Fiber transfer between card licker-in and cylinder

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

After the carding machine combs the fiber licker-in, the impurities, the saw teeth should transfer all the fibers to the clamping cylinder, and the incomplete transfer quickly fills the saw teeth, reducing or losing the carding ability of the licker-in, resulting in a large number of neps. 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.

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).

Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame. transfer to the slave licker-in, is performed (arc length S≈57 mm) in a segment of the arc, close to the cylinder to score the fiber in the cylinder.

The fiber has a linear velocity ratio from a cylinder with a serrated surface facing the licker-in needle transmission factors into the forest and the licker-in set, centrifugal force, size and density of needle teeth, draft resistance and fiber length. The teeth are arranged on the licker-in through the needle cylinder, the surface speed of the cylinder is greater than the surface speed of the licker-in, and the relative movement of the cylinder roller along the direction of the licker-in is inclined to the direction of the aluminum, so it is easy to get stuck and peeled off from the fiber. Serrated series cylinder thorns. When spinning cotton usually, a linear speed of 1.3 to 1.7 times the linear speed of the cylinder licker-in can make the fiber transfer smoothly.

When using long fibers or synthetic fibers, it should be increased to 1.6-2 times as well. In the analysis of the optical fiber transmission, the fibers in the licker-in are serrated, and more fibers are turned around without transferring the drum. It can be seen that the action of centrifugal force contributes to the zigzag shape of the fiber exit licker-in, and the flat needle cylinder is thrown.

The licker-in torch and the cylinder chamber have an important relationship with the transfer fiber, and a more complete transfer of smaller gauges, typically 0.13-0.18 mm. The gauge is small, the needle cylinder raises the fiber clamping action, and the fiber grabbing at the licker-in serration is conducive to the transfer of more exposed forest tips. In addition, the specification of sawtooth, the density of the tooth needle, and the transfer fiber of the cylinder are the factors that affect the cylinder.
