DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The technical solutions of this patent will be further described in detail below in conjunction with the specific embodiments:

[0025] Embodiment 1

[0026] Please refer to Figures 1-7, A mixing and stirring device for resin, including a support frame 1, a stirring barrel 9 is installed on the support frame 1, a gearbox 3 is installed on the stirring barrel 9, a cantilever frame 4 is fixed on the gearbox 3, a threaded rod 10 is rotatably installed on the cantilever frame 4, and a driving component for driving the threaded rod 10 to rotate clockwise and counterclockwise alternately is provided inside the gearbox 3. The inside of the provided stirring barrel 9 is used to store the raw materials used in the resin processing process, that is, the raw materials are placed in the stirring barrel 9 for subsequent stirring and mixing.

[0027] A threaded sleeve block 5 that slides relative to the cantilever frame 4 is threadedly sleeved on the threaded rod 10. The threaded sleeve block 5 is installed with a guide sleeve block 6 through a connecting component. An extension plate 7 is passed through the guide sleeve block 6. A fixed sleeve block 11 is fixed on the gearbox 3. One end of the extension plate 7 away from the guide sleeve block 6 is installed on the fixed sleeve block 11. A protective cover 8 is fixed on the guide sleeve block 6, and a stirring component located inside the stirring barrel 9 is rotatably installed on the protective cover 8.

[0028] The raw materials in the stirring barrel 9 are rotated and stirred by the provided stirring component to achieve the purpose of mixing the raw materials used in resin processing. With the help of the driving component, the position of the stirring component can be linearly moved to expand the stirring and mixing range.

[0029] Specifically, the driving component includes a driven bevel gear I 28 and a driven bevel gear II 29 that are coaxially connected to the threaded rod 10. An incomplete bevel gear 30 is rotatably installed inside the gearbox 3. The incomplete bevel gear 30 is alternately meshed with the driven bevel gear I 28 and the driven bevel gear II 29. A servo motor 2 for driving the incomplete bevel gear 30 to rotate is installed outside the gearbox 3.

[0030] Based on the above settings, when the servo motor 2 is started, the output shaft of the servo motor 2 drives the incomplete bevel gear 30 to rotate. The incomplete bevel gear 30 is alternately meshed with the driven bevel gear I 28 and the driven bevel gear II 29, and the rotation directions of the driven bevel gear I 28 and the driven bevel gear II 29 are always opposite, that is, the threaded rod 10 rotates clockwise and counterclockwise alternately. The threaded rod 10 drives the threaded sleeve block 5 to move reciprocally along the axis direction of the threaded rod 10. At this time, the threaded sleeve block 5 drives the guide sleeve block 6 to slide relative to the extension plate 7 through the connecting component, that is, the stirring component is reciprocally linearly moved relative to the extension plate 7, realizing the comprehensive stirring effect on the raw materials in the stirring barrel 9 and promoting the full mixing of the raw materials.

[0031] In addition, a limiting block 23 is fixed on the threaded sleeve block 5. The limiting block 23 is slidably embedded on the cantilever frame 4. A limiting rod 24 is fixed on the cantilever frame 4. The limiting block 23 is slidably sleeved on the limiting rod 24. When the threaded sleeve block 5 moves relative to the threaded rod 10, the limiting block 23 slides relative to the cantilever frame 4 under the guiding action of the limiting rod 24, thus realizing the guiding and limiting effects on the threaded sleeve block 5 and ensuring the stable movement of the threaded sleeve block 5.

[0032] Among them, the above-mentioned connecting component includes a mounting seat 32 fixed to the threaded sleeve block 5. A sleeve 13 is fixed on the mounting seat 32. A sliding column 22 is slidably mounted on the sleeve 13. A connecting spring 27 is installed between the sliding column 22 and the sleeve 13. One end of the sliding column 22 away from the sleeve 13 is hinged to the guiding sleeve block 6.

[0033] During the process of the threaded sleeve block 5 sliding relative to the threaded rod 10, the distance between the threaded sleeve block 5 and the extension plate 7 changes, enabling the sliding column 22 to slide relative to the sleeve 13. At this time, the connecting spring 27 undergoes elastic deformation to ensure that the threaded sleeve block 5 drives the guiding sleeve block 6 smoothly through the connecting component.

[0034] In addition, a cylinder 12 is fixed on the gearbox 3. The telescopic end of the cylinder 12 is hinged to the extension plate 7. The extension plate 7 is hinged to the fixed sleeve block 11. The cylinder 12 can drive the extension plate 7 to deflect relative to the fixed sleeve block 11, enabling the position angle of the stirring component in the stirring barrel 9 to be adjusted, that is, it can be adjusted to different position states to achieve full mixing of the raw materials in the stirring barrel 9, and the full mixing of the raw materials can be significantly improved.

[0035] Embodiment 2

[0036] Please refer to Figures 1-7 , on the basis of Embodiment 1, in addition, the stirring component includes a driving shaft 25 rotatably mounted on the guiding sleeve block 6. A moving gear 17 is coaxially fixed on the driving shaft 25. A rack 26 meshing with the moving gear 17 is fixed on the extension plate 7. A rotating frame 19 is fixed on the driving shaft 25. A plurality of driven shafts 20 are rotatably mounted on the rotating frame 19. A plurality of stirring frames 21 are fixed on each driven shaft 20.

[0037] As Figures 4-5 shown, during the process of the guiding sleeve block 6 linearly moving relative to the extension plate 7, the driving shaft 25 moves along with the guiding sleeve block 6. The moving gear 17 on the driving shaft 25 is meshed with the rack 26 to achieve the rotating effect of the driven shaft 20. The driving shaft 25 drives the rotating frame 19 to rotate, and further realizes the relative rotation of the driven shaft 20 and the stirring frame 21 around the center of the driving shaft 25 to achieve the stirring and mixing of the raw materials.

[0038] Furthermore, the stirring component further includes a transmission gear 18. The transmission gear 18 is coaxially connected to the driven shaft 20. An internal gear ring 31 meshing with the transmission gear 18 is fixed on the inner wall of the protective cover 8.

[0039] When the rotating frame 19 rotates, the transmission gear 18 on the driven shaft 20 rotates relative to the driving shaft 25. The transmission gear 18 is meshed and connected with the internal gear ring 31 to achieve rotation. At this time, the driven shaft 20 rotates self and drives the stirring frame 21 to rotate, thus realizing the stirring effect of the raw materials in the stirring barrel 9, and the raw materials are mixed fully and efficiently.

[0040] In addition, the stirring barrel 9 is rotatably installed on the support frame 1. A driving motor 14 is installed on the support frame 1. The output shaft of the driving motor 14 is drivingly connected with a worm 15. The stirring barrel 9 is coaxially connected with a worm gear 16. The worm gear 16 is in transmission connection with the worm 15.

[0041] Start the set driving motor 14. The driving motor 14 drives the worm 15 to rotate. The worm 15 drives the worm 15 to rotate. The worm 15 drives the stirring barrel 9 to rotate, and then drives the raw materials to rotate. Combined with the rotation of the stirring assembly, the stirring degree of the raw materials is greatly improved, and the raw material mixing process is sufficient and fast.

[0042] In summary, the present invention realizes the stirring and mixing of the raw materials inside the stirring barrel 9 through the rotation of the set stirring assembly. During this process, the guiding sleeve block 6 performs a linear reciprocating motion relative to the extension plate 7, which not only realizes the driving effect on the stirring assembly, but also can realize the continuous movement and change of the stirring and mixing position of the stirring assembly, greatly improving the degree of full mixing of the raw materials. The extension plate 7 in the present invention can be deflected and adjusted relative to the fixed sleeve block 11 under the driving action of the cylinder 12, realizing the adjustment effect of the inclination degree of the stirring assembly connected to the guiding sleeve block 6, so that the stirring assembly can fully and comprehensively mix and process the raw materials in the stirring barrel 9 from different moving directions. The stirring frame 21 in the stirring assembly of the present invention can not only rotate around the center of the driven shaft 20, but also rotate around the center of the driving shaft 25, and the above-mentioned rotation direction of the stirring frame 21 can change periodically, so that the raw materials used in the resin production and processing process can be repeatedly stirred, greatly improving the mixing degree of the raw material components.
