Fill the mold 21. The tractor 23 is configured to abut the chain 3 of the chain abutment area 213, and the chain 3 is pulled to move around the chain abutment zone 201249633 213, and the gap filler has been opened. The chain red L, #, > 蜾 蜾 3 3 卜 and will be sent along the chain abutment area 213 to the glue filling port. In the present embodiment, the glue filling device 2 includes a hold... for example, a coffee The portion holding the back of the chain 3 and the chain device 2 includes a roller 2 " for the chain 3 to abut; and is disposed around the glue mold 21 to rotate the chain 3 to be filled by the roller The glue part is sent to the glue filling port 216 for the private glue private order ' or the chain tooth 3 which is separated from the completed gap filler is matched with the chain 3 of various sizes and specifications, and the glue filling device 2 is set with an adjustable wheel 24,, > main κ 丨 丨 and he will refer to Figure 10 in May, as shown in Figure 4 for the adjustable position of the roller for the filling mold On the outside of the glue filling port 216 of the filling mold 21, the portion of the chain 3 to be filled is abutted against the smashing of the roller a glue filling port 216, the adjustable position roller 24' is screwed on the support rod 24'3, and the support rods 24, 3 are pivotally disposed on the rubber filling device 2 through the pivots 24, 1 and are on the side Attached to the elastomer 24'2 that is coupled to the filler 2, the adjustable position roller 24 is rotatable about the pivot 24'1 by the struts 24, 3 to allow the adjustable position roller 24, can be adapted to the chain 3 of various sizes, and relatively close or close to the 5 keling port 216. The elastic body 24'2 is, for example, a coil spring to provide the strut 24'3 with an elastic pushing force toward the rubber filling mold 21, and the adjustable position roller 24 can be kept close to the chain 3. The glue filling port 216 of the filling mold 21. 201249633 Please refer to FIGS. 6-8, which are schematic views of a filling mold in a rubber filling device according to another embodiment of the present invention, wherein FIG. 7 is a side view of the rubber filling device of FIG. It is a cross-sectional view taken along line BB of the gluing device of Fig. 7. It should be noted that in order to facilitate the description, the features and advantages of the present embodiment will be understood, and only the differences from the structures and functions of the foregoing embodiments will be described below, and the same or similar components are The same or approximate symbolic representation. As shown in the figure, in the intermediate portion of the chain abutting portion 213 of the present embodiment, a convex portion 2131 is formed to push the backing of the chain 3 to shield the lining of the sprocket 31 when the rear side of the chain 3 abuts. The sprocket 31 is exposed on the back side of the chain 3, and the sputum helps the filling port 216 to fill the gap between the sprocket 31 via the back surface of the chain 3. In the embodiment, the convex portion 2131 is a convex ring that surrounds the chain abutting portion 213, and the filling port 216 is disposed on the convex portion 2131. In addition, the contour of the chain abutment region 213 is gradually reduced by the convex portion 2131 toward the opposite ends, so that the linings constituting the two ends of the chain 3 abut against the chain abutment region 213 at different angles. The sprocket 31 is exposed on the back side of the chain 3, and the waterproof rubber is filled into the gap of the sprocket 31 via the exposed portion of the sprocket 31, thereby enhancing the effect of the waterproof rubber filling the gap of the sprocket 31. . The present invention is used to fill the gap between the chain elements of the chain to make the disclosure of the present invention clear. The steps of the filling method are as follows: First, a peripheral portion is provided with an arc. The filling mold is provided with a glue-filling space and a glue-filling port and a glue-filling port which are connected to the plastic-filling space. The glue-filling port is disposed on the side of the filling mold. Next, the back side of the chain is abutted against the side of the glue mold, and the fastener elements of the chain are aligned with the glue fill. Finally, the pressurized waterproof glue is sent into the adhesive space through the glue port, and flows out through the glue filling port to fill the gap between the fastener elements. In summary, the present invention provides a gluing device, a mold and a method thereof for filling a gap between the chain elements of the chain, the gluing device comprising a gluing mold, a heater and a tractor. The glue filling mold is a cylindrical body with a curved outer peripheral portion, which can be abutted against the back side of the chain, and has a glue filling opening at the abutting portion of the chain to flow out the waterproof glue, and the waterproof glue passes through the chain. The back surface is filled with a gap between the aforementioned fastener elements. The heater is used to melt the waterproof glue in the filling mold. The tractor is adapted to pull the chain to move about the chain abutment zone. The glue filling device can form an arc-shaped contour by the filling mold, so that the elastic chain belt can be pressed against the glue filling opening, and the waterproof glue is effectively filled into the gap between the chain teeth of the chain, thereby lifting the chain. Waterproof. The embodiments described above are intended to illustrate the principles of the invention and its advantages, and are not intended to limit the invention.
