Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile processing equipment, and particularly relates to a bag opening machine for textiles. BACKGROUND

[0002] In the process of garment processing, the bag opening machine is an indispensable auxiliary processing machine, which is mainly used for forming a pocket at a specific position of a garment to facilitate carrying small items such as a mobile phone and a wallet.

[0003] The laser bag opening machine mainly consists of five mechanisms: a sewing mechanism, a feeding mechanism, a plate feeding mechanism, a cutting mechanism and a folding mechanism. The working process of the existing laser bag opening machine is as follows: a worker first places the cloth on the cloth supporting plate of the feeding mechanism, and the worker places the pocket on the circulating plate of the plate feeding mechanism; the cloth is pressed by the transfer feeding part, the cutting mechanism cuts on the cloth, the four edges of the cut are folded inward to form a flange by the folding part, and the feeding mechanism moves the cloth with the flange to the upper side of the circulating plate, and the pocket and the cloth are clamped together and moved to the sewing part for sewing.

[0004] The folding mechanism of the existing laser bag opening machine is arranged on the feeding mechanism and moves synchronously with the cloth supporting plate. The entire folding mechanism is installed above the cloth supporting plate and needs to move synchronously with the cloth supporting plate. Since the folding mechanism is very heavy, and it needs to be folded while moving, the moving speed of the feeding mechanism is limited, resulting in a very low overall processing efficiency of the cloth. In order to reduce the weight of the folding mechanism, the two long folding knives and the two short folding knives on the folding mechanism are driven to move by the air cylinder. This driving mode will result in low moving precision of the long folding knives and the short folding knives, resulting in inaccurate folding of the cloth opening.

[0005] The plate feeding mechanism of the existing laser bag opening machine generally includes a circulating plate and a driving mechanism for driving the circulating plate to move, and the driving mechanism includes two groups of straight line modules perpendicular to each other in direction, and the two straight line modules can drive the circulating plate to move back and forth along the X direction and the Y direction. When the folding work is completed, the feeding device will move to the upper side of the circulating plate, and then the circulating plate will move synchronously with the cloth supporting plate, so the circulating plate does not need a separate straight line module to drive it to move back and forth along the X direction. The design of this plate feeding mechanism increases a large number of components, increases the production cost and installation process of the equipment. SUMMARY
