Description

An automatic variable speed belt conveyor

technical field

The utility model relates to the technical field of belt transmission devices, in particular to an automatic variable speed belt conveyor.

Background technique

A conveyor is a material handling machine that continuously conveys materials on a certain route, also known as a continuous conveyor. The conveyor can carry out horizontal, inclined and vertical conveying, and can also form a space conveying line, and the conveying line is generally fixed. The conveyor has a large conveying capacity, a long transportation distance, and can complete several process operations at the same time during the conveying process, so it is widely used. However, the traditional belt conveyor only has a single conveying function, and it keeps running during the intermittent process of material transmission, which consumes a lot of energy and wastes power resources.

Contents of the invention

The purpose of this utility model is to provide an automatic speed-variable belt conveyor, which can automatically adjust the speed and has no material suspension function, save power resources and reduce production costs.

In order to solve the problems existing in the background technology, the utility model adopts the following technical solutions: an automatic variable speed belt conveyor, including a pulley, an automatic control device, a counter, a variable frequency motor, and a drive roller, and the transmission front end of the pulley is set There is a counter, the counter is connected with the automatic control device, the automatic control device is connected with the frequency conversion motor, and the frequency conversion motor is connected with the driving roller through the belt.

The automatic control device includes a data collection unit, a counting comparison unit, a central controller, and a frequency conversion device, the collection unit is connected to the counting comparison unit, the counting comparison unit is connected to the central controller, and the central controller is connected to the frequency conversion device.

The utility model has the following beneficial effects: it can automatically adjust the speed and has no material suspension function, saves power resources and reduces production costs.
