Description

Technical Field

[0001] The utility model relates to the technical field of polyester film cutting, in particular to an equidistant cutting mechanism for polyester film production. Background Art

[0002] Polyester film, a film with polyester material as the base, is excellent as a base because polyester is flame retardant and has no stretch. Polyester film is a thermoplastic environmentally friendly plastic product. It is odorless and tasteless after burning, does not produce toxic gases, has high transparency, no water ripples on the surface, no crystal points, no direction or whitening, strong resistance to oil and chemicals, strong toughness and rigidity, and good impact resistance.

[0003] The equidistant cutting device is an important device in the production and processing of polyester film. In the Chinese utility model patent CN219235492U, an equidistant cutting mechanism for polyester film production is disclosed. The equidistant cutting mechanism for polyester film production cooperates with a threaded rod and two threaded blocks, so that the left and right threaded blocks drive two cutting blades to move relative to or away from each other. At this time, the spacing between the three cutting blades can be adjusted, thereby achieving the purpose of adjusting the cutting length, and improving the practicality of the mechanism. However, the fixed component at one end of the equidistant cutting mechanism for polyester film production is fixed, and there are still the following problems in use:

[0004] The fixed component of the equidistant cutting mechanism for producing polyester film cannot be adjusted in position, so that the distance between it and the outermost cutting blade cannot be adjusted. As a result, when one end of the polyester film is fixed and cut by the fixed component, the length of the polyester film between the outermost blade and the fixed component is different from the length cut between multiple blades, resulting in waste. Each processing will result in a section of waste, resulting in considerable waste. Utility Model Content
