Description

Technical Field

[0001] The utility model relates to the technical field of plastic woven bag conveying, in particular to a plastic woven bag conveying and pressing bag device. Background Art

[0002] Woven bags, also known as snakeskin bags, are a type of plastic bag used for packaging. Their raw materials are generally various chemical plastic materials such as polyethylene and polypropylene. During the processing of woven bags, the whole roll of woven bags is cut by a cutter to form a single woven bag with a predetermined length. Then, the woven bag needs to be transported from the cutting position to the position of the inner bag through a conveying device, and then the woven bag with the inner bag is transported to the position of sewing and sealing.

[0003] Generally, plastic woven bags are conveyed by a reciprocating conveying frame, and an air suction device is arranged on the conveying frame, the air suction device includes an air pump and a suction nozzle. The air pump works to make the suction nozzle suck the plastic woven bag, and then the conveying frame moves to convey the plastic woven bag. Since the suction force of the suction nozzle is limited, it is difficult for one suction nozzle to suck the entire plastic woven bag. Therefore, the friction generated by the contact between the plastic woven bag and the supporting surface of the frame during the conveying process may cause the plastic woven bag to separate from the suction nozzle. Therefore, it is necessary to increase the number of suction nozzles and line them up in a row in the length direction of the plastic woven bag. Generally, three suction nozzles are arranged to suck one plastic woven bag, which makes the volume of the entire suction device very large, which not only increases the production cost, but also occupies a large space.
