The function of the stripping mechanism of the carding machine is to strip the fibers on the doffer needle teeth, and form a cotton web with a uniform structure, which is then transported to the large pressure roller. Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery. According to the spinning process, carding is an important process.

The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process). During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. Grinder A spinning machine that turns fiber strands into rovings.

The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame. The stripping mechanism mainly used in the carding machine is traditionally in the form of an oscillating chopper. But at present, a rotary roller stripping mechanism has been widely studied and used in the high-speed development and high-yield carding machine.

Carding machine swing chopper stripper In the blades of the doffer needle window, most of the fibers are fixed by one end of the doffer needle and the other end floats on the doffer tooth end. When the fiber moves to the minimum distance between the doffer and the cutter, the serrations on the swinging blade slope along the doffer pin teeth, striking and accelerating the fiber outward from the doffer pin teeth, as shown in Figure 2-23. At the same time, due to the friction and adhesion between the fibers, the doffer needles peel off on the surface of the fibers, forming a cotton web.

In terms of the nature of the motion, the high-speed chopper swing is obviously unreasonable, incompatible with the requirements of modern high-speed cards, and due to the chopper action, the reciprocal swing is discontinuous in stripping, resulting in short segments of uneven sliver. So, don't use this mechanism to keep hitting new highs, fast, and producing cards.
