Description

Technical Field

[0001] The utility model relates to the technical field of bag opening processing, in particular to a replacement structure for a bag opening flanging clip of a bag opening machine. Background Art

[0002] In the garment processing process, the pocket opening machine is an indispensable auxiliary processing machine. It is mainly used to form pockets at specific positions of the garment to facilitate carrying small items such as mobile phones and wallets. The current practice is to first process the pocket opening and the pocket lip separately, and then sew the pocket lip to the pocket opening to complete the pocket opening.

[0003] During bag opening processing, the bag opening needs to be cut and folded. Specifically, the cut bag opening is folded into the sizing window of the inner and outer pressure frames of the sizing device using a folding knife to form a flange. The sizing window, also known as the processing window, consists of two sets of front and rear, or four sets of left and right, movable expansion plates. As the folding knife retracts, it is easy for the flap to be pulled back. Therefore, a clamping piece is required below the sizing window to press the edge of the sizing window upward. This clamping piece is generally made of manganese steel, also known as a manganese steel sheet. This clamping piece secures the bag opening flange and prevents the flap from being pulled back when the folding knife retracts.

[0004] The utility model patent with the patent number ZL202120799445.6 discloses a bag opening burr clamping device for a bag opening machine, which includes an external pressure frame for supporting the bottom of the fabric, a rectangular material fixing window for the bag opening to fold over, and an elastic clip with a fixed end and a clamping end provided at the bottom of the external pressure frame. The clamping end is pressed against the edge of the material fixing window by the elastic force of the clip itself, and its fixed end is fixed to the external pressure frame by screws. Pockets of different sizes require the replacement of the mold and clip of the material fixing window. However, in order to replace the clip, it is very inconvenient to unscrew the screws every time, and the screws often slip and get damaged, which seriously affects work efficiency and maintenance costs.

DETAILED DESCRIPTION

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0032] In the description of this specification, the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0033] Example 1:

[0034] refer to Figures 1 to 3As shown, this embodiment discloses a replacement structure for the bag opening flanging clip of a bag opening machine, comprising an external pressure frame 1 and a clip 2 arranged below the external pressure frame 1, a fixed cylinder 12 is installed on the external pressure frame 1, the fixed cylinder 12 and the clip 2 are distributed up and down on the upper and lower sides of the external pressure frame 1, an assembly hole 11 is opened on the external pressure frame 1, and a fixed end 201 corresponding to the position of the assembly hole 11 is provided on the clip 2, and the number of the assembly hole 11 and the fixed end 201 is two and they are distributed relatively up and down.

[0035] The output end of the fixed cylinder 12 is connected to the fixed end 201 through the assembly hole 11 and drives the clip 2 to be fixed and limited on the external pressure frame 1.

[0036] Specifically, the fixed end 201 is provided with a limit block 21 extending upward from the assembly hole 11, the upper end of the limit block 21 is higher than the plane of the external pressure frame 1, and the side wall of the limit block 21 is abutted with a push block 13 connected to the output end of the fixed cylinder 12. The fixed cylinder 12 is horizontally arranged on the external pressure frame 1, and the fixed cylinder 12 drives the push block 13 to move horizontally, and presses the limit block 21 through the push block 13 to limit the limit block 21 to the side wall of the assembly hole 11, and then fix the limit block 21 in the assembly hole 11 to achieve the installation and fixation of the clip 2.

[0037] When the clip 2 needs to be replaced, the fixed cylinder 12 is driven to move the push block 13 away from the limit block 21, thereby unlocking the clip 2 and replacing the limit block 21 and the clip 2 fixed on the clip 2 together, so that the clip 2 can be quickly replaced, thereby overcoming the defects of the existing screws being easily slipped and damaged when replacing the clip 2, improving the replacement efficiency of the clip 2 and reducing maintenance costs.

[0038] In order to improve the stability of the installation and use of the clip 2, an outward-protruding ridge 211 is provided on the side wall of the limit block 21. The ridge 211 is located on one end of the limit block 21 that extends upward from the assembly hole 11. When the limit block 21 abuts against the side wall of the assembly hole 11, the ridge 211 limits the downward displacement of the clip 2, thereby improving the reliability of the limit block 21 abutting and fixing in the assembly hole 11.

[0039] Example 2:
