A laminated glass initial pressing production line

Abstract

The invention relates to the field of glass processing devices, particularly relates to a large-scale laminated glass production line, and more particularly relates to an initial pressing production line for initial pressing and vacuumizing automobile laminated glass such as front windshield glass of a coach. The production line includes a plurality of loading vehicles, conveying devices, air extractors, a sheet loading zone, a cold drawing zone, a constant temperature zone, a cooling zone and a sheet discharging zone, wherein the sheet loading zone, the cold drawing zone, the constant temperature zone, the cooling zone and the sheet discharging zone are disposed in order along the conveying direction of laminated glass. A constant temperature draught fan, a heater and a constant temperature air channel are disposed in the constant temperature zone. The outlet of the constant temperature air channel is lower than the bottom surfaces of the loading vehicles. The production line can ensure the temperature of each zone, can achieve cold drawing and hot drawing of the laminated glass well, can ensure that each sheet of laminated glass loaded does not leak, and can automatically avoid vacuum catastrophe in short time during sheet loading of the laminated glass, thus reducing false alarm and ensuring the production efficiency. The production line can also perform initial pressing and vacuumizing treatment and vacuum monitoring for glass such as front windshield glass of a coach.

Description

Technical field: [0001] The invention relates to the field of glass processing equipment, in particular to a large-scale laminated glass production line, in particular to a preliminary press production line for performing preliminary press and vacuuming on laminated glass on automobiles such as the front windshield of a bus. Background technique: [0002] The laminated glass on the car, especially the front windshield, is generally composed of two glass substrates and an intermediate diaphragm. Automotive laminated glass generally needs to go through the initial pressure production line for initial pressure treatment after the laminating process. The initial pressure treatment is mainly used to remove more than 70% of the air between the glass substrate and the intermediate diaphragm, and to make the glass substrate and the intermediate film The periphery of the diaphragm is sealed to prevent the entry of air and moisture during subsequent processing, and finally the glass s...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an initial pressure production line for laminated glass in view of the disadvantages of the initial pressure production line in the prior art that may easily cause vacuum leakage and false alarms when vacuum monitoring is performed on large-scale laminated glass.
