Principle of vacuum pump of blister machine:
The blister machine (also called the thermoforming machine) is a machine that sucks the heated plasticized PVC, PE, PP, PET, HIPS and other thermoplastic plastic coils into various shapes of advanced packaging boxes, frames and other products. Using the vacuum suction force generated by the vacuum pump, the heated and softened PVC, PET and other thermoplastic plastic sheets are blister-molded into various shapes of vacuum covers, blister trays, blisters, etc.
Vacuum equipment
The vacuum system consists of vacuum pumps, gas storage tanks, valves, pipelines and vacuum gauges. In vacuum forming, a separate vacuum pump is often used. The vacuum of this pump should reach 0.07~0.09 Mpa (520mmHg) or more. Gas storage tanks are generally cylindrical boxes welded with thin steel plates, with an oval bottom. The capacity of the gas storage tank should be at least half the capacity of the largest forming chamber. The vacuum pipeline must be equipped with appropriate valves to control the narrow vacuum capacity.
The rotating power of the vacuum pump is determined by the size of the molding equipment and the molding speed. Larger or faster equipment is usually as large as 2-4KW. The size of the vacuum central system depends on the specific production and development requirements of the factory.
