[0030] The supporting member in this embodiment is a conductive supporting member, such as a stainless steel tray, and the bottom of the tray has air holes. The material to be dried is pulp molded products such as egg boxes and egg trays; the conveying mechanism in this embodiment includes a rotating drive structure and a sprocket assembly, and the sprocket assembly includes a driving wheel and a driven wheel. The rotating drive structure drives the sprocket assembly to rotate, thereby driving the chain 10 to move forward, thereby driving the pulp molded products on the tray to move in the drying chamber, and the drying mechanism works, thereby realizing the drying operation of the material to be dried; because the tray is driven by the chain 10, when the tray is stuck and causes the tray to tip over, the tray tipping over will contact the wire rope 20, thereby connecting the alarm circuit and triggering the alarm, thereby detecting a working failure of the drying equipment.

[0031] In this embodiment, the supporting member is set as a conductive supporting member, and the alarm is electrically connected to one pole of the power supply, and the alarm is electrically connected to the wire rope 20. At least the following methods can be used to connect the alarm circuit when the pallet overturns and contacts the wire rope 20:

[0032] One implementation method is to electrically connect the chain 10 of this embodiment to the other pole of the power supply, and set the horizontal interval between the chain 10 and the wire rope 20 to be smaller than the width of the pallet, so that when the pallet overturns, one side of the pallet keeps in contact with the chain 10 and the other side of the pallet keeps in contact with the wire rope 20, thereby realizing the connection between one pole of the power supply, the alarm, the wire rope 20, the pallet, the chain 10, and the other pole of the power supply, thereby connecting the alarm circuit and triggering the alarm, thereby realizing fault detection; wherein, the electrical connection between the chain 10 and the other pole of the power supply can be achieved in the following ways: (1) by electrically connecting the sprocket to the power supply; (2) by arranging a conductive wheel between the two sprockets, the conductive wheel chain 10 slidingly contacts, and the conductive wheel is electrically connected to the power supply; (3) by arranging a conductive brush between the two sprockets, the conductive brush is electrically connected to the power supply, and the chain 10 keeps in contact with the conductive brush during movement.
