Description

Technical Field

[0001] The utility model relates to the technical field of conveyor auxiliary equipment, in particular to an adjustable belt pressing mechanism for a belt conveyor. Background Art

[0002] Belt conveyor is a kind of conveyor with high conveying efficiency and wide application. It can be installed in different occasions, such as turning places, slopes or depressions, etc., and is very flexible to use. When belt conveyors are installed in different positions, some special mechanisms are needed to limit their conveying direction, such as deviation adjustment mechanisms, turning mechanisms, etc.

[0003] When the belt conveyor passes through a concave arc section, there is a risk of streamers, so it is necessary to install a streamer prevention device in the concave arc section. At present, when the belt conveyor passes through a concave arc section, a pair of trumpet-shaped bias-blocking belt rollers are generally installed on the middle frame of the conveyor to prevent and press the belt. Although this method can effectively prevent the conveyor belt from streamers, the bias-blocking belt roller needs to directly contact the side of the conveyor belt. When the tension is large, it will cause a large pressure on the side of the conveyor belt, causing the conveyor belt to be quickly damaged from the side, greatly shortening the service life of the conveyor belt; at the same time, sometimes when the pressure is too large, it will bulge the conveyor belt, causing the middle of the conveyor belt to bulge, causing the conveyed material to scatter. In addition, the existing bias-blocking belt rollers cannot be adjusted, and it is difficult to meet the needs of concave arc conveyors in many occasions.

[0004] In view of this, this application is hereby filed. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing biased belt roller for preventing the conveyor belt from floating in the concave arc section directly contacts the side of the conveyor belt, which will cause greater pressure on the side of the conveyor belt, thereby causing the conveyor belt to be quickly damaged from the side. The purpose is to provide an adjustable belt pressing mechanism for a belt conveyor. By adopting a belt pressing wheel to press on both sides of the front of the conveyor belt, the purpose of preventing floating can be well achieved. The outer circle of the belt pressing wheel is an arc-shaped structure and can rotate freely. It will be in rolling contact with the conveyor belt, which has a small impact on the conveyor belt and can effectively solve the problem of the original biased belt roller causing great damage to the conveyor belt. At the same time, the mechanism has good adjustability up and down, left and right, and can meet the use of concave arc conveyors in many occasions. It has the advantages of simple structure and good practicality.
