Description

Technical Field

[0001] This utility model relates to the field of cardboard technology, specifically to a cardboard surface cleaning device. Background Technology

[0002] Paperboard refers to sheet paper made from plant fibers, a thick sheet of paper composed of interwoven fibers processed from various pulps. The difference between paperboard and regular paper is usually distinguished by basis weight and thickness; generally, paper with a basis weight exceeding 250 g / m² and a thickness greater than 0.5 mm is called paperboard. Before use, paperboard typically needs to have its surface cleaned of debris to improve processing quality.

[0003] A search revealed a Chinese patent application (202122350585.8) disclosing a surface cleaning device for packaging cardboard. This device includes a rotating mechanism, a rotating shaft, a brush disc, and brush bristles. The rotating mechanism is fixedly mounted on a fixed plate and coaxially connected to the rotating shaft. The brush disc is located at the end of the rotating shaft, with its lower surface serving as the working surface. Bristles are located on the lower surface of the brush disc, and these bristles rub against the surface of the packaging cardboard to be cleaned. This invention uses a fixed plate to fix the rotating mechanism on its lower surface. The fixed plate can be flexibly or dynamically fixed depending on the site conditions, ensuring that the bristles can rub against the surface of the material being cleaned. The rotating mechanism drives the rotating shaft to rotate the brush disc, and the bristles clean the surface of the material or packaging cardboard through friction. The device is simple in structure, low in cost, and effective.

[0004] Although the aforementioned patented brush bristles clean the surface of materials or packaging cardboard through friction, and have a simple structure, low cost, and good effect, in actual use they can only clean one side of the cardboard. The cardboard needs to be manually turned over to clean the other side. Moreover, they cannot absorb the dust generated during cleaning, causing dust to splash in the working environment, polluting the environment and causing inconvenience to users.

[0005] Therefore, it needs to be modified to facilitate cleaning of both sides of the cardboard, absorb the dust generated during cleaning, optimize the working environment, and make it more convenient for users. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a cardboard surface cleaning device that can conveniently clean both sides of cardboard, absorb dust generated during cleaning, optimize the working environment, and facilitate user operation. This solves the problems of only being able to clean one side of the cardboard, requiring manual reversal to clean the other side, and the inability to absorb dust generated during cleaning, leading to dust splattering in the working environment, polluting the environment, and causing inconvenience to users.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cardboard surface cleaning device, comprising a base box, a workbench fixedly connected to the top of the base box, a side plate fixedly connected to the left side of the top of the workbench, a top plate fixedly connected to the top of the side plate, a circular groove formed on the surface of the workbench, and a dust collection tray fixedly connected inside the circular groove, the surface of the dust collection tray having a plurality of evenly distributed and vertically penetrating dust collection holes, a dust collection hood connected to the bottom of the dust collection tray, a filter mechanism fixedly connected to the right side of the bottom of the base box, and the left side of the filter mechanism connected to the dust collection hood via a bent pipe. The bottom of the cover is open, and a high-power exhaust fan is fixedly connected to the right side of the top of the workbench. The input end of the high-power exhaust fan passes through to the bottom of the workbench and is connected to the top of the filter mechanism. A drive motor is fixedly connected to the top of the top plate, and the output end of the drive motor passes through to the bottom of the top plate and is fixedly connected to a rotating shaft. The bottom of the rotating shaft is rotatably connected to the top of the dust collection tray. A soft-bristled roller brush is fixedly connected to the surface of the rotating shaft. A driven roller brush that works with the soft-bristled roller brush is rotatably connected to the right side of the bottom of the top plate. The bottom of the driven roller brush is rotatably connected to the top of the dust collection tray.

[0008] As a preferred embodiment of the present invention, the filtration mechanism includes a filter box fixedly connected to the bottom right side of the inner wall of the base box, and slots are fixedly connected to both the left and right sides of the inner wall of the filter box, with polyester fiber filter elements inserted into the slots.

[0009] As a preferred embodiment of this invention, the output end of the high-power exhaust fan is threadedly connected to a secondary filter cover, and the interior of the secondary filter cover is provided with a composite filter paper filter element.

[0010] As a preferred embodiment of this utility model, the left and right sides of the top of the dust collection tray and the left and right sides of the bottom of the top plate are fixedly connected to a limiting plate located between the soft-bristled roller brush and the driven roller brush, and a number of evenly distributed rollers are rotatably connected between the corresponding limiting plates. A number of soft-bristled brushes located above the rollers are fixedly connected to the inner side of the limiting plate.

[0011] As a preferred embodiment of this utility model, T-shaped grooves are provided on both the left and right sides of the bottom of the top plate, and electrostatic adsorption plates are inserted into the interior of the T-shaped grooves.

[0012] As a preferred embodiment of this utility model, the front of the filter box is hinged with a cleaning door, and sealing strips are fixedly connected around the cleaning door, with the surface of the sealing strips fitting against the inner wall of the filter box.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model utilizes a drive motor and a high-power exhaust fan. When the drive motor starts, it rotates the shaft and the soft-bristle roller brush. The cardboard to be cleaned is vertically inserted between the soft-bristle roller brush and the driven roller brush. As the soft-bristle roller brush rotates, it cleans the debris on the left side of the cardboard and moves the cardboard backward. As the cardboard moves backward, the right side rubs against the driven roller brush, cleaning the debris on the right side. When the high-power exhaust fan starts, it creates negative pressure in the filter mechanism and the dust hood, drawing the cleaned debris and dust into the dust hood through the suction hole. The dust then enters the filter mechanism through a curved pipe. The air containing dust is filtered by the filter mechanism and discharged from the output end of the high-power exhaust fan. This achieves convenient cleaning of both sides of the cardboard, absorbing the dust generated during cleaning, optimizing the working environment, and providing convenience for the user.

[0015] 2. This utility model uses a combination of a filter box and a polyester fiber filter element. When a high-power exhaust fan is started and air containing dust and debris enters the filter box, the polyester fiber filter element, with a fiber porosity of 80%-90% and excellent air permeability, can filter particles of 0.3-5μm. This filters most of the dust in the air inside the filter box, purifies the exhaust air, and improves the dust treatment effect. Attached Figure Description

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.

[0022] like Figures 1 to 4 As shown, the present invention provides a cardboard surface cleaning device, including a base box 1, a workbench 2 fixedly connected to the top of the base box 1, a side plate 3 fixedly connected to the left side of the top of the workbench 2, a top plate 4 fixedly connected to the top of the side plate 3, a circular groove formed on the surface of the workbench 2, and a dust collection tray 5 fixedly connected inside the circular groove, a plurality of evenly distributed and vertically penetrating dust collection holes 6 formed on the surface of the dust collection tray 5, a dust collection hood 7 connected to the bottom of the dust collection tray 5, a filter mechanism 8 fixedly connected to the right side of the bottom of the base box 1, and the left side of the filter mechanism 8 connected to the bottom of the dust collection hood 7 via a bent pipe, the workbench 2... A high-power exhaust fan 9 is fixedly connected to the top right side. The input end of the high-power exhaust fan 9 extends through to the bottom of the workbench 2 and communicates with the top of the filter mechanism 8. A drive motor 10 is fixedly connected to the top of the top plate 4. The output end of the drive motor 10 extends through to the bottom of the top plate 4 and is fixedly connected to a rotating shaft 11. The bottom of the rotating shaft 11 is rotatably connected to the top of the dust collection disc 5. A soft-bristled roller brush 12 is fixedly connected to the surface of the rotating shaft 11. A driven roller brush 13, which works in conjunction with the soft-bristled roller brush 12, is rotatably connected to the bottom right side of the top plate 4. The bottom of the driven roller brush 13 is rotatably connected to the top of the dust collection disc 5.

[0023] refer to Figure 2 The filtration mechanism 8 includes a filter box 14 fixedly connected to the bottom right side of the inner wall of the base box 1. Slots are fixedly connected to both the left and right sides of the inner wall of the filter box 14, and polyester fiber filter elements 15 are inserted into the slots.

[0024] As a technical optimization of this utility model, by setting up the filter box 14 and the polyester fiber filter element 15 for use together, when the high-power exhaust fan 9 starts and the air containing dust and debris enters the filter box 14, due to the 80%-90% porosity of the polyester fiber filter element and its excellent air permeability, it can filter 0.3-5μm particles, filtering most of the dust in the air into the filter box 14, purifying the exhaust air and improving the dust treatment effect.

[0025] refer to Figure 1 The output end of the high-power exhaust fan 9 is threadedly connected to a secondary filter cover 16, and a composite filter paper filter element 17 is installed inside the secondary filter cover 16.

[0026] As a technical optimization of this utility model, a secondary filter cover 16 with a threaded connection is provided, and a composite filter paper filter element 17 is set inside the secondary filter cover 16 to perform secondary filtration on the air discharged by the high-power exhaust fan 9, thereby improving the dust treatment effect. At the same time, the composite filter paper filter element 17 can be cleaned or replaced by twisting the secondary filter cover 16 to remove it.

[0027] refer to Figure 4 The top left and right sides of the dust collection plate 5 and the bottom left and right sides of the top plate 4 are fixedly connected to the limiting plates 18 located between the soft brush 12 and the driven brush 13, and a number of evenly distributed rollers 19 are rotatably connected between the corresponding limiting plates 18. A number of soft brushes 20 located above the rollers 19 are fixedly connected to the inner side of the limiting plates 18.

[0028] As a technical optimization of this utility model, by setting the limiting plate 18 and the roller 19, when cleaning the cardboard, the top and bottom of the cardboard are located inside the limiting plate 18 and in contact with the surface of the roller 19, which can fix and limit the cardboard and prevent it from tilting. By setting the soft brush 20, the top and bottom and left and right sides of the cardboard can be cleaned, improving the cleaning effect of the cardboard.

[0029] refer to Figure 1 T-shaped grooves are provided on both the left and right sides of the bottom of the top plate 4, and electrostatic adsorption plates 21 are inserted into the inside of the T-shaped grooves.

[0030] As a technical optimization of this utility model, by setting an electrostatic adsorption plate 21 inserted into the bottom of the top plate 4, the debris splashed to the outside during cardboard cleaning can be adsorbed. At the same time, it is convenient to remove the electrostatic adsorption plate 21 from the bottom of the top plate 4 for cleaning and replacement, which further improves the treatment effect of dust and debris.

[0031] refer to Figure 1The front of the filter box 14 is hinged with a cleaning door 22. The cleaning door 22 is fixedly connected with sealing strips 23 around its perimeter. The surface of the sealing strips 23 is in contact with the inner wall of the filter box 14.

[0032] As a technical optimization of this utility model, by setting a cleaning door 22, the dust and debris remaining inside the filter box 14 can be easily cleaned by opening the cleaning door 22, and the polyester fiber filter element 15 can be disassembled, cleaned and replaced. By setting a sealing strip 23, the gap between the cleaning door 22 and the filter box 14 is sealed, avoiding air leakage in the gap and affecting the dust collection effect of the high-power exhaust fan 9.

[0033] The working principle and usage process of this utility model are as follows: By starting the drive motor 10 and the high-power exhaust fan 9, the drive motor 10 drives the rotating shaft 11 and the soft-bristle roller brush 12 to rotate. The cardboard to be cleaned is vertically inserted between the soft-bristle roller brush 12 and the driven roller brush 13. When the soft-bristle roller brush 12 rotates, it cleans the debris on the left side of the cardboard and moves the cardboard backward. When the cardboard moves backward, the right side rubs against the driven roller brush 13, cleaning the debris on the right side. When the high-power exhaust fan 9 starts, it creates a negative pressure in the filter mechanism 8 and the dust hood 7, sucking the cleaned debris and dust into the dust hood 7 through the dust suction hole 6, and then into the filter mechanism 8 through the curved pipe. The air containing dust is filtered by the filter mechanism 8 and discharged from the output end of the high-power exhaust fan 9. This achieves the effect of conveniently cleaning both sides of the cardboard, absorbing the dust generated by the paper scraps during cleaning, optimizing the working environment, and making it convenient for users.
