[0002] In the process of garment processing, a bag opening machine is an essential auxiliary processing machine. The conventional method is to process the bag mouth separately; the processing process of the bag mouth requires cutting, folding the bag, and sewing the bag mouth position of the garment; cutting means cutting cracks at both ends of the upper opening of the bag mouth in a "Y" shape; folding the bag means turning the cut bag mouth inward to form a turned edge.

[0065] Working principle:

[0066] When the bag opening machine works, the staff places the garment fabric on the large pressing frame 24. The large pressing frame 24 supports the garment fabric, and the small pressing frame 25 moves towards the large pressing frame 24 to press and fix the garment fabric;

[0067] Since the large pressing frame 24 is located below the laser mechanism 6 at this time, the control cylinder 62 controls the laser tube 61 to move towards the direction close to the large pressing frame 24 to the processing position. At this time, the output end of the laser tube 61 can perform laser bag opening on the garment fabric; control the large pressing frame 24 to move along the path of laser bag opening, and the laser tube 61 works, so that the laser tube 61 performs laser bag opening on the garment fabric;

[0068] After the bag opening is completed, the control cylinder 62 controls the laser tube 61 to move away from the large pressing frame 24 to evacuate. At this time, the folding bag mechanism 5 is located above the pressing mechanism 2, and the movement of the large pressing frame 24 is controlled to make the folding bag assembly 55 correspond to the bag mouth on the garment fabric;

[0069] Control the folding bag assembly 55 to move towards the direction close to the large pressing frame 24 to the processing position. The folding bag assembly 55 pushes the cutting edge of the bag mouth downward to make it tilt downward, completing the folding bag action;

[0070] After the folding bag action is completed, the pressing mechanism 2 transports the garment fabric to the next working station for operation.

[0071] It should be noted that since the bag folding mechanism 5 and the laser mechanism 6 are both located at the same position as the initial position of the press-fitting mechanism 2, the transportation steps of the press-fitting mechanism 2 for transporting the garment fabric to the bag folding mechanism 5 and the laser mechanism 6 are streamlined, greatly shortening the working path and improving the transportation efficiency and production efficiency.
