Example Embodiment

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, which are explained by the present invention and not limiting.

[0035] The method of the present invention is like figure 1 As shown, including:

[0036] S1: According to the change in the reference length direction, select the integration calculation or discrete calculation of the ratio of the integrated or discrete calculation; if the straight toothed parameters are constant in the direction of the reference length, and the mill Full-grubble, strategic selection of integral calculation or discrete calculation; if the straight toothed parameter is constant in the direction of the reference length, the partial wear area is not arranged, and the grinding is calculated. Select discrete calculation; if the straight toothed element is changed in the direction of the reference length, the discrete calculation is selected by the grinding cutting length;

Abstract

The invention discloses a method for calculating the cutting length of grinding teeth of grinding equipment provided with straight tooth elements, and belongs to the technical field of mechanical design and manufacturing. Firstly, according to whether tooth type parameters of a straight tooth element change in the reference length direction or not and whether a grinding area is full of grinding teeth or not, a discrete formula or an integral formula for grinding tooth cut-off length calculation is selected; and then selecting a cut-off length calculation formula suitable for different devices for calculation according to the device types. The method is suitable for calculating the cut-off length of the grinding teeth of equidistant straight tooth grinding discs of various structures and various devices provided with straight tooth elements, and the cut-off length of the grinding teeth is reasonably calculated according to the physical definition of the cut-off length of the grinding teeth, so that the actual requirements are met; meanwhile, the method is clear in calculation process and convenient to use, parameterized calculation of the grinding tooth cut-off length can be achieved, the grinding tooth cut-off length serves as a key parameter of strength characterization of the pulping process, and an important theoretical basis is provided for design and improvement of pulping equipment and optimization control of the pulping process.

Description

technical field [0001] The invention belongs to the technical field of mechanical design and manufacture, and in particular relates to a method for calculating the cut-off length of grinding teeth equipped with straight-tooth element refining equipment. Background technique [0002] The refining process is an important operation unit of pulping and papermaking, and papermaking reconstituted tobacco leaves, which can improve the properties of pulp and fibers, so as to adapt to the papermaking of paper with different properties. At present, the refining equipment used at home and abroad mainly includes disc refiner, conical refiner and cylindrical refiner. [0003] Straight tooth grinding disc is the most typical and widely used grinding disc in the pulping and papermaking process. Its tooth shape design is flexible and changeable, which can basically meet the refining process of various pulp conditions. Its application fields include not only pulping and papermaking, It also...
