Description

Technical Field

[0001] This utility model relates to the field of metal sheet spraying technology, specifically to a dustproof spraying device for metal sheets. Background Technology

[0002] Metal sheets play a crucial role in industrial production, and their surface quality directly affects the final performance and appearance of the product. To improve the corrosion resistance and service life of metal sheets, high-temperature resistant and rust-proof coatings are typically applied to their surfaces using spraying technology.

[0003] Chinese patented invention CN218655070U discloses a spraying device for a high-temperature resistant and rust-proof coating on metal. The device includes a transverse moving frame. Support rods are fixedly installed on the left and right sides of the lower outer surface of the transverse moving frame. A front-rear moving frame is provided on the lower outer surface of the support rods. A mounting plate is fixedly installed on one side of the outer surface of the front-rear moving frame. There are two sets of the front-rear moving frames, mounting plates, and support rods. A movable mounting frame is connected to one side of the outer surface of the transverse moving frame. A mounting rod is fixedly installed on the lower outer surface of the movable mounting frame. A drag chain is provided on the upper outer surface of the movable mounting frame. An electric telescopic rod is fixedly installed on the upper outer surface of the mounting rod. A spray head is fixedly installed on the lower outer surface of the electric telescopic rod. This invention provides a spraying device for a high-temperature resistant and rust-proof coating on metal, which offers advantages such as easy spraying of large metal plates, easy adjustment of the spray head height, and easy loading and unloading of materials.

[0004] However, the device still has some problems. In actual use, when metal sheets are sprayed, they are often directly exposed to an open environment. In this environment, dust, particles and other impurities in the air are very easy to adhere to the surface of the metal sheet. These impurities not only affect the uniformity and adhesion of the coating, but may also lead to poor interfacial bonding between the coating and the metal sheet, thereby weakening the coating's rust prevention and high temperature resistance. Therefore, we propose a dustproof spraying equipment for metal sheets to solve the above problems. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a dustproof spraying equipment for metal sheets, which has the following beneficial effects:

[0017] This invention utilizes a first motor that rotates forward, driving a screw to move a movable plate. The movable plate, via a U-shaped plate, moves a sealing plate, causing the U-shaped plate to move out of the transparent box. A metal plate is then placed on the U-shaped plate. An electric push rod is then activated, moving a corresponding clamping plate to secure the metal plate. After securing, the first motor is restarted in the reverse direction, again driving the movable plate via a screw. The movable plate, via the clamping plates on the U-shaped plate, moves the metal plate into the transparent box, where it is sealed to prevent dust from entering. Finally, a spray nozzle reciprocates to spray the metal plate. This process effectively prevents dust and other impurities from contaminating the metal surface, ensuring high-quality and efficient spraying operations. Attached Figure Description

A first motor 5 is fixedly connected to the rear side of the transparent box 1. The end of the screw 3 extends to the rear side of the transparent box 1 and is fixedly connected to the output shaft of the first motor 5. A U-shaped plate 6 is welded to the top of the movable plate 4. An electric push rod 7 is fixedly connected to one inner wall of the U-shaped plate 6. A clamping plate 8 is fixedly connected to the output end of the electric push rod 7. A rectangular hole 14 is formed on the front inner wall of the transparent box 1. A sealing plate 9 is movably contacted on the rectangular hole 14. The rear side of the sealing plate 9 is fixedly connected to the front side of the U-shaped plate 6. Multiple spray nozzles 10 are provided above the U-shaped plate 6. Two limiting rods 11 are fixedly connected to the inner walls of both sides of the U-shaped plate 6. A connecting rod 12 is slidably connected to rod 11. The end of the connecting rod 12 is fixedly connected to one side of the corresponding clamping plate 8. When the first motor 5 is started, it rotates in the forward direction and drives the moving plate 4 to move through the screw 3. The moving plate 4 drives the sealing plate 9 to move through the U-shaped plate 6, so that the U-shaped plate 6 moves out of the transparent box 1 and the metal plate is placed on the U-shaped plate 6. The electric push rod 7 is started and drives the corresponding clamping plate 8 to move. The metal plate is fixed by the two clamping plates 8. After fixing, the first motor 5 is started to rotate in the reverse direction. The first motor 5 drives the moving plate 4 to move through the screw 3. The moving plate 4 drives the metal plate to move into the transparent box 1 through the clamping plate 8 on the U-shaped plate 6. The sealing plate 9 seals the metal plate to prevent dust from entering. Then, the spray nozzle 10 moves back and forth to spray the metal plate. This can effectively prevent dust and other impurities from contaminating the surface of the metal plate and ensure the high quality and high efficiency of the spraying operation.

[0027] In some embodiments, two square rods 13 are welded between the inner walls of the two sides of the groove 2. The square rods 13 are slidably connected to the movable plate 4. The square rods 13 serve a positioning function.

[0028] In some embodiments, a reciprocating lead screw 15 is rotatably connected between the inner walls of the two sides of the transparent box 1, and a second motor 16 is fixedly connected to the left side of the transparent box 1. The end of the reciprocating lead screw 15 extends to the outside of the transparent box 1 and is fixedly connected to the output shaft of the second motor 16.

[0029] In some embodiments, a rectangular plate 17 is threaded onto the reciprocating lead screw 15, and two support columns 18 are welded to the bottom of the rectangular plate 17. The support columns 18 serve as a connection.

[0031] In some embodiments, two crossbars 21 are welded between the inner walls of the two sides of the transparent box 1. The crossbars 21 are slidably connected to the rectangular plate 17. Four cylinders 22 are welded to the bottom of the transparent box 1. The ends of two cylinders 22 on the same side are fixedly connected to the same support plate 23. The support plate 23 serves to provide support.

[0032] The working principle or structural principle is as follows: When in use, the first motor 5 is started and rotates forward. The first motor 5 drives the screw 3 to rotate, and the screw 3 drives the moving plate 4 to slide on the square rod 13. The moving plate 4 drives the U-shaped plate 6 to move, and the U-shaped plate 6 drives the sealing plate 9 to move, causing the U-shaped plate 6 to move out of the transparent box 1. Then, the metal plate is placed on the U-shaped plate 6, and the electric push rod 7 is started. The electric push rod 7 drives the corresponding clamping plate 8 to move, fixing the metal plate through the two clamping plates 8. The clamping plates 8 drive the corresponding connecting rod 12 to the limiting rod 11. After fixing, the first motor 5 is started again in reverse. Rotating, the first motor 5 drives the moving plate 4 to move via the screw 3. The moving plate 4, via the clamping plate 8 on the U-shaped plate 6, moves the metal plate into the transparent box 1, where it is sealed by the sealing plate 9 to prevent dust from entering. Then, the second motor 16 is started. The second motor 16 drives the rectangular plate 17 to move via the reciprocating screw 15 and slide on the crossbar 21. The rectangular plate 17, via the support column 18, drives the nozzle 10 on the rectangular tube 19 to move back and forth to spray the metal plate. This effectively prevents dust and other impurities from contaminating the surface of the metal plate, ensuring high quality and high efficiency in the spraying operation.
