Problems solved by technology

[0004] Because the feeding and carding system of this type of carding machine is too sufficient to the carding of fibers, as the disclosed technology of CN25575397 patent, the damage of fibers is relatively large, especially for hemp fibers and glass fibers, which are single fibers after carding, and the fibers are torn and damaged. severe fracture
And the carding machine for hemp fiber can only card the fiber below 120mm, and the long-cut fiber of 120mm-250mm cannot be carded. Because the long-cut fiber of 120mm-250mm is too long, it will wind around the work roll, causing the carding machine to crash and damage the carding equipment.
Therefore, the fiber forming felt prepared by carding with this kind of carding machine, the material made by the back-up process, its tensile, bending and other strength indicators are all affected, and cannot meet the characteristic requirements of special automotive interior materials

Abstract

The invention discloses a feeding and carding system of card clothing, characterized in that two to four pairs of carding region and two stripping regions are set on cylinder; the distance between principal up-down rollers is 10-70mm; the distance between secondary up-down rollers is 10-70mm, the distance between principal feeding roller and secondary feeding roller is 20-100mm, and the distance between principal feeding roller and thorny roller is 10-80mm. the invention is provided with smaller damage for fiber. Especially aiming to the carding for flax fiber, glass fiber, there is smaller tearing and rupturing to fiber. It can card cutting fiber with the length of 120mm-250mm. There is no influence to indexes such as drawing, bending of the fiber forming felt produced after prepared technology and so on and the product can satisfy the special demand of decoration material in special automobile. It is especially applied in carding for compound fiber, nature flax fiber, bamboo fiber, and glass fiber so on.

Description

technical field [0001] The present invention relates to a fiber carding machine, in particular to the feeding and carding system in the carding machine. Background technique [0002] Fiber carding machine is an important equipment for dry-laid nonwovens. However, the current fiber carding machine cannot complete the carding of long fibers longer than 150mm into a web, and there are no fiber bundles in the fiber web, so it cannot meet the performance requirements of special materials for automotive interiors. [0003] Common fiber carding machines, such as hemp fiber carding machines, are made up of main parts such as feeding rollers, licker-in rolls, work rolls, depilling rolls, pre-carding cylinders, cylinders, doffers, and chopping knives. The fiber is fed to the licker-in roller by the feed roller for preliminary opening and transfer, and then the fiber is fully combed and transferred through repeated carding and transfer between the pre-carding cylinder, the cylinder an...
