Carding machine

Abstract

A carding machine is provided. The carding unit comprises multiple rollers successively and adjacently arranged along its arranging surface, wherein a constant velocity roller is arranged between two variable velocity rollers and a variable velocity roller at both sides of the constant velocity roller. Driven by the driving mechanism, the constant velocity roller rotates at a preset rotating speed while the variable velocity roller at a variable speed; and in a rotating cycle, the speed of the variable velocity roller at one side of the constant velocity roller first turns from low to high and then from high to low, while the speed of the variable roller at the other side turns simultaneously from high to low and then from low to high; in addition, the liner speed of the variable velocity roller turns to be lower than that of its adjacent constant velocity rollers when it turns from high to low, and turns to be higher than that of its adjacent constant velocity rollers when it turns from low to high.

Description

technical field [0001] The invention generally relates to textile raw material preparation technology, in particular to a carding machine with little damage to fluff fibers and high production efficiency during the carding process. Background technique [0002] Patent document CN100335693C discloses a kind of carding method, this method adopts two adjacent carding rollers to strip and comb at variable speeds, when one of the rollers rotates at a high speed, the other roller rotates at a low speed, and the high-speed roller strips the low-speed roller Then the high-speed roll slows down and changes to a low-speed roll, and the low-speed roll speeds up and changes to a high-speed roll. The high-speed roll strips the fibers on the low-speed roll, and repeats stripping and transfer to realize carding. One or two of the rollers also reciprocate along the axial direction while rotating at variable speeds to transfer the fibers from one section of the roller to another section. Th...

AI Technical Summary

Problems solved by technology

Moreover, the stripping can usually be completed when the speed ratio is not changed much; at this time, even if the speed ratio is increased, the stripped roller has no fiber for stripping

This can only be stripped and carded at a small speed ratio, which leads to the inefficiency of the carding process

This phenomenon can be alleviated by increasing the rotational speed and change rate, but it cannot fundamentally solve the problem of low carding efficiency

In specific production, the number of times of stripping and carding can only be increased, such as repeated carding process, in order to obtain the required lint-free, which leads to low productivity
