[0025] The following will be combined with the drawings of the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a plastic particle drying device, comprising a drying box 1, the inner wall of the drying box 1 is fixedly connected with a bottom plate 5, the interior of the bottom plate 5 is slidably connected with a first sliding column 6, the outer wall of the first sliding column 6 is slidably connected with a spring 7, the interior of the first sliding column 6 is fixedly connected with a first fixed column 8, the outer wall of the first fixed column 8 is fixedly connected with a vibration bar 9, the upper surface of the vibration bar 9 is fixedly connected with a drying box 16, the outer wall of the drying box 1 is fixedly connected with an outer box 2, the interior of the outer box 2 is provided with a motor 3, the output end of the motor 3 is fixedly connected with a cylindrical rod 4, the outer wall of the cylindrical rod 4 is fixedly connected There is a fixing ring 10, the outer wall of the fixing ring 10 is fixedly connected with a connecting strip 11, the inside of the connecting strip 11 is fixedly connected with a second fixing column 12, the outer wall of the second fixing column 12 is rotatably connected with a rotating wheel 13, the outer wall of the rotating wheel 13 is slidably connected to the outer wall of the vibration strip 9, and a supporting assembly is provided on the upper surface of the bottom plate 5; the supporting assembly includes a slide cylinder 14, the lower surface of the slide cylinder 14 is fixedly connected to the upper surface of the bottom plate 5, the inside of the slide cylinder 14 is slidably connected with a second slide column 15, the top end of the second slide column 15 is fixedly connected to the lower surface of the drying box 16, and the lower surface of the bottom plate 5 is fixedly connected with a supporting leg 31;

[0027] Specifically, the motor 3 starts and drives the cylindrical rod 4 to rotate inside the drying box 1, wherein the drying box 1 fixes the outer box 2, and the outer box 2 fixes the motor 3, which can improve the stability of the motor 3 during operation. The cylindrical rod 4 rotates and drives the fixing ring 10 to rotate, and then drives the connecting bar 11 and the second fixing column 12 to rotate, so that the rotating wheel 13 rotates. When the rotating wheel 13 rotates, it presses the vibration bar 9 to move downward, so that the vibration bar 9 drives the first sliding column 6 and the first fixing column 8 to move downward, and then the vibration bar 9 presses the spring 7 to contract, and at the same time, the first sliding column 6 slides inside the bottom plate 5. Since the drying box 16 is fixedly connected to the vibration bar 9, the vibration bar 9 also drives the drying box 16 to move downward when it moves downward. The drying box 16 When moving downward, the second slide post 15 is driven to slide on the inner wall of the slide cylinder 14. When the rotating wheel 13 rotates and passes the outer wall of the vibration bar 9, the vibration bar 9 is no longer subjected to external pressure. At this time, the spring 7 rebounds and pushes the vibration bar 9 to move upward, thereby causing the first slide post 6 to move upward and slide again inside the bottom plate 5, wherein the bottom plate 5 limits the first slide post 6, and the first fixed column 8 fixes the vibration bar 9. The slide cylinder 14 is fixed on the upper surface of the second slide post 15 and the second slide post 15 slides inside the slide cylinder 14, which together support the drying box 16 and prevent the drying box 16 from deflecting during repeated movements. The vibration bar 9 moves upward to prompt the drying box 16 to move upward, and this is repeated, so that the drying box 16 is always in a vibrating state.

[0028] Reference Figure 1 The outer wall of the drying box 1 is provided with a box door 17, the inner wall of the drying box 1 is fixedly connected with a top plate 18, the inner wall of the top plate 18 is fixedly connected with a fixing box 19, and the interior of the fixing box 19 is fixedly connected with a first fixing plate 20;

[0029] Specifically, the drying box 1 plays a role of fixing and connecting the box door 17 , the top plate 18 plays a role of fixing the fixing box 19 , and the fixing box 19 plays a role of fixing the first fixing plate 20 .

[0030] Reference Figure 1 , Figure 3 and Figure 4The interior of the fixed box 19 is fixedly connected with a second fixed plate 21, the interior of the first fixed plate 20 is rotatably connected with a rotating column 22, the top of the rotating column 22 is fixedly connected with a knob 23, and the outer wall of the rotating column 22 is fixedly connected with an eccentric wheel 25; the outer wall of the rotating column 22 is fixedly connected with a gear 24, the outer wall of the eccentric wheel 25 is fixedly connected with a connecting frame 26, and the interior of the connecting frame 26 is fixedly connected with a third fixed column 27; the interior of the third fixed column 27 is slidably connected with a sliding column 28, and the outer wall of the sliding column 28 is slidably connected with a limiting plate 29; the upper surface of the limiting plate 29 is fixedly connected to the lower surface of the second fixed plate 21, the outer wall of the sliding column 28 is slidably connected to the interior of the fixed box 19, and a heating plate 30 is provided on the lower surface of the top plate 18; the outer wall of the sliding column 28 is slidably connected to the interior of the heating plate 30;

[0031] Specifically, the drying box 1 is fixedly connected to the top plate 18, and the drying box 1 can fix the top plate 18. The rotation of the knob 23 drives the rotating column 22 to rotate inside the first fixed plate 20 and the second fixed plate 21 at the same time. At the same time, it also drives the gear 24 and the eccentric wheel 25 to rotate. Since the sliding column 28 slides inside the limiting plate 29 and the fixed box 19, and the connecting frame 26 and the third fixed column 27 limit the sliding column 28, the eccentric wheel 25 causes the sliding column 28 to slide on the inner wall of the connecting frame 26 when rotating, and also slides inside the limiting plate 29 and the heating plate 30, so that the sliding column 28 slides out from the inside of the heating plate 30, and the heating plate 30 can be released from the fixed state. At this time, the heating plate 30 can be replaced. This method is simple and convenient, and can greatly improve the efficiency of replacing the heating plate 30.

[0032] Working principle: When the device needs to be used, it is only necessary to start the motor 3 inside the outer box 2. The motor 3 starts to drive the cylindrical rod 4 to rotate inside the drying box 1. The rotation of the cylindrical rod 4 drives the fixed ring 10 to rotate, and then drives the connecting bar 11 and the second fixed column 12 to rotate, so that the rotating wheel 13 rotates. When the rotating wheel 13 rotates, it presses the vibration bar 9 to move downward, so that the vibration bar 9 drives the first sliding column 6 and the first fixed column 8 to move downward, and then the vibration bar 9 presses the spring 7 to contract, and at the same time causes the first sliding column 6 to slide inside the bottom plate 5. Since the drying box 16 is fixedly connected to the vibration bar 9, When the vibration bar 9 moves downward, it also drives the drying box 16 to move downward. When the drying box 16 moves downward, it drives the second slide column 15 to slide on the inner wall of the slide cylinder 14. When the rotating wheel 13 rotates and passes the outer wall of the vibration bar 9, the vibration bar 9 is no longer subjected to external pressure. At this time, the spring 7 rebounds and pushes the vibration bar 9 to move upward, thereby causing the first slide column 6 to move upward and slide inside the bottom plate 5 again. The upward movement of the vibration bar 9 prompts the drying box 16 to move upward, thereby achieving the effect of preventing the particles from forming accumulation and agglomeration inside the drying box 1 through continuous vibration, and improving the drying efficiency of the plastic particles. The knob 23 is rotated to drive the rotating column 22 to rotate inside the first fixed plate 20 and the second fixed plate 21 at the same time. At the same time, the gear 24 and the eccentric wheel 25 are also driven to rotate. Since the sliding column 28 slides inside the limiting plate 29 and the fixed box 19, and the connecting frame 26 and the third fixed column 27 limit the sliding column 28, the eccentric wheel 25 causes the sliding column 28 to slide on the inner wall of the connecting frame 26 and also slide inside the limiting plate 29 and the heating plate 30 when rotating, so that the sliding column 28 slides out from the inside of the heating plate 30, and the heating plate 30 can be detached. The device is in a fixed state, so that according to different drying requirements or the characteristics of the plastic material, a suitable heating plate 30 can be selected for replacement, thereby ensuring the drying effect and quality, and providing greater flexibility and reliability. The device can not only prevent the particles from forming accumulation and agglomeration inside the drying box 1 through continuous vibration, thereby improving the drying efficiency of the plastic particles, but also can achieve the effect that according to different drying requirements or the characteristics of the plastic material, a suitable heating plate 30 can be selected for replacement, thereby ensuring the drying effect and quality, and providing greater flexibility and reliability.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
