[0002] The anti-theft door is a special building door body. It uses special materials and structural design to enhance the anti-theft performance and prevent illegal intrusion. In the process of manufacturing anti-theft doors, spray painting on their surface is an important step, which can not only improve the texture of the door itself, but also increase the aesthetics of the anti-theft door.

[0003] The prior art discloses a paint spraying device for producing smart home anti-theft doors with application number: CN202222851278.2, which includes a body and a processing mechanism, wherein the processing mechanism is fixedly connected to the inside of the body, and the processing mechanism includes a spraying unit and a driving unit, wherein the spraying unit is fixedly connected to the top of the body, and the driving unit is rotatably connected to the inside of the body. The paint spraying device for producing smart home anti-theft doors wraps the spraying unit and the driving unit with a shell to prevent paint from scattering during spraying and preventing paint from falling to the ground with air, thereby reducing cleaning work and alleviating workload.

[0004] However, the spraying device has some defects and limitations. The spraying device can only simply spray paint on the surface of the security door, and cannot pre-clean the foreign particles adhered to the surface of the security door, which increases the roughness of the surface of the security door and reduces the spraying quality. In actual operation, the staff needs to manually clean the impurities before performing subsequent painting operations, which undoubtedly increases the complexity and labor intensity of the work; the existing spraying device can only paint one side of the security door. After one side is completed, the staff needs to manually lift and turn it over before painting the other side, which not only increases the difficulty of operation for the staff, but also easily causes the sprayed paint to splash onto the hands of the staff, affecting the spraying quality and the cleanliness of the surface of the security door; in addition, due to the need for manual turning, the efficiency of the painting operation is difficult to improve. In the case of mass production of security doors, this inefficient operation method will greatly slow down the production progress and reduce the processing efficiency of the product.

[0032] When spraying paint on the surface of the security door: first, place the security door to be painted between the movable plate 5 and the cross bar 8 above the U-shaped box 1, and make the clamping plates 9 on both sides contact the two ends of the security door, then turn the crank 7, the rotation of the crank 7 drives the screw rod 6 to rotate, the screw rod 6 is threadedly connected to the U-shaped frame 3, the screw rod 6 is driven to move on the U-shaped frame 3, and the movable plate 5 is pushed to slide inside the guide groove 4, so that the clamping plates 9 on one side of the movable plate 5 clamp the security door, at this time, the two clamping plates 9 clamp and fix the security door, increase the stability of the security door placed between the movable plate 5 and the cross bar 8, after the security door is clamped and fixed, by starting the hydraulic cylinder 24 in the mobile lifting assembly, the start of the hydraulic cylinder 24 drives the hydraulic rod 23 to retract, and the retraction of the hydraulic rod 23 drives the bracket 16 to descend, because the two ends of the U-shaped rod are fixedly connected to the brackets on both sides of the U-shaped box , so the bracket 16 descends and drives the U-shaped rod 38 installed thereon to rise and fall synchronously. When the U-shaped rod 38 descends, it drives the connecting rod 22 to descend. The two ends of the connecting rod 22 are respectively fixedly connected to the outer side walls of the dust hood 13 and the spray pipe 19, that is, the synchronous descent of the U-shaped rod 38 and the bracket 16 drives the cleaning roller 12 and the spray pipe 19 to descend synchronously. After the cleaning roller 12 contacts the anti-theft door, the hydraulic cylinder 24 is stopped at this time; after the hydraulic cylinder 24 is stopped, the drive assembly is started to drive the screw 28 to rotate, and the rotation of the screw 28 drives the nut 27 inside the slide rail 26 to move inside it. The movement of the nut 27 drives the box body 25 fixedly connected on one side to move synchronously, and the movement of the box body 25 drives the hydraulic cylinder 24 to move. The hydraulic cylinder 24 drives the bracket 16 to move through the hydraulic rod 23. The movement of the bracket 16 can drive the cleaning roller 12 and the spray pipe 19 to move above the anti-theft door.

[0033] When the cleaning roller 12 moves above the security door, the gears 17 at both ends of the cleaning roller 12 are meshed with the toothed plates 18 on the U-shaped box 1, driving the cleaning roller 12 to rotate. The cleaning roller 12 rotates to clean the dust and foreign particles on the surface of the security door. The dust on the surface of the security door cleaned and raised by the cleaning roller 12 will be sucked into the collecting box 15 by the fan 36. The fan 36 starts to suck the air in the dust hood 13, so that negative pressure is generated in the dust hood 13. At this time, the raised dust and particles in the cleaning area will be sucked into the dust suction pipe 14, and then enter the collecting box 15 through the dust suction pipe 14, so as to remove the dust and foreign particles on the surface of the security door, and avoid the dust and foreign particles adhering to the surface of the security door and affecting the surface painting of the security door. This method has the effect of cleaning the surface of the security door and increases the firmness and aesthetics of the paint sprayed on the surface of the security door.

[0034] When the cleaning roller 12 is cleaning the surface of the security door, the paint pump 37 on the hose 21 is started. The paint in the U-box 1 is transported to the spray pipe 19 through the hose 21, and then sprayed out by the nozzle 20 on one side of the spray pipe 19, so that the surface of the security door can be sprayed with paint, and mobile spraying is realized at the same time, making it convenient to spray paint on the surface of the security door.

[0035] After the painting of one side of the security door is completed, the hydraulic cylinder 24 in the mobile lifting assembly is started to drive the bracket 16 to rise, so that the cleaning roller 12 and the spray pipe 19 are separated from the security door, and then the first motor 10 is started to rotate the first motor 10 to drive the drive shaft 11 to rotate, and the drive shaft 11 rotates to drive the output clamping plate 9 to rotate, so that the clamped and fixed security door can be rotated and turned over. After the security door is turned over, the third motor 39 on the U-shaped rod 38 is started again, and the third motor 39 starts to drive the connecting rod 22 at the output end to rotate. The rotation of the connecting rod 22 drives the spray pipe 19 and the dust hood 13 fixedly connected at its ends to rotate synchronously, so that the spray pipe 19 and the dust hood 13 rotate, and rotate 180 degrees to make the cleaning roller 12 and the spray pipe 19 and the dust hood 13 rotate. 19 changes its position, after the position between the cleaning roller 12 and the spraying tube 19 changes, the hydraulic cylinder 24 is lowered to make the cleaning roller 12 contact with the anti-theft door, and then the second motor 32 is started, and similarly the cleaning roller 12 is moved on the surface of the anti-theft door for cleaning, and the cleaning roller 12 and the spraying tube 19 are moved in opposite directions. At this time, the flipped side is cleaned and painted, which increases the convenience of flipping, cleaning and painting the anti-theft door, and at the same time, the cleaning roller 12 and the spraying tube 19 are moved back and forth once above the U-shaped box 1, and the double sides of the anti-theft door are cleaned and painted, which effectively reduces the labor intensity of the staff, improves the convenience of flipping the anti-theft door, and effectively improves the work efficiency of the anti-theft door surface spraying and the quality of its surface spraying.

[0038] In this embodiment, a driving assembly is provided at the end of the screw 28. When the second motor 32 is started, the screws 28 on both sides of the U-shaped box 1 are driven to rotate synchronously, thereby avoiding the use of multiple driving motors to drive the screw 28. When in use, the second motor 32 is started, and the second motor 32 starts to drive the shaft 31 at the output end to rotate. The rotation of the shaft 31 drives the worm 29 fixedly sleeved on its surface to rotate synchronously. Due to the meshing connection between the worm 29 and the worm wheel 30, the worm wheel 30 is driven to rotate when the worm 29 rotates.
