[0058] A method for mixing plastic particles, applied to the above-mentioned mixing apparatus, the mixing method comprising the following steps: S1: Quantitatively add material into funnel 51; The second motor 61, the second electric telescopic rod 63, and the first electric telescopic rod 62 work together to control the two mounting shafts 68 to be inserted into the two third slots 55 respectively. At this time, the rod sleeve 64 is in a vertical state. By activating the second electric telescopic rod 63, the feeding assembly 5 is lifted, so that the support seat 52 is separated from the support platform 4. The required raw materials are added into the funnel 51. During the feeding process, as the amount of raw materials in the funnel 51 increases, its weight becomes heavier and heavier, and the compression degree of the fourth spring 69 increases. The length of the fourth spring 69 is obtained by the data detected by the distance sensor 610, and thus the weight of the raw materials in the funnel 51 can be determined. When the preset amount is reached, the feeding is stopped, and the feeding assembly 5 is placed back on the support platform 4 by retracting the second electric telescopic rod 63.

[0059] S2: Introduce raw materials into pool 21: The second motor 61, the second electric telescopic rod 63, and the first electric telescopic rod 62 work together to control the insertion of two mounting shafts 68 into the third insertion holes 585 on the two first limiting members 58. By extending the second electric telescopic rod 63, the limiting piece 583 is moved, thereby driving the first rotating shaft 584 to move and disengage it from the first fixing block 56. The second motor 61, the second electric telescopic rod 63, and the first electric telescopic rod 62 work together to control the movement of the discharge port of the discharge pipe 53, so that the first rotating shafts 584 on the two first limiting members 58 are respectively inserted into the two vertical sliding grooves. Inside 24, the second slot 54 faces downward. The first motor 34 and the first cylinder 316 work together to make the uppermost stirring rod 36 correspond one-to-one with the second slot 54. The second motor 61 is started to control the second electric telescopic rod 63 to rotate downward. Since the elastic telescopic component can automatically extend and retract, the first rotating shaft 584 moves vertically within the vertical slide 24 under the restriction of the vertical slide 24. Finally, the first rotating shaft 584 enters the annular slide 23, the upper stirring rod 36 is inserted into the second slot 54, and then the weighing component 6 is removed from the pool body 21.

[0060] By starting the first motor 34 to control the stirring rod 36 to make an arc-shaped movement, the first rotating shaft 584 is driven to move in an arc within the annular chute 23. As a result, the discharge port on the discharge pipe 53 moves in an arc towards the bottom of the pool body 21. During the movement, the raw material in the funnel 51 is introduced into the pool body 21. By adding material into the pool body 21 in this way, the problem of plastic particles floating on the surface of other materials and being difficult to mix with other materials due to their light weight can be avoided.

[0061] After feeding is completed, the discharge pipe 53 is removed from the pool 21 by the weighing component 6 and folded on one side of the funnel 51. Then, the first rotating shaft 584 is inserted into the first fixing block 56 to limit the discharge pipe 53.

[0062] S3: Mixing; The first motor 34 is started to control the rotation of the stirring rod 36 to stir the raw materials in the tank 21. During the stirring process, the first cylinder 316 is started to control the stirring rod 36 to move laterally, so that the stirring rod 36 can make a spiral motion, thereby improving the uniformity of material mixing.

[0063] S4: Discharge; The second motor 61, the second electric telescopic rod 63, and the first electric telescopic rod 62 work together to control the two mounting shafts 68 to be inserted into the two first slots 311 respectively. At this time, the drive plate 314 is squeezed by the pressure plate 67 and moves away from the second vertical plate 13, thereby driving the second sliding shaft 313 to move out of the first insertion hole 14. By starting the second motor 61, the second electric telescopic rod 63 is driven to rotate, which in turn drives the pool body 21 to rotate until the discharge nozzle 22 tilts downward, pouring out the material in the pool body 21 and realizing the discharge. This discharge method can increase the torque, reduce the force, and save energy compared to the method of directly fixing the drive source on the rotating shaft of the pool body 21.

[0064] S5: Clean the pool body 21; Insert the two mounting shafts 68 into the third insertion holes 585 on the two second limiting members 74 respectively, and then control the first rotating shaft 584 on the second limiting member 74 to insert into the annular slide groove 23. At the same time, the stirring rod 36 above is inserted into the fourth slot 73. By starting the first motor 34, the stirring rod 36 is controlled to rotate, which in turn drives the cleaning strip 72 to rotate. During the rotation, the bottom of the pool body 21 can be cleaned.
