[0002] Woven bags, also known as snakeskin bags, are a type of plastic bag, mainly used for packaging. Its raw materials are generally various chemical plastic raw materials such as polyethylene (PE) and polypropylene (PP). Woven bags have good moisture resistance and durability, and are often used to package grains, flour, rice, sugar and other foods;

[0003] In the process of producing and processing woven bags, in order to display the brand logo or make it more beautiful, some words or patterns are usually printed on the outer surface of the woven bags. At present, in the process of printing the woven bags, an external conveying device is usually used to move the woven bags to be printed to the lower side of the surface printing device for woven bag production, and then the surface printing device for woven bag production sprays ink to print the pattern on the outer surface of the woven bag;

[0004] During the use of existing surface printing devices for woven bag production, some woven bags will have some wrinkles, and some dust and debris will usually adhere to the outer surface of the woven bag, which will affect the printing effect of the woven bag in the subsequent printing work. Some surface printing devices for woven bag production manually clean and flatten the woven bags before printing. Although this improves the printing quality, the operation is cumbersome and the workload of the personnel is relatively heavy. For this reason, we propose a surface printing device for woven bag production. Utility Model Content
