Embodiment 1

[0011] Embodiment 1: A belt scale without a speed measuring sensor, including a scale body 1, a weighing frame 2, a sensor 3, a secondary instrument 4, and a weighing idler 5. An eccentric block 6 is arranged inside the cavity of the weighing idler 5. The eccentric weight 6 and the weighing idler 5 are connected by bolts. The length of the eccentric block 6 is equal to the length of the weighing idler roller 5 . The weight of the material on the belt transmits the weight signal to the secondary instrument 4 through the weighing idler 5 and the weighing frame 2. At the same time, because the cavity of the weighing idler 5 is provided with an eccentric block 6, the idler 5 is eccentric. When rotating, the sensor 3 will receive a regular sine wave weighing signal, and the secondary instrument can calculate the speed of the belt by counting, and then obtain the material flow of the belt scale.

Embodiment 2

[0012] Embodiment 2: The connection between the weighing idler 5 and the eccentric block 6 of the present invention is a plug connection, so that the eccentric block 6 of different weight and shape can be conveniently replaced according to different belt scale specifications and material flow.

Embodiment 3

[0013] Embodiment 3: The connection between the weighing idler 5 and the eccentric block 6 of the present invention is welded connection,

Abstract

This invention disclosed a sensor strap balance which consists of a balance, a linker, a sensor, a display, a roller. There was an eccentric block in the inner of the roller; the eccentric block connects to the roller. The invention could decrease failure rate in strap balance. The measurement was precise, the cost was low and the structure was brief.

Description

technical field [0001] The invention relates to a dynamic weighing instrument, in particular to a weighing belt scale. Background technique [0002] At present, belt scales are generally equipped with load cells, speed sensors, and weighing display controllers. According to the signals from the load cells and speed sensors, the material flow on the belt can be obtained after calculation, but the sensors are precision and vulnerable devices. The use environment of belt scales is generally harsh, which can easily cause damage to the sensor, especially the speed sensor can cause weighing distortion due to human cheating and other factors, causing losses to the enterprise; when the belt scale is used for batching, the weighing distortion will also affect The quality of the product after ingredients. Contents of the invention [0003] The invention solves the technical problem that the measurement of the belt scale is distorted due to the inaccurate transmission signal of the ...
