The present invention relates to the technical field of counting devices, and in particular to a counting device for ring
cutting of
plastic bottle caps, comprising a box, a counter and a
buzzer, wherein the counter is mounted at the bottom of the inner cavity of the box, the
buzzer is mounted on the front of the box, and the counter is electrically connected to the
buzzer, and the counting device for ring
cutting of
plastic bottle caps also comprises a support plate, a
discharge hole, a
discharge trough, a ring
cutting mechanism, a counting mechanism, a sleeve, a motor, a first rotating shaft, a turntable, a disc, a limit groove, a lifting mechanism and a baffle, wherein the support plate is fixedly connected to the upper surface of the box; the
discharge hole is opened on the right side of the upper surface of the support plate; the discharge trough is installed on the front of the box in a downward tilt from back to front, and the discharge trough is located directly below the discharge hole. It is suitable for cutting rings of
plastic bottle caps of different specifications, expanding the
processing categories, and having a ring cutting knife service life monitoring function, so that the ring cutting knife can be replaced in time to prevent the ring cutting knife from delaying replacement and reducing the ring cutting quality.
