In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0024] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0025] like Figures 1 to 5 The illustrated pharmaceutical aluminum foil printing and coating apparatus includes a support 1 for supporting the pharmaceutical aluminum foil printing and coating process. A conveyor frame 2 is connected to one side of the support 1. A conveyor belt 201 for conveying pharmaceutical aluminum foil is installed on the side of the conveyor frame 2. A hollow frame 3 and a support plate 4 are welded to the top of the conveyor frame 2. An irregularly shaped hollow column 303 is installed on the inner bottom wall of the hollow frame 3. A spring 304 is installed inside the irregularly shaped hollow column 303. One end of the spring 304 is connected to a limiting moving disk 305. A connecting block 302 is welded to the end of the limiting moving disk 305 away from the spring 304. A second motor 301 is installed on the side of the connecting block 302. The output shaft of the second motor 301 is connected to a cleaning wheel 306 for cleaning via a coupling. The coupling is a mechanical device used to connect two shafts (driving shaft and driven shaft) so that they rotate together and transmit torque. Its main function is to achieve reliable power transmission between the shafts of different components, while allowing a certain degree of axial, radial and angular displacement to compensate for shaft misalignment caused by factors such as manufacturing errors, installation errors, thermal expansion or component deformation.

[0026] The limiting moving plate 305 is slidably installed inside the irregular hollow column 303, and a pharmaceutical aluminum foil belt 5 is set above the conveyor belt 201. The pharmaceutical aluminum foil belt 5 is placed on the conveyor belt 201, and the conveyor belt 201 drives the pharmaceutical aluminum foil belt 5 to move towards the bracket 1. The second motor 301 is turned on, and the second motor 301 drives the cleaning wheel 306 to rotate in the opposite direction to the movement of the pharmaceutical aluminum foil belt 5. The cleaning wheel 306 contacts the surface of the pharmaceutical aluminum foil belt 5 and cleans the surface of the passing pharmaceutical aluminum foil belt 5. When encountering pharmaceutical aluminum foil belts 5 of different thicknesses, the contact pressure between the cleaning wheel 306 and the pharmaceutical aluminum foil belt 5 is automatically adjusted by the tension of the spring 304.

[0027] The side of the support plate 4 is provided with an air inlet 401, the inside of the air inlet 401 is provided with a fan 402, the side of the support plate 4 is communicated with a ventilation pipe 403, the inside of the ventilation pipe 403 is provided with a plurality of heat conduction plates 404, one of the heat conduction plates 404 is provided with a heating pipe 405 below for heating, a plurality of filter plates 406 for filtering are slidably installed on the vertical inner wall of the ventilation pipe 403, the bottom of the ventilation pipe 403 is provided with an air outlet 408, and the bottom of the ventilation pipe 403 is provided with a wind collector 407. When the fan 402 is started, the fan 402 sucks air from the air inlet 401 into the ventilation pipe 403, the heating pipe 405 heats the heat conduction plate 404, the air contacts the filter plate 406 through the holes on the surface of the heat conduction plate 404, the filter plate 406 filters and dries the hot air, and the filtered and dried air is discharged through the air outlet 408. Through the action of the wind collector 407, the hot air contacts the medicinal aluminum foil belt 5 to preheat the medicinal aluminum foil belt 5, and after a period of time, the filter plate 406 can be removed for replacement or cleaning.

[0028] The bracket 1 is provided with a first motor 101 on one side, and the output shaft of the first motor 101 is connected with a first roller 102 through a shaft coupling. The other side of the bracket 1 is connected with a second roller 103, a third roller 104 and a printing rubber roller 108. The printing rubber roller 108 works with the printing plate roller 107 to transfer ink and transfer the pattern on the printing plate roller 107 to the medicinal aluminum foil belt 5. The printing rubber roller 108 is usually made of materials with good elasticity and ink affinity, such as rubber. The hardness and elasticity need to be selected according to the material and thickness of the aluminum foil and the requirements of the printed pattern, so as to ensure that the ink can be uniformly transferred and the pattern can be clearly printed on the aluminum foil. The top of the bracket 1 is symmetrically provided with two telescopic rods 105, the movable parts of the two telescopic rods 105 are connected with a moving plate 106, the side of the moving plate 106 is connected with the printing plate roller 107, and the surface is engraved with concave or convex structure of the pattern or text to be printed. When the medicinal aluminum foil belt 5 passes between the printing plate roller 107 and the printing rubber roller 108, the ink will be transferred from the pattern part of the printing plate roller 107 to the medicinal aluminum foil belt 5. The manufacturing precision of the printing plate roller 107 is crucial to the printing quality, and factors such as pattern accuracy, hardness and wear resistance of the surface will directly affect the clarity and durability of the printing. The medicinal aluminum foil belt 5 is printed and coated by the action of the printing plate roller 107 and the printing rubber roller 108.
