Description

Technical Field

[0001] This utility model relates to a card dealing machine, specifically to a shuffling roller, a shuffling mechanism, and an integrated card dealing and shuffling machine. Background Technology

[0002] Miniature card dealers are typically used for home entertainment or small gatherings, making it easier for players to play while also increasing the fairness of the game. The prior art discloses a miniature card dealing machine, including a housing, a card compartment for holding playing cards, a card inlet located at the bottom front of the card compartment, a card feeding mechanism for feeding the playing cards from the card compartment to the card inlet, a card outlet located on the outside of the housing corresponding to the card inlet, a card dealing mechanism for dispensing the playing cards from the card inlet from the card outlet, and a rotating mechanism; the card feeding mechanism includes a first card feeding roller assembly located at the bottom inside the card compartment and near the front end of the playing cards, a second card feeding roller assembly located at the bottom inside the card compartment and near the rear end of the playing cards, a card feeding motor, and a first transmission assembly for transmitting the motor power to the first and second card feeding roller assemblies; the card dealing mechanism includes a card dispensing wheel assembly located below the card outlet, an elastic card pressing member located above the card outlet and pressing against the card dispensing wheel assembly, and a card dealing motor providing power to the card dispensing wheel assembly; the rotating mechanism includes a rotating base, which can rotate relative to the housing, thereby allowing the card dealing machine to deal cards in different directions. According to some publicly available alternative technical solutions, only one motor can be used to realize the functions of both the card-dealing motor and the card-feeding motor. In this implementation, the rotation of the card-feeding wheel and the card-pressing wheel is realized through transmission components such as a conveyor belt. Alternatively, only a set of card-feeding roller assemblies can be used. Furthermore, the structural forms of the elastic card-pressing component include, but are not limited to, elastic sheets, and the cooperative structure of the card-pressing wheel and spring. Existing card-dealing machines have batteries mounted on the left and right side walls of the housing, and the card-pressing function is achieved through a card-pressing rod.

[0003] CN2848304Y discloses an automatic card machine that integrates shuffling and dealing. During shuffling, a control circuit controls a motor, causing two dealing mechanisms located on both sides to deal cards alternately, thus completing the shuffling process. The shuffled cards then smoothly enter the dealing mechanism below for further dealing. The machine includes a turntable mounted on a central shaft at the base, driven by a motor and transmission gears. The control circuit is electrically connected to all motors. A dealing mechanism is mounted on the turntable, and a shuffling mechanism is located above it. The shuffling mechanism consists of two dealing mechanisms located on both sides. During shuffling, the control circuit controls the motor, causing the two dealing mechanisms on both sides to deal cards alternately, thus completing the shuffling process. The card-dealing mechanism consists of a card box, a card-feeding roller, an upper card-dispensing roller, a lower card-dispensing roller, a motor, and transmission gears. The card box has a card-feeding roller at its bottom and a card-dispensing opening on one side of the bottom. The upper and lower card-dispensing rollers rotate in the same direction, allowing only one card to pass through at a time. The cards, after shuffling, smoothly enter the card-dealing mechanism below. However, this shuffling mechanism is prone to card flying out. Using baffles to prevent this limits the usability of the cards, while adjustable baffles are cumbersome to operate, and the overall machine structure is complex and bulky, deviating from the original intention of this invention to design a miniature card machine. Furthermore, CN104023800B discloses a simple card shuffling device, comprising two card placement platforms for placing bundles of multiple cards to be shuffled; a shared card storage container for storing cards released from the two card placement platforms in one place; a first release mechanism and a second release mechanism, respectively disposed below the two card placement platforms for releasing cards one by one from the card placement platforms to the card storage container; a motor for driving the first release mechanism and the second release mechanism; and a control mechanism that causes the first release mechanism and the second release mechanism to selectively operate, selectively releasing cards from one of the two card placement platforms, storing the cards placed on the two card placement platforms in the shared card storage container, and shuffling multiple cards together.

[0004] The existing integrated card shuffling and dealing machine has problems such as multiple cards being dealt or cards getting stuck at the exit, which are not smooth during both shuffling and dealing. Utility Model Content

[0009] In some embodiments, a limiting component is provided at the card inlet, the limiting component constructing a limiting gap with variable height, the limiting gap being located behind the card splitting gap, the limiting gap being smaller than the card splitting gap in its natural state to prevent the card above the card to be issued from entering the card splitting gap, the driving force of the card feeding mechanism widening the limiting gap to drive the card to be issued through the limiting gap.

[0010] In some embodiments, the limiting component includes an axially floating limiting member disposed above the shuffling opening.

[0025] Please see Figures 1-3This embodiment provides an integrated card shuffling and dealing machine, which includes a mini card dealing machine 100 and a shuffling mechanism 200 for shuffling cards and feeding them into the mini card dealing machine 100. The shuffling mechanism 200 is mounted on the mini card dealing machine 100. The mini card dealing machine 100 includes a base 1, a housing 2, a card feeding mechanism, a card dealing mechanism, a rotary motor 3, at least one card dealing motor 5, and a power supply 6. The housing 2 defines an open card compartment 25, a card inlet 27 located at the front bottom of the card compartment 25, and a card outlet 26 located on the outside of the housing and corresponding to the card inlet. The top and rear of the card compartment 25 are open for placing cards. The card feeding mechanism is used to transport the cards from the card compartment 25 to the card inlet 27. The card dealing mechanism is located at the card outlet 26 to drive the cards from the card inlet 27 to be issued from the card outlet 26. The card dealing mechanism issues the cards from the card outlet 26 in a preset number. For example, playing cards are dispensed one at a time from the card dispensing port 26. A card dispensing motor 5 drives the card feeding mechanism and the card dispensing mechanism, and a rotary motor 3 drives the housing to rotate relative to the base. The power supply provides power to the card dispensing motor, the rotary motor, and the card shuffling mechanism. The card shuffling mechanism provided in this embodiment includes two placement platforms 10 and 11 for holding multiple playing cards, two dispensing mechanisms, and a control mechanism 201. The placement platforms 10 and 11 are mounted on the housing 2 of the miniature card dispenser, and a card dispensing channel is formed between the placement platforms 10 and 11 and the card storage 25. The card shuffling mechanism includes a top cover 13 covering the top opening of the card storage 25. Upper limiters 173 and 174 are mounted on the top cover 13. The gap between the top cover 13 and the two placement platforms 10 and 11 forms shuffling ports 101 and 111. The shuffling rollers and upper limiters are positioned at the shuffling ports to allow playing cards to enter the shuffling ports in a predetermined number, for example, one at a time. The upper limit members 173 and 174 have a limiting plate facing the shuffling roller, and the gap between the bottom of the limiting plate and the shuffling roller constitutes the shuffling gap.

[0026] The dispensing mechanism is located on the card dispensing channel to allow the cards to enter the shuffling port. The control mechanism 201 controls the actions of the two dispensing mechanisms to control the cards on the placement tables 10 and 11 to fall alternately into the hopper to complete the shuffling. The dispensing mechanism includes shuffling rollers 171 and 172, a shuffling motor, and upper limiters 173 and 174. The shuffling rollers 171 and 172 are located below the shuffling ports 101 and 111, and the upper limiters 173 and 174 are located above the shuffling ports 101 and 111.

[0027] In this embodiment, the card feeding mechanism includes at least one set of card feeding wheel assemblies, which are disposed on the bottom side of the card storage 25, thereby driving the cards in the card storage 25 forward. In some embodiments, a set of card feeding wheel assemblies 70 is disposed on the bottom side of the card storage 25. In other embodiments, a first card feeding wheel assembly and a second card feeding wheel assembly are disposed on the bottom side of the card storage 25, wherein the first card feeding wheel assembly is disposed behind the second card feeding wheel assembly to cooperate in completing the card feeding action. Exemplarily, the card feeding wheel assembly includes a rotating shaft and rollers, the rollers being rotatably mounted on the rotating shaft, which is driven by a card dealing motor.

[0028] The card-dealing mechanism drives the cards out of the card outlet 26. The mechanism includes at least one card-dealing wheel assembly 81 disposed below the card outlet 26 and at least one elastic card-pressing member 82 disposed above the card outlet 26. The card-dealing wheel assembly 81 includes a card-dealing wheel that rubs against the bottom of the cards to drive the cards out of the card outlet 26. The elastic card-pressing member 82 is disposed above the card-dealing wheel and cooperates with the card-dealing wheel assembly 81 to achieve smooth and uniform card dealing. In some embodiments, the card-dealing wheel assembly 81 includes a card-dealing shaft and a card-dealing wheel mounted on the shaft. In some embodiments, the elastic card-pressing member 82 can be selected from a floating card-pressing roller, an elastic pressure plate, etc. In this embodiment, the elastic card-pressing member 82 includes a card-pressing shaft mounted on the front housing 24 that can float up and down, a spring that provides reset power to the card-pressing shaft, and a card-pressing wheel mounted on the card-pressing shaft. The card-dealing motor 5 drives the card-feeding wheel assembly 70 and the card-dealing wheel assembly 81. Specifically, this may include two card-dealing motors 5, one of which outputs power to the card-feeding wheel assembly 70; the other card-dealing motor 5 provides power to the card-dealing wheel assembly 81. Alternatively, it may include only one card-dealing motor 5, using a synchronous belt to provide rotational power to the card-feeding wheel assembly 70 and the card-dealing wheel assembly 81; in this embodiment, only one card-dealing motor 5 is included, the card-dealing motor 5 drives the card-feeding wheel assembly 71 through a first synchronous belt, and the card-feeding wheel assembly 70 drives the card-dealing wheel assembly 81 through a second synchronous belt.

[0029] A rotary motor 3 drives the housing 2 to rotate relative to the base 1; the bottom side of the housing 2 has a rotating seat that rotates with the base 1. The housing 2 consists of a bottom shell 23, a left side wall 21, a right side wall 22, and a front shell 24: the bottom shell 23 includes a top cover 231 and a bottom plate 232, defining an installation space between the top cover 231 and the bottom plate 232, in which the rotary motor 3, the card-dealing motor 5, and the card-feeding wheel assembly are arranged; the top cover 231 has a clearance groove facing the card-feeding wheel assembly to allow the card-feeding wheel to extend and rub against the cards; the card-dealing motor 5 and the rotary motor 3 are installed in the installation space, and are centrally arranged in the left-right direction, with the card-dealing motor 5 and the rotary motor 3 positioned towards the rear. One side of the top surface is higher than the front top surface. The lower side of the top cover 231 abuts against the top of the card dealing motor 5 and the rotating motor 3. Thus, since the top surfaces of the card dealing motor 5 and the rotating motor 3 are not at the same height, they are staggered, and the top cover 231 forms an inclined surface 230 that extends downward from back to front. The left side wall 21 and the right side wall 22 are respectively connected to the left and right sides of the bottom shell 23. At least one of the left side wall 21 and the right side wall 22 is provided with a window 201. The front shell 24 is connected to the front side of the bottom shell 23, and the power supply 6 is installed in the front shell 24. Specifically, the card-dealing motor 5 and the rotary motor 3 are centrally positioned on the bottom side of the housing 2, with the top cover 231 abutting against them. This arrangement of the top cover, with its varying heights, creates a sloping surface 230 for holding the cards, preventing them from being thrown out through the rear opening of the housing 2 during the card-dealing process. Firstly, the staggered arrangement of the rotary motor 3 and the card-feeding motor supports the top cover 231, naturally forming the sloping surface 230, simplifying the inclined design of the housing 2's hopper and reducing the complexity of components such as pads. Secondly, this arrangement better distributes weight and lowers the center of gravity. Thirdly, the direct abutment of the top cover 231 against the tops of the rotary motor 3 and the card-dealing motor 5 reduces the possibility of the housing 2 and motors becoming loose, helping to reduce vibration and noise and improve the stability of the equipment during operation. Direct connection also reduces wear caused by friction, extending the equipment's lifespan and lowering maintenance costs. This rational arrangement minimizes wasted space in the lower part of the housing 2, allowing the front shell 24 of the housing 2 to house the power supply 6. This also enables the design of windows 201 on the left and right side walls 22 of the housing 2. The windows 201 allow players to view the card compartment 25 from all angles, enhancing transparency and ensuring fair dealing. This is especially important when the shuffling mechanism 200 is located at the top of the housing 2, making the windows 201 on the left and right side walls 22 even more crucial for fair dealing. Optionally, the dealing motor 5 and the rotating motor 3 are fixedly mounted on the base plate 232, with their tops abutting against the top cover 231. Limiting grooves, such as limiting edges, can be provided on the bottom side of the top cover 231 to further secure the dealing motor 5 and the rotating motor 3.

[0030] The card-dealing motor 5 is installed on the rear side of the installation space, the rotary motor 3 is installed in the middle of the installation space, and the power supply 6 is arranged in the front shell 24. That is, the card-dealing motor 5, the rotary motor 3, and the power supply 6 are arranged centrally from back to front, with uniform weight distribution and good stability when rotating and dealing cards. The inclination angle of the inclined surface 230 of the top cover 231 is 5°-10°, more preferably 6-9°; most preferably 7-8°; exemplarily, the inclination angle is 8°.

[0031] Furthermore, shuffling motors are installed on the left side wall 21 and the right side wall 22.

[0032] Please see Figure 3 The card dealing machine includes a limiting mechanism for restricting the number of cards entering the card inlet. The limiting mechanism includes a lower limiting block 271 and an upper limiting block 272. The upper limiting block 272 and the lower limiting block 271 are respectively located on the bottom and top sides of the card inlet 27. The card-separating gap formed between the upper limiting block 272 and the lower limiting block 271 allows single cards to enter the card inlet. The lower limiting block and the card-feeding wheel assembly form a conveying channel for transporting the cards. The lower limiting block is fixed to the bottom shell, and a front clearance opening is formed on the front side of the top cover for the lower limiting block to extend. The top of the lower limiting block forms an inclined surface with the same inclination angle as the top cover, facilitating the smooth entry of cards into the card inlet and preventing jamming or blockage. Furthermore, because the lower limiting block is fixedly installed on the bottom shell, it is not easily loosened, and its smooth top surface prevents frictional damage to the cards.

[0033] In some embodiments of this utility model, the structure of the shuffling rollers is improved. Since the shuffling rollers 171 and 172 are correspondingly arranged with the upper limit members 173 and 174, and since the structures of shuffling rollers 171 and 172 are identical, the following description will only use shuffling roller 171 as an example. Please refer to... Figure 4The shuffling roller 171 includes a roller body 1710 and six equally spaced protrusions 1711 on the roller body. The protrusions 1711 extend longitudinally along the length of the roller body. The protrusions 1711 and the upper limit stop form a card-feeding gap, limiting the cards to enter the card compartment at a specific dealing speed. The roller body stably transports the cards to the shuffling opening. When the protrusions 1711 rotate below the upper limit stop 173, they roll the cards into the card compartment. With only the roller body 1710, the cards enter the card compartment 25 by gravity and sliding friction, resulting in uneven or jammed card descent. However, the roller with the protrusions 1711, through its undulating shape and structure, can roll the cards into the card compartment during rotation. This rolling mechanism, through the edge shape of the protrusions and the physical contact during rotation, actively guides the cards in, preventing them from falling directly. The shape and design of the raised strips can stabilize the card transport path, reduce card shaking and deviation during transport, and because its design can effectively guide and control the cards to enter, the overall shuffling speed will be faster, reducing wasted time.

[0034] The six raised strips 1711 provide more contact points, simultaneously engaging with the cards. This gives the cards a greater chance to be caught and guided by the rollers during loading, enabling them to be efficiently and quickly rolled into the card magazine. Since each strip both supports the card and helps guide its path into the magazine, the six strips work together more effectively, facilitating faster loading of the cards.

[0035] In some embodiments of this invention, the shuffling process of playing cards is improved; please refer to [link / reference needed]. Figure 1-3 , Figure 5 The top cover 13, facing the card compartment, has a movable guide section 131. This guide section guides multiple cards emitted from the shuffling port into the card compartment alternately. The guide section 131 includes a left guide surface 1311 and a right guide surface 1312, which guide the left and right cards from the shuffling port smoothly into the card compartment along a predetermined path, respectively. To prevent the cards from colliding head-on during entry, both the left and right guide surfaces are designed as slopes to utilize gravity and the center of gravity to improve the sliding efficiency of the cards.

[0036] The guide section 131, hinged to the top cover, is swayable left and right. When a card approaches the guide section 131, its flexible movement allows it to adjust its angle in real time, ensuring the card's descent always points towards the corresponding guide surface, further reducing the possibility of card collisions. Specifically, when a card on the left contacts the left guide surface, the guide section sways to the right, allowing a card on the right to smoothly contact the right guide surface and slide into the compartment along a predetermined path. This structure not only provides necessary support and guidance for the cards but also effectively avoids collisions caused by inaccurate card alignment. Through the guide section of this invention, the card processing system achieves higher efficiency and stability during operation, reducing downtime caused by card collisions and thus improving overall work efficiency. The transition point 1313 between the left and right guide surfaces is an arc-shaped surface.

[0037] In some embodiments of this utility model, due to the inclined arrangement of the card compartment, the upper card of the card to be dealt can easily slide to the card inlet, thus affecting the smooth dealing of the bottom card. Therefore, a limiting component is provided at the card inlet 27 to prevent the upper card of the card to be dealt from entering the card inlet 27. Here, "card to be dealt" refers to the card whose bottom part directly rubs against the card feeding wheel assembly 70, i.e., the bottommost card. The limiting gap is located behind the card separation gap. In its natural state, the limiting gap is smaller than the card separation gap to prevent the upper card of the card to be dealt from entering the card separation gap. The limiting gap is smaller than the thickness of a single card. This includes the case where the limiting gap is 0, and the driving force of the card feeding mechanism widens the limiting gap to drive the card to be dealt through the limiting gap. The limiting gap is at its narrowest state in its natural state. In this way, as the bottom card is conveyed towards the card inlet by the card delivery wheel assembly, the limiting gap widens, allowing the bottom card to enter the card inlet and be sent out through the card outlet. The bottoms of the cards above the second-to-last card are not in contact with the card delivery wheel and are therefore confined within the limiting gap. This prevents the cards above from moving forward to the card inlet due to gravity, thus avoiding the bottom card from being difficult to send out. Because the bottom of the second-to-last card is confined within the limiting gap, under the influence of gravity and other external forces, only the bottom card can move smoothly with the card delivery wheel, ensuring the order and stability of the card dealing. This ensures that the bottom card is accurately and undisturbed when entering the card outlet, without being affected by the position of the cards above, reducing congestion and jamming. Furthermore, due to the existence of the limiting gap, the last few cards are at the top of the stack during the card dealing process, experiencing less gravitational pressure, making them easier to float or move forward. The variable limit gap of the limiting component allows the last few cards to move smoothly toward the card slot.

[0038] Please see Figure 1 , Figure 3 The limiting component includes a limiting member 9 that can float or deform axially. The limiting member is located at the card inlet and can move or deform axially when subjected to the card conveying force to define an expanded limiting gap. Further, the limiting member 9 is located above the card inlet and can move upwards when subjected to the card conveying force, thereby forming a variable limiting gap. In its natural state, the limiting member blocks the upper card from moving forward, and can move upwards when pushed by the card conveying force. In this embodiment, the limiting member 9 cooperates with the lower limiting block of the limiting mechanism, forming a limiting gap between them. Further, in its natural state, the lower end of the limiting member directly contacts the lower limiting block without gap. It is understood that a separate lower limiting block can be provided, as long as it creates the limiting gap before the card separation gap.

[0039] Exemplarily, the housing 2 is provided with a sliding cavity 90 for the axial floating of the limiting member 9. The end of the limiting member 9 facing the card compartment is an arc-shaped portion 91, a conical portion, or an inclined surface. Specifically, the limiting member is a ball bearing or a suspended needle. In this embodiment, please refer to... Figure 6 The limiting member includes a cylindrical portion 91 and an arc-shaped portion 92, with the arc-shaped portion located at the head end of the cylindrical portion. Exemplarily, the limiting member is positioned above the lower limiting block, and the lower end of the limiting member directly contacts the lower limiting block without gap.

[0040] Example 2

[0041] Please see Figure 7This embodiment provides a miniature card dealer. A rotary motor 3 drives a housing 2 to rotate relative to a base 1. The output shaft of the rotary motor 3 drives the housing to rotate via a transmission assembly. This transmission assembly includes a drive wheel set, a driven wheel set, and at least one shock-absorbing component. At least one set of the drive wheel set and the driven wheel set is fitted with a shock-absorbing component to effectively reduce vibration and noise generated when the card dealer is running or stopped. The drive wheel set includes at least one drive wheel (e.g., one), and the driven wheel set includes at least one driven wheel 6 (e.g., one). The drive wheel set and the driven wheel set are connected in a transmission connection. When the card dealer starts or stops, the drive wheel, due to inertia, will drive the driven wheel to rotate. If the driven wheel is rigidly connected to the base, it will cause vibration and noise in the base. Therefore, the driven wheel set is flexibly connected to the base. This flexible connection means that the driven wheel is allowed to rotate slightly relative to the base. Thus, the driven wheel set can move slightly relative to the base 1, reducing vibration and noise caused by the rigid connection. Furthermore, to reduce the inertial motion of the driven wheel assembly, the transmission component also includes at least one elastic reset member, which is disposed between the driven wheel assembly and the base. Exemplarily, the elastic reset member is a spring; when the motor starts, the elastic reset member provides a buffering effect, absorbing the instantaneous impact force brought about by the motor startup. By reducing the impact between the driving and driven wheels, the elastic reset member reduces the impact force transmitted to other mechanical components, thereby effectively reducing the vibration and shaking of the entire system.

[0042] Furthermore, the elastic reset component continues to function during motor operation. When the motor stops, the inertia of the driving wheel causes vibration in the driven wheel. The elastic reset component can quickly pull the driven wheel back, using its restoring force to prevent continuous vibration caused by inertial motion, thereby ensuring the stability and reliability of the card dealing machine.

[0043] In summary, the elastic reset element provides a buffering effect for motor start-up and shutdown, improving operational smoothness, extending equipment lifespan, and reducing maintenance costs. This design effectively enhances the stability and efficiency of the mini card dealer.

[0044] The system's influence makes the mini card dealer exhibit higher stability and efficiency in actual operation.

[0045] Based on this, the transmission assembly provided in this embodiment also includes a shock absorber 612, which is sleeved between the driven wheel assembly and the base 1. The shock absorber 612 provides a mechanism for buffering and absorbing energy. When the driven wheel 6 attempts to pull back due to inertial motion, the shock absorber can limit the magnitude of this pullback. The shock absorber is typically made of an elastic material, such as rubber or polymer, and its design allows it to deform under force and effectively absorb energy when the reverse pressure is released, producing a delaying and mitigating effect. In addition, the shock absorber 612 can effectively dampen the vibration generated at the moment the motor starts and stops. By reducing vibration, the shock absorber 612 can also reduce the noise generated by the card dealer during operation, thereby creating a quieter environment and improving the user experience.

[0046] The transmission assembly is mounted on the base. The drive wheel assembly includes a drive wheel, and the driven wheel assembly includes a driven wheel. The output shaft of the rotary motor is connected to the drive wheel. The drive wheel and the transmission wheel are connected by a belt, chain, or meshing transmission. The shock-absorbing rubber ring is fitted between the driven wheel and the base to reduce the vibration caused by the inertial rotation of the driven wheel after the machine stops.

[0047] Specifically, optionally, the shock-absorbing part 612 is a shock-absorbing ring, which is an elastic ring, specifically a shock-absorbing rubber ring. The inner ring of the shock-absorbing ring is in frictional contact with the driven wheel, and the outer ring is in frictional contact with the base. During normal operation of the equipment, the output shaft of the rotary motor 3 rotates with the driving wheel, which is connected to the driven wheel 6 via a belt, keeping the driven wheel stationary relative to the driving wheel. When the rotary motor starts and stops, the belt drives the driven wheel to undergo inertial motion. At this time, the shock-absorbing rubber ring mounted on the driven wheel effectively absorbs the kinetic energy caused by inertia, thereby reducing vibration and noise after starting and stopping.

[0048] In this embodiment, the driven wheel is flexibly positioned at the center of the base, which facilitates a more even load distribution. This means that during operation, the rotation of the housing can be more stable, reducing tilting and vibration caused by an unstable center of gravity. In this embodiment, the driven wheel is fitted with a shock-absorbing rubber ring.

[0049] To achieve a flexible connection between the driven wheel and the base, the following structure can be implemented: The driven wheel 6 includes a driven wheel body 61 and a connecting part 62. The connecting part 62 is disposed on the driven wheel body 61, and the driven wheel body 61 is in a driving engagement with the driving wheel 62. The shock-absorbing part 612 is disposed between the connecting part 62 and the base 1, and the connecting part 62 is flexibly connected to the base. In some embodiments, the connecting part 62 is rotatably connected to the base 1, wherein the base 62 is provided with a limiting groove to restrict the rotation amplitude of the connecting part. For example, the base is provided with at least two arc-shaped limiting grooves circumferentially, and the connecting part is provided with a limiting part (limiting rod, etc.) that rotatably engages with the limiting groove. The limiting part is slidably disposed in the limiting groove so that the driven wheel is flexibly connected to the base.

[0050] Furthermore, the belt is tensioned on the driving pulley and the driven pulley, and a mounting cavity is defined between the base and the driven pulley, with the shock-absorbing ring clamped in the mounting cavity. Specifically, the base has a circumferential cavity 611, the connecting part 62 has a circumferential outer wall 620, and a shock-absorbing rubber ring 612 is disposed between the circumferential outer wall 620 and the inner wall of the circumferential cavity 611.

[0051] The base 1 is provided with a limiting groove, and the connecting part is provided with a limiting part that rotates with the limiting groove. The bottom of the connecting part forms a limiting step 621 that restricts the axial movement of the driven wheel. The limiting step 621 is locked on the bottom outer side of the base to restrict the vertical displacement of the driven wheel. The cooperation between the limiting groove and the limiting part restricts the circumferential rotation of the driven wheel, ensuring that it cooperates with the driving wheel while avoiding excessive machine noise and vibration caused by rigid connection.

[0052] It is understood that the shock-absorbing part provided in this embodiment can also be applied to the shampoo and hair styling machine provided in Embodiment 1 of this embodiment.
