Definitions
- the invention relates to a cube press for the production of feed cubes or the like (e.g. also wooden cubes) as well as a clamping device for changing the shapes and a roller adjustment in such a cube press.
- a cube press for the production of feed cubes or the like (e.g. also wooden cubes) as well as a clamping device for changing the shapes and a roller adjustment in such a cube press.
- Cube presses or feed cube presses or pellet presses have been in practical use in the feed and food industry or in the non-food sector for many years. Granular, powdery and / or pasty materials with different moisture contents and compositions are pressed.
- Such a cube press is e.g. in EP-A-371519.
- the material to be pressed passes from a hopper into a conveyor and metering device and from there into a mixer. Both devices are arranged on the top of the housing of the actual press, the outlet of the mixer conveying into a kinked filler box (and into a molded lid) which is arranged below but is not rigidly connected to the mixer. The material reaches the press mold from the mold cover.
- a mold is firmly connected to a rotating mold holder.
- a roller carrier with a roller web attached to it is also fixed.
- Two rollers are arranged so that they can be adjusted by means of a piston-cylinder unit, so that different gaps and pressures can be set on the molding die.
- EP-B-489046 Another pelletizing press is shown in EP-B-489046, in which the mold and at least one press roll can be driven at variable speeds and as a function of the gap height.
- Various solutions are known for fastening the molds in a cube press.
- the fixed arrangement mentioned at the outset which includes simple screwing of the mold, is cost-effective but requires a time-consuming mold change.
- Solutions for a quick change for example according to USP 4979887, are also known, in which, for example, the individual clamping segments are actuated by short-stroke hydraulic cylinders on the circumference of a shooting ring. To change the shape, the hydraulic cylinders are connected to an external hydraulic pump.
- DE-OS 2108326 it is also known, for better assembly, to hold the clamping segments in the position clamping the die by means of spring elements, with adjusting means being provided to release the clamping segments against the spring action. By overcoming the spring tension forces, the die should be able to be easily detached from the column or reattached. Hydraulic winches are used as actuators.
- DE-OS 2756647 A similar solution is shown in DE-OS 2756647, in which a conical ring is used to attach the die.
- the object of the invention is now to design a cube press in such a way that a simple and at the same time sanitation-appropriate and inexpensive change of shape is made possible.
- the object is achieved with the features of claim 1.
- the invention is based on the knowledge of actuating all clamping segments at the same time by means of only one element, so that the shape can be released from the cube press. This is preferably done by means of a pressure ring which can be moved in the axis of the mold by various force systems.
- power systems can e.g. consist of:
- Another object of the invention is to provide a roller adjustment of the press rollers for such a cube press that is simple in construction and maintenance. This object is achieved with the features of claim 11.
- 1 a cube press in partial section.
- 2 an embodiment of a tensioning device.
- 3 an embodiment of a roller adjustment.
- 4 the drive of a cube press.
- 5 an embodiment of the main shaft.
- a cube press 1 the material to be processed is fed via a hopper 2 to a metering device, which in turn forwards predetermined amounts of the material to a mixer 4.
- a mixer 4 water vapor and additives can be added.
- the material then remains in the dwelling 4 'for a certain time.
- the material mixed and prepared in this way then enters a channel 5, which feeds it to a mold cover 6, from where it enters the interior of a mold (die) 8 via scraper blades 7 and there with the help of press rollers 9 through radial bores 10 of this shape 8 is pressed through.
- the pellets are discharged via a channel 16.
- the mold 8 is held by means of a ring 12 fastened to a rotatable mold carrier 11 and a pressure ring 13. If necessary, the mold carrier 11 can be rotated manually by inserting levers into holes 14. In the normal case, however, the drive takes place via a drive wheel 15.
- the guides are formed from screws 18 and spring assemblies, which go through the pressure ring 13 and are screwed to the clamping segments 17. A pressure is exerted on the screws 18 by means of the pressure ring 13.
- a fluidic element Arranged behind the pressure ring 13 in the direction of the ring 12 is a fluidic element in the form of an air cushion 21 which, after filling, enables the pressure ring 13 to move axially.
- a repulsion mechanism is designed to be completely symmetrical, so that a simple construction results and unbalances are avoided.
- the sequence of movements can also take place in the opposite direction.
- the press rollers 9 are adjusted by a mechanical arrangement in the process space 30, which is accessible after the cover is removed and can also be operated manually.
- the arrangement of the press roller adjustment consists of one on the Main shaft 33 fastened base 31, on which two pairs of yoke-type lever arms 32 are arranged in the middle in an articulated manner.
- the opposite ends of the lever arms 32 are articulated to eccentrics 34 of the press rollers 9.
- the pairs of levers can be guided in a guided manner by means of a spindle 35 and the press rollers 9 can therefore be adjusted via the eccentrics 34.
- the adjustment mechanism is only slightly loaded and the possible large adjustment paths require fewer readjustments of the eccentric 34.
- a measuring system for a force limitation is provided.
- the drive for the roller adjustment is arranged outside the product space and acts on the adjustment mechanism through the main shaft 33.
- the pellet press is equipped with a lubrication arrangement that no longer requires a central lubrication system (electric grease pump), but that does not require the daily manual lubrication of today's manually lubricated pellet presses.
- a central lubrication system electric grease pump
- the press rollers 9 are equipped with standard, life-lubricated bearings. The relubrication of these bearings takes place at the earliest when the roller rings 36 are replaced due to wear.
- the bearings 37 of the roller holder shaft (main shaft 33) are also equipped with a grease reservoir 45, so that the grease flows very slowly through the bearings and enables large lubrication intervals, which corresponds to this approximately the life of the roller and cage assemblies 36 and can therefore be carried out in the course of the ordinary maintenance work.
- the grease can be distributed up to the roller adjustment. It arrives in the depot and, if necessary, in further locations by means of a tube arranged in the main shaft 33.
- the drive wheel 15 arranged on the main shaft 33 is driven via belt drives by two high-speed motors 40 arranged parallel to the main shaft 33.
- a vertical shaft 42 is first driven and by means of V-belts (Poly-V) 43 the overriding on the main shaft 33 takes place.
- V-belts 43 are preferably provided.
- the motors 40 can each be adjusted without slippage by means of rubber spring elements (49). These rubber spring elements have a damping effect and vibrationally separate the motors from the base frame of the pellet press.
- the belts (41) are pre-tensioned with these rubber spring elements and retain a constant pre-tensioning force without re-tensioning even when the belt length increases.
- a simple, two-stage gear is thus achieved with which different molding speeds can be set.
- An output speed of approx. 1500 U "1 can easily be reduced to approx. 200-250 U “ 1 of the form.
- speeds can be varied well and adapted to the respective product.
