Description

Technical Field

[0001] The utility model relates to the technical field of roller coaters, in particular to a double-roller coater for plate spraying. Background Art

[0002] In the process of plate processing, in order to improve the corrosion resistance, wear resistance and aesthetics of the product, it is usually necessary to spray paint on the surface of the plate through a roller coater. Among them, in the double-roller roller coater, the uniform rubber roller and the uniform steel roller are key components. They are usually set in parallel to ensure that the paint can form a uniform coating between the two. This design allows the two rollers to fit closely and control the thickness and uniformity of the paint by adjusting the pressure between them. However, the existing roller coater does not have a drying function during coating, which easily causes waste of the coating glue, paint or ink.

[0003] In order to address the above problems, the existing Chinese patent with announcement number CN217222218U proposes a double-roller coater for the production of calcium silicate boards. The device generates heat through the operation of a heating tube, and the heat is transferred to the inside of the heating box through the heating plate to heat the air inside it. Then, the hot air is driven from the air inlet into the drying bin through the operation of the air inlet motor and the cooperation of the air outlet motor to heat the board, thereby achieving a drying effect.

[0004] However, although the above-mentioned double-roller coater for producing calcium silicate boards can discharge the heat generated by the heating tube into the drying chamber through multiple sets of fans to dry the boards, when the double-roller coater for producing calcium silicate boards is painting the boards, the paint applied on the upper edge of the boards is easy to slide to the side panels of the boards, thereby affecting the painting effect of the boards. Therefore, the utility model provides a double-roller coater for painting boards to meet the needs. Utility Model Content

[0030] like Figures 1 to 7 As shown, an embodiment of the utility model provides a double-roller roller coater for painting a plate, comprising a roller coater body 1, a conveyor belt mechanism 5, and a rotating roller 2 arranged on the roller coater body 1 through a fixed plate 20, the roller coater body 1 is provided with an exhaust cylinder 11 relative to the rotating roller 2, and a plurality of air outlets 13 are penetrated through the end surface of the exhaust cylinder 11 facing the conveyor belt mechanism 5, a support plate 6 is provided at the end of the roller coater body 1, a top plate 10 is provided on the support plate 6, a blower 7 is provided on the top of the top plate 10, a shunt pipe 15 connected to the air outlet 13 of the blower 7 is provided inside the top plate 10, the shunt pipe 15 is connected to the exhaust cylinder 11 through a connecting pipe, and a paddle plate 12 that fits the edge of the rotating roller 2 is relatively movable on both sides of the fixed plate 20, and the paddle plate 12 is inclined toward the conveyor belt mechanism 5.

[0031] Specifically, when the rotating roller 2 is spraying paint on the plate, the blower 7 is started to make the wind flow along the diverter pipe 15 and the connecting pipe to the exhaust duct 11, and discharged along the air outlet 13 to the side of the plate on the conveyor belt mechanism 5, thereby preventing the paint on the edge of the plate from falling to the side of the plate. At the same time, the wind flow can also speed up the drying speed of the paint. In addition, the paddle 12 can prevent the amount of paint on the edge of the rotating roller 2 from being too large, thereby preventing a large amount of paint on the edge of the rotating roller 2 from accumulating on the edge of the plate. The overall structure is simple, which is convenient for regulating the amount of paint on the plate, thereby preventing a large amount of paint from falling along the edge of the plate, improving the painting effect of the plate, and solving the problem that when the existing double-roller coating machine is painting the plate, the paint applied on the edge of the plate easily slides to the side plate of the plate, thereby affecting the painting effect of the plate.

[0032] like Figures 2 to 6 As shown, in the present embodiment, the exhaust cylinder 11 is arranged on the roller coater body 1 along the transmission direction of the conveyor belt mechanism 5, and a cover plate 14 is hinged at the air outlet 13, and the cover plate 14 is rotatably connected to the exhaust cylinder 11 through a rotating shaft 9, and a torsion spring 3 is sleeved on the rotating shaft 9, and the two ends of the torsion spring 3 are respectively fixedly connected to the cover plate 14 and the exhaust cylinder 11. Specifically, the cover plate 14 can be blown open by the wind discharged from the air outlet 13, and is reset under the action of the torsion spring 3 when the wind stops, thereby improving the protection of the exhaust cylinder 11 and the air outlet 13.

[0033] like Figure 4 and Figure 5 As shown, in the present embodiment, the interior of the top plate 10 is a hollow structure, and an exhaust scoop 19 is connected to the bottom of the shunt pipe 15. The exhaust scoop 19 is a hollow structure with openings at both ends. A plurality of exhaust holes 17 are penetrated at the bottom of the top plate 10 relative to the exhaust scoop 19. A heating pipe is fixedly connected to the top plate 10 between the exhaust holes 17 and the exhaust scoop 19. A controller 4 for controlling the blower 7 and the heating pipe is provided on the roller coating machine body 1. Specifically, after the blower 7 discharges the wind flow to the shunt pipe 15, the shunt pipe 15 will respectively transport the wind flow to the exhaust scoop 19 and the exhaust cylinder 11. The wind flow transported to the exhaust scoop 19 will blow toward the heating pipe, thereby discharging the hot air along the exhaust hole 17 and drying the plate on the conveyor belt mechanism 5, thereby improving the drying efficiency of the paint on the plate and further avoiding the phenomenon of paint falling along the edge of the plate. It should be noted that the installation of the heating pipe and the connection with the controller 4 are prior arts and will not be described in detail here.

[0034] like Figure 2 and Figure 7 As shown, in the present embodiment, the dial plate 12 is movably connected with the fixed plate 20, and an adjusting mechanism 8 for adjusting the dial plate 12 is provided on the fixed plate 20. The adjusting mechanism 8 comprises an adjusting bolt 81, which penetrates through and is threadedly connected to the fixed plate 20, and the adjusting bolt 81 is rotatably connected with the dial plate 12. A movable rod 82, a first end of which is fixedly connected with the dial plate 12, and a second end of the movable rod 82 is movably connected with the fixed plate 20, and a second end of the movable rod 82 is fixedly connected with a limiting plate 83. A movable groove 84 for the limiting plate 83 to move is provided in the fixed plate 20. Specifically, the position of the dial plate 12 can be adjusted conveniently through the adjusting mechanism 8, so as to adjust the position of the paint on the rotating roller 2 according to the width of the plate, thereby improving the application range of the device.

[0035] Working principle:

[0036] First, the position of the paddle 12 is adjusted by the adjusting mechanism 8 according to the width of the plate. Then, when the rotating roller 2 is used to spray paint on the plate, the blower 7 is started to discharge the wind along the shunt pipe 15 and the connecting pipe to the exhaust tube 11, and discharged along the air outlet 13 to the side of the plate on the conveyor belt mechanism 5, thereby preventing the paint on the edge of the plate from falling to the side of the plate. At the same time, the wind delivered to the exhaust scoop 19 will blow to the heating pipe, thereby discharging the hot air along the exhaust hole 17 and drying the plate on the conveyor belt mechanism 5. The overall structure is simple, which is convenient for regulating the amount of paint on the plate, thereby preventing a large amount of paint from falling along the edge of the plate, improving the painting effect of the plate, and solving the problem that when the existing double-roller coating machine is painting the plate, the paint applied on the edge of the plate is easy to slide to the side plate of the plate, thereby affecting the painting effect of the plate.
