Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. The belt conveyor roller with the deviation preventing function is formed as shown in figures 1 to 5 and comprises two symmetrically arranged mounting seats 1, and a driving shaft 2 is rotatably arranged between the two mounting seats 1; a roller body 3 is arranged on the driving shaft 2, and a friction layer 4 is sleeved in the middle of the roller body 3; a plurality of annular and uniformly distributed mounting grooves 5 are formed in the positions, corresponding to the two sides of the friction layer 4, of the roller body 3, and a base 6 is arranged in each mounting groove 5; a plurality of uniformly distributed grooves 7 are formed in the top surface of the end part, far away from the friction layer 4, of each base 6, and an electromagnet 8 is installed in each groove 7; the top surface of the end part of the base 6 close to the friction layer 4 is provided with an anti-deviation piece 9 through a torsion spring, and the bottom surface of the anti-deviation piece 9 is provided with a plurality of absorbing pieces 10 matched with the electromagnets 8; a photoelectric sensor 11 is arranged on the top surface of the deviation preventing piece 9 close to the end part of the friction layer 4, and the photoelectric sensor 11 is electrically connected with the electromagnet 8; and a resetting device for resetting the deviation preventing piece 9 is arranged on the side surface of each mounting seat 1 close to the other mounting seat 1.

A clamping groove 12 positioned on the base 6 is arranged between every two adjacent grooves 7; a clamping block 13 is arranged between every two adjacent suction pieces 10, and the clamping block 13 is matched with the clamping groove 12; the resetting device comprises a mounting rod 14, and a resetting cylinder 15 is arranged on the side surface, facing the driving shaft 2, of the mounting rod 14; a reset rod 16 is arranged on the reset cylinder 15, and a push rod 17 is vertically arranged at the end part of the reset rod 16; the reset cylinder 15 drives the push rod 17 to move towards the deviation preventing piece 9, and the reset cylinder 15 is electrically connected with the photoelectric sensor 11; the friction layer 4 is provided with a plurality of evenly distributed friction portions 18 on the surface.

The working principle is as follows: during specific work, two roller bodies 3 are arranged at two end parts of the belt conveyor through the mounting seats 1, and then the flexible conveying belt is arranged between two friction layers 4; then the whole roller is connected with an external safe commercial power, the electromagnet 8 and the photoelectric sensor 11 are electrified and started after being electrified, and the electromagnet 8 is tightly attracted with the attraction piece 10 after being electrified, so that the deviation preventing piece 9 is in an initial state in a parallel state with the base 6; then, the driving shaft 2 is driven to rotate by an external driving motor, and the roller body 3 is driven to rotate after the driving shaft 2 rotates, so that the friction layer 4 can drive the flexible conveying belt to circularly move; when the flexible conveyer belt deviates, the flexible conveyer belt moves to the position above the deviation preventing part 9 at the deviation side, the flexible conveyer belt can shield the photoelectric sensor 11 on the deviation preventing part 9, the photoelectric sensor 11 can be shielded and then the electromagnet 8 is controlled to be powered off by an external controller (the controller can be an externally arranged control center, and can also be an FX2C-20MRD, Cortex-R8, Cortex-M7 or other types of programmable controllers), a magnetic field can not be generated when the electromagnet 8 is powered off, so that the connecting force between the electromagnet 8 and the attraction part 10 disappears, the acting force of the torsion spring on the deviation preventing part 9 is larger than the connecting force between the fixture block 13 and the clamp groove 12, the deviation preventing part 9 can turn over upwards under the action of the torsion spring, and the flexible conveyer belt can be automatically pushed to the friction layer 4 direction in the process of turning over of the deviation preventing part 9, thereby realizing automatic deviation rectifying work and leading the whole roller to have the deviation preventing function; in the process that the driving shaft 2 drives the roller body 3 to rotate, the roller body 3 can drive the deviation preventing piece 9 to rotate in the direction of the reciprocating position cylinder 15; after the anti-deviation part 9 that appears the upset moves to the cylinder 15 that resets one side, the controller will control the cylinder 15 that resets and the circular telegram of electro-magnet 8 and start, can drive release lever 16 and move toward anti-deviation part 9 direction after the cylinder 15 that resets starts, can drive push rod 17 after the release lever 16 moves together, the in-process that push rod 17 removed can be automatic promotes to prevent that inclined to one side part 9 from overturning toward base 6 direction, finally make the piece 10 that closes of inhaling each other with electro-magnet 8, thereby make the piece 9 that prevents partially get back to the state parallel with base 6 again, in order to make things convenient for follow-up to use later.
