Woven packaging bag surface printing process

Abstract

The invention relates to a woven packaging bag surface printing process. The woven packaging bag surface printing process mainly includes the following steps of material preparation, printing operation, packaging operation and other multiple procedures. Used packaging bag printing and stacking equipment comprises a bottom plate, a conveying device, a printing device, a drying device and a stackingdevice. The problems that a, when woven packaging bags are printed traditionally, as the woven packaging bags are not positioned and clamped, the woven packaging bags can deviate, printed patterns are likely to be wrinkled, and the effect is not good; and b, the woven packaging bags cannot be stably stacked after the woven packaging bags are printed in the prior art, the woven packaging bags needto be manually collected and stacked, labor force is wasted, the woven packaging bags easily deviate in the conveying process, and the woven bags are easily wrinkled when stacked existing in existingwoven packaging bag printing and stacking can be solved, and the printing efficiency and effect of the woven packaging bags are improved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a surface printing process of a woven packaging bag. Background technique [0002] Woven packaging bags are widely used in the packaging of fertilizers, cement, chemical products, etc. The main production process is to use plastic raw materials to extrude film, cut, and unidirectionally stretch them into flat wires, and weave warp and weft to obtain products. They have high strength, Due to the characteristics of low water absorption and low density, the surface of the packaging bag generally needs to print the relevant information of the manufacturer or product, so the printing of the packaging bag is an essential step in the production process of the packaging bag. [0003] However, the following problems exist in the printing and stacking of existing woven packaging bags. a. When printing traditional woven packaging bags, because the woven packaging bags are not positioned an...

AI Technical Summary

Problems solved by technology

[0003] However, the following problems exist in the printing and stacking of existing woven packaging bags. a. When printing traditional woven packaging bags, because the woven packaging bags are not positioned and clamped, the woven packaging bags will be offset, making the printed pattern There may be wrinkles, and the effect is not very good; b. After the existing woven packaging bags are printed, the woven packaging bags cannot be stacked stably, and manual collection and stacking operations are required, which is a waste of labor. Offset occurs, and when the woven packaging bag is conveyed, air is carried in the woven bag, and the woven bag is easy to wrinkle when stacked, which improves the printing efficiency and effect of the woven packaging bag
