Description

Technical Field

[0001] This invention belongs to the field of polymer material processing technology, specifically relating to a stirring device for processing thermoplastic polymer materials. Background Technology

[0002] Thermoplastic polymers are widely used in industrial production. They are usually made from resins and additives through a series of processing steps. In the processing, thorough mixing of the raw materials is a crucial step, which usually requires the use of mixing equipment.

[0003] Currently, traditional mixing equipment has a relatively simple structure, mainly consisting of a frame, mixing tank, mixing shaft, motor, and mixing rod. The mixing tank is fixedly mounted on the frame. During operation, the motor starts and drives the mixing shaft to rotate, which in turn drives the mixing rod to rotate, thus achieving the mixing operation of the raw materials inside the tank. However, because the mixing tank is fixed, the flowability of the raw materials within it mainly depends on the rotation of the single mixing rod. The mixing range of a single mixing rod is limited, and some raw materials may receive weak mixing, resulting in poor flowability and ineffective mixing. Therefore, overcoming these technical problems and defects is a key issue that needs to be addressed. Summary of the Invention

In this invention, the mixing tank is fixedly mounted on the frame. When the equipment is running, the motor starts and drives the mixing shaft to rotate, which in turn drives the mixing rod to rotate, thereby realizing the mixing operation of the raw materials in the tank. However, since the mixing tank is fixed, the flowability of the raw materials in the tank mainly depends on the rotation of a single mixing rod. The mixing range of a single mixing rod is limited, and some raw materials may receive weak mixing, resulting in poor flowability of the raw materials in the tank and poor mixing effect. Therefore, this invention provides a mixing device for processing thermoplastic polymer materials.

[0017] The mixing device for processing thermoplastic polymer materials according to the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0019] This embodiment discloses a mixing device for processing thermoplastic polymer materials. Through the ingenious design of the first connecting rod 2, the second connecting rod 3, the drive shaft 5, the drive mechanism 7, and the cam 6, the mixing tank 4 can reciprocate, thereby improving the flowability of the raw materials inside the mixing tank 4 and promoting the mixing of the raw materials. (Refer to...) Figures 1-6 The device mainly includes a frame 1 and a mounting plate 101. The mounting plates 101 are symmetrically fixedly connected to both sides of the upper end of the frame 1. The device is characterized in that: a first connecting rod 2 and a second connecting rod 3 are rotatably mounted on each mounting plate 101. A mixing tank 4 is rotatably connected to one end of each first connecting rod 2 and second connecting rod 3 away from the mounting plate 101. A drive shaft 5 is rotatably mounted in the middle of the frame 1. A drive mechanism 7 that can drive the drive shaft 5 to rotate is mounted on one side of the frame 1. A cam 6 that can squeeze the mixing tank 4 is fixedly mounted on the drive shaft 5. A stirring shaft 8 is rotatably mounted inside the mixing tank 4. A drive assembly 9 that can drive the stirring shaft 8 is mounted on the outer wall of the mixing tank 4. A stirring element 10 is mounted on the stirring shaft 8 inside the mixing tank 4 for stirring the raw materials (the raw materials refer to resins, additives, etc. used for processing thermoplastic polymer materials). Through the coordinated design of the stirring shaft 8, drive assembly 9 and stirring component 10, the raw materials inside the mixing tank 4 can be stirred. Compared with the traditional fixed mixing tank, the movement of the mixing tank 4 increases the fluidity and range of motion of the raw materials during the stirring process, effectively avoiding local accumulation of raw materials or the occurrence of stirring dead corners, and significantly improving the mixing effect of the raw materials.

[0020] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 and Figure 5The drive mechanism 7 includes a drive motor 701, a worm gear 702, and a worm wheel 703. The drive motor 701 is fixedly mounted on the frame 1. The worm gear 702 is fixedly mounted on the output shaft of the drive motor 701. The worm wheel 703, which meshes with the worm gear 702, is fixedly mounted on the drive shaft 5. In actual use, the drive motor 701 is started, which drives the worm gear 702 to rotate. The worm gear 702 meshes with the worm wheel 703, causing the worm wheel 703 to rotate. The worm wheel 703 then drives the drive shaft 5 to rotate.

[0021] In this embodiment, refer to Figure 1 , Figure 2 and Figure 4 The number of cams 6 is several, which can reduce the force borne by each cam 6, reduce the wear and fatigue damage of the cam 6, extend the service life of the cam 6, and improve the reliability and stability of the equipment.

[0022] In this embodiment, refer to Figure 1 , Figure 2 and Figure 5 The drive assembly 9 includes a first motor 901, a driving bevel gear 902, and a driven bevel gear 903. The first motor 901 is fixedly mounted on the mixing tank 4. The output shaft of the first motor 901 is fixedly mounted with the driving bevel gear 902. The driven bevel gear 903, which meshes with the driving bevel gear 902, is fixedly mounted on the mixing shaft 8. In actual use, the first motor 901 is driven, which drives the driving bevel gear 902 to rotate. The driving bevel gear 902 meshes with the driven bevel gear 903, causing the driven bevel gear 903 to rotate. The driven bevel gear 903 drives the mixing shaft 8 to rotate.

[0023] In this embodiment, refer to Figure 5 and Figure 6 The stirring component 10 includes a mounting frame 1001 and a spiral blade 1002. Several mounting frames 1001 are fixedly installed at even intervals on the stirring shaft 8, and several spiral blades 1002 are fixedly installed between the mounting frames 1001. Through the cooperative design of several mounting frames 1001 and spiral blades 1002, not only can the raw material flow along the axial direction of the stirring shaft 8 be generated, but the raw material can also be made to move in the radial and tangential directions. This multi-dimensional stirring action breaks the stratification and local aggregation of the raw material in the stirring tank 4, so that the raw materials can be fully mixed in three-dimensional space.

[0024] In this embodiment, refer to Figure 5 and Figure 6A number of connecting rods 11 are fixedly installed at even intervals on the stirring shaft 8, and a flipping plate 12 is fixedly installed at both ends of each connecting rod 11. Through the cooperative design of the connecting rods 11 and the flipping plate 12, the raw materials can be flipped, thereby improving the mixing effect of the raw materials.

[0025] In this embodiment, refer to Figure 5 and Figure 6 A plurality of mounting cylinders 13 are uniformly spaced and fixedly installed on the stirring shaft 8. Each mounting cylinder 13 has a plurality of fan-shaped blades 14 uniformly spaced and fixedly installed along the circumferential direction. When the fan-shaped blades 14 rotate with the stirring shaft 8, they can generate complex fluid motion. On the one hand, their rotation will push the raw materials to diffuse in all directions; on the other hand, in the tangential direction, the raw materials will generate tangential flow due to the rotation of the fan-shaped blades 14. This multi-dimensional stirring method effectively breaks the stratification and local aggregation of the raw materials in the stirring tank 4, allowing the raw materials to be fully mixed in three-dimensional space.

[0026] In this embodiment, the inner wall of the mixing tank 4 is made of polytetrafluoroethylene (PTFE). PTFE has an extremely low coefficient of friction. When the raw material is stirred in the mixing tank 4, the PTFE inner wall can effectively reduce the friction between the raw material and the mixing tank 4, reduce stirring energy consumption, and improve stirring efficiency. At the same time, the low coefficient of friction can also reduce the adhesion of the raw material to the inner wall of the mixing tank 4, prevent the raw material from accumulating, and ensure the smooth progress of the stirring process.

[0027] The working principle of the mixing device for processing thermoplastic polymer materials according to the present invention is as follows: When needed, the raw material is fed into the mixing tank 4, the drive motor 701 is started, the drive motor 701 drives the worm 702 to rotate, the worm 702 meshes with the worm wheel 703 to make the worm wheel 703 rotate, the worm wheel 703 drives the drive shaft 5 to rotate, the drive shaft 5 drives the cam 6 to rotate, and during the rotation of the cam 6, the mixing tank 4 can be squeezed. Under the action of the first connecting rod 2, the second connecting rod 3 and the partial gravity of the mixing tank 4, the mixing tank 4 can be moved, thereby improving the fluidity of the raw material inside the mixing tank 4; While the mixing tank 4 is moving, the first motor 901 is started. The first motor 901 drives the active bevel gear 902 to rotate. The active bevel gear 902 meshes with the driven bevel gear 903, causing the driven bevel gear 903 to rotate. The driven bevel gear 903 drives the stirring shaft 8 to rotate. The stirring shaft 8 drives the stirring component 10, connecting rod 11, tilting plate 12, mounting cylinder 13 and fan blade 14 to rotate. This allows the raw materials to be stirred from different angles and in different ways, thereby enabling the raw materials to be fully mixed in three-dimensional space and effectively improving the mixing effect of various raw materials in polymer materials.
