Description

Technical Field

[0001] This invention relates to an ice cream equipment, and more particularly to an integrated ice cream preparation and extrusion machine and its working method. Background Technology

[0002] As people's living standards continue to improve, the demand for ice cream, as a popular cold drink, is also increasing.

[0003] Traditional ice cream making machines mainly consist of two parts: a mixer and an extruder. The mixer is responsible for thoroughly mixing and stirring the ice cream base. During the high-speed rotation of the blades, air is injected into the ice cream liquid, causing it to expand in volume and increasing its fluffiness, ensuring a smooth texture and uniform consistency in the finished product. The extruder, on the other hand, extrudes the ice cream into the desired shape after mixing. However, this separate equipment design presents several inconveniences in actual production: the equipment is large and occupies a lot of space; the operation process is relatively cumbersome, requiring frequent manual movement, which increases labor costs; and transferring ice cream liquid between machines can easily cause contamination or leakage, affecting food safety.

[0004] Given the shortcomings of existing technologies, it is particularly important to develop a composite ice cream making machine that integrates mixing and extrusion functions. This would not only save equipment space and reduce investment costs, but also simplify the production process, improve overall operational efficiency and product quality, which would greatly promote technological progress and development in the ice cream making industry.

[0023] Furthermore, the container placement seat 29 is provided with an elastic auxiliary component that causes the container 3 to rotate in the unlocking direction.

[0032] Furthermore, it also includes multiple limit switches for detecting the position of the moving assembly.

[0033] Furthermore, the container includes a cylindrical body 31 with open ends, an upper cover installed on the upper end of the cylindrical body 31, and a lower cover 32 installed on the lower end of the cylindrical body 31.

The second slot 321 can be axially inserted into the first slot 411 at the bottom of the piston assembly and is used for radial engagement with the second engagement part 519 on the clutch mechanism.

[0034] Meanwhile, the present invention also provides a method for operating an integrated ice cream extrusion machine, which includes the following steps: S1. Loading: Insert the container 3 containing the material into the placement hole 290 of the container placement seat 29 at the first position, and rotate it to the second position to fix it. At this time, the bottom of the piston assembly is fixed to the bottom of the container 3, the cutter 43 is disengaged from the piston assembly, and the push rod 25 is disengaged from the piston assembly; S2, Preparation, the moving assembly moves, driving the push rod 25 and the main shaft 24 to move synchronously; During the upward movement, push rod 25 can disengage the cutter 43 from the piston assembly; At the same time, the spindle 24 rotates. During the process of the spindle 24 rising and rotating, it is connected to the tool 43 through the helical teeth at its end and drives the tool 43 to rotate. The helical teeth provide the tool 43 with a radial force for circumferential rotation and a pulling force to move closer to the spindle. S3. By rotating and moving the cutter 43 up and down inside the container 3, the material inside the container 3 is crushed and stirred. S4. Reset I: After one or more mixing and crushing operations, the moving assembly resets in the direction away from the container, and the main shaft 24 stops rotating. As the moving assembly resets, the push rod disengages from the latch, thus fixing the tool on the piston assembly; S5. After preparation is complete, container 3 can be rotated from the second position to the first position and removed, or the container can be rotated from the second position to the third position for extrusion. S6. When the container 3 rotates to the third position, the annular support 51 in the piston assembly rotates relative to the piston assembly under the action of the actuating part, so that the annular support 51 rotates from the fourth position to the fifth position and is locked to the piston assembly by the first latch. At this time, the piston assembly is disengaged from the bottom of the container 3, the push rod 25 is fixed to the piston assembly, and the cutter 43 remains fixed to the piston assembly; S7. Extrusion: The moving assembly drives the push rod 25 to move towards the container, and drives the piston assembly to move, thereby realizing material extrusion. S8. Reset II: After all extrusion is completed, the moving assembly resets to the end away from the container. S9. After all extrusion is completed, press the unlock button 64 of the unlocking component, which will drive the push rod 63 to move towards the container and the limiting lock block 651 to move away from the container. The push rod 63 moves and pushes the first lock to unlock, so that the annular support 51 rotates from the fifth position to the fourth position under the action of elasticity and enters the preparation mode. After the limiting lock block 651 moves down, it releases the circumferential limitation on the container 3. At this time, rotate the container and make it enter the first position, and the container 3 can be taken out.

[0035] Furthermore, in step S6, the side wall of the first receiving groove 2903 on the container placement seat 29 contacts the actuating part on the annular support 51 and blocks its forward path, thereby causing relative rotation between the annular support 51 and the piston assembly and entering the fifth position; in the fifth position, the second locking part 519 on the annular support 51 disengages from the second locking groove 321 at the bottom of the container and realizes the separation of the piston assembly from the bottom of the container; at the same time, the second receiving groove 510 on the inner wall of the annular support 51 is misaligned with the steel ball, and the inner wall of the annular support 51 presses the steel ball into the annular locking groove 251 on the side wall of the push rod 25, and realizes the fixed connection between the push rod 25 and the piston assembly.

[0036] Furthermore, when the annular support 51 is in the fourth position, the second snap-fit ​​portion 519 on the side wall of the annular support 51 is radially inserted into the second snap-fit ​​groove 321 at the bottom of the container, thereby axially fixing the piston assembly to the container 3; at the same time, the second receiving groove 510 on the inner wall of the annular support 51 is located outside the steel ball and can accommodate the steel ball, thereby losing the thrust on the steel ball and causing the steel ball to disengage from the annular snap-fit ​​groove 251 on the side wall of the push rod 25, thereby separating the push rod 25 from the piston assembly.

[0037] Furthermore, in step S9, after the unlocking component unlocks, the elastic force of the elastic auxiliary component generates a rotational force on the container to rotate towards the first position.

[0038] This invention relates to an integrated ice cream preparation and extrusion machine, which integrates ice cream preparation and extrusion functions into a single device. The entire process eliminates the need for container transfer, reducing operational steps and preventing contamination, leakage, or temperature changes during material transfer, thus ensuring stable product quality. Through the synergistic action of the moving assembly, piston assembly, and clutch mechanism, it achieves fully automated operation from raw material crushing and mixing to finished product extrusion, reducing the need for manual intervention, saving labor costs, and simultaneously improving production efficiency. This integrated ice cream preparation and extrusion machine features a compact structure, high space utilization, and is suitable for both home and commercial settings. Attached Figure Description

[0040] See Figures 1-28 This invention provides an integrated ice cream preparation and extrusion machine that can realize the automated preparation and extrusion of ice cream without moving the container.

[0041] The integrated extrusion machine mainly includes a body 1 and a container 3. The body 1 is provided with a container placement seat 29 and a moving assembly, and the container 3 is provided with a piston assembly 4 and a clutch mechanism 5.

[0042] The container placement seat 29 is used to place the container 3. Specifically, a placement hole 290 is formed on the container placement seat 29, which matches the bottom contour of the container 3 and can be stably embedded and limited at the bottom of the container 3.

[0043] The movable assembly is located at one end of the container placement seat 29 and can move towards or away from the container placement seat. Preferably, the movable assembly is located directly above or below the container placement seat 29. The movable assembly is provided with a push rod 25 and a main shaft 24. The main shaft 24 is coaxial with the push rod 25 and is rotatably mounted inside the push rod 25. The first end of the main shaft 24 serves as an output end, protruding outside the push rod 25, for connection with the cutter inside the container 3. The axes of the push rod 25 and the main shaft are parallel to the moving direction of the movable assembly, for realizing the preparation and extrusion of ice cream.

[0044] Container 3 is used to hold materials, which can be frozen dairy raw materials. Container 3 can be fixedly installed on container placement seat 29 and is detachable. After being fixedly placed, the container is coaxial with the main shaft and push rod.

[0045] The piston assembly 4 is installed inside the container 3. Specifically, it is slidably fitted inside the container 3 and can move axially. A sealing ring is provided between the side wall of the piston assembly 4 and the inner wall of the container 3. A blade 43 is provided on the piston assembly 3. The blade 43 is used to crush and stir the frozen material. At the same time, a shaft hole is provided in the center of the piston assembly 3 for the push rod 25 to pass through. The clutch mechanism 5 is installed inside the piston assembly 4. This clutch mechanism is used to control the engagement and disengagement between the piston assembly 4 and the bottom of the container 3, as well as between the push rod 25 and the piston assembly 4.

[0046] During preparation, the piston assembly 4 is fixed to the container 3, and the cutter 43 is disengaged from the piston assembly 4. At the same time, the push rod 25 is disengaged from the piston assembly 4. At this time, with the movement of the moving assembly and the rotation of the main shaft 24, the cutter 43 can rotate and move axially within the container 3. Specifically, with the rotation of the main shaft 24, the cutter rotates circumferentially. At the same time, in coordination with the movement of the moving assembly 4, the main shaft 24 moves, ultimately enabling the cutter to rotate circumferentially and move axially within the container, thereby crushing and mixing the material in all directions, ensuring that the raw materials are uniformly emulsified and form a delicate ice cream base. During extrusion, the piston assembly 4 disengages from the container 3, while the push rod 25 remains fixed to the piston assembly 4. At this time, the movement of the moving assembly drives the piston assembly to move axially, thus extruding the ice cream. During this process, the cutter 43 can be either loosened or fixed to the piston assembly 4. In the disengaged state, the cutter can connect to the shaft hole or the end of the main shaft under the action of the sealing ring between it and the shaft hole, the helical teeth between it and the main shaft, or magnetic attraction. To further improve operational reliability and prevent accidents, the cutter 43 can also be fixed to the piston assembly 4, maintaining a stable connection during any extrusion process and preventing complete disengagement of the cutter from the piston assembly due to external forces or the viscous resistance of the material during axial movement.

[0047] This application integrates ice cream preparation and extrusion functions into a single device, eliminating the need for container transfer throughout the process. This reduces operational steps and prevents contamination, leakage, or temperature changes during material transfer, ensuring consistent product quality. Through the synergistic action of the moving assembly, piston assembly, and clutch mechanism, fully automated operation is achieved from raw material crushing and mixing to finished product extrusion, reducing the need for manual intervention, saving labor costs, and simultaneously improving production efficiency.

[0048] During the preparation stage, the cutter can rotate circumferentially and move axially with the rotation of the spindle and the movement of the moving assembly, crushing and stirring the frozen material in the container from all directions and multiple angles. This movement mode can ensure that the raw materials are fully and evenly emulsified to form a delicate ice cream base, effectively avoiding the problems of clumping or uneven stirring, and improving the taste and texture of the ice cream.

[0049] By incorporating a clutch mechanism, the engagement and disengagement states between the piston assembly and the container, and between the push rod and the piston assembly, can be precisely controlled to meet the motion requirements of different stages of preparation and extrusion. During extrusion, the piston assembly disengages from the container, while the push rod remains fixed to the piston assembly. The push rod moves axially along with the moving assembly, achieving stable extrusion.

[0050] The ice cream preparation extrusion machine proposed in this application can not only save equipment space and reduce equipment investment costs, but also simplify the production process and improve overall operating efficiency and product quality, which will greatly promote the technological progress and development of the ice cream preparation industry.

[0051] The following provides a detailed description of each component in this application: As an important component for crushing and mixing materials, the cutter 43 has a cutter hole at its center facing the main shaft, which is used to connect with the end of the main shaft. At the same time, a connector 241 is provided at the end of the main shaft 24. The connector 241 corresponds to the cutter hole and can be inserted axially into the cutter hole. The side wall of the connector 241 is connected to the inner wall of the cutter hole by helical teeth 241. The helical teeth can transmit torque and achieve radial limiting. That is, when the main shaft 24 rotates, the cutter 43 can be driven to rotate through the helical teeth connection to achieve mixing. The inclination direction of the helical teeth 2411 is the same as the rotation direction of the main shaft 24. Therefore, when the main shaft 24 rotates, the action of the helical teeth can make the connection between the connector and the cutter hole tighter and prevent loosening due to vibration or resistance.

[0052] To further enhance the connection reliability between the cutter 43 and the spindle 24 and prevent the cutter from disengaging from the spindle 24 during stirring and axial movement, in this embodiment, the cutter 43 generates a thrust close to the spindle direction when rotating. This thrust is achieved through the tilting direction of the stirring blade on the cutter 43. The surface of the stirring blade forms a certain angle with the radial surface of the container. When the cutter rotates with the spindle, this angle design causes the cutter to generate an axial force close to the spindle direction during rotation, effectively enhancing the stability of the connection between the cutter and the spindle and preventing disengagement.

[0053] To achieve rapid docking, this application incorporates a magnet between the connector 241 and the cutter 43, enabling a magnetic connection. The magnet is positioned on the connector and within the cutter hole. When the cutter approaches the spindle end, the magnetic force guides the connector to automatically align and embed into the cutter hole, achieving rapid positioning and pre-fixation, effectively improving assembly efficiency. This magnetic connection ensures initial engagement stability without hindering the normal meshing of the helical gear structure. The combined effect of these two mechanisms ensures reliable connection of the cutter during high-speed rotation and axial movement, enhancing overall operational reliability and stability.

[0054] The cutting tool 43 in this application includes a cutting shaft and a blade body disposed on the cutting shaft. The cutting shaft is cylindrical and can be inserted into the shaft hole of the piston assembly. A sealing ring is provided in the shaft hole. The sealing ring can contact the outer wall of the cutting shaft or the outer wall of the push rod to achieve a seal. At the same time, the sealing ring provides friction to the cutting shaft to fix the cutting tool, that is, the cutting tool is fixed to the piston assembly by the sealing ring. The blade body is inclined to the radial surface, which on the one hand helps to generate axial thrust during rotation, enhances the tightness of the connection between the cutting tool and the main shaft, and on the other hand can effectively crush materials and promote uniform mixing. The cutting tool hole is opened at the bottom of the cutting shaft. As another embodiment, an annular groove 430 can be provided on the side wall of the cutting shaft. The annular groove 430 is used to connect with the clutch mechanism. Specifically, it is connected with the locking block 53 in the clutch mechanism, thereby axially fixing the cutting tool 43 to the piston assembly 4, so that it forms an integral part with the piston assembly, which is convenient for disassembly and maintenance.

[0055] There are two ways to engage and disengage the cutting tool and piston assembly: Method 1: The tool is fixed to the piston assembly by the frictional force generated by the sealing ring on the tool shaft; Method 2: The tool is fixed to the piston assembly by the locking block in the clutch mechanism and the annular groove on the side wall of the tool shaft.

[0056] In this application, the spindle connector and the cutter hole transmit torque through helical gear meshing, and the inclination direction of the helical gear end is consistent with the spindle rotation direction. When the spindle rotates, the force between the helical gears makes the connector and the cutter hole fit more tightly, effectively offsetting the vibration and material resistance generated during the stirring process. Structurally, this prevents the connection from loosening and ensures that the cutter always rotates synchronously with the spindle. The blade body is inclined on the radial surface, which can generate an axial thrust close to the spindle when rotating, further enhancing the tightness of the connection between the cutter and the spindle. Even when stirring at high speed or handling hard and frozen materials, it can effectively prevent the cutter from separating from the spindle, ensuring stable operation for a long time. At the same time, magnets are built into the connector and the cutter hole, which not only realize automatic alignment and pre-fixation of the cutter when it approaches the spindle, improving assembly efficiency, but also provide initial connection force before the helical gears mesh, avoiding connection misalignment caused by impact force at the moment of spindle start-up, thus providing double protection for connection reliability.

[0057] The inclined blade design not only generates axial thrust, but also cuts, impacts, and stirs materials at multiple angles during rotation. Combined with the axial movement of the spindle, it can pulverize and mix frozen materials in the container from all angles, ensuring that the raw materials are fully emulsified to form a fine and uniform ice cream base.

[0058] The cutting tool connects to the clutch mechanism via an annular groove or a sealing ring, allowing for quick axial fixation or separation from the piston assembly. This facilitates individual disassembly of the tool for cleaning, grinding, or replacement, reducing maintenance difficulty and time costs. A sealing ring is installed between the cutter shaft and the piston assembly shaft hole, effectively preventing material leakage and adapting to different movement states of the cutter shaft or push rod. This ensures sealing without affecting normal equipment operation and also provides tool fixation.

[0059] The moving assembly is used to move the push rod 25 and the main shaft 24 toward or away from the container. Preferably, the moving assembly is vertically arranged and can be located at the upper or lower end of the container. It includes a slide 22 slidably fitted below the container placement seat 29 via multiple guide rods 21, and a slide drive mechanism for driving the slide 22 to move. The push rod 25 is vertically fixed to the slide 22. The push rod 25 includes two sections: a smooth rod section at the head that can pass through the shaft hole of the piston assembly and extend into the container during the manufacturing process, and a threaded rod end at the tail with external threads on the side wall as the driving end. The slide drive mechanism includes a screw sleeve 262 and a slide drive motor 27. The screw sleeve 262 is cylindrical in shape and has internal threads on its inner wall, which mesh with the threaded rod end of the push rod. The screw sleeve is rotatably installed. The slide drive motor 27 is used to drive the screw sleeve 262 to rotate, thereby driving the slide to move axially. In this application, the slide drive mechanism also includes a first mounting base 261, which is fixed to the end of the container placement base 29. A threaded sleeve 262 is rotatably mounted in the first mounting base 261, and a slide drive motor 27 is also mounted on the first mounting base 261. The output end of the slide drive motor 27 is connected to the threaded sleeve 262. Specifically, a gear ring 263 is provided on the side wall of the threaded sleeve 262, and a drive gear 271 is provided on the output end of the slide drive motor 27. The drive gear 271 meshes with the gear ring 263 and can drive the threaded sleeve 262 to rotate.

[0060] A main spindle motor 23 is provided on the slide 22. The output end of the main spindle motor 23 is connected to the main spindle 24 through a reduction mechanism 221 to drive the main spindle 24 to rotate. Specifically, the main spindle 24 is coaxial with the push rod 25 and is rotatably installed inside the push rod 25. The lower end of the main spindle 24 extends into the slide. The reduction mechanism 221 is set inside the slide and connected to the tail end of the main spindle to realize power transmission.

[0061] In this application, a transmission method is adopted in which the threaded rod at the tail of the push rod meshes with the internal thread of the screw sleeve. Compared with transmission structures such as chains and belts, the screw drive has higher transmission accuracy and can accurately control the displacement of the slide. This ensures that the push rod and the main shaft achieve precise axial movement during the preparation and extrusion process, guaranteeing the uniformity of the blade stirring during ice cream preparation and the stability of the piston movement during extrusion. It also requires less installation space. The slide drive motor drives the screw sleeve to rotate through the meshing of the drive gear with the gear ring on the side wall of the screw sleeve. The gear drive has high transmission efficiency and large torque, which can provide sufficient power for the movement of the slide. Even when handling harder frozen materials or extruding viscous ice cream, it can ensure smooth and reliable movement and avoid jamming or insufficient power.

[0062] In order to achieve rapid and accurate radial positioning of container 3 on container placement seat 29, in this application, container 3 is detachably fixed to container placement seat 29 by a plurality of first buckles, and the first buckles are unevenly distributed and / or at least one first buckle is different in size from the other first buckles, thereby enabling radial positioning when container 3 is inserted into container placement seat 29.

[0063] In this embodiment, a plurality of first snap-fit ​​slots 2902 are provided on the container placement base 29. The plurality of first snap-fit ​​slots 2902 are distributed in an uneven manner on the circumference of the container placement base 29, or at least some of the first snap-fit ​​slots 2902 have different dimensions from the rest of the first snap-fit ​​slots 2902. At the same time, the container is provided with a first snap-fit ​​part 36 corresponding to the first snap-fit ​​slot 2902, thereby forming a unique positioning and matching structure to ensure that the container can only be installed in the correct position when placed.

[0064] When container 3 is placed on container base 29, it can rotate between a first position, a second position, and a third position. In the first position, container 3 can be detached from container base 29; that is, the first position is used for the installation and removal of container 3. In the second position, it is in the preparation station; at this time, piston assembly 4 is fixed to container 3, push rod 25 is disengaged from piston assembly 4, and cutter 43 can be disengaged from piston assembly 4, allowing for preparation operations. In the third position, it is in the extrusion station; at this time, piston assembly 4 is disengaged from container 3, and push rod 25 is fixed to piston assembly 4.

[0065] This application utilizes a multi-position rotation design of the container on a container stand. The rotation of the container controls the internal clutch mechanism, allowing for switching of functional states between different workstations and achieving orderly linkage between installation, preparation, and extrusion. Each time the container rotates to a specific position, its internal clutch mechanism automatically responds according to the positioning structure, connecting or disengaging internal components to ensure that each stage of action is independent and precisely executed. This design not only improves operational convenience but also effectively avoids equipment damage or preparation failures caused by misoperation, significantly improving equipment reliability and user experience. Through the ingenious coordination of the mechanical structure, automatic switching between workstations is achieved without additional control components, reducing system complexity and manufacturing costs.

[0066] In this application, the clutch mechanism 5 has two embodiments. In one embodiment, the clutch mechanism 5 includes a second clutch assembly and a third clutch assembly. The second clutch assembly is used to engage (connect or disengage) the piston assembly 4 and the push rod 25, and the third clutch assembly is used to engage (connect or disengage) the piston assembly 4 and the container 3. In this embodiment, the cutter is fixed to the piston assembly by the friction force generated by the sealing ring on the cutter shaft. When ejecting, the force provided by the push rod is greater than the friction force.

[0067] In another embodiment, which differs from the above embodiments, the clutch mechanism further includes a first clutch assembly for engaging or disengaging the tool 43 from the piston assembly 4. Specifically, the first clutch assembly is radially slidably mounted within the piston assembly 4, and is used to lock the tool 43, thereby achieving an axial fixed connection between the tool 43 and the piston assembly 4.

[0068] The clutch mechanism 5 includes an annular support 51, which is an overall annular structure and is rotatably mounted inside the piston assembly 4 and coaxial with the piston assembly 4. The annular support 51 is provided with an actuating part 551, a first locking buckle 52, a second clutch assembly, and a third clutch assembly. The actuating part 551 is a protruding structure used to actuate the annular support from a fourth position to a fifth position, and the end of the actuating part 551 extends outside the piston assembly. The first locking buckle 52 is used to lock and fix the annular support 51 to the piston assembly 4 when rotated to the fifth position, achieving relative fixation between the annular support 51 and the piston assembly 4. The second clutch assembly... The first component is used to lock the push rod 25 when rotated to the fifth position, so that the push rod 25 is fixed to the piston assembly 4; the third clutch assembly is used to lock the lower cover of the container 3 in the fourth position, so that the piston assembly is fixed to the bottom of the container; at the same time, the container placement seat 29 is provided with a first trigger and an unlocking assembly, wherein the first trigger is used to contact the actuating part 551 when the container 3 rotates from the second position to the third position, and generate relative rotation, thereby actuating the annular support 51 from the fourth position to the fifth position; the unlocking assembly is used to unlock the first latch 52, thereby causing the annular support 51 to return from the fifth position to the fourth position under the action of elastic force.

[0069] The aforementioned first trigger is a first receiving groove 2903 disposed in the container placement seat 29. Specifically, it is disposed on the bottom surface of the placement hole 290 of the container placement seat 29, and is an arc-shaped groove used to accommodate the actuating part 551. The side wall of the first receiving groove 2903 forms a contact surface, which is used to contact the side wall of the actuating part 551, so that the annular support 51 and the piston assembly rotate relative to each other, thereby forming a actuating action.

[0070] A through hole 2904 is provided on the bottom surface of the container placement seat 29, through which the top rod 63 passes axially. In this embodiment, the through hole 2904 is located in the first receiving groove 2903.

[0071] An elastic component is provided inside the piston assembly, which tends to reset the annular support 51 to the fourth position. Specifically, one or more spring mounting seats 511 are provided on the side wall of the annular support 51, and a tension spring is provided between the spring mounting seat 511 and the inner wall of the piston assembly. Through the elastic force of the tension spring, the annular support 51 is stably in the fourth position when there is no external interference.

[0072] Correspondingly, a second latch 541 is provided within the piston assembly. When the annular support is in the fifth position, the first latch 52 and the second latch 541 are engaged, thereby fixing the annular support 51 in the fifth position. The second latch 541 is an elastic latch. The unlocking component can push the first latch 52 or the second latch 541 to move or rotate and unlock, that is, it can disengage the first latch 52 from the second latch 541, thereby releasing the annular support 51 and allowing it to automatically return to the fourth position under the action of the tension spring.

[0073] Specifically, the first latch 52 is mounted on the annular support 51 and can move axially. The end of the first latch 52 is provided with an unlocking contact 521, which extends to the outside of the piston assembly. The unlocking component can contact the unlocking contact 521 and push the first latch to move axially, thereby disengaging from the second latch 541 and triggering the unlocking action. At the same time, the first latch 52 is provided with an elastic reset component, which is a spring. After the unlocking component completes the push triggering of the unlocking contact, that is, after being lifted, the first latch 52 quickly resets under the action of the spring, ensuring that the mechanism returns to the initial standby state.

[0074] To improve the installation stability of the container on the container placement seat 29, this application provides a limiting lock block 651 on the container placement seat 29. The limiting lock block 651 is an elastic limiting lock block 651, which is used to circumferentially limit the container 3, thereby fixing the container in a second position or a third position. The limiting lock block 651 is provided with an inclined guide surface, which allows the container to rotate unidirectionally from the first position to the second position, or from the second position to the third position. At the same time, the container is provided with a locking hole 361 that can accommodate the limiting lock block 651 and achieve axial fixation. The above-mentioned unlocking component can also unlock the limiting lock block 651 to unlock the position of the container.

[0075] The unlocking assembly includes a slider 65 and unlocking buttons 64 and a push rod 63 located at both ends of a lever 62. The slider can slide axially in a direction parallel to the sliding direction of the piston assembly. The upper end of the slider 65 has a protrusion forming a circumferential limiting lock block 651 for the container. One side of the limiting lock block has an inclined surface forming an inclined guide surface, and the other side is a locking surface. This ensures that when the container rotates from the first position to the second position or from the second position to the third position, it cannot return from the second position to the first position or from the third position to the second position, thus ensuring one-way locking of the container during rotation.

[0076] The aforementioned push rod 63 can move axially, with its sliding direction parallel to the container's axis. It is used to unlock the first latch, i.e., to lift the unlocking contact block, thereby moving the first latch 52 and disengaging it from the second latch 541. A protrusion 652 is provided on the side wall of the slider 65, and a pressure block 641 is provided on the side wall of the unlocking button 64. The pressure block 641 can contact the top surface of the protrusion 652 to press down the slider. When the unlocking button 64 is pressed, the lever 62 rotates around the fulcrum, and the push rod 63 is lifted towards the container, unlocking the first latch 52. Simultaneously, as the unlocking button 64 is pressed, the pressure block 641 on its side wall presses down on the protrusion of the slider 65, causing the slider 65 to move away from the container, thereby driving the limiting locking block 651 to overcome the elastic force and move away from the container, disengaging it from the lock hole 361 on the container, thus unlocking the container circumferentially. At this time, the container can be rotated in the opposite direction to the first position and removed.

[0077] The unlocking assembly also includes elastic reset components, which are used to reset the push rod 63 away from the container, the slider 65 towards the container, and the unlock button 64 towards the container. Specifically, it also includes an unlocking support 61 as a mounting carrier, on which the lever 62 is rotatably mounted. The elastic reset components include a first spring 631, a second spring 653, and a third spring 643. The first spring 631 is used to reset the push rod 63 away from the container, the second spring 653 is used to reset the slider 65 towards the container, and the third spring 643 is used to reset the unlock button 65 towards the container. The use of multiple reset components ensures that each functional component resets independently without interference, improving the stability and response accuracy of the unlocking mechanism, avoiding unlocking failures caused by reset delays or jamming, and ensuring smooth and reliable operation.

[0078] To facilitate user operation and make container disassembly more effortless and efficient, this application includes an elastic auxiliary component on the container placement base 29. This elastic auxiliary component allows the container 3 to tend to move in the unlocking direction, or even to rotate back to the first position. Specifically, the elastic auxiliary component includes an elastic push block 292 that slides on the side wall of the placement hole 290 of the container placement base 29, with its sliding direction tangential to the inner wall of the placement hole. A spring is located at its rear end. Simultaneously, a support block is provided on the side wall of the container 3 for contacting the elastic push block. When the container rotates from the first position to the second position, or from the second position to the third position, the elastic auxiliary component is compressed and stores energy. When the unlock button is triggered, the spring releases energy, pushing the slider tangentially along the inner wall of the placement hole, driving the container to rotate in the opposite direction and reset. This design makes the unlocking process effortless and smooth, improving operational convenience and structural response accuracy.

[0079] The actuating part can also be adopted in another embodiment, the difference being that in this embodiment, the end of the unlocking contact 521 extends axially to the outside of the piston, and at the same time serves as the actuating part, its side wall is the actuating surface, that is, the unlocking contact 521 and the actuating part are an integral structure; when unlocking is required, the unlocking contact is pushed axially to achieve unlocking; when rotating, the side wall of the unlocking contact 521, that is, the actuating part, contacts the trigger on the ice cream machine, thereby actuating the annular support to rotate.

[0080] In an embodiment with a first clutch assembly, the first clutch assembly includes a locking block 53 radially slidably fitted within the piston assembly 4 and a first elastic member 533 that causes the locking block 53 to have an inward tendency to move. The locking block 53 is provided with a first engaging portion 531 and a first pushing portion 532 that can extend into the shaft hole. The first pushing portion 532 is located at the lower end of the first engaging portion 531. The first engaging portion 531 can be radially engaged into the annular groove 430 on the side wall of the tool shaft of the tool 43 to achieve axial fixation of the tool 53. The first pushing portion 532 can accommodate the push rod 24 to push it open and achieve unlocking of the first clutch assembly. Therefore, a chamfer is provided at the end of the first pushing portion or the end of the push rod 24. When the push rod 24 moves toward the container, the chamfer pushes the first pushing portion to move radially outward, causing the entire locking block to move outward, thereby causing the first engaging portion to disengage from the annular groove on the side of the tool shaft and achieving unlocking of the tool.

[0081] The second clutch assembly includes a first connector disposed within the shaft hole of the piston assembly and capable of being triggered by an annular support; when the annular support is in the fifth position, it can trigger the first connector to move and connect with the second connector on the push rod sidewall, thereby achieving a fixed connection between the push rod and the piston assembly; when the annular support is in the fourth position, it triggers the first connector to move in the opposite direction and disengage from the second connector on the push rod sidewall, thereby achieving separation between the push rod and the piston assembly.

[0082] In this embodiment, the first connector is a receiving groove and a locking member that can be located in the receiving groove, and the second connector is a groove structure provided on the side wall of the push rod.

[0083] Specifically, the second clutch assembly includes a steel ball 58 disposed on the side wall of the shaft hole of the piston assembly and a second receiving groove 510 disposed on the inner wall of the annular support 51. When the annular support 51 is in the fourth position, the second receiving groove 510 is located just outside the steel ball and can accommodate the steel ball. At this time, the steel ball cannot lock the push rod. When the annular support 51 is in the fifth position, the second receiving groove 510 is misaligned with the steel ball, and the inner wall of the annular support 51 and the steel ball structure press the steel ball into the annular groove 251 on the side wall of the push rod 25, thereby achieving axial fixation of the push rod and the piston assembly.

[0084] The third clutch assembly includes a second engaging portion 519 disposed on the side wall of the annular support 51. When the annular support 51 rotates to the fourth position, the second engaging portion 519 can engage into the second slot 321 at the bottom of the container, thereby achieving axial fixation with the lower cover of the container. When the annular support 51 returns to the fifth position, the second engaging portion 519 disengages from the second slot 321 on the lower cover of the container, at which point the axial fixation between the piston assembly and the lower cover of the container is released.

[0085] In this application, the piston assembly 4 includes an upper piston body 42 and a lower piston body 41 connected to each other. A cavity is formed between the upper piston body 42 and the lower piston body 41 as a mounting cavity for mounting the clutch mechanism 5. An arc-shaped hole and a first slot 411 are provided on the lower piston body 41. The arc-shaped hole can accommodate the axial extension of the actuating part on the clutch mechanism 5 and provide space for its rotation. The first slot 411 can accommodate the axial insertion of the second slot 321 on the lower cover of the container to achieve circumferential limiting. At the same time, it can accommodate the radial insertion of the second locking part 519 on the clutch mechanism 5 to achieve axial limiting and fixing.

[0086] To improve the level of automation, this application also includes multiple forming switches for detecting the height position of the moving assembly. In this embodiment, there are three forming switches, which are used from top to bottom to detect the upper limit position, the spindle start position, and the lower limit position of the slide. During the manufacturing process, i.e. when the spindle rotates, the spindle rotates between the upper limit position and the spindle start position. It does not rotate below the spindle start position, which facilitates the tool reset and prevents the tool from entering the shaft hole during rotation, thus avoiding equipment damage or safety hazards.

[0087] The container in this application includes a cylindrical body 31 with open ends, an upper cover 33 installed on the upper end of the cylindrical body 31, and a lower cover 32 installed on the lower end of the cylindrical body 31. The lower cover is the cover near the push rod end, and the upper cover is the cover away from the push rod end. The top surface of the lower cover 32 is provided with a plurality of protruding second slots 321. The second slots 321 can be axially inserted into the first slot 411 at the bottom of the piston assembly, and are also used for radial engagement with the second engagement part 519 on the clutch mechanism. A central hole for the push rod to pass through is provided on the lower cover 32 and the receiving and placing seat.

[0088] Meanwhile, the present invention also provides a method for operating an integrated ice cream extrusion machine, which includes the following steps: S1. Loading: Insert the container 3 containing the material into the placement hole 290 of the container placement seat 29 at the first position, and rotate it to the second position to fix it. At this time, the piston assembly is located at the very end of container 3, and its bottom is fixed to the bottom of container 3. At the same time, the push rod 25 is disengaged from the piston assembly, and the cutter 43 is also disengaged from the piston assembly. At this time, the annular support 51 is in the fourth position, and the second snap-fit ​​part 519 on the side wall of the annular support 51 is radially inserted into the second snap-fit ​​groove 321 at the bottom of the container, thereby axially fixing the piston assembly to the container 3; at the same time, the second receiving groove 510 on the inner wall of the annular support 51 is located outside the steel ball and can accommodate the steel ball, thereby losing the thrust on the steel ball and causing the steel ball to disengage from the annular snap-fit ​​groove 251 on the side wall of the push rod 25, thereby separating the push rod 25 from the piston assembly; S2, Preparation: The moving assembly moves axially, driving the push rod 25 and the main shaft 24 to move synchronously. During the process of the push rod 25 approaching the container in the initial reset state, the push rod overcomes the friction of the sealing ring on the cutter and lifts the cutter, causing the cutter to disengage from the piston assembly; or the push rod can push outward to open the locking block 53 used to lock the cutter 43 and realize the automatic disengagement of the cutter 43 from the piston assembly. At the same time, the spindle 24 rotates. During the axial movement and rotation of the spindle 24, it is connected to the tool 43 through the helical teeth at its end and drives the tool 43 to rotate. The helical teeth provide the tool 43 with a radial force for circumferential rotation and a pulling force to move closer to the push rod. S3. By moving the moving assembly axially, the cutter 43 rotates and moves axially within the container 3, thereby crushing and mixing the material within the container 3. S4. Reset I: After one or more mixing and crushing operations, the moving assembly is reset to the end away from the container, and the main shaft 24 stops rotating. As the moving assembly resets, the tool shaft returns to the shaft hole and is fixed to the piston assembly by the friction of the sealing ring; or as the moving assembly resets, the push rod disengages from the locking block, and the locking block moves radially inward under the action of the elastic force and locks the tool 43, thereby fixing the tool. To prevent the tool from rotating into the shaft hole during the reset process and causing equipment damage or safety risks, the spindle stops rotating when it descends below the spindle start position to ensure that the tool remains stationary during the reset process; S5. After preparation is complete, container 3 can be rotated from the second position to the first position and removed, or the container can be rotated from the second position to the third position for extrusion. S6. When the container 3 rotates to the third position, the annular support 51 in the piston assembly rotates relative to the piston assembly under the action of the actuating part, so that the annular support 51 rotates from the fourth position to the fifth position and is locked to the piston assembly by the first latch. At this time, the piston assembly is disengaged from the bottom of the container 3, the push rod 25 is fixed to the piston assembly, and the cutter 43 remains fixed to the piston assembly; Specifically, the side wall of the first receiving groove 2903 on the container placement seat 29 contacts the actuating part on the annular support 51 and blocks its forward path, thereby causing relative rotation between the annular support 51 and the piston assembly and entering the fifth position; in the fifth position, the second locking part 519 on the annular support 51 disengages from the second locking groove 321 at the bottom of the container and realizes the separation of the piston assembly from the bottom of the container; at the same time, the second receiving groove 510 on the inner wall of the annular support 51 is misaligned with the steel ball and the inner wall of the annular support 51 presses the steel ball into the annular locking groove 251 on the side wall of the push rod 25, realizing the fixed connection between the push rod 25 and the piston assembly; S7. Extrusion: The moving assembly drives the push rod 25 to move toward the container and drives the piston assembly to move, thereby realizing material extrusion. During extrusion, the moving assembly is triggered to move axially by pulling the handle 13 on the side wall of the motor body 1, thereby realizing extrusion. After releasing the handle 13, the moving assembly stops moving. S8. Reset II: After all extrusion is completed, the moving assembly resets to the end away from the container. S9. After all extrusion is completed, press the unlock button 64 of the unlocking component, which will drive the push rod 63 to move towards the container and the limiting lock block 651 to move away from the container. The push rod 63 moves and pushes the first lock to unlock, so that the annular support 51 rotates from the fifth position to the fourth position under the action of elasticity and enters the preparation mode. After the limiting lock block 651 moves down, it releases the circumferential limitation on the container 3. At this time, rotate the container and make it enter the first position, and the container 3 can be taken out. Once the unlocking component unlocks, the elastic force of the elastic auxiliary component generates a rotational force on the container, causing it to rotate toward the first position.

[0089] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.

8. The ice cream preparation and extrusion integrated machine as described in claim 1, characterized in that: The third clutch assembly includes a second locking part disposed on the side wall of the annular support; when the annular support is rotated to the fourth position, the second locking part can be locked into the second slot at the bottom of the container and achieve axial fixation.

9. The ice cream preparation and extrusion integrated machine as described in claim 1, characterized in that: The cutting tool includes a cutting shaft and a cutting blade body disposed on the cutting shaft. The cutting shaft is cylindrical and can be inserted into the shaft hole of the piston assembly. A sealing ring is provided in the shaft hole. The sealing ring can contact the outer wall of the cutting shaft to achieve sealing and provide friction for the cutting shaft.

10. A method for operating an integrated ice cream preparation and extrusion machine, characterized in that, Includes the following steps: S1. Loading: Insert the container containing the material into the placement hole of the container placement seat at the first position, and rotate it to the second position to fix it. At this point, the bottom of the piston assembly is fixed to the bottom of the container and the push rod is disengaged from the piston assembly; S2, Preparation: The moving assembly moves axially, driving the push rod and main shaft to move synchronously. As the push rod approaches the container, it disengages the cutter from the piston assembly. At the same time, the spindle rotates. During the movement and rotation of the spindle, it is connected to the tool through the helical teeth at its end and drives the tool to rotate. The helical teeth provide the tool with a radial force for circumferential rotation and a pulling force to move towards the push rod. S3. By rotating and moving the cutter axially within the container, the material inside the container is crushed and stirred. S4. Reset I: After one or more mixing and crushing operations, the moving assembly resets to the end away from the container, and the main shaft stops rotating. As the moving assembly resets, the tool is fixed on the piston assembly; S5. After preparation is complete, the container can be rotated from the second position to the first position and removed, or the container can be rotated from the second position to the third position for extrusion. S6. When the container rotates to the third position, the annular support inside the piston assembly rotates relative to the piston assembly under the action of the actuating part, causing the annular support to rotate from the fourth position to the fifth position and lock with the piston assembly through the first latch. At this point, the piston assembly disengages from the bottom of the container and the push rod is fixed to the piston assembly; S7. Extrusion: The moving assembly drives the push rod to move towards the container, and drives the piston assembly to move, thereby realizing the extrusion of materials. S8. Reset II: After all extrusion is completed, the moving assembly resets to the end away from the container. S9. Unlock: Press the unlock button on the unlocking component, which will drive the top rod to move towards one end of the container and the limiting lock block to move away from the container. The top rod moves and pushes the first lock to unlock, so that the ring support rotates from the fifth position to the fourth position under the action of elasticity and enters the preparation mode. After the limiting lock block moves down, it releases the circumferential limitation on the container. At this time, rotate the container and let it enter the first position to take out the container.
