[0002] Blister packaging machines are equipment that use transparent plastic films or sheets to form blister packs and seal products using methods such as heat sealing and bonding. They are widely used in the pharmaceutical industry for the production of tablets, capsules and other medicines, and include structures such as heating, forming, filling, heat sealing and die cutting.
[0003] The main function of the punching device is to cut the formed blister material (such as PVC, PVDC or aluminum foil) according to the preset shape and size, thereby completing the final forming of the blister packaging; it includes a power unit, a punch and a die. When the blister packaging material arrives at the punching station, the power unit applies strong pressure, causing the punch to move downward and cooperate with the die. Under the combined action of the punch and the die, the blister packaging material is sheared and separated.
[0004] The horizontal alignment of the punch and die is the key to achieving high-quality punching. If the punch is not horizontal, it may result in incomplete punching, excessive burrs, and affect the sealing and appearance of the packaging. However, existing punching equipment lacks a device to level the punch. Utility Model Content

[0018] like Figure 1 The blister packaging machine punching device shown includes: a mounting frame 1, a power unit 2, a mounting plate 3, a punch assembly, and a die assembly. The mounting frame 1 is used to install and support other components. Specifically, the inner top of the mounting frame 1 is connected to the power unit 2, and the inner bottom of the mounting frame 1 is connected to the bottom of the die assembly. The mounting frame 1, power unit 2, and die assembly can all be connected by detachable bolts, facilitating component replacement and maintenance. In this embodiment, the mounting frame 1 includes a top plate 1-1, a bottom plate 1-2, and a connecting plate 1-3. The top plate 1-1 is parallel to the bottom plate 1-2, and the top plate 1-1 and bottom plate 1-2 are connected by the connecting plate 1-3. The top plate 1-1, bottom plate 1-2, and connecting plate 1-3 can be integrally welded or connected by bolts. The bottom of the top plate 1-1 is connected to the power unit 2, and the upper part of the bottom plate 1-2 is connected to the die assembly.
[0019] The lower part of the power unit 2 is connected to the mounting plate 3. The mounting plate 3 has the punch assembly located below it, and the mounting plate 3 and the punch assembly are connected by a detachable leveling device. The leveling device is used to adjust the level of the punch assembly. The lower part of the punch assembly corresponds to the upper part of the die assembly. The power unit 2 provides force to drive the mounting plate 3 and the punch assembly to move up and down. When a downward force is provided, the punch assembly moves downward to cooperate with the die 11, cutting and separating the blister packaging material. The structure of the power unit 2 is not specifically limited; it can drive the mounting plate 3 to move up and down linearly, such as a cylinder or hydraulic cylinder.
[0020] To prevent the mounting plate 3 from shifting position during vertical movement, the device also includes multiple guide posts 6.
