Description

Technical Field

[0001] This utility model relates to the field of papermaking production technology, specifically a papermaking production line with a dust-collecting structure. Background Technology

[0002] Papermaking refers to the production of paper. It usually involves diluting pulp suitable for paper quality with water to a certain concentration, initially dewatering it on the wire section of a paper machine to form a wet sheet, and then processing it into paper through a series of other manufacturing processes. Paper production involves many steps and requires the use of machine production lines to manufacture paper. Machine production lines play a very important role in the papermaking process.

[0003] Existing paper production lines include paper slitting. During slitting, paper dust or fiber debris is generated near the paper. If this dust is not treated, it will escape into the surrounding air and reduce environmental quality. Utility Model Content

[0031] (III) Beneficial Effects

[0032] Compared with the prior art, this utility model provides a papermaking production line with a dust-collecting structure, which has the following beneficial effects:

[0033] This production line features convenient dust collection. When the slitting mechanism cuts paper, the controller activates the suction pump and motor. The suction pump draws air out of the collection box, creating negative pressure. The dust-laden air is then drawn into the air supply pipe by the suction head. Once inside the collection box, the dust-laden air is filtered by a filter. The filtered air is then discharged by the suction pump. The motor, upon starting, drives a rotating shaft. The brushes on the shaft clean the dust adhering to the filter screen, preventing dust accumulation and ensuring effective dust collection. This solves the problem in existing paper production lines where the dust generated during paper slitting can negatively impact the surrounding working environment if not properly managed.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Example 1

[0045] See Figure 1-5 A paper production line with a dust-collecting structure includes a main component 1, which includes: a conveyor belt 11 with support plates 12 on both sides; a bracket 13 fixedly connected to the top of the support plates 12; a slitting mechanism 14 disposed on the bracket 13; a dust-collecting component 2 disposed on the support plates 12 and the bracket 13, the dust-collecting component 2 including: an air supply pipe 21 penetratingly connected to the bracket 13; a dust collection head 211 disposed on the air supply pipe 21; a collection box 22 fixedly connected to the outer wall of the support plate 12, the bottom end of the air supply pipe 21 penetrating and extending into the inside of the collection box 22; and a filter screen 23 disposed in the collection box 22. The filter 23 has the following components: an inner wall; an air pump 24, located on the outer wall of the collection box 22, with its input end extending through and into the collection box 22; a rotating shaft 25, which passes through and is rotatably connected to the collection box 22; a brush plate 26, fixedly connected to one end of the rotating shaft 25 located inside the collection box 22, and slidably connected to the outer wall of the filter screen 23; a motor 27, located on the outer wall of the collection box 22, with its output shaft fixedly connected to one end of the rotating shaft 25; and a controller 271, located on the outer wall of the collection box 22, electrically connected to the air pump 24 and the motor 27 of the cutting mechanism 14. A sealing element 4 is provided at the connection between the collection box 22 and the rotating shaft 25. Multiple suction heads 211 are symmetrically arranged.

[0046] During use, the conveyor belt 11 transports the paper to be cut to the area below the support 13. The paper is then cut by the cutting mechanism 14. At this time, the operator controls the air pump 24 and motor 27 to start via the controller 271. After the air pump 24 starts, it draws out the air inside the collection box 22, creating a negative pressure inside the collection box 22. The dust mixed with air generated during the cutting by the cutting mechanism 14 is sucked into the air supply pipe 21 by the dust suction head 211. After the dust-laden air enters the collection box 22, the filter screen 23 filters the dust. The filtered air is discharged by the air pump 24. After the motor 27 starts, it drives the rotating shaft 25 to rotate. The brush plate 26 on the rotating shaft 25 rotates to clean the dust adhering to the surface of the filter screen 23, thereby preventing dust from accumulating on the filter screen 23 and affecting the normal dust collection effect. When the motor 27 drives the rotating shaft 25 to rotate, the seal 4 maintains the seal at the connection between the rotating shaft 25 and the collection box 22. The seal 4 consists of a rotating ring, a stationary ring, a spring, and other components. The rotating ring rotates synchronously with the rotating shaft 25, and the stationary ring is fixed on the collection box 22, forming a tight sealing surface between them. The spring provides elasticity, keeping the rotating ring and the stationary ring in contact at all times, thereby achieving a seal. The multiple suction heads 211 increase the suction area, thereby enhancing the suction effect.

[0047] The aforementioned slitting mechanism 14 employs conventional technology, such as a feed guide roller that guides the paper to the bottom of a circular blade, which then slits the paper. As long as the paper can be slit, the specific structure will not be described in detail here.

[0048] Example 2

[0049] An auxiliary function has been added based on Embodiment 1.

[0050] See Figure 1-5 The collection box 22 and the controller 271 are equipped with a backflushing assembly 3. The backflushing assembly 3 includes: an air pipe 31, located inside the collection box 22, with its top input end extending through and to the outside of the collection box 22; a nozzle 32, obliquely disposed on the outer wall of the air pipe 31; an air compressor 35, located on the top of the collection box 22, electrically connected to the controller 271; an air tank 34, located at the output end of the air compressor 35, with its input end connected to the top of the air pipe 31; and a pulse valve 33, located at the connection between the air pipe 31 and the air tank 34, electrically connected to the controller 271. Multiple nozzles 32 are symmetrically arranged around the circumference. A collection frame with an inclined surface is provided at the bottom of the collection box 22.

[0051] The operator starts the air compressor 35 via controller 271, which generates compressed air. This compressed air is stored in the air tank 34. Controller 271 periodically controls the pulse valve 33 to open, allowing compressed air to flow into the ventilation pipe 31. The nozzles 32 guide the compressed air to the surface of the filter screen 23, backflushing out dust clogging the filter pores. The backflushing assembly 3 works in conjunction with the brush plate 26 to prevent clogging of the filter screen 23, thus enhancing the dust collection effect. Multiple nozzles 32 are evenly distributed circumferentially along the ventilation pipe 31, allowing for simultaneous airflow and increased coverage. Each annular nozzle 32 corresponds to a different sector of the filter screen 23, distributing the total pressure across multiple points of action, reducing single-point impact while maintaining overall cleaning power. The dust filtered by the filter screen 23 slides along an inclined surface into a collection frame at the bottom of the collection box 22 for easy subsequent cleaning.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
