AI Technical Summary
In the current glass production process, the thickness difference between the two sides of the glass plate is large, which leads to inconsistent stress relief during annealing, affecting the cutting quality and causing warping or cracking. In addition, the existing cooling device cannot adjust the water spray coverage width to meet the cooling requirements of different products.
A glass edge cooling device was designed. Through an adjustable water spray pipe and water inlet pipe system, the water spray coverage range can be adjusted according to the width of the glass edge. The device includes a mounting frame, a support frame, a water spray pipe, and a water inlet pipe. The angle and position can be flexibly adjusted by using a universal joint and a locking device to ensure the stability and adaptability of the water spray coverage.
This improved the consistency of internal stress during glass substrate annealing, enhanced product production efficiency and quality, and ensured uniform cooling requirements for glass edges of different widths.
