Plastic film cooling solidification device

Abstract

The invention discloses a plastic film cooling solidification device. The plastic film cooling solidification device comprises a shell frame and a rotary shaft rod. The plastic film cooling solidification device is characterized in that contrate gears are disposed at the two ends of the rotary shaft rod correspondingly; lead screw gears are engaged with the contrate gears; lead screws are connected into the lead screw gears through screw threads; the lead screws at the two ends are connected with each other through at least one fixing rod; and each fixing rod is sleeved with a cooling roller.The lead screw gears are engaged with the contrite gears to drive the lead screws in the lead screw gears to perform parallel reciprocating movement, so that plastic film winded on the cooling rollersis subjected to cold drawing, the hardness of the plastic film is improved, the thickness requirement of the certain specification can be met, the cooling solidification device is additionally arranged on the back of a plate roller of equipment, the PET coating film is guided into the cooling solidification device immediately after PET coating film is subjected to high-temperature embossing, thePET coating film is rapidly transformed into cold-state solidification from the hot state, the flatness of the surface of the film is good, shrinkage is small, deformation does not occur, thus the product quality is improved, and loss is reduced.

Description

technical field [0001] The invention relates to the field of laser film production, in particular to a plastic film cooling and shaping device. Background technique [0002] Films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins are used for packaging and as lamination layers, plastic packaging and plastic packaging products account for an increasing share of the market, In particular, composite plastic flexible packaging has been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging, quick-frozen food packaging, cooking food packaging, fast food packaging, etc. These products give People's lives have brought great convenience. During the production process of plastic film, the molten plastic melt is extruded from the mold to form a plastic film (a film bubble is formed when it is extruded from the mold of the blow molding machine, and the fil...

AI Technical Summary

Problems solved by technology

During the production process of plastic film, the molten plastic melt is extruded from the mold to form a plastic film (a film bubble is formed when it is extruded from the mold of the blow molding machine, and the film bubble is further inflated to form a film), and the film is solidified after cooling. Finally, it is rewound by the winding shaft. The existing cooling effect is not very ideal, resulting in poor film quality, low elongation, and low strength. During the production process of the molding machine, the PET coating film is rolled by a high temperature plate at 170 degrees After flowering, the stroke with the cooling and setting roller is too long, the shrinkage of the finished film is too large, the deformation is serious, and the quality requirements of the product cannot be met
