Description
Technical Field
The invention belongs to the field of extruder extrusion production in the rubber industry, and particularly relates to a dynamic calibration device and a calibration method suitable for an extrusion rice scale.
Background
The tread is used as the outermost layer of the tire and is a component with a large weight ratio, and the weight of the tread has a remarkable influence on the dynamic balance performance of the tire, so that the weight per meter (a meter scale device for measuring the length of 1 meter is installed on a linkage line, and the measured length is 1 meter) of the tread in the extrusion process of an extrusion line is always controlled as an important item. In order to ensure the accuracy of tread rice weight weighing, the weighing precision of the rice scale is indispensable to be checked.
The current method for checking the precision of the rice scale is static checking, namely, checking from 4 corners and the center by using standard weights. Because the rice scale device is installed on the linkage line, when gluing the part through the rice scale, glue the part and can exert gravity G to the rice scale. And the gravity G can be converted into a digital signal and displayed on an electronic screen, if the meter scale is higher than or equal to the linkage line, the tread gravity borne by the linkage line is transferred to the meter scale, so that the measurement length value is greater than 1 meter, the measurement weight value is greater than the actual weight value, and otherwise, the measurement weight value is less than the actual weight value.
The rice scale weighing value after static verification can not eliminate the difference of measurement results caused by the height difference of the rice scale and roller ways before and after the linkage line, so the static verification method has certain limitation and is difficult to calibrate the measurement precision of the rice scale in a working state. In the production process, the actual one-meter weight value of the rubber part cannot be weighed by a meter scale, so that whether the weight of the rubber part is qualified or not cannot be determined, the weight qualified rate of the rubber part is seriously influenced, and the return rate is improved. Meanwhile, rubber parts with unqualified weight flow into the next process for misuse, and serious quality problems are caused to finished tires.
