Conventional carding machines suffer from low efficiency and high levels of residual impurities in fiber opening, impurity removal, and carding, impacting the quality and efficiency of subsequent spinning processes. Therefore, developing a carding machine that can efficiently remove impurities and optimize fiber alignment has become a pressing challenge in the textile machinery industry.

[0003] After searching, the Chinese patent publication number CN220999986U discloses a cotton yarn carding machine with adjustable combing needles.

[0026] See also Figures 1 to 6 The impurity-removing carding machine of the present invention comprises a hollow body 1, wherein the body 1 is provided with a carding cavity 2, a cylinder cavity, a doffer cavity and a strip-forming mechanism; a cotton inlet 3 is opened on the top of the body 1, the cotton inlet 3 is connected with the carding cavity 2, the carding cavity 2 is connected with the cylinder cavity, the cylinder cavity is connected with the doffer cavity, and the doffer cavity is connected with the strip-forming mechanism; a vibrating carding mechanism and a trash suction mechanism are provided in the carding cavity 2; the vibrating carding mechanism comprises a first roller 4, which is a hollow cylinder, and the end face of one end of the first roller 4 is rotatably arranged on the inner side wall of the body 1; a plurality of vibration cavities 5 are provided in the first roller 4, and a plurality of scraping knives 6 are provided on the outer roller surface of the first roller 4; the trash suction mechanism comprises an arc-shaped filter screen 7 arranged on the side corresponding to the carding cavity 2 and the first roller 4, and an air suction part arranged outside the body 1; the arc-shaped filter screen 7 is connected to the air suction part;

[0027] In this embodiment, the material is conveyed into the combing chamber 2 through the cotton inlet 3, and then rotated by the first roller 4, causing the vibration chamber 5 to vibrate, and the vibration is transmitted to the material through the outer surface of the first roller 4, so that the material is loosened; the loosened material is conveyed to the arc filter 7 by the cotton scraper 6, and smaller cotton wool and other impurities are sucked out of the body 1.

[0028] In order to enable the vibration chamber 5 to vibrate, in the present invention, a plurality of vibration beads 8 are provided in the vibration chamber 5 ; the outer wall of the vibration chamber 5 is in contact with the inner wall of the first roller 4 .

[0029] In this embodiment, the rotation of the first roller 4 causes the vibrating beads 8 in the multiple vibration chambers 5 to be thrown up or dropped. During this process, the vibrating beads 8 collide with each other and with the inner walls of the vibration chambers 5, generating vibrations. The inner walls of the vibration chambers 5 then transmit the vibrations through the first roller 4 to the material, loosening it and facilitating the removal of impurities.

[0030] In order to further enhance the function of the first roller 4, the present invention further provides a counter-pressing roller 9, which is arranged in the combing chamber 2 and is arranged in the same direction as the first roller 4; the counter-pressing roller 9 is rotatably connected to the inner wall of the machine body 1; a first pulley 10 is fixedly provided at one end of the counter-pressing roller 9;

[0031] In this embodiment, the function of the first roller 4 is further enhanced by providing the pressing roller 9 .

[0032] In the present invention, a first motor 11 is further provided on the outside of the machine body 1, and a second pulley 12 is coaxially fixedly provided on the output shaft of the first motor 11; the second pulley 12 is connected to the first pulley 10 through a belt 13;

[0033] In this embodiment, the first motor 11 drives the second pulley 12 of its output shaft to rotate, the second pulley 12 rotates the first pulley 10 through the belt 13, and the first pulley 10 then drives the pressing roller 9 to rotate.

[0034] In order to further enhance the coordination effect between the pressing roller 9 and the first roller 4, in the present invention, a first gear 14 is coaxially provided at one end of the pressing roller 9, and a second gear 15 is provided at the same end of the first roller 4; the first gear 14 meshes with the second gear 15;

[0035] In this embodiment, the pressing roller 9 drives the first gear 14 to rotate clockwise, and the first gear 14 drives the first roller 4 to rotate counterclockwise through the second gear 15.

[0036] In this embodiment, after the material enters the carding chamber 2, it falls between the counter-pressing roller 9 and the first roller 4; the counter-pressing roller 9 and the first roller 4 turning in opposite directions can prevent the material from not being taken away by the scraper 6, and thus falling directly into the next process.

[0037] In order to prevent the pressing roller 9 from taking away the material, in the present invention, the roller surface of the pressing roller 9 is a smooth structure;

[0038] In this embodiment, the smooth structure can reduce the adhesion between the cotton yarn and the counter-pressing roller 9.

[0039] In order to further prevent the pressing roller 9 from taking away the material, in the present invention, an oblique scraper 16 is provided in front and back of the combing chamber 2. The upper end of the oblique scraper 16 is connected to the combing chamber 2, and the lower end of the oblique scraper 16 is in contact with the roller surface of the pressing roller 9.

[0040] In this embodiment, when the pressing roller 9 is rotated, when there is material adhering to the pressing roller 9 , the material can be scraped off by the oblique scraper 16 .

[0041] In order to further facilitate the discharge of impurities, the air intake portion includes an air collecting hood 17 arranged on the other side of the arc filter 7. The air collecting hood 17 is connected to multiple air intake pipes 18, and the air intake pipes 18 are connected to multiple fans 19.

[0042] In the present invention, the cylinder chamber, doffer chamber and strip forming mechanism are all existing technologies in this field, and their principles are not described in detail here.

[0043] Example:

[0044] When the material needs to be cleaned, it is fed through the cotton inlet 3 and falls between the counter-pressing roller 9 and the first roller 4. The counter-pressing roller 9 and the first roller 4 rotate in opposite directions, allowing the material to be caught on the scraper 6. As the first roller 4 rotates, the vibrating beads 8 within the vibration chamber 5 are ejected or dropped. During this process, the beads 8 collide with each other and with the inner walls of the vibration chamber 5, generating vibrations. The inner walls of the vibration chamber 5 then transmit the vibrations through the first roller 4 to the material, loosening it. When the material reaches the curved filter 7, impurities in the loosened material are removed. As the scraper 6 rotates, it scrapes the material off the curved filter 7. Simultaneously, the vibrating first roller 4 shakes off any cleaned material that remains attached to the lower roller surface and the rotating scraper 6, improving the efficiency of the first roller 4. The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of the claims of the present invention.
