Embodiment 1

[0043] A kind of powder mixer is recorded, and the powder mixer is a powder metallurgy friction material mixer that can realize the function of segmented feeding, such as Figure 1 to Figure 3 As shown, the powder mixer includes:

[0044] A mixing bin 1, the mixing bin 1 is provided with a feed port 8 for the powder metallurgy friction material to enter;

[0045] The main screw reamer 2 is arranged in the mixing bin 1 and is driven to rotate along its circumferential direction. The first variable speed drive mechanism 3 is connected with the main screw reamer 2 to drive the main screw reamer 2 Variable speed rotation; the pitch value of the part of the helical main reamer 2 close to the feed port 8 is greater than the pitch value of the part of the helical main reamer 2 far away from the feed port 8 . Moreover, the pitch value of the helical main reamer 2 gradually increases toward the direction close to the feed port 8; because the feed port 8 must be set on the mixing bin 1...

Abstract

The invention discloses a powder blender mixer. The powder blender mixer comprises a mixing bin, a spiral main reamer and an auxiliary reamer, wherein the spiral main reamer is arranged in the material mixing bin, and is driven to rotate in the circumferential direction of the material mixing bin, a first variable speed driving mechanism is connected with the spiral main reamer, and drives the spiral main reamer to rotate at a variable speed; and the auxiliary reamer is arranged on the side part of the spiral main reamer, the reamer head of the auxiliary reamer is arranged towards the spiral main reamer, a second variable speed driving mechanism is connected with the auxiliary reamer, and drives the auxiliary reamer to rotate at a variable speed. According to the powder blender mixer, thespiral main reamer and the auxiliary reamer are controlled respectively, and the problems that in an existing blender mixer, the integrity of materials, such as natural graphite, can be affected in the process of material mixing, and mixed powder materials are further mixed unevenly can be effectively overcome.

Description

technical field [0001] The invention relates to the technical field of powder processing equipment, in particular to a powder mixer. Background technique [0002] The powder mixer is a machine with a shaft with blades rotating in a cylinder or a tank to stir and mix various raw materials to make it a uniform mixture. In particular, for the field of powder metallurgy brake pads, the powder metallurgy brake pads need to be made by mixing a variety of raw material powders and additive powders uniformly before pressing and sintering. However, powder metallurgy friction materials need to use easily broken natural graphite in the mixing process. It is difficult for existing powder mixers to ensure the integrity of natural graphite on the premise of ensuring a good mixing degree of raw material powder. [0003] Prior art such as the patent document with publication number CN206253027U discloses a gas convection type high-efficiency powder horizontal mixer, including a frame, a st...
