Description

Technical Field

[0001] This utility model belongs to the field of coating and spraying technology, and specifically relates to a device for spraying a wave-absorbing coating on the surface of EPS foam board. Background Technology

[0002] EPS (expanded polystyrene) foam board is widely used in many fields due to its lightweight, heat insulation, sound insulation, and excellent cushioning properties. In the construction industry, it is a commonly used exterior wall insulation material, which can effectively reduce the energy consumption of buildings and improve indoor thermal comfort. Since building exterior walls are exposed to the natural environment for a long time, they are affected by various factors such as wind, sun, rain, ultraviolet radiation, and temperature changes. Therefore, a coating is needed to provide an extra layer of protection for the EPS foam board.

[0003] However, when using common spraying equipment, the nozzle is always in a vertical position for spraying. When encountering foam boards with inclined surfaces, the vertical nozzle will cause the paint to be sprayed at a large incident angle onto the inclined surface, which can easily lead to uneven coating thickness and reduce the overall quality of the foam board.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an EPS foam board surface microwave absorbing coating spraying device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a spraying device for an absorbent coating on the surface of EPS foam board, comprising a frame, a conveyor belt inside the frame, a cleaning component on the upper side of the conveyor belt, a mounting frame on the upper side of the conveyor belt, a spraying component on the top of the mounting frame, an angle adjustment component at the bottom of the mounting frame, an elastic support component at the adjustment end of the angle adjustment component, and the spraying end of the spraying component being fixedly installed inside the elastic support component.

[0008] Furthermore, the cleaning assembly includes two storage frames, which are respectively fixedly installed on both sides of the frame. Telescopic plates are movably connected inside the two storage frames, and a cleaning brush is fixedly installed on the top of the telescopic plates. Limiting bolts are threadedly connected to the outer surfaces of the two storage frames, and one end of each limiting bolt extends into the interior of the storage frame and contacts the corresponding outer surface of the telescopic plate.

[0009] Furthermore, the spraying assembly includes a spraying pump, which is fixedly mounted on a mounting bracket. An input pipe is fixedly connected to the input end of the spraying pump, and a paint tank is fixedly connected to one end of the input pipe. An output pipe is fixedly connected to the output end of the spraying pump, and a spray layer is fixedly connected to one end of the output pipe. Several spray nozzles are fixedly installed at the bottom of the spray layer.

[0010] Furthermore, the angle adjustment assembly includes a connecting shaft, which is movably mounted to a mounting bracket. A handle is fixedly connected to one end of the connecting shaft, and a connecting plate is fixedly connected to the other end. A limit rod is fixedly connected to one side of the connecting plate. Several limit holes are provided at the bottom of the mounting bracket, and the limit rod engages with the limit holes. A fixing plate is fixedly connected to the other side of the connecting plate, and the output tube passes through the fixing plate. A slider is fixedly connected to one end of the fixing plate. A sliding groove is provided on one side of the interior of the mounting bracket, and the slider is movably connected to the interior of the sliding groove.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model adjusts the angle to be perpendicular to the inclined surface of the foam board by means of an angle adjustment component.

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0030] Please see Figures 1-7 As shown, this utility model is a spraying device for an EPS foam board surface microwave absorbing coating, including a frame 1, a conveyor belt 2 inside the frame 1, a cleaning component 3 on the upper side of the conveyor belt 2, a mounting frame 4 on the upper side of the conveyor belt 2, a spraying component 5 on the top of the mounting frame 4, an angle adjustment component 6 at the bottom of the mounting frame 4, an elastic support component 7 at the adjustment end of the angle adjustment component 6, and the spraying end of the spraying component 5 is fixedly installed inside the elastic support component 7.

[0031] During operation, the angle adjustment component 6 is first rotated according to the inclined surface of the foam board. The angle adjustment component 6 drives the elastic support component 7 to adjust its angle. The elastic support component 7 drives the spraying end of the spraying component 5 to adjust to a perpendicular angle with the inclined surface. Then, the foam board is placed above the conveyor belt 2, and the conveyor belt 2 drives the foam board to be transported to the bottom of the cleaning component 3, so that the cleaning component 3 cleans the surface of the foam board. After cleaning, the foam board comes into contact with the elastic support component 7. At the same time, the spraying component 5 is started to spray the foam board. During the movement, the foam board pushes the elastic support component 7 to move upward, so that the output end of the spraying component 5 always maintains the same height as the foam board.

[0032] This invention uses the angle adjustment component 6 to adjust to a perpendicular angle with the inclined surface of the foam board. When the inclined surface of the foam board is perpendicular, the paint can be sprayed onto the inclined surface in a vertical direction, avoiding the problem of excessive incident angle caused by the inclined surface, preventing paint from accumulating on the inclined surface, and improving the spraying quality.

[0033] In one embodiment, the cleaning component 3 includes two storage frames 301, which are fixedly installed on both sides of the frame 1. Telescopic plates 302 are movably connected inside the two storage frames 301. A cleaning brush 303 is provided on the upper side of the telescopic plate 302. The top ends of the two telescopic plates 302 are fixedly installed together with the cleaning brush 303. Limiting bolts 304 are threadedly connected to the outer surfaces of the two storage frames 301. One end of each limiting bolt 304 extends into the interior of the storage frame 301 and contacts the corresponding outer surface of the telescopic plate 302.

[0034] By rotating the limiting bolt 304, one end of the limiting bolt 304 is no longer pressing against the corresponding telescopic plate 302. At this time, the telescopic plate 302 inside the storage frame 301 can be moved, thereby causing the telescopic plate 302 to move the cleaning brush 303 to a suitable position. After the cleaning brush 303 has moved to the suitable position, the limiting bolt 304 is rotated again, so that the telescopic plate 302 will not move inside the storage frame 301 under the pressure of the limiting bolt 304. By adjusting the position of the cleaning brush 303, which is made of soft material, it can clean foam boards of different thicknesses.

[0035] In one embodiment, the spraying assembly 5 includes a spraying pump 501, which is fixedly mounted on a mounting bracket 4. An input pipe 502 is fixedly connected to the input end of the spraying pump 501, and a paint tank 503 is fixedly connected to one end of the input pipe 502. An output pipe 504 is fixedly connected to the output end of the spraying pump 501, and a spray layer 505 is fixedly connected to one end of the output pipe 504. A plurality of spray nozzles 506 are fixedly mounted at the bottom of the spray layer 505.

[0036] The spray pump 501 is started to transport the paint in the paint tank 503 to the input pipe 502, and then through the input pipe to the output pipe 504, and then through the output pipe 504 to the spray layer 505, and then sprayed out through the nozzle 506.

[0037] In one embodiment, the angle adjustment component 6 includes a connecting shaft 601, which is movably mounted to a mounting bracket 4. One end of the connecting shaft 601 is fixedly connected to a handle 602, and the other end is fixedly connected to a connecting plate 603. A limiting rod 604 is fixedly connected to one side of the connecting plate 603. The mounting bracket 4 has several limiting holes 401 at its bottom, and the limiting rod 604 engages with the limiting holes 401. A fixing plate 605 is fixedly connected to the other side of the connecting plate 603, and the output pipe 504 passes through the fixing plate 605. A slider 606 is fixedly connected to one end of the fixing plate 605. A sliding groove 402 is provided inside one side of the mounting bracket 4, and the slider 606 is movably connected to the inside of the sliding groove 402. A first spring 403 is provided between the slider 606 and the sliding groove 402.

[0038] By pressing the handle 602, the connecting shaft 601 moves to the left. The connecting shaft 601 then moves the connecting plate 603 to the left. The connecting plate 603 moves the limiting rod 604 to the left within the limiting hole 401. Simultaneously, the connecting plate 603 moves the fixing plate 605 to the left. The fixing plate 605 then moves the slider 606 to the left within the sliding groove 402. During this movement, the slider 606 compresses the first spring 403. One end of the first spring 403 is fixedly connected to the sliding groove 402, and the other end is movably connected to the slider 606. At this point, the limiting rod 604 moves out of the limiting hole 401, releasing its limitation on the connecting shaft 601. By rotating the handle 602, the connecting shaft 601 is rotated, which in turn rotates the limiting rod 604. Simultaneously, the connecting plate 603 rotates the fixing plate 605, thus adjusting the angle of the fixing plate 605. After the angle adjustment is complete, by releasing the handle 602, the first spring 403 pushes the slider 606 to move to the right within the sliding groove 402. The slider 606 then moves the fixing plate 605 to the right, which in turn moves the connecting plate 603 to the right. The connecting plate 603 then moves the limiting rod 604 to the right until it reaches the corresponding limiting hole 401, thereby limiting and fixing the connecting shaft 601.

[0039] In one embodiment, the elastic support component 7 includes a support frame 701, the spray layer 505 is fixedly installed on the top of the inner wall of the support frame 701, two telescopic rods 702 are fixedly connected to the top of the support frame 701, two telescopic cylinders 703 are fixedly installed at the bottom of the fixing plate 605, the two telescopic rods 702 are movably connected to the interior of the corresponding telescopic cylinders 703, and a second spring 704 is fixedly installed between the telescopic rods 702 and the interior of the telescopic cylinders 703.

[0040] During the aforementioned process, when the fixed plate 605 rotates, it drives the telescopic cylinder 703 to rotate, which in turn drives the telescopic rod 702 to rotate. The telescopic rod 702 then drives the support frame 701 to rotate, which in turn drives the spray head 506 to rotate, thus adjusting the angle of the spray layer 505 and the spray head 506. The bottom of the support frame 701 is equipped with several guide wheels. During operation, when the inclined surface of the foam board contacts the bottom of the support frame 701, the guide wheels contact the inclined surface of the foam board, causing the foam board to push the support frame 701 upwards. The support frame 701 then drives the two telescopic rods 702 to slide upwards within their corresponding telescopic cylinders 703. During this sliding process, the telescopic rods 702 compress the second spring 704. Simultaneously, the support frame 701 drives the spray layer 505 and the spray head 506 upwards, ensuring that the height of the spray head 506 relative to the inclined surface of the foam board remains consistent. After spraying is completed, the foam board... Separating from the support frame 701, the support frame 701 is no longer lifted. At this time, the second spring 704 pushes the telescopic rod 702 to move downward within the telescopic cylinder 703. The telescopic rod 702 drives the support frame 701 to move downward, thereby moving and resetting the spray layer 505 and the nozzle 506 downward, so that the next foam board can be sprayed. During the movement of the foam board, it pushes the elastic support component 7 to move upward, so that the output end of the spray component 5 always maintains the same height as the foam board. This can prevent uneven thickness caused by the distance between the nozzle and the foam board being too close or too far, and make the coating thickness consistent across the entire foam board surface.

[0041] In one embodiment, for the frame 1, two support plates 101 are fixedly installed on both sides of the frame 1, and electric push rods 102 are fixedly installed on the top of the two support plates 101. The mounting bracket 4 is fixedly installed on the output end of the electric push rods 102.

[0042] The height of the mounting bracket 4 can be adjusted by activating the electric push rod 102, which facilitates the height adjustment of the spray head and ensures that the spray head is at the appropriate height with foam boards of different thicknesses before spraying.

[0043] In one embodiment, for the conveyor belt 2, a plurality of push plates 201 are fixedly installed on the outer surface of the conveyor belt 2.

[0044] When the conveyor belt 3 moves, it drives the pusher plate 201 to move. The pusher plate 201 can push the foam board to prevent the foam board from getting stuck under the support frame 701, thus maintaining the stability and continuity of the production process.

[0045] In summary, with the help of the above-mentioned technical solution of this utility model, 1. by adjusting the angle adjustment component 6 to a perpendicular angle to the inclined surface of the foam board, when the inclined surface of the foam board is perpendicular, the paint can be sprayed onto the inclined surface in a vertical direction, avoiding the problem of excessive incident angle caused on the inclined surface, preventing the paint from accumulating on the inclined surface, and improving the spraying quality.

[0046] 2. During the above-described working process, when the fixed plate 605 rotates, it drives the telescopic cylinder 703 to rotate, which in turn drives the telescopic rod 702 to rotate. The telescopic rod 702 then drives the support frame 701 to rotate, which in turn drives the nozzle 506 to rotate, thus adjusting the angle of the spray layer 505 and the nozzle 506. The bottom of the support frame 701 is equipped with several guide wheels. During operation, when the inclined surface of the foam board contacts the bottom of the support frame 701, the guide wheels contact the inclined surface of the foam board, causing the foam board to push the support frame 701 upwards. The support frame 701 then drives the two telescopic rods 702 to slide upwards within the corresponding telescopic cylinders 703. During this sliding process, the telescopic rods 702 compress the second spring 704. Simultaneously, the support frame 701 drives the spray layer 505 and the nozzle 506 upwards, ensuring that the height of the nozzle 506 relative to the inclined surface of the foam board remains consistent. After spraying is completed, the foam board... Separating from the support frame 701, the support frame 701 is no longer lifted. At this time, the second spring 704 pushes the telescopic rod 702 to move downward within the telescopic cylinder 703. The telescopic rod 702 drives the support frame 701 to move downward, thereby moving and resetting the spray layer 505 and the nozzle 506 downward, so that the next foam board can be sprayed. During the movement of the foam board, it pushes the elastic support component 7 to move upward, so that the output end of the spray component 5 always maintains the same height as the foam board. This can prevent uneven thickness caused by the distance between the nozzle and the foam board being too close or too far, and make the coating thickness consistent across the entire foam board surface.
