Oil-shield temperature automatic control apparatus

Abstract

The invention discloses an oil-shield temperature automatic control apparatus which includes a vacuum support, a vacuum sealing end surface and an adjustment guide rail which is arranged therebetween. An adjustment motor is installed on and is connected to one end, which passes through an end surface of the vacuum support, of the adjustment guide rail. An evaporator is arranged fixedly on the adjustment guide rail, wherein a heating bar is arranged in the evaporator. A plurality of spray nozzles and an integrated sensor are disposed on the evaporator. An electromagnetic valve is arranged on each spray nozzle. An oil-shield temperature automatic controller, which is connected to the heating bar and the integrated sensor, is disposed in the evaporator. The oil-shield temperature automatic controller can automatically set and detect oil film thickness and plating film linear velocity according to the requirement on the oil film thickness. When the oil film thickness and the plating film linear velocity of a plating layer are disqualified, the power of the heating bar in the evaporator can be adjusted automatically, so that oil-shield temperature can reach the requirement, and then the apparatus performs detection again until the oil film thickness and the plating film linear velocity are qualified. The apparatus ensures an excellent and uniform effect of the oil film and reduces oil pollution.

Description

technical field [0001] The invention relates to the technical field of vacuum coating technology, in particular to an automatic oil shielding temperature control device used on a vacuum winding coating machine, which can detect the thickness of the oil film on-line and automatically adjust the oil shielding temperature to make the shielding effect good. Background technique [0002] At present, the oil shielding device of vacuum coating is to spray oil vapor on the base film to form uncoated stripes before the base film is coated, so as to control the coating area of ​​the base film. The commonly used oil shielding device is fixed in the vacuum chamber of the vacuum coating device, which cannot be adjusted according to the position of the base film, nor can it control the spraying position of the oil vapor, which limits the scope of use of this system. In view of the above situation, the prior art can solve the technical defects of the above oil shielding device. However, t...

AI Technical Summary

Problems solved by technology

However, the technology that can detect the thickness of the oil layer on-line in the oil shielding device has not yet appeared, and the temperature of the shield cannot be adjusted, so that the shielding effect is not ideal, and there is a certain amount of oil pollution.
