Description
Technical Field
[0001] The utility model relates to the technical field of cotton carding machines, in particular to a tube changing device for cotton carding machines. Background Art
[0002] Carding machines are used to process cotton fibers and chemical fibers and are textile machinery. According to the spinning process, carding is an important process. The working principle of the carding machine is to open, comb and remove impurities from the cotton (fiber) rolls sent from the previous process or the oily cotton (chemical fiber) layer supplied by the cotton box, so that all the curled cotton loops become basically straight single fibers. In the process, the broken seeds, impurities and short fibers left over from the cotton cleaning process are removed, and then cotton strips of a certain specification are integrated and stored in the cotton tube for use in the drawing process.
[0003] The cotton slivers of the carding machine are evenly placed on the upper end of the cotton cylinder through guide wheels and coilers. After the cotton cylinder is full, the cotton cylinder is usually replaced by an automatic cylinder changing device. The automatic cylinder changing device pushes the idle cotton cylinder through a push rod, and the idle cotton cylinder pushes the cotton cylinder full of cotton slivers to push it out. During this period, the two cotton cylinders collide with each other, and the center of gravity of the cotton cylinder full of cotton slivers is biased upward, and there is a risk of tipping over when pushed. Therefore, we propose a cylinder changing device for a cotton carding machine. Utility Model Content

[0012] Furthermore, it further includes slopes. The slopes are respectively bolted to the left and right sides of the base. Semi-circular grooves are formed in the planes of the slopes at the upper ends of the base. The diameters of the semi-circular grooves are the same as the diameter of the rotating platform.
