The overall idea is as follows:

[0027] To address the problems existing in the prior art, this utility model provides a drying device for processing plastic products. This drying device includes a material hopper 20, with a connecting pipe 1 fixedly connected to the outside of the hopper 20. A control box 2 is fixedly installed outside the connecting pipe 1. A protective mechanism is provided outside the control box 2, including a protective cover 3, a rotating shaft 4, an observation plate 5, a protective plate 6, a threaded rod 7, a threaded sleeve 8, a groove 9, and a limiting groove 10. The protective cover 3 is located outside the control box 2. The rotating shaft 4 is rotatably connected to the outside of the protective cover 3. The observation plate 5 is fixedly connected to the outside of the rotating shaft 4. The protective plate 6 is slidably connected to the side of the protective cover 3 near the observation plate 5. The threaded rod 7 is fixedly installed at the end of the observation plate 5 away from the rotating shaft 4. The threaded sleeve 8 is threadedly connected to the outside of the threaded rod 7. The groove 9 is located at the end of the protective cover 3 away from the rotating shaft 4. The limiting groove 10 is located at the side of the protective cover 3 near the groove 9. The groove 9 is connected to the limiting groove 10. The threaded rod 7 is movably connected inside the groove 9, and the threaded sleeve 8 is movably connected inside the limiting groove 10. By setting up the observation plate 5, in conjunction with the threaded rod 7, when the operator needs to operate the control box 2, the threaded sleeve 8 is rotated to disengage the threaded sleeve 8 from the limiting groove 10. Then, the threaded sleeve 8 is rotated upward to move away from the protective cover 3. At this time, the observation plate 5 is rotated downward to expose the control box 2. After the operator has finished operating the control box 2, the observation plate 5 is rotated upward to allow the threaded rod 7 to enter the groove 9. Then, the threaded sleeve 8 is rotated downward to move the threaded sleeve 8 into the limiting groove 10. At this time, the observation plate 5 is installed. The observation plate 5 provides protection for the external switch of the control box 2, reducing the probability of damage from collisions with other objects, and preventing the switch button from being accidentally touched, thus providing a guarantee for the normal operation of the device.

[0028] The protective cover 3 is externally fixedly connected to two first springs 11. Both first springs 11 are fixedly connected to the outside of the protective plate 6 to facilitate the support of the protective plate 6. An outer cover plate 12 is fixedly installed on the outside of the protective cover 3. The first springs 11 are located on the inner side of the outer cover plate 12 to provide protection for the first springs 11. Sliding grooves 13 are opened at both ends of the inner side of the outer cover plate 12. The two ends of the protective plate 6 are respectively slidably connected to the inside of the two sliding grooves 13 to prevent the connection between the protective plate 6 and the inner side of the outer cover plate 12 from being disconnected.

[0029] Both ends of the control box 2 are provided with mounting slots 14. The protective cover 3 is respectively snapped into the two mounting slots 14 at both ends for easy disassembly and assembly. Both ends of the control box 2 are provided with moving slots 15. Each moving slot 15 has a limiting plate 16 slidably connected inside. The limiting plate 16 fits against the inside of the mounting slot 14 to limit the movement of the protective cover 3. A second spring 17 is fixedly connected inside each moving slot 15. The limiting plate 16 is fixedly connected to the outside of the second spring 17 to provide support for the limiting plate 16. Each moving slot 15 has an internal slot 18. Each internal slot 18 has an internal slot slidably connected to an internal slot. Plate 19, the built-in plate 19 is fixedly installed on the outside of the limiting plate 16 to prevent the connection between the limiting plate 16 and the moving groove 15 from being disengaged. By setting the mounting groove 14, and cooperating with the limiting plate 16, the protective cover 3 is aligned with the mounting groove 14. At this time, the limiting plate 16 is pressed to make the limiting plate 16 enter the interior of the moving groove 15. At this time, the protective cover 3 is pushed so that both ends of the protective cover 3 enter the interior of the mounting groove 14 until one end of the limiting plate 16 passes through the mounting groove 14. At this time, the limiting plate 16 is released. Under the action of the spring, the limiting plate 16 moves to the outside of the moving groove 15. At this time, the protective cover 3 is installed. The installation steps of the protective cover 3 are simple, reducing the error rate of the installation process and improving the installation efficiency.

[0030] Working principle:

[0031] First, align the protective cover 3 with the mounting groove 14. Then, press the limiting plate 16 to make it enter the interior of the moving groove 15. Next, push the protective cover 3 so that both ends of the protective cover 3 enter the interior of the mounting groove 14 until one end of the limiting plate 16 passes through the mounting groove 14. Then, release the limiting plate 16. Under the action of the spring, the limiting plate 16 moves to the outside of the moving groove 15. At this point, the protective cover 3 is installed. Then, rotate the observation plate 5 upward to make the threaded rod 7 enter the interior of the groove 9. Then, rotate the threaded sleeve 8 to move the threaded sleeve 8 downward until the threaded sleeve 8 enters the interior of the limiting groove 10. At this point, the observation plate 5 is installed.

[0032] The second step involves the operator rotating the threaded sleeve 8 to disengage it from the limiting groove 10. The threaded sleeve 8 is then rotated upwards to move away from the protective cover 3. The observation plate 5 is then rotated downwards to expose the control box 2, allowing the operator to operate it. After operation, the observation plate 5 is rotated upwards to allow the threaded rod 7 to enter the groove 9. The threaded sleeve 8 is then rotated downwards until it enters the limiting groove 10, completing the installation of the observation plate 5. The observation plate 5 is made of transparent material, allowing the operator to observe the control box 2. When the operator needs to operate a knob on one side of the control box 2, the protective plate 6 is pushed into the inner side of the outer cover 12, exposing the knob. The operator can then operate it. After operation, the protective plate 6 is released, and under the action of the first spring 11, it moves to cover the knob.

[0033] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
