Steel belt deviation correction system of cooling forming machine for remote transportation of high-temperature material

Abstract

The invention discloses a steel belt deviation correction system of a cooling forming machine for remote transportation of a high-temperature material. A driving wheel and a driven wheel are connected through a steel belt, wherein one end of the driving wheel is fixed, and the other end of the driving wheel is fixed through a hydraulic cylinder; the two ends of the driven wheel are fixed respectively through a cylinder; the pre-tension of the steel belt between the driving and driven wheels is adjusted by two cylinders; the bottom of the steel belt is provided with a driving wheel carrier roller and a driven wheel carrier roller to support the bottom of the steel belt respectively; a compression roller is arranged at the upper side of the bottom of the steel belt between the driving wheel carrier roller and the driven wheel carrier roller; limit switches are arranged close to the bottoms at the two sides of the driven wheel steel belt respectively, limit switches are arranged close to the tops at the two sides of the driving wheel respectively, and each limit switch is connected with an alarm; the driven wheel is provided with a photoelectric sensor close to the bottom of each cylinder, a photoelectric sensor is arranged at a position, which is close to the top of the hydraulic cylinder, on the driving wheel, and the photoelectric sensors detect the deviation quantity of the steel belt respectively; and all the sensors and limit switch alarms are connected with an upper computer through a PLC (programmable logic controller). According to the invention, double-closed-loop control on the position of the steel belt at the driving wheel end and driven wheel end is realized, and real-time deviation correction of the steel belt transmission system is finished.

Description

technical field [0001] The invention relates to a steel belt drive deviation correction system, in particular to a steel belt deviation correction system for a long-distance conveying high-temperature material cooling forming machine. Background technique [0002] The steel belt high-temperature material conveying system is widely used in the chemical industry, plastic industry, oil refining, natural gas industry, cooling and solidification granulation, sliver making, flaking, biscuit baking in the food industry, etc. Usually, when the steel belt transports high-temperature materials, the bottom of the steel belt is cooled by spraying water, the forming machine has a large span, the operating environment is harsh, and there are abnormal conditions such as unstable feeding and uneven cloth distribution during work, resulting in uneven heating of the steel belt and the presence of steel belts. A certain degree of irregular deformation, steel belt deviation often occurs during ...

AI Technical Summary

Problems solved by technology

When the local deformation is too large, it takes a lot of force to change the axis position of the driving wheel or the driven wheel, and the stress of the belt may exceed the allowable value, resulting in a greatly shortened working life of the steel belt

[0006] (3) When the span of steel belt transmission is large, the existing deviation correction system has serious hysteresis, and lacks the functions of on-site monitoring, centralized control and parameter setting, resulting in untimely detection of deviation and difficult management

[0007] Therefore, for the steel belt transmission system for long-distance transport of high-temperature materials, there is still a lack of a device and control method that can quickly respond to the deviation and correction of the transmission system. It is urgent to design a real-time dynamic correction system based on PLC intelligent control.
