Ordinary woven bag bag opening, conveying equipment and method

Abstract

The invention belongs to the field of woven bag production, and is specifically a kind of equipment and method that can be used for opening and conveying ordinary plastic woven bags, including an unwinding device, a buffer bag feeding device and a conveyor belt connected in sequence, and the buffer bag feeding device There is a hot cutting device between the conveyor belt and the hot cutting device. The hot cutting device includes two parts: the upper hot cutting device and the lower hot cutting device. The two sides of the bag opening suction box are equipped with two symmetrical upper rubbing rollers, and the lower hot cutting device is equipped with a cutter groove, which is located directly below the heating wire. Bag suction box, the lower rubbing roller is installed directly below the upper rubbing roller, which can effectively solve the problem that the pocket mouth of ordinary woven bags is easy to stick after eagerly cutting, and promotes 100% opening of the outer bag, automatically inserting the inner bag for the following The process inside the outer bag lays the foundation and provides a guarantee.

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
