Embodiment 1
[0030] When the present invention is used for the positioning of the cake delivery during the processing of special-shaped straight polygonal base cake rolling (word),
[0031] Send cake ( Figure 4 ) The front end of the pushing tongue 2 is consistent with the profiled straight polygonal flat cake 25. Through the reciprocation of the pushing tongue 2, the special-shaped straight polygonal flat cakes 25 in the flat cake storage barrel 7 are pushed one by one from the barrel position to the midpoint of the center line between the two rolling extrusion turntables.
[0032] In the process of pushing by the pusher tongue 2, since the gap between the combined elastic cake pressing positioning device and the blank cake support is smaller than the thickness of the blank cake, a comprehensive effect occurs: firstly, the blank cake 25 overcomes the elastic force of the transition pressure head block 10, The base cake is aligned and closely attached to the front end of the push tongue ...
