When in work: the first motor 4 drives the roller 3 to rotate through belt transmission to drive the conveying belt 2 to slide, the material at the bottom is carried to a high position, the adjusting carrier rollers 8 on the two sides are matched with the horizontal carrier roller 6 in the middle to support the conveying belt 2, the supporting capacity of the conveying belt 2 is improved, the adjusting carrier rollers 8 on the two sides support and block the two sides of the conveying belt 2, the middle of the conveying belt 2 is sunken downwards, and therefore the probability that the material falls from the two sides of the conveying belt 2 is reduced; when the conveyer belt 2 deviates, the conveyer belt 2 deviates to one side, the second motor 9 on the same side rotates forwards to drive the driving bevel gear 10 to rotate and drive the driven bevel gear 11 meshed with the driving bevel gear to rotate, the driving support rod 7 rotates upwards to enable the other end of the support rod 7 to slide upwards along the arc groove 12 to drive the adjusting carrier roller 8 to rotate upwards, the second motor 9 on the other side rotates backwards to drive the adjusting carrier roller 8 to rotate downwards, so that the conveyer belt 2 moves towards the middle of the horizontal carrier roller 6 under the action of the height difference of the adjusting carrier rollers 8 on the two sides, the position of the conveyer belt 2 is adjusted, the difficulty of adjusting the conveyer belt 2 by a worker is reduced, the probability of damage of the conveyer is reduced, and the production efficiency is improved;
when the conveying belt 2 moves, the adjusting carrier roller 8 is driven to rotate along the supporting rod 7, the ejector rod 15 is driven to rotate, when the ejector rod 15 rotates to the top, the circular plate 16 contacts the elliptical convex plate 13, the circular plate 16 is attached to the elliptical convex plate 13 to slide, the circular plate 16 pushes the ejector rod 15 to slide to the inside of the sliding hole 14, and the top seat 19 is pushed to slide out of the accommodating groove 18, so that the balls 20 and the bottom surface of the conveying belt 2 are enabled to reduce the friction force between the conveying belt 2 and the adjusting carrier roller 8;
meanwhile, when the circular plate 16 pushes the ejector rod 15 to slide out of the slide hole 14, the elastic sleeve 21 is compressed, air in the elastic sleeve 21 is sprayed out from the air hole 22, air flow is gathered to the middle of the ring seat 23 through the blocking of the ring seat 23, the fan-shaped membrane 24 is blown to turn over outwards to expose the air hole 22, dust on the bottom surface of the conveying belt 2 is blown off, high-speed air flow is blown to the bottom surface of the conveying belt 2, the pressure of the conveying belt 2 on the balls 20 is reduced, meanwhile, dust on the surfaces of the balls 20 is blown off, and the rolling smoothness of the balls 20 is improved;
when adjustment bearing roller 8 rotated, when gas pocket 22 rotated the bottom, plectane 16 broke away from oval flange 13, spring 17 resets, promote plectane 16 to the inside removal of adjustment bearing roller 8, it is inside to drive ejector pin 15 and slide in adjustment bearing roller 8, make elastic sleeve 21 reset, when fan-shaped diaphragm 24 overturns to the inboard, blocked by annular frame 25, external gas gets into the inside of gas pocket 22 from hole 26, thereby the inside air current velocity of external gas entering gas pocket 22 has been reduced, the dust has been reduced and has been accompanied gaseous probability that gets into elastic sleeve 21 inside, fan-shaped diaphragm 24 contact annular frame 25, the magnet 28 inter attraction of both sides, the intensity of fan-shaped diaphragm 24 laminating annular frame 25 has been improved.
