Description

Technical Field

[0001] The present invention relates to the technical field of real stone paint spraying equipment, and in particular to a real stone paint spraying equipment for the exterior wall of a show flat used in architectural design. Background Art

[0002] With the continuous advancement of urban renewal projects, the requirements for exterior wall decoration in the field of architectural design are also increasing day by day. As a new type of exterior wall decoration material, real stone paint has been widely used in the exterior wall decoration of show flats and various buildings due to its natural color, good texture and excellent weather resistance. However, in the actual application process, especially in special scenarios such as narrow streets and high-altitude hanging baskets in urban renewal projects, traditional real stone paint spraying equipment faces many challenges.

[0003] Existing real stone paint spraying equipment usually consists of an air compressor, a material pumping pump and a spray gun. These devices simultaneously transport paint and high-pressure air to the spray gun through the material pumping pump and the air compressor for spraying. Although this design performs well when dealing with the exterior walls of show flats at general heights, it faces significant challenges when spraying at high altitudes or on complex structures (such as narrow streets, building corners, etc.). Especially when spraying tasks need to be carried out on high-rise buildings or complex structures, since long pipelines are required to connect the air compressor, the material pumping pump and the spray gun, this not only increases the operation difficulty, but also causes about 30% air pressure loss, resulting in poor stability of paint delivery. Moreover, the traditional equipment adopts a split design. The weight of the air compressor is usually between 80 and 150 kilograms, and the weight of the material pumping pump is also between 30 and 50 kilograms. The total moving weight usually exceeds 200 kilograms, resulting in a large overall weight, difficult transfer, and when working at high altitudes, the weight of the paint inside all pipelines needs to be supported by the worker's arms, which will increase the work intensity and physical consumption. Continuous feeding in a complex environment is also a major problem. When the paint in the traditional equipment runs out, the worker needs to return to the ground from high altitude by himself or notify another worker at high altitude to add paint. In this way, the paint cannot be added and supplemented in time, not only the work efficiency is low, but also any additional operation at high altitude will increase the safety risk. Summary of the Invention

[0004] In view of this, the present invention provides a real stone paint spraying equipment for the exterior wall of a show flat used in architectural design, which can overcome the disadvantages of existing real stone paint spraying equipment, such as great operation difficulty, large work intensity, poor stability of paint delivery, inconvenient transfer, and inability to add and supplement paint in time when spraying at high altitudes or on complex structures.

[0009] Further, an arc-shaped groove is opened at the lower end of the loading cylinder, and an arc-shaped protrusion matching the arc-shaped groove is provided on the blocking plate.

[0014] 2. By the combined use of a micro air compressor and a small material pumping pump, the present invention can replace traditional large air compressors and material pumping pumps. This design not only reduces the overall weight of the equipment, facilitating single-person operation, but also avoids the problem of air pressure loss caused by long pipelines. Specifically, the micro air compressor compresses air and stores it in the air storage tank, and then stably transports the compressed air to the spray gun through the air delivery pipe, ensuring that the paint is evenly and stably sprayed onto the outer wall surface of the sample house under high pressure, improving the efficiency and quality of the spraying operation.

[0015] 3. Through the combined action of the stirring rod, the driving motor and the gearbox, the present invention can fully stir the real stone paint in the charging cylinder before spraying, ensuring uniform distribution of the paint components, thereby improving the consistency of the spraying effect. At the same time, the design of the baffle and the fixing plate can effectively prevent the paint from overflowing during the movement process, increasing the construction safety. In addition, when the spray gun is not in use, it can be placed in the placement rack on the binding strap and fixed by the elastic clamping plate, which not only facilitates carrying but also reduces the risk of accidental dropping, enhancing the comfort and convenience during the operation process.

A sealing gasket is also arranged at the top of the feed inlet of the small material pumping pump 9, and the top of the feed inlet of the small material pumping pump 9 is in contact with and communicated with the bottom of the loading cylinder 8. Under the action of the sealing gasket, it can ensure that the paint will not leak. A material delivery pipe 10 is connected to the outlet of the small material pumping pump 9 and kept in communication, and the end of the material delivery pipe 10 far away from the small material pumping pump 9 is connected with the spray gun 7 and kept in communication. Shoulder straps 11 are symmetrically connected to the left and right sides of the rear side of the mounting plate 1, and a binding strap 12 is connected to the lower part of the rear side of the mounting plate 1. Workers can carry out mobile operations with the loading cylinder 8 on their backs through the action of the shoulder straps 11 and the binding strap 12, so as to facilitate spraying the outer wall at a higher position, and there is no need to use a longer pipeline to connect the air compressor and the material pumping pump, ensuring the stability of paint delivery. There is also no need to use a high-power air compressor and material pumping pump. The micro air compressor pump 3 and the small material pumping pump 9 can be used to replace the existing large air compressor and material pumping pump for spraying work, which is convenient for transferring the site. Three control switches 13 are installed at intervals on the binding strap 12. A sealing component for sealing the bottom of the loading cylinder 8 is arranged on the loading cylinder 8. A moving component for controlling the movement of the loading cylinder 8 is arranged on the mounting plate 1.

[0035] As Figures 3-6As shown in the figure, the sealing assembly includes a contact plate 14, an arc-shaped sliding frame 15, a sealing plate 16, an electric push rod 17, a sliding tube 1701 and a connecting spring 18. A contact plate 14 is connected to the small feeding pump 9. An arc-shaped sliding frame 15 is slidably connected to the lower part of the charging cylinder 8. The left end of the arc-shaped sliding frame 15 is connected to a sealing plate 16, and a rubber pad is provided on the sealing plate 16 for blocking the bottom of the charging cylinder 8. The sealing plate 16 is in contact and cooperation with the contact plate 14. An electric push rod 17 is installed at the lower part of the front side of the mounting plate 1. The outer wall of the feeding port of the small feeding pump 9 is slidably connected to a sliding tube 1701. A sealing layer is provided on the inner wall of the sliding tube 1701. The sliding tube 1701 slidably penetrates through the contact plate 14. The inner diameter of the sealing layer is adapted to the outer diameter of the lower end of the charging cylinder 8, and the inner wall of the sealing layer is in contact with the outer wall of the lower end of the charging cylinder 8, so as to ensure the sealing performance between the charging cylinder 8 and the small feeding pump 9. And the sliding tube 1701 is connected to the telescopic rod of the electric push rod 17. Connecting springs 18 are wound around the outer sides of the arc-shaped sliding frames 15, and the two ends of the connecting springs 18 are respectively connected to the charging cylinder 8 and the arc-shaped sliding frames 15.

[0036] As Figures 7-9 shown in the figure, the moving assembly includes a connecting frame 19, a reduction motor 20, a rotating plate 21, a servo motor 22, a rotating block 23, a swing arm 24, a rotating seat 25, a fixing ring 26 and a locking mechanism. A connecting frame 19 is connected to the lower part of the left side of the mounting plate 1. A reduction motor 20 is installed at the rear side of the bottom of the connecting frame 19. A rotating plate 21 is rotatably connected inside the connecting frame 19, and the lower end of the rotating shaft of the rotating plate 21 is connected to the output shaft of the reduction motor 20. A servo motor 22 is installed at the front side of the bottom of the rotating plate 21. A rotating block 23 is rotatably connected to the front side of the top of the rotating plate 21, and the lower end of the rotating shaft of the rotating block 23 is connected to the output shaft of the servo motor 22. The upper part of the rotating block 23 is rotatably connected to a swing arm 24. The upper end of the swing arm 24 is rotatably connected to a rotating seat 25. The right side of the rotating seat 25 is connected to a fixing ring 26, and the inner wall of the fixing ring 26 is fixedly connected to the outer wall of the charging cylinder 8. A locking mechanism for locking the swing arm 24 and the rotating seat 25 is arranged inside the swing arm 24; the locking mechanism includes a locking plate 29 and a return spring 30. Four first clamping grooves 27 and four second clamping grooves 28 are circumferentially spaced on both the rotating block 23 and the rotating seat 25. The first clamping grooves 27 and the second clamping grooves 28 correspond to each other one by one, and the first clamping grooves 27 and the second clamping grooves 28 are concentrically adjacent. The inner walls of the first clamping grooves 27 and the second clamping grooves 28 are both arc-shaped. Four locking plates 29 are circumferentially spaced and slidably connected to both the left and right sides inside the swing arm 24. The shape of the end of the locking plate 29 is adapted to the shape of the first clamping grooves 27 and the second clamping grooves 28, and the locking plate 29 can be stuck in the first clamping grooves 27 or the second clamping grooves 28. Two return springs 30 are connected between each locking plate 29 and the swing arm 24.

[0037] Initially, the loading cylinder 8 is filled with an appropriate amount of paint. The bottom of the loading cylinder 8 is aligned and communicated with the top of the feeding port of the small pumping pump 9. The sliding tube 1701 blocks the outside of the gap between the bottom of the loading cylinder 8 and the feeding port of the small pumping pump 9, so as to prevent the paint in the loading cylinder 8 from leaking. Moreover, the blocking plate 16 is in contact with the contact plate 14, and the connecting spring 18 is in a compressed state. The locking plate 29 is stuck in the first clamping groove 27. Workers can fix the mounting plate 1 to their backs through the shoulder strap 11 and the binding strap 12, so as to drive the loading cylinder 8 to move. When spraying the outer wall of the show flat is required, the worker needs to press the left control switch 13 once to make the micro air compressor pump 3 start working. The micro air compressor pump 3 can compress air and transport the compressed air to the air storage tank 4 for storage. And the compressed air in the air storage tank 4 will flow into the air delivery pipe 6. Then press the right control switch 13 once to make the small pumping pump 9 start working. The small pumping pump 9 can extract the paint inside the loading cylinder 8 and transport the paint to the feeding pipe 10. Then the worker needs to hold the spray gun 7 and aim it at the position to be sprayed, and open the spray gun 7, so that the paint in the feeding pipe 10 can enter the spray gun 7. At the same time, the compressed air in the air delivery pipe 6 will enter the spray gun 7 and be ejected, so as to drive the paint to be ejected to the position to be sprayed and complete the spraying work. When the paint in the loading cylinder 8 is used up, press the left and right control switches 13 again to make the micro air compressor pump 3 and the small pumping pump 9 stop working. Then press the middle control switch 13 once to make the electric push rod 17, the reduction motor 20 and the servo motor 22 start working. The electric push rod 17 can drive the sliding tube 1701 to move downward and separate from the loading cylinder 8. Subsequently, the reduction motor 20 will drive the rotating plate 21 to rotate forward by 150 degrees, so as to drive the servo motor 22, the rotating block 23, the swing arm 24, the rotating seat 25, the fixing ring 26 and the loading cylinder 8 to rotate forward by 150 degrees with the rotation axis of the rotating plate 21 as the rotation center. The bottom of the loading cylinder 8 will gradually separate from the top of the feeding port of the small pumping pump 9, and the connecting spring 18 will gradually return to its original state. At this time, the arc-shaped sliding frame 15 and the blocking plate 16 remain stationary, while the bottom of the loading cylinder 8 will gradually move onto the blocking plate 16, so that the blocking plate 16 blocks the bottom of the loading cylinder 8. When the connecting spring 18 completely returns to its original state, the loading cylinder 8 will drive the arc-shaped sliding frame 15 and the blocking plate 16 to rotate forward synchronously, so that the blocking plate 16 separates from the contact plate 14. Subsequently, the servo motor 22 will drive the rotating block 23 to rotate horizontally by 180 degrees. The rotating block 23 can drive the swing arm 24, the rotating seat 25, the fixing ring 26 and the loading cylinder 8 to rotate horizontally by 180 degrees with the rotation axis of the rotating block 23 as the rotation center, so that the loading cylinder 8 moves to the front of the worker. Then the worker can hold the loading cylinder 8 and press down the swing arm 24 to keep the loading cylinder 8 in a vertical state, so that the swing arm 24 rotates downward to a horizontal state (such as Figure 6As shown in the figure, at this time, the swing arm 24 rotates relative to the rotating block 23 and the rotating seat 25. Under the elastic force of the return spring 30, the locking plate 29 can be disengaged from the first card slot 27, and the locking plate 29 can be snapped into the second card slot 28. In this way, the height of the charging cylinder 8 can be reduced, which is convenient for workers to replenish the paint inside the charging cylinder 8. When workers are working at height, they can place the barreled paint on the lifting platform so that workers can replenish the paint during the high-altitude operation. The weight of the charging cylinder 8 after being filled with paint is about ten catties. Through the action of sixteen return springs 30, the positions of the swing arm 24 and the charging cylinder 8 can be stabilized (when not affected by external forces), so as to prevent the swing arm 24 from swinging downward due to the weight of the charging cylinder 8. Then the worker can hold the charging cylinder 8 and rotate the swing arm 24 upward to reset, so that the locking plate 29 is disengaged from the second card slot 28, and the locking plate 29 can be snapped into the first card slot 27. Then press the middle control switch 13 once to make the reduction motor 20, the servo motor 22 and the electric push rod 17 work again. The servo motor 22 will drive the rotating block 23 to horizontally reverse 180 degrees. The rotating block 23 can drive the swing arm 24, the rotating seat 25, the fixed ring 26 and the charging cylinder 8 to horizontally reverse 180 degrees and reset with the rotation axis of the rotating block 23 as the rotation center. Subsequently, the reduction motor 20 will drive the rotating plate 21 to rotate backward 150 degrees to reset, so as to drive the servo motor 22, the rotating block 23, the swing arm 24, the rotating seat 25, the fixed ring 26 and the charging cylinder 8 to rotate backward 150 degrees with the rotation axis of the rotating plate 21 as the rotation center. The charging cylinder 8 will drive the arc-shaped sliding frame 15 and the sealing plate 16 to rotate backward synchronously. When the sealing plate 16 contacts the contact plate 14, the arc-shaped sliding frame 15 and the sealing plate 16 stop rotating, while the charging cylinder 8 will continue to rotate, so that the bottom of the charging cylinder 8 will gradually move away from the sealing plate 16, the connecting spring 18 is compressed, and the bottom of the charging cylinder 8 will gradually approach the top of the feed inlet of the small pumping pump 9 and align, so that the charging cylinder 8 moves back behind the worker. Subsequently, the electric push rod 17 can drive the sliding tube 1701 to move upward to block the gap outside between the bottom of the charging cylinder 8 and the feed inlet of the small pumping pump 9 again. In this way, when adding paint, it is not necessary for workers to untie the back strap 11 and the binding strap 12, then put the charging cylinder 8 on the ground to add paint, and then pick up the charging cylinder 8 again, which can reduce the operation steps and facilitate a single worker to operate.

[0038] As Figure 7 and Figure 10As shown in the figure, an arc-shaped groove 31 is formed on the lower left side of the charging cylinder 8, and an arc-shaped protrusion 32 that fits with the arc-shaped groove 31 is provided on the upper part of the sealing plate 16. When the sealing plate 16 blocks the bottom of the charging cylinder 8, the paint inside the charging cylinder 8 will exert pressure on the sealing plate 16. At the same time, the arc-shaped protrusion 32 can be stuck in the arc-shaped groove 31, so that the pressure received by the sealing plate 16 can be shared to the charging cylinder 8, preventing the arc-shaped sliding frame 15 from breaking due to excessive pressure; There is also a support frame 33. The middle part of the front side of the mounting plate 1 is connected with the support frame 33. The shape of the inner wall of the support frame 33 is adapted to the shape of the outer wall of the charging cylinder 8. When the bottom of the charging cylinder 8 is aligned with the top of the feed inlet of the small pumping device 9, the inner wall of the support frame 33 just contacts the outer wall of the charging cylinder 8, so as to support the charging cylinder 8 and maintain the stability of the charging cylinder 8.

[0039] As Figure 11 and Figure 12 shown in the figure, there are also a baffle 34, a fixing plate 35, a driving motor 36, a stirring rod 37 and a gearbox 38. The upper part of the front side of the mounting plate 1 is connected with the baffle 34. The front side of the top of the charging cylinder 8 is connected with the fixing plate 35. The shapes of the fixing plate 35 and the baffle 34 are both semi-circular. The driving motor 36 is installed on the front side of the top of the fixing plate 35. The stirring rod 37 is rotatably connected to the rear part of the fixing plate 35, and the stirring rod 37 is located inside the charging cylinder 8. The gearbox 38 is installed on the rear side of the top of the fixing plate 35, and the input end of the gearbox 38 is connected with the output shaft of the driving motor 36, and the output end of the gearbox 38 is connected with the stirring rod 37. When the bottom of the charging cylinder 8 is aligned with the top of the feed inlet of the small pumping device 9, the baffle 34 and the fixing plate 35 can contact each other to form a complete circle and block the top of the charging cylinder 8, so as to prevent the paint inside the charging cylinder 8 from spilling out. At the same time, starting the driving motor 36 can drive the stirring rod 37 to rotate through the gearbox 38, so as to stir the paint inside the charging cylinder 8 evenly and ensure the uniformity of the paint discharging and spraying.

[0040] As Figure 13 shown in the figure, there are also a placement rack 39 and an elastic clamping plate 40. The placement rack 39 is sleeved on the strap 12 so that the spray gun 7 can be placed in the placement rack 39 when not in use. The elastic clamping plate 40 is connected to the rear side of the placement rack 39, and the upper end of the elastic clamping plate 40 contacts the surface of the spray gun 7. The elastic force of the elastic clamping plate 40 can press the spray gun 7 to improve the stability of the spray gun 7 and prevent the spray gun 7 from falling easily.

[0041] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
