Description

Technical Field

[0001] The utility model relates to the technical field of cloth pre-shrinking machines, in particular to a cloth pre-shrinking machine for producing denim cloth. Background Art

[0002] Denim is a wear-resistant and fashionable clothing material. It can be used to make jeans, denim jackets and other denim clothing, and is very popular among young people. In the production process of denim, pre-shrinking is an important process. Since denim is easy to shrink, pre-shrinking denim before leaving the factory can greatly reduce the shrinkage rate of denim, so that users will not be unable to wear denim clothing due to excessive shrinkage.

[0003] According to the description in a steam box for pre-shrinking denim fabric disclosed on the patent website (authorization announcement number: CN 215051274U), "The utility model discloses a steam box for pre-shrinking denim fabric, including a box body, in which a feed roller, a discharge roller, a mesh conveyor belt assembly, a material blocking assembly and a plurality of steam nozzles are arranged; the surfaces at both ends of the box body are respectively provided with a feed port and a discharge port, the feed roller, the mesh conveyor belt assembly and the discharge roller are arranged in sequence along the material path of the denim fabric, and the feed roller, the mesh conveyor belt assembly and the discharge roller are all used to convey the denim fabric; the denim fabric forms wrinkles on the mesh conveyor belt assembly, the material blocking assembly is located above the mesh conveyor belt assembly, and the steam nozzle is arranged below the mesh conveyor belt assembly. The utility model can effectively reduce the waste of steam and water resources and improve the relaxation of the denim fabric."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, steam is sprayed out from the steam nozzle, passes through the mesh conveyor belt assembly, and acts on the denim fabric conveyed by the mesh conveyor belt assembly. The denim fabric is heated by the steam and becomes loose during the conveying process. In actual use, since the positions of the inlet and outlet rollers of the device are fixed, it is not possible to limit the use of raw materials of different thicknesses well, which may easily cause accidents such as slipping during the transmission process. At the same time, the steam nozzle of the device is fixed in position, which may easily cause dead corners for spraying and different temperatures of raw materials, affecting the processing effect. Therefore, it is necessary to improve a fabric preshrinking machine for denim fabric production to solve the above problems. Utility Model Content
