Definitions

  • a press of this type is known from DE-PS 27 24 060. Presses based on this principle have been further developed in order to achieve a higher output. For this purpose, the press section had to be extended while the binder hardening time remained the same.
  • An extension of the press section means in the case of rotary presses, i.e. in the case of presses with a rotating drum, in which the compression takes place between the outer drum shell and an endless steel belt, which is partially wrapped around the drum and is under tension, the drum diameter increases.
  • the latest presses of this type have drums with a diameter of 5 m, a bale length of approx. 3 m and a drum weight of approx. 110 t.
  • a disadvantage of such large presses is that due to the required assembly and manufacturing tolerances on the press when starting up and when empty, damage to the endless steel belt, the outer drum jacket and the pressure rollers occurs because these machine parts touch without metal to be pressed.
  • the press should also be able to produce the thinnest particle or fiberboard webs from one millimeter with extremely low thickness tolerances, high specific strengths and good bending and impact strength.
  • the radial adjustability of the axis of the press drum relative to the axes of the deflection and pressure rollers ensures that the axis of the very heavy press drum is fixed at one point.
  • the gap (distance) thus set between the drum jacket and the pressure and deflection rollers is adhered to exactly, which prevents damage to the steel printing belt and the roller and drum surfaces, because assembly tolerances and play of the individual components of the press are effectively eliminated.
  • the large drum Due to the definitive radial setting of the large drum axis, the large drum can be positioned exactly, so that despite the assembly-related tolerances of the components (stands and bearings), which can be up to 1.5 mm, an exact thickness adjustment of the web to be produced is achieved.
  • the radial adjustment of the axis of the press drum relative to the axes of the deflection and pressure rollers takes place by means of additional bearings arranged on the axle ends, to which a hydraulic cylinder which is supported on the stand acts.
  • the embodiment described in claim 2 provides an adjusting device with a hydraulic cylinder and a lever arm, so that the adjustment of the axis takes place about a fixed point arranged on the stand. Such an adjustment device is less expensive to manufacture and operate.
  • the adjustment device according to claim 3 with two hydraulic cylinders arranged parallel to each other below the drum axis and symmetrically on each side of the center of the axis is particularly advantageous since the adjustment force is doubled.
  • the press shown in Fig. 1 consists of the stand 1, which receives the central press drum 2.
  • the pressure rollers 2, the pressure rollers 3, 4 and 5 are assigned.
  • the adjustment of the press drum 2 is carried out by hydraulic cylinders 10 and 11 which are articulated on the additional bearing 12 and on the brackets 13.
  • the additional bearing is moved down, so that the assembly tolerance between the bearing body of the main bearing 16 and the stator 1, i.e. the gap 25 and the game 23 between the rolling elements 19 and the outer ring 20 is canceled.
  • a press nip of this thickness must be adjustable between the pressure rollers 3, 4 and 5 and the press drum 2, the thickness of the steel band 6 of about 1.8 mm also having to be taken into account.
  • the press drum When starting up the system, the press drum is therefore raised by means of the hydraulic cylinders 10 and 11 in order to prevent the endless steel strip from rolling flat, as a result of which the assembly play 24 between the stand parts 25 and 26, which is approximately 1.5 mm, does not depend on the web thickness can impact.
  • the scattered fiber layer can be entered into the press by means of a conveyor belt 28 and a fiberboard 22 with a thickness of 1.5 mm can be pressed without causing damage to the machine when starting up.
  • the hydraulic cylinders 10 and 11 also prevent the drum, which weighs about 110 tons, from acting deleteriously on the steel belt arranged between the pressure rollers 3, 4 and 5 and the drum shell 2, and also on the pressure rollers themselves.
