Description

Technical Field

[0001] The present invention relates to the technical field of powder coating spraying, in particular to a powder coating mixing spraying device for interior decoration and a spraying method thereof. Background Art

[0002] A powder coating spraying system is a device used to apply powder coating to various surfaces. This equipment typically consists of a spray gun and a delivery system. It adheres the powder coating to the surface, where it solidifies after drying, forming a durable coating. Powder coating can also be used for interior decoration applications.

[0015] The present invention also provides a powder coating mixing and spraying method for interior decoration, which is applied to a powder coating mixing and spraying device for interior decoration. The powder coating mixing and spraying method for interior decoration comprises the following steps:

[0016] Step S1: The fluid powder coating and stabilizer are connected to the interior of two reciprocating chambers through the feed pipes, and the transport assembly can be driven to reciprocate by the drive assembly to intermittently transport the materials inside the reciprocating chambers. During the transport, the discharge assembly cooperates with the fluid powder coating and stabilizer to be transported from the discharge channel to the flat mouth respectively. High-pressure gas is sprayed through the high-pressure nozzle inside the flat mouth to refine and spray the materials transported by the discharge channel, so that the fluid powder coating and stabilizer can be blown out together and sprayed onto the outer surface of the object;

[0017] Step S2: When the driving component is working, the elliptical wheel is driven to rotate by starting the motor, which can then drive the two material transport components to reciprocate synchronously. In actual use, the motor can be a servo motor, which is convenient for people to control its rotation angle. The angle of each reciprocating rotation is 90 degrees;

[0018] Step S3: When the discharge assembly is working, the transport assembly is in a non-working state. At this time, the balls are located on both sides of the elliptical wheel. The material stored on one side of the sealing block inside the temporary storage chamber enters the annular chamber through the discharge hole and the bridge hole, and then enters the discharge channel inside the annular chamber through the discharge port and the bent flow channel, and finally flows into the flat mouth.

[0019] Step S4: When the material transport component is working, the discharge component is in a closed state. When the material transport component is working, the ball bearings are located at both ends of the elliptical wheel, and the discharge hole and the bridge hole are offset relative to each other, so the discharge component is cut off and cannot be conducted. Since the material transport rod slides toward the inside of the reciprocating cavity, the grid opening slides out from the inside of the limit ring and is connected with the reciprocating cavity, and the reflux hole and the guide hole are connected with each other. At this time, the material inside the reciprocating cavity can enter the interior of the temporary storage cavity through the grid opening.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention connects the fluid powder coating and stabilizer to the inside of two reciprocating chambers through a feed pipe, and the material transport component can be driven to reciprocate by a drive component to intermittently transport the material inside the reciprocating chamber. During the transport, the discharge component cooperates to transport the fluid powder coating and stabilizer from the discharge channel to the flat mouth respectively. High-pressure gas is sprayed through a high-pressure nozzle inside the flat mouth to refine and spray the material transported by the discharge channel, so that the fluid powder coating and stabilizer can be blown out together and sprayed onto the outer surface of the object, thereby achieving the purpose of simultaneously transporting the powder coating and stabilizer. In this way, it is possible to avoid the need to configure the raw materials in equal proportions before each spraying, and it is convenient for people to operate and construct;

[0022] 2. In the present invention, when the driving assembly is working, the elliptical wheel is driven to rotate by starting the motor, thereby driving the two material transport assemblies to reciprocate synchronously. In actual use, the motor can be a servo motor, which is convenient for people to control its rotation angle. The angle of each reciprocating rotation is 90 degrees. When the material transport assembly is driven to work, the balls on the material transport assembly will be synchronously located on both sides and ends of the elliptical wheel, thereby achieving the purpose of synchronous operation of the two material transport assemblies.

[0023] 3. In the present invention, when the discharge assembly is working, the transport assembly is in a non-working state. At this time, the ball bearings are located on both sides of the elliptical wheel. The material stored on one side of the sealing block inside the temporary storage chamber enters the annular chamber through the discharge hole and the bridge hole, then enters the discharge channel inside the annular chamber through the discharge port and the bent flow channel, and finally flows into the flat mouth. At the same time, external air enters the buffer chamber through the air inlet and the drainage port, enters the bent hole through the hollow tube inside the buffer chamber, and flows into the sealing block area inside the temporary storage chamber, thereby preventing the generation of a dead volume inside the temporary storage chamber.

[0024] 4. In the present invention, the discharge assembly is in a closed state when the material transport assembly is working. When the material transport assembly is working, the ball bearings are located at both ends of the elliptical wheel, and the discharge hole and the bridging hole are offset and relative to each other, so the discharge assembly is cut off and cannot be conducted. Since the material transport rod slides toward the inner side of the reciprocating cavity, the grid opening slides out from the inner side of the limit ring and is connected with the reciprocating cavity, and the return hole and the guide hole are connected with each other. At this time, the material inside the reciprocating cavity can enter the interior of the temporary storage cavity through the grid opening. When the material is injected into the temporary storage cavity, the air inside the temporary storage cavity will be discharged outward from the guide hole at the edge of one side, thereby ensuring that the injected material can fill the interior of the temporary storage cavity.

At the same time, the discharge component is cooperated to convey the fluid powder coating and stabilizer from the discharge channel 13 to the flat mouth 8 respectively, and high-pressure gas is sprayed through the high-pressure nozzle 7 inside the flat mouth 8 to refine and spray the material conveyed by the discharge channel 13, so that the fluid powder coating and stabilizer can be blown out together and sprayed onto the outer surface of the object.

[0037] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the material transport assembly includes a material transport rod 20, a temporary storage chamber 28 is opened inside the material transport rod 20, an inner chamber 29 is opened near the edge of one end of the material transport rod 20, and a discharge assembly is arranged inside the inner chamber 29. The top of the material transport rod 20 and the temporary storage chamber 28 are connected, and a guide ring 21 is fixed to the outer surface of the material transport rod 20. The guide ring 21 is slidably connected between the inner wall of the reciprocating chamber 14, and one side of the guide ring 21 is in contact with one side of the limit ring 15. One end of the material transport rod 20 slides through the inside of the mounting groove 9, and a ball 30 is rotatably provided at one end of the material transport rod 20. One end of the baffle rod 18 slides from the connection between the top of the material transport rod 20 and the temporary storage chamber 28 to the inside of the temporary storage chamber 28. A plurality of grid openings 22 are equidistantly opened on the inner walls of both sides of the temporary storage chamber 28 near the edge of one side, and a sealing ring 23 is fixed between the inner walls of the temporary storage chamber 28. A sealing block 26 is provided inside the temporary storage chamber 28, and one side of the sealing block 26 is sealed and fitted with one side of the sealing ring 23. A gap is left between the outer surface of the sealing block 26 and the inner wall of the temporary storage chamber 28. A hollow tube 27 is fixed to the bottom of the sealing block 26, and the bottom of the hollow tube 27 slides through the inner cavity 29. Two bending holes 31 are provided at the bottom of the sealing block 26, and one end of the two bending holes 31 corresponds to passing through the interior of the hollow tube 27. Guide holes 24 are provided on the inner walls of both sides of the temporary storage chamber 28 near the edge of the other end.

One end of the baffle rod 18 is fitted with one side of the sealing block 26, and a first spring 25 is fixed between the outer surface of one side of the guide ring 21 and the inner bottom surface of the annular bottom groove 17.

[0038] The effect achieved is that when the material transport component is working, the discharge component is in a closed state. When the material transport component is working, the rotation of the elliptical wheel 11 will drive the material transport rod 20 to push the inner side of the reciprocating cavity 14, and the balls 30 are located at both ends of the elliptical wheel 11. At this time, one side of the guide ring 21 and one side of the limit ring 15 are in contact with each other, and one end of the blocking rod 18 pushes the sealing block 26 to the side of the temporary storage cavity 28. The sealing ring 23 and the sealing block 26 are in an open state. When the sealing block 26 slides, it will drive the movable block 32 to slide downward. At this time, the discharge hole 35 and the bridge hole 36 are in contact with each other. The dislocation is relative, so the discharge assembly is cut off and cannot be conducted. Since the material transport rod 20 slides toward the inside of the reciprocating cavity 14, the grid opening 22 slides out from the inside of the limit ring 15 and communicates with the reciprocating cavity 14, and the return hole 19 and the guide hole 24 are communicated with each other. At this time, the material inside the reciprocating cavity 14 can enter the interior of the temporary storage cavity 28 through the grid opening 22. When the material is injected into the temporary storage cavity 28, the air inside the temporary storage cavity 28 will be discharged outward from the guide hole 24 at one edge, thereby ensuring that the injected material can fill the interior of the temporary storage cavity 28.

[0039] like Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 7As shown, the discharge assembly includes a movable block 32, which is slidably arranged between the inner wall of the inner cavity 29. A second spring 33 is fixed between one side of the movable block 32 and the inner wall of the inner cavity 29. A buffer cavity 40 is opened near the bottom edge of the movable block 32. One end of the hollow tube 27 is fixed to the movable block 32 and is connected to the buffer cavity 40. Two through holes 43 are opened on the inner wall of one side of the temporary storage cavity 28 to penetrate into the inner cavity 29. The inner walls of the two through holes 43 are equidistantly opened with a plurality of through holes 43 that penetrate into the temporary storage cavity 28. The discharge hole 35 of the top portion is provided with a guide rod 34 slidingly arranged between the inner walls of the two through holes 43. One end of the two guide rods 34 is fixed to the top of the movable block 32. An annular cavity 37 is provided inside the movable block 32 near the top edge. The outer surface of the guide rod 34 is provided with a plurality of bridging holes 36 that penetrate into the annular cavity 37 at equal intervals. The plurality of bridging holes 36 are correspondingly connected to the discharge hole 35. A discharge port 38 that penetrates the outer surface of the movable block 32 is provided on the inner wall of one side of the annular cavity 37. The outer surface of the transport rod 20 is provided with a A curved flow channel 39 is provided to penetrate into the inner cavity 29, and one end of the curved flow channel 39 is communicated with the discharge port 38. An air inlet 41 is provided on the inner wall of one side of the buffer cavity 40 and penetrates into the outer surface of the movable block 32. A drainage port 42 is provided on the outer surface of the material transport rod 20 and penetrates into the inner cavity 29. The air inlet 41 and the drainage port 42 are communicated with each other. An air inlet 16 is provided inside the conical guide block 1. One end of the air inlet 16 penetrates into the outer surface of the conical guide block 1, and the other end of the air inlet 16 extends to fit with the outer surface of the material transport rod 20. , and the other end of the air inlet 16 is communicated with the guide port 42. Two discharge channels 13 are provided inside the conical guide block 1. A side port 6 is provided on the outer surface of the conical guide block 1 near the bottom edge. A flat port 8 is provided on one side of the side port 6. A high-pressure nozzle 7 is fixed on the outer surface of the conical guide block 1 near one side edge. The high-pressure nozzle 7 is communicated with the flat port 8. One end of the two discharge channels 13 is correspondingly connected to the inside of the flat port 8, and the other end of the two discharge channels 13 is correspondingly extended to fit the outer surface of the material transport rod 20.

[0040] The effect achieved is that when the discharge assembly is working, the transport assembly is in a non-working state. At this time, the balls 30 are located on both sides of the elliptical wheel 11, and there is a gap between one side of the guide ring 21 and one side of the limit ring 15. The sealing block 26 and the sealing ring 23 are in a sealed state. At this time, the grid opening 22 on the transport rod 20 is on the inner side of the limit ring 15, and the grid opening 22 is not connected to the reciprocating cavity 14. One end of the guide hole 24 is offset relative to the return hole 19, and one end of the return hole 19 is located at the connection between the top of the transport rod 20 and the temporary storage cavity 28, which is in a closed state. Therefore, the overall mechanism of the transport assembly is in a closed state at this time, and the movable block 32 in the discharge assembly is located at the top of the inner cavity 29, and the guide rod 34 extends to the inside of the temporary storage cavity 28. At this time, the discharge hole 35 and the bridge hole 36 are connected to each other, and the discharge port 38 is connected to one side of the bending flow channel 39. The ends are interconnected, and the other end of the bending flow channel 39 is interconnected with the discharge channel 13, so that the material stored on one side of the sealing block 26 inside the temporary storage chamber 28 can enter the annular chamber 37 through the discharge hole 35 and the bridging hole 36, and then enter the discharge channel 13 through the discharge port 38 and the bending flow channel 39 inside the annular chamber 37, and finally flow into the flat mouth 8. At the same time, in order to prevent the interior of the temporary storage chamber 28 from being in a closed state and causing the material to be unable to be discharged outward, the air inlet 41 and the drainage port 42 are interconnected, and the drainage port 42 is interconnected with the air inlet 16, so that external air can enter the interior of the buffer chamber 40 through the air inlet 16 and the drainage port 42, and enter the bending hole 31 through the hollow tube 27 inside the buffer chamber 40 and flow into the sealing block 26 area inside the temporary storage chamber 28, thereby preventing the generation of a dead volume inside the temporary storage chamber 28.

[0041] like Figure 1 and Figure 3 As shown, the drive assembly includes a motor 10, which is located inside the mounting groove 9. A plurality of support rods 12 are fixed to the inner wall of the mounting groove 9, and one end of the plurality of support rods 12 is correspondingly fixed to the motor 10. An elliptical wheel 11 is fixed to the output end of the motor 10, and the outer surface of the ball 30 rolls in contact with the outer surface of the elliptical wheel 11.

[0042] The effect achieved is that when the driving component is working, the elliptical wheel 11 is driven to rotate by starting the motor 10, and then the two material transport components can be driven to reciprocate synchronously. In actual use, the motor 10 can adopt a servo motor, which is convenient for people to control its rotation angle. The angle of each reciprocating rotation is ninety degrees. When the material transport component is driven to work, the balls 30 on the material transport component will be synchronously located on both sides and ends of the elliptical wheel 11, thereby achieving the purpose of synchronous operation of the two material transport components.

[0043] For example, in one embodiment, the present invention further provides a method for mixing and spraying a powder coating for interior decoration, which is applied to the above-mentioned powder coating mixing and spraying device for interior decoration, comprising the following steps:

[0044] Step S1: The fluid powder coating and stabilizer are connected to the interior of the two reciprocating chambers 14 through the feed pipe 5, and the material transport component can be driven to reciprocate by the drive component to intermittently transport the material inside the reciprocating chamber 14. During the transport, the fluid powder coating and stabilizer are transported from the discharge channel 13 to the flat mouth 8 respectively in cooperation with the discharge component. High-pressure gas is sprayed inside the flat mouth 8 through the high-pressure nozzle 7 to refine and spray the material transported from the discharge channel 13, so that the fluid powder coating and stabilizer can be blown out together and sprayed onto the outer surface of the object;

[0045] Step S2: When the driving assembly is working, the elliptical wheel 11 is driven to rotate by starting the motor 10, thereby driving the two material transport assemblies to reciprocate synchronously. In actual use, the motor 10 can be a servo motor to facilitate people to control its rotation angle. The angle of each reciprocating rotation is 90 degrees;

[0046] Step S3: When the discharge assembly is in operation, the transport assembly is in a non-operating state. At this time, the balls 30 are located on both sides of the elliptical wheel 11. The material stored on one side of the sealing block 26 in the temporary storage chamber 28 enters the annular chamber 37 through the discharge hole 35 and the bridge hole 36. Then, the material enters the discharge channel 13 through the discharge port 38 and the curved flow channel 39 in the annular chamber 37, and finally flows into the flat port 8.

[0047] Step S4: When the material transport component is working, the discharge component is in a closed state. When the material transport component is working, the ball 30 is located at both ends of the elliptical wheel 11, and the discharge hole 35 and the bridge hole 36 are offset relative to each other, so the discharge component is cut off and cannot be conducted. Since the material transport rod 20 slides toward the inner side of the reciprocating cavity 14, the grid opening 22 slides out from the inner side of the limit ring 15 and communicates with the reciprocating cavity 14, and the reflux hole 19 and the guide hole 24 are communicated with each other. At this time, the material inside the reciprocating cavity 14 can enter the interior of the temporary storage cavity 28 through the grid opening 22.

[0048] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.

10. A powder coating mixing and spraying method for interior decoration, which is applied to a powder coating mixing and spraying device for interior decoration as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: Step S1: The fluid powder coating and stabilizer are connected to the inside of two reciprocating chambers (14) through the feed pipe (5), and the material transport component can be driven to reciprocate by the drive component, thereby intermittently transporting the material inside the reciprocating chamber (14). During the transport, the fluid powder coating and stabilizer are transported from the discharge channel (13) to the flat mouth (8) in cooperation with the discharge component. High-pressure gas is sprayed inside the flat mouth (8) through the high-pressure nozzle (7) to refine and spray the material transported by the discharge channel (13), so that the fluid powder coating and stabilizer can be blown out together and sprayed toward the outer surface of the object; Step S2: When the driving component is working, the elliptical wheel (11) is driven to rotate by starting the motor (10), thereby driving the two material transport components to reciprocate synchronously. In actual use, the motor (10) can be a servo motor to facilitate people to control its rotation angle. The angle of each reciprocating rotation is 90 degrees. Step S3: When the discharge assembly is working, the transport assembly is in a non-working state. At this time, the balls (30) are located on both sides of the elliptical wheel (11). The material stored on one side of the sealing block (26) inside the temporary storage chamber (28) enters the annular chamber (37) through the discharge hole (35) and the bridge hole (36), and then enters the discharge channel (13) through the discharge port (38) and the bending flow channel (39) inside the annular chamber (37), and finally flows into the flat mouth (8); Step S4: When the material transport component is working, the discharge component is in a closed state. When the material transport component is working, the ball (30) is located at both ends of the elliptical wheel (11), and the discharge hole (35) and the bridge hole (36) are offset relative to each other, so the discharge component is cut off and cannot be conducted. Since the material transport rod (20) slides toward the inside of the reciprocating cavity (14), the grid opening (22) slides out from the inside of the limit ring (15) and communicates with the reciprocating cavity (14), and the return hole (19) and the guide hole (24) are communicated with each other. At this time, the material inside the reciprocating cavity (14) can enter the interior of the temporary storage cavity (28) through the grid opening (22).
