Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, specifically to an automotive parts painting device. Background Technology

[0002] Automotive parts are the various units that make up the overall automotive parts processing, as well as the products that serve automotive parts processing. According to a novel automotive parts spraying device disclosed on the State Intellectual Property Office website (authorization announcement number: CN111266239), A) describes a novel automotive parts spraying device, specifically relating to the field of spraying technology. It includes a spraying chamber, a primer tank, and spray nozzles. Mounting brackets are provided on both the left and right sides of the lower end of the spraying chamber. A track is provided in the lower part of the spraying chamber. An inlet is provided on the lower right wall of the spraying chamber, corresponding to the track. An outlet is provided on the lower left wall of the spraying chamber, corresponding to the track. A primer tank is provided on the upper right side of the spraying chamber, and a topcoat tank is provided on the left side of the primer tank. In this invention, the control valve of the inlet pipe at the lower end of the primer tank is opened, allowing the primer to enter the inlet pipe. After being pressurized by a pressure pump, the paint in the inlet pipe is flushed into a distribution pipe. Through the action of the spray nozzles at the lower end of the distribution pipe, the paint is sprayed out from the nozzles to apply primer to the automotive parts. This is beneficial for the spraying of automotive parts. The multiple spray nozzles help to expand the paint spraying area and improve the efficiency of paint spraying.

[0003] Based on the above, the inventor believes that the following defects exist: This new type of automotive parts spraying device sprays topcoat onto automotive parts through the nozzles on the left spray head during use, which is beneficial for the spraying of automotive parts. However, since common spraying devices are often fixed in place, there may be blind spots in the spraying process, resulting in uneven spraying of automotive parts and failure to achieve good processing quality, which in turn affects the further processing of automotive parts. Therefore, it is necessary to design an automotive parts spraying device that is highly practical and can spray evenly. Summary of the Invention

[0004] The purpose of this invention is to provide an automotive parts painting device to solve the problems mentioned in the background art.

The output shaft and the mixing shaft are rotatably connected to the inner walls of the first through hole and the second through hole, which facilitates the mixing of raw materials while driving the automotive parts to rotate, thereby achieving the purpose of uniform spraying.

[0009] According to the above technical solution, the clamping mechanism includes a connecting box, which is disposed on the inner wall of the spray box.

[0014] According to the above technical solution, the filter frame has a rectangular opening on the front that matches the filter frame, the sealing plate is inserted into the inner wall of the rectangular opening, and a pull rod is fixedly connected to the front of the sealing plate so that the sealing plate can achieve the purpose of sealing.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. This invention, by incorporating a rotating mechanism, enables the motor to operate. The motor's output end drives the output shaft to rotate, which in turn drives the support shaft to rotate via a transmission assembly. The support shaft, through a drive gear and a driven gear, drives the mixing shaft to rotate, thereby causing the mixing block to move in a circular motion. This stirs and mixes the raw materials, allowing for better dilution and mixing, achieving a high-quality mixture. The rotation of the output shaft also causes the automotive parts, held by a limit clamp, to rotate. Simultaneously, a water pump is activated, allowing the pump to transport the mixed materials from the partition box to the output pipe via a suction pipe. The materials are then sprayed through the nozzles via the output pipe, uniformly coating the automotive parts and achieving a high-quality coating without any dead spots. This facilitates further processing of the automotive parts and enhances the practicality of the device.

[0016] 2. This invention, by providing a clamping mechanism, allows the handwheel at the front end of the rotating shaft to drive the threaded shaft to rotate, thereby converting the rotational motion of the threaded shaft into the linear motion of the connecting plate. The connecting plate, via its long shaft, drives the clamping block to move closer to the inside of the automotive part. When the outer side of the clamping block contacts the inner side of the automotive part, it can clamp and limit the automotive part, thereby achieving the limitation and fixation of the automotive part. This makes the automotive part more stable during the painting process, achieving good painting efficiency and further improving the stability of the automotive part during the painting process.

[0017] 3. This invention, by incorporating a filtration mechanism, draws exhaust gas into the filter frame upon startup. The gas is then filtered and purified by the sealing plate, blocking harmful substances and allowing the purified gas to be discharged without impacting the surrounding environment, thus achieving a healthy working environment. Furthermore, during prolonged use, when the purification plate needs to be disassembled and replaced, the sealing plate is first moved forward by the pull rod on its front side, releasing the first and second magnetic blocks from their limiting positions. Simultaneously, the sealing plate causes the long block to slide out of the fixing groove, further removing the purification plate from the filter frame and achieving efficient disassembly. This also facilitates operation and enhances the flexibility of the device. Attached Figure Description

[0027] Furthermore, the connecting plate 56 is slidably connected to the inner wall of the connecting box 51. The front of the connecting box 51 is provided with a third through hole that matches the rotating shaft 55. The rotating shaft 55 is rotatably connected to the inner wall of the third through hole. A handwheel is fixedly connected to the front end of the rotating shaft 55, and the rotating shaft 55 can be driven to rotate stably through the handwheel. Example 3

[0028] See Figures 1 to 6 Based on Embodiments 1 and 2, the filter mechanism 6 further includes a filter frame 61, which is fixedly connected to the top of the spray box 2. A fixing groove 62 is fixedly connected to the inner wall of the filter frame 61. A long block 63 is slidably connected inside the fixing groove 62. A sealing plate 64 is fixedly connected to the front of the long block 63. A purification plate 65 is fixedly connected to the inner side of the long block 63. An induced draft fan 66 is fixedly connected to the top of the spray box 2, which facilitates the purification of the waste gas generated during the spraying process.

[0029] Furthermore, the filter frame 61 has a connecting groove on its front side, and a first magnetic block is fixedly connected to the inner wall of the connecting groove. A second magnetic block is provided on the front side of the first magnetic block. The second magnetic block is fixedly connected to the outer side of the sealing plate 64. The front side of the first magnetic block and the back side of the second magnetic block are in contact, and the sides of the two in contact with each other have opposite magnetic poles, which facilitates the installation and removal of the purification plate 65.

[0030] Furthermore, the filter frame 61 has a rectangular opening on the front that matches the filter frame 61, and the sealing plate 64 is inserted into the inner wall of the rectangular opening. A pull rod is fixedly connected to the front of the sealing plate 64 so that the sealing plate 64 can achieve the purpose of sealing. In actual operation, when this device is used, the operator can first open the sealed door on the front of the spray box 2, then place the inner side of the car parts to be sprayed on the outer side of the clamping block 58, and then drive the threaded shaft 52 to rotate by shaking the handwheel at the front end of the rotating shaft 55. This allows the rotational motion of the threaded shaft 52 to be converted into the linear motion of the connecting plate 56. The connecting plate 56 then drives the clamping block 58 to move closer to the inner side of the car parts through the long shaft 57. When the outer side of the clamping block 58 contacts the inner side of the car parts, it can clamp and limit the car parts, thereby achieving the limitation and fixation of the car parts. This makes the car parts more stable during the spraying process, achieving good spraying efficiency and further improving the stability of the car parts during the spraying process. After the automotive parts are fixed in place, the operator can open the sealing plug 3 to inject the material to be sprayed into the partition box 401. Then, the sealing plug 3 is reset, and the motor 42 is started. The output end of the motor 42 drives the output shaft 43 to rotate. The output shaft 43, through the transmission assembly 44, drives the support shaft 45 to rotate. The support shaft 45, through the drive gear 46 and the driven gear 47, drives the mixing shaft 48 to rotate, thereby causing the mixing shaft 48 to drive the mixing block 49 to perform circular motion, thus agitating the material. The mixing process allows the raw materials to be better diluted and mixed, achieving good mixing quality. The rotation of the output shaft 43 also drives the automotive parts held by the limit clamp to rotate. At the same time, the water pump 7 can be started, allowing the water pump 7 to transport the mixed raw materials inside the partition box 401 to the inside of the output pipe 9 through the water pumping pipe 8. The materials are then transported through the output pipe 9 and sprayed out through the nozzle, uniformly spraying the automotive parts to achieve good spraying quality and eliminating any spraying dead corners. This facilitates further processing of the automotive parts and enhances the practicality of the device. During the spraying process, a certain amount of waste gas is generated. When it is necessary to discharge the waste gas, the exhaust fan 66 is started first. The exhaust fan 66 can draw the waste gas into the interior of the filter frame 61, and then filter and purify it through the sealing plate 64. This can block the harmful substances contained in the waste gas, so that the waste gas can be discharged after purification without affecting the surrounding environment, achieving a good working environment. In addition, when the purification plate 65 needs to be disassembled and replaced during long-term use, the sealing plate 64 is first pulled forward by the pull rod on the front of the sealing plate 64, so that the first magnetic block and the second magnetic block are released from the limit. At the same time, the sealing plate 64 will also drive the long block 63 to slide out from the interior of the fixing groove 62, thereby further realizing the removal of the purification plate 65 from the interior of the filter frame 61, realizing the disassembly of the purification plate 65, achieving good disassembly efficiency, and also facilitating the operation and use of the staff, enhancing the flexibility of the device.
