The cutting portion 162 forms a "blade-like structure, thereby improving the shearing and dispersing ability of the second dispersing member 16 to the material to be stirred and improving the stirring effect and stirring efficiency of the stirring paddle 10. The cutting portion 162 may be provided on a side of the main body portion 161 facing the rotation direction of the rotation shaft 11. In some embodiments, the main body 161 is provided with the cutting portions 162 on two opposite sides of the turntable 12 along the circumferential direction Y, so that the cutting portions 162 can improve the shearing and dispersing ability of the second dispersing member 16 when the rotating shaft 11 rotates in the forward or reverse direction. In some embodiments, the end of the main body portion 161 facing away from the connector 15 is also provided with a cutting portion 162 to further enhance the shearing and dispersing ability of the second dispersion member 16.

It will be appreciated that the solid components in the material to be stirred are easily deposited on the bottom of the kneading barrel 20 due to the influence of gravity, the protruding height of the second dispersing element 16 relative to the first surface 151 is greater than the protruding height relative to the second surface 152, so that the distance between the stirring paddle 10 and the bottom of the kneading barrel 20 can be reduced, the first dispersing element 14 and the second dispersing element 16 can better shear and disperse the material to be stirred, the uniformity of dispersing the components in the material to be stirred is improved, and the stirring quality is improved. Wherein the second dispersion member 16 may be arranged through the connection member 15. The second dispersing member 16 and the connecting member 15 may be integrally welded to improve the stability of the connection of the second dispersing member 16 to the connecting member 15. In some embodiments, the second dispersing member 16 and the connecting member 15 may be further fastened together by a snap fit, a screw fit, or the like. In some embodiments, the second dispersion member 16 may also be disposed only on the first surface 151 or the second surface 152 to reduce the overall weight of the paddle 10 and thereby increase the rotational speed of the paddle 10.

Referring to fig. 2 and 4, the second dispersing member 16 extends in an arc shape. In the present embodiment, a plurality of second dispersing members 16 are provided on at least one of the connecting members 15, and all of the second dispersing members 16 extend in the same direction as the circumferential direction Y of the turntable 12. The second dispersing members 16 are disposed in an annular spaced relationship about the central axis of the rotary shaft 11. In some embodiments, the second dispersion member 16 may be elongated in a straight line, wave, dog bone, etc.

The plurality of second dispersing members 16 includes a first sub-dispersing member 1601 and a second sub-dispersing member 1602. The first sub-dispersion member 1601 is spaced from the central axis C1 of the rotation shaft 11 more than the second sub-dispersion member 1602 is spaced from the central axis C1 of the rotation shaft 11. The first sub-dispersion member 1601 has an extension length in the circumferential direction Y of the turntable 12 longer than the extension length of the second sub-dispersion member 1602 in the circumferential direction Y of the turntable 12. It can be understood that, when the stirring paddle 10 rotates, the greater the distance from the central axis C1 of the rotating shaft 11, the greater the corresponding linear velocity of the second dispersing member 16, and the greater the impact force of the material to be stirred, therefore, by increasing the extension length of the second sub-dispersing member 1602, the structural strength of the second sub-dispersing member 1602 can be improved, so that the second sub-dispersing member 1602 is not easy to break, and the dispersing capability of the second sub-dispersing member 1602 can be improved, thereby improving the use reliability and stirring efficiency of the stirring paddle 10.

Referring to fig. 9, in some embodiments, the extending direction of at least one second dispersing member 16 of the plurality of second dispersing members 16 is different from the circumferential direction Y of the turntable 12, so as to increase the contact angle between the second dispersing member 16 and the material to be stirred, and enable the second dispersing member 16 to stir the material to be stirred better when shearing and dispersing the material to be stirred, so that each component in the material to be stirred is dispersed uniformly, thereby improving the stirring effect and stirring efficiency of the stirring paddle 10. The plurality of second dispersing members 16 may be disposed to extend obliquely toward a direction approaching or away from the rotating shaft 11 in the rotating direction of the rotating shaft 11. Among the plurality of second dispersing members 16, at least two second dispersing members 16 may have different deflection directions and deflection degrees with respect to the rotation shaft 11, or all the second dispersing members 16 may have the same deflection directions and deflection degrees with respect to the rotation shaft 11. The deflection direction and the deflection angle of the second dispersing member 16 relative to the rotating shaft 11 may be specifically set according to actual needs, and the present utility model is not limited thereto. Illustratively, the plurality of second dispersing members 16 may be disposed to extend obliquely in the rotation direction of the rotation shaft 11 toward a direction away from the rotation shaft 11. When the rotating shaft 11 drives the second dispersing member 16 to rotate, the second dispersing member 16 can drive the material to be stirred to move towards the direction close to the rotating shaft 11, namely, the material to be stirred moves along the radial direction of the rotating shaft 11 while rotating around the rotating shaft 11, so that the dispersion degree of each component in the material to be stirred is improved, and each component is uniformly dispersed.

Referring to fig. 10, in some embodiments, shear structures 163 are provided on the first and/or second dispersion members 14, 16. The shearing mechanism 163 may be configured as a raised or recessed groove protruding from the outer surface of the first dispersion member 14 and/or the second dispersion member 16. Wherein the protrusions may be configured as spherical protrusions, columnar protrusions, pyramidal protrusions, etc., and the grooves may be configured as spherical grooves, columnar grooves, bar grooves, tapered grooves, etc. The shear structure 163 may be capable of providing additional agitation force to the second dispersion member 16. When the material to be stirred is more viscous, the additional shear force provided by the shear structure 163 may reduce the resistance of the material to be stirred to the second dispersion member 16, thereby improving the stirring efficiency of the stirring paddle 10. When the material to be stirred is thin, the shearing structure 163 can also provide additional breaking force, which is beneficial to more fully stirring the material to be stirred. Illustratively, the shearing mechanism 163 is illustrated in fig. 10 as a spherical protrusion configured to protrude from the second dispersion member 16, which may protrude from the body portion 161 and/or the cutting portion 162. In some embodiments, the shear structure 163 may also be configured as a groove recessed in the second dispersion member 16. In some embodiments, the shear structure 163 may also be configured as a protrusion protruding from the first dispersion member 14 or a recess recessed from the first dispersion member 14.

Referring to fig. 2 and 11, the thickness of the connecting member 15 is smaller than the thickness of the blade 13 along the axial direction of the turntable 12.
