Cotton pushing device for full-automatic cotton chopping machine

Abstract

The invention provides a cotton pushing device for a full-automatic cotton chopping machine. A central shaft of the cotton chopping machine is arranged on one side of a cotton chopping roller rotary shaft bracket; one cotton chopping roller rotary shaft bracket is arranged on each of the left and right sides of a cotton chopping roller of the cotton chopping machine; crank connecting rod mechanism mounting brackets are arranged on the front sides of the two cotton chopping roller rotary shaft brackets; a rotary shaft of an upper crank of a crank connecting rod mechanism is connected with the outer sides of the crank connecting rod mechanism mounting brackets and a rotary shaft of a driving gear of a gear mechanism; the lower end of two lower connecting rods of the crank connecting rod mechanism are in contact with the upper side of a cotton pushing plate; the cotton pushing plate is connected with a cotton chopping roller through a pair of compression springs; and a composite groove wheel and the gear mechanism are arranged on one side, close to the center, of a roller blade of the cotton chopping roller. By improving an existing cotton pushing device of the cotton chopping machine, accurate positioning and movement of a cotton pushing mechanism and the roller can be smoothly realized, so that the cotton chopping quality of the cotton chopping machine is indirectly improved.

Description

technical field [0001] The invention relates to the field of silk spinning equipment, in particular to a cotton pushing device for a fully automatic cotton cutting machine. Background technique [0002] Cotton cutting machine is used to process cotton fiber and chemical fiber, which belongs to textile machinery. According to the spinning process, cotton cutting is an important process. The front process of the cotton cutting machine is the combined opening and cleaning machine, and the subsequent process is the drawing frame (carding process) or coiler (combing process). The working principle of the cotton cutting machine is to loosen, comb and remove the cotton (fiber) strips sent by the previous process or the oil cotton (chemical fiber) layer supplied by the cotton box, so that all the coiled and blocky coils become Basically straight single fiber shape, and in this process, remove the broken seeds, impurities and short fibers left over from the cleaning process, and ...
