[0002] The mixing and stirring device is used for mixing different plastic particles. The mixing and stirring device consists of a stirring barrel, a lid, a motor, a stirrer, a feeding pipe and a valve. When using the mixing and stirring device, workers pour two kinds of plastic particles into the stirring barrel successively, and then start the motor on the lid to make the stirrer start to stir and mix. After stirring and mixing, the valve is opened to make the mixed plastic particles discharge through the discharging pipe.

This solves the problem that when mixing plastic particles, the stirrer is driven by a motor to rotate for mixing. Since the two different plastic particles are poured into the mixing barrel successively, when the stirrer mixes, it is necessary to mix the plastic particles at the bottom with those at the upper layer, which may lead to the problem of taking a long time to mix the plastic particles.

A drive mechanism 24 is arranged at the upper end of the first lid 8. A stirrer 7 is arranged on the inner wall of the mixing barrel 1. The drive mechanism 24 is used to drive the drive shaft 22 and the stirrer 7 to rotate. By setting the mixing assembly 2, when mixing plastic particles, the two plastic particles are respectively poured into the two feed hoppers 21, and then through the drive mechanism 24, the drive shaft 22 is rotated, so that the blades 23 rotate, thereby pouring the plastic particles in the feed hopper 21 into the mixing barrel 1 in piles. Then the stirrer 7 rotates, so as to mix the two piles of plastic particles that enter, and further achieve the effect of quickly mixing the plastic particles as much as possible. The drive mechanism 24 includes an operation box 241 fixedly connected to the upper end of the first lid 8. A first motor 244 is installed at the upper end of the operation box 241. The output end of the first motor 244 is fixed to the stirrer 7. Starting the first motor 244 drives the stirrer 7 to rotate. The arc surface of the stirrer 7 is fixedly connected with a second bevel gear 243. The two sides of the second bevel gear 243 are meshed and connected with a first bevel gear 242. When the stirrer 7 rotates, it drives the second bevel gear 243 to rotate. The drive shaft 22 is fixed to the first bevel gear 242. The drive shaft 22 is rotatably connected to the operation box 241. When the second bevel gear 243 rotates, it drives the first bevel gear 242 to rotate, so as to drive the drive shaft 22 to rotate.

[0030] Referring to Figure 3 As shown, in this embodiment: The sampling assembly 3 includes a discharge chute 31 opened inside the mixing barrel 1. A short blanking pipe 34 is fixedly connected to the lower end of the mixing barrel 1. The short blanking pipe 34 is communicated with the discharge chute 31. When it is necessary to sample the plastic particles after mixing, through the feeding mechanism, the plastic particles enter the discharge chute 31 and then are discharged from the short blanking pipe 34. Workers can catch the discharged plastic particles with a sampling cylinder. Workers can discard the plastic particles that come out first, so as to improve the accuracy of sampling plastic particles. A auger 32 is arranged on the inner wall of the discharge chute 31. When the auger 32 rotates, the plastic particles are driven. A second motor 33 is installed at the right end of the mixing barrel 1. The output end of the second motor 33 is fixed to the auger 32. Starting the second motor 33 drives the auger 32 to rotate. The arc surface of the short blanking pipe 34 is threadedly connected with a second lid 35. Opening the second lid 35 allows the short blanking pipe 34 to discharge.

[0031] Working principle:

[0032] When using the mixing and stirring device, workers pour two kinds of plastic particles into the stirring barrel 1 successively, and then start the motor 244 on the lid, so that the stirrer 7 starts to stir and mix. After stirring and mixing, the valve 6 is opened, so that the mixed plastic particles are discharged through the discharge pipe. When stirring and mixing the plastic particles, the two plastic particles are respectively poured into two feed hoppers 21, and then through the driving mechanism 24, the driving shaft 22 is rotated, so that the blades 23 are rotated, so as to pour the plastic particles in the feed hopper 21 into the stirring barrel 1 in piles. Then the stirrer 7 rotates, so as to mix the two piles of plastic particles entering, and further achieve the effect of quickly mixing the plastic particles as much as possible. The motor 244 is started to drive the stirrer 7 to rotate. The rotation of the stirrer 7 drives the second bevel gear 243 to rotate. The rotation of the second bevel gear 243 drives the first bevel gear 242 to rotate, so as to drive the driving shaft 22 to rotate. When it is necessary to take a sample after mixing the plastic particles, the motor 33 is started to drive the auger 32 to rotate. The rotation of the auger 32 drives the plastic particles, so that the plastic particles enter the discharge chute 31 and then are discharged through the short discharge pipe 34. Workers can catch the discharged plastic particles through the sampling cylinder. Workers can discard the plastic particles that come out first, so as to improve the accuracy of the sampled plastic particles. The lid 35 is opened to make the short discharge pipe 34 discharge.
