Hopper scale calibration device based on digital sensor

Abstract

The invention relates to the technical field of a measurement detection device, in particular to a hopper scale calibration device based on a digital sensor, comprising a frame of which the lower end can be connected with a hopper scale tressel, wherein a bumper is arranged on the frame, a digital type weighing sensor is arranged below the bumper, the lower end of the digital type weighing sensor is connected with the upper end of a lifting jack by a connecting piece, and the lower end of the lifting jack can be connected with a hopper bracket. The invention mainly solves the defect of the hopper scale calibration device of the existing analog sensor, also has the advantages of simple structure and low manufacture and use cost, shortens the calibration time and period when being used, simplifies the calibration mode, saves large numbers of manpower and material resources and has wide use value and popularization prospect.

Description

technical field [0001] The invention relates to the technical field of measuring and detecting devices, in particular to a calibration device for a hopper scale based on a digital sensor. Background technique [0002] Hopper scales play a pivotal role in ingredient control and cost accounting in industrial production. Its daily verification and weighing accuracy will directly affect the stable operation of production and the quality of products. The calibration method of hopper scales has been using the traditional weight calibration method for a long time, and different weights often need to be mounted for each calibration. Small-tonnage hopper scales can still be manually mounted with weights, while for large-tonnage hopper scales, hanging To install weights, you need to use weight hoists (such as electric or electro-hydraulic push rods) to mount them.

The calibration method of hopper scales has been using the traditional weight calibration method for a long time, and different weights often need to be mounted for each calibration. Small-tonnage hopper scales can still be manually mounted with weights, while for large-tonnage hopper scales, hanging To install weights, you need to use weight hoists (such as electric or electro-hydraulic push rods) to mount them. This method has great shortcomings and deficiencies: the calibration method is cumbersome, cumbersome, occupies a large area, and requires a lot of manpower , material resources, long calibration time, has been unable to meet the requirements of modern production technology

[0006] 3. When the device is used, as many sensors as there are sensors in the hopper scale, there are several calibration sensors, resulting in high cost of the device, and the accuracy of different calibration sensors may be slightly different, which affects the overall weighing accuracy

[0008] 5. The calibration sensor used in the device is an analog load cell, which has a short transmission distance and weak anti-interference ability

[0009] 6. The oil pressure loading method and structure of the jack used in the use of the device will affect the stability of the measurement due to the pressure fluctuation of the oil pressure loading
