Specifically, during the mixing process, the first link 121 and the second link 123 of the stirring mechanism perform the following stirring operations:
(1) when the vertical rod 115 moves around, because of the first annular rail 130 formed by the feeding cylinder 110 and the helical gear stage 132 processed by the first annular rail 130, when the first connecting rod 121 moves around relative to the feeding cylinder 110 along with the vertical rod 115, the first helical gear 133 of the first short shaft 136 connected with the first connecting rod 121 is meshed with the helical gear stage 132 in the first annular rail 130, so that the first connecting rod 121 drives each L-shaped blade 122 on the side to rotate, and the width of the first annular groove 135 is smaller than the particle size of the particle material, so that the particle material cannot enter the first annular rail 130 through the first annular groove 135 to cause clamping teeth;
(2) when the vertical rod 115 moves around, the second connecting rod 123 is rotationally sleeved with the first connecting rod 121, so that when the first connecting rod 121 moves around relative to the feeding barrel 110 along with the vertical rod 115, the same second connecting rod 123 moves around relative to the mixing barrel 100 along with the first connecting rod 121, and due to the second annular rail 131 formed by the mixing barrel 100 and the helical gear table 132 processed by the second annular rail 131, the second helical gear 134 of the second short shaft 138 connected with the second connecting rod 123 is engaged with the helical gear table 132 in the second annular rail 131, so that the second connecting rod 123 drives each strip-shaped blade 124 on the side to rotate, and the width dimension of the second annular groove 137 is smaller than the particle size of the particle material, so that the particle material cannot enter the second annular rail 131 through the second annular groove 137 to cause clamping teeth;
(3) in addition, since the up-down directions of the helical gear platforms 132 processed by the first annular rail 130 and the second annular rail 131 are opposite, in this embodiment, the helical gear platform 132 in the first annular rail 130 is at the lower side, and the helical gear platform 132 in the second annular rail 131 is at the upper side, so that the rotation directions of the first connecting rod 121 and the second connecting rod 123 are opposite, and in the stirring process of each stirring mechanism, the stirring directions of the raw materials in the mixing barrel 100 are more changeable and the mixing effect between the plastic particles and the raw materials such as color masterbatch is better through the reverse rotation of the L-shaped blades 122 and the strip-shaped blades 124.

When the motor 103 is started, the output shaft of the motor 103 drives the first external gear ring 140 to rotate, because the first external gear ring 140 is meshed with the first transmission gear 143 at the upper end of each transmission shaft 141, each transmission shaft 141 synchronously rotates along with the output shaft of the motor 103, and because the second transmission gear 144 at the lower end of each transmission shaft 141 is meshed with the second external gear ring 142 of the connecting frame 114, when each transmission shaft 141 rotates, the second external gear ring 142 and the connecting frame 114 are driven to rotate, and therefore after the motor 103 is started, the connecting frame 114 can synchronously rotate with the output shaft of the motor 103.

In embodiment 2, on the basis of embodiment 1, although the technical solution in embodiment 1 can convey the raw materials of the conical shell upwards for mixing, the raw materials fall only on one side close to the feeding cylinder 110 when falling, so that the raw materials fall unevenly, in order to further improve the mixing effect, as shown in fig. 5 to 7, a distributing platform 200 is further installed at the top of the feeding cylinder 110, the upper surface of the distributing platform 200 is processed into a smooth arc surface, the distributing platform 200 is provided with a plurality of distributing openings 201 respectively corresponding to the transmission shafts 141, and a dispersing mechanism is further arranged below the distributing openings 201 by the transmission shafts 141;
the dispersing mechanism comprises a conical centrifugal hopper 210 and a circular ring cover 211, the conical centrifugal hopper 210 is fixedly connected with the lower side of the transmission shaft 141, the circular ring cover 211 is fixedly connected with the bottom of the material distributing platform 200 and is positioned above the conical centrifugal hopper 210, the transmission shaft 141 is positioned in the middle part of the inner side of the circular ring cover 211, and the material distributing opening 201 corresponds to the inner side of the circular ring cover 211;

When the spiral feeding mechanism conveys the raw materials to the top of the feeding cylinder 110 and overflows, the raw materials can directly enter the material distributing platform 200, and meanwhile, the upper surface of the material distributing platform 200 is processed into a smooth cambered surface, so that the raw materials in the material distributing platform 200 are uniformly led out to each material distributing opening 201;
since the material distributing opening 201 corresponds to the inner side of the circular ring cover 211, the raw materials led out from the material distributing opening 201 can directly enter the conical centrifugal hopper 210 through the gap between the circular ring cover 211 and the transmission shaft 141, and the gear ratio of the first outer gear ring 140 and the first transmission gear 143 is not less than 5:1, so that when the output shaft of the motor 103 rotates, the rotation speed of each transmission shaft 141 increases to not less than 5 times of the rotation speed of the output shaft of the motor 103, and the conical centrifugal hopper 210 connected with the transmission shaft 141 rotates at high speed;
after the raw materials enter the conical centrifugal hopper 210 rotating at a high speed, the centrifugal force generated by each raw material particle is different due to the different weights of the raw materials of the particles such as plastic particles, color master particles and the like, so that each raw material particle presents different flowing states in the centrifugal hopper 210, preliminary centrifugal mixing is realized, each raw material particle is finally separated from the conical centrifugal hopper 210 and thrown out under the action of centrifugal force, and the thrown out raw material particle directly collides with the annular cover 211 above the conical centrifugal hopper 210;
