Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper processing technology, and more specifically, to a spraying device for coating the surface of blueprint paper. Background Technology
[0002] Blueprint paper, also known as "blue paper," is a type of chemically coated paper specifically designed for engineering design and machinery manufacturing. It is an indispensable tool in production, scientific research, and construction. It is typically made from ferricyanide and ferric salt-sensitized paper or cloth, exposed to light, and then rinsed and developed with water to produce a blue background with a white image. It is particularly suitable for printing maps, mechanical drawings, and architectural plans.
[0003] In the production and use of blueprints, liquid is generally required to treat the blueprints. In this process, a spray nozzle is usually used to spray the liquid. However, during spraying, due to the small weight of the paper, the spraying force may cause the paper to move, resulting in uneven spraying. If the position of the paper is to be fixed, a paper pressing device is required to fix the position of the paper, but this will cause some areas of the paper surface to be unsprayed, resulting in the need for secondary processing and reduced production efficiency.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1 to 6 As shown, this utility model provides a spraying device for coating blueprint paper surfaces, including support legs 1, four support legs 1 are provided, a platform 2 is fixedly connected to the top of the four support legs 1, a PLC control device 3 is fixedly connected to the top of the platform 2, a bracket 4 is fixedly connected to the top of the platform 2, a transmission assembly is provided on the outside of the bracket 4, the transmission assembly includes a limiting assembly at the bottom, the limiting assembly includes a first connecting plate 5 fixedly connected to the bottom of the transmission assembly, four connecting columns 6 are fixedly connected to the bottom of the first connecting plate 5, a work box 7 is fixedly connected to the bottom of the connecting columns 6, a first sliding rod 8 is slidably connected inside the work box 7, the first sliding rod 8 passes through the work box 7, a limit frame 9 is fixedly connected to the bottom of the work box 7, and a spring 10 is fixedly connected between the limit frame 9 and the work box 7.
[0025] The movement of the first connecting plate 5 drives the connecting column 6 to move, which in turn drives the work box 7 to move, which in turn drives the first sliding rod 8 and the limiting frame 9 to move, so that the limiting frame 9 covers the paper, thereby restricting the position of the paper, so that the paper will not be displaced due to the spraying force after being sprayed, thereby reducing the possibility of uneven paper spraying, reducing the possibility of secondary processing, and improving production efficiency.
[0026] After the bottom of the limiting frame 9 abuts against the top of the platform 2, it continues to move, so that the first slide bar 8 enters the working box 7, thereby compressing the spring 10 and forming a buffer.
[0027] The transmission assembly includes a first screw 11 fixedly connected to the top of the first connecting plate 5, a second slide rod 16 fixedly connected to the top of the first connecting plate 5, the second slide rod 16 passing through the bracket 4 and slidably connected, the first screw 11 passing through the bracket 4 and rotatably connected, a first screw cylinder 12 threadedly connected to the outside of the first screw 11, the bottom of the first screw cylinder 12 rotatably connected to the top of the bracket 4, and a first gear 13 fixedly connected to the outside of the first screw cylinder 12. There are two first gears 13, and the two first gears 13 mesh with each other.
[0028] The rotation of the two first gears 13 drives the first screw barrel 12 to rotate, which in turn drives the first screw 11 to move, and thus the first connecting plate 5 to move.
[0029] The transmission assembly also includes a first transmission rod 14 fixedly connected inside the first gear 13. The bottom of the first transmission rod 14 is rotatably connected to the top of the bracket 4. A first motor 15 is fixedly connected to the top of the first transmission rod 14.

A nozzle 25 is fixedly connected to the bottom of the flow plate 24. The nozzle 25 is electrically connected to the PLC control device 3.
[0032] The spray assembly also includes a second gear 21 fixedly connected to the outside of the second screw barrel 19. There are two second gears 21, which mesh with each other.

The second motor 23 is electrically connected to the PLC control device 3, and the outside of the second motor 23 is fixedly connected to the outside of the first vertical plate 20.
[0033] The second motor 23 drives the second transmission rod 22 to rotate, which in turn drives the two second gears 21 to rotate, which in turn drives the second screw barrel 19 to rotate, which in turn causes the second screw barrel 19 to rotate outside the second screw 18, which in turn drives the flow plate 24 to move, which in turn drives the nozzle 25 to move, so that the nozzle 25 can move at a constant speed above the paper, which facilitates uniform spraying of the paper.
[0034] The top of the flow plate 24 is provided with a stabilizing component, which includes two transmission blocks 26 fixedly connected to the top of the flow plate 24. A third slide rod 27 is slidably connected inside the transmission block 26, and the two ends of the third slide rod 27 are fixedly connected to the inside of the working box 7.
[0035] The position of the transmission block 26 is restricted by the third slide bar 27, thereby restricting the position of the flow plate 24 and ensuring the stability of the nozzle 25 movement.
[0036] The work box 7 is provided with a winding assembly on its outer side. The winding assembly includes two second upright plates 28 fixedly connected to the outer side of the work box 7.

The end of the transmission pipe 31 passes through the flow plate 24 and is fixedly connected.
[0037] The coil spring 30 drives the winding roller 29 to rotate, thereby causing the transmission tube 31 to be wound onto the winding roller 29, thus reducing the impact of the slack state of the transmission tube 31 on the operation of the work box 7.
[0038] The work box 7 is equipped with a blower assembly, which includes a mounting cylinder 32 fixedly connected inside the work box 7. A second connecting plate 33 is fixedly connected inside the mounting cylinder 32. Two ventilation plates 34 are fixedly connected between the second connecting plate 33 and the mounting cylinder 32.

A third transmission rod 36 is fixedly connected to the transmission end of the third motor 35. Fan blades 37 are fixedly connected to the outside of the third transmission rod 36.
[0039] After the limiting frame 9 restricts the position of the paper, the third motor 35 drives the third transmission rod 36 to rotate, which in turn drives the fan blade 37 to rotate, thereby blowing the paper. This can both press the paper and air dry the coated paper, thus further improving work efficiency.
[0040] The working principle and usage process of this utility model are as follows: The first motor 15 drives the first transmission rod 14 to rotate, which in turn drives the two first gears 13 to rotate, which in turn drives the first screw barrel 12 to rotate, which in turn drives the first screw 11 to move, which in turn drives the first connecting plate 5 to move, which in turn drives the connecting column 6 to move, which in turn drives the working box 7 to move, which in turn drives the first sliding rod 8 and the limiting frame 9 to move, so that the limiting frame 9 covers the paper, thereby limiting the position of the paper. This prevents the paper from shifting due to the impact of the spraying after being sprayed, thereby reducing the possibility of uneven paper spraying, reducing the possibility of secondary processing, and improving production efficiency.
[0041] Then, the third motor 35 is started, which drives the third transmission rod 36 to rotate, which in turn drives the fan blade 37 to rotate. This blows the paper, which can both press the paper and dry the coated paper, thereby further improving work efficiency.
