Description

Technical Field

[0001] The present invention relates to the technical field of deposit devices, in particular to a deposit machine core. Background Art

[0002] The deposit device is a device used to automatically count the number of banknotes and select deposits, generally with a counterfeit banknote identification function. In the cash processing work of some enterprises, institutions and financial institutions, the deposit device has become an indispensable device.

[0003] In a general large-scale automatic deposit machine, such as the patent document with application publication number CN113706796A, a temporary storage module and a deposit movement on a deposit movement are disclosed. The deposit movement adopts a relatively complex structure, resulting in a large space occupied by the deposit device, which is not convenient for flexible configuration in cash processing.

[0004] In the patent document with the publication number CN110533148A, a banknote dispensing assembly of a banknote counting machine is disclosed. The patent provides a banknote depositing function that automatically deposits banknotes into a banknote collecting container after counting, and provides a depositing function on the basis of maintaining the compact structure of the banknote counting machine. The specific technical scheme of the patent is to set a banknote dispensing port at the bottom of the banknote collecting slot, and to set a swingable banknote dispensing flap at the banknote dispensing port and to be driven by a banknote dispensing driving mechanism. When counting banknotes, the banknote dispensing flap rests against the banknote dispensing port of the banknote collecting slot. When it is necessary to deposit banknotes into the banknote collecting container, the banknote dispensing flap is opened, and the banknotes fall from the banknote dispensing port. In the above patent technical scheme, for relatively flat banknotes, after the banknote dispensing flap is opened, they can smoothly fall from the banknote dispensing port at the bottom of the collecting slot; but for banknotes that are severely folded or curled before counting, they may be restored to the state shown in the attached figure in the collecting slot 91. Figure 1 In the folded state shown, the banknote 92 in this folded state may not be able to fall smoothly from the banknote outlet under its own weight, which may lead to errors in the amount of banknotes stored. Therefore, it is necessary to propose a technical solution that can enable the folded banknotes to fall smoothly into the banknote collection container. Summary of the invention

[0005] In order to overcome the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a deposit mechanism.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention to solve the technical problem is: a deposit machine core, comprising: A banknote receiving impeller is arranged at the end of the banknote transmission channel of the deposit device, a banknote taking port is arranged on the front side of the deposit device frame located at the banknote receiving impeller, and a downward banknote dropping port is arranged on the deposit device frame just below the front part of the banknote receiving impeller; A banknote dropping flap, the upper end of which is pivotally connected between the left side plate and the right side plate of the deposit device frame; A baffle assembly, comprising a main baffle and a sub-baffle, wherein the lower end of the main baffle is pivotally connected between the left and right plates of the deposit device frame, the lower end of the sub-baffle is rotatably connected to the upper end of the main baffle, and a straight limit structure for limiting the main baffle and the sub-baffle to be in a straight state is also provided between the main baffle and the sub-baffle; A linkage plate, one end of which has a long strip connecting hole, an end of the linkage plate away from the long strip connecting hole is hinged to one side of the main baffle, one side of the banknote falling flip plate is connected to the long strip connecting hole of the linkage plate via a sliding connecting pin, and the sliding connecting pin passes through the long strip connecting hole and can slide along the length direction of the long strip connecting hole; A banknote dropping driving mechanism, which is used to drive the banknote dropping flap to swing between a first angle position and a second angle position; When the banknote-dropping flap is at the first angle position, the lower end of the banknote-dropping flap abuts against the lower end of the main baffle, and driven by the linkage plate, the main baffle and the auxiliary baffle of the baffle assembly are located close to the banknote-taking port, and a spacing space for collecting banknotes is provided between the banknote-receiving impeller and the baffle assembly; When the banknote dropping flap is at the second angle position, a spacing space for residual banknotes to fall is formed between the banknote dropping flap and the baffle assembly, and driven by the linkage plate, the banknote contact surface of the baffle assembly contacts the banknote receiving impeller.

[0007] The technical solution of the present invention can form a space for stably collecting banknotes when the banknote-dropping flap is at a first angle position, and can realize taking out the counted banknotes from the banknote-taking port in this state according to the use requirements. When it is necessary to store the counted banknotes from the banknote-dropping port to the banknote collection container below the deposit device, the banknote-dropping flap is driven by the banknote-dropping driving mechanism to change from the first angle position to the second angle position, and the banknote-dropping flap is opened downward, and most of the banknotes will fall into the banknote collection container under their own weight; in order to prevent the residue of a few folded banknotes, when the banknote-dropping flap is swung to the second angle position, the baffle assembly contacts the blades of the banknote-receiving impeller under the drive of the linkage plate, and the residual folded banknotes can be sent into the banknote collection container by continuing to rotate the banknote-receiving impeller. The present invention reliably realizes the functions of receiving banknotes, dropping banknotes, and cleaning residual folded banknotes through the linkage combination of the banknote-dropping flap, the linkage plate, and the baffle assembly, ensuring that all the counted banknotes can fall into the banknote collection container, significantly improving the reliability of the banknote depositing function of the deposit device, and improving the user experience. The deposit mechanism of the present invention has a compact and ingenious structure, and can still maintain the characteristics of a small device structure, which is convenient to use.

[0008] Furthermore, when the banknote falling flap is in the first angle position, the banknote contact surface of the banknote falling flap is arranged obliquely downward from top to bottom and its angle with the horizontal plane is 45°, and the banknote contact surface of the baffle assembly is arranged obliquely upward from bottom to top and its angle with the horizontal plane is 120°.

[0009] The adoption of the above preferred solution helps to keep a large number of collected banknotes close to each other in sequence and maintain a stable oblique upright state, making it convenient to take out the banknotes.

[0010] Furthermore, when the banknote falling flap is at the second angle position, the banknote contact surface of the banknote falling flap is arranged vertically downward from top to bottom, and the banknote contact surface of the baffle assembly is arranged obliquely upward from bottom to top and its angle with the horizontal plane is less than 90°.

[0011] The adoption of the above preferred solution helps possible folded residual banknotes to fall smoothly into the banknote collection container.

[0012] Furthermore, in the process of the banknote falling flap plate swinging from the first angle position to the second angle position, the sliding connecting pin moves in the elongated connecting hole from the end close to the middle position of the linkage plate to the end away from the middle position of the linkage plate. When it just starts to collide with the end wall of the elongated connecting hole, that is, when the banknote falling flap plate is about to pull the baffle assembly through the linkage plate, the banknote contact surface of the banknote falling flap plate is arranged obliquely downward from top to bottom and its angle with the horizontal plane is 75°-80°, and the banknote contact surface of the baffle assembly is arranged obliquely upward from bottom to top and its angle with the horizontal plane is 120°.

[0013] By adopting the above preferred solution, after the banknote dropping flap is opened, the baffle assembly and the banknote receiving impeller maintain the previous spacing, ensuring that the collected regular banknotes can fall into the banknote collecting container quickly and smoothly.

[0014] Furthermore, it also includes a shielding cover assembly, which includes an arc-shaped shielding cover, a left ear plate and a right ear plate, wherein the left ear plate and the right ear plate are respectively fixedly connected to the left side and the right side of the arc-shaped shielding cover, and one end of the left ear plate and the right ear plate away from the arc-shaped shielding cover is pivotally connected to the deposit device frame; it also includes an opening and closing driving mechanism for driving the shielding cover assembly to swing, and under the drive of the opening and closing driving mechanism, the arc-shaped shielding cover switches between a state of completely covering the banknote withdrawal port and a state of completely detaching from the banknote withdrawal port.

[0015] By adopting the above preferred solution, the shielding cover assembly can close the banknote withdrawal port when counting banknotes, preventing the outside from interfering with the banknote counting and improving security at the same time.

[0016] Furthermore, an upper baffle is provided above the banknote withdrawal port, and a downwardly bent outer baffle is provided at the outer end of the upper baffle near the banknote withdrawal port. When the arc-shaped shielding cover completely covers the banknote withdrawal port, the top of the arc-shaped shielding cover is located on the inner side of the outer baffle.

[0017] The above preferred solution can prevent the arc-shaped shielding cover from being manually pulled open from above.

[0018] Furthermore, a lower baffle is provided below the banknote withdrawal port, and the lower baffle includes an inclined portion and a horizontal portion which are arranged at an angle. When the banknote dropping flap is in a banknote receiving state at a first angle position, the back side of the main baffle of the baffle assembly abuts against the inclined portion of the lower baffle. When the auxiliary baffle is folded outward to a horizontal state, the auxiliary baffle passes through the banknote withdrawal port, and the back side of the auxiliary baffle abuts against the horizontal portion of the lower baffle.

[0019] With the above preferred solution, the lower baffle supports the baffle assembly, which can keep the baffle assembly at a stable angle. When it is necessary to directly take out banknotes from the banknote withdrawal port, the auxiliary baffle is folded outward to a horizontal state, which facilitates taking out banknotes from the banknote withdrawal port.

[0020] Furthermore, when the main baffle and the auxiliary baffle are in a straight state, the width of the banknote contact surface formed by the main baffle and the auxiliary baffle is 5-10 mm wider than the width of the largest size banknote.

[0021] By adopting the above preferred solution, the counted banknotes can be better collected and regulated to keep the banknotes neat.

[0022] Furthermore, the width of the banknote contact surface of the main baffle is greater than 1 / 2 of the width of the largest banknote.

[0023] The above preferred solution ensures that after the auxiliary baffle is turned outward, the collected banknotes can still maintain a stable oblique standing state.

[0024] Furthermore, the upper part of the auxiliary baffle is also provided with an inwardly bent portion, and the angle formed by the inner surface of the inwardly bent portion and the banknote contact surface of the auxiliary baffle is less than 180°; when the banknote falling flap is in the banknote receiving state of the first angle position and the arc-shaped shielding cover completely covers the banknote withdrawal port, the minimum gap between the top end of the inwardly bent portion of the auxiliary baffle and the inner wall surface of the arc-shaped shielding cover is 0.1mm-2mm, and the distance between the top end of the inwardly bent portion and the upper baffle is 20mm-30mm.

[0025] By adopting the above preferred solution, a small gap is maintained between the auxiliary baffle and the inner wall of the arc-shaped shielding cover to prevent the banknotes flying out during the counting process from falling outside the auxiliary baffle through the gap. At the same time, when the auxiliary baffle is still turned outward after the last banknote withdrawal, the arc-shaped shielding cover automatically closes and drives the auxiliary baffle to turn inward. The small gap can ensure that the auxiliary baffle turns inward to the magnetic force range of the magnetic suction part, so that the auxiliary baffle is in a straight state with the main baffle after turning inward. The spacing of 20 mm to 30 mm between the top of the inward bending part and the upper baffle can facilitate the finger of the banknote withdrawer to insert into the inner side of the auxiliary baffle to turn the auxiliary baffle outward.

[0026] Furthermore, at least two downwardly hanging chains are provided on the upper baffle, and the chains are formed by a plurality of rings connected in series; when the banknote falling flap is in a banknote receiving state at a first angle position, and the main baffle and the auxiliary baffle are in a straight state, the chains extend downward to the inner side of the inwardly bent portion of the auxiliary baffle and are lower than the top of the inwardly bent portion, and the length of the lower end of the chains below the top of the inwardly bent portion is less than the horizontal distance between the chains and the top of the inwardly bent portion when the chains are in a drooping state.

[0027] By adopting the above preferred solution, the clever design of the hanging chain not only does not hinder the flipping action of the baffle assembly, but also can effectively prevent the banknotes that may fly out during the counting process from running from the upper gap of the auxiliary baffle to the outside of the auxiliary baffle and unable to return to the banknote collection space. The control of the hanging chain's drooping length and the horizontal distance between the hanging chain and the auxiliary baffle can ensure that after the baffle assembly is turned inward and then restored, the hanging chain can return to the inside of the inward bending portion.

[0028] Furthermore, a light detection sensor for detecting whether there is a banknote attached to the banknote contact surface of the main baffle is installed on the back of the inclined portion of the lower baffle, and the main baffle is provided with a through hole running through the front and back for the light path of the light detection sensor to pass through, or the main baffle is made of transparent material.

[0029] By adopting the above preferred solution, it is possible to timely detect whether there are banknotes remaining in the banknote collection space. After detecting the presence of banknotes, the banknote-dropping driving mechanism can drive the banknote-dropping flip plate and the baffle assembly to repeatedly perform flipping actions to clean the remaining banknotes into the banknote collection space. If banknotes are still detected after multiple flipping and cleaning actions, an alarm prompt is issued for timely manual inspection.

[0030] Furthermore, the straight limiting structure includes a left protrusion located at the left side of the lower end of the auxiliary baffle and protruding toward the side where the main baffle is located, a right protrusion located at the right side of the lower end of the auxiliary baffle and protruding toward the side where the main baffle is located, a left groove body located at the left side of the upper end of the main baffle, and a right groove body located at the right side of the upper end of the main baffle, a first magnetic attraction component is provided in the left groove body and the right groove body, and a second magnetic attraction component is provided on the back side of the left protrusion and the right protrusion, and after the first magnetic attraction component and the second magnetic attraction component are attracted to each other, the main baffle and the auxiliary baffle are in a straight state.

[0031] With the above preferred solution, when taking out money, after the auxiliary baffle is turned outward, the two magnetic parts are out of the range of magnetic attraction, and the auxiliary baffle can be turned outward freely to a horizontal state without hindering the action of taking money. After the auxiliary baffle is turned inward, it enters the range of magnetic attraction of the two magnetic parts, and the baffle and the auxiliary baffle can be smoothly in a straight state.

[0032] Furthermore, a middle protrusion is provided at the middle of the lower end of the auxiliary baffle, which protrudes toward the side where the main baffle is located, and the protrusions of the left and right protrusions are more than 10 mm greater than the protrusion of the middle protrusion.

[0033] By adopting the above preferred solution, when taking out banknotes, after the auxiliary baffle is turned outward, the left protrusion and the right protrusion can push the collected banknotes forward, so that a gap will appear between the banknotes and the middle position of the auxiliary baffle, making it easier for the person who takes out banknotes to insert his fingers and grab the banknotes.

[0034] Furthermore, ribs extending into one side of the other and grooves accommodating the ribs extending out of the other side are alternately provided at the junction of the upper end of the main baffle and the lower end of the auxiliary baffle, and ribs extending into one side of the other side and grooves accommodating the ribs extending out of the other side are also alternately provided at the junction of the lower end of the banknote falling flip plate and the lower end of the main baffle.

[0035] By adopting the above preferred solution, banknotes can be prevented from entering the interface gap between the two components, thus preventing banknotes from getting stuck.

[0036] Furthermore, the banknote receiving impeller comprises two impellers arranged in parallel and at intervals, an air blowing hole is respectively arranged below each impeller on the banknote dropping flap, an inclined surface block is arranged in the deposit device frame below the banknote receiving impeller, and guide boxes movable along the inclined surface are respectively installed on the inclined surface of the inclined surface block corresponding to the positions directly below the two impellers, the top surface of the guide box has an arc surface matching the outer contour of the impeller, and a plurality of concave semi-ellipsoidal air collecting grooves are arranged on the arc surface, and each of the air collecting grooves is provided with a plurality of concave semi-ellipsoidal air collecting grooves, and each of the air collecting grooves is provided with a plurality of concave semi-ellipsoidal air collecting grooves, and each of the air collecting grooves is provided with a plurality of concave semi-ellipsoidal air collecting grooves, and each of the air collecting grooves is provided with a plurality of concave semi-ellipsoidal air collecting grooves, and each of the impeller ... The bottom of the groove is gathered to the air outlet pipe through the air duct, and the mouth of the air outlet pipe faces the air hole of the banknote falling flap; when the banknote falling flap is swung down to the second angle position, the guide box moves backward along the inclined block and rises, so that the blades of each impeller of the banknote receiving impeller are in contact with the corresponding arc surface of the guide box; after the banknote falling flap is swung away from the second angle position, the guide box moves forward along the inclined block and descends, so that the blades of each impeller of the banknote receiving impeller are separated from the corresponding arc surface of the guide box.

[0037] By adopting the above-mentioned preferred scheme, after the banknote falling flap is flipped to the second angle position, the banknote receiving impeller rotates to scrape the banknote contact surface of the baffle assembly, and at the same time, the blade contacts the curved surface of the guide box, which will generate airflow to the semi-ellipsoidal air collecting groove, and the airflow is guided to the blowing holes of the banknote falling flap through the air duct and the air outlet duct to be blown out, which can blow off the residual banknotes that may be attached to the surface of the banknote falling flap, further ensuring that all banknotes can smoothly fall into the banknote collection container, and ensuring the accuracy of the deposited banknote quantity.

DETAILED DESCRIPTION

[0062] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0063] like Figure 2 , Figure 3As shown, the deposit device includes a banknote input bin 81, a banknote transmission channel 82, a counterfeit banknote detection module 83, a genuine banknote channel switching mechanism 84, a counterfeit banknote collection bin 85, and a deposit mechanism for collecting genuine banknotes. Banknotes that need to be counted are sequentially fed from the banknote input bin 81 into the banknote transmission channel 82, and the authenticity is identified at the counterfeit banknote detection module 83. After the identification, the counterfeit banknotes are sent to the counterfeit banknote collection bin 85 through the reversal of the genuine banknote channel switching mechanism 84, and the genuine banknotes are continuously transmitted to the end of the banknote transmission channel and collected by the deposit mechanism. In order to solve the technical problems raised by the background technology, the present invention proposes a technical solution for improving the deposit mechanism.

[0064] like Figure 2-Figure 17 As shown, one embodiment of the present invention is: a deposit machine movement, comprising: The banknote receiving impeller 10 is arranged at the end of the banknote transmission channel of the deposit device, a banknote taking port 803 is arranged on the front side of the banknote receiving impeller 10 of the deposit device frame 80, and a banknote dropping port 804 facing downward is arranged just below the front part of the banknote receiving impeller 10 of the deposit device frame 80; The banknote dropping flap 20 has its upper end pivotally connected between the left side plate 801 and the right side plate 802 of the deposit device frame 80; The baffle assembly 30 includes a main baffle 31 and a sub-baffle 32. The lower end of the main baffle 31 is pivotally connected between the left side plate 801 and the right side plate 802 of the deposit device frame. The lower end of the sub-baffle 32 is rotatably connected to the upper end of the main baffle 31. A straight limit structure is also provided between the main baffle 31 and the sub-baffle 32 for limiting the two to a straight state. The straight state refers to that the banknote contact surface of the sub-baffle 32 and the banknote contact surface of the main baffle 31 are in the same plane state ( Fig.12 In the state shown in the figure, a first magnetic member 313 is further provided on the straight limiting structure on the main baffle 31, and a second magnetic member 323 is further provided on the straight limiting structure on the auxiliary baffle 32, and a magnetic attraction force can be generated between the first magnetic member 313 and the second magnetic member 323; The linkage plate 40 has a long strip connection hole 41 at one end. The end of the linkage plate 40 away from the long strip connection hole 41 is hinged to one side of the main baffle 31. One side of the banknote falling flip plate 20 is connected to the long strip connection hole 41 of the linkage plate via a sliding connection pin 21. The sliding connection pin 21 passes through the long strip connection hole 41 and can slide along the length direction of the long strip connection hole. A banknote dropping driving mechanism 22, which is used to drive the banknote dropping flap 20 to swing between a first angular position and a second angular position; When the banknote falling flap 20 is at the first angle position ( Figure 4 and Figure 5In the state shown in the figure, the banknote falling flap 20 and the baffle assembly 30 are combined into a banknote receiving state for receiving and collecting banknotes, the lower end of the banknote falling flap 20 abuts against the lower end of the main baffle 31, the sliding connecting pin 21 abuts against the first end 411 of the long strip connecting hole 41 near the middle position of the linkage plate, and driven by the linkage plate 40, the baffle assembly 30 is located near the banknote withdrawal port, and there is a spacing space for collecting banknotes between the banknote receiving impeller 10 and the baffle assembly 30; When the banknote falling flap is at the second angle position ( Figure 8 and Fig. 9 In the state shown in the figure, the banknote falling flap 20 and the baffle assembly 30 are combined into a banknote clearing state for cleaning the residual banknotes into the banknote collecting container below the banknote falling port. A spacing space for the residual banknotes to fall is formed between the banknote falling flap 20 and the baffle assembly 30. Driven by the linkage plate 40, the banknote contact surface of the baffle assembly 30 contacts the banknote receiving impeller 10. After the banknote receiving impeller 10 starts to rotate, the residual banknotes enter the banknote collecting container through the banknote falling port.

[0065] like Fig.16 As shown, the end of the long strip connection hole 41 close to the middle position of the linkage plate is the first end 411, and the end of the long strip connection hole 41 away from the middle position of the linkage plate is the second end 412. Figure 6 , Figure 7 As shown, during the swinging process of the banknote dropping flip plate 20 from the first angular position to the second angular position, the sliding connecting pin 21 moves from the first end 411 to the second end 412 in the long strip connecting hole 41, and when it just contacts the end wall of the second end 412, the position of the banknote dropping flip plate 20 at this time is the third angular position ( Figure 6 and Figure 7 In the state shown in the figure, the banknote dropping flap 20 and the baffle assembly 30 are combined into a banknote dropping state for dropping banknotes to the banknote collecting container below the banknote dropping port, the lower end of the banknote dropping flap 20 is separated from the lower end of the main baffle 31 and a spacing space for banknotes to drop is formed between the two, and a spacing space for banknotes to drop is maintained between the baffle assembly 30 and the banknote receiving impeller 10. When the banknote dropping flap 20 continues to swing from the third angle position to the second angle position, the linkage plate 40 pulls the baffle assembly 30 to gradually approach the banknote receiving impeller 10.

[0066] The beneficial effect of adopting the above technical solution is: through the linkage combination of the banknote dropping flap, the linkage plate and the baffle assembly, the functions of receiving banknotes, dropping banknotes and cleaning residual folded banknotes are reliably realized, ensuring that all banknotes counted can fall into the banknote collection container, significantly improving the reliability of the banknote deposit function of the deposit device and improving the user experience.

[0067] like Figure 5As shown, in other embodiments of the present invention, when the banknote falling flap 20 is at the first angle position, the banknote contact surface of the banknote falling flap 20 is set obliquely downward from top to bottom and the angle α1 between it and the horizontal plane is 45°, and the banknote contact surface of the baffle assembly 30 is set obliquely upward from bottom to top and the angle β1 between it and the horizontal plane is 120°. The beneficial effect of adopting the above technical solution is that it helps a large number of collected banknotes to be closely aligned in sequence and maintain a stable oblique upright state, which is convenient for taking banknotes.

[0068] like Fig. 9 As shown, in other embodiments of the present invention, when the banknote falling flap 20 is at the second angle position, the banknote contact surface of the banknote falling flap 20 is vertically arranged downward from top to bottom, and its angle α2 with the horizontal plane is 90°, and the banknote contact surface of the baffle assembly 30 is obliquely arranged upward from bottom to top, and its angle β2 with the horizontal plane is less than 90°. The beneficial effect of adopting the above technical solution is that it helps the possible folded residual banknotes to fall smoothly into the banknote collection container.

[0069] like Figure 7 As shown, in other embodiments of the present invention, when the banknote falling flap 20 is at the third angle position, the banknote contact surface of the banknote falling flap 20 is set obliquely downward from top to bottom and the angle α3 between it and the horizontal plane is 75°-80°, and the banknote contact surface of the baffle assembly 30 is set obliquely upward from bottom to top and the angle β3 between it and the horizontal plane is 120°. The beneficial effect of adopting the above technical solution is that after the banknote falling flap is opened, the baffle assembly and the banknote receiving impeller maintain the previous spacing, ensuring that the collected regular banknotes can quickly and smoothly fall into the banknote collection container.

[0070] In some other embodiments of the present invention, the banknote-dropping flap 20 is fixedly connected to its pivot, and the pivot is mounted on the side plate of the deposit device frame via a bearing. The specific structural form of the banknote-dropping driving mechanism is not limited, and can be selected from a driving mechanism that can achieve swinging in the prior art. For example, the banknote-dropping driving mechanism can directly use a reduction motor to be directly connected to the banknote-dropping flap pivot via a coupling. Fig.17As shown, in order to facilitate the spatial layout of the banknote dropping driving mechanism on the deposit device frame, the banknote dropping driving mechanism can also adopt the structural form of a motor, a reduction transmission mechanism and a toothed transmission belt. Specifically, the reduction transmission mechanism adopts a worm gear reduction transmission mechanism, the output shaft of the motor is connected to the input end of the worm gear reduction transmission mechanism, an active toothed transmission wheel 221 is installed on the output shaft of the worm gear reduction transmission mechanism, a driven toothed transmission wheel 222 is installed at the pivot end of the banknote dropping flap, and a toothed transmission belt 223 is wound between the active toothed transmission wheel 221 and the driven toothed transmission wheel 222. For example, to achieve precise control of the swing angle of the banknote dropping flap, a detection rod 224 for shielding the sensor light path is installed at the pivot end of the banknote dropping flap, and a photoelectric sensor 225 is respectively arranged on the deposit device frame at the swing angle boundary position of the detection rod 224. When the detection rod 224 blocks the light path of the photoelectric sensor 225, it means that the banknote dropping flap has reached the set swing angle position.

[0071] like Fig.17 As shown, in some other embodiments of the present invention, a shielding cover assembly is also included, wherein the shielding cover assembly includes an arc-shaped shielding cover 51, a left ear plate 52 and a right ear plate, wherein the left ear plate 52 and the right ear plate are respectively fixedly connected to the left and right sides of the arc-shaped shielding cover 51, and the ends of the left ear plate 52 and the right ear plate away from the arc-shaped shielding cover are pivotally connected to the deposit device frame; and an opening and closing driving mechanism 53 is also included to drive the shielding cover assembly to swing, and driven by the opening and closing driving mechanism 53, the arc-shaped shielding cover 51 switches between a state of completely shielding the banknote withdrawal port and a state of completely detaching from the banknote withdrawal port. The beneficial effect of adopting the above technical solution is that the shielding cover assembly can close the banknote withdrawal port when counting banknotes, preventing the outside from interfering with the banknote counting, and improving safety at the same time.

[0072] In other embodiments of the present invention, the specific structural form of the opening and closing driving mechanism for driving the shielding cover assembly to swing is not limited, and can be selected from the driving mechanism that can achieve swinging in the prior art. For example, a reduction motor can be directly used to drive the pivot fixedly connected to the left ear plate and the right ear plate to achieve the swinging of the shielding cover assembly, or a reduction motor can be used in conjunction with a transmission mechanism to drive the pivot to rotate to achieve the swinging of the shielding cover assembly. The specific structural form will not be repeated here.

[0073] like Fig.18 , Fig.19 As shown, in other embodiments of the present invention, an upper baffle 61 is provided above the banknote withdrawal port 803, and an outer baffle 611 bent downward is provided at the outer end of the upper baffle 61 near the banknote withdrawal port, and when the arc-shaped shielding cover 51 completely shields the banknote withdrawal port 803, the top of the arc-shaped shielding cover 51 is located on the inner side of the outer baffle 611. The beneficial effect of adopting the above technical solution is that it can prevent the arc-shaped shielding cover from being manually pulled open from the top.

[0074] like Fig.18 , Fig.19 As shown, in some other embodiments of the present invention, a lower baffle 63 is provided below the banknote withdrawal port 803, and the lower baffle 63 includes an inclined portion 631 and a horizontal portion 632 arranged at an angle. When the banknote dropping flap 20 is in a banknote receiving state at a first angle position, the back of the main baffle 31 of the baffle assembly abuts against the inclined portion 631 of the lower baffle. When the auxiliary baffle 32 is folded outward to a horizontal state, the auxiliary baffle 32 passes through the banknote withdrawal port 803, and the back of the auxiliary baffle 32 abuts against the horizontal portion 632 of the lower baffle. The beneficial effect of adopting the above technical solution is that the lower baffle supports the baffle assembly, and the baffle assembly can maintain a stable angle state. When it is necessary to directly withdraw banknotes from the banknote withdrawal port, the auxiliary baffle is folded outward to a horizontal state, so as to facilitate the withdrawal of banknotes from the banknote withdrawal port.

[0075] like Fig.12 As shown, in some other embodiments of the present invention, when the main baffle 31 and the auxiliary baffle 32 are in a straight state, the width b1 of the banknote contact surface formed by the main baffle 31 and the auxiliary baffle 32 is 5-10 mm wider than the width of the largest size banknote. The beneficial effect of adopting the above technical solution is that it can better collect and regulate the counted banknotes to keep the banknotes neat.

[0076] like Fig.14 As shown, in some other embodiments of the present invention, the width b2 of the banknote contact surface of the main baffle 31 is slightly larger than 1 / 2 of the maximum banknote width. The beneficial effect of the above technical solution is to ensure that the collected banknotes can still maintain a stable oblique standing state after the auxiliary baffle is turned outward.

[0077] like Fig.14 , Fig.15 As shown, in some other embodiments of the present invention, the flat limit structure includes a left protrusion 321 located at the left side of the lower end of the auxiliary baffle 32 and protruding toward the side where the main baffle is located, a right protrusion 322 located at the right side of the lower end of the auxiliary baffle 32 and protruding toward the side where the main baffle is located, a left slot 311 located at the left side of the upper end of the main baffle 31, and a right slot 312 located at the right side of the upper end of the main baffle 31, a first magnetic member 313 is provided in the left slot 311 and the right slot 312, and a second magnetic member 323 is provided on the back of the left protrusion 321 and the right protrusion 322. After the first magnetic member 313 and the second magnetic member 323 are attracted, the main baffle 31 and the auxiliary baffle 32 are in a flat state. The specific matching form of the first magnetic member 313 and the second magnetic member 323 is not limited, and two magnets of opposite sex attraction can be used, or one side can use a magnet and the other side can use an iron sheet attracted to the magnet.

[0078] like Fig.15As shown, in other embodiments of the present invention, a middle protrusion 327 protruding toward the side where the main baffle is located is provided at the middle of the lower end of the auxiliary baffle 32, and the protrusion of the left protrusion 321 and the right protrusion 322 is more than the protrusion of the middle protrusion 327 by a length b3 of 10 mm or more. The beneficial effect of adopting the above technical solution is that when taking out money, after the auxiliary baffle is turned outward, the left protrusion and the right protrusion can push the collected banknotes forward, so that a gap will appear between the banknotes and the middle position of the auxiliary baffle, which is convenient for the banknote taker to put his fingers into the gap and more convenient to grab the banknotes.

[0079] like Fig.18 As shown, in some other embodiments of the present invention, the upper portion of the auxiliary baffle 32 is further provided with an inwardly bent portion 324, and the angle formed by the inner surface of the inwardly bent portion 324 and the banknote contact surface of the auxiliary baffle 32 is less than 180°; when the banknote falling flap 20 is in the banknote receiving state of the first angle position and the arc-shaped shielding cover 51 completely covers the banknote withdrawal port, the minimum gap b4 between the top end of the inwardly bent portion 324 of the auxiliary baffle and the inner wall surface of the arc-shaped shielding cover 51 is 0.1mm-2mm, and the minimum spacing b5 between the top end of the inwardly bent portion 324 and the upper baffle 61 is 20mm-30mm. The beneficial effects of the above technical solution are: the small gap b4 between the auxiliary baffle and the inner wall of the arc-shaped shielding cover can prevent the banknotes flying out during the counting process from falling outside the auxiliary baffle through the gap. At the same time, when the auxiliary baffle is still turned outward after the last banknote withdrawal, the arc-shaped shielding cover automatically closes and drives the auxiliary baffle to turn inward. The small gap can ensure that the auxiliary baffle turns inward to the magnetic force range of the magnetic suction part, so that the auxiliary baffle is in a straight state with the main baffle after turning inward. The spacing b5 of 20 mm to 30 mm between the top of the inward bending part and the upper baffle can facilitate the finger of the banknote withdrawer to insert into the inner side of the auxiliary baffle to turn the auxiliary baffle outward.

[0080] like Fig.18 As shown, in some other embodiments of the present invention, at least two hanging chains 62 are also provided on the upper baffle 61, and the hanging chains 62 are formed by connecting a plurality of rings in series; when the banknote falling flap 20 is in the banknote receiving state at the first angle position, and the main baffle 31 and the auxiliary baffle 32 are in a straight state, the hanging chains 62 extend downward to the inner side of the inward bending portion 324 of the auxiliary baffle and are lower than the top of the inward bending portion, and the length b6 of the lower end of the hanging chain 62 below the top of the inward bending portion 324 is less than the horizontal distance b7 between the hanging chain 62 and the top of the inward bending portion 324 when the hanging chain 62 is in a drooping state. The beneficial effect of adopting the above technical solution is that the ingenious design of the hanging chain does not hinder the flipping action of the baffle assembly, and can effectively prevent the banknotes that may fly out during the counting process from running from the upper gap of the auxiliary baffle to the outside of the auxiliary baffle and unable to return to the banknote collection space. The control of the hanging length of the hanging chain and the horizontal distance between the hanging chain and the auxiliary baffle can ensure that after the baffle assembly is turned inward and then restored, the hanging chain can return to the inner side of the inward bending portion.

[0081] like Fig.18 As shown, in other embodiments of the present invention, a light detection sensor 64 for detecting whether a banknote is attached to the banknote contact surface of the main baffle 31 is installed on the back of the inclined portion 631 of the lower baffle 63, and a through hole for the light path of the light detection sensor 64 to pass through the main baffle 31 is provided on the main baffle 31, or the main baffle 31 is made of a transparent material. The beneficial effect of adopting the above technical solution is that it can timely detect whether there are banknotes remaining in the banknote collection space, and after detecting the existence of banknotes, the banknote falling flip plate and the baffle assembly can be driven by the banknote falling driving mechanism to repeatedly perform flipping actions to clean the remaining banknotes into the banknote collection space. If the existence of banknotes is still detected after multiple flipping and cleaning actions, an alarm prompt is issued, and manual inspection is carried out in time.

[0082] like Fig.11 , Fig.12 , Fig.14 As shown, in other embodiments of the present invention, multiple ribs 316 extending into the slot 326 at the lower end of the auxiliary baffle and multiple slots 317 accommodating the ribs 325 at the lower end of the auxiliary baffle are provided at intervals at the upper end of the main baffle 31. Multiple ribs 201 extending into the slot 315 at the lower end of the main baffle and multiple slots 202 accommodating the ribs 314 at the lower end of the main baffle are provided at intervals at the lower end of the banknote falling flap 20. The beneficial effect of adopting the above technical solution is that it can prevent banknotes from entering the interface gap between the two components and prevent banknotes from being stuck.

[0083] In other embodiments of the present invention, Fig.10 As shown, the banknote receiving impeller 10 includes two parallel and spaced impellers, and the impeller includes an impeller disc 11 and a plurality of blades 12 extending outwardly from the impeller disc. Fig.11 As shown, a blowing hole 203 is provided under each impeller on the banknote falling flip plate 20. Fig. 20 As shown, a slope block 74 is provided in the deposit device frame below the banknote receiving impeller 10, and guide boxes 70 that can move along the slope are respectively installed on the slope of the slope block 74 corresponding to the positions directly below the two impellers. The top surface of the guide box 70 has an arc surface that matches the outer contour of the impeller, and a plurality of concave semi-ellipsoidal air collecting grooves 71 are provided on the arc surface. The bottom of each air collecting groove 71 is collected to the air outlet pipe 73 through the air duct 72, and the mouth of the air outlet pipe 73 faces the blowing hole 203 of the banknote falling flap 20; when the banknote falling flap 20 swings down to the second angle position, the guide box 70 moves backward along the slope block and rises, so that the blades of each impeller of the banknote receiving impeller 10 contact the corresponding arc surface of the guide box ( Fig.21 After the banknote falling flap 20 is swung away from the second angle position, the guide box 70 moves forward along the inclined surface block 74 and descends, so that the blades of each impeller of the banknote receiving impeller 10 are separated from the corresponding arc surface of the guide box ( Fig. 22The beneficial effect of adopting the above technical solution is that after the banknote falling flap is flipped to the second angle position, the banknote receiving impeller rotates to scrape the banknote contact surface of the baffle assembly, while the blade contacts the arc surface of the guide box, which will generate airflow to the semi-ellipsoidal air collecting groove, and the airflow is guided to the blowing hole of the banknote falling flap through the air duct and the air outlet duct to blow out, which can blow off the residual banknotes that may be attached to the surface of the banknote falling flap, further ensuring that all banknotes can smoothly fall into the banknote collection container, and ensuring the accuracy of the amount of banknotes stored.
