Improvement of Dust Removal Knife Holder in Carding Machine

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

Main clearance of cotton dust, two combing steps (headquarter noil dust more than 80%). During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. 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. 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 cleaning machine cannot remove broken seeds, debris, neps, dust, etc., and the card must be removed, otherwise the breakage rate will increase parking fees, hinder production, and affect quality. In order to make good spinning fiber does not become waste, and noil is formed by broken seeds, dust, neps, dust in the subsequent process without drafting rollers and cannot be controlled, etc., and the surface roller carding machine dust removal knife Adjustments must be made. Proper adjustment can not only save cotton, but also effectively reduce the breakage rate and parking rate in future processes, which plays a great role in the development of enterprises to increase social production and improve the quality of life.

The noil requirements after the carding machine are ideal, mainly to adjust the cotton plate, the burr roller and the dust collector, and the distance between the leakage bottom and the licker-in roller should be appropriate. On the card, the cotton plate and burr roller can be moved up and down, back and forth, while the dust removal knife can be moved up and down to correct (Fig. 1).

After research on various distances, before and after, and high and low experiments, there are only formal differences in the falling ball situation, and a reasonable and normal falling ball state still cannot be obtained. Later, we found that there are two problems that have a greater impact on the effect of cassette dust removal, that is, the angle of the dust removal knife is not suitable. When the angle of the dust removal blade is small, the dust removal blade is more efficient, but the fibers are easily damaged.

The angle of the dust knife unit is not suitable. Due to the inconvenient adjustment of the original knife holder (as shown in Figure 5), when the angle of the dust knife device is corrected, it cannot adjust the position of the dust knife (height and distance to the cotton board, etc.), and when the position of the dust knife is corrected, the blade cannot be adjusted. angle. In view of the above two problems, the carding machine has been transformed.

Dust card insertion is a single-pole, single-pole dust-removing knife has a large impact, but easily damages the fibers of different poles; a small-pole dust-removing knife has a large effect, but in addition to short fibers, it has a large impact. As shown in FIG. 2, the angle of the blade 29 is replaced by the blade 42 (FIG. 3) when the blade 48 (FIG. 4). Also with a curved angle bracket holder, original bracket 5, improved tool holder 6, the main difference is the non-rotatable tool holder.

The improved tool holder is A, B by two iron plates, iron plate B is fixed to the vehicle body wall, using the plane C at right angles to the plane of the wall movement can be done, through the RA central iron chain Road connecting screw iron level in B, d because of the arc slot of E fitted on the side plate so that the plate can move on the arc, F, the two adjusting screws G represent the connecting screws in correction j, The dust knife K makes the front and rear parts, and the level of various inclination angles can be moved as desired, flexible application, and different calibration of cotton in different ways to achieve the most reasonable normal state of noil. The following is an experiment we can do, with two different weights of completely equal laps (34 pounds net), respectively, on car No. 1 (after improvement) and car No. 2 (before improvement). Before the test, the wires of the two cars were cleaned, the front and rear belly of the car were cleaned, and the body structure was cleaned and tested. As a result, the output of the No. 1 car was 0.42 pounds more than that of the No. 2 car, and the broken seeds were also reduced by 0. .
