By opening the discharging module, the adjusting unit and the mixing and stirring unit work together to adjust the angle, distance and height of the two stirring rods, so that the stirring rod has a wider range of motion, which is beneficial to the all-round mixing of different types of magnetic particles in the first bucket. This saves time and improves the efficiency of the mixing device for mixing magnetic particles. The device can save time and improve the efficiency of the device for quantitative feeding of magnetic particles. It also avoids the error of human quantitative feeding of magnetic particles in the later stage.

[0005] The above-mentioned mechanism can improve the working efficiency of mixing by quantitative feeding, and avoid the weight error caused by manual operation. However, in actual use, after quantitative feeding, the material in the mixer may not be mixed uniformly. UTILITY MODEL CONTENTS

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0031] Embodiment one:

[0032] As Figures 1-4 and Figure 5 The technical scheme shown in the figure, in order to solve the problem that the material enters too fast when the mixer body 5 is in the mixing operation of feeding, leading to the problem of feeding port blockage: the modified plastic particle mixer based on pneumatic spiral material lifting, disclose the timing feeding mechanism, including the mixer body 5, the left side of the mixer body 5 is provided with feed hopper 1, and the right side of the feed hopper 1 is provided with guide rod 2, the inside of guide rod 2 is provided with spiral feeder 3, the lower end of the right side of guide rod 2 is provided with discharge port 4, the top end of the mixer body 5 is provided with feed inlet 6, and the bottom end of the discharge port 4 penetrates and extends to the inside of the feed inlet 6, the inside of the mixer body 5 is provided with servo motor 7 through connecting plate, and the output end of the servo motor 7 is provided with rotating rod 8, the outside of rotating rod 8 is provided with stirring rod 9, the lower end of feed inlet 6 is provided with timing feeding mechanism for controlling feeding time, the timing feeding mechanism includes baffle 13, and the baffle 13 is arranged below the feed inlet 6, the baffle 13 is rotatably connected to the inside of the mixer body 5 through connecting rod 15, the upper end of the output end of the servo motor 7 is provided with inclined disc 14, the outside of connecting rod 15 is wound with torsional spring, and the baffle 13 and connecting rod 15 constitute elastic structure through torsional spring, the thickness of the left and right sides of inclined disc 14 is different, and the inclined disc 14 is arranged below the baffle 13.

[0033] In this case, the motor drives the screw feeder 3 inside the material guide rod 2 to rotate, so that the screw feeder 3 can lift the plastic particles inside the feeding hopper 1 to the feeding port 6, and the plastic particles enter the inside of the mixer body 5 through the feeding port 6. The output end of the servo motor 7 drives the rotating rod 8 to rotate, and the rotating rod 8 can drive the stirring rod 9 to mix the plastic particles inside;

[0034] In order to ensure the stability of the plastic particles during mixing, the output end of the servo motor 7 can drive the inclined disc 14 to rotate, and the inclined disc 14 can push the baffle 13 at the top during continuous rotation, so that the angle of the baffle 13 is deflected. After the deflection of the baffle 13, the feeding port 6 is not shielded, so that the material temporarily stored in the feeding port 6 falls into the inside of the mixer body 5 for stirring and mixing treatment, and the time for storing material and the time for not shielding the feeding port 6 are fixed each time, so that the amount of material added each time is fixed and limited, which is convenient for better adjusting the amount of material added according to different needs, and increases the flexibility during use.

[0035] Example two:

[0036] As shown in Figures 1-4 and Figures 5-6 In order to solve the problem that the material at the corners of the mixer body 5 cannot be contacted by the rotating rod 8 and the stirring rod 9, resulting in insufficient mixing degree: the modified plastic particle mixer based on pneumatic screw lifting discloses an auxiliary mixing mechanism, the inside of the mixer body 5 is provided with a mounting bracket 16, and the auxiliary mixing mechanism for stirring the corners is arranged between the mounting brackets 16. The auxiliary mixing mechanism includes a rotating rod 17, one end of which is rotatably connected between the mounting brackets 16. The left side of the rotating rod 17 is provided with two stirring pieces 18, the right side of the stirring rod 9 is in close contact with the left side of the stirring piece 18, and the stirring pieces 18 are evenly distributed in the inside of the mixer body 5. The outside of the rotating rod 17 is wound with a torsion spring, and the stirring piece 18 and the mounting bracket 16 form an elastic structure through the torsion spring.

[0037] In this case, the servo motor 7 drives the rotating rod 8 and the stirring rod 9 to rotate in the inside of the mixer body 5, and the stirring rod 9 continuously stirs the stirring pieces 18 during rotation, which increases the mixing efficiency;

[0038] At the same time, since the stirring piece 18 and the rotating rod 17 are provided with a torsion spring, the stirring piece 18 will automatically reset after being stirred, so as to assist in mixing the plastic particles at the corners, effectively increasing the working efficiency during deep mixing.

[0039] Example three:

[0040] As Figure 2 and Figure 5 The technical scheme shown in the application, in order to solve the problem that the plastic particles need to be melted and processed after mixing, the temperature of the plastic particles is low, and it is not convenient to quickly melt; the modified plastic particle mixer based on the pneumatic spiral material lifting discloses a preheating mechanism, the outer side of the mixer body 5 is provided with a preheating mechanism, the preheating mechanism comprises heating wires 11, the heating wires 11 are wound on the outer side of the mixer body 5, and the outer side of the heating wires 11 is provided with a heat preservation layer 10, and the right side of the top end of the mixer body 5 is provided with an exhaust port 12.

[0041] In this case, part of the plastic particles need to be transported to the production line and melted after mixing, and the temperature of the plastic particles is low in the previous process, and direct melting at this time will increase the melting time and affect the melting efficiency, therefore, in the process of mixing the plastic particles, the heating wires 11 are used to heat the plastic particles, which can reduce the heating time required for melting the plastic particles in the subsequent process, and the heating of the plastic particles in the process of continuous stirring and mixing can make the overall heating more uniform, effectively avoiding the situation that the temperature of part of the plastic particles cannot be raised.
