Description

Technical Field

[0001] This utility model relates to the field of additive delivery, specifically a polyolefin solid additive delivery device. Background Technology

[0002] In the production of polyolefins, various solid additives, such as antioxidants, light stabilizers, and antistatic agents, are often added to improve product performance and meet specific market demands. Accurate metering of these additives is crucial for ensuring product quality and performance. However, existing polyolefin solid additive conveying devices generally suffer from a problem: the additives are not weighed during the conveying process.

[0003] Due to the lack of real-time weighing and metering functions, operators usually need to remove the additive from the conveying device after it has been delivered and weigh it using a separate weighing device. This process is not only time-consuming and labor-intensive, but also prone to errors due to the uncertainty of human operation, which affects the quality and performance of the product. In addition, frequent weighing operations also increase maintenance costs and workload, and reduce production efficiency. To address these issues, we provide a polyolefin solid additive conveying device. Utility Model Content

[0016] An embodiment of the present invention is shown in conjunction with the accompanying drawings.

[0017] A polyolefin solid additive conveying device includes a support platform 1. Two support frames 6 are mounted on the upper surface of the support platform 1. A storage box 11 is mounted on one side of the two support frames 6 that are close to each other. A weighing box 13 is mounted on the upper surface of the storage box 11. A crushing box 12 is mounted on the bottom surface of the storage box 11. A weighing plate 15 is rotatably mounted inside the weighing box 13. A motor A14 is mounted on the outer surface of the weighing box 13. The output end of the motor A14 passes through the weighing box 13 and is connected to the outer surface of the weighing plate 15. Two rotating shafts 23 are rotatably mounted inside the crushing box 12. Multiple crushing blades 24 are mounted on the outer surface of each rotating shaft 23. Two motors B22 are mounted on the outer surface of the crushing box 12. The output end of each motor B22 passes through the crushing box 12 and is connected to the right end of the rotating shaft 23.

[0018] In this embodiment, the outer surface of the crushing box 12 is connected to a discharge pipe 21, and an electric control valve 20 is installed on the outer surface of the discharge pipe 21. The use of the electric control valve 20 and the discharge pipe 21 together helps to control the feeding rate.

[0019] In this embodiment, an installation block 16 is installed on the outer surface of the storage box 11, and the left side of the installation block 16 extends through one of the support frames 6 and extends to the left side of the support frame 6.

[0020] In this embodiment, the mounting block 16 has an internal mounting groove 17, and an electric push rod 18 is installed inside the mounting groove 17. A sealing plate 19 is installed at the output end of the electric push rod 18. The electric push rod 18 and the sealing plate 19 work together to seal the discharge port of the storage box 11, so that the pulverized additives are discharged and then the material is discharged again, thus avoiding the situation where excessive additives reduce the pulverization efficiency.

[0021] In this embodiment, a receiving frame 5 is installed on the upper surface of the support platform 1, and an installation frame 7 is installed on the outer surface of the receiving frame 5 and the outer surface of one of the support frames 6.

[0022] In this embodiment, two rotating rods 10 are rotatably mounted inside the mounting frame 7, and the outer surfaces of the two rotating rods 10 are connected to a conveyor belt 8 for transmission.

[0023] In this embodiment, a conveyor motor 9 is installed on the outer surface of the mounting frame 7. The output end of the conveyor motor 9 passes through the mounting frame 7 and is connected to the front end of one of the rotating rods 10. The conveyor motor 9 drives the conveyor belt 8 to transport the additives, which can reduce the steps of manual handling and has the advantages of saving time and effort.

[0024] In this embodiment, four support legs 2 are installed on the bottom surface of the support platform 1, and each support leg 2 is equipped with a moving wheel 3 at its bottom end. A controller 4 is installed on the outer surface of the support platform 1.

The controller 4 starts the conveyor motor 9 to drive the rotating rod 10 and the conveyor belt 8 to rotate, thereby conveying the additive inside the receiving frame 5 into the weighing box 13. The additive falls into the weighing plate 15 through the feed port of the weighing box 13. The weigher installed inside the weighing plate 15 weighs the additive. After weighing, the motor A14 is started to drive the weighing plate 15 to rotate to a vertical position, so that the weighed additive falls into the storage box 11 for storage. The discharge pipe 21 is aligned with the designated conveying position, and the electric push rod 18 is started to drive the sealing plate 19 to open the discharge port of the storage box 11. The motor B22 is started to drive the rotating shaft 23 and the crushing blade 24 to crush large pieces of solid additive to avoid blockage in the subsequent feeding process. Finally, the discharge is carried out by the cooperation of the discharge pipe 21 and the electric control valve 20.

[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
