Description

Technical Field

[0001] The utility model relates to the technical field of blister machines, in particular to a lifting device for taking and placing moulds. Background Art

[0002] The blister machine, also known as the thermoplastic forming machine, is a machine that blister-forms heated and plasticized thermoplastic plastic coils such as PVC, PE, PP, PET, HIPS, etc. into various shapes of advanced packaging decoration boxes, frames and other products. Using the vacuum suction generated by the vacuum pump, the heated and softened thermoplastic plastic sheets such as PVC and PET are blister-formed into various shapes of vacuum covers, blister trays, blister shells, etc. through molds. The main structure of the machine is composed of feeding, pulling, upper and lower electric heating furnaces, lower gate, multi-functional adjustable size, lower mold plate, upper mold, upper gate, knife gate, slicing, unloading and equipped with vacuum devices.
