Detailed Implementation
[0023] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.
[0024] Example:
[0025] See Figure 1 - Figure 7 This embodiment relates to a zipper tooth 10 clamping device, which is specifically used for the precise control of clamping, positioning, installation spacing, and fixing angle of metal zipper teeth 10 on an automated production line, thereby ensuring the accuracy of zipper installation and product consistency. The device includes a frame 11, a platform 12 is provided above the frame 11, and a movable pressure plate 13 and a fixed pressure plate 14 are rotatably mounted on the platform 12. The movable pressure plate 13 and the fixed pressure plate 14 are circumferentially arranged with several sets of pressure grooves 15, and both the movable pressure plate 13 and the fixed pressure plate 14 are axially connected to a drive motor 16 for driving their rotation. A pressing module 17 for driving the movable pressure plate to press down is provided above the platform 12.
[0026] Specifically, in this embodiment, the frame 11 serves as an overall support structure, with a platform 12 fixedly mounted on top. A movable pressure plate 13 and a fixed pressure plate 14 are rotatably mounted on the platform 12, each connected to a drive motor 16 via its respective shaft, enabling synchronous reverse rotation. When the chain belt 01 is conveyed to the device, its teeth are initially fixed but not yet clamped. In use, the chain belt 01 to be clamped is placed between the movable pressure plate 13 and the fixed pressure plate 14. The movable pressure plate 13 is driven downwards by the pressing module 17, causing the chain teeth 10 to embed into the pressure grooves 15 on both sides (movable pressure plate 13 and fixed pressure plate 14), achieving clamping and fixation with the chain belt 01 under pressure. A raised structure 18 is provided between adjacent pressure grooves 15 on the movable pressure plate 13 and the fixed pressure plate 14. The width of the raised structure 18 corresponds to the spacing between the chain teeth, so that the raised structure 18 separates adjacent chain teeth during the rotation of the movable pressure plate 13 and the fixed pressure plate 14, and then clamps the chain teeth through the pressure grooves 15 on the upper and lower sides. This utility model, by setting the movable pressure plate 13 and the fixed pressure plate 14 and evenly distributing the pressure grooves 15, can accurately clamp the zipper teeth 10 in conjunction with the lower pressure module 17, ensuring that the positional spacing of the chain teeth 10 remains consistent during the clamping process, and significantly improving the processing accuracy of fixing the chain teeth 10. In this embodiment, the chain belt 01 also needs to be moved by an external traction device (such as a winding machine) to realize the sequential clamping of each group of chain teeth on the chain belt 01, realizing the continuous clamping operation of the chain belt 01, which is suitable for automated assembly line operation and improves the overall production efficiency.
[0027] In this embodiment, see Figure 7 The pressure groove 15 has guide edges 21 on both sides. The guide edges 21 have a trapezoidal cross section and are provided with guide slopes 22. The guide slopes 22 of the two sets of limiting baffles are arranged facing each other. The distance between the two sets of limiting baffles is adapted to the length of the chain teeth 10. When the traction force of the chain belt 01 is insufficient and the chain belt 01 becomes slack, the movable pressure plate 13 and the fixed pressure plate 14 rotate. Under the action of the guide slopes 22 on both sides, the chain teeth 10 can be guided more accurately into the groove. In this embodiment, the groove is adapted to the shape of the chain teeth 10.
[0028] The pressing module 17 includes a gantry 23 fixedly mounted on a platform 12 and a drive cylinder 24. The gantry 23 has two sets of movable bearings 25 slidably mounted vertically. A rotating shaft 26 is rotatably connected to each set of movable bearings 25. One end of the rotating shaft 26 is shaft-connected to a drive motor 16, and the bearing on the side away from the drive motor 16 is fixedly connected to the piston rod of the drive cylinder 24. The cylinder body of the drive cylinder 24 is fixedly mounted on the platform 12, and a guide hole is provided on the bearing near the drive motor 16. A guide rod 27, which slides and adapts to the guide hole, is vertically fixed between the gantry 23 and the platform 12. Driven by the cylinder, both sets of movable bearings 25 can move vertically along the guide rod 27, thereby driving the movable pressure plate 13 to perform a pressing action, ensuring that the chain teeth 10 receive sufficient and uniform clamping force during installation. Specifically, the movable pressure plate 13 rises when the piston rod extends and presses down when the piston rod retracts.
[0029] See Figure 3 The platform 12 is provided with a guide groove 31, and a plurality of rollers 32 are rotatably arranged in the guide groove 31. The chain belt 01 moves along the guide groove 31 under traction. The rollers 32 can reduce the frictional resistance of the chain belt 01 during the conveying process. In addition, rollers 32 are not required in the meshing (chain teeth clamping) area between the movable pressure plate 13 and the fixed pressure plate 14.
[0030] See Figure 5 In this embodiment, a bending plate 33 is provided on one side of the guide groove 31, and a limiting strip 34 is provided below the bending plate 33. An adjusting bolt 35 for driving the limiting strip 34 to move is provided on the bending plate 33. One end of the adjusting bolt 35 is rotatably connected to the limiting strip 34 and is also screwed into a threaded hole on the bending plate 33. The distance between the limiting strip 34 and one side of the bending plate 33 is adjusted by turning the adjusting screw to meet the processing requirements of chain belts 01 of different widths.
[0031] After clamping, the chain teeth may exhibit quality defects such as wear and misalignment. To avoid batches of defective products, the chain belt 01 after clamping needs to be inspected periodically. In this embodiment, a shearing component 41 is provided at one end of the platform 12. The shearing component 41 can cut the chain belt 01 into small segments for sampling, which are used for quality inspection. The shearing component 41 is a shearing machine, which includes a shearing seat 42, a fixed blade 43, a movable blade 44, and a drive handle 45. The shearing seat 42 is fixedly mounted on the platform 12, and the fixed blade 43 is connected and fixed to the shearing seat 42. One end of the movable blade 44 and the drive handle 45 are both hinged to the shearing seat 42, and the other end of the movable blade 44 is hinged to the drive handle 45 through a shearing arm 46. By manually turning the drive handle 45, the drive shearing arm 46 drives the movable blade 44 to swing downward toward the fixed blade 43, and the chain belt 01 is cut under the combined action of the movable blade 44 and the fixed blade 43.
[0032] A partition 51 is fixedly installed on the frame 11, located below the platform 12. Two sets of fixed bearing seats 52 are connected and fixed on the partition 51, and the fixed pressure plate 14 is rotatably connected to the two sets of fixed bearing seats 52 via a rotating shaft 26. Side plates 53 are provided on the front and rear sides of the frame 11. Stiffening plates 54 are fixedly installed below the connection points between the platform 12 and the partition 51 and the side plates 53. In this embodiment, the stiffening plates 54 can improve the support strength of the platform 12 and the partition 51, making the operation of the movable pressure plate 13 and the fixed pressure plate 14 more stable.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
