Bubble cap packaging machine is a type of machinery used for processing drugs, especially for processing capsule drugs. There are mainly three types, including roller type bubble cap packaging machine, flat plate bubble cap packaging machine, and roller plate type bubble cap packaging machine. Their working principles are basically consistent, which is to seal inside the bubble cap under suitable temperature conditions. So, what is the process flow?

The process flow of bubble wrap packaging machine:

1. Bubble wrap packaging machine is a multifunctional packaging machine, where each packaging process is carried out at different workstations.

There are several film conveying mechanisms installed on the packaging machine, which are used to transport the film and pass it through the above-mentioned workstations to complete the blister packaging process.

The conveying mechanisms used in bubble wrap packaging machines include groove wheel mechanisms, cam rocker mechanisms, cam indexing mechanisms, ratchet mechanisms, etc., which can be selected based on the accuracy of the conveying position, acceleration curve, and adaptability of the packaging material.

2. Heating the formed film to a temperature suitable for thermoforming processing, which is determined based on the selected packaging material. For hard PVC, the temperature range for easy molding is 110-130 ℃. The PVC film within this range has sufficient thermal strength and elongation.

The temperature has an impact on the hot forming processing effect and the ductility of packaging materials, so it is required to control the temperature quite accurately.

However, it should be noted that the temperature referred to here is the actual temperature of the PVC film, which is directly measured on the surface of the film using a thermometer.
