Description

Technical Field

[0001] This application relates to the technical field of board cleaning, and in particular to a board cleaning device. Background Technology

[0002] Sandwich panels are a type of composite sandwich panel made by bonding a lightweight, insulated core panel to two high-strength panels. They are lightweight and have good thermal insulation properties, and are widely used in the construction and vehicle industries.

[0003] The core board is mainly made of XPS, EPS and PET. After cutting or grinding, its surface will be covered with dust and debris. If these impurities are not cleaned or are not cleaned thoroughly, they will affect the strength when bonding the panels later. Manually using a high-pressure air gun to blow away the impurities on the surface of the core board is inefficient and labor-intensive. In addition, the dust blown away seriously pollutes the production environment and endangers health.

[0004] In the prior art, Chinese Patent No. CN215142875U discloses a dust removal device for sheet metal, including a dust removal frame and two dust removal components arranged above and below the dust removal frame. A dust removal gap is formed between the two dust removal components, and the distance between the two dust removal components can be adjusted. The sheet metal passes through the dust removal gap, and the two dust removal components clean the dust on the upper and lower surfaces of the sheet metal. The dust removal components can perform blowing and suction operations simultaneously. The dust removal components can blow away the dust on the surface of the sheet metal and suck away the dust on the surface of the sheet metal and the dust in the air.

[0005] However, the dust removal device is open-set, with the dust removal components and the plates exposed to the external environment. High-speed airflow can cause some dust to spread from the dust removal gaps into the external environment, causing pollution. Furthermore, the spacing between the dust removal components needs to be frequently adjusted according to the thickness of the plates, which is inconvenient to use. In addition, the equipment has a complex structure and high manufacturing and maintenance costs. Utility Model Content

[0006] This application provides a board cleaning device that can at least partially solve the above-mentioned technical problems.

[0007] This application provides a board cleaning device, which adopts the following technical solution:

[0008] A board cleaning device, comprising:

[0009] The dust removal chamber has an inlet and an outlet on opposite sides.

[0010] The dust blowing assembly includes at least one set of dust blowing units disposed near the discharge port for spraying airflow onto the surface of the sheet material passing through the discharge port;

[0011] A dust extraction component, connected to the dust removal chamber, is used to extract dust from the chamber.

[0012] A guiding assembly, disposed within the dust removal chamber, includes a guide member located between the inlet and outlet for supporting the sheet material.

[0013] By adopting the above technical solution, the sheet enters the closed dust removal chamber from the feed inlet. When the sheet is pushed along the guide gap to the discharge port, the dust blowing unit sprays high-speed airflow onto the surface of the sheet to remove dust. The dust suction component continuously sucks up the dust in the dust removal chamber, and the closed dust removal chamber prevents the dust from spreading and improves the working environment. The dust blowing component is located near the discharge port to avoid secondary contamination of the cleaned sheet. It is adaptable to sheets of different thicknesses (without the need for frequent adjustment of equipment spacing), and the guide component ensures that the sheet passes stably through the core cleaning area.

[0014] Optionally, the dust blowing unit includes:

[0015] The air inlet pipe is closed at one end and connected to the air source at the other end, and an air outlet groove is provided on the side near the discharge port.

[0016] The air outlet is connected to the air outlet groove, and its cross-section gradually narrows from the air inlet to the air outlet.

[0017] By adopting the above technical solution, the airflow enters the gradually narrowing air outlet from the air inlet pipe through the air outlet groove, and the high-speed airflow is ejected from the gradually narrowing air outlet, which enhances the dust removal effect.

[0018] Optionally, the air outlet extends into the discharge port.

[0019] By adopting the above technical solution, the air outlet extends into the discharge port, and the airflow directly acts on the surface of the board; the dust is blown into the dust removal chamber to prevent it from escaping into the external environment.

[0020] Optionally, the air outlet is a slit structure, and two sets of dust blowing units are provided, with their main bodies respectively located on the upper and lower sides of the outer edge of the outlet.

[0021] By adopting the above technical solution, the air outlet adopts a slit structure. The gradually narrowing slit structure utilizes the narrow tube effect to increase the airflow speed, spray high-speed airflow, and enhance the dust removal effect. The upper and lower dust blowing units simultaneously clean both sides of the board, achieving efficient dust removal on both sides and eliminating cleaning blind spots.

[0022] Optionally, it also includes:

[0023] A movable baffle is rotatably connected to the upper edge of the feed inlet; when no sheet material is being conveyed, the movable baffle seals the feed inlet; when sheet material is being conveyed, the movable baffle rests against the upper surface of the sheet material to form a dynamic seal.

[0024] By adopting the above technical solution, the sheet material enters the closed dust removal chamber from the feed inlet, and the movable baffle automatically adheres to the upper surface of the sheet material under its own weight to form a dynamic seal; the movable baffle adaptively seals the feed inlet, adapts to sheet materials of different thicknesses, and can achieve a sealing effect for sheet materials of various specifications and thicknesses.

[0025] Optionally, the guide members are provided in two sets, and the two sets of guide members are arranged opposite each other to form a guide gap for the plate to pass through;

[0026] The guiding component also includes:

[0027] The first guide plate, located on the left and right sides inside the dust removal chamber, connects the inlet and outlet and is used to limit the lateral displacement of the plate.

[0028] By adopting the above technical solution, the two sets of guide members form a guide gap for the plate to pass through. The guide gap constrains the plate, reducing the possibility of the plate tip lifting during the conveying process and reducing the vertical displacement of the plate, so that the plate slides stably. The first guide plate is set along the left and right side walls of the dust removal chamber to constrain the lateral displacement of the plate during the conveying process. This prevents the plate from deviating and causing jamming or collision, and ensures that it passes through the dust blowing area along the predetermined path.

[0029] Optionally, the guide component further includes:

[0030] A second guide plate, which is located inside the discharge port and is arranged in an arc shape, is used to guide the sheet material when it enters the discharge port; a third guide plate, which is located outside the feed port and is arranged in an arc shape, is used to guide the sheet material when it enters the feed port.

[0031] By adopting the above technical solution, the third guide plate guides the plate in an arc shape at the inlet, forming a double-end guide for both inlet and outlet with the second guide plate; the arc-shaped second guide plate elastically presses against the edge of the plate at the outlet, guiding it to be output smoothly; the elastic design adapts to plates of different widths, reduces discharge skew, and improves discharge smoothness; the dual optimization of the inlet and outlet paths reduces the plate conveying resistance, improves continuity, and allows the plate to move within the set area, thereby improving the dust removal effect.

[0032] Optionally, the guide component further includes:

[0033] A flared, funnel-shaped opening is provided outside the feed inlet;

[0034] or,

[0035] Guide rollers located at the outer edge of the feed inlet.

[0036] By adopting the above technical solution, the flared part guides the plate to accurately enter the feed port; the guide roller rolls and supports the plate at the outer edge of the feed port, reducing frictional resistance; the flared part reduces the difficulty of feeding and positioning, and improves efficiency; the guide roller reduces the friction damage to the plate surface between the plate and the edge of the feed port, thus reducing plate damage.

[0037] Optionally, the top plate of the dust removal chamber can be opened, and a sealing strip is provided at the connection between the top plate and the side plate.

[0038] By adopting the above technical solution, the top plate can be opened to clean the inside of the dust removal chamber during maintenance; the sealing strip ensures the airtightness of the chamber when closed, facilitating equipment maintenance; and the sealing strip ensures zero dust leakage during operation.

[0039] Optionally, the bottom of the dust removal chamber is provided with a dust guiding chamber, the internal space of the dust guiding chamber gradually narrows from top to bottom, and a through hole is opened at the bottom to connect to the dust collection component.

[0040] By adopting the above technical solution, dust falls into the narrowed dust guide chamber under gravity and is concentrated and sucked up by the dust collection component through the through hole; the narrowed structure accelerates dust accumulation and improves dust collection efficiency; and reduces dust accumulation at the bottom of the dust collection chamber.

[0041] In summary, this application includes at least one of the following beneficial technical effects:

[0042] 1. The dust blowing component is located near the discharge port to reduce secondary pollution to the cleaned board. The dust is prevented from spreading by the closed dust removal chamber, the dynamic sealing of the movable baffle, the dust removal component, and the air outlet extending to the discharge port.

[0043] 2. The air outlet is designed with a slit structure, which can obtain a higher outlet air velocity by utilizing the narrow tube effect, thereby improving the cleaning quality. The dust removal chamber is connected to a dust guide chamber with a gradually narrowing interior. The dust collection component is placed below the dust guide chamber, and the dust can be better sucked away under the action of gravity and negative pressure.

[0044] 3. The distance between the inlet and outlet is fixed, and a movable baffle is used for sealing, which can adapt to the cleaning needs of different thickness plates under this distance. Attached Figure Description

Detailed Implementation

[0058] The following combination Figures 1 to 12 This application will be described in further detail.

[0059] This embodiment discloses a board cleaning device.

[0060] Example 1: Refer to Figures 1 to 8 The board cleaning equipment includes a dust removal chamber 100, a dust blowing component 200, a dust suction component 300, and a guide component 400.

[0061] The dust removal chamber 100 is a closed cavity composed of four side plates 140, a top plate 130 and a bottom plate 150. The top plate 130 is located on top of the side plates 140 and the bottom plate 150 is located at the bottom of the side plates 140. The side plates 140 are surrounded by two first side plates 141 and two second side plates 142. The two opposite and parallel first side plates 141 are respectively provided with a feed inlet 110 and a discharge outlet 120. The bottom plate 150 is provided with a first through hole 151.

[0062] The dust blowing assembly 200 includes two dust blowing units located near the discharge port 120. The two dust blowing units are respectively located at the upper and lower parts of the discharge port 120. Each dust blowing unit includes an air inlet pipe 210 and an air outlet 220.

[0063] One end of the air inlet pipe 210 is closed, and the other end is open. The open end of the air inlet pipe 210 is connected to an air source, such as a blower (existing technology, not shown in the figure). An air outlet groove 211 is provided on the side of the air inlet pipe 210 near the discharge port 120. The air outlet 220 is connected to the air outlet groove 211. It is a hollow structure composed of four thin plates, with an air inlet 221 and an air outlet 222. The air outlet gradually narrows from the air inlet 221 to the air outlet 222. The air entering the air inlet pipe 210 flows out from the air outlet groove 211 and is further blown out from the air outlet 222 of the air outlet 220. The air outlet 222 is a slit structure. By utilizing the slit effect, a higher outlet air velocity can be obtained, which improves the cleaning effect. In addition, placing the dust blowing component 200 near the discharge port 120 can prevent the cleaned surface from being contaminated by dust again, resulting in a better cleaning effect.

[0064] In other embodiments, the air outlet 222 may be a row of spaced-apart round holes, elongated holes or other hole-like structures of any shape, or may be multiple nozzles disposed on the air inlet pipe 210. The nozzles may be flat or tapered with gradually decreasing diameter to facilitate obtaining a higher outlet air velocity.

[0065] The vacuuming assembly 300 includes a vacuum cleaner 310 and a connecting pipe 320. The vacuum cleaner 310 is connected to a through hole on the bottom plate 150 of the dust removal chamber 100 through the connecting pipe 320, thereby communicating with the dust removal chamber 100 and sucking away the dust in the dust removal chamber 100.

[0066] The guide assembly 400 includes a guide member 410, which may be a guide roller, a mesh frame structure, a guide rod, or other support structure with gaps. In this embodiment, a guide rod is preferred. The guide rod is located between the feed inlet 110 and the discharge outlet 120 and is used to support and guide the sheet material.

[0067] Preferably, the guide assembly 400 also includes a first guide plate 440. The two first guide plates 440 are respectively disposed on the left and right sides inside the dust removal chamber 100 and connected to the inlet 110 and the outlet 120, which can prevent the plate from being unable to be smoothly discharged from the outlet 120 due to lateral position displacement during the conveying process.

[0068] Preferably, the two dust blowing units are located on the upper and lower sides of the outer edge of the discharge port 120, and the air outlet 222 of the air nozzle 220 extends into the discharge port 120. This arrangement can ensure that the blown dust is located in the dust removal chamber 100 to the greatest extent possible, thus avoiding pollution to the external environment.

[0069] Preferably, the guide member 410 includes two sets, upper and lower, each set including 3 guide rods. A guide gap 411 is formed between the two sets of guide members 410 to allow the plate to pass through, which can better guide the plate. The air outlet 222 is located outside the guide gap 411, thereby avoiding interference between the plate and the air outlet 220 during the plate conveying process. The height of the bottom set of guide members 410 is higher than the height of the air outlet 220 on the lower side of the discharge port 120, reducing the collision between the plate movement and the air outlet 220.

[0070] Preferably, a movable baffle 500 is provided on the inner side of the first side plate 141. The movable baffle 500 is rotatably connected to the upper edge of the feed inlet 110 by a hinge, and its size is slightly larger than that of the feed inlet 110. When there is no sheet material being conveyed, the movable baffle 500 rests against the inner wall of the first side plate 141 to seal the feed inlet 110. When there is sheet material being conveyed, the movable baffle 500 will rest against the upper surface of the sheet material under its own weight, thereby preventing dust from flowing out of the feed inlet 110 to the greatest extent.

[0071] Preferably, the feed inlet 110 is also connected to a flared part 420 with a horn structure, which facilitates the guidance of the plate material to be easily connected to the feed inlet 110.

[0072] Preferably, the top plate 130 can be opened to facilitate maintenance of the dust removal chamber 100. A sealing strip is provided at the connection between the top plate 130 and the side plate 140 to enhance the sealing of the dust removal chamber 100. The bottom plate 150 is provided with four support legs 600, and the dust removal chamber 100 is supported on the four support legs 600.

[0073] As a further preferred option, the four side plates 140 of the dust removal chamber 100 are directly welded to the four longitudinally arranged support legs 600, and several reinforcing pipes are also provided between the four support legs 600. The two ends of the guide rod 410 are respectively welded to the corresponding reinforcing pipes.

[0074] Example 2: Refer to Figures 9 to 12The similarities with Embodiment 1 will not be repeated here. The difference is that in this embodiment, the bottom plate 150 is not provided at the bottom of the dust removal chamber 100. Instead, a dust guiding chamber 160 with a gradually narrowing interior is provided. A second through hole 161 is provided at the bottom of the dust guiding chamber 160. A connecting pipe 320 is connected to the second through hole 161. The connecting pipe 320 is used to connect an external vacuum cleaner 310 (existing technology, not shown in the figure). The dust guiding chamber 160 can prevent dust from accumulating in the dust removal chamber 100 and further improve the dust removal effect.

[0075] The guide assembly 400 includes a second guide plate 450 and a third guide plate 460. The second guide plate 450 is disposed at both ends of the inner edge of the discharge port 120. The second guide plate 450 is an elastic arc-shaped plate. The second guide plate 450 can guide the material when it is about to enter the discharge port 120. Due to its elasticity, the second guide plate 450 can achieve adaptive guidance of the material width within a certain range. The third guide plate 460 is disposed at both ends of the outer edge of the feed port 110. The third guide plate 460 is an arc-shaped plate. It can guide the material when it enters the feed port 110.

[0076] Preferably, the guide assembly 400 also includes a guide roller 430, which is rotatably connected to the upper and lower sides of the outer edge of the feed inlet 110 via an L-shaped bracket. The guide roller 430 can help the plate enter the feed inlet 110 more smoothly and prevent the plate from being damaged by friction with the edge of the feed inlet 110. When using the guide roller 430, the flared part 420 of the horn structure needs to be replaced.

[0077] Preferably, the connecting tube 320 is a flexible tube, which makes the connection of the vacuum cleaner 310 more flexible and facilitates the installation and maintenance of the vacuum cleaner 310.

[0078] Working principle: Start the blower and vacuum cleaner 310 to feed the board into the guide gap 411 from the feed port 110 and continue to push the board to the discharge port 120 area. The high-speed airflow generated by the dust blowing component 200 cleans the surface of the board and finally sends it out from the discharge port 120. The blown dust will be confined in the dust removal chamber 100 and fall into the dust guiding chamber 160, and finally sucked away by the vacuum cleaner 310 through the connecting pipe 320.

[0079] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
