Transmission for food extruders

The transmission device of the novel food extruder includes a transmission shaft provided with a bearing box and a screw shaft located in the extrusion cylinder, one end of the transmission shaft is fixedly connected with the output end of the reduction gear, and the other end extends out of the bearing box and the screw shaft The fixed connection is characterized by: the part connecting the drive shaft and the screw shaft is in the slag box. Therefore, the dust generated in the production will fall into the bottom of the slag box, and will not be squeezed into the bearing box from the oil seal gap of the drive shaft connecting the bearing. Therefore, it can ensure that the lubricating oil in the bearing box always maintains a good lubricating performance within the specified period of use, thereby ensuring the normal operation of the equipment and reducing the production cost of the enterprise.
