Molding powder bonding device

Abstract

The invention discloses a molding powder bonding device which comprises a reaction tank, a pedestal and a driving device, wherein the reaction tank comprises an agitating mechanism in a tank body; thetank body is a cylindrical container with an opening in the top; multiple layers of annular heat dissipation sheets are arranged in an inner barrel of the tank body; a material feeding opening is formed in a tank cover; an oxygen detector is arranged on the inner side of the tank cover; the agitating mechanism consists of a rotating shaft, and a first blade group, a second blade group, a third blade group and a fourth blade group which are connected to the rotating shaft in a sleeving manner from top to bottom; water cooling loops are arranged in agitating blades; a nitrogen passageway is formed in the reaction tank; and the driving device is a motor driving the rotating shaft to rotate through a belt transmission mechanism. The molding powder bonding device can guarantee a heating requirement during molding powder bonding, so that molding powder and pigment can be quickly bonded; the molding powder bonding device also can bring away residual heat to prevent a material from being blocked; and a nitrogen loop can guarantee safe production.

Description

technical field [0001] The invention relates to a plastic powder manufacturing device, in particular to a plastic powder bonding device. Background technique [0002] Plastic powder is the material of the plastic spraying process. Simply put, the plastic powder is sprayed onto the surface of the material by the wind (by electrostatic spray) after being heated at a high temperature. The effect of plastic spraying is good, the cost is low, the color is positive, and it is beautiful. Plastic powder is a thermosetting powder for electrostatic spraying, which contains solid resin for coating, pigments, fillers, additives and other ingredients. Plastic powder binding is to heat the resin powder base to a temperature slightly lower than the softening point of the resin. At this time, the working state should be that the surface of the resin powder base melts, while the inside of the resin powder base is still in a solid state. At this time, let the pigment powder particles It is ...

AI Technical Summary

Problems solved by technology

If the binding temperature is higher than the critical temperature, the surface layer of the resin powder base will not melt enough, resulting in the pigment powder not being able to bind to the resin powder base is not strong enough; if the binding temperature is higher than the critical temperature, it will cause the entire resin powder base to melt and bond In a group, the binding cannot be achieved
