[0035] Reference Figure 6 The hydraulic press 2 is provided with a heat dissipation device 21 on its outer side. The heat dissipation device 21 includes a protective shell 22 and an aluminum plate 23. An exhaust fan 24 is provided inside the protective shell 22. An installation cylinder 25 is provided on one side of the protective shell 22. A drive motor 26 is provided inside the installation cylinder 25. A fan blade 27 is provided on the output shaft of the drive motor 26. A mesh plate 28 is provided on the side of the drive motor 26 away from the fan blade 27.

[0036] Reference Figure 2 and Figure 6 The aluminum plate 23 is fixedly connected to the outside of the hydraulic press 2, the exhaust fan 24 is fixedly connected to the top of the protective shell 22, the drive motor 26 and the mesh plate 28 are both fixedly connected to the inside of the mounting cylinder 25, and the protective shell 22 is snapped onto the top of the support plate 3. In this embodiment, the drive motor 26 drives the fan blades to rotate, and the protective shell 22 controls the airflow direction.

[0037] Reference Figure 1 and Figure 7 The feed cylinder 1 is provided with a connecting frame 31, and the connecting frame 31 is provided with a crushing roller 32.

The connecting frame 31 is fixedly connected to the connecting shaft 18, the baffle 33 is fixedly connected to the top of the connecting frame 31, and the crushing roller 32 is rotatably connected to the inside of the connecting frame 31. In this embodiment, the baffle 33 is used to facilitate the addition of materials, and the crushing roller 32 is used to facilitate the crushing of materials.

[0038] The implementation principle of this embodiment is as follows:

[0039] When the hydraulic press 2 needs to be repaired, first use tools to remove the fixing bolt 30, remove the protective shell 22 from the top of the support plate 3, then remove the limiting bolt 20 from the inside of the threaded hole 19, and press down to lift and lower. The lifting plate 9 slides inside the mounting frame 7 until the ball spring lock 8 engages with the inside of the ball groove 12 to fix the lifting plate 9. At this time, the support spring 11 is in a compressed state, and as the lifting plate 9 moves downward, the positioning block 13 is gradually pulled out from the inside of the positioning hole 15. After the connecting plate 10 is no longer restricted by the limiting block, the staff can push the hydraulic press 2 to slide. During the sliding of the hydraulic press 2, the guide block 5 will slide inside the limiting frame 6. The limiting frame 6 plays a limiting role. At the same time, the output shaft and the connecting shaft 18 of the hydraulic press 2 are no longer fixed by the limiting bolt 20. During the movement of the hydraulic press 2, the mounting block 16 will gradually be misaligned with the connecting shaft 18. Thus, the disassembly and assembly of the hydraulic press 2 are completed.

[0040] When the hydraulic press 2 needs to be installed, first, the guide block 5 is snapped into the inside of the limit frame 6, and the hydraulic press 2 is pushed to move until the guide block 5 can no longer move. Then, the lifting plate 9 is pushed upward, so that the ball spring lock 8 is disconnected from the ball groove 12. The support spring 11 will quickly restore its deformation and drive the lifting plate 9 to move upward. At the same time, the positioning block 13 is inserted into the inside of the positioning hole 15. The positioning block 13, the positioning hole 15 and the connecting plate 10 are used to fix the hydraulic press 2 and prevent the hydraulic press 2 from moving. At this time, the threaded hole 19 and the through hole 17 are concentric. Then, the limit bolt 20 is installed into the inside of the threaded hole 19. During the installation of the fixing bolt 30, the fixing bolt 30 will pass through the through hole 17 and play a limiting role. Finally, the fixing bolt 30 is used to install the protective shell 22 onto the top of the support plate 3.

[0041] During the operation of the hydraulic press 2, the drive motor 26 and the exhaust fan 24 start working simultaneously. The drive motor 26 drives the fan blades 27 to rotate, drawing air into the protective casing 22. Subsequently, the air flows over the outside of the aluminum plate 23, cooling the hydraulic press 2. After passing over the aluminum plate 23, the air temperature rises, and the exhaust fan 24 then draws the air out of the protective casing 22 to prevent the hydraulic press 2 from overheating, thereby extending its service life.

[0042] Compared with the prior art, the present invention has the following advantages:

[0043] The guide block 5 and the limit frame 6 work together to facilitate the sliding of the hydraulic press 2. The ball spring lock 8 and the ball groove 12 work together to facilitate the fixing of the lifting plate 9. The addition of the support spring 11 facilitates the resetting of the lifting plate 9. The positioning block 13, the mounting plate 14 and the positioning hole 15 work together to facilitate the fixing of the hydraulic press 2. By using the above structure, the hydraulic press 2 can be quickly assembled and disassembled, thereby improving work efficiency and reducing physical exertion. The addition of the aluminum plate 23 serves to conduct heat. The addition of the exhaust fan 24 promotes airflow. The addition of the mesh plate 28 provides dust protection. The work of the drive motor 26 and the fan blade 27 promotes airflow. The work of the fixing plate 29 and the fixing bolt 30 facilitates the fixing of the protective shell 22. By using the above structure, the temperature of the hydraulic press 2 can be effectively reduced, thereby extending its service life.

Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
