Specification of card licker-in saw blade

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

The figure below is the specification drawing of the licker-in saw blade of the carding machine, in the figure the working angle isα, tooth pitch P, tooth tip thickness b, base thickness W and total height H are the main technical specifications, among whichα, P and b have the greatest impact on the carding effect of enterprises. 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). The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. 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. The research material for the saw surface has been low carbon steel in the past, and 45 steel is now used in order to improve its own hardness and wear resistance. The size of the working angle directly affects the ability of a sawtooth to pierce the cotton layer.αSmall, the saw blade has strong piercing ability, but too small is not good for impurity removal.

Current Social Work Cornerα, spinning cotton can generally use 75-80°. Spinning chemical fiber and medium-grown fiber development also have us using 80-90°of. The tooth pitch P is 5.644 mm (tooth per inch), and the lateral development density of the sawtooth structure is 8 grooves per 25.4 mm, then the sawtooth defect density per (25.4 mm) N = (25.4/ 5.644) x 8 = 36 teeth / (25.4 mm).

When the transverse value densities of the teeth on the licker-in are the same, the tooth pitch P is the direct influence factor of the tooth density. The thickness b of the tooth tip of the card licker-in roller is thick, medium and thin, and thin. Generally, the problem of tooth tip thickness b below 0.3 mm is called thin tooth.

The thickness of the tooth tip is 0.4 mm for the thick tooth. Thin-tooth puncture has strong technical ability and good combing. Less damage to fiber cells, less noil rate, and increased noil impurity content.
