Description
Technical Field
[0001] This invention relates to the field of spray painting equipment technology, specifically to a pre-processable spray painting equipment for furniture door panels. Background Technology
[0002] Solid wood furniture refers to furniture made of solid wood. Generally, solid wood furniture is divided into two types: pure solid wood furniture and all-solid wood furniture. Based on the type of wood used, solid wood furniture includes beech, teak, maple, oak, red cedar, ash, elm, poplar, and pine, among others. Beech, teak, and red cedar are considered the most valuable. my country's solid wood furniture industry is experiencing a positive development trend. According to the Zhiyan Data Research Center, with the continuous expansion of my country's solid wood furniture market, the industry will usher in a new development opportunity.
[0003] Current painting equipment used in wooden furniture production may result in excessive overlap or excessive paint application, leading to a significantly thicker paint layer at the overlap areas compared to other parts. This can cause drips or build-up, resulting in uneven painting that affects the appearance of the door panels and may even cause quality problems such as cracking and peeling. Furthermore, existing equipment has a slow paint drying speed after application, which seriously affects work efficiency. Summary of the Invention
[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a pre-processable door panel spraying equipment for furniture door panel production and processing, comprising a frame, the frame being a gantry frame design, a hydraulic cylinder being fixedly connected to the top of the frame, a connecting pipe being provided inside the frame, and a through hole being provided on the outside of the frame; The conveying assembly is located inside the frame and extends through the frame. Auxiliary components are slidably installed inside the frame near the conveyor components; The spraying assembly is located in the middle of the inside of the frame, above the conveying assembly, and is fixedly connected to the output end of the hydraulic cylinder. The spraying assembly includes a square plate slidably connected to a frame. A connecting hole is horizontally inserted through the square plate. A fixed cylinder is fixedly connected to the bottom of the square plate. The door panel to be processed is placed above the conveying assembly, which moves the door panel into the frame. As the door panel moves, a hydraulic cylinder moves the square plate downwards within the frame, causing the fixed cylinder and cylindrical tube at the bottom to move downwards, bringing the cylindrical tube closer to the material. At this point, paint enters the connecting hole through the connecting pipe, passes through the fixed cylinder and cylindrical tube, and finally exits from the spray nozzles on the curved plate, thus spraying the door panel. The elliptical design at the bottom of the spray nozzle concentrates more paint in the center and maintains a uniform distribution, ensuring better coverage and a thicker paint film in these key areas. This improves the wear resistance, corrosion resistance, and aesthetics of the center of the door panel. Furthermore, the elliptical design during spraying ensures that the paint is evenly distributed at overlapping points. The coating is more uniform, and the overlapping edges of adjacent sprays can achieve a smooth transition. There are no obvious boundaries or breaks in the paint distribution at the edges, making the entire sprayed surface look smoother and more natural. This reduces the need for repairs or rework due to improper edge treatment, thus saving time and costs and helping to improve the overall spraying quality and efficiency. The fixed cylinder is connected to the connecting hole, and the bottom of the inner wall of the fixed cylinder is threaded with a cylinder. The threaded connection between the cylinder and the fixed cylinder provides reliable connection strength through the interlocking of the threads, ensuring that the spray head will not loosen or fall off due to paint pressure, mechanical vibration, or other factors during the painting process. This ensures the stability and continuity of the painting work and also facilitates maintenance and replacement. The bottom of the cylinder is fixedly connected to an arc-shaped plate. The arc-shaped plate has an elliptical design, and multiple spray holes are opened inside the arc-shaped plate. The multiple spray holes are evenly distributed on the arc-shaped plate.
[0005] Preferably, the end of the connecting hole is fixedly connected to the end of the connecting pipe. The square plate has an I-beam design, and there are multiple fixed cylinders evenly distributed around the square plate. A sleeve is fixedly connected to the inner wall of the fixed cylinder near the inner wall of the cylinder. The sleeve has an inner cavity with a circular hole on its inner side. The inside of the inner cavity communicates with the inside of the sleeve through the circular hole. A compression spring is fixedly connected to the inner wall of the inner cavity near the inner wall of the cylinder. In the initial state, under the elastic force of the compression spring, the slide cylinder is located at the end of the sleeve away from the trapezoidal ring. Paint enters the interior of the connecting hole through the connecting pipe, and then the paint enters the interior of the slide cylinder. Under the pressure of the paint, the compression spring is compressed, causing the slide cylinder to... The sleeve moves towards the trapezoidal ring inside the inner cavity, allowing paint to enter the sleeve through the round holes. The paint then travels along the trapezoidal ring into the cylinder and is finally sprayed out through the nozzles on the arc-shaped plate. As the paint pressure increases, the sleeve continues to slide downwards inside the inner cavity, increasing the number of round holes that can feed paint. This increases the amount of paint entering the cylinder. By adjusting the pressure appropriately to control the paint volume, the amount of paint used can be matched to the actual needs, reducing paint consumption and saving costs. It also avoids repetitive or repair work due to excessive or insufficient paint application. When the pressure is properly adjusted, a single spray can achieve the desired effect. To achieve ideal paint coverage, the number of spraying operations and time are reduced, thereby improving work efficiency and saving labor and time costs. An L-shaped sliding cylinder is connected internally within the cavity. A fixing ring is fixedly connected to the outer side of the cylinder away from the sleeve, and the fixing ring is slidably connected to the inner wall of the fixing cylinder. A flow guide component is installed in the middle of the sleeve's interior. A trapezoidal ring is fixedly connected to the inner wall of the cylinder near the sleeve's end. By placing the trapezoidal ring at the connection between the fixing cylinder and the cylinder, the paint flow channel in the pipe before entering the cylinder gradually widens. As the paint flows, due to the gradual increase in the channel cross-sectional area, according to the principle of fluid continuity, its flow velocity... The flow rate gradually decreases, making the paint flow more stable and reducing turbulence and eddies that may occur due to excessive flow speed. This prevents the paint from forming a chaotic flow state within the pipe, ensuring that the paint flows smoothly towards the nozzle. Consequently, the paint is evenly distributed across the pipe cross-section, resulting in a finer and more uniform paint mist. This improves the quality and effect of the paint spraying, making the coating on the furniture surface smoother and flatter. The inner wall of the trapezoidal ring is fixedly connected with multiple guide plates, which are evenly distributed on the inner wall of the trapezoidal ring. The inner wall of the cylinder near the arc plate has a groove, and the diameter of the trapezoidal ring near the sleeve is the same as the inner diameter of the sleeve.
[0006] Preferably, the flow guiding assembly includes a fixed rod disposed in the middle of the interior of the fixed cylinder. A semi-circular body is fixedly connected to the end of the fixed rod, and the semi-circular body is fixedly connected to the end of the sleeve. Multiple rotating plates are fixedly connected to the outside of the fixed rod, and these rotating plates are evenly distributed around the fixed rod. By placing the rotating plates inside the sleeve, the multiple rotating plates can divide the paint flow within the sleeve into multiple smaller streams, making the paint flow more orderly, reducing turbulence and eddies, and helping to improve the stability of the paint flow. This ensures that the paint sprayed from the nozzle has a more uniform speed and direction, thereby improving the uniformity of the paint spraying. For accuracy, the rotating plate is located inside the sleeve, and an intermediate cylinder is set inside the cylinder. By setting the intermediate cylinder, the flow inside the cylinder is separated, making the paint stream in the middle and the side finer, so that it is easier to be atomized at the spray hole of the arc plate, making the paint atomized into finer and more uniform particles, forming a fine paint mist, which helps to improve the coating quality. The fixing rod passes through the fixing cylinder and extends into the interior of the intermediate cylinder. There are two sliders fixedly connected to the outside of the intermediate cylinder. The two sliders are symmetrically arranged with the intermediate cylinder as the center. The sliders are located inside the slot. A limit plate is fixedly connected to the outside of the fixing rod, and the limit plate is located inside the intermediate cylinder.
[0007] Preferably, the auxiliary component includes two intermediate rods. A fixing plate is fixedly connected to the end of each intermediate rod. Two fixing plates are also present, with both ends fixedly connected to the two intermediate rods. The fixing plates and intermediate rods are arranged alternately to form a quadrilateral. A round rod is fixedly connected to the top of each fixing plate. Since impurities on the door panel surface can form an isolation layer between the paint and the door panel, hindering direct contact between the paint and the door panel surface, the door panel to be processed is placed on a conveying assembly. The conveying assembly moves the door panel. As the door panel moves past the fixing plates, the elasticity of the spring plate causes the fixing plate to drive the bottom brush to clean the painted surface of the door panel. This cleaning removes impurities, allowing the paint to better adhere to the door panel surface, forming a strong coating and reducing paint peeling and flaking. After cleaning, the door panel is moved to the processing position. The hydraulic cylinder drives the square plate downwards. When the square plate contacts the middle rod, it stops moving downwards, so that the cylinder and the door panel are at a suitable distance. After the painting is finished, the door panel moves towards the discharge end. At this time, the heat generated by the heating plate can increase the temperature of the paint layer, accelerate the evaporation of solvents in the paint and the curing reaction of the paint, and greatly shorten the drying time. This helps to improve production efficiency, allowing the workpiece to enter the next production process faster, reducing the time the workpiece stays on the production line, and improving the overall production rhythm. The middle rod is located inside the through hole and is slidably connected to the through hole. A spring plate is fixedly connected to the top of the middle rod. The end of the spring plate away from the middle rod is fixedly connected to the inner wall of the through hole. A brush is fixedly connected to the bottom of the fixed plate. The brush is located near the feed end of the conveying component. A heating plate is fixedly connected to the bottom of the fixed plate. The heating plate is located near the discharge end of the conveying component.
[0008] Preferably, the conveying assembly includes a support frame, with side plates fixedly connected to the top of the support frame. A motor is fixedly connected to the outer side of each side plate. There are two side plates. A rotating shaft is rotatably connected to the opposite side of the side plates. The rotating shaft is fixedly connected to the output end of the motor. A transmission belt is rotatably connected to the outer side of the rotating shaft near the side plate. A roller is fixedly connected to the outer side of the rotating shaft. There are multiple rotating shafts, evenly distributed on the side plates, connected by the transmission belt. The door panel to be processed is placed on the roller. The motor, powered by an external power source, drives the rotating shaft to rotate, which in turn drives the roller to rotate, causing the roller to move the door panel. A collecting assembly is fixedly connected to the opposite side of the side plates, located below the roller. A material cylinder is located in the middle of the support frame, fixedly connected to the collecting assembly. There are two collecting assemblies, symmetrically arranged around the material cylinder. A round tube is fixedly connected to the outside of the material cylinder, and the end of the round tube is fixedly connected to the connecting pipe away from the connecting hole. An arc plate is fixedly connected inside the material cylinder. Residual paint falls onto the inclined plate. The rotating shaft rotates, which drives the scraper to rotate. The scraper contacts and squeezes the inclined plate. The inclined plate rotates towards the cleaning plate under force, causing the inclined plate to contact and collide with the bottom of the fixed column. As the rotating shaft continues to rotate, the inclined plate rotates back and forth and strikes. At this time, the paint remaining on the inclined plate will fall along the inclined plate into the inside of the arc plate in the material cylinder. The arc plate performs preliminary filtration of the recovered paint. The filtered paint returns to the inside of the material cylinder. Then, the paint enters the connecting pipe from the round tube for a new round of painting. Under the action of gravity, a rotating rod is connected to the inside of the material cylinder. A scraper is fixedly connected to the outside of the rotating rod. The outside of the scraper contacts the inner wall of the arc plate. The rotating rod and the rotating shaft are connected by belt drive.
[0009] Preferably, the collecting component includes a positioning plate, which is fixedly connected to the side plate. The positioning plate is located at the interval between the two side plates. There are two positioning plates. An inclined plate is rotatably connected to the opposite side of the positioning plate. A partition is fixedly connected to the top of the inclined plate. There are multiple partitions, which are evenly distributed on the positioning plate. The positioning plate has a sliding hole inside. A cleaning plate is slidably connected to the opposite side of the positioning plate. Because the residual material on the roller comes into contact with the other side of the material to be processed, it may affect the uniform distribution of the paint on the door panel, which may result in inconsistent paint color on the door panel. Under the elastic force of the return spring, the cleaning plate makes close contact with the outer side of the roller, so that the cleaning plate cleans the paint residue on the roller and avoids the paint residue on the roller affecting the subsequent door panel. This ensures that the paint adheres and transfers evenly on the door panel surface, making the color of each part of the door panel consistent, avoiding color difference, and improving the overall aesthetics of the door panel. The cleaning plate is located above the inclined plate, and a cylinder is slidably connected inside the sliding hole. The cylinder is fixedly connected to the cleaning plate and is symmetrically arranged with the cleaning plate as the center. A contact plate is fixedly connected to the opposite side of the positioning plate near the material cylinder. A fixing post is fixedly connected to the end of the cleaning plate near the inclined plate. The cylinder passes through the positioning plate through the sliding hole. A connecting plate is fixedly connected to the end of the cylinder away from the cleaning plate. A return spring is fixedly connected to the bottom of the cylinder. The end of the return spring away from the cylinder is fixedly connected to the sliding hole. A connecting rod is fixedly connected to the end of the connecting plate away from the cylinder. The two ends of the connecting rod are fixedly connected to the two connecting plates on both sides. The connecting rod is located below the inclined plate.
[0010] This invention provides a pre-treatment door panel painting equipment for furniture door panel production and processing. It has the following beneficial effects: I. This furniture door panel pre-treatment door panel spraying equipment, through its elliptical design, ensures a more uniform distribution of paint at overlapping areas during the spraying process. It also allows for a smooth transition at the overlapping edges of adjacent sprays, preventing obvious boundaries or breaks in paint distribution at the edges. This results in a smoother, more natural-looking sprayed surface, reducing the need for repairs or rework due to improper edge treatment. This saves time and costs, and helps improve overall spraying quality and efficiency.
[0011] II. The pre-processable door panel painting equipment for furniture door panel production and processing provides reliable connection strength through the threaded connection between the cylindrical and fixed cylinders and the mutual meshing of the threads. This ensures that the spray head will not loosen or fall off due to factors such as paint pressure and mechanical vibration during the painting process, thus guaranteeing the stability and continuity of the painting work. It is also easy to maintain and replace.
[0012] Third, the pre-treatment door panel spraying equipment for furniture door panel production and processing can control the amount of paint sprayed by reasonably adjusting the pressure, so that the amount of paint used can match the actual needs, reducing paint consumption and saving costs. At the same time, it can also avoid repetitive work or repair work due to too much or too little paint spraying. When the pressure is properly adjusted, the ideal paint coverage effect can be achieved in one spraying, reducing the number of spraying times and time, thereby improving work efficiency and saving labor and time costs.
[0013] IV. The pre-processable door panel painting equipment for furniture door panel production and processing, by setting a trapezoidal ring at the connection between the fixed cylinder and the cylindrical cylinder, gradually widens the paint flow channel in the pipe before entering the cylindrical cylinder, thereby making the paint flow more stable, reducing the turbulence and eddy current phenomena that may be caused by excessive flow velocity, avoiding the formation of a disordered flow state of the paint in the pipe, and ensuring that the paint can flow to the spray hole in a stable state.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0017] First embodiment, such as Figures 1 to 8 As shown, the present invention provides a technical solution: a pre-processable door panel spraying equipment for furniture door panel production and processing, including a frame 1, the frame 1 is a gantry frame design, a hydraulic cylinder 3 is fixedly connected to the top of the frame 1, a connecting pipe 4 is provided inside the frame 1, and a through hole 6 is opened on the outside of the frame 1. Conveying component 2 is located inside the frame 1 and extends through the frame 1; Auxiliary component 5 is slidably installed inside the frame 1 near the conveying component 2; Spraying component 7 is located in the middle of the inside of frame 1, above conveying component 2, and is fixedly connected to the output end of hydraulic cylinder 3. The spraying assembly 7 includes a square plate 71, which is slidably connected to the frame 1. A connecting hole 72 is opened inside the square plate 71, horizontally penetrating it. A fixing cylinder 73 is fixedly connected to the bottom of the square plate 71. The door panel to be processed is placed above the conveying assembly 2, which moves the door panel into the frame 1. As the door panel moves, the hydraulic cylinder 3 operates, causing the square plate 71 to move downwards inside the frame 1. This causes the fixing cylinder 73 and the cylindrical cylinder 74 at the bottom to move downwards, bringing the cylindrical cylinder 74 closer to the material. At this time, paint enters the connecting hole 72 through the connecting pipe 4, passes through the fixing cylinder 73 and the cylindrical cylinder 74, and finally exits from the spray nozzle on the arc-shaped plate 75, thus spraying the door panel. The elliptical design at the bottom of the spray nozzle concentrates more paint in the center and maintains a uniform distribution, ensuring better coverage and a thicker paint film in these key areas. This improves the wear resistance, corrosion resistance, and aesthetics of the center of the door panel. Simultaneously, the elliptical design allows for better paint coverage during the spraying process. The paint distribution at overlapping positions is more uniform, and a smooth transition can be achieved at the overlapping edges of adjacent sprays. There are no obvious boundaries or breaks in the paint distribution at the edges, making the entire sprayed surface look smoother and more natural. This reduces the need for repairs or rework due to improper edge treatment, thereby saving time and costs and helping to improve the overall spraying quality and efficiency. The fixed cylinder 73 is connected to the connecting hole 72. The bottom of the inner wall of the fixed cylinder 73 is threadedly connected to the cylinder 74. The threaded connection between the cylinder 74 and the fixed cylinder 73 provides reliable connection strength through the mutual meshing of the threads, ensuring that the spray head will not loosen or fall off due to paint pressure, mechanical vibration, or other factors during the painting process. This ensures the stability and continuity of the painting work and also facilitates maintenance and replacement. The bottom of the cylinder 74 is fixedly connected to an arc plate 75. The arc plate 75 has an elliptical design and spray holes 76 are opened inside the arc plate 75. There are multiple spray holes 76, which are evenly distributed on the arc plate 75.
[0018] The end of the connecting hole 72 is fixedly connected to the end of the connecting pipe 4. The square plate 71 is designed in an I-shape. There are multiple fixing cylinders 73, which are evenly distributed around the square plate 71. A sleeve 77 is fixedly connected to the inner wall of the fixing cylinder 73 near the inner wall of the cylinder 74. The sleeve 77 has an inner cavity 78, and a round hole 711 is opened on the inner side of the inner cavity 78. The interior of the inner cavity 78 communicates with the interior of the sleeve 77 through the round hole 711. A compression spring 712 is fixedly connected to the inner wall of the inner cavity 78 near the inner wall of the cylinder 74. In the initial state, under the elastic force of the compression spring 712, the slide cylinder 710 is located at the end of the sleeve 77 away from the trapezoidal ring 716. Paint enters the interior of the connecting hole 72 through the connecting pipe 4, and then the paint enters the interior of the slide cylinder 710. Under pressure, the compression spring 712 is compressed, causing the slide cylinder 710 to move closer to the trapezoidal ring 716 inside the inner cavity 78. This allows paint to enter the sleeve 77 through the round hole 711, and then the paint enters the cylinder 74 along the trapezoidal ring 716, finally being sprayed out through the spray hole 76 on the arc plate 75. As the paint pressure increases, the slide cylinder 710 continues to slide downward inside the inner cavity 78, increasing the number of round holes 711 that can feed the paint. At this time, the amount of paint entering the cylinder 74 increases. By reasonably adjusting the pressure to control the amount of paint sprayed, the amount of paint used can be matched with the actual needs, reducing paint consumption, saving costs, and avoiding repetition due to excessive or insufficient paint spraying. When the pressure is properly adjusted, a single spray can achieve the desired paint coverage, reducing the number of sprays and the time required, thus improving work efficiency and saving labor and time costs. The inner cavity 78 has a sliding connection to a slide cylinder 710, which is L-shaped. A fixing ring 714 is fixedly connected to the outer side of the slide cylinder 710 away from the sleeve 77. The fixing ring 714 is slidably connected to the inner wall of the fixing cylinder 73. A flow guide component 79 is installed in the middle of the inner cavity of the sleeve 77. A trapezoidal ring 716 is fixedly connected to the inner wall of the cylinder 74 near the sleeve 77. By setting the trapezoidal ring 716 at the connection between the fixing cylinder 73 and the cylinder 74, the paint flow channel in the pipe before entering the cylinder 74 gradually widens. During the process, as the cross-sectional area of the channel gradually increases, the flow velocity gradually decreases according to the principle of fluid continuity, thus making the paint flow more stable. This reduces turbulence and eddies that may occur due to excessive flow velocity, preventing the paint from forming a chaotic flow state within the pipe. This ensures that the paint flows smoothly towards the nozzle, promoting uniform distribution of the paint across the pipe cross-section, resulting in a finer and more uniform paint mist. This improves the quality and effect of the paint spraying, making the coating on the furniture surface smoother and flatter. A guide plate 713 is fixedly connected to the inner wall of the trapezoidal ring 716. Multiple guide plates 713 are evenly distributed on the inner wall of the trapezoidal ring 716. A groove 715 is provided on the inner wall of the cylinder 74 near the end of the arc-shaped plate 75.The diameter of the trapezoidal ring 716 at the end near the sleeve 77 is the same as the inner diameter of the sleeve 77.
[0019] The flow guiding assembly 79 includes a fixed rod 791, which is located in the middle of the interior of the fixed cylinder 73. A semi-circular body 792 is fixedly connected to the end of the fixed rod 791, and the semi-circular body 792 is fixedly connected to the end of the sleeve 77. A rotating plate 793 is fixedly connected to the outside of the fixed rod 791. Multiple rotating plates 793 are evenly distributed around the fixed rod 791. By setting the rotating plates 793 inside the sleeve 77, the multiple rotating plates 793 can divide the paint flow within the sleeve 77 into multiple smaller streams, making the paint flow more orderly, reducing turbulence and eddies, and helping to improve the stability of the paint flow. This ensures that the paint sprayed from the nozzle has a more uniform speed and direction, thereby improving the uniformity and accuracy of the paint spraying. Inside the sleeve 77, the cylinder 74 has an intermediate cylinder 794. By setting the intermediate cylinder 794, the flow inside the cylinder 74 is separated, making the paint stream in the middle and the side finer. This makes it easier to atomize at the spray hole 76 of the arc plate 75, making the paint atomize into finer and more uniform particles, forming a delicate paint mist, which helps to improve the coating quality. The fixing rod 791 passes through the fixing cylinder 73 and extends into the interior of the intermediate cylinder 794. There are two sliders 796 fixedly connected to the outside of the intermediate cylinder 794. The two sliders 796 are symmetrically arranged with the intermediate cylinder 794 as the center. The sliders 796 are located inside the slot 715. The fixing rod 791 is fixedly connected to the outside of the limiting plate 795, which is located inside the intermediate cylinder 794.
[0020] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figure 9As shown, the auxiliary component 5 includes two intermediate rods 51. A fixing plate 52 is fixedly connected to the end of each intermediate rod 51. Two fixing plates 52 are also fixedly connected to both ends of each fixing plate 52. The fixing plates 52 and intermediate rods 51 are arranged alternately to form a quadrilateral. A round rod 53 is fixedly connected to the top of each fixing plate 52. Since impurities on the door panel surface form an isolation layer between the paint and the door panel, hindering direct contact between the paint and the door panel surface, the door panel to be processed is placed on the conveying component 2. The conveying component 2 moves the door panel. When the door panel moves past the fixing plate 52, under the elastic force of the spring plate 54, the fixing plate 52 drives the bottom brush 56 to clean the painted surface of the door panel. Cleaning removes these impurities, allowing the paint to better adhere to the door panel surface, forming a strong coating and reducing paint peeling and other problems. After cleaning, the door panel is moved to the processing position, and hydraulic pressure... Cylinder 3 drives square plate 71 to move downward. When square plate 71 contacts intermediate rod 51, it stops moving downward, so that cylinder 74 and door panel are at a suitable distance. After painting, door panel moves towards the discharge end. At this time, the heat generated by heating plate 55 can increase the temperature of paint layer, accelerate the evaporation of solvent in paint and the curing reaction of paint, and greatly shorten drying time. This helps to improve production efficiency, so that workpieces can enter the next production process faster, reduce the dwell time of workpieces on the production line, and improve the overall production rhythm. Intermediate rod 51 is located inside through hole 6 and is slidably connected to through hole 6. Spring plate 54 is fixedly connected to the top of intermediate rod 51. The end of spring plate 54 away from intermediate rod 51 is fixedly connected to the inner wall of through hole 6. Brush 56 is fixedly connected to the bottom of fixed plate 52. Brush 56 is located near the feed end of conveying component 2. Heating plate 55 is fixedly connected to the bottom of fixed plate 52. Heating plate 55 is located near the discharge end of conveying component 2.
[0021] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 10 to 13As shown, the conveying assembly 2 includes a support 21. A side plate 22 is fixedly connected to the top of the support 21. A motor 26 is fixedly connected to the outer side of the side plate 22. There are two side plates 22. A rotating shaft 23 is rotatably connected to the opposite side of the side plates 22. The rotating shaft 23 is fixedly connected to the output end of the motor 26. A transmission belt 25 is rotatably connected to the outer side of the rotating shaft 23 near the side plate 22. A roller 24 is fixedly connected to the outer side of the rotating shaft 23. There are multiple rotating shafts 23, which are evenly distributed on the side plates 22. The multiple rotating shafts 23 are connected by the transmission belt 25. Next, the door panel to be processed is placed on the roller 24. The motor 26 is connected to an external power source and operates, driving the rotating shaft 23 to rotate. The rotating shaft 23 drives the electric roller 24 to rotate, causing the roller 24 to move the door panel. A collection assembly 27 is fixedly connected to the opposite side of the side panel 22. The collection assembly 27 is located below the roller 24. A material cylinder 28 is set in the middle of the inside of the bracket 21. The material cylinder 28 is fixedly connected to the collection assembly 27. There are two collection assemblies 27, which are symmetrically arranged with the material cylinder 28 as the center. The outer side of the material cylinder 28 is fixed. A round tube 29 is connected, and the end of the round tube 29 is fixedly connected to the end of the connecting tube 4 away from the connecting hole 72. An arc plate 210 is fixedly connected inside the material cylinder 28. Residual paint falls onto the inclined plate 272. The rotating shaft 23 rotates, thereby driving the scraper 212 to rotate. The scraper 212 contacts and squeezes the inclined plate 272. The inclined plate 272 is forced to rotate towards the cleaning plate 274, causing the inclined plate 272 to contact and collide with the bottom of the fixed column 278. As the rotating shaft 23 continues to rotate, the inclined plate 272 reciprocates and strikes. At this time, the inclined plate... The paint remaining on plate 272 will fall along the inclined plate 272 into the arc plate 210 inside the barrel 28. The arc plate 210 is set to perform preliminary filtration of the recovered paint. The filtered paint returns to the inside of the barrel 28. Then the paint enters the connecting pipe 4 through the round pipe 29 for a new round of painting. Under the action of gravity, the barrel 28 is rotatably connected to the rotating rod 211. The outside of the rotating rod 211 is fixedly connected to the scraper 212. The outside of the scraper 212 contacts the inner wall of the arc plate 210. The rotating rod 211 and the rotating shaft 23 are connected by belt drive.
[0022] The collecting component 27 includes a positioning plate 271, which is fixedly connected to the side plate 22. The positioning plate 271 is located at the interval between the two side plates 22. There are two positioning plates 271. An inclined plate 272 is rotatably connected to the opposite side of the positioning plate 271. A partition 276 is fixedly connected to the top of the inclined plate 272. There are multiple partitions 276, which are evenly distributed on the positioning plate 271. A sliding hole 273 is opened inside the positioning plate 271. A cleaning plate 274 is slidably connected to the opposite side of the positioning plate 271. Since the residual material on the roller 24 comes into contact with the other side of the material to be processed, it may affect the uniform distribution of the paint on the door panel, which may result in inconsistent paint color on the door panel. Under the elastic force of the return spring 2710, the cleaning plate 274 is in close contact with the outer side of the roller 24, so that the cleaning plate 274 cleans the paint residue on the roller 24, avoiding the impact of the paint residue on the roller 24 on the subsequent door panel. This ensures that the paint adheres and transfers evenly on the door panel surface, making the color of each part of the door panel consistent, avoiding color difference, and improving the overall aesthetics of the door panel. The cleaning plate 274 is located above the inclined plate 272. A cylinder 277 is slidably connected inside the sliding hole 273. The cylinder 277 is fixedly connected to the cleaning plate 274. The cylinder 277 is symmetrically arranged with the cleaning plate 274 as the center. The positioning plate 271 is close to the material cylinder 2. A contact plate 275 is fixedly connected to the opposite side of one end of the 8. A fixed post 278 is fixedly connected to the end of the cleaning plate 274 near the inclined plate 272. A cylinder 277 passes through the positioning plate 271 via a sliding hole 273. A connecting plate 2711 is fixedly connected to the end of the cylinder 277 away from the cleaning plate 274. A return spring 2710 is fixedly connected to the bottom of the cylinder 277. The end of the return spring 2710 away from the cylinder 277 is fixedly connected to the sliding hole 273. A connecting rod 279 is fixedly connected to the end of the connecting plate 2711 away from the cylinder 277. The two ends of the connecting rod 279 are fixedly connected to the two connecting plates 2711 on both sides. The connecting rod 279 is located below the inclined plate 272.
[0023] In use, the door panel to be processed is placed on the roller 24. The motor 26 is powered by an external power source. The motor 26 drives the rotating shaft 23 to rotate, which in turn drives the roller 24 to rotate, causing the roller 24 to move the door panel. The door panel moves under the fixed plate 52. Under the elastic force of the spring plate 54, the fixed plate 52 drives the bottom brush 56 to clean the painted surface of the door panel. As the door panel moves, the hydraulic cylinder 3 drives the square plate 71 to move downward inside the frame 1. The square plate 71 drives the bottom fixed cylinder 73 and the cylindrical cylinder 74 to move downward, so that the cylindrical cylinder 74 is close to the material. At this time, the paint enters the interior of the connecting hole 72 through the connecting pipe 4, passes through the fixed cylinder 73 and the cylindrical cylinder 74, and finally exits from the spray hole on the arc plate 75, thus spraying the door panel. After the painting is completed, the door panel moves towards the discharge end. At this time, the heat generated by the heating plate 55 can increase the temperature of the paint layer, accelerate the evaporation of the solvent in the paint and the curing reaction of the paint.
[0024] The remaining paint falls onto the inclined plate 272, and the rotating shaft 23 rotates, which in turn drives the scraper 212 to rotate. The scraper 212 contacts and squeezes the inclined plate 272, causing the inclined plate 272 to rotate in the direction of the cleaning plate 274. This causes the inclined plate 272 to contact and collide with the bottom of the fixed column 278. As the rotating shaft 23 continues to rotate, the inclined plate 272 reciprocates and strikes. At this time, the remaining paint on the inclined plate 272 will fall along the inclined plate 272 into the inside of the barrel 28.
