The middle part of the upper end of the two support cover plates 3 is fixedly connected to the lifting mechanism 5. The two lifting mechanisms 5 are provided with adjusting rollers 6. The outer sides of multiple support rollers 4 and an adjusting roller 6 are commonly connected to a movable cover plate group 8. The heel-toe rod 401 rotates inside the limiting tube 302 through multiple ultra-thin bearings 402. At the same time, the ultra-thin bearings 402 provide support between the heel-toe rod 401 and the limiting tube 302, so that the heel-toe rod 401 is isolated from the limiting tube 302, preventing the heel-toe rod 401 from direct contact with the limiting tube 302, which may cause severe wear of the heel-toe rod 401 after use.

[0026] Furthermore, a lifting groove 501 is provided inside the lifting mechanism 5 , a strip-shaped opening is provided between one side of the lifting groove 501 and the inner end surface of the lifting mechanism 5 , and a fixed shaft 601 is provided in the middle of the adjusting roller 6 .

[0027] Furthermore, the front and rear ends of the fixed shaft 601 extend out of the front and rear ends of the adjusting roller 6 and are respectively inserted into the two lifting grooves 501 along the strip opening. The front and rear ends of the fixed shaft 601 are respectively fixedly connected with sliders 602 inside the two lifting grooves 501. The two sliders 602 are simultaneously lifted and lowered inside the lifting grooves 501, and then the two sliders 602 drive the fixed shaft 601 to be lifted and lowered at the same time, so that the fixed shaft 601 drives the adjusting roller 6 to be lifted and lowered. When the adjusting roller 6 is in use, the middle part of the inner upper end of the movable cover group 8 is lifted a certain distance, so that the movable cover group 8 is tightened. By adjusting the height of the adjusting roller 6, the tightness of the movable cover group 8 can be adjusted to ensure the stability of the movable cover group 8 during rotation.

[0028] Furthermore, a screw rod 503 is rotatably connected to the middle part of the lifting groove 501, and the screw rod 503 is threadedly connected to the slider 602. A transmission groove 502 is provided inside the lifting mechanism 5 and at the upper end of the lifting groove 501. The upper end of the screw rod 503 extends into the transmission groove 502 and is fixedly connected to the first conical tooth 504.

[0029] Furthermore, a transmission shaft 7 is rotatably connected to the upper ends of the two lifting mechanisms 5. Both ends of the transmission shaft 7 extend to the inside of the transmission grooves 502 of the two lifting mechanisms 5 and are fixedly connected with second conical teeth 701. The second conical teeth 701 are meshed and connected with the teeth of the first conical teeth 504. The rotation of the transmission shaft 7 synchronously drives the two screws 503 to rotate, and then the two screws 503 synchronously drive the two sliders 602 to rise and fall.

[0030] Furthermore, a driving device 505 is fixedly provided on the outside of a lifting mechanism 5 , and a motor 506 is provided inside the driving device 505 .

[0031] Furthermore, one end of the transmission shaft 7 passes through the lifting mechanism 5 and extends to the interior of the driving device 505 and is fixedly connected to the output shaft of the motor 506, and the transmission shaft 7 is driven to rotate by the motor 506.

[0032] Working principle: When in use, first ensure that the cylinder 2 inside the carding machine frame 1 has been correctly installed, and the two ends of the rotating shaft 201 have been firmly connected to the support cover 3. Next, install multiple support rollers 4 between multiple corresponding two support members 301, and ensure that the heel-toe rods 401 at both ends of the support rollers 4 can be smoothly inserted into the limiting tube 302 and rotated through the ultra-thin bearings 402. The setting of the ultra-thin bearings 402 effectively isolates the direct contact between the heel-toe rod 401 and the limiting tube 302, thereby reducing the wear on the surface of the heel-toe rod 401 after long-term work. When the tension of the movable cover group 8 needs to be adjusted, it can be achieved through the motor 506 inside the drive device 505. After the motor 506 is started, its output shaft drives the transmission shaft 7 to start rotating. Because two second conical teeth 701 are fixedly connected at each end of the transmission shaft 7 and these two second conical teeth 701 mesh with the first conical teeth 504 within the two lifting mechanisms 5, the rotation of the transmission shaft 7 synchronously drives the two screws 503 to rotate. As the screws 503 rotate, the slider 602, threadedly connected to them, begins to move up and down along the lifting groove 501. Because the slider 602 is fixedly connected to the fixed shaft 601 of the adjustment roller 6, the lifting movement of the slider 602 drives the adjustment roller 6 to move up and down synchronously. By adjusting the height of the adjustment roller 6, the lifting distance of the middle portion of the inner upper end of the movable cover assembly 8 can be changed, thereby adjusting the tension of the movable cover assembly 8. Once the tension of the movable cover assembly 8 is adjusted to the appropriate position, the motor 506 can be turned off, and the carding machine can be started to operate normally. During the rotation of the movable cover assembly 8, because it is properly tightened, it can maintain a stable rotation state, effectively improving the carding effect of the carding machine.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
