[0002] According to the patent document with authorization announcement number "CN108972933B" and invention title "A stirring device for plastic production," the description states that: multiple corrugated guide grooves are spaced apart on the second impeller, and the direction of the guide grooves is along the axial direction of the second rotating shaft. This design of the guide grooves serves two purposes: firstly, when the raw material flows through the corrugated guide grooves, it can cause a large swirling flow, allowing the slurry to be fully stirred; secondly, because the raw material moves away from the axial direction of the second stirring shaft due to centrifugal force when driven by the second impeller, the guide groove design allows the raw material to move closer to the axial direction of the second rotating shaft, to a certain extent balancing the movement of the raw material away from the second stirring shaft due to centrifugal force, making the raw material more evenly stirred and improving the stirring effect. However, the following drawbacks still exist:

[0003] During mixing, the blades do not easily stir the raw materials at the bottom of the mixing drum, causing the sediment in the finished product to settle to the bottom of the mixing drum, thus affecting the plastic production effect. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a finished product stirring device for plastic production, which effectively solves the problem that the sediment in the raw material finished product easily settles to the bottom of the stirring drum during the stirring process.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Depend on Figure 1-6The present invention relates to a finished product mixing device for plastic production, comprising a mixing drum 1, a feed pipe 2 installed at the top of the mixing drum 1, a discharge pipe 3 installed at the bottom of the mixing drum 1, valves 4 installed on both the feed pipe 2 and the discharge pipe 3, and a pushing and mixing component 5 installed inside the mixing drum 1.

[0027] The mixing drum 1 includes a bottom drum 101, a middle drum 102 at the top of the bottom drum 101, and a top drum 103 at the top of the middle drum 102. The diameter of the top of the middle drum 102 is larger than the diameter of the bottom of the middle drum 102. The diameter of the top of the middle drum 102 is the same as the diameter of the top drum 103, and the diameter of the bottom of the middle drum 102 is the same as the diameter of the bottom drum 101. The outer wall of the push plate 501 is in close contact with the inner wall of the bottom drum 101. A rotating screw 104 is coaxially rotatably installed inside the mixing drum 1. The top of the rotating screw 104 is fixedly connected to the output shaft of the drive motor 105. The drive motor 105 is fixedly installed at the top of the mixing drum 1. The rotating screw 104 is threadedly connected to the middle screw groove 502. A fixing screw 106 is installed at equal angles inside the mixing drum 1. The fixing screw 106 is located inside the guide groove 504.

[0028] The stirring assembly 5 includes a pusher plate 501 movably installed inside the stirring drum 1. The stirring drum 1 consists of a bottom drum 101, a middle drum 102, and a top drum 103. The outer wall of the pusher plate 501 is in close contact with the inner wall of the bottom drum 101. The pusher plate 501 moves upward under the action of the rotating screw 104, thereby pushing the raw material at the bottom of the bottom drum 101 to flow upward, preventing the raw material from settling at the bottom of the bottom drum 101 and improving the stirring effect. A central screw groove 502 is provided in the middle of the pusher plate 501, guide grooves 504 are provided at equal angles on the pusher plate 501, unidirectional flow units 503 are provided at equal angles on the pusher plate 501, and rotating stirring units 505 are provided at equal angles on the pusher plate 501. The rotating stirring unit 505 corresponds one-to-one with the guide groove 504. The unidirectional flow unit 503 includes flow holes 5031 opened at equal angles on the push plate 501. The flow holes 5031 and the guide groove 504 are staggered. A baffle 5032 is set at equal angles on the top of the push plate 501. The diameter of the baffle 5032 is larger than the inner diameter of the flow hole 5031. The baffle 5032 closes the top of the flow hole 5031. A connecting rod 5035 is installed at equal angles on the bottom of the baffle 5032. A movable block 5034 is installed at the bottom of the connecting rod 5035. The movable block 5034 is movably installed inside the movable groove 5033. The movable groove 5033 is opened inside the push plate 501 and is set at equal angles to the flow hole 503. On the outside of 1, a spring 5036 is installed at the top of the movable block 5034. The top of the spring 5036 is fixedly connected to the inner top wall of the movable groove 5033. The bottom wall of the baffle 5032 contacts the top wall of the push plate 501. When the push plate 501 moves upward, the baffle 5032 and the push plate 501 push the raw material product upward. When the push plate 501 moves downward, the bottom wall of the baffle 5032 generates pressure, causing the push plate 501 and the baffle 5032 to open, facilitating the push plate 501 to move back to the bottom of the bottom cylinder 101 for subsequent stirring. The rotating stirring unit 505 includes a rotating block 5051 set above the guide groove 504. Fan blades 5052 are installed at equal angles on the outside of the rotating block 5051. The interior of 51 has a connecting screw groove 5053. The rotating block 5051 is threadedly connected to the fixed screw 106 through the connecting screw groove 5053. A limiting ring 5054 is installed at the bottom end of the rotating block 5051. The limiting ring 5054 is rotatably installed inside the limiting ring groove 5055. The limiting ring groove 5055 is opened inside the push plate 501. The push plate 501 is slidably connected to the fixed screw 106 through the guide groove 504. The top of the push plate 501 is rotatably installed with the rotating block 5051 at an equal angle. The rotating block 5051 is threadedly connected to the fixed screw 106 through the connecting screw groove 5053. When the push plate 501 moves longitudinally back and forth, it drives the rotating block 5051 to rotate, so that the fan blade 5052 rotates to stir the raw materials and finished products.

[0029] Working principle: During operation, first open valve 4 on feed pipe 2 to introduce the raw material to be stirred into the mixing drum 1. Then close valve 4 on feed pipe 2. When the raw material is inside the mixing drum 1, the raw material may settle at the bottom of the mixing drum 1.

[0030] Then, the drive motor 105 is turned on, causing the rotating screw 104 to rotate. Since the rotating screw 104 is threadedly connected to the push plate 501, and the push plate 501 is guided by the fixed screws 106, the push plate 501 moves upward. After the rotating screw 104 rotates in the opposite direction, it drives the rotating screw 104 to move downward, causing the push plate 501 to move longitudinally back and forth inside the mixing drum 1. Since the mixing drum 1 is composed of three parts: the bottom drum 101, the middle drum 102, and the top drum 103, when the push plate 501 moves upward inside the bottom drum 101, it pushes the raw material product at the bottom to flow upward. When the push plate 501 enters the middle drum 102, the raw material product flows back from between the push plate 501 and the middle drum 102 to the bottom drum 101, so that the raw material product inside the mixing drum 1 circulates up and down, thereby avoiding the sedimentation of the raw material product at the bottom.

[0031] During the upward movement of the push plate 501, the baffle 5032 closes the top of the flow hole 5031, which facilitates the upward movement of the raw material product at the bottom. When the baffle 5032 moves downward, the raw material product exerts pressure on the bottom of the baffle 5032, causing the baffle 5032 to move upward relative to the push plate 501. This allows the raw material product to flow through the gap between the push plate 501 and the baffle 5032 to the top of the push plate 501, which facilitates the longitudinal reciprocating movement of the push plate 501 inside the mixing drum 1.

[0032] A rotating block 5051 is rotatably mounted on the top of the push plate 501. The rotating block 5051 is threadedly connected to the fixed screw 106 through the connecting screw groove 5053. When the push plate 501 moves longitudinally back and forth, the rotating block 5051 rotates continuously, causing the fan blade 5052 to stir the raw materials and finished products, which facilitates the stirring of the raw materials and finished products.
