China hemp fiber one-step fiber forming and carding machine

Abstract

The invention relates to a China hemp fiber one-step fiber forming and carding machine and belongs to the technical field of design and manufacturing of China hemp combined fiber forming and carding machines. Equipment is composed of a vehicle wallboard and an equipment body. The equipment body is composed of a feeding part, a carding region I, a carding region II and a net strip forming part. A transferring licker-in roller is arranged between a cylinder A and a cylinder B, and a doffer is arranged at the front part of the cylinder B. Transferring rollers above the cylinder A and the cylinder B are respectively provided with a small chain wheel. During operation, a hemp roll is unwound and fed to a roller to be held and then is fed into the cylinder A, a hemp layer is stripped and carded step by step in the cylinder A, then the hemp layer subjected to carding enters the cylinder B, carding treatment is carried out on the hemp raw material by virtue a working roller and a transferring roller, and finally the net strip is output. The machine provided by the invention has the characteristics of simple equipment structure, short operational process, one-step carding, less wet dissipation, optimum degree of carding strength, improvement of the split degree and increase of fiber length, thereby solving the problems of the existing equipment.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of hemp fiber-forming carding machines. Background technique [0002] At present, there are many equipments used for fiber carding of hemp plants, especially hemp and flax, etc. after degumming, among which there are flickers, carding machines, carding machines, etc. Primary carding followed by re-carding with a card. There are also graded combs that use flick machines entirely. The carding element of the flick machine is a saw blade, which belongs to the grip carding. When carding, the fibers are particularly damaged, and the poor carding quality results in low splitting and short fiber length. The carding machine is mainly based on the roller type carding. Although the fiber is kept at a certain length, the carding is not sufficient and the degree of splitting is still very low. The carding machine is mainly flat-type carding, and the carding force is relatively strong, which c...

AI Technical Summary

Problems solved by technology

No matter how the above-mentioned equipments are used in combination, it is difficult to produce high-quality products with a high degree of splitting and a certain length of fiber

In addition, there is another important problem. Because more equipment is used, the process is longer, and the primary carding raw materials are placed for a long time, resulting in a lot of moisture in the fiber, because the official moisture regain of hemp fiber is 12%, and the moisture absorption and release are very fast. Only Only when a certain moisture regain is maintained, the fiber will have a certain strength and softness, and high-quality fibers can be carded
