Description

Technical Field

[0001] The present invention belongs to the technical field of paint proportioning and spraying: specifically, it relates to a paint proportioning and spraying device. Background Art

[0002] A paint proportioning and spraying device is a device specifically designed for paint proportioning and spraying. It usually integrates multiple functions such as paint storage, proportioning, mixing, and spraying. Its purpose is to improve the efficiency and accuracy of paint spraying. It can accurately measure and mix different types of paint raw materials according to preset proportioning requirements, and evenly spray the mixed paint onto the target object through the spraying device.

[0003] Some solutions have also been proposed in the prior art: for example, a Chinese patent with the publication number CN218902340U discloses a paint proportioning and spraying device, which relates to the technical field of paint proportioning and spraying. It includes a workbench. Through the mutual cooperation between a proportioning barrel, a measuring cylinder, a lead screw nut, an adjusting mechanism, a stirring shaft, and a transmission component, the measuring cylinder is used to measure a fixed amount of materials and add them to the proportioning barrel. When the adjusting mechanism drives the lead screw nut to move, the lead screw nut drives the stirring shaft to rotate through the transmission component to stir the materials in the proportioning barrel, completing the paint proportioning. When the paint spray gun moves for paint spraying, the stirring shaft rotates synchronously, which can effectively prevent problems such as uneven layering of the paint and ensure a good spraying effect of the paint.

[0004] After the paint is proportioned, it needs to be installed above the steel plate for spraying. Since the thickness of different batches of steel plates is different, the height of the existing device's nozzle cannot be adjusted accordingly for different batches of steel plate thicknesses during use, resulting in uneven paint thickness sprayed on steel plates of different thicknesses. Uneven coating thickness will cause appearance defects such as ripples on the surface of the steel plate, affecting the overall quality of the product.

Detailed implementation manners

[0032] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0033] Such as Figures 1 to 10As shown in the figure, the present invention provides a technical solution: a paint proportioning and spraying device, including a spraying table 1. A conveying main body 2 is arranged between two spraying tables 1. A steel plate 3 is arranged above the conveying main body 2. A proportioning barrel 4 is arranged directly above the spraying table 1. An outer ring sleeve 5 is fixedly connected to the outer wall of the proportioning barrel 4. A plurality of material barrels 6 are fixedly installed at the top of the outer ring sleeve 5. A paint spraying head 7 is fixedly communicated with the bottom of the proportioning barrel 4. An electric valve one 8 is fixedly installed outside the paint spraying head 7. Input pipes 21 are communicated between the plurality of material barrels 6 and the proportioning barrel 4. Electric valves two 22 are fixedly installed outside the input pipes 21. A feeding bin 23 is fixedly connected to the top of each material barrel 6. Stirring components for stirring and mixing raw materials and proportioning materials are arranged inside the plurality of material barrels 6 and the proportioning barrel 4. A self-adjusting component is arranged on one side below the proportioning barrel 4. The self-adjusting component is used to automatically adjust the heights of the proportioning barrel 4 and the paint spraying head 7 according to the thickness of the steel plate 3.

[0034] During operation: Before spraying, raw materials for proportioning paint are first added into each material barrel 6 through the feeding bin 23. Since the paint raw materials are all liquids, before the raw materials in the material barrel 6 are proportioned, the raw materials in each material barrel 6 are stirred by the stirring component, so that the concentration of the liquid raw materials is always kept uniform, avoiding stratification of the raw materials put into each material barrel 6 when they are stationary. Then, by opening each electric valve two 22, the liquid raw materials in each material barrel 6 enter the inside of the proportioning barrel 4 according to a proportion. After the raw materials enter, the stirring component can stir the raw materials in the proportioning barrel 4, so that the raw materials are evenly mixed together to form paint. When starting the spraying work, the steel plate 3 is conveyed to directly below the paint spraying head 7 through the conveying main body 2. Before the steel plate 3 is conveyed, the self-adjusting component can adjust the heights of the proportioning barrel 4 and the paint spraying head 7 according to the thickness of the steel plate 3, so that when spraying steel plates 3 with different thicknesses, the distance between the paint spraying head 7 and the steel plate 3 is always the same. When the steel plate 3 is conveyed to directly below the paint spraying head 7 through the conveying main body 2, the electric valve one 8 is controlled to start, so that the paint is sprayed onto the surface of the steel plate 3 through the paint spraying head 7, thus completing the entire spraying work. Through the above embodiments, through the stirring component, before the raw materials enter the proportioning barrel 4, the concentration can be always kept uniform. When some raw materials enter the inside of the proportioning barrel 4 for proportioning, the best concentration can be achieved, so that the proportioned paint can reach the best concentration, ensuring the comprehensive performance of the paint and improving the quality of spraying. The self-adjusting component can make the distance between the paint spraying head 7 and the steel plate 3 always the same when facing steel plates 3 with different thicknesses, ensuring the uniformity of painting, avoiding problems such as too thick or too thin coatings, and improving the overall quality of the product.

[0035] As Figures 2 to 4As shown, the stirring assembly includes a mixer 11 and multiple groups of stirrers 9. The mixer 11 is located inside the proportioning barrel 4, and multiple groups of stirrers 9 are respectively located inside multiple material barrels 6. Stirring rods 10 are fixedly connected between the outer walls of each group of stirrers 9, and a mixing rod 12 is fixedly connected between the inner sides of the mixer 11. A driving assembly is arranged above the stirring rods 10 and the mixing rod 12, and the driving assembly is used to drive the stirring rods 10 and the mixing rod 12 to rotate.

[0036] During operation: After various raw materials are respectively added into each material barrel 6, the driving assembly is started. The driving assembly will drive multiple stirring rods 10 to rotate. When the multiple stirring rods 10 rotate, the multiple stirrers 9 can stir and rotate inside the material barrel 6, and each raw material is continuously stirred and mixed, so that the concentration of the raw materials is the same everywhere inside the material barrel 6, avoiding stratification of the raw materials in the static state, resulting in different local concentrations and affecting the quality of the proportioned paint. And after the raw materials are respectively added into the proportioning barrel 4, the driving assembly drives the mixer 11 and the mixing rod 12 to rotate, so as to uniformly mix the raw materials together to form paint. And before spraying, the stirring assembly needs to keep moving to avoid stratification of the raw materials and paint inside the material barrel 6 and the proportioning barrel 4 due to being stationary.

[0037] As Figures 4 to 5 shown, the driving assembly includes a motor 13. A fixing frame 20 is fixedly connected to the top of the outer ring sleeve 5. The motor 13 is fixedly installed on the inner wall of the fixing frame 20. The output shaft of the motor 13 is fixedly connected with a rotating connecting piece 14. The inner wall of the rotating connecting piece 14 is rotatably connected with the outer wall of the mixing rod 12. An inner rotating gear 15 is fixedly connected to the outer wall of the mixer 11. An inner ring gear 16 is fixedly installed on the inner side surface of the top of the proportioning barrel 4. The teeth of the inner ring gear 16 mesh with the teeth of the inner rotating gear 15.

[0038] During operation: When the motor 13 is started, its output shaft will drive the rotating connecting piece 14 to rotate. The rotating connecting piece 14 will drive the mixing rod 12 and the inner rotating gear 15 to revolve inside the proportioning barrel 4. And during the revolution of the inner rotating gear 15, its teeth will mesh with the teeth of the inner ring gear 16, thereby driving the mixing rod 12 to rotate. Therefore, when the motor 13 is started, the mixing rod 12 and the mixer 11 can revolve and rotate inside the proportioning barrel 4. With the mutual cooperation of revolution and rotation, it is realized that the raw materials inside the proportioning barrel 4 can be uniformly mixed together. Compared with the existing stirring mechanism, the stirring effect can be improved, and all the raw materials inside the proportioning barrel 4 can be uniformly mixed.

[0039] As Figures 4 to 5As shown in the figure, a transmission double ring 17 is fixedly connected to the outer wall of the output shaft of the motor 13. A transmission ring 18 is fixedly connected to the top of each stirring rod 10. A transmission belt 19 is drivingly connected between every two symmetric transmission rings 18. The inner walls of the two transmission belts 19 are drivingly connected to the outer wall of the transmission double ring 17.

[0040] During operation: When the output shaft of the motor 13 rotates, it will drive the transmission double ring 17 to rotate. When the transmission double ring 17 rotates, it will drive each stirring rod 10 to rotate through the transmission belt 19 and the transmission ring 18, so that each stirring rod 10 and the stirrer 9 rotate. While stirring the raw materials to form paint, the raw materials in each material bucket 6 can be kept at the same concentration inside the material bucket 6. When some raw materials are added inside the proportioning bucket 4, the concentration of this raw material remains in the best state.

[0041] As Figures 7 to 9 shown in the figure, the self-adjusting component includes two mounting sliders 25. The two mounting sliders 25 are both fixedly installed on both sides of the spraying table 1. The inner walls of the two mounting sliders 25 are slidably connected with inner sliders 24. One side between the two inner sliders 24 is fixedly connected to the outer wall of the proportioning bucket 4. A slide bar groove 27 is formed on the side of the mounting slider 25. One side of the inner slider 24 is fixedly connected with a connecting rod 26. One side of the connecting rod 26 is fixedly connected with a jacking block 28. A jacking component for jacking up the jacking block 28 is arranged below the jacking block 28.

[0042] During operation: In the initial state, the distance between the spray head 7 and the spraying table 1 is the best spraying point for the paint. When the steel plate 3 is being transported by the conveying main body 2 and has not been sprayed yet, the steel plate 3 will first come into contact with the jacking component. The jacking component will make the jacking block 28 rise according to the thickness of the steel plate 3. The jacking block 28 will drive the inner slider 24 to slide upward inside the mounting slider 25, and the sliding distance of the inner slider 24 is the same as the thickness of the steel plate 3 to be sprayed. Therefore, during the upward movement of the inner slider 24, it will drive the proportioning bucket 4 and the spray head 7 to rise. After the spray head 7 rises, the distance between it and the top surface of the steel plate 3 can maintain the best spraying distance for the paint. And the whole adjustment process and the adjusted distance are determined by the thickness of the steel plate 3, which is applicable to steel plates 3 of any thickness. While improving the usage range of the device, the whole adjustment distance operation is simple, improving the coating quality and optimizing the spraying efficiency.

[0043] As Figures 7 to 9As shown in the figure, the jacking assembly includes inner sliding seats 30. Both of the two inner sliding seats 30 are fixedly installed on both sides of the painting table 1. An L-shaped frame 32 is slidably connected between the tops of the two inner sliding seats 30. Jacking balls 33 are symmetrically and fixedly connected to the top of the L-shaped frame 32. The jacking balls 33 are in contact with the bottom of the jacking block 28. A fixed rod 31 is fixedly connected to the inner wall of the L-shaped frame 32. An extrusion triangular block 29 is fixedly connected to the middle position of the fixed rod 31. The bottom of the extrusion triangular block 29 is in contact with the top of the conveying main body 2.

[0044] During operation: When the conveying main body 2 is conveying the steel plate 3, when the steel plate 3 first contacts the extrusion triangular block 29, due to the blockage of the extrusion triangular block 29, the steel plate 3 will squeeze the extrusion triangular block 29 to make it rise, and the rising distance is the same as the thickness of the steel plate 3. The extrusion triangular block 29 will drive the L-shaped frame 32 to rise. When the L-shaped frame 32 rises, it will drive the jacking balls 33 to rise. The jacking balls 33 will drive the jacking block 28 to rise, and the inner slider 24 will slide inside the installation slider 25. Therefore, the height of the paint spray head 7 changes, so that the best paint spraying distance is maintained between it and the steel plate 3.

[0045] As Figures 7 to 8 shown, a scraping plate 34 is fixedly connected between the two L-shaped frames 32. The bottom of the scraping plate 34 is in contact with the top of the conveying main body 2.

[0046] During operation: When the extrusion triangular block 29 drives the L-shaped frame 32 to rise after being squeezed and rising by the steel plate 3, it will also cause the scraping plate 34 to rise. And because the rising distance of the extrusion triangular block 29 is the same as the thickness of the steel plate 3, after the scraping plate 34 rises, it can fit to the top surface of the steel plate 3. During transportation, the scraping plate 34 can scrape off the dust that may exist on the surface of the steel plate 3, preventing the dust from contacting the paint during painting and affecting the adhesion of the paint to the surface of the steel plate 3.

[0047] As Figures 8 to 10 shown, bending plates 35 are symmetrically and slidably connected to the top of the painting table 1. Plugging rods 38 are fixedly connected to both sides of the bending plates 35. Vertical plates 40 are fixedly connected to the top of the painting table 1. The plugging rods 38 are plugged between the vertical plates 40. Limiting platforms 41 are fixedly connected to one ends of the plugging rods 38.

[0048] During operation: When the steel plate 3 is conveyed by the conveying main body 2, it will gradually enter between the two bending plates 35. The steel plate 3 slowly extrudes the two bending plates 35 outward, making the distance between the two bending plates 35 gradually increase, and making the plugging rods 38 slide inside the inner wall of the vertical plates 40. And the distance between the two bending plates 35 after expansion is the width of the steel plate 3. At the same time, it has a clamping effect on the steel plate 3, ensuring that the position of the steel plate 3 will not shift during transportation, so that the steel plate 3 can accurately pass under the jacking assembly and the paint spray head 7 during transportation.

[0049] As Figures 8 to 10 shown, a push plate 37 is fixedly connected to the top of the conveying main body 2. A return spring 39 is arranged outside the insertion rod 38. One end of the return spring 39 is fixedly connected to one side of the bending plate 35, and the other end of the return spring 39 is fixedly connected to one side of the vertical plate 40.

[0050] During operation: After the steel plate 3 is painted and transported away from the painting table 1, the two bending plates 35 will no longer be squeezed by the steel plate 3. Thus, under the action of the return spring 39, the two bending plates 35 can return to their original positions, facilitating the next use on a new steel plate 3. The push plate 37 can ensure that the conveying main body 2 can accurately push the extrusion triangular block 29 upward when conveying the push plate 37.

[0051] As Figures 8 to 10 shown, shielding plates 36 are fixedly connected to the tops of the two bending plates 35, and the shielding plates 36 are located on both sides below the paint spraying heads 7.

[0052] During operation: By means of the provided shielding plates 36, during the painting process, the paint can be protected to prevent some paint from spraying outside the painting table 1, thus affecting the working environment.

[0053] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
