Rolling mill for fine grinding chocolate, paint and the like. Patented in the German Empire on April 23, 1926.

The invention relates to a rolling mill for finely grinding chocolate, paint and the like is known in shot mills that one of two rollers is closed by weight levers stress that they are raised when a certain maximum resistance occurs can evade the weight. The subject matter of the invention is also a weight lever mechanism arranged; but has this

ίο the purpose of immediately releasing the pressure Exercise rollers, this is evenly distributed on all rollers. In contrast In addition to the known spring loading, the weight loading allows a much more uniform Setting and accurate measurement of the pressure. Furthermore, a lever can suddenly reduce the load on all rollers. and be turned off.

The sliding bearings of the movable rollers are finally connected to one another in such a way that the rollers in 20 = a certain adjustable distance from each other can be set, if that The rolling mill should not be used for fine grinding, but for mixing.

The drawing illustrates, for example, the invention, namely is

Fig. Ι a side view of an embodiment with a horizontal arrangement of the rollers, while

Fig. 2 is a side view and

Fig. 3 is a front view of a second embodiment with the vertical arrangement of the Rolling is.

The machine according to the example has three rollers, but it can also have four or more be. Both statements are correct up to

on the difference in the mutual position of the rollers and will therefore described together.

al ·, a ² and a? are the rollers, the gearbox is indicated with b; it works in a known manner with stepwise translation, so that each subsequent roller rotates faster than the previous one. The roller α ¹ is stationary, the others move with their ίο bearings m in guides formed on the machine frame, c is the pouring box and d is a scraper.

On the two frames of the machine frame, a lever g · and h are articulated on pins «, /. At the other end of the lever there is a movable joint head i or i ¹ , and these are each connected by a right-hand or left-hand threaded adjusting spindle k, which carries a handwheel ν. A pressure spindle I engages the lever with its fork head on each Hebei g . The spindle engages in the associated roller bearing m of the roller a ³ . Cams sitting on this bearing ?! carry rods o. A transverse piece p serving as a driver sits on the rods and is slidable and lockable by screws.

q is a continuous wave, which two

R contributes thumb and on which a reversing lever sits ί, which runs to a guided tour and can be found anywhere on her.

The guide is provided with a division.

The thumbs r reach under the levers h; the latter carry the pressure load t, which can be set up in different sizes depending on the number of plates and which causes a measurable roller pressure. When it has been tried out in the factory which load corresponds to the required working pressure (overstressing would be useless waste of strength), the setting of the lever mechanism has been found for permanent.

The. The machine can work on both fine grinding and mixing. For the former, the rollers are close to one another, with the set pressure being evenly distributed across all rollers. The lifter p is clamped a little behind the bearings of the roller a ² . The disengagement of the machine, ie the relief of the rollers, is only done by turning the lever s, but with one roller after the other. The thumbs r lift out the pressure weights, and at the same time the roller a "is moved outwards via the spindles k and lever g . It takes the rods υ with it, and after the lifter ρ has advanced accordingly, the latter lifts the roller a ² , which is thus from the roller moves away · al. the re-queuing is done in the reverse order.

For mixing work, the rollers should have a certain fixed distance between them, first getting bigger and then getting smaller. The changeover to this mode of operation takes place again only in one go using the lever ί. As when disengaging the first roller is taken cfi, the roller is a ² to the required distance to a nachgerückt ^s p by adjusting the lifter, while at the same time moved up from the roller · al. Apart from the presetting of the lifter p , the size of the spacing is only regulated again by the lever in connection with the division, because the distance it is allowed to cover in each case on the division determines the roller spacing.

■ The spindle k with the handwheel υ is mainly used to readjust the rollers when they have worn out.

Claims (4)

80 claims: 1. Rolling mill for fine grinding of chocolate, paint and the like, characterized in that a weight lever mechanism (g, k, h, t) ^{engages the sliding bearings of the last (α 3} ) of the movable rollers, and that with these sliding bearings those of the others movable rollers are connected with play that when the weight lever system is switched on, the pressure on all rollers is evenly distributed and when switched off, the rollers are lifted from one another one after the other. 2. Rolling mill according to claim 1, characterized in that the switching lever (s) used to switch the weight lever mechanism on and off is adjustable in various intermediate stages in such a way that the rollers (al ·, α ² , α ⁸ ) are determined at measurable distances from one another can. 3. Rolling mill according to claim 1 and 2, characterized in that the sliding bearings of the movable rollers (α ² , α ³ ) are connected by tie rods (0) and an adjustable crosspiece (p) on them. 4. Rolling mill according to claim 1 to 3, characterized in that the Gewi lever mechanism is adjustable in itself to readjust the rollers when worn to enable. 1 sheet of drawings.
