Technical Field

[0001] The utility model belongs to the technical field of coating equipment, and particularly relates to a coating device with adjustable coating spacing. Background Technique

[0002] A coating machine is a device used to coat a layer of glue, coating, ink, etc. with specific functions on the surface of a substrate, which can change the properties, appearance or functions of the substrate; according to different coating methods, the current coating devices can be divided into blade coating devices, roller coating devices, spray coating devices, curtain coating devices, slot coating devices, etc.; the application range of coating machines is very wide, mainly including paper coating, film coating, fabric coating, electronic product coating, etc., and it is an indispensable device in modern industry.

[0003] In the existing coating devices, the working gap between the coating structure and the adjacent working roller mostly adopts a fixed distance design, which is not easy to adjust, and the applicable range is low. When the coated material is too thick and needs to be adjusted, usually the staff manually disassembles and installs the coating structure or the working roller to adjust the coating spacing, which is time-consuming and laborious, affects the working efficiency of the coating device, and the surface of the material is relatively easy to adhere to dust, thus affecting the coating effect of the material and reducing the coating quality.

[0004] Therefore, a coating device with adjustable coating spacing is needed to solve the problems in the prior art that the coating device is not easy to adjust the coating spacing according to the thickness of the material, and the dust attached to the surface of the material easily affects the coating effect. Summary of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solution: A coating device with adjustable coating spacing, including a workbench, two symmetrically distributed U-shaped frames are fixedly connected to the top surface of the workbench, slide plates are slidably connected to the inner walls of the two U-shaped frames, a coating structure is installed between the adjacent end walls of the tops of the two slide plates, and the same adjusting mechanism is arranged in the two U-shaped frames;

[0007] The adjusting mechanism includes a forward and reverse motor, which is fixedly connected to the bottom of the outer wall of one end of a U-shaped frame. The output end of the forward and reverse motor rotatably penetrates the corresponding U-shaped frame and is coaxially fixedly connected with a transmission shaft. The end of the transmission shaft away from the forward and reverse motor is rotatably connected to the inner wall of one end of the other U-shaped frame. Two parallel distributed driving bevel gears are tightly sleeved on the outer surface of the transmission shaft. The driving bevel gears are meshed with vertically arranged driven bevel gears. The top of the driven bevel gear is coaxially fixedly connected with a lifting lead screw. An installation plate is rotatably connected to the outer surface of the lifting lead screw. The same moving plate is threadedly connected to the outer surfaces of the two lifting lead screws. A limiting block is coaxially fixedly connected to the top of the lifting lead screw.

[0008] It should be noted in the solution that through holes are respectively formed in the outer walls of one ends of the two sliding plates. A rotating shaft is rotatably connected between the inner walls of one ends of the two U-shaped frames through the two through holes. A conveying roller is tightly sleeved on the outer surface of the rotating shaft.

[0009] Furthermore, it is worth noting that two parallel distributed first fixing plates are fixedly connected to one side of the top surface of the workbench. A unwinding roller is arranged between the outer walls of the adjacent ends of the two first fixing plates. Two parallel distributed second fixing plates are fixedly connected to the other side of the top surface of the workbench. A winding roller is arranged between the outer walls of the adjacent ends of the two second fixing plates.

[0010] Even further, it should be noted that two parallel distributed L-shaped rods are fixedly connected to the outer wall of one side of the coating structure. The same cleaning brush plate is fixedly connected to the bottom surfaces of the vertical sections of the two L-shaped rods.

[0011] As a preferred implementation manner, the two installation plates are symmetrically distributed and the outer walls of one ends are respectively fixedly connected to the inner walls of one ends of the adjacent U-shaped frames. The outer walls of the two ends of the moving plate are respectively fixedly connected to the outer walls of the ends of the two sliding plates away from the U-shaped frames.

[0012] As a preferred implementation manner, the outer surface of the rotating shaft is slidably connected to the inner surface of the through hole. The bottom of the brush on the cleaning brush plate and the bottom of the coating structure are at the same level.

[0013] Compared with the prior art, the coating device with adjustable coating spacing provided by the present utility model has at least the following beneficial effects:

[0014] (1) Under the action of the adjusting mechanism, the forward and reverse motor drives the driving bevel gear to rotate, so that the driven bevel gear drives the lifting lead screw to rotate, and then the moving plate drives the coating structure to rise or fall, realizing the adjustment of the coating spacing. The operation is simple, effectively avoiding the problem that the coating device is not easy to adjust the coating spacing according to the thickness of the material.

[0015] (2) By means of the provided cleaning brush plate, when the coating structure moves, the cleaning brush plate is driven to move synchronously. When the bottom of the coating structure is in contact with the top surface of the material, the bottom of the brush on the cleaning brush plate contacts the top surface of the material. When coating the material, the cleaning brush plate brushes and cleans the material before coating, removing the dust adhering to the surface of the material, effectively avoiding the problem that the dust adhering to the surface of the material easily affects the coating effect.

Detailed Embodiment

[0021] The following further describes the present utility model in conjunction with embodiments.

[0022] Please refer to Figures 1-4 , the present utility model provides a coating device with adjustable coating spacing, including a workbench 1, two symmetrically distributed U-shaped frames 2 are fixedly connected to the top surface of the workbench 1, sliding plates 3 are slidably connected to the inner walls of the two U-shaped frames 2, a coating structure 4 is installed between the adjacent end walls of the tops of the two sliding plates 3, and the same adjusting mechanism 5 is arranged in the two U-shaped frames 2;

[0023] The adjusting mechanism 5 includes a forward and reverse motor 51. The forward and reverse motor 51 is fixedly connected to the bottom of the outer wall of one end of the U-shaped frame 2. The output end of the forward and reverse motor 51 rotatably penetrates through the corresponding U-shaped frame 2 and is coaxially and fixedly connected with a transmission shaft 52. The end of the transmission shaft 52 away from the forward and reverse motor 51 is rotatably connected to the inner wall of one end of the other U-shaped frame 2. Two driving bevel gears 53 distributed in parallel are tightly sleeved on the outer surface of the transmission shaft 52. The driving bevel gear 53 is meshed with a vertically arranged driven bevel gear 54. The top of the driven bevel gear 54 is coaxially and fixedly connected with a lifting screw rod 55. The outer surface of the lifting screw rod 55 is rotatably connected with a mounting plate 56. The same moving plate 57 is threadedly connected to the outer surfaces of the two lifting screw rods 55. The top of the lifting screw rod 55 is coaxially and fixedly connected with a limiting block 58.

[0024] Further as Figure 3 and Figure 4 shown, it is worth specifically stating that movable grooves 6 are respectively formed through the outer walls of one ends of the two sliding plates 3. A rotating shaft 7 is rotatably connected between the inner walls of one ends of the two U-shaped frames 2 through the two movable grooves 6. A conveying roller 8 is tightly sleeved on the outer surface of the rotating shaft 7.

[0025] Further as Figure 1 shown, it is worth specifically stating that two first fixing plates 9 distributed in parallel are fixedly connected to one side of the top surface of the workbench 1. A pay-off roller 10 is arranged between the outer walls of the adjacent ends of the two first fixing plates 9. Two second fixing plates 11 distributed in parallel are fixedly connected to the other side of the top surface of the workbench 1. A take-up roller 12 is arranged between the outer walls of the adjacent ends of the two second fixing plates 11.

[0026] Further as Figure 1 and Figure 4 shown, it is worth specifically stating that two L-shaped rods 13 distributed in parallel are fixedly connected to one side outer wall of the coating structure 4. The same cleaning brush plate 14 is fixedly connected to the bottom surfaces of the vertical sections of the two L-shaped rods 13.

[0027] Further as Figure 2 and Figure 3 shown, it is worth specifically stating that the two mounting plates 56 are symmetrically distributed and the outer walls of one ends are respectively fixedly connected to the inner walls of one ends of the adjacent U-shaped frames 2, which is convenient for driving the lifting screw rod 55 to rotate through the cooperation of the driving bevel gear 53 and the driven bevel gear 54. The outer walls of the two ends of the moving plate 57 are respectively fixedly connected to the outer walls of the ends of the two sliding plates 3 away from the U-shaped frames 2. The rotation of the lifting screw rod 55 drives the moving plate 57 to rise or fall, realizing the adjustment of the coating spacing.

[0028] Further as Figure 3 and Figure 4As shown, it is worth specifically noting that the outer surface of the rotating shaft 7 is slidably connected to the inner surface of the movable groove 6. When the lifting lead screw 55 rotates, it facilitates the up and down movement of the two sliding plates 3 within the two U-shaped frames 2. The bottom of the brush on the cleaning brush plate 14 is at the same level as the bottom of the coating structure 4, which is convenient for cleaning the material to be coated, and avoids the influence of dust attached to the material surface on the coating effect.

[0029] In summary: When this coating device is in use, first, the material to be coated on the unwinding roller 10 is passed through between the coating structure 4 and the conveying roller 8 and fixed on the winding roller 12. Then, according to the actual thickness of the material, the forward and reverse motor 51 is started to rotate forward to drive the transmission shaft 52 to rotate clockwise. After the transmission shaft 52 rotates, it drives the two parallel distributed driving bevel gears 53 to rotate. Under the meshing action, the driving bevel gear 53 drives the driven bevel gear 54 to rotate, thereby driving the two lifting lead screws 55 to rotate in the same direction. Under the action of the thread, the lifting lead screw 55 drives the moving plate 57 to move downward. At the same time, under the sliding fit of the movable groove 6 and the rotating shaft 7, the moving plate 57 drives the two sliding plates 3 and the coating structure 4 installed on the two sliding plates 3 to move downward. When the bottom of the coating structure 4 is in contact with the top surface of the material, the unwinding roller 10 and the winding roller 12 are started to realize the coating operation of the material. The operation is simple and effectively avoids the problem that the coating device is not easy to adjust the coating spacing according to the thickness of the material.

[0030] When the coating structure 4 moves towards the top surface of the material under the action of the adjusting mechanism 5, the coating structure 4 simultaneously drives the two L-shaped rods 13 and the cleaning brush plate 14 fixed to the bottom surfaces of the two L-shaped rods 13 to move synchronously. When the bottom of the coating structure 4 is in contact with the top surface of the material, the bottom of the brush on the cleaning brush plate 14 is in contact with the top surface of the material. In this case, when the material is coated, the cleaning brush plate 14 will brush and clean the material before coating, removing the dust adhered to the material surface, and effectively avoiding the problem that the dust attached to the material surface easily affects the coating effect.

[0031] The forward and reverse motor 51 can be purchased on the market. The forward and reverse motor 51 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed. Therefore, it is not repeated in the specification.
