EMBODIMENT
[0030] On the basis of the embodiment one, the preferable embodiment of the drying device for plastic particle processing and molding provided by the utility model is as follows Figures 1-4 As shown in the figure: the buffer stirring assembly 6 specifically comprises: a motor 611 fixedly installed at the top of the drying box 1; a connecting rod 612 arranged in the inside of the drying box 1; the output end of the motor 611 is fixedly installed with a rotating shaft, the other end of the rotating shaft is movably penetrated through the top of the drying box 1 and extends to the inside of the drying box 1 and is fixedly connected with one end of the connecting rod 612.

[0032] The outer wall of the connecting rod 612 is uniformly and equidistantly fixedly provided with an anti-sticking stirring rod four 619, and the other end of the anti-sticking stirring rod four 619 is fixedly provided with an anti-sticking scraper 6111, and the surface of the anti-sticking scraper 6111 is in contact with the inner wall surface of the drying box 1.
[0033] In this example, the buffer and stirring assembly 6 is arranged to buffer and stir, the falling particles fall into the anti-sticking buffer inclined ring two 616 through the anti-sticking buffer inclined ring one 614, and then fall into the anti-sticking buffer inclined ring three 618, and then further fall into the drying box 1, thereby minimizing the damage of the particles.

[0034] Working principle: first, remove the cover 512, and put the particles into the feeding pipe 511. The two buffer plates 513 and the rubber pad 514 buffer the falling particles to avoid the particles falling directly into the drying box 1. When it is necessary to adjust the angle of the buffer plate 513, the operator rotates the handle 516 to drive the threaded rod 517 to rotate, and the threaded rod 517 drives the threaded block 518 and the concave block two 519 to move.

The smaller the angle of the buffer plate 513, the longer the sliding time of the particles on the inclined plate, and the longer the friction time, and the better the buffering effect. Then, the falling particles fall into the anti-sticking buffer inclined ring three 618 through the anti-sticking buffer inclined ring two 616, and then further fall into the drying box 1, thereby minimizing the damage of the particles. The particles are buffered three times. When it is necessary to dry the particles, cover the cover 512 on the feeding pipe 511, and the hot air enters through the air inlet pipe 4 to dry the inside. Then, the motor 611 drives the connecting rod 612 to rotate, and drives the anti-sticking stirring rod one 613, the anti-sticking stirring rod two 615, the anti-sticking stirring rod three 617, and the anti-sticking stirring rod four 619 to uniformly stir the particles to avoid sticking. The anti-sticking stirring rod four 619 rotates and drives the anti-sticking scraper 6111 to clean the inner wall. After drying, the particles are discharged through the discharge pipe 3, thereby achieving the effect of buffer and buffer stirring.
