Description

Technical Field

[0001] The present invention relates to the technical field of zipper dyeing equipment, in particular to a dyeing equipment for zipper production. Background Art

[0002] A zipper is a connector that connects or separates items by relying on continuously arranged chain teeth. Existing zippers are usually connected to long strips of fabric to form zipper fabric.

[0003] At present, in order to facilitate the dyeing of zipper cloth, the zipper cloth is usually immersed in a dyeing barrel. Two synchronously rotating rollers are arranged in the dyeing barrel, and the zipper cloth is sequentially wound around the two rotating rollers. When the two rotating rollers rotate synchronously, all surfaces of the zipper cloth will be in direct contact with the dye, achieving an immersion dyeing effect.

[0004] However, due to the relatively fine fiber density of the zipper fabric, the dye cannot penetrate into the inner layer of the fabric in a short period of time, resulting in a color difference between the inner and outer layers of the fabric. Therefore, in the existing technology, it is necessary to extend the dyeing time to reduce the degree of color difference, but long-term dyeing will result in low dyeing efficiency, and the color difference between the inner and outer layers will still exist. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a dyeing device for zipper production to solve the technical problems of the existing immersion dyeing method of zipper cloth in the background technology, which has low efficiency and easily forms color difference between the inner and outer layers of the cloth, resulting in poor dyeing effect.

[0010] Furthermore, the second driving roller includes a roller body and a sleeve seat sleeved on the roller body and rotating synchronously with the roller body, and the second threaded portion is provided on the sleeve seat; Among them, the driving module also includes a bidirectional screw that is transmission-connected to the second driving roller, and a part of the sleeve seat is screwed to the bidirectional screw, so that through the rotation of the bidirectional screw, the sleeve seat drives the second rotating roller to perform lifting and reciprocating motion relative to the first rotating roller.

[0011] Furthermore, the fiber spreading module further comprises a sealing box and a support frame, wherein the sealing box and the support frame are respectively used to carry the two groups of squeezing rollers; Part of the transmission bracket is disposed in the sealed box, and the other part is connected to the support frame after at least one turn, and the transmission bracket is used to drive the support frame to reciprocate toward the sealed box.

[0014] Furthermore, the second driving roller assembly further includes a moving plate, a cam and an elastic member, the elastic member is sleeved on the transmission bracket, and two ends of the elastic member are respectively connected to the sealing box and the transmission bracket; The movable plate is connected to the end of the transmission bracket and is arranged outside the dyeing barrel. The cam is sleeved on the bidirectional screw and faces the movable plate.

[0015] Furthermore, the dyeing equipment further includes an infusion tube for extending into the dyeing barrel, and the infusion tube is used to input dyeing liquid into the dyeing barrel.

[0016] Compared with the prior art: In a dyeing device for zipper production proposed in the present invention, a fiber spreading module and a driving module are arranged in the dyeing barrel of the present application, so that when the rotating roller group drives the zipper cloth to be wound and transmitted, two groups of squeezing rollers in the fiber spreading module are relatively arranged on opposite sides of the zipper cloth, and at least one group of the squeezing rollers is connected to the driving module through the transmission bracket to drive the transmission bracket and one group of the squeezing rollers to intermittently reciprocate toward the other group of the squeezing rollers, so as to form a transmission channel with a size greater than / less than / equal to the zipper cloth between the two groups of the squeezing rollers. When the size of the transmission channel is smaller than the zipper cloth, the zipper cloth is bent and transmitted in the two groups of the squeezing rollers to The fibers in the zipper cloth are pulled and unfolded, that is, during the winding and transmission process of the zipper cloth, the size of the transmission channel between the two sets of squeezing rollers is intermittently changed, so that the zipper cloth can be transformed from straight transmission to curved transmission, and then from curved transmission to straight transmission.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] See also Figures 1-9 , shown is a zipper production dyeing device in one embodiment of the present invention, comprising a dyeing barrel 100, a rotating roller assembly 200, a fiber spreading module 400 and a driving module 500. The rotating roller assembly 200 is used to drive the zipper fabric 300 to be wound and transported in the dyeing barrel 100; The fiber spreading module 400 is disposed in the dyeing barrel 100 and is used to face the transmission path of the zipper fabric 300. The fiber spreading module 400 includes a transmission bracket 410 and at least two sets of squeezing rollers 420. Two sets of squeezing rollers 420 are arranged on opposite sides of the zipper fabric 300, and at least one set of squeezing rollers 420 is connected to a driving module 500 via a transmission bracket 410. The driving module 500 is used to drive the transmission bracket 410 and one set of squeezing rollers 420 to intermittently reciprocate toward the other set of squeezing rollers 420, thereby forming a transmission channel between the two sets of squeezing rollers 420 with a size greater than / less than / equal to the size of the zipper fabric 300. Each set of squeezing rollers 420 includes a plurality of squeezing rollers 420 , and each squeezing roller 420 in one set of squeezing rollers 420 is staggered with each squeezing roller 420 in another set of squeezing rollers 420 . This allows the zipper fabric 300 to be bent and transported between the two sets of squeezing rollers 420 to pull and unfold the fibers in the zipper fabric 300 when the size of the transmission channel is smaller than the zipper fabric 300 .

[0024] In a specific implementation, the zipper fabric 300 can be driven to be wound and transported in the dyeing barrel 100 by rotating the roller group 200. During the transport process, two groups of squeezing rollers 420 are relatively arranged on opposite sides of the zipper fabric 300 in the fiber unfolding module 400, and at least one group of squeezing rollers 420 is connected to the driving module 500 through the transmission bracket 410, so as to drive the transmission bracket 410 and one group of squeezing rollers 420 to intermittently reciprocate toward the other group of squeezing rollers 420, so as to form a transmission channel with a size greater than / less than / equal to the zipper fabric 300 between the two groups of squeezing rollers 420. When the size of the transmission channel is smaller than the zipper fabric 300, the zipper fabric 300 is bent and transported in the two groups of squeezing rollers 420, so as to stretch the fibers in the zipper fabric 300. Pulling and unfolding, that is, during the winding and transmission process of the zipper fabric 300, the size of the transmission channel between the two sets of squeezing rollers 420 is intermittently changed, so that the zipper fabric 300 can be transformed from straight transmission to curved transmission, and then from curved transmission to straight transmission. In the process of curved transmission, the fibers of the fabric in the zipper fabric 300 can be unfolded, so that the fibers on the surface of the fabric and the fibers in the inner layer of the fabric can directly contact the dyeing liquid, thereby effectively dyeing the zipper fabric 300 in a short time, and at the same time, it can also avoid the color difference between the inner and outer layers of the fabric, achieving high dyeing efficiency and short dyeing time. At the same time, during the process of changing the zipper fabric 300 from curved transmission to straight transmission, the fibers of the fabric can be prevented from being excessively pulled, thereby achieving lossless unfolding.

[0025] Please refer to the following for details: Figure 9 As shown, Figure 9 The zipper fabric 300 in the left figure is transported in a straight manner, and the zipper fabric 300 in the right figure is transported in a curved manner.

[0026] To facilitate the transmission of the zipper cloth 300, please refer to Figure 2-Figure 8 As shown, in this embodiment, the driving module 500 includes a driving member 510, a first driving roller set 520 and a second driving roller set 530; The driving member 510, the first driving roller group 520 and the second driving roller group 530 are sequentially connected in a transmission manner, so that the driving member 510 drives the first driving roller group 520 and the second driving roller group 530 to rotate simultaneously; The first driving roller assembly 520 is used to assemble the rotating roller assembly 200 so that the rotating roller assembly 200 drives the zipper fabric 300 to be transported in the dyeing barrel 100; The second driving roller set 530 is used to drive the transmission bracket 410 to perform intermittent reciprocating motion.

[0027] Specifically, the first driving roller group 520 includes a first driving roller 522 having a first threaded portion 521 and a second driving roller 524 having a second threaded portion 523, wherein the rotating roller group 200 includes a first rotating roller 210 and a second rotating roller 220, the first rotating roller 210 is assembled on the first driving roller 522 through the first threaded portion 521, and the second rotating roller 220 is assembled on the second driving roller 524 through the second threaded portion 523.

[0028] It should be noted that, in this example, the driving member 510 can adopt a servo motor in the prior art, and a toothed chain structure can be used to synchronously transmit the transmission between the first driving roller 522 and the second driving roller 524. Specifically, gears can be provided on both the first driving roller 522 and the second driving roller 524, and the transmission between the gears is completed by a toothed chain. That is to say, the driving member 510 can drive the first driving roller 522 and the second driving roller 524 to rotate, and the first driving roller 522 and the second driving roller 524 can drive the first rotating roller 210 and the second rotating roller 220 to rotate synchronously. In specific implementation, the zipper cloth 300 is first wound around the first rotating roller 210, and then one end of the zipper cloth 300 is passed through the transmission channel and wound around the second rotating roller 220.

[0029] It should be noted that the spiral direction of the first threaded portion 521 and the second threaded portion 523 can be the same as the rotation direction of the first drive roller 522 and the second drive roller 524, so that the first drive roller 522 and the second drive roller 524 can rotate the first rotating roller 210 and the second rotating roller 220 more tightly during the rotation process.

[0030] In addition, in order to improve the dyeing effect of the zipper fabric 300, in some other preferred embodiments, the dyeing device further includes a liquid extraction module 600 having a transmission pipe 610; The transmission pipe 610 has two output ends connected to the first drive roller 522 and the second drive roller 524 respectively, and one input end connected to the dyeing barrel 100, for transmitting the dyeing liquid in the dyeing barrel 100 to the first drive roller 522 and the second drive roller 524 respectively; Among them, the first driving roller 522, the second driving roller 524, the first rotating roller 210 and the second rotating roller 220 all have a transmission cavity for connecting with the transmission pipe 610, and the first rotating roller 210 and the second rotating roller 220 are both provided with a through hole 620 for connecting with the corresponding transmission cavity.

[0031] It should be noted that the liquid extraction module 600 also includes a pump body for extracting liquid. For details, please refer to Figure 4 As shown, the input end of the pump body can extract the dyeing liquid in the dyeing barrel 100 into the transmission pipe 610, and the dyeing liquid is guided through the transmission pipe 610 so that the dyeing liquid can enter the transmission cavity of the first driving roller 522 and the second driving roller 524 respectively. In this embodiment, the first rotating roller 210 and the second rotating roller 220 are both hollow structures, so that the liquid can enter the first rotating roller 210 and the second rotating roller 220. Finally, combined with the through holes 620 on the first rotating roller 210 and the second rotating roller 220, the dyeing liquid can flow directly to the zipper cloth 300 on the first rotating roller 210 and the second rotating roller 220, thereby improving the dyeing effect.

[0032] In addition, to ensure uniformity of the zipper fabric 300 being wound around the second rotating roller 220, in this embodiment, the second driving roller 524 includes a roller body 5241, a sleeve seat 5242 sleeved on the roller body 5241 and rotating synchronously with the roller body 5241, and the second threaded portion 523 is provided on the sleeve seat 5242; Among them, the second drive roller group 530 includes a bidirectional screw 531 that is transmission-connected to the second drive roller 524, and a part of the socket 5242 is screwed to the bidirectional screw 531, so that through the rotation of the bidirectional screw 531, the socket 5242 is driven to drive the second rotating roller 220 to perform up and down reciprocating motion relative to the first rotating roller 210.

[0033] Specifically, the roller body 5241 on the second driving roller 524 can be connected to the first driving roller 522 and the bidirectional screw 531 through a toothed chain structure. That is, when the roller body 5241 rotates, the bidirectional screw 531 rotates synchronously. At this time, a part of the socket 5242 is screwed to the bidirectional screw 531, so that the socket 5242 can reciprocate along the bidirectional screw 531, thereby allowing the second rotating roller 220 to be raised and lowered, and can also rotate during the lifting process, so that the zipper cloth 300 can be evenly wound on the second rotating roller 220.

[0034] Please note that Figure 4 and Figure 7 As shown, the portion where the roller body 5241 and the second rotating roller 220 are sleeved is prismatic, and the sleeved area of ​​the second rotating roller 220 is correspondingly arranged to the prismatic portion of the roller body 5241. A prismatic sleeved hole may also be used.

[0035] In addition, in order to realize the intermittent reciprocating movement of a set of squeezing rollers 420, in this embodiment, refer to Figure 5 、 Figure 6 、 Figure 8 and Figure 9 As shown, the fiber spreading module 400 further includes a sealing box 430 and a support frame 440 , and the sealing box 430 and the support frame 440 are respectively used to carry two sets of squeezing rollers 420 ; Part of the transmission bracket 410 is disposed in the sealed box 430 , and the other part is connected to the support bracket 440 after at least one turn. The transmission bracket 410 is used to drive the support bracket 440 to reciprocate toward the sealed box 430 .

[0036] The fiber deployment module 400 further includes a support housing 450 and an adjustment member 460 , and the support frame 440 is slidably connected within the support housing 450 ; Among them, a part of the transmission bracket 410 passes through the support shell 450 and is connected to the support frame 440, the end of the adjustment member 460 is rotatably connected to the support shell 450, the middle part of the adjustment member 460 is screwed to the dyeing barrel 100, and the adjustment member 460 is used to adjust the gap between the support shell 450 and the sealing box body 430.

[0037] The fiber unfolding module 400 also includes a first limit member 470 and a second limit member 480 arranged on the support shell 450 and the sealing box body 430. The first limit member 470 and the second limit member 480 are arranged relative to each other so that when the support shell 450 moves toward the sealing box body 430, a limiting gap is formed between the first limit member 470 and the second limit member 480 to limit the moving direction of the zipper cloth 300.

[0038] The second driving roller assembly 530 further includes a moving plate 532, a cam 533, and an elastic member 534. The elastic member 534 is sleeved on the transmission bracket 410, and the two ends of the elastic member 534 are respectively connected to the sealing box 430 and the transmission bracket 410. The movable plate 532 is connected to the end of the transmission bracket 410 and is disposed outside the dyeing barrel 100 . The cam 533 is sleeved on the bidirectional screw 531 and faces the movable plate 532 .

[0039] For specific implementation, please refer to Figure 9As shown, the position of the support shell 450 can be moved by the adjusting member 460. The adjusting member 460 can specifically be a bolt, and the end of the adjusting member 460 can be rotatably connected to the support shell 450 by a bearing. By rotating the adjusting member 460, the gap between the support shell 450 and the sealing box 430 can be adjusted, so that the first limit member 470 and the second limit member 480 can be close to each other, thereby limiting the moving direction of the zipper cloth 300. It should be noted that the first limit member 470 and the second limit member 480 can both adopt a C-shaped structure. The first limit member 470 and the second limit member 480 can ensure that the zipper cloth 300 will not escape from the extrusion range of the two sets of extrusion rollers 420 during the winding process.

[0040] Please refer again Figure 5 As shown, after the adjustment is completed, due to the toothed chain structure used for transmission between the bidirectional screw 531 and the roller body 5241, the bidirectional screw 531 will drive the cam 533 to rotate during the rotation process. At this time, the movable plate 532 moves left and right along the contour of the cam 533. The movable plate 532 pulls the transmission bracket 410, so that the transmission bracket 410 can drive a group of squeezing rollers 420 on the support frame 440 to move closer to the squeezing rollers 420 on the sealing box 430, thereby forming a curved channel on the two groups of squeezing rollers 420, so that the zipper fabric 300 is transported in a curved manner, and the fibers of the fabric in the zipper fabric 300 can be pulled and unfolded. Finally, through the elastic member 534, the transmission bracket 410 can drive the group of squeezing rollers 420 on the support frame 440 to restore the straight channel, so that the zipper fabric 300 is transported in a straight manner.

[0041] In some other preferred embodiments, in order to facilitate the injection of dyeing liquid into the dyeing barrel 100, in this example, the dyeing equipment also includes an infusion tube 700 for extending into the dyeing barrel 100, and the infusion tube 700 is used to input the dyeing liquid into the dyeing barrel 100. Specifically, the infusion tube 700 is fixedly connected to the dyeing barrel 100.

[0042] In summary, the first embodiment of the present invention provides a dyeing device for zipper production, which arranges a fiber spreading module 400 and a driving module 500 in the dyeing barrel 100 of the present application, so that when the rotating roller group 200 drives the zipper cloth 300 for winding and transmission, two groups of squeezing rollers 420 in the fiber spreading module 400 are relatively arranged on opposite sides of the zipper cloth 300, and at least one group of squeezing rollers 420 is connected to the driving module 500 through the transmission bracket 410, so as to drive the transmission bracket 410 and one group of squeezing rollers 420 to intermittently reciprocate toward the other group of squeezing rollers 420, so as to form a transmission channel with a size greater than / less than / equal to the zipper cloth 300 between the two groups of squeezing rollers 420. When the size of the transmission channel is smaller than the zipper cloth 300, the zipper cloth 300 is bent in the two groups of squeezing rollers 420. The fibers in the zipper fabric 300 are stretched and unfolded. That is, during the winding and conveying process of the zipper fabric 300, the size of the transmission channel between the two sets of squeezing rollers 420 is intermittently changed, so that the zipper fabric 300 can be transformed from straight transmission to curved transmission and then from curved transmission to straight transmission. In the process of curved transmission, the fibers of the fabric in the zipper fabric 300 can be stretched, so that the fibers on the surface of the fabric and the fibers in the inner layer of the fabric can directly contact the dyeing liquid, thereby completing the effective dyeing of the zipper fabric 300 in a short time, and at the same time, avoiding the color difference between the inner and outer layers of the fabric, achieving the effects of high dyeing efficiency and short dyeing time. At the same time, during the process of the zipper fabric 300 being transformed from curved transmission to straight transmission, the fibers of the fabric can be prevented from being excessively stretched, thereby achieving lossless unfolding.
