Description

a corona machine

technical field

The utility model relates to a corona machine, in particular to a corona machine applicable to casting film equipment.

Background technique

The corona machine equipped for the high-speed cast film production line is often a single high-power generator, and the corona roller is also a steel core rubber-coated roller with a large diameter, and the moment of inertia is very large, which requires that the corona roller must have It has an independent traction power, and it needs to be paired with a pressure roller to form a traction force on the workpiece.

Since the casting film equipment is a wide-width equipment, the traction force formed by the pressure roller and the traction roller in the entire width range is easy to be inconsistent. On the one hand, it will cause stretching and deformation of the film surface of the casting film; If the part is not pressed tightly, air will enter between the film surface and the corona roller and be broken down by the high-voltage arc, forming a reverse corona. Facing this industry problem, we urgently need to solve the above two problems: 1. The film surface of the cast film needs to be effectively unfolded before entering the corona roller; 2. How to make the film close to the corona roller during the corona process to prevent air was brought in.

Utility model content

In order to solve the above problems, the purpose of this utility model is to provide a corona machine with simple structure, which can effectively expand the film surface of the casting film and prevent air from being brought into the space between the film surface and the corona roller.

The technical scheme that the utility model adopts for solving its technical problem is:

A corona machine, comprising a corona machine main body, the front and rear sides of the upper middle part of the corona machine main body are respectively provided with a front traction roller for pulling the workpiece to move and a first corona roller for corona treatment of the workpiece, the Between the front traction roller and the first corona roller, there are two spreading rollers respectively installed on the two side plates of the corona machine main body. On the second corona roller, a rear traction roller for pulling the workpiece to move is arranged under the second corona roller, and the rear traction roller is installed on the main body of the corona machine.

As an improvement of the above technical solution, a front guide wheel installed on the main body of the corona machine is arranged between the first corona roller and the spreading roller, and the level of the front guiding wheel is the same as that of the spreading roller. same, while the level of the first corona roller is lower than that of the front guide roller.

As a further improvement of the above technical solution, the second corona roller is arranged directly below the first corona roller, and a The middle guide wheel on the main body of the motion sickness machine, the middle guide wheel and the first corona roller are vertically staggered.

Here, a rear guide wheel installed on the main body of the corona machine is arranged between the second corona roller and the rear traction roller, and the second corona roller and the rear traction roller are simultaneously located on the side of the rear guide wheel. same side.

The beneficial effects of the utility model are: because the utility model is provided with two unfolding rollers respectively installed on the two side plates of the main body of the corona machine before the first corona roller, the workpiece can be effectively carried out by the two unfolding rollers. Horizontal expansion prevents wide workpieces from being stretched and deformed, and is applicable to workpieces of different widths; at the same time, the utility model is also equipped with front traction rollers and rear traction rollers at the front and back of the first corona roller and the second corona roller. The workpiece is pulled by the front traction roller and the rear traction roller, so that when the workpiece enters the first corona roller and the second corona roller, a stable tension is formed on the web of the workpiece and it is close to the first corona roller and the second corona roller. The roller surface of the second corona roller prevents air from entering between the workpiece web and the first corona roller or the second corona roller, effectively prevents the reverse corona, and improves the corona stability of the corona machine of the present invention; In addition, the utility model uses the first corona roller and the second corona roller for corona treatment, so the power of a single corona roller does not need to be set too high, thereby greatly extending the surface of the corona roller, the corona electrode and the corona roller. generator lifespan.
