[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0041] Please see Figure 1-13In this embodiment of the present invention, a coating machine production line includes a coating device 1, which has an unwinding device 2 on one side and a drying device 3 on the other side; the drying device 3 has a winding device 4 at the end away from the coating device 1.

[0042] The coating device 1 includes a hopper structure 12, a coating roller structure 11 above the hopper structure 12, a pressure roller structure 13 above the coating roller structure 11, a scraping structure 14 on one side of the coating roller structure 11, and a support 17 below the hopper structure 12, with side plates 16 fixedly connected to both ends of the top of the support 17.

[0044] One end of the transmission rod 126 is coaxially fixedly connected to a worm gear 127, the bottom of which is connected to the worm 128 in a transmission connection; both ends of the worm 128 are rotatably connected to mounting seats 129, and both mounting seats 129 are fixedly connected to the bracket 17; a handwheel 120 is coaxially fixedly connected to the end of the worm 128 away from the worm gear 127.

[0045] By adopting the above technical solution, the hopper 121 is used to hold the coating material. By rotating the handwheel 120, the two gears 125 can be rotated, thereby driving the rack 124 meshing with the gears 125 to move vertically and drive the hopper 121 to rise and fall, changing the height of the hopper 121. This makes it convenient to add coating material to the hopper 121 without causing leakage of coating material. In addition, when there is less coating material in the hopper 121, raising the height of the hopper 121 can ensure that the lower end of the coating roller 111 is always immersed in the coating material, ensuring that the coating work can be carried out normally.

[0046] In this embodiment, the coating roller structure 11 includes a coating roller 111, the two ends of which are rotatably connected to the two side plates 16 via bearings, and one end of the coating roller 111 extends to the outside of the side plate 16 and is coaxially fixedly connected to a driven gear 112; the bottom of the driven gear 112 meshes with the driving gear 113, and the central shaft of the driving gear 113 is rotatably connected to the bracket 17.

[0047] The driven gear 113 is coaxially fixedly connected to the driven synchronous belt 114 on the side away from the side plate 16.

Each of the two side plates 16 has a slider 138 fixedly connected to one side, and the side of each slider 138 away from the side plate 16 is slidably connected to two slide rails 137. The two slide rails 137 are fixedly connected to the two side plates 16.

[0050] By adopting the above technical solution, the space between the pressure roller 132 and the coating roller 111 is for the material to pass through; after the coating roller 111 carries the coating material to the surface of the material, the pressure roller 132 and the coating roller 111 work together to squeeze the material, which can make the coating material completely soak into the material, ensuring that the coating material does not just stay on the surface of the material, thus improving the coating effect; the cylinder 136 can drive the pressure roller 132 to rise and fall, thereby changing the size of the space between the pressure roller 132 and the coating roller 111, so that the pressure roller 132 and the coating roller 111 can squeeze materials of different thicknesses.

[0051] In this embodiment, the scraping structure 14 includes a scraper 141, one side of which is fixedly connected to a fixed plate 142; the bottom of the side of the fixed plate 142 away from the scraper 141 is attached to the top of the movable plate 144; a plurality of pressure blocks 143 are evenly fixedly connected to the top of the movable plate 144 by bolts, and the ends of the plurality of pressure blocks 143 away from the movable plate 144 are attached to the top of the fixed plate 142; the bottom of both ends of the movable plate 144 are respectively engaged with locking blocks 145, and one side of each locking block 145 is fixedly connected to two adjusting rods 146.

[0052] Both of the two adjusting rods 146 are threaded on the outside and are threaded to two threaded seats 147 respectively; the bottom of the two threaded seats 147 is fixedly connected to two support plates respectively, and the bottom of both ends of the movable plate 144 is respectively attached to the two support plates; the bottom of the two support plates is fixedly connected to two driving mechanisms 148 respectively; both driving mechanisms 148 are fixedly connected to two connecting plates 149, both connecting plates 149 are fixedly connected to two support rods 140, and the two ends of the two support rods 140 are fixedly connected to two side plates 16 respectively.

[0053] The drive mechanism 148 includes a connecting rod 1484, both ends of which are rotatably connected to rotating clamping plates 1482. The tops of the two rotating clamping plates 1482 are respectively fixedly connected to the bottoms of the two support plates. The ends of the two rotating clamping plates 1482 away from the scraper 141 are respectively fixedly connected to the telescopic rods of the two cylinders 1481.

[0054] Both sides of the two cylinders 1481 are rotatably connected to fixed clamping plates 1483, and the ends of the multiple fixed clamping plates 1483 away from the cylinders 1481 are fixedly connected to the connecting rods 1484; one end of the connecting rods 1484 is fixedly connected to the output end of the reducer 1485, and the input end of the reducer 1485 is fixedly connected to the output shaft of the motor 1486; both ends of the connecting rods 1484 are fitted with connecting tee pipes 1487, and the reducer 1485 is fixedly connected to one of the connecting tee pipes 1487; the bottoms of the two connecting tee pipes 1487 are respectively fixedly connected to the tops of the two connecting plates 149.

[0055] By adopting the above technical solution, after the coating work is completed, the doctor blade 141 can clean the surface of the coating roller 111, remove the coating material from the surface of the coating roller 111, and ensure the cleanliness of the coating roller 111; the motor 1486 drives the connecting rod 1484 to rotate, which in turn drives the drive mechanism 148 and the doctor blade 141 to rotate around the connecting rod 1484, thereby changing the position of the doctor blade 141. In addition, the cylinder 1481 can also drive the doctor blade 141 to rotate independently by means of the rotating clamp 1482, thereby changing the position of the doctor blade 141 and improving the mobility of the doctor blade 141. This does not affect the normal progress of the coating work, and cleaning can also be performed after the coating work is completed.

[0056] The working principle of this utility model is as follows: The hopper 121 is used to hold the coating material. By rotating the handwheel 120, two gears 125 can be rotated, thereby driving the rack 124 meshing with the gears 125 to move vertically and drive the hopper 121 to rise and fall, changing the height of the hopper 121. This facilitates the addition of coating material to the hopper 121 without causing leakage. In addition, when the coating material in the hopper 121 is low, raising the height of the hopper 121 ensures that the lower end of the coating roller 111 is always immersed in the coating material, ensuring that the coating work can proceed normally.

[0057] The space between the pressure roller 132 and the coating roller 111 is for material to pass through. After the coating roller 111 carries the coating material to the surface of the material, the pressure roller 132 and the coating roller 111 work together to squeeze the material, which allows the coating material to completely impregnate the material and ensures that the coating material does not just stay on the surface of the material, thus improving the coating effect. The cylinder 136 can drive the pressure roller 132 to rise and fall, thereby changing the size of the space between the pressure roller 132 and the coating roller 111, so that the pressure roller 132 and the coating roller 111 can squeeze materials of different thicknesses.

[0058] After the coating process is completed, the doctor blade 141 can clean the surface of the coating roller 111, removing the coating material and ensuring the cleanliness of the coating roller 111. The motor 1486 drives the connecting rod 1484 to rotate, which in turn drives the drive mechanism 148 and the doctor blade 141 to rotate around the connecting rod 1484, thereby changing the position of the doctor blade 141. In addition, the cylinder 1481 can also drive the doctor blade 141 to rotate independently using the rotating clamp 1482, thereby changing the position of the doctor blade 141 and improving the mobility of the doctor blade 141. This does not affect the normal operation of the coating process and cleaning can be performed after the coating process is completed.

[0059] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and 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.
