A film cutting device based on polymer material

Abstract

The invention discloses a thin film slitting device based on a macromolecule material. The thin film slitting device comprises an unwinding roll, an adjustable slitting mechanism and a winding roll, wherein the unwinding roll and the winding roll are respectively and rotationally connected with a bracket; the adjustable slitting mechanism is arranged between the unwinding roll and the winding roll, and is connected with electric telescopic rods which are symmetrically arranged at front side and back side; the adjustable slitting mechanism comprises a motor, fixed plates, slitting knives and aplurality of abutting plates; a rotary shaft is arranged between the two fixed plates; the multiple butting plates are arranged at the outer side of the rotary shaft along the circumference direction;the outer side of each abutting plate is clamped with the corresponding slitting knife. The thin film slitting device has the advantages that the design is novel; the adjusting rod is driven by an adjusting button to rotate, and drives a threaded sleeve cylinder to drive a sleeve ring to do face-to-face movement or opposite movement; in the face-to-face movement process of the sleeve ring, the abutting plates can be diffused; in the opposite movement process, the abutting plates can be approached, so as to adjust and replace the positions of the slitting knives, adjust the distance between the multiple slitting knives, and meet the different slitting width requirements.

Description

technical field [0001] The invention relates to the technical field of polymer material preparation equipment, in particular to a film cutting device based on polymer materials. Background technique [0002] Molecular materials are divided into natural polymer materials and synthetic polymer materials according to their sources; natural polymers are polymer substances that exist in animals, plants and organisms, and can be divided into natural fibers, natural resins, natural rubber, animal glue, etc. Synthetic polymer materials mainly refer to the three major synthetic materials of plastics, synthetic rubber and synthetic fibers, and also include adhesives, coatings and various functional polymer materials. Synthetic polymer materials have properties that natural polymer materials do not have or have superior properties - smaller density, higher mechanical properties, wear resistance, corrosion resistance, electrical insulation, etc. [0003] Among them, the aluminized film...

AI Technical Summary

Problems solved by technology

[0004] The pre-processing equipment used in the production of aluminized film, such as the film used for production and processing, is purchased from the manufacturer to the factory. Most of the film width is too wide and must be cut before use, otherwise it cannot meet different films. However, in the prior art, the device used to cut the width of the film cannot simultaneously cut films of different widths, and the cutting knife is inconvenient to adjust
