Technical Field

The invention relates to a heating roller, which is applied to the die cutting industry, in particular to a heating roller device for removing bubbles.

Background

With the development of technology, the requirements of die-cutting parts used on mobile phones are higher and higher. The handle film is arranged on the adhesive surface on one side of the PI product with the two sides being coated with the adhesive, and the PI product is relatively thick and hard, so that bubbles always exist on the handle surface of the finished product. This is because, during the processing, when the die cutter is used for punching, the air will be blown to the adhesive region of the product by the cutter when the cutter is used for punching and lifting, and air bubbles are generated on the product (the air bubbles are located between the handle film and the double-sided adhesive tape). The bubbles affect the customer's assembly, so if bubbles are generated, the processed product is regarded as rejected, which greatly increases the production cost.

Disclosure of Invention

The present invention has been made to overcome the above-mentioned drawbacks of the prior art and an object of the present invention is to provide a heating roller apparatus for removing bubbles.

The purpose of the invention can be realized by the following technical scheme:

a heating roller device for removing bubbles, which comprises an upper roller shaft, a lower roller shaft, a roller shaft connecting mechanism, a distance adjusting mechanism, a fixing mechanism and a temperature controller,

the two ends of the upper roll shaft and the lower roll shaft are connected through the roll shaft connecting mechanism to form a roll shaft group with adjustable distance,

the distance adjusting mechanism is arranged in the roller shaft connecting mechanism in a penetrating way to adjust the distance between the upper roller shaft and the lower roller shaft,

the fixing mechanism is connected to the bottom of the roller shaft connecting mechanism,

and the temperature controller is connected with the lower roll shaft to adjust the temperature of the lower roll shaft.

The upper roll shaft is an aluminum roll shaft.

The lower roll shaft is a rubber roll shaft.

And an electric heating wire or a thermal resistor is arranged in the lower roll shaft.

The electric heating wire or the thermal resistor is connected with the temperature controller.

The roller shaft connecting mechanism consists of an upper roller shaft connecting mechanism and a lower roller shaft connecting mechanism, and through holes corresponding to the positions of the upper roller shaft connecting mechanism and the lower roller shaft connecting mechanism are formed in the middle of the upper roller shaft connecting mechanism and the lower roller shaft connecting mechanism.

The distance adjusting mechanism penetrates through the through hole, and the distance between the upper roller shaft connecting mechanism and the lower roller shaft connecting mechanism is adjusted through the rotating distance adjusting mechanism.

The inner wall of the through hole is tapped with an internal thread, and the distance adjusting mechanism is a long screw nut.

The fixing mechanism is provided with a sliding groove, and a connecting bolt is arranged in the sliding groove.

The temperature controller controls the surface temperature of the lower roll shaft to be 100-120 ℃.

Compared with the prior art, the invention is arranged on the laminating machine, the temperature of the heating roller is adjusted to be between 100 DEG and 120 DEG, the bearing film coated with the product passes through the heating roller, and the bubbles are lost through heat conduction. Because the main material PI of the product can resist the high temperature of more than 200 ℃, the passing time of the product is very short (instantaneous passing) when the product passes through the heating roller, the material characteristics of the product cannot be damaged, when the heating roller is not used, the produced product has bubbles, the reject ratio reaches more than 15%, the heating roller device is added to eliminate the bubbles on the product, the requirement of a client is met, and the yield of the product is improved.
