Embodiment Construction
[0016] As shown in Figure 1, the present invention is implemented as follows: a simple single-roller weighing frame for testing the belt scale is installed on the belt conveyor 1, and is separated from the belt weighing frame 2 to be tested by a distance of two to three rollers; Start the belt conveyor 1, and convey the material 3 normally. At the same time, the belt scale instrument 5 to be inspected and the inspection belt scale instrument 7 are synchronized to accumulate and obtain the cumulative amount G of the material 3 running the whole circle of the belt conveyor 1 1 , G 2 ; Adjust the cumulative amount of the test belt scale instrument 7 to be the same as the cumulative amount of the belt scale instrument 6 to be inspected, and this adjustment is also easy to do, because the two scales are affected by the same belt tension and deviation, so The actual error caused is also the same. Then press the formula K=G 1 ÷G 2 Calculate to obtain the adjustment coefficient K 1 And th...

The on-line belt balance checking process includes the following steps: installing one checking belt balance in the belt conveyer with checked belt balance; making the checked belt balance meter and the checking belt balance meter to obtain the same accumulation value; regulating the accumulation value of the checking belt balance meter to the accumulation value of the meter, calculating the regulation coefficient of the checked belt balance, storing the coefficient in the checking belt balance meter; setting standard weight on the checking belt balance; subtracting the accumulation value of the checked belt balance from that of the checking belt balance meter to obtain the difference as the accumulation amount of the standard weight in the checking belt balance meter; and finding out the regulation coefficient of the checking belt balance and inputting the coefficient into the checked belt balance. The present invention can check several on-line belt balances simultaneously with one checking device.
Description
Technical field [0001] The invention relates to a method and a device for online inspection of multiple electronic belt scales in the process of conveying and measuring industrial materials by a belt conveyor. Background technique [0002] Belt scales have been widely used in automatic weighing of industrial bulk materials. In order to maintain the weighing accuracy of the belt scale, the belt scale must be checked regularly, that is, the adjustment coefficient K in the belt scale instrument must be corrected. At present, there are two kinds of inspection methods at home and abroad: one is physical inspection, that is, the belt scale is inspected with the result of static weighing of the physical object. The advantage of the physical inspection method is the highest degree of confidence, but the physical inspection investment is relatively large, and there are many problems such as long inspection time, laborious, and multiple transfers of materials. In particular, most of the si...
