Pancake rolling machine

Abstract

This invention provides a dough rolling machine, comprising a housing assembly (left side plate, right side plate, side wall plate, and pre-feeding guide cover), a feeding device, a rolling clamping device, a dough pushing device, and two displacement positioners. The left and right side plates are provided with multiple shaft connection holes, grooves, receiving slots, and connection holes. The dough enters the rolling area via the feeding device, where the rolling clamping device clamps the dough to the rolling rod. Once rolling is complete, the dough pushing device pushes it out, and the displacement positioners assist in adjustment and positioning. Through this structure, automated dough rolling operation can be achieved, improving production efficiency and reducing manual labor.
