Description

Technical Field

[0001] The utility model relates to the technical field of cloth cutting machines, and more specifically, to a limiting structure for a cloth cutting machine. Background Art

[0002] A cloth cutting machine is a mechanical device specially used for cutting cloth, leather and other items. Through the use of a cloth cutting machine, various fabrics can be cut efficiently and accurately, reducing the difficulty and labor intensity of manual operation. It is an indispensable and important tool in modern industrial production.

[0003] When the cloth cutting machine is cutting, in order to ensure the cutting accuracy, the cloth needs to be limited to prevent the cloth from moving or offsetting during the cutting process. By limiting the position, it can be ensured that the tool accurately cuts the cloth along the predetermined path, thereby achieving the expected cutting effect. More importantly, during the cutting process, if the cloth moves or offsets, the position of the cloth needs to be readjusted, which wastes a lot of time and manpower. By limiting the cloth, this situation can be avoided, thereby improving production efficiency.

[0004] For example, Chinese patent application number: CN202320004663.5 "A limiting component and cloth cutting machine". This cloth cutting machine allows the lower end of the limiting plate to press cloths of different thicknesses and allows the limiting plate to limit cloths at different positions on the table. However, before cutting the cloth, it is more important to ensure the flatness of the cloth. If wrinkles occur on the cloth, the cutting effect will be poor. Therefore, the staff needs to spend a lot of time to smooth the surface of the cloth before limiting it, which is time-consuming and labor-intensive, so it needs to be improved and optimized.

A moving block 18 is sleeved on the outer wall of the guide rod 17, and a second tensioning roller 20 is rotatably installed between the front and rear groups of moving blocks 18.

[0029] When the cloth 6 needs to be cut, the staff first pulls out one end of the cloth from the cloth winding roller, and passes it through the top of the first tensioning roller 15, the bottom of the second tensioning roller 20 and the top of the conveying roller 13 in sequence, and finally places the cloth 6 on the top of the base 1. At this time, the staff starts the cylinder 12, and the operation of the cylinder 12 presses the moving frame 9 downward along the limit groove 10.
