[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This embodiment provides a technical solution: a polyethylene granule modified mixing and regulating mixer, including a mixing drum 1 and a mixing mechanism 3;

[0024] Mixing drum 1: It includes a slewing bearing 2 fixedly connected to the upper side inside, a controller 11 on the outside of the mixing drum 1, the input end of the controller 11 is electrically connected to an external power source, a feed hopper 6 is provided on the upper right side of the outer arc surface of the mixing drum 1, a discharge pipe 7 is provided on the lower right side of the outer arc surface of the mixing drum 1, a valve 8 is connected in series in the middle of the discharge pipe 7, the input end of the valve 8 is electrically connected to the output end of the controller 11, a support 9 is provided on the outside of the mixing drum 1, and a viewing window 10 is provided on the upper front side of the outer arc surface of the mixing drum 1. When it is necessary to use this mixing and adjusting mixer, the proportioned polyethylene granule raw material and modified material can be discharged into the interior of the mixing drum 1 through the feed hopper 6 by the lifting of the elevator.

[0025] Mixing and stirring mechanism 3: It includes a partition plate 31, an internal stirring frame 32, a stirring main shaft 33, a main stirring spiral blade 34, an auxiliary stirring shaft 35, an auxiliary stirring spiral blade 36, and a bottom bearing seat 39. The partition plate 31 is fixedly connected to the inner ring surface of the slewing bearing 2. The stirring main shaft 33 is fixedly connected to the middle of the lower surface of the partition plate 31. The bottom bearing seat 39 is provided in the middle of the lower side wall of the stirring cylinder 1. The inner ring surface of the bearing of the bottom bearing seat 39 is fixedly connected to the lower side of the outer arc surface of the stirring main shaft 33. The main stirring spiral blade 34 is fixedly connected to the outer arc surface of the stirring main shaft 33. The internal stirring frame 32 is fixedly connected to the lower surface of the partition plate 31. The auxiliary stirring shaft 35 is symmetrically rotatably connected between the lower inclined wall of the internal stirring frame 32 and the lower surface of the internal stirring frame 32. Auxiliary stirring spiral blades 36 are fixedly connected to the outer arc surface of the mixing shaft 35. The lower side of the internal stirring frame 32 is fixedly connected to the lower side of the outer arc surface of the stirring main shaft 33. The mixing mechanism 3 also includes gears 37 and gear rings 38. Gears 37 are fixedly connected to the upper ends of the two auxiliary stirring shafts 35. A gear ring 38 is provided on the upper side of the inner arc surface of the mixing cylinder 1. Two gears 37 are meshed with one gear ring 38. A cover 4 is fixedly connected to the upper side of the mixing cylinder 1. A motor 5 is fixedly connected to the upper surface of the mixing cylinder 1. The output shaft of the motor 5 is fixedly connected to the middle of the upper surface of the partition 31. The input end of the motor 5 is electrically connected to the output end of the controller 11. Then, the controller 11 can be controlled to operate the motor 5. The output shaft of the motor 5 rotates, thereby driving the partition 31 to rotate. Then, the main stirring spiral blades 34 are driven to rotate by the stirring main shaft 33. During the rotation of the partition plate 31, the two auxiliary stirring shafts 35 rotate around the central axis of the stirring main shaft 33. At the same time, the two gears 37 and a gear ring 38 maintain a meshing connection in real time. When the two auxiliary stirring shafts 35 revolve around the central axis of the stirring main shaft 33, they will also rotate on their own axis. At this time, the proportioned polyethylene granule raw materials and modified materials can be continuously discharged into the interior of the stirring drum 1. At this time, the material inside the stirring drum 1 can be observed through the viewing window 10. When the material reaches the specified quantity, the feeding can be stopped. The main stirring spiral blades 34 on the stirring main shaft 33 rotate upward, while the auxiliary stirring spiral blades 36 on the auxiliary stirring shafts 35 rotate downward. As the material moves downwards, the bottom material is tumbled upwards along the rotating main stirring spiral 34. The rotation of the main stirring shaft 33 also drives the internal stirring frame 32 to rotate. Simultaneously, the outer surface of the internal stirring frame 32 adheres to the inner arc surface of the mixing drum 1. Notably, during the rotation of the internal stirring frame 32, the auxiliary stirring spiral 36 also rotates, stirring the surrounding material. This reduces the rotational resistance of the internal stirring frame 32. As the bottom material tumbles upwards, the auxiliary stirring spiral 36 on the auxiliary stirring shaft 35 continuously disperses the upward-tumbling material, which then settles to the bottom and is again tumbled upwards by the main stirring spiral 34, completing the thorough mixing of the polyethylene granule raw material and the modified material.This mixing process lasts for 15 minutes. After mixing is complete, the controller 11 can be adjusted, the output shaft of the motor 5 will rotate in the reverse direction, and the valve 8 will open. At this time, the main mixing spiral blade 34 guides the material downwards, and the auxiliary mixing spiral blade 36 pours the material upwards. This material will be discharged from the mixer through the discharge pipe 7. The discharged material is the polyethylene granules that have undergone modified mixing.

[0026] The working principle of the polyethylene granule modified mixing and regulating mixer provided by this utility model is as follows: When the mixing and regulating mixer is needed, the proportioned polyethylene granule raw material and modified material can be discharged into the mixing drum 1 through the feed hopper 6 by the elevator. Then, the controller 11 can be controlled to start the motor 5. The output shaft of the motor 5 rotates, thereby driving the partition 31 to rotate. This, in turn, drives the main stirring spiral blade 34 to rotate through the stirring main shaft 33. During the rotation of the partition 31, the two auxiliary stirring shafts 35 rotate around the central axis of the stirring main shaft 33. At the same time, the two gears 37 and a gear ring 38 maintain a meshing connection in real time. When the two auxiliary stirring shafts 35 revolve around the central axis of the stirring main shaft 33, they will also rotate on their own axis. At this time, the proportioned polyethylene granule raw material and modified material can be continuously discharged into the mixing drum 1. At this time, the viewing window 10 can be observed to judge the situation. When the material inside the mixing drum 1 reaches the specified quantity, feeding can be stopped. The main stirring spiral blade 34 on the main stirring shaft 33 rotates upward, while the auxiliary stirring spiral blade 36 on the auxiliary stirring shaft 35 rotates downward. At this time, the material at the bottom will be turned upward along the rotating main stirring spiral blade 34. During the upward turning of the material at the bottom, the auxiliary stirring spiral blade 36 on the auxiliary stirring shaft 35 continuously disperses the upward turning material, and then sinks to the bottom to be turned upward again by the main stirring spiral blade 34, thus completing the thorough mixing of polyethylene granule raw material and modified material. This mixing lasts for 15 minutes. After the mixing is completed, the controller 11 can be adjusted, the output shaft of the motor 5 rotates in the reverse direction, and the valve 8 opens. At this time, the main stirring spiral blade 34 guides the material downward, and the auxiliary stirring spiral blade 36 pours the material upward. This material will be discharged from the outside of the mixer through the discharge pipe 7. The discharged material is the polyethylene granules that have completed the modified mixing.

[0027] It is worth noting that the core chip of the controller 11 disclosed in the above embodiments is a microcontroller, specifically an STM32. The motor 5 and valve 8 can be freely configured according to the actual application scenario. It is recommended to use a TFO-KK5.5KW motor for motor 5 and a VT powder granule butterfly valve for valve 8. The controller 11 controls the operation of motor 5 and valve 8 using methods commonly used in the prior art.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
