Abstract

The invention provides a spiral adjustable thermoelastic carding device, a carding cover plate and a carding machine. The spiral adjustable thermoelastic carding device comprises a carding needle, a spiral spring and a base, the carding needle is positioned above the spiral spring, the upper end of the spiral spring is connected with the bottom of the carding needle, the lower end of the spiral spring is fixed in the base, a base cloth is arranged above the base, the base cloth transversely penetrates through a spring gap of the spiral spring, an electric heating ceramic sheet is arranged inside the base, the electric heating ceramic sheet is connected with the spiral spring, and a transmission gear is arranged below the base. The spiral adjustable thermoelastic carding device has the beneficial effects that comb needles are heated through the electrothermal ceramic sheet, thus, when the comb needles comb fibers, the fibers soften and the rigidity is reduced, the carding efficiency andquality can be improved, and the fiber straightening parallelism can be improved; and the spiral spring is arranged at the lower ends of the comb needles, so that the action force of the fibers can be effectively buffered by the comb needles in the combing process, and damage of the comb needles to the fibers is reduced.

Description

technical field [0001] The invention relates to the technical field of textile processing, in particular to a spiral adjustable thermoelastic carding device, a carding cover plate and a carding machine. Background technique [0002] Fiber straightening parallelism, fiber strength and length are important factors affecting yarn quality. One of the main functions of carding is to improve the straightening parallelism of fibers in the sliver. The improvement of fiber straightening parallelism can effectively ensure The length of the fiber is beneficial to reduce noil, and is beneficial to the stability of the fiber speed change point in the drafting process, and to improve the evenness of the yarn, the strength of the yarn, and the hairiness of the yarn. Therefore, it is very important to improve the parallelism of fiber straightening and ensure the fiber length. [0003] However, existing carding machines generally have problems such as low carding efficiency, poor carding qu...
