[0022] See also Figure 1-4 , the utility model provides a technical solution:

[0023] In the present technical solution, a low-noise banknote counter banknote pressing wheel includes a banknote counter bracket 1, a banknote pressing shaft 3 is installed between the banknote counter bracket 1, and a banknote pressing wheel body 2 is installed at both ends of the outer side of the banknote pressing shaft 3; a driving cavity 7 is opened on the inner wall of the banknote counter bracket 1, a driving block 5 is installed inside the driving cavity 7, a bearing is installed on the side wall of the driving block 5, and the end of the banknote pressing shaft 3 is installed in the bearing; the upper ends of the driving block 5 are located between the driving cavity 7 and are equipped with a noise reduction component 6, the noise reduction component 6 includes an arched buffer plate 61, both ends of the arched buffer plate 61 are connected to the inner wall of the driving cavity 7, a noise reduction pad 65 is installed at the high point of the arched buffer plate 61, and the noise reduction pad 65 is connected to the driving block 5.

[0024] In this technical solution, the money counter bracket 4 is a bracket for mounting the money pressing shaft 3 in the money counter in the prior art. The money pressing shaft 3 and the money pressing wheel body 2 are both components in the money counter. The specific structure and working principle are not described in detail in this case. The driving block 5 is fixed in the driving cavity 7. The noise generated between the driving block 5 and the money counter bracket 1 is eliminated by the noise reduction component 6. The buffering is achieved by the elasticity and shape of the arched buffer plate 61, and the noise is reduced by the noise reduction pad 65.

[0025] In some technical solutions, shock absorbers 62 are installed on the side walls of both ends of the arched buffer plate 61 , and an adaptation mechanism 64 is installed on the end of the shock absorber 62 , and the end of the adaptation mechanism 64 is connected to the driving block 5 .

[0026] In this technical solution, buffering is performed through the cooperation of the shock absorber 62 and the adaptation mechanism 64 .

[0027] In some technical solutions, the adaptation mechanism 64 includes an outer plate 644, a middle plate 643 and an inner plate 641. The four corners of the outer plate 644 and the middle plate 643 are hinged to each other, and the four corners of the other side of the middle plate 643 are hinged with telescopic rods 642; the other ends of the four telescopic rods 642 are hinged to the four corners of one side of the inner plate 641.

[0028] In this technical solution, the three plates are hinged to each other to bear forces in all directions.

[0029] In some technical solutions, a rubber pad 63 is installed at the end of the outer plate 644, and the rubber pad 63 is connected to the outer wall of the driving block 5;

[0030] In this technical solution, the friction force of the outer plate 644 can be increased by providing the rubber pad 63 .

[0031] In some technical solutions, the noise reduction cushion layer 65 includes a metal mesh support 653, which serves as a framework. A sound insulation layer made of flame-retardant material is formed on both sides of the metal mesh support 653. A biodegradable material is pre-placed on the side close to the metal mesh support 653. The sound insulation layer has a plurality of sound-absorbing strip holes 652 formed on the side close to the metal mesh support 653. Inert gas is introduced on the side away from the metal mesh support 653. A plurality of oscillation holes 651 of different sizes are formed inside the sound insulation layer on the side away from the metal mesh support 653.

[0032] In this technical solution, during the molding process of the sound insulation layer, a degradable material is pre-positioned on the side close to the metal mesh bracket 653 so that the sound insulation layer forms a plurality of silencer strip holes 652 on the side close to the metal mesh bracket 653. During the molding process of the sound insulation layer, an inert gas is introduced on the side away from the metal mesh bracket 653 so that a plurality of oscillation holes 651 of different sizes are formed inside the sound insulation layer on the side away from the metal mesh bracket 33; the metal mesh bracket 653 serves as a skeleton (compared with metal plates, it is easier for flame retardant materials to be used as a bracket for molding); specifically, the metal mesh bracket 653 can extend a plurality of slender metal needles to both sides. The role of the metal needles is, on the one hand, to increase the molding contact area of ​​the flame retardant material and improve the firmness of the connection between the flame retardant material and the skeleton; on the other hand, the metal needles can absorb energy (sound) by themselves through energy transfer, and through the advantage of their high rigidity (the characteristics of their own material and connection to the skeleton), they use ultra-low frequency vibration to quickly consume energy; on this basis, firstly, by Inert gas is introduced into the side away from the metal mesh bracket 653 to form a number of oscillation holes 651 of different sizes inside the sound insulation layer on the side away from the metal mesh bracket 33. The oscillation holes 651 can make the sound oscillate back and forth in a spherical space of varying sizes, changing its sound frequency, thereby converting noise of similar frequencies into noise with a larger frequency difference, preventing the resonance and superposition of sounds; on the side close to the metal mesh bracket 653, a degradable material is pre-positioned to form a number of silencer strip holes 652 in the sound insulation layer on the side close to the metal mesh bracket 653; the degradable material can be removed after the sound insulation layer is formed by high temperature, solution treatment, etc., and the correspondingly formed silencer strip holes 652 can use the slender gaps to filter out part of the noise (especially high-frequency short waves).

[0033] In some technical solutions, stabilizing plates 4 are installed at both ends of the outer side of the banknote pressing shaft 3;
