Film-drawing loading equipment for sandwiched film of automobile front windshield

Abstract

The invention relates to film-drawing loading equipment for a sandwiched film of an automobile front windshield. The film-drawing loading equipment comprises a film loading rack used for placing a film roll, a film transmission driving device, and a film releasing driving device, wherein the film transmission driving device is connected with the film loading rack and used for diving a film to move to a heating formation device; the film releasing driving device is arranged between the film loading rack and the film transmission driving device and is used for automatically releasing the film roll after the film roll is used up, so as to connect the film roll with a latter film roll. Compared with the prior art, as the film releasing driving device can release the former film roll after the former film roll is used up automatically instead of manual film releasing, the labor intensity of an operator is reduced.

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 indispensable, wherein Chinese patent CN 104210120 A discloses a film-drawing process for an automobile glass sound-insulating film, which includes the following steps: a, flattening: eliminating the folding 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 da...

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.
