Specific embodiment
Below, with reference to accompanying drawing and specific embodiment, the utility model is described further:
Embodiment 1
As shown in Figure 1-2, a kind of powdery paints bonding machines agitating paddle, including rotary shaft 10 and it is fixed on from top to bottom
Upper agitating paddle 20, middle agitating paddle 30 and lower stirring paddle 40 in the rotary shaft 10, the quantity of the middle agitating paddle 30 are not limited to one
Branch, can there is branched, be described in detail in case of middle agitating paddle 30 has two below.
Upper agitating paddle 20 includes two centrosymmetric first blades 21 stretched out by the surface of rotary shaft 10;
Middle agitating paddle 30 include above first in agitating paddle 32 in agitating paddle 31 and underlying second;First
Middle agitating paddle 31 includes two centrosymmetric second blades 311 stretched out by the surface of rotary shaft 10;Agitating paddle in second
32 include the two centrosymmetric third blades 321 stretched out by the surface of rotary shaft 10.
Lower stirring paddle 40 includes the two centrosymmetric quaterfoils 41 stretched out by the surface of rotary shaft 10;Lower stirring
Oar 40 is provided with the edge sealing 42 positioned at the top of quaterfoil 41, and the edge sealing 42 is from the surface of rotary shaft 10 to the direction of both sides quaterfoil 41
Extend, and edge sealing 42 length of the length less than quaterfoil 41, the upper surface of edge sealing 42 is vertical with rotary shaft 10.Preferably,
Edge sealing 42 is the 1/2 of the length of quaterfoil 41 along the length that quaterfoil 41 extends.The setting of edge sealing 42 can reduce lower stirring
Oar 40 provides upward thrust near the part of rotary shaft 10 to powder.
The first blade 21, angle between quaterfoil 41 and rotary shaft 10 is acute angle;And first blade 21 and powder
Acting surface be lower surface, the acting surface of quaterfoil 41 and powder is upper surface;Such structure setting so that agitating paddle
During stirring, can be pressed downward for powdery paints by upper agitating paddle 20, and lower stirring paddle 40 can upwards boost powdery paints.Preferably,
One blade 21, quaterfoil 41 is in 45 ° of angle with rotary shaft 10.
Second blade 311, third blade 321 be used for powder is frictionally heated, the second blade 311, third blade 321 with rotation
