Description

Technical Field

[0001] This invention relates to the field of wall spraying technology, and in particular to a wall decoration spraying device for building construction. Background Technology

[0002] Building construction engineering refers to the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, equipment, and interior and exterior decoration projects. "Building" refers to projects with roofs, beams, columns, walls, foundations, and the ability to form internal spaces to meet people's needs for production, living, learning, and public activities. The interior and exterior walls of buildings need to be painted according to preferences and aesthetics.

[0003] Wall decoration can be divided into paint, wallpaper, wall covering, artificial decorative panels, stone, ceramic, glass, metal, etc. The main purpose of wall decoration is to protect the wall, enhance its strength and durability, extend its service life, improve its functionality, enhance its heat insulation, sound insulation and heat insulation capabilities, improve the artistic effect of the building, and beautify the environment.

[0004] When spraying paint on walls, it is usually done manually or with a small spray gun. However, manual paint roller application or handheld spray gun application is laborious, and spraying high-positioned walls can be difficult. Furthermore, moving the spray gun while supported by a stand is even more challenging, affecting the overall spraying efficiency. Paint residue remains on the nozzle surface after spraying, and this residue can solidify over time, causing blockages and affecting the spraying effect later. Therefore, a wall decoration spraying device for building construction is needed to solve these problems. Summary of the Invention

The adjustment gear and the incomplete gear mesh with each other. The adjustment gear is slidably connected to the surface of the rotating rod.

[0010] The cleaning assembly includes a fixed rod and a limiting rod fixedly connected inside the fixed box. A sliding sleeve is slidably connected to the surface of the fixed rod, and a limiting sleeve is slidably connected to the surface of the limiting rod.

A cleaning brush is fixedly connected to the side of the mounting plate that is close to the spray plate. A compression spring with one end fixedly connected to the sliding sleeve is sleeved on the surface of the fixed rod.

[0011] As a further improvement to the above solution, the lifting assembly also includes a drive motor fixedly connected inside the extension seat. The output end of the drive motor is fixedly connected to an adjusting screw. An adjusting screw groove is opened inside the lifting rod. The top end of the adjusting screw is threadedly connected to the inside of the adjusting screw groove. Limiting protrusions are fixedly connected to both sides inside the fixed tube.

[0012] As a further improvement to the above solution, the adjustment assembly includes a first gear fixedly connected to the surface of the adjustment screw, and a second gear fixedly connected to the surface of the rotating rod, wherein the first gear and the second gear mesh with each other.

[0013] As a further improvement to the above solution, the cleaning component includes a mounting screw hole opened inside the extension rod, and a mounting screw is fixedly connected to the side of the mounting plate near the extension rod.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The height of the spraying component is adjusted by the lifting component, which facilitates spraying paint from low to high on wall surfaces of different lengths. When the lifting component is activated, it drives the adjustment component to rotate, thereby allowing the spraying component to rotate left and right. With the torsion spring resetting, the spraying component can rotate left and right for spraying, allowing for faster spraying of a wider range of wall decorations.

[0020] 2. By manually pushing the cleaning component back and forth across the surface of the spray plate, residual paint on multiple nozzles on the spray plate surface can be cleaned. The cleaning brush is reset by the pushing force of the compression spring. As the cleaning brush moves back and forth across the surface of multiple nozzles, the reciprocating movement of the cleaning brush cleans the nozzle surface more thoroughly, preventing paint from solidifying on the nozzle surface and causing some nozzles to become clogged, thus affecting the spraying effect.

[0021] 3. The mounting screw holes and screw rods facilitate quick replacement of the cleaning brush and mounting plate. Regular replacement of the cleaning brush ensures optimal cleaning performance. The repeated sliding of the cleaning brush against the nozzle surface effectively removes residual paint, thus improving the cleaning effect. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0039] Please see Figures 1 to 9 The present invention provides an embodiment of a wall decoration spraying device for building construction, comprising a base 1, a storage box 2, and an extension seat 3. The storage box 2 is placed on the upper surface of the base 1, and the end of the extension seat 3 near the base 1 is fixedly connected to the side surface of the base 1. A spraying component for spraying paint is provided between the upper surface of the base 1 and the storage box 2. A lifting component for adjusting the height of the spraying component is provided on the top of the extension seat 3, and an adjustment component for adjusting the angle is provided on the top of the extension seat 3. A cleaning component for cleaning the surface of the spraying component is provided on the side of the spraying component away from the spraying component.

[0040] The spraying assembly includes a discharge pipe 401 fixedly connected to the storage tank 2 near the extension seat 3. A paint pump 402 is fixedly connected to the upper surface of the base 1. The end of the discharge pipe 401 near the paint pump 402 is fixedly connected to the paint pump 402. A telescopic hose 403 is fixedly connected to the side of the paint pump 402 away from the discharge pipe 401. A support frame 404 is fixedly connected to the end of the telescopic hose 403 away from the paint pump 402. A spraying plate 405 is fixedly connected to the end of the support frame 404 away from the telescopic hose 403. A nozzle 406 is provided on the side of the spraying plate 405 away from the support frame 404. A fixed box 407 is fixedly connected to the top of the nozzle 406. The end of the telescopic hose 403 away from the paint pump 402 passes through the interior of the spraying plate 405.

[0041] Specifically, the suction of the paint pump 402 allows the paint inside the storage tank 2 to enter the interior of the spray plate 405 through the telescopic hose 403, thereby spraying the paint through the nozzle 406. The support frame 404 is used to support one end of the telescopic hose 403. The telescopic hose 403 is flexible and foldable, so it can stretch and contract during lifting and lowering. This allows the telescopic hose 403 to stretch and move when spraying paint at different heights, making it easier to spray paint at different heights.

[0042] The lifting assembly includes a fixed tube 501 fixedly connected to the upper surface of the extension seat 3, a lifting rod 504 slidably connected inside the fixed tube 501, an adjusting rod 506 rotatably connected to the end of the lifting rod 504 away from the extension seat 3, a support plate 507 fixedly connected to the end of the adjusting rod 506 away from the lifting rod 504, and the bottom of the support frame 404 fixedly connected to the surface of the support plate 507.

[0043] The lifting assembly also includes a drive motor 502 fixedly connected inside the extension seat 3. An adjusting screw 503 is fixedly connected to the output end of the drive motor 502. An adjusting screw groove 505 is opened inside the lifting rod 504. The top end of the adjusting screw 503 is threadedly connected inside the adjusting screw groove 505. Limiting protrusions 508 are fixedly connected to both sides inside the fixed tube 501. Limiting grooves 509 are opened on both sides of the outer surface of the lifting rod 504. The end of the limiting protrusion 508 away from the fixed tube 501 is slidably connected inside the limiting groove 509.

[0044] Specifically, starting the drive motor 502 causes the adjusting screw 503 to rotate. Under the action of the screw thread and the limiting protrusion 508 and the limiting slide groove 509 limiting the lifting rod 504, the lifting rod 504 can be pushed to maintain vertical reciprocating sliding. The lifting of the lifting rod 504 can adjust the height of the spraying assembly, allowing the spraying assembly to spray wall decorations at different heights. The limiting protrusion 508 and the limiting slide groove 509 ensure that the lifting rod 504 slides vertically, thus facilitating the spraying of paint on the wall decorations at different heights.

[0045] The adjustment assembly includes a support frame 601 fixedly connected to the upper surface of the extension seat 3. A rotating rod 603 is rotatably connected inside both the support frame 601 and the extension seat 3. A fixed sliding plate 608 is fixedly connected to the side of the lifting rod 504 near the rotating rod 603. The rotating rod 603 passes through the interior of the fixed sliding plate 608. An adjusting gear 605 is provided on the surface of the rotating rod 603. An incomplete gear 606 is fixedly connected to the surface of the adjusting rod 506. A torsion spring 607 is provided on the surface of the adjusting rod 506 between the support plate 507 and the incomplete gear 606. The adjusting gear 605 meshes with the incomplete gear 606. The adjusting gear 605 is slidably connected to the surface of the rotating rod 603.

[0046] The adjustment assembly includes a first gear 602 fixedly connected to the surface of the adjustment screw 503, and a second gear 604 fixedly connected to the surface of the rotating rod 603. The first gear 602 and the second gear 604 mesh with each other.

[0047] The rotating rod 603 is cross-shaped, and the arc surface of the incomplete gear 606 is fixedly connected with protruding teeth;

[0048] The rotating rod 603, the fixed slide plate 608 and the adjusting gear 605 are all located inside the support frame 601, and the bottom of the adjusting gear 605 is rotatably connected to the upper surface of the fixed slide plate 608.

[0049] Specifically, the rotation rod 603 and adjusting gear 605 can be rotated by the power transmitted through gear 602 and gear 604. During the rotation of adjusting gear 605 and incomplete gear 606, the adjusting rod 506, support plate 507, and spraying assembly can be rotated at different angles. This facilitates the spraying of paint onto the wall decoration at different angles. When adjusting gear 605 rotates, it drives incomplete gear 606 to rotate. When the side of incomplete gear 606 without teeth rotates to the side of adjusting gear 605, the teeth of adjusting gear 605 are not present. When the corresponding teeth are engaged, the gear will rotate continuously. When the incomplete gear 606 is not driven, the torque of the torsion spring 607 drives the incomplete gear 606 to rotate in the opposite direction and reset. This causes the toothed side of the incomplete gear 606 to rotate to the side of the adjusting gear 605, so that the teeth of the adjusting gear 605 can mesh with the teeth of the incomplete gear 606. This allows the adjusting rod 506, the support plate 507, and the spraying assembly to reciprocate, which facilitates the reciprocating spraying effect of the spraying assembly and increases the spraying range of the wall decoration.

[0050] The cleaning assembly includes a fixed rod 701 and a limiting rod 702 fixedly connected inside the fixed box 407. A sliding sleeve 703 is slidably connected to the surface of the fixed rod 701, and a limiting sleeve 704 is slidably connected to the surface of the limiting rod 702. A connecting rod 705 is fixedly connected to the side of the sliding sleeve 703 and the limiting sleeve 704 that are close to each other. An extension rod 706 is fixedly connected to the side of the sliding sleeve 703 that is away from the connecting rod 705. An installation plate 707 is provided at the end of the extension rod 706 that is away from the sliding sleeve 703. A cleaning brush 708 is fixedly connected to the side of the installation plate 707 that is close to the spray plate 405. A compression spring 709 with one end fixedly connected to the sliding sleeve 703 is sleeved on the surface of the fixed rod 701.

[0051] The cleaning assembly includes a mounting screw hole 710 opened inside the extension rod 706, and a mounting screw 711 is fixedly connected to the side of the mounting plate 707 near the extension rod 706. The end of the mounting screw 711 away from the mounting plate 707 is threaded into the interior of the mounting screw hole 710.

[0052] The side of the cleaning brush 708 away from the mounting plate 707 abuts against the surface of the spray plate 405 and the nozzle 406;

[0053] Specifically, the cleaning brush 708 of the cleaning component repeatedly wipes the multiple nozzles 406 on one side of the spray plate 405, thereby cleaning the paint residue on the edge of the nozzles 406 and preventing the residual paint from remaining for a long time and hardening. Hardened paint can clog the nozzles 406 and affect the subsequent paint spraying effect. The compression force of the compression spring 709 can easily reset the pulled cleaning brush 708, and the wiping effect is repeated while resetting.

[0054] Reference Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, a sliding opening 8 is provided on the side of the fixed box 407 away from the support plate 507, and the end of the extension rod 706 away from the sliding sleeve 703 is slidably connected to the inside of the sliding opening 8.

[0055] Specifically, the sliding opening 8 on one side of the fixed box 407 facilitates the reciprocating sliding of the extension rod 706.

[0056] Based on the above preferred embodiments, the working principle of the present invention is as follows:

[0057] In the initial state, the fixed box 407 and the spray plate 405 are in a neutral position, the lifting rod 504 is in the lowest position, the adjusting gear 605 and the incomplete gear 606 are in a tooth-to-tooth meshing state, the torsion spring 607 is in a normal state, and the compression spring 709 inside the fixed box 407 is not compressed.

[0058] During work:

[0059] During the process of spraying wall decorations at different heights, the worker starts the drive motor 502, which drives the adjusting screw 503 to rotate. Due to the threaded connection between the adjusting screw 503 and the adjusting screw groove 505, the adjusting screw 503 and the adjusting screw groove 505, as well as the limiting protrusion 508 and the limiting slide groove 509, limit the sliding of the lifting rod 504. This allows the lifting rod 504 to slide inside the fixed tube 501. The limiting protrusion 508 and the limiting slide groove 509 limit the vertical sliding of the lifting rod 504, enabling it to maintain a vertical sliding effect. When the lifting rod 504 slides up and down, it can push the fixed slide plate 608, adjusting rod 506, support plate 507, fixed support frame 404, and spray plate 405 to slide up and down, thereby enabling the spraying components to slide up and down and spray paint at different heights of the wall decoration.

[0060] While the adjusting screw 503 rotates, the first gear 602 on the surface of the adjusting screw 503 also rotates simultaneously. The first gear 602 and the second gear 604 are meshed. The rotation of the first gear 602 drives the meshing second gear 604 to rotate. Since the second gear 604 is fixed to the surface of the rotating rod 603, the rotation of the rotating rod 603 is driven by the transmission action of the first gear 602 and the second gear 604. Because the rotating rod 603 is cross-shaped, its rotation, limited by the cross shape itself, drives the adjusting gear 605 to rotate synchronously. The bottom of the adjusting gear 605 is... The top of the fixed sliding plate 608 is rotatably connected, and the fixed sliding plate 608 supports the adjusting gear 605. This allows the adjusting gear 605 to slide synchronously up and down with the lifting rod 504 as the lifting rod 504 slides up and down, ensuring that the adjusting gear 605 and the incomplete gear 606 remain on the same horizontal line. The adjusting gear 605 slides up and down while rotating on the surface of the rotating rod 603. The rotation of the rotating rod 603 drives the adjusting gear 605 to rotate, and the adjusting gear 605 meshes with the incomplete gear 606. The teeth of the adjusting gear 605 engage with... When the teeth of the incomplete gear 606 mesh, it drives the incomplete gear 606, adjusting rod 506, torsion spring 607, and fixed spraying assembly to rotate simultaneously. Simultaneously, the torsion spring 607 on the surface of the adjusting rod 506 twists in the opposite direction of torque, causing the torsion spring 607 to open. However, because the incomplete gear 606 has incomplete teeth, as the adjusting gear 605 continues to rotate, the toothless side of the incomplete gear 606 rotates to the side of the adjusting gear 605. When the adjusting gear 605 is not meshing, the incomplete gear 606, adjusting rod 506, and support plate 507... The spraying assembly will stop rotating. At the same time, without the restriction of rotational force, the torsion spring 607 will return to its original position due to its own torque. This torque will drive the incomplete gear 606 to rotate in the opposite direction, causing the toothed side of the incomplete gear 606 to rotate back and return to the state of meshing with the teeth of the adjusting gear 605. This will enable the support plate 507 and the spraying assembly to rotate in the opposite direction, thus enabling the support plate 507 and the spraying assembly to reciprocate and rotate, which can quickly expand the range of wall decoration spraying.

[0061] During the lifting and lowering of the spraying assembly, when adjusting the angle, the worker starts the paint pump 402 to spray the wall decoration. The paint pump 402 generates suction, which draws the evenly mixed paint from the storage tank 2 into the telescopic hose 403 through the discharge pipe 401. The paint is then drawn into the spraying plate 405 through the telescopic hose 403. Multiple nozzles 406 on one side of the spraying plate 405 spray the paint out. The support frame 404 supports one end of the telescopic hose 403. The telescopic hose 403 is flexible and foldable, allowing it to stretch and contract during lifting and lowering. This facilitates the even spraying of paint onto the wall decoration surface. The wall decoration can be sprayed from low to high. By rotating the angle of the spraying assembly, the spraying area can be expanded, allowing for faster completion of the wall decoration spraying.

[0062] After the wall decoration paint is applied, the worker manually pulls one end of the mounting plate 707 to slide it to the other end. This causes the extension rod 706, sliding sleeve 703, connecting rod 705, and limiting sleeve 704 to slide. The sliding sleeve 703 and limiting sleeve 704 slide on the surfaces of the fixed rod 701 and the limiting rod 702. The limiting sleeve 704, sliding on the surface of the limiting rod 702, serves to horizontally limit the sliding of the mounting plate 707 and the cleaning brush 708. When the sliding sleeve 703 slides, it drives the fixed rod 701 on one side... The extension rod 706 of the fixed connection slides synchronously. When the extension rod 706 slides, under the connection of the mounting screw hole 710 and the mounting screw 711, it will drive the mounting plate 707 and the cleaning brush 708 to slide on the surface of the spray plate 405. When the cleaning brush 708 and the mounting plate 707 slide, they can clean the paint residue of multiple nozzles 406 on the surface of the spray plate 405. When the sliding sleeve 703 slides on the surface of the fixed rod 701, it will compress the compression spring 709 set on the surface of the fixed rod 701. When compressed, 709 generates a compressive thrust. Without a limiting force on the compression spring 709, this thrust can push the sliding sleeve 703 back to its original position. When the sliding sleeve 703 returns to its original position, it can drive the extension rod 706, mounting plate 707, and cleaning brush 708 back to their original positions. As the cleaning brush 708 and mounting plate 707 return to their original positions, they clean the multiple nozzles 406 on the surface of the spray plate 405 again, preventing paint residue from remaining on the nozzles 406 and causing blockages, thus avoiding affecting the subsequent paint spraying effect. The operator holds the mounting plate 707 and the cleaning brush 708 and rotates them. When the mounting plate 707 rotates, it drives the fixed mounting screw 711 to rotate, so that the mounting screw 711 is close to one end of the extension rod 706. Under the action of the thread, the mounting screw 711 is threaded into the inside of the mounting screw hole 710. Thus, the cleaning brush 708 and the mounting plate 707 can be quickly replaced through the mounting screw hole 710 and the mounting screw 711, avoiding the impact on the cleaning effect of residual paint on the surface of the nozzle 406 if they are not replaced for a long time.
