[0028] Referring to Figure 2 and Figure 3 , the inner wheel 201 in the pressure wheel mechanism 2 is clamped on the installation part 101 through the action of the ball head plunger 102 and the positioning guide hole 208, the ball head plunger 102 and the positioning guide hole 208 play a positioning role when the pressure wheel mechanism 2 is installed, because the quality of banknotes is very small, so the ball head plunger 102 basically does not need to bear any lateral load during the operation of the device, so the pressure wheel mechanism 2 will not be dislocated during normal operation of the device;
[0029] The outer side of the inner wheel 201 is integrally formed with a fixing piece 204, the other end of the fixing piece 204 and the outer wheel 202 are integrally formed, the fixing piece 204 is an arc structure, and the fixing piece 204 is provided with twenty-four groups, and the fixing pieces 204 are arranged in an annular array, and the fixing pieces 204 form a heat dissipation groove one, which can help the inner wheel 201 to dissipate a small amount of heat generated during long-time operation;
