Electronic Belt Scale Swing Type Belt Tensioner

Abstract

Electronic belt scale sway type belt tensioning device, including a tensioning frame straddling the two ends of the driven roller of the electronic belt scale and located between the upper and lower belts, body side panels symmetrically arranged on both sides of the tensioning frame, installed on the machine The link mechanism on the body side plate, the link mechanism is composed of a base, a first link, a second link, and a yaw plate connected in sequence, the base is fixed on the side plate of the fuselage, the first link passes through the first The rotating shaft is hinged with the base, the second connecting rod is hinged with the first connecting rod through the second rotating shaft, the yaw plate is respectively hinged with the second connecting rod through the third rotating shaft and the side plate of the fuselage through the fourth rotating shaft; A set bolt is arranged on the plate; a wrench is installed on the second connecting rod; the yaw plate is also connected with the tensioning frame through the first bearing, and the tensioning frame is connected with the center shaft of the driven roller through the second bearing. The invention has a light structure, can quickly and labor-savingly realize the tension or relaxation of the belt, and the tension force can be precisely adjusted 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
