Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to an automatic unwinding, conveying and feeding device for printing cloth. Background Art

[0002] Printing is a process of high-temperature printing and dyeing of grey cloth printed paper. It was very popular in the Tang and Song dynasties and reached its peak in the Ming and Qing dynasties. It was once deeply loved by people and was used as a must-have item for dowry bedding and clothes. Before processing, printing usually requires the use of automatic unwinding equipment to automatically transport the prints to the processing equipment;

[0003] The existing automatic unwinding and conveying device for printing usually uses an automatic unwinding device to automatically convey the printed material to the processing equipment along a set conveying route. However, in actual use, we found that each time the staff installs the printed fabric roller, they need to manually pull the head end of the fabric on the fabric roller onto the conveying mechanism. This manual pulling of the fabric requires a lot of physical strength and is easy to cause damage to the fabric. At the same time, during the automatic unwinding process, the staff needs to always keep an eye on the unwinding status of the fabric roller so as to replace the new fabric roller in time. Therefore, how to solve this problem is what we need to consider. Utility Model Content
