Description

Technical Field

[0001] The invention belongs to the technical field of textile machinery manufacturing, and relates to the improvement of a carding machine, in particular to a carding machine cover cleaning device, a carding machine and a cover cleaning method. Background Art

[0002] The carding machine is a crucial part of the cotton spinning process. Its previous process is the opening and cleaning machine, and the subsequent process is the drawing machine. It is mainly used to card pure cotton, chemical fiber and their blended fibers. The raw materials are fed from the cotton box, and after a series of mechanical actions, the curled cotton fibers are combed into a basically straight fiber state, and impurities are removed, and finally cotton strips are formed for subsequent spinning processes.

[0003] The cylinder-flat carding area is the core carding link of the carding machine. It is crucial to ensure the carding quality and meet the growing product quality standards. It is necessary to regularly remove the cotton wool and impurities accumulated on the flat card clothing. Therefore, an efficient flat cleaning system plays a key role in maintaining the cleanliness of the flat card clothing. The flat brush roller and the rotating flat plate are in a negative spacing, that is, the card clothing on the flat brush roller and the card clothing on the rotating flat plate are staggered, and the flat brush roller and the cleaning roller cooperate to clean the rotating flat plate. Existing carding machines generally adopt the following strategy: first, use the slowly rotating flat brush roller to peel off the short fibers and impurities on the rotating flat card clothing and make them adhere to the surface of the brush roller; then, use the fast rotating cleaning roller to remove these attachments from the brush roller surface and suck them into the dust filter system with the help of the suction port. This cycle ensures the continuous cleanliness of the brush roller, thereby continuously and effectively removing cotton wool and impurities on the flat plate.

[0004] However, in the actual production process, the cleaning roller often fails to effectively remove the cotton wool on the flat brush roller, resulting in an increasing amount of cotton wool accumulated on the brush roller surface and entangled on the surface of the flat brush roller and the cleaning roller, which in turn causes the cleaning roller in high-speed operation to be forced to stop due to external interference, and is unable to timely and effectively clean the rotating flat needle clothing, which has an adverse effect on the combing effect and also increases the working time of cleaning the flat needle clothing, flat brush roller and cleaning roller. In addition, the cotton wool and impurities accumulated on the surface of the flat brush roller not only increase the resistance of the rotating flat needle clothing, but also cause extrusion at the contact point between the two. Since the spacing between the two cannot be adjusted, it sometimes causes damage to the rotating flat needle clothing and the flat brush roller clothing. This situation in turn increases the number of cotton knots and cotton impurities, causing equipment failures, which directly interferes with production efficiency and product quality.

[0005] Therefore, the art urgently needs to design a carding machine cover plate cleaning device, a carding machine and a cover plate cleaning method to solve the problem that the cover plate brush roller and the cleaning roller are difficult to completely transfer cotton wool in the prior art, resulting in the cover plate brush roller being entangled and fire caused by serious entanglement, and at the same time solve the problem of needle clothing falling off caused by the small distance between the cover plate brush roller and the cleaning roller.
