Definitions

  • the present invention relates to a cereal milling device.
  • the invention relates to a mill which uses two milling rolls, a movable one and a fixed one.
  • the fixed roll is motorized by means of a driving pulley.
  • the footing that supports the rolls rests on a frame of the mill.
  • the footing supports the rolls by means of a fixed support, which is rigidly coupled to the footing and supports the fixed roll, and by means of a movable support, which is generally pivoted to the footing and supports the movable roll.
  • a second footing, a second fixed support and a second movable support are used in order to support the other end of the rolls.
  • the set constituted by two footings, two fixed supports, two movable supports and the means for adjusting the distance between the rolls forms a unit which can be inserted in, and extracted from, the frame of the mill without having to disassemble the various parts that form the unit.
  • This is an important characteristic, since it is possible to set up the unit before insertion in the mill, allowing to perform the main adjustments and checks in the workshop instead of directly on the milling plant. Moreover, all the roll replacement operations are speeded up, increasing the productivity of the plant.
  • the driving pulley is actuated by means of a set of belts which are driven by a motor drive unit which is generally arranged under the floor on which the mill rests. In this manner, the belts pass through an appropriately provided opening formed in the floor.
  • the aim of the present invention is to overcome the above drawbacks with a cereal milling device which includes: two milling rolls, of which one is movable and the other one is fixed; a footing for the rolls, which rests on a frame of the device; a fixed support, which is rigidly coupled to the footing in order to support the fixed roll; a movable support, which is supported by the footing in order to support the movable roll; a driving pulley for actuating the fixed roll; a second fixed support for the pulley; a coupling for connecting the pulley to the fixed roll, so as to allow the simultaneous extraction of the footing, the supports and the rolls from the frame.
  • the device according to the invention has two milling rolls 10 and 11: the roll 10 is movable and the roll 11 is fixed.
  • the footing 12 supports the rolls 10 and 11 and rests on the frame 13 of the device.
  • the fixed support 14 is rigidly coupled to the footing 12 and supports the fixed roll 11.
  • the movable support 15 is supported by the footing 12 by means of a hinge and supports the movable roll 10.
  • the structure is symmetrical on the two sides of the rolls, so that a footing 12, a fixed support 14 and a movable support 15 are present on each side.
  • the driving pulley 25 actuates the fixed roll 11 and is in turn actuated by the motor drive unit 26 by means of the belt 27.
  • the belt 27 passes through an opening which is formed in the floor slab 28 on which the device is rested.
  • the second fixed support 29 supports the pulley 25, supporting the shaft of the pulley 25 with bearings.
  • the second fixed support 29 supports a shaft 32 of the pulley 25 and allows an axial sliding of the shaft 32.
  • the coupling 30 connects and disconnects the pulley 25 with respect to the shaft 31 of the fixed roll 11.
  • the coupling 30 can slide inside the pulley 25.
  • the shaft 32 of the pulley 25 is rigidly coupled to the movable part 33 of the coupling 30 and can slide inside the pulley 25 in order to be remotely actuated.
  • the position of the movable part 33 of the coupling 30 can be remotely actuated, preferably by way of a pneumatic means constituted by the piston 34, which moves coaxially to the axis of the pulley 25.
  • the coupling 30 includes a plurality of teeth 35 which are arranged on the movable part 33 and engage a complementary plurality of teeth 36 which are arranged on the fixed part 37, which is provided on a shaft 31 of the fixed roll 11.
  • Each plurality of teeth 35, 36 lies on a plane which is perpendicular to a rotation axis of the fixed roll 11. With particular reference to Figure 4, the plane is shown by the dashed line 38.
  • the invention allows to achieve the aim and all of the intended objects.
  • it is possible to achieve simultaneous extraction of the footing 12, of the supports 14 and 15 and of the rolls 10 and 11 from the frame 13 with a particularly simple operation.
  • It is in fact not necessary to release the belt 27 by acting on the motor drive unit 26, as customary according to the prior art. Rather, by simply actuating the piston 34 it is possible to contrast the spring 39 and release the coupling 30.
  • the pulley 25 remains in the same position and with the same tension of the belt 27. This simplifies and greatly speeds up the operations for replacing the unit.
  • the invention is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept.
  • the type of coupling can be different, using various available systems, such as for example knurled couplings or others.
  • the second fixed support 29 can be connected to the frame 13 or can be fixed in other equivalent manners in order to achieve the intended aim and objects of the invention.
