The process of weighing gunpowder on the frame 100 is as follows: the powder filling device is driven to move by the driving device 300, powder is gradually filled into the powder cup, and the weighing device 400 is used for weighing the powder in the powder cup in real time.

It should be understood that the specific structure of the driving device 300, the powder loading device and the weighing device 400 and the connection manner thereof are well known to those skilled in the art, and will not be described in detail herein.

During the weighing process, vibration is generated due to the movement of the driving device 300, and the driving device 300 is disposed on the frame 100 together with the weighing device 400, and the vibration is transmitted to the frame 100 and transmitted to the weighing device 400 through the frame 100, so that the weighing device 400 affects the accuracy of the weighing due to the vibration.

Specifically, a first damping device 500 is arranged between the driving device 300 and the support plate 200 to reduce vibration during operation of the driving device 300, so as to achieve first attenuation of vibration, the vibration after the first attenuation is transmitted to the support plate 200, the vibration is transmitted to the rack 100 through the support plate 200, a second damping device 600 is arranged between the support plate 200 and the rack 100, a part of vibration is absorbed by the second damping device 600, so as to achieve second attenuation of vibration, the vibration after the second attenuation is transmitted to the weighing device 400 through the rack 100, a third damping device 700 is arranged between the rack 100 and the weighing device 400, a part of vibration is absorbed by the third damping device 700, so as to achieve third attenuation of vibration, so that the vibration received by the weighing device 400 is smaller, and thus weighing is more accurate.

It is worth understanding that the above embodiment has little modification to the existing equipment, and only needs to install the first damping device 500 between the driving device 300 and the supporting plate 200, the second damping device 600 between the supporting plate 200 and the rack 100, and the third damping device 700 between the rack 100 and the weighing device 400, so as to implement the modification of the equipment, and the required materials are also convenient to obtain, and at the same time, a better damping effect can be obtained, and the cost performance is very high.

Of course, in this embodiment, there may be two weighing devices 400, and after the first weighing of gunpowder is completed, the second weighing may be performed again, so that the weighing result of gunpowder is more accurate, and a separate third damping device 700 is disposed below each weighing device 400, so as to reduce the vibration of the weighing device 400 and improve the weighing precision.

In addition, also can place weighing device 400 through the solitary cabinet body, when weighing device 400 is placed alone, need customize alone the cabinet body, still need punch in current frame 100, the through-hole is settled to this hole, will be linked together with ground, the position of settling the through-hole is corresponding with weighing device 400's mounted position, finally, put into the cabinet body of customization and settle the through-hole, and realize weighing device 400 and frame 100's isolation, but this kind of mode, the equipment that needs to change is more, and the cost is higher, and be not convenient for carry out the rectification to current equipment.

Referring to fig. 1, fig. 3, fig. 4 and fig. 6, in some embodiments of the present invention, the first damping device 500, the second damping device 600 and the third damping device 700 are a plurality of damping members, the two ends of each damping member are respectively a damping surface and a vibration transmission surface, the damping surface is used for connecting to a vibration source, the vibration transmission surface is used for connecting to a damped member, the damping member includes N damping layers 810 and M partition boards 820, the N damping layers 810 and the M partition boards 820 are sequentially spaced from each other along the damping surface to the vibration transmission surface, each damping layer 810 is provided with damping grooves 811 with different amounts, and the amount of the damping grooves 811 of each layer of damping layers 810 is sequentially increased along the damping surface to the vibration transmission surface.

Specifically, shock-absorbing layer 810 and baffle 820 through mutual interval setting, make the energy of vibrations can carry out the loss in shock-absorbing layer 810 and baffle 820, in this embodiment, shock-absorbing layer 810 is the rubber pad, wherein, the ability that the rubber pad absorbed vibrations relies on the elastic deformation of self to realize, and cut apart into two little rubber pads with holistic rubber pad through shock-absorbing groove 811, make the shock attenuation space of two little rubbers bigger, in shock-absorbing layer 810 that shock-absorbing groove 811 is more, its vibrations are dispersion also more and more littleer, the quantity that contains shock-absorbing groove 811 through setting up every layer shock-absorbing layer 810 simultaneously increases progressively along inhaling the face of shake to the face direction of transfer in proper order, make shock-absorbing layer 810 of every layer, all will weaken vibrations, in order to reach the absorbing effect.

Therefore, the shock absorbing surface of the first shock absorbing device 500 is used for being connected with the driving device, the shock transmitting surface is used for being connected with the support plate 200, the shock absorbing surface of the second shock absorbing device 600 is used for being connected with the support plate 200, the shock transmitting surface is used for being connected with the rack 100, the shock absorbing surface of the third shock absorbing device 700 is used for being connected with the rack 100, and the shock transmitting surface is used for being connected with the weighing device 400.
