Technical Field

[0001] This utility model relates to the field of vertical coating machine technology, and in particular to a coating head for a vertical coating machine with adjustable spacing. Background Technology

[0002] Vertical coating machines can achieve multi-layer coating processes, sequentially coating different functional coatings onto the substrate to produce packaging materials with composite functions. The coating head mainly consists of a coating roller and a back roller. The coating head ensures that the coating can be evenly distributed on the surface of the substrate, avoiding coating defects such as uneven thickness, streaks, and spots.

[0003] Different products have different requirements for coating thickness. In the existing technology, the distance between coating rollers is usually fixed and it is difficult to adjust the distance. Therefore, it is impossible to accurately control the coating thickness according to the specific requirements of the product, resulting in the production of products that cannot meet the diverse market demands and reduce product quality.

A motor 2 is fixedly connected to the front end of the base 1. A connecting plate 8 is provided at the drive end of the motor 2. A toothed plate 7 is fixedly connected to the outer end of the connecting plate 8. Gears 6 are meshed with the outer walls of the toothed plates 7. The outer walls of the toothed plates 7 are slidably connected to both sides of the inner wall of the base 1. A main pulley 3 is fixedly connected to the outer end of the gears 6. A secondary pulley 4 is connected to the main pulley 3 through the inner diameter of the belt. The front end of the main pulley 3 is fixedly connected to the drive end of the motor 2. A transmission rod 5 is fixedly connected to the inner end of the secondary pulley 4. The outer wall of the transmission rod 5 is rotatably connected to the inner wall of the base 1 to drive the coating rollers 14 on both sides to adjust the spacing.

[0027] Specifically, a controller is installed at the front end of the base 1. The controller is electrically connected to motor 1 2, motor 2 9 and the motor. The upper coating roller 14 is a back roller. By driving the coating rollers 14 on both sides to rise and fall, the distance between the coating rollers 14 on both sides can be easily adjusted, thereby effectively controlling the amount of paint used and the thickness of the coating, ensuring that the coating thickness meets the precise specifications of the product, and improving the performance, stability and quality of the product.

[0028] Reference Figures 4-6As shown, a rotating cylinder 10 is rotatably connected to one end of the connecting plate 8. A pull plate 11 is slidably connected to the inner wall of the rotating cylinder 10. A coating roller 14 is provided at the bottom end of the pull plate 11. A motor 9 is fixedly connected to the inner wall of the front connecting plate 8. The drive end of the motor 9 is fixedly connected to the front end of the front rotating cylinder 10. A rotating roller 16 is sleeved on the left side of the inner wall of the base 1. A take-up roller 17 is sleeved on the right side of the inner wall of the base 1. The buckle assembly includes a buckle block 12 fixedly connected to the bottom end of the pull plate 11. The front and rear ends of the coating roller 14 are provided with slots 15. The outer wall of the buckle block 12 is provided on the inner wall of the slot 15. The shape of the buckle block 12 fits the slot 15. A spring 13 is fixedly connected to one end of the buckle block 12. The other end of the spring 13 is fixedly connected to the inner wall of the rotating cylinder 10 for the assembly and disassembly of the coating roller 14. A motor is fixedly connected to the rear end of the base 1. The rear end of the take-up roller 17 is detachably connected to the drive end of the motor.

[0029] Specifically, during installation, first pull the pull plate 11, then place the coating roller 14 into the rotating cylinder 10. After installation, release the pull plate 11, and the spring 13 will engage the locking block 12 into the locking groove 15 to complete the installation. Secondly, grooves are provided on the outer wall of the rotating cylinder 10, and the length of the grooves is equal to the length of the pull plate 11. Thirdly, during disassembly, the motor 2 9 needs to be controlled to rotate the rotating cylinder 10, extending the pull plate 11 to one side. The detachable design makes it easy to disassemble and assemble the coating rollers 14 on both sides. During use, coating rollers 14 will accumulate paint residue and impurities. Regular disassembly and cleaning can ensure the surface cleanliness of the coating rollers 14 and improve the coating quality.

[0030] Working principle: First, the controller starts motor 2, which drives the front main pulley 3 to rotate. The main pulley 3 drives the auxiliary pulley 4 to rotate via a belt, which in turn drives the transmission rod 5 to rotate. The transmission rod 5 drives the rear auxiliary pulley 4 to rotate synchronously and in the same direction as the main pulley 3. The main pulley 3 drives the gears 6 on both sides to rotate synchronously. The gears 6 drive the toothed plates 7 on both sides to rise and fall, and also drive the connecting plates 8 on the upper and lower sides and the coating roller 14 to rise and fall, adjusting the distance between the coating rollers 14. After adjustment, the rotating roller 16 is installed in the base 1, and... The material passes through the guide rollers on both the upper and lower sides, and through the middle of the coating roller 14, and is installed on the outer wall of the take-up roller 17. Then, the controller starts the motor and motor 9. The motor drives the take-up roller 17 to rotate. Then, motor 9 drives the upper coating roller 14 to rotate counterclockwise and the lower coating roller 14 to rotate clockwise, thus processing the outer wall of the material. When it is necessary to disassemble the coating roller 14, simply pull the pull plate 11. The pull plate 11 drives the locking block 12 to move and remove the locking block 12 from the locking groove 15, so that the upper and lower coating rollers 14 can be disassembled.
