Abstract
Description
Technical Field
[0001] This utility model relates to the field of soft wall surface spraying technology, and in particular to a wall surface spraying device. Background Technology
[0002] In the process of renovating a new house, wall spraying equipment can significantly improve construction efficiency. Traditional roller or brush painting methods are time-consuming, especially when dealing with large areas of walls. They are also costly in terms of labor and prone to uneven application. Using wall spraying equipment, latex paint can be quickly and evenly sprayed onto the walls. Whether it's the living room, bedroom, kitchen, or bathroom, the spraying work can be completed in a short time, resulting in a smooth, even paint finish and enhancing the overall aesthetics of the home.
[0003] A search revealed a wall painting device (CN219622183U) disclosed in Chinese Publication No. CN219622183U. The device includes a base plate, a first motor mounted on top of the base plate, a first threaded rod fixedly connected to the power output end of the first motor, a first movable plate threadedly connected to the outer wall of the first threaded rod, a first sliding rod slidably connected to the inner wall of the first movable plate, and a vertical plate fixedly connected to one end of the first sliding rod. This device utilizes a second motor to drive the second threaded rod to rotate, which in turn drives the second movable plate to move. The second movable plate's movement direction is limited by its movement on the second sliding rod. The second movable plate adjusts the position of the spray head. Then, the first motor drives the first threaded rod to rotate, which in turn drives the first movable plate to move. The first movable plate's movement direction is limited by its movement on the first sliding rod. The first movable plate moves the spray head left and right, allowing the spray head to paint a wide area of the wall surface, thus improving painting efficiency.
[0004] The patent description mentions that "a first stirring plate and a second stirring plate are fixedly connected to the outer wall of the rotating rod in sequence." Unmixed paint contains lumps or granular substances. These lumps can clog the nozzle during spraying, preventing the paint from being sprayed evenly and resulting in uneven wall paint surfaces with defects such as pits and bumps. To address these problems, a wall painting device is proposed. Utility Model Content
[0005] The present invention proposes a wall spraying device, which aims to improve the problem that some existing wall spraying devices cannot stir and disperse raw materials.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A wall painting device includes a mounting base plate, with support rods fixedly connected to the four corners of the top left side of the mounting base plate, a top plate fixedly connected to the top of the support rods, a stirring and dispersing mechanism fixedly connected to the top of the top plate, and an adjustment mechanism fixedly connected to the top right side of the mounting base plate.
[0008] The mixing and dispersing mechanism includes a mixing tank, the outside of which is fixedly connected to the inside of the top plate. A support frame is fixedly connected to the top of the mixing tank, and a drive motor is fixedly connected to the top of the support frame. A mixing rod is fixedly connected to the drive end of the drive motor. A driving bevel gear is fixedly connected to the outside of the mixing rod. A driven bevel gear is fixedly connected to the rear side of the support frame, and a transmission assembly is fixedly connected to the outside of the driven bevel gear.
[0009] The above solution involves installing a base plate, support rods, and a top plate to form a stable frame. The mixing and dispersing mechanism on the top plate is particularly important. The mixing tank is embedded in the top plate to provide space for paint mixing. The drive motor is installed on the top of the support frame and drives the mixing rod to rotate the active bevel gear. Through meshing with the driven bevel gear, the power is transmitted to the transmission components to achieve efficient mixing and dispersing of the paint, ensuring that the paint is applied evenly and finely.
[0010] As a further description of the above technical solution:
[0011] The transmission assembly includes a transmission rod, which is fixedly connected to the outside of the driven bevel gear. A driving wheel is fixedly connected to the outside of the transmission rod, and a belt is fitted around the outside of the driving wheel. A driven rod is fixedly connected to the outside of the mixing tank, and a driven wheel is fixedly connected to the outside of the driven rod. Multiple concave cams are fixedly connected to the outside of the driven rod. A sieve plate is slidably connected inside the mixing tank.
[0012] The above scheme involves a driven bevel gear that drives a transmission rod to rotate. The driving wheel on the rod drives the driven rod via a belt, causing the driven wheel to rotate. Multiple concave cams on the driven rod continuously contact the sieve plate, pushing the sieve plate up and down within the mixing tank during rotation. This not only assists the mixing rod in fully dispersing the paint but also sieves the paint, ensuring that the sprayed paint is uniform and free of lumps.
[0013] As a further description of the above technical solution:
[0014] The mixing tank has mounting plates fixedly connected to both the front and rear sides inside. A sliding rod is fixedly connected to the outside of the mounting plate. A return spring is sleeved on the outside of the sliding rod. A limit cover is fixedly connected to the top of the sliding rod. A feed inlet is fixedly connected to the top of the mixing tank.
[0015] The above design provides support for the overall structure through the mounting plates on the front and rear sides. The sliding rod on the mounting plate is equipped with a return spring, and the top is equipped with a limit cover to form an elastic limit structure. When the screen plate slides up and down under the action of the concave cam, the return spring can buffer the impact force and assist the screen plate in resetting. The feed port at the top of the mixing tank facilitates the addition of coatings. The whole design ensures that the mixing and dispersing process is stable and efficient.
[0016] As a further description of the above technical solution:
[0017] The screen plate is internally slidably connected to the outside of the sliding rod, and the outside of the screen plate is in contact with the outside of the mounting plate.
[0018] The above solution achieves a sophisticated combination of the sieve plate, sliding rod, and mounting plate. The sieve plate can slide freely along the sliding rod, ensuring smooth vertical movement, while its external contact with the mounting plate restricts horizontal displacement, guaranteeing stable operation. When the concave cam pushes the sieve plate, the sliding rod and return spring work together to achieve reciprocating motion, effectively sieving paint and improving paint quality.
[0019] As a further description of the above technical solution:
[0020] The adjustment mechanism includes a second support frame, which is externally fixedly connected to the top right side of the mounting base plate. An installation frame is fixedly connected to the external right side of the second support frame. Limiting rods are fixedly connected to both the front and rear sides of the installation frame. A sliding plate is slidably connected to the external side of the limiting rods. An installation motor is fixedly connected to the external side of the sliding plate. A diverter plate is fixedly connected to the drive end of the installation motor.
[0021] With the above solution: Support frame 2 stands firmly on the right side of the mounting base, providing reliable support for the whole. Within the mounting frame on its right side, the front and rear limit rods plan a precise sliding track for the sliding plate, ensuring that the sliding plate moves smoothly. The mounting motor fixed on the sliding plate can be flexibly adjusted in position. The diverter plate connected to its drive end can accurately adjust the paint flow and spraying range according to different wall spraying requirements, improving the flexibility and efficiency of the operation.
[0022] As a further description of the above technical solution:
[0023] A cylinder is fixedly connected to the top of the mounting frame, and a sliding plate is fixedly connected to the driving end of the cylinder.
[0024] The above solution uses a cylinder mounted on top of the frame as the driving core. With stable air pressure, the cylinder's drive end is directly connected to the sliding plate, enabling precise lifting and lowering control of the sliding plate. By extending and retracting the cylinder, the sliding plate slides up and down along the limit rod, thereby flexibly adjusting the height of the motor and the distributor plate to meet the diverse needs of different wall heights and spraying processes, ensuring efficient and precise painting operations.
[0025] As a further description of the above technical solution:
[0026] Pump bodies are fixedly connected to both the front and rear ends of the outer right side of the mixing tank. A delivery pipe is fixedly connected to the output end of the pump body. The delivery pipe is fixedly connected to the outside of the flow divider plate. Multiple nozzles are fixedly connected to the outer right side of the flow divider plate.
[0027] The above solution utilizes pumps on both sides of the mixing tank as the power source for paint delivery. The pumps at both ends efficiently output the uniformly mixed paint through the delivery pipe and accurately transmit it to the distribution plate. The distribution plate acts as a paint distribution hub, rationally distributing the paint and evenly spraying it out through multiple nozzles on its right side. This ensures a wide coverage area and consistent paint thickness on the wall, greatly improving the uniformity of the paint application and construction efficiency.
[0028] As a further description of the above technical solution:
[0029] One end of the reset spring is fixedly connected to the bottom outer end of the mounting plate, and the other end of the reset spring is fixedly connected to the top outer end of the sieve plate.
[0030] The above solution utilizes a return spring, a key component ensuring the efficient operation of the screen plate. One end of the spring is tightly fixed to the bottom of the mounting plate, while the other end is securely connected to the top of the screen plate. When the screen plate slides down under the push of the concave cam, the return spring is compressed and stores energy. After the cam moves away, the spring quickly releases its elastic potential energy, pushing the screen plate back to its original position. This reciprocating process causes the screen plate to vibrate continuously, effectively preventing paint from clogging the screen holes and ensuring both screening efficiency and paint quality.
[0031] This utility model has the following beneficial effects:
[0032] 1. In this utility model, the driving wheel can then drive the driven rod to rotate via the belt, which in turn drives the concave cam to rotate via the driven wheel. Under the action of the concave cam, the concave cam can rotate the sieve plate, which in turn can squeeze the return spring, causing the return spring to deform and preventing the sieve plate from falling off. This process can then mix and disperse the raw materials. The mixing and dispersing can fully break down and disperse the lumps and particles in the coating, giving the coating good fluidity and fineness.
[0033] 2. In this utility model, by starting the cylinder, the cylinder can drive the sliding plate to slide inside the limit rod, and then by driving the cylinder, the cylinder can spray paint onto the nozzle through the delivery pipe. By starting the mounting motor, the mounting motor drives the diverter plate to rotate, and then the nozzle can spray paint. Attached Figure Description

[0045] Reference Figures 2 to 3The mixing and dispersing mechanism 4 includes a mixing tank 41, which serves as the core container for coating mixing. The mixing tank 41 is made of stainless steel using a plate rolling and welding process to withstand mechanical stress during mixing. The mixing tank 41 is externally fixedly connected to the inside of the top plate 3. A support frame 42 is fixedly connected to the top of the mixing tank 41, and a drive motor 43 is fixedly connected to the top of the support frame 42. A mixing rod 44 is fixedly connected to the drive end of the drive motor 43. The mixing rod 44 is forged from high-quality carbon structural steel and its surface is quenched and tempered. The upper part is connected to the shaft end of the drive motor 43, and the lower part extends into the interior of the mixing tank 41. A driving bevel gear 45 is fixedly connected to the outside of the stirring rod 44. The driving bevel gear 45 is installed in the middle of the stirring rod 44, made of alloy steel, and carburized and quenched. It is press-fitted to the stirring rod 44 using a heat-fitting process. A driven bevel gear 46 is fixedly connected to the rear side of the support frame 42, meshing perpendicularly with the driving bevel gear 45. The gear material, heat treatment, and precision grade are the same as those of the driving bevel gear 45. A transmission assembly 47 is fixedly connected to the outside of the driven bevel gear 46. The moving assembly 47 includes a transmission rod 4701, one end of which is connected to the shaft end of the driven bevel gear 46 via a key, and the other end is fitted with a driving wheel 4702 to ensure no eccentric wobbling occurs during transmission. The transmission rod 4701 is externally fixedly connected to the outside of the driven bevel gear 46, and the driving wheel 4702 is also externally fixedly connected to the transmission rod 4701. The driving wheel 4702 is made of gray cast iron and is connected to the transmission rod 4701 via a flat key. A belt 4703 is fitted around the outside of the driving wheel 4702, and the tension of the belt 4703 is adjusted by a tensioning wheel. A driven rod 4704 is fixedly connected to the outside of the mixing tank 41. The driven rod 4704 is a hollow shaft structure made of stainless steel. A driven wheel 4705 is installed at one end, and multiple concave cams 4706 are fixed at the other end. The driven wheel 4705 is fixedly connected to the outside of the driven rod 4704. The sieve plate 4707 is slidably connected to the inner wall of the mixing tank 41 through four guide sliders to ensure that the sieve plate 4707 can move up and down along the tank wall. Multiple concave cams 4706 are fixedly connected to the outside of the driven rod 4704. The sieve plate 4707 is slidably connected inside the mixing tank 41.
[0046] Specifically, the mixing tank 41 is made of stainless steel coil welded together and fixed to the top plate 3. The top support frame 42 supports the drive motor 43. The stirring rod 44 at the drive end is forged and heat-treated. The upper part is connected to the motor and the lower part extends into the tank. The driving bevel gear 45 in the middle of the stirring rod 44 meshes perpendicularly with the driven bevel gear 46 on the rear side of the support frame 42. Both are made of alloy steel carburized and quenched and have the same precision level. In the transmission assembly 47 connected to the driven bevel gear 46, one end of the transmission rod 4701 is keyed to the driven bevel gear 46 and the other end is connected to the driving wheel 4702. The driving wheel 4702 drives the driven wheel 4705 on the driven rod 4704 through the belt 4703. The driven rod 4704 is a hollow shaft structure. Multiple concave cams 4706 fixed at the other end can push the screen plate 4707 to move up and down along the inner wall groove of the mixing tank 41 to realize the stirring and dispersing of the coating.
[0047] Reference Figures 2 to 4 The mixing tank 41 has mounting plates 5 fixedly connected to both the front and rear sides inside. Four mounting holes of different diameters are evenly distributed on the surface of the mounting plates 5 for fixing the sliding rod 7, ensuring the verticality of the sliding rod 7 after installation. The sliding rod 7 is fixedly connected to the outside of the mounting plates 5, and the bottom end of the sliding rod 7 is fixedly connected to the mounting plates 5 by bolts, ensuring the sliding rod 7 is stable and does not loosen. A return spring 8 is sleeved on the outside of the sliding rod 7. In the initial state, the return spring 8 is in a pre-compressed state, providing pre-tightening force to keep the screen plate 4707 tightly against the mounting plates 5. A limit cap 6 is fixedly connected to the top of the sliding rod 7 to restrict the upward sliding of the screen plate 4707. The maximum displacement prevents the sieve plate 4707 from disengaging from the sliding rod 7. The surface of the limiting cover 6 is wire-brushed to increase friction and facilitate manual disassembly and installation. The top of the mixing tank 41 is fixedly connected to the feed inlet 10. The bottom of the feed inlet 10 is funnel-shaped and the diameter gradually expands to communicate with the inside of the mixing tank 41, so that the paint can flow smoothly into the tank and reduce residue. The inside of the sieve plate 4707 is slidably connected to the outside of the sliding rod 7. The outside of the sieve plate 4707 is in contact with the outside of the mounting plate 5. One end of the return spring 8 is fixedly connected to the bottom of the outside of the mounting plate 5, and the other end of the return spring 8 is fixedly connected to the top of the outside of the sieve plate 4707.
[0048] Specifically, the sliding rod 7 is fixed inside the mixing tank 41 by mounting plates 5 on both the front and rear sides. Four mounting holes are evenly distributed on the mounting plates 5 to ensure the sliding rod 7 is installed vertically, and its bottom end is fastened to the mounting plates 5 with bolts. A pre-compressed return spring 8 is fitted over the sliding rod 7 to provide pre-tension to the sieve plate 4707, ensuring it is tightly pressed against the mounting plates 5. The limiting cap 6 at the top of the sliding rod 7 is wire-drawn, which not only restricts the upward displacement of the sieve plate 4707 but also facilitates operation. The funnel-shaped feed inlet 10 at the top of the mixing tank 41 allows the coating to flow smoothly into the tank. The sieve plate 4707 is fitted over the sliding rod 7 and contacts the mounting plates 5. Under the action of the return spring 8, the sieve plate 4707 can slide along the sliding rod 7, working in conjunction with the mixing and dispersing mechanism to achieve effective mixing and filtration of the coating.
[0049] Working principle: By starting the drive motor 43, the drive motor 43 drives the stirring rod 44 to rotate. The stirring rod 44 then drives the driving bevel gear 45 to rotate, which in turn drives the driven bevel gear 46 to rotate. The driven bevel gear 46 then drives the driving wheel 4702 to rotate via the transmission rod 4701. The drive wheel 4702 drives the driven rod 4704 to rotate via the belt 4703. The driven rod 4704 then drives the concave cam 4706 to rotate via the driven wheel 4705. Under the action of the concave cam 4706, the concave cam 4706 can rotate the screen plate 4707, which in turn can squeeze the return spring 8, causing the return spring 8 to deform and preventing the screen plate 4707 from falling off. This allows the raw materials to be mixed and dispersed.
[0050] When adjusting the flow divider 96, the cylinder 99 is activated, causing the sliding plate 95 to slide inside the limit rod 93. This allows the cylinder 99 to spray paint onto the nozzle 97 through the delivery pipe 98. The mounting motor 94 is activated, causing it to rotate the flow divider 96, which in turn allows the nozzle 97 to spray paint.
[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
