During the rotation of the tooth plate 107, the drive seat 104 and the return spring 106 cause reciprocating motion up and down, thereby driving the gear 108 to rotate reciprocatingly, thereby driving the stirring blade 109 to swing back and forth, so that the stirring blade 109 makes a circular motion while swinging, thereby improving the stirring efficiency of the raw materials. It can be understood that the above-mentioned scheme can be used to improve the stirring efficiency of the raw materials in the stirring barrel 102, and can also be used to facilitate the placement of the raw materials inside the stirring barrel 102.

The lower surface of the driving seat 104 is provided with a plurality of protrusions, and the tooth plate 107 is driven to move upward by the elasticity of the return spring 106, so that the upper end of the tooth plate 107 is moved upward. When in use, plastic particles and other auxiliary materials are added through the feed port on the mixing barrel 102, and then the rotating member 110 is started to drive the housing 105 to rotate. During the rotation of the housing 105, the tooth plate 107, the gear 108 and the stirring blade 109 are driven to rotate, so that the stirring blade 109 performs a circular motion, thereby stirring the raw materials in the mixing barrel 102; when the tooth plate 107 rotates to the protrusion on the driving seat 104, the tooth plate 107 moves downward under the action of the protrusion on the driving seat 104 and squeezes the return spring 106 Since the gear 108 is meshed with the tooth plate 107, the gear 108 is driven to rotate during the downward movement of the tooth plate 107, and the gear 108 drives the stirring blade 109 to rotate. When the tooth plate 107 rotates to leave the protrusion on the driving seat 104, the tooth plate 107 is reset under the action of the reset spring 106, and the gear 108 and the stirring blade 109 are driven to reset, so that the stirring blade 109 can swing up and down during the circular motion, thereby stirring the raw materials inside the stirring barrel 102, thereby achieving the purpose of improving the stirring efficiency of the raw materials.

[0029] In addition, the seat body 117 is fixedly connected to the lifting plate 115 and is located on a side of the lifting plate 115 close to the driving seat 104; the rubber wheel 118 is rotatably connected to the seat body 117 and is arranged on the seat body 117; through the rotation of the rubber wheel 118, the friction between the abutment seat 114 and the driving seat 104 is reduced, thereby reducing the resistance when driving the outer shell 105 to rotate, making the rotation of the outer shell 105 smoother and reducing the generation of noise.

[0030] Then, the connecting plate 119 is fixedly connected to the gear 108 and is arranged on the gear 108; the swing plate 120 is fixedly connected to the connecting plate 119 and is located on one side of the connecting plate 119; a through groove is provided on the outer shell 105, so that the connecting plate 119 can extend out of the outer shell 105 to connect with the swing plate 120, and at the same time, the through groove prevents the outer shell 105 from interfering with the movement of the connecting plate 119 and the swing plate 120.

[0031] Finally, the two sides of the sealing sleeve 121 are respectively connected to the outer shell 105 and the swing plate 120, and the sealing sleeve 121 is sleeved on the connecting plate 119; the sealing sleeve 121 is made of rubber material and can be bent. The sealing sleeve 121 is used to seal the gap between the connecting plate 119 and the through groove on the outer shell 105 to prevent the raw materials from entering the outer shell 105 during the stirring process and affecting the transmission between the rack 116 and the gear 108.

[0032] When using the particle mixer of this embodiment, the raw materials are added through the feed port on the top of the mixing barrel 102, and then the rotating motor 113 is started to drive the connecting frame 112 to rotate, and the connecting frame 112 drives the three shells 105 to rotate, and then drives the gear 108, the connecting plate 119 and the swing plate 120 to rotate, so that the swing plate 120 performs a circular motion, and then the raw materials in the mixing barrel 102 are stirred; during the rotation of the shell 105, the lifting plate 115, the rack 119 and the gear 110 are driven to rotate. 116, the seat body 117 and the rubber wheel 118 rotate.
