Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical aluminum foil packaging and cutting, in particular to a pharmaceutical aluminum foil packaging and cutting device. Background Art

[0002] In the process of pharmaceutical production, in order to effectively isolate oxygen and reduce the risk of drug oxidation, it is necessary to thermally press and seal an aluminum foil film with a capsule shell containing tablets. After packaging and plastic sealing, the aluminum foil needs to be cut. The pharmaceutical packaging aluminum foil film needs to be cut after packaging and plastic sealing.

[0003] A Chinese patent with the publication number CN212331165U discloses an aluminum foil cutting device for pharmaceutical packaging, including a base. A gantry is arranged on the base, and a vertically oriented guiding cylinder is fixedly arranged on the crossbeam of the gantry. A piston connecting plate of the guiding cylinder is fixedly connected below with an upper knife seat, and an upper cutting knife is installed on the upper knife seat. A lower knife seat is arranged on the base, and a lower cutting knife is installed on the lower knife seat. The cutting edges of both the upper cutting knife and the lower cutting knife are wedge-shaped. The wedge-shaped cutting edge of the upper cutting knife faces the aluminum foil discharging direction, and the wedge-shaped cutting edge of the lower cutting knife faces the aluminum foil feeding direction. The structure of the utility model is firm and stable, and the cut edge is neat after cutting.

[0004] Since the blades will become dull or damaged after long-term use and need to be replaced, in the existing aluminum foil packaging and cutting device, when replacing the blades, the machine needs to be stopped for replacement, and the replacement steps are relatively complex, with a long stop time, so the blades cannot be replaced quickly and timely, greatly reducing the production efficiency. Moreover, in the existing pharmaceutical cutting device, due to the absence of a knife sharpening mechanism, the blades will become blunt due to wear after long-term use, resulting in an uneven cutting surface of the aluminum foil and even possible burrs or tearing phenomena, thus affecting the packaging quality of the medicine. Therefore, a pharmaceutical aluminum foil packaging and cutting device is proposed for the above problems. Summary of the Utility Model

[0027] Working principle: Since the blade will become blunt or damaged after long-term use, the blade needs to be replaced. For the existing aluminum foil encapsulation cutting device, when replacing the blade, the machine needs to be stopped, and the replacement steps are relatively complex, with a long stop time, so the blade cannot be replaced quickly and in a timely manner, greatly reducing the production efficiency. Moreover, for the existing drug cutting device, since there is no knife sharpening mechanism, after long-term use, the blade will become dull due to wear, resulting in an uneven cutting surface of the aluminum foil, and even burrs or tearing may occur, thus affecting the encapsulation quality of the drug. Therefore, a drug aluminum foil encapsulation cutting device is proposed to solve the above problems. Since the blade will become blunt or damaged after long-term use and needs to be replaced, when replacing the blade, start the first motor 6 to drive the cutting knife 8 to rotate by the rotating column 7, so that the cutting knife 8 can be quickly and timely replaced, and the operation is simple and convenient, and the replacement of the cutting knife 8 can be completed without stopping the machine, greatly improving the production efficiency. After the drug encapsulation is completed, the aluminum foil needs to be cut. When cutting, start the first pneumatic cylinder 3 to drive the first pneumatic rod to drive the connecting frame 4 to move vertically downward, and then the cutting knife 8 also moves downward accordingly, so that the cutting of the aluminum foil can be completed. During the cutting process, under the action of the spring 14, the knife sharpening block 11 is always in close contact with the cutting knife 8, so that the surface of the cutting knife 8 can be ground. By setting the knife sharpening mechanism, the cutting knife 8 can be ground to maintain the sharpness of the blade, ensuring that the cutting surface of the aluminum foil is smooth and flat, not damaging the surface quality of the aluminum foil, improving the encapsulation quality, and at the same time being able to remove the wear and accumulated impurities on the blade, reducing the wear of the blade, reducing the frequency of blade replacement, reducing the maintenance cost, and improving the overall operation efficiency of the equipment.

[0028] During the encapsulation process of the drug, start the second motor 25 to drive the rotating rod to drive the aluminum foil roll 24 to rotate, so that the automatic feeding operation of the aluminum foil can be carried out. Start the third motor 27 to drive the conveyor roller to drive the conveyor belt 26 to rotate, so that the automatic conveying operation of the capsule shells can be carried out. At the same time, start the second pneumatic cylinder 21 to drive the second pneumatic rod 22 to drive the lifting block 19 to move vertically downward in the limit chute 18, and then the pressing roller 20 also moves downward accordingly until the pressing roller 20 moves vertically downward to thermally seal and bond the aluminum foil and the capsule shells containing the drug, thus completing the encapsulation operation of multiple drugs.
