Hot air internal circulation type drying furnace for anti-static winding film with good tensile property

Abstract

The invention discloses a hot air internal circulation type drying furnace for an anti-static winding film with good tensile property. The hot air internal circulation type drying furnace comprises arack, a drying furnace body, a plurality of hot air inner circulation devices, a heater, a plurality of conveying roller cylinders, a film inlet roller and a film outlet roller, the drying furnace body is transversely arranged at the upper end of the rack; a drying cavity is formed in the drying furnace body, the left side and the right side of the drying furnace body are respectively provided with a membrane inlet and a membrane outlet, the membrane inlet and the membrane outlet are respectively communicated with the drying cavity, a film inlet roller cylinder capable of being matched with the drying furnace body is arranged at the position, close to the film inlet opening, of the side edge of the drying furnace body. According to the hot air internal circulation type drying furnace, thehot air inner circulation device is arranged in the drying furnace, the heater is arranged at the bottom of the drying furnace, the heater is used for heating ambient air, the hot air inner circulation device conveys hot air to the upper end of the conveying roller and circulate continuously, the hot air is repeatedly used, so that the heat loss is reduced, the energy is saved, the cost is reduced, and the drying efficiency is higher.

Description

【Technical field】 [0001] The invention relates to the technical field of protective film, in particular to the technical field of protective film glue drying furnace. 【Background technique】 [0002] According to the scope of application, the protective film can be applied in the following fields: the surface of metal products, the surface of coated metal products, the surface of plastic products, the surface of automobile products, the surface of electronic products, the surface of signage products, the surface of profile products, and the surface of other products. Functionally speaking, the protective film is to put a film on the physical objects we want to protect. Now there are functional protective films such as AR anti-reflective film, AG frosted anti-reflective film, mobile phone mirror film, anti-peeping film, high-definition anti-scratch film, etc. In the production process of the protective film, in order to improve the adhesion with the surface of the protected o...

AI Technical Summary

Problems solved by technology

In the production process of the protective film, in order to improve the adhesion with the surface of the protected object, glue is usually coated on one side of the protective film. After the glue is coated, the glue needs to be dried to a certain extent so that the glue can be firmly attached to the surface of the protective film. , to remove the fluidity of the glue while maintaining the viscosity of the glue, but the existing drying equipment consumes a lot of energy, and it needs to consume a lot of energy when drying, the cost is high, and it causes a certain amount of waste
