The old carding machines in our country have their own elastic card clothing a181 type, with the output of 4-6 kg / set, and then began to develop A181E and a181f type metal card clothing with the output of 15 kg / set and 9 kg / set. A18s type carding machine was designed and manufactured in 1965, and the output level was increased to 15-20 kg / set. A spinning machine that makes fibers into roving. The main function is drafting and twisting, and the roving is wound into a certain package to meet the requirements of spinning machine processing. The structure of double twist unit of double twist machine mainly includes spindle brake device, spindle part of double twist machine, yarn winding device, special device of double twist unit, etc. Carding machine is used to process cotton fiber and chemical fiber, belonging to textile machinery. According to the spinning process, carding is an important process. The former process of carding machine is opening and cleaning combine, and the latter process is drawing frame (carding process) or coiler (combing process).

The iron gun of carding machine is responsible for managing and controlling the speed (variable speed and part) of bobbin winding system and driving the upper bar in carding machine. In the spinning process of spinning machine, the semi-finished roving or sliver is drawn, twisted and wound into spinning tube yarn, the sliver is drawn and twisted on the roving machine to make roving, the fiber is combed on the comber to make combed sliver, the sliver is combined on the card machine, the structure of the sliver is improved by the needle row drafting, and the roving is further twisted on the ring spinning machine to make spinning, Spinning frame is the main spinning machine. Winder is a special equipment for textile industry. As the last process of spinning and the first process of weaving, winding plays an important role in the textile field. The structure of double twist unit of double twist machine mainly includes spindle brake device, spindle part of double twist machine, yarn winding device, special device of double twist unit, etc. At present, most enterprises adopt a hyperbolic iron gun, which is composed of a pair of Chinese upper and lower iron guns (see Figure 7-19). The upper iron gun rotates at a constant speed and drives the lower iron gun through the iron gun belt. When the belt position is changed, the transmission ratio of the upper and lower iron guns of the company can be changed to change the speed of the lower iron gun.

Learn the experimental research method of carding machine mixing other functions. A spinning machine that makes fibers into roving.
