Technical Field
[0001] This utility model relates to the field of spraying device technology, and in particular to a waterproof spraying device for building decoration. Background Technology
[0002] Building decoration is an engineering activity that improves the external or internal environment of a building using building materials such as stone and wood. It is mainly divided into three categories: public building decoration, residential decoration, and building curtain wall decoration. The decoration process includes spraying waterproof materials onto walls and floors, which requires the use of spraying machines and other equipment.
[0003] In existing technologies, traditional equipment has a limited capacity of paint buckets during large-scale construction, and frequent material changes lead to excessive downtime. In addition, the paint is wasted due to dripping during material changes. When spraying paint, the paint inside the bucket is not stirred evenly, is prone to sedimentation, and stratification occurs, resulting in cracking after the paint has cured. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a waterproof spraying device for building decoration, which has the advantages of quick bucket changing and uniform mixing, thus solving the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: a waterproof spraying device for building decoration, including a fixed plate, a bracket fixedly connected to the bottom of the fixed plate, the fixed plate including an outer ring plate and an inner ring plate, there is a gap between the outer ring plate and the inner ring plate, and both are fixedly supported by the bracket, a rotating plate is provided above the fixed plate, the rotating plate has a toothed groove A inside, a slide is provided between the outer ring plate, the inner ring plate and the rotating plate, the slide is provided with a circular and uniformly arranged ball bearing inside, a material bucket is symmetrically placed on the top of the rotating plate, the material bucket includes a preparation bucket and a mixing bucket, a motor A is fixedly sleeved inside the bracket, an electric push rod A is fixedly installed at the bottom of the inner ring plate away from the motor A, an electric push rod B is fixedly installed in the middle of the inner ring plate, and a bucket lid is fixedly installed at the end of the electric push rod B.
[0006] With the above structural design, the linkage between the rotating plate and motor A enables quick replacement of the material bucket. Furthermore, the cooperation between the electric push rod B and the bucket lid reduces downtime during material bucket replacement and minimizes paint dripping waste.
[0007] Preferably, the output shaft of the motor A is connected to a gear A via a coupling inside the tooth groove A, and the gear A meshes with the tooth groove A.
[0008] With the above structural setup, the output shaft of motor A drives gear A to rotate through the coupling. Since gear A meshes with tooth groove A, the rotation of gear A causes the rotating plate to rotate circumferentially above the fixed plate, thereby exchanging the positions of the material preparation tank and the mixing tank.
[0009] Preferably, the output shaft end of the electric push rod A is fixedly sleeved with a feeding channel, the top of the feeding channel is movably connected to the discharge port of the mixing tank, the feeding channel and the discharge port of the mixing tank are sealed after the mold is closed, and the other end of the feeding channel is connected to a spraying machine.
[0010] With the above structural setup, when changing the material bucket, first start the electric push rod A to make the feeding channel separate from the inside of the mixing bucket's outlet. After the positions of the preparation bucket and the mixing bucket have been changed, start the electric push rod A again. The output shaft of the electric push rod A will drive the feeding channel to move upward, so that the end of the feeding channel is connected to the outlet of the preparation bucket.
[0011] Preferably, a movable frame is fixedly installed at the output shaft end of the electric push rod B, and a motor B is fixedly installed above the end of the movable frame. The movable frame is fixedly connected to the bucket lid.
[0012] With the above structural setup, the electric push rod B drives the movable frame to move up or down through the movement of the output shaft. Since the barrel cover and the material barrel are sealed after the mold is closed, when the movable frame drives the barrel cover to move up, the mold closing between the barrel cover and the material barrel is broken.
[0013] Preferably, the barrel lid has a toothed groove B inside, and a gear B is rotatably mounted in the middle of the toothed groove B. The gear B is connected to the output shaft of the motor B through a coupling. A rotating shaft is fixedly connected to the bottom of the gear B. The rotating shaft is located above the discharge port of the mixing barrel. The bottom outer ring of the rotating shaft is evenly provided with blades. The blades are generally arc-shaped. The distance between the end of the blade and the inner wall of the mixing barrel is 5mm, and the distance between the bottom of the blade and the bottom wall of the mixing barrel is 10mm.
[0014] With the above structural design, when gear B drives the rotating shaft to rotate, the paddle blades drive the coating inside the mixing tank to rotate. Through the arc-shaped gathering of the mixing tank, the outer coating is evenly contracted inward, so that the coating can be quickly discharged through the discharge port of the mixing tank after being stirred and gathered.
[0015] Preferably, gear C is uniformly meshed with gear B and tooth groove B in a circular pattern. Gear C meshes with gear B and tooth groove B. A stirring scraper is fixedly connected below gear C. The stirring scraper has blades uniformly arranged in a circular pattern inside. The blades are 5mm away from the inner wall of the stirring tank.
[0016] With the above structural configuration, when gear B rotates, it drives gear C to rotate between gear B and tooth groove B through meshing with gear C. While gear C revolves around gear B as the center, it also rotates around itself as the center because it is meshed with both tooth groove B and gear B, and drives the stirring scraper to rotate to perform spiral stirring of the coating inside the mixing tank.
[0017] This utility model has the following advantages:
[0018] 1. This waterproof spraying device for building decoration achieves rotating bucket changing by setting up a fixed plate, a rotating plate, motor A, and a material bucket. After the paint in the mixing bucket is used up, electric push rods A and B are started simultaneously. Electric push rod A drives the material supply channel to move downward through its output shaft, while electric push rod B drives the movable frame to move upward through its output shaft. The movable frame drives motor B and the bucket cover to move vertically upward. Motor A is started, and the output shaft of motor A drives gear A to rotate through a coupling. Gear A meshes with tooth groove A, causing the rotating plate to rotate 180° above the fixed plate. After rotating, it stops working, switching the position of the material preparation bucket and the mixing bucket. Then, electric push rods A and B are started to connect the material supply channel with the outlet of the material preparation bucket. After the bucket cover and the material preparation bucket are closed, the spraying work can be restarted, achieving the effect of rotating to change the material bucket.
[0019] 2. This waterproof spraying device for building decoration achieves auxiliary dynamic material replenishment, reduces residue on the barrel wall, and uniform mixing through the setting of electric push rod, motor B, barrel lid, and other structures. When motor B is started, the output shaft of motor B drives gear B to rotate synchronously through a coupling. When gear B rotates, it drives the rotating shaft to rotate. When the rotating shaft rotates, it uses blades to horizontally stir the coating at the bottom of the mixing barrel and collects the coating evenly at the discharge port of the mixing barrel along the surface of the blades, so that the coating can enter the feeding channel from the discharge port of the mixing barrel. When gear B rotates, it drives gear C to rotate circumferentially between gear B and tooth groove B. When gear C rotates, it is driven by gear B and tooth groove B to revolve around gear B as the center, and gear C can also rotate on its own axis. Gear C uses a stirring scraper to perform circumferential and spiral stirring of the material inside the mixing barrel, and the blades of the stirring scraper can also stir the material on the inner wall of the mixing barrel, maximizing the utilization rate of the coating during use and achieving the effect of uniform mixing and reducing residue on the barrel wall.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-2 A waterproof spraying device for building decoration includes a fixed plate 1, with a bracket 2 fixedly connected to the bottom of the fixed plate 1. The bottom of the bracket 2 is evenly provided with universal wheels equipped with brakes to ensure the device is movable and stable during operation. The fixed plate 1 includes an outer ring plate 11 and an inner ring plate 12, with a gap between them, and both are fixedly supported by the bracket 2. A rotating plate 3 is provided above the fixed plate 1, with a toothed groove A31 inside the rotating plate 3. The outer ring plate 11, inner ring plate 12, and rotating plate 3 are connected to the bracket 2. Slides 13 are provided between the plates 3. Slides 13 are provided with evenly spaced ball bearings 14 in a circular shape inside, so that the rotating plate 3 can rotate evenly above the fixed plate 1. Material buckets 4 are symmetrically placed on the top of the rotating plate 3. Material buckets 4 include a preparation bucket 41 and a mixing bucket 42. A motor A5 is fixedly connected inside the bracket 2. An electric push rod A6 is fixedly installed at the bottom of the inner ring plate 12 away from the motor A5. An electric push rod B7 is fixedly installed in the middle of the inner ring plate 12. A bucket cover 8 is fixedly installed at the end of the electric push rod B7.
[0027] The discharge ports of the material preparation tank 41 and the mixing tank 42 are equipped with a connecting one-way valve. The valve will only be connected when either the material preparation tank 41 or the mixing tank 42 is connected to the material supply channel 61. When the connection between the material preparation tank 41 or the mixing tank 42 and the material supply channel 61 is disconnected, the coating will not flow out. This connecting valve is a mature existing technology and is not explained in detail in this application. It is just a conventional application of the prior art.
[0028] In practical applications, this device achieves quick replacement of the material bucket 4 by setting up the linkage between the rotating plate 3 and the motor A5. The electric push rod B7, in conjunction with the bucket lid 8, reduces downtime during material bucket 4 replacement and minimizes paint dripping waste. The output shaft of the motor A5 drives the gear A51 to rotate via a coupling. The gear A51, meshing with the tooth groove A31, drives the rotating plate 3 to rotate circumferentially above the fixed plate 1, switching the position of the material preparation bucket 41 to the mixing bucket 42. After preliminary mixing inside the material preparation bucket 41, it rotates to the position of the mixing bucket 42. Subsequently, the electric push rod B7, in conjunction with the bucket lid 8, covers the surface of the material preparation bucket 41. The electric push rod A6 connects the feeding channel 61 to the discharge port of the material preparation bucket 41, thus achieving the effect of replacing the material bucket 4.
[0029] Please see Figures 1-3 The output shaft of motor A5 is connected to gear A51 via a coupling inside tooth groove A31, and gear A51 meshes with tooth groove A31.
[0030] When the motor A5 is working, its output shaft drives the gear A51 to rotate through the coupling. Since the gear A51 meshes with the tooth groove A31 and the sliding balls 14 are evenly arranged between the fixed plate 1 and the rotating plate 3, the rotation of the gear A51 causes the rotating plate 3 to rotate in a circle above the fixed plate 1, so that the positions of the material preparation tank 41 and the mixing tank 42 are interchanged, thus achieving the effect of quickly changing the material tank 4.
[0031] Please see Figures 1-3 The output shaft end of the electric push rod A6 is fixedly sleeved with a feeding channel 61. The top of the feeding channel 61 is movably connected to the discharge port of the mixing tank 42. After the feeding channel 61 and the discharge port of the mixing tank 42 are closed, they are in a sealed state. The other end of the feeding channel 61 is connected to a spraying machine.
[0032] During the spraying operation, the end of the feeding channel 61 is connected to the outlet of the mixing tank 42 and they are sealed to each other, so that the paint inside the mixing tank 42 is transported to the spraying machine through the feeding channel 61. When changing the material tank 4, the electric push rod A6 is started first to disengage the feeding channel 61 from the outlet of the mixing tank 42. After the positions of the material tank 41 and the mixing tank 42 have been changed, the electric push rod A6 is started again. The output shaft of the electric push rod A6 drives the feeding channel 61 to move upward, so that the end of the feeding channel 61 is connected to the outlet of the material tank 41, reducing downtime.
[0033] Please see Figures 1-3 A movable frame 71 is fixedly installed at the end of the output shaft of the electric push rod B7, and a motor B72 is fixedly installed above the end of the movable frame 71. The movable frame 71 is fixedly connected to the barrel cover 8.
[0034] The electric push rod B7 drives the movable frame 71 to move up or down through the movement of the output shaft. Since the barrel cover 8 and the material barrel 4 are sealed after the mold is closed, when the movable frame 71 moves the barrel cover 8 to the upper position, the mold closing between the barrel cover 8 and the material barrel 4 is broken. After the positions of the preparation barrel 41 and the mixing barrel 42 are interchanged, the position of the movable frame 71 is controlled so that the barrel cover 8 can be inserted back into the preparation barrel 41 to stir and mix the material inside the preparation barrel 41. During the paint spraying, the paint on the inner wall of the preparation barrel 41 can be scraped clean to avoid paint waste.
[0035] Please see Figures 1-4 The barrel cover 8 has a toothed groove B81 inside. A gear B82 is rotatably mounted in the middle of the toothed groove B81. The gear B82 is connected to the output shaft of the motor B72 through a coupling. A rotating shaft 83 is fixedly connected to the bottom of the gear B82. The rotating shaft 83 is located above the discharge port of the mixing barrel 42. The bottom outer ring of the rotating shaft 83 is evenly provided with blades 84. The blades 84 are arc-shaped. The distance between the end of the blades 84 and the inner wall of the mixing barrel 42 is 5mm. The distance between the bottom of the blades 84 and the bottom wall of the mixing barrel 42 is 10mm. When the gear B82 drives the rotating shaft 83 to rotate, the blades 84 drive the coating inside the mixing barrel 42 to rotate. Through the arc-shaped gathering of the mixing barrel 42, the outer ring of coating is evenly contracted inward. The coating is gathered by the mixing of the mixing barrel 42 and can be quickly discharged through the discharge port of the mixing barrel 42.
[0036] Please see Figures 1-4 Gear C85 is evenly meshed with gear B82 and tooth groove B81 in a circular pattern. Gear C85 meshes with both gear B82 and tooth groove B81. The bottom of gear C85 is supported by gear B82 and tooth groove B81, allowing gear C85 to rotate only between gear B82 and tooth groove B81. A stirring scraper 86 is fixedly connected below gear C85. The stirring scraper 86 has evenly arranged blades in a circular pattern inside, with a distance of 5mm between the blades and the inner wall of the stirring tank 42. Gear B82... During rotation, the gear C85 is driven to rotate between gear B82 and tooth groove B81 through meshing with gear C85. While revolving around gear B82, gear C85 also rotates around itself because it is meshed with both tooth groove B81 and gear B82. This drives the stirring scraper 86 to rotate and perform spiral stirring of the coating inside the mixing tank 42. The blades can also rotate and scrape the coating near the inner wall of the mixing tank 42, so that the coatings are evenly mixed.
[0037] Working Principle: During operation, after the materials inside the mixing tank 42 are initially mixed, they are placed under the lid 8. Then, electric push rods A6 and B7 are activated. Electric push rod A6 controls the position of the feeding channel 61 via its output shaft, connecting the feeding channel 61 to the outlet of the mixing tank 42. This allows the paint inside the mixing tank 42 to be conveyed into the spraying machine through the feeding channel 61. When electric push rod B7 is working, its output shaft controls the movable frame 71 to move downwards. The movable frame 71 causes the lid 8 to close with the opening of the mixing tank 42. Then, motor B72 is activated. The output shaft of motor B72 drives gear B82 to rotate synchronously via a coupling. The rotation of gear B82 drives the rotating shaft 83 to rotate, and the rotation of the rotating shaft 83 drives the paddles 8... 4. The coating material at the bottom of the mixing tank 42 is horizontally stirred and evenly collected towards the discharge port of the mixing tank 42 along the surface of the blade 84. This facilitates the coating material entering the feeding channel 61 from the discharge port of the mixing tank 42. When the gear B82 rotates, it drives the gear C85 to rotate circumferentially between the gear B82 and the tooth groove B81. When the gear C85 rotates, it is driven by the meshing between the gear B82 and the tooth groove B81 to revolve around the gear B82 as the center. The gear C85 can also rotate on its own axis. The gear C85 stirs the material inside the mixing tank 42 in a circular and spiral motion through the stirring scraper 86. The blades of the stirring scraper 86 can also stir the material on the inner wall of the mixing tank 42, maximizing the utilization rate of the coating material during use.
[0038] After the coating inside the mixing tank 42 is used up, electric push rods A6 and B7 are started simultaneously. Electric push rod A6 drives the feeding channel 61 to move downward through its output shaft, disconnecting it from the discharge port of the mixing tank 42. Meanwhile, electric push rod B7 drives the movable frame 71 to move upward through its output shaft. The movable frame 71 drives motor B72 and the tank cover 8 to move vertically upward. When the blade 84 is disengaged from the opening of the mixing tank 42, motor A5 is started. The output shaft of motor A5 drives gear A51 to rotate through a coupling. Because A51 meshes with the toothed groove A31, it drives the rotating plate 3 to rotate circumferentially above the fixed plate 1. After rotating 180°, it stops working, switching the position of the preparation tank 41 and the mixing tank 42. Then, the electric push rods A6 and B7 are activated to connect the material supply channel 61 with the discharge port of the preparation tank 41. After the tank cover 8 and the preparation tank 41 are closed, the spraying work can be restarted. This achieves the effect of quickly changing the material tank 4, reducing downtime and reducing paint dripping waste.
