Automatic loading and unloading checking device of electronic belt weigher

Abstract

The invention provides an automatic loading and unloading checking device of an electronic belt weigher, and relates to the field of electronic belt weighers. The automatic loading and unloading checking device comprises a base and a weigher body weighing frame, two symmetric weigher body fixing frames are fixedly connected to the upper surface of the base in the longitudinal axis direction, and two symmetric weighing sensors are connected to the upper surface of each of the two weigher body fixing frames. According to the automatic loading and unloading checking device of the electronic beltweigher, traditional multi-user manual weight hanging is replaced, one-key calibration is achieved, the labor strength is thoroughly reduced, and the labor productivity level is greatly increased, potential safety hazards of manual operation in an on-site dynamic state are eliminated, the safety of dynamic checking of the belt weigher is guaranteed, and good conditions are created for intelligentmanagement of the belt weigher and achievement of unmanned maintenance.

Description

technical field [0001] The invention relates to the field of electronic belt scales, in particular to an automatic loading and unloading calibration device for electronic belt scales. Background technique [0002] Electronic belt scales have been widely used in various fields of industrial production such as mining, metallurgy, chemical industry, food processing, pharmaceutical manufacturing, transportation, etc., to realize online measurement and automatic control management of industrial production. [0003] In the actual application process of electronic belt scales, in order to achieve high measurement accuracy, it is required to be frequently checked and calibrated. Therefore, the belt scale verification cycle is short and the verification process is very complicated. The national standard stipulates the use of "(manual) registered code verification" or "physical correction". The traditional calibration methods "physical calibration" and "manual hanging (weight / chain c...

AI Technical Summary

Problems solved by technology

The traditional verification methods "physical calibration" and "manual hanging weight (weight / chain weight)" verification workload is very large, cost a lot of manpower and material resources, and each verification requires repeated operations 3 to 5 It takes 3 to 5 hours, and the labor intensity is huge. At the same time, during the on-site dynamic test, the high-speed operation of the belt conveyor and the artificial high-intensity fatigue labor have added a lot of safety hazards.

Therefore, the electronic belt scales in many industrial sites cannot be calibrated and corrected normally according to the regulations, which makes the measurement results of the electronic belt scales have large errors, low stability and reliability, and the expected results cannot be achieved.
