Problems solved by technology

Specifically: 1. Change the physical verification of the belt scale from the cumbersome manual method to automatic; 2. Solve the problem that the physical verification must be stopped before the physical verification affects normal production; 3. Solve the problem that the physical verification is too wasteful of power and The problem of too much cost; 4. Solve the problem of low calibration accuracy caused by factors such as off-line; 5. Make the physical calibration of the belt scale simple and convenient, and improve the accuracy and reliability of the belt scale measurement

Embodiment Construction

[0032] The object of the present invention is achieved in this way: the belt scale for automatic physical verification can obtain two weighing signals of equal size by setting the main weighing frame and the auxiliary measuring frame to detect the weight of the material transmitted by the belt synchronously. Each weighing signal can be independently output and measured independently, and can be measured by subtraction to form a composite signal; the belt scale instrument measures and displays the flow and cumulative amount of the material transported by the belt by measuring the signal of the main weighing frame; By setting the standard weight and automatic hanging weight device, a standard weight is applied to the secondary measuring frame for standard transfer; the belt scale instrument automatically monitors whether the measurement is inaccurate by measuring whether the weight on the secondary measuring frame meets the standard , and once the measurement is found to be inacc...

Abstract

The invention relates to a belt weigher for automatically examining a substance, wherein the belt weigher can automatically perform on-line examination on the substance under the condition of normal material transmission of a belt and normal gauge work of the belt weigher. The belt weigher comprises a main weighing frame, a main weighing frame weighing sensor, a sensor supporting frame, a supporting roller, a speed measuring sensor, an auxiliary weighing frame, an auxiliary weighing frame weighing sensor, a sensor supporting frame, a supporting roller, an electric push rod, standard round-bar weights, a standard round-bar weight laying frame, a standard round-bar weight bearing frame, a terminal box, an instrument and so on.

Description

Technical field: [0001] The invention relates to a belt scale capable of automatic physical verification. It is a new type of belt scale that can automatically monitor whether the measurement is accurate when the belt is producing and transporting materials normally. If it is inaccurate, it will automatically perform online physical verification to automatically ensure accurate measurement. Background technique: [0002] At present, the use of belt scales has become very common. However, since the belt scale is dynamically measured, in order to ensure accurate measurement, it is necessary to carry out physical verification of the belt scale and calibrate the belt scale. However, physical verification of belt scales is a very cumbersome work. Since there is no better method, the physical verification of the belt scale mainly adopts the following manual methods: one is to use several cars to load the materials first, and weigh them on the car scale to determine the total wei...
