[0020] See also Figure 1-4 The utility model provides a drying device for processing plastic particles, including a drying box 1, a hot air duct 2 for conveying hot air into the drying box 1 at the top of the drying box 1, a bottom plate 3 is arranged in the drying box 1, a shaking mechanism for making the bottom plate 3 move back and forth is arranged on the drying box 1, a placing box 4 for storing plastic particles is placed on the bottom plate 3, and a clamping mechanism for fixing the placing box 4 is also arranged on the bottom plate 3. Through such a design, the plastic particles to be dried can be poured into the placing box 4 for storage, and the placing box 4 is placed on the bottom plate 3 and fixed on the bottom plate 3 by the clamping mechanism. At this time, the hot air duct 2 can convey hot air into the drying box 1 and dry the plastic particles at high temperature. At the same time, under the action of the shaking mechanism, the bottom plate 3 and the placing box 4 will be driven to move back and forth, so that the plastic particles can be continuously shaken and turned in the placing box 4, ensuring that the plastic particles can be evenly contacted with the hot air, so as to achieve the effect of uniform heating and drying.

[0021] In order to be able to fix the placement box 4 on the base plate 3, it is proposed that the clamping mechanism includes two movable plates 5 which are symmetrically arranged on the top of the base plate 3 and can move in opposite directions. Positioning grooves 6 are provided on both sides of the placement box 4. Positioning blocks 7 corresponding to the positioning grooves 6 are fixedly connected to the two movable plates 5. After the placement box 4 is placed on the base plate 3, the two movable plates 5 can be respectively located on both sides of the placement box 4. At this time, when the two movable plates 5 move towards each other, the positioning blocks 7 can be inserted into the positioning grooves 6, thereby fixing the position of the placement box 4.

[0022] The specific method for enabling the two movable plates 5 to move in opposite directions is as follows: a slide groove 8 is provided at the top of the bottom plate 3 along its length direction, and a bidirectional threaded rod 9 is rotatably connected to the slide groove 8 in a left-right axial direction through a bearing, and the bottoms of the two movable plates 5 are both inserted in the slide groove 8, and the two sides of the bidirectional threaded rod 9 are respectively inserted into the bottom of the two movable plates 5 through the cooperation of the forward thread and the reverse thread, and a servo motor 10 is fixedly installed on one side of the bottom plate 3, and one side of the bidirectional threaded rod 9 penetrates the bottom plate 3 and is fixedly connected to the end of the output shaft of the servo motor 10. The output shaft of the servo motor 10 drives the bidirectional threaded rod 9 to rotate when it rotates, so that the bidirectional threaded rod 9 can drive the two movable plates 5 to move in opposite directions along the slide groove 8 through the cooperation of the forward thread and the reverse thread, so as to fix / release the position of the placement box 4.

[0023] See also Figure 4 Four symmetrical fixing blocks 11 are fixedly connected to the bottom of the inner wall of the drying box 1, and a guide rod 12 is fixedly connected between every two front-to-back symmetrical fixing blocks 11, and the two sides of the bottom of the bottom plate 3 are respectively slidably sleeved on the two guide rods 12, so that the bottom plate 3 can form a snap-fit ​​sliding connection along the front-to-back direction in the drying box 1, which is more reasonable.

[0024] At the same time, in order to enable the bottom plate 3 to move back and forth, the shaking mechanism includes a servo motor 16 fixedly installed on the back of the drying box 1 with the output shaft facing downward, the end of the output shaft of the servo motor 16 is fixedly connected to the circular plate 14, and the back of the bottom plate 3 is fixedly connected to a connecting rod 13 inserted into the back of the bottom plate 3, and the connecting rod 13 is rotatably connected to a push rod 15 on one side outside the bottom plate 3, and the push rod 15 is rotatably connected to the non-center point of the bottom of the circular plate 14 away from the side of the connecting rod 13, and the servo motor 16 can drive the circular plate 14 to rotate, so that one side of the push rod 15 can rotate along the axial direction of the circular plate 14, and the other side of the push rod 15 will push the connecting rod 13 to move back and forth, so that the bottom plate 3 can drive the placement box 4 and the plastic particles in the placement box 4 to shake back and forth.

[0025] Furthermore, a placement groove 41 is opened at the top of the placement box 4, so that the plastic particles can be poured into the placement groove 41, and two left-right symmetrical handles 42 are fixedly connected to the front of the placement box 4 to facilitate the staff to hold the handles 42 and take the placement box 4 out of the drying box 1.

[0026] Furthermore, the placement groove 41 is constructed into a 2 / 3 columnar structure inside the placement box 4, so that the inner wall of the placement groove 41 is an arc surface, allowing the plastic particles to be shaken and rolled more easily inside.
