Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically to a granule drying device for modified plastics production. Background Technology

[0002] A granule drying device for modified plastics production is a piece of equipment used to dry modified plastic granules. Its main purpose is to remove moisture from the granules and improve their dryness and quality.

[0003] The particles in the material are not uniform, generally varying in size. During drying, workers typically pour a batch of material into a drying drum, which is then dried by airflow from the bottom. Because the drum is stationary, the material accumulates at the bottom. The airflow from the bottom continues to dry the material. However, since the material is being dried statically, the material closer to the airflow dries faster, while the material further away dries more slowly. The upper layer of material and larger particles require a longer drying time. Insufficient drying time will result in incompletely dried material causing defects during subsequent processing, affecting the product's appearance quality. Utility Model Content

[0031] Preferably, the clamping mechanism includes:

[0032] The top of the rotating ring is symmetrically and fixedly connected with two support pillars;

[0033] A support plate is fixedly connected to the other end of the two pillars;

[0042] In this invention, when using a granule drying device to dry modified plastics, because the plastic granules are of varying sizes and all piled up in the drying drum, a longer drying time is required. At this point, the worker needs to rotate the rotating support mechanism to the side away from the drying drum, then open the opening and closing assembly, pour all the plastic granules into the storage box, close the opening and closing mechanism, start the rotating mechanism to rotate the storage box 90 degrees, then start the tumbling mechanism to tumble the storage box. Simultaneously, the dryer fan is started to tumble the plastic material in the tumbling storage box. After processing... After drying, because the plastic granules are quite hot, the worker opens the opening and closing components, then rotates the rotating support mechanism back to the top of the drying drum, and activates the clamping mechanism. The clamping mechanism holds the storage box and lifts it upward. When lifted upward, the rebound ejection mechanism pushes the storage box upward, allowing it to leave the tumbling mechanism. After completely leaving, the rebound ejection mechanism can automatically return to its initial state. Compared with existing technologies, this method allows for tumbling and drying of plastic materials, ensuring that most plastic materials are fully dried, reducing the occurrence of incompletely dried plastic materials, and improving the product quality of plastic materials.

The electric cylinder 503 is retracted, and the storage frame 4 is taken out. As the storage frame 4 rises, it will collide with the ejector plate 302. Due to the elastic deformation of the spring 301, the ejector plate 302 will unfold upward. After the storage frame 4 is completely out, the ejector plate 302 will spring back to its initial state according to the elastic deformation of the spring 301. Then, the next batch of plastic granules can be dried in the same way.
