Description

Technical Field

[0001] This utility model belongs to the field of zipper tape technology, specifically a zipper tape weaving and forming device. Background Technology

[0002] Zipper tape is a flexible strip-shaped fabric woven from cotton yarn, chemical fiber, or blended materials. Its main function is to support the zipper teeth, slider, limiters, and other components of the zipper. Through the warp and weft textile structure, it provides sufficient strength and flexibility, allowing the zipper to open and close smoothly. It is widely used for connecting the opening parts of various products such as clothing, bags, and tents.

[0003] Zipper tape weaving and forming equipment typically involves a yarn warping process to arrange the disordered yarns in an orderly manner; then a weaving process is carried out, where polyester yarns and other materials are woven into a fabric tape on a weaving machine; next, nylon monofilaments are heated, toothed, and wound around the center line to form chain teeth through a forming machine; finally, the chain teeth and the woven fabric tape are sewn together by a sewing machine to form a zipper tape.

[0004] Traditional rigid clamping claws can easily cause surface indentations or breakage to soft or precision wires (such as nylon zipper tape and decorative threads). Furthermore, zipper production often requires switching between wires of different diameters or materials (from 0.1mm ultrafine fibers to 2mm metal wires), and traditional mechanical structures require frequent clamp replacements. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a zipper tape weaving and forming device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The zipper tape weaving and forming device of this utility model includes a clamping assembly. The clamping assembly includes two fixing plates. A shape memory alloy clamping block is fixedly connected to the opposite side of the two fixing plates. A heating element is fixedly connected to the side of the shape memory alloy clamping block facing the fixing plate. The sides of the two heating elements that are far apart from each other are fixedly connected to the fixing plates. A T-shaped sliding block is fixedly connected below the fixing plates and the shape memory alloy clamping blocks.

[0007] Preferably, the inner walls of the two T-shaped sliding blocks are threadedly connected to a transmission mechanism, which includes a motor. The output end of the motor is fixedly connected to a bidirectional threaded rod, and the outer wall of the bidirectional threaded rod is threadedly connected to the inner walls of the two T-shaped sliding blocks.

[0008] Preferably, a support assembly is fixedly connected to the right side of the motor. The support assembly includes a support column, and a square fixing block is fixedly connected above the support column. A T-shaped sliding groove is formed above the square fixing block.

[0009] Preferably, the inner wall of the T-shaped sliding groove is slidably connected to the outer wall of the T-shaped sliding block, the inner wall of the square fixing block is rotatably connected to the outer wall of the bidirectional threaded rod, and the left side of the square fixing block is fixedly connected to the right side of the motor.

[0010] Preferably, a No. 1 workbench is fixedly connected below the support column, the No. 1 workbench includes a No. 2 workbench, and support legs are fixedly connected to the four corners below the No. 2 workbench. The top of the No. 2 workbench is fixedly connected to the bottom of the support column.

[0011] Preferably, a No. 1 roller is fixedly connected to the rear side above the No. 2 workbench. The No. 1 roller includes two support plates, and the No. 2 roller is rotatably connected to the opposite surfaces of the two support plates.

[0012] Preferably, the two support plates are fixedly connected to the top of the second workbench.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The zipper tape weaving and forming device described in this utility model addresses the issue that traditional rigid clamping devices, when clamping wires, are prone to causing indentations, deformation, or even breakage to soft or fragile wires due to excessive clamping force or uneven force, thus affecting the quality of the zipper tape. The clamping component can automatically adjust the clamping force according to the thickness of the wire. The shape memory alloy clamping block has the characteristics of shrinking when heated and recovering when cooled, flexibly wrapping the wire, avoiding local stress concentration, and effectively reducing damage to the wire.

[0015] 2. The zipper tape weaving and forming device described in this utility model is used when producing different types of zipper tapes. Various specifications and materials of wire are required. Traditional clamping devices can only be adapted to wires of specific specifications. When changing wires, manual adjustment or replacement of clamps is required, which is cumbersome and inefficient. The clamping components do not require complex mechanical adjustments and can adapt to wires of different thicknesses, hardness and materials, which greatly improves the versatility and production efficiency of the equipment.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 4 As shown in the embodiment of this utility model, a zipper tape weaving and forming device includes a clamping assembly 1. The clamping assembly 1 includes two fixing plates 11. A shape memory alloy clamping block 12 is fixedly connected to the opposite face of each of the two fixing plates 11. A heating element 13 is fixedly connected to the side of the shape memory alloy clamping block 12 facing the fixing plate 11. The sides of the two heating elements 13 that are far apart from each other are fixedly connected to the fixing plates 11. T-shaped sliding blocks 14 are fixedly connected below the fixing plates 11 and the shape memory alloy clamping blocks 12. A transmission mechanism 2 is threadedly connected to the inner wall of the two T-shaped sliding blocks 14. The transmission mechanism 2 includes a motor 21. A bidirectional threaded rod 22 is fixedly connected to the output end of motor 21. The outer wall of the bidirectional threaded rod 22 is threadedly connected to the inner wall of two T-shaped sliding blocks 14. A support assembly 3 is fixedly connected to the right side of motor 21. The support assembly 3 includes a support column 31. A square fixing block 32 is fixedly connected above the support column 31. A T-shaped sliding groove 33 is opened above the square fixing block 32. A first workbench 4 is fixedly connected below the support column 31. The first workbench 4 includes a second workbench 41. Support legs 42 are fixedly connected to the four corners below the second workbench 41. The upper part of the second workbench 41 is fixedly connected to the lower part of the support column 31.

[0025] The clamping assembly 1 solves the problems of surface indentation or breakage of soft or precision wires and the need for frequent clamp replacements in traditional mechanical structures. During use, the output of the motor 21 drives the bidirectional threaded rod 22 to rotate, causing the bidirectional threaded rod 22 and two T-shaped sliding blocks 14 to rotate threadedly. The two T-shaped sliding blocks 14 move towards the center and slide against the inner wall of the T-shaped sliding groove 33, allowing the two shape memory alloy clamping blocks 12 to clamp the wire. Then, the heating element 13 heats the shape memory alloy clamping blocks 12, causing the shape memory alloy... The shape memory alloy clamping block 12 contracts to clamp the wire. When it cools, the shape memory alloy clamping block 12 returns to its original shape and releases the wire. Traditional rigid clamping devices are prone to causing indentations, deformation, or even breakage of soft or fragile wires due to excessive clamping force or uneven force when clamping the wire, which affects the quality of the zipper tape. The clamping component 1 can automatically adjust the clamping force according to the thickness of the wire. The shape memory alloy clamping block 12 has the characteristics of shrinking when heated and restoring when cooled, which flexibly wraps the wire, avoids local stress concentration, and effectively reduces damage to the wire.

[0026] When producing different types of zipper tape, various specifications and materials of wire are required. Traditional clamping devices can only be used with wires of specific specifications. When changing wires, manual adjustment or replacement of clamps is required, which is cumbersome and inefficient. Clamping component 1 can adapt to wires of different thicknesses, hardness and materials without complicated mechanical adjustments, which greatly improves the versatility and production efficiency of the equipment.

[0027] like Figure 5 As shown, a No. 1 workbench is fixedly connected below the support column. The No. 1 workbench includes a No. 2 workbench. Support legs are fixedly connected to the four corners of the No. 2 workbench. The top of the No. 2 workbench is fixedly connected to the bottom of the support column. A No. 1 line roller is fixedly connected to the rear side of the top of the No. 2 workbench. The No. 1 line roller includes two support plates. The No. 2 line roller is rotatably connected to the opposite surfaces of the two support plates. The bottom of the two support plates is fixedly connected to the top of the No. 2 workbench.

[0028] Working principle: The clamping assembly 1 solves the problems of surface indentation or breakage of soft or precision wires and the need for frequent clamp replacements in traditional mechanical structures. During use, the output of the motor 21 drives the bidirectional threaded rod 22 to rotate, causing the bidirectional threaded rod 22 and two T-shaped sliding blocks 14 to rotate threadedly. The two T-shaped sliding blocks 14 move towards the center and slide against the inner wall of the T-shaped sliding groove 33, allowing the two shape memory alloy clamping blocks 12 to clamp the wire. Then, the heating element 13 heats the shape memory alloy clamping blocks 12, causing the shape memory alloy to... The shape memory alloy clamping block 12 contracts to clamp the wire, and when cooled, it returns to its original shape and releases the wire. Traditional rigid clamping devices are prone to causing indentations, deformation, or even breakage of soft or fragile wires due to excessive clamping force or uneven force, which affects the quality of the zipper tape. The clamping component 1 can automatically adjust the clamping force according to the thickness of the wire. The shape memory alloy clamping block 12 has the characteristics of shrinking when heated and restoring when cooled, which flexibly wraps the wire, avoids local stress concentration, and effectively reduces damage to the wire.

[0029] When producing different types of zipper tape, various specifications and materials of wire are required. Traditional clamping devices can only be used with wires of specific specifications. When changing wires, manual adjustment or replacement of clamps is required, which is cumbersome and inefficient. Clamping component 1 can adapt to wires of different thicknesses, hardness and materials without complicated mechanical adjustments, which greatly improves the versatility and production efficiency of the equipment.
