[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The utility model combines a driving motor, a spiral blade, an extrusion cone, a conical extrusion bucket and a lower hopper. By starting the driving motor to drive the driving shaft to rotate, the spiral blade is driven to rotate, and then the pigment can be added between the extrusion cone and the conical extrusion bucket. The pigment can be extruded in coordination with the rotation of the extrusion cone and then enters the mixing barrel to be fully mixed by the rotation of the stirring rod. Thus, the pigment can be mixed while being extruded, which is more convenient. In addition, the rotation of the spiral blade can feed the pigment following the rotation of the extrusion cone. At the same time, the spiral blade shields the lower hopper's lower feeding port, thereby preventing the pigment from splashing when it is extruded. This not only avoids waste caused by pigment dust splashing, but also prevents injuries caused by inhalation of pigment dust by personnel.

DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0018] Example 1: Pigment mixing device based on extrusion and stirring mechanism, see Figures 1 to 3 , including a mixing barrel 1, the top of the mixing barrel 1 is connected with a conical extrusion bucket 2, the top of the conical extrusion bucket 2 is connected with a cylinder 3, the inner cavity of the cylinder 3 is fixedly connected with a lower hopper 31, a driving motor 13 is installed at the bottom of the mixing barrel 1, the driving end of the driving motor 13 is fixedly connected with a driving shaft 14, the driving shaft 14 rotates through the mixing barrel 1 and is placed inside the mixing barrel 1, the top of the driving shaft 14 is fixedly connected with an extrusion cone 21, the top of the extrusion cone 21 is installed with a connecting shaft 32, the connecting shaft 32 is placed in the lower hopper 31, the outer side of the connecting shaft 32 in the lower hopper 31 is fixedly connected with a spiral leaf 33, the spiral leaf 33 is a rubber leaf, the outer side of the spiral leaf 33 is arranged in contact with the inner wall of the lower material port of the lower hopper 31, the outer side of the driving shaft 14 in the mixing barrel 1 is fixedly connected with a stirring rod 15, the mixing barrel The bottom side of 1 is connected with a discharge pipe 12, and a valve is installed in the discharge pipe 12. The four corners of the bottom of the mixing drum 1 are fixedly connected with support legs 11. By starting the drive motor 13, the drive shaft 14 is driven to rotate, thereby driving the spiral blade 33 to rotate, and then the pigment can be added between the extrusion cone 21 and the conical extrusion bucket 2, so that the pigment can be extruded after the rotation of the extrusion cone 21 and enter the mixing drum 1 to be fully mixed by the rotation of the stirring rod 15, so that the pigment can be extruded and mixed at the same time, which is more convenient. In addition, due to the rotation of the spiral blade 33, the pigment can be added following the rotation of the extrusion cone 21. At the same time, the spiral blade 33 blocks the discharge port of the discharge hopper 31, thereby avoiding dust splashing when the pigment is extruded, not only avoiding waste caused by pigment dust splashing, but also avoiding injury caused by inhalation of pigment dust by personnel.

[0019] For details, see Figure 2 A filter disc 16 is fixedly connected to the inner wall of the mixing barrel 1 above the stirring rod 15, and a grinding plate 17 is installed on the driving shaft 14 above the filter disc 16. When the pigment is squeezed into the mixing barrel 1, the squeezed pigment is placed on the filter disc 16, and the grinding plate 17 can rotate in a circle with the driving shaft 14, so that the squeezed pigment can be secondary crushed and then filtered, thereby improving the effect of pigment crushing.

[0020] For further information, see Figure 2The top of the extrusion cone 21 is fixedly connected with a truncated cone 22, and the connecting shaft 32 is fixedly connected to the top of the truncated cone 22. Through the setting of the truncated cone 22, the added pigment can be guided between the extrusion cone 21 and the blood return extrusion bucket to avoid the pigment being placed on the top of the extrusion cone 21 and unable to be extruded.

[0021] During operation, the pigment to be extruded and stirred is added into the lower hopper 31, and then the driving motor 13 is started to drive the driving shaft 14 to rotate, thereby driving the spiral blade 33 to rotate, and then the pigment can be added between the extrusion cone 21 and the conical extrusion hopper 2, so that the pigment can be extruded and enter the mixing barrel 1 in cooperation with the rotation of the extrusion cone 21. When the pigment enters the mixing barrel 1 after being extruded, the extruded pigment is placed on the filter disc 16, and the grinding plate 17 can follow the driving shaft 14 to rotate in a circle, so that the extruded pigment can be secondary crushed and filtered, thereby improving the effect of pigment crushing, and then the stirring rod 15 is rotated to fully mix the pigment, so that the pigment can be extruded and secondary crushed and mixed at the same time, and because the spiral blade 33 rotates, the pigment can be added following the rotation of the extrusion cone 21, and at the same time, the spiral blade 33 blocks the discharge port of the lower hopper 31, thereby avoiding dust splashing of the pigment during extrusion, which not only avoids waste caused by pigment dust splashing, but also avoids injury caused by pigment dust being inhaled by personnel.
