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.
[0035] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a modular PS plastic particle precision color mixing device, including a support 1. A connecting pipe 12 is fixedly connected to the top of the support 1. The connecting pipe 12 can smoothly guide the plastic particles conveyed from above to the stirring component below. An anti-overflow frame 14 is installed on the top of the connecting pipe 12. The anti-overflow frame 14 can effectively block the plastic particles that may splash out during the feeding process, avoiding material waste and pollution of the surrounding environment. A feeding hopper 17 is installed on the top of the anti-overflow frame 14. A metering component is installed inside the feeding hopper 17. The component can strictly control the speed and quantity of plastic particles entering the subsequent process. A stirring tank 2 is installed inside the support 1. The stirring tank 2 is located at the bottom of the connecting pipe 12. The plastic particles complete the key color mixing process in the stirring tank 2. A stirring component is installed inside the stirring tank 2. The stirring component ensures that the plastic particles can be mixed evenly.
[0036] The metering component includes a motor 19, which provides power for metering feed. The motor 19 is fixedly connected to one side of the feed hopper 17. A rotating shaft 20 is fixedly connected to the output end of the motor 19. The rotating shaft 20 is rotatably connected inside the feed hopper 17. After the motor 19 starts, it can drive the rotating shaft 20 to rotate stably inside the feed hopper 17. A metering roller 21 is fixedly connected to the outside of the rotating shaft 20. Multiple metering baffles 22 are fixedly connected to the outer periphery of the metering roller 21. When the rotating shaft 20 rotates, it will drive the metering roller 21 and the metering baffles 22 to rotate together, thereby achieving precise control of the feed amount. A protective box 18 is fixedly connected to one side of the feed hopper 17. The motor 19 is installed inside the protective box 18. The protective box 18 can provide effective protection for the motor 19 and reduce the impact of external dust, debris and other objects on the motor 19. The interior of each of the multiple metering baffles 22 is provided with a groove 23. The groove 23 is mainly to better grasp the plastic particles and prevent the plastic particles from slipping out and causing waste.
[0037] Reference Figure 1 , Figure 5 and Figure 6The stirring assembly includes a second motor 4, which is fixedly connected to the bottom of the stirring tank 2. The second motor 4 can stably output power. A rotating rod 7 is fixedly connected to the output end of the second motor 4. After the second motor 4 is started, it can drive the rotating rod 7 to rotate. A scraper frame 5 is fixedly connected to the outside of the rotating rod 7. When the rotating rod 7 rotates, it will drive the scraper frame 5 to rotate inside the stirring tank 2, which can stir the particles near the edge of the stirring tank 2 and avoid particles from accumulating in corners, which will cause color difference in the product. Multiple inclined blades 6 are fixedly connected inside the scraper frame 5. A mounting box 3 is fixedly connected to the bottom of the stirring tank 2. The mounting box 3 provides installation space for the second motor 4 and also protects the second motor 4. The second motor 4 is installed inside the mounting box 3.
[0038] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 The top of the connecting pipe 12 is provided with an installation groove 13, and the bottom of the anti-overflow frame 14 is fixedly connected with an installation block 15. The installation block 15 is inserted into the installation groove 13. Through the cooperation of the installation block 15 and the installation groove 13, the anti-overflow frame 14 and the connecting pipe 12 are conveniently installed and fixed, ensuring the stability of the connection between the two. The top of the anti-overflow frame 14 is provided with a connecting block 16, and the other side of the connecting block 16 is installed on one side of the feed hopper 17. The connecting block 16 serves to connect and fix the feed hopper 17 and the anti-overflow frame 14.
[0039] A fixing plate 10 is fixedly connected to the outside of the mounting box 3. Multiple bolts 11 are threadedly connected to the fixing plate 10 and the bracket 1. The fixing plate 10 and the bracket 1 are fixedly connected by the bolts 11, thereby stably mounting the mounting box 3 and the internal motor 4 on the bracket 1. A discharge pipe 8 is fixedly connected to the bottom of the mixing tank 2. The plastic particles after mixing and coloring can be discharged from the equipment through the discharge pipe 8. A solenoid valve 9 is installed in the middle of the discharge pipe 8. The solenoid valve 9 can control the opening and closing of the discharge pipe 8. A flange ring 24 is fixedly connected to the bottom of the mixing tank 2. Multiple bolts 25 are threadedly connected to the flange ring 24 and the bracket 1. The flange ring 24 is fixed to the bracket 1 by the bolts 25, which further enhances the stability of the connection between the mixing tank 2 and the bracket 1, making the mixing tank 2 more stable and reliable during operation.
[0040] Working principle: First, the required plastic particles are poured into the feed hopper 17. In the initial state, the groove 23 just blocks the feed hopper 17 to prevent the internal material from falling. After setting the feeding speed, the motor 19 is started. The motor 19 drives the rotating shaft 20 to rotate, the rotating shaft 20 drives the metering roller 21 to rotate, and the metering roller 21 drives the metering baffle 22 to rotate, so that the feeding can be strictly in accordance with the set speed, making the feeding process more stable. Stable feeding can make the mixing more uniform. At the same time, the setting of the groove 23 helps to better control the plastic particles.
[0041] Secondly, after the plastic particles enter the mixing tank 2, the motor 4 is started. The motor 4 drives the scraper frame 5 and the inclined blade 6 to rotate. The scraper frame 5 can stir the particles near the edge to avoid the particles from accumulating in the corners and causing color difference in the product. The inclined blade 6 is tilted at a certain angle and has an upward trend when rotating, which can continuously convey the plastic particles upward to achieve multiple stirrings, thereby efficiently stirring the material evenly.
[0042] Then, both the mixing component and the metering component can be disassembled, replaced and assembled separately, which facilitates subsequent maintenance and repair, and realizes the modularization of equipment.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
