Device and method for opening and conveying ordinary woven bags

Abstract

The invention belongs to the field of production of woven bags and in particular relates to a device and a method for opening and conveying ordinary plastic woven bags. The device comprises an unwinding device, a buffering and bag-conveying device and a conveying belt which are connected with one another in sequence, wherein a hot cutting device is arranged between the buffering and bag-conveying device and the conveying belt; the hot cutting device comprises an upper hot cutting device and a lower hot cutting device; an electric heating wire is arranged on the upper hot cutting device; two upper bag-opening suction boxes are arranged on two sides of the electric heating wire in a bilateral symmetry manner; two upper bag-twisting rollers are arranged on two sides of each upper bag-opening suction box in a bilateral symmetry manner; a cutter groove is formed in the lower hot cutting device and is located under the electric heating wire; a lower bag-opening suction box is arranged under each upper bag-opening suction box; a lower bag-twisting roller is arranged under each upper bag-twisting roller. According to the device and the method for opening and conveying the ordinary plastic woven bags, the problem that the openings of the ordinary hot-cut woven bags are liable to cling can be effectively solved; external bags can be completely opened, thereby establishing foundation and providing guarantee for automatically accommodating internal bags into the external bags subsequently.

Description

technical field [0001] The invention belongs to the field of woven bag production, in particular to a device and method for opening and transporting ordinary plastic woven bags (uncoated and composite woven bags). Background technique [0002] At present, there is a great demand for double-layer ordinary woven bags on the market, that is, ordinary woven bags on the outside and film-lined bags inside. However, the inner bags of this kind of ordinary woven bags are basically bagged manually. The cork sewing machine for woven bags is still blank. The main reason is that ordinary woven bags must be eagerly cut before the subsequent bagging process. However, the mouth of the bag after eager cutting is easy to stick. If you use the cold cutting method, the bag mouth will not stick after cold cutting, but it is easy to loose threads. Therefore, to solve the problem that the mouth of the woven bag that must be cut is easy to stick, a new bag opening method is proposed. method, this...

Problems solved by technology

[0003] In order to solve the problems in the prior art and solve the problem that the mouth of the ordinary woven bag is easy to stick after being eagerly cut, the present invention proposes a new automatic bag opening and conveying equipment and method for ordinary woven bags. In order to achieve this purpose, this The technical solution disclosed by the invention: an ordinary woven bag opening and conveying equipment, including an unwinding device, a buffer bag feeding device and a conveying belt connected in sequence, an eager cutting device is arranged between the buffer bag feeding device and the conveying belt, and the eager cutting device includes an upper There are two parts: the hot cutting device and the lower hot cutting device. The upper hot cutting device is equipped with electric heating wire or electric heating sheet or electric heating cutter. Two symmetrical upper opening suction boxes are arranged on both sides of the electric heating wire. There are two symmetrical upper bag rubbing rollers on the side, and a cutter slot on the lower hot cutting device. The cutter slot is located directly below the heating wire. There is a lower bag rubbing roller directly below the bag roller
