Description

Technical Field

[0001] The invention relates to an auxiliary turning device for a conveyor, belonging to the technical field of belt conveyors. Background Art

[0002] The belt conveyor drives the transmission roller through the motor to make the belt circulate, thereby driving the material placed on the belt to move. The material runs with the belt and is transported from the feed end to the discharge end. The rollers located at both ends of the belt for changing the direction of the belt provide support for the belt to flip. A shaft is installed at both ends of the roller, where the shaft is connected to the bearing seat through a bearing, and the bearing seat is installed on the support carrier through bolts. The belt conveyor is provided with a tensioning device to adjust the tension of the belt to ensure good contact between the belt and the roller. At this time, there is a tendency for the two rollers to move toward each other. With the extension of the belt and the increase of the material conveyed on the belt, the force of the roller moving toward the middle area of ​​the belt gradually increases.

[0015] 4. Adjust the position of the second rolling bearing along the stud so that the ring on the second rolling bearing contacts different areas of the drum. Then use the second nut and the third nut to limit the relative position of the second rolling bearing and the stud. Adjust the position of the ring as needed so that the ring contacts different areas of the drum. Avoid a certain area of ​​the drum from being worn and thinned due to long-term contact with the ring, which is beneficial to extend the service life of the drum.

[0016] 5. Install a rectangular column at the lower end of the support ear, and insert a rectangular plate in the rectangular groove, adjust the length of the rectangular plate in the rectangular groove, and make the base contact with the supporting carrier, and then use bolts to install the connecting seat and the base on the corresponding supporting carrier respectively.
