Description

Technical Field

[0001] The utility model relates to the technical field of banknote counter accessories, in particular to a resistance wheel of a banknote counter. Background Art

[0002] The resistance wheel (often also called the twisting wheel or twisting rubber ring) in the banknote counter is a key component that enables the banknote counter to accurately feed each banknote into the banknote verification mechanism.

[0003] The resistance wheel is made of rubber and has many ridges or grooves on its periphery. These designs are mainly to increase the friction between the wheel and the banknotes, ensuring that the banknotes can be twisted out stably and accurately during transportation. When the banknotes are fed into the banknote counter, the resistance wheel starts to rotate and generates friction with the banknotes through the ridges or grooves on its periphery. This friction allows the banknotes to be twisted out one by one, rather than multiple banknotes at once or sticking together.

[0004] The current resistance wheel structure is fixed to a rubber ring and a clamping seat. Since the rubber resistance wheel is easily damaged, and multiple sets of resistance wheels are mounted on the support rod for installing the resistance wheel, the support rod and the resistance wheel need to be completely disassembled, which makes replacement inconvenient and inefficient. Therefore, we propose a resistance wheel for a money counter. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art. The current resistance wheel structure is fixed to a rubber ring and a clamping seat. Since the resistance wheel made of rubber material is easily damaged, and multiple groups of resistance wheels are provided on the support rod for installing the resistance wheel, the support rod and the resistance wheel need to be completely disassembled, which makes replacement inconvenient and inefficient.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A resistance wheel for a banknote counter comprises a resistance ring and a wheel body, wherein the wheel body is composed of three sections, a snap-fit ​​sleeve is connected to the periphery of the middle section of the wheel body, and resistance rings are sleeved on the peripheries of the two sections of the wheel body at both ends of the middle section of the wheel body. A surrounding embedded groove is provided on the inner side of the resistance ring, and a snap-fit ​​ring is provided around the periphery of the wheel body corresponding to the embedded groove. Annular notches are provided at both ends of the wheel body near the periphery, and positioning plates are threadedly connected to the annular notches.

[0008] Furthermore, the clamping sleeve includes an upper clamping sleeve and a lower clamping sleeve, both of which have semicircular cross-sections. The corresponding ends of the upper clamping sleeve and the lower clamping sleeve are respectively provided with a clamping block and a clamping groove. The outer side of the clamping block is provided with a clamping strip along the length direction, and the corresponding clamping strip is clamped with a clamping slot in the clamping groove.

[0009] Furthermore, the cross section of the embedded groove is convex.

[0010] Furthermore, the cross section of the clamping ring is convex, and the resistance ring is installed by clamping the convex clamping ring into the convex embedded groove.

[0011] Furthermore, the wheel body is fixedly mounted on the resistance wheel support rod.

[0012] Furthermore, an external thread is provided on the inner circular wall of the annular notch.

[0013] Furthermore, the positioning plate is provided with a docking ring at the end corresponding to the annular groove, and an internal thread is provided on the periphery of the docking ring. The outer diameter of the positioning plate is larger than the wheel body, and the positioning plate is completely inserted into the annular groove through the docking ring. At the same time, the external thread and the internal thread cooperate to limit the positioning plate to the resistance ring on the periphery of the wheel body.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] By designing a detachable resistance ring and wheel body structure, when the resistance ring is worn or damaged due to long-term use, there is no need to dismantle the entire resistance wheel support rod. Just loosen and remove the positioning plate, re-install the resistance ring, and it can be replaced, which greatly improves the convenience and efficiency of maintenance; through the threaded connection between the annular groove and the positioning plate, combined with the snap sleeve, the resistance ring is effectively limited to prevent it from displacement or falling off during operation, further ensuring the normal operation of the banknote counter.

[0016] In summary, the resistance wheel of the banknote counter of the present invention not only improves the convenience and efficiency of maintenance, but also enhances the stability and reliability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] like Figure 1-3 As shown, the utility model provides a technical solution: a resistance wheel of a banknote counter, comprising a resistance ring 1 and a wheel body 2, the wheel body 2 being composed of three sections, the periphery of the middle section wheel body 2 being butted with a snap-fit ​​sleeve 3, the peripheries of the two sections of the wheel body 2 at both ends of the middle section wheel body 2 being sleeved with resistance rings 1, the wheel body 2 being fixedly mounted on the resistance wheel support rod, and when replacing the resistance ring, there is no need to disassemble the resistance ring and the support rod;

[0030] The inner side of the resistance ring 1 is provided with a surrounding embedded groove 21, and a clamping ring 22 is provided around the outer periphery of the wheel body 2 corresponding to the embedded groove 21. Annular notches 4 are provided near the outer periphery at both ends of the wheel body 2, and the annular notches 4 are threadedly connected to the positioning plates 5.

[0031] Through the above embodiment, the clamping sleeve 3 limits the inner side of the resistance ring 1, and the positioning plate 5 limits the outer side of the resistance ring 1, thereby ensuring the stability of the installation of the resistance ring 1. Example 2

[0032] like Figure 2 As shown, the clamping sleeve 3 includes an upper clamping sleeve 31 and a lower clamping sleeve 32, both of which have semicircular cross-sections. The corresponding ends of the upper clamping sleeve 31 and the lower clamping sleeve 32 are respectively provided with a clamping block 33 and a clamping groove 34. The outer side of the clamping block 33 is provided with a clamping strip 35 along the length direction, and the corresponding clamping strip 35 is clamped with a clamping slot 36 in the clamping groove 34.

[0033] The clamping block 33 and the clamping slot 34 are adapted to be clamped together, and the clamping slots 36 and the clamping slots 36 are adapted to be clamped together.

[0034] like Figure 2 and Figure 3 As shown, the cross-section of the embedded groove 21 is convex, and the cross-section of the clamping ring 22 is convex. The resistance ring 1 is installed by clamping the convex clamping ring 22 into the convex embedded groove 21. The matching design of the convex embedded groove 21 and the convex clamping ring 22 ensures a stable connection between the resistance ring 1 and the wheel body.

[0035] like Figure 2 As shown, an external thread 41 is provided on the inner circular wall of the annular notch 4, and a docking ring 51 is provided at the end of the positioning plate 5 corresponding to the annular notch 4, and an internal thread 52 is provided on the periphery of the docking ring 51.
