[0053] Referring to Figure 1 andFigure 2 The working frame 10 is provided with a carding roller 30. The carding roller 30 is horizontally arranged and is arranged along the width direction of the belt 23. The end of the carding roller 30 is rotationally connected to the working frame 10, that is, the carding roller 30 can rotate on the working frame 10 with the central axis of the carding roller 30 as the axis. The carding roller 30 is located above the belt 23. A plurality of moving grooves 32 are arranged on the side wall of the carding roller 30 along the length direction of the carding roller 30. The plurality of moving grooves 32 are uniformly arranged along the circumferential direction of the carding roller 30. A plurality of carding rods 40 are inserted into each moving groove 32. The plurality of carding rods 40 are uniformly and spacedly arranged in the moving groove 32 along the length direction of the carding roller 30. Specifically, the carding rod 40 is perpendicular to the central axis of the carding roller 30. A cavity 31 is arranged in the carding roller 30. One end of the carding rod 40 extending into the cavity 31 is connected to the carding roller 30 through a connecting assembly 50. An adjusting assembly 60 is arranged in the cavity 31. The adjusting assembly 60 is connected to the connecting assembly 50 and is used to drive the connecting assembly 50 to move, so as to drive the plurality of carding rods 40 to simultaneously move close to or away from each other, so as to change the distance between adjacent carding rods 40, meet the carding requirement, and have wider applicability.

[0054] With reference to Figure 2 and Figure 3 The connecting assembly 50 includes a mounting rod 51 and a plurality of connecting rods 52. The mounting rod 51 is horizontally inserted into the cavity 31 and is arranged along the length direction of the carding roller 30. One end of the mounting rod 51 penetrates out of the carding roller 30, and the other end is rotationally connected to the inner wall of the cavity 31, that is, the mounting rod 51 can rotate on the carding roller 30 with the central axis of the mounting rod 51 as the axis. A plurality of connecting blocks 53 are sleeved on the mounting rod 51. The plurality of connecting blocks 53 are uniformly distributed along the length direction of the mounting rod 51.

[0055] With reference to Figure 2 and Figure 3 The adjusting assembly 60 includes an adjusting rod 61 and an adjusting block 62. The adjusting rod 61 is coaxially fixed to the mounting rod 51. The adjusting block 62 is inserted into one of the connecting blocks 53. The adjusting block 62 is sleeved on the adjusting rod 61 and is threadedly connected to the adjusting rod 61.

[0056] The manual driving mounting rod 51 rotates the end of the carding roller 30 to drive the adjusting rod 61 to rotate around the central axis of the mounting rod 51, and the carding rod 40 is limited by the moving groove 32, so that the carding rod 40 cannot drive the connecting block 53 to rotate on the mounting rod 51, so that the adjusting block 62 cannot rotate, and then the adjusting block 62 drives the connecting block 53 connected thereto to move along the length direction of the connecting rod 52, changes the distance between the adjacent connecting blocks 53, so that the end of the connecting rod 52 drives the next connecting rod 52 to rotate, so that the plurality of connecting rods 52 rotate by the same angle, so that the distance between the adjacent connecting blocks 53 moves by the same distance, drives the plurality of carding rods 40 to move synchronously in the moving groove 32, so that the distance between the adjacent carding rods 40 can be adjusted to adapt to different carding requirements, and the applicability is larger.

[0057] With reference to Figure 2 and Figure 4 , in order to increase the stability of the structure of the carding rod 40, a limiting block 411 is fixed on the side wall of the carding rod 40, and a limiting groove 321 is formed in the inner wall of the moving groove 32 along the length direction of the moving groove 32, and the limiting block 411 is inserted into the limiting groove 321 and can move in the limiting groove 321.

[0058] The inner wall of the limiting groove 321 abuts against the side wall of the limiting block 411, so that the carding rod 40 cannot move along the length direction of the carding rod 40, that is, the lengths of the plurality of carding rods 40 extending out of the carding roller 30 are consistent, so that the distances of the plurality of carding needles 43 extending into the fibers are equal, and uniform carding of the fibers is realized. At the same time, the limiting block 411 and the inner wall of the limiting groove 321 cooperate to limit the deflection of the carding rod 40, increase the stability of the structure of the carding rod 40, and facilitate the carding of the fibers by the carding needles 43.

[0059] With reference to Figure 2 and Figure 4 , wherein the carding rod 40 comprises a fixed tube 41 and a carding needle 43, one end of the fixed tube 41 is fixed with the connecting block 53, the other end extends out of the moving groove 32, the limiting block 411 is arranged on the side wall of the fixed tube 41, the carding needle 43 is provided with a rotating shaft 44, the rotating shaft 44 is arranged along the length direction of the moving groove 32, the torsional spring 45 is sleeved on the rotating shaft 44, one end of the torsional spring 45 is fixed with the carding needle 43, the other end is fixed with the mounting block 42, the mounting block 42 is inserted into the end of the fixed tube 41 away from the connecting block 53, and the outer side wall of the mounting block 42 is threadedly connected with the inner wall of the fixed tube 41.

[0060] When the fibers are wound together and move to the carding needle 43 under the drive of the conveying belt 20, at this time the carding needle 43 is inserted in the wound fibers, the conveying belt 20 still drives the fibers to move, so that the fibers exert a pushing force on the carding needle 43. When the winding of the fibers is not serious, the fibers can pass through the carding needle 43, that is, the pushing force of the wound fibers on the carding needle 43 is not enough to overcome the elastic force of the torsion spring 45, so that the carding needle 43 maintains the coaxial state with the fixed tube 41. In this process, the carding needle 43 carding the wound fibers, when the winding of the fibers is more serious, the fibers cannot pass through the carding needle 43, at this time the pushing force of the fibers on the carding needle 43 can overcome the elastic force of the torsion spring 45, so that the torsion spring 45 deforms, thereby making the carding needle 43 rotate around the rotating shaft 44, that is, the carding needle 43 is tilted away from the conveying belt 20, realizing that the carding needle 43 is separated from the overlapped fibers, reducing the possibility that the carding needle 43 is hooked by the pushing force of the fibers.

[0061] With reference to Figure 1 And Figure 5 When the carding needle 43 is carding the fibers, some lint will be wound on the carding needle 43, in order to prevent these lint from affecting the normal use of the carding needle 43, a brush 70 is fixed on the working frame 10, the brush 70 is vertically downward, a driving assembly 80 is arranged on the end wall of the carding roller 30, the driving assembly 80 is used to drive the water pipe to rotate around the central axis of the water roll, so that the carding needle 43 can pass through the brush 70 and slide on the brush 70,

[0063] When the motor is started, the incomplete gear 82 is driven to rotate, when the teeth on the incomplete gear 82 are engaged with the driving gear 81, the driving gear 81 is driven to rotate, so that the carding roller 30 rotates, the carding needle 43 rotates around the central axis of the carding roller 30, so that the carding needle 43 wound with lint moves to the brush 70 and slides on the brush 70, the brush 70 passes through the carding needle 43, so as to clean the carding needle 43, so that the carding needle 43 can card the fibers next time.

[0064] With reference to Figure 1 And Figure 4In order to improve the cleaning effect of the carding needle 43, a plurality of abutting plates 90 are arranged on the carding roller 30, the plurality of abutting plates 90 are arranged along the circumferential direction of the carding roller 30, the abutting plates 90 are arranged along the length direction of the carding roller 30, the abutting plates 90 are provided with abutting grooves 91 penetratingly arranged thereon, the abutting grooves 91 are communicated with the moving grooves 32, when the abutting plates 90 are abutted on the carding roller 30, the part of the fixed tube 41 penetrating out of the moving grooves 32 extends to the abutting grooves 91, the mounting block 42 connected with the end of the fixed tube 41 penetrates out of the abutting grooves 91, and the inner wall of the abutting grooves 91 abuts with the side wall of the mounting block 42.
