Definitions

  • the present invention refers to a device for crushing plastic materials, cardboard, wood, foamed plastic, plastic bottles and the like.
  • the invention refers to a crushing device, making use of a rotor provided with cutting bodies co-operating with a fixed counter-cutting element, for polypropylene or cardboard or wood boxes, or other light recyclable materials as for example PET bottles or foamed plastic food trays.
  • Crushing devices are normally used for triturating waste in general, waste materials from wood manufacture or glass, ceramics or the like.
  • Known crushers can be classified in some main categories, according to the material to be crushed and the working principle.
  • a crusher for wood or cardboard normally comprises a rotating drum, having on its surface a plurality of cutting or crumbling protrusions, driven at high speed by a high power motor. The material to be crushed is pressed towards the rotating drum surface and consequently crushed in small fragments.
  • a second type of crusher commonly known as mill, has an hollow cylinder in which rotates at high speed a rotor comprising a rotating shaft and some hammers, normally hinged to the shaft itself and therefore partially movable.
  • the moving hammers and the co-operation with the internal surface of the cylinder causes crushing of the materials placed inside.
  • the crushing hammers can be provided with blades for facilitating cutting of not too hard materials, as plastics, light wood or cardboard.
  • Crushers and mills present on the market are always very huge, as they are designed for the treatment of large amount of materials.
  • a first object of the present invention is therefore to solve the problem of how to realise a crushing device for light materials, small, economically convenient and with easy maintenance.
  • the crushing device according to the present invention can be advantageously used for crushing plastic, wood or cardboard boxes, bottles or food containers in general, making the recycling process more efficient and cheap.
  • a cutting block 1 incorporated in a crushing device for crushing plastic materials, cardboard, wood, foamed plastic, plastic bottles and the like, comprises a rotor 11 having cutting bodies 3 co-operating with a fixed counter-cutting element 5.
  • the block 1 has a supporting structure which supports a rotating shaft 2 on which are inserted some hammers 3 placed side by side.
  • a first pulley 6 joins the shaft, by means of a rubber belt 7, with a main electric motor 61, while a second pulley 8, preferably incorporating a flywheel, is eventually used to drive other moving parts in the same machine, described later on.
  • the supporting structure of the crushing block 1, visible in figure 2, comprises fundamentally two lateral square walls 22 and 23 joined, in correspondence of vertices, by four transversal bars, two of which are visible in figure 2 with numeral references 24 and 25.
  • Each wall has in the middle a hole in which is inserted, by means of suitable bearings, the rotating shaft 2.
  • This compact structure of the crushing block 1 makes the block itself independent from the machine allowing an easy and rapid separation from the frame 10 in case of routine maintenance or for a quick replacement.
  • a plurality of hammers 3 having an elongated shape, radially offset one to each other to form an helicoid.
  • the central portion of the rotating shaft 2, which supports the hammers, has a square section.
  • the hammers have in their central portion a squared opening having dimension so that they can be inserted, side by side, on the rotating shaft.
  • the hammers which have all substantially the same shape, have each a squared central opening rotated of six degrees in respect to the opening of an adjacent hammer.
  • Each hammer visible in detail in figure 3, comprises two symmetric opposite portions, each having on its extremity a cutting surface 4 able to co-operate with a counter-cutting element 5.
  • the counter-cutting element 5 is a bar made of hardened metal or stainless steel, with a counter-cutting surface having a shape complementary to the shape of hammer's extremities.
  • the counter-cutting element 5 has some protrusions and some recesses corresponding respectively to the shorter and to the longer hammers.
  • the hammers could have all the same length and, consequently, the counter-cutting element could have a linear counter-cutting surface.
  • the cutting surfaces of hammers 3 are realised by means of hardened metal cutting bodies 4 fastened with screws 41 in recesses 12 obtained on the extremities of the hammers themself.
  • the cutting bodies 4 are squared and are sharpened on four sides in such a way that they can be rotated, inside recesses 12, by 90 or 180 degrees. This expedient extends their life, as they can be rotated at least four times, and makes easier the periodic maintenance of the device.
  • Figure 3 shows in particular four hammers, two longer and two shorter, inserted alternately on the rotating shaft 2.
  • figure 4 is shown the co-operation of a hammer 3 with a counter-cutting element 5 in a cutting phase.
  • the hammer's cutting surface meets the counter-cutting surface with an angle ⁇ of a few degrees.
  • the total number of hammers and the angular difference between adjacent hammers are calculated so that, during rotation of the shaft, only one cutting body is in a cutting phase in a particular moment.
  • Figure 5 is a whole lateral view of the crushing device.
  • the crushing block 1 is inserted in an apposite space in a metallic supporting frame 10.
  • the crushing block 1 receives from the top the material to be crushed by means of a slide 56 having a forced dragging system.
  • a second electric motor drives at reduced speed one or more driving belts 57 tight between two pulleys 58 and 59 and a series of toothed disks 60 that drag and push materials in the co-operating zone between hammers 3 and counter-cutting element 5.
  • rotor 11 furthermore is preferably provided a shield 13 made of punched plate that joins together with slide 56 in order to avoid relevant parts of material, eventually dragged by rotor 11 beyond counter-cutting element 5, being conveyed with the crushed material.
  • Said shield 13 allows to said relevant parts of material to rise in the sense of rotation of rotor 11 and to be further on crashed by rotor 11 while passing against counter-cutting element 5.
  • Crushed material is collected under crushing block 1 in a funnel shaped container 52 whose output is connected to an output channel 53 coming from a pusher fan 51.
  • Pusher fan 51 is driven by the main electric motor 61 by means of a driving belt 9 joined with the second pulley 8 of the crushing block 1.
  • Air pushed by fan 51 in the output channel 53 causes an eddy inside container 52, crushed material is efficacy and rapidly removed from the crushing machine and can be sent to a collecting container.
  • a ramification in the channel that permits to send to different containers different materials as plastics, cardboard or wood.
  • fan 51 is replaced by a drawer for collecting crushed material, placed directly under shield 13 or in the space where is placed the fan 51.
  • the output channel 53 will be closed by a removable lid so that crushed material can be collected in the drawer.
  • the metallic supporting frame 10 moreover can be easily covered by sound-proofing material, in order to silent the machine and allow the installation in a working ambient.
  • the crushing device described can be realised, substantially without structural modifications, in various dimensions.
