Description

Technical Field

[0001] This utility model relates to the field of degreasing technology for electrophoretic components, and in particular to a spray device for degreasing electrophoretic components. Background Technology

[0002] Degreasing is a pretreatment process for metal parts processing and coating. Because oil stains will adhere to the surface of metal parts during processing, it is necessary to clean them before electrophoresis to remove the oil stains from the surface of the metal parts and increase the adhesion of the coating. A spray device is used to spray degreasing treatment on the electrophoretic parts.

[0003] Chinese patent application publication number CN219951225U discloses a spray system for degreasing electrophoretic parts, including a spray chamber and a conveyor chain. The workpiece is hung on the conveyor chain by a hanger and is conveyed from one end of the spray chamber to the other end of the spray chamber. Several pairs of spray nozzles for spraying the conveyed workpiece are installed on the inner walls on both sides of the spray chamber. The system includes a rotating device and a driving mechanism. The rotating device is installed on the conveyor chain and includes a rotating component that is driven to rotate by the driving mechanism. The rotating component is equipped with a hanging mechanism that cooperates with the hanger.

[0004] Although the above-mentioned device can perform spray degreasing treatment on electrophoretic parts, the degreasing liquid will flow directly out of the spray chamber after spraying the electrophoretic parts, which easily leads to waste of the degreasing liquid. The waste of degreasing liquid increases production costs. Therefore, this utility model provides a spray device for degreasing electrophoretic parts. Utility Model Content

A first bevel gear is fixedly installed on the surface of the rotating shaft. A second bevel gear is meshed on the surface of the first bevel gear. A screw is fixedly installed inside the second bevel gear. The screw is rotatably connected to the spray tank. The screw is threadedly connected to a movable frame. A fixed frame is rotatably connected to the surface of the screw. The fixed frame is fixedly connected to the spray tank. The movable frame is slidably connected to the fixed frame.

[0011] Preferably, a pool door is provided on the front side of the spray pool, and a handle is fixedly installed on the front side of the pool door.

[0012] Preferably, an inlet pipe and an outlet pipe are fixedly installed on the front side of the spray tank, and control valves are respectively installed on the inlet pipe and the outlet pipe.

[0013] Preferably, the screw is a bidirectional threaded screw, and the screw is made of stainless steel.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In the process of spraying and degreasing the electrophoretic parts, the waste degreasing liquid after spraying falls into the guide plate and flows along the guide plate into the middle of the filter assembly.

The filter assembly includes a mesh frame 9 installed inside the spray tank 1, and a filter screen 10 fixedly installed on the top of the mesh frame 9, which facilitates multiple filtrations of the degreasing liquid, ensuring that the degreasing liquid flowing back to the bottom of the spray tank 1 is basically clean, thereby reducing the frequency of degreasing liquid replacement and reducing costs. A drive assembly is located on the left side of the spray tank 1, and the spray tank 1 is equipped with a drive assembly. The device is equipped with a movable frame 18, with a cleaning brush 19 fixedly installed at the bottom of the movable frame 18. During the degreasing process of the electrophoretic parts, the waste degreasing liquid after spraying falls into the guide plate 8 and flows along the guide plate 8 into the middle of the filter assembly. After being filtered multiple times by the filter assembly, it flows back to the bottom of the spray tank 1, realizing the recycling of the degreasing liquid, reducing the waste of degreasing liquid, and significantly reducing production costs. In addition, the movable frame 18 and the cleaning brush 19 are driven by the drive assembly to move left and right, which can clean the impurities in the middle of the filter assembly, prevent the impurities from clogging the middle of the filter assembly, maintain the permeability of the middle of the filter assembly, and improve the filtration speed.

[0023] Specifically, the spray assembly includes a delivery pump 4 installed inside the spray tank 1. A connecting pipe 5 is fixedly installed at the output end of the delivery pump 4. The connecting pipe 5 is fixedly connected to both the spray tank 1 and the spray chamber 2. A diversion pipe 6 is fixedly installed at the liquid outlet end of the connecting pipe 5. The diversion pipe 6 is located inside the spray chamber 2. A nozzle 7 is fixedly installed on the opposite side of the diversion pipe 6, which can deliver the degreasing liquid in the spray tank 1 to the electrophoresis piece, thereby facilitating the spray degreasing of the electrophoresis piece.

[0024] Specifically, the drive assembly includes a fixed plate 11 located on the left side of the spray tank 1. A drive motor 12 is fixedly installed at the bottom of the fixed plate 11. The output end of the drive motor 12 extends through the fixed plate 11 to the top of the fixed plate 11 and is fixedly installed with a rotating shaft 13. A first bevel gear 14 is fixedly installed on the surface of the rotating shaft 13. A second bevel gear 15 is meshed on the surface of the first bevel gear 14. A screw 16 is fixedly installed inside the second bevel gear 15. The screw 16 is a bidirectional threaded rod made of stainless steel. The screw 16 is rotatably connected to the spray tank 1 and threadedly connected to the movable frame 18. A fixed frame 17 is rotatably connected to the surface of the screw 16 and is fixedly connected to the spray tank 1. The movable frame 18 is slidably connected to the fixed frame 17. The drive assembly facilitates the left and right movement of the movable frame 18, thereby facilitating the left and right movement of the cleaning brush 19 and cleaning the middle part of the filter screen 10, ensuring the permeability of the middle part of the filter screen 10.

[0025] Specifically, a pool door 20 is provided on the front side of the spray tank 1, and a handle 21 is fixedly installed on the front side of the pool door 20. By opening the pool door 20 through the handle 21, impurities on the mesh frame 9 can be cleaned and the filter screen 10 can be maintained. An inlet pipe 22 and an outlet pipe 23 are fixedly installed on the front side of the spray tank 1. Control valves are respectively provided on the inlet pipe 22 and the outlet pipe 23. Opening the control valve on the outlet pipe 23 facilitates the discharge of degreasing liquid in the spray tank 1. After discharge, the control valve on the outlet pipe 23 is closed and the control valve on the inlet pipe 22 is opened to facilitate the addition of degreasing liquid to the spray tank 1 and facilitate the replacement of degreasing liquid.

[0026] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.

[0027] In use: During the suspension transport of the electrophoretic parts by the suspended conveyor chain 3, the electrophoretic parts will pass through the spray chamber 2. At the same time, the degreasing liquid in the spray tank 1 can be transported to the connecting pipe 5 by the delivery pump 4, and then enters the diversion pipe 6 for diversion. Finally, it is sprayed out from the nozzle 7, thereby spraying and degreasing the electrophoretic parts. The degreasing waste liquid after spraying will fall into the guide plate 8, and fall along the guide plate 8 into the middle of the filter screen 10. After being filtered by multiple filter screens 10, it flows back to the bottom of the spray tank 1. At the same time, the drive motor 12 causes the rotating shaft 13 to rotate, which causes the first bevel gear 14 to rotate, the second bevel gear 15 to rotate, and the screw 16 to rotate. This causes the moving frame 18 to move left and right along the fixed frame 17, and the cleaning brush 19 to move left and right, which can clean the impurities on the filter screen 10 into the screen frame 9.
