and the guide mechanism 40 is arranged between the waste rejecting mechanism and the second conveying mechanism 30 and is used for guiding the unqualified products to be conveyed to the second conveying mechanism 30.
When the detected unqualified products pass through the waste removing mechanism, the waste removing clapper 10 rotates, the unqualified products are conveyed downwards along the waste removing clapper 10, the products are guided by the guide mechanism 40 and then conveyed to the second conveying mechanism 30 below, and the second conveying mechanism 30 conveys the unqualified products to the outside. When the qualified products are detected to pass through the waste removing mechanism, the waste removing clapper 10 does not rotate, the qualified products pass through the waste removing mechanism to the first conveying mechanism 20, and the first conveying mechanism 20 conveys the qualified products to subsequent equipment. Because the waste rejecting mechanism and the second conveying mechanism 30 need to pass through the guide mechanism 40, the waste rejecting clapper 10 can rotate by a small angle and then is further guided by the guide mechanism 40, so that unqualified and thick printed matters after detection can be rejected without damaging the printed matters.
In this embodiment, the waste-rejecting clapper 10 is connected to a driving device and driven by the driving device to rotate, the waste-rejecting clapper 10 can rotate downward by a certain angle, particularly, the angle is smaller and generally smaller than the bending radius of the inspected product, and then the unqualified product is conveyed obliquely downward along the waste-rejecting clapper 10, and then the unqualified product is continuously guided by the guiding mechanism 40 below to be conveyed obliquely downward.
