Abstract

The invention discloses a calendar on-line thickness-measuring device, which overcomes the disadvantages of wasting time and energy and poor accuracy in prior measuring methods by a dial test indicator and a micrometer in site. In the invention, optical measurement-control principle is applied to extract parallel light of second derivative action circuit on the imaging edge of CCD photosurface; narrow square signal output is converted to obtain the thickness of the calendered goods to be measured through computer processing; any on-line thickness measurement of calendered goods to be measured can be implemented. The device consists of a bearing, calendered goods to be measured, a guild roll, a sensor device, a guild way, a slide rod, a ball screw, an actuating motor and a variable-frequency motor. The device provided by the invention has the beneficial effects of stable performance, high measuring efficiency, reducing labor intensity and accurate measurement, moreover, the accuracy difference is below 5mum, thus realizing automation and integration of measurement systems.

Description

technical field [0001] The invention relates to a calender equipment, in particular to a measuring device for on-line thickness measurement in the production process of rolled products of the calender. Background technique [0002] Calender is a molding machine widely used in rubber and plastic industries, and is widely used in the production of plastic films, tapes, adhesive plasters, floor leather and other products. The accuracy and stability of the product thickness is an important index to measure the performance of the calender. Failure of this index will not only affect the product quality, but also cause a lot of waste of raw materials. Therefore, the online thickness measuring device has become an indispensable and important part in the production of calenders. [0003] Traditional methods used in industrial field mainly include manual measurement methods based on manual measurement tools such as dial indicators and micrometers, or gamma and beta ray thickness meas...
