Problems solved by technology

No load cell is designed to be installed on the curler, nor is a height sensor installed downstream of the curler to monitor whether the edge of the glass ribbon is rolled up or there are large inclusions on the glass surface. When the plate width is abnormal during the forming process, it is necessary to The operator discovers in time, and then the operator judges subjectively, and gives execution orders to each execution equipment (such as the main drive s speed, tin bath exit retaining wall, tin bath exit electric heating, tin bath narrow section electric heating, etc.), each execution The equipment then executes the command operation; therefore, each execution equipment is semi-automatic, and the execution of commands depends on human subjective judgment and human-made commands, lack of intelligence, and human subjective judgment will also have the disadvantage of inaccurate and untimely operation

Abstract

The embodiment of the present invention provides a detection and processing system for plate width accidents in the float glass forming process, which includes a tin bath electric heating device, an edge pulling machine, a main drive and a central control device electrically connected to the above-mentioned equipment. The detection and The processing system also includes a tin bath filled with tin liquid, and the tin bath has a wide section of the tin bath, a narrow section of the tin bath and a narrow section of the tin bath that are installed continuously in order from left to right; the main drive is arranged on the tin bath The right side of the narrow section of the tank is used to pull the glass ribbon placed on the tin liquid in the tin tank; the edge pulling machine is arranged on both sides of the wide section of the tin tank. The force sensor, the infrared height sensor, the infrared temperature sensor at the tin bath outlet, the electric heating of the narrow section of the tin bath, the electric heating of the tin bath exit area, the tin bath exit retaining wall and the main drive are integrated by PLC or DCS to realize the molding process The monitoring and prevention of abnormal board width changes make the float forming process more systematic and intelligent.

Description

technical field [0001] The invention relates to the field of float glass, in particular to a detection and processing system for plate width accidents in the float glass forming process and a detection and processing method for plate width accidents in the float glass forming process. Background technique [0002] With the improvement of the float glass equipment level, the continuous improvement of the float process, the technology is becoming more and more perfect. Flat glass with a thickness of 0.1mm to 25.0mm can be manufactured by the float process, but for the manufacture of ultra-thick (above 18.0mm) glass, and the manufacture of ultra-thin (below 1.0mm, especially below 0.5mm) glass, currently The requirements for equipment and technology are very high, especially the current use of electronic glass has increased significantly, and the demand for ultra-thin glass will increase significantly. If the float process can be used to manufacture electronic-grade ultra-thin ...
