Description

Technical Field

[0001] This utility model belongs to the field of die casting technology, and in particular relates to an anti-corrosion spraying device for alloy surfaces. Background Technology

[0002] The purpose of anti-corrosion spraying on alloy surfaces is to provide customized protection for the characteristics of alloy materials, significantly extending their service life and maintaining performance stability, such as active metal components, easy oxidation, and complex microstructure.

[0003] Chinese utility model patent CN215744314U discloses a surface anti-corrosion spraying device for alloy die-cast products. The device utilizes a first sliding groove and a first sliding block to facilitate user positioning of the clamping plate and aid in its movement. A second sliding groove and a second sliding block facilitate user positioning of the third threaded sleeve, improving its stability. A protective frame enhances the protection of the second motor. A combination of a heat dissipation groove, a locking block, a baffle, and a pull ring allows the user to enhance heat dissipation when the internal temperature of the machine is too high after drying. The fasteners improve the stability of the water inlet pipe. A filter screen filters out dripping anti-corrosion coating and removes impurities.

[0004] However, when the device sprays the alloy surface, it sprays both the top and bottom surfaces. Since the alloy surface generally needs to be sprayed, spraying only the top and bottom surfaces can easily lead to incomplete spraying, requiring a second spraying, which affects the overall spraying efficiency of the device. Utility Model Content

[0005] The purpose of this invention is to provide an anti-corrosion spraying device for alloy surfaces. This anti-corrosion spraying device can completely coat alloy surfaces.

[0006] The technical solution adopted by this utility model to solve the above problems is: an alloy surface anti-corrosion spraying device, comprising:

[0007] A liquid storage tank, wherein a support bar is fixedly connected to the top of the liquid storage tank, and a top plate is fixedly connected to the top of the support bar;

[0008] Two sets of rotating components are provided, one on each side of the alloy. The rotating components include a fixed toothed plate on the top of the liquid storage tank, a rotating gear meshing with the fixed toothed plate, a sleeve fixedly connected to the shaft of the rotating gear, a piston rod slidably connected inside the sleeve, a threaded rod threadedly connected inside the piston rod, one end of the threaded rod rotatably connected to the inner wall of the sleeve, a first helical gear sleeved on the threaded rod, and a second helical gear meshing with the first helical gear.

[0021] In summary, this utility model has the following advantages:

[0022] 1. This utility model, by setting up a rotating assembly, places the alloy between two piston rods. Rotating the intermediate shaft of the two second helical gears causes the second helical gear to rotate, which in turn causes the threaded rod to move along the sleeve with the piston rod until the two piston rods clamp and fix the alloy. Then, the drive motor is started, causing the lead screw to rotate, which in turn moves the limiting component, causing the two connecting plates and the screen plate to move with the alloy. During this process, the rotating gear is acted upon by the fixed gear plate, causing the rotating gear to rotate, which in turn rotates the sleeve, causing the two piston rods to rotate with the alloy. This allows the coating liquid to be sprayed evenly onto the alloy surface, while the drying distribution pipe evenly dries the alloy surface, resulting in more comprehensive coating and improved overall working efficiency.

[0023] 2. This utility model, by setting up a spraying and drying assembly, starts a pump to transport the coating liquid through a connecting pipe to the inside of a first flexible tube and then to a spraying distribution pipe for spraying the alloy surface. At the same time, a fan is started to transport airflow through the first flexible tube to the drying distribution pipe for drying the alloy surface. During this process, the dripping coating liquid passes through a screen plate and a filter plate, and impurities in the coating liquid are filtered out and returned to the inside of the storage tank for recycling, thus saving coating liquid resources.

A handwheel is fixedly connected to one end of the intermediate shaft of the second diversion pipe helical gear 10 for easy rotation of the second helical gear 10. A connecting plate 11 is installed on the outer side of the sleeve 6, and a rotating bearing is installed on the outer side of the sleeve 6. The rotating bearing is installed inside the connecting plate 11 to facilitate the rotation of the sleeve 6. A horizontal plate 12 is fixedly connected to the top of the connecting plate 11, and a spray drying assembly is installed on the top of the horizontal plate 12. A screen plate 13 is fixedly connected between the two connecting plates 11. A limiting member 14 is fixedly connected to the surface of the connecting plate 11. A limiting groove is opened on the surface of the fixed toothed plate 4. The limiting member 14 is slidably set inside the limiting groove to ensure the normal operation of the limiting member 14. A lead screw 15 is threadedly connected inside the back limiting member 14. A drive motor is fixedly connected to the right end of the lead screw 15. The left end of the lead screw 15 is rotatably connected to the surface of the left back support bar 2. A guide rod is slidably set through the inside of the front limiting member 14. The two ends of the guide rod are rotatably connected to the surfaces of the two front support bars 2 respectively.

[0034] The spraying and drying assembly is used for spraying and drying alloy surfaces. The assembly includes a spraying manifold 16 and a drying manifold 24. Nozzles are evenly spaced along the surface of the spraying manifold 16, and air outlets are evenly spaced along the surface of the drying manifold 24. Vertical plates 17 are fixedly connected to the front and back of both the spraying manifold 16 and the drying manifold 24. The bottom of the vertical plates 17 is fixedly connected to the top of the horizontal plate 12. A first flexible hose 18 is connected to the top of the spraying manifold 16, and a pump 19 is connected to one end of the first flexible hose 18. A support base is installed at the bottom of the pump 19, and the bottom of the support base is fixedly connected to the top of the top plate 3, ensuring the normal operation of the pump 19. A connecting pipe 20 is connected to the input end of the pump 19. Two limiting blocks are fitted onto the surface of the connecting pipe 20. The surfaces of the two limiting blocks are fixedly connected to the front of the top plate 3 and the front of the liquid storage tank 1, respectively, to ensure the normal operation of the connecting pipe 20. One end of the connecting pipe 20 is connected to the front of the liquid storage tank 1. The top of the drying diversion pipe 24 is connected to the second flexible hose 21. A straight groove is opened on the surface of the top plate 3.

[0035] The implementation principle of the alloy surface anti-corrosion spraying device in this embodiment is as follows: the pump 19 is started, so that the coating liquid is transported through the connecting pipe 20 to the inside of the first hose 18 and then to the spraying diversion pipe 16 to spray the alloy surface. At the same time, the fan 22 is started, so that the airflow is transported through the first hose 18 to the drying diversion pipe 24 to dry the alloy surface. During this process, the dripping coating liquid will pass through the screen plate 13 and the filter plate, and the impurities in the coating liquid will be filtered out and returned to the inside of the storage tank 1 for recycling, thus saving coating liquid resources.

[0036] The alloy is placed between the two piston rods 7. The intermediate shaft of the two second helical gears 10 is rotated, causing the second helical gears 10 to rotate along the first helical gear 9. This causes the threaded rod 8 to move along the sleeve 6 with the piston rods 7 until the two piston rods 7 clamp and fix the alloy. Then, the drive motor is started, causing the lead screw 15 to rotate, which in turn causes the limiting member 14 to move. This causes the two connecting plates 11 and the screen plate 13 to move with the alloy. During this process, the rotating gear 5 is acted upon by the fixed toothed plate 4, causing the rotating gear 5 to rotate, which in turn causes the sleeve 6 to rotate. This causes the two piston rods 7 to rotate with the alloy, allowing the coating liquid to be sprayed evenly onto the alloy surface. At the same time, the drying diversion pipe 24 can evenly dry the alloy surface, making the coating more comprehensive and improving the overall working efficiency of the device.
