Description

Technical Field

[0001] This utility model relates to the field of modified plastics processing technology, and in particular to a modified plastic granule drying device. Background Technology

[0002] Modified plastic granule drying equipment is a pretreatment device specifically designed to remove surface and internal moisture from plastic granules. Before plastic processing, it is essential to ensure the raw materials are thoroughly dried to avoid defects such as bubbles, silver streaks, and reduced strength. This equipment uses methods such as heating, dehumidification, or vacuum to bring the plastic granules to the required moisture content for the process, ensuring the quality of subsequent molding.

[0003] Patent CN219855489U discloses a drying device for producing modified plastic particles. By incorporating a stirring device, the modified plastic particles inside the drying cylinder can rotate, thus preventing them from accumulating at the bottom. A blowing device allows hot air to diffuse along the rotating shaft, facilitating rapid heat dissipation. A discharge pipe and tilting device allow the drying cylinder to tilt after drying, causing the modified plastic particles to slide down into the discharge pipe for collection. However, in practice, the stirring device typically only stirs the modified plastic particles in one direction, resulting in a limited stirring method. Furthermore, during stirring, some plastic particles between the stirring rods tend to remain stationary and cannot be moved, thus reducing the drying efficiency and effectiveness of the device. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a modified plastic granule drying device. When the existing modified plastic granule drying device is in use, its stirring device can usually only stir the modified plastic granules in one direction. The stirring method is relatively simple. Moreover, during the stirring process, some plastic granules between the stirring rods tend to stand still and cannot be moved, which will reduce the drying efficiency and effect of the device.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is a modified plastic granule drying device, including a fixed vertical plate fixedly connected to a support base, and a rotating shaft that movably passes through the fixed vertical plate. A rotating cylinder is fixedly connected to the end of the rotating shaft, and an end cap is provided at the other end of the rotating cylinder. An inner serrated ring is fixedly connected to the edge of the end cap.

[0006] The bearing base is provided with a movable vertical plate at the end away from the fixed vertical plate. The top of the movable vertical plate is rotatably connected to a rotating mesh tube and a linkage shaft. A central gear and a linkage gear are respectively locked and sleeved on the rotating mesh tube and the linkage shaft.

[0015] As a further embodiment of this utility model: the cross-sectional shape of the guide plate is U-shaped, and the lower end of the guide plate is connected to the collection box.

[0016] Compared with the prior art, the beneficial effects of this utility model include: by starting the first motor on the outside of the fixed vertical plate, the rotating shaft and rotating cylinder are driven to rotate together, thereby driving the end cover and inner serrated ring to rotate together under the cooperation of the movable ring and the annular groove. Then, the linkage gear on the outside of the linkage shaft drives the central gear to rotate in the opposite direction, thereby driving the rotating mesh tube to rotate in the opposite direction. Then, under the cooperation of several sets of connecting rods, four sets of long scrapers are driven to rotate in the opposite direction. The bidirectional rotation method realizes the function of rapid drying of modified plastic particles, and the drying process has no dead corners, which significantly improves the drying effect of modified plastic particles.

[0017] Compared with the prior art, the beneficial effects of this utility model include: by starting the second motor on one side of the support base, the lead screw shaft is driven to rotate, thereby driving the moving vertical plate to move laterally through the threaded connection between the lead screw shaft and the moving column and the limiting groove.

The plastic particles are then guided into the inside of the collection box through the guide plate, realizing the convenient discharge function of modified plastic particles, with a fast discharge rate and improved work efficiency.
