At this time, the rotating motor 71 is started, the rotating motor 71 drives the hard tube 322 to ascend and descend until the hard tube 322 moves to the height of the baking pan 52 needing to be charged, and then the electric telescopic rod 8 controls the hard tube 322 to move towards the baking pan 52, so that the discharge port of the hard tube 322 is located right above the baking pan 52 needing to be charged. Then the metering pump 33 is started, and the materials flow through the feeding kettle 31, the hose 321 and the hard pipe 322 in sequence and finally enter the baking pan 52. The whole feeding process is automatically carried out, so that the operation is convenient, and the working efficiency is improved.

When needs take off the slab frame 5 and the heating sheet layer 51 from the host computer box 2, slide the installation pole 11 to the second spout 122 in, make the opening part dislocation of hard tube 322 and host computer box 2 for the opening part of host computer box 2 can expose, for slab frame 5 and heating sheet layer 51 take out from the host computer box 2 and give way, be convenient for slab frame 5 and heating sheet layer 51 take out from the host computer box 2.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
