Description
Technical Field
[0001] The utility model relates to the technical field of zipper processing, in particular to a suturing processing device for invisible zipper chain elements and a webbing. Background Art
[0002] Invisible zippers are a type of zipper, consisting of chain teeth, ribbons, locking parts, etc. Invisible zippers generally have two pieces of ribbons, each with a row of chain teeth. The two rows of chain teeth are staggered with each other, and the two rows of chain teeth can be separated and fixed by the locking parts. During the production process of invisible zippers, the chain teeth and ribbons need to be sewn together.
[0003] Application number: CN202322331743.4 "A sewing processing device for invisible zipper chain teeth and ribbon" First, the chain teeth are wound on the first winding drum, and the ribbon is wound on the second winding drum, with the chain teeth on the top and the ribbon on the bottom. The chain teeth and the ribbon pass through the first squeezing roller and the first rotating roller together. The first rotating roller provides rotational power through the motor on one side, driving the chain teeth and the ribbon to pass slowly. The first spring has a downward elastic force on the sliding plate, and the sliding plate drives the first squeezing roller to squeeze the chain teeth and the ribbon, so that the chain teeth and the ribbon overlap together. The chain teeth and the ribbon pass upward through the limit plate, and the limit plate aligns the chain teeth and the ribbon and guides them between the second rotating roller and the second squeezing roller, through the second The motor on one side of the rotating roller provides rotational power to it, and the second rotating roller drives the chain teeth and webbing to move to the right at the upper part of the shell. The second rotating roller rotates slightly faster than the first rotating roller, which can keep the chain teeth and webbing in a taut state. The second spring provides an upward elastic force to the sliding box, so that the second squeezing roller squeezes the chain teeth and webbing, thereby tightly clamping the chain teeth and webbing. Chain teeth and webbings of different thicknesses can also be used. The chain teeth and webbing pass between the two positioning plates at a uniform speed to the right, and the sewing mechanism sews the chain teeth and webbing. By fixing the chain teeth above the webbing and adjusting the chain teeth and webbing through the limit plate and positioning plate, the effect of preventing the chain teeth and webbing from being entangled is achieved.
[0004] However, in the above-mentioned sewing processing device, the chain teeth and ribbons may not be straightened when they are between the two positioning plates, thereby affecting the sewing quality. In addition, the distance between the two positioning plates cannot be adjusted, and it is impossible to limit the chain teeth and ribbons of different widths. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] See also Figure 1-5 The utility model provides a technical solution: a sewing processing device for invisible zipper chain elements and ribbons, comprising: a sewing mechanism 2, a workbench 4 is provided on the upper part of the sewing mechanism 2, two groups of limiting components 1 are provided on the upper part of the workbench 4, and a winding component 5 and a traction component 3 are respectively provided on both sides of the sewing mechanism 2.
[0026] The limit assembly 1 includes a fixed plate 13, the bottom of which is fixedly connected to the top of the workbench 4, and the two ends of the fixed plate 13 are slidably connected to the outside of the guide rod 12. One end of the guide rod 12 is fixedly connected to one side of the limit plate 11, and the other end of the guide rod 12 is fixedly connected to one side of the limit block 15. A spring 14 is provided between the limit block 15 and the fixed plate 13, and the spring 14 is connected to the outside of the guide rod 12. The middle portion of the fixed plate 13 is threadedly connected to the outside of the push rod 17, one end of the push rod 17 is fixedly connected to one side of the knob 16, and the other end of the push rod 17 is movably connected to one side of the limit plate 11.
[0027] Furthermore, the two sets of limiting plates 11 limit the chain teeth and the webbing to prevent the chain teeth and the webbing from being misaligned during sewing. When the distance between the two sets of limiting plates 11 needs to be adjusted according to the chain teeth and webbing of different widths, it is only necessary to turn the knob 16. When the knob 16 drives the push rod 17 to rotate clockwise, the push rod 17 moves toward the direction of the limiting plate 11, thereby causing the end of the push rod 17 to push the limiting plate 11, so that the limiting plate 11 is away from the fixed plate 13, thereby achieving the two sets of limiting plates 11 to move closer to each other, thereby reducing the distance between the two sets of limiting plates 11; on the contrary, if When the knob 16 drives the push rod 17 to rotate counterclockwise, the push rod 17 moves away from the limit plate 11. At the same time, the spring 14 pushes the limit block 15 away from the fixed plate 13, and the limit block 15 drives the limit plate 11 to move toward the fixed plate 13 through the guide rod 12, thereby realizing that the two groups of limit plates 11 move away from each other, thereby increasing the distance between the two groups of limit plates 11; through the above method, the distance between the two groups of limit plates 11 can be adjusted, so that the two groups of limit plates 11 can limit chain teeth and ribbons of different widths, thereby improving the applicability of the sewing processing device.
[0028] The winding assembly 5 includes: a chain tooth winding roller 51 and a ribbon winding roller 52. The two ends of the chain tooth winding roller 51 and the ribbon winding roller 52 are rotatably inserted into the side of the support plate 53. The bottom of the support plate 53 is fixedly connected to the outside of the sewing mechanism 2. The side of the support plate 53 is provided with a speed reducer 54.
[0029] Furthermore, the chain teeth are wound on the chain tooth winding roller 51, and the ribbon is wound on the ribbon winding roller 52, with the chain teeth on the top and the ribbon on the bottom, to ensure continuous feeding of the chain teeth and the ribbon.
[0030] The speed reducer 54 comprises a sleeve 542, one side of which is fixedly connected to one side of the support plate 53. The inner ring of the sleeve 542 slides over the sides of two sets of friction blocks 541. A spring 2 543 is provided between the two sets of friction blocks 541. The ends of the two sets of friction blocks 541 slide over the ends of the shafts of the chain element winding roller 51 and the webbing winding roller 52, respectively.
[0031] Furthermore, spring 2 543 pushes the friction block 541, so that the two groups of friction blocks 541 form friction with the axial ends of the chain tooth winding roller 51 and the ribbon winding roller 52 respectively, thereby increasing the rotational resistance of the chain tooth winding roller 51 and the ribbon winding roller 52. In this way, under the pulling of the traction component 3, the chain teeth and the ribbon will be straightened, and the sewing parts of the chain teeth and the ribbon will be in a straightened state, so as to ensure the sewing quality of the chain teeth and the ribbon.
[0032] The traction assembly 3 includes a support block 37. The bottom of the support block 37 is fixedly connected to the outside of the sewing mechanism 2. The side of the support block 37 is fixedly connected to the outside of the motor 36. The output shaft of the motor 36 is fixedly connected to the end of the driving roller 38. The top of the support block 37 is fixedly connected to the bottom end of the vertical rod 35. The top of the vertical rod 35 is fixedly connected to the bottom of the second limit block 32. The side of the vertical rod 35 is slidably inserted into the inside of the slider 34. The side of the slider 34 is rotatably connected to the two ends of the pressure roller 31. A spring 33 is installed between the second limit block 32 and the slider 34. The inner ring of the spring 33 is sleeved on the outside of the vertical rod 35.
[0033] Furthermore, the chain teeth and the webbing pass through the two sets of limit plates 11 together, and then pass through the pressure roller 31 and the active roller 38. The spring three 33 pushes the slider 34 to move downward, and the slider 34 drives the pressure roller 31 to move downward, thereby causing the pressure roller 31 and the active roller 38 to clamp the chain teeth and the webbing to increase the friction. Then, the motor 36 drives the active roller 38 to rotate, thereby driving the chain teeth and the webbing to move from the winding component 5 toward the traction component 3.
[0034] Working principle: When in use, the chain teeth are wound around the chain tooth winding roller 51, and the webbing is wound around the webbing winding roller 52, with the chain teeth on top and the webbing on the bottom. The chain teeth and the webbing pass through the two sets of limit plates 11 together, and then pass through between the pressure roller 31 and the active roller 38. The spring 33 pushes the slider 34 to move downward, and the slider 34 drives the pressure roller 31 to move downward, thereby causing the pressure roller 31 and the active roller 38 to clamp the chain teeth and the webbing to increase friction. Then, the motor 36 drives the active roller 38 to rotate. The spring 2 543 pushes the friction block 541, so that the two groups of friction blocks 541 form friction with the shaft ends of the chain tooth winding roller 51 and the ribbon winding roller 52 respectively, thereby increasing the rotational resistance of the chain tooth winding roller 51 and the ribbon winding roller 52. In this way, under the pulling of the traction component 3, the chain teeth and the ribbon will be straightened, and the sewing parts of the chain teeth and the ribbon will be in a straightened state to ensure the sewing quality of the chain teeth and the ribbon.
[0035] The two sets of limiting plates 11 limit the chain teeth and the webbing to prevent the chain teeth and the webbing from being displaced during sewing. When the distance between the two sets of limiting plates 11 needs to be adjusted according to the chain teeth and webbing of different widths, it is only necessary to turn the knob 16. When the knob 16 drives the push rod 17 to rotate clockwise, the push rod 17 moves toward the direction of the limiting plate 11, thereby causing the end of the push rod 17 to push the limiting plate 11, so that the limiting plate 11 is away from the fixed plate 13, thereby achieving the two sets of limiting plates 11 to move closer to each other, thereby reducing the distance between the two sets of limiting plates 11; on the contrary, if the knob 16 is turned clockwise, the push rod 17 will move clockwise. When 16 drives the push rod 17 to rotate counterclockwise, the push rod 17 moves away from the limit plate 11. At the same time, the spring 14 pushes the limit block 15 away from the fixed plate 13, and the limit block 15 drives the limit plate 11 to move toward the fixed plate 13 through the guide rod 12, thereby realizing that the two groups of limit plates 11 move away from each other, thereby increasing the distance between the two groups of limit plates 11; through the above method, the distance between the two groups of limit plates 11 can be adjusted, so that the two groups of limit plates 11 can limit chain teeth and ribbons of different widths, thereby improving the applicability of the sewing processing device.
