The spring pops out the card block to insert it into the card slot to complete the limit.

[0028] Compared with the prior art, the utility model has the following beneficial effects:

[0029] The detachable magnetic head of the money counter pulls the bent rod, which enables the pulling piece to provide a pulling force to the card block, so that the card block compresses the spring. At this time, the card block will enter the cavity. As the bent rod continues to exert force, the positioning block can be pulled out of the positioning groove. At this time, the magnetic head body can be disassembled in the bottom groove, which makes it more convenient to disassemble the magnetic head body.

[0030] During the disassembly process, you only need to pull the bent rod to unlock it, and then you can take out the head body. The operation is simple and fast.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Example 1

[0038] A detachable magnetic head, such as Figure 1-3 As shown, it includes a magnetic head body 4, a base 2 and a limiting mechanism;

[0039] The base 2 is provided with a bottom groove 3, the magnetic head body 4 is provided with a positioning groove 5, and the magnetic head body 4 is assembled in the bottom groove 3 through a limiting mechanism;

[0040] The limiting mechanism includes a positioning block 7, a bent rod 8 and a clamping block 9; the positioning block 7 and the clamping block 9 are arranged on the inner side of the base 2, and the bent rod 8 is arranged on the outer side of the base 2 and connected to the positioning block 7;

[0041] The positioning block 7 is provided with a cavity 10, and a spring is provided inside the cavity 10, one end of the spring is connected to the inner wall of the cavity 10, and the other end of the spring is connected to the clamping block 9;

[0042] The end of the bending rod 8 is provided with a pulling member 12, which penetrates the spring and is connected to the clamping block 9, and is used to pull the clamping block 9 into the cavity 10;

[0043] The positioning block 7 is inserted into the positioning groove 5 , and the locking block 9 cooperates with the locking groove provided in the positioning groove 5 to achieve the limiting of the magnetic head body 4 in the bottom groove 3 .

[0044] More specifically, in this embodiment:

[0045] See also Figure 1-3The detachable magnetic head comprises a bottom plate 1 and a magnetic head body 4. A base 2 is fixedly arranged on the bottom plate 1, a bottom groove 3 is arranged inside the base 2, and the magnetic head body 4 is inserted into the bottom groove 3. A plurality of positioning grooves 5 are symmetrically arranged at the bottom of the magnetic head body 4, and a clamping groove is further arranged on the inner wall of the positioning groove 5. The magnetic head body 4 is detachably assembled in the bottom groove 3 through the combination of the positioning groove 5, the clamping groove and the limiting mechanism.

[0046] Assembly holes are provided at the four corners of the bottom plate 1 for assembling the detachable magnetic head inside the banknote counting machine.

[0047] The limiting mechanism specifically comprises a bending rod 8 , a positioning plate 6 , a positioning block 7 and a clamping block 9 .

[0048] A plurality of positioning plates 6 are symmetrically arranged on both sides of the base 2. In this embodiment, four positioning plates 6 are arranged. Figure 1 As shown, two are provided on each of the left and right side walls of the base 2, and the two positioning plates 6 on the same side are connected by a bent rod 8. The positioning plate 6 is provided with a positioning block 7 which passes through the base 2 and is inserted into the positioning slot 5. The interior of the positioning block 7 is provided with a cavity 10. The interior of the cavity 10 is provided with a spring. One end of the spring is connected to a clamping block 9 which cooperates with the clamping slot, and the other end of the spring is connected to the inner wall of the cavity 10. The base 2, the positioning block 7, and the positioning plate 6 are all provided with a pulling channel 11 connected to the cavity 10. Both ends of the bent rod 8 are provided with a pulling member 12 which passes through the pulling channel 11. The other end of the pulling member 12 passes through the spring and is connected to the clamping block 9. The pulling member 12 can be a pull rope, which can synchronously pull the two positioning blocks 7 and the clamping block 9 on the same side when the bent rod 8 is pulled outward. The clamping block 9, as shown Figure 3 In the embodiment, a chamfer is provided on one side facing outward (backwards from the cavity), so that when there is a certain deviation in the placement position of the magnetic head body 4 or the insertion position of the positioning block 7, it can still smoothly slide into the card slot to form a matching relationship to play a limiting role; Figure 2 In the embodiment, the positioning block 7 and the clamping block 9 (connected to the same bending rod 8) on the same side are arranged facing each other.

[0049] When the head body 4 is inserted into the bottom slot 3 (the positioning block 7 is pulled by the bending rod 8 in advance to avoid the position of the head body 4), the positioning plate 6 is pushed to insert the positioning block 7 into the positioning slot 5. At this time, the spring can provide an elastic force to the card block 9, so that the card block 9 can enter the card slot. Through the cooperation between the card block 9 and the card slot, the installation of the head body 4 in the bottom slot 3 is more secure.

[0050] When the magnetic head body 4 needs to be replaced or overhauled, the outer shell of the money counter is disassembled, and then the bent rod 8 is pulled, which can make the pulling member 12 provide an outward pulling force to the card block 9, so that the card block 9 compresses the spring. At this time, the card block 9 will enter the cavity 10. As the bent rod 8 continues to exert force, the positioning block 7 will be pulled out of the positioning groove 5. At this time, the magnetic head body 4 can be removed from the bottom groove 3.

[0051] In this structure, a groove 13 is further provided at the bottom center of the bottom groove 3, and the groove 13 penetrates the base 2 in the front-rear direction (the base 2 is open at the position where the groove 13 is provided), and a disassembly plate 14 extending out of the base 2 is provided inside the groove 13, and a toggle block is further provided at both ends of the disassembly plate 14, forming a U-shaped structure. When the positioning block 7 is separated from the positioning groove 5, a pulling force is provided to both ends of the disassembly plate 14, so that the disassembly plate 14 can rise in the groove 13, so that the disassembly plate 14 can provide an upward force to the magnetic head body 4, so that the magnetic head body 4 can be easily disassembled in the bottom groove 3.

[0052] Furthermore, a circular hole is provided at the top of the toggle block, and the toggle blocks at both ends of the disassembly plate 14 can be more easily stressed through the circular hole.

[0053] Since there is a lack of a guide structure between the disassembly plate 14 and the base 2, the stability of the disassembly plate 14 during lifting and lowering will be affected. Therefore, a plurality of guide grooves 15 are arranged symmetrically to the grooves 13 in the middle part of the base 2 (the symmetrical arrangement is also adopted in this embodiment), and correspondingly, guide blocks cooperating with the guide grooves 15 are arranged on both sides of the two ends of the disassembly plate 14. When the disassembly plate 14 is in the process of rising, the guide blocks will move inside the guide grooves 15, which can provide a guide structure between the disassembly plate 14 and the base 2, thereby further improving the stability of the disassembly plate 14 during lifting and lowering.

[0054] Furthermore, the cross section of the guide groove 15 can be designed to be T-shaped to prevent the guide block from slipping in the horizontal direction.

[0055] In the above structure, the sizes of the multiple positioning blocks 7 are the same, and the sizes of the multiple positioning grooves 5 are the same.

[0056] The disassembly process only requires pulling the bent rod 8 outwards to achieve unlocking, which makes it more convenient to disassemble the magnetic head body 4.

[0057] The magnetic head body 4 is installed inside the banknote counting machine through the bottom plate 1 .

[0058] When the above structure is used as a whole:

[0059] When disassembling the head body 4: pull the bent rod 8 outward, first make the pulling member 12 pull the block 9 to put the block 9 into the cavity 10, then further pull the bent rod 8 outward, so that the positioning block 7 is pulled outward together with the positioning plate 6 and the bent rod 8 to disengage from the positioning groove 5; after the positioning block 7 is completely out of the positioning groove 5, lift the toggle block upward through the circular hole at the end of the toggle block to drive the disassembly plate 14 to lift the head body 4 upward, and then the head body 4 can be easily taken out from the bottom groove 3.

[0060] When assembling the head body 4: pull the bent rod 8 outward, first make the pulling piece 12 pull the card block 9 to put the card block 9 into the cavity 10, then further pull the bent rod 8 outward, make the positioning block 7 follow the positioning plate 6 and the bent rod 8 to be pulled outward together, so as to vacate the space for placing the head body 4; then place the head body 4 into the bottom groove 3, and then push the positioning plate 6 inward to push the positioning block 7 into the positioning groove 5. When the positioning block 7 is pushed into the positioning groove 5 and moves to the positioning position, the card block 9 pops out and extends into the card slot under the action of the spring, completing the limiting of the head body 4 in the bottom groove 3.

[0061] It can be seen that the detachable magnetic head of the present structure is easy to operate and has simple steps, and can quickly and conveniently realize the removal and assembly of the magnetic head body 4, thereby improving the speed and efficiency of maintenance.

[0062] During the use of the currency counter, the condition of the magnetic head body 4 has an important impact on the performance of the currency counter. The magnetic head body 4 may cause performance degradation due to long-term use or wear, thereby affecting the accuracy and efficiency of the currency counter. Therefore, regular inspection and replacement of the magnetic head body 4 is an important step to ensure the normal operation of the currency counter. In this regard, in the specific currency counter application of the magnetic head, as one of the expandable ideas, the existing big data analysis method can be further introduced to judge the detachable magnetic head of the currency counter: by collecting data such as the use data, fault records and wear of the magnetic head body 4 of the currency counter, the analysis equipment outside the currency counter (such as a computer loaded with a big data analysis program, connected to the currency counter, and the corresponding currency counter is internally provided with a communication module such as a Bluetooth module, a wireless module, etc., and the communication module is electrically connected to the chip built into the currency counter) to predict the best time to replace the magnetic head body 4. For example, the wear rate and life of the head body 4 can be estimated by analyzing the frequency of use of the currency counter, the duration of each use, and the errors or anomalies that occur during use (the built-in chips in conventional commercially available currency counters already have these recording functions). However, it should be noted that although big data analysis can provide valuable predictions and references, it cannot completely replace actual inspections and tests. This is because the wear of the head body 4 is actually affected by many factors, such as the use environment, usage habits, and the quality of banknotes. Therefore, while using big data analysis for predictions, it is also necessary to combine actual inspection and test results to make a final decision.

[0063] The above-mentioned method of introducing big data analysis is only to apply the existing technology to the banknote counting machine to determine the wear condition of the magnetic head body 4 (for example, the communication module can be loaded into the banknote counting machine and respectively communicated with the original control chip and the external analysis equipment, and then the communication module transmits the data recorded by the original control chip to the external analysis equipment, and then the analysis equipment analyzes the data through big data and combines manual judgment to draw conclusions). This part of the content is not the improvement point and improvement content of this solution, nor is it the protection content of this patent. It is only used as an example of the expansion idea of ​​a specific application.

[0064] In the description of this article, it should be noted that relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0065] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.

[0066] The above description of the embodiments is to facilitate the understanding and use of the utility model by those skilled in the art. It is obvious that those familiar with the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the utility model is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the utility model without departing from the scope of the utility model should be within the scope of protection of the utility model.
