Example 1:

as shown in fig. 1 and 2, a food processing machine comprises a cup body 01, a tool apron 04 and a cutter shaft 03, wherein the tool apron 04 is arranged at the bottom of the cup body 01, the tool apron 04 is provided with a mounting hole 41 for mounting a bearing 05, one end of the cutter shaft 03 is in transmission connection with a motor, the other end of the cutter shaft passes through the bearing 05 and extends into the cup body 01 and is connected with a crushing cutter 06, a damping pad 07 is sleeved on the outer side of the bearing 05, the damping pad 07 is positioned between the outer side surface of the bearing 05 and the hole wall of the mounting hole 41, the damping pad 07 at least comprises two sub damping pads with different shore hardness, and each sub damping pad is sleeved on the cutter shaft 03 layer by layer from inside to outside in the radial. In the embodiment shown in fig. 1, the heating plate and the tool holder are integrated.

A vibration damping pad 07 is arranged between the bearing 05 of the cutter shaft 03 and the mounting hole 41 of the tool apron 04, and the vibration damping pad 07 is sleeved on the outer side of the cutter shaft bearing to absorb vibration generated when the cutter shaft works. The vibration reduction pad comprises a plurality of sub vibration reduction pads which are sleeved layer by layer along the radial direction of the cutter shaft and from the outer side of the bearing to the wall of the mounting hole, and each sub vibration reduction pad has different Shore hardness, namely each sub vibration reduction pad is formed by elastic materials with different hardness respectively so as to be suitable for deflection of different degrees caused in the working process of the cutter shaft. The damping pad at least comprises two sub damping pads with different shore hardness, for example, the damping pad can be set to a form comprising two, three, four or more sub damping pads, and specifically, the number of the sub damping pads can be set according to actual damping requirements.

The cutter shaft 03 can generate deflection of different degrees under the conditions of different rotating speeds or different loads. When the rotating speed of the cutter shaft 03 is low or the load is small, the deflection generated by the vibration of the cutter shaft 03 is small, the cutter shaft 03 transmits the vibration to the bearing 05, and the bearing 05 transmits the vibration to the vibration damping pad 07. The sub vibration-damping pad with the lower hardness of the vibration-damping pad 07 absorbs vibration to generate a larger deformation amount, the sub vibration-damping pad with the higher hardness absorbs vibration or absorbs vibration to generate a smaller deformation amount, at the moment, the sub vibration-damping pad with the lower hardness plays a main vibration-damping role, and the sub vibration-damping pad with the higher hardness can also play a role in limiting swing of the cutter shaft bearing and the sub vibration-damping pad with the lower hardness, so that noise generated by swing of the cutter shaft is further reduced, and the vibration-damping and noise-reducing effects of the vibration-damping pad 07 are improved.

Because the high-hardness sub vibration-damping pad has higher hardness and smaller deformation amount, the swing amplitude of the cutter shaft 03 can be further limited, thereby further reducing the noise generated by the swing of the cutter shaft 03 and improving the vibration-damping and noise-reducing effects of the vibration-damping pad 07.

In addition, because the outer side of the cutter shaft bearing is sleeved with the sub-vibration damping pads wrapped with a plurality of different hardness, the sub-vibration damping pads with different hardness have different deformation, and the sub-vibration damping pads with different deformation can generate friction locally on the contact surface due to different deformation, so that the vibration energy is converted into heat, and the absorption of vibration is facilitated.

The vibration damping pad protrudes out of the mounting position of the bearing, so that the vibration or the deflection generated by uneven stress of the spring can be further limited, and the bearing is subjected to uniform elastic extrusion force. In order to enable the bearing to be subjected to more uniform elastic extrusion force, a spring washer is additionally arranged between the bearing and the spring, and the spring extrudes the bearing through the spring washer, so that the bearing is subjected to more uniform stress, and the vibration of the bearing is further reduced.

Example 2:

the present embodiment is basically the same as embodiment 1 in structure and principle, except that: in embodiment 1, in the radial direction of the cutter shaft 03, the sub vibration damping pads are sleeved together in a mode that the shore hardness is gradually increased;

in this embodiment, in the radial direction of the cutter shaft 03, the sub vibration damping pads are sleeved together in a manner that the shore hardness is gradually reduced.

Specifically, the damping pad 07 includes two sub damping pads of different hardness: first and second damping pads 71 and 72, and a first sub damping pad 71 positioned at an inner side has a hardness greater than that of a second sub damping pad 72 positioned at an outer side.

Under the condition of low speed or light load, the deflection of the cutter shaft is small, the cutter shaft transmits vibration to the bearing, and the bearing transmits the vibration to the vibration damping pad. Because the first sub-vibration damping pad 71 has higher hardness, the first sub-vibration damping pad 71 can absorb the swing of the cutter shaft in a larger range, and within the elastic limit of the first sub-vibration damping pad 71, the first sub-vibration damping pad 71 plays a main vibration damping role, and meanwhile, the first sub-vibration damping pad 71 has higher hardness and can also play a limiting role on the cutter shaft, so that the swing of the cutter shaft is further reduced.

When the rotating speed is high or the load is large, the vibration of the cutter shaft is severe, at the moment, the deflection amount of the bearing exceeds the elastic limit of the first sub vibration damping pad 71, the first sub vibration damping pad 71 can generate certain amplitude of swing to transmit the vibration to the second sub vibration damping pad 72, and the second sub vibration damping pad plays a vibration damping role to absorb the vibration of the cutter shaft bearing and the first sub vibration damping pad 71. Meanwhile, the first sub-vibration damping pad 71 and the second sub-vibration damping pad 72 locally generate friction on the contact surface of the first sub-vibration damping pad and the second sub-vibration damping pad due to different deformation, so that vibration energy is converted into heat, vibration is attenuated, vibration generated by the swing of the cutter shaft is further reduced, and the vibration damping and noise reduction effects of the multistage vibration damping structure are improved.
