[0036] The technical content of the present application will be described in detail below in combination with the drawings and specific embodiments.

[0037] First Embodiment

[0038] As shown in the drawings, Figure 1 The first embodiment of the present application provides a banknote compression and adjustment mechanism, which comprises a rotating shaft 1, a rotating arm 2, a compression part 3, an adjustment part 4, and a driving part 5, and is used for adaptively compressing sheet materials to improve detection accuracy.

[0039] Among them, the rotating arm 2 can rotate around the axis of the rotating shaft 1. The compression part 3 is arranged on the rotating arm 2 to compress the banknote and can rotate with the rotation of the rotating arm 2, thereby forming a floating compression part 3 to adapt to the magnetic image detection of banknotes of different thicknesses. The adjustment part 4 is provided with a magnetic image sensor, and the specific position of the magnetic image sensor can be adjusted to cooperate with the detection head to detect the magnetic image of the banknote. The driving part 5 is connected with the compression part 3 to drive the compression part 3 to rotate, thereby driving the banknote to complete the magnetic image detection.

[0040] Specifically, in the present embodiment, as shown in Figure 1 the rotation shaft 1 is used to be mounted on the financial detection device 50, which can be an existing rotation shaft on the financial detection device, or a separate rotation shaft provided on the financial detection device. The rotation shaft 1 is used to provide a mounting basis for the rotating arm 2, and the structure of the rotation shaft 1 is not specifically limited herein.

[0041] As shown in Figure 2 the first end (i.e. the A end in Figure 2 ) of the rotating arm 2 is rotatably connected to the rotation shaft 1 around the axis of the rotation shaft 1, so that the second end (i.e. the B end in Figure 2 ) of the rotating arm 2 can rotate relative to the first end of the rotating arm 2 around the axis of the rotation shaft 1 (as shown by the rotation arrow in Figure 2 ). In the present embodiment, the length of the rotating arm 2 is selected according to the size specification of the bill to be detected and the distance from the working surface, so that the pressing part 3 can exert a preset pressure on the surface of the bill. Preferably, in an embodiment of the present application, the length of the rotating arm 2 (perpendicular to the axis of the rotation shaft 1) is adjustable, so that the length of the rotating arm 2 can be adaptively adjusted according to different use scenarios.

[0042] As shown in Figure 2 , the pressing part 3 is movably mounted on the second end of the rotating arm 2, and is used to press the bill 10 against the working surface 20. Specifically, in the present embodiment, the pressing part 3 is a pressing roller (preferably a double roller arranged in parallel), which is rotatably mounted on the second end of the rotating arm 2 and parallel to the rotation shaft 1 and the working surface 20, so that the rotation of the pressing roller drives the bill 10 to move on the working surface 20 to complete the magnetic image detection. It can be understood that, in the process of pressing the bill 10 by the pressing part 3, if there is a foreign object on the bill 10, when the pressing part 3 contacts the foreign object, the pressing part 3 will be lifted by the foreign object, causing the rotating arm 2 to rotate counterclockwise, until the foreign object passes through the pressing part 3, and then the pressing part 3 is pressed against the bill 10 again under the action of gravity. Thus, by using the floating pressing part 3, the gap can be automatically adjusted to avoid the risk of abnormal stop when the bill is mixed with foreign objects, and the position of the pressing part 3 can be automatically restored under the action of gravity to reduce abnormal detection and improve detection efficiency.

[0043] In the above embodiment, preferably, the pressing roller 3 is made of a non-metallic material, such as ceramic, glass, etc., so as to reduce the wear of the pressing roller and ensure the pressing effect on the bill.

[0044] In the above embodiment, preferably, at least one foreign matter groove 31 is formed on the pressing roller 3 in the circumferential direction, so as to provide a passage for the foreign matter when the foreign matter exists on the banknote, and to improve the convenience of the foreign matter passing through the pressing roller 3. More preferably, a plurality of foreign matter grooves 31 are formed on the pressing roller 3, the plurality of foreign matter grooves 31 are arranged at intervals along the length direction of the pressing roller 3, and the width and depth of each foreign matter groove 31 are different, so as to adapt to foreign matters of different sizes.

[0045] In the above embodiment, the adjusting part 4 is movably arranged on the rotating arm 2, so as to adjust the relative position between the rotating arm 2 and the working surface 20. The adjusting part 4 comprises a first adjusting assembly 41 and a second adjusting assembly 42, the first adjusting assembly 41 is used to adjust the left-right height of the rotating arm 2, and the second adjusting assembly 42 is used to adjust the front-rear height of the rotating arm 2, so as to ensure that the pressing roller 3 arranged on the rotating arm 2 is parallel to the working surface.

[0046] Specifically, in the present embodiment, referring to Figure 3 , the first adjusting assembly 41 comprises two first adjusting screws. Two first slot-shaped holes 201 are formed on the left and right sides of the front surface of the rotating arm 2 respectively, the first slot-shaped hole 201 is arranged in the vertical direction, and the first adjusting screw is movably arranged in the first slot-shaped hole 201. When it is necessary to adjust the position of the left and right sides of the rotating arm 2, the first adjusting screws on the left and right sides are loosened first, so that the left or right side of the rotating arm 2 can be adjusted in the vertical direction. When the height is determined, the first adjusting screws are tightened. Similarly, the second adjusting assembly 42 comprises two second adjusting screws, the two second adjusting screws are arranged on the side surface of the rotating arm 2 in the front-rear direction of the rotating arm 2, and are movably arranged in two second slot-shaped holes 202 respectively, so as to adjust the distance between the front and rear ends of the rotating arm 2 and the working surface 20 respectively.

[0047] As shown in Figure 1 , in the above embodiment, the driving part 5 comprises a driving roller 51, a motor (not shown in the figure) and a belt 52. The driving roller 51 is movably arranged on the rotating shaft 1; the motor, the power output shaft of the motor is connected with the driving roller 51, so as to drive the driving roller 51 to rotate; and the belt 53 is connected between the driving roller 51 and the pressing roller 3, so as to transmit power. Preferably, in the present embodiment, the motor has a plurality of gears, so that the rotating speed of the pressing roller 3 is different under different gears, so as to adapt to different magnetic image detection.

[0048] It can be understood that the specific structure of the above driving part 5 is only one of the more preferred embodiments, and in other embodiments, the driving part 5 can also be a motor directly installed on one side of the pressing roller 3, so as to directly drive the pressing roller 3 to rotate.

[0049] Second embodiment

[0050] As Figure 4 shown in the first embodiment, the second embodiment of the present application also provides a paper currency pressing adjusting mechanism, comprising a rotating shaft 1, a rotating arm 2, a pressing part 3, an adjusting part 4 and a driving part 5. Compared with the first embodiment, the difference of the present embodiment is that the rotating arm 2 can be quickly reset.

[0051] Specifically, in the present embodiment, the paper currency pressing adjusting mechanism further comprises a elastic band 6 and an auxiliary roller 7. The auxiliary roller 7 is arranged on one side of the driving roller 51, and the elastic band 6 is sequentially arranged on the driving roller 51, the pressing roller 3 and the auxiliary roller 7, thereby forming a triangle shape, so as to provide elastic force for the quick recovery of the rotating arm 2.

[0052] Therefore, when the rotating arm 2 rotates counterclockwise, the rotating arm 2 will be subjected to the gravity of itself and the elastic tension of the elastic band 6 at the same time, so that the rotating arm 2 can quickly recover to the original state, avoiding the influence of the slow reset of the rotating arm 2 on the detection efficiency of the paper currency.

[0053] In addition to the above structure, the rest of the structural features of the present embodiment are the same as those of the first embodiment, which will not be described here.

[0054] Third embodiment

[0055] On the basis of the first embodiment or the second embodiment, the third embodiment of the present application further provides a financial detection device, comprising the above-mentioned paper currency pressing adjusting mechanism.

[0056] In summary, the paper currency pressing adjusting mechanism and the financial detection device provided by the embodiments of the present application have the following beneficial effects:

[0057] 1. The pressing part 3 can rotate with the rotating arm 2, thereby adaptively adjusting the gap to avoid the risk of abnormal shutdown when the paper currency is mixed with foreign matter, and the position of the pressing part 3 can automatically recover to the original position under the action of gravity, thereby reducing abnormal detection and improving detection efficiency.

[0058] 2. The pressing part 3 is made of non-metallic material and high-hardness material, which can reduce wear and ensure the pressing effect on the paper currency.

[0059] 3. Different width and depth foreign matter grooves are formed on the pressing part 3 for foreign matter to pass through.

[0060] 4. The adjusting part 4 can adjust the position of the rotating arm 2, so that the pressing part 3 is parallel to the working surface, thereby ensuring the pressing effect on the paper currency.

[0061] 5. The setting of the elastic band 6 in cooperation with the auxiliary roller 7 can make the rotating arm 2 quickly reset, thereby avoiding the influence of the slow reset of the rotating arm 2 on the detection efficiency of the paper currency.
