Composite heat-sealing mechanism and roller-plate aluminum-plastic-aluminum blister packaging machine

Abstract

The invention provides a combined type heat sealing mechanism and a roller plate type aluminum plastic aluminum blister packaging machine. The combined-type heat sealing mechanism comprises a rolling heat sealing device, a motion conversion device and a plate type heat sealing device, wherein the rolling heat sealing device is arranged on a machine frame and continuously acts to be used for conducting heat sealing on blister plates and upper aluminum foils to form aluminum plastic packaging, the blister plates are conveyed from a conveying mechanism and filled with objects, the upper aluminum foils are conveyed from an upper aluminum foil roller, the motion conversion device is arranged on the machine frame, is located at the downstream position of the rolling heat sealing device and intermittently acts to be used for converting continuous conveying into intermittent conveying of the aluminum plastic packaging output by the rolling heat sealing device, the plate type heat sealing device is located at the downstream position of the motion conversion device and intermittently acts to be used for conducting heat sealing on the aluminum plastic packaging and an aluminum cover to form aluminum plastic aluminum packaging, the aluminum packaging is conveyed from the motion conversion device, and the aluminum cover is conveyed from an aluminum forming device. According to the combined type heat sealing mechanism, the continuous conveying mode can be converted into the intermittent conveying mode, heat sealing is more reliable, the requirement for coordination action among the devices is reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of pharmaceutical packaging, in particular to a composite heat-sealing mechanism and a roller plate type aluminum-plastic-aluminum blister packaging machine. Background technique [0002] With the continuous improvement of people's living standards, the requirements for pharmaceutical packaging are becoming more and more stringent, because it is directly related to people's health, and pharmaceutical packaging is extremely important for maintaining the performance of pharmaceuticals. The packaging materials that pharmaceutical companies choose to pack drugs are mainly determined by the properties of the drugs (moisture-proof, light-proof, flavor retention, etc.) and shelf life. Pharmaceutical packaging has developed from aluminum-plastic blister packaging and aluminum-aluminum blister packaging to aluminum-plastic-aluminum blister packaging. For the packaging of medicines (especially expensive medicines) that require...

Problems solved by technology

[0005] In the existing flat-type aluminum-plastic-aluminum blister packaging machine, according to the size of the final packaged plate, the PVC film roll, the feeder for filling the drug, the first heat-sealing device, the travel traction device, the second heat-sealing device, etc. Coordinated intermittent action is required, and the precision of the transmission mechanism is high; the PVC film needs to be heated and softened first, and then formed into a blister sheet on a flat plate by horizontal conveying, so the arrangement of the heating and softening parts and the blister forming parts The location is easy to cause burns to the surrounding staff, and the intermittent operation mode makes the work efficiency low; the first heat sealing device adopts flat heat sealing and intermittent action, which may easily cause the heat seal between the blister plate and the aluminum foil to be not tight
