Description

Technical Field

[0001] The invention relates to the technical field of material processing, in particular to an automated granulation device and method based on the production of a polyolefin radiation cracking nucleating agent. Background Art

[0002] Polyolefin materials are widely used in the field of plastic processing due to their excellent physical and chemical properties.

[0003] Radiation cracking technology is an effective method for modifying polyolefin materials. By irradiating polyolefin materials with high-energy radiation sources, their molecular chains can be broken to form smaller molecular fragments, thereby changing their physical and chemical properties. Nucleating agent is an additive used to improve the crystallization properties of polymers. Adding an appropriate amount of nucleating agent to polyolefin materials can promote their crystallization process, increase the crystallization rate and crystallinity, thereby improving the mechanical properties and transparency of the material, and finally the raw materials are extruded.

[0004] However, in terms of raw material processing, traditional automated granulation devices based on the production of polyolefin radiation cracking nucleating agents often lack an effective crushing mechanism for polyolefins, resulting in uneven raw material particle size, which not only affects the efficiency of subsequent mixing and granulation, but also reduces the quality and stability of the product. Secondly, during the mixing process, it is difficult to ensure the mixing efficiency, and it is not convenient to filter the insufficiently mixed materials, resulting in direct granulation work, which affects the granulation effect. At the same time, during the stirring process, it is easy for materials to adhere to the inner wall of the mixing container, which not only affects the mixing effect, but also increases the difficulty of cleaning. In addition, traditional devices lack flexibility and adaptability in the granulation process. Once the extrusion mechanism is worn or the production demand changes, the entire device needs to be adjusted or replaced on a large scale, which is not only time-consuming and labor-intensive, but also reduces production efficiency. For this reason, the present invention provides an automated granulation device and method based on the production of polyolefin radiation cracking nucleating agents.

[0018] Step 2: The mixed material is filtered through the interior of the filter housing and enters the interior of the granulation housing.

[0019] Step 3: Finally, the granulating shell works to make the material be discharged through the extrusion mechanism.

[0020] The present invention provides an automated granulation device and method for producing a polyolefin radiation cracking nucleating agent. Compared with the prior art, it has the following beneficial effects:

[0021] Firstly, when the driving rod of the present invention is driven by the motor, the transmission rod is also driven to rotate, so that the crushing shaft inside the crushing shell rotates, and the polyolefin entering the crushing shell is crushed, which can ensure that the particle size of the polyolefin meets the requirements of subsequent mixing and granulation. By first crushing the polyolefin, the efficiency of subsequent mixing and granulation is significantly improved. The crushed polyolefin particles are smaller and more uniform, which is conducive to sufficient mixing with the nucleating agent, thereby improving the quality and stability of the product.

[0022] Secondly, the stirring rod on the outer wall of the connecting rod of the present invention rotates inside the mixing shell to achieve stirring of the polyolefin radiation cracking nucleating agent mixed material, effectively promotes the uniform mixing of the polyolefin radiation cracking nucleating agent mixed material, improves the mixing efficiency, helps to improve the mixing uniformity of the material, and can also ensure that various components are evenly distributed in the material, thereby improving the quality and stability of the product. At the same time, the scraper bracket connected to the outer wall of the connecting rod through the fixed rod rotates in a close fit on the inner wall of the mixing shell, which can continuously scrape off the material attached to the inner wall, ensuring that the material is always in a flowing state, further improving the mixing effect, ensuring that the material is mixed without dead angles, avoiding material accumulation, enhancing the mixing quality, and facilitating the cleaning of residual materials. At the same time, the sliding shaft slides in the annular groove inside the slide plate, thereby The slide plate slides back and forth inside the side wall of the filter bracket, and the filter housing inside the filter bracket is shaken to filter the mixed polyolefin radiation cracking nucleating agent mixture. During the shaking process, the material is subjected to a more uniform force to ensure that fine particles can also be effectively filtered and to effectively prevent clogging of the filter medium. The filtered material is sent to the granulation housing for the next step. Due to the effective filtration, the purity and uniformity of the granulation raw materials are ensured, which helps to improve the quality and performance of the final granulation product. The incompletely mixed material will be taken out of the filter housing and mixed and stirred again to remove the incompletely mixed particles in the mixed material, thereby ensuring that the material entering the granulation housing is pure and uniform, which helps to improve the granulation efficiency and granulation quality and reduce production costs.

[0023] Thirdly, the present invention crushes the polyolefin and then feeds it into a mixing shell, adds a nucleating agent into the mixing shell, stirs and mixes the crushed polyolefin and the nucleating agent, filters the stirred and mixed polyolefin and the nucleating agent, filters the fully mixed polyolefin into a granulation shell, extrudes the polyolefin through an extrusion mechanism, and continues to crush and mix the polyolefin that is not fully mixed. The automated process reduces manual intervention and speeds up the production process. From the crushing, mixing, filtering to granulation of the polyolefin, the entire production line realizes continuous operation, which significantly improves production efficiency.

[0024] Fourthly, the polyolefin radiation cracking nucleating agent mixture provided in the present invention is fed into the interior of the granulation shell, and the material is extruded and formed by an extrusion mechanism. The extrusion mechanism is connected to the front end of the granulation shell by a flange and bolts, which is convenient for disassembly and replacement of the extrusion mechanism. In the actual production process, as the production demand changes or the extrusion mechanism wears out, the extrusion mechanism can be adjusted or replaced, which can quickly adapt to different production demands and improve production efficiency. When the material is discharged, the cutting knife is rotated by a motor to evenly cut the material discharged by the extrusion mechanism, thereby ensuring the uniformity and consistency of the granulation and improving the quality and stability of the product.

Specifically, the driving rod 7 and the transmission rod 10 are connected through a chain and a sprocket transmission. When the driving rod 7 is driven by the motor, the transmission rod 10 is driven to rotate at the same time, so that the crushing shaft 1001 inside the crushing shell 303 rotates, so that the polyolefin entering the crushing shell 303 is crushed, which can ensure that the particle size of the polyolefin meets the requirements of subsequent mixing and granulation, thereby improving the quality and stability of the product, and then feed it into the mixing shell 3 The inside of 02 is used to add a nucleating agent through the feed port 8, and the added material is controlled by observing the scale on the outer wall of the feed port 8, so that the operator can easily control the amount of nucleating agent added, and when polyolefin is fed into the crushing shell 303, the polyolefin is accurately poured between the two groups of crushing shafts 1001 through the guide plate 1002, thereby improving the crushing efficiency and crushing effect, and the cleaning plate 1003 fixed on the inner wall of the crushing shell 303 and the cleaning plate 1003 attached to the outer wall of the crushing shaft 1001 are used to clean the residual polyolefin in the crushing, and the cleanliness of the crushing shaft 1001 is ensured.
