[0027] In some examples, the adjustment component 6 includes a rotating groove 61 and a rotating shaft 62. The rotating groove 61 is opened on the inner walls on both sides of the box body 1. The rotating shaft 62 is fixedly connected to both sides of one end of the baffle 3 and is rotatably connected to the rotating groove 61. The rotating shaft 62 can be rotated along the rotating groove 61 to adjust the angle of the baffle 3, thereby adjusting the residence time of the plastic particles on the baffle 3.

[0028] In some examples, the adjustment component 6 also includes a cavity 63, a first slide groove 64, a through hole 65, a pull rod 66, a first slider 67 and a first spring 68. The cavity 63 is opened inside the rotating shaft 62 on one side of the baffle 3, the first slide groove 64 is opened on the top and bottom inner walls of the cavity 63, the through hole 65 is opened inside the inner wall of the box body 1 and is connected to the rotating groove 61, the pull rod 66 is movably connected to the through hole 65 and passes through the inner wall of one side of the cavity 63 and extends into the cavity 63, and the first slider 67 is fixedly connected to the pull rod 6 6 and is slidably connected to the first slide groove 64. The first spring 68 is fixedly installed inside the cavity 63 and its two ends are respectively fixedly connected to one side of the first slider 67 and the inner wall of the other side of the cavity 63. The first slider 67 can be driven to rotate by rotating the pull rod 66. Since the first slide groove 64 is opened on the top and bottom inner walls of the cavity 63 and the first slider 67 is slidably connected to the first slide groove 64, the first slider 67 can drive the rotating shaft 62 to rotate through the first slide groove 64 and the cavity 63, thereby adjusting the angle of the baffle 3.

[0029] In some examples, the adjustment component 6 also includes a slot 69, a block 610 and a pull block 611. The slot 69 is opened on one side surface of the box body 1 and is connected to the through hole 65. The block 610 is fixedly connected to the outer periphery of the pull rod 66 near the outer end and is adapted to the size of the slot 69. The pull block 611 is fixedly connected to the outer end of the pull rod 66. The pull rod 66 can be rotated by removing the block 610 from the slot 69, and the pull rod 66 can be fixed in the current position by inserting the block 610 into the slot 69.

[0030] In some examples, the mounting assembly 9 includes a mounting groove 91, a mounting seat 92, a mounting hole 93, a connecting groove 94 and a mounting rod 95. The mounting groove 91 passes through the inner wall of one side of the box body 1 and is adapted to the size of the mounting block 8. The mounting block 8 is fixedly connected to the inner walls on both sides of the box body 1. The mounting hole 93 passes through the mounting block 8. The connecting groove 94 is opened inside the inner wall of the box body 1 and is connected to the mounting groove 91. The mounting rod 95 is movably connected to the connecting groove 94 and is adapted to the size of the mounting hole 93. The screen 7 is passed through the mounting groove 91 and placed on the top of the mounting seat 92. At this time, the mounting block 8 is in the mounting groove 91. Then, the mounting rod 95 is inserted into the mounting hole 93 to complete the installation of the screen 7.

[0031] In some examples, the mounting assembly 9 also includes a second slide groove 96, a second slider 97 and a second spring 98. The second slide groove 96 is opened on one side surface of the box body 1 and is connected to the connecting groove 94. The second slider 97 is fixedly connected to the top of the mounting rod 95 and is slidably connected to the second slide groove 96. The second spring 98 is fixedly installed inside the second slide groove 96 and its two ends are respectively fixedly connected to the top of the second slider 97 and the inner wall of the top of the second slide groove 96. Pulling the second slider 97 upwards can squeeze the second spring 98 and drive the mounting rod 95 to move upward. Release the second slider 97, and the second spring 98 rebounds to drive the mounting rod 95 to move downward through the second slider 97.

[0032] When the second slider 97 is released, the second spring 98 rebounds and drives the mounting rod 95 to move downward through the second slider 97. When the mounting rod 95 is inserted into the mounting hole 93 of the mounting block 8, the mounting block 8 can be fixed in the mounting groove 91, thereby completing the installation of the screen 7. Subsequently, the plastic particles that need to be finely separated are added into the box body 1 through the feed port 2. After the plastic particles enter the box body 1, they will first contact with the baffle plate 3. At the same time, the hot air blower 4 is started to send hot air into the box body 1 through the air inlet pipe 5 and dry the plastic particles. The dried plastic particles fall on the screen 7 for screening and flow out through the discharge port 11. When different plastic particles need to be finely separated, due to Different materials result in different drying times. At this time, the pull block 611 is pulled outward so that it drives the first slider 67 to slide outward along the first slide groove 64 through the pull rod 66 and stretch the first spring 68. In this process, the block 610 moves outward with the pull rod 66 until it moves out of the slot 69. The pull rod 66 is rotated to drive the first slider 67 to rotate. Since the first slot 64 is opened on the top and bottom inner walls of the cavity 63 and the first slider 67 is slidably connected to the first slot 64, the first slider 67 will drive the rotating shaft 62 to rotate through the first slot 64 and the cavity 63, thereby adjusting the angle of the baffle 3. After adjusting to the appropriate angle, the pull block 611 is released, the first spring 68 rebounds and drives the pull rod 66 to move inward through the first slider 67. When the block 610 moves inward with the pull rod 66 to be inserted into the slot 69, the pull rod 66 can be fixed in the current position, thereby completing the adjustment of the angle of the baffle 3. At this time, the drying time of the new material plastic particles can be changed.

[0033] By adopting the above technical solution: not only can the installation and disassembly of the screen be made simpler and faster, effectively improving work efficiency, but the drying time of the plastic particles can also be adjusted, so that the device can be suitable for plastic particles of different materials.

[0034] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the present invention.
