[0002] Currently, plastic granules are typically produced using a granulation machine. Before granulation, various plastic raw materials need to be mixed and stirred, and then fed into the granulator for granulation. The current production method involves feeding the raw materials into the mixer, and then manually placing the material bucket into the mixer's outlet for loading, before moving it to the next processing step. This production method has a low degree of automation and slow production efficiency. Utility Model Content

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0017] Example

[0018] To address the aforementioned technical problems, this embodiment provides an automatic stirring and loading mixing device, such as... Figure 1As shown, the system includes a mixing tank 10, within which a stirring assembly 20 is installed. A drive assembly 30 is located on one side of the mixing tank 10 to drive the stirring assembly 20. After raw materials are added to the mixing tank 10, they are mixed by the stirring assembly 20. A feeding assembly 40 is connected to the bottom of the mixing tank 10, and a conveyor belt 50 is positioned below the end of the feeding assembly 40. A material container 60 is conveyed on the conveyor belt 50. When mixing is complete and loading is required, the conveyor belt 50 automatically transports the material container 60 to the end of the feeding assembly 40. The feeding assembly 40 then transfers the raw materials from the mixing tank 10 into the material container 60 for loading. The conveyor belt 50 then automatically transports the material container 60 to the next process step. This achieves automatic mixing, loading, and feeding functions, improving automation and thus increasing production efficiency.

[0019] Specifically, such as Figure 2 As shown, the feeding assembly 40 includes a discharge switch 44 connected to the bottom of the mixing tank 10 and a feeding pipe 41 connected to the bottom of the discharge switch 44. A feeding screw 43 is installed inside the feeding pipe 41. A driver 42 is installed on one side of the mixing tank 10 and is connected to the feeding screw 43. For example, the discharge switch 44 can be connected to a connecting block at the bottom of the mixing tank 10, and an intelligent air valve switch is installed in the connecting block. The discharge switch 44 is opened or closed electrically to control whether to discharge materials. The driver 42 can be a motor. The two sides of the feeding screw 43 are rotatably connected to the feeding pipe 41 through bearings. When the discharge switch 44 is opened, the raw material in the mixing tank 10 falls into the feeding pipe 41, and the driver 42 drives the feeding screw 43 to rotate, so that the raw material is delivered to the end of the feeding pipe 41.

[0020] Furthermore, in the above scheme, a discharge port 45 is provided below the end of the feeding pipe 41. The discharge port 45 is located above the conveyor belt 50, and the material bucket 60 is transported to the area below the discharge port 45 by the conveyor belt 50. The driver 42 drives the feeding screw 43 to rotate, so that the raw material falls from the discharge port 45 at the end of the feeding pipe 41 into the material bucket 60. As a preferred embodiment, the driver 42 can be a stepper motor, which can accurately control the rotation of the feeding screw 43. The number of rotations of the stepper motor during each loading is controlled by a program setting, thereby achieving quantitative loading and ensuring that the weight of the raw material in each bucket is within a certain error range.

[0021] Furthermore, several sets of detectors 51 are installed on both sides of the conveyor belt 50 along the conveying path of the material bucket 60. For example, a detector 51 is installed below the discharge port 45 on the conveyor belt 50. The detector 51 can be a positioning sensor. After detecting that the material bucket 60 has reached the designated position, the conveyor belt 50 stops moving, and the discharge switch 44 and the driver 42 are activated. The feeding assembly 40 then begins to convey the raw materials from the mixing box 10 into the material bucket 60. The conveyor belt 50 can extend to the next processing station to convey the material bucket 60 to the next station for feeding and processing. Alternatively, a robot can be used to grab the material bucket 60 for discharge, provided that another set of positioning sensors is installed at the discharge position so that the robot can grab the positioned material bucket 60.

[0022] In some implementations, a height detector can be installed on the side of the feeding pipe 41 located at the discharge port 45. During the loading process, the height of the raw material in the material bucket 60 can be detected by the height detector to achieve quantitative loading and ensure that the weight of the raw material in each material bucket is the same.

[0023] Furthermore, in order to achieve uniform mixing of various raw materials fed into the mixing tank 10, such as... Figure 3 As shown, the mixing assembly 20 includes a rotating shaft 21 passing through the mixing tank 10 and a spiral mixing blade 22 surrounding the outer circumference of the rotating shaft 21. The outer circumference of the rotating shaft 21 is connected to the spiral mixing blade 22 via a connecting rod 23. The drive end of the drive assembly 30 is connected to the rotating shaft 21. The drive assembly 30 can be a motor, which drives the rotating shaft 21 to rotate, and the rotating shaft 21 drives the spiral mixing blade 22 to rotate, thereby the spiral mixing blade 22 thoroughly mixing the raw materials in the mixing tank 10.

[0024] Furthermore, a hinge block 12 is provided on one side of the top of the mixing tank 10, and a cover plate 11 is connected to the hinge block 12. The cover plate 11 covers the top of the mixing tank 10, so that after the raw materials are put into the mixing tank 10, the cover plate 11 covers the mixing tank 10 to prevent the raw materials from splashing during the mixing process. On the other side of the top of the mixing tank 10, a clamping block 15 is provided on the top of the hinge block 12, so that after the cover plate 11 is covered on the top of the mixing tank 10, the clamping block 15 fixes the cover plate 11.

[0025] Alternatively, in some other implementations, the cover plate 11 is equipped with several feed inlets 14, which are then connected to a suction machine via pipes. The suction machine then transports the raw materials to the mixing box 10 for mixing, thereby improving the level of automation.

[0026] In summary, the present application's solution incorporates a stirring assembly within a mixing tank, and a drive assembly on one side of the mixing tank to drive the stirring assembly. After raw materials are added to the mixing tank, they are mixed by the stirring assembly. A feeding assembly is connected to the bottom of the mixing tank, and a conveyor belt is positioned below the end of the feeding assembly. A material bucket is transported on the conveyor belt. When mixing is complete and loading is required, the conveyor belt automatically transports the material bucket to the end of the feeding assembly, which then transfers the raw materials from the mixing tank 10 into the feeding bucket for loading. The conveyor belt then automatically transports the bucket to the next process. This achieves automatic mixing, loading, and feeding functions, improving automation and thus increasing production efficiency.

[0027] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
