Technical Field
The utility model relates to the technical field of checkweigher rejection equipment, in particular to a dynamic checkweigher with a double rejection confirmation function.
Background
The remover is a device for removing unqualified products after the weight of the products is measured to be unqualified by the weight scale. The existing dynamic checkweigher is only provided with a rejection confirmation structure at the outlet end of the dynamic checkweigher, namely a photoelectric sensor is arranged on a conveyor at the tail end of the dynamic checkweigher, the trafficability of products flowing outwards from the conveyor is detected, and if the products are not sensed by the photoelectric sensor within a specified duration, the unqualified products are judged to be successfully rejected.
However, if continuous rejection occurs to cause failure of the ejector, or rejection speed is not matched with product conveying speed to cause that the product falls into the collecting box, or the product is blocked in a gap between the conveyor and the collecting box to cause equipment shutdown, the photoelectric sensor at the outlet end of the dynamic weight scale also fails to sense the product, but the product fails to fall into the collecting box successfully, and rejection fails.
