Description

TECHNICAL FIELD

[0001] The present application relates to the field of sewing machines, in particular to an automatic bag attaching machine for processing clothes and the like. BACKGROUND

[0002] The current bag attaching machine can realize automatic sewing processing of clothes with bags, such as shirts, sweaters, jeans and the like. Some of the bag attaching machines fold and iron the bag piece and then place it on the cloth piece on the feeding workbench. Some of the bag attaching machines are provided with an automatic folding device above the cloth piece feeding workbench. In this way, the operator only needs to place the cloth piece on the feeding workbench and then place the bag piece on the bag-shaped plate. The automatic folding device folds the bag piece on the bag-shaped plate and then presses it on the cloth piece. Subsequently, the automatic folding device is reset upward. The feeding pressing plate is moved to the feeding workbench to press the folded bag piece and the cloth piece together. The bag-shaped plate is reset backward. In this way, the feeding pressing plate can send the folded bag piece and the cloth piece together to the sewing machine head for sewing processing. For some high requirements or situations where it is desired that the bag piece and the cloth piece are attached neatly and closely (especially for the processing of jeans), after the cloth piece is placed on the feeding workbench, the two sides of the cloth piece need to be slightly pushed to the middle by using the two side pushing mechanisms. The structure of the pushing mechanism is complex, occupies the space above the workbench, and depends on the pressing of the two sides of the cloth piece to push inward. The control precision of the deformation of the middle part of the cloth piece is not ideal, and it is difficult to meet the order processing requirements of high consistency of product processing.

[0003] And, some trousers bag / clothes bag inside need to add gasket, for example, CN110306301A discloses a full-automatic cold folding bagging machine, which comprises a workbench assembly, a sewing assembly, a folding device, a feeding device and a feeding and sewing driving device, and further comprises a gasket feeding device, which comprises a feeding disc assembly, a conveying assembly, a shearing assembly, a feeding assembly and a connecting seat assembly. During work, the gasket tape is first unwound, passes through the dynamic cutter and the fixed cutter of the shearing assembly to the lower side of the pressing plate of the pressing assembly, and then the piston rod of the cylinder of the feeding lifting driving device of the feeding assembly is retracted downward, so that the lifting seat is lowered, and the gasket adsorption panel is lowered to the upper surface thereof below the cutter edge of the fixed cutter of the shearing assembly. Then, the piston rod of the cylinder of the feeding front and rear driving device is extended rearward, so that the rear side of the gasket adsorption panel of the air suction box assembly abuts against the front side of the guide portion of the dynamic cutter, and the corresponding part of the gasket adsorption panel of the air suction box assembly is located below the pressing plate of the pressing assembly, and the gasket tape is located between the gasket adsorption panel and the pressing plate. The piston rod of the pressing driving cylinder of the pressing assembly is extended downward, and the pressing plate drives the gasket tape to be pressed and fixed on the gasket adsorption panel. Then, the piston rod of the driving cylinder of the shearing assembly is extended downward, and the dynamic cutter is driven to move downward, so that the gasket tape is cut off together with the fixed cutter, and the two pieces of gasket are located on the gasket adsorption panel. Then, the air suction of the air suction fan forms negative pressure on the gasket corresponding part of the gasket adsorption panel, and the gasket is adsorbed and fixed on the gasket adsorption panel. Then, the piston rod of the pressing driving cylinder of the pressing assembly is retracted upward, and the pressing plate is lifted. Finally, the piston rod of the cylinder of the feeding front and rear driving device is retracted forward, and the piston rod of the cylinder of the feeding lifting driving device is extended upward, so that the gasket adsorption panel is located in the gasket feeding hole of the workbench plate, and the upper surface of the gasket adsorption panel is flush with the upper surface of the workbench plate, so that the two pieces of gasket are sent to the height position of the upper surface of the workbench plate, and the feeding of the gasket is completed. Obviously, the structure of the gasket feeding device is relatively complex, and the overall action steps of the gasket feeding device are more, which is not conducive to the further improvement of production efficiency.

[0061] As Figures 12 to 1 4 shows another specific structure of the bag vacuum suction positioning device, which has the same basic structure as the bag vacuum suction positioning device shown in Figures 7 to 11 The main difference is that the structure of the vacuum suction plate is different. Specifically:

[0062] The vacuum suction plate comprises a second vacuum seat B411 and a cover plate B412 arranged on the top of the second vacuum seat B411. Similarly, the cover plate B412 can be detachably mounted on the top of the second vacuum seat B411. The second vacuum seat B411 is provided with a second cavity B413.
