[0002] Civil air defense equipment door leaves refer to protective door leaves used in civil air defense projects. They are designed and manufactured to provide protection for personnel and materials sheltering, command, medical rescue, etc. during wartime. Civil air defense equipment door leaves are usually sprayed on the surface through a spray device during production to improve their aesthetics and corrosion resistance. However, the existing civil air defense equipment door leaf spray device has difficulty adjusting the angle of the nozzle during the painting process, making the spraying direction relatively single.

[0003] In order to address the above problems, a Chinese patent with the existing announcement number CN220126660U proposes a door leaf spray device for civil air defense equipment. The device drives the linkage rod to move up and down through a cylinder. Since a placement plate is fixed on the linkage rod and a ball is fixed on the placement plate, when the placement plate moves up and down, the ball also moves with the movement of the placement plate. The ball is set with a spray gun so that the paint can automatically adjust the up and down position during the operation of the equipment. The setting of the ball is to enable the spray gun to adjust the position at multiple angles, so that the equipment can spray paint at a wider range of angles.

[0004] However, although the above-mentioned door leaf spray device of civil air defense equipment can adjust the paint spraying angle of the spray gun through the ball and the cylinder, thereby improving the application range of the device, during the use of the spray gun of the door leaf spray device of civil air defense equipment, the ball is prone to loosening and the adjustment process is relatively cumbersome, resulting in the problem of reduced spraying efficiency of the door leaf of civil air defense equipment.

[0032] like Figures 1 to 5As shown, an embodiment of the utility model provides a door leaf spraying device for civil air defense equipment, including a conveyor belt mechanism 1, on which a plurality of door leaf fixing mechanisms 2 for fixing the door leaves of the civil air defense equipment are provided, a device body 3, which is arranged on one side of the conveyor belt mechanism 1, and an opening is penetrated through the device body 3 directly opposite the door leaf fixing mechanism 2, a conveying pipe 5 is rotatably connected in the device body 3, and the conveying pipe 5 is connected to a nozzle 6 toward the opening, the first end of the conveying pipe 5 is connected to the outlet of the spray pump 10 through a connecting pipe, and the inlet of the spray pump 10 is connected to a paint tank 8, a driving component 4 for driving the conveying pipe 5 to reciprocate is provided on the device body 3, and a controller 16 is arranged on the device body 3, and the controller 16 is connected to the driving component 4 and the spray pump 10 by signal.

[0033] Specifically, the door leaf of the civil air defense equipment is fixed by the door leaf fixing mechanism 2, and then the door leaf fixing mechanism 2 is moved to the opening of the device body 3 by controlling the conveyor belt mechanism 1. At this time, the door leaf of the civil air defense equipment on the door leaf fixing mechanism 2 is facing the opening, and then the spray pump 10 is controlled by the controller 16 to transport the liquid in the paint tank 8 to the conveying pipe 5, and then the liquid is sprayed onto the door leaf of the civil air defense equipment by the nozzle 6. At the same time, the controller 16 will drive the driving component 4 to drive the conveying pipe 5 to rotate back and forth, thereby improving the spraying effect on the door leaf of the civil air defense equipment and avoiding the loosening of the nozzle 6. This solves the problem that the ball bearing of the spray gun of the existing door leaf spraying device of civil air defense equipment is easy to loosen during use and the adjustment process is relatively cumbersome, thereby reducing the spraying efficiency of the door leaf of the civil air defense equipment.

[0034] It should be noted that the controller 16 can control the mutual operation between the drive component 4, the spray pump 10 and the conveyor belt mechanism 1, that is, when the conveyor belt mechanism 1 moves the door leaf of the civil air defense equipment to the opening facing the device body 3 (which can be achieved by installing sensors and other structures, which is the prior art), the controller 16 stops the operation of the conveyor belt mechanism 1 and turns to start the spray pump 10 and the drive component 4, so that the shower head can spray the door leaf of the civil air defense equipment. At the same time, in this embodiment, the connection of the lines between the controller 16, the drive component 4 and the spray pump 10 is also the prior art.

[0035] like Figure 4 and Figure 5As shown, in this embodiment, the driving assembly 4 includes a rotating shaft 42, which is rotatably arranged on the device body 3, and a half gear 43 is sleeved on the rotating shaft 42. The rotating shaft 42 is driven by a motor 41, a first gear 44 is sleeved on the second end of the conveying pipe 5, and the first gear 44 is meshed with the half gear 43. A torsion spring 45 is sleeved on the conveying pipe 5, and the two ends of the torsion spring 45 are respectively fixedly connected to the device body 3 and the conveying pipe 5. The inner wall of the device body 3 is fixedly connected to an infrared sensor 15, and the infrared sensor 15 is connected to the controller 16 for signal communication. Then, the device body 3 is rotatably connected with a rotating shaft 2 9, the rotating shaft 2 9 is sleeved with a second gear 11 that can mesh with the half gear 43, the second gear 11 and the first gear 44 are arranged opposite to each other along the half gear 43, the rotating shaft 2 9 is sleeved with a bevel gear 12, and the driving shaft 14 of the conveyor belt mechanism 1 is sleeved with a bevel gear 2 13 that meshes with the bevel gear 12. Specifically, the rotating shaft 1 42 is driven to rotate by the motor 41, and the rotating shaft 1 42 drives the half gear 43 to rotate. The half gear 43 first drives the first gear 44 to rotate, and the first gear 44 drives the conveying pipeline 5 The first gear 44 rotates to realize the rotation of the spray head 6. When the half gear 43 is disengaged from the first gear 44, the conveying pipe 5 is reset under the action of the torsion spring 45. At this time, the spraying work of the door leaf of the civil air defense equipment on the conveyor belt mechanism 1 is completed. At the same time, the motor 41 drives the half gear 43 to continue to rotate and drives the second gear 11 to rotate. The second gear 11 drives the rotating shaft 2 9 to rotate, thereby driving the bevel gear 1 12 to rotate. The bevel gear 1 12 drives the bevel gear 2 13 to rotate, so that the conveyor belt mechanism 1 rotates and drives the next door leaf fixing mechanism 2 to move to the opening of the device body 3. At this time, the half gear 43 disengages from the second gear 11 and meshes with the first gear 44, thereby continuing the spraying work. During the whole process, there is no need to manually control the opening and closing of the spraying work, because the infrared sensor will send a signal to the controller 16 when the spraying work of the nozzle 6 is completed, so that the controller 16 stops the operation of the spray pump 10, and then restarts the spray pump 10 after an interval of a few seconds. The interval time is the time it takes for the door leaf fixing mechanism 2 to move to the opening of the device body 3; it should be noted that the motor 41 can be a three-phase motor, a reduction motor, etc.

[0036] like Figure 4 As shown, in this embodiment, the infrared sensor 15 is flush with the lowest position of the nozzle 6 when it reciprocates, and can sense the nozzle 6.

[0037] like Figure 2 As shown, in this embodiment, the diameter of bevel gear 12 is greater than the diameter of bevel gear 2 13 . Specifically, bevel gear 12 can accelerate the rotation of bevel gear 2 13 , thereby improving the transmission efficiency of the conveyor belt mechanism 1 .

[0038] like Figure 4 As shown, in this embodiment, there are multiple nozzles 6.

[0039] Working principle:

[0040] The door leaf of the civil air defense equipment is fixed by the door leaf fixing mechanism 2, and then the door leaf fixing mechanism 2 is moved to the opening of the device body 3 by controlling the conveyor belt mechanism 1. At this time, the door leaf of the civil air defense equipment on the door leaf fixing mechanism 2 is facing the opening, and then the spray pump 10 is controlled by the controller 16 to transport the liquid in the paint spray box 8 to the conveying pipe 5, and then the liquid is sprayed to the door leaf of the civil air defense equipment by the nozzle 6. The motor 41 is controlled by the controller 16 to drive the rotating shaft 1 42 to rotate, and the rotating shaft 1 42 drives the half gear 43 to rotate. The half gear 43 first drives the first gear 44 to rotate, and the first gear 44 drives the conveying pipe 5 to rotate, that is, the rotation of the nozzle 6 is realized. When the half gear 43 disengages from the first gear 44, the conveying pipe 5 is reset under the action of the torsion spring 45, and the conveyor belt mechanism 1 is completed at this time. The upper door leaf of the civil air defense equipment is sprayed, and at the same time, the motor 41 drives the half gear 43 to continue to rotate and drives the second gear 11 to rotate, the second gear 11 drives the rotating shaft 2 9 to rotate, thereby driving the bevel gear 1 12 to rotate, the bevel gear 1 12 drives the bevel gear 2 13 to rotate, so that the conveyor belt mechanism 1 rotates, and drives the next door leaf fixing mechanism 2 to move to the opening of the device body 3. At this time, the half gear 43 disengages from the second gear 11 and engages with the first gear 44, thereby continuing the spraying work, thereby improving the spraying effect on the door leaf of the civil air defense equipment, avoiding the loosening of the nozzle 6, and solving the problem that the ball is easy to loosen and the adjustment process is cumbersome during the use of the spray gun of the existing door leaf spraying device of the civil air defense equipment, thereby reducing the spraying efficiency of the door leaf of the civil air defense equipment.
