Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a raw material mixer for engineering plastic synthesis, comprising two support rods 1, with hydraulic cylinders 9 passing through and fixedly connected to the two support rods 1. Connecting rods 8 are fixedly connected to the telescopic ends of the two hydraulic cylinders 9. Mounting seats 6 are fixedly connected to the lower ends of the two connecting rods 8. A motor 10 passes through and is fixedly connected to one of the connecting rods 8. A first gear 11 is fixedly connected to the output end of the motor 10. Inner and outer gear rings 12 are rotatably connected within the mounting seat 6. The inner and outer gear rings 12 mesh with the first gear 11, and the inner and outer gear rings 12 are connected by teeth. Five second gears 17 are rotatably connected, and the five second gears 17 mesh with the inner and outer gear rings 12. The lower ends of the five second gears 17 are all connected to stirring rods 13, and the lower ends of the five stirring rods 13 are all connected to stirring paddles 15. Each of the five stirring paddles 15 is equipped with a heating element. This design solves the problem in the original device where the engineering plastic mixer causes uneven heating of the plastic raw material in the center of the mixing tank 3 during the mixing process, resulting in clumping. This requires multiple operations, which affects the synthesis effect and processing efficiency of the plastic raw material.

[0022] As the first embodiment of this utility model: a protective cover 5 is fixedly connected to the upper end of the mounting base 6, and a limiting ring 18 is fixedly connected to the upper end of the inner and outer gear rings 12. The limiting ring 18 is rotatably connected inside the protective cover 5. The protective cover 5 installed on the mounting base 6 can protect the inner and outer gear rings 12 and the second gear 17, preventing external dust from entering the mounting base 6. The limiting ring 18 installed on the inner and outer gear rings 12, through mutual cooperation with the protective cover 5, can enable the inner and outer gear rings 12 to rotate stably inside the mounting base 6, thereby supporting the stirring rod 13 to rotate inside the inner and outer gear rings 12. The lower ends of the two support rods 1 are fixedly connected to a fixed platform 2. A protective pad 16 is fixedly connected to the groove at the upper end of the fixed platform 2. A mixing tank 3 is placed inside the protective pad 16. The protective pad 16 installed in the groove of the fixed platform 2 can protect the groove on the surface of the fixed platform 2. When the mixing tank 3 is placed in the fixed platform 2, it can reduce the collision with the groove and prevent the mixing tank 3 and the fixed platform 2 from deforming. By placing the mixing tank 3 in the groove on the surface of the fixed platform 2, the user can export the plastic material in the fixed platform 2 and easily clean the plastic material in the mixing tank 3. A support base 7 is fixedly connected to the circumferential surface of one of the connecting rods 8. A rotating ring 14 is fixedly connected to the circumferential surface of each of the five mixing rods 13. The five rotating rings 14 are rotatably connected to the support base 7. The support base 7 installed on the surface of the connecting rod 8 can help the connecting rod 8 support the mixing paddle 15. When the mixing rod 13 rotates, it simultaneously drives the turntable to rotate in the support base 7. A cover 4 is fixedly connected to the lower end of the support base 7, and a limit block is provided at the upper end of each of the five stirring rods 13. The cover 4 installed at the bottom of the support base 7 can limit the plastic material from splashing out when the stirring paddle 15 is stirring the plastic material, which can avoid waste and facilitate the user to collect the plastic material. The bottom edge of the stirring tank 3 has a rounded corner structure, and the front corner of the slide of the fixed platform 2 has a ramp. The rounded corner structure at the bottom of the stirring tank 3 can slide the stirring tank 3 into the groove of the fixed platform 2, so that the stirring paddle 15 can accurately position the stirring tank 3 to stir the plastic material. The ramp at the front of the slide allows the user to place the stirring tank 3 into the fixed platform 2.

[0023] As a second embodiment of this utility model: First, the mixing tank 3 is slid into the groove at the front end of the fixed platform 2. Then, plastic raw materials are introduced into the mixing tank 3. At the same time, two hydraulic cylinders 9 are operated to drive the mounting base 6 to move downward, so that the stirring paddle 15 is introduced into the mixing tank 3. Then, the motor 10 is operated to drive the first gear 11 to rotate, so that the inner and outer gear rings 12 rotate within the mounting base 6. The teeth on the inner wall of the inner and outer gear rings 12 drive the five second gears 17 to rotate. While the five stirring paddles 15 are mixing and stirring the plastic raw materials, the heating element inside can increase the mixing effect of the plastic raw materials. Finally, the two hydraulic cylinders 9 are controlled to push the mounting base 6 upward, and the user can then remove the mixing tank 3.
