Description

Device for humidifying PVC (polyvinyl chloride) film

Technical Field

The invention belongs to the technical field of PVC (polyvinyl chloride) film production, and particularly relates to a device for humidifying a PVC film.

Background

In the PVC film processing process, the PVC film has high heat after being produced, so the PVC film is dry, and the PVC film can be automatically rolled up under the condition of drying the PVC film, so the produced PVC film is unqualified; similarly, the produced PVC film can also cause the PVC film to automatically curl when being stored if the PVC film is not effectively cooled, and the curling can directly cause the PVC film to be useless and can not be used. In order to overcome the above problems, a humidifying device has been proposed in the prior art, which humidifies the PVC film by means of a painting member absorbing water. However, under this kind of structure, the area of contact between PVC membrane and the piece of paining is little, and the humidification effect is relatively poor, and then makes the PVC membrane still appear the fold easily and can curl.

Disclosure of Invention

The invention provides a device for humidifying a PVC film, which has good cooling and humidifying effects and is used for overcoming the defects of the prior art.

In order to achieve the purpose, the invention adopts the following technical scheme: a device for humidifying a PVC film comprises a frame body, a humidifying mechanism arranged on the frame body and a driving piece for driving the humidifying mechanism to rotate; the humidifying mechanism comprises a rotating piece matched with the driving piece and an smearing piece used for humidifying the PVC film; still be equipped with on the support body and be used for leading the guide film roller that conveys to the PVC membrane, this guide film roller is located paint on the front side below position of piece.
