Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum foil production technology, specifically to a pharmaceutical aluminum foil printing and coating machine. Background Technology
[0002] Aluminum foil is one of the most commonly used packaging materials for pharmaceuticals. Aluminum foil packaging has the characteristics of strong sealing, corrosion resistance and safety. In the process of processing aluminum foil, printing and coating machines are required.
[0003] For example, patent announcement number CN222291274U discloses a pharmaceutical aluminum foil printing and coating machine, including a fixed base. An unwinding device is fixedly connected to the left side of the top of the fixed base, and a printing device is fixedly connected to the left side of the top of the fixed base, located to the right of the unwinding device. A support rod is fixedly connected to the center of the top of the fixed base. This invention facilitates the unwinding of aluminum foil using the unwinding device, the printing process using the printing device, the winding of the produced aluminum foil using the winding device, the coating application using the spraying device, and the absorption of gas by the suction pipe using a hot air blower. The hot air is then heated by the hot air blower and discharged through the exhaust pipe and exhaust head, facilitating the drying of the aluminum foil. This effectively prevents the ink and protective coating on the aluminum foil surface from losing adhesion, thus avoiding paint and ink peeling off during the winding process.
[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:
[0005] Although this pharmaceutical aluminum foil printing and coating machine can effectively prevent the ink and protective coating on the aluminum foil surface from losing adhesion and causing the coating and ink to fall off during the winding process, during use, the first and second rubber rollers are needed to press and position the top and bottom of the aluminum foil during the hot air drying process. However, the area where the aluminum foil surface is in contact with the first rubber roller cannot be dried, resulting in uneven drying. Furthermore, the undried ink and protective coating are prone to adhering to the surface of the first rubber roller, causing contamination. Utility Model Content

[0028] As a technical optimization of this utility model, by setting up a heating mechanism 11, the fan 112 can be started to deliver air to the interior of the heating box 111. At this time, the heating wire 113 can be used to heat the air inside the heating box 111.
[0029] refer to Figure 3An air collection box 12 is fixedly installed on the top of the fixed plate 6. A heating box 111 is fixedly installed on the top of the air collection box 12.

[0034] As a technical optimization of this utility model, by setting a screw 17 and a limiting plate 18, the screw 17 can limit the limiting plate 18, and the limiting plate 18 can limit the pull plate 15, thereby preventing the pull plate 15 from moving when no one intervenes.
[0035] refer to Figure 3 A telescopic rod 19 is fixedly connected to the right side of the top of the heating box 111, and the other end of the telescopic rod 19 is fixedly connected to the right side of the top of the inner wall of the connecting frame 102.
[0036] As a technical optimization of this utility model, by setting a telescopic rod 19, the vertical movement of the connecting frame 102 can drive the telescopic rod 19 to extend and retract.

[0037] The working principle and usage process of this utility model are as follows: In use, the unwinding device 2, printing device 3, spraying device 4, and rewinding device 5 are existing technologies. The structures and working principles of the unwinding device 2, printing device 3, spraying device 4, and rewinding device 5 in the prior art (application number: 202421009222.5) are the same, and will not be repeated here. When printing on aluminum foil, the aluminum foil on the surface of the unwinding device 2 is first pulled and inserted into the inner side of the two printing rollers of the printing device 3. Then, the unwinding device 2 and the printing device 3 are started. The unwinding device 2 is used to transport the aluminum foil, and the printing device 3 is used to print on the aluminum foil. Then, the rewinding device 5 is started to rewind the printed aluminum foil onto the surface of the rewinding device 5. Simultaneously, the printed aluminum foil passes through the spraying device 4. At the bottom and top of the tension roller 9, the protective coating can be sprayed onto the surface of the aluminum foil by starting the spraying equipment 4. Then, by starting the fan 112 and the heating wire, the air supplied by the fan 112 into the heating box 111 can be heated and blown to the top of the tension roller 9 through the air collection box 12 and the ventilation pipe 13, thereby heating and drying the aluminum foil passing over the top of the tension roller 9. At the same time, by starting the electric push rod 103, the output end of the electric push rod 103 can drive the connecting frame 102 to move upward. The upward movement of the connecting frame 102 can drive the shaft 8 and the tension roller 9 to move upward, so that the user can use the tension roller 9 to adjust the tension of the aluminum foil, avoid wrinkles or loosening of the aluminum foil, and improve the uniformity of aluminum foil printing.
[0038] In summary, this pharmaceutical aluminum foil printing and coating machine, by setting up a fixed plate 6, a movable groove 7, a shaft 8, and a tension roller 9, utilizes the movable groove 7 to allow the fixed plate 6 to move and limit the shaft 8 and tension roller 9. By moving the shaft 8 up and down, the tension roller 9 can move up and down, thereby adjusting the tension of the aluminum foil passing over it. This solves the problem that in the hot air drying process of aluminum foil, it is necessary to use a first rubber wheel and a second rubber wheel to press and position the top and bottom of the aluminum foil. However, the area where the aluminum foil is in contact with the first rubber wheel cannot be dried, resulting in uneven drying. Furthermore, undried ink and protective coating are prone to adhere to the surface of the first rubber wheel, causing contamination.
