[0030] The bottom end of the first spring 34 is fixedly connected to the inner wall bottom of the fixed frame 31, and the top end of the first spring 34 is fixedly connected to the bottom of the lifting frame.

[0031] The top end of the damping rod 35 is fixedly connected to the bottom of the lifting frame, and the top of the fixed seat 37 is fixedly connected to the bottom of the oil press body 5.

[0032] The oil press body 5 is located inside the soundproof cover 2.

[0033] Embodiment two

[0034] Please refer to Figures 4-5And on the basis of embodiment one, further get support mechanism 4.

[0035] Support mechanism 4 includes fixed plate 41, fixed plate 41 is connected to the top of the base 1, two fixed plate 41 between the front and back symmetrical fixed connection has a second guide rod 42, two second guide rod 42 surface symmetrical sliding connection has a first hinged frame 43, two second guide rod 42 surface between the fixed plate 41 and the first hinged frame 43 sleeve joint has a second spring 44, the first hinged frame 43 hinged has a hinge rod 45, the other end of the hinge rod 45 hinged has a second hinged frame 46.

[0036] Second spring 44 one end fixedly connected to the fixed plate 41 one side, the other end of the second spring 44 fixedly connected to the first hinged frame 43 close to the fixed plate 41 one side.

[0037] Second hinged frame 46 top fixedly connected to the bottom of the fixed seat 37.

[0038] In actual operation, when the device is in use, when the oil press body 5 starts to work, it will continuously produce a large working noise. At this time, the soundproof cover 2 arranged on the top of the base 1 and completely wrapped in the oil press body 5 plays a key role. The soundproof cover 2 is made of materials with good sound insulation performance, which can effectively block the noise generated by the oil press body 5 from spreading outside, limit the noise in the soundproof cover 2, thereby reducing the noise intensity that the operating personnel in the working environment are exposed to, creating a relatively quiet working environment for the operating personnel, reducing the interference and harm of noise to the human body, and buffering the mechanism 3. The front and rear and left and right of the fixed frame 31 are fixed on the top of the base 1, providing a stable support foundation for the entire buffering structure. During the working process of the oil press body 5, due to the reciprocating motion of the internal piston, hydraulic impact and other factors, vertical vibration will be generated. These vibrations are transmitted to the lifting frame through the fixing seat 37 and the supporting rod 36. The lifting frame slides up and down on the surface of the first guide rod 32. At this time, the first spring 34 sleeved on the surface of the first guide rod 32 and located between the inner wall bottom of the fixed frame 31 and the top of the lifting frame begins to work. When the lifting frame is subjected to downward force and moves downward, the first spring 34 is compressed, generating elastic restoring force, trying to push the lifting frame back to the original position, thereby absorbing and consuming part of the vibration energy, reducing the amplitude and frequency of vibration. At the same time, the damping rod 35 fixed on the inner wall bottom of the fixed frame 31 is connected to the bottom of the lifting frame at the top end. During the movement of the lifting frame, the damping medium in the damping rod 35 will hinder the movement of the lifting frame, further inhibit the vibration, convert the vibration energy into heat energy and other forms of energy, greatly reduce the noise generated by the vertical vibration, and also reduce the damage of the vibration to the oil press body 5 and the base 1 and other components, prolong the service life of the equipment. In the supporting mechanism 4, the fixed plate 41 is symmetrically connected to the top of the base 1, providing fixed support for the entire supporting structure. The second guide rod 42 fixedly connected between the two fixed plates 41 is symmetrically fixed in front and back, providing a track for the sliding of the first hinged frame 43. When the oil press body 5 generates vertical vibration, these forces and vibrations will be transmitted to the hinged rod 45 through the fixing seat 37 and the second hinged frame 46, and then drive the first hinged frame 43 to slide left and right on the surface of the second guide rod 42. At this time, the second spring 44 sleeved on the surface of the second guide rod 42 and located between the fixed plate 41 and the first hinged frame 43 begins to work. When the first hinged frame 43 is subjected to force in the direction of the fixed plate 41 and slides, the second spring 44 is compressed, generating elastic restoring force, trying to push the first hinged frame 43 back to the original position, thereby absorbing and consuming part of the horizontal force and vibration energy, reducing the amplitude and frequency of horizontal vibration, and ensuring the stability of the oil press body 5 in the horizontal direction.Meanwhile, the hinged structure of the hinged rod 45 between the first hinged frame 43 and the second hinged frame 46 can flexibly adjust and disperse the force, further balance the force received by the oil press body 5, make the whole supporting mechanism 4 better adapt to various changes of the oil press body 5 in the horizontal direction, reduce the noise and vibration caused by the instability in the horizontal direction, and improve the stability and reliability of the oil press work.

Moreover, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus.
