Technical Field

[0001] This utility model relates to the field of cold drink equipment, specifically an ice cream machine. Background Technology

[0002] Throughout the development of ice cream machines, the stability of their internal drive system, the lifespan of the motor, and the ease of component installation and maintenance have always been key factors affecting equipment performance and user experience. As market demands for efficient, stable, and easy-to-operate ice cream machines continue to rise, the shortcomings of traditional ice cream machines in these areas are becoming increasingly apparent.

[0003] In traditional ice cream machines, the movements of the drive motor and the axial motor are often interconnected, and their power transmission paths can interfere with each other. This design necessitates a complex structure to coordinate the movements of both motors during installation, increasing the difficulty of installation layout and making the components prone to resonance due to vibration transmission. After long-term operation, the installation structure of the drive components is prone to loosening, thereby increasing the probability of equipment failure and affecting the continuous and stable operation of the ice cream machine.

[0004] Furthermore, traditional ice cream machines mostly use mechanical connections such as bolts and clips for the blades and drive shafts. These connections require precise alignment during installation, are cumbersome, and often require specialized tools, causing considerable inconvenience to users. Cleaning the blades is similarly complicated, time-consuming, and laborious, and improper handling can damage components. Summary of the Invention

[0010] Preferably, the axial drive assembly includes an axial motor and an axial screw, the drive shaft positioning plate is threadedly connected to the axial screw, and the drive shaft is rotatably mounted at the central position of the drive shaft positioning plate.

[0011] Preferably, the transmission gear set includes a driven gear through which the drive shaft passes, and the drive shaft is keyed to the driven gear.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention improves the installation stability of the drive components, reduces vibration and resonance, lowers the probability of failure, reduces the load on the axial motor, extends its lifespan, and ensures stable operation by completely separating the drive motor and axial motor movements.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-3 This utility model provides a technical solution: an ice cream machine, including: a shell 1, a cup and a lid 13. The lid 13 is adapted to the blade 11. A first magnet 6 is fixedly installed on the top of the lid 13. A pad is magnetically connected to the top of the first magnet 6. The shape of the pad matches the shape of the top of the first magnet 6, ensuring that the two can be tightly attracted and not easily fall off. The edge of the lid 13 is provided with a groove or buckle structure that matches the outer periphery of the cup, so that the lid 13 can be accurately and firmly covered on the cup.

[0017] The drive assembly, housed within the housing 1, includes a drive motor 2, a transmission gear set 12, an axial drive component, a drive shaft positioning plate 9, and a drive shaft 5 extending from the housing 1. The drive motor 2 is connected to the drive shaft 5 via the transmission gear set 12 to drive the drive shaft 5 to rotate around its axis. The axial drive component drives the drive shaft positioning plate to move the drive shaft 5 back and forth along its axis. These two motion modes can be independently or collaboratively controlled by the control system, enabling the drive shaft 5 to perform complex operations such as rotary cutting while simultaneously performing axial feed. This separation allows both components to be installed in the most suitable fixed position and method according to their respective functional requirements, without needing to consider complex installation layout adjustments due to motion interference. The axial drive assembly includes an axial motor 3 and an axial screw 4. A drive shaft positioning plate 9 is threadedly connected to the axial screw 4. The drive shaft 5 is rotatably mounted at the center of the drive shaft positioning plate 9. The transmission gear set 12 consists of multiple meshing gears, including a driving gear, intermediate transition gears, and a driven gear 10 connected to the drive shaft 5. The number of teeth and module of each gear are precisely set according to the power transmission requirements. The drive shaft 5 is keyed to the driven gear 10, or the drive shaft 5 can be configured as a rectangular structure. A rectangular hole adapted to the driven gear 10 is provided at the center of the driven gear 10. The rotational power of the drive shaft 5 is independently provided by the drive motor 2 through the transmission gear set 12. The axial motor 3 only needs to bear the force required for the axial movement of the drive shaft 5 and does not need to bear the rotational load.

[0018] A detachable component, located at the end of the drive shaft 5, includes a drive shaft connector 7 and a cutter head 11. The cutter head 11 is detachably mounted to the end of the drive shaft 5 via the drive shaft connector 7. The bottom end of the drive shaft 5 is provided with a threaded hole for accommodating the drive shaft connector 7. The drive shaft connector 7 is threaded into the threaded hole. The top of the cutter head 11 is provided with a connecting part adapted to the drive shaft connector 7. The connecting part is axially keyed to the drive shaft connector 7. A second magnet 8 is fixedly mounted on the bottom of the drive shaft connector 7. The connecting part of the cutter head 11 is magnetically connected to the second magnet 8. The magnetic pole direction of the second magnet 8 is adapted to the magnetic attraction requirements of the connecting part. Its bottom surface is flush with or slightly protrudes from the bottom surface of the drive shaft connector 7. The drive shaft connector 7 serves as an intermediate transition, preventing direct connection between the cutter head 11 and the drive shaft 5. When the cutter head 11 is impacted during operation, the drive shaft connector 7 can buffer the impact force to a certain extent, reducing the direct impact on the drive shaft 5, protecting the drive shaft 5 from damage, and extending the service life of the drive shaft 5.

[0019] The cutter head 11 is magnetically connected to the second magnet 8 at the bottom of the drive shaft connector 7 via a connecting part. When the connecting part of the cutter head 11 is brought close to the drive shaft connector 7, the connecting part is automatically attracted and guided to the correct installation position under the action of magnetic force, achieving rapid positioning of the cutter head 11. This magnetic positioning method eliminates the need for precise manual alignment, and even in poor visibility or confined operating space, the initial installation of the cutter head 11 can be easily completed, greatly reducing installation difficulty and improving installation efficiency.

[0020] The cutter head 11 and the drive shaft 5 are combined through a magnetic connection and an axial key connection, forming a double-fixed structure. The axial key connection mainly serves to transmit circumferential power and prevent relative rotation, while the magnetic connection provides a continuous axial attraction force. This attraction force can effectively counteract the axial vibration and slight displacement tendency generated by the cutter head 11 during high-speed rotation or operation, ensuring that the connection part and the drive shaft connector 7 always maintain a tight fit, further enhancing the overall stability of the connection and reducing safety hazards caused by loose connections.

[0021] This application improves the installation stability of the drive components, reduces vibration and resonance, lowers the probability of failure, reduces the load on the axial motor, extends its life and ensures stable operation by completely separating the operation of the drive motor 2 and the axial motor 3. The cutter head 11 and the cup cover are magnetically attached, which simplifies the installation and disassembly process. Quick assembly and separation can be achieved without complicated operations, which improves the ease of use. At the same time, it is easy to operate when cleaning or replacement is required, which reduces the difficulty of maintenance and further enhances the practicality of the device.
