A woven bag making method and a woven bag making device using the method

Abstract

The invention relates to a technology of making woven bags from rolled woven bag tubular materials, in particular to a woven bag making method and a woven bag making device using the same. According to the woven bag making method, two layers of a woven bag tubular material to be cut are separated from each other at first before woven bags are cut off; if the method is used for cutting off the woven bags, notches of the cut woven bags are clear, and adhesion of the notches of the two layers is avoided; the woven bag making method is used for the woven bag making device, an opening device is arranged at the position of a woven bag cutting device, and the woven bags are cut off by an electric resistance wire under the condition that two layers of the woven bags are separated; and if the woven bag making device is used for making the woven bags, adhesion of the two layers at openings of the woven bags due to fusion of woven bag materials during hot cutting can be avoided, and therefore, the woven bags can be opened automatically when the woven bags are used in packing equipment in the later period.

Description

technical field [0001] The present invention relates to the technology of making woven bags from roll-packed woven bags, in particular to a woven bag making method and a woven bag making device using the method. The woven bag making method is performed before cutting the woven bag. First, separate the two layers of the woven bag material to be cut, and use this method to cut the woven bag so that the cut of the cut woven bag is clear without causing adhesion between the two layers of cuts. The woven bag making device is applied The woven bag making method is described. An opening device is arranged at the woven bag cutting device, and the woven bag is cut with a resistance wire in the state where the two layers of the woven bag are separated. Using the woven bag making device to make a woven bag can avoid At the opening of the woven bag, due to the melting of the material of the woven bag during the hot cutting, the two layers are bonded, which is convenient for the later pack...

AI Technical Summary

Problems solved by technology

[0002] The woven bag making equipment is relatively mature equipment, but since the woven bag is generally cut by thermal cutting, the cut woven bag will have different degrees of bonding at its opening end, which is not conducive to automatic packaging of materials with woven bags. Open the mouth of the woven bag. Therefore, it is generally necessary to manually open the bonded bag mouth during the bag making process or before using the woven bag to pack the material, which is inconvenient to use.

[0003] On the packaging equipment that uses woven bags as packaging materials, if woven bags with incisions and sticking are supplied to the packaging equipment, it is difficult for the packaging equipment to automatically open the mouth of the sticking woven bags; on the other hand, generally prepared woven bags are packaged in rolls It takes manpower and time to open a roll of woven bags and place them neatly in a stack. If they are not neatly arranged, it will also increase the automatic bag removal device on the packaging equipment when it is used on the packaging equipment. Difficulty in bagging, easy to cause bag failure
