Description

Technical Field

[0001] This utility model relates to the field of card machine technology, specifically to a rotating mechanism and an automatic card machine. Background Technology

[0002] Rotary mechanisms are widely used in industrial automation equipment, smart home devices, and entertainment facilities, such as automatic card machines. In existing technologies, the design of rotary mechanisms in automatic card machines typically faces the following problems: During operation, the internal components of the rotary mechanism in traditional automatic card machines experience impacts during start-up and shutdown, and severe vibrations and noise can occur due to inertia or load changes. This results in poor stability and, with prolonged use, mechanical wear, reducing the equipment's lifespan. Utility Model Content

[0003] This invention provides a rotating mechanism and an automatic card machine, which can overcome some or all the defects of the prior art.

[0004] According to the present invention, a rotating mechanism includes: a transmission component for rotatably engaging with an object to be rotated;

[0005] A power assembly fixedly installed at the object to be rotated, which is used to drive the object to be rotated to rotate relative to the transmission component;

[0006] A support member, which supports a transmission component and has a circumferentially mating stroke with the transmission component; and

[0007] A damping element is used to achieve indirect contact between the transmission element and the support element, and to provide resistance when the transmission element and the support element rotate relative to each other at the mating stroke.

[0008] Through this invention, the rotating mechanism achieves active and controllable rotation of the object to be rotated by rotatable engagement between the transmission component and the object to be rotated, combined with the power component fixed to the object. The circumferential engagement stroke design between the support component and the transmission component allows the transmission component to rotate relative to the support component within a certain angle range. The indirect contact design of the damping component provides resistance during relative rotation, effectively buffering the impact during rotation and the start-stop phase, reducing mechanical vibration and noise, and improving the stability and service life of the rotating mechanism.

[0009] Preferably, the transmission component and the support component have an initial mating position at the mating stroke. The rotating mechanism also includes a reset component, which is used to reset the transmission component and the support component to the initial mating position.

[0010] With this invention, the transmission component and the support component have an initial mating position at the mating stroke. The transmission component and the support component can achieve relative rotation within a certain range at the mating stroke. The reset component enables the transmission component and the support component to automatically return to the initial mating position after completing the relative rotation, ensuring the accuracy and consistency of the mechanism's repetitive actions. It is suitable for the periodic rotation and return of automatic card machines.

[0011] Preferably, the power assembly includes a motor with a rotating output shaft, the motor being fixedly engaged with the object to be rotated, and a drive gear being provided at the rotating output shaft of the motor; the transmission component has a transmission component body in the shape of an annulus, the transmission component body being rotatably engaged with the object to be rotated; the transmission component is provided with a transmission gear part, the transmission gear part being used for transmission engagement with the drive gear.

[0012] Through this utility model, the power component adopts the meshing transmission of the motor drive gear and the transmission gear, which has a compact structure and high transmission efficiency. The motor is directly fixed to the object to be rotated, avoiding the complex transmission structure caused by the separation of the motor and the object to be rotated in the traditional rotating mechanism, while ensuring the synchronization of power output. The motor drive gear and the transmission gear can also adopt a separate design, so that the two do not contact each other directly, and the power is transmitted between them by a conveyor belt.

[0013] Preferably, the transmission component body has a first rotation limiting part for cooperating with the support component, and the support component has a second rotation limiting part formed at the corresponding rotational engagement part. The first rotation limiting part and the second rotation limiting part are used to cooperate to keep the relative rotation between the transmission component and the support component from deviating from the path of the engagement stroke.

[0014] Preferably, the first rotation limiting part is a groove structure or a protrusion structure that extends completely or partially in the circumferential direction, and correspondingly, the second rotation limiting part is a protrusion structure or a groove structure that extends completely or partially in the circumferential direction.

[0015] With this invention, the grooves and protrusions (or vice versa) of the first and second rotation limiting parts cooperate to restrict the relative rotation of the transmission member and the support member within a preset path, preventing mechanical interference or disengagement due to overtravel, and ensuring that the relative rotation between the transmission member and the support member is within the predetermined cooperation stroke.

[0016] Preferably, the first rotation limiting part has a boss with a circular cross-section, and the second rotation limiting part has a groove with a circular cross-section for mating with the boss. The boss is rotatably installed in the groove. The damping element is continuously or intermittently provided at the mating surface between the sides and / or the mating surface between the ends of the boss and the groove.

[0017] Preferably, the damping element is an O-shaped rubber ring, and an annular mating groove is formed along the circumferential edge of the boss body. The damping element is located in the annular mating groove and simultaneously forms a mating with the boss body and the groove body.

[0018] This invention provides stable rotation guidance through the circular cross-section of the boss and the groove. Combined with the continuous / intermittent arrangement of damping components (such as O-rings), energy is absorbed during rotation through material elastic deformation and increased friction, achieving a dynamic damping effect. This design simplifies the assembly process and reduces costs, while also enhancing the uniformity of buffering through multi-directional damping coverage on the sides / ends.

[0019] Preferably, the transmission component is provided with a limiting post, and correspondingly, the support component is provided with a strip groove extending in the circumferential direction. The limiting post is used to cooperate with the strip groove to limit the engagement stroke between the transmission component and the support component; the reset assembly includes an elastic element disposed between the limiting post and the end of the strip groove.

[0020] Through this utility model, the circumferential limiting cooperation between the limiting post and the strip groove accurately controls the relative rotation angle between the transmission component and the support component, avoiding damage; the elastic component provides an automatic reset force between the limiting post and the end of the strip groove, so that when the automatic card dealing machine is stationary, the transmission component and the support component are in the initial cooperation position; the elastic component can be a spring, and the spring can be respectively set in the gap at both ends between the limiting post and the end of the strip groove.

[0021] Preferably, the rotating mechanism also has an end plate assembly that mates with a limiting post, the end plate assembly being used for fixed engagement with the limiting post passing through the slot.

[0022] According to this utility model, the end of the limiting post is provided with a screw hole, and the end plate assembly includes an annular end plate. The end plate is provided with a through hole corresponding to the screw hole at the end of the limiting post. The screw passes through the through hole and is screwed into the screw hole to fix the end plate and the limiting post, ensuring that the transmission component and the support component will not fall off, thus improving the firmness. The end plate is also provided with an auxiliary groove that is consistent with the shape of the strip groove. The auxiliary groove is used to further improve the circumferential limiting fit between the limiting post and the strip groove.

[0023] Preferably, a buffer pad is fixedly provided at the bottom of the support member, and an interference structure is formed between the buffer pad and the end plate assembly.

[0024] In this invention, the buffer pad is cylindrical, and an annular end plate is located inside the buffer pad and horizontally positioned. The outer diameter of the annular cross-section of the end plate is smaller than the inner diameter of the cylindrical buffer pad. The interference structure includes damping blocks arranged circumferentially on the outer side of the end plate. The damping blocks are located in the gap between the inner wall of the cylindrical buffer pad and the end plate. The damping blocks and the buffer pad rub against each other to form damping, which is used to reduce the vibration during the start-up and stop phases of the automatic card dealer. The buffer pad and the support are fixed as a whole, and the transmission component and the end plate are also fixed as a whole. During the start-up and stop phases of the automatic card dealer, the two components rotate and reset relative to each other within a certain range. At this time, the damping blocks provide damping between the end plate and the inner wall of the buffer pad, further reducing the vibration during the start-up and stop phases. The buffer pad, which has a certain degree of elasticity, can also absorb the vibration energy of the rotating mechanism during operation, reduce the impact force transmitted to the support, thereby reducing noise and improving operational stability. At the same time, it increases the friction with the placement surface, further improving operational stability.

[0025] An automatic card machine includes a card machine body, which comprises a card machine main body serving as the object to be rotated and the aforementioned rotating mechanism.

[0026] This invention utilizes a rotating mechanism in an automatic card machine, enabling the card machine body, as the object to be rotated, to achieve a smooth and low-noise rotational motion. Combined with damping and reset functions, it enhances the user experience. Attached Figure Description

[0039] Support member 220, which supports transmission member 210 and has a circumferential engagement stroke with transmission member 210; and

[0040] The damping element 230 is used to achieve indirect contact between the transmission element 210 and the support element 220, and to provide resistance when the transmission element 210 and the support element 220 rotate relative to each other at the engagement stroke.

[0041] In this embodiment, the rotating mechanism achieves active and controllable rotation of the object to be rotated 110 through the rotatable engagement of the transmission component 210 and the drive component 310 fixed to the object to be rotated 110. The circumferential engagement stroke design between the support component 220 and the transmission component 210 allows the transmission component 210 to rotate relative to the support component 220 within a certain angle range. The indirect contact design of the damping component 230 provides resistance during relative rotation, effectively buffering the impact during rotation and the start-stop phase, reducing mechanical vibration and noise, and improving the stability and service life of the rotating mechanism.

The transmission component 210 and the support component 220 can achieve relative rotation within a certain range at the mating stroke. The reset component 410 enables the transmission component 210 and the support component 220 to automatically return to the initial mating position after completing the relative rotation, ensuring the accuracy and consistency of the mechanism's repetitive actions.

[0045] In this embodiment, the power assembly 310 uses the meshing transmission of the motor 510 driving gear 530 and the transmission gear 610, which is compact and has high transmission efficiency. The motor 510 is directly fixed to the object to be rotated 110, avoiding the complex transmission structure caused by the separation of the motor 510 and the object to be rotated 110 in the traditional rotating mechanism, while ensuring the synchronization of power output. The motor 510 driving gear 530 and the transmission gear 610 can also be designed separately, with the two not in direct contact, and the power is transmitted between them by the conveyor belt 320.

[0046] In this embodiment, the transmission component body 660 has a first rotation limiting part 620 for cooperating with the support member 220, and the support member 220 has a second rotation limiting part 710 formed at the corresponding rotational engagement part. The first rotation limiting part 620 and the second rotation limiting part 710 are used to cooperate to keep the relative rotation between the transmission component 210 and the support member 220 from deviating from the path of the engagement stroke.

[0047] In one specific embodiment of the present invention, the first rotation limiting part 620 is a groove structure or a protrusion structure that extends completely or partially in the circumferential direction, and correspondingly, the second rotation limiting part 710 is a protrusion structure or a groove structure that extends completely or partially in the circumferential direction.

[0048] In this embodiment, the grooves and protrusions (or vice versa) of the first rotation limiting part 620 and the second rotation limiting part 710 cooperate to restrict the relative rotation of the transmission member 210 and the support member 220 within a preset path, preventing mechanical interference or disengagement due to overtravel, and ensuring that the relative rotation between the transmission member 210 and the support member 220 is within the predetermined cooperation stroke.

[0049] In this embodiment, the first rotation limiting part 620 has a boss body 630 with a circular cross-section, and the second rotation limiting part 710 has a groove body 720 with a circular cross-section for fitting with the boss body 630. The boss body 630 is rotatably fitted into the groove body 720. The damping member 230 is continuously or intermittently disposed at the mating surface between the sides and / or the mating surface between the ends of the boss body 630 and the groove body 720.

[0050] In this embodiment, the damping member 230 is an O-shaped rubber ring, and the outer peripheral edge of the boss body 630 is formed with an annular mating groove 670 in the circumferential direction. The damping member 230 is disposed in the annular mating groove 670 and simultaneously forms a mating with the boss body 630 and the groove body 720.

[0051] In this embodiment, the circular cross-sections of the boss 630 and the groove 720 provide stable rotation guidance. Combined with the continuous / intermittent arrangement of the damping element 230 (such as an O-ring), energy is absorbed during rotation through material elastic deformation and increased friction, achieving a dynamic damping effect. This design simplifies the assembly process and reduces costs, while also enhancing the uniformity of buffering through multi-directional damping coverage on the sides / ends.

[0052] In this embodiment, a limiting post 640 is provided at the transmission member 210, and correspondingly, a strip groove 730 extending in the circumferential direction is provided at the support member 220. The limiting post 640 is used to cooperate with the strip groove 730 to limit the cooperation stroke between the transmission member 210 and the support member 220; the reset assembly 410 includes an elastic member 420 disposed between the limiting post 640 and the end of the strip groove 730.

[0053] In this embodiment, the circumferential limiting fit between the limiting post 640 and the strip groove 730 precisely controls the relative rotation angle between the transmission component 210 and the support component 220, preventing damage; the elastic component 420 provides an automatic reset force between the ends of the limiting post 640 and the strip groove 730, so that when the automatic card dealer is stationary, the transmission component 210 and the support component 220 are in the initial fit position; the elastic component 420 can be a spring, and the spring can be respectively set in the gaps at both ends between the ends of the limiting post 640 and the strip groove 730.

[0054] In this embodiment, the rotating mechanism also has an end plate assembly 240 that cooperates with the limiting post 640. The end plate assembly 240 is used to fix the limiting post 640 that passes through the strip groove 730.

[0055] In this embodiment, the end of the limiting post 640 is provided with a screw hole 650, and the end plate assembly 240 includes an annular end plate 810. The end plate 810 is provided with a through hole 820 corresponding to the screw hole 650 at the end of the limiting post 640. The screw 820 passes through the through hole 820 and is screwed into the screw hole 650 to fix the end plate 810 and the limiting post 640, ensuring that the transmission component 210 and the support component 220 will not fall off, thus improving the firmness. The end plate 810 is also provided with an auxiliary groove 830 that is consistent with the shape of the strip groove 730. The auxiliary groove 830 is used to further improve the circumferential limiting fit effect between the limiting post 640 and the strip groove 730.

[0056] In this embodiment, a buffer pad 250 is fixedly provided at the bottom of the support member 220, and an interference structure 260 is formed between the buffer pad 250 and the end plate assembly 240.

The interference structure 260 includes a damping block 811 arranged circumferentially on the outer side of the end plate 810. The damping block 811 is located in the gap between the inner wall of the cylindrical buffer pad 250 and the end plate 810.

The buffer pad 250 is fixed to the support member 220. As a whole, the transmission component 210 and the end plate 810 are also fixed as a whole. During the start-up and stop phases of the automatic card dealing machine, the two components undergo relative rotation and reset actions within a certain range. At this time, the damping block 811 provides damping between the end plate 810 and the inner wall of the buffer pad 250, further reducing the vibration during the start-up and stop phases. The buffer pad 250, which has a certain elasticity, can also absorb the vibration energy during the operation of the rotating mechanism, reduce the impact force transmitted to the support component 220, thereby reducing noise and improving the smoothness of operation. At the same time, it increases the friction with the placement surface, further improving the smoothness of operation.
