Description

Technical Field

[0001] This utility model belongs to the field of food processing technology, and specifically relates to an ice cream machine. Background Technology

[0002] An ice cream machine is a common piece of equipment that cools, churns, overflushes, and extrudes mixed ingredients. A traditional ice cream machine typically includes a hopper for holding the ingredients, a churning evaporator for churning and cooling, and a dispensing unit.

[0003] The lack of effective crushing capacity makes it impossible to directly add solid ingredients such as chunks of fresh fruit, nuts, and biscuits. This results in ice cream with a limited range of flavors, failing to meet the growing demand of modern consumers for personalized ice cream with real fruit pieces and rich textures. When it is necessary to change the flavor of ice cream, the residual ingredients inside the traditional equipment must be removed. Since there is no built-in automatic cleaning system, this process relies entirely on manual labor, which is cumbersome and extremely incomplete. Utility Model Content

[0004] The purpose of this invention is to provide an ice cream machine that addresses the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An ice cream machine, including a top plate,

[0007] The main body of the equipment is located below the top plate, and a base is located below the main body of the equipment. An ice cream additive stirring, crushing and mixing mechanism is installed inside the main body of the equipment.

[0008] The ice cream topping mixing and pulverizing mechanism includes a mixer and a hopper. The mixer includes a mixing shaft blade, a mixing shaft core, a shaft core spring, a conical spiral mixing shaft, a mixing shaft sleeve, a sleeve pin, a lower bearing seat, a central shaft, an upper bearing seat, and a pulley. A stepper motor is installed inside the top plate, and the output end of the stepper motor is engaged with the pulley.

[0009] The hopper is in the shape of a triangular cone cup. A shaping piece is provided at the bottom of the hopper. The surface of the shaping piece is provided with a spline groove. The shaping piece is snapped onto the surface of the base through the spline groove. A discharge hole is provided at the bottom of the hopper. A through hole is provided on the side of the hopper. A water pipe is connected inside the through hole. A lifting assembly is connected to the side of the hopper.

[0010] As a preferred embodiment of this utility model, a conical blade shaft is provided in the middle of the stirring shaft, and a three-lobed blade is provided on the surface of the conical blade shaft.

[0011] In a preferred embodiment of this utility model, the top of the stirring shaft core and the core spring are connected to the stirring shaft spring pin inside the central shaft, and the bottom of the stirring shaft core and the core spring are connected to the stirring shaft blade. The outer surface of the stirring shaft sleeve is designed with a groove track, and the groove pin of the conical spiral stirring shaft can slide upward and rotate along the groove track, and finally engage with the surface of the stirring shaft sleeve.

[0012] As a preferred embodiment of this utility model, the conical spiral stirring shaft is inverted triangular in shape and has the same inner diameter as the hopper. The spiral blades of the conical spiral stirring shaft have several sharp notches.

[0013] In a preferred embodiment of this utility model, a handle is rotatably mounted on the side of the main body of the equipment, and a motor start switch is connected to the top of the handle. The lifting assembly includes a screw, the output end of the motor is fixedly connected to the screw, and the handle of the hopper is threaded onto the surface of the screw.

[0014] As a preferred embodiment of this utility model, a water pipe is provided on the back of the main body of the device, and the other end of the water pipe is connected to a water pump.

[0015] As a preferred embodiment of this utility model, a U-shaped transparent screen is provided around the conical spiral stirring shaft, and the diameter of the U-shaped transparent screen is slightly larger than the outer diameter of the hopper.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the synergistic action of the sharp notches on the spiral blades of the conical spiral stirring shaft and the three-bladed stirring shaft blades, the blocky raw materials such as fruits, nuts, and biscuits are effectively cut and crushed during the stirring process, so that they are fully and quickly mixed with the ice cream base. The inverted triangular conical spiral stirring shaft gradually fits into the inner wall of the hopper, generating strong extrusion and shearing forces, ensuring that even hard raw materials can be crushed and evenly mixed. At the same time, the hopper is lifted by the screw lifting assembly, and the stirring is started by the handle switch when it reaches a certain height, realizing the automatic linkage of mechanical actions. The side of the hopper has a through hole and is connected to a water pipe with a water pump and switch, which can directly spray clean water into the hopper.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example

[0027] Reference Figure 1-4 This is an embodiment of the present invention, which provides an ice cream machine, including a top plate 1.

[0028] The main body of the equipment is located below the top plate 1, and the base 2 is located below the main body of the equipment. The ice cream auxiliary material stirring, crushing and mixing mechanism is installed inside the main body of the equipment.

[0029] The ice cream topping mixing and pulverizing mechanism includes a mixer and a hopper 13. The mixer includes a mixing shaft blade 12, a mixing shaft core 10, a shaft core spring 11, a conical spiral mixing shaft 9, a mixing shaft sleeve 6, a sleeve pin, a lower bearing seat 5, a central shaft 4, an upper bearing seat, and a pulley. A stepper motor is installed inside the top plate 1, and the output end of the stepper motor is matched with the pulley.

[0030] The hopper 13 is in the shape of a triangular cone cup. A shaping piece 14 is provided at the bottom of the hopper 13. A spline groove is provided on the surface of the shaping piece 14. The shaping piece 14 is snapped onto the surface of the base 2 through the spline groove. A discharge hole is provided at the bottom of the hopper 13. A through hole is provided on the side of the hopper 13. A water pipe is connected inside the through hole. A lifting component is connected to the side of the hopper 13.

[0031] In use, the stepper motor in the top plate 1 drives the pulley, which in turn drives the central shaft 4 to rotate, thereby driving the entire mixer to run. The hopper 13 is a triangular conical cup shape with a discharge hole and a shaping plate 14 at the bottom. The shaping plate 14 is snapped onto the base 2 through a spline groove to ensure the stability and replaceability of the discharge port. The through hole on the side of the hopper 13 is connected to a water pipe for cleaning, and the side is also connected to a lifting component.

[0032] In summary, the overall structure is compact, with the top plate 1, the main body of the equipment, and the base 2 forming a stable support, which improves the stability and durability of the equipment. The shaping piece 14 is snapped together by a spline groove, which facilitates quick replacement of different shaped discharge ports, realizing diversified ice cream shapes and enhancing the user experience. The inverted conical design of the hopper 13 matches the conical spiral stirring shaft 9, optimizing material flow and reducing residue.

[0033] Furthermore, a conical blade shaft is provided in the middle of the stirring shaft 12, and a three-lobed blade is provided on the surface of the conical blade shaft.

[0034] When in use, the blade shaft corresponds to the hole on the shaping plate 14 when the mixer is running, but the diameter is smaller than the hole diameter, allowing the trilobal blade to perform preliminary cutting and crushing of the lumpy raw materials when rotating. The trilobal blade design improves cutting efficiency and can quickly crush hard raw materials to ensure a delicate texture for ice cream. The cooperation between the conical blade shaft and the shaping plate 14 avoids clogging and ensures smooth discharge.

[0035] Furthermore, the top of the stirring shaft core 10 and the core spring 11 are connected to the stirring shaft spring pin inside the central shaft 4, and the bottom of the stirring shaft core 10 and the core spring 11 are connected to the stirring shaft blade 12. The outer surface of the stirring shaft sleeve 6 is designed with a groove track 7, and the groove pin 8 of the conical spiral stirring shaft 9 can slide upward and rotate along the groove track 7, and finally engage with the surface of the stirring shaft sleeve 6.

[0036] During use, the outer surface of the stirring shaft sleeve 6 is provided with a groove track 7. The groove pin 8 of the conical spiral stirring shaft 9 can slide upward and rotate along the groove track 7, and finally engage with the stirring shaft sleeve 6 to complete the installation. The shaft core spring 11 provides elastic pressure, so that the stirring shaft cutter 12 and the shaping plate 14 maintain appropriate pressure when in contact, which enhances the cutting effect. The design of the groove track 7 and the groove pin 8 makes installation and disassembly simple and maintenance convenient, reducing the equipment assembly time. This connection method ensures the smoothness and quietness of the stirrer during operation.

[0037] Furthermore, the conical spiral stirring shaft 9 is inverted triangular in shape and has the same inner diameter as the hopper 13. The spiral blades of the conical spiral stirring shaft 9 have several sharp notches.

[0038] When in use, as the conical spiral mixing shaft 9 rotates, the notches perform secondary cutting and mixing of the raw materials, while simultaneously pushing the materials toward the discharge hole. The sharp notches on the spiral blades can effectively crush lumpy raw materials, such as fruits and nuts, making the mixing more uniform. The inverted triangular design fits the inner wall of the hopper 13, reducing material residue and improving the utilization rate of raw materials. The rotation of the conical spiral mixing shaft 9 generates a squeezing effect, causing the ice cream to be evenly discharged from the discharge hole, resulting in a better taste.

[0039] Furthermore, a handle 3 is rotatably mounted on the side of the main body of the equipment. The top of the handle 3 is connected to a motor start switch. The lifting assembly includes a screw. The output end of the motor is fixedly connected to the screw. The handle of the hopper 13 is threaded onto the surface of the screw.

[0040] When in use, turning the handle 3 moves the material hopper 13 up and down. When the material hopper 13 rises to a certain height, the motor is started by the motor start switch at the top of the handle 3. At this time, the screw rotates, and the output end of the stepper motor and the pulley drive the conical spiral mixing shaft 9 to start rotating, thereby cleaning the conical spiral mixing shaft 9. The design includes a motor switch that can be started and stopped as needed, making it easier for the equipment operator to start or stop the mixing action of the equipment at any time, making it more convenient to use.

[0041] Furthermore, a water pipe is installed on the back of the main body of the equipment, and the other end of the water pipe is connected to a water pump.

[0042] During use and cleaning, turn on the water pump switch, and water is injected into the hopper through the through hole to rinse the inner wall of the conical spiral mixing shaft 9 and the hopper 13. The wastewater is discharged from the bottom discharge hole. This function reduces the trouble of manual cleaning, saves time and water resources, and the cleaning process is efficient, meets hygiene standards, and is suitable for continuous production.

[0043] Furthermore, a U-shaped transparent screen is provided around the conical spiral stirring shaft 9, and the diameter of the U-shaped transparent screen is slightly larger than the outer diameter of the hopper 13.

[0044] When in use, the U-shaped transparent screen prevents water or material from splashing during the mixing process, keeping the operating environment clean. The transparent material allows users to observe the mixing process, enhancing interactivity and safety.

[0045] Furthermore, the main body of the equipment features a six-support column design on both the left and right sides. Two of these columns not only provide support but also serve as sliding rods for lifting the hopper 13. A slider is installed at the end of the hopper 13, which is fitted onto the sliding rod to assist in lifting the hopper 13. The sliding rod has a smooth surface, preventing jamming during the lifting process of the hopper 13 and ensuring more stable operation. Additionally, two support columns are installed between the top plate 1 and the base 2, making the main body of the equipment more stable during operation and preventing vibration.
