[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a cooling device for plastic product manufacturing, comprising a pipe, and further comprising: an air-cooling section installed on the inner wall of the pipe; a dustproof section installed on the pipe; a quick-change section installed at the top of the pipe; the dustproof section includes two hinge components arranged mirror-image inside the pipe; and a sliding component installed on the pipe; each hinge component includes a rotating shaft installed on the pipe, with a hinged dustproof plate one fixedly connected to the outer wall of the rotating shaft, and a hinged dustproof plate two located to the right of the first hinged dustproof plate, with a hinge shaft passing through the second hinged dustproof plate, and a gear fixedly connected to the outer wall of the hinge shaft; the front side of the rotating shaft of the hinge component located on the left extends rotatably to the outside of the pipe, and the hinge shaft is fixedly connected to the second hinged dustproof plate; the gears of the two hinge components mesh with each other; the hinge components, through the rotating shaft, the first hinged dustproof plate, the second hinged dustproof plate, and the meshing gears, realize the opening and closing of the pipe duct, providing dust protection for the internal components of the pipe.

[0006] Furthermore, the sliding assembly includes a motor fixedly connected to the front side of the pipe. The output shaft of the motor is fixedly connected to a rotating shaft located on the left side via a coupling. The outer wall of the hinge shaft is rotatably connected to two slotted sliders 1 on the outer wall of the hinge shaft. The outer wall of the rotating shaft located on the right side is rotatably connected to two sliders 2. The inner walls of the front and rear sides of the pipe are both provided with grooves. The two slotted sliders 1 are slidably connected to the inner walls of the two grooves respectively. The gear is located in the slotted slider 1 on the front side. The sliding assembly is powered by the motor. With the help of the sliding of the slotted sliders 1 and 2 in the grooves, the movement of the hinge assembly is driven and guided, ensuring that it stably completes the duct opening and closing action.

[0007] Furthermore, the air-cooling section includes a bracket fixedly connected to the inner wall of the pipe, and a fan is fixedly connected to the inner wall of the bracket; the fan is located below the first hinged dustproof plate and the second hinged dustproof plate.

[0008] Furthermore, the quick-change unit includes a protective component installed on the pipe; a snap-fit ​​component positioned above the pipe; the protective component includes several L-shaped blocks fixedly connected to the outer wall of the pipe; a protective mesh plate is provided at the top of the pipe; the outer wall of the protective mesh plate contacts the top of the pipe, and the outer wall of the protective mesh plate contacts the inner wall of the several L-shaped blocks; the protective component supports and positions the protective mesh plate through the L-shaped blocks, preventing large-volume materials from falling into the pipe and avoiding damage to core components such as the fan due to impact.

[0009] Furthermore, the buckle assembly includes a slide rod passing through the L-shaped block, the slide rod being slidably connected to the L-shaped block, a circular block being fixedly connected to the outer wall of the slide rod, an elastic element being provided on the rear side of the circular block, and the rear side of the slide rod extending into the protective mesh panel; the outer wall of the slide rod is in contact with the inner wall of the protective mesh panel, and the elastic element includes a spring fixedly connected to the rear side of the circular block; the rear side of the spring is fixedly connected to the L-shaped block. The buckle assembly utilizes the cooperation of the slide rod, the circular block, and the spring to achieve quick assembly and disassembly of the protective mesh panel, reducing maintenance difficulty and facilitating timely replacement of the protective mesh panel.

[0010] This utility model has the following beneficial effects: 1. By setting up a dustproof section, when opened, the hinge assembly uses a rotating shaft, hinge dustproof plate one, hinge dustproof plate two, and meshing gears to complete the deflection, folding, and resetting action of the dustproof plate; the sliding assembly uses a motor as a power source, and through the sliding of slotted slider one and slider two in the slot, it provides stable guidance and drive support for the movement of the hinge assembly. When the device stops running, the dustproof section can quickly close the duct air passage, effectively blocking dust and impurities from entering the inside of the duct, preventing them from adhering to the core components such as the fan, thereby ensuring the service life and operational stability of the fan, reducing equipment failures caused by dust accumulation, and ensuring that the cooling device can work normally and efficiently in the future. 2. By incorporating a quick-change section, the L-shaped block in the protective assembly provides stable support and positioning for the protective mesh panel. The protective mesh panel can prevent large objects such as stones and metal fragments from falling into the pipeline during operation, avoiding damage to the fan and further protecting the safety of the core components of the device. The snap-fit ​​assembly, through the cooperation of a sliding rod, a circular block, and a spring, enables quick installation and removal of the protective mesh panel—pulling the sliding rod releases the fixing of the protective mesh panel, and after release, the spring drives the sliding rod to reset and complete the fixing. No complicated tools are required, which greatly shortens the replacement time of the protective mesh panel, reduces the difficulty and cost of equipment maintenance, and ensures the continuous and stable operation of the cooling device.

The two slotted sliders 222 are slidably connected to the inner walls of the two grooves 224 respectively. Gear 215 is located in the slotted slider 222 on the front side. By setting the dustproof part 2, when the device stops running, the air duct of pipe 111 can be quickly closed, effectively blocking dust and impurities from entering the inside of the pipe and preventing them from adhering to the core components such as fan 113, thereby ensuring the service life and operational stability of fan 113 and ensuring that the cooling device can work normally and efficiently in the future.

[0018] The quick-change unit 3 includes a protective assembly 31, which is mounted on the pipe 111; and a snap-fit ​​assembly 32, which is positioned above the pipe 111. The protective assembly 31 includes several L-shaped blocks 311 fixedly connected to the outer wall of the pipe 111. A protective mesh plate 312 is provided at the top of the pipe 111. The outer wall of the protective mesh plate 312 contacts the top of the pipe 111 and the inner wall of the several L-shaped blocks 311. The snap-fit ​​assembly 32 includes a sliding rod 321 passing through the L-shaped blocks 311, and the sliding rod 321 is slidably connected to the L-shaped blocks 311. A circular block 322 is fixedly connected to the outer wall of the slide rod 321. An elastic element is provided on the rear side of the circular block 322. The rear side of the slide rod 321 extends into the protective mesh plate 312. The outer wall of the slide rod 321 contacts the inner wall of the protective mesh plate 312. The elastic element includes a spring 323 fixedly connected to the rear side of the circular block 322. The rear side of the spring 323 is fixedly connected to the L-shaped block 311. By setting the quick replacement part 3, the protective mesh plate 312 can be disassembled and installed without complicated tools, which greatly shortens the replacement time of the protective mesh plate 312, reduces the difficulty and cost of equipment maintenance, and ensures the continuous and stable operation of the cooling device.

[0019] It should be noted that the control of the fan 113 and the motor 221 in this application can both be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be implemented using existing technologies, such as PLC.

[0020] A specific application of this embodiment is as follows: In use, the pipe 111 is installed on the top of the cooling tower for plastic product production to assist the cooling tower in cooling down. The fan 113 on the bracket 112 is turned on. The fan 113 drives the airflow to enter from the bottom of the cooling tower, and then exits through the pipe 111, thereby taking away the heat of cooling and cooling it. Before use, the motor 221 is started to analyze the hinge assembly 21 on the left side. The motor 221 drives the hinge dustproof plate 1 212 to rotate downward around the rotating shaft 211, thereby the hinge dustproof plate 1 212 drives the hinge dustproof plate 213 to rotate. The hinged dustproof plate 213 drives the hinge shaft 214 to rotate while pulling it to the left. This causes the hinge shaft 214 to drive the gear 215 to rotate, simultaneously causing the front slotted slider 222 to slide to the left within the front slot 224. At this time, the left gear 215 drives the right gear 215 to rotate, causing the right hinge assembly 21 to perform a mirror-image motion similar to the left hinge assembly 21. This causes the hinged dustproof plates 212 and 213 of both hinge assemblies 21 to deflect and fold, opening the duct 111. Conversely, the motor 221 reverses direction, using the opposite process to reset the two hinge assemblies 21, closing the duct 111. This allows for the cleaning of the duct 111 within the duct itself when the device stops operating. The protective mesh plate 312 protects against dust and impurities from entering and affecting the lifespan of the fan 113. It also prevents large objects such as stones and metal fragments from falling into the pipe 111 and damaging the fan 113 during operation. To replace the protective mesh plate 312, pull the rotating shaft 211 forward, causing the circular block 322 to move forward. As the circular block 322 moves forward, the spring 323 is stretched until the sliding rod 321 separates from the protective mesh plate 312. Then, the protective mesh plate 312 can be removed. After inserting the new protective mesh plate 312 back into its original position, release the sliding rod 321. The spring 323, through the circular block 322, causes the sliding rod 321 to reset and insert onto the new protective mesh plate 312, thus fixing the protective mesh plate 312 onto the pipe 111, completing the replacement of the protective mesh plate 312.
