Abstract

The invention provides a bag opening process of a full-automatic bag opening machine, which comprises the following steps of firstly placing a piece of cloth for opening a bag on a substrate below a laser cutting mechanism, placing a piece of cloth for sewing the bag on a supporting plate, cutting a Y-shaped opening by the laser cutting mechanism according to the size of the bag, secondly, driving the cloth to move below a slotting cutter mechanism by the substrate, opening a fixed cutter to form a fixed material opening, extending front and rear material pulling cutters, inserting the corresponding cloth into a slot corresponding to the descending of a front inserting plate and a rear inserting plate of the front and rear material pulling cutters, and sequentially retracting the inserting plate and the front and rear material pulling cutters. The four sizing knives are firstly molded into a sizing opening larger than the size of the pocket, then the material pulling knives pull the cloth open, then the positioning strip with the shape consistent with that of the pocket is moved to the center of the sizing opening, then the four sizing knives extend out to drive the cloth to prop against the positioning strip to form the pocket with the standard size, and then the pocket is pressed down by the external pressing frame and simultaneously withdrawn from the sizing knives, so that the pocket is firmly pressed on the supporting plate by the external pressing frame.

Description

Bag opening process of full-automatic bag opening machine Technical Field The invention relates to the technical field of clothing processing, in particular to a bag opening process of a full-automatic bag opening machine. Background In the clothing processing process, the bag opening machine is an indispensable auxiliary processing machine and is mainly used for forming a pocket at a specific position of clothing, so that small articles such as mobile phones and purses can be conveniently carried. The conventional practice is to process the pocket mouth and the pocket lip separately and then to sew the pocket lip to the pocket mouth to finish the opening of the pocket. The processing process of the pocket mouth needs to cut, fold the pocket, shape and sew the pocket lip of the clothing, the cutting is to cut the slit that both ends of the pocket mouth are Y-shaped, the pocket mouth of which is to be cut is folded inwards to form a flanging, the pocket lip shaping is to place the pocket lip on the flanging, and finally the sewing is performed. The principle of the clothing bag opening machine capable of automatically completing the cutting, bag folding, bag lip shaping and sewing procedures is that a laser cutting machine cuts cloth into slits with Y-shaped two ends, then the cloth is folded into a bag shape and then is sewn, then a piece of base cloth is newly placed on a workbench surface on one side, then the bag is moved to the position above the newly placed base cloth, and the bag is moved to the sewing area to sew the other three sides by pressing the base cloth, so that the bag manufacturing is completed. At present, in the pocket folding process after the laser cutting is finished, firstly, a fixed material knife stretches out to form a fixed material opening (pocket shape), then a material pulling knife stretches out to the fixed material opening, a material inserting knife inserts the cloth into a slot of the material pulling knife, then the material pulling knife pulls out the cloth to the edge to form a pocket shape, and finally, the fixed material knife is retracted to complete the pocket folding process. However, after the fixed material knife is retracted, the cloth at the pocket lacks the constraint of the fixed material knife, so that the pocket is easy to retract inwards, the pocket is deformed, and the shape of the pocket is influenced after sewing. Disclosure of Invention (One) solving the technical problems Aiming at the defects of the prior art, the invention provides a bag opening process of a full-automatic bag opening machine, and solves the problems in the prior art. (II) technical scheme The bag opening process of the full-automatic bag opening machine is realized by adopting the following technical scheme that the bag opening machine comprises a frame with a workbench, three stations are transversely arranged on the frame corresponding to the workbench, the three stations are respectively a laser cutting mechanism, a sewing mechanism and a slotting mechanism, a substrate capable of transversely moving along the three stations is arranged on the workbench, the substrate drives cloth to transversely move on the workbench through a transverse moving mechanism, a pressing mechanism is arranged on the substrate and is used for pressing the cloth on the substrate, a supporting plate clamp used for driving a supporting plate to move is arranged on the frame and is used for supporting the cloth of a seam pocket, and a material pulling mechanism and a material fixing mechanism are arranged on the substrate, and the bag opening process comprises the following steps: Placing a piece of cloth for opening the pocket on a substrate below a laser cutting mechanism, placing a piece of cloth for sewing the pocket on a supporting plate, then descending an external pressing frame to a coordinate I to press the cloth, and cutting a Y-shaped opening by the laser cutting mechanism according to the pocket size; step two, lifting the substrate, driving the cloth to move below the slotting mechanism, opening a fixed material cutter to form a fixed material opening, extending front and rear material pulling cutters, inserting corresponding cloth into the slot corresponding to the descending of the front and rear material pulling cutters, and sequentially retracting the plugboard and the front and rear material pulling cutters; After the slotting mechanism is reset, the positioning strip moves to the center of the fixed material port, the substrate is pressed down onto the supporting plate, then the four fixed material blades extend out to push the edge of the cloth pocket onto the positioning strip so as to enable the fixed material port to be reduced, the external pressing frame is pressed down to a second coordinate, then the four fixed material blades are opened to enlarge the fixed material port, and the external pressing frame is pressed down to a third coordinate; Fourthly, clamping the supporting
