DETAILED DESCRIPTION

[0024] See also Figures 1-6 A paint spraying device for decoration includes a cart 1, the movable wheels at the bottom of the cart 1 are self-locking movable wheels, a feeding mechanism 2 and a dust extraction mechanism 4 are provided on the top of the cart 1, a mounting shell 3 is fixed on the top of the cart 1, and a lifting mechanism 5 is provided inside the mounting shell 3;

[0025] The trolley 1 enables the device to be moved, the feeding mechanism 2 is used to transport the paint, the dust extraction mechanism 4 allows the impurities cleaned from the wall before spraying to be collected, and the lifting mechanism 5 is used to drive the nozzle 8 to adjust its height.

[0026] A mounting frame 6 is provided on one side of the mounting shell 3. A shunt pipe 7 is passed through the surface of the mounting frame 6. The shunt pipe 7 is fixedly connected to the surface of the mounting frame 6. A plurality of nozzles 8 are connected to the surface of the shunt pipe 7. An electric push rod 9 is fixed to the surface of the mounting frame 6. A collecting shell 10 is fixed to one end of the electric push rod 9. An extension plate 11 is fixed to the bottom of the collecting shell 10. A plurality of rollers 12 are rotatably connected to the surface of the extension plate 11. A scraper 13 is detachably connected to the top of the collecting shell 10.

[0027] After the trolley 1 is moved close to the wall, the telescopic length of the electric push rod 9 is adjusted according to the required distance from the wall, so that the collection shell 10 can move toward the wall surface. After moving to the required length position, the trolley 1 is pushed until the surface of the roller 12 and the surface of the scraper 13 can contact the wall surface, and then the self-locking movable wheel at the bottom of the trolley 1 is locked. At this time, the distance between the nozzle 8 and the wall can be limited, so that the nozzle 8 will not move back and forth significantly during the spraying process. Maintaining a constant spraying distance helps to ensure that the paint is distributed more evenly on the wall, thereby obtaining a consistent coating thickness. Reduce the waste of paint caused by local excessive thickness or thinness, save material costs, and the lifting mechanism 5 can drive the mounting frame 6 to move up and down, so that the nozzle 8 can spray from bottom to top, thereby increasing the spraying range. When the mounting frame 6 moves upward, the scraper 13 can first scrape the wall surface, which can help remove dust, sand, oil stains and other impurities on the wall surface. If these impurities remain on the wall, they may cause the paint to not adhere evenly, affecting the final spraying effect. During this period, the dust extraction mechanism 4 can also absorb the scraped impurities to prevent the falling impurities from being brought back into the wall surface by the paint sprayed by the nozzle 8.

[0028] The lifting mechanism 5 includes a drive motor 501, which is fixed to the top of the mounting shell 3. The output shaft of the drive motor 501 passes through the mounting shell 3 and is fixed with a screw rod 502. The bottom end of the screw rod 502 is rotatably connected to the bottom of the inner wall of the mounting shell 3. A sleeve 503 is threadedly connected to the surface of the screw rod 502. A slide groove 504 is formed on the surface of the mounting shell 3. The surface of the sleeve 503 is fixedly connected to the surface of the mounting bracket 6. The sleeve 503 and the slide groove 504 are slidably connected.

[0029] When the driving motor 501 is started, it can drive the screw rod 502 to rotate, so that the sliding sleeve 503 can be affected by the thread to start moving up and down, and the sliding sleeve 503 can also drive the mounting frame 6 to move together, thereby changing the height position of the diversion pipe 7 and the nozzle 8.

[0030] Furthermore, the feeding mechanism 2 includes a material storage box 201, which is fixed to the top of the cart 1. The surface of the material storage box 201 is connected to a delivery pump 202, which is fixedly connected to the top of the cart 1. The delivery end of the delivery pump 202 is connected to a first telescopic hose 203, and the surface of the first telescopic hose 203 is connected to the diversion pipe 7;

[0031] The interior of the storage box 201 is used to store paint. When the delivery pump 202 is started, it can extract the paint and deliver it to the inside of the diversion pipe 7 through the first telescopic hose 203, and then spray it onto the wall surface through the nozzle 8.

[0032] Furthermore, the dust extraction mechanism 4 includes an exhaust fan 401 and a treatment box 402. The exhaust fan 401 and the treatment box 402 are fixedly connected to the top of the cart 1. The surface of the exhaust fan 401 is connected to the bottom of the surface of the treatment box 402 through a pipe. The top of the treatment box 402 is connected to a second telescopic hose 403, and one end of the second telescopic hose 403 is connected to the collection shell 10.

[0033] When the exhaust fan 401 is working, it can extract the air inside the processing box 402, so that negative pressure is generated inside the processing box 402 and the second telescopic hose 403, so that the collection shell 10 can exhaust air, so that the impurities and dust scraped off the surface of the scraper 13 can be sucked into the interior of the processing box 402.

[0034] Furthermore, a U-shaped shell 404 is fixed to the inner wall of the processing box 402, a limiting groove is provided on the surface of the U-shaped shell 404, a filter 405 is slidably connected to the inner wall of the limiting groove, and a box door 406 is hinged on the surface of the processing box 402;

[0035] The filter 405 can obtain a limiting effect in the limiting groove, so that when the exhaust fan 401 is exhausting air, the filter 405 can block the extracted impurities. After opening the box door 406, the operator can directly remove the filter 405 from the inside of the processing box 402 by pulling the filter 405.

[0036] Furthermore, a connection block 14 is fixed to the surface of the scraper 13 and the surface of the collecting shell 10, and a perforation is opened on the surface of the connection block 14;

[0037] The perforated surface of the connecting block 14 allows the operator to install bolts and nuts through the perforations, thereby enabling the scraper 13 and the collecting shell 10 to be detachably connected by the bolts.

[0038] Furthermore, a slide rail 16 is fixed to the surface of the mounting shell 3, a slider 17 is slidably connected to the surface of the slide rail 16, and the slider 17 is fixedly connected to the surface of the mounting frame 6;

[0039] When the mounting frame 6 moves up and down through the lifting mechanism 5, the mounting frame 6 can drive the slider 17 to slide on the surface of the slide rail 16, so that the mounting frame 6 can obtain a linear guidance effect, thereby ensuring that the mounting frame 6 can ensure vertical movement.

[0040] Furthermore, a side block 18 is fixed to the surface of the cart 1, a screw 19 is threaded through the surface of the side block 18, a limit block 20 is fixed to the bottom of the screw 19, and a friction pad is fixed to the bottom of the limit block 20;

[0041] Rotating the screw 19 can move the limit block 20 downward so that the bottom of the friction pad can contact the ground, thereby further improving the stability of the cart 1 when it stops moving and ensuring that the cart 1 is not prone to movement during the spraying process.

[0042] Furthermore, a grid 15 is fixed to the inner wall of the collection shell 10;

[0043] The grid 15 can prevent large impurities from entering the interior of the collecting shell 10 , thereby avoiding blockage of the second telescopic hose 403 .

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
