[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0032] It should be noted that all the directionality indications (such as up, down, left, right, front, back, etc.) in the embodiments of the utility model are only used to explain the relative position relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directionality indications also change accordingly.

[0033] The main purpose of the utility model is to provide a coin outlet device 100 to solve the low coin outlet efficiency problem in the prior art.

[0034] Referring to Figures 1 to 8 In an embodiment of the utility model, a coin outlet device 100 comprises a base 110, a rotating disc 120 and a coin ejector 130. The top surface of the base 110 is inclined, and the lowest point of the top surface of the base 110 is provided with a coin outlet 110a. The rotating disc 120 is provided in a gap with the top surface of the base 110 and can rotate relative to the base 110. The rotating disc 120 is provided with a plurality of coin outlets 120a, and the plurality of coin outlets 120a are arranged around the center of the rotating disc 120. The surface of the rotating disc 120 facing the base 110 is integrally formed with a plurality of guide arms 121. The plurality of guide arms 121 are arranged at intervals around the rotating disc 120. The guide arms 121 extend from the edge of the rotating disc 120 to the center of the rotating disc 120 and are tangent to the outer diameter of the coin outlets 120a. The adjacent guide arms 121 form an arc-shaped channel 121a. When the rotating disc 120 rotates, the coins enter the arc-shaped channel 121a from the coin outlets 120a under the centrifugal force of the rotating disc 120. The coin ejector 130 is arranged close to the coin outlet 110a on the base 110. When the rotating disc 120 rotates, the coins in the arc-shaped channel 121a hit the coin ejector 130 and are ejected from the coin outlet 110a.

[0035] In the technical solution of this utility model, the top surface of the base 110 is inclined, and the coin outlet 110a is located at the lowest point of the inclined surface; the turntable 120 is spaced on the top surface of the base 110, and the turntable 120 is provided with multiple coin outlets 120a and integrally formed with multiple guide arms 121. The multiple guide arms 121 are arranged at intervals around the turntable 120, and the guide arms 121 extend from the edge of the turntable 120 to the center of the turntable 120 and are tangent to the outer diameter of the coin outlets 120a. An arc-shaped channel 121a is formed between adjacent guide arms 121; the coin ejection device 130 is located near the coin outlet 110a; when the turntable 120 rotates, the coin enters the coin outlet 110a from the surface of the turntable 120, then enters the arc-shaped channel 121a from the coin outlet 110a, and finally is ejected from the coin outlet 110a by the coin ejection device 130. Because the turntable 120 is tilted, the coins will naturally slide to the lowest point due to their own weight when rotating to dispense coins. Combined with the centrifugal force generated during rotation, the coins can be ejected from the coin outlet 110a more quickly, making the coin dispensing process more stable and faster. In addition, since the turntable 120 is integrally formed with a guide arm 121, the guide arm 121 and the turntable 120 can move synchronously. High-speed coin dispensing can be achieved without the need for coordination adjustment between the two. The guide arm 121 can deliver the coins that have entered the coin outlet 120a to the coin outlet 110a more quickly, avoiding coin accumulation while ensuring a high coin dispensing rate.

[0036] It should be noted that the turntable 120 is tilted at a certain angle, and the coin outlet 110a is located at the lowest point of the slope. The principle is to fully utilize the coin's own weight and the centrifugal force generated during rotation to allow the coin to fall into the coin outlet 110a more quickly. Furthermore, to prevent coin blockage, a coin guide ramp 113 extends outward from the coin outlet 110a and is surrounded by a sheet metal part to form an exit, allowing the coin to slide out smoothly. Compared with turntables 120 of the same size on the market, the turntable 120 of this application has more coin outlets 120a. The coin outlets 120a are evenly distributed around the center of the turntable 120, allowing more coins to enter the turntable 120 in the same amount of time to achieve a fast coin dispensing effect. Of course, in some other embodiments, the coin outlets 120a can also be arranged in other ways, such as a matrix or irregularly arranged around the center of the turntable 120, which is not limited here. The number of coin outlets 120a is determined by the following formula: Where 'a' represents the number of coin dispensing holes, 'D' represents the diameter of the turntable, and 'd' represents the diameter of the coin dispensing holes. The number of coin dispensing holes in the formula is rounded down. The coin dispensing hole 120a is designed in a funnel shape, wider at the top and narrower at the bottom. This design makes it easier for coins to enter the coin dispensing hole 120a, while also limiting the coin's movement and guiding it to the arc-shaped channel 121a after entry, improving the stability and speed of coin dispensing. Multiple guide arms 121 are integrally formed on the back of the turntable 120, from... Figure 6As can be seen, a portion of the arc of the guide arm 121 is tangentially fitted to the outer diameter of the coin outlet 120a. The guide arm 121 replaces the flying knife disc in the prior art, ensuring that the coin can be accurately pushed towards the coin ejector 130 and ejected from the coin outlet 110a by the coin ejector 130. It can be understood that since the turntable 120 is set on the top surface of the base 110 with a gap slightly larger than the thickness of the coin, by protruding the guide arm 121 on the surface of the turntable 120, the coin will be limited by the arc-shaped channel 121a after falling into the inclined turntable 120 and will not fall out of the turntable 120. Only when the turntable 120 rotates to the coin outlet 110a will the coin be ejected from the coin outlet 110a by the coin ejector 130 through the arc-shaped channel 121a due to the downward potential energy of centrifugal force. Preferably, the turntable 120 is integrally formed from die-cast steel, which has high rigidity and strength to ensure the stability of the turntable 120 during high-speed rotation. Of course, in other embodiments, the turntable 120 can also be made of stainless steel, plastic, or other materials, which are not limited here. Furthermore, a high-speed motor 160 is provided below the base 110. The high-speed motor 160 has a rotation speed of 100 rpm and has forward and reverse rotation functions. The high-speed motor 160 is connected to a drive shaft protruding from the top surface of the base 110. The turntable 120 is inserted into the drive shaft, and the drive shaft drives the turntable 120 to rotate at high speed, so that more coins can quickly enter the coin dispensing hole 120a, ensuring that the coin dispensing device 100 has a high coin dispensing rate. It is understood that the high-speed coin dispensing effect of this application is achieved through the synergy of the aforementioned features. A single method cannot achieve the same effect. For example, simply increasing the number of coin dispensing holes 120a on the turntable 120 without quickly feeding coins into the holes 120a would only result in wasted coin dispensing holes 120a and would not achieve high-speed coin dispensing. The coin dispensing device 100 of this application can achieve a coin dispensing efficiency of 1300 coins / minute.

[0037] When the coin dispensing device 100 of this application is applied to a coin dispensing machine, a coin dispensing device 100 is installed inside the machine's casing. After a sufficient number of coins are manually pre-deposited, the coins are sent to a turntable via a conveyor mechanism inside the casing. The turntable rotates forward to start dispensing coins. Furthermore, the turntable 120 has a reverse error correction function. When the forward dispensing fails to count coins, the turntable 120 reverses to restore the coin dispensing device 100 to its original normal state, preventing the coin dispensing machine from being in an incorrect dispensing process and causing further malfunctions. With only one coin dispensing device 100 of this application, the coin dispensing efficiency of the coin dispensing machine can reach 1300 coins / minute, while the coin dispensing efficiency of existing coin dispensing machines using a single device is only 600 coins / minute. To improve the coin dispensing efficiency, two devices need to be set up to dispense coins simultaneously. The coin dispensing speed of this application is more than twice that of coin dispensing devices 100 on the market.

[0038] See Figures 1 to 8Furthermore, in one embodiment of this utility model, a first blocking member 111 and a second blocking member 112 are provided on the base 110 at intervals. At least a portion of the first blocking member 111 and the second blocking member 112 protrudes from the top surface of the base 110. The first blocking member 111 and the second blocking member 112 are disposed near the coin ejector device 130 and located on the active stroke of the coin outlet hole 120a. When the turntable 120 rotates forward, the first blocking member 111 pushes the coin in the coin outlet hole 120a toward the coin ejector device 130. When the turntable 120 rotates in reverse, the second blocking member 112 pushes the coin in the coin outlet hole 120a out of the coin outlet hole 120a.

[0039] Specifically, both the first blocking member 111 and the second blocking member 112 are preferably in the form of pins. The first blocking member 111 and the second blocking member 112 are positioned close to the coin outlet 110a, spaced apart and both located along the travel of the coin outlet 120a. One end of each blocking member protrudes from the top surface of the base 110, and the height of the protruding portion is less than the gap between the turntable 120 and the base 110. (See also...) Figure 6 It is understandable that, to prevent the guide arm 121 from colliding with the blocking components during the rotation of the turntable 120, the middle of the guide arm 121 is divided into two gaps to avoid interference between the first blocking component 111 and the second blocking component 112. Clockwise rotation of the turntable 120 is considered forward rotation, and counterclockwise rotation is considered reverse rotation. Figures 1 to 4As can be seen, according to the movement trajectory of the turntable 120, the first blocking member 111 and the second blocking member 112 have sequential positions. In this embodiment, when the turntable 120 rotates clockwise, the coin will only contact the first blocking member 111, and when it rotates counterclockwise, the coin will only contact the second blocking member 112. Therefore, when the turntable 120 rotates clockwise to dispense the coin, the coin enters the coin outlet 120a and is carried to the vicinity of the coin outlet 110a by the arc-shaped channel 121a. As the turntable 120 continues to rotate, it will carry the coin and collide with the first blocking member 111. Due to the interaction of forces and the centrifugal force generated during rotation, the coin is struck by the first blocking member 111 against the coin ejector 130, thereby guiding the coin more accurately and quickly to the coin outlet 110a and improving coin dispensing efficiency. When the turntable 120 reverses, the coin in the coin outlet 120a strikes the second blocking member 112 and is ejected from the coin outlet 120a. This coin-jumping action removes stuck coins, preventing them from jamming the coin dispensing device 100 and avoiding further malfunctions caused by the coin dispenser being stuck in an incorrect dispensing process. It should be noted that the blocking member can also take other forms, such as protrusions, wave-shaped protrusions, headless screws, etc. The number and position of the blocking members can also be adjusted according to factors such as the size of the turntable 120, the rotation rules of the turntable 120, and the size of the coin, as long as it can guide the coin to the coin outlet 110a and / or eject it from the coin outlet 120a during rotation. This embodiment of the utility model is not limited to these, and all of the above are within the protection scope of this utility model.

[0040] See Figures 1 to 8 Furthermore, in one embodiment of this utility model, the first blocking member 111 and the second blocking member 112 are rotatably disposed on the base 110. The ends of the first blocking member 111 and the second blocking member 112 protruding from the top surface of the base 110 form two opposing inclined surfaces. Specifically, the first blocking member 111 and the second blocking member 112 are rotatably disposed on the base 110 in the form of pins. The ends of the two blocking members protruding from the base 110 have two opposing inclined surfaces. The inclined surfaces extend from the middle of the top of the pin to both sides. In use, the direction of the inclined surfaces is adjusted by rotating the pin, so that the inclined surfaces face the movement trajectory line of the coin outlet 120a. With this configuration, when a coin hits the first blocking member 111 and / or the second blocking member 112, the inclined surfaces can act as a guide and buffer, preventing scratches on the coin and better guiding the coin to the coin ejector device 130 or ejecting it from the coin outlet 120a.

[0041] See Figures 1 to 8Furthermore, in one embodiment of this utility model, a protrusion 122 is provided on the side of the turntable 120 facing away from the base 110, and multiple coin outlet holes 120a are arranged around the protrusion 122. The side of the protrusion 122 guides the coin outlet holes 120a, and the side inclination of the protrusion 122 is 10° to 30°. By providing the protrusion 122, coins resting on the turntable 120 can slide along the side of the protrusion 122 into each coin outlet hole 120a, avoiding coins from remaining on the surface of the turntable 120 for too long, causing coin accumulation and coin jamming. Preferably, the boss 122 and the turntable 120 are integrally formed. The side inclination of the boss 122 is 10° to 30°. The integrated design reduces the number of connection points between the boss 122 and the turntable 120, making the connection smoother. It also avoids the situation where a split structure suffers from poor guiding performance due to insufficient installation precision. Regarding the inclination angle of the boss 122, testing has shown that this range of angles provides the best guiding effect for the coin. Regardless of the angle from which the coin enters the turntable 120, it can slide through the inclined surface of the boss 122 into the coin outlet 120a. It should be noted that the inclination angle of the boss 122 can be set to other angles depending on the size of the turntable 120, the size of the boss 122, and the size of the coin, depending on the actual situation. In addition to the boss 122, structures with a certain slope, such as a hemisphere, can also be provided, as long as they can guide the coin out of the coin outlet 120a. This embodiment of the invention is not limited to these, and all of the above are within the protection scope of this invention.

[0042] See Figures 1 to 8 Furthermore, in one embodiment of this utility model, the side surface of the boss 122 is provided with a plurality of guide grooves 122a corresponding to the coin outlet 120a. The guide grooves 122a extend from the top surface of the boss 122 towards the outer diameter of the coin outlet 120a, and a raised ridge is formed between adjacent guide grooves 122a. The guide grooves 122a are used to guide the coin to the coin outlet 120a. Specifically, according to the number of coin outlets 120a, the side surface of the boss 122 is formed with a corresponding number of guide grooves 122a by precision milling. The cross-section of the guide grooves 122a is U-shaped, so that the connection between adjacent guide grooves 122a forms a unique raised ridge structure. Each guide groove 122a extends from the top surface of the boss 122 towards the outer diameter of the coin outlet 120a. It can be understood that its cross-sectional area gradually increases from the top surface to the bottom surface of the boss 122, so that the guide grooves 122a are adapted to the size of the coin. This design has two advantages. First, by providing a corresponding guide groove 122a for each coin outlet 120a, and ensuring that the shape of the guide groove 122a conforms to the shape of the coin, the coin can slide into the coin outlet 120a more easily when the turntable 120 rotates. Second, the protruding ridges ensure that the coin can be guided into the coin outlet 120a no matter where it is on the surface of the turntable 120 when it rotates, thus improving coin dispensing efficiency.

[0043] See Figures 1 to 8 Furthermore, in one embodiment of this utility model, on the side of the turntable 120 facing away from the base 110, a conical protrusion 123 is provided between adjacent coin outlet holes 120a, and the conical surface of the conical protrusion 123 guides the coin outlet hole 120a. Specifically, the conical protrusion 123 is equidistantly arranged around the center of the turntable 120 at the edge of the turntable 120 and is located in the gap between pairs of coin outlet holes 120a. It can be understood that when the turntable 120 rotates, coins thrown to the edge of the turntable 120 by centrifugal force will slide into either of the coin outlet holes 120a on either side of the conical protrusion 123. This ensures that coins do not accumulate at the edge during the rotation of the turntable 120, causing coin jamming, and at the same time allows coins to quickly enter the coin outlet hole 120a, ensuring coin dispensing efficiency.

[0044] See Figures 1 to 8 Furthermore, in one embodiment of this utility model, a plurality of foreign object holes 110b are provided on the top surface of the base 110. These holes 110b are located on the central trajectory line of the plurality of coin outlet holes 120a, and the outer diameter of each hole 110b is smaller than the outer diameter of the coin. Specifically, along the central trajectory line of the plurality of coin outlet holes 120a, six circular foreign object holes 110b are provided on the top surface of the base 110, respectively located on both sides of the central axis of the turntable 120. When the turntable 120 is running, small foreign objects may enter the turntable 120. By providing the foreign object holes 110b, these objects will fall into the holes 110b and be discharged when the turntable 120 rotates, preventing coin jamming, machine jamming, and other phenomena caused by foreign objects. Preferably, the foreign object holes 110b are all located close to the coin outlet 110a, and the top surface of the base 110 is inclined at a certain angle. Foreign objects will move towards the lower part of the inclined surface, making it easier for foreign objects to enter the foreign object holes 110b. It should be noted that the shape of the foreign object holes 110b can be other than a round hole, such as a rectangle, triangle, or other irregular polygons, as long as it allows foreign objects to fall and ensures that coins cannot pass through. The number of foreign object holes 110b can also be determined according to the actual situation. This embodiment of the utility model is not limited to this, and all of the above are within the protection scope of this utility model.

[0045] See Figures 1 to 8Furthermore, in one embodiment of this utility model, the coin ejection device 130 includes a movable roller 131, a fixed roller 132, and an elastic element. The movable roller 131 and the fixed roller 132 are spaced apart on the base 110. The movable roller 131 is connected to the elastic element. The movable roller 131 moves closer to or further away from the fixed roller 132 through the elastic element to eject coins that collide with the movable roller 131 out of the coin outlet 110a. Specifically, an arc-shaped groove is formed on the top surface of the base 110 near the coin outlet 110a. The movable roller 131 is movably disposed in the arc-shaped groove. The fixed roller 132 is spaced apart from the movable roller 131, forming a narrow passage between them for coins to pass through. It can be understood that the width of the narrow passage can be adjusted by adjusting the position of the movable roller 131 in the arc-shaped groove to accommodate coins of different sizes. The bottom end of the movable roller 131 is connected to an elastic element. In this embodiment, the elastic element is preferably a torsion spring structure (not shown in the figure). In use, when a coin rotates with the turntable 120 and hits the movable roller 131, the movable roller 131 moves away from the fixed roller 132 due to the force, compressing the torsion spring. Then, the force generated by the torsion spring returning to its original position pushes the movable roller 131 back to its original position, and the coin passes through the slit and is ejected from the coin slot 110a. It should be noted that the elastic element can also take other forms, such as a spring sheet, an elastic pin, an elastic ring, a spring, etc. This embodiment of the utility model is not limited to these, and all of the above are within the protection scope of this utility model.

[0046] See Figures 1 to 8 Furthermore, in one embodiment of this utility model, a coin hopper 140 is included, which is connected to a base 110. The inner cavity of the coin hopper 140 surrounds a turntable 120. A ramp is provided in the inner cavity of the coin hopper 140, which guides the turntable 120. A plurality of protrusions 141 are provided at intervals along the transverse direction of the ramp. By incorporating a ramp within the coin hopper 140, the coins falling into the hopper are cushioned, giving the hopper 140 a certain degree of pressure resistance. This prevents a large number of coins from simultaneously exerting their weight on the turntable 120, which could cause excessive pressure on the turntable 120 and affect the stability of the device. Testing has shown that the coin hopper 140 of this application can withstand a weight of 160 kg, approximately equivalent to 20,000 coins. This indicates that the coin hopper 140 can withstand a sufficient number of coins to meet high-speed coin dispensing efficiency while reducing the frequency of manual coin addition. Preferably, multiple raised strips 141 are spaced apart on the surface of the ramp, increasing the friction between the coins and the ramp surface, preventing a large influx of coins in a short period, further enhancing the pressure resistance of the coin hopper 140. The raised strips 141 also serve as guides for coin sliding. It should be noted that even without the raised strips 141 on the ramp, the coin hopper 140 still possesses a certain degree of pressure resistance.

[0047] See Figures 1 to 8Furthermore, in one embodiment of this utility model, a coin presser 150 is included. The coin presser 150 is disposed above the coin outlet 120a and is used to guide coins from the surface of the turntable 120 into the coin outlet 120a. Specifically, the coin presser 150 is a plastic or metal rod, which is disposed on the inner wall of the coin hopper 140 via a connector. Preferably, it is disposed above the coin outlet 120a, which is closest to the coin outlet 110a. The position of the coin presser 150 can be adjusted by adjusting the connector so that the coin presser 150 is directly facing and as close as possible to the coin outlet 120a. When there are few coins in the turntable 120, the coins will stand upright due to centrifugal force, making it difficult for them to enter the coin outlet 120a. By setting a coin presser 150 to apply force to the coins in this state, they will fall down and smoothly enter the coin outlet 120a. In this way, even if only one coin remains in the turntable 120, it can still be delivered. In addition, when there are many coins, the coin presser 150 can also apply appropriate pressure to the rotating coins to make them quickly enter the coin outlet 120a, shortening the time the coins stay on the turntable 120 and achieving the effect of fast coin delivery. It should be noted that the coin presser 150 can also take other forms, and its installation position can be reasonably set in other positions of the coin hopper 140 or directly connected to the base 110 through a connector, as long as it can guide the coins into the coin outlet 120a. This utility model embodiment is not limited to this, and all of the above are within the protection scope of this utility model embodiment.
