Description

The utility model relates to a leveling device, in particular to a leveling device for stone slabs.

If the thickness of the slab is uneven or arc-shaped, it needs to be leveled. Otherwise, direct grinding will easily cause the slab to break or cause the failure of the automatic grinding machine; building materials or furniture that require high processing precision must also be leveled. Usually, leveling is to grind the slab with a horizontal diamond grinding head many times, but because the diamond teeth of the diamond grinding head have a large contact surface with the slate, it is easy to cause the slab to break or lose corners. When leveling marble slabs, when the leveling depth exceeds 3mm, the leveling speed will slow down due to many processing procedures, especially when leveling hard granite slabs, the speed will be slower when the leveling depth exceeds 1.5mm. Also slow down and take longer.

Among the known leveling technologies for stone slabs, there is one that uses four sets of horizontal diamond grinding heads for grinding. When leveling a marble slab, each set of diamond grinding heads grinds to remove a thickness of 0.5 mm, and the four sets grind a total of 2 mm. When the removal amount exceeds 3mm, after the first leveling, the stone slab needs to be retracted for another leveling. If the leveling is a granite slab, because the material is particularly hard, each set of diamond grinding heads can only grind If 0.2mm is removed, the four groups will remove 0.8mm in total. When the leveling depth exceeds 1.5mm, it needs to be leveled twice or even three times, so the grinding speed is very slow.

Another stone slab leveling technology is to use rollers, such as continuous grinding with 8 rollers. The outer circle of the rollers is welded with diamond teeth in a spiral shape, and the rollers rotate at high speed. The diamond teeth on the outer circle grind the stone slab. Similar to head grinding, that is, the grinding contact surface is large, the resistance of the stone plate is large, and the leveling speed is slow. If the grinding speed is increased or the grinding depth is increased, the leveling of the stone plate will be slower, otherwise the stone plate will be cracked or missing corners.

The purpose of this utility model is to design a stone slab cutting and leveling machine for the shortcomings of slow slab leveling speed, long time consumption, insufficient leveling depth, and difficult leveling of thin slabs. The surface of the stone slab is cut with a number of equal-depth grooves according to the preset depth. After continuous cutting on each axis, all the protruding parts of the stone slab are cut and cleared into flat plates. Slate, can quickly level the slate.

The stone slab cutting and leveling machine of the utility model can be an independent stone slab leveling equipment alone, and can also be combined with an automatic grinding machine in series to form an automatic grinding unit.

The stone slab cutting and leveling machine of the utility model includes a machine body, several horizontal shafts, a driving device for the horizontal shaft consisting of a motor fixed on the machine body, an upper and lower pulley, a belt, and left and right bearing seats pivotally arranged at both ends of the horizontal shaft. , and a plurality of diamond circular saws fitted on the main shaft with the card sleeve, is characterized in that: it also includes a plurality of spacer plates which are assembled on the horizontal axis by the card sleeve and are used to equally divide and separate each diamond circular saw; the diamond The circular saws have the same outer diameter, and the outer diameter of the spacer is slightly smaller than the outer diameter of the diamond circular saw blade.

After the stone slab is input by the conveyor belt, the surface is cut into a set of grooves of equal depth by a plurality of diamond circular saw blades with the first horizontal axis structure according to a predetermined depth, and then a set of diamond circular saw blades with the second horizontal axis structure The slices continue to cut to increase the depth of the groove, or a set of diamond circular saw blades with the second horizontal axis structure cuts the slender parts on both sides of the groove on the surface of the stone slab, or directly grinds with the horizontal diamond grinding head of the subsequent automatic grinding machine , to achieve the purpose of leveling the slate.

Referring to Fig. 1, when the multi-axis stone slab cutting and leveling machine of the present invention has only a single axis, it can be clearly seen from the cutaway part of the middle part in the figure that the multi-slice diamond circular saw 10 and its equal division and partition diamond The spacer plates 31-40 of the circular saw are fitted on the horizontal shaft 20 by clamping. The left and right bearing seats 21 and 22 are respectively pivoted at the two ends of the horizontal shaft 20. A belt pulley 23 is pivoted at the outer end of the bearing seat 21. On the body 1 A motor 24 is fixed, and driven by an upper pulley 25 and a belt 26, the lower pulley 23 is driven to rotate to make the horizontal shaft 20 rotate.

A reinforced bearing seat 27 is pivotally arranged at the left end of the lower belt pulley 23 to make the power transmission more stable. The right end of the horizontal axis 20 is pivotally equipped with a movable dovetail-shaped right bearing seat 22, above which there is a dovetail structure, which can be connected with the body 1, fixed and removed from the body, for replacing or adjusting each diamond circular saw 10 and each partition plate 31-40 position.

The leftmost flange spacer plate 31 is locked on the transverse shaft 20 with several screws, then runs through each diamond circular saw 10 and spacer plates 31, 32, ... 40 with two long screws 28, and finally locks with nuts 29. The rightmost flange spacer 40 and the spacer in the middle are provided with a keyway 12 connected with a key 13 to strengthen the combination with the horizontal shaft 20, and the rightmost flange spacer 40 is locked with a large nut 14 The horizontal shaft 20 is to ensure that all the circular saw blades 10 are combined with all the spacer plates 31-40 and the horizontal shaft 20 to act together. As shown in FIG. 2 , it is a schematic diagram of the movement of the stone plate to the second axis, and the stone plate moves along the tangential direction of the rotation.

On the machine tool 3 below the circular saw 10, the slate 2 is imported by the conveyor belt 4, and a guide plate 5 is respectively arranged on both sides on the conveyor belt 4 to make the slate 2 advance smoothly. The conveyor belt is driven by a motor 76 through a gearbox 77, please refer to Fig. 4 and Fig. 5 at the same time. The front end of the machine tool 3 is pivotally equipped with a pressurized front roller 6 to prevent the slate 2 from loosening, floating or retreating, and to ensure that the slate advances at the same speed as the conveyor belt. The forward direction of the slate is identical and parallel to the direction of rotation of the multi-disc diamond circular saw 10 .

When the horizontal shaft 20 rotates, since each circular saw 10 and each spacer plate 31-40 are closely combined with the horizontal shaft, the sharp diamond teeth of the diamond circular saw 10 cut the surface of the slate 2 to produce multiple grooves of equal depth. In the embodiment with two horizontal axes, the pressurized middle roller 7, the pressurized rear roller 71, and the final roller 78 are also pivotally installed in and behind the two sets of circular saw groups, and a pressurized spring 75 is added to the main shaft of each roller. , The effect of the middle and rear rollers is the same as that of the pressurized front rollers 6, see Fig. 5.

The cutting and leveling machine of the utility model is similar in structure to the multi-piece diamond circular saw cutting machine. It is easy to cut stone slabs. Diamond cutting is used instead of diamond grinding, which can greatly increase the cutting line speed. Usually, the line speed of the grinding head is 8-10 m/ seconds, the current cutting marble can reach 45-50 m/s, and the cutting granite is 28-32 m/s. The leveling speed and depth can be increased several times, and the leveling is smooth, stable and rapid, and the processing technology is improved.

The outer diameter of the partition plate that divides and partitions the diamond circular saw is relatively large. After deducting the height of the diamond teeth on both sides for the diamond circular saw, it is reduced by about 3mm, that is, the outer diameter of the partition plate is similar to that of the diamond circular saw. After the outer diameter of the partition plate is enlarged, the diamond circular saw is locked and cannot be deflected, and the cutting rate increases. For example, cutting marble can increase from 300-600 square centimeters per minute to more than 3,000 square centimeters per minute; cutting granite From 30-60 square centimeters per minute per piece to 300 square centimeters per piece per minute, the cutting rate has increased by more than five times and the cutting capacity has been improved.

The utility model is also characterized in that it can cut repeatedly and continuously in a multi-axis type to increase the leveling depth. After a group of diamond circular saws on the first axis cut out a group of grooves with a depth of 4mm, if a group of diamond circular saws on the second axis cuts out a group of grooves with a depth of 4mm, The setting of the diamond circular saw is the same as that of the first group of diamond circular saws, that is, the grooves at the same position can be cut, and the grooves with a depth of 8mm can be easily cut. Subsequent cuts in the third and fourth axes can be deeper. Generally, the two-axis cutting and leveling machine can meet various process requirements.

Unless it is mass production, generally only single-axis cutting and single-axis horizontal diamond grinding are used. Its superior cutting ability can deepen the cutting depth at one time, such as 3-6mm, and produce multiple grooves. The stone slabs on both sides of the convex grooves appear as independent slender strips, with a thickness within 3mm. Taking advantage of the hard and fragile characteristics of stone, The diamond teeth of the subsequent horizontal diamond grinding head continuously collide with each independent and protruding slender strip of stone during high-speed operation to crush and separate the remaining fine protruding particles from the bottom surface of the diamond teeth. flat.

In Fig. 3, a machine base 50 is arranged between the first shaft structure 8 and the second shaft structure 9, and the machine base 50 has the first shaft structure 8 and the second shaft structure 9 at the same time, and there is a lifting screw 51, 52 on both sides of the machine base 50 To drive the first and second shaft structures 8, 9 to move up and down, the upper ends of the screw rods 51, 52 protrude outside the machine base 50, and the lower ends are fixed at the lower ends of the L-shaped plates 53, 54 in the machine base 50, relative to the two-axis structure 8, 9, the middle positions of the opposite sides are connected with a female nut sleeve 55, 56, so that the screw rod 51 penetrates into the female nut sleeve 55, so that the upper and lower heights of the first shaft structure 8 can be adjusted by the adjustment button on the upper end of the screw rod 51 . Similarly, the screw rod 52 is threaded into the female nut sleeve 56, and the adjustment knob at the upper end of the screw rod 52 can also be used to adjust the vertical height of the second shaft structure. The position of the two-axis structure relative to the machine base 50 can be adjusted in either manual or electric air-oil pressure mode. Therefore, the multi-piece diamond circular saw 10 on the first axis structure 8 cuts the slate 2 at equal intervals and equal depths. After the groove is formed, the conveyor belt 4 is transported along the direction of the guide plate 5 to the diamond circular saw 10 of the second shaft structure 9 for cutting. After sawing the follow-up cutting, all the protruding parts on the surface of the slate are cut and removed. One side of the L-shaped plate 53 in the support 50 is connected with a pressurized middle roller 7, so that there is pressure between the two shafts to apply to the slate.

Replace the flange spacers at the leftmost and rightmost ends of the second axis, align all the diamond circular saws with the protruding parts of the stone slab, adjust the lifting screw of the machine base, and fix the lifting nut sleeve at the position of the machine body, the body of the second axis and The machine base uses a female nut sleeve and a screw for the body to move up and down. Setting the height of the body of each axis structure is the setting of the height of the diamond circular saw. Due to the high cutting line speed and cutting rate of the diamond circular saw, the cutting ability is very strong, and the stone slab can be easily and quickly leveled, and there is no problem of cracking or missing corners during grinding.

After being cut by two sets of diamond circular saws on the first and second axes, there may be cutting marks on the surface; after the saw blade has been used for a long time, the outer circle of the diamond teeth will be slightly worn into a fine arc, which will also be scratched on the surface of the stone slab. The remaining fine protruding lines, whose height is usually within 0.3mm, as shown in Fig. 4 and Fig. 5, can be ground by two subsequent horizontal diamond grinding heads 72, 73 to achieve leveling.

As shown in Figure 5, the flat plate cut by the second axis is input into the follow-up horizontal diamond grinding head 72, 73 for grinding by the pressure roller 71. Generally, the effect of two-axis grinding is better, which is the prior art of the present utility model. The diamond grinding head is disc-shaped, with diamond teeth welded on the outer circle of the bottom surface, usually with a size of 20×10×12mm, an interval of 15mm, a linear speed of about 8-10m/s, and a fixed-point horizontal rotation. The electric motor 74 controls the lifting and adjustment Height, the main shaft is pivoted on the disc, and the belt pulley is pivoted on the upper end of the main shaft, which is driven by an upright motor on the horizontal grinding head frame at the rear end. The height of the bottom surface of the diamond tooth is controlled by the lifting motor, and its height is set to be 0.2mm lower than the surface of the stone slab after cutting by the second axis, and it will be leveled after the second grinding.

After setting, the slate is output to the leveling machine through the pressurized roller, and is continuously ground by the aforementioned follow-up automatic grinder, or automatically sucked onto the pallet by the vacuum suction cup.

The forward speed of the stone slab is driven and controlled by the drum wheels at both ends of the machine tool. The drum wheel at the rear end of the machine tool is driven by a coaxial gearbox. The conveying speed of the conveyor belt is usually controlled at 0.5-3 m/min. Hardness and other adjustments. For example, the marble slab is about 1.5-3 meters per minute, and the granite slab is about 0.5-2 meters per minute.

If the leveling is arc-shaped slate, the traditional leveling machine is difficult to level and even cause the slab to break. Using the cutting and leveling machine of the utility model, the concave surface of the slate is input into the leveling machine downwards, and the cutting and leveling is performed first. Flatten its curved surface, and then repeatedly level its concave surface, it can be easily and quickly leveled.

Usually, it is very difficult to level thin slabs. Not only is the speed slow, but it is easy to break the slabs. For example, granite slabs have a width of 400-600mm and a thickness of 10-13mm to 4-6mm. If the traditional machine is used for leveling, almost All of them are broken, but the stone slabs with a thickness of 6-50mm and a width of 150-600mm can be easily and quickly leveled with this cutting and leveling machine.

Before the leveling operation, in addition to routinely checking the power supply, cooling water source, diamond sawing board, lubrication system, and slate texture, it is also necessary to adjust the cutting height of the diamond circular saw, the grinding height of the horizontal diamond grinding head and the width of the guide plate.
