Description

Technical Field

[0001] The invention relates to the technical field of garment processing, in particular to a true pocket sewing process of a laser bag opening machine. Background Art

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

[0003] The pocket opening processing process requires cutting, folding, lip shaping and sewing of the pocket opening of the garment. Cutting is to open a "Y"-shaped crack or an "I"-shaped crack at both ends of the pocket opening. Folding is to fold the cut pocket opening inward to form a flange. Lip shaping is to place the bag lip on the flange, and finally sewing is performed.

[0004] However, the current pressing frame has four sets of dosing knives and pulling knives, such as an automatic true pocket manufacturing machine with Chinese patent publication number CN221167014U. Since the four sets of dosing knives and pulling knives require four sets of cylinders and connecting rods, a larger installation space is required on the substrate, resulting in that only the size of the through groove can be compressed on substrates of the same size, resulting in the size of the manufactured pockets being limited; secondly, providing more sets of dosing knives and pulling knives will increase the weight of the substrate away from the load-bearing end, causing the far end of the substrate without a support point to sink and deform. Because the substrate will constantly move and contact with the work surface during use, the sinking substrate will seriously affect its use.

[0005] Therefore, how to reduce the number of the material cutting knives and the material pulling knives while completing the bag folding and sewing processes has become the problem that needs to be solved in this case. Based on this, this case was born. Summary of the invention

[0060] Two groups of inserting knife cylinders 78 are arranged on the lifting frame 75, and are used to drive two groups of front and rear inserting knives 76 to rise and fall respectively. The two front and rear inserting knives 76 correspond to the slots on the outer pulling knife 51 and the inner pulling knife 52 respectively, and can be inserted into the slots.

[0061] Two sets of material folding drive components 79 are arranged on the lifting frame 75, and are used to drive two sets of left and right material folding plates 77 to achieve lateral and vertical displacement. The two sets of left and right material folding plates 77 are located on both sides of the two sets of front and rear inserting knives 76. The material folding drive component 79 comprises a lateral cylinder 791, a lateral plate 792, and a vertical cylinder 793.

Then, the laser cutting mechanism 12 cuts the pocket cloth 14 according to the size of the pocket so that both ends are "Y"-shaped openings or "I"-shaped openings. At this time, the folding mechanism 7 is on standby beside the laser cutting mechanism 12.

[0073] Step 2: The base plate 1 is raised, and the base plate 1 drives the cloth to move to the bottom of the folding mechanism 7 and pauses briefly;

[0074] Step 3: The base plate 1 and the folding mechanism 7 are synchronously moved horizontally toward the bag stacking area. During the horizontal movement:

[0075] Action a: the driving component pushes the plastic plate 61 downwards to form a gap between the plastic plate 61 and the substrate 1 for pulling materials;

[0076] Action b, the folding mechanism 7 and the material setting component 4 and the material pulling component 5 in the base plate 1 perform a bag folding action on the pocket; specifically, the front and rear inserting knives 76 of the folding mechanism 7 insert the cut pocket fabric into the outer material pulling knife and the inner material pulling knife 52; then the outer material pulling knife and the inner material pulling knife 52 pull the fabrics on the front and rear sides outwards and shape them on the outer material setting knife 41 and the inner material setting knife 42; then, the vertical cylinder 793 drives the left and right folding plates 77 to descend, and the horizontal section 773 presses down the fabrics on the left and right sides of the pocket for a distance, and then the horizontal cylinder 791 drives the left and right folding plates 77 to move laterally outwards, so that the ends of the horizontal section 773 press against the fabrics on the left and right sides to fold over;

[0077] Action c, the driving component resets the plastic plate 61 upward, and uses the plastic plate 61 to press the four edges of the folded pocket;

[0078] Step 4: the base plate 1 is moved horizontally to the bag stacking area; the base plate 1 is lowered and connected to the vertical hole 84 on the bag plate 81 through the vertical positioning column 89, and then the base plate 1 and the bag plate 81 are moved horizontally to the sewing area together by the base plate moving mechanism;

[0079] Step 5: Fig.13 As shown, the sewing mechanism 13 sews the pocket cloth 14 and the first cloth 15 along the two sides and the bottom of the pocket, a total of three sides; at the same time, the pocket cloth plate conveying mechanism conveys the second pocket cloth plate 81 to the bag stacking area, and resets it after being placed, and the worker places the second cloth 16 on the second pocket cloth plate 81;

[0080] Step 6: After sewing is completed, the base plate 1 drives the pocket cloth plate 81 to move under the laser cutting mechanism 12, and then the base plate 1 rises to make the vertical positioning column 89 disengage from the vertical hole 84, and puts down the pocket cloth plate 81, and the pocket cloth plate 81 is grabbed by the pocket cloth plate conveying mechanism and moved to the rear to stand by;
