Description

Technical Field

[0001] The utility model belongs to the technical field of woven bag color printers, and particularly relates to a woven bag color printer. Background Art

[0002] A woven bag color printer is a device specifically used for color printing on woven bags. It adopts advanced printing technology and can clearly print various delicate patterns and texts on woven bags. The operation is convenient and fast, enabling high-efficiency batch production. Its precise color control ensures bright and lasting printing effects, enhancing the beauty and added value of woven bags. After the woven bag color printing is completed, a winding drum is usually used to wind the woven bag. However, the current winding drum has a fixed width and cannot be adjusted, which brings great inconvenience. When facing wider woven bags, due to the width limitation of the winding drum, effective winding operations cannot be carried out. This not only limits the applicable range of the color printer but also requires the purchase of winding equipment of different specifications, increasing production costs. Moreover, in actual production, if orders for woven bags of different widths are encountered, the equipment may need to be frequently replaced, wasting a large amount of time and manpower and reducing production efficiency. When winding narrower woven bags, the wider spacing on both sides will result in poor winding effects. In this case, the woven bags are prone to looseness and unevenness during the winding process, affecting the appearance quality of the products. To solve this problem, we have developed a woven bag color printer. Content of the Utility Model
