[0001] This invention relates to the field of alcohol-resistant thermosensitive film processing technology, specifically to a flattening and drying device and its control method for medical alcohol-resistant thermosensitive films. Background Technology

[0002] Alcohol-resistant thermal film is a special medical composite film material, mainly used for packaging medical supplies, especially for packaging alcohol-containing medical supplies, such as alcohol swabs. The flattening and drying device for alcohol-resistant thermal film is a special equipment for producing highly alcohol-resistant thermal paper.

[0003] The flattening and drying device for medical alcohol-resistant thermal film can achieve uniform coating, rapid drying and pressing of thermal paper, ultimately producing thermal paper with high alcohol resistance and high printing precision.

[0004] During the drying process of the alcohol-resistant heat-sensitive film after adhesive coating, if there is traction force on the movement of the alcohol-resistant heat-sensitive film, there is a problem that the alcohol-resistant heat-sensitive film will deform during the drying process.

The heating mechanism includes a second conveyor belt surface. The outer side of the second conveyor belt surface has an anti-slip groove, and the inner side of the second conveyor belt surface has a conductive ring groove. A conductive block is slidably connected to the inner side of the conductive ring groove, and the upper end of the conductive block is fixedly connected to a conductive rod. Both ends of the first and second conveyor belt surfaces are rotatably connected to transmission rollers, and one end of the transmission roller is fixedly connected to the main shaft of the first motor.

[0008] As a further optimization of the present invention, wherein: an electric heating wire is built into the second conveyor belt surface, and the electric heating wire built into the second conveyor belt surface is energized through a conductive block, and two conductive blocks and two conductive ring grooves are provided, and the conductive blocks and conductive ring grooves correspond one-to-one.

[0011] As a further optimization of the present invention, the support frame includes a frame body, a square hole is provided on the inner side of the upper end of the frame body, a positioning mechanism is slidably connected inside the square hole, a second limiting groove is provided on the inner side of the upper end of the square hole, and a telescopic spring and a damping telescopic rod are fixedly connected inside the second limiting groove.

[0012] As a further optimization of the present invention, the positioning mechanism includes a positioning block, and a first limiting groove is provided on the inner side of the upper end of the positioning block. The bottom of the first limiting groove is fixedly connected to the bottom of the telescopic spring and the damping telescopic rod, and the damping telescopic rod is installed inside the telescopic spring.

[0013] As a further optimization of the present invention, the positioning block has a cross-section of a cross shape, and a circular hole is provided in the middle of the positioning block for positioning the upper pressing roller.

[0017] S2: Entering the drying mechanism for drying: After pressing, the alcohol-thermal film enters the drying chamber. During this process, the alcohol-thermal film is conveyed through the first conveyor belt and the second conveyor belt. While being conveyed through the second conveyor belt, the heating wires inside the second conveyor belt can heat the bottom of the alcohol-thermal film, and the drying plate can heat the top of the alcohol-thermal film.

[0021] 1. In this invention, by setting a first conveyor belt surface and a second conveyor belt surface, during the drying process of the alcohol thermal film, by laying the alcohol thermal film flat on the upper part of the first conveyor belt surface and the second conveyor belt surface, the traction force on one side of the alcohol thermal film movement is effectively reduced, thereby avoiding the problem of deformation of the alcohol thermal film during the drying process and effectively improving the production quality of alcohol thermal film.

[0022] 2. In this invention, the alcohol-thermal film is cooled after drying to ensure its stability during the winding process, thus preventing the problem of stretching of the alcohol-thermal film due to the winding traction force when it is directly wound after drying.

[0023] 3. In this invention, the flattening and drying device is specially designed with a positioning mechanism and a support frame. By automatically positioning the upper and lower pressing rollers, stable processing of alcohol heat-sensitive films of different thicknesses is achieved. The cooperation of the power unit and the second motor provides a stable power source for the pressing and conveying process, ensuring the smooth conveying of the alcohol heat-sensitive film during processing. In addition, the anti-slip groove further improves the stability during the conveying process, prevents the film material from sliding and stretching, and ensures the quality of the final product.

During this process, the alcohol thermal film 9 is conveyed by the first conveyor belt surface 24 and the second conveyor belt surface 251. During the conveying process by the second conveyor belt surface 251, the heating wires installed inside the second conveyor belt surface 251 can heat the bottom of the alcohol thermal film 9, and the drying plate 23 can heat the top of the alcohol thermal film 9. During the heating process, the alcohol thermal film 9 is laid flat on the top of the second conveyor belt surface 251. This can evenly heat the pressed alcohol thermal film 9 and prevent the alcohol thermal film 9 from deforming due to the tension caused by winding or conveying during the heating process, further improving the stability of the alcohol thermal film 9 during the drying process.
