Warning device for glass tape cracks

Abstract

The invention relates to a warning device for glass tape cracks. The warning device comprises a steel frame (1) fixed to an outlet of an annealing furnace; a pair of upper linear guide rail (3) and lower linear guide rail (4) with locking blocks (5) are connected with the steel frame (1); the upper linear guide rail (3) and the lower linear guide rail (4) are parallel to each other; the upper linear guide rail (3) comprises a first slide block (3a) and a first slide rail (3b); the lower linear guide rail (4) comprises a second slide block (4a) and a second slide rail (4b); the first slide rail(3b) and the second slide rail (4b) are both connected with the steel frame (1); the first slide block (3a) is connected with a set of photoemitter (6); the second slide block (4a) is connected witha set of photoelectric signal receiver (7); a glass tape (2) is located between the photoemitter (6) and the photoelectric signal receiver (7); the photoelectric signal receiver (7) is connected withan external controller. The warning device for the glass tape cracks has the advantages that the cracked glass tape can be detected in real time and treated in time and unnecessary yield loss and equipment failure can be avoided.

Description

technical field [0001] The invention relates to the technical field of float glass manufacture, in particular to a glass ribbon crack alarm device. Background technique [0002] The molten glass enters the tin bath, and glass ribbons of various specifications can be formed by adjusting the forming parameters. The glass ribbon enters the annealing kiln and gradually cools down. During the annealing process, fried plates may appear, often with transverse or longitudinal cracks. If the operator finds out that it is not timely, it is easy to cause damage to the cutting equipment. "Fried board" will cause output loss to normal production, and secondly, cause safety hazards to production line equipment. In severe cases, fried glass will damage the rollers of the annealing kiln. In addition, the glass sheet after frying is transported to the roller table at the cold end, which will cause inaccurate speed measurement, affect the accuracy of cutting size, and cause output loss again...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that glass cracks are prone to cracks in the existing float glass production but cannot be dealt with in time. A glass ribbon crack alarm device is provided, which can detect glass ribbon cracks in real time. Send out an alarm signal to avoid unnecessary output loss and equipment failure in production, and effectively protect the operating equipment of the annealing kiln and cold end of the production line
