Definitions
- the invention relates to a rolling mill with a doctor blade and in particular to a five-roll mill with a doctor blade on the last roll.
- the known stripping mechanism used in this case contains three components: a knife bar, a knife holder and the actual doctor blade or "knife".
- a knife a spring steel strip is usually used, which is supplied on rollers and as required (for example, rolling length of the rolling mill) is cut off from the roll in the appropriate length.
- the life of the knife depends on the type of product to be processed, which must be stripped from the roll. The higher the cocoa content of the cocoa mass or chocolate mass, the faster the knife wears off due to abrasion.
- the invention has for its object to provide a quick-change and easy to handle stripping system for a five-roll mill.
- This object is achieved by a stripping system for stripping product from a roll in a rolling mill, in particular at the last roll in a five-high rolling mill, with a knife bar, a knife holder and a doctor blade, which rests against the roller with the product to be stripped.
- the knife holder has a spring-loaded knife clamping system.
- the spring-loaded blade clamping system has a double-spring system, which has a coil spring and / or a plate spring.
- a double-spring system which has a coil spring and / or a plate spring.
- the variant with coil spring / disc spring combination is particularly preferred.
- the spring-loaded knife clamping system has a lever system for clamping the knife.
- a lever system for clamping the knife is particularly preferred here.
- a toggle lever system is particularly preferred here.
- the angle of attack of the blade on the roller is greater than 45 °, more preferably greater than 55 °. Due to this "high knife guidance", the amplitudes of the knife vibration can be kept very small.
- the knife clamping system has a plurality of lever systems, which are expediently arranged at different locations of the clamping system distributed along the length of the knife or along the length of the roll. They can be arranged uniformly spaced along the clamping system.
- the plurality of lever systems are arranged along the clamping system at the locations of the largest vibration deflections of the cutter bar.
- the knife can be mounted on several pins. This reduces the accumulation and adhesion of dirt on the knife position. A cleaning of the clamping system when changing blades is therefore unnecessary. Above all, the combination of the two measures for reducing the amplitude of the knife vibration (high angle of attack) and the cutter bar vibration (clamping system in each case in the case of the vibration bars of the cutter bar) proves to be very beneficial.
- Fig. 1 shows an inventive stripping system with clamping system.
- FIG. 2 is an end view of a stripper system according to the invention along the longitudinal axis of the blade 1 (rollers not shown).
- FIG. 2 is an end view of a stripper system according to the invention along the longitudinal axis of the blade 1 (rollers not shown).
- FIG. 3A, 3B, 3C, 3D show a lever system of a knife clamping system according to the invention in several positions: FIG. 3A: System open; FIG. Fig. 3B: jaw adjacent; Fig. 3C: toggle at dead center; and Fig. 3D: System closed.
