Description

Technical Field

[0001] This utility model relates to the field of automotive interior coating technology, and in particular to a noise reduction and purification device for automotive interior coating. Background Technology

[0002] With the rapid development of the automotive industry, consumers have increasingly higher demands for the comfort, aesthetics, and functionality of car interiors. To meet these demands, automotive interior parts typically require surface coating during the production process. Applying specific functional coatings not only gives interior parts a variety of colors and textures, but more importantly, it can achieve noise reduction (such as absorbing vibration and noise) and purification (such as antibacterial and deodorizing) effects, thereby significantly improving the driving and riding experience.

[0003] Currently, existing spraying methods utilize automated spraying equipment, but these are mostly single-function, independent units, with the spraying process and subsequent curing and drying steps spatially separated. This segmented processing method requires workpieces to be transferred between different workstations, which not only prolongs the overall production cycle and increases the risk of bumps and knocks during the handling of semi-finished products, but also makes the undried paint surface highly susceptible to dust accumulation during the transfer process, severely affecting the final spraying quality. To address these issues, we have introduced a noise reduction and purification device for automotive interior spraying. Utility Model Content

[0004] This utility model discloses a noise reduction and purification device for automotive interior painting, aiming to solve the problem that existing painting methods use automated painting equipment, but these are mostly single-function independent units, with painting and subsequent curing and drying processes separated spatially. This segmented processing method requires workpieces to be transferred between different workstations, which not only prolongs the overall production cycle and increases the risk of bumps and knocks during the handling of semi-finished products, but also makes the undried paint surface extremely susceptible to dust accumulation during the transfer process, seriously affecting the final painting quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A noise reduction and purification device for automotive interior painting includes a painting box. A drive motor is fixedly connected to one side of the inner wall of the painting box. A painting mechanism is installed inside the painting box. The painting mechanism includes a painting component, a conveying component, and a drying component, which cooperate with each other. The painting component includes slide rails symmetrically fixedly connected to the top of the painting box. Sliding blocks are slidably connected to the top of each of the two slide rails. A cylinder is fixedly connected to the top of the painting box. A clearance groove is provided on the top of the painting box. A rotating shaft is rotatably connected inside the painting box. A connecting frame is symmetrically fixedly connected to the outer side. Each of the two connecting frames has a rolling groove inside. A rolling wheel is rotatably connected inside each of the two rolling grooves. A sliding column is symmetrically rotatably connected to the outer side of each of the two rolling wheels. One end of each sliding column is fixedly connected to a sliding block. A connecting plate is fixedly connected between the two sliding columns. One side of the connecting plate is fixedly connected to the telescopic end of a cylinder. A liquid storage tank is fixedly connected between the two connecting frames. A micro-pump is installed inside the liquid storage tank. Atomizing nozzles are fixedly connected in a rectangular array at the bottom of the liquid storage tank. The atomizing nozzles and the micro-pump inside the liquid storage tank work together.

[0007] The spraying mechanism allows for rapid and uniform spraying of automotive interior panels, integrating spraying and drying into the same equipment. This shortens the production cycle, avoids costly handling and damage, improves spraying quality, and features a simple structure with strong practicality.

[0008] In a preferred embodiment, the conveying assembly includes drive shafts symmetrically rotatably connected inside the spray box. Conveyor rollers are fixedly connected to the outer sides of both drive shafts, and a first conveyor belt is fitted onto the outer sides of the two conveyor rollers.

A second pulley is fixedly connected to the output end of the drive motor, and the first and second pulleys are connected by a timing belt drive.

[0009] The conveyor assembly adopts a single-motor drive design. The drive motor drives the transmission shaft to rotate synchronously through the pulley, ensuring the smooth operation of the No. 1 conveyor belt. This provides precise cycle control for the spraying and drying processes and avoids quality problems caused by asynchronous conveying.

[0010] In a preferred embodiment, the drying assembly includes a drive motor fixedly connected to the back of the spray box, support rollers symmetrically rotatably connected inside the spray box, a second conveyor belt sleeved on the outer side of the two support rollers, one of the two support rollers fixedly connected to the output end of the drive motor, and a drying box fixedly connected to the top of the inner wall of the spray box and above the second conveyor belt.

[0011] The drying unit is driven by an independent drive motor to run the second conveyor belt. The drying box is located directly above the conveyor belt, which can achieve immediate drying after spraying, effectively preventing dust from sticking to the paint surface, shortening the production cycle, and ensuring product quality.

[0012] In a preferred embodiment, the spray box has an inlet at one end and an outlet at the other end.

[0013] The entire machine is designed with inlet and outlet to form a continuous production line.

[0014] In a preferred embodiment, the front of the spray box is provided with an observation window.

[0015] The observation window facilitates real-time monitoring.

[0016] In a preferred embodiment, a controller is fixedly connected to the front of the spray box, and the drive motor, cylinder, transmission motor and drying box are all electrically connected to the controller.

[0017] The controller centrally controls all actuators, achieving a high degree of automation and intelligent operation, which greatly improves production efficiency and ease of operation.

[0018] The noise reduction and purification device for automotive interior painting provided by this utility model has the following advantages:

[0019] Firstly, the spraying mechanism allows for rapid and uniform spraying of automotive interior panels, integrating spraying and drying into the same equipment. This shortens the production cycle, avoids costly handling and damage, improves spraying quality, and features a simple structure with strong practicality.

[0030] The noise reduction and purification device for automotive interior painting disclosed in this utility model is mainly applied to automotive interior painting scenarios.

[0031] Reference Figure 1 - Figure 7A noise reduction and purification device for automotive interior painting includes a painting box 1. A drive motor 2 is fixedly connected to one side of the inner wall of the painting box 1. The painting box 1 is equipped with a painting mechanism, which includes a painting component, a conveying component, and a drying component. The painting component, conveying component, and drying component work together. The painting component includes slide rails 31, which are symmetrically fixedly connected to the top of the painting box 1. Sliding blocks 34 are slidably connected to the top of each slide rail 31. A cylinder 32 is fixedly connected to the top of the painting box 1. A clearance groove 33 is provided on the top of the painting box 1. A rotating shaft 37 is rotatably connected inside the painting box 1. Connecting frames are symmetrically fixedly connected to the outer side of the rotating shaft 37. 38. Each of the two connecting frames 38 has a rolling groove 311 inside. Rolling wheels 312 are rotatably connected inside the two rolling grooves 311. Sliding columns 36 are symmetrically rotatably connected to the outer sides of the two rolling wheels 312. One end of the sliding column 36 is fixedly connected to the sliding block 34. A connecting plate 35 is fixedly connected between the two sliding columns 36. One side of the connecting plate 35 is fixedly connected to the telescopic end of the cylinder 32. A liquid storage tank 39 is fixedly connected between the two connecting frames 38. A micro pump is installed inside the liquid storage tank 39. Atomizing nozzles 310 are fixedly connected in a rectangular array at the bottom of the liquid storage tank 39. The atomizing nozzles 310 and the micro pump inside the liquid storage tank 39 work together. The conveying assembly includes drive shafts 41, which are symmetrically rotatably connected inside the spray box 1. Conveyor rollers 44 are fixedly connected to the outer sides of both drive shafts 41. A first conveyor belt 43 is fitted around the outer sides of the two conveyor rollers 44. One end of each drive shaft 41 extends to the outer side of the spray box 1 and is fixedly connected to a first pulley 42. A second pulley 45 is fixedly connected to the output end of the drive motor 2. The first pulley 42 and the second pulley 45 are connected by a timing belt. The drying assembly includes a drive motor 51, which is fixedly connected to the back of the spray box 1. Support rollers 52 are symmetrically rotatably connected inside the spray box 1. A second conveyor belt 53 is fitted around the outer sides of the two support rollers 52. One of the two support rollers 52 is fixedly connected to the output end of the drive motor 51. A drying chamber 54 is fixedly connected to the top of the inner wall of the spray box 1, above the second conveyor belt 53.

[0032] In this embodiment: the drive motor 2 drives the first pulley 42 to rotate via the timing belt, causing the first conveyor belt 43 to uniformly feed the workpiece into the spray box 1. Simultaneously, the cylinder 32 reciprocates according to programmed instructions, pushing the connecting plate 35 and the sliding column 36 to move. The sliding column 36 drives the rolling wheel 312 to roll within the rolling groove 311 of the connecting frame 38, thereby forcing the connecting frame 38 and the rotating shaft 37 to oscillate back and forth, ultimately causing the liquid storage tank 39 and the atomizing nozzle 310 below it to oscillate. The micro-pump inside the liquid storage tank 39 delivers the paint to the atomizing nozzle 310 and atomizes it for uniform spraying onto the passing workpiece. After the workpiece is sprayed, it is immediately transferred to the second conveyor belt 53. The drive motor 51 drives the second conveyor belt 53 to transport the workpiece directly below the drying chamber 54. The hot air generated by the drying chamber 54 quickly dries and cures the surface of the workpiece. Through the set spraying mechanism, the automotive interior panels can be sprayed quickly and evenly. Spraying and drying are integrated into the same equipment, which shortens the production cycle, avoids the bumps and knocks during handling, improves the spraying quality, and has a simple structure and strong practicality.

[0033] In the above technical solution, considering that existing spraying methods use automated spraying equipment, but these are mostly single-function independent units, the spraying and subsequent curing and drying processes are spatially separated. This segmented processing method requires the workpiece to be transferred between different workstations, which not only prolongs the overall production cycle and increases the risk of bumps and knocks during the handling of semi-finished products, but also makes the undried paint surface extremely susceptible to dust accumulation during the transfer process, seriously affecting the final spraying quality. To solve these problems, the specific operation is as follows:

[0034] Reference Figure 1 - Figure 7 In a preferred embodiment, the spray box 1 has an inlet 7 at one end and an outlet 6 at the other end. An observation window 8 is provided on the front of the spray box 1. A controller 9 is fixedly connected to the front of the spray box 1, and the drive motor 2, cylinder 32, transmission motor 51, and drying chamber 54 are all electrically connected to the controller 9.

[0035] In this embodiment, the whole machine adopts an inlet 7 and an outlet 6 to form a continuous production line. The observation window 8 facilitates real-time monitoring, and the controller 9 centrally controls each actuator, realizing highly automated and intelligent operation, which greatly improves production efficiency and ease of operation.

[0036] Working Principle: The operator first sets the program through the controller 9, and then places the automotive interior parts to be painted onto the first conveyor belt 43 through the inlet 7. The device is started, and the drive motor 2 drives the first pulley 42 to rotate via the timing belt, causing the first conveyor belt 43 to uniformly feed the workpiece into the painting box 1. Simultaneously, the cylinder 32 reciprocates according to the program instructions, pushing the connecting plate 35 and the sliding column 36 to move. The sliding column 36 drives the rolling wheel 312 to roll within the rolling groove 311 of the connecting frame 38, thereby forcing the connecting frame 38 and the rotating shaft 37 to oscillate back and forth, ultimately causing the liquid storage tank 39 and the atomizing nozzle 310 below it to oscillate. The micro-pump in the liquid storage tank 39 delivers the paint to the atomizing nozzle 310 and atomizes it, uniformly spraying the passing workpiece. After spraying, the workpiece is transferred to conveyor belt 53. The drive motor 51 drives conveyor belt 53 to transport the workpiece directly below the drying chamber 54. The hot air generated by the drying chamber 54 quickly dries and cures the surface of the workpiece. Finally, the finished workpiece is sent out from outlet 6, thus completing the entire automated spraying and drying process.

[0037] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
