Technical Field

[0001] This invention relates to the technical field of fiber cleaning devices, specifically a fiber cleaning device for the hot rolling production of nonwoven cleaning fabrics. Background Technology

[0002] Nonwoven fabric is a type of non-woven material. It is made by directly forming fibers from polymer chips, short fibers, or filaments into a web through airflow or mechanical means, then reinforcing it through hydroentangling, needle punching, or hot rolling, and finally finishing it to form a non-woven fabric. It is a new type of fiber product with softness, breathability, and planar structure. Its advantages include no fiber dust, strength, durability, silky softness, and it is also a type of reinforcing material. It also has a cotton-like feel. Compared with cotton fabrics, nonwoven bags are easier to shape. During the hot pressing process of nonwoven fabric, it is necessary to use hot press rollers to hot press the nonwoven fabric. After long-term use, the fiber debris adhering to the surface of the hot press rollers needs to be cleaned. A Chinese patent document with publication number CN113770083B discloses a surface cleaning device for non-woven fabric hot rolling rollers. The device includes an arc-shaped protective cover and an arc-shaped connecting frame located inside the protective cover. Multiple sponge cleaning rollers for cleaning the hot rolling rollers are rotatably mounted on the connecting frame. An air collection box is fixedly installed on the outside of the protective cover. A connecting seat is provided on the side of the air collection box away from the protective cover, and a handle is provided on the side of the connecting seat away from the air collection box. The handle is movably mounted on the connecting seat by a second screw. However, in the above-mentioned solution, during the cleaning process of the pressure roller, the fiber debris cleaned off by the cleaning mechanism is very likely to fall onto the fabric forming table below, thereby affecting the product quality. Therefore, this invention proposes a fiber cleaning device for hot rolling production of nonwoven cleaning cloth to solve the above problem. Summary of the Invention

An upper connecting seat 14 and a lower connecting seat 15 are fixedly connected to the upper and lower sides of the mounting plate 2, respectively. The secondary rotating shafts 8 are driven by a servo motor on the mounting bracket 1. When the equipment is running, the primary rotating shaft 7 rotates clockwise, and the secondary rotating shaft 8 rotates counterclockwise. The primary cleaning mechanism 3 is fixedly mounted on the upper connecting seat 14, and the secondary cleaning mechanism 4 rotates counterclockwise. The cleaning mechanism 4 is fixedly installed on the lower connecting seat 15. The primary cleaning mechanism 3 and the secondary cleaning mechanism 4 are used to clean the surface of the hot press roller 6. The waste trough 5 is fixedly installed on the frame of the non-woven cleaning cloth hot rolling production equipment, and the waste trough 5 is located directly below the secondary cleaning mechanism 4. The primary cleaning mechanism 3 includes a mounting seat 9, a movable plate 10 and a cleaning needle 11. The mounting seat 9 is fixed on the upper connecting seat 14, and the outer side of the mounting seat 9 is provided with a movable plate groove 12. The bottom of the movable plate groove 12 is provided with a needle hole 13. The needle hole 13 and the cleaning needle 11 are correspondingly arranged. The movable plate 10 is movably arranged in the movable plate groove 12. The cleaning needle 11 is fixedly connected to the movable plate 10 and is movably arranged in the needle hole 13. The structure of the secondary cleaning mechanism 4 is the same as that of the primary cleaning mechanism 3.

[0019] A spring connector 16 is fixedly installed at the port of the movable plate slot 12 on the mounting base 9 by a positioning screw. A return spring 17 is fixedly installed on the inner side of the spring connector 16. The inner end of the return spring 17 abuts against the movable plate 10. When the return spring 17 is in the reset state, the cleaning needle 11 is fully retracted into the needle hole 13. A force-bearing rod 18 is fixedly connected to the outer side of the movable plate 10. The force-bearing rod 18 has an L-shaped rod structure, and the force-bearing rod 18 is positioned at both ends of the movable plate 10. It is said that a set of force-bearing components 19 are fixedly installed at both ends of the mounting bracket 1. The force-bearing components 19 include a primary force-bearing plate 21, a secondary force-bearing plate 22, and a tertiary force-bearing plate 23.

[0020] The force-bearing rod 18 is correspondingly arranged with the force-bearing component 19. When the cleaning mechanism moves towards the hot press roller 6, the force-bearing rod 18 and the force-bearing component 19 are separated. When the force-bearing rod 18 moves towards the primary force plate 21, the end of the cleaning needle 11 extends out from the needle hole 13. A fiber cleaning device for non-woven cleaning cloth hot rolling production is set up, which is composed of a mounting bracket 1, a mounting plate 2, a primary cleaning mechanism 3, a secondary cleaning mechanism 4 and a waste trough 5. The primary cleaning mechanism 3 and the secondary cleaning mechanism 4 are both set to be composed of a mounting base 9, a movable plate 10 and a cleaning needle 11.

L-shaped force-bearing rods 18 are set at both ends of the movable plate 10. The force exerted by the force-bearing component 19 on the force-bearing rods 18 controls the extension and retraction of the cleaning needle 11 from the needle hole 13. This allows the cleaning needle 11 to clean the hot press roller 6 while also facilitating the removal of fibers adhering to the cleaning needle 11. When the cleaning needle 11 retracts into the needle hole 13, the fibers on the cleaning needle 11 are pushed off the cleaning needle 11 and fall into the waste trough 5 for collection.

[0021] Example 2: Please refer to Figure 7-13 Based on Embodiment 1, the bottom of the movable plate groove 12 is provided with a force-bearing block groove 24, and a force-bearing block 25 is fixedly connected to the inner side of the movable plate 10. A set of force-bearing blocks 25 are symmetrically arranged at both ends of the movable plate 10. The force-bearing blocks 25 are movably arranged in the force-bearing block groove 24. The arc value of the end face of the force-bearing block 25 matches the arc value of the outer wall of the hot pressure roller 6. When the end face of the force-bearing block 25 is in contact with the outer wall of the hot pressure roller 6, the ends of all cleaning needles 11 are in contact with the outer wall of the hot pressure roller 6. Through the contact force of the force-bearing block 25 and the hot pressure roller 6, the contact effect of the cleaning needles 11 is guaranteed, and the cleaning needles 11 are prevented from being damaged by direct force on the hot pressure roller 6 when the primary cleaning mechanism 3 and the secondary cleaning mechanism 4 move relative to the hot pressure roller 6.

[0022] The end face of the cleaning needle 11 is fixedly bonded with a primary protective rubber layer 26, and the end face of the force-bearing block 25 is fixedly bonded with a secondary protective rubber layer 27. The surface of the hot press roller 6 is protected by the primary protective rubber layer 26 and the secondary protective rubber layer 27.

The movable plate 10, the cleaning needle 11, and the force rod 18 are all cast from conductive materials. By using conductive materials for the secondary force plate 22, the tertiary force plate 23, the movable plate 10, the cleaning needle 11, and the force rod 18, and using insulating materials for the primary force plate 21, grounding the secondary force plate 22 through the primary conductor 28, and connecting the tertiary force plate 23 to the electrostatic generator through the secondary conductor 29, static electricity is generated on the cleaning needle 11, thereby effectively improving the cleaning effect of the cleaning needle 11 on the fibers of the hot press roller 6.

[0024] The cleaning needles 11 are arranged in multiple rows, and the adjacent rows of cleaning needles 11 are staggered. The staggered arrangement of the cleaning needles 11 can improve the coverage effect of cleaning the hot press roller 6.
