Description

Technical Field

[0001] This application relates to the technical field of sewing equipment, and in particular to a sewing equipment for producing zipper tape. Background Technology

[0002] Zippers are one of the most commonly used opening and closing tools in modern life. Due to their quick opening and closing, beautiful appearance and convenience, they have penetrated into all aspects of life and are widely used in clothing accessories, bags, home furnishings, protective equipment and other fields.

[0003] A zipper sewing machine is a device specifically designed to attach zippers to fabric or other materials. A zipper sewing machine includes a frame, a base on the frame, and a sewing device on the frame. The sewing device is used to sew two zipper teeth to a fabric strip. A zipper head is fixedly connected to the base. After the zipper teeth are sewn onto both fabric strips, the two zipper teeth are passed through the zipper head and closed together.

[0004] During the process of merging the two teeth on the fabric tape with the zipper head, the zipper head is constantly worn down by the fabric tape and the teeth. After prolonged use, the zipper head is prone to damage. Since the zipper head is fixed to the machine base of the zipper sewing machine, the damaged zipper cannot be replaced separately. The entire machine base welded to the zipper head must be replaced, which results in high replacement costs. Utility Model Content

[0005] To address the issue that the machine base welded to the zipper head can only be replaced as a whole when the zipper is damaged, this application provides a zipper tape production sewing device.

[0006] This application provides a zipper tape production sewing machine, which adopts the following technical solution:

[0007] A zipper tape production sewing device includes a frame, a machine head mounted on top of the frame, a sewing platform on the machine head, and a sewing structure for sewing two zipper teeth onto a fabric tape. The sewing platform has a storage slot containing a receiving box. The receiving box has a zipper head mounted on it. The side of the receiving box has a receiving groove, and a cover plate is provided on the side wall of the receiving box to cover the receiving groove. A movable column movable in a vertical direction is provided between two horizontally opposite inner walls of the receiving groove. The zipper head includes a connector for joining or separating the two zipper teeth and a zipper piece. A slot is provided above the receiving box, and the bottom wall of the slot has a ring post for the zipper head. The zipper pull has an insertion hole through which it passes. A connecting structure is provided on the zipper pull, which is connected to a movable post via the connecting structure. The connecting structure includes a first connecting post, a second connecting post, and a connecting block. Both the first and second connecting posts are connected to the end of the zipper pull away from the connecting member. The first connecting post is located on the side of the second connecting post near the bottom wall of the receiving groove. The movable post is located between the first and second connecting posts. A stop is provided on the side of the second connecting post facing the first connecting post. The end of the first connecting post facing the second connecting post is rotatably connected to the connecting block. The stop is located on the path of the connecting block rotating away from the zipper pull. When the zipper pull and the movable post are connected via the connecting structure, the connecting block is located below the movable post.

[0008] By adopting the above technical solution, the receiving box is removed from the storage slot. The zipper head's ring and zipper piece both pass through the insertion hole. During the connection process between the zipper piece and the movable column, the connecting block rotates towards the zipper head. When the connecting block abuts against the inner wall of the zipper piece, the movable column rises and moves between the first and second connecting columns. When the movable column no longer obstructs the connecting block's reverse rotation and reset, the connecting block rotates away from the zipper head. As the connecting block continues to rotate in the horizontal direction, it is blocked by the stop block. The movable column descends and abuts against the connecting block, thus connecting the zipper head to the receiving box. Conversely, the movable column is driven to rise, and the connecting block is rotated again. Then, the movable column is moved below the stop block, releasing the connection between the movable column and the zipper piece. At this point, the zipper head can be removed from the receiving box and replaced. The above process allows for the replacement of the zipper head without replacing the entire machine base, thus reducing costs.

[0009] Optionally, the movable column is provided with sliders at both ends along its length, and the two horizontally opposite inner walls of the receiving box are provided with vertical guide rails. The guide rails are provided with vertically elongated grooves on the side facing the movable column, and the sliders are slidably disposed in the grooves. The sliders can slide vertically along the guide rails.

[0010] By adopting the above technical solution, the slider moves along the length of the guide rail, which plays a guiding role; the sliders at both ends of the movable column drive the movable column to slide up and down along the guide rail. When it is necessary to disassemble the movable column from the zipper piece, the movable column is slid upward along the guide rail to ensure that the connecting block has enough space to rotate in the direction close to the connector. When the connecting block abuts against the zipper piece, the movable column is slid downward to separate the movable column from the zipper piece, which is convenient for replacing the zipper head.

[0011] Optionally, a positioning hole is provided on the side of the guide rail, and a positioning bolt is threaded into the positioning hole; when the lower end of the positioning bolt abuts against the upper end face of the slider, the lower end of the slider abuts against the lower inner wall of the slide groove.

[0012] By adopting the above technical solution, after the movable column is connected to the zipper piece, tightening the positioning bolt will cause the lower end of the positioning bolt to abut against the upper end face of the slider, and the lower end of the slider to abut against the lower inner wall of the slide groove. This will prevent the movable column from moving along the guide rail due to the vibration of the sewing machine, and reduce the probability of displacement of the connecting parts due to the movement of the movable column.

[0013] Optionally, a connecting block is provided on the sewing platform, and a connecting hole is opened on the horizontal side of the connecting block. A rotating column is rotatably connected in the connecting hole, and the length direction of the rotating column is perpendicular to the transmission direction of the chain teeth on the sewing platform.

[0014] By adopting the above technical solution, the fabric tape moves around the rotating post before moving to the sewing area. Using the rotating post can reduce the wear of the fabric tape.

[0015] Optionally, the sewing head further includes a body mounted on the sewing platform. The body is provided with a transport structure, which includes a fixed block mounted on the side of the body, a lifting bolt threaded onto the fixed block, a lifting frame rotatably connected to the lower end of the lifting bolt, a first roller rotatably connected to the lifting frame, a second roller located directly below the first roller, and a drive source for driving the second roller to rotate. The upper end of the sewing platform is provided with a fixed groove, which is located on the side of the zipper head away from the fabric feeding direction. The drive source is fixedly connected to the bottom wall of the fixed groove, and the output shaft of the drive source is connected to the second roller, with the second roller extending out of the fixed groove.

[0016] By adopting the above technical solution, the drive source drives the second roller to rotate. The second roller cooperates with the first roller to transfer the product between the two. When the first roller and the second roller rotate, they can press the fabric tape with sewn chain teeth, increasing the firmness of the fabric tape and chain teeth.

[0017] Optionally, the side of the frame is provided with a flattening structure for flattening the fabric strip. The flattening structure includes a support plate on the side of the frame, two upright plates above the support plate, an upper pressure plate and a lower pressure plate between the two upright plates, and a gap is left between the upper pressure plate and the lower pressure plate for the fabric to pass through. The upright plates are provided with adjustment components for adjusting the distance between the upper pressure plate and the lower pressure plate.

[0018] By adopting the above technical solution, the fabric belt is flattened by the upper and lower pressure plates as it passes through the gap between the upper and lower pressure plates, making the connection between the fabric belt and the chain teeth more precise.

[0019] Optionally, the adjusting assembly includes a horizontal plate and a fixing bolt. The horizontal plate is placed above the vertical plate. The end of the horizontal plate away from the upper pressure plate has a threaded hole for the fixing bolt to pass through. The threaded hole is threadedly connected to the fixing bolt. The fixing bolt is rotatably connected to the end of the upper pressure plate near the horizontal plate.

[0020] By adopting the above technical solution, the fixing bolt is rotatably connected to the upper pressure plate. Rotating the fixing bolt will cause the upper pressure plate to rise, thereby increasing the distance between the upper and lower pressure plates. Conversely, rotating the fixing bolt in the opposite direction will cause the upper pressure plate to fall, thereby reducing the distance between the upper and lower pressure plates. This allows the flattening structure to flatten fabrics of different thicknesses.

[0021] Optionally, the flattening structure further includes a connecting rod located on the side of the upright plate away from the frame. The end of the connecting rod away from the upright plate is bolted to a round rod, and the length direction of the round rod is consistent with the length direction of the upper pressure plate.

[0022] By adopting the above technical solution, the fabric enters the flattening structure through the round rod, reducing the friction force on the fabric when passing through the flattening structure and reducing fabric wear.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Both the zipper head's ring post and the zipper piece pass through the insertion hole. During the connection process between the zipper piece and the movable post, the connecting block rotates towards the zipper head. When the connecting block abuts against the inner wall of the zipper piece, the movable post can pass through the gap created by the movement of the connecting block. The movable post continues to move away from the connecting block, causing the connecting block to rotate away from the zipper head. As the connecting block rotates to the horizontal direction and continues to rotate, it is blocked by the stop block. The movable post descends and is blocked by the connecting block, preventing the zipper piece from passing through. The zipper piece and the movable post are detachably connected and placed in the receiving box. If the zipper head is damaged during use, the receiving box in the storage slot can be removed to replace the zipper head without replacing the entire machine base, thus reducing costs.

[0025] 2. The fabric tape enters the flattening structure through the round rod, which can reduce the friction force on the fabric when passing through the flattening structure and reduce the degree of fabric wear; before entering the sewing area, the fabric tape passes around the rotating column and then moves to the sewing area. Using the rotating column to transport the fabric tape can reduce the degree of fabric tape wear. Attached Figure Description

[0057] The implementation principle of a zipper tape production sewing device according to an embodiment of this application is as follows: During the disassembly of the zipper piece 292 and the movable post 2511, the receiving box 24 is first removed from the storage slot 23, then the cover plate 26 is removed, the movable post 2511 in the receiving slot 25 is driven to rise, and the connecting block 29213 is rotated to rotate towards the zipper head 29. When the connecting block 29213 abuts against the inner wall of the zipper piece 292, the movable post 2511 is moved downward and removed from the gap between the first connecting post 29211 and the second connecting post 29212, thereby releasing the connection between the movable post 2511 and the zipper piece 292. The ring post 2912 and the zipper piece 292 in the insertion hole 28 are then removed from the insertion hole 28, and the zipper head 29 is removed from the receiving slot 25, so that the zipper head 29 can be replaced.

[0058] During the replacement of the new zipper head 29, the new zipper head 29 is placed in the insertion hole 28 of the receiving box 24, so that the ring post 2912 on the connector 291 and the zipper piece 292 pass through the insertion hole 28. During the connection of the zipper piece 292 and the movable post 2511, the driving connecting block 29213 is rotated towards the zipper head 29. When the connecting block 29213 abuts against the inner wall of the zipper piece 292, the movable post 2511 rises and is moved between the first connecting post 29211 and the second connecting post 29212. The driving of the movable post 2511 continues. As the zipper head 29 rotates upward, the movable column 2511 no longer obstructs the connecting block 29213 from rotating and resetting away from the zipper head 29. The movable column 2511 rotates and resets. After the connecting block 29213 rotates to the horizontal position, it will be blocked by the stop block 29214 during its continued rotation. At this time, the movable column 2511 is driven to descend and abuts against the connecting block 29213, thus connecting the zipper head 29 to the receiving box 24. The cover plate 26 is then placed on top to cover the receiving groove 25, and the receiving box 24 is placed in the storage groove 23 and fixed, thus enabling the replacement of the zipper head 29.
