Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cloth folding and cutting, in particular to a large cloth folding and cutting device and an operation method thereof. BACKGROUND

[0002] With the continuous growth of living supplies, people use more and more cloth textiles, such as curtains, bed sheets, bedclothes, pillowcases, and other home textile products, clothes, hats, and other living supplies. People will cut the woven cloth to the required size, and then go through different sewing processes to make the required living supplies. In the traditional cloth cutting, it is manually done, first taking a ruler to measure the required size, then cutting it down with scissors, and then folding it into a state that can be packed and transported. If large-size cloth is encountered, multiple people need to work together to cut and fold the cloth one by one, which often causes cutting and folding deviation, affecting the quality of the cloth and subsequent processing. Later, cloth cutting and folding devices appear on the market, but such devices often exist independently and only cut or fold. If cutting and folding are combined together, the process will be complicated and time-consuming, and the cutting cloth needs to be manually or mechanically folded into the folding machine, which can only operate one piece of cloth at a time. If the cutting is too fast, there will be cutting backlog, and vice versa. This way is time-consuming and labor-intensive, and cannot be operated in large quantities. In order to facilitate subsequent processing, the edges of the cloth produced by the textile factory will have burrs or burrs, which need to be trimmed to ensure the edge is complete and free of burrs. However, the traditional trimming device is independent and uses a pressure roller to correct and smooth the edge of the cloth, and then a cutting knife is used to cut the edge. If the pressure roller fails, the trimming will be off, affecting the subsequent processing of the cloth, and the cost is high.
