Grinding machine for preparing powder coating

Abstract

The invention provides a grinding machine for preparing powder coating, which comprises a coarse material box, a finished product box, a barrel, an upper grinding disc and a lower grinding disc located below the upper grinding disc; the upper grinding disc is arranged on a rack through a vibration mechanism; scraping blades are arranged on the lower end face of the upper grinding disc and the upper end face of the lower grinding disc correspondingly; a feeding pipe and a discharging pipe are connected to the side wall of the barrel; a drainage fan is arranged in the discharging pipe, the drainage fan works to enable the interior of the barrel to be in a negative pressure state to suck materials into the barrel; the upper grinding disc and the lower grinding disc rotate reversely during grinding, the scraping blades stir the materials to move in the horizontal direction, and the upper grinding disc is arranged in an up-down vibration mode, downward pressure can be provided for the materials, the materials can move in the vertical direction, the materials can be ground automatically, the grinding effect and efficiency are improved, and compared with a screen filtering mode, the discharging mode that the materials are sucked out through the drainage fan after grinding is completed is higher in efficiency and free of blockage.

Description

technical field [0001] The invention relates to the field of powder coating production, in particular to a grinder for preparing powder coatings. Background technique [0002] Powder coating is a solid powder coating composed of solid resins, pigments, fillers and additives. It has the characteristics of no solvent, no pollution, saving energy and resources, reducing labor intensity and mechanical strength of the coating film. In the preparation process of powder coatings, there are many processes including extruding, tableting, crushing, grinding, etc. In the traditional grinding process, the materials are generally loaded manually, and the ground fine materials are collected by setting sieve holes on the grinding disc. Discharge, this method has a large workload and high labor costs, and it is easy to cause blockage of the screen holes after a long time of work, which affects work efficiency. Contents of the invention [0003] The technical problem to be solved by the p...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that in the traditional technology, in the traditional grinding process, materials are generally manually loaded, and the ground fine materials are discharged by setting sieve holes on the grinding disc. This method has a large workload and relatively high labor costs. high, and it is easy to cause blockage of the screen hole after working for a long time, which affects work efficiency. The invention provides a grinding machine for preparing powder coatings to solve the above problems
