Description

Technical Field

[0001] The invention relates to a reversing roller structure, in particular to a reversing roller structure for a belt conveyor. Background Art

[0002] Belt conveyors are widely used in mining, metallurgy, coal and other industries to transport loose materials or finished items. When the conveyor belt is changing direction, the objects being transported are easily thrown out of the conveyor belt by inertia, so it is necessary to reduce the conveying speed of the conveyor belt, resulting in low transmission efficiency and affecting production efficiency. Summary of the invention

[0003] The object of the present invention is to provide a belt conveyor reversing roller structure to solve the above technical problems.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

The roller is a solid roller and the central axis is welded to the central axis. The roller has symmetrical structures at both ends and a plurality of hinge grooves with equal angles are provided on the circumference of the outer wall. A connecting hole A is provided at the inner end of the hinge groove. Axial barrel grooves are provided on the end faces of both sides of the roller. The diameter of the barrel groove is smaller than the diameter of the hinge groove. Trapezoidal guide grooves are respectively passed through the barrel groove and the plurality of hinge grooves. A connecting ring groove is provided on the inner wall of the guide groove. The plurality of hinges are respectively installed in the hinge grooves, and the movable barrel and the adjusting screw sleeve are installed in the barrel groove.

[0006] Based on the above technical solution, the folding leaf includes a leaf plate, a connecting column A, a folding plate groove, a folding plate, and a connecting column B. The outer wall of the folding plate is an arc-shaped surface and has the same diameter as the outer wall of the roller. Connecting columns A are fixed at the front and rear ends of the folding plate. The leaf plate is hinged to the connecting hole A of the folding leaf groove through the connecting column A. A rectangular folding plate groove is opened at the bottom of the leaf plate. One end of the folding plate is hinged to the outer end of the folding plate groove, and a connecting column B is fixed to the other end.

[0007] On the basis of the above technical solution, the movable cylinder includes a ring sleeve, a trapezoidal block, a connecting seat, a connecting hole B, and an internal thread. The ring sleeve slides axially in the cylinder groove, and the outer wall of the ring sleeve is integrally formed with a plurality of trapezoidal blocks of equal angles. The trapezoidal blocks are slidably connected along the trapezoidal guide groove, and the length is half of the trapezoidal guide groove. A connecting seat is fixed to the inner end of the trapezoidal block, and a connecting hole B is opened on the connecting seat. The folding plate is hinged to the connecting hole B of the connecting seat through a connecting column B, and an internal thread is provided on the inner wall of the ring sleeve.

[0008] Based on the above technical solution, the adjusting screw sleeve includes a screw barrel, a baffle, a rotating plate, and a connecting ring. The outer wall of the screw barrel is provided with an external thread, which is threadedly connected to the internal thread of the ring sleeve. A circular baffle is vertically fixed to the outer end face of the screw barrel. The diameter of the baffle is the same as the diameter of the roller. Multiple rotating plates are fixed at equal angles on the outer wall of the baffle, and a connecting ring is integrally formed on the inner wall of the screw barrel.

[0009] Based on the above technical solution, the blade moves through the maximum distance of the screw barrel and the rotation range is 0°-30°.

[0010] Based on the above technical solution, the screw barrel is connected to the connecting ring groove through a connecting ring, and the screw barrel can rotate 360 ​​degrees axially relative to the roller.

[0011] Compared with the prior art, the present invention has the following advantages: the multiple hinges of the present invention can be folded synchronously by manually rotating the rotating plate, and the folding angle can be freely controlled within 0°-30°, which is convenient for adjusting the conveyor belt to gather to the middle or one side, avoiding objects from being thrown out of the conveyor belt due to inertia when turning, and facilitating the transmission of objects with special low friction or spherical objects. Compared with the existing conveyor belt, the transmission speed of the conveyor belt can be increased, making the work efficient and accelerating the production efficiency.
