Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a dust removal device for paper product processing. Background Art

[0002] Paper product processing is an important industrial process with wide applications, covering multiple fields such as books, packaging materials, and toilet paper. During the processing, a large amount of dust and fiber debris are generated due to operations such as paper cutting, grinding, and handling. These dusts not only affect the cleanliness of the production environment and the health of operators, but also may affect product quality and production efficiency. Therefore, dust removal equipment is particularly important in paper product processing.

[0003] The existing dust removal devices for paper product processing usually use a single fixed suction port to handle the dust and fiber debris inside the paper product processing device, keeping the production facilities clean, thereby improving the work efficiency and production quality of the staff. And it helps to reduce the dust concentration in the air, reduce the potential impact on employees' health, and create a safer and more comfortable working environment. In addition, an appropriate dust removal system can also extend the service life of equipment and machines, reduce maintenance costs, and save resources and operating expenses for enterprises.

[0004] However, the single fixed suction port in the existing technology cannot flexibly adapt to different processing equipment, resulting in ineffective removal of some dusts, affecting the cleaning effect and the cleanliness of the working environment. Secondly, the position of the fixed suction port limits its ability to adapt to different processing stages and different paper sizes, and manual adjustment or a combination of multiple suction ports may be required to achieve the ideal dust removal effect. In addition, since the operator cannot adjust the position of the suction port in time, new dust accumulation points may appear during the processing, thus affecting the long-term performance and maintenance requirements of the equipment. For this reason, a dust removal device for paper product processing is proposed to solve the above problems. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Refer to Figure 2 - Figure 4, an embodiment provided by the present utility model: a dust removal device for paper product processing, including a support frame 1, an outer housing one 2 fixedly connected to the inner wall of the support frame 1, an exhaust pipe 3 fixedly connected to the top of the outer housing one 2, a valve 8 fixedly connected to the bottom of the outer housing one 2, an outer housing two 35 fixedly connected to one side of the outer wall of the outer housing one 2, a motor two 5 fixedly connected to the top of the outer housing two 35, a worm one 12 fixedly connected to the output end of the motor two 5, a motor one 4 fixedly connected to the top of the outer housing two 35, a worm two 14 fixedly connected to the output end of the motor one 4, a rotating column 13 rotatably connected to one side of the outer wall of the outer housing one 2, a worm gear one 15 fixedly connected to the outer wall of the rotating column 13, the outer wall of the worm gear one 15 meshing with the outer wall of the worm one 12, a bevel gear one 18 fixedly connected to one end of the rotating column 13, a rotating cylinder 33 rotatably connected to the outer wall of the rotating column 13, a worm gear two 16 fixedly connected to the outer wall of the rotating cylinder 33, the outer wall of the worm gear two 16 meshing with the outer wall of the worm two 14, a disk 17 fixedly connected to one end of the rotating cylinder 33, the inside of the disk 17 rotatably connected to the outer wall of the rotating column 13, two symmetrically arranged fixing blocks 19 fixedly connected to one side of the outer wall of the disk 17, a rotating rod 21 rotatably connected to the inside of the fixing blocks 19, a bevel gear two 20 fixedly connected to the outer wall of the rotating rod 21, the outer wall of the bevel gear two 20 meshing with the outer wall of the bevel gear one 18, a fixing frame 22 fixedly connected to the outer wall of the rotating rod 21, a cylinder 23 fixedly connected to one side of the outer wall of the fixing frame 22, a connecting rod 34 fixedly connected to the output end of the cylinder 23, two symmetrically arranged moving blocks 24 rotatably connected to the inside of the connecting rod 34, one side of the outer wall of the moving blocks 24 rotatably connected to the inner wall of the fixing frame 22, an arc-shaped clamping block 25 rotatably connected to the inside of the moving blocks 24, a dust suction assembly is arranged inside the outer housing one 2, and the dust suction assembly is used for sucking dust during paper product processing;

[0034] Specifically, the motor two 5 drives the worm one 12 to rotate, the outer wall of the worm one 12 meshes with the worm gear one 15, pushing the worm gear one 15 to rotate, and further driving the rotating column 13 and the bevel gear one 18 to rotate. At the same time, the bevel gear one 18 meshes with the bevel gear two 20, causing the bevel gear two 20 and the rotating rod 21 to rotate, further driving the fixing frame 22 to rotate. The clamping assembly on the fixing frame 22 can adjust the angle in the vertical direction to meet the dust removal requirements of different paper product processing equipment. In addition, the motor one 4 drives the worm two 14 to rotate, the outer wall of the worm two 14 meshes with the worm gear two 16, pushing the worm gear two 16 and the rotating cylinder 33 to rotate. The fixed disk 17 on the rotating cylinder 33 rotates the clamping assembly to ensure that the dust suction air pipe 6 can be effectively clamped. The telescopic movement of the cylinder 23 causes the connecting rod 34 to drive the moving blocks 24 to contract or expand, further adjusting the opening and closing state of the arc-shaped clamping block 25 to ensure the stable clamping of the dust suction air pipe 6. This design not only improves the operation accuracy and stability of the device, but also effectively reduces the requirements for equipment maintenance and adjustment, providing a reliable guarantee for efficient dust removal during the paper product processing process.

[0035] Refer to Figure 1, the dust collection component includes a dust collection air pipe 6 and a vacuum cleaner 7. The outer wall of the dust collection air pipe 6 is fixedly connected inside the first housing 2, and one side of the outer wall of the vacuum cleaner 7 is fixedly connected to one end of the dust collection air pipe 6;

[0036] Specifically, after accurately aligning the vacuum cleaner 7, start the vacuum cleaner 7 to strongly suck dust inside the device. After the dust is processed by the highly efficient filter cartridge 10 filtration system, it ensures that the air discharged from the exhaust pipe 3 is clean and dust-free. This highly efficient dust removal process can not only quickly remove dust in the target area, but also effectively improve the cleanliness and work efficiency of the production environment.

[0037] Refer to Figure 2 and Figure 5 , a fixing strip 11 is fixedly connected to the inner wall of the first housing 2. The bottom of the fixing strip 11 is fixedly connected to a filter cartridge 10. A plate-shaped cleaning brush 9 is slidably connected to the outer wall of the filter cartridge 10. A chute block 28 is fixedly connected to the inner wall of the first housing 2. Symmetrically arranged left and right limiting columns 36 are fixedly connected to the inner wall of the first housing 2. The outer walls of the limiting columns 36 are slidably connected to the inner wall of the plate-shaped cleaning brush 9. A slider 29 is slidably connected to the inner wall of the chute block 28. A sliding rod 30 is fixedly connected to the inner wall of the chute block 28. The outer wall of the exhaust pipe 3 is slidably connected to the inner wall of the slider 29. The outer wall of the sliding rod 30 is slidably connected to a first spring 31. One end of the first spring 31 is fixedly connected to the bottom of the slider 29, and the other end of the first spring 31 is fixedly connected to the bottom of the inner wall of the chute block 28. One side of the outer wall of the slider 29 is fixedly connected to a sleeve 32. A second spring 37 is slidably connected to the inner wall of the sleeve 32. One end of the second spring 37 is fixedly connected to the inner wall of the sleeve 32, and the other end of the second spring 37 is fixedly connected to a cutter 38. A connecting block 39 is fixedly connected to the top of the sleeve 32. One side of the bottom of the connecting block 39 is fixedly connected to a third motor 26. The output end of the third motor 26 is fixedly connected to a cylinder 27. One side of the outer wall of the cylinder 27 is rotatably connected to one side of the cutter 38. One side of the outer wall of the sleeve 32 is fixedly connected to one side of the outer wall of the plate-shaped cleaning brush 9;

[0038] Specifically, the third motor 26 drives the cylinder 27 to rotate. The outer wall of the cylinder 27 is designed with a structure meshing with the cutter 38, so that the cutter 38 moves downward as the cylinder 27 rotates, and then pushes the sleeve 32 and the slider 29 to slide downward inside the chute block 28. At the same time, the sleeve 32 maintains a stable pressure by compressing the second spring 37 to ensure that the cutter 38 can move effectively in different working stages in the arc-shaped groove and straight-shaped groove of the cylinder 27. When the cutter 38 reaches the bottom of the cylinder 27, due to the upward reaction force generated by the compressed first spring 31, the slider 29 can quickly move upward, realizing the reciprocating sliding of the plate-shaped cleaning brush 9 on the outer wall of the filter cartridge 10, and thoroughly removing the dust adhering to the surface of the filter cartridge 10. This design not only improves the cleaning efficiency and accuracy, but also greatly reduces the equipment maintenance cycle and downtime, ensuring the long-term stable performance of the device, thus providing reliable support for efficient operation in the production process.

[0039] Working principle: First, the motor 5 drives the worm 12 to rotate. Since the outer wall of the worm 12 meshes with the outer wall of the worm gear 15, the rotation of the worm 12 drives the worm gear 15 to rotate, thereby driving the rotating column 13 to rotate, further driving the bevel gear 18 to rotate. And since the outer wall of the bevel gear 20 meshes with the outer wall of the bevel gear 18, the rotation of the bevel gear 18 drives the bevel gear 20 to rotate, thereby driving the rotating rod 21 to rotate, further driving the fixed frame 22 to rotate. A clamping assembly is fixed on one side of the fixed frame 22, thereby driving the angle adjustment of the clamping assembly in the vertical direction. Then, the motor 1 4 drives the worm 2 14 to rotate. Since the outer wall of the worm 2 14 meshes with the outer wall of the worm gear 2 16, the rotation of the worm 2 14 drives the worm gear 2 16 to rotate, thereby driving the rotating cylinder 33 to rotate. And a disk 17 is fixed on one side of the rotating cylinder 33, further driving the disk 17 to rotate. The clamping assembly is fixed on the outer wall of the disk 17, thereby driving the clamping assembly to rotate to adapt to the dust removal requirements of different paper product processing equipment. Furthermore, the cylinder 23 performs a contraction movement, driving the connecting rod 34 to move to the left. An elliptical hole is provided inside the connecting rod 34. The movement of the connecting rod 34 to the left causes the moving block 24 to move and contract on the inner wall of the hole. And since the outer wall of the moving block 24 is fixed to the outer wall of the fixed frame 22, the other side of the moving block 24 expands, thereby driving the arc-shaped clamping block 25 to expand. Place the dust suction pipe 6 inside the arc-shaped clamping block 25, and then the cylinder 23 extends, causing the arc-shaped clamping block 25 to contract, thereby completing the clamping of the dust suction pipe 6. Align the vacuum cleaner 7 with the position to be dusted, start the vacuum cleaner 7 to suck the dust into the device, and discharge it from the exhaust pipe 3 after being filtered by the filter cartridge 10. When the dust removal is completed, open the valve 8, and the treated dust is discharged from the valve 8. Collect the dust and then conduct centralized treatment. If the inside of the device needs to be cleaned, mainly the outer wall of the filter cartridge 10 is cleaned. First, the motor 3 26 drives the cylinder body 27 to rotate. Since the outer wall of the cutter 38 meshes with the outer wall of the cylinder body 27, the rotation of the cylinder body 27 drives the cutter 38 to move downward, thereby driving the sleeve 32 to move downward, further driving the slider 29 to slide downward on the inner wall of the chute block 28. At the same time, the slider 29 compresses the spring 1 31 downward. The outer wall of the cylinder body 27 is provided with an arc-shaped groove and a straight groove. When the cutter 38 moves to the bottom of the cylinder body 27, there is a vertical straight groove. Since the spring 1 31 is compressed, at this time, an upward pressure acts on the bottom of the slider 29, causing the slider 29 to move upward. In this way, reciprocatingly, the plate-shaped cleaning brush 9 is driven to slide up and down on the outer wall of the filter cartridge 10 to complete the cleaning of the dust attached to the surface of the filter cartridge 10.
