Description

Technical Field

[0001] The utility model relates to the technical field of spraying, and particularly relates to a spraying device for a nano-silica coating. Background Technique

[0002] In order to improve the service life of metal plates for construction, a nano-silica coating is usually sprayed on the surface of the metal plate by a precision pneumatic spray gun in a spraying device, so that silica particles are dispersed and fixed on the surface of the metal plate in extremely small sizes to form a thin film, thereby protecting the surface of the metal plate.

[0003] After retrieval, the Chinese patent "Spraying Device for Metal Plate Processing" with the authorization announcement number "CN218013455U" realizes the angular rotation of one side of the clamping seat through a connecting shaft, a sliding sleeve, a clamping seat, a worm gear and a worm, and then realizes the flipping of the metal plate, ensuring the comprehensiveness of spraying the front and back sides of the metal plate by the spraying device.

[0004] The above angular rotation of one side of the clamping seat through a worm gear and a worm is prone to difficult flipping of the metal plate due to the certain weight of the metal plate, and thus affects the spraying efficiency of the metal plate.

[0005] Therefore, a spraying device for a nano-silica coating is proposed to solve the above problems. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] During specific implementation: As Figures 1-4As shown in the figure, a spraying device for nano-level silica coating includes: a spraying box 1, a spraying gun barrel 2 is provided at the inner top of the spraying box 1, and a bidirectional lead screw 3 is rotatably connected to the inner bottom of the spraying box 1; an adjustment mechanism 4 is arranged inside the spraying box 1; wherein, the adjustment mechanism 4 includes two slide plates 41 slidably connected to the inner bottom of the spraying box 1, the inner wall of the slide plate 41 is threadedly connected to the surface of the bidirectional lead screw 3, one side of the slide plate 41 is rotatably connected to a clamping block 42, one end of the clamping block 42 is fixedly connected to a first gear 44, the lower end of the surface of the first gear 44 is meshed with a first rack 43, a first air cylinder 46 is fixedly connected to the inner bottom of the spraying box 1, the rear end of the first air cylinder 46 is fixedly connected to the surface of a connecting rod 45, the inner wall of the first rack 43 is slidably connected to the surface of the connecting rod 45, a stop frame 412 is fixedly connected to the inner bottom of the spraying box 1, the lower end of the surface of the slide plate 41 is slidably connected to the surface of the stop frame 412, the bottom of the stop frame 412 is located at the upper end of the surface of the bidirectional lead screw 3, a limiting rod 414 is fixedly connected to the inner bottom of the spraying box 1, the inner wall of the connecting rod 45 is slidably connected to the surface of the limiting rod 414, a ball 413 is rotatably connected to the lower end of the surface of the connecting rod 45, and the surface of the ball 413 is rotatably connected to the inner bottom of the spraying box 1.

[0025] A lead screw is rotatably connected to the inner top of the spraying box 1, a first servo motor is fixedly connected to the inner top of the spraying box 1, the output shaft of the first servo motor is fixedly connected to one end of the lead screw, a slide bar is fixedly connected to the inner top of the spraying box 1, a slider is threadedly connected to the surface of the lead screw, the bottom of the slider is fixedly connected to the upper end of the surface of the spraying gun barrel 2, a storage tank is fixedly connected to the inside of the spraying box 1, a liquid extraction pump is communicated with the top of the storage tank, and the liquid outlet end of the liquid extraction pump is connected to one end of the spraying gun barrel 2, a second servo motor is fixedly connected to the inner bottom of the spraying box 1, and the output shaft of the second servo motor is fixedly connected to one end of the bidirectional lead screw 3.

[0026] When a nano - silica coating needs to be sprayed on a metal plate, the metal plate is placed in the spraying box 1. Manually turn on the second servo - motor. The output shaft of the second servo - motor rotates to drive the bidirectional lead screw 3 to rotate. The rotation of the bidirectional lead screw 3 drives the sliding plate 41 and the clamping block 42 to move, so that the two clamping blocks 42 clamp the side of the metal plate. Manually turn off the second servo - motor and turn on the liquid - pumping pump. The liquid - pumping pump extracts the silica particles in the storage tank and transports them into the spraying gun barrel 2. The spraying gun barrel 2 disperses and fixes the silica particles on the surface of the metal plate in extremely tiny sizes to form a thin film. When a silica coating needs to be sprayed on the bottom surface of the metal plate, manually turn on the first cylinder 46. One end of the first cylinder 46 moves to drive the connecting rod 45 to move. The movement of the connecting rod 45 drives the first rack 43 to move. The movement of the first rack 43 drives the first gear 44 to rotate. The rotation of the first gear 44 drives the clamping block 42 and the clamped metal plate to rotate. The connecting rod 45 moves and abuts against one end of the limiting rod 414. Manually turn off the first cylinder 46, so that the bottom surface of the metal plate faces the top. At this time, the spraying gun barrel 2 sprays silica particles on the metal plate. When the silica coating does not need to be sprayed on the metal plate, manually turn off the power supply of the liquid - pumping pump.

[0027] As Figure 4 shown, support blocks 47 are hinged to both the top and bottom of the clamping block 42. A second gear 48 is fixedly connected to the front end of the support block 47. A second rack 49 is meshed with the surface of the second gear 48. A second cylinder 410 is fixedly connected to the top of the sliding plate 41. The bottom end of the second cylinder 410 penetrates through the sliding plate 41 and is fixedly connected to the top of the second rack 49. A limiting groove 411 is opened at the front end of the sliding plate 41. The surface of the second rack 49 is slidably connected to the inner wall of the limiting groove 411. A polytetrafluoroethylene coating is provided on the surface of the support block 47.

[0028] When the bottom surface of the metal plate is flipped to the top, the two second cylinders 410 are controlled by the same power switch. Manually turn on the second cylinders 410. The upward movement of the bottom ends of the second cylinders 410 drives the second racks 49 upward. The upward movement of the second racks 49 drives the two second gears 48 to rotate. The rotation of the two second gears 48 drives their respective support blocks 47 to flip, so that one of the support blocks 47 is away from the metal plate and in a vertical state, and the top of the other support block 47 contacts the bottom of the metal plate. Because a polytetrafluoroethylene coating is provided on the surface of the support block 47, after the support block 47 contacts the metal plate, the silica coating on the metal plate will not adhere to the support block 47, so that the support block 47 on the top of the metal plate will not block the spraying, and the spraying gun barrel 2 can spray the top surface of the metal plate comprehensively.

[0029] When the utility model is in use, place the metal plate on the top of one of the support blocks 47, manually turn on the second servo motor, the output shaft of the second servo motor rotates to drive the bidirectional lead screw 3 to rotate, the bidirectional lead screw 3 rotates to drive the slide plate 41 and the clamping block 42 to move, so that the two clamping blocks 42 clamp the side of the metal plate. Manually turn off the second servo motor and turn on the liquid extraction pump. The liquid extraction pump extracts the silicon dioxide particles in the storage tank and transports them into the spraying gun barrel 2. The spraying gun barrel 2 disperses and fixes the silicon dioxide particles on the surface of the metal plate in extremely small sizes to form a thin film. At this time, manually turn on the first cylinder 46. One end of the first cylinder 46 moves to drive the clamping block 42 and the clamped metal plate to rotate through the connecting rod 45, the first rack 43 and the first gear 44. The connecting rod 45 moves and abuts against one end of the limiting rod 414. Manually turn off the first cylinder 46 to make the bottom to the top of the metal plate. Manually turn on the second cylinder 410. The bottom end of the second cylinder 410 moves upward to drive the two support blocks 47 to turn over through the second rack 49 and the second gear 48, so that one of the support blocks 47 is away from the metal plate and is in a vertical state, and the top of the other support block 47 contacts the bottom of the metal plate. At this time, spray the silicon dioxide particles on the metal plate through the spraying gun barrel 2, so that the support block 47 on the top of the metal plate will not block the spraying, and the spraying gun barrel 2 can spray the top surface of the metal plate comprehensively.

[0030] It should be noted that in the above description, the spraying box 1, the liquid extraction pump, the first servo motor, the second servo motor, the wire cylinder, the bidirectional lead screw 3, the spraying gun barrel 2, the first cylinder 46 and the second cylinder 410 are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply of the first servo motor, the second servo motor, the first cylinder 46 and the second cylinder 410 can be powered by an internal power supply or by the mains. The specific power supply method is selected according to the situation and will not be elaborated here.

[0031] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. The narrative way of this specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
