Description

Technical Field

[0001] This utility model relates to the field of zipper processing technology, and more specifically, it relates to a zipper end pressing device for zipper processing. Background Technology

[0002] In the zipper production process, end pressing is a key step to ensure the stability of zipper use. After the zipper end is pressed and shaped by the processing device on the top of the workbench, the pressed zipper end needs to be collected in time by the collection mechanism to avoid the finished product from piling up at the end of the conveyor and to ensure the continuous operation of the production line.

[0003] An existing zipper end pressing device for zipper processing has been found to have the following issues during use:

[0004] Existing collection mechanisms rely on multiple sets of screws for locking or rigid connections with slide rails. When removing the finished product, one must first use a screwdriver to unscrew the side fixing screws or pull the collection box forcefully to overcome the frictional resistance of the slide rail. This makes it difficult to quickly remove the zipper at the end after pressing, and it takes a lot of time, resulting in poor practicality. Utility Model Content

[0008] To achieve the above objectives, this utility model provides the following technical solution: a zipper end pressing device for zipper processing, comprising an operating table, a processing device on the top of the operating table, a conveyor table on the left side of the processing device, a fixing plate on the left end of the operating table, an mounting plate on the left end of the fixing plate, a collection box on the top of the mounting plate, a working chamber in the collection box, a feed pipe on the top of the working chamber of the collection box, the feed pipe being located below the other end of the conveyor table, a pre-drilled hole at the bottom front end of the working chamber of the collection box, a collection box slidably fitted inside the pre-drilled hole of the collection box, and the outer rear end of the collection box slidably fitted against the inner wall of the working chamber of the collection box, a collection groove on the top of the collection box, a cover plate on the front end of the collection box, the rear end of the cover plate being tightly fitted against the front end of the collection box, positioning components on the front sides of both the left and right ends of the collection box, and both the left and right ends of the collection box being connected to the left and right ends of the cover plate through the positioning components, and a fixing mechanism on the top of the cover plate.

[0009] The present invention is further configured such that the fixing mechanism includes two sets of positioning plates, and positioning plates are provided on the left and right sides of the top of the cover plate. A fixing block is provided on the top of the front end of the collection box. The fixing block is provided with a working cavity, and an adjustment component is provided in the working cavity of the fixing block. Connecting screws are provided on both the left and right ends of the working cavity of the fixing block through the adjustment component. Fixing blocks are provided on both the left and right sides of the front end of the collection box. The opposite ends of the two sets of fixing blocks are rotatably connected to the other ends of the corresponding set of connecting screws. Threaded cylinders are threadedly connected to the outer sides of the two sets of connecting screws. Connecting blocks are provided on the outer sides of the two sets of threaded cylinders. The top and bottom of one end of the two sets of connecting blocks are provided with... The four sets of positioning plates have pre-drilled holes at their top and bottom. The inner sides of the pre-drilled holes of the four sets of positioning plates are respectively engaged with the outer sides of the corresponding set of locking blocks. The rear ends of the two sets of connecting blocks are equipped with guide components. The adjustment component drives the connecting screw and the threaded cylinder to achieve automatic locking and unlocking of the locking blocks and positioning plates. There is no need for manual alignment of the locking blocks and pre-drilled holes. Only the adjustment component needs to be operated to complete the fixing and unlocking, which further simplifies the process of removing the collection box and improves efficiency. The cooperation of the four sets of locking blocks and the pre-drilled holes of the positioning plates forms multi-point fixation to ensure that the cover plate and the collection box are firmly connected. Even if the processing device vibrates during operation, the cover plate will not shift, preventing the collection box from slipping.

[0010] The present invention is further configured such that the adjusting component includes a rotating rod, and the working cavity of the fixed block is provided with first through holes at both ends. The inner sides of the first through holes of the two sets of fixed blocks are respectively rotatably connected to the outer sides of a corresponding set of connecting screws, and the rear end of the rotating rod is rotatably connected to the rear end of the working cavity of the fixed block. The front end of the working cavity of the fixed block is provided with a second through hole, and the inner side of the second through hole of the working cavity of the fixed block is rotatably connected to the outer side of the rotating rod. The rear end of the outer side of the rotating rod is provided with a driving bevel gear, and the outer sides of the two sets of connecting screws are provided with driven bevel gears on opposite sides, and the front ends of the two sets of driven bevel gears are meshed with the rear end of the driving bevel gear. The bevel gear transmission structure realizes the synchronous transmission of power from the rotating rod to the two sets of connecting screws. The rotating rod is simple to operate and requires no special tools. Even ordinary operators on the assembly line can easily master it, reducing the operating threshold. The meshing transmission accuracy of the driving bevel gear and the driven bevel gear is high, reducing the transmission gap and ensuring that the locking block can be accurately locked into the reserved hole every time, avoiding fixing failure due to transmission error, and further improving the reliability of the fixing mechanism.

[0011] The present invention is further configured such that the guiding component includes two sets of mounting blocks, and mounting blocks are provided on both the left and right sides of the front end of the collection box. Each set of mounting blocks has a sliding groove at its front end, and a guide block is slidably disposed in each of the sliding grooves of the two sets of mounting blocks. The front ends of the two sets of guide blocks are respectively connected to the rear ends of a corresponding set of connecting blocks. The cooperation between the guide blocks and the sliding grooves of the mounting blocks provides precise guidance for the movement of the connecting blocks, ensuring that the locking block can accurately engage with the reserved hole of the positioning plate each time, thereby improving the success rate of the fixing mechanism.

[0012] The present invention is further configured such that the positioning component includes two sets of T-shaped strips, and connecting plates are provided on both the left and right sides of the rear end of the cover plate.

[0029] Please see Figure 1-5 A zipper end pressing device for zipper processing includes an operating table 1, a processing device 2 on the top of the operating table 1, a conveyor table 3 on the left side of the processing device 2, a fixing plate 4 on the left end of the operating table 1, an mounting plate 5 on the left end of the fixing plate 4, a collection box 6 on the top of the mounting plate 5, a working chamber in the collection box 6, a feed pipe 7 on the top of the working chamber of the collection box 6, and the feed pipe 7 is located below the other end of the conveyor table 3. A pre-drilled hole is provided at the bottom front end of the working chamber of the collection box 6, a collection box 8 is slidably fitted inside the pre-drilled hole of the collection box 6, and the rear end of the outer side of the collection box 8 is slidably fitted to the inner wall of the working chamber of the collection box 6. A collection groove 9 is provided on the top of the collection box 8, a cover plate 10 is provided at the front end of the collection box 8, and the rear end of the cover plate 10 is tightly fitted to the front end of the collection box 6. Positioning components are provided on the front sides of both the left and right ends of the collection box 6, and both the left and right ends of the collection box 6 are connected to the left and right ends of the cover plate 10 through the positioning components. A fixing mechanism is provided on the top of the cover plate 10.

[0030] In this embodiment, during the zipper end pressing process, the processing device 2 on the top of the operating table 1 presses the zipper end. The pressed zipper end is then conveyed to the end via the conveyor 3 on the left side of the processing device 2. Subsequently, it falls from the other end of the conveyor 3 into the feed pipe 7 at the top of the working chamber of the collection box 6 below. It then enters the collection box 8 inside the working chamber of the collection box 6 through the feed pipe 7 and finally accumulates in the collection groove 9 at the top of the collection box 8.

[0031] When the zipper ends in the collection box 8 accumulate to a certain amount and need to be removed, first operate the fixing mechanism at the top of the cover plate 10 to release the locking mechanism between the cover plate 10 and the collection box 6. Then operate the positioning components on the front of the left and right ends of the collection box 6 to release the connection restriction between the positioning components and the cover plate 10 and the collection box 6. Then pull the cover plate 10, and the cover plate 10 will drive the collection box 8 to slide along the inside of the reserved hole of the collection box 6 to remove the collection box 8 from the working cavity of the collection box 6 and empty the zipper ends in the collection slot 9. After cleaning, slide the collection box 8 back into the reserved hole of the collection box 6 and fix the cover plate 10 through the positioning components and fixing mechanism to restore the collection function.

[0032] More specifically, when installing the cover plate 10, the rear end of the cover plate 10 is attached to the front end of the collection box 6, and the cover plate 10 is pushed to move towards the collection box 6. The connecting plates 24 on the left and right sides of the rear end of the cover plate 10 drive the T-shaped strips 23 to move synchronously, so that the two sets of T-shaped strips 23 gradually engage with the slots on the front sides of the left and right ends of the collection box 6, completing the initial positioning of the cover plate 10 and the collection box 6. Then, the cover plate 10 is further fixed by the fixing mechanism.

[0033] Please see Figure 1 and Figure 4 As one implementation of the fixing mechanism: the fixing mechanism includes two sets of positioning plates 11. Positioning plates 11 are provided on the top left and right sides of the cover plate 10. A fixing block 12 is provided on the top front end of the collection box 6. The fixing block 12 is provided with a working cavity. An adjustment component is provided in the working cavity of the fixing block 12. Connecting screws 13 are provided on both the left and right ends of the working cavity of the fixing block 12 through the adjustment component. Fixing blocks 12 are provided on both the left and right sides of the front end of the collection box 6. The two sets of fixing blocks 12 are rotatably connected to the other end of the corresponding set of connecting screws 13 at opposite ends. Threaded cylinders 14 are threadedly connected to the outer sides of the two sets of connecting screws 13. Connecting blocks 16 are provided on the outer sides of the two sets of threaded cylinders 14. Locking blocks 17 are provided at the top and bottom of one end of the two sets of connecting blocks 16. Reserved holes are provided at the top and bottom of one end of the two sets of positioning plates 11. The inner sides of the reserved holes of the four sets of positioning plates 11 are respectively locked to the outer sides of the corresponding set of locking blocks 17. Guide components are provided at the rear ends of the two sets of connecting blocks 16.

[0034] Specifically, when fixing the cover plate 10, first attach the cover plate 10 to the front end of the collection box 6, so that the positioning plates 11 on the left and right sides of the top of the cover plate 10 are aligned with the fixing blocks 12 at the front end of the collection box 6. Then, operate the adjustment component in the working cavity of the fixing block 12 at the top of the front end of the collection box 6. The adjustment component drives the connecting screws 13 at both ends of the working cavity of the fixing block 12 to rotate. The other end of the connecting screw 13 rotates stably in the fixing blocks 12 on the left and right sides of the front end of the collection box 6. The threaded cylinder 14 on the outside of the connecting screw 13 moves along the screw axis as the screw rotates. The connecting block 16 on the outside of the threaded cylinder 14 moves synchronously with the threaded cylinder 14. The guide component at the rear end of the connecting block 16 ensures that the connecting block 16 moves smoothly.

[0035] When the connecting block 16 moves, the top and bottom locking blocks 17 of one end gradually approach the positioning plate 11 until the four sets of locking blocks 17 are respectively locked into the inner side of the corresponding reserved holes of the positioning plate 11, thus completing the fixing of the cover plate 10 and the collection box 6.

[0036] Please refer to Figures 2-4As a further embodiment of the fixing mechanism: the adjusting component includes a rotating rod 18, and the working chamber of the fixing block 12 is provided with first through holes at both ends. The inner sides of the first through holes of the two sets of fixing blocks 12 are respectively rotatably connected to the outer sides of a corresponding set of connecting screws 13, and the rear end of the rotating rod 18 is rotatably connected to the rear end of the working chamber of the fixing block 12. The front end of the working chamber of the fixing block 12 is provided with a second through hole, and the inner side of the second through hole of the working chamber of the fixing block 12 is rotatably connected to the outer side of the rotating rod 18. The outer rear end of the rotating rod 18 is provided with a driving bevel gear 19, and the outer opposite sides of the two sets of connecting screws 13 are each provided with a driven bevel gear 20, and the front ends of the two sets of driven bevel gears 20 are meshed with the rear end of the driving bevel gear 19.

[0037] The guide assembly includes two sets of mounting blocks 21. Mounting blocks 21 are provided on both the left and right sides of the front end of the collection box 6. The front end of each set of mounting blocks 21 is provided with a sliding groove. Guide blocks 22 are slidably arranged in the sliding grooves of each set of mounting blocks 21. The front ends of the two sets of guide blocks 22 are respectively connected to the rear end of a corresponding set of connecting blocks 16.

[0038] Specifically, the rotating rod 18 inside the second through hole at the front end of the working cavity of the rotating fixed block 12 rotates stably at the rear end of the working cavity of the fixed block 12. The driving bevel gear 19 at the outer rear end of the rotating rod 18 rotates synchronously with the rotating rod 18. One side of the rear end of the driving bevel gear 19 meshes with the driven bevel gear 20 on the opposite side of the outer side of the two sets of connecting screws 13, driving the two sets of driven bevel gears 20 to rotate synchronously in opposite directions. The driven bevel gear 20 drives the corresponding connecting screw 13 to rotate inside the first through hole of the fixed block 12, thereby driving the threaded cylinder 14 and the connecting block 16 to move, realizing the locking or disengaging of the locking block 17.

[0039] When the connecting block 16 moves with the threaded cylinder 14, the guide block 22 at the rear end of the connecting block 16 slides synchronously along the sliding grooves of the mounting blocks 21 on the left and right sides of the front end of the collection box 6. The guide block 22 is always confined within the sliding groove to prevent the connecting block 16 from shifting up or down or left or right when it moves, and to ensure that the connecting block 16 drives the locking block 17 to always be aligned with the reserved hole direction of the positioning plate 11.

[0040] In summary, the overall equipment is in use (or running):

[0041] After the processing device 2 on the top of the operating table 1 presses the zipper end together, the finished product is conveyed to the end through the conveyor table 3 on the left side of the processing device 2. It falls from the other end of the conveyor table 3 into the feed pipe 7 at the top of the working chamber of the collection box 6 below, enters the collection box 8 inside the collection box 6 through the feed pipe 7, and accumulates in the collection groove 9 at the top of the collection box 8.

[0042] When the collection box 8 needs to be removed, first hold the rotating handle 15 at the front end of the rotating rod 18. The driving bevel gear 19 on the outside of the rotating rod 18 meshes with the driven bevel gears 20 of the two sets of connecting screws 13, so that the connecting screws 13 rotate in the fixing block 12 at the front end of the collection box 6. The threaded cylinder 14 drives the connecting block 16 and slides along the slide groove of the mounting block 21 through the guide block 22. The locking block 17 disengages from the reserved hole of the positioning plate 11 of the cover plate 10. Hold the pull handle 25 at the front end of the cover plate 10 to release the locking between the slot of the collection box 6 and the T-shaped strip 23 of the connecting plate 24 of the cover plate 10 until the cover plate 10 is pulled to drive the collection box 8 to slide out along the reserved hole of the collection box 6 and pour out the finished product in the collection trough 9.

[0043] After cleaning, slide the collection box 8 back into the reserved hole of the collection box 6, insert the T-shaped strip 23 into the slot, rotate the handle 15 in the opposite direction to make the locking block 17 lock into the reserved hole of the positioning plate 11 to fix the cover plate 10 and restore the collection function.

[0044] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
