Description

Technical Field

[0001] This invention relates to the field of coating tool technology, specifically to an energy-saving and environmentally friendly coating equipment for building construction. Background Technology

[0002] Painting walls is an essential step in building construction. Currently, commonly used painting equipment mainly falls into the following categories:

[0003] Category 1: Traditional dip-type roller. This is currently the most common painting tool used on construction sites. The operator holds the roller handle, dips the roller into an open paint bucket to pick up paint, and then rolls it evenly on the wall or a special tray before applying the paint. This method is simple in structure and low in cost, but it has obvious shortcomings: the amount of paint dipped each time is greatly affected by the manual force, the viscosity of the paint, and the roller's absorbency, making it impossible to control the quantity precisely; the paint bucket is often left open, and the surface moisture or low-volatile components of the environmentally friendly paint continue to evaporate, easily causing skinning and dust accumulation, resulting in waste.

[0004] The second type is the pump-feed type paint sprayer. This type of equipment uses an electric or pneumatic pump to deliver paint from a storage tank through a hose to the roller or brush head. Its disadvantages are: it requires electricity or compressed air to operate, resulting in high energy consumption; a power or air supply is also needed at the construction site; the pipelines are long and have many valves, leaving a large amount of paint residue in the pipelines and brush head after construction, which is wasteful and difficult to clean, requiring a large amount of water and organic solvents for cleaning, causing secondary pollution.

[0005] Category 3: Spraying equipment. Although spraying equipment provides continuous material supply, the paint atomization and dispersion are severe, resulting in a large amount of overspray and drift. The paint utilization rate is low, and the atomized particles pollute the air and endanger the health of construction workers. It has high requirements for the construction site environment and is not suitable for small-area, corner, and indoor fine painting operations.

[0006] Therefore, there is a need to provide an energy-saving and environmentally friendly coating application equipment for building construction, which aims to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide an energy-saving and environmentally friendly building construction coating application device, which aims to solve the problems mentioned in the background art.

One end of the second movable rod is slidably connected to the limiting groove. The air pump is connected to the second side plate through a fixed rod. A piston is slidably connected to the inner wall of the air pump. The piston is connected to the second movable rod through an L-shaped rod. An air outlet is connected to the bottom of the air pump, and an air inlet is provided at the bottom of the air pump. One-way valves are installed at both the air outlet and the air inlet. The air inlet only allows air to enter but not exit, and the air outlet only allows air to exit but not enter.

[0013] As a further embodiment of the present invention, a sealing plate is installed in the air intake pipe, and a sealing sleeve is coaxially connected to the outer side of the air outlet pipe.

[0016] In summary, the beneficial effects of this invention are:

[0017] The system utilizes the rolling friction generated between the roller brush sleeve and the wall surface during operation as a power source to drive the air pumping mechanism, achieving a metered output of paint. The entire process requires no motor, air pump, or power supply, making it more energy-efficient and particularly suitable for construction sites without power or noise-sensitive indoor environments.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 6This invention provides an energy-saving and environmentally friendly building construction coating application device, comprising a roller brush sleeve 1, a bending rod 4, and a handle 5, for coating application via the roller brush sleeve 1. A fixed sleeve 11 is coaxially arranged inside the roller brush sleeve 1, and the roller brush sleeve 1 is fitted onto the outside of the fixed sleeve 11. Several discharge holes 12 are provided on the coating side of the fixed sleeve 11, which discharge coating material into the roller brush sleeve 1. The coating side refers to the side closest to the wall during operation. A first side plate 2 is detachably connected to one side of the fixed sleeve 11, and the first side plate 2 is connected to the handle 5 via the bending rod 4. A second side plate 6 is fixedly connected to the other side of the fixed sleeve 11. A circular hole is provided at the center of the second side plate 6, and a rotating column 7 is rotatably connected to the circular hole, specifically through a bearing. The rotating column 7 is connected to the roller brush sleeve 1 via a connecting assembly, meaning that the roller brush sleeve 1 can rotate with the rotating column 7. The fixed sleeve 11 houses a storage tank 13, which is connected to an air inlet pipe 30 and a discharge pipe 22. Several discharge arc plates 18 are connected to the inner wall of the fixed sleeve 11. The interior of each discharge arc plate 18 communicates with a discharge hole 12. The discharge pipe 22 is connected to the interior of the discharge arc plates 18 via a diversion pipe. During use, the paint in the storage tank 13 enters the discharge arc plates 18 through the diversion pipe, and then enters the roller brush sleeve 1 through the discharge hole 12. An air pumping mechanism is installed on the inner side of the second side plate 6, connected to the air inlet pipe 30. The air pumping mechanism is driven by the rotating column 7. A pressure valve is installed on the discharge pipe 22; the valve opens only when the pressure exceeds a set value. During use, the roller brush sleeve 1 rotates with the rotating column 7, continuously pumping air into the storage tank 13, causing the pressure valve to open and allowing the paint to flow out.

[0032] In this embodiment of the invention, a plurality of brush rods 9 are connected to the inner side of the brush sleeve 1. The brush rods 9 are arranged in a circumferential array. Each brush rod 9 has a brush ring 10 connected to both ends. The brush ring 10 is fitted onto the outer side of the fixed sleeve 11. The connecting assembly consists of a plurality of connecting sleeves 8 arranged in a circumferential array. The connecting sleeves 8 are L-shaped. One end of each connecting sleeve 8 is fixedly connected to the rotating column 7, and the other end is used to insert a brush rod 9. Some brush rods 9 pass through the brush ring 10 and are then inserted into the connecting sleeve 8.

[0033] In this embodiment of the invention, a plurality of threaded holes 17 are provided on the outer end face of the fixing sleeve 11. The first side plate 2 is mounted on the fixing sleeve 11 by bolts 3, and the threaded holes 17 cooperate with the bolts 3, thus facilitating the disassembly of the first side plate 2. It also facilitates the disassembly of the roller brush sleeve 1. During disassembly, the first side plate 2 is removed first, and then the roller brush sleeve 1, together with the roller brush rod 9 and the roller brush ring 10, is removed.

[0034] In this embodiment of the invention, the inner wall of the fixing sleeve 11 is provided with a plurality of guide grooves 15, and the outer side of the storage tank 13 is connected with a plurality of guide plates 16. The guide plates 16 are slidably connected to the guide grooves 15. The storage tank 13 is provided with a bottle mouth, and a bottle cap 14 is installed at the bottle mouth. By providing the guide plates 16 and guide grooves 15, it is convenient to install and remove the storage tank 13. The paint is poured into the storage tank 13 through the bottle mouth.

[0035] In this embodiment of the invention, the air pumping mechanism includes a first movable rod 26, a second movable rod 27, and an air pump 23. One end of the first movable rod 26 is rotatably connected to the edge of the inner side of the rotating column 7, and the other end of the first movable rod 26 is rotatably connected to the second movable rod 27. A limiting plate 21 is connected to the inner side of the second side plate 6, and the two limiting plates 21 form a limiting groove. One end of the second movable rod 27 is slidably connected to the limiting groove. Thus, when the rotating column 7 rotates, the second movable rod 27 will perform reciprocating linear motion. The air pump 23 is connected to the second side plate 6 via a fixing rod 29. A piston is slidably connected to the inner wall of the air pump 23. The piston is connected to the second movable rod 27 via an L-shaped rod 28. An air outlet pipe 24 is connected to the bottom of the air pump 23, and an air inlet 25 is provided at the bottom of the air pump 23. Both the air outlet pipe 24 and the air inlet 25 are equipped with one-way valves. The air inlet 25 only allows air to enter but not exit, and the air outlet pipe 24 only exits air but does not enter. In this way, the second movable rod 27 will move the piston in a reciprocating linear motion, thereby realizing the air pumping operation.

[0036] Please see Figures 1 to 7 In this embodiment of the invention, a sealing piece 33 is installed in the air intake pipe 30. The sealing piece 33 is a thin sheet that can be punctured. A sealing sleeve 31 is coaxially connected to the outer surface of the air outlet pipe 24. A first sealing ring 32 is installed on the sealing sleeve 31. A chamfer is provided at the inner port of the sealing sleeve 31. The inner diameter of the sealing sleeve 31 is the same as the outer diameter of the air intake pipe 30. The inner diameter of the air intake pipe 30 is the same as the outer diameter of the air outlet pipe 24. The air intake pipe 30 and the air outlet pipe 24 are inserted to complete the installation. After installation, the end face of the air intake pipe 30 contacts the first sealing ring 32, and the interface has good sealing performance. The air outlet pipe 24 will puncture the sealing piece 33.

[0037] Please see Figures 1 to 8In this embodiment of the invention, the diversion pipe includes a diversion sub-pipe 19 and a diversion main pipe 20. Each diversion sub-pipe 19 is connected to a discharge arc plate 18. A feed pipe 34 is connected to the diversion main pipe 20, and the feed pipe 34 is connected to the discharge pipe 22 via a telescopic pipe 35. The port of the outer side of the telescopic pipe 35 is inclined, and a second sealing ring 36 is installed on the inner wall of the feed pipe 34. After installation, the telescopic pipe 35 will be in close contact with the second sealing ring 36 to ensure sealing. The inner wall of the discharge pipe 22 is connected to a flanged pipe 37. The flanged portion of the flanged pipe 37 is fixedly connected to the discharge pipe 22. The outer surface of the flanged pipe 37 is slidably connected to the inner wall of the telescopic pipe 35. The outer surface of the telescopic pipe 35 is also slidably connected to the inner wall of the discharge pipe 22. The end face of the telescopic pipe 35 is connected to the flanged portion of the flanged pipe 37 via a return spring 38. The outer diameter of the telescopic pipe 35 is the same as the inner diameter of the feed pipe 34. When the storage tank 13 is installed, as the storage tank 13 slides in, the inclined surface on the telescopic pipe 35 will contact the feed pipe 34, and the telescopic pipe 35 will be squeezed and contracted until the telescopic pipe 35 and the feed pipe 34 are completely aligned. Under the action of the return spring 38, the telescopic pipe 35 pops out, completing the docking installation.

[0038] The working process of this embodiment of the invention is as follows: First, paint is poured into the storage tank 13. Then, the storage tank 13 is installed inside the fixing sleeve 11, simply sliding it into the guide groove 15. After installation, the telescopic tube 35 and the feed tube 34 are successfully connected, and the air outlet tube 24 is inserted into the air inlet tube 30. Then, operation can begin. During operation, the roller brush sleeve 1 rotates with the rotating column 7, driving the air pumping mechanism to continuously pump air into the storage tank 13, causing the pressure valve to open, thereby allowing the paint in the storage tank 13 to flow into the roller brush sleeve 1.
