Description

Technical Field

[0001] This invention relates to the field of spraying equipment technology, specifically to an oil supply system for spraying. Background Technology

[0002] Currently, spraying equipment on the market can be divided into three types according to the degree of automation: manual spraying equipment, semi-automatic spraying equipment, and fully automatic spraying equipment.

[0003] Spraying equipment is divided into air spraying and airless spraying. High-pressure airless spraying, also known as airless spraying, refers to a spraying method that uses a high-pressure gear pump or plunger pump to directly pressurize the paint, forming a high-pressure paint that is sprayed out of the nozzle to form an atomized airflow that acts on the surface of the object (wall or wood surface).

[0004] In existing airless spraying technology, the oil inlet pipe is often directly inserted into the paint can for pressurized extraction. Since the oil pump and the paint can are separate units connected only by an oil pipe, the paint can also be moved when the oil pump needs to be moved. This makes the overall operation cumbersome and affects the overall work efficiency. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an oil supply system for spraying, so as to solve the technical problem that in the prior art, the oil supply pump and the paint can are separate units and are only connected by an oil pipe. When the oil supply pump needs to be moved, the paint can also need to be moved, which makes the overall operation more complicated and affects the overall work efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an oil supply system for spraying, comprising a main body and a top cover thereon, wherein a gear pump is installed inside the main body, and a first dual-shaft motor and a second dual-shaft motor are respectively installed on both sides inside the main body; A fixed partition is fixed at the bottom of the main body. A fixed suction tube that passes through the fixed partition is connected to the middle of the bottom of the gear pump. A telescopic suction tube is slidably connected to the outside of the fixed suction tube. A flared mouth is fixed at the bottom of the telescopic suction tube. A fixed base plate located at the top of the flared mouth is fixed at the bottom of the main body. First stirring blades are fixed on both sides of the outside of the flared mouth. Multiple sets of through holes are evenly opened inside the flared mouth. Multiple sets of protrusions that cooperate with the through holes are evenly fixed at the bottom of the fixed base plate. An output gear is rotatably connected to one side between the fixed partition and the fixed base plate. A gear ring that mates with the output gear is fixed to the outside of the telescopic suction tube. The output end of the second dual-shaft motor and the output gear are connected through a transmission mechanism. An oil outlet pipe that penetrates the top cover is provided at the middle position of the top of the gear pump and is connected to the external spray gun pipe. The transmission mechanism includes a first gear, a second gear, a first bevel gear, a second bevel gear, and a synchronous belt. The first gear is fixed to the outside of the output shaft on one side of the second dual-shaft motor and meshes with the second gear. The second gear and the first bevel gear are coaxial and mesh with each other. The shaft of the second bevel gear and the shaft of the output gear are connected by a synchronous belt. The inner output ends of the first and second dual-shaft motors and the two sets of oil supply gears are all connected by transmission gears, and the two sets of transmission gears are staggered.

[0007] By adopting the above technical solution, the invention is installed on a trolley, and the paint can is placed on the trolley with the paint can positioned directly below the main body. When spraying is required, the telescopic suction tube is manually extended into the paint can for suction. When the spraying needs to be moved, the invention and the paint can be moved as a whole by pulling the trolley without affecting the suction and spraying process. The overall operation is convenient and effectively improves the overall work efficiency. Furthermore, when the dual-shaft motor drives the gear pump to rotate and extract, the second dual-shaft motor drives the output gear to rotate through a series of transmission mechanisms. Since the telescopic suction tube is fully extended at this time, the gear ring on the outside of the telescopic suction tube meshes with the output gear. Under the rotation of the output gear, the gear ring, the telescopic suction tube, and the flared mouth rotate, thereby causing the flared mouth and the two sets of first stirring blades on both sides to rotate inside the paint can, thus further agitating the paint inside the paint can and preventing the paint from solidifying during use.

[0008] The present invention is further configured such that a first magnetic ring is fixed on the inner side of the fixed partition, and a second magnetic ring that is attracted to the first magnetic ring is fixed on the outer side of the telescopic suction tube.

[0009] By adopting the above technical solution, after the telescopic suction tube slides to the top, the second magnetic ring on the outside of the telescopic suction tube and the first magnetic ring inside the fixed partition attract each other, thereby fixing and supporting the telescopic suction tube.

[0010] The present invention is further configured such that a heat dissipation impeller located inside the main body is fixed at the outer output end of the first dual-axis motor, and multiple sets of heat dissipation holes communicating with the interior are evenly opened on both sides of the main body.

[0011] By adopting the above technical solution, the airflow generated by the rotation of the heat dissipation impeller can facilitate the exchange of gas heat between the inside of the main body and the outside world through the heat dissipation holes, thereby achieving the heat dissipation effect on the main body.

[0012] The present invention is further configured such that a fixing frame is fixed inside the main body, and the fixing frame has a mounting groove inside that cooperates with the gear pump, the first dual-shaft motor and the second dual-shaft motor. Both ends of the main body are fixed with mounting plates that cooperate with the external trolley, and the mounting plates have multiple sets of mounting holes inside.

[0013] By adopting the above technical solution, the fixing frame plays a supporting and fixing role, and the mounting plate can fix the entire invention to the external trolley.

[0014] The present invention is further configured such that multiple sets of second stirring blades are uniformly fixed at the bottom of the flared mouth, and each set of second stirring blades is fixed with a rubber pad at its end. The multiple sets of second stirring blades and multiple sets of through holes are arranged in staggered positions, and the number of second stirring blades is eight.

[0015] By adopting the above technical solution, the second stirring plate can rotate with the flared mouth, and the second stirring plate plays a role in stirring the paint inside the paint can, thereby further improving the stirring effect.

[0016] In summary, the present invention has the following beneficial effects: By mounting the entire invention on a trolley and placing the paint can on the trolley with the paint can positioned directly below the main body, when spraying is required, the telescopic suction tube can be manually extended into the paint can for suction. When moving the spraying device, simply pulling the trolley allows the entire invention and the paint can to be moved without affecting the suction and spraying process. The overall operation is convenient and effectively improves overall work efficiency. Furthermore, when the dual-shaft motor drives the gear pump to rotate and extract, the second dual-shaft motor drives the output gear to rotate through a series of transmission mechanisms. Since the telescopic suction tube is fully extended at this time, the gear ring on the outside of the telescopic suction tube meshes with the output gear. Under the rotation of the output gear, the gear ring, the telescopic suction tube, and the flared mouth rotate, causing the flared mouth and the two sets of first stirring blades on both sides to rotate inside the paint can, thereby further agitating the paint inside the paint can and preventing the paint from solidifying during use.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of the present invention will now be described. Example 1

[0021] An oil supply system for spraying, such as Figure 1-7 As shown, it includes a main body 1 and a top cover 2 on its top. A gear pump 3 is installed inside the main body 1, and a first dual-shaft motor 6 and a second dual-shaft motor 7 are installed on the two sides inside the main body 1, respectively. A fixed partition 15 is fixed at the bottom of the main body 1. A fixed suction tube 9 is connected to the middle of the bottom of the gear pump 3, which passes through the fixed partition 15. A telescopic suction tube 10 is slidably connected to the outside of the fixed suction tube 9. A flared mouth 11 is fixed at the bottom of the telescopic suction tube 10. A fixed base plate 16 is fixed at the top of the flared mouth 11 at the bottom of the main body 1. A first stirring plate 13 is fixed on both sides of the outside of the flared mouth 11. The first stirring plate 13 can stir the paint to a certain extent, which not only makes it easier to extract, but also avoids the problem of paint solidification. Multiple sets of through holes 12 are evenly opened inside the flared mouth 11. Multiple sets of protrusions 17 that cooperate with the through holes 12 are evenly fixed at the bottom of the fixed base plate 16. An output gear 22 is rotatably connected to one side between the fixed partition 15 and the fixed base plate 16. A gear ring 14 that mates with the output gear 22 is fixed to the outside of the telescopic suction tube 10. The output end of the second dual-shaft motor 7 is connected to the output gear 22 through a transmission mechanism. An oil outlet pipe 8 that penetrates the top cover 2 is provided at the middle position of the top of the gear pump 3, and the oil outlet pipe 8 is connected to the external spray gun pipe. By installing the entire invention on the trolley, placing the paint can on the trolley and positioning the paint can directly below the main body 1, when spraying is required, the telescopic suction tube 10 is manually extended into the paint can for suction. When it is necessary to move the spraying, the entire invention and the paint can be moved as a whole by pulling the trolley without affecting the overall suction and spraying process. The overall operation is convenient and effectively improves the overall work efficiency. Furthermore, when the dual-shaft motor drives the gear pump 3 to rotate and extract, the second dual-shaft motor 7 drives the output gear 22 to rotate through a series of transmission mechanisms. Since the telescopic suction tube 10 is fully extended at this time, the gear ring 14 on the outside of the telescopic suction tube 10 meshes with the output gear 22. Under the rotation of the output gear 22, the gear ring 14, the telescopic suction tube 10, and the flared mouth 11 are driven to rotate, thereby causing the flared mouth 11 and the two sets of first stirring blades 13 on both sides to rotate inside the paint can, thereby further agitating the paint inside the paint can and preventing the paint from solidifying during use. The transmission mechanism includes a first gear 18, a second gear 19, a first bevel gear 20, a second bevel gear 21, and a synchronous belt 23. The first gear 18 is fixed to the outside of the output shaft on one side of the second dual-shaft motor 7 and meshes with the second gear 19. The second gear 19 and the first bevel gear 20 are coaxially arranged, and the first bevel gear 20 and the second bevel gear 21 mesh with each other. The shaft of the second bevel gear 21 and the shaft of the output gear 22 are connected by the synchronous belt 23. The inner output ends of the first dual-shaft motor 6 and the second dual-shaft motor 7 are all connected to the two sets of oil supply gears 4 by the meshing transmission gears 5, and the two sets of transmission gears are staggered.

[0022] Please see Figure 3 A first magnetic ring 24 is fixed inside the fixed partition 15, and a second magnetic ring 25, which is opposite in polarity to the first magnetic ring 24, is fixed outside the telescopic suction tube 10. By setting the above structure, after the telescopic suction tube 10 slides to the top, the second magnetic ring 25 outside the telescopic suction tube 10 is attracted to the first magnetic ring 24 inside the fixed partition 15, thereby fixing and supporting the telescopic suction tube 10.

[0023] Please see Figure 1 and Figure 2The first dual-axis motor 6 has a heat dissipation impeller 27 fixed at its outer output end inside the main body 1. Multiple sets of heat dissipation holes 28 connected to the interior are evenly opened on both sides of the main body 1. By setting the above structure, the airflow generated by the rotation of the heat dissipation impeller 27 can exchange gas heat between the interior of the main body 1 and the outside under the action of the heat dissipation holes 28, thereby playing a role in heat dissipation of the main body 1.

[0024] Please see Figure 1 , Figure 4 and Figure 7 The main body 1 has a fixed frame 26 inside, and the fixed frame 26 has a mounting groove inside that cooperates with the gear pump 3, the first dual-shaft motor 6 and the second dual-shaft motor 7. Both ends of the main body 1 are fixed with mounting plates 29 that cooperate with the external trolley, and the mounting plates 29 have multiple sets of mounting holes inside. By setting the above structure, the fixed frame 26 plays a supporting and fixing role, and the mounting plates 29 can fix the entire invention to the external trolley. Example 2

[0025] Figure 8 This is a schematic diagram of the structure of the second embodiment of the present invention, wherein the first stirring plate 13 in the first embodiment is replaced by the second stirring plate 30. The second stirring plate 30 can rotate with the horn 11, wherein the second stirring plate 30 plays a role in stirring the paint inside the paint can, thereby further improving the stirring effect. Specifically, multiple sets of second stirring blades 30 are evenly fixed at the bottom of the horn mouth 11, and each of the second stirring blades 30 has a rubber pad fixed at its end. The rubber pad protects the bottom of the second stirring blade 30 and prevents the second stirring blade 30 from directly contacting the paint cylinder body. The multiple sets of second stirring blades 30 and multiple sets of through holes 12 are staggered, and there are eight sets of second stirring blades 30.

[0026] The working principle of this invention is as follows: When in use, the power is turned on, and the entire invention is fixedly connected to the external trolley through two sets of mounting plates 29. The trolley can then move the entire invention. The oil outlet pipe 8 of the gear pump 3 is connected to the external spray gun pipe. Under the pressure of the gear pump 3, the paint is sprayed onto the external object through the spray gun, thereby completing the spraying operation. By installing the entire invention on a trolley and placing the paint can on the trolley with the paint can directly below the main body 1, when spraying is required, the telescopic suction tube 10 is manually extended into the paint can for suction. When it is necessary to move the spraying device, the entire invention and the paint can can be moved as a whole by pulling the trolley without affecting the overall suction and spraying process. The overall operation is convenient and effectively improves the overall work efficiency. Furthermore, when the dual-shaft motor drives the gear pump 3 to rotate and extract, the second dual-shaft motor 7 drives the output gear 22 to rotate through a series of transmission mechanisms. Since the telescopic suction tube 10 is fully extended at this time, the gear ring 14 on the outside of the telescopic suction tube 10 meshes with the output gear 22. Under the rotation of the output gear 22, the gear ring 14, the telescopic suction tube 10, and the flared mouth 11 are driven to rotate, thereby causing the flared mouth 11 and the two sets of first stirring blades 13 on both sides to rotate inside the paint can, thereby further agitating the paint inside the paint can and preventing the paint from solidifying during use. Furthermore, when the telescopic suction tube 10 extends into the paint cylinder, the flared mouth 11 sinks to the bottom of the paint cylinder, and multiple sets of through holes 12 are evenly opened on the surface of the flared mouth 11. The paint can then pass through the multiple sets of through holes 12 and enter the inside of the flared mouth 11, thereby completing the paint extraction process under the action of the gear pump 3. Specifically, the gear pump 3 has two sets of meshing oil supply gears 4 inside. One end of one set of oil supply gears 4 meshes with the first dual-shaft motor 6 through a transmission gear 5, and the other end of the other set of oil supply gears 4 meshes with the second dual-shaft motor 7 through a transmission gear 5. The first dual-shaft motor 6 and the second dual-shaft motor 7 rotate synchronously in reverse, which can make the two sets of oil supply gears 4 mesh and rotate synchronously, greatly improving the oil supply and pressurization effect of the gear pump 3. After the spraying is completed, the paint can is removed from the trolley. At this time, the worker manually slides the telescopic suction tube 10 upward. After the telescopic suction tube 10 slides to the top, the second magnetic ring 25 on the outside of the telescopic suction tube 10 and the first magnetic ring 24 inside the fixed partition 15 attract each other, thus fixing and supporting the telescopic suction tube 10. The bottom of the fixed base plate 16 is uniformly fixed with protrusions 17 that penetrate multiple sets of through holes 12. When the top of the flared mouth 11 and the bottom of the fixed base plate 16 are completely attached, the multiple sets of protrusions 17 can extend into the interior of the through holes 12. The protrusions 17 can push out and clean the paint residue inside the through holes 12, effectively preventing the paint from solidifying inside the through holes 12, thus avoiding the problem of poor flowability of the next paint.

[0027] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the invention and are not intended to limit it. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the invention, but such modifications, substitutions, and variations are protected by patent law as long as they are within the scope of the claims of the present invention.
