Problems solved by technology

At the same time, there are also some disadvantages: large heat is easily generated between the rotor stator and the material, the working temperature is high, and the material is easily denatured; the working surface of the grinding head is easy to wear, and after wear, the refining effect will be significantly reduced; Due to the different viscous materials, the flow rate varies greatly

Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0031] like figure 1 and figure 2 As shown, a kind of colloid mill grinding head bionic design method based on bovine molar geometric feature provided by the invention comprises the following steps:

[0032] S1. Obtain the point cloud data of the complete bovine molar surface.

[0033] In this embodiment, a high-precision three-dimensional scanner is used to perform three-dimensional scanning on mature and complete bovine molars to obtain point cloud data of the complete molar surface. The point cloud data of the complete bovine molar surface is obtained by scanning the complete permanent dentition of mature cattle with a growth time of more than four years. The crown characteristics of the permanent dentition of mature cattle are relatively complete, which makes the data required for bionics more accurate.

[0034] S2. Preprocessing a large amo...

Abstract

The invention discloses a bovine-molar geometric-feature-based biomimetic design method of a colloid-mill grinding head. Mature and complete bovine dentition is selected, point cloud data of the bovine dentition are acquired through three-dimensional laser scanning, and reverse-engineering software is used to reconstruct a three-dimensional bovine-tooth model; bovine-molar macroscopic-geometric-shape obtained by scanning is analyzed, and finite-element simulation is carried out on a molar chewing process through finite elements to determine tooth-ridge features on molars; and molar tooth-ridgefeature parameters are extracted and characterized, levels of extracting the feature parameters are reasonably selected according to a grinding-head design principle and an actual machining case, a corresponding orthogonal test scheme is designed, and thus the optimal biomimetic grinding head is obtained by optimization design. The grinding head can effectively reduce working temperature and action resistance of a colloid mill, and improve material crushing efficiency and service life thereof.

Description

technical field [0001] The invention belongs to the technical field of reverse engineering and bionic design, and in particular relates to a bionic design method for a grinding head of a colloid mill based on the geometric characteristics of bovine molars. Background technique [0002] With the development of our country's crushing and processing industry, colloid mills, as a kind of ultrafine pulverizing equipment for grinding colloidal or similar colloidal materials, are gradually recognized and used by people. At present, they have been widely used in food processing, architectural coating processing, plastic Industry, daily cosmetics, chemical industry, pharmaceutical processing, printing, paper industry, paint and other industries. The colloid mill has been identified as one of the best processing machinery and equipment in the crushing and processing industry in people's gradual understanding and use. It has the mechanical properties of various mixers, pulverizers, an...
