Description

Technical Field

[0001] This utility model relates to the field of rock wool production and processing equipment, specifically to a rock wool surface cleaning device. Background Technology

[0002] In the production of rock wool boards, ensuring surface cleanliness is crucial for product quality and subsequent processing. While existing rock wool surface cleaning devices each have their own characteristics, they generally suffer from significant limitations. Some devices can only clean the top and bottom surfaces of the rock wool board. For example, the device involved in patent CN208098689U uses brush rollers with bristles to clean the top and bottom surfaces of the rock wool board and collects dust using a dust collection hood. A lifting mechanism is used to adjust the positions of the upper and lower brush rollers to accommodate rock wool boards of different thicknesses. However, this type of device completely neglects the cleaning needs of the four sides of the rock wool board. In practical applications, residual dust and impurities on the sides may affect the adhesion between the rock wool board and other materials, reducing overall performance.

[0003] Some cleaning equipment has complex structures, making it difficult to operate and maintain. For example, some equipment using complex mechanical transmission and control systems not only increases production costs but also frequently malfunctions, severely impacting production efficiency. Furthermore, traditional equipment often struggles to flexibly adapt to the cleaning requirements of rock wool boards of different sizes. When dealing with products of varying dimensions, it frequently requires manual adjustments to equipment parameters or replacement of parts, which is both time-consuming and labor-intensive, failing to meet the demands of modern, high-efficiency production. In addition, some equipment lacks effective collection and treatment mechanisms for the dust and debris generated during the cleaning process, leading to environmental pollution, harming worker health, and contradicting the principles of environmentally friendly production. Utility Model Content

[0004] The purpose of this utility model is to provide a rock wool surface cleaning device that is thorough, has a reasonable structure, is versatile, and does not pollute the environment.

[0005] This utility model is achieved through the following technical solution: a rock wool surface cleaning device, including a frame, a roller conveyor, an automatic rotating device, a second cleaning component, a third cleaning component, a second dust suction head, a third dust suction head, a telescopic frame assembly, and two correction devices;

[0006] The roller conveyor is mounted on the upper part of the frame; the automatic rotating device is located in the middle of the roller conveyor, and the automatic rotating device includes two conical rollers symmetrically arranged vertically. The lower conical roller is rotatably mounted on the frame, and a mounting frame is provided on the frame. A lifting frame is slidably mounted on the mounting frame, and a first electric push rod for driving the lifting frame to rise and fall is mounted on the mounting frame. The upper conical roller is rotatably mounted on the lifting frame. A first motor for driving the corresponding side conical roller to rotate is mounted on both the frame and the lifting frame; two correction devices are arranged side by side above the frame, and each correction device includes two sets of symmetrically arranged limiting components. The limiting components include a stop bar and a first electric push rod. Two electric push rods are used. The stop rods are located above the roller conveyor. The section of the stop rod near the starting end of the roller conveyor bends outward. The second electric push rod is mounted on the frame and its output shaft is connected to the stop rod. Each of the four stop rods is equipped with a first dust suction head and a first cleaning component. Both ends of the telescopic frame assembly are connected to two stop rods of a correction device near the starting end of the roller conveyor. The second cleaning component and the second dust suction head are both mounted on the telescopic frame assembly. Two mounting seats are arranged side by side below the telescopic frame assembly. The two mounting seats are connected to the bottom ends of the two stop rods respectively. The third cleaning component and the third dust suction head are mounted on the mounting seats.

[0007] The working principle of this technical solution is as follows: the roller conveyor transports rock wool boards as a carrier; the baffles of the two correction devices adjust the spacing through the second electric push rod to guide and limit the rock wool boards, ensuring that they move along the preset path; the upper and lower conical rollers of the automatic rotating device are driven to rotate by the first motor, and the difference in linear velocity at both ends of the conical rollers drives the rock wool boards to rotate horizontally (close to 90°), so that the originally uncleaned sides turn towards the cleaning components; the first cleaning component is responsible for cleaning the sides, the second cleaning component is responsible for cleaning the upper surface, and the third cleaning component is responsible for cleaning the lower surface, which work in sync with the first, second, and third suction heads to remove dust, achieving cleaning without dead angles.

[0008] To better demonstrate the present invention, the telescopic frame assembly further includes a sleeve and two L-shaped movable plates. The sleeve is connected to the lifting frame, and the ends of the two L-shaped movable plates are slidably installed inside the sleeve. Two U-shaped guide rails are symmetrically arranged on the two stops of a correction device adjacent to the starting end of the roller conveyor. The lower parts of the two L-shaped movable plates are slidably installed between the two U-shaped guide rails of the corresponding side stops.

[0009] To better demonstrate the present invention, the second cleaning component further includes two second roller brushes and two third motors. The two second roller brushes are rotatably mounted on the inner walls of two L-shaped moving plates facing each other, and the two third motors are mounted on the two L-shaped moving plates. The output shafts of the two third motors are respectively connected to the rotating shafts of the two second roller brushes.

[0010] To better demonstrate the utility model, the second suction head is further provided in two parts and is respectively mounted on the L-shaped movable plates on both sides, and is located next to the second roller brush.

[0011] To better demonstrate the present invention, the third cleaning component further includes two third roller brushes and two fourth motors. The two third roller brushes are rotatably mounted on the upper surfaces of two mounting bases, and the two fourth motors are mounted on the two mounting bases. The output shafts of the two fourth motors are respectively connected to the rotating shafts of the two third roller brushes.

[0012] To better test this utility model, the third suction head is further provided in two parts, which are respectively mounted on the mounting bases on both sides and located next to the third roller brush.

[0013] To better test this utility model, the first cleaning component further includes a first roller brush and a second motor. A bracket is provided on the stop bar. The first roller brush is rotatably mounted on the bracket facing the conveying path of the roller conveyor. The second motor is mounted on the bracket and its output shaft is connected to the rotating shaft of the first roller brush.

[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0015] (1) This utility model achieves comprehensive cleaning of the upper and lower surfaces and all sides of the rock wool board through the coordinated design of an automatic rotating device, multiple cleaning components and vacuum heads. The two conical rollers of the automatic rotating device can drive the rock wool board to rotate, so that the originally difficult-to-clean sides can be fully exposed. With the first cleaning component and the first vacuum head on the four baffles, as well as the second and third cleaning components and the second and third vacuum heads, dust and impurities on all surfaces of the rock wool board can be thoroughly removed, solving the problem of cleaning dead corners in the prior art, greatly improving the cleaning quality of the rock wool board, and providing a better foundation for subsequent processing steps;

[0016] (2) This utility model, by setting a telescopic frame assembly, can be adjusted according to the width of the rock wool board, and can adapt to the cleaning of rock wool boards of different sizes by sliding connection with the U-shaped guide rail and the stop bar. The stop bar of the correction device is bent outward at one end, which can guide the rock wool board at the starting end of the roller conveyor. The second electric push rod can drive the stop bar to move and correct the position of the rock wool board, ensuring that the rock wool board is always in the right position during the cleaning process, effectively avoiding the problem of incomplete cleaning caused by the position deviation of the rock wool board, and improving the adaptability and versatility of the equipment to rock wool boards of different specifications;

[0017] (3) In the process of conveying rock wool boards, the conical roller of the automatic rotating device is driven to rotate by the first motor, which drives the rock wool board to rotate synchronously; at the same time, the roller brushes of the first, second and third cleaning components are driven by the corresponding motors to clean the surface of the rock wool board; the first, second and third dust suction heads promptly remove the dust that has been swept up. The whole process is highly automated, requiring little manual intervention, which greatly shortens the cleaning time, improves production efficiency, and reduces labor costs, which is in line with the development trend of efficient production in modern industry.

[0018] (4) This utility model provides a complete dust collection system that can effectively collect dust generated during the cleaning process. The first, second and third dust collection heads correspond to the cleaning areas of different surfaces of the rock wool board, and the dust swept up is sucked away in time to avoid dust flying in the production environment, reduce pollution to the workshop air, protect the health of workers, and also meet the requirements of environmentally friendly production, which helps enterprises achieve green production.

[0028] Example 1:

[0029] The main structure of this embodiment is as follows: Figures 1-4 As shown, it includes a frame 1, a roller conveyor 2, an automatic rotating device, a second cleaning component, a third cleaning component, a second vacuum head 20, a third vacuum head 21, a telescopic frame assembly, and two correction devices.

[0030] The roller conveyor 2 is installed on the upper end of the frame 1; the automatic rotating device is located in the middle of the roller conveyor 2, and the automatic rotating device includes two tapered rollers 4 symmetrically arranged vertically. The lower tapered roller 4 is rotatably mounted on the frame 1. The frame 1 is provided with a mounting frame 3, and a lifting frame 6 is slidably mounted on the mounting frame 3. A first electric push rod 7 for driving the lifting frame 6 to rise and fall is installed on the mounting frame 3. The upper tapered roller 4 is rotatably mounted on the lifting frame 6. Both the frame 1 and the lifting frame 6 are equipped with a first motor 5 for driving the corresponding tapered roller 4 to rotate; two correction devices are arranged side by side above the frame 1. Each correction device includes two sets of symmetrically arranged limiting components. The limiting components include a stop rod 8 and a second electric... Push rod 10, the stop rod 8 is located above the roller conveyor 2, the stop rod 8 is bent outward at a section near the starting end of the roller conveyor 2, the second electric push rod 10 is mounted on the frame 1 and its output shaft is connected to the stop rod 8; each of the four stop rods 8 is equipped with a first dust suction head 19 and a first cleaning component; both ends of the telescopic frame assembly are respectively connected to two stop rods 8 of a correction device near the starting end of the roller conveyor 2, the second cleaning component and the second dust suction head 20 are both mounted on the telescopic frame assembly; two mounting seats 18 are arranged side by side below the telescopic frame assembly, the two mounting seats 18 are respectively connected to the bottom ends of the two stop rods 8, and the third cleaning component and the third dust suction head 21 are mounted on the mounting seats 18.

[0031] The specific implementation process is as follows: Rock wool boards are placed at the starting end of roller conveyor 2. After starting the equipment, roller conveyor 2 drives the rock wool boards to move towards the center. In the correction device adjacent to the starting end of the conveyor, the second electric push rod 10 drives two stop rods 8 to adjust the spacing. The bending section first guides the rock wool board, and the main body section limits the movement, ensuring the rock wool board is conveyed in the center. The first cleaning component on the stop rod 8, the first roller brush 12, is driven by the second motor 13 to rotate and contact both sides of the rock wool board, cleaning the side dust. The first dust suction head 19 simultaneously sucks up the dust. The second cleaning component on the telescopic frame assembly cleans the upper surface of the rock wool board, and the second dust suction head 20 sucks up the dust from the upper surface. The third cleaning component on the mounting base 18 cleans the lower surface of the rock wool board, and the third dust suction head 21 sucks up the dust from the lower surface. The rock wool board moves to the automatic rotating device in the middle of the roller conveyor 2. The first electric push rod 7 drives the lifting frame 6 to descend, clamping the rock wool board between the upper and lower conical rollers 4. The first motors 5 on both sides drive the conical rollers 4 to rotate, using the difference in linear speed of the conical rollers to rotate the rock wool board horizontally by 90°, so that the other two uncleaned sides turn towards the subsequent cleaning area. The rotated rock wool board continues to be conveyed to the other side correction device. The stop rod 8 of this device adjusts the spacing and limits the position via the second electric push rod 10. The first cleaning component and the first dust suction head 19 on the stop rod 8 clean and vacuum the two newly turned sides. The rock wool board with full surface cleaning is output from the end of the roller conveyor 2, completing the cleaning process.

[0032] Example 2:

[0033] This embodiment further defines the structure of the telescopic frame assembly based on the above embodiments, such as... Figure 3 , Figure 4 As shown, the telescopic frame assembly includes a sleeve 111 and two L-shaped movable plates 112. The sleeve 111 is connected to the lifting frame 6. The ends of the two L-shaped movable plates 112 are slidably mounted on the inner side of the sleeve 111. Two U-shaped guide rails 113 are symmetrically arranged on the two baffles 8 of a correction device adjacent to the starting end of the roller conveyor 2. The lower parts of the two L-shaped movable plates 112 are slidably mounted between the two U-shaped guide rails 113 of the corresponding side baffles 8. The L-shaped movable plates 112 can slide horizontally along the inner side of the sleeve 111, while their lower parts slide along the U-shaped guide rails 113 on the baffles 8, ensuring that the second cleaning component and the second vacuum head 20 are always aligned with the upper surface of the rock wool board, avoiding cleaning omissions due to changes in the width of the rock wool board.

[0034] The specific implementation process is as follows: when the width of the rock wool board changes, in the correction device near the starting end of the conveying process, the second electric push rod 10 drives the two stop rods 8 to move synchronously in opposite directions, increasing or decreasing the distance between them. When the stop rods 8 move, the U-shaped guide rail 113 on their surface drives the L-shaped moving plate 112 to slide along the inner side of the sleeve 111, so that the distance between the two L-shaped moving plates 112 matches the width of the rock wool board. During the sliding process of the L-shaped moving plate 112, the second cleaning component and the second vacuum head 20 installed on it are always facing the upper surface of the rock wool board, ensuring that the cleaning range covers the entire upper surface. At the same time, the sleeve 111 is connected to the lifting frame 6 and moves up and down synchronously with the lifting frame 6 to adapt to the upper surface height of rock wool boards of different thicknesses. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0035] Example 3:

[0036] This embodiment further defines the structure of the second cleaning component based on the above embodiments, such as... Figure 3 , Figure 4 As shown, the second cleaning assembly includes two second roller brushes 14 and two third motors 15. The two second roller brushes 14 are rotatably mounted on the opposing inner walls of two L-shaped moving plates 112, and the two third motors 15 are respectively mounted on the two L-shaped moving plates 112. The output shafts of the two third motors 15 are respectively connected to the rotating shafts of the two second roller brushes 14. The two second roller brushes 14 are mounted on the opposing inner walls of the L-shaped moving plates 112, and their spacing is adjusted synchronously with the L-shaped moving plates 112 to ensure that the roller brushes are in close contact with the upper surface of the rock wool board, and the dust attached to the upper surface is cleaned by rotational friction.

[0037] The specific implementation process is as follows: When the equipment starts, the two third motors 15 start synchronously, and the output shaft drives the second roller brush 14 to rotate perpendicular to the conveying direction. The brush bristles on the roller brush surface contact the upper surface of the rock wool board. When the rock wool board passes under the telescopic frame assembly with the roller conveyor 2, the rotating second roller brush 14 sweeps its entire upper surface, removing dust from the surface. Since the spacing of the L-shaped moving plates 112 has been adjusted according to the width of the rock wool board, the two second roller brushes 14 cover the two sides of the upper surface respectively, ensuring no cleaning dead corners. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0038] Example 4:

[0039] This embodiment, based on the above embodiment, further defines the number and position of the second suction head 20, such as... Figure 3 As shown, there are two second suction heads 20, which are respectively installed on the L-shaped movable plates 112 on both sides and located beside the second roller brush 14. The second suction heads 20 are located beside the second roller brush 14 and utilize the principle of negative pressure to suck up the dust in time when the second roller brush 14 is cleaning the dust, so as to prevent the dust from adhering to the surface of the rock wool board again or drifting into the air, thereby improving the dust removal efficiency of the upper surface.

[0040] The specific implementation process is as follows: the second suction head 20 and the second roller brush 14 are simultaneously activated and connected to the same vacuum cleaner system, with their suction inlets directly facing the contact area between the second roller brush 14 and the rock wool board. After the second roller brush 14 sweeps away the dust from the upper surface, the second suction head 20 immediately sucks in the dust through negative pressure, ensuring that the dust is collected before it falls back down. When adjusted with the L-shaped moving plate 112, the second suction head 20 always maintains a fixed distance from the second roller brush 14, ensuring that the suction range and the cleaning range are perfectly matched. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0041] Example 5:

[0042] This embodiment further defines the structure of the third cleaning component based on the above embodiments, such as... Figure 4 As shown, the third cleaning component includes two third roller brushes 16 and two fourth motors 17. The two third roller brushes 16 are rotatably mounted on the upper surfaces of two mounting bases 18, and the two fourth motors 17 are mounted on the two mounting bases 18. The output shafts of the two fourth motors 17 are respectively connected to the rotating shafts of the two third roller brushes 16. The third roller brushes 16 are mounted on the upper surface of the mounting base 18, and their height is slightly higher than the upper edge of the roller of the roller conveyor 2 to ensure contact with the lower surface of the rock wool board. The mounting base 18 moves synchronously with the stop bar 8 to adapt to the cleaning of the lower surface of rock wool boards of different widths.

[0043] The specific implementation process is as follows: the mounting base 18 is connected to the stop bar 8. When the stop bar 8 adjusts its spacing according to the width of the rock wool board, the mounting base 18 simultaneously drives the third roller brush 16 to adjust its position, so that the two third roller brushes 16 correspond to the two sides of the lower surface of the rock wool board respectively. The fourth motor 17 drives the third roller brush 16 to rotate in a direction perpendicular to the conveying direction. When the rock wool board moves with the roller conveyor 2, the lower surface contacts the third roller brush 16, and the roller brush cleans the dust on the lower surface through the friction of the bristles. Since the third roller brush 16 is installed at the gap between the rollers of the roller conveyor 2, interference with the rollers is avoided, ensuring continuous cleaning. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0044] Example 6:

[0045] This embodiment, based on the above embodiment, further defines the positional relationship of the third suction head 21, such as... Figure 4 As shown, there are two third dust suction heads 21, which are respectively installed on the mounting bases 18 on both sides and located beside the third roller brush 16. The third dust suction head 21 is located beside the third roller brush 16 and moves synchronously with the third roller brush 16. While the third roller brush 16 is cleaning the dust on the lower surface, it promptly sucks away the dust through negative pressure, preventing the dust from accumulating on the surface of the roller conveyor 2 or adhering to the lower surface of the rock wool board again.

[0046] The specific implementation process is as follows: the third suction head 21 and the third roller brush 16 are activated synchronously, with its suction inlet close to the contact area between the third roller brush 16 and the lower surface of the rock wool board. When the third roller brush 16 sweeps the dust on the lower surface, the third suction head 21 immediately sucks the detached dust into the collection system. When the mounting base 18 is adjusted with the stop lever 8, the relative position of the third suction head 21 and the third roller brush 16 remains unchanged, ensuring that the suction range always covers the cleaning range of the third roller brush 16, adapting to the dust removal needs of the lower surface of rock wool boards of different widths. Other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0047] Example 7:

[0048] This embodiment further defines the structure of the first cleaning component based on the above embodiments, such as... Figure 3 As shown, the first cleaning assembly includes a first roller brush 12 and a second motor 13. A bracket is mounted on the stop bar 8, and the first roller brush 12 is rotatably mounted on the bracket facing the conveying path of the roller conveyor 2. The second motor 13 is mounted on the bracket, and its output shaft is connected to the rotating shaft of the first roller brush 12. The first cleaning assembly cleans the side of the rock wool board by having the second motor 13 drive the first roller brush 12 to rotate. The first roller brush 12 is mounted on the bracket of the stop bar 8, and the bracket faces the conveying path of the roller conveyor 2, ensuring close contact between the roller brush and the side of the rock wool board. The rotation direction of the roller brush is perpendicular to the conveying direction, and the friction of the bristles removes dust from the side.

[0049] The specific implementation process is as follows: the bracket on the baffle 8 faces the conveying path, so that the bristles of the first roller brush 12 naturally contact the side of the rock wool board; when the second electric push rod 10 adjusts the distance between the baffle 8, the first roller brush 12 moves synchronously with the baffle 8, always maintaining contact with the side, and the contact pressure can be finely adjusted by the distance between the baffle 8. The second motor 13 drives the first roller brush 12 to rotate. When the rock wool board moves with the roller conveyor 2, the side continuously contacts the rotating first roller brush 12, and the bristles sweep away the dust on the side; the dust generated during sweeping is promptly sucked away by the first suction head 19 on the side, completing the side cleaning. The other parts of this embodiment are the same as those in the above embodiment, and will not be described again.

[0050] It is understood that the working principle and process of the rock wool surface cleaning device structure according to one embodiment of the present utility model, such as the motor, the dust suction head, the PLC controller 9, etc., are existing technologies and are well known to those skilled in the art, and will not be described in detail here.

[0051] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
