Usually, the metal card clothing is spiral in the tin card Lin and Dover, and I go around the wave tube. 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). The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. Special equipment for the textile industry on the winder.
As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field. The distance between the needle faces of the two thick cylinders is generally about 0.127mm. This method has the advantages of satisfying grievances and convenient adjustment.
However, when the edge of the cylin is turned, there is always a part of the fiber entering the air separation between the saw blades, which affects the carding effect. Finally, this unadsorbed fiber mixes with the sliver and affects the spinning quality. In order to eliminate and improve these unfavorable factors, the research of foreign carding machine proposes the method of wrapping metal clothing (8).
According to this method, first on the cylinder, a doffer thick cylinder is used to represent the annular groove engraved by the minister and a cross through the annular bad (eunuch or inclined well). Wrap the whole card clothing continuously. After wrapping the first circle, go through the transverse groove and enter the second annular groove, and wrap them in turn until the whole wave cylinder is wrapped. To prevent bumps during rotation, the top of the needle must be removed from the socket.
In addition to the general method of adjusting the gap between the doffer cylinder and the doffer cylinder, another adjustment method can also be used to make the depth of the two direct pin surfaces coincide, which is consistent with an appropriate depth of 0.254mm. Wrapping, compared to inclined helical wrapping, can reduce the spacing between the racks at the same time, reducing and sinking of fibers. Since the white tip of the doffer card clothing penetrates into the gap of the Xinjinlong card clothing rack, it quickly grabs away the fibers that gradually sink into the same gap. Ruan can reduce the fibrin deposition in the gap for the Xinjinlong rack, and the fork can Improve the transfer rate of streetwear clothing.
