[0028] Example

[0029] Please see Figure 1-5 This utility model provides a technical solution: a zipper tooth pressing device for zipper production, including a pressing table 1 for zipper production, a switch (not shown in the figure) installed on one side of the pressing table 1, support rods 8 fixed on both sides of the top of the pressing table 1, a limit rod 9 fixed on the top of the support rod 8, and a cylinder 4 fixed on the top of the limit rod 9; a pressure plate 6 located below the limit rod 9 is fixed to the push rod end of the cylinder 4, and a pressing tooth 7 for pressing the zipper tooth is fixed to the bottom of the pressure plate 6. The push rod end of the cylinder 4 extends out and pushes the pressure plate 6 and the pressing tooth 7 to move downward. When the pressing tooth 7 contacts the zipper tooth, the zipper tooth is pressed into the zipper fabric under the thrust of the cylinder 4. This solution only improves the direction of the protective component 5, and the rest is the same as the authorized solution. Since it is not an improvement point, it is not described in detail.

[0030] A pressing component 2 is provided on one side of the top of the pressing table 1, and a protective component 5 is provided on the outside of the pressing teeth 7;

[0031] The protective component 5 includes a geared motor 53, with a lead screw 54 fixed to the output shaft end of the geared motor 53. A first connecting rod 52 is threadedly connected to the outside of the lead screw 54. A transparent protective cover 51, sleeved on the outside of the support rod 8, is fixed to the outside of the first connecting rod 52. The output shaft of the geared motor 53 is controlled to rotate clockwise, which drives the lead screw 54 to rotate. The lead screw 54 is threadedly connected to the first connecting rod 52, causing the transparent protective cover 51 and the second connecting rod 57 to move downward along the slide rod 55. A through hole 56 is provided on one side of the transparent protective cover 51. For conveying the chain fabric, a sliding rod 55 is fixed between the pressing table 1 and the limiting rod 9. A second connecting rod 57, which is fixed to the inner wall of the transparent protective cover 51, is slidably connected to the outside of the sliding rod 55. The bottom of the reduction motor 53 is fixed to the top side of the limiting rod 9. The outside of the lead screw 54 is rotatably connected to the pressing table 1 and the limiting rod 9 respectively. The transparent protective cover 51 can effectively block the outside of the pressing plate 6 and the pressing teeth 7 during the pressing process, preventing external objects from accidentally entering the pressing area, thereby avoiding crushing or pinching accidents that may be caused by misoperation or equipment failure.

[0032] The pressing assembly 2 includes two pressure rollers 21. An insertion groove 22 is provided between the outer side of the pressure roller 21 and the top of the pressing table 1. The two sides of the pressure roller 21 are rotatably connected to the connecting frame 24 through bearings. Rotating the turntable 25 clockwise drives the screw 26 to rotate, thereby causing the pressure roller 21 to descend and fit against the chain cloth. The operation is relatively simple and intuitive. The threaded connection between the screw 26 and the connecting frame 24 ensures the stability of the movement of the pressure roller 21. A sliding column 23 fixed to the top of the pressing table 1 is movably inserted through one side of the connecting frame 24. A limit block 27 is fixed at the top of the sliding column 23. The rotation amount of the turntable 25 is controlled to finely adjust the descent distance of the pressure roller 21, thereby realizing the control of the pressing of the chain cloth and chain teeth, reducing the difficulty of operation, and allowing the operator to adjust the position of the pressure roller 21 without complicated training. A screw 26 is rotatably connected to one side of the top of the pressing table 1. The turntable 25 is fixed at the top of the screw 26. The outer side of the screw 26 is threadedly connected to one side of the connecting frame 24. The pressure roller 21 is located on one side of the through hole 56.

[0033] Working principle: When it is necessary to press the zipper teeth, simply insert the zipper cloth into the insertion slot 22, and then rotate the turntable 25 clockwise. The turntable 25 drives the screw 26 to rotate. The screw 26 is threadedly connected to the connecting frame 24, so that the pressure roller 21 moves downward along the slide column 23. When the outer side of the pressure roller 21 is in contact with the outer side of the zipper cloth, stop rotating the turntable 25. In this way, the zipper cloth is clamped in sequence at the bottom of the two pressure rollers 21, and the zipper teeth are pre-clamped on one side of the zipper cloth. Then, control the push rod end of the cylinder 4 to extend and push the pressure plate 6 and the pressure tooth 7 to move downward. When the pressure tooth 7 contacts the zipper teeth, the zipper teeth and the zipper cloth are pressed together under the thrust of the cylinder 4.

[0034] During pressing, simply press the switch to control the output shaft of the reduction motor 53 to rotate clockwise. The output shaft of the reduction motor 53 drives the lead screw 54 to rotate. The lead screw 54 is threadedly connected to the first connecting rod 52, causing the transparent protective cover 51 and the second connecting rod 57 to move downward along the slide rod 55. At this time, the transparent protective cover 51 covers the outside of the pressure plate 6 and the pressure teeth 7, preventing external objects from entering the underside of the pressure plate 6 and the pressure teeth 7 and causing accidental injury. When it is necessary to place the chain teeth, simply press the switch to control the output shaft of the reduction motor 53 to rotate counterclockwise, causing the transparent protective cover 51 to move upward, exposing the gap between the pressure plate 6 and the pressure teeth 7 and the pressing table 1. At this time, the chain teeth can be placed.

[0035] Then pull the chain cloth, and under the tension of the chain cloth, the pressure roller 21 will rotate, pre-clamping the chain teeth again, and completing the pressing of the chain teeth and chain cloth for the next part.

[0036] In summary, the clockwise rotation of the turntable 25 drives the screw 26 to rotate, thereby causing the pressure roller 21 to descend and adhere to the chain fabric. The operation is relatively simple and intuitive. The threaded connection between the screw 26 and the connecting frame 24 ensures the stability of the pressure roller 21's movement. The operator can fine-tune the descent distance of the pressure roller 21 by controlling the rotation of the turntable 25, thereby controlling the pressing of the chain fabric and chain teeth. This reduces the difficulty of operation, allowing operators to adjust the position of the pressure roller 21 without complicated training. The device can adapt to chain fabrics and chain teeth of different specifications and materials, enhancing the equipment's versatility.

[0037] By controlling the rotation direction of the output shaft of the geared motor 53, the transparent protective cover 51 can be easily moved up and down. The transparent protective cover 51 can effectively block the outside of the pressure plate 6 and the pressure teeth 7 during the pressing process, preventing external objects from accidentally entering the pressing area, thereby avoiding crushing or pinching accidents that may be caused by misoperation or equipment failure, and greatly improving the safety of operation. The transparent protective cover 51 is made of transparent material, so it can protect the safety of operators while ensuring that they can clearly observe the situation during the pressing process.
