Problems solved by technology

[0003] In the process of conveying materials by the belt, if it encounters bad weather such as rain, the material will become wet and heavy, which will increase the load on the driving wheel motor, or cause water to enter between the belt and the driving wheel, making the belt and the driving wheel The friction between the driving wheels becomes smaller, which may cause the belt to slip and cause certain damage to the belt
[0004] At present, it is possible to detect whether the belt is slipping by measuring the speed of the driving wheel and the driven wheel, but the existing technology does not propose a specific implementation scheme for accurately determining the rotation speed of the rollers so as to accurately detect the belt slippage

Embodiment 1

[0020] In related technologies, the detection principle of detecting whether the belt is slipping by measuring the speed of the driving wheel and the driven wheel is as follows: figure 1 Shown, wherein, 1 is a roller bracket, 2 is a roller (driving wheel or driven wheel), 3 is a belt, 4 is a signal source, 51 is a sensor, 52 is a signal output line of the sensor 51, and 6 is a controller. Depend on figure 1 It can be seen that the signal source 4 is installed on the side of the roller 2 (driving wheel or driven wheel), and as the roller 2 rotates, the signal source 4 will send a signal during the rotation process. When the signal source 4 is opposite to the sensor 51, the sensor 51 The signal sent by the signal source 4 can be detected. At this time, the sensor 51 sends a pulse signal to the controller 6 through the signal output line 52. The controller 6 can calculate the signal source 4 according to the time point of receiving the pulse signal. The required time, and then c...

Abstract

The invention discloses a system for determining the rotating speed of a roller, and a system and a method for detecting the slippage of a belt. The system for determining the rotating speed of the roller comprises an encoder and a controller, wherein the encoder is connected with the controller through a signal output line, is arranged on a rolling shaft of a belt roller, is rotated along with the rolling shaft, and outputs a pulse signal through the signal output line when rotating at a set number of turns each time; and the controller is used for determining the actual rotating speed of the belt roller according to the number of the pulse signals output by the encoder within a set time. According to the technical scheme, the system is used for accurately determining the rotating speed of the roller, so that the slippage of the belt can be accurately detected.

Description

technical field [0001] The invention relates to the technical field of belt transmission, in particular to a roller speed determination system, a belt slip detection system and a method. Background technique [0002] Asphalt mixing plant (referred to as asphalt plant) is one of the key equipment for asphalt pavement construction. The asphalt plant often conveys materials (such as cold material, aggregate, powder, etc.) by means of belt transmission. In the belt transmission mode, the roller (including the driving wheel and the driven wheel) rotates at a certain speed, and the friction between the roller and the belt drives the belt to move, so that the objects placed on the belt can be conveyed. [0003] In the process of conveying materials by the belt, if it encounters bad weather such as rain, the material will become wet and heavy, which will increase the load on the driving wheel motor, or cause water to enter between the belt and the driving wheel, making the belt and ...
