Description

Technical Field

[0001] The invention relates to valve bag processing equipment, in particular to a valve bag folding cold cutting and forming integrated machine. Background Art

[0002] Valve bags are a type of packaging bag that is fed from the top or bottom valve port and filled using special filling equipment. When the goods are filled, the contents will squeeze the valve port from the inside to achieve a sealing effect. The bags are neatly stacked and beautiful, and are environmentally friendly bags. Valve bags are mainly used to package edible powder, chemical powder, fertilizer, synthetic materials, explosives, grain, salt, minerals and other powdered or granular solid materials and flexible items.

[0003] The processing method commonly used in the valve bag forming machine on the market is not convenient for processing valve bag fabrics. Usually, a "7"-shaped groove is cut out at one end of the woven bag fabric at the first station, and then the end of the woven bag fabric with the "7"-shaped groove is folded at the second station, and finally sewing is performed to form. During the processing, the "7"-shaped groove needs to be cut out, and then the end of the woven bag fabric with the "7"-shaped groove is folded. The unique "7"-shaped groove will cause the processing to be complicated and inconvenient, which will affect the processing efficiency of the valve bag. The complicated processing method will also cause the equipment structure of the valve bag forming machine to be complicated, which is not convenient for the processing and manufacturing of the equipment. In view of the above defects, the present invention has made improvements. Summary of the invention

The opening mechanism 7 and the folding structure are arranged on both sides of the same side of the separation mechanism 6. The opening mechanism 7 includes an upper support plate 11 and a lower support plate 12 which are parallel to each other. The opening mechanism 7 can make the upper support plate 11 and the lower support plate 12 translate together and be inserted between the upper suction cup 9 and the lower suction cup 10. The folding mechanism 8 includes a folding plate 13 which can make the folding plate 13 translate and be inserted between the upper support plate 11 and the lower support plate 12. The cold cutting mechanism 3 includes an upper knife 14 and a lower knife 15 which are relatively and staggered. The cold cutting mechanism 3 can drive the upper knife 14 and the lower knife 15 to perform cold cutting.

When the bag opening is sucked open, the upper layer of fabric 16 of the woven bag is separated from the lower layer of fabric 16. The opening mechanism 7 and the folding mechanism 8 work simultaneously to fold the bag opening into a semi-finished product. The opening mechanism 7 drives the upper support plate 11 and the lower support plate 12 to translate together and insert them between the upper suction cup 9 and the lower suction cup 10.

The formed cloth 16 is then sent out through the circulating conveying mechanism 2, and the woven bag cloth 16 is first folded at the first station 4 by the folding mechanism, and then conveyed to the second station 5 by the circulating conveying mechanism 2 for cold cutting and shaping by the cold cutting mechanism 3. It can be seen that in the above processing method, it is not necessary to separately process the woven bag cloth 16 to cut a "7"-shaped groove. By changing the processing method, it is convenient to process the woven bag cloth 16 and improve the processing efficiency of the valve bag. It can also make the structure of the valve bag processing equipment simpler, which is convenient for the processing and manufacturing of the equipment. In specific implementation, the structure of the fabric 16 processed by the folding mechanism and then cold cutting by the cold cutting mechanism 3 is consistent with the structure of the fabric 16 processed by cutting a "7"-shaped groove in the traditional fabric 16 and then folding the fabric 16, which can facilitate further processing into a finished valve bag.
