AI Technical Summary
Existing brush drive devices cannot be precisely adjusted to the appropriate position when cleaning round combs, resulting in increased brush wear, which affects cleaning effect and service life.
The brush is driven by a servo motor. The brush moves linearly within the guide rail via a guide plate and guide wheel, ensuring that it remains tangent to the round comb and doffer. The linear speed is precisely adjusted by combining the servo motor and reducer.
It enables precise adjustment of the brush position, improves cleaning effect, extends brush life, reduces wear and tear, and enhances fiber parallelism and yarn quality.

Abstract
Description
Technical Field
[0001] This invention relates to a brush driving device, which is mainly used in combing machines and belongs to the technical field of textile machinery. Background Technology
[0002] In wool spinning and blended combing processes, combing machines are used to remove short fibers, straw, and impurities, improving fiber parallelism and uniformity, thereby enhancing yarn quality. Combing machines are generally equipped with a brush cleaning system, which uses a high-speed rotating brush roller to brush the surface of the circular comb in reverse, achieving continuous automatic cleaning. The brush drive device is a key component of this system, responsible for providing stable, adjustable, and coordinated rotational power to the brushes. Existing technologies almost always use fixed brushes, requiring cumbersome manual adjustments and making it impossible to precisely adjust them to the appropriate position for cleaning the circular combs. Therefore, this invention is proposed. Summary of the Invention
[0003] In view of the above-mentioned technical problems of the prior art, the purpose of the present invention is to provide a brush driving device that can linearly move the position of the brush, so that the brush, the round comb, and the doffer are always tangent. It can accurately adjust the linear speed after the brush wears down, so that the adjustment of the brush meets the process requirements, the adjustment accuracy is more precise, the product quality is improved, the service life of the brush is increased, the wear is reduced, and the quality and grade of the bristles are improved.
[0004] To achieve the above objectives, the invention is implemented through the following technical solution: A brush driving device includes a wall panel, on which a brush servo motor and a brush servo motor are mounted. The brush servo motor is connected to the brush and drives the brush to work. The brush servo motor is connected to a guide plate, and the guide plate is provided with a guide wheel. The guide wheel is located inside a guide rail. The brush servo motor drives the guide plate to translate within the guide rail, thereby causing the brush to move parallel within the guide rail.
[0005] The guide plate is equipped with a servo motor mounting base, and both the brush servo motor and the brush servo motor are mounted on the servo motor mounting base.
[0006] The output end of the brush servo motor is equipped with a lead screw, which is connected to the servo motor mounting base by a nut.
[0007] Friction plate one and friction plate two are installed on the wall panel, and a guide rail is formed between friction plate one and friction plate two. The guide wheel includes an upper row of guide wheels and a lower row of guide wheels. The upper row of guide wheels moves along the inner wall of friction plate one, and the lower row of guide wheels moves along the inner wall of friction plate two.
[0008] Both friction plate one and friction plate two are provided with several impurity discharge grooves.
[0009] The guide plate has a groove on the side away from the guide wheel, and the wall plate has a compression spring located in the groove.
[0010] Friction plate three is provided on one side of the guide rail, and the compression spring is provided on friction plate three.
[0011] The compression spring is provided with a compression spring sleeve on its outside.
[0012] The brush is equipped with a baffle on its exterior.
[0013] The brush servo motor is equipped with a speed reducer.
[0014] The beneficial effects of this invention are as follows: The brush driving device of this invention uses a brush servo motor to drive the brush independently, and the brush servo motor drives the lead screw, causing the brush to rotate while moving linearly within the guide rail. This allows the brush to be adjusted to the most suitable position when cleaning the round comb, ensuring that the brush, round comb, and doffer are always tangent. It can precisely adjust the linear speed after the brush wears down, making the brush adjustment meet the process requirements, improving the accuracy of adjustment, and enhancing product quality. During this process, fine hairs can also be discharged from the impurity discharge groove, making it easier for the doffer to clean short fibers and grass debris from the brush, increasing the brush's service life, reducing wear, and improving the cleaning effect.

Detailed Implementation
[0016] The present invention will be further described below with reference to specific embodiments, but the scope of protection of the present invention is not limited thereto.
[0017] like Figure 1-3As shown, the brush driving device of the present invention includes a wall plate 1, on which a brush servo motor 8 and a brush servo motor 4 are mounted. The brush servo motor 8 is equipped with a reducer 9, which connects to the brush 2. A baffle 3 is provided on the outside of the brush 2. The brush servo motor 4 is connected to a guide plate 10, which is equipped with a guide wheel 11 located inside a guide rail. The brush servo motor 8 drives the brush 2 to work, and the brush servo motor 4 drives the guide plate 10 to move horizontally within the guide rail, thereby driving the brush 2 to be parallel within the guide rail. This allows the brush 2 to be adjusted to the most suitable position when cleaning the round comb, ensuring that the brush 2, the round comb, and the doffer are always tangent, reducing wear and improving the cleaning effect.
[0018] Furthermore, the guide plate 10 of this invention is equipped with a servo motor mounting base 7. The reducer 9 of the brush servo motor 8 is mounted on the servo motor mounting base 10. The output end of the brush servo motor 4 is equipped with a lead screw 5, which is connected to the servo motor mounting base 10 by a nut 6. Friction plates 12 and 13 are mounted on the wall plate 1, forming a guide rail between them. The guide wheel 10 includes an upper row of guide wheels and a lower row of guide wheels. Generally, both the upper and lower rows of guide wheels have 2-3 guide wheels 10. The upper row of guide wheels moves along the inner wall of friction plate 12, and the lower row of guide wheels moves along the inner wall of friction plate 13. When the brush servo motor 4 is working, the lead screw 5 rotates, driving the servo motor mounting base 7 to move, thereby driving the guide wheel 11 on the guide plate 10 to move linearly along the inner walls of friction plates 12 and 13.
[0019] Furthermore, to make the linear movement of the entire brush 2 more stable, the guide plate 10 of the present invention has a groove 15 on the side away from the guide wheel 11, and a friction plate 3 18 on one side of the guide rail. A compression spring 16 with a compression spring sleeve 17 is set on the friction plate 3 18. When the groove 15 moves left and right with the guide plate 10, the compression spring 16 is always located in the groove 15 to press one side of the guide plate 10, prevent the guide plate 10 from being subjected to force on one side, and make the guide plate 10 always stable during the movement.
[0020] In addition, both friction plate 12 and friction plate 13 in this invention are provided with several impurity discharge grooves 14, which makes it easier for the doffer to clean short fibers and grass debris from the brush and prevent clogging.
[0021] The present invention can move the position of the brush 2 in a straight line, so that the brush 2, the round comb, and the doffer are always tangent, thereby increasing the service life of the brush 2, reducing wear and tear, and improving the cleaning effect.
[0022] The above embodiments are only used to explain the inventive concept of the present invention, and are not intended to limit the protection of the present invention. Any non-substantial modifications made to the present invention using this concept should fall within the protection scope of the present invention.
