[0022] After the plastic particles are conveyed to the top of the rotating plate 7 through the feed port 3, the plastic particles will move along the inclination direction of the rotating plate 7 and finally fall to the top of the conveying plate 9, and finally be discharged from the conveying plate 9 to the position of the discharge port 8, and discharged through the discharge port 8. In the process of the plastic particles moving on the rotating plate 7, the hot air blower 2 is started to convey hot air to the surface of the plastic particles moving toward the discharge port 8 to dry the moisture on the plastic particles. In the process of the plastic particles moving, the guard plate 10 is used to prevent the plastic particles from falling from both sides of the top of the rotating plate 7;

[0023] A connecting rod 11 is fixedly installed on one side of the outer peripheral wall of the rotating rod 15 near the drying box 1, and a rotating rod 2 12 is rotatably installed on one side of the drying box 1 near the connecting rod 11. The length of the rotating rod 2 12 is less than the length of the connecting rod 11, and a driving motor for driving the rotating rod 2 12 to rotate is installed on the drying box 1. The end of the rotating rod 2 12 away from the driving motor is rotatably connected to the end of the connecting rod 11 away from the rotating rod 15. When the rotating rod 2 12 continues to rotate, the rotating rod 2 12 will drive the rotating rod 15 to reciprocate within a certain rotation angle through the connecting rod 11, so that the rotating rod 15 drives the rotating plate 7 to swing back and forth with the rotating rod 15 as the rotating axis through the multiple supporting plates 26;

[0024] A plurality of pairs of water-absorbing sponges 13 are provided through the rotating plate 7, and the opposite side of each pair of water-absorbing sponges 13 is fixedly connected to the rotating plate 7 by a fixed plate 14, and an extrusion plate 15 is fixedly installed on the opposite side of each pair of water-absorbing sponges 13 at the same time, and a traction plate 16 is slidably installed at the bottom of the rotating plate 7, and the traction plate 16 is fixedly connected to multiple extrusion plates 15 at the same time, and two mutually symmetrical connecting plates 17 are fixedly installed on one side of the traction plate 16 with the rotating rod 15 as the central axis, and a slide groove 18 is provided on the connecting plate 17, and a slide rod 19 is slidably installed in the slide groove 18, and a push-pull plate 20 is fixedly installed at one end of the slide rod 19, and the end of the push-pull plate 20 away from the slide rod 19 is rotatably connected to the inner wall of one side of the drying box 1;

[0025] When the rotating plate 7 reciprocates within a certain rotation angle with the rotating rod 15 as the rotating axis, the horizontal plane of the traction plate 16 is reciprocated and deflected. When the traction plate 16 is deflected in the horizontal plane, the two connecting plates 17 move toward each other for a certain distance in the vertical direction and the horizontal direction. The push-pull plate 20 slides in the slide groove 18 along its own extension direction through the slide rod 19 to correct its position relationship with the connecting plate 17 in the horizontal direction, and slides along the track of the slide groove 18 through the slide rod 19 to correct its position relationship with the connecting plate 17 in the vertical direction. During this process, the two push-pull plates 20 are rotated toward each other through the two sliding rods 19 under the action of the two connecting plates 17, thereby driving the traction plate 16 to slide back and forth at the bottom of the rotating plate 7, so that the traction plate 16 drives the plurality of squeezing plates 15 to reciprocate and squeeze multiple pairs of water-absorbing sponges 13, so that the two water-absorbing sponges 13 in each pair of water-absorbing sponges 13 are respectively in an expanded and contracted state, so that one water-absorbing sponge 13 in each pair of water-absorbing sponges 13 is used to absorb water from the plastic, and the other is used to discharge the internal moisture.

[0026] When the utility model is in use, the cleaned plastic particles are transported from the feed port 3 to the top of the rotating plate 7, and then the rotating plate 7 is reciprocated within a certain rotation angle with the rotating rod 15 as the rotating axis, so that the plastic particles on the top of the rotating plate 7 move along the inclined surface of the rotating plate 7 to the discharge port 8, and also reciprocate left and right on the top of the rotating plate 7, so that the plastic particles are fully rolled and fully contacted with the hot air blown by the hot air blower 2, so as to improve the drying efficiency of the plastic particles, and at the same time, the plastic particles are fully rolled on the multiple pairs of water-absorbing sponges 13, so that the water-absorbing sponges 13 can fully absorb the moisture on the surface of the plastic particles. While the rotating plate 7 reciprocates within a certain rotation angle with the rotating rod-5-position rotating shaft, the traction plate 16 is acted upon by the sliding rods 19 at one end of the two push-pull plates 20 sliding in the slide grooves 18 of the two connecting plates 17, so that it slides back and forth at the bottom of the rotating plate 7, thereby driving the multiple squeezing plates 15 to alternately squeeze two water-absorbing sponges 13 in multiple pairs of water-absorbing sponges 13, so that the two water-absorbing sponges 13 in each pair of water-absorbing sponges 13 are respectively in an expanded and contracted state, so that each pair of water-absorbing sponges 13 is used to absorb moisture on the surface of the plastic particles while discharging the moisture absorbed inside.
