Detailed Description of the Preferred Embodiment
[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0027] In the embodiment, given by Figures 1-4 a mixing and stirring device for plastic particle processing, the present utility model includes a support frame 1, a mixing frame 2 is fixedly connected inside the support frame 1, an extension plate 3 is arranged inside the mixing frame 2, mixing devices 4 are arranged inside both the extension plate 3 and the mixing frame 2, a protective box 5 is fixedly connected to the top of the support frame 1, a reciprocating device 6 is arranged inside the protective box 5, a rack 7 is fixedly connected to the outside of the reciprocating device 6, a connecting shaft 8 is rotatably connected inside the support frame 1 and extends to the outside of the support frame 1, a gear 9 meshing with the rack 7 is fixedly connected to the outside of the connecting shaft 8, a mounting plate 10 is fixedly connected to the outside of the connecting shaft 8, an electric push rod 11 is fixedly connected to the outside of the mounting plate 10, and a material feeding frame 12 is fixedly connected to the outside of the electric push rod 11.
[0028] Among them, the two stirring devices 4 include first motors 41 respectively fixedly connected to the top of the extension plate 3 and the outer side of the stirring frame 2. Stirring shafts 42 rotatably connected to the inside of the stirring frame 2 are fixedly connected to the outer sides of the output shafts of the two first motors 41, and a plurality of stirring rods 43 are fixedly connected to the outer sides of the two stirring shafts 42.
[0029] In this embodiment, during actual use, the startup of the two first motors will drive the two stirring shafts 42 to rotate, and drive the stirring rods 43 to stir the plastic particles in the stirring frame 2. The two stirring devices 4 are arranged in different directions, making the stirring and mixing more sufficient.
[0030] Among them, a connecting frame 13 is fixedly connected to the inside of the stirring frame 2. The top of the connecting frame 13 is rotatably connected to the upper stirring shaft 42, and the cross-section of the connecting frame 13 is triangular and upward.
[0031] In this embodiment, during actual use, the connecting frame 13 will provide support for the upper stirring shaft 42. When the plastic particles fall, the plastic particles will pass through and slide over the connecting frame 13 without being blocked.
[0032] Among them, the reciprocating device 6 includes a second motor 61 fixedly connected to the outer side of the protective box 5. A reciprocating lead screw 62 rotatably connected to the inside of the protective box 5 is fixedly connected to the outer side of the output shaft of the second motor 61, and a transmission block 63 fixedly connected to the rack 7 is threadedly connected to the outer side of the reciprocating lead screw 62.
[0033] In this embodiment, during actual use, the startup of the second motor 61 will drive the reciprocating lead screw 62 to rotate, and under the action of the thread, the transmission block 63 will drive the rack 7 to move left and right.
[0034] Among them, a bolt knob 14 is threadedly connected to the inside of the material discharging frame 12, and a limiting block 15 is fixedly connected to the bottom of the bolt knob 14.
[0035] In this embodiment, during actual use, when the bolt knob 14 is turned, the limiting block 15 will rise or fall under the action of the thread, and open or close the material discharging hole.
[0036] Among them, a material discharging hole is arranged inside the material discharging frame 12. The maximum cross-sectional area of the limiting block 15 is equal to the inner empty area of the material discharging hole. The top surface of the limiting block 15 is inclined downward, and the side surface of the limiting block 15 is parallel to the side surface of the material discharging frame 12.
[0037] In this embodiment, during the actual use process, when the limiting block 15 descends to a certain extent, the gap between the limiting block 15 and the material discharging frame 12 decreases, and the flow rate of the additive decreases. When the maximum cross-sectional area of the limiting block 15 descends into the material discharging hole, the material discharging hole is blocked, and the additive stops discharging.
[0038] Working principle:
[0039] First, pour the plastic particles into the stirring frame 2, pour the additive into the material discharging frame 12, and adjust the discharging flow rate of the additive through the bolt knob 14. Then start the three motors. The reciprocating movement of the rack 7 will drive the gear 9 to rotate, and then the connecting shaft 8 drives the electric push rod 11 to rotate. While the material discharging frame 12 rotates accordingly, it will also drop the additive downward. And as the electric push rod 11 slowly contracts, the discharging position of the additive slowly decreases within the moving arc area, making the addition of the additive more dispersed, and thus increasing the efficiency of stirring and mixing.
