Description

Technical Field

[0001] The utility model relates to the technical field of bag opening processing accessories, in particular to a bag opening flanging clip quick die changing structure for 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. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a quick die-changing structure for a bag opening flanging clip of a bag opening machine, which can quickly fix and disassemble the clip to achieve rapid replacement.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A quick die-changing structure for a bag opening flanging clip of a bag opening machine comprises an external pressure frame of the bag opening machine and a manganese steel sheet with a fixed arm, wherein the manganese steel sheet is located at the bottom of the external pressure frame, an assembly hole is provided on the external pressure frame, a locking block extending from the assembly hole is provided on the fixed arm, a quick latch connected to a manganese steel sheet fixing cylinder is provided on the external pressure frame, and a socket for inserting the quick latch is provided on the locking block.

[0008] Preferably, a spring is sleeved on the piston rod of the manganese steel sheet fixing cylinder.

[0009] Preferably, the fixed arm of the manganese steel sheet is locked and fixed between the locking block and the clip support plate, and the locking block is located at the top.

[0010] Preferably, the external pressure frame is provided with a push-up cylinder and a push-up hole, and the piston rod of the push-up cylinder acts on the fixed arm through the push-up hole.

[0011] Preferably, the manganese steel sheet fixing cylinder is installed on the outer pressure frame via a fixing block.

[0012] Preferably, the quick latch and the socket are in corresponding conical shapes.

[0013] The beneficial effects of the utility model are:

[0014] 1. When the manganese steel sheet is at the bottom of the outer eye socket, the locking block will extend from the assembly hole. The cylinder fixing the manganese steel sheet pushes the quick latch to insert into the socket of the locking block to complete the locking. Otherwise, the manganese steel sheet is unlocked and falls out of the assembly hole, which is convenient for replacing the manganese steel sheet. With the help of pneumatic control, one-button pick-up and placement is realized, which overcomes the defect of screw slippage and damage in the existing structure, improves work efficiency and reduces maintenance costs.

[0015] 2. The spring on the piston rod will support the quick latch to be inserted into the socket. After the manganese steel sheet fixes the cylinder, the manganese steel sheet will remain locked, thereby improving the stability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
