The stirring device includes a plurality of stirring subassembly, every stirring subassembly is located between two adjacent cantilever roller subassemblies, the stirring subassembly is including stretching into the pivot in the furnace body, pivot inner is equipped with a sloping block, it makes the blank break away from the cantilever roller and rolls to the guide rail along the inclined plane of sloping block downwards to drive the sloping block when the pivot is rotatory, a connecting rod is all equipped with to all stirring devices's pivot outer end, all connecting rod bottoms connect jointly on a synchronous connecting rod, driving motor is equipped with to one of them stirring subassembly's pivot outer end.

The bottom of the furnace body is provided with a plurality of discharge flue.

The working principle of the utility model is as follows: the blank is sent into furnace body inner by the cantilever roller of feed end after getting into from the feed inlet, then the action of stirring device, driving motor drives the pivot rotation and drives the pivot synchronous rotation certain angle of other stirring subassemblies through synchronous connecting rod, the sloping block of pivot inner moves when the top with the blank jacking and breaks away from the cantilever roller and roll down to the guide rail along the inclined plane, then driving motor drives pivot reverse rotation and makes the sloping block position descend and be less than the cantilever roller and prepare for next batch of blank material loading, the slow rotation of spiral drive shaft is with the blank to the propelling movement of discharge end, the blank is constantly heated in the propelling movement process, carry out the stove by the cantilever roller of discharge end outwards when pushing away to the discharge end at last.

Compared with the prior art, the utility model has the following advantage:

1. the spiral driving shaft is in left-handed and right-handed paired configuration, so that blanks in the furnace can be uniformly distributed when the blanks are driven to advance; 2. all the driving bearing supporting parts can be far away from a furnace body heat source, so that the bearings can dissipate heat and cool, and the working environment of the bearings is optimized; 3. the turning is converted into lifting motion by adopting rotary motion, so that the blank is lifted and rolls along the inclined plane to complete the turning motion, and the turning device is simple and reliable and has adjustable motion rhythm.
