Description

Technical Field

[0001] The utility model relates to the field of cloth processing, in particular to a cloth roll cutting device. Background Art

[0002] The water jet loom is a shuttleless loom that uses a jet of water to pull the weft yarn through the shed. The frictional traction of the water jet weft insertion on the weft yarn is greater than that of the air jet weft insertion, and the diffusion is small, which is suitable for the weft insertion of smooth-surfaced synthetic fibers, glass fibers and other filaments. At the same time, it can increase the conductivity of synthetic fibers and effectively overcome static electricity in weaving. In addition, the jet weft consumes less energy and has the lowest noise. Since the fabric is produced continuously, the fabric produced will be cut when it is wound into a roll.

[0003] For example, the patent with the authorization announcement number CN117800146A discloses a continuous production cutting device for textile products, including a base device, a power device is arranged in front of the base device, and a flattening device is arranged on one side of the power device;

[0004] In the above patent, after the cloth material stops on the processing table, the rubber roller rotates and moves downward from the highest point of the synchronous belt parallel to the processing table, pressing the cloth material through elastic force to flatten it, so as to improve the cutting accuracy; however, the disadvantage of the above patent is that the rubber roller is fixed on one side, so when the cloth contacts the rubber roller, the rubber roller away from the side of the synchronous belt may deflect, which will cause the cloth to shift and wrinkle.

[0005] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Utility Model Content
