[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] like Figures 1 to 11 The shown is a limiting structure applied to a conveying device, including a housing 1. The housing 1 is provided with a transfer mechanism 2. The transfer mechanism 2 is provided with a rotating member 3. The rotating member 3 is provided with a receiving cavity 31 for accommodating an object and a first opening 32 for the object to enter the receiving cavity 31. The housing 1 is also provided with a driving device 4 for driving the rotating member 3 to rotate in the forward and reverse directions, and a limiting mechanism 5 movably configured to limit the rotation direction of the driving device 4. The driving device 4 or the rotating member 3 is provided with a plurality of abutting parts 41. The abutting parts 41 are provided with a guide end 411 that cooperates with one side of the limiting mechanism 5 and a locking end 412 that abuts with the other side of the limiting mechanism 5.

[0031] When the rotating member 3 rotates in the forward direction and the object is engaged in the first opening 32 of the rotating member, the driving device 4 drives the rotating member 3 to rotate in the reverse direction so that the abutting part 41 abuts and engages with the engaging end 412. The driving device 4 drives the rotating member 3 to rotate in the forward direction to form a cycle until the object is disengaged from the first opening 32 of the rotating member or enters the receiving cavity 31.

[0032] This invention uses a drive device that switches between forward and reverse rotation. When ice blocks accumulate and become stuck at the entrance of the receiving cavity, preventing the transfer mechanism from rotating, the drive device is driven to rotate in the reverse direction. By utilizing the cooperation between the abutment part and the limiting mechanism, the drive device is driven to rotate forward again. Through multiple cycles, the ice blocks can be automatically released from the stuck state without frequent manual intervention, greatly reducing labor and time costs and effectively improving ice-making efficiency.

[0033] Traditional ice-making devices often require manual intervention or forced rotation when ice blocks get stuck, which can overload or even damage the drive unit. This new invention, however, avoids prolonged excessive stress on the drive unit through automatic reverse rotation and cyclical attempts, effectively protecting the drive unit and extending the machine's lifespan. The automatic anti-jamming and cyclical attempt mechanism responds quickly to ice block jamming, repeatedly attempting to feed the ice block into the receiving cavity or dislodge it from the jammed position, thereby reducing ice-making interruptions caused by ice block jamming and improving overall ice-making efficiency.

[0034] In some embodiments, to reduce the repeated collisions between the ice block and both sides of the rotating component during the cycle of forward and reverse rotation, this invention drives the drive device to switch to forward rotation by engaging the abutment portion with the engaging end. This replaces the collision and engagement between the ice block and the rotating component, thereby reducing damage caused by collisions between the rotating component and the ice block. By avoiding prolonged jamming of the transfer mechanism due to ice block engagement, which would cause the drive device to be continuously overloaded, the risk of drive device damage is significantly reduced, the service life of the drive device is extended, and the reliability and durability of the entire ice-making device are improved.

[0035] Optionally, in some embodiments, a controller connected to the drive device is included. When the current of the drive device rotating in the forward direction is greater than a threshold, the controller drives the drive device to rotate in the reverse direction. When the current of the drive device rotating in the reverse direction is greater than a threshold, the controller drives the drive device to rotate in the forward direction. The controller repeatedly gives instructions to form a cycle of actions to prevent the ice block from jamming the drive device.

[0036] Optionally, in some embodiments, when the thickness of the abutting part is thin, or the distance between the guide end and the engaging end is small, the swing angle of the abutting part and the limiting mechanism is small when they cyclically abut against each other. When the angles of the forward and reverse rotation of the driving device are small, the continuous cyclic rotation of the driving device in the forward and reverse directions creates a vibration or shaking effect, which can quickly make the ice block detach from the first opening of the rotating part or enter the receiving cavity.

[0037] like Figures 1 to 11 The diagram shows a limiting structure applied to a conveying device. The driving device 4 includes a connecting shaft 6 connected to the rotating member 3 and a driving part 7 connected to the connecting shaft 6. The abutting part 41 is provided with a plurality of evenly arranged parts. The limiting mechanism 5 includes a limiting member 51 that contacts the abutting part 41 and an elastic body 52 connected to the limiting member 51. The elastic body 52 is used to drive the limiting member 51 to reset towards the abutting part 41.

[0038] Furthermore, as a preferred embodiment of this utility model and not a limitation, when the driving unit drives the rotating member to move forward via the connecting shaft, the guide end will squeeze the limiting member, causing the limiting member to move away from the abutting part. When the limiting member disengages from the guide end, the elastic body drives the limiting member to automatically reset. The abutting part continues to rotate with the driving unit or rotates with the rotating member and contacts the limiting member again through its guide end. When the ice block is stuck in the first opening of the rotating member, the driving device drives the rotating member to move in the reverse direction. The limiting member pushed by the elastic body abuts against the locking end. At this time, the rotating member cannot move in the reverse direction. The driving device drives the rotating member to move forward again. The ice block is still stuck in the first opening of the rotating member. The rotating member cannot move forward. The driving device drives the rotating member to move in the reverse direction again to form a cycle. The automatic reset mechanism of this utility model ensures the continuity and stability of the limiting mechanism during the forward and reverse rotation of the driving device.

[0039] Specifically, the contact engagement between the limiting member and the abutment portion, through the restoring action of the elastic body, can precisely limit the rotation direction of the drive device. Through the buffering and restoring force of the elastic body, the limiting member can interact with the abutment portion at appropriate times and at different positions, accurately controlling the forward and reverse switching of the drive device and ensuring the effective execution of the entire cycle.

[0040] Specifically, the elastomer can act as a buffer. When the abnormal force caused by the ice block jamming is transmitted to the drive device and the limiting mechanism, the elastomer can absorb part of the impact force, avoiding direct damage to the limiting parts, abutment parts and connecting shafts caused by rigid collisions. This further protects the internal structure of the equipment, extends the service life of the various parts of the equipment, and reduces maintenance and replacement costs.

[0041] like Figures 3 to 11 The diagram shows a limiting structure applied to a conveying device. The limiting member 51 is provided with a first contact surface 511, and the guide end 411 is provided with a guide surface 4111 that cooperates with the first contact surface 511.

[0042] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the cooperation between the guide surface and the first contact surface ensures that when the driving device drives the rotating component to rotate, the limiting component can avoid the contact portion along the guide surface. The guide surface reduces the jamming and friction of the limiting component during movement, and the setting of the limiting component will not affect the smoothness of the rotation of the rotating component during normal forward movement of the driving device.

[0043] like Figures 3 to 11 The diagram shows a limiting structure applied to a conveying device. The limiting member 51 has a first limiting surface 512 on the side away from the first contact surface 511, and the engaging end 412 has a second contact surface 4121 that contacts the first limiting surface 512.

[0044] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the contact between the first limiting surface and the second contact surface ensures that when the driving device drives the rotating member to rotate in the opposite direction, the engaging end of the abutment portion can accurately contact the first limiting surface of the limiting member and generate an engaging effect.

[0045] Optionally, in some embodiments, the contact between the first limiting surface and the second contact surface can effectively prevent the rotating part from rotating excessively. Since there are multiple abutment parts, when the locking block engages with the first opening of the rotating part multiple times, there is a certain probability that different abutment parts and locking ends will cooperate. The first limiting surface and the second contact surface can reasonably disperse and transmit the force, avoiding the overload force from being concentrated on a certain vulnerable component and causing it to be damaged. This reduces the damage caused by the rotating part repeatedly colliding with the ice block, and ensures the durability, safety and stability of the equipment.

[0046] Optionally, in some embodiments, the limiting component is made of a metal material, such as stainless steel, copper alloy, aluminum alloy, or cast iron. The limiting component can maintain a stable shape and position when subjected to large forces or torques, thereby avoiding failure due to structural deformation. During the forward and reverse rotation cycle, the angle and position of each rotation of the rotating component can be effectively controlled. Preferably, the limiting component is made of stainless steel.

[0047] like Figures 3 to 11 The diagram shows a limiting structure applied to a conveying device, wherein the guide surface 4111 and the second contact surface 4121 are arranged in a V-shape.

[0048] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the cooperation between the V-shaped connecting guide surface and the second contact surface provides precise guidance, ensuring that the rotating component can move accurately along a predetermined path during rotation. This helps reduce jamming or damage caused by directional deviation, improving the stability and reliability of the entire conveying device.

[0049] Specifically, the V-shaped guide surface and the second contact surface experience more concentrated force, allowing for rapid forward and reverse rotation via the rotation of the abutment portion. This eliminates the need for the abutment portion to move an additional distance, thus reducing the frequency of forward and reverse rotation. The V-shaped structure also facilitates force transmission and distribution. When the drive device applies torque to rotate the component, the force between the abutment portion and the limiting component is distributed along the two surfaces of the V-shape, optimizing force distribution. This reduces wear and deformation caused by uneven force distribution, extending the service life of the limiting mechanism and the rotating component.

[0050] Optionally, in some embodiments, the moving distance of the abutment portion is reduced. When the angles of the forward and reverse rotation of the drive device are small, the continuous forward and reverse rotation of the drive device creates a vibration or shaking effect, which can quickly cause the ice block to detach from the first opening of the rotating part or enter the receiving cavity.

[0051] like Figures 2 to 7 The diagram shows a limiting structure applied to a conveying device, wherein the guide surface 4111 is arc-shaped, the first contact surface 511 is inclined, the second contact surface 4121 is straight, the first contact surface 511 is inclined from away from the abutment portion 41 towards the abutment portion 41 and from top to bottom, and the first limiting surface 512 is straight and parallel to the extension direction of the limiting member 51.

[0052] Furthermore, as a preferred embodiment of this utility model and not a limitation, the guide surface being arc-shaped can provide a smooth transition and guidance, reducing resistance and friction of the rotating component during movement. Arc-shaped guidance helps ensure that the rotating component can move smoothly along a predetermined path during rotation, avoiding jamming or jumping.

[0053] Of course, the guide surface can also be an inclined plane.

[0054] In addition, the first contact surface is designed as an inclined plane, and it is inclined from the direction away from the abutment to the direction closer to the abutment and from top to bottom. In this way, during the contact between the abutment and the limiting member, the transmitted force will be decomposed along the inclined plane, which helps to reduce the impact and vibration caused by sudden locking.

[0055] Specifically, the straight-shaped second contact surface, in conjunction with the straight-shaped first limiting surface, provides a stable contact surface, ensuring stability and reliability after engagement. Straight-face contact helps reduce wear and deformation caused by insufficient contact area.

[0056] Specifically, the first limiting surface is straight and parallel to the extension direction of the limiting member. This arrangement provides stable support and limiting function, enhancing structural strength and stability. The straight limiting surface helps prevent deformation or damage caused by uneven stress.

[0057] like Figures 1 to 8 The diagram illustrates a limiting structure applied to a conveying device. The limiting mechanism 5 includes a limiting housing 53 connected to a housing 1. The limiting housing 53 has a limiting housing receiving cavity 531 that accommodates the limiting member 51 and the elastic body 52. ​​The elastic body 52 abuts against the inner walls of the limiting member 51 and the limiting housing receiving cavity 531, respectively. The housing 1 has a housing extension end 11 extending outward. One end of the driving part 7 is connected to the housing extension end 11. The limiting housing 53 is located between the driving part 7 and the housing 1.

[0058] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, by using a limiting housing connected to the housing to accommodate the limiting member and the elastic body, it is possible to reduce the erosion and jamming caused by external dust, foreign objects, and moisture contacting the limiting member and the elastic body. This ensures that the limiting member and the elastic body can always maintain the correct relative position under various vibrations and shaking conditions during the operation of the conveying device. This arrangement makes the entire limiting mechanism compact and occupies little space. The housing has a housing extension end extending outward, with one end of the drive unit connected to the housing extension end, and the limiting housing located between the drive unit and the housing. This layout makes full use of the internal space of the conveying device, making the arrangement of each component more compact and reasonable, further improving the integration of the entire device, and making the conveying device simpler and more aesthetically pleasing.

[0059] Specifically, the elastomer abuts against the inner walls of the limiting member and the limiting housing cavity, providing a stable limiting effect. The elastomer also acts as a buffer, reducing impact and vibration caused by the movement of the limiting member and protecting other components from damage. The connection design between the limiting housings simplifies the installation process, allowing the limiting mechanism to be installed without complicated procedures. It also facilitates subsequent maintenance and replacement, reducing maintenance costs and time.

[0060] like Figures 2 to 8 The diagram shows a limiting structure applied to a conveying device, wherein the abutment portion 41 is axially disposed on the outer side of the connecting shaft 6, the abutment portion 41 is toothed, and the moving direction of the limiting member 51 is perpendicular to the extending direction of the connecting shaft 6.

[0061] Furthermore, as a preferred embodiment of this utility model and not a limitation, the abutment portion is arranged axially along the outer side of the connecting shaft. This allows the torque to be effectively transmitted to the abutment portion along the axial direction of the connecting shaft when the drive device is running, thereby acting on the limiting mechanism to achieve precise control of the rotation direction of the rotating component. The force transmission path is more direct and efficient, reducing force loss and dispersion during transmission. This layout makes the entire mechanism more compact and occupies less space. The tooth-shaped abutment portion provides a locking function at its engaging end, and also enhances the strength and stability of the structure. When subjected to external force, the teeth can disperse stress, reducing deformation or damage caused by stress concentration.

[0062] Specifically, the moving direction of the limiting member is perpendicular to the extending direction of the connecting shaft. When the abutment rotates with the connecting shaft and interacts with the limiting member, the perpendicular relationship directly converts the circumferential force generated by the rotation into a linear force of the limiting member along its moving direction. This allows the limiting member to accurately control the position and rotation direction of the abutment through its own movement and cooperation with the elastic body, achieving precise control of the forward and reverse rotation of the drive device. Preferably, the limiting member can be located on the side of the connecting shaft. The installation and maintenance process of the abutment and the limiting member is simpler. Workers can easily install, disassemble, and replace components, reducing maintenance costs and time.

[0063] Optionally, in some embodiments, when the engaging end abuts against the limiting member, the limiting member can gradually generate resistance along the inclined surface of the teeth during movement until a stable engaging state is reached, reducing the impact and vibration caused by sudden engagement.

[0064] like Figures 9 to 11 The diagram shows a limiting structure applied to a conveying device. The abutting part 41 is disposed inside the rotating member 3. When the rotating member 3 rotates, the abutting part 41 drives the limiting member 51 to move away from the rotating member 3 through the guide end 411. When the limiting member 51 is reset, it moves towards the rotating member 3.

[0065] Optionally, in some embodiments, the abutment portion extends along the axial direction of the rotating member and is disposed on its inner side, making full use of the space inside the rotating member and making the whole structure more compact. When the rotating member rotates, the force is transmitted along the axis of the rotating member to the abutment portion on the inner side, and the limiting member can move smoothly along the path of the guide end.

[0066] Optionally, in some embodiments, the abutment portion may move along a straight line or rotate about an axis.

[0067] Specifically, when the abutting part moves in a straight line, the first contact surface 511 is an inclined surface, the guide surface 4111 is straight, and the second contact surface 4121 is straight. The first contact surface 511 extends into the inner side of the rotating member 3 at an incline from away from the abutting part 41 towards the abutting part 41. The first limiting surface 512 is straight and parallel to the extending direction of the limiting member 51. The first contact surface 511 faces the guide surface 4111, and the first limiting surface 512 faces the second contact surface 4121. The elastic body 52 pushes the abutting part to move towards the rotating member. When the guide surface contacts the first contact surface, the abutting part avoids and moves away from the rotating member. When the rotating member rotates in the opposite direction, the two straight second contact surfaces and the first limiting surface abut against each other, causing the abutting part and the limiting member to engage.

[0068] like Figures 9 to 11The diagram illustrates a limiting structure applied to a conveying device. The limiting member 51 has a fixed shaft 54, and the elastic body 52 is connected to the fixed shaft 54. The limiting member 51 rotates around the fixed shaft 54, and the fixed shaft 54 ​​is vertically connected to the housing 1. The guide surface 4111 is straight, the first contact surface 511 is straight, and the second contact surface 4121 is straight. The first contact surface 511 extends obliquely into the inner side of the rotating member 3 from away from the abutment portion 41 towards the abutment portion 41, with the first contact surface 511 facing the guide surface 4111. The first limiting surface 512 is arc-shaped and convex towards the second contact surface 4121, forming a V-shape between the first contact surface 511 and the first limiting surface 512.

[0069] Furthermore, as a preferred embodiment of this utility model and not a limitation, the limiting member is reset by rotation around a fixed axis via an elastic body, and can automatically return to its initial position when no external force is applied. Simultaneously, when the rotating member rotates and pushes the abutment portion, the limiting member can be compressed or rotated to accommodate the movement of the rotating member. Once the external force disappears, the limiting member will reset under the action of the elastic body and re-establish contact with the abutment portion. Therefore, when the rotating member moves normally in the forward direction, the limiting member will not affect the smoothness of the rotating member.

[0070] Specifically, the vertically positioned fixed shaft allows the limiting component to rotate in the horizontal plane, improving the accuracy of the swing angle when the limiting component contacts the abutment part. The vertically positioned fixed shaft and the limiting component connected by an elastic body make the entire mechanism easier to install and maintain. Workers can easily install, disassemble, and replace components, reducing maintenance costs and time.

[0071] Optionally, in some embodiments, the abutment portion has a straight structure, and the guide surface and the second contact surface are located on both sides of the abutment portion and close to the connecting shaft. The straight first contact surface can be inclined or planar. When the rotating member rotates in the forward direction, the guide surface moves towards the first contact surface and contacts the first contact surface. The limiting member avoids the guide surface and rotates away from the rotating member. When the guide surface disengages from the first contact surface, the limiting member will reset under the action of the elastic body, and the guide surface will contact the first contact surface again.

[0072] Optionally, in some embodiments, when the rotating member rotates in the reverse direction, and the second contact surface moves toward the limiting member, the first limiting surface is arc-shaped and protrudes toward the second contact surface, and the second contact surface is straight. When the second contact surface contacts the first limiting surface, it will push the limiting member to continue moving toward the receiving cavity. Since the elastic body is already connected to the fixed shaft, this will cause the limiting member to be unable to continue moving, thereby causing the second contact surface to abut against the first limiting surface. The driving device drives the rotating member to rotate in the forward direction, and the guide surface moves toward the first contact surface and contacts the first contact surface.

[0073] The first contact surface 511 extends into the inner side of the rotating member 3 at an angle from away from the abutment part 41 toward the abutment part 41. This arrangement can push the ice towards the receiving cavity. The limiting member is located near the highest point of the rotating member, which can prevent the ice block from falling out of the receiving cavity at a high point.

[0074] Optionally, in some embodiments, the limiting member is provided with a limiting member positioning part 513 that abuts against the housing. The housing is provided with a housing opening into which part or all of the limiting member extends. When the second contact surface contacts the first limiting surface, and the limiting member is pushed to continue moving towards the receiving cavity, the limiting member positioning part located outside the housing opening will abut against the housing. The limiting member positioning part is engaged on the outer wall of the housing opening, thereby restricting the limiting member from continuing to move.

[0075] Specifically, the V-shaped first contact surface and the first limiting surface experience more concentrated force, allowing for rapid forward and reverse rotation via the rotation of the abutment portion. This eliminates the need for the abutment portion to move an additional distance, thus reducing the frequency of forward and reverse rotation. The V-shaped structure also facilitates force transmission and decomposition. When the drive device applies torque to rotate the component, the force between the abutment portion and the limiting component is decomposed along the two surfaces of the V-shape, optimizing force distribution. This reduces wear and deformation caused by uneven force distribution, extending the service life of the limiting mechanism and the rotating component.

[0076] Optionally, in some embodiments, the moving distance of the abutment portion is reduced. When the angles of the forward and reverse rotation of the drive device are small, the continuous forward and reverse rotation of the drive device creates a vibration or shaking effect, which can quickly cause the ice block to detach from the first opening of the rotating part or enter the receiving cavity.

[0077] like Figures 1 to 7 As shown, the ice-making apparatus includes the limiting structure applied to the conveying device as described above.

[0078] Furthermore, as a preferred embodiment of this utility model and not a limitation, when the ice block gets stuck in the first opening of the rotating component, the limiting structure can react quickly and resolve the sticking by rapidly performing forward and reverse rotation operations through the drive device, allowing the ice-making device to return to normal operation as soon as possible. Compared to traditional ice-making devices, it shortens the downtime due to malfunctions, ensuring efficient ice-making operations, and better meets the usage requirements, especially in scenarios such as commercial venues where there is a high demand for ice and a continuous supply requirement.

[0079] Furthermore, in the past, when ice blocks jammed and caused the rotating mechanism to seize up, manual intervention was often required, consuming a significant amount of time and manpower, and forcing the ice-making process to be interrupted. With this limiting structure, its ability to automatically handle ice block jamming avoids frequent manual intervention. The ice-making device can continuously make and deliver ice blocks without interruption, effectively saving time spent on manual troubleshooting, increasing the amount of ice produced per unit time, and improving the overall ice-making efficiency of the device.

[0080] Optionally, in some embodiments, when the ice block is engaged, if the angles of the forward and reverse rotation of the driving device are small, the driving device continuously rotates in the forward and reverse directions to create a vibration or shaking effect, which can quickly cause the ice block to disengage from the first opening of the rotating component or enter the receiving cavity.

[0081] Example 1

[0082] like Figures 1 to 11 The shown is a limiting structure applied to a conveying device, including a housing 1. The housing 1 is provided with a transfer mechanism 2. The transfer mechanism 2 is provided with a rotating member 3. The rotating member 3 is provided with a receiving cavity 31 for accommodating an object and a first opening 32 for the object to enter the receiving cavity 31. The housing 1 is also provided with a driving device 4 for driving the rotating member 3 to rotate in the forward and reverse directions, and a limiting mechanism 5 movably configured to limit the rotation direction of the driving device 4. The driving device 4 or the rotating member 3 is provided with a plurality of abutting parts 41. The abutting parts 41 are provided with a guide end 411 that cooperates with one side of the limiting mechanism 5 and a locking end 412 that abuts with the other side of the limiting mechanism 5.

[0083] When the rotating member 3 rotates in the forward direction and the object is engaged in the first opening 32 of the rotating member, the driving device 4 drives the rotating member 3 to rotate in the reverse direction so that the abutting part 41 abuts and engages with the engaging end 412. The driving device 4 drives the rotating member 3 to rotate in the forward direction to form a cycle until the object is disengaged from the first opening 32 of the rotating member or enters the receiving cavity 31.

[0084] This invention, through the forward and reverse switching of the drive device 4, can automatically attempt to disengage the ice block when it accumulates and gets stuck at the entrance of the accommodating cavity 31, preventing the transfer mechanism 2 from rotating. This is achieved by utilizing the cooperation between the abutment part 41 and the limiting mechanism 5. This eliminates the need for frequent manual intervention, greatly reducing labor and time costs and effectively improving ice-making efficiency.

[0085] Traditional ice-making devices often require manual intervention or forced rotation when ice blocks get stuck, which can overload or even damage the drive unit 4. This invention, however, avoids prolonged excessive force on the drive unit 4 through automatic reverse rotation and cyclical attempts, effectively protecting it and extending the machine's lifespan. The automatic anti-jamming and cyclical attempt mechanism responds quickly to ice block jamming, repeatedly attempting to feed the ice block into the receiving cavity 31 or dislodge it from the jammed position, thereby reducing ice-making interruptions caused by ice block jamming and improving overall ice-making efficiency.

[0086] The driving device 4 includes a connecting shaft 6 connected to the rotating member 3 and a driving part 7 connected to the connecting shaft 6. The abutting part 41 is provided in multiple and evenly arranged. The limiting mechanism 5 includes a limiting member 51 that contacts the abutting part 41 and an elastic body 52 connected to the limiting member 51. The elastic body 52 is used to drive the limiting member 51 to reset towards the abutting part 41.

[0087] When the drive unit 7 drives the rotating member 3 to move forward via the connecting shaft 6, the guide end 411 will squeeze the limiting member 51, causing the limiting member 51 to move away from the abutting part 41. When the limiting member 51 disengages from the guide end 411, the elastic body 52 drives the limiting member 51 to automatically reset. The abutting part 41 continues to rotate with the drive unit 7 or with the rotating member 3 and contacts the limiting member 51 again through the guide end 411. When the ice block is stuck in the first opening 32 of the rotating member, the drive device 4 drives the rotating member 3 to move in the opposite direction. The elastic body 52 pushes the limiting member 51 to abut against the locking end 412. At this time, the rotating member 3 cannot move in the opposite direction. The drive device 4 drives the rotating member 3 to move forward again. The ice block is still stuck in the first opening 32 of the rotating member. The rotating member 3 cannot move forward. The drive device 4 drives the rotating member to move in the opposite direction again to form a cycle. The automatic reset mechanism of this utility model ensures the continuity and stability of the limiting mechanism during the forward and reverse rotation of the drive device 4.

[0088] Example 2

[0089] Based on Example 1, Example 2 further includes the following implementation method: it also includes a controller connected to the drive device 4. When the current of the drive device 4 rotating in the forward direction is greater than a threshold, the controller drives the drive device 4 to rotate in the reverse direction. When the current of the drive device 4 rotating in the reverse direction is greater than a threshold, the controller drives the drive device 4 to rotate in the forward direction to form a cycle.

[0090] When ice blocks get stuck, if the angles of the forward and reverse rotation of the drive device 4 are small, the drive device 4 will continuously rotate in the forward and reverse directions to create a vibration or shaking effect, which can quickly make the ice blocks detach from the first opening 32 of the rotating part or enter the receiving cavity 31.

The first contact surface 511 is inclined from the direction away from the abutment part 41 towards the abutment part 41 and from top to bottom. The first limiting surface 512 is straight and parallel to the extension direction of the limiting member 51.

[0098] The limiting mechanism 5 includes a limiting housing 53 connected to the housing 1. The limiting housing 53 has a limiting housing receiving cavity 531 for accommodating the limiting member 51 and the elastic body 52. ​​The elastic body 52 abuts against the inner walls of the limiting member 51 and the limiting housing receiving cavity 531 respectively. The housing 1 has a housing extension end 11 extending outward. One end of the driving part 7 is connected to the housing extension end 11. The limiting housing 53 is located between the driving part 7 and the housing 1.

[0099] Example 6

[0100] Based on Embodiment 3, Embodiment 6 also has the following implementation method: The abutting part 41 is disposed on the inner side of the rotating member 3. When the rotating member 3 rotates, the abutting part 41 drives the limiting member 51 to move away from the rotating member 3 through the guide end 411. When the limiting member 51 is reset, it moves towards the rotating member 3.

[0101] The abutment portion moves along a straight line. The first contact surface 511 is an inclined surface, the guide surface 4111 is a straight surface, and the second contact surface 4121 is a straight surface. The first contact surface 511 is inclined and extends into the inner side of the rotating member 3 from away from the abutment portion 41 towards the abutment portion 41.

The first contact surface 511 faces the guide surface 4111, and the first limiting surface 512 faces the second contact surface 4121.

[0108] When ice blocks become stuck, the limiting structure reacts quickly, using the drive device 4 to rapidly reverse the direction of rotation to resolve the issue, allowing the ice-making device to return to normal operation as soon as possible. Compared to traditional ice-making devices, it reduces downtime due to malfunctions, ensuring efficient ice-making operations. This is particularly beneficial in scenarios such as commercial establishments where there is a high demand for ice and a need for continuous supply, better meeting the requirements of these environments.

[0109] Furthermore, in the past, when ice blocks jammed and caused the rotating mechanism to seize up, manual intervention was often required, consuming a significant amount of time and manpower, and forcing the ice-making process to be interrupted.
