Definitions

  • the technical field involved in this invention is that of manufacturing machinery for processing wood, and in particular that of machinery for shredding wood for obtaining chips or shreds for industrial reuse.
  • chipboard as this has been done for many years now initially arose as a way to make use of the remains of low quality wood which could not be used in conventional furniture, which had always been made of solid wood.
  • chipboard involves two very important advantages as compared with using solid wood.
  • the first consists in making use of the remains of low quality wood or woods, and the second its low price in respect of solid woods.
  • This invention covers a grinding machine with great production advantages as compared with prior items, balancing the consumption flow of raw material placed in the hopper and also preventing damage through snagging, apart from facilitating the removal of any possible unwanted material.
  • This invention also allows automatic stoppage when there is any snagging, preventing the drive motors from continuing to run until there is a manual stop.
  • the machine covered by this invention is also designed for removing the shredded products by means of a conveyor belt, as well as removing any unwanted metal particles by means of an electro-magnet.
  • This machine has a pair of rollers turning in opposite directions which act on a central part, so that the cutting capacity is duplicated in an essentially identical space as compared with any of the twin-roller antecedents.
  • the central part is able to move downwards when the roller motion, along with the product that the machine is attempting to grind, exerts a force greater than the cutting resistance programmed for the material to be ground.
  • the tare setting of said central part would mean that this would move downwards, against the action of a spring or a pneumatic or hydraulic device, and in its displacement it would act on a mechanical, optical or other form of detector which cuts off the current for driving the motors, and where applicable all the auxiliary mechanisms that might be necessary to guarantee the safety of the operator removing the unwanted item.
  • the body of the machine has opening windows at both sides, as inspection panels for cleaning and removing any unwanted products as described above. Opening either of these inspection covers will obviously require/and or give rise to cutting off the current needed, to make it impossible for the machine to run in these conditions.
  • the motors have reduction units to adjust the speed of the rollers to the optimum running specifications.
  • the motor power and/or the turning speed are expected to be specifically prepared for the form of usage, as well as the material to be shredded or the conditions of the raw material. If the raw material is, for example, very fine wood, very high roller turning speeds can be used, whilst if the material to be crushed is plastic the heat produced by friction would also have to be taken into account to prevent an excessively high rotation speed from adversely affecting the cutting conditions or the resulting shredded material.
  • FIG. 1 represents the base of the machine on which the other items are held and in particular the shredding box 2 and a table 3 for supporting the motors 4.
  • 5 indicates a reception hopper for the material to be shredded and 6 opening inspection covers in the shredding box 2 at the bottom of the sides.
  • the motors 4 are provided with a cover 7 (individual or joint) fitted with the required safety means so that this part of the machine cannot be operating while the inspection panels are open.
  • rollers 8 turn by means of the motors 4 through a reduction unit 9 fitted between these, the speed and power of the motors 4 as well as the reduction ratio of the reduction unit 9 being adjusted to suit the particular needs.
  • the shredding box On two of its sides the shredding box has two opposite parts 10 which have "U" shaped cutaways which house the shredding rollers 8 and in which these are fitted, by means of securing plates 12.
  • the shredding box has a second internal hopper 13, converging downwards, fitted so that the exterior sides do not allow any part through, which is assisted by the turning motion of the roller which in this zone is upward (in normal operation conditions).
  • the rollers 8 move in opposite directions, and act on a central part 14, thus providing two cutting zones, as opposed to the single zone found in known antecedents.
  • a support base provided with elastic retraction means for withdrawal when a force greater than the usual level is applied to these, which might happen when the roller or the rollers attempt to crush extremely thick metal parts.
  • This central part 14 also has lateral stops 15 which prevent the material to be shredded from extending beyond the cutting zone, which would cause a particular flow of uncrushed material to parts of the machine where this should not reach, possibly damaging sensitive parts of the machine in any case.
  • the central part is held in a preferably "H" shaped structure by a base 18 with the relevant housing 19, fitted with side supports 16 set on support legs 17, in such a way that these supports 16 do not prevent or hinder the shredded material from falling through.
  • rollers are held at their ends 20 and 21 in the corresponding cutaways 11 made in the side parts 10 of the box 2 and provided with a slotted profile 22 on which a further spiral slot 23 is made.
  • the roller is connected to the motor through a reduction gearbox 9 by means of two connection flanges 24 and 25.
  • the cutting tools 26 are located on the roller surface, in any suitable arrangement, according to the profile of the central part against which this acts. It is thus possible for each turn of the roller to make one or more cuts in the material to be shredded (each ring has one or more cutting tools) and as a particular embodiment it being designed for the arrangement to be spiral in one or more lines per ring. Securing can be by means of welding, screwing or any other suitable securing means.
  • the set of grinding rollers 8 prevents any particular unshredded materials from remaining there, the collection thus being fully effective.
