Electronic belt scale nutation type belt tensioning device

Abstract

The invention relates to an electronic belt scale nutation type belt tensioning device which comprises a tensioning framework, main body lateral plates and a link mechanism, wherein the tensioning framework is spanned over both ends of a driven roller of an electronic belt scale and is positioned between an upper belt and a lower belt, the main body lateral plates are symmetrically arranged at the two outer sides of the tensioning framework, the link mechanism is installed on the main body lateral plates, the link mechanism is formed by sequentially connecting pedestals, first connecting rods, second connecting rods and nutation plates, the pedestals are fixed on the main body lateral plates, the first connecting rods are articulated with the pedestals through first rotating shafts, the second connecting rods are articulated with the first connecting rods through second rotating shafts, and the nutation plates are respectively articulated with the second connecting rods through third rotating shafts and articulated with the main body lateral plates through fourth rotating shafts; fastening bolts are arranged on the nutation plates; wrenches are installed on the second connecting rods; and the nutation plates are also connected with the tensioning framework through first bearings, and the tensioning framework is connected with a central shaft of the driven roller through a second bearing. The electronic belt scale nutation type belt tensioning device has light structure and can rapidly realize the tensioning or relaxation of belts with labor saving, and the size of tensioning force can be accurately regulated in real time.

Description

technical field [0001] The invention relates to the structural technical field of a belt tensioning device of an electronic belt scale. Background technique [0002] Various electronic belt scales currently on the market use fixed tensioning, heavy hammer tensioning, or lever tensioning for belt tensioning methods, but no matter which tensioning method is used, it is very difficult. It is difficult to quickly tension or relax the belt, and the way of tensioning or relaxing the belt is complicated and difficult to operate; in order to make the tensioning mechanism produce enough tension on the belt, the tensioning device is often designed to be cumbersome, which is very difficult for the equipment. The assembly and commissioning work caused difficulties, and the equipment was too bulky, which was not conducive to transportation and placement.

Problems solved by technology

[0002] Various electronic belt scales currently on the market use fixed tensioning, heavy hammer tensioning, or lever tensioning for belt tensioning methods, but no matter which tensioning method is used, it is very difficult. It is difficult to quickly tension or relax the belt, and the way of tensioning or relaxing the belt is complicated and difficult to operate; in order to make the tensioning mechanism produce enough tension on the belt, the tensioning device is often designed to be cumbersome, which is very difficult for the equipment. Difficulties in assembly and commissioning work, and heavy equipment is not conducive to transportation and placement

[0003] On the other hand, when the belt needs to be replaced due to aging, damage or other reasons, due to the complex way of tensioning and relaxing the belt and the cumbersome mechanism, it often takes a long time and many people cooperate with each other to realize the replacement of the belt.

When the belt is replaced or the electronic belt scale needs to be adjusted, it is often required to adjust the constant tension of the belt. However, it is difficult to achieve real-time and accurate adjustment of the constant tension of the belt with various tensioning methods currently used.

As a result, the adjustment, maintenance and repair of the electronic belt scale conveyor are difficult and the workload is heavy

[0004] In addition, when the belt has a bell mouth or the adjustment of the rollers of the conveyor is not in place, the tension of the belt cross section will be unequal, resulting in belt deviation, excessive eccentric load, and poor measurement stability, which will affect the electronic belt. Normal use of the scale
