Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a cleaning device for the production of insulation boards. Background Technology

[0002] During the cutting, transportation, and subsequent processing of insulation boards, dust, debris, and other contaminants easily adhere to their surface. To prevent these contaminants from affecting the subsequent packaging, bonding, or construction quality of the insulation boards, they typically need to be cleaned during the production process.

[0003] Existing insulation board cleaning equipment typically uses rotating brushes to sweep the surface of the insulation board, combined with a negative pressure dust collection device to collect the dust generated during the sweeping process. However, conventional cleaning equipment usually has two brush rollers, one above the other, to sweep the surface of the insulation board. But insulation boards are typically several centimeters to over ten centimeters thick, with multiple surfaces to be cleaned, including the top, bottom, and sides. The distribution of brush rollers in existing equipment often makes it difficult to cover all the surfaces of the insulation board. In addition, conventional brush rollers usually only rotate around their own axis, and the contact trajectory between the bristles and the insulation board surface is relatively fixed. This easily leads to repeated sweeping of the same area while some areas are not cleaned thoroughly. It is particularly difficult to effectively clean dust and debris located between adjacent sweeping trajectories or in local uneven areas of the insulation board, affecting the cleaning quality of the insulation board. Summary of the Invention

[0004] This application aims to at least partially address one of the technical problems in the related art.

[0005] Therefore, the purpose of this application is to provide a cleaning device for the production of insulation boards, which is equipped with two first cleaning units and two second cleaning units to thoroughly clean multiple surfaces of the insulation boards, and improves the cleaning effect by making the horizontal brush roller reciprocate axially when rotating, so that the bristles of the horizontal brush roller can clean the surface of the insulation board with a composite motion trajectory.

[0006] To achieve the above objectives, this application provides a cleaning device for insulation board production, comprising a cleaning hood, two first cleaning units for cleaning the top and bottom surfaces of the insulation board respectively, two second cleaning units for cleaning the sides of the insulation board respectively, and a dust collection mechanism. The first cleaning unit includes two parallel horizontal brush rollers and a first driving mechanism. The first driving mechanism drives the two horizontal brush rollers to rotate and reciprocate along their own axial direction to clean the top and bottom surfaces of the insulation board. The two horizontal brush rollers are arranged to rotate in opposite directions to allow dirt to accumulate between them. The second cleaning unit includes a vertical brush roller and a second driving mechanism for driving the vertical brush roller to rotate. The cleaning hood has an inlet for the insulation board to pass through. Both the horizontal and vertical brush rollers are disposed inside the cleaning hood. A flow equalization chamber is provided at the upper and lower parts of the cleaning hood, and the horizontal and vertical brush rollers are located between the two flow equalization chambers. The dust collection mechanism includes two suction pipes respectively connected to the upper and lower flow equalization chambers, and the suction pipes are connected to an external negative pressure device.

[0007] In addition, the cleaning device for insulation board production proposed above according to this application may also have the following additional technical features: In one embodiment of this application, the cleaning hood includes two first hoods and two second hoods. Two first cleaning units are respectively disposed on the two first hoods, and two second cleaning units are respectively disposed on the two second hoods. The two first hoods are distributed vertically, and the upper and lower ends of the two second hoods are respectively slidably installed in the two first hoods. The two first hoods and the two second hoods together form a feed inlet.

[0008] In one embodiment of this application, a flow equalization plate is provided inside the first cover, and a plurality of flow equalization holes are provided on the flow equalization plate. The flow equalization plate is located between the flow equalization cavity and the horizontal brush roller. The second cleaning unit is fixed inside the second cover. The top and bottom of the second cover are provided with sealing plates for blocking the flow equalization holes. When the second cover moves in the first cover, the volume of the suction cavity formed by the cooperation of the first cover and the second cover changes accordingly.

[0009] In one embodiment of this application, a lifting adjustment mechanism and a horizontal adjustment mechanism are further included. The lifting adjustment mechanism is used to adjust the distance between the two first covers. A telescopic section is provided in the middle of the second cover to adapt to changes in the distance between the two first covers. The horizontal adjustment mechanism is used to adjust the distance between the two second covers.

[0010] In one embodiment of this application, the suction pipe is connected to the middle of the flow equalization chamber; along the flow equalization plate from the middle to both ends, the diameter of the plurality of flow equalization holes gradually increases.

[0011] In one embodiment of this application, the first driving mechanism includes a driving box fixed to one end of a first cover, two reciprocating driving units corresponding to the two horizontal brush rollers respectively, and a rotary driving unit for driving the two horizontal brush rollers to rotate. Both the reciprocating driving units and the rotary driving unit are disposed within the driving box. The reciprocating driving unit includes two limiting cylinders fixed within the driving box and a guide plate fixed to the horizontal brush roller. The horizontal brush roller passes through the two limiting cylinders, and each limiting cylinder has a matching concave-convex surface at one opposite end. The guide plate is located between the two limiting cylinders, and rolling elements are provided at both ends of the guide plate. The rolling elements roll in cooperation with the corresponding concave-convex surfaces. When the horizontal brush roller rotates, the guide plate rotates, and the rolling elements roll along the concave-convex surfaces, causing the horizontal brush roller to reciprocate axially.

[0012] In one embodiment of this application, the rotary drive unit includes two ball spline sleeves, a drive motor fixed to a drive housing, and two gears. The two ball spline sleeves are rotatably mounted in the drive housing via bearing seats and are respectively sleeved on the spline sections at the same end of the two horizontal brush rollers. The shafts of the two gears are rotatably mounted in the drive housing via bearing seats, and the two gears mesh. The drive motor drives one of the gears to rotate. A drive pulley is fixed on the shaft of each of the two gears, and a driven pulley is fixed on each of the two ball spline sleeves. The drive pulley and the corresponding driven pulley are driven by a belt.

[0013] In one embodiment of this application, a vibration unit for vibrating an insulation board is provided in one of the first covers. The vibration unit includes a mounting frame fixed in the first cover, a vibrator elastically mounted on the mounting frame, and an abutment fixed on the vibrator. The abutment is used to contact the insulation board to transmit the vibration of the vibrator.

[0014] In one embodiment of this application, a conveying assembly for conveying insulation boards is also included. The conveying assembly includes two support conveyors with the same bearing surface height and two pressing conveyors located above the support conveyors. The pressing conveyors cooperate with the support conveyors to clamp and convey the insulation boards. A gap for installing cleaning covers is preset between the two support conveyors and between the two pressing conveyors.

[0015] Compared with the prior art, this application has at least the following beneficial effects: This application, by setting a first cleaning unit on the top and bottom surfaces of the insulation board and a second cleaning unit on each side of the insulation board, allows for simultaneous cleaning of the top, bottom, and sides of the insulation board as it passes through the cleaning hood, achieving comprehensive cleaning of multiple surfaces. The first cleaning unit employs two parallel horizontal brush rollers. While rotating and brushing, the horizontal brush rollers reciprocate axially, creating a composite motion trajectory of rotation and axial movement on the bristles. This expands the effective range of the bristles on the insulation board surface and reduces localized cleaning issues caused by a fixed rotation trajectory. To address the issue of dust accumulation and improve the uniformity of surface cleaning, the two horizontal brush rollers rotate in opposite directions, causing the swept dust and debris to tend to gather between the two horizontal brush rollers, reducing the degree to which dirt is thrown to the periphery of the clean area, and facilitating subsequent concentrated suction. By setting the horizontal and vertical brush rollers inside the cleaning hood, and setting flow equalization chambers on the upper and lower sides that are connected to the external negative pressure equipment, the dust generated by brushing can be drawn away by the negative pressure airflow in a relatively enclosed space, which helps to improve the uniformity of suction of the negative pressure airflow in the clean area and reduce dust retention and dust dispersion caused by local suction.

[0026] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0027] The following description, in conjunction with the accompanying drawings, describes a cleaning device for the production of insulation boards according to an embodiment of this application.

[0028] like Figures 1 to 8As shown in the illustration, this application provides a cleaning device for insulation board production. It can be installed on the conveying path of an insulation board production line. After the insulation board completes cutting or other processing steps that easily generate dust and debris, the insulation board directly passes through this device for surface cleaning. The cleaning device mainly includes a cleaning hood 1, two first cleaning units 2, two second cleaning units 3, and a dust extraction mechanism. The conveying component, which transports the insulation board through the cleaning device, can directly utilize existing conveying equipment. The two first cleaning units 2 correspond to the top and bottom surfaces of the insulation board, respectively, and the two second cleaning units 3 correspond to the two sides of the insulation board, respectively. This allows the insulation board to be cleaned not only by the first cleaning units 2 on its larger top and bottom surfaces when passing through the cleaning hood 1, but also by the two sides that extend continuously along the conveying direction, thus solving the problem that the sides are easily left unattended when only upper and lower brush rollers are used.

[0029] As one possible implementation, the conveying assembly for conveying the insulation board can adopt the following structure: specifically, it includes two supporting conveyors 36 with the same bearing surface height and two pressing conveyors 37 located above the supporting conveyors 36. Both the supporting conveyors 36 and the pressing conveyors 37 are belt conveyors. The pressing conveyors 37 cooperate with the supporting conveyors 36 to clamp the insulation board from above and below, forcibly clamping and conveying the insulation board to ensure the stability of the conveying and prevent the insulation board from slipping and moving during the cleaning process. The supporting conveyors 36 are mounted on a frame 39, and a lifting frame 40 is vertically mounted on the frame 39. Multiple vertical guide rods are fixed on the lifting frame 40, and guide sleeves fitted on the guide rods are fixed on the frame 39 to guide the lifting frame 40 to rise and fall. An electric push rod 41 is hinged to the frame 39, and the end of the electric push rod 41 is hinged to the lifting frame 40. The electric push rod 41 drives the lifting frame 40 to rise or fall. The pressing conveyor 37 is fixedly connected to the lifting frame 40, so the electric push rod 41 can control the distance between the pressing conveyor 37 and the supporting conveyor 36 to adapt to insulation boards of different thicknesses.

[0030] like Figure 2 As shown, gaps for installing the cleaning hood 1 are pre-set between the two supporting conveyors 36 and between the two pressing conveyors 37, thereby allowing the cleaning hood 1 to be arranged between the front and rear conveying sections. When the insulation board enters the cleaning hood 1 for brushing, its front and rear parts are still supported and constrained by the conveying components, thereby reducing the offset and tilting of the insulation board caused by the brush force and vibration, allowing the insulation board to pass through the cleaning area in a more stable posture.

[0031] like Figure 3 and Figure 4As shown, the cleaning hood 1 includes two first hood bodies 11 distributed vertically and two second hood bodies 12 located on both sides of the insulation board. Two first cleaning units 2 are respectively disposed on the two first hood bodies 11 to clean the upper and lower surfaces of the insulation board. Two second cleaning units 3 are respectively disposed on the two second hood bodies 12 to clean the sides of the insulation board. The upper and lower ends of the two second hood bodies 12 are slidably installed in the two first hood bodies 11, and the two first hood bodies 11 and the two second hood bodies 12 together form an inlet 8 for the insulation board to pass through. The above-mentioned split structure of this application enables the cleaning hood 1 to form a relatively concentrated cleaning space around the insulation board, limiting the spread of dust generated by brushing; on the other hand, the relative displacement between each hood body can provide a structural basis for adapting to insulation boards of different widths and thicknesses. In order to control the spacing between the hood bodies, this application provides a lifting adjustment mechanism and a horizontal adjustment mechanism.

[0032] Specifically, in practical applications, since the conveying assembly already includes an electric push rod 41 and a lifting frame 40 to adjust the height of the pressing conveyor 37, the upper first cover 11 can be fixedly connected to the lifting frame 40, while the lower first cover 11 can be fixedly connected to the frame 39, thereby achieving lifting control of the first cover 11. Therefore, the lifting adjustment mechanism for controlling the lifting of the first cover 11 and the lifting structure for controlling the pressing conveyor 37 can share components such as the electric push rod 41, the lifting frame 40, and the guide rod. When the insulation board thickness changes, adjusting the height of the lifting frame 40 via the electric push rod 41 allows the upper and lower horizontal brush rollers 4 to be repositioned to a suitable position for brushing the top and bottom surfaces of the insulation board.

[0033] Since the upper and lower ends of the second cover 12 respectively mate with the two first covers 11, a telescopic section 17 is provided in the middle of the second cover 12. The telescopic section 17 can be a corrugated cover similar to a corrugated pipe or a rubber elastic cover. When the distance between the two first covers 11 changes, the telescopic section 17 extends and retracts accordingly to maintain the state of covering a local area of ​​the insulation board. In this way, the second cover 12 does not need to be removed or replaced when adjusting the cleaning height of the equipment, and the continuity of the overall structure of the cleaning cover 1 can be maintained.

[0034] In the width direction, the first cover 11 is provided with a horizontal adjustment mechanism for moving the second cover 12. For example... Figure 4As shown, the horizontal adjustment mechanism can adopt a linear slide module 38. The linear slide module 38 typically includes a housing, a lead screw rotatably mounted on the housing, and a guide rod fixed on the housing. A slide is slidably mounted on the guide rod, and the lead screw is threaded into the slide. A motor fixed on the housing drives the lead screw to rotate, thereby controlling the linear movement of the slide. The housing can be fixed on the first cover 11, and the slide can be fixedly connected to the second cover 12. In this way, the linear slide module 38 can drive the second cover 12 to move along the first cover 11. Since the second cleaning unit 3 is fixed inside the second cover 12, when the second cover 12 moves, the vertical brush roller 6 moves closer to or further away from the insulation board, so that the distance between the two second cleaning units 3 can adapt to insulation boards of different widths. In summary, the lifting adjustment mechanism mainly corresponds to the change in insulation board thickness, and the horizontal adjustment mechanism mainly corresponds to the change in insulation board width. The two adjustments are independent of each other but work together on the cleaning cover 1, so that the cleaning space can better fit the actual cross-sectional dimensions of the insulation board and make full use of the negative pressure suction to clean up dust.

[0035] In this application, as Figure 4 As shown, the first cleaning unit 2 includes two parallel horizontal brush rollers 4 and a first drive mechanism 5. During the brushing and cleaning process, the two horizontal brush rollers 4 rotate in opposite directions, causing the brushing direction at the contact point between the two horizontal brush rollers 4 and the insulation board to tend towards the space between the two horizontal brush rollers 4. In this way, the dust and debris brushed off are not easily scattered in large quantities to the front and rear sides of the cleaning hood 1, but tend to gather between the two horizontal brush rollers 4, making it easier for the negative pressure airflow to carry away the dirt in a more concentrated area.

[0036] Meanwhile, the horizontal brush roller 4 does not merely rotate around its own axis; the first drive mechanism 5 also causes it to undergo a small reciprocating motion along the axial direction during rotation. The bristles of the horizontal brush roller 4 thus form a composite motion trajectory relative to the insulation board, combining rotational and axial movements, resulting in lateral changes in the position of the bristles acting on the insulation board at adjacent moments. Compared to brushing along a fixed circumferential trajectory repeatedly, this method expands the actual sweeping area of ​​the bristles, providing better disturbance and removal of dust from localized uneven areas on the insulation board surface and from dust located between fixed sweeping trajectories.

[0037] like Figure 5 and Figure 6 As shown, to simultaneously achieve the aforementioned rotational and axial reciprocating motions, the first drive mechanism 5 includes a drive housing 18 fixed to one end of the first cover 11, two reciprocating drive units respectively corresponding to the two horizontal brush rollers 4, and a rotary drive unit for driving the two horizontal brush rollers 4 to rotate. Both the reciprocating drive units and the rotary drive unit are housed within the drive housing 18. Concentrating the relevant transmission components within the drive housing 18 isolates them from the dusty brushing area within the cleaning cover 1, reducing the impact of dust on the operation of the transmission components. A dynamic sealing ring can be installed on the portion of the horizontal brush rollers 4 that passes through the drive housing 18 to prevent dust from entering the drive housing 18.

[0038] like Figure 6 As shown, each reciprocating drive unit includes two limiting cylinders 19 fixed inside the drive housing 18 and a guide disk 20 fixed on the horizontal brush roller 4. The axes of the limiting cylinders 19, the guide disk 20, and the horizontal brush roller 4 coincide. The horizontal brush roller 4 passes through the two limiting cylinders 19, and the guide disk 20 is located between the two limiting cylinders 19. The opposite ends of the two limiting cylinders 19 are provided with matching concave and convex surfaces 21, which undulate axially. Rolling elements 22 are respectively provided at both ends of the guide disk 20; the rolling elements 22 can be cylindrical rollers. The rolling elements 22 roll in cooperation with the corresponding concave and convex surfaces 21.

[0039] When the horizontal brush roller 4 rotates, the guide disk 20 rotates synchronously with the horizontal brush roller 4, causing the rolling element 22 to move along the concave-convex surface 21. Since the different circumferential positions of the concave-convex surface 21 are located at different positions along the axial direction of the horizontal brush roller 4, the guide disk 20 is continuously guided by the concave-convex surface 21 during one rotation, thus generating periodic axial displacement and driving the horizontal brush roller 4 to reciprocate along its own axial direction. Therefore, the axial reciprocating motion can be directly obtained using the original rotational motion of the horizontal brush roller 4, eliminating the need for a separate reciprocating power source for axial movement, and ensuring good synchronization between the two movements.

[0040] The rotary drive unit includes two ball spline sleeves 23, a drive motor 24, and two gears 25. The two ball spline sleeves 23 are rotatably mounted in the drive housing 18 via bearing seats 26, and are respectively fitted onto the spline sections 27 at the same end of the two horizontal brush rollers 4. The ball spline sleeves 23 are used in conjunction with the spline sections 27 because the horizontal brush rollers 4 need to receive rotational power and also need to be able to reciprocate axially: the ball spline sleeves 23 can transmit torque to the horizontal brush rollers 4, while allowing the spline sections 27 to slide axially relative to the ball spline sleeves 23, thereby avoiding the rotary drive structure from constraining the reciprocating motion of the horizontal brush rollers 4.

[0041] The shafts 28 of the two gears 25 are rotatably mounted in the drive housing 18 via bearing seats 26. The two gears 25 mesh with each other. The drive motor 24 is fixedly connected to the drive housing 18 and connected to the shaft 28 of one of the gears 25 via a coupling, thereby driving one of the gears 25 to rotate, enabling the two gears 25 to rotate in opposite directions. A drive pulley 29 is fixed to the shaft 28 of each of the two gears 25, and a driven pulley 30 is fixed to each of the two ball spline sleeves 23. The drive pulley 29 and the corresponding driven pulley 30 are driven by a belt 31. Thus, one drive motor 24 can simultaneously drive the two horizontal brush rollers 4 to rotate in opposite directions without affecting the axial reciprocating movement of each horizontal brush roller 4.

[0042] like Figure 7As shown, the second cleaning unit 3 includes a vertical brush roller 6 and a second drive mechanism 7 for driving the vertical brush roller 6 to rotate. The second cleaning unit 3 is fixed inside the corresponding second cover 12. Considering that the sides of the insulation board generally accumulate less dust, the structure of the second cleaning unit 3 is relatively simple. The second drive mechanism 7 includes a motor fixed inside the second cover 12. A transmission box is fixed to the end of the motor. The vertical brush roller 6 is rotatably mounted in the transmission box. The output shaft of the motor drives the vertical brush roller 6 to rotate through a transmission mechanism provided in the transmission box. Since the motor is located on one side of the vertical brush roller 6 in this embodiment, the transmission mechanism can be a transmission shaft connected to the output shaft of the motor. The end of the transmission shaft is reversed through a pair of bevel gears to drive the vertical brush roller 6 to rotate. Since this type of transmission mechanism is common and belongs to the known technology in the art, it is not shown in the drawings, but only described in words. When the insulation board passes through the cleaning cover 1, the two vertical brush rollers 6 contact the two sides of the insulation board respectively, and remove the dust and debris on the sides by rotating and brushing. Since the second cleaning unit 3 moves directly with the second cover 12, the horizontal adjustment mechanism can adjust the position of the vertical brush roller 6 while adjusting the width of the cleaning cover 1.

[0043] like Figure 8 As shown, one of the first housings 11 also houses a vibration unit 32 for vibrating the insulation board. The vibration unit 32 includes a mounting bracket 33 fixed inside the first housing 11, a vibrator 34 elastically mounted on the mounting bracket 33, and a contact part 35 fixed to the vibrator 34. The contact part 35 has an arc-shaped structure, and its outer circumferential surface is used to contact the insulation board and transmit the vibration generated by the vibrator 34. A rubber rod 42 is fixed on the mounting bracket 33, and the vibrator 34 is fixed to the rubber rod 42. The rubber rod 42 enables elastic mounting between the vibrator 34 and the mounting bracket 33. The vibrator 34 can be a small vibration motor.

[0044] When the insulation board passes the vibration unit 32, the contact part 35 transmits vibration to the insulation board, causing it to vibrate. This disturbs and loosens some of the dust adhering to the surface or local depressions of the insulation board, which is then further brushed away by the adjacent horizontal brush roller 4. The vibration unit 32 and the horizontal brush roller 4 are not two independent cleaning mechanisms, but rather use vibration to assist in loosening the dust, followed by brushing to complete the peeling, and finally the dust is carried away by the negative pressure airflow. The vibrator 34 is elastically installed, which also reduces the direct transmission of vibration to the first cover 11 and the frame 39.

[0045] like Figure 4 and Figure 8As shown, a flow equalization plate 13 is provided inside the first cover 11, forming a flow equalization cavity 9 between the flow equalization plate 13 and the first cover 11. The flow equalization plate 13 is located between the flow equalization cavity 9 and the horizontal brush roller 4, and has multiple flow equalization holes 14. The side of the flow equalization plate 13 away from the horizontal brush roller 4 forms a flow equalization cavity 9 with the first cover 11, and the side of the flow equalization plate 13 facing the horizontal brush roller 4, together with the first cover 11 and the second cover 12, forms a dust suction cavity 16. The dust suction mechanism includes two suction pipes 10 that are respectively connected to the flow equalization cavities 9 in the upper and lower first covers 11. The suction pipes 10 are connected to an external negative pressure device. When the negative pressure device is working, the air containing dust in the cleaning cover 1 enters the flow equalization cavity 9 through the flow equalization holes 14, and is then discharged through the suction pipes 10, so that the dust raised by the horizontal brush roller 4 and the vertical brush roller 6 can be promptly extracted inside the relatively closed cleaning cover 1. The multiple flow equalization holes 14 on the flow equalization plate 13 can also be configured with differentiated apertures, with the apertures of the flow equalization holes 14 gradually decreasing in size from both ends of the flow equalization plate 13 towards the middle. Because the flow paths between different positions and the suction pipe 10 differ after the negative pressure airflow enters the flow equalization chamber 9, it can easily cause strong suction in some areas and weak suction in others. By changing the aperture of the flow equalization holes 14, the air intake volume can be adjusted using the flow resistance generated by different sized orifices, thereby reducing the suction differences between different positions on the flow equalization plate 13 and creating a relatively balanced negative pressure airflow over a longer cleaning area.

[0046] Furthermore, considering that the second cover 12 can move along the first cover 11, causing the lateral dimension of the suction chamber 16 formed by the cooperation of the first cover 11 and the second cover 12 to change accordingly, in order to adapt the actual suction area to the cleaning area, sealing plates 15 for blocking the flow equalization holes 14 are provided at both the top and bottom of the second cover 12. Figure 4 and Figure 7 As can be seen, when the second cover 12 moves along the first cover 11 to adapt to insulation boards of different widths, the sealing plate 15 moves synchronously, changing the number of blocked flow equalization holes 14. Simultaneously, the volume of the suction chamber 16 formed by the cooperation of the first cover 11 and the second cover 12 also changes accordingly. This allows the movement of the second cover 12 to not only change the position of the vertical brush roller 6 but also synchronously change the area actually involved in suction. For example, when cleaning a narrower insulation board and causing the second cover 12 to move towards the center, some of the flow equalization holes 14 located outside the cleaning area can be blocked by the sealing plate 15, reducing the negative pressure airflow from ineffective areas and allowing the limited negative pressure flow to act more effectively near the insulation board. Compared to simply expanding the cleaning cover 1 and continuously suctioning the entire space, this structure helps maintain a better correspondence between the suction range and the current cleaning range.

[0047] In actual use, the equipment is first adjusted according to the size of the insulation board to be cleaned. The distance between the two upper and lower first covers 11 is changed by the lifting adjustment mechanism, so that the upper and lower horizontal brush rollers 4 correspond to the top and bottom surfaces of the insulation board, respectively. The positions of the two second covers 12 are changed by the horizontal adjustment mechanism, so that the two vertical brush rollers 6 correspond to the two sides of the insulation board, respectively. While the second covers 12 move, the sealing plate 15 simultaneously adjusts the effective opening range of the flow equalization holes 14, so that the negative pressure suction area adapts to the adjusted cleaning area.

[0048] Subsequently, the conveying assembly, first drive mechanism 5, second drive mechanism 7, and negative pressure equipment are activated. The insulation board is held by the supporting conveyor 36 and the pressing conveyor 37 and enters the cleaning hood 1. The upper and lower first cleaning units 2 clean the top and bottom surfaces of the insulation board respectively. The horizontal brush roller 4 rotates in opposite directions while reciprocating along the axial direction, causing dirt to accumulate between the two horizontal brush rollers 4. The two side second cleaning units 3 simultaneously clean the two sides of the insulation board, and the vibration unit 32 assists in loosening some of the attached dust. The dust-laden airflow generated during the cleaning process enters the upper and lower equalization chambers 9 through the equalization hole 14 and is then discharged through the dust suction pipe 10, thus removing the raised dust from the cleaning area while brushing away the dirt. After cleaning, the insulation board continues to be conveyed to the subsequent process by the conveying assembly.

[0049] In summary, this application, through the cooperation of two first cleaning units 2 and two second cleaning units 3, can simultaneously clean the top, bottom, and two sides of the insulation board during continuous conveying. By having the horizontal brush roller 4 rotate and reciprocate axially, the effective range of the brush bristles on the surface of the insulation board is expanded. Furthermore, the counter-rotation of the two horizontal brush rollers 4 concentrates the brushed-off dirt, facilitating subsequent suction. The adjustable first cover 11 and second cover 12 adapt to insulation boards of different widths and thicknesses. The linkage between the second cover 12, the sealing plate 15, the flow equalization hole 14, and the dust suction chamber 16 allows the negative pressure suction area to be adjusted according to the cleaning range.
