Conveyor device of packing machine for small tobacco packets made of transparent paper

The invention provides a conveyor device of a packing machine for small tobacco packets made of transparent paper. The conveyor device comprises a conveyor belt and an equipment support. The conveyor belt is used for conveying the tobacco packets, the equipment support is used for mounting the conveyor belt, a cover plate is arranged above the conveyor belt and is divided into a first cover plate and a second cover plate in the front-back direction along a tobacco packet conveying direction, one end of the first cover plate is hinged to one end of the second cover plate, and the other end of the second cover plate is fixed; a detecting device for detecting whether the height of the first cover plate changes or not is arranged on the first cover plate and is electrically connected with a control system for driving the conveyor belt to move. When unqualified tobacco packets are conveyed on the conveyor belt, a lifting moment arm can be formed for the first cover plate, the first cover plate is lifted, the detecting device detects that the first cover plate is lifted, a signal is transmitted to the control system, the control system transmits an alarm signal and a command for stopping the conveyor belt from running, and accordingly a protection effect can be realized. The conveyor device has the advantages that the probability that the unqualified tobacco packets are fed into forming wheels can be greatly reduced, and accordingly an effective operation rate of equipment can be increased.
