Automatic blister packaging machine

Abstract

The invention belongs to the technical field of packaging equipment, and particularly discloses an automatic blister packaging machine. A blister suction roller die comprises a main shaft, a blister forming roller and a first driving mechanism driving the main shaft to rotate; the main shaft is coaxially connected with the blister forming roller; the main shaft is provided with a water inlet channel; the water inlet channel is communicated with a sealing cavity in the blister forming roller; a drain pipe connected with the cavity is inserted into the water inlet channel and is communicated with an outlet of a rotary joint; the water inlet channel is communicated with an inlet of the rotary joint; the blister forming roller is provided with a plurality of rows of blister pits at equal intervals in the circumferential direction of the blister forming roller; each row of blister pits are evenly distributed at equal intervals in the axial direction of the blister forming roller; each row of blister pits corresponds to an air suction channel; the air suction channels communicate with micropores of all the blister pits in the same row; a cover body covering one part of the outer circular surface of the blister forming roller is included; a channel is arranged between the outer circular surface of the blister forming roller and the cover body; and a heating source is arranged in the cover body. The device realizes integration, so that the occupied space is reduced, and the problem of a poor blister suction effect is solved.

Description

technical field [0001] The invention relates to the technical field of packaging equipment, in particular to an automatic blister packaging machine. Background technique [0002] The blister packaging machine is mainly suitable for the blister-type aluminum-plastic packaging of capsules, tablets and other items of various specifications in pharmaceutical factories, hospitals, food, electronics and other industries. The blister plates that are sent into the heater, forming device, positive pressure forming, and formed continue to advance and enter the feeding part. The feeder or high-speed vibrating feeder fills the plastic blisters with medicines or capsules, and the filled blister plates Before entering the rolling heat sealing, the aluminum foil is fed by the aluminum foil conveying mechanism to cover the blister plate, and then the plastic blister plate and the aluminum foil enter the rolling heat sealing device to heat and roll to seal, and then enter the batch number ma...

AI Technical Summary

Problems solved by technology

[0004] 1) The cooling device, blister forming roller and heating roller are designed separately, resulting in a large volume of the whole equipment and occupying a lot of space;

[0005] 2) In actual use, since the blister forming roller and the heating roller are in line contact, the heating area of ​​the PVC plastic hard board between the two is small, and there is not enough heating time, which may easily lead to uneven heating and bubble absorption poor effect;

[0006] 3) Since the cooling device and the blister forming roller are designed separately, there is a certain distance between the two, resulting in that the formed blister cannot be cooled in time, and the residual heat of the blister itself may easily cause the blister to detach from the blister forming roller post-deformation
