Embodiment Construction

[0012] Such as figure 1 The arc-shaped pre-carding device shown includes a licker-in roller 1, a suction and impurity removal unit 2, a dust removal knife 3, a carding plate seat 4 and a cotton support adjustment plate 5, and an arc-shaped carding plate is installed on the carding plate seat 2. The arc-shaped pre-combing rack 6 formed by the combination of tooth pieces, the length of the tooth surface of the arc-shaped pre-combing rack 6 is 30mm-36mm, and the tooth tip direction is opposite to the rack tooth tip direction of the licker-in roller 1 .

[0013] In practice, one or two sets of arc-shaped pre-carding devices can be installed according to different types of carding. For example, a small drain bottom can be installed in the place where the second set of arc-shaped pre-carding devices is installed behind one set of arc-shaped pre-carding devices. Instead, be flexible. According to the running direction of the lap, there are licker-in roller 1, air suction and impurit...

Abstract

The invention relates to an arch pre-carding device, comprising cubing rolls, an air drafting and impurity removing unit, a mote knife, a carding panel seat and a cotton holding and adjustment plate, wherein, the carding panel seat is equipped with arch pre-carding racks formed by combining arch bits. The invention employs arch pre-carding racks, therefore, carding points are greatly increased, carding is carried out completely, softly and cautiously, fiber loss is little and the fibrous bundle which enters into the cylinder work area is small and little, so as to reduce the load of card clothing of a cylinder cover board, improve the carding quality and reduce neps.

Description

technical field [0001] The invention relates to a pre-carding device of a carding machine in textile machinery production, in particular to an arc-shaped pre-carding device applied to a cotton spinning carding machine. Background technique [0002] The licker-in rollers of the carding machine in the prior art all use licker-in rollers and ordinary straight-toothed racks for pre-carding. Due to the small diameter of the licker-in rollers, the diameter of the licker-in rollers of imported and domestic carding machines is mostly φ250mm, so it is different from straight teeth When the pre-combing racks are combed, only 30% of the racks participate in the combing. The degree of carding is small, the carding is not sufficient, it is easy to damage the teeth and fibers, and affect the carding quality, and because the density of the teeth in the pre-carding area cannot be increased, the difficulty of subsequent carding will be increased if the efficiency is to be improved, and the p...
