Description

Technical Field

[0001] The utility model relates to the technical field of looms, in particular to a cutting device for a loom. Background Art

[0002] Looms, also known as spinning machines, weaving machines, cotton spinning machines, etc., were all driven by manpower in the early days. With the continuous development of science and technology, the types of looms have become more diverse. After the looms have woven the cloth, they need to be cut and packaged through a cutting device.

[0003] In the Chinese utility model patent with authorization announcement number CN215441151U, a cutting device for a loom is disclosed, including a base plate, the base plate is a rectangular block, and an electric telescopic rod is installed at each of the four corners of the top of the base plate. The output end of the electric telescopic rod is fixedly connected to a fixed plate, and the fixed plate is located above the base plate. The telescopic direction of the electric telescopic rod is a vertical direction. A slider is horizontally slid at the bottom of the fixed plate, and a cutting knife is threadedly connected to the bottom of the slider. A groove for limiting the deflection of the cutting knife is provided on the base plate, and the groove is gap-matched with the cutting knife. A telescopic spring is fixedly connected to the bottom of the fixed plate.

[0004] The above patent compresses the cloth by a pressing plate to avoid the problem of the cutting angle of the cloth being deflected during the cutting process; however, when the patent cuts the cloth, its cutting knife cuts vertically at the side of the cloth.
