[0027] Embodiment: a kind of plastic particle multi-station mixer, as shown in Figure 1 Figure 4 As shown, including mixing cylinder 1, motor 2 is arranged above mixing cylinder 1, stirring assembly 3 is rotationally arranged in the inside of mixing cylinder 1, feeding component 4 is inserted in the outer surface of mixing cylinder 1;
[0028] Stirring assembly 3 includes screw conveyor 301 rotationally arranged in the inside of mixing cylinder 1, broken rod 302 and stirring rod 304, broken rod 302 and stirring rod 304 are connected with screw conveyor 301 by annular support plate 6, a plurality of broken folding leaves 303 are installed on the outer surface of broken rod 302, broken folding leaf 303 is connected with motor 2 by meshing transmission component 5, two stirring paddles 305 are symmetrically installed on the outer surface of stirring rod 304.
[0029] When plastic particles of different types, colors, and properties enter the mixing drum 1 from the feeding assembly 4, the screw conveyor 301, the crushing and baffle 303, and the agitator 305 operate simultaneously. The screw conveyor 301 circulates the plastic particles from bottom to top, the crushing and baffle 303 rotates and stirs, crushing and agitating the plastic particles, and the agitator 305 rotates to further aid in the mixing of the plastic particles. Using the screw conveyor 301, crushing and baffle 303, and agitator 305, the screw conveyor 301 drives the plastic particles axially, causing them to circulate up and down inside the mixing drum 1, preventing accumulation at the bottom and ensuring the stability and continuity of the mixing process. The agitator 305 agitates the plastic particles axially, working in conjunction with the screw conveyor 301... 01, can drive particles to flow axially and radially, fully mixing plastic particles at different positions to achieve uniform mixing; under the action of the crushing and folding blade 303, it can break up the agglomerates formed by plastic particles during storage or transportation, ensuring the uniformity of mixing. At the same time, during the mixing process, the shearing and crushing action of the crushing and folding blade 303 on the plastic particles can continuously renew the particle surface, increase the contact area between particles, and enable different types of plastic particles to come into closer contact and mix, improving the mixing effect. With the cooperation of the screw conveyor 301, the crushing and folding blade 303 and the stirring blade 305, the plastic particles can be crushed and driven to move axially and radially, ensuring that the plastic particles are fully mixed during the mixing process and avoiding local uneven mixing.
[0030] like Figure 1 - Figure 4 As shown, the output end of motor 2 is rotatably connected to the upper surface of mixing cylinder 1, and the output end of motor 2 extends into the interior of mixing cylinder 1.
[0031] The upper end of the screw conveyor 301 is fixedly connected to the inner output end of the motor 2. The screw conveyor 301 is fixedly connected to the annular support plate 6.

The lower surfaces of two support plates located on the same horizontal plane are respectively rotatably connected to the crushing rod 302 and the stirring rod 304. The upper end of the crushing rod 302 extends out of the upper surface of the support plate.
[0032] The meshing transmission assembly 5 includes a driven gear 501 and a fixed gear 502, with the lower end of the driven gear 501 fixedly connected to the upper end of the crushing rod 302.

When the broken blades 303 rotate, the driven gear 501 is driven to rotate at the same time. Based on the meshing connection between the fixed gear teeth 502 and the driven gear 501, the driven gear 501 is driven to rotate, so as to drive the broken blades 303 to crush the plastic particles.
[0035] As shown in Figure 1 Figure 4 A plurality of broken blades 303 are located in the same vertical plane, and the outermost surfaces of the broken blades 303 and the stirring paddles 305 are not in contact with the outermost surfaces of the spiral conveyor 301 and the inner wall of the mixing cylinder 1.
[0036] The plurality of broken blades 303 located in the same vertical plane can increase the contact area between the broken blades 303 and the plastic particles, improve the uniformity of the crushing of the plastic by the broken blades 303, and avoid the mutual influence of the components under the condition that the outermost surfaces of the broken blades 303 and the stirring paddles 305 are not in contact with the outermost surfaces of the spiral conveyor 301 and the inner wall of the mixing cylinder 1, so as to ensure the stability and continuity of the operation of the device.
[0037] As shown in Figure 1 Figure 4 The feeding assembly 4 is composed of a plurality of feeding grooves, and a plurality of feeding openings are uniformly and penetratingly arranged on the outer surface of the mixing cylinder 1, and the feeding grooves are inserted into the feeding openings.
[0038] By arranging a plurality of feeding grooves, different types, colors and properties of plastic particles can be simultaneously or batched into the mixing cylinder 1, so as to ensure the uniformity of the mixing of the plastic particles.
[0039] Working principle: When different types, colors and properties of plastic particles enter the mixing cylinder 1 from the feeding assembly 4, the motor 2 is operated to drive the spiral conveyor 301 and the annular support plate 6 to rotate, and the broken blades 303 and the stirring paddles 305 to rotate around the inner wall of the mixing cylinder 1. When the broken blades 303 rotate, the driven gear 501 is driven to rotate at the same time.
