[0002] A drying device for plastic granule production is mainly used to remove moisture or solvents from plastic granules during the production process, ensuring that quality problems are not caused by moisture or residual solvents in subsequent processing. The plastic granule drying device is one of the key pieces of equipment in a plastic production line, typically used in the raw material preparation stage before processes such as injection molding, extrusion, and blow molding. The drying device for plastic granule production plays a vital role in the plastics industry, ensuring that the plastic granules maintain optimal dryness during processing through a highly efficient hot air heating and control system, effectively improving the quality and efficiency of subsequent processing steps.

[0014] (III) Beneficial Effects

[0015] This utility model provides a drying device for plastic granule production, which has the following beneficial effects:

[0016] 1. This drying device for plastic granule production, through the setting of the push component, when it is necessary to discharge the dried plastic granules, the hydraulic push rod is activated, causing the hydraulic push rod to push the rotating ring, so that the rotating ring rotates on the surface of the movable bolt. At the same time, the other end of the hydraulic push rod rotates on the fixed seat, thereby driving one side of the base to rise, while the rotating bolt on the other side rotates on the surface of the rotating seat, thereby achieving the effect of adjusting the tilt angle of the main body of the drying cylinder. It can flexibly adjust the flow speed of plastic granules under the action of gravity, thereby matching different production needs, and can effectively reduce the residue of granules on the cylinder wall or bottom.

[0017] 2. This drying device for producing plastic granules, through the setting of the support components, allows plastic granules to be fed into the main body of the drying cylinder during use. The main body of the drying cylinder is driven to rotate by the drive device in the base, which in turn starts the drive motor, causing the drive motor to drive the rotating shaft to rotate in the opposite direction. The rotating shaft then drives the support sleeve to rotate, and the rotation of the support sleeve causes the telescopic rod and scraper to rotate. At the same time, when the scraper is pressed, the telescopic rod slides in the support sleeve, squeezing the support spring. The elastic force offsets part of the pressure, thereby achieving the effect of fully stirring the internal plastic granules and improving the drying efficiency. Attached Figure Description
