An automatic weighing instrument integrated detection device

Abstract

The invention discloses an automatic weighing instrument integrated detecting device. A feeding system provides powder or granular materials for a to-be-detected gravity type automatic loading weighing instrument; weighing is carried out; after weighing completion, materials fall into a container through a blanking pipe and the materials are conveyed to a detection station by a conveying line; a detection system weighs the weight of the materials in the container; the conveying line is started and the container is conveyed to a next station; a liquid injection system caries out liquid injection on a filling scale and the filling scale carries out liquid injection on the container again and the weight is weighed; after weighing completion, a second automatic conveying line transports the container to the detection system and then the liquid injection system returns; the detection system weighs the weight of the materials in the container in an upgoing manner; and after weighing completion, a first automatic conveying line conveys the container to a next station and then the detection system returns. Therefore, the automatic detection of the dynamic weighing performance of the automatic weighing instrument is realized.

Description

technical field [0001] The invention belongs to the field of measurement performance detection of gravity charging scales and filling scales, in particular to an integrated detection device for automatic scales. Background technique [0002] Gravity-type automatic loading scales and filling scales are typical automatic weighing instruments, which are widely used in industrial and agricultural automatic production of quantitative packaging. The entire weighing process is controlled by a computer and completed automatically. It has the characteristics of fast weighing speed, high weighing accuracy, labor saving, labor saving, simple operation and convenient maintenance. Gravity-type automatic loading scales and filling scales are included in the "Catalogue of Measuring Instruments Managed by Law of the People's Republic of China" (type approval part). The ability to carry out routine static and dynamic verification of feeding scales and filling scales, but due to the high tec...

Problems solved by technology

[0003] At present, when the technical organization conducts the dynamic material test in the type evaluation and testing of the gravity automatic loading scale and the filling scale, the gravity automatic loading scale or the filling scale weighs first; after the weighing is completed, the material is manually dumped into the container In the process of manual handling and inspection on the metering equipment, the handling, unpacking, and return of materials are all done manually, which is time-consuming and laborious, with low detection efficiency and potential safety hazards for personnel. There is an urgent need for a fully automatic gravity-type automatic loading Dynamic test device for weighing instruments and filling scales
