Description

  The present invention is a dough division for receiving kneaded dough (hereinafter simply referred to as dough) used in the bakery and confectionery field from a hopper and dividing it into an appropriate amount for bread making. Related to the machine.

  A normal dough dividing machine of this type is provided with a dough extrusion cylinder and a dough extrusion opening at one end of the dough extrusion cylinder, and is provided with a plurality of dough extruded from the extrusion opening. And a divided block having a pocket. A piston is provided in the cylinder, and the piston is moved forward and backward relative to the dough extrusion opening of the piston by the driving means, thereby sucking the dough from the hopper and sucking the sucked dough into the dough extrusion opening. On the other hand, the division block is arranged between a position for receiving the fabric in the pocket (fabric receiving position) and a position for extruding and discharging the received fabric (fabric extrusion discharging position). The dough is divided by sliding on the dough extrusion end face provided with the dough extrusion opening of the dough extrusion cylinder. When the divided block is set to the dough discharging position, the dough received in the pocket is pushed out by the pushing piston slidably accommodated in the pocket, and the scraping blade is moved along the pushing surface of the pocket and pushed out. The scraped dough is scraped off, and the scraped dough is transferred to the next step.

  As a mechanism for operating the scraping blade, the scraping blade is usually lifted above the dough extrusion port by the cam mechanism, and the scraping blade is dropped by its own weight, or the scraping blade is driven by the link mechanism. (For example, Patent Document 1).
