Description

Technical Field

[0001] This invention relates to the field of ice cream machine technology, and specifically to an ice cream machine. Background Technology

[0002] Currently, most ice cream machines on the market use two motors to control the rotation and lifting of the blade assembly, which is relatively complex, costly, and large in size.

[0003] The invention patent with patent publication number CN117752007A discloses an ice cream machine. This prior art uses a single motor with dual output shafts to provide two power outputs. The first output shaft is connected to the cutter shaft for driving the cutter shaft to rotate; the second output shaft is connected to the lead screw lifting mechanism for driving the lifting platform to lift the cutter shaft. Its structure is relatively complex and the whole machine is relatively large.

[0004] Therefore, there is still room for improvement and development in existing technologies. Summary of the Invention

[0005] To address the problems of existing technologies, this invention proposes an ice cream machine that uses a single-axis motor in conjunction with a cutter shaft rotation assembly and a cutter shaft lifting assembly to drive the cutter shaft assembly to rotate and lift. This results in a simpler structure, lower cost, and a smaller overall product size.

[0006] To achieve the above objectives, the technical solution applied in this invention is as follows: An ice cream machine includes a main unit with a drive motor inside; and a transmission base detachably mounted on the main unit. The transmission base houses a transmission assembly and a blade shaft assembly. The drive motor is connected to the transmission assembly, which is further connected to the blade shaft assembly via a blade shaft rotation assembly and a blade shaft lifting assembly. A mixing blade is fixed on the blade shaft assembly. This configuration allows the drive motor to transmit power to the transmission assembly during use, which then transmits power to the blade shaft rotation assembly and the blade shaft lifting assembly. The blade shaft rotation assembly drives the blade shaft assembly to rotate, and the blade shaft lifting assembly drives it to move up and down. This, in turn, causes the blade shaft assembly to rotate and lift the mixing blade. The design is simpler, less expensive, and allows for a smaller overall machine size.

[0007] According to the above scheme, the cutter shaft assembly includes a cutter shaft output shaft and a cutter shaft input shaft. The cutter shaft output shaft can slide vertically on the cutter shaft input shaft, and the cutter shaft output shaft and the cutter shaft input shaft are axially locked together. The cutter shaft rotation assembly is located between the transmission assembly and the cutter shaft input shaft; the cutter shaft lifting assembly is located between the transmission assembly and the cutter shaft output shaft. With this configuration, when the transmission assembly transmits power to the cutter shaft rotation assembly and the cutter shaft lifting assembly, the cutter shaft rotation assembly drives the cutter shaft input shaft to rotate, and the cutter shaft input shaft then drives the cutter shaft output shaft to rotate; simultaneously, the cutter shaft lifting assembly drives the cutter shaft output shaft to move up and down relative to the cutter shaft input shaft.

[0008] According to the above scheme, the tool shaft lifting assembly includes a bearing housing, a reduction gearbox, and a drive shaft. The tool shaft output shaft is rotatably mounted on the bearing housing, and the tool shaft output shaft and the bearing housing are radially interlocked. The input end of the reduction gearbox is connected to the transmission assembly, and the output end of the reduction gearbox is connected to the drive shaft. The drive shaft is drively connected to the bearing housing. When the drive shaft is driven by the reduction gearbox, the drive shaft drives the bearing housing to rise and fall. With this configuration, when the transmission assembly transmits power to the reduction gearbox, the reduction gearbox drives the drive shaft to move, the drive shaft drives the bearing housing to rise and fall, and the bearing housing then drives the tool shaft output shaft to rise and fall.

[0009] According to the above scheme, the bearing housing is provided with a sliding groove, a connecting rod is fixed on the transmission shaft, and a connecting shaft is fixed on the connecting rod. The connecting shaft is slidably connected to the sliding groove, and the axis of the connecting shaft is eccentrically set with the axis of the transmission shaft. With this configuration, the transmission shaft is driven to rotate by a reduction gearbox. When the transmission shaft rotates, it drives the connecting rod to rotate. When the connecting rod rotates, it drives the connecting shaft to rotate along the axis of the transmission shaft. During the rotation of the connecting shaft, it slides and displaces in the sliding groove, which can drive the bearing housing to rise and fall during the sliding process.

[0010] According to the above scheme, a lifting guide assembly is provided between the bearing housing and the transmission housing. The lifting guide assembly includes a sleeve on the bearing housing and a guide post on the transmission housing, and the sleeve and the guide post are slidably connected. This arrangement makes the lifting of the bearing housing stable.

[0011] According to the above scheme, the reduction gearbox includes a reduction gear and a gear ring seat. The reduction gear is rotatably mounted in the gear ring seat. The input end of the reduction gear is connected to the transmission assembly, and the output end of the reduction gear is provided with a central output shaft. The central output shaft and the transmission shaft are connected in a transmission connection. In this configuration, the reduction gear is driven to rotate by the transmission assembly. When the reduction gear rotates, it drives the central output shaft to rotate, and the central output shaft drives the transmission shaft to rotate.

[0012] According to the above scheme, a bevel gear one is fixed on the central output shaft, and a bevel gear two is fixed on the transmission shaft. Bevel gear one and bevel gear two are meshed together. With this configuration, when the central output shaft rotates, it drives bevel gear one to rotate, which in turn drives bevel gear two to rotate, and bevel gear two then drives the transmission shaft to rotate.

[0013] According to the above scheme, the cutter shaft rotation assembly includes a cutter shaft drive gear, which is fixedly connected to the cutter shaft input shaft and is also connected to a transmission assembly. In this configuration, the cutter shaft drive gear is driven to rotate by the transmission assembly, and its rotation causes the cutter shaft input shaft to rotate.

[0014] According to the above scheme, the transmission assembly includes a connector and a transmission gear. The drive motor is driven by the connector, and the connector is driven by the transmission gear. The transmission gear is driven by the cutter shaft rotation assembly and the cutter shaft lifting assembly. With this configuration, when the transmission base is mounted on the main unit, the connector is driven by the drive motor, which drives the connector to rotate. The connector then drives the transmission gear to rotate, and the rotation of the transmission gear drives the cutter shaft transmission gear of the cutter shaft rotation assembly and the reduction gear of the cutter shaft lifting assembly to rotate.

[0015] According to the above scheme, it also includes a cup assembly, which includes a cup cover and a stirring cup. The cup cover is fixed on the transmission seat, and the stirring cup is detachably installed inside the cup cover. The cup cover is provided with an oil seal that is interference-fitted with the output shaft of the cutter shaft.

[0016] Beneficial effects of this invention: In this invention, during assembly and use, the drive motor transmits power to the transmission assembly, which then transmits the power to the cutter shaft rotation assembly and the cutter shaft lifting assembly. The cutter shaft rotation assembly drives the cutter shaft assembly to rotate, and the cutter shaft lifting assembly drives the cutter shaft assembly to move up and down, thereby causing the cutter shaft assembly to drive the stirring blade to rotate and move up and down within the cup assembly. Compared with the existing technology that uses a dual-motor structure or a dual-output-shaft single-motor structure, this invention has a simpler structure, lower cost, and can achieve a smaller overall product size.

[0019] The technical solution of the present invention will be described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1 to 5 As shown, this invention provides an ice cream machine, including a main unit 1, which houses a drive motor 11; and a transmission base 2, detachably mounted on the main unit 1. The transmission base 2 houses a transmission assembly and a blade shaft assembly. The drive motor 11 is connected to the transmission assembly, which is connected to the blade shaft assembly via a blade shaft rotation assembly and a blade shaft lifting assembly. A stirring blade 23 is fixed on the blade shaft assembly. This configuration, using a single-axis drive motor 11 in conjunction with the blade shaft rotation and lifting assemblies to drive the blade shaft assembly to rotate and lift, results in a simpler structure, lower cost, and a smaller overall machine size. Specifically, during assembly and use, the drive motor 11 transmits power to the transmission assembly, which then transmits power to the blade shaft rotation and lifting assemblies. The blade shaft rotation assembly drives the blade shaft assembly to rotate, and the blade shaft lifting assemblies drive the blade shaft assembly to lift, thereby causing the blade shaft assembly to drive the stirring blade 23 to rotate and lift.

[0021] Compared with existing technologies that use a dual-motor structure or a dual-output-shaft single-motor structure, this invention has a simpler structure, lower cost, and can achieve a smaller overall product size.

[0022] The host 1 and the transmission base 2 are provided with a locking assembly, which includes a locking block on the host 1 and a locking groove on the transmission base 2. The locking block and the locking groove are screwed together and fixed, making it easy to install and remove, and taking up little space when stored.

[0023] Furthermore, the cutter shaft assembly includes a cutter shaft output shaft 24 and a cutter shaft input shaft 25. The cutter shaft output shaft 24 is slidably mounted on the cutter shaft input shaft 25, and the cutter shaft output shaft 24 and the cutter shaft input shaft 25 are axially locked together. The cutter shaft rotation assembly is located between the transmission assembly and the cutter shaft input shaft 25. The cutter shaft lifting assembly is located between the transmission assembly and the cutter shaft output shaft 24. With this configuration, when the transmission assembly transmits power to the cutter shaft rotation assembly and the cutter shaft lifting assembly, the cutter shaft rotation assembly drives the cutter shaft input shaft 25 to rotate, and the cutter shaft input shaft 25 then drives the cutter shaft output shaft 24 to rotate. At the same time, the cutter shaft lifting assembly drives the cutter shaft output shaft 24 to move up and down relative to the cutter shaft input shaft 25.

[0024] The cutter shaft output shaft 24 is provided with a polygonal connecting hole, and the cutter shaft input shaft 25 is provided with a polygonal connecting post. The polygonal connecting hole can be slidably fitted onto the polygonal connecting post. After the cutter shaft output shaft 24 and the cutter shaft input shaft 25 are assembled, the cutter shaft output shaft 24 can be raised and lowered relative to the cutter shaft input shaft 25. The cutter shaft output shaft 24 and the cutter shaft input shaft 25 are axially locked together, thereby enabling the cutter shaft input shaft 25 to drive the cutter shaft output shaft 24 to rotate.

[0025] Furthermore, the tool shaft lifting assembly includes a bearing housing 28, a reduction gearbox, and a drive shaft 210. The tool shaft output shaft 24 is rotatably mounted on the bearing housing 28, and the tool shaft output shaft 24 and the bearing housing 28 are radially interlocked. The input end of the reduction gearbox is connected to the transmission assembly, and the output end of the reduction gearbox is connected to the drive shaft 210. The drive shaft 210 is drively connected to the bearing housing 28. When the drive shaft 210 is driven by the reduction gearbox, the drive shaft 210 drives the bearing housing 28 to rise and fall. With this configuration, when the transmission assembly transmits power to the reduction gearbox, the reduction gearbox drives the drive shaft 210 to move, the drive shaft 210 drives the bearing housing 28 to rise and fall, and the bearing housing 28 then drives the tool shaft output shaft 24 to rise and fall.

[0026] The bearing housing 28 includes a bearing housing and a bearing installed in the bearing housing. The cutter shaft output shaft 24 is connected to the bearing. After the cutter shaft output shaft 24 and the bearing housing 28 are assembled, the cutter shaft output shaft 24 can rotate relative to the bearing housing 28. The cutter shaft output shaft 24 and the bearing housing 28 are radially locked together, thereby enabling the bearing housing 28 to drive the cutter shaft output shaft 24 to rise and fall.

[0027] Furthermore, the bearing housing 28 is provided with a sliding groove 281, a connecting rod 211 is fixed on the transmission shaft 210, and a connecting shaft 212 is fixed on the connecting rod 211. The connecting shaft 212 is slidably connected to the sliding groove 281, and the axis of the connecting shaft 212 is eccentrically set with respect to the axis of the transmission shaft 210. With this configuration, the transmission shaft 210 is driven to rotate through a reduction gearbox. When the transmission shaft 210 rotates, it drives the connecting rod 211 to rotate. When the connecting rod 211 rotates, it drives the connecting shaft 212 to rotate along the axis of the transmission shaft 210. During the rotation of the connecting shaft 212, it slides and displaces in the sliding groove 281, and during the sliding process, it can drive the bearing housing 28 to rise and fall.

[0028] It should be noted that, as Figure 4 As shown, when the connecting rod 211 drives the connecting shaft 212 to rotate above the transmission shaft 210, the blade shaft assembly drives the stirring blade 23 to the top position inside the cup assembly; as Figure 5 As shown, when the connecting rod 211 drives the connecting shaft 212 to rotate below the transmission shaft 210, the blade shaft assembly drives the stirring blade 23 to be located at the bottom of the cup assembly, thereby realizing the cyclic cutting of the food in the cup assembly.

[0029] Furthermore, a lifting guide assembly is provided between the bearing housing 28 and the transmission housing 2. The lifting guide assembly includes a sleeve on the bearing housing 28 and a guide post 213 on the transmission housing 2, and the sleeve and the guide post 213 are slidably connected. This arrangement makes the lifting of the bearing housing 28 stable.

[0030] There are two sleeves and guide posts 213.

[0031] Furthermore, the reduction gearbox includes a reduction gear 29 and a gear ring seat 214. The reduction gear 29 is rotatably mounted within the gear ring seat 214. The input end of the reduction gear 29 is connected to a transmission assembly, and the output end of the reduction gear 29 is provided with a central output shaft 217, which is connected to a transmission shaft 210. In this configuration, the reduction gear 29 is driven to rotate by the transmission assembly. When the reduction gear 29 rotates, it drives the central output shaft 217 to rotate, which in turn drives the transmission shaft 210 to rotate.

[0032] The gear ring seat 214 includes an upper cover and a gear ring, and a connecting rod 211 is fixed after one end of the drive shaft 210 passes through the gear ring seat 214.

[0033] Furthermore, a first bevel gear 215 is fixed on the central output shaft 217, and a second bevel gear 216 is fixed on the transmission shaft 210. The first bevel gear 215 and the second bevel gear 216 are meshed together. With this configuration, when the central output shaft 217 rotates, it drives the first bevel gear 215 to rotate, which in turn drives the second bevel gear 216 to rotate, and the second bevel gear 216 then drives the transmission shaft 210 to rotate.

[0034] Furthermore, the cutter shaft rotation assembly includes a cutter shaft drive gear 26, which is fixedly connected to the cutter shaft input shaft 25 and is also connected to a transmission assembly. In this configuration, the cutter shaft drive gear 26 is driven to rotate by the transmission assembly, and its rotation causes the cutter shaft input shaft 25 to rotate.

[0035] Furthermore, the transmission assembly includes a connector 21 and a transmission gear 27. The drive motor 11 is connected to the connector 21, and the connector 21 is connected to the transmission gear 27. The transmission gear 27 is connected to both the cutter shaft rotation assembly and the cutter shaft lifting assembly. This configuration, as shown... Figures 2 to 5 As shown, when the transmission seat 2 is assembled on the host 1, the connector 21 is connected to the drive motor 11. The drive motor 11 can drive the connector 21 to rotate, and the connector 21 then drives the transmission gear 27 to rotate. When the transmission gear 27 rotates, it drives the cutter shaft transmission gear 26 of the cutter shaft rotation assembly to rotate and the reduction gear 29 of the cutter shaft lifting assembly to rotate.

[0036] The transmission base 2 is equipped with a mounting bracket that cooperates with the transmission gear 27, the cutter shaft transmission gear 26 and the reduction gearbox. After assembly, the transmission gear 27 can always maintain meshing and transmission with the cutter shaft transmission gear 26 and the reduction gear 29.

[0037] Furthermore, it also includes a cup assembly, which includes a cup cover 22 and a stirring cup 3. The cup cover 22 is fixed on the transmission base 2, and the stirring cup 3 is detachably installed inside the cup cover 22. The cup cover 22 is provided with an oil seal 221 that is interference-fitted with the cutter shaft output shaft 24.

[0038] The cup cover 22 is fixed to the bottom of the transmission seat 2. The blade output shaft 24 passes through the oil seal 221 and extends into the cup cover 22 to be fixedly connected to the stirring blade 23. The stirring blade 23 is located inside the cup cover 22, making it safer to use.

[0039] After the stirring cup 3 and the cup cover 22 are assembled, the stirring cup 3 is located inside the cup cover 22. The stirring cup 3 is easy to install, remove and clean.
