Technical Field

[0001] The utility model relates to the technical field of film treatment technology, in particular to sheet material corona treatment equipment for a film blowing machine. Background Art

[0002] The background technology of sheet corona treatment equipment for film blowing machines mainly comes from the demand for improving the surface properties of substrates such as plastic films. During the production and processing of plastic films, it is often necessary to treat their surfaces to improve their adhesion, wettability and printing adaptability. Traditional surface treatment methods often have problems such as uneven treatment effects, high energy consumption, and environmental pollution. Therefore, corona treatment technology, as a new surface treatment method, has gradually attracted people's attention and application.

[0003] The prior art also has the following defects during use:

[0004] 1. Before the corona treatment, the entire plastic film cannot be smoothly placed into the corona treatment device. If the plastic film is not smooth enough, the corona treatment will not be complete, which will affect the efficiency of the corona treatment.

[0005] 2. Before the corona treatment, the temperature of the film of the corona equipment in the prior art may be too high. Excessive temperature may cause the plastic film to shrink and deform to a certain extent, affecting the subsequent corona treatment. In addition, the surface of the plastic film may be contaminated with various dusts. Excessive dust accumulation on the surface of the plastic film may also affect the subsequent corona treatment.

[0006] In view of this, we propose a sheet corona treatment device for film blowing machines to solve the existing problems. Utility Model Content
