Description

TECHNICAL FIELD

[0001] The utility model relates to medical production equipment technical field especially relates to a kind of high-speed roller plate aluminium-plastic blister packaging machine. BACKGROUND

[0002] Blister packaging machine is a kind of equipment that medical supplies are packaged in blister, wherein blister generally includes blister holder and aluminum foil sealed on blister holder. And blister holder is generally obtained by hot-pressing molding of PVC belt, and blister holder is provided with a plurality of bubble eyes, which are used to load medicines or medical herbs. In order to facilitate continuous production, the current blister production generally adopts continuous production mode, that is, after the goods are placed in the blister, they need to be packaged by blister heat sealing device, then pulled out by heat sealing traction device, and then punched by punching equipment to obtain single independent packaging product.

[0003] The current punching equipment basically adopts up-down opening and closing die to punch, for example, the high-speed blister packaging machine disclosed in the patent with publication number CN114671091A. The punching concave die in the packaging machine is connected to the die holder plate, the die holder plate is connected to the lower end of the lifting guide column, and the lifting guide column is slidably arranged on the mounting frame. In fact, the blister that has been formed is punched by the punching concave die that can be lifted and the punching convex die that is fixedly arranged. However, the whole punching structure is relatively complex, and the punching convex die is used in a single punching mode, which presses the blister from bottom to top on the punching convex die. Therefore, the lower end of the punching convex die needs to be tightly attached to the upper surface of the blister in the actual punching process. However, the protruding structure design will affect the transportation of the whole blister, and the formed blister is in the form of a strip, which will shake up and down during transportation, causing friction with the upper surface of the blister. The punching convex die may scratch the aluminum foil or sealing film on the blister. Therefore, such structure design needs to strictly control the tightness of the transportation of the formed blister, and also needs to set the distance between the punching convex die and the blister strip to avoid the punching concave die that can be lifted from breaking the blister strip when cooperating with the punching convex die.
