Referring to fig. 9, substantially the same as the first embodiment, further, the spreading mechanism includes a rotating plate 603, and the rotating plate 603 is rotatably connected to the collecting frame 6.

When the high-quality products in the collecting frame 6 are observed to be excessively stacked, the rotating plate 603 is manually controlled to rotate to flatten the high-quality products.

The working principle is as follows: when the dynamic balance detection device is used, an annular detection piece to be detected is placed in the material discharging barrel 203, the detection piece at the bottom can be intermittently separated from the material discharging barrel 203 due to the up-and-down movement of the workbench 3, the driving shaft 2011 synchronously rotates when the motor 201 works, the workbench 3 is limited by the supporting column 1012, the first convex ball 3012 on the sleeve 3011 slides in the first U-shaped groove 2012, the first U-shaped groove 2012 is in a shape of a sine curve which is connected end to end around the driving shaft 2011, so that the rotating driving shaft 2011 drives the sleeve 3011 to move up and down, the workbench 3 fixedly connected with the sleeve 3011 synchronously moves up and down, when the workbench 3 moves up, the lifting rod 2025 can be extruded, the first wedge 2023 moves up, at the moment, the second wedge 2024 is pushed by the first wedge 2023 to slide outward, so that the second wedge 2024 sliding outward is extruded with the inner wall of the annular detection piece, at this time, the rotating driving shaft 2011 can drive the detecting piece to rotate, the detecting piece is not supported by the workbench 3 after the workbench 3 moves downwards, so that the detecting piece is separated from the mounting cylinder 202, the detecting piece continues to rotate under inertia at this time, so that the rotation of an unqualified product can generate axial runout, a good product can be thrown out for a long distance under inertia, the good product falls after being blocked by the first screening cylinder 304, the axial runout of the good product is small, the good product falls from the second screening cylinder 303, the workbench 3 sliding up and down enables the second convex ball 1017 to slide relatively in the second U-shaped groove 1016 on the rotating rod 1013, the second U-shaped groove 1016 is the same as the first U-shaped groove 2012, so that the rotating rod 1013 swings back and forth, when the workbench 3 slides downwards, the 1015 push plate fixedly connected to the rotating rod 1013 swings and pushes the push block 4 to slide, so that the detecting piece separated from the placing cylinder 203 is pushed to the placing block 302 by the push block 4, the new detection product pushed out by the excellent product placing block 302 which is not thrown out is extruded and pushed away to fall through the second screening drum 303;

the good products have large axial runout, and after the good products are separated from the mounting cylinder 202, the good products are thrown out for a long distance due to the large axial runout, so that the good products cannot fall off from the second screening cylinder 303, the blocking cylinder 1011 can prevent the good products from falling on the bottom plate 101, and simultaneously can prevent the good products from falling into the collecting frame 6, the good products directly fall on the bottom plate 101, and the bottom plate 101 is provided with an inclination, so that the good products slide off along the inclination and can be received at the sliding position;

when the workbench 3 moves up and down, the rotating rod 1013 rotates back and forth, so that the threaded rod 1014 on the rotating rod 1013 synchronously rotates back and forth, and since the supporting foot 1 limits the collecting frame 6, the collecting frame 6 cannot rotate, so that the threaded barrel 602 screwed on the threaded rod 1014 moves up and down, the threaded barrel 602 sliding up and down drives the mounting rod 6021 to synchronously move, so that the second telescopic rod 601 is lifted up by the mounting rod 6021, at the moment, the collecting frame 6 fixedly connected on the second telescopic rod 601 also moves up, so that the falling height of the collecting frame 6 and the superior product is reduced, the superior product is prevented from being broken, and meanwhile, the lifted collecting frame 6 can buffer the falling impact force of the superior product by matching with the damping action of the third spring 6012, thereby playing a role in protection;

when the push block 4 is not extruded by the push plate 1015, the push block 4 slides back under the action of the second spring 4011 to make the push block 4 perform reciprocating sliding movement, so that the first rack 402 moves synchronously, at the moment, the gear 403 is driven by the first rack 402 to rotate, so that the rotating gear 403 drives the second rack 5 to slide, the spreading plate 501 on the second rack 5 moves synchronously, the superior products collected in the collection frame 6 are spread, and the situation that the collected superior products are stacked too high and slide down or the falling of the detected superior products is influenced is prevented;

the flattening plate 501 slides to and extrudees the horizontal rod 703 when being about to reach the stroke end, horizontal rod 703 promotes the sway of down tube 704 this moment, thereby wobbling down tube 704 promotes montant 705 to rise, montant 705 promotes shutter 7 and rotates this moment, pivoted shutter 7 promotes push rod 701 and outwards stretches out, thereby the good product that the push rod 701 that stretches out will block at support column 1012 and bull stick 1013 goes out is released, prevent that the good product from piling up on bottom plate 101, shutter 7 and backplate 1001 can prevent that the good product from popping out, wobbling shutter 7 will probably drop on bottom plate 101 on the good product rebound bottom plate 101 outside.
