Description

Technical Field

[0001] This utility model relates to the field of rust prevention for automotive parts, and in particular to a rust prevention spraying device for automotive parts. Background Technology

[0002] In the modern automotive manufacturing industry, ensuring the quality and performance of automotive parts is of paramount importance, and rust prevention, as a key step, directly affects the durability and reliability of parts during storage, transportation, and subsequent assembly and use.

[0003] Most existing rust-preventive spraying devices place parts on a fixed conveyor, with nozzles spraying rust-preventive liquid from a fixed position. Since the parts cannot be flipped over, only the upward-facing side or a few exposed surfaces can be effectively sprayed during the spraying process. The downward-facing or obscured surfaces are difficult to be fully covered by the rust-preventive liquid. No matter how much conventional methods such as optimizing the nozzle layout, angle, and flow control are used, as long as the parts cannot be flipped over, a large number of surface areas will always be unable to receive uniform and sufficient rust-preventive liquid spraying. This inevitably leads to the formation of rust hazards in these improperly treated areas, seriously restricting the overall rust prevention quality and failing to achieve the goal of all-round protection for the parts. We propose a rust-preventive spraying device for automotive parts. Summary of the Invention

[0004] The main objective of this invention is to provide a rust-preventive spraying device for automotive parts, which can effectively solve the problems in the background art.

[0013] Preferably, the spray box has multiple filter holes on one side, and all of the filter holes are located inside the liquid storage tank.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This rust-preventing spraying device for automotive parts uses a drive motor to rotate a third rotating wheel. Through a second belt, a fourth rotating wheel drives a second active roller.

[0026] In this embodiment, the transmission component includes a drive motor 9. A mounting block 10 is fixedly connected to the upper end of the drive motor 9. The drive motor 9 is fixedly installed on one side of the spray box 1 through the mounting block 10. A third moving wheel 17 is fixedly connected to the outer side of the output end of the drive motor 9. The third moving wheel 17 is located on the outer side of the spray box 1.

[0027] Specifically, by starting the drive motor 9, the output of the drive motor 9 will drive the third drive wheel 17 to rotate. At this time, through the transmission of the second belt 18, the fourth drive wheel 19 can be easily driven to rotate the second drive roller 20. With the cooperation of the second driven roller 22, the second conveyor belt 21 can be easily driven to move the car parts into the inner cavity of the spray box 1.

[0028] In this embodiment, a first moving wheel 11 is fixedly connected to the outer side of the output end of the drive motor 9. The first moving wheel 11 is located on one side of the third moving wheel 17. A first belt 12 is sleeved on the outer side of the first moving wheel 11. A second moving wheel 13 is sleeved on the inner side of the other section of the first belt 12. A first driving roller 14 is fixedly connected to the inner side of the second moving wheel 13. The first driving roller 14 is rotatably connected to the spray box 1. A first driven roller 16 is rotatably connected to the inner wall of the spray box 1. A first conveyor belt 15 is rotatably connected to the outer side of the first driven roller 16.

[0029] Specifically, while the output of the drive motor 9 is rotating, it will also drive the first moving wheel 11 to rotate. The rotation of the first moving wheel 11 will drive the first belt 12 to rotate, which in turn will enable the second moving wheel 13 to drive the first driving roller 14 to rotate. At this time, through the transmission cooperation of the first driven roller 16, the first conveyor belt 15 can easily drive the flipped car parts to continue to move.

[0030] In this embodiment, the output end of the drive motor 9 is fixedly connected to a rotating shaft 23, which is rotatably connected to the spray box 1. Four material-turning plates 24 are fixedly connected to the outside of the rotating shaft 23, and the four material-turning plates 24 are all located in the inner cavity of the spray box 1.

[0036] It should be noted that this utility model is a rust-preventive spraying device for automotive parts. The user first injects the rust-preventive liquid into the storage tank 4, then places the automotive parts requiring rust prevention onto the upper end of the second conveyor belt 21 through the inlet 2.

At this time, pressure pump 8 is activated, injecting rust inhibitor from storage tank 4 into the inner cavity of branch pipe 6 through connecting pipe 5. The rust inhibitor is then sprayed out through multiple spray nozzles 7, treating one side of the automotive parts at the upper end of the second conveyor belt 21 with rust inhibitor. The sprayed rust inhibitor flows downwards on the surface of the automotive parts, and through the round holes at the upper end of the second conveyor belt 21, it flows into the lower end of the inner cavity of spray box 1, and then through the spray box... The filter holes 25 on one side flow back into the inner cavity of the liquid storage tank 4, thereby collecting and reusing excess rust inhibitor, effectively saving the cost of rust inhibitor usage. Simultaneously with the start of the drive motor 9, the output of the drive motor 9 also drives the rotating shaft 23 to rotate. The rotation of the rotating shaft 23 drives the four flipping plates 24 to rotate, facilitating the flipping of automotive parts. Simultaneously with the rotation of the output of the drive motor 9, the first moving wheel 11 also rotates, which in turn drives the first belt 12 to rotate. This allows the second moving wheel 13 to drive the first active roller 14 to rotate. Through the transmission of the first driven roller 16, the first conveyor belt 15 can easily move the flipped automotive parts. The rust inhibitor sprayed from multiple spray nozzles 7 then provides rust prevention treatment to the flipped automotive parts, ensuring a comprehensive and uniform rust inhibitor spraying effect during rust prevention treatment, effectively avoiding spray dead zones, making it quite practical.
