move along the vertical direction Z relative to the base plate 31 by screwing the threaded adjustment member 219. In this way, when it is necessary to adjust the distance between the two vibration inclined plates 213 and the roller film forming device below them, first loosen the first locking member 218 on each adapter 216, and then drive each adapter 216 to move along the vertical direction Z relative to the base plate 31 by screwing each threaded adjustment member 219, thereby driving the two vibration inclined plates 213 to move along the vertical direction Z respectively. When the two vibration inclined plates 213 are adjusted to the correct position along the vertical direction Z, the screwing of each threaded adjusting member 219 is stopped, and each first locking member 218 is tightened, so that each adapter seat 216 is locked and fixed on the bottom plate 31 .

Specifically in the embodiment, the vibration blanking device further includes two side plates 40, and the base 30 further includes a mounting rod 32 fixedly connected between the two bottom plates 31. The two side plates 40 are both mounted on the mounting rod 32 and are located at both ends of the two vibration inclined plates 213 in the second horizontal direction Y (i.e., the length direction of the blanking slit 215), so that the two vibration inclined plates 213 and the two side plates 40 are enclosed together to form a receiving cavity, so that the two side plates 40 play a role in preventing the powder from leaking out from both ends of the two vibration inclined plates 213 in the second horizontal direction Y. Specifically, the first horizontal direction X intersects with the second horizontal direction Y, and preferably, the first horizontal direction X is perpendicular to the second horizontal direction Y.

Furthermore, there is a preset gap between each side plate 40 and the two vibration inclined plates 213. Thus, on the one hand, the side plate 40 can prevent the powder from leaking out, and on the other hand, the side plate 40 can be prevented from interfering with the vibration movement of the two vibration inclined plates 213. It should be noted that the preset gap can be set according to specific circumstances and is not limited here.

Furthermore, the positions of the two side plates 40 along the mounting rod 32 are adjustable (i.e., adjustable along the second horizontal direction Y), so as to adjust the preset gap between the side plates 40 and the two vibration inclined plates 213. In this way, when it is necessary to adjust the position of the side plates 40 along the mounting rod 32, first release the locking between the side plates 40 and the mounting rod 32, so that the side plates 40 can move along the mounting rod 32. When the position of the side plates 40 along the mounting rod 32 is adjusted to the right position, the side plates 40 are locked and fixed on the mounting rod 32. It is understandable that the locking and fixing between the side plates 40 and the mounting rod 32 can be achieved by a more common structure such as a clamping structure or a locking screw, which is not limited here.

Specifically in the embodiment, the base 30 includes two mounting rods 32 arranged at intervals along the first horizontal direction X (i.e., the width direction of the blanking slit 215), and the two mounting rods 32 are fixedly connected between the two bottom plates 31. The hopper mechanism 10 includes two guide slots 12 arranged at intervals along the first horizontal direction X. The bottoms of the two guide slots 12 are respectively mounted on the two mounting rods 32, and the above-mentioned discharge port 11 is formed between the bottoms of the two guide slots 12. The two guide slots 12 are used to guide the powder loaded onto the guide slots 12 to the discharge port 11, so that the powder continuously falls from the discharge port 11. In this way, the powder is loaded onto the two guide slots 12, and under the guiding effect of the two guide slots 12, the powder continuously flows to the discharge port 11 and is discharged downward from the discharge port 11.

Optionally, each guide slot plate 12 includes a support plate 121 and a baffle plate 123, and baffle plates 123 are installed at both ends of the support plate 121 in the second horizontal direction Y (i.e., the length direction of the blanking slit 215), so that the support plate 121 and the two baffle plates 123 thereon jointly enclose a guide slot (not shown in the figure), which is used to receive the powder and guide the powder to the bottom of the support plate 121. The above-mentioned discharge port 11 is formed between the bottoms of the support plates 121 of the two guide slot plates 12, so that the powder moves along the guide slot toward the discharge port 11 until it is discharged from the discharge port 11.

Furthermore, the two support plates 121 gradually move closer together from top to bottom (ie, from top to bottom), so that the two support plates 121 are tilted, ensuring that the powder can move along the two support plates 121 toward the discharge port 11 .

The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. As long as there is no contradiction in the combination of these technical features, they should all be considered to be within the scope of this specification.

The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
