Abstract
Description
Technical Field
[0001] The present application relates to the technical field of textile machinery, and in particular to a cotton opener for cellulose production. Background Art
[0002] When the raw cotton is transported to the textile factory, it is packed into tight, square bales. The bales need to be broken down into small cotton pieces, and then a cotton opener is used to loosen the small pieces and remove impurities in preparation for the subsequent textile process.
[0003] The existing cotton opener includes a shell body, which is provided with a cotton inlet, a cotton outlet and a miscellaneous outlet. A roller is rotatably connected inside the shell body, and a plurality of clappers are connected to the circumferential side walls of the roller. A blower for blowing air into the shell body and toward the cotton outlet is connected to one side of the shell body. A filter is fixedly connected below the roller, and the filter is located above the miscellaneous outlet. When the equipment is used, small cotton pieces are put into the shell body from the cotton inlet, and the roller drives the clapper to rotate, and the clapper beats the small cotton pieces, thereby loosening the small cotton pieces. Under the blowing of the blower, the loosened cotton wool is moved out of the shell body from the cotton outlet, and at the same time, the magazines are moved out of the shell body from the miscellaneous outlet through the filter, thereby completing the loosening of the small cotton pieces.
[0004] With regard to the above-mentioned related technologies, after the cotton block is loosened, cotton wool is likely to remain on the rollers, clappers and filter nets, and impurities are likely to exist on the filter net. In order to reduce the impact on the next use of the cotton opener, the impurities or cotton wool on the rollers, clappers and filter nets in the shell need to be cleaned. However, the internal space of the shell is small, and cleaning is time-consuming and laborious, resulting in the defect that the cotton opener is inconvenient to clean. Utility Model Content
