Definitions
- the invention relates to a roller mill for grinding grain and the like to flour, semolina, haze, etc. It is particularly directed to the overdrive in such roller mills with at least one pair of rollers with corrugated or smooth rollers
- Roller mills for grinding grain usually contain two or four pairs of rollers, as is described, for example, in DE-C-2730166 or in EP-B-334919.
- the rollers of a pair of rollers rotate in opposite directions and at different speeds in order to shred and Grinding grain grinder to achieve.
- the roller gap can usually be varied
- DEAS 1 107033 describes a combined V-belt and timing belt with one toothed and one wedge-shaped side of the belt, which runs between three toothed belt pulleys and which still drives an outer V-belt pulley
- a similar solution is described in DE-A-3304832 for a roller mill.
- a double-sided toothed belt runs around the pulleys of the rollers and continues to run around a toothed belt pulley of the drive and an idler pulley
- Another Zahn ⁇ emenubert ⁇ eb is also known using Keil- Zahn ⁇ emen according to ITPS 1 198054 and EP-B-425626 the latter describes a roller mill with at least one pair of rollers, the shaft of the slower running the roller carries a disc which has teeth with grooves parallel to the axis and which contains a drive device which is held under tension by a third traction sheave which is adjustable in its position. The entire disc can be adjusted using set screws or eccentrics.
- the faster running roller is also provided with a disc that has teeth with grooves, although these are arranged at right angles to the shaft axis.
- the drive device itself is an externally and internally profiled belt which fits into the profiles of the aforementioned three disks, ie with a tooth or wedge profile.
- the pulleys are so wide that usually three belts are placed in parallel. These are tensioned together according to the aforementioned prior art and wear unevenly. Uniform clamping is very complex and not completely possible. Even reading and measuring beforehand cannot solve the problems.
- the invention is therefore based on the object of avoiding the disadvantages of the prior art as far as possible and of achieving uniform tensioning of the individual belts and thus also uniform wear.
- a pulley (tensioning pulley) is therefore designed to be divided so that the belts can be tensioned individually. This pulley is preferably divided in two.
- FIG. 1 shows a schematic illustration of a roller overlay.
- FIG. 2 shows the overdrive in the roller package.
- a deflection or tensioning roller 8 with a disc 18 two is also provided
- Commercial belts 9 profiled on both sides run around the pulleys 5, 6 and 18.
- the belts 9 preferably have an inside with a multi-wedge profile in the longitudinal direction and on the outside a tooth profile transverse to the longitudinal direction
- the disk 18 of the tensioning roller 8 has separately adjustable sections 1, 15, the inner section 14 being adjusted by means of a screw 13 and the outer section 15 using an eccentric 19.
- the eccentric 19 is fixed via a nut 17.
- a screw 16 fixes a shaft The tension can thus be optimized for each belt 9 in order to achieve a uniform overdrive or torque transmission or wear of the same type.
- Sections 14, 15 are preferably held by roller bearings 20
- rollers of a pair 3, 4 and 3, 4 ' are arranged in a so-called roller package, as described in DE-C-2730166 1
- This roller package is arranged in a manner not shown in detail on a base of the housing 2.
- the grinding gap setting device 12 is at the same time designed as a foreign body or overload protection device In such a roller mill 1, which is mainly used in milling, the rollers of a pair run against one another at different speeds and a specific roller gap. This means that not only pressure, but also friction and shear can be exerted on the regrind.
- a main drive, not shown, on one side of the roller mill 1 drives one of the two rollers of the pair directly, generally the faster roller 4, 4 '.
- the slower roller 3, 3 ' is pulled over the product by the faster roller 4, 4' during the grinding process.
- an overdrive (belt 9) with different pulley diameters is used. Since the rollers of the pair rotate in opposite directions, the pulley 5 must be arranged outside the belt 9. Due to the adjustable roller gap (and thus also the axial spacing of the rollers), a tensioning roller 8 must be provided. Accordingly, the disc 5 is provided with a tooth profile, parallel to the axis of the roller 3 (3 ').
- the disks 6 and 18, on the other hand have a flat profile or a wedge-groove profile in the circumferential direction or a tooth profile perpendicular to the axis of the roller 4 (4 '). Pulley and belt profiles are matched to each other. There is a positive connection between the pulley 5 and the belt 9 and between the belt 9 and the pulley 6 or 18 friction or frictional connection.
- Such an arrangement can be transferred analogously to the other pair of rolls and also to an 8-roll mill according to EP-B-334919.
- the invention is not limited to the illustrated embodiment.
