For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0025] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a stacked tooth structure for a mid-doff carding machine, comprising: The carding roller 1 is equipped with a tooth stacking adjustment mechanism. It should be noted that the tooth height can be adjusted according to actual needs, eliminating the need for frequent tooth roller replacement and improving production efficiency. The tooth stacking adjustment mechanism includes combing tooth stacking 3, connecting plate 4, sliding plate 5, disc 9, ear plate one 10, ear plate two 11 and rotating component 12; The carding teeth 3 are slidably mounted on the carding roller 1. The carding teeth 3 are fixedly connected to the connecting plate 4. The slide plate 5 is fixedly connected to the connecting plate 4. The slide plate 5 is slidably mounted on the carding roller 1. Ear plate 10 and ear plate 21 are fixedly mounted on the disc 9 and the connecting plate 4 respectively. The rotating part 12 is hinged to ear plate 10 and ear plate 21.

[0027] With the above structure, when the tooth height needs to be adjusted, the two discs 9 move towards each other, which in turn causes the ear plate 10 to drive the rotating component 12 to rotate. The rotating component 12 drives the connecting plate 4 to move through the ear plate 2 11. The connecting plate 4 drives the combing stacked teeth 3 to move, thereby adjusting the position of the combing stacked teeth 3. The tooth height can be adjusted according to actual needs, eliminating the need for frequent tooth roller replacement and improving production efficiency.

[0028] Specifically, the tooth stacking adjustment mechanism also includes a vertical plate 6, a servo motor 7, and a rotating shaft 8. The vertical plate 6 is fixedly installed inside the carding roller 1, the servo motor 7 is fixedly installed on the vertical plate 6, the output end of the servo motor 7 is fixedly connected to the rotating shaft 8, the rotating shaft 8 is rotatably installed on the vertical plate 6, the outer side of the rotating shaft 8 is provided with a bidirectional thread, and a screw hole is opened on the disc 9, with the bidirectional thread and the screw hole threadedly connected.

[0029] With the above structure, starting the servo motor 7 will cause the rotating shaft 8 to rotate, and the two disks 9 can move towards each other through the cooperation of the bidirectional thread and the screw hole.

[0030] Specifically, a stabilizing plate 13 is fixedly installed on the disc 9, and a stabilizing hole is opened on the side of the upright plate 6. The stabilizing plate 13 is slidably installed in the stabilizing hole. It should be noted that this allows the disc 9 to move stably in the lateral direction.

[0031] Specifically, the carding roller 1 has a hole 14, and the carding teeth 3 are slidably installed in the hole 14. There are multiple sets of carding teeth 3, and the multiple sets of carding teeth 3 are arranged in a ring with equal spacing. It should be noted that this is to facilitate the movement of the carding teeth 3.

[0032] Specifically, a groove is provided on the inner wall of the carding roller 1, and the slide plate 5 is slidably installed in the groove. A drive shaft 2 is fixedly installed at the end of the carding roller 1, and a storage battery is fixedly installed inside the carding roller 1. It should be noted that the servo motor 7 is powered by the storage battery.

[0033] Working principle: S1: When it is necessary to adjust the height of the carding teeth 3 according to the fiber thickness and toughness, the servo motor 7 powered by the battery inside the carding roller 1 is started. The output end of the servo motor 7 drives the rotating shaft 8 fixedly connected to it to rotate on the vertical plate 6. Since the rotating shaft 8 is provided with a bidirectional thread on the outside and the screw hole on the disc 9 is connected to the bidirectional thread, the rotating shaft 8 will drive the two discs 9 to move towards each other along the axis of the rotating shaft 8 when rotating. During the movement of the discs 9, the stabilizing plate 13 fixedly connected to the discs 9 will slide in the stabilizing hole on the side of the vertical plate 6. The cooperation between the stabilizing plate 13 and the stabilizing hole restricts the rotation of the discs 9, ensuring that the discs 9 only move stably along the axis of the rotating shaft 8, avoiding the subsequent adjustment action due to the offset of the discs 9. When the discs 9 move, the ear plate 10 fixed on its surface moves synchronously. Since the rotating part 12 is hinged between the ear plate 10 and the ear plate 11, the movement of the ear plate 10 will push the rotating part 12 to rotate around the hinge point, and then drive the connecting plate 4 fixedly connected to it to move through the ear plate 11. S2: The sliding plate 5 fixed at the bottom of the connecting plate 4 will slide in the groove on the inner wall of the carding roller 1. The guiding effect of the groove on the sliding plate 5 ensures that the connecting plate 4 moves stably only in the direction perpendicular to the axis of the carding roller 1. Finally, the connecting plate 4 drives the carding teeth 3 fixedly connected to it to slide in the hole 14 of the carding roller 1, realizing the adjustment of the height of the carding teeth 3 extending out of the surface of the carding roller 1. If the tooth height needs to be increased, the two discs 9 continue to move towards each other, pushing the carding teeth 3 to extend outward; if the tooth height needs to be reduced, the servo motor 7 reverses, and the rotating shaft 8 drives the discs 9 to move in the opposite direction, pulling the carding teeth 3 to retract into the carding roller 1. S3: After the height of the carding teeth 3 is adjusted to meet the needs of the current fiber, the carding roller 1 is installed in the designated position of the carding machine through the drive shaft 2 at the end of the carding roller 1. After the carding machine is started, the drive shaft 2 drives the carding roller 1 to rotate as a whole. At this time, multiple sets of carding teeth 3 arranged in a ring with equal spacing come into contact with the fiber layer transferred from the previous process. The adjusted height is used to open and card the fiber, remove short fibers and impurities, and transfer the uniform fiber web to the subsequent process. Throughout the process, the height of the carding teeth 3 remains stable to ensure consistent carding effect.
