Automatic error correcting system of short leather belt and its method

Abstract

This invention relates to a system and a method for calibrating short belt against a correct position. A system consists of a four-bar-linkage, a motor a cam, which is hinged with a push rod, and a position monitor. The four-bar-linkage is used as an actuator. The motor drives the cam to actuate the four-bar-linkage via the push rod hinged with the cam. The push rod is respectively hinged with the cam and a movable rod of the four-bar-linkage as its both ends. The position monitor is equipped with a detecting lever. A roller is elastically pressed to contact with an edge of the belt. The method is carried out by: feeding the detected position signals into computer system, outputting a calibrating signal to the motor and to change the tension forces on both edges of the conveying belt via the cam mechanism and actuator. It is simple and reliable.

Description

technical field [0001] The invention belongs to belt conveying loading and unloading equipment, mainly used for loading, unloading, conveying and feeding coal and other bulk materials. It is an invention and creation related to a belt deviation correcting device and a deviation correcting control method. Background technique [0002] In domestic coal handling equipment, the feeder system mostly adopts two forms: vibration feeding and belt feeding. The technical process of the vibrating feeder is to drive the reciprocating motion of the hopper through the cam mechanism and the spring shock absorbing mechanism to realize vibrating feeding. Most of them are random accessories of foreign complete sets of equipment. The advantages are low hardware cost, simple installation, and easy maintenance; the disadvantages are high noise, high energy consumption, and high mechanical wear. The most fatal shortcoming is: when encountering coal with fine powder, high humidity, and high visco...

Problems solved by technology

Most of them are random accessories of foreign complete sets of equipment. The advantages are low hardware cost, simple installation, and easy maintenance; the disadvantages are high noise, high energy consumption, and large mechanical wear.

The most fatal shortcoming is: when encountering coal with fine powder, high humidity and high viscosity, coal jams often occur, forcing the unloading process to be interrupted, which seriously affects work efficiency

However, as long as the equipment is in operation, manual monitoring is required. Due to the harsh working environment, it poses a great threat to the physical and mental health and personal safety of the staff.
