[0031] A water-based paint roller coater according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0032] Reference Figure 1 The utility model aims to provide an embodiment of a water-based paint roller coater.

[0033] To solve the pressure regulation problem, such as Figure 1-Figure 4 As shown, it comprises a conveyor 1 , a support 2 is arranged above the conveyor 1 , a roller 3 is arranged inside the support 2 , and a feeding member 4 is arranged on the inner side wall of the conveyor 1 above the roller 3 .

[0034] The roller member 3 includes a coating roller 5 and a material leveling roller 11, the material leveling roller 11 is rotatably connected to the inner side of the bracket 2 via a rotating shaft 2 10, the two sides of the coating roller 5 are rotatably connected to sliders 9 via a rotating shaft 1 8, a slide groove 7 is provided on the inner wall of the bracket 2, the slider 9 is slidably connected to the inner wall of the slide groove 7, the inner wall of the bracket 2 is threadedly connected to a threaded rod 1 6, and the end of the threaded rod 6 is rotatably connected to the side wall of the slider 9.

[0035] When the device is in use, the feeding member 4 can convey the paint to the surface of the sizing roller 11, and then the paint roller 5 and the sizing roller 11 can transfer the paint by contacting each other. After the transfer, the paint is evenly wrapped on the outer surface of the paint roller 5. At this time, the plate can be conveyed through the conveyor 1, and the paint roller 5 transfers the paint to the surface of the plate after contacting the plate. When in use, the threaded rod 6 can be rotated to adjust the static friction force of the threaded pair between the threaded rod 6 and the bracket 2, thereby changing the contact pressure between the sizing roller 11 and the paint roller 55.

[0036] By providing components such as a threaded rod 6 and a slider 9, the device can adjust the pressure between the coating roller 5 and the leveling roller 11 through the threaded rod 6 during coating transfer, thereby ensuring the reliability of the coating transfer from the leveling roller 11 to the coating roller 5 and preventing an increase in the load on the equipment components caused by excessive contact pressure between the coating roller 5 and the leveling roller 11.

[0037] To solve the height adjustment problem, such as Figure 3 As shown, one end of the bracket 2 is rotatably connected to the conveyor 1, and a limiting groove 14 is provided on the inner wall of the other end of the bracket 2. The inner wall of the limiting groove 14 is movably limited by a limiting boss 15, and a transition block 13 is welded to the side wall of the limiting boss 15. The inner wall of the transition block 13 is threadedly connected to a threaded rod 12, and the end of the threaded rod 12 is rotatably connected to the conveyor 1.

[0038] When roller coating is performed on plates of different sizes, the threaded rod 12 can be rotated, so that the support 2 can be rotated by utilizing the threaded connection between the threaded rod 12 and the transition block 13, thereby adjusting the height of the coating roller 5 relative to the conveying surface of the conveyor 1.

[0039] The device, by setting a threaded rod 12, a transition block 13, a limiting groove 14 and a limiting boss 15, can rotate the bracket 2, thereby adjusting the height of the coating roller 5 relative to the conveying surface of the conveyor 1, so that the roller coating height can be specifically adjusted according to the actual processing plate.

[0040] In order to solve the quantitative feeding problem, such as Figure 4As shown, the feeding member 4 includes a plurality of cylinder bodies 19 fixed to the inner side above the bracket 2 and a crankshaft 21 rotatably connected to the inner side of the top of the bracket 2. The outer wall of the crankshaft 21 is rotatably connected to a plurality of connecting rods 22. The other end of the connecting rod 22 is rotatably connected to a piston 23. The piston 23 is movably fitted to the inner wall of the cylinder body 19.

[0041] The bottom of the cylinder body 19 is respectively provided with a feed port 17 and a discharge port 18, the other end of the discharge port 18 is connected to a nozzle 16, the spraying port of the nozzle 16 is facing the material leveling roller 11, and the other end of the feed port 17 is connected to a accumulator. In this embodiment, the specific type of the accumulator is not limited, and it can be a box body, a tank body and other components, which are intended to store paint and are conventional knowledge / means of technicians in this field. This embodiment does not make creative labor improvements to it, so it will not be repeated.

[0042] The inner walls of the feed port 17 and the discharge port 18 are both provided with a one-way valve. The one-way valve passage direction in the discharge port 18 is from the cylinder body 19 to the nozzle 16, and the one-way valve passage direction in the feed port 17 is from the accumulator to the cylinder body 19.

[0043] When the crankshaft 21 rotates, it can drive the piston 23 to reciprocate along the inside of the cylinder 19 through the connecting rod 22. During this process, when negative pressure appears in the cylinder 19, the paint in the storage container is sucked into the cylinder 19 through the feed port 17. When positive pressure appears in the cylinder 19, the paint stored in the cylinder 19 can be transported to the nozzle 16 through the discharge port 18, and then sprayed onto the surface of the material leveling roller 11 by the nozzle 16.

[0044] The device is provided with a feeding member 4, which is composed of a crankshaft 21, a connecting rod 22, a piston 23, etc., so that quantitative feeding can be achieved by controlling the rotation speed of the crankshaft 21, thereby ensuring the uniformity of roller coating.

[0045] An electric motor 20 is fixed to an outer wall of one side of the bracket 2 by bolts, and an output shaft of the electric motor 20 is connected to an end of a crankshaft 21 by a coupling. When the electric motor 20 is started, it can drive the crankshaft 21 to rotate.

[0046] In order to solve the problem of adaptively adjusting the feeding amount, such as Figure 4 As shown, the crankshaft 21 and the second rotating shaft 10 are coupled with each other through a synchronization assembly 24 .

[0047] In this embodiment, the specific type of the synchronization component 24 is not limited, and it can be any one of a chain drive, a belt drive and a gear drive. In this embodiment, a belt drive is preferably used, and the transmission ratio from the crankshaft 21 to the rotating shaft 10 can be changed by adjusting the size of the pulley in the belt drive.

[0048] During roller coating, the linear speed of the coating roller 5 needs to be the same as the conveying speed of the conveyor 1 for the plate, and when the leveling roller 11 rotates, it can drive the coating roller 5 to rotate through contact. At the same time, when the conveying speed of the plate is faster and the rotation speed of the leveling roller 11 is faster, the corresponding rotation speed of the crankshaft 21 is faster, so that the feeding frequency is higher and the feeding amount is larger, and vice versa.

[0049] Based on adjusting the feeding speed by the rotation speed of the crankshaft 21, the device uses the synchronization component 24 to match the rotating shaft 10 and the crankshaft 21, so that the feeding speed and the conveying speed of the plate can be adaptively adjusted, ensuring the uniformity of the coating thickness of the roller coating.

[0050] Working principle: the feeding member 4 can convey the paint to the surface of the material leveling roller 11, and then the paint roller 5 and the material leveling roller 11 realize the transfer of the paint by contacting. After the transfer, the paint is evenly wrapped on the outer surface of the paint roller 5. At this time, the plate can be conveyed through the conveyor 1. After the paint roller 5 contacts the plate, the paint is transferred to the surface of the plate. When in use, the threaded rod 6 can be rotated to adjust the static friction of the threaded pair between the threaded rod 6 and the bracket 2, thereby changing the contact pressure between the material leveling roller 11 and the paint roller 55. At the same time, when roller coating plates of different sizes, the threaded rod 2 12 can be rotated, so as to utilize the threaded connection between the threaded rod 2 12 and the transition block 13 to rotate the bracket 2, thereby adjusting the height of the paint roller 5 relative to the conveying surface of the conveyor 1, and when the crankshaft 21 rotates When the cylinder 19 rotates, it can drive the piston 23 to reciprocate along the inside of the cylinder 19 through the connecting rod 22. During this process, when negative pressure appears in the cylinder 19, the paint in the storage container is sucked into the cylinder 19 through the feed port 17. When positive pressure appears in the cylinder 19, the paint stored in the cylinder 19 can be transported to the nozzle 16 through the discharge port 18, and then sprayed onto the surface of the leveling roller 11 by the nozzle 16. Finally, during roller coating, the linear speed of the paint roller 5 needs to be the same as the conveying speed of the conveyor 1 for the plate. When the leveling roller 11 rotates, it can drive the paint roller 5 to rotate through contact. At the same time, the faster the conveying speed of the plate and the faster the rotation speed of the leveling roller 11, the faster the corresponding rotation speed of the crankshaft 21, so that the higher the feeding frequency and the larger the feeding amount, and vice versa.
