Multi-group connecting rod transverse forming punching mechanism and operation method for blister packaging machine

Abstract

The invention discloses a transverse forming blanking mechanism with multiple groups of connecting rods for a blister packaging machine. The transverse forming blanking mechanism comprises a pair of parallel guide columns, a driving device, sliding bearing and mounting seat assemblies, blanking performing members and a connecting rod mechanism, wherein the sliding bearing and mounting seat assemblies are freely slidably mounted on the pair of guide columns, the blanking performing members are disposed on the sliding bearing and mounting seat assemblies and used for performing transverse forming blanking on a material which waits for being subjected to blanking, and the connecting rod mechanism is composed of a pair of symmetrical driving connecting rods, a pair of symmetrical middle connecting rods and a pair of symmetrical rocking bars. According to the transverse forming blanking mechanism with the multiple groups of connecting rods for the blister packaging machine, the structure is compact, the mounting is simple and convenient, operation actions of the connecting rods are reliable, the service life is long, and requirements of large blanking pressure, long moving distance and high moving speed in terms of the transverse forming blanking mechanism for the blister packaging machine can be fully met.

Description

technical field [0001] The invention relates to a multi-group connecting rod transverse forming punching mechanism for a blister packaging machine, in particular to a multi-group connecting rod transverse forming punching mechanism for a blister packaging machine for hard film packaging under the deep drawing continuous forming working condition mechanism. The invention also relates to the operation method of the multi-group connecting rod transverse forming punching mechanism of the blister packaging machine. Background technique [0002] The blister packaging machine is a machine that forms a blister from a plastic film or sheet, and seals the product between the blister and the cover by heat sealing or bonding. [0003] Compared with soft film blister packaging, hard sheet blister packaging requires rounded corners around the package to prevent sticking. At present, the conventional fillet processing methods include the use of a complete set of punching dies and the tra...

AI Technical Summary

Problems solved by technology

However, after the hard film packaging base material is cut off, the load at the end of the oil cylinder disappears instantly, causing the oil cylinder to advance rapidly until it hits the cylinder, which has an impact on the entire equipment (in the process of using the original pressure breaking method, the cutter head is still connected to the pressure plate at the moment of pressure breaking. contact, the load does not disappear)

Therefore, the existing gas-liquid booster system is not suitable for punching, and a new booster mechanism is needed to drive the punching die to complete the slitting and overcome the impact on the entire equipment due to the instantaneous disappearance of the load.

Moreover, the packaging box of the blister packaging machine may have a large depth dimension after plastic heating, that is, deep drawing. In order to ensure that the packaging box can move over the punching die after cutting, the punching die must have a large upper and lower Moving distance
