Description

Technical Field

[0001] This utility model relates to the field of garment processing technology, and in particular to a pocket folding and shaping device for a pocket opening machine. Background Technology

[0002] In the garment manufacturing process, pocket opening machines are essential auxiliary processing machinery. They are mainly used to form pockets in specific locations on the garment to facilitate carrying small items such as mobile phones and wallets. The current common practice is to process the pocket opening and the pocket lip (which can also be a zipper, the same below) separately first, and then sew the pocket lip onto the pocket opening to complete the pocket opening.

[0003] Specifically, the garment is first placed on a large pressing frame, and then pressed down on a small pressing frame to press the garment material onto the fixed piece of the large pressing frame, which can move and stretch, in order to fix the garment material. Then, the pockets of the garment are cut, folded, shaped, and sewn. Cutting means cutting a slit (such as a "Y" shaped slit) at the pocket. Folding the pocket means folding the cut pocket opening inward along the edge of the fixed piece to form a folded edge, and using clips to press the fixed piece upward to hold and fix the folded edge of the pocket. Shaping the folded edge means placing and pressing the folded edge of the pocket onto the folded edge of the pocket. Finally, the garment is sewn.

[0004] However, during the above process, the small pressure frame has to press down on the fixed piece each time. After a certain processing time, the fixed piece is prone to loosening at its installation point due to frequent pressure, which in turn affects the processing quality and stability of the pocket. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a pocket folding and shaping device for a bag opening machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pocket flap shaping device for a bag opening machine includes a large pressure frame fixed to a mounting base and a small pressure frame lifted and lowered above the large pressure frame. The large pressure frame is provided with front and rear material fixing plates that can form a material fixing window. The front and rear material fixing plates have deformable ends extending toward the material fixing window. The small pressure frame is provided with a pressure plate for pressing against the deformable ends. A clamping piece that is openable and closable is installed below the large pressure frame.

[0008] Preferably, there are two pressure plates distributed in a front-to-back manner, and at least one of the pressure plates can be driven and move up and down relative to the small pressure frame.

[0009] Preferably, the pressure plate is provided with a bent portion extending toward the deformation end and a pressure strip connected to the bent portion and capable of pressing against the deformation end.

[0010] Preferably, the pressing strip is long and extends along the length direction of the deformed end.

[0011] Preferably, the large pressure frame is provided with a fixed plate that can slide back and forth, and one side of the front and rear fixed material pieces is fixedly installed on the fixed plate.

[0012] Preferably, a drive cylinder is installed on the large pressure frame, and a drive plate that can drive the fixed plate to slide back and forth is connected to the drive end of the drive cylinder.

[0013] Preferably, a clamping cylinder is installed on the large pressure frame, and the clamping plate is connected to the driving end of the clamping cylinder and can be driven to move up and down.

[0014] The beneficial effects of this utility model are:

[0015] When the pressure plate of the small pressure frame is driven to press down on the garment, the deformation ends of the front and rear fixed pieces can be stressed and deform slightly downwards, pressing tightly against the clamping piece. This allows the pressure plate, the front and rear fixed pieces, and the clamping piece to be pressed together more tightly and evenly, thereby improving the clamping effect on the garment pocket and ensuring the subsequent processing quality and stability of the pocket. At the same time, the deformation setting through the stress on the deformation ends avoids the stability of the front and rear fixed pieces installation being affected by frequent pressure, thus improving the reliability of pocket processing.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] like Figures 1-6 As shown, a pocket folding and shaping device for a bag opening machine includes a large pressure frame 2 fixed to a mounting base 1 and a small pressure frame 3 that is lifted and lowered above the large pressure frame 2. In this embodiment, the small pressure frame 3 is slidably lifted and lowered on the mounting base 1, and the small pressure frame 3 can be driven and slide and move relative to the large pressure frame 2.

[0026] The large pressure frame 2 is provided with front and rear material fixing pieces 24 that can form a material fixing window 25. There are two front and rear material fixing pieces 24, which are slidably disposed on the large pressure frame 2. The material fixing window 25 is formed between the two front and rear material fixing pieces 24. The front and rear material fixing pieces 24 have deformable ends 241 extending toward the material fixing window 25. It can also be understood that one side of the front and rear material fixing pieces 24 is slidably connected to the large pressure frame 2, and the deformable ends 241 on the other side of the front and rear material fixing pieces 24 are suspended vertically.

[0027] The small pressure frame 3 is provided with a pressure plate 31 for pressing against the deformed end 241. Specifically, the pressure plate 31 is provided with a bent part 32 extending towards the deformed end 241 and a pressure strip 33 connected to the bent part 32 and capable of pressing against the deformed end 241. The bent part 32 allows the pressure strip 33 to extend above the deformed end 241, and the pressure strip 33 is long and extends along the length direction of the deformed end 241. The long pressure strip 33 can apply force to the deformed end 241 more evenly.

[0028] Below the large pressure frame 2, there is a clamping piece 4 that is open and closed. The clamping piece 4 is arranged vertically opposite to the front and rear fixed material pieces 24. A clamping cylinder 41 is installed on the large pressure frame 2. The clamping piece 4 is connected to the driving end of the clamping cylinder 41 and can be driven to move up and down. Thus, the clamping cylinder 41 can drive the clamping piece 4 to press against the lower end face of the front and rear fixed material pieces 24.

[0029] Furthermore, when the pressure plate 31 of the small pressure frame 3 is driven to press down on the garment, the deformation ends 241 of the front and rear fixed pieces 24 can be subjected to force and deform slightly downward, and press down tightly against the clamping piece 4, so that the pressure plate 31, the front and rear fixed pieces 24 and the clamping piece 4 can be pressed together more tightly and flatly, so that the clamping force on the pocket is more uniform, that is, the clamping effect on the garment pocket is improved, and the subsequent processing quality and stability of the pocket are guaranteed.

[0030] Meanwhile, the deformation setting of the deformable end 241 under force avoids affecting the stability of the installation of the front and rear fixed pieces 24 due to frequent pressure, thereby improving the reliability of the pocket processing.

[0031] There are two pressure plates 31, which are distributed in front and behind. The two pressure plates 31 correspond to the two front and rear fixed plates 24 respectively. At least one pressure plate 31 can be driven and move up and down relative to the small pressure frame 3. Preferably, in this embodiment, both pressure plates 31 can move up and down independently relative to the small pressure frame 3.

[0032] Specifically, the small pressure frame 3 is equipped with a cylinder that can drive the pressure plate 31 to move up and down. Thus, during the processing of the garment pocket, the pressure plate 31 can press down on the front and rear fixed pieces 24 to fix the garment pocket on the large pressure frame 2 and the front and rear fixed pieces 24. At this time, the front and rear fixed pieces 24 are not deformed by pressure, so that when folding the pocket, the folding knife can adhere to the front and rear fixed pieces 24 to fold the edge of the pocket, so as to ensure the folding effect of the pocket.

[0033] When the garment pocket needs to be clamped by the clip 4, the pressure plate 31 can be driven to move further downward, and the front and rear fixed pieces 24 can be slightly deformed downward and tightly attached to the clip 4 to improve the clamping effect on the pocket pocket.

[0034] The large pressure frame 2 is provided with a fixed plate 23 that can slide back and forth. The front and rear fixed material pieces 24 are fixedly installed on one side of the fixed plate 23. The fixed plate 23 drives the front and rear fixed material pieces 24 to move back and forth synchronously. The large pressure frame 2 is provided with a drive cylinder 21. The drive end of the drive cylinder 21 is connected to a drive plate 22 that can drive the fixed plate 23 to slide back and forth. The drive plate 22 is slidably disposed on the large pressure frame 2 and connects the fixed plate 23 and the drive end of the drive cylinder 21.

[0035] When the pocket needs to be folded, the front and rear fixed pieces 24 are driven to move closer to each other and provide a folding edge for the pocket folding operation, so that the pocket can be folded along the edges of the front and rear fixed pieces 24; after the pocket folding operation is completed, the front and rear fixed pieces 24 are driven to move away from each other to provide a sewing gap for the subsequent pocket sewing operation.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
