High-molecular coating raw material grinding device

Abstract

The invention discloses a high-molecular coating raw material grinding device. The high-molecular coating raw material grinding device is characterized by structurally comprising an equipment base, adrive motor, a discharge barrel, an uniform contact system, a regulating disc, a charge hopper and a reflow tube. The high-molecular coating raw material grinding device has the beneficial effects that: a material springing mechanism is matched with an uniform grinding mechanism for favorably realizing that internal external-force springing is performed in grinding high-molecular coating raw materials to avoid a phenomenon that skin formation appears on the upper parts of the high-molecular coating raw materials during grinding. A uniform grinding structure is arranged for performing manual-operation type external force extruding crushing effect on relatively great granular high-molecular coating raw materials which are ground insufficiently and block surfaces of mesh holes, so that sufficient grinding on the high-molecular coating raw materials is realized, and a blockage phenomenon of raw materials in the mesh holes is avoided.

Description

technical field [0001] The invention relates to the field of grinding devices, more precisely, it relates to a grinding device for polymer coating raw materials. Background technique [0002] In the production and preparation process of polymer water-based coatings, the grinding of polymer coating raw materials is one of the important processes to ensure the quality of coatings. [0003] When using a grinding machine to grind polymer coating raw materials, since the polymer coating raw materials are mainly based on compounds, and various raw materials are mixed and prepared, when using a grinding machine to mix and grind them, due to their particle diameter The size is different, and heat energy will be generated during grinding, so that the polymer coating raw materials at the bottom will stick to each other, and the temperature of the upper and inner bottom raw materials will be inconsistent, making the upper raw materials more prone to conjunctiva phenomenon. If the size...

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a polymer coating raw material grinding device to solve the problem in the prior art that when using a grinder to grind the polymer coating material, since the polymer coating material is mainly based on The compound is the matrix, and various raw materials are mixed and prepared. Therefore, when the grinder is used for mixing and grinding, the particle diameters are different, and heat energy is generated during grinding, so that the polymer coating materials at the bottom appear to stick to each other. The upper part and the inner bottom of the material sense temperature are inconsistent, making the upper part of the material more prone to conjunctiva phenomenon, and due to the different particle diameters during grinding, the larger particle diameter will directly stay on the surface of the screen, resulting in grinding blockage defect
