Automatic high-speed vacuum blister forming machine

Abstract

The invention discloses an automatic high-speed vacuum blister forming machine, and relates to the field of blister forming equipment. According to the technical key points, the automatic high-speed vacuum blister forming machine comprises a blister forming machine body and a feeding device, wherein the feeding device comprises a placing frame, and a material roller with a plastic sheet wound around is rotationally connected on the placing frame; one end, close to the blister forming machine body, of the placing frame is rotationally connected with an upper pressing roller and a lower pressingroller, wherein a placing plate is horizontally arranged on the side, facing the lower pressing roller, of the material roller, the placing plate is arranged in the axial direction of the material roller, the upper surface of the placing plate is coplanar with the highest point of the surface of the lower pressing roller, and one end of the lower pressing roller is provided with a motor for driving the lower pressing roller to rotate; and the two ends, located on the placing plate, of the placing frame are correspondingly provided with finger air cylinders for clamping the plastic sheet, sliding rails are arranged on the placing frame in the moving direction of the plastic sheet, sliding blocks are slidably connected in the sliding rails, the sliding blocks are fixedly connected with cylinder bodies of the finger cylinders, and a driving device for driving the sliding blocks to move along the sliding rails are arranged on the placing frame. The automatic high-speed vacuum blister forming machine has the advantages of being high in roll changing efficiency and capable of reducing potential safety hazards.

Description

technical field [0001] The invention relates to the field of blister forming equipment, more specifically, it relates to an automatic high-speed vacuum blister forming machine. Background technique [0002] Blister molding is a kind of plastic processing technology. The main principle is to heat and soften the flat hard plastic sheet, then absorb it on the surface of the mold by vacuum, and form it after cooling. It is widely used in plastic packaging, lighting, advertising, decoration and other industries. Blister molding machine, also called thermoplastic molding machine, is a machine that absorbs heated and plasticized PVC, PE, PP, PET, HIPS and other thermoplastic coils into various shapes of advanced packaging and decoration boxes, frames and other products. Using the vacuum suction generated by the vacuum pump, the heated and softened thermoplastic sheets such as PVC and PET are molded into various shapes of vacuum covers, blister trays, blisters, etc. through molds. ...
