Problems solved by technology

[0007] In the existing production process of film stretching, after the film is heated and stretched, it is pre-cooled with room temperature air by a pre-cooling axial fan, and then further cooled by a 5-horsepower cooling air conditioner. The temperature of the cooling air conditioner is 6-10°C. The cooling temperature of the diaphragm is high, and the temperature of the diaphragm after cooling is 18-25°C. After the diaphragm is cooled and cut, it will shrink by 150-300mm in the length direction and 20-80mm in the width direction. Relatively large, the diaphragm cannot be put into use immediately after cooling and cutting, and due to the cooling temperature of the diaphragm

Abstract

The invention relates to a glass film drawing cooling system, which is used for the production of interlayer film drawing of automobile front windshields, and includes a blowing cooling device and a mobile cooling table, and the blowing cooling device includes a forced cooling air conditioner , a conveyor belt and a cooling tuyere, the forced cooling air conditioner is connected to the cooling tuyere, the cooling tuyere is set opposite to the conveyor belt, and the conveyor belt is connected to a mobile cooling platform. Compared with the prior art, the present invention has the advantages of double air cooling, convenient guide adjustment, convenient and fast movement, stable transmission position and the like.

Description

technical field [0001] The invention relates to the field of laminated glass lamination, in particular to a cooling system for drawing a glass film. Background technique [0002] The principle of automatic film-drawing cooling of the interlayer diaphragm: the automatic film-drawing cooling of the interlayer diaphragm is to heat and stretch the diaphragm after being pre-cooled by the upper and lower rows of cooling and blowing devices, and then drive it to the mobile cooling table. For further cooling and shaping, the mobile cooling table can move as a whole according to the different arcs of the diaphragm to adapt to the arc transmission of the diaphragm after forming. There is also a diaphragm transmission correction device on the mobile cooling table, which can correct the diaphragm Movement during transmission. [0003] Servo drive (servo drive) refers to the engine that controls the operation of mechanical components in the servo system, and is an auxiliary motor indire...
