Intelligent adjuster and adjustment method for adjusting brush roll pressure in strip cleaning section

Abstract

The invention discloses an intelligent regulator and a regulation method for brush roller force-contact amount of a strip steel cleaning section. The intelligent regulator includes a cabinet. The front side of the cabinet is provided with a touch screen. A 24V switching power supply, a current receiving module, a digital input module, a CPU module, a digital output module, an analog output moduleand a memory module are arranged in the cabinet. The regulation method includes the following steps: 1) detecting and calculating non-load current and working current of a brush roller motor and brushroller force-contact amount current; 2) obtaining a stroke and a direction required by a force-contact regulation motor of the brush roller force-contact amount regulation device, converting values of the stroke and the direction into digital values, transmitting the digital values to the digital output module; and 3) controlling the force-contact regulation motor of the brush roller force-contact amount regulation device to run by the digital output module to realize downward or upward force-contact regulation of a brush roller. The advantages of the intelligent regulator and the regulationmethod are that the regulation of the brush roller force-contact amount is high in precision, accurate and simple in operation.

Description

technical field [0001] The invention relates to the technical field of adjusting the pressure of brush rollers in a strip steel cleaning section, in particular to an intelligent regulator and an adjustment method for regulating the pressure of brush rollers in a strip steel cleaning section. Background technique [0002] In the cleaning section of the cold-rolled strip, in order to prevent splashing of alkali solution, the brush rolls and support rolls are partly enclosed in the cleaning equipment, and the pressing force of the brush rolls cannot be observed; Strong, harsh environment, various detection components cannot maintain accuracy in this environment. Therefore, the calculation of the pressing amount of the brush roller in the cleaning section is usually completed by detecting the current of the brush roller. [0003] The reference value of the brush roller current that the adjustment method of the brush roller pressure in the traditional cleaning section relies on ...

Problems solved by technology

[0003] The reference value of the brush roller current that the adjustment method of the brush roller pressing amount in the traditional cleaning section is fixed or a few empirical values. Due to factors such as different degrees of wear and wear of the gear box of the brush roller motor, the current of each brush roller motor is different, and in the process of operation, the current of the brush roller may increase or decrease dynamically, relying solely on the brush roller motor It is difficult to ensure the accuracy of the pressing amount by adjusting the current experience value, so the cleaning quality of the strip cannot be guaranteed
