Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical packaging technology, and in particular relates to an aluminum foil slitting device for pharmaceutical packaging. Background Technology

[0002] Aluminum foil, used in pharmaceutical packaging, is a metallic material made from rolled pure aluminum. Its core characteristics lie in its excellent barrier properties and chemical stability. With a thickness of 0.02 mm or more, aluminum foil effectively blocks the penetration of light, moisture, and oxygen, providing triple protection against moisture, light, and oxidation. Its smooth and dense surface structure prevents reactions between pharmaceutical ingredients and packaging materials, playing a crucial protective role, especially for active ingredients such as antibiotics and vitamins that are susceptible to environmental influences. The chemical inertness of aluminum foil allows it to withstand most pharmaceutical components, preventing migration and contamination. It also possesses excellent heat resistance (melting point up to 660℃), meeting the requirements of high-temperature sterilization processes. Furthermore, its mechanical strength can withstand compression during transportation, and combined with composite layer designs (such as polyethylene liners), it further enhances flexibility and sealing, making it a fundamental material in pharmaceutical packaging that balances functionality and safety.

[0003] Comparing with Chinese Patent CN212331165U9, a cutting device for aluminum foil used in pharmaceutical packaging is disclosed. The device includes a base, a gantry frame mounted on the base, and a vertically oriented guide cylinder fixedly mounted on the crossbeam of the gantry frame. An upper blade holder is fixedly connected below the piston connecting plate of the guide cylinder, and an upper cutting blade is mounted on the upper blade holder. A lower blade holder is mounted on the base, and a lower cutting blade is mounted on the lower blade holder. Both the upper and lower cutting blades have wedge-shaped cutting edges. The wedge-shaped cutting edge of the upper cutting blade faces the aluminum foil discharge direction, and the wedge-shaped cutting edge of the lower cutting blade faces the aluminum foil feed direction. The backs of the upper and lower cutting blades face each other. When the cutting device is not in operation, the upper and lower cutting blades are vertically separated by a certain distance. During cutting, the backs of the upper and lower cutting blades are in parallel contact. The structure is robust and stable, and the cut edges are neat after cutting.

[0004] However, the aforementioned patent requires the cutter to move up and down repeatedly and wait for the aluminum foil to pass through, which greatly prolongs the auxiliary pause time and seriously reduces the consistency and continuity of the slitting. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide an aluminum foil slitting device for pharmaceutical packaging to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pharmaceutical packaging aluminum foil slitting device includes a frame base plate, a frame body disposed in the middle of the frame base plate, an infeed / outfeed assembly disposed on one side of the frame body, a waste collection assembly disposed on the side of the frame body away from the infeed / outfeed assembly for collecting rotating and wound waste, and a cutting assembly for relative rotational slitting of aluminum foil mounted in the middle of the frame body. A discharge assembly for downward air jetting for unloading is disposed in the middle of the cutting assembly. The cutting assembly includes an upper rotating roller and a lower rotating roller mounted vertically along the frame body. The upper and lower rotary rollers are hollow circular rollers. Their rear ends are connected by a transmission gear set and rotate synchronously. A first motor is provided at the front end of the upper rotary roller. Several slitting punches are evenly distributed on the surface of the upper rotary roller, and several slitting grooves are evenly distributed on the surface of the lower rotary roller. The slitting punches correspond one-to-one with the slitting grooves. The unloading assembly includes a vent hole at the bottom of the slitting groove and an air outlet box that is close to the bottom surface of the inner wall of the lower rotary roller. An air inlet pipe is provided on the air outlet box. The air inlet pipe passes through one end of the lower rotary roller and is connected by a bearing.

[0008] Furthermore, the bottom of the air outlet box is arc-shaped with the opening facing downwards, and a sealing ring is attached thereto.

[0009] Furthermore, three ventilation holes are evenly distributed along the length direction at the bottom of each of the slitting grooves.

[0010] Furthermore: the lower rotary roller is symmetrically provided with limit flanges, and the upper rotary roller and the lower rotary roller are respectively connected to the bearing of the frame body.

[0011] Furthermore, the upper rotating roller is a solid circular roller.

[0012] Furthermore: the feeding and discharging assembly includes a first bracket fixedly mounted on the base plate of the frame, a feeding tray horizontally mounted in the middle of the first bracket, and a discharging guide plate mounted below the feeding tray, the discharging guide plate being inclined.

[0013] Furthermore: the feed tray is positioned between the upper and lower rotating rollers, and the discharge guide plate covers both sides of the lower rotating roller.

[0015] Compared with existing technologies, the beneficial effects are:

[0016] The machine employs symmetrically arranged upper and lower rotating rollers (the upper roller with a slitting punch and the lower roller with a slitting groove), which rotate synchronously via a transmission gear set. This ensures accurate alignment of the slitting punch and groove, effectively preventing misalignment or jamming and improving slitting quality, consistency, and continuity. An air vent and ventilation holes are installed inside the lower roller, automatically releasing compressed air when the slitting groove rotates to the bottom, blowing the medicine out of the groove for automatic unloading. This reduces manual intervention, prevents material adhesion or accumulation, and improves production efficiency. The components (feeding, unloading, slitting, unloading, and waste collection) are rationally arranged on the frame, maximizing space utilization. The machine has strong overall integrity, is suitable for continuous production lines, and is easy to maintain and operate. It achieves full automation of the slitting, unloading, and waste collection process for pharmaceutical aluminum foil packaging, offering advantages such as high precision, high efficiency, and high reliability, making it suitable for large-scale applications in the pharmaceutical packaging industry.
