Description

Technical Field

[0001] This utility model relates to the technical field of bag opening machine accessory structure, and in particular to a bottom bag cloth fixing device for a bag opening machine. Background Technology

[0002] In garment manufacturing, pocket opening machines are essential auxiliary processing machinery, mainly used to create pockets in specific locations on garments for carrying small items such as mobile phones and wallets. The traditional method is to process the pocket opening and zipper separately first, and then sew the zipper or lip onto the pocket opening to complete the pocket opening.

[0003] Currently, regarding pocket sewing technology on the market, existing pocket opening machines encounter two difficulties when sewing pockets. The bottom pocket fabric is under the large pressure frame of the material fixing device. When the large pressure frame of the material fixing device lifts up to pick up the material, two problems arise. First, the bottom pocket fabric is pulled up and pressed down, causing wrinkles. When the large pressure frame moves along the X or Y axis, the bottom pocket fabric will wrinkle. Frequent wrinkles cause the bottom pocket fabric at non-stop edges to be sewn onto the cut piece when sewing the stop line. Second, when the pressure frame moves to pick up the material, the bottom pocket fabric fixed on the cut piece will affect the position of another piece of pocket fabric that has been placed.

[0004] To address the aforementioned shortcomings, utility model patent ZL202220783895.0 discloses a bag fabric catching mechanism for a bag opening machine. By setting a catching panel flush with the bag opening machine table, the catching panel can perform lifting and lateral movements relative to the bag opening machine table. However, the structure using the catching panel is cumbersome in its overall structure and operation, resulting in high costs and difficult maintenance. Now, a new structure has been developed that reduces material costs, has extremely high stability, strong fabric versatility, requires less maintenance, is convenient to use, and reduces overall costs. Summary of the Invention

[0005] The purpose of this invention is to provide a bottom bag fabric fixing device for a bag opening machine, which fixes the bottom bag fabric by means of a knife insert structure and a clamping plate structure, thereby simplifying the mechanical structure and configuration and reducing equipment costs.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a bottom bag fabric fixing device for a bag opening machine, comprising a material fixing device for the bag opening machine, which mainly consists of a large pressure frame and a small pressure frame, with processing windows opened on the large pressure frame and a fabric clamping guide groove located in front of the processing window on the large pressure frame; and a bottom bag fabric inserting knife mechanism is provided below the worktable in the bag opening machine.

[0026] The following description is only a preferred embodiment of the present utility model. The scope of protection is not limited to this embodiment. All technical solutions that fall within the scope of the present utility model should be protected by the present utility model. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present utility model should also be considered within the scope of protection of the present utility model.

[0027] It should be noted that in this document, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0028] The directional terms mentioned in this embodiment, such as "up," "down," "left," and "right," are merely used to help those skilled in the art understand the relationships between various features or parts in conjunction with the accompanying drawings. Example

[0029] like Figures 1 to 6 As shown, this utility model includes a material setting device 1 for a bag opening machine, which mainly consists of a large pressure frame 2 and a small pressure frame 3. Processing windows 4 are opened on the large pressure frame 2 and the small pressure frame 3. The material setting device 1 is arranged to slide back and forth, left and right, and up and down relative to the worktable 6. Its specific driving structure is existing technology and will not be described in detail in this embodiment. The material setting device 1 can be connected to the upper crossbeam of the bag opening machine, or the driving mechanism can be set on the worktable 6 without being fixed to the upper crossbeam. A fabric clamping guide groove 5 is opened on the large pressure frame 2 in front of the processing window 4. The width of the fabric clamping guide groove 5 is approximately more than twice the thickness of the bottom bag fabric, so that the folded bottom bag fabric can pass through. The number of fabric clamping guide grooves 5 can be a single one or two arranged side by side. A bottom bag fabric inserting knife mechanism 7 is set below the worktable 6 in the bag opening machine. The bottom bag fabric inserting knife mechanism 7 can be set below the material setting device 1 in the initial state of the bag opening machine, or it can be set below the bag folding device.

[0030] The bottom bag fabric inserting knife mechanism 7 includes a bottom bag fabric inserting knife 8 that is raised and lowered. The number, shape and size of the bottom bag fabric inserting knife 8 correspond to the fabric clamping guide groove 5, so that when the bottom bag fabric inserting knife 8 rises, it can pass through the worktable 6 and enter the fabric clamping guide groove 5.

[0031] The large pressure frame 2 is equipped with clamping pieces 9 for holding the bottom bag fabric. There can be one or two clamping pieces 9, which can be driven by a drive source or clamped using an elastic reset device during reset. The bottom bag fabric is fixed by the cooperation of the inserting knife structure and the clamping plate structure. After the bottom bag fabric is sewn to the cut piece, before the large pressure frame 2 is raised, the bottom bag fabric inserting knife 8 rises along the Z-axis to insert the bottom bag fabric into the clamping guide groove 5 of the large pressure frame. The clamping piece 9 presses down on the inserted part of the bottom bag fabric. The bottom bag fabric inserting knife 8 descends along the Z-axis, fixing the bottom bag fabric in the clamping guide groove 5. The bottom bag fabric can be sewn without wrinkles and does not interfere with the position of another piece of bag fabric. Compared with the prior art, this utility model eliminates the need for a material-holding panel and the drive and guide structures for driving the material-holding panel to rise, fall, and move laterally, greatly reducing equipment costs. Since the other end of the bottom bag fabric is already sewn and fixed to the bag opening, the bottom bag fabric will directly follow the displacement movement of the material-holding device and remain flat at all times.

[0032] Specifically, the clamping piece 9 is mounted on the large pressure frame 2 in a back-and-forth or up-and-down swing manner. When the clamping piece 9 is a single piece, it uses its back-and-forth movement to cooperate with the clamping guide groove 5 to clamp the bottom bag fabric. When there are two clamping pieces 9, the two clamping pieces 9 move in opposite directions to clamp the bottom bag fabric, or one piece is fixed and the other moves back and forth to achieve the clamping action. The clamping piece 9 can also be swing-mounted, using the swing action to open the clamping guide groove 5. When the bottom bag fabric is inserted, the clamping piece 9 swings to clamp the inserted part.

[0033] In this embodiment, a single piece is used, moving back and forth. Specifically, the clamping piece 9 is connected to the clamping cylinder 10, and the clamping cylinder 10 drives the clamping piece 9 to move back and forth on the clamping guide groove 5. The clamping cylinder 10 is fixed on the large pressure frame 2.

[0034] The clamping piece 9 has a clamping groove corresponding to the clamping guide groove 5. When the clamping groove and the clamping guide groove 5 are aligned, it is convenient to insert the bottom bag cloth. After the clamping piece 9 moves, the clamping groove and the clamping guide groove 5 are misaligned, thereby fixing the bottom bag cloth.

[0035] Specifically, the bottom bag fabric inserting knife mechanism 7 also includes an inserting knife cylinder 11 and a fixing plate 12. The inserting knife cylinder 11 is mounted on the fixing plate 12 and connected to the bottom bag fabric inserting knife 8.

[0036] Specifically, the bottom bag inserting knife mechanism 7 is fixed below the worktable 6 in the bag opening machine via the material holding bracket 13, so that the bottom bag inserting knife mechanism 7 is located below the material fixing device 1 in the initial state of the bag opening machine, or below the bag folding device, or it can be located below any position where the material fixing device 1 moves laterally.

[0037] Specifically, the two ends of the clamping piece 9 are connected to the clamping piece connecting rod 14, the clamping piece connecting rod 14 is connected to the clamping cylinder 10, the clamping cylinder 10 is fixed at the rear of the large pressure frame 2, the clamping piece 9 is located below the large pressure frame 2, and the large pressure frame 2 has a groove for accommodating the clamping piece connecting rod 14 and the clamping piece 9, so that the frame surface of the large pressure frame 2 is clean and interference between the various mechanisms is avoided.

[0038] During operation: After the first bottom pocket fabric is sewn, when the clamping guide groove 5 is directly above the bottom pocket fabric inserting knife 8, the inserting knife cylinder 11 extends to drive the bottom pocket fabric inserting knife 8 to rise, pushing the bottom pocket fabric into the clamping guide groove 5. At this time, the clamping cylinder 10 retracts and drives the bottom pocket fabric clamping piece 9 to move and clamp the fabric through the clamping piece connecting rod 14. The inserting knife cylinder 11 retracts and drives the bottom pocket fabric inserting knife 8 to descend, completing the clamping action. After the second material removal is completed, the clamping cylinder 10 extends and drives the bottom pocket fabric clamping piece 9 to move and release the fabric through the clamping piece connecting rod 14, completing the entire clamping and releasing action. Example

[0039] See Figure 7 The difference between this embodiment and embodiment one is only in the shape and size of the clamping piece 9 and the installation position of the clamping cylinder 10. In this embodiment, the clamping piece 9 is L-shaped, and its upper end is connected to the clamping cylinder 10. A groove is opened on the large pressure frame 2 to accommodate the bottom of the clamping piece 9. The clamping piece 9 is located in the groove, and the clamping cylinder 10 is fixed to the front end of the large pressure frame 2. Example

[0040] See Figure 8 and Figure 9 The difference between this embodiment and embodiment one is that the movement mode of the clamping piece 9 is different. The clamping piece 9 is connected to the clamping cylinder 10 and swings up and down to the front of the clamping guide groove 5. The clamping cylinder 10 is fixed on the large pressure frame 2. The clamping piece 9 is rotatably fixed on the large pressure frame 2 by a rotating rod. A sliding groove is opened on the clamping piece 9. The front end of the clamping piece connecting rod 14 is slidably engaged with the sliding groove by a locking head. After the clamping cylinder 10 drives the locking head to move back and forth, it will drive the clamping piece 9 to swing. When the bottom bag cloth is inserted, the clamping piece 9 swings to clamp the bottom bag cloth.

[0041] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
