Forming mechanism of blister packaging machine

Abstract

The invention discloses a forming mechanism of a blister packaging machine, which comprises an upper forming die and a lower forming die. The lower forming die is installed on a forming frame, and is characterized in that a rotatable transmission shaft , the crankshaft is arranged on the transmission shaft, and the eccentric wheel installed on the transmission shaft, the eccentric wheel is in contact with the roller fixed on the frame of the forming mechanism of the blister packaging machine, and the crankshaft passes through the shaft sleeve It is connected with the mobile frame, and the mobile frame is connected with the bag box, and the bag box is composed of a fixed upper box body and a slidable lower box body, and an air bag is arranged in the bag box, and the lower box body and the upper box body Mold connection. The structure of the present invention utilizes the structure of the crankshaft and the eccentric wheel to make the state of the packaging mold stable and not easy to jump when the mold is opened and closed, and the structure of the airbag can be used to form the blister stably, and its reliability is high , ideal for blister molding.

Description

technical field [0001] The invention relates to a pharmaceutical machine, in particular to a blister forming mechanism of a blister packaging machine. Background technique [0002] Blister packaging machine is to soften the forming mold by the heating device, and use compressed air to blow the softened film into a blister in the forming device. The filling device will fill the packaged material into the blister, and then send it to the sealing device. The cover film is sealed with the forming die under the appropriate temperature and pressure drop, and finally the punching device punches it into the specified size, and then it becomes a blister packaging product. At present, during the mold opening and closing process of this blister packaging machine, a cam structure is used to drive the upper mold or the lower mold to move. Checking the Chinese patent database, the publication number is CN109466051A, and the name is "a blister forming device for a blister forming machine"...

AI Technical Summary

Problems solved by technology

In the process of using the cam structure to move the upper and lower dies, it is easy to cause the jumping of the upper die and the lower die, which affects the quality of the blister forming

In the forming mechanism of the above-mentioned blister packaging machine, the upper mold or the lower mold are equipped with springs as a buffer return mechanism. During the long-term use of the equipment, the spring will also affect the forming of the blister due to fatigue. quality
