A film-drawing and film-loading device for an interlayer diaphragm of an automobile front windshield

Abstract

The invention relates to a film-drawing and film-loading device for an interlayer diaphragm of an automobile front windshield, comprising: a film-loading frame for placing a film roll; a diaphragm transmission drive device connected with the film-loading frame for driving the Film to heating forming device; film loosening drive device, located between the upper film frame and the film transmission drive device, used to automatically release the roll of film when the roll of film is used up, so as to carry out the forward and backward film roll Contact film. Compared with the prior art, the membrane loosening drive device of the present invention can automatically loosen a roll of membrane when the roll of membrane is about to be used up, without manual loosening of the membrane, reducing the labor intensity of operators.

Description

technical field [0001] The invention relates to the field of lamination of laminated glass, in particular to a film-drawing and film-loading device for an interlayer film of an automobile front windshield. Background technique [0002] my country's safety standards stipulate that automobile windshields must use laminated glass or tempered glass in some areas, and other windows should use tempered glass. Therefore, general ordinary glass and plexiglass are not suitable for automobile windshields. Therefore, for the front windshield of an automobile, an interlayer diaphragm is essential, wherein Chinese patent CN104210120A discloses a film-drawing process for an automobile glass sound-insulating film, which includes the following steps: a, flattening: eliminating the creases of the sound-insulating diaphragm; b. Evening: let the sound insulation diaphragm pass through the stretching roller smoothly; c. Humidity adjustment: prevent the sound insulation layer from being damaged...

AI Technical Summary

Problems solved by technology

However, it needs to manually loosen the film and connect the film during use. The clamping transmission drive has no servo control, and the clamping transmission roller does not have an automatic deviation correction function. During the use process, the operator needs to manually adjust the film transmission. location, and the time for film connection is relatively short, and it cannot automatically stop when the film is not connected in time. The time for changing parameters is short, and the film pulling operator is tired.
