[0024] Embodiment:

[0025] A cotton fiber carding device includes two relatively arranged fixed covers 1; a cylinder 2 and a plurality of working rollers 3 are arranged between the two fixed covers 1; the plurality of working rollers 3 are arranged in an arc shape around the cylinder 2. The fixed covers 1 are used to fix the cylinder 2 and the working rollers 3. The above setting method is a conventional setting method in the art, and no further detailed description is given in this embodiment. Those skilled in the art can also obtain the specific implementation manner of the above solution through conventional technical means in the art.

[0026] The working roller 3 is connected to the fixed cover 1 through an adjusting mechanism 4; the adjusting mechanism 4 includes a fixed fork, a fixing bolt 43 and a telescopic adjusting screw 44; the fixed fork includes a handle part 42 and a fork part; the fork part includes a first bracket 411 and a second bracket 412; the handle part 42 and the fork part are connected to form a "Y" - shaped structure; the bottom end of the fork part is arc - shaped, and a bearing is arranged on the fork part; a fixing groove 421 is arranged on the handle part 42; one end of the telescopic adjusting screw 44 is connected to the bottom end of the handle part 42; the bottom end of the fork part is arc - shaped and is matched with the bearing, which can better fix the bearing. On this basis, those skilled in the art should know that the above - mentioned adjusting mechanism 4 is arranged on both of the two fixed covers 1, and bearings are arranged on the fork parts of the adjusting mechanism 4; the outer ring of the bearing is connected to the fork part; both ends of the working roller 3 are respectively connected to the inner ring of the bearing. The independent rotation of the working roller 3 is realized through the above solution.

[0027] The fixed cover plate 1 is provided with a fixing unit; the fixing unit includes at least two fixing toothed plates and a fixing hole 12; a tooth groove 14 is formed between the fixing toothed plates; the other end of the telescopic adjusting screw 44 is inserted into the tooth groove 14; the telescopic adjusting screw 44 is provided with a first telescopic adjusting nut 443 and a second telescopic adjusting nut 444 which are respectively connected to both ends of the fixing toothed plate. When it is necessary to adjust the position of the adjusting mechanism 4 along the central axis direction of the handle 42, the first telescopic adjusting nut 443 and the second telescopic adjusting nut 444 are respectively rotated, and the two telescopic adjusting nuts move on the telescopic adjusting screw 44; since the position of the fixing toothed plate is fixed, the fixing fork will move along the central axis direction to achieve the purpose of adjustment. The handle 42 of the fixing fork points to the cylinder 2, and the gap between the working roller 3 and the cylinder 2 can be adjusted through the above solution. The fixing bolt 43 connects the fixing hole 12 and the fixing groove 421, and a fixing nut is arranged on the fixing bolt 43, and the fixing fork is fixed on the fixed cover plate 1 through the fixing nut. After the fixing bolt 43 is tightened, the fixing fork is closely attached to the fixed cover plate 1 to achieve the technical effect of fixation. Preferably, the width of the tooth groove 14 is adapted to the width of the telescopic adjusting screw 44 to prevent the fixing fork from generating displacement with the fixing nut as the center under the pressure of the working roller 3 after fixation; due to the clamping effect of the first telescopic adjusting nut 443 and the second telescopic adjusting nut 444, displacement in the central axis direction is avoided after fixation. Through the cooperation of the fixing toothed plate and the tooth groove 14, loosening the first telescopic adjusting nut 443 and the second telescopic adjusting nut 444 can complete the disassembly of the telescopic adjusting screw 44, with a simple structure and convenient operation.

[0028] In a possible embodiment, it further includes a first gasket 441 and a second gasket 442; the first gasket 441 is arranged between the first telescopic adjusting nut 443 and the fixing toothed plate; the second gasket 442 is arranged between the second telescopic adjusting nut 444 and the fixing toothed plate. The gasket can reduce the direct friction between the adjusting nut and the fixing toothed plate, reduce wear, and at the same time increase the contact area to improve the stability of the adjusting mechanism 4. The addition of the gasket enables the adjusting nut to be more precisely fixed at the required position and not easily loosen, thereby improving the accuracy of gap adjustment.

[0029] In a possible embodiment, the fixing bolt 43 includes a bolt head 431 and a bolt column, the bolt head 431 abuts against the fixing hole 12; the fixing nut is arranged on the bolt column; the fixing nut is located outside the fixed cover plate 1 and the fixing fork, and after the fixing nut is disassembled, the fixing bolt 43 will not fall off. If the scheme with the fixing nut inside is adopted, there are problems such as insufficient installation space for the fixing bolt 43 and the nut is easy to fall into the gap during disassembly. A fixing gasket is arranged between the fixing nut and the fixing groove 421. In addition to the above effects, the gasket can also increase the contact area and make the fixation more reliable.

[0030] In a possible embodiment, the fixing unit further includes a positioning block 11 provided on the fixing cover plate 1; a positioning cavity 453 is provided on the handle portion 42; a first screw 451 and a second screw 452 are respectively provided on the left and right sides of the positioning cavity 453; the positioning block 11 cooperates with the positioning cavity 453; the tops of the first screw 451 and the second screw 452 abut against the positioning block 11. By adjusting the depths of the first screw 451 and the second screw 452 extending into the handle portion 42, the position of the fixing fork can be adjusted in the arc direction, and further the gap between adjacent working rollers 3 can be adjusted.

[0031] In a possible embodiment, the fixing hole 12 is arc-shaped. The provision of the arc-shaped fixing hole 12 facilitates the adjustment of the position of the fixing fork along the arc direction.

[0032] In a possible embodiment, a first threaded post 461 and a second threaded post are respectively provided on the first bracket 411 and the second bracket 412; a fixing pressing plate 463 is further included; both ends of the fixing pressing plate 463 are respectively sleeved on the first threaded post 461 and the second threaded post; a first pressing plate nut 464 is provided on the first threaded post 461; a second pressing plate nut is provided on the second threaded post; a first spring is provided between the first pressing plate nut 464 and the fixing pressing plate 463; a second spring 462 is provided between the second pressing plate nut and the fixing pressing plate 463. The springs enable the fixing pressing plate 463 to play a buffering role when the working roller 3 is impacted, protecting the working roller 3 and the bearing from damage; for example, when hard foreign matters are mixed in the fibers, the working roller 3 can be prevented from being damaged by providing the springs; the close contact between the fixing pressing plate 463 and the bearing and the supporting effect of the springs improve the stability of the working roller 3 during high-speed rotation.

[0033] In a possible embodiment, the fixing pressing plate 463 includes an arc portion; the arc portion abuts against the bearing. The arc portion increases the contact area between the fixing pressing plate 463 and the bearing, makes the pressure distribution more uniform, and reduces local wear.

[0034] In a possible embodiment, a plurality of fixing units are provided on the fixing cover plate 1; the fixing units are distributed in an arc shape around the cylinder 2. By providing a plurality of fixing units, the problems of equipment expansion and adjustment are fully considered. The number of working rollers 3 and the installation positions of the working rollers 3 can be flexibly selected, making the carding machine more adaptable.

[0037] Improve carding effect: Since the gap can be precisely adjusted, the device can ensure that the working roller operates in the best state, neither too crowded nor too loose, thus improving the carding effect of cotton fibers. This helps to reduce fiber loss, improve the parallel straightness and sliver quality of cotton fibers, and ultimately improve product quality.

[0038] Enhance machine stability and durability: A reasonable gap setting helps to reduce friction and resistance during machine operation, reducing the risk of machine jamming or damage. At the same time, by precisely adjusting the gap, mechanical wear caused by improper gaps can be reduced, thereby extending the service life of the machine.

[0039] Compact structure and easy to maintain: The carding device of this utility model has a reasonable structural design, and the connection between components is tight and easy to disassemble. This not only facilitates daily maintenance and upkeep but also reduces maintenance costs.
