DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 、 Figure 3 、 Figure 4The utility model provides an embodiment of a plastic recycling mixing device, including a mixing barrel 1, a conveying mechanism is provided inside the mixing barrel 1, and the conveying mechanism includes a stepping motor 6. The stepping motor 6 can accurately control the rotation angle of its output shaft, conveniently adjust the rotation speed and rotation angle of its rotating shaft, and can be adjusted accordingly according to different working requirements to improve the control accuracy. The stepping motor 6 is fixedly installed on the top of the mixing barrel 1, and the bottom of the output shaft of the stepping motor 6 is fixedly connected to a roller 7 arranged in a vertical state. The circumferential surface of the roller 7 is fixedly connected with a spiral conveying blade 8. The surface of the spiral conveying blade 8 is fixedly connected with a tumbling ball 9 for bumping and rolling the recycled plastic particles. When the recycled plastic particles collide with the tumbling ball 9 during the upward displacement, they will roll, which improves the stirring and mixing effect to a certain extent. The outer wall of the spiral conveying blade 8 is fixedly connected with a sleeve 10. The central axis of the roller 7 and the central axis of the sleeve 10 are on the same straight line, which improves the stability of the sleeve 10 driven by the roller 7 to rotate.

[0032] Reference Figure 3 - Figure 5 The interior of the mixing barrel 1 is provided with a disturbance mechanism, which includes a fixed block 11 and a moving rod 13 arranged in a horizontal state. The fixed block 11 is fixedly installed on the circumferential surface of the rotating roller 7, and the fixed block 11 is fixedly connected to an S-shaped fixed plate 12 on the side away from the rotating roller 7. The moving rod 13 passes through and is slidably installed on the inner wall of the sleeve 10, and the sliding direction of the moving rod 13 is the radial direction of the sleeve 10. The moving rod 13 is elastically connected to the fixed plate 12 by a spring piece 14, and the spring piece 14 is arranged in an arc shape. The number of spring pieces 14 is set to multiple, and the multiple spring pieces 14 are symmetrically arranged on the surface of the moving rod 13. Through the symmetrical arrangement of the multiple spring pieces 14, the resultant force applied by the multiple spring pieces 14 is in the radial direction of the sleeve 10. By setting the multiple spring pieces 14, an elastic force away from the fixed block 11 is applied to the moving rod 13. One end of the spring piece 14 is fixedly connected to the end of the fixed plate 12 away from the fixed block 11, and the other end of the spring piece 14 is fixedly connected to the circumferential surface of the moving rod 13.

[0033] Reference Figure 3 - Figure 5, the end of the moving rod 13 close to the fixed block 11 is fixedly connected to a plurality of S-shaped pushing plates 15, which can better fit the extension direction of the spiral conveying blade 8 and achieve a better pushing effect. The end of the moving rod 13 away from the fixed block 11 is fixedly connected to the extrusion block 16, and the inner wall of the mixing barrel 1 is fixedly connected to a protrusion 17 that cooperates with the extrusion block 16. The protrusion 17 is arranged in a vertical state, and the side of the extrusion block 16 away from the moving rod 13 is provided with an arc surface, and the side of the protrusion 17 away from the inner wall of the mixing barrel 1 is provided with an arc surface. The number of protrusions 17 is set to multiple A plurality of protrusions 17 are arranged on the inner wall of the mixing barrel 1 in a ring-shaped and equiangular manner. By setting a plurality of protrusions 17, when the sleeve 10 drives the moving rod 13 to rotate one circle, the displacement of the moving rod 13 will drive the pushing plate 15 to move back and forth multiple times, thereby improving the stirring and mixing effect. Taking into account the fatigue strength of the spring and the effect of pushing and mixing, the number of protrusions 17 is preferably set to four to six. The circumferential surface of the moving rod 13 is fixedly connected to the impact ring 18, which is arranged in an arc shape, which can increase the probability of collision with the plastic recycled particles and improve the stirring and mixing effect.

[0034] Reference Figure 1 - Figure 3 The bottom of the mixing barrel 1 is fixedly connected to a hot air blower 19 that can blow out hot air, which has the effect of heating, drying and reducing the moisture content of the recycled plastic particles. It is a prior art. An air outlet 20 is provided on the top of the hot air blower 19. The hot air blown out by the hot air blower 19 is blown from the bottom of the mixing barrel 1 to the top of the mixing barrel 1, which is opposite to the direction in which the recycled plastic particles fall, thereby increasing the contact time between the hot air and the recycled plastic particles and improving the heating and drying effect. The air outlet 20 is arranged inside the mixing barrel 1, and an exhaust hole 21 is provided on the top of the mixing barrel 1. The hot air containing water vapor is discharged from the exhaust hole 21.

[0035] Reference Figure 1 、 Figure 2 The circumferential surface of the mixing barrel 1 is fixedly connected with a plurality of support legs 2 which serve as fixed supports to ensure the overall stability of the equipment when working. The bottom of the support legs 2 is fixedly connected with a bottom plate 3 arranged in a horizontal state. A material receiving box 4 is provided on the top of the bottom plate 3. The material receiving box 4 can be taken from the top of the bottom plate 3 to facilitate the transfer of the plastic recycled particles that have been stirred and dried to the next process. A feeding pipe 5 for feeding plastic recycled particles into the mixing barrel 1 is fixedly connected to the top of the mixing barrel 1. A solenoid valve 22 is fixedly connected to the bottom of the mixing barrel 1. The solenoid valve 22 is initially in a closed state. When the solenoid valve 22 is opened, the plastic recycled particles inside the mixing barrel 1 can be discharged into the material receiving box 4.

[0036] Working principle: When in use, the cleaned recycled plastic particles are fed into the mixing barrel 1 through the feeding pipe 5, and then the stepper motor 6 is started. The stepper motor 6 works to rotate the roller 7, and the rotation of the roller 7 drives the spiral conveying blade 8 to rotate. The rotation of the spiral conveying blade 8 causes the plastic recycled particles inside the mixing barrel 1 to be transported from the bottom of the mixing barrel 1 to the top of the mixing barrel 1, and then fly and scatter back to the bottom of the mixing barrel 1 in an umbrella shape, realizing up and down rolling and stirring, so that the plastic recycled particles are evenly mixed.

[0037] The rotation of the spiral conveying blade 8 will also drive the sleeve 10 and the moving rod 13 to rotate. The rotation of the moving rod 13 drives the extrusion block 16 to continuously contact multiple protrusions 17. When the extrusion block 16 contacts the protrusion 17, the protrusion 17 squeezes the extrusion block 16, so that the extrusion block 16 overcomes the elastic force of the spring piece 14 and moves in the direction close to the fixed block 11. When the extrusion block 16 and the protrusion 17 are out of contact, the extrusion block 16 is displaced in the direction away from the fixed block 11 under the elastic force of the spring piece 14. As the stepper motor 6 drives the sleeve 10 to rotate continuously, the moving rod 13 will also perform reciprocating linear motion in the radial direction of the sleeve 10. The displacement of the moving rod 13 drives multiple push plates 15 to perform reciprocating linear motion, thereby continuously pushing the plastic recycled particles in the rising process, further improving the stirring and mixing effect, reducing the possibility of the plastic recycled particles sticking together due to moisture, and improving the subsequent heating and drying effect.

[0038] In the process of the spiral conveying blades 8 rotating to drive the recycled plastic particles to rise, the recycled plastic particles will also collide with the tumbling spheres 9, producing a certain tumbling mixing effect. Then, the recycled plastic particles that rise to the top of the mixing barrel 1 fall back into the bottom of the mixing barrel 1 from the top of the sleeve 10 through the sleeve 10 and the inner wall of the mixing barrel 1. In this process, they will collide with the moving rod 13 and the impact ring 18, thereby breaking up the recycled plastic particles, increasing the contact time between the recycled plastic particles and the hot air blown out by the hot air blower 19, and at the same time improving the stirring, mixing and heating and drying effects. After multiple cycles, the solenoid valve 22 is opened to discharge the stirred and dried recycled plastic particles into the receiving box 4, making it convenient to transfer the recycled plastic particles to the next process.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
