Description

Technical Field

[0001] The present invention relates to the field of decoration, and in particular to an efficient environmentally friendly paint spraying device for building decoration. Background Art

[0002] Common interior walls are often finished with wall paint or wallpaper. When using wall paint, it's usually applied by brushing or spraying. Spraying creates a more aesthetically pleasing finish without brush marks, while some paints only achieve their best results with spraying. Conventional paint sprayers typically use a pump to deliver paint to a nozzle, which then atomizes the paint and sprays it out. Since the nozzle sprays out dispersed granular droplets, and the sprayed droplets are at a certain distance, in order to ensure that all parts of the wall are sprayed, it is generally necessary to repeat the spraying or move the nozzle back and forth in a small range in the spraying area. In particular, the conventional paint spraying devices used in interior decoration are mostly controlled by hand-held means. Such operation is time-consuming, labor-intensive and inefficient. Moreover, the speed of the nozzle movement, the size of the distance between the nozzle and the wall, the angle between the spray direction and the wall, etc. all directly affect the uniformity of the sprayed paint, and hand-held operation is difficult to accurately control. In addition, during the spraying process, part of the atomized paint will diffuse into the air, polluting the air at the construction site and having a greater impact on the health of the workers at the construction site. Summary of the Invention

[0003] The purpose of the present invention is to provide an efficient and environmentally friendly paint spraying device for building construction and decoration to solve the problem that the prior art is time-consuming and labor-intensive to operate.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A high-efficiency environmentally friendly paint spraying device for building construction and decoration, including a sprayer, which includes a sprayer body and a nozzle, and also includes a vibration mechanism. The vibration mechanism includes a mounting frame, a vibration frame slidably connected to the mounting frame, a vibration gear rotatably connected to the mounting frame, and a vibration motor that drives the vibration gear to rotate. The vibration frame slides in a horizontal direction and the sliding direction is perpendicular to the spraying direction of the nozzle. The vibration frame includes two parallel and oppositely arranged vibration racks and a connecting bar connecting the two vibration racks. The vibration rack is arranged along the sliding direction of the vibration frame. The vibration gear is evenly provided with gear teeth on only half of its circumference. The rotation axis of the vibration gear is parallel to the spraying direction of the nozzle. The vibration gear is located between the two vibration racks. The vibration gear can engage with the two vibration racks and can only engage with one of the vibration racks at the same time. The nozzle is fixedly arranged on the vibration frame.

[0006] By adopting the above technical solution, the structure in which only part of the vibration gear has gear teeth is utilized, so that the vibration gear can engage with two vibration racks in succession when rotating. When engaging with different vibration racks, the vibration frame translates horizontally in opposite directions, so that the nozzle on the vibration frame can vibrate back and forth, thereby achieving a small range of movement while the nozzle is spraying, so that the spraying is uniform. There is no need to manually move the nozzle to make such movements, nor is there any need to repeatedly spray the same area, which helps to save spraying time, save manpower, and improve spraying efficiency.

[0007] Preferably, at least two nozzles are evenly arranged along the sliding direction of the vibration frame.

[0008] By adopting the above technical solution, setting up multiple nozzles can increase the spraying area and improve efficiency. The nozzles are set along the sliding direction of the vibration frame. When the vibration frame moves back and forth, the nozzles move, and the spraying range moves accordingly, which can better cover the connection between the spraying ranges of adjacent nozzles, helping to improve the uniformity of the spraying.

[0009] Preferably, a shielding cover is detachably fixedly connected to the mounting frame, and the shielding cover is trumpet-shaped, and its larger opening is rectangular. The paint outlet of the nozzle passes through the smaller opening of the shielding cover and faces the larger opening of the shielding cover. The movable spraying range of the nozzle covers the larger opening of the shielding cover. A shielding plate is fixedly provided on the nozzle, and the shielding plate blocks the smaller opening from outside the shielding cover.

[0010] With this technical solution, the nozzle sprays within the shield, which confines most of the atomized paint between the shield and the wall, helping to reduce contamination of the construction site and contribute to environmental protection. Furthermore, the shield confines the spraying area to the shape of its larger opening, creating a clear and regular spray range and making it easier to locate the equipment when spraying adjacent walls. A baffle can also reduce or prevent paint from escaping the shield's smaller opening and dispersing into the air.

[0011] Preferably, the vibration frame and the mounting frame are slidably connected via slide grooves and pulleys respectively provided on the two. The vibration frame is provided with a slide groove, and the mounting frame is rotatably connected with a pulley. The pulley is adapted to the slide groove and is located in the slide groove.

[0012] By adopting the above technical solution and arranging pulleys and slide grooves, the resistance of the reciprocating movement of the vibration frame can be reduced, which helps to save energy.

[0013] Preferably, it also includes a frame and a lifting device, the lifting device includes a support frame 1 fixedly connected to the frame, a lifting platform 1 slidably connected to the support frame 1, a driving device 1 for driving the lifting platform 1 to slide up and down, a support frame 2 fixed on the lifting platform 1, a lifting platform 2 slidably connected to the support frame 2, and a driving device 2 for driving the lifting platform 2 to slide up and down, and the vibration mechanism is arranged on the lifting platform 2.

[0014] By adopting the above technical solution, setting up a frame and a lifting device can replace the manual handheld nozzle, which helps to save effort. In addition, it is convenient to ensure that the spraying direction of the nozzle remains perpendicular to the wall being sprayed. The lifting device can make the nozzle move up and down at a relatively stable speed, which helps to spray evenly. The lifting device has a two-stage structure, which can ensure the spraying height of the nozzle while facilitating the device to enter the room.

[0015] Preferably, the mounting bracket and the second lifting platform are hinged by a horizontal hinge shaft, and the hinge shaft is perpendicular to the spraying direction of the nozzle. A horizontal limit locking assembly and a vertical limit locking assembly are provided between the mounting bracket and the second lifting platform; when the horizontal limit locking assembly locks the relative position of the mounting bracket and the second lifting platform, the paint outlet of the nozzle faces forward; when the vertical limit locking assembly locks the relative position of the mounting bracket and the second lifting platform, the paint outlet of the nozzle faces directly upward.

[0016] By adopting the above technical solution, the direction of the nozzle can be changed by rotating so that the nozzle can adapt to the spraying of the roof. The horizontal limit locking component and the vertical limit locking component are provided to keep the direction of the nozzle stable.

[0017] Preferably, the mounting frame includes a connecting plate, a support rod and a connecting frame, the vibration motor and the vibration gear are respectively arranged on both sides of the connecting plate, the support rod is parallel to the output shaft of the vibration motor, four support rods are provided and are evenly distributed around the vibration motor, the connecting frame is rhombus-shaped and each end point is fixedly connected to one end of a support rod away from the connecting plate, the hinge shaft is arranged at one end of the support rod close to the connecting frame, the horizontal limit locking assembly includes a limit rod fixedly arranged on the lifting platform 2, when the paint outlet of the nozzle is facing forward, the support rod connected to the hinge shaft abuts against the limit rod, the vertical limit locking assembly includes a limit frame fixedly arranged on the lifting platform 2, when the paint outlet of the nozzle is facing upward, the connecting frame abuts against the limit frame.

[0018] By adopting the above technical solution, the limited rotation range of the support rod and the limit rod is utilized to facilitate the quick determination of the position of the mounting bracket when the nozzle is facing forward, and the limited rotation range of the connecting frame and the limit rack is utilized to facilitate the quick determination of the position of the mounting bracket when the nozzle is facing upward. In addition, the support rod can protect the vibration motor from bumps, and the connecting frame can strengthen the support rod.

[0019] Preferably, the horizontal limit locking assembly also includes a magnetic assembly one, and the two magnetic parts of the magnetic assembly one are respectively arranged at the contact points between the limit rod and the support rod. The vertical limit locking assembly also includes a magnetic assembly two, and the two magnetic parts of the magnetic assembly two are respectively arranged at the contact points between the limit frame and the connecting frame.

[0020] By adopting the above technical solution, the magnetic suction component can lock the corresponding structure when the support rod and the limit rod are in contact, and when the connecting frame and the limit frame are in contact, which helps to keep the nozzle stable.

[0021] Preferably, the hinge shaft is fixed to the mounting frame, a flip gear is coaxially fixed to the free end of the hinge shaft, a flip rack is fixedly connected to the top of the second support frame, the flip rack is adapted to the flip gear, and when the mounting frame rises until the flip gear contacts the flip rack, the flip rack engages with the flip gear.

[0022] By lifting and lowering the mounting frame, the flip gear can be engaged with the flip rack at the top of the supporting frame 2, so that it can rise and fall through the lifting frame 2, driving the flip gear to move up and down while engaging with the flip rack, so that the flip gear rotates and drives the mounting frame to rotate, changing the direction of the nozzle.

[0023] Preferably, it also includes a walking mechanism, which includes a front and rear walking assembly, a left and right walking assembly, a universal walking assembly and a switching assembly, the front and rear walking assembly includes a wheel frame 1 and front and rear walking wheels rotatably connected to the wheel frame 1, the axis of the rotating shaft of the front and rear walking wheels is horizontal and perpendicular to the sliding direction of the vibration frame, the left and right walking assembly includes a wheel frame 2 and left and right walking wheels rotatably connected to the wheel frame 2, the axis of the rotating shaft of the left and right walking wheels is horizontal and parallel to the sliding direction of the vibration frame, the wheel frame 1 and the wheel frame 2 are arranged under the frame and are respectively connected to the frame The frame is connected for sliding in the vertical direction, and the switching assembly includes a bidirectional screw that is vertically rotatably connected to the bottom of the frame, and wheel frame one and wheel frame two are respectively threadedly connected to two sections of threads of the bidirectional screw with opposite rotation directions, and the universal travel assembly includes a plurality of universal wheels arranged at the bottom of the frame; when the lowest points of the front and rear travel wheels and the left and right travel wheels are at the same height, and the lowest points of the front and rear travel wheels are higher than the lowest point of the universal wheels, there is a gap between wheel frame one and wheel frame two; when the front and rear travel wheels and the left and right travel wheels are farthest away from each other, the lower lowest point of the two is lower than the lowest point of the universal wheels.

[0024] The above technical solution provides three types of wheels for different scenarios. The left and right running wheels can be used to move the device parallel to the wall after a lift and spray operation. The left and right running wheels constrain the device to move in a straight line, maintaining the distance between the wall and the nozzle, ensuring uniform spraying in adjacent areas. The front and rear running wheels constrain the forward direction when adjusting the nozzle-wall distance, ensuring a constant angle between the nozzle and the wall. This reduces the need for adjusting the device's orientation, saving time and effort. The left and right running wheels and the front and rear running wheels can also maintain linear horizontal or vertical movement when spraying roofs, reducing operational complexity and facilitating uniform spraying. The universal wheels are used to reposition the device when not spraying, facilitating its maneuverability according to terrain. A switching assembly adjusts the relative heights of the left and right running wheels and the front and rear running wheels, as well as the relative heights of the two running wheels and the universal wheels, by rotating a bidirectional screw, ensuring that all three wheels are at their lowest position, thus enabling the corresponding wheels to enter operation.

[0025] The present invention has the following beneficial effects:

[0026] The high-efficiency environmentally friendly paint spraying device for building construction and decoration of the present invention can be well adapted to indoor wall and roof spraying, has high spraying efficiency, good spraying uniformity and effect, and helps to reduce air pollution at the construction site caused by spraying.

[0045] The frame 100 includes a base plate 110 and a handle 120 fixed to the base plate 110. The lifting device includes a support frame 1 260 fixedly connected to the base plate 110, a lifting platform 1 250 slidably connected to the support frame 1 260, a driving device 1 for driving the lifting platform 1 250 to slide up and down, a support frame 220 fixed to the lifting platform 1 250, a lifting platform 210 slidably connected to the support frame 220, and a driving device 2 for driving the lifting platform 210 to slide up and down. The support frame 260 includes three support guide rods 261 vertically fixed on the base plate 110 and a U-shaped top rod 262 connected to the top of the three support guide rods 261. The three support guide rods 261 pass through the lifting platform 250 and are slidably connected to the lifting platform 250. The driving device 1 includes a screw rod 270 whose two ends are respectively rotatably connected to the base plate 110 and the top rod 262, and a driver 1 that drives the screw rod 270 to rotate. The driver 1 is fixedly connected to the base plate 110. The support frame 220 includes three support guide rods 221 vertically fixed on the lifting platform 1 250 and a U-shaped top rod 222 connected to the top of the three support guide rods 221. The three support guide rods 221 pass through the lifting platform 210 and are slidably connected to the lifting platform 210. The driving device 2 includes a screw rod 230 whose two ends are respectively connected to the bottom plate 110 and the top rod 222, and a lifting motor 240 that drives the screw rod 230 to rotate. The lifting motor 240 is fixedly connected to the lifting platform 1 250. The openings of the top rod 1 262 and the top rod 222 face the same direction. For the convenience of subsequent description, this direction is recorded as the front of the device. The driver and the screw rod can be directly connected or transmitted through a transmission structure. In this embodiment, a belt transmission structure is used for transmission.

[0046] like Figure 3 river Figure 4As shown, the vibration mechanism 300 includes a mounting frame 310, a vibration frame 320, a vibration gear 330 and a vibration motor 340. The vibration gear 330 is evenly provided with gear teeth only on half of its circumference. The mounting frame 310 is frame-shaped and includes a connecting plate 311, four support rods 312 and a connecting frame 313. The connecting plate 311 and the connecting frame 313 are arranged in parallel. Four support rods 312 are arranged and perpendicular to the connecting plate 311. The two ends of the support rods 312 are respectively fixedly connected to the connecting plate 311 and the connecting frame 313. The connecting frame 313 is diamond-shaped. The four support rods 312 are respectively connected to the four end points of the connecting frame 313. The vibration motor 340 is fixedly set in the frame of the mounting frame 310. The output end of the vibration connection passes through the connecting plate 311 and is coaxially fixed to the vibration gear 330. The support rods 312 are evenly distributed around the vibration motor 340. Two of the support rods 312 are in the same plane as the output shaft of the vibration motor 340 and are respectively located on the left and right sides of the vibration motor 340. The output shaft of the vibration motor 340 is parallel to the support rods 312. The vibration frame 320 is a rectangular frame comprising two parallel, opposing vibration racks 321 and two connecting bars 322, one connecting each end of the two vibration racks 321. The vibration racks 321 are arranged horizontally. The vibration frame 320 is parallel to and slidably connected to the connecting plate 311. A vibration gear 330 is located between the two vibration racks 321. The vibration gear 330 can mesh with both vibration racks 321, but can only mesh with one of the racks 321 at a time. Continuous rotation of the vibration gear 330 drives the vibration frame 320 to reciprocate horizontally. The two vibrating racks 321 are provided with a slide groove 323 arranged along the length direction of the racks on the side facing the connecting plate 311. The connecting plate 311 is rotatably connected to the side away from the connecting frame 313 with four pulleys 314. Two pulleys 314 are provided in the slide groove 323 of each vibrating rack 321. The pulleys 314 are adapted to the slide groove 323 and can move back and forth along the slide groove 323. The slide groove 323 can also be set on the mounting frame 310 and the pulley 314 can be set on the vibration frame 320.

[0047] Combine Figure 4 and Figure 5As shown, the mounting frame 310 is mounted on the lifting platform 210. The mounting frame 310 can be fixed on the lifting platform 210, but in order to take into account the spraying of the indoor wall facade and the roof surface at the same time, the mounting frame 310 is preferably hinged to the lifting platform. In this embodiment, a hinged connection is adopted. A hinge seat 211 is provided on the lifting platform 210, and the mounting frame 310 is connected to the hinge seat 211 via a hinge shaft 510. There are two hinge shafts 510 and they are respectively arranged on two support rods 312 located on the left and right sides of the vibration motor 340. The two hinge shafts 510 are coaxially arranged and located at one end of the support rod 312 near the connecting frame 313. The hinge shaft 510 is horizontal and perpendicular to the support rod 312 to which it is connected. For the convenience of subsequent description, the state of the vibration mechanism 300 when the output end of the vibration motor 340 is horizontal and facing forward is recorded as the horizontal working state, and the state of the vibration mechanism 300 when the output end of the vibration motor 340 is vertical and facing upward is recorded as the vertical working state. A horizontal limit locking assembly 520 for locking the vibration mechanism 300 in a horizontal operating state and a vertical limit locking assembly 530 for locking the vibration mechanism 300 in a vertical operating state are provided between the mounting frame 310 and the lifting platform 210. The horizontal limit locking assembly 520 includes a limit rod 521 fixedly mounted on the hinge frame and a magnetic assembly 1 522. When the vibration mechanism 300 is in the horizontal operating state, the support rod 312 connected to the hinge shaft 510 abuts against the limit rod 521. The two magnetic components of the magnetic assembly 1 522 are respectively fixedly mounted at positions where the limit rod 521 and the support rod 312 can contact each other. When the vibration mechanism 300 is in the horizontal operating state, the two magnetic components of the magnetic assembly 1 522 are attracted to each other. The vertical limit locking assembly 530 includes a limit frame 531 fixedly arranged on the hinged frame and a magnetic assembly 2 532; when the vibration mechanism 300 is in the vertical working state, the side of the connecting frame 313 away from the connecting plate 311 abuts against the limit frame 531; the two parts of the magnetic components of the magnetic assembly 2 532 are respectively fixedly arranged at positions where the limit frame 531 and the connecting frame 313 can contact each other, and when the vibration mechanism 300 is in the vertical working state, the two parts of the magnetic components of the magnetic assembly 2 532 are attracted.

[0048] In order to facilitate the switching of the vibration mechanism 300 between the horizontal and vertical working states, one of the hinge shafts 510 can be fixed to the mounting frame 310 and pass through the hinge seat 211. The free end of the hinge shaft 510 is coaxially fixed with a flip gear 541, and the top of the support frame 220 is fixedly connected with a flip rack 542. The flip rack 542 is adapted to the flip gear 541. When the mounting frame 310 rises until the flip gear 541 contacts the flip rack 542, the flip rack 542 engages with the flip gear 541, and the working state of the vibration mechanism 300 is converted by the vibration mechanism 300 rising and falling.

[0049] like Figure 1 and2 As shown, the sprayer includes a spray head 401 and a sprayer body 402. The sprayer body 402 includes a delivery pump and a paint storage cylinder. The inlet end of the delivery pump is connected to the paint storage cylinder, and the outlet end of the delivery pump is connected to the paint inlet end of the spray head 401 through a high-pressure hose. The sprayer can use an existing device on the market. The sprayer body 402 can be set on the base plate 110, or it can be set separately from the frame 100. In this embodiment, the sprayer is set on the base plate 110. The spray head 401 is fixedly set on the vibration frame 320. The spraying direction of the spray head 401 is parallel to the output shaft of the vibration motor 340 and the paint outlet of the spray head 401 is facing away from the mounting frame 310. That is, when the vibration mechanism 300 is in a horizontal working state, the paint outlet of the spray head 401 faces forward; when the vibration mechanism 300 is in a vertical working state, the paint outlet of the spray head 401 faces directly upward. At least two nozzles 401 are provided along the sliding direction of the vibration frame 320 . When three or more nozzles 401 are provided, the intervals between adjacent nozzles 401 are uniform. In this embodiment, two nozzles 401 are provided.

[0050] like Figure 2 and Figure 4 As shown, in order to reduce the amount of atomized paint sprayed from the nozzle 401 in the air, a shielding cover 701 can be set on the connecting plate 311. The shielding cover 701 is trumpet-shaped, and its larger opening is rectangular. The paint outlet of the nozzle 401 passes through the smaller opening of the shielding cover 701 and faces the larger opening of the shielding cover 701. The movable spraying range of the nozzle 401 covers the larger opening of the shielding cover 701. A shielding plate 702 is fixedly provided on the nozzle 401, and the shielding plate 702 blocks the smaller opening from the outside of the shielding cover 701. In order to facilitate transportation, the shielding cover 701 can be detachably fixedly connected to the connecting plate 311. In this embodiment, the shielding cover 701 is plugged into the connecting plate 311 by a plug rod fixed thereto.

[0051] like Figure 6As shown, the running mechanism 600 is arranged below the base plate 110 and includes a front and rear running assembly 610, a left and right running assembly 620, a universal running assembly, and a switching assembly. The front and rear running assembly 610 includes a wheel frame 1 611 and front and rear running wheels 612 rotatably connected to the wheel frame 1 611. The rotation axes of the front and rear running wheels 612 are horizontal and perpendicular to the sliding direction of the vibration frame 320. The left and right running assembly 620 includes a wheel frame 2 621 and left and right running wheels 622 rotatably connected to the wheel frame 2 621. The rotation axes of the left and right running wheels 622 are horizontal and parallel to the sliding direction of the vibration frame 320. The wheel frames 1 611 and 2 621 are arranged below the frame 100 and are respectively connected to the frame 100 in a vertical sliding direction. The universal running assembly includes a plurality of universal wheels 630 arranged at the bottom of the frame 100. The switching assembly includes a bidirectional screw 642 that is vertically connected to the bottom of the frame 100, and the wheel frame 1 611 and the wheel frame 2 621 are respectively threadedly connected to the two opposite sections of the thread of the bidirectional screw 642. Figure 7 、 Figure 8 and Figure 9 As shown, when the lowest points of the front and rear wheels 612 and the left and right wheels 622 are at the same height, and the lowest points of the front and rear wheels 612 are higher than the lowest point of the universal wheel 630, there is a gap between the first wheel frame 611 and the second wheel frame 621. When the front and rear wheels 612 and the left and right wheels 622 are at their farthest distance from each other, the lower lowest point of the two wheels is lower than the lowest point of the universal wheel 630. The bidirectional screw 642 can be rotated manually or driven by a switching motor 643. In this embodiment, the latter is used.

[0052] Before use, the shielding cover 701 can be disassembled, the lifting platform 1 250 and the lifting platform 2 210 can be lowered to the lowest position, and the walking mechanism 600 can be switched to the universal wheel 630 for operation. When spraying paint on the wall facade, first start the lifting motor 2 240 to raise the nozzle 401 to a certain height and then temporarily fix it. Install the shielding cover 701, and reverse the lifting motor 240 to lower the nozzle 401. Using the lowest end of the shielding cover 701 as a reference, adjust the initial height of the nozzle 401, move the equipment to the side of the wall to be sprayed, with the nozzle 401 facing the wall. The walking mechanism 600 can be switched to the front and rear walking wheels 612 to adjust the distance to the wall. It is important to keep a certain distance between the shielding cover 701 and the wall. The walking mechanism 600 can be switched to the left and right walking wheels 622.
