Description

Technical Field

[0001] This utility model belongs to the technical field of zipper tape processing equipment, and relates to a feeding device for a zipper tape pre-expansion machine. Background Technology

[0002] The zipper belt is straight after manufacturing in the factory. A straight zipper can easily cause clothing to bunch up and the zipper to be difficult to open and close. The zipper needs to be pre-expanded to give the belt a certain inner curve. Existing technology uses zipper forming equipment to pre-expand and shape the zipper. The shaped zipper has an inner curve characteristic, and the inner curve is not easily deformed, improving the zipper quality and preventing it from buckling during use.

[0003] Chinese invention patent application CN119385384A discloses a zipper tape pre-expansion device, including a workbench, a feeding device and a pre-expansion device disposed on the workbench, and a discharging device disposed below the workbench. The discharging device is disposed below the workbench and includes a discharge cylinder disposed on one side of the workbench and connected to the pre-expansion device, a clamping mechanism, a receiving platform, and a packaging mechanism disposed on the other side of the workbench. The discharge cylinder has a discharge port disposed below the workbench. The clamping mechanism and the receiving platform are disposed between the discharge port and the packaging mechanism. The clamping mechanism is located below the workbench and is slidably disposed between the discharge port and the packaging mechanism. The receiving platform is disposed below the clamping mechanism and slides towards or away from the packaging mechanism. The receiving platform is also provided with a pusher plate that pushes the zipper tape packaged by the packaging mechanism away from the receiving platform. The clamping mechanism includes a rotary cylinder, a finger cylinder, and a clamping arm. The finger cylinder is mounted on the rotary cylinder and drives the opening / closing of the clamping arm. The rotary cylinder controls the rotation of the clamping arm. A first slide rail is provided below the worktable, and a slider is mounted thereon. One side of the slider is connected to the clamping mechanism, and the other side is connected to the first slide rail. The slider is connected to the rotary cylinder of the clamping mechanism. A second slide rail is provided below the receiving platform, and the receiving platform is mounted on the second slide rail. A third lifting mechanism is provided and connected to the receiving platform. When the receiving platform slides toward / away from the packaging mechanism, it drives the receiving platform to rise / fall.

[0004] The unloading device in this technical solution utilizes a rotary clamping mechanism that rotates counterclockwise during transport after clamping the zipper tape. This prevents the zipper tape from getting tangled on the clamping arms, ensuring it lands neatly on the receiving platform and facilitating packaging. However, the overall unloading device has a complex structure with numerous parts, resulting in high costs. Furthermore, during the process of releasing the zipper tape onto the receiving platform, the tape may shift due to external environmental factors, leading to uneven and misaligned placement, which affects subsequent packaging. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a feeding device for a neatly arranged zipper tape pre-expansion machine.

[0006] The objective of this utility model can be achieved through the following technical solution: A feeding device for a zipper belt pre-expansion machine includes a zipper belt, the zipper belt including a chain, an upper stop, a lower stop and a zipper lock. The upper stop and the lower stop are respectively located at both ends of the chain belt, and the sides of the upper stop and the lower stop both protrude from the chain belt. It also includes a discharge channel and two arc-shaped zipper guide rails. An arc-shaped downward inclined feeding slide is formed between the two zipper guide rails. The feeding slide includes a whole material slide. The width of the zipper lock is greater than the width of the whole material slide and the width of the chain. A limiting block is provided at the end of the whole material slide. The lower stop of the zipper belt extends out of the discharge channel and passes through the feeding slide. The zipper lock of the zipper belt extends out of the discharge channel. The zipper lock of the zipper belt contacts the top surface of the whole material slide, so that the zipper belt is suspended on the whole material slide and moves downward with the whole material slide until it contacts the limiting block.

[0007] In the feeding device of the zipper tape pre-expansion machine described above, the discharge channel is generally arc-shaped and wider at the front than at the back. One end of the discharge channel is the inlet, and the two sides of the other end of the discharge channel extend downward to form the discharge outlet. The width of the inlet is greater than the width of the discharge outlet, and the width of the discharge outlet is greater than the thickness of the zipper tape. The pre-expanded zipper tape is guided through the discharge channel and then fed into the machine.

[0008] In the feeding device of the zipper tape pre-expansion machine described above, the feeding chute also includes a receiving chute. The receiving chute is located at the bottom of the discharge port. The width of the receiving chute is greater than or equal to the width of the discharge port. The width of the receiving chute is greater than the width of the whole material chute. The receiving chute and the whole material chute have an arc transition. The lower stop of the zipper tape extends out of the discharge channel and passes through the receiving chute.

[0009] In the feeding device of the zipper tape pre-expansion machine described above, the feeding device further includes a receiving movable plate and a receiving cylinder. The receiving movable plate is located on the side of the discharge port. The receiving movable plate is inclined and connected to the receiving cylinder. It also includes a sensor. When the sensor detects that the bottom stop of the zipper tape has passed through the receiving slide, the sensor transmits a command to the receiving cylinder, causing the receiving cylinder to drive the receiving movable plate forward. The receiving movable plate presses against the side wall of the discharge port, causing the width of the discharge port to continuously shrink until the width of the discharge port is less than the width of the zipper and the same as the width of the material slide. After the zipper tape extends out of the discharge channel, it contacts the top surface of the receiving movable plate. The suspended zipper tape moves onto the material slide after being guided by the inclined receiving movable plate.

[0010] Compared with existing technologies, in the feeding device of this zipper tape pre-expansion machine, the bottom stop of the zipper tape first passes through the pre-expansion device, extends out of the discharge channel, and then passes through the receiving slide. Next, the sensor transmits a command to the receiving cylinder, causing the receiving cylinder to drive the receiving movable plate forward. The receiving movable plate squeezes the side wall of the discharge port, causing the width of the discharge port to continuously shrink until the width of the discharge port is less than the width of the zipper and the same as the width of the material slide. After the zipper tape zipper extends out of the discharge channel, it contacts the top surface of the receiving movable plate. The suspended zipper tape is guided by the inclined receiving movable plate and moves to the material slide. The zipper tape zipper contacts the top surface of the material slide, causing the zipper tape to hang on the material slide and move downward with the material slide until it contacts the limiting block, waiting for the subsequent feeding claw structure to remove it or waiting for manual removal. This ensures that the zipper tape is in a neat and straight hanging state when it is removed, making the arrangement more neat and convenient for subsequent storage and packaging.

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1-5 As shown, the zipper belt pre-expansion machine includes a frame 1 and a zipper belt. The zipper belt includes a chain, a top stop, a bottom stop, and a zipper lock. The top and bottom stops are located at both ends of the chain, and their sides protrude from the chain. The frame 1 is equipped with a feeding device 2, a pre-expansion device 3, a discharge device 4, and a heating device 5. The feeding device 2 transmits the zipper belt to the pre-expansion device 3. The heating device 5 is located below the feeding device 2 and heats the zipper belt during the feeding process. The pre-expansion device 3 includes a front pressure roller group 31 and a rear pressure roller group 32. The speed of the front pressure roller group 31 is greater than that of the rear pressure roller group 32. The zipper belt is conveyed from the rear pressure roller group 32 to the front pressure roller group 31. The differential speed setting between the front pressure roller group 31 and the rear pressure roller group 32 pre-expands the zipper belt. After pre-expansion and cooling, the zipper belt forms an inner arc feature. After pre-expansion, the zipper belt is discharged through the discharge device 4. In this application, the heating device 5 first heats the zipper belt and then pre-expands and shapes it through the differential transmission between the front pressure roller group 31 and the rear pressure roller group 32. The inner arc of the zipper belt is not easily deformed after shaping. The zipper belt with inner arc characteristics after shaping improves the quality of the zipper belt and prevents it from arching during use.

[0019] In the above technical solution: the feeding device 2 includes a feeding power source, a feeding hook 21, a feeding pressure foot 22, and two opposing zipper limiting plates 23. The frame 1 includes a feeding table 11, on which the zipper belt is placed. The lower stop side protrudes from the zipper belt to form a step, which abuts against the feeding hook 21. The feeding power source drives the feeding hook 21 and the zipper belt to move towards the pre-expansion device 3. During the movement, the zipper belt is located between the two zipper limiting plates 23, so that the zipper belt does not shift during the movement. The bottom of the feeding pressure foot 22 presses down on the zipper belt, making the zipper belt flatter during the movement and preventing the zipper belt from wrinkling during the movement.

[0020] In the above technical solution: the feeding power source includes a feeding motor 24, a feeding rack 25, a feeding gear, and a feeding guide slide 26. The feeding motor 24 and the feeding guide slide 26 are both fixed to the bottom of the feeding table 11. The feeding guide slide 26 has a guide channel inside, and a meshing opening is formed on the side of the guide channel. The feeding rack 25 passes through the guide channel and can move relative to the feeding guide slide 26 and the feeding table 11. The feeding gear is fixed on the output shaft of the feeding motor 24, and the feeding gear meshes with the feeding rack 25 through the meshing opening. The feeding hook 21 is fixed to one end of the feeding rack 25 near the pre-expansion device 3. The feeding motor 24 drives the feeding gear 25 to rotate, thereby driving the feeding rack 25 and the feeding hook 21 to move and feed material. Driven by the feeding motor 24, the feeding gear and feeding rack 25 transmit power, causing the feeding hook 21 to move the step and zipper belt against it. The transmission is stable and reliable, the structure is simple and the transmission is labor-saving. Furthermore, the moving speed of the zipper belt can be adjusted by adjusting the rotation speed of the output shaft of the feeding motor 24.

[0021] In the above technical solution: the feeding device 2 also includes a feeding stand 27 fixed on the frame 1 and two feeding base plates 28. The feeding pressure foot 22 includes a horizontal contact part and an arc-shaped elastic part, the top of which is fixed to the feeding stand 27. A hot air channel is formed between the two feeding base plates 28. The width of the hot air channel is smaller than the width of the zipper belt. The feeding hook 21 drives the zipper belt to move onto the hot air channel. The heating device 5 is located below the hot air channel and heats and shapes the zipper belt during the feeding process. The heating device 5 includes a hot steam nozzle. After the hot steam nozzle is activated, it sprays hot steam upward through the hot air channel to heat the zipper belt. The heating device 5 can also adopt other heating structures commonly found on the market. A heating device 5 is installed below the feeding device 2 to allow the zipper belt to be heated for a sufficient time. The zipper limiting plate 23 and the feeding foot 22 ensure that the zipper belt does not deform while being heated. The zipper belt is conveyed forward while being heated, allowing the zipper belt fabric fibers to fully expand and maintain a stable shape, thereby improving the pre-expansion and shaping effect of the pre-expansion device 3.

[0022] In the above technical solution: the front pressure roller group 31 includes a front upper pressure roller 311 and a front lower pressure roller arranged opposite each other and rolling synchronously; the rear pressure roller group 32 includes a rear upper pressure roller 321 and a rear lower pressure roller arranged opposite each other and rolling synchronously. The gap between the front upper pressure roller 311 and the front lower pressure roller and the gap between the rear upper pressure roller 321 and the rear lower pressure roller form a pre-expansion channel for the zipper tape. The front upper pressure roller 311 and the rear upper pressure roller 321 abut against the upper surface of the zipper tape, and the front lower pressure roller and the rear lower pressure roller abut against the lower surface of the zipper tape. Two front upper pressure rollers 311 are arranged side by side, abutting against the upper surface of the fabric on both sides of the zipper belt respectively; two front lower pressure rollers are arranged side by side, abutting against the lower surface of the fabric on both sides of the zipper belt respectively; correspondingly, two rear upper pressure rollers 321 are arranged side by side, abutting against the upper surface of the fabric on both sides of the zipper belt respectively; two rear lower pressure rollers are arranged side by side, abutting against the lower surface of the fabric on both sides of the zipper belt respectively.

[0023] In the above technical solution, the pre-expansion device 3 further includes a first drive mechanism for driving the front pressure roller group 31 to rotate and a second drive mechanism for driving the rear pressure roller group 32 to rotate. The first drive mechanism includes a first drive motor 33 and a first gear transmission assembly 34. The first gear transmission assembly 34 includes a first output gear 341, a first transmission gear 342, a first pressure roller gear 343, and a second pressure roller gear 344. The first output gear 341 is fixed on the output shaft of the first drive motor 33. The first transmission gear 342 meshes with the first output gear 341. The diameter of the first transmission gear 342 is larger than the diameter of the first output gear 341. The first pressure roller gear 343 is coaxially fixed with the first transmission gear 342 and the front lower pressure roller, respectively. The second pressure roller gear 344 meshes with the first pressure roller gear 343 and is coaxially fixed with the front upper pressure roller 311.

[0024] In the above technical solution: the second drive mechanism includes a second drive motor 35 and a second gear transmission assembly 36. The second gear transmission assembly 36 includes a second output gear 361, a second transmission gear 362, a third pressure gear 363, and a fourth pressure gear 364. The second output gear 361 is fixed on the output shaft of the second drive motor 35. The second transmission gear 362 meshes with the second output gear 361, and the diameter of the second transmission gear 362 is larger than the diameter of the second output gear 361. The third pressure gear 363 is coaxially fixed with the second transmission gear 362 and the lower rear pressure wheel, respectively. The fourth pressure gear 364 meshes with the third pressure gear 363 and is coaxially fixed with the upper rear pressure wheel 321. The first transmission gear 342 is staggered from the second transmission gear 362, the third pressure gear 363 is staggered from the first pressure gear 343, and the fourth pressure gear 364 is staggered from the second pressure gear 344.

[0025] The first drive motor 33 drives the first output gear 341 to rotate, and the first transmission gear 342 is driven to rotate synchronously, thereby driving the first pressure roller gear 343, the front lower pressure roller, the second pressure roller gear 344, and the front upper pressure roller 311 to rotate. The second drive motor 35 drives the second output gear 361 to rotate, and the second transmission gear 362 is driven to rotate synchronously, thereby driving the third pressure roller gear 363, the rear lower pressure roller, the fourth pressure roller gear 364, and the rear upper pressure roller 321 to rotate. The first drive motor 33 and the first gear transmission assembly 34 are each provided with two sets, driving two front upper pressure rollers 311 and two front lower pressure rollers respectively. The second drive motor 35 and the second gear transmission assembly 36 are each provided with two sets, driving two rear upper pressure rollers 321 and two rear lower pressure rollers respectively. The diameter of the first transmission gear 342 is larger than the diameter of the first output gear 341, and the diameter of the second transmission gear 362 is larger than the diameter of the second output gear 361, which increases the torque and reduces the speed.

[0026] In the above technical solution: the feeding device 4 includes a feeding channel 41, a receiving movable plate 42, a receiving cylinder 43, and two arc-shaped zipper guide rails 44. The feeding channel 41 is located at the tail of the pre-expansion device 3. The pre-expanded zipper tape is guided through the feeding channel 41 and then fed. The feeding channel 41 is arc-shaped and wider at the front and narrower at the back. The end of the feeding channel 41 closest to the pre-expansion device 3 is the feeding port 411. The two sides of the end of the feeding channel 41 away from the pre-expansion device 3 extend downward to form the feeding port 412. The bottom of the feeding port 411 is located below the front lower pressure roller, and the top of the feeding port 411 is located above the front upper pressure roller 311. The width of the feeding port 411 is greater than the width of the feeding port 412, and the width of the feeding port 412 is greater than the thickness of the zipper tape.

[0027] In the above technical solution: a downward-sloping arc-shaped feeding chute is formed between the two zipper guide rails 44. The feeding chute includes a receiving chute 441 and a material-carrying chute 442. The receiving chute 441 is located at the bottom of the discharge port 412. The width of the receiving chute 441 is greater than or equal to the width of the discharge port 412, ensuring that the lower stop portion extending from the discharge port 412 can smoothly pass through the receiving chute 441, ensuring smooth feeding. The width of the receiving chute 441 is greater than the width of the material-carrying chute 442, the width of the zipper is greater than the width of the material-carrying chute 442, and the width of the chain is greater than the width of the chain. The receiving chute 441 and the material-carrying chute 442 have an arc-shaped transition. A limiting block 443 is provided at the end of the material-carrying chute 442 to prevent the zipper belt on the material-carrying chute 442 from sliding out. The receiving chute 441 ensures that the lower stop portion can pass through the receiving chute 441.

[0028] In the above technical solution: the receiving cylinder 43 is fixed on the top surface of the frame 1, and the receiving movable plate 42 is located on the side of the discharge port 412. The receiving movable plate 42 is inclined and connected to the receiving cylinder 43. A sensor is also included, which can be fixed below the receiving slide 441. When the sensor detects that the bottom stop of the zipper belt has passed through the receiving slide 441, the sensor transmits a command to the receiving cylinder 43, causing the receiving cylinder 43 to move the receiving movable plate 42 forward. The receiving movable plate 42 presses against the side wall of the discharge port 412, causing the width of the discharge port 412 to continuously decrease until the width of the discharge port 412 is less than the width of the zipper and the same as the width of the material slide 442. This ensures that after the entire zipper belt is pre-expanded, it is in a suspended loading / unloading channel state, slides downward with the loading channel, and is limited and held in the loading channel by the limiting block 443. The sensor can also be fixed on the feeding stand 27 of the feeding device 2. When the sensor detects the pull of the zipper belt, it determines that the lower stop of the zipper belt has passed the pre-expansion device 3, the discharge channel 41 and the receiving slide 441 according to the length of the zipper belt, thereby transmitting the command to the receiving cylinder 43.

[0029] The bottom stop of the zipper tape first passes through the pre-expansion device 3, extends out of the discharge channel 41, and then passes through the receiving slide 441; then the sensor transmits a command to the receiving cylinder 43, causing the receiving cylinder 43 to drive the receiving movable plate 42 forward, and the receiving movable plate 42 presses against the side wall of the discharge port 412, causing the discharge port 412 to... The width of the zipper tape continues to decrease until the width of the discharge port 412 is less than the width of the zipper tape and the same as the width of the material chute 442. After the zipper tape extends out of the discharge channel 41, it contacts the top surface of the receiving movable plate 42. The suspended zipper tape moves to the material chute 442 after being guided by the inclined receiving movable plate 42. The zipper tape contacts the top surface of the material chute 442, so that the zipper tape is suspended on the material chute 442 and moves down with the material chute 442 until it contacts the limiting block 443, waiting for the subsequent unloading claw structure to take it away or waiting for manual material removal. This ensures that the zipper tape is in a neat and straight hanging state when the material is removed, making it more neat and convenient for subsequent storage and packaging.
