Description

Technical Field

[0001] This utility model relates to the field of food appliance technology, and in particular to a drive module and an ice cream machine. Background Technology

[0002] Ice cream machines are commonly used to make ice cream, smoothies, and other similar products, and can also be used to crush certain ingredients. These machines typically consist of a main body and a cup. To use, the cup is placed in the machine's working area, and the machine uses blades to crush the contents. The cup is then removed from the machine. During the crushing process, the blades rotate and move up and down. A drive module is installed on the main body, which drives the blades to rotate and move up and down.

[0003] The blade is typically located inside the cup lid. During cup assembly and disassembly, the lid is attached to the cup and is removed along with it. The output end of the drive module has a connector. During operation, the connector moves down to insert with the blade, and the blade then rotates and moves up and down synchronously with the connector. In some ice cream machine designs, the drive module drives the connector to rotate and move up and down simultaneously, causing the connector to rotate as it moves down towards the blade for insertion. This means the connector is always rotating during the connection process, resulting in low reliability and a higher risk of transmission failure. Furthermore, the rotating connector experiences significant friction and collision with the blade, leading to considerable vibration and noise. Utility Model Content

[0027] This utility model discloses an ice cream machine, which includes a drive module and a controller.

[0028] Among them, reference Figure 1-6 The drive module includes a bracket assembly 10, a first mounting base 20, a first drive assembly 30, a second mounting base 40, a transmission rod 50, a second drive assembly 60, and a detection assembly. The first mounting base 20 is rotatably mounted on the bracket assembly 10; the first drive assembly 30 is driveably connected to the first mounting base 20 and is used to drive the first mounting base 20 to rotate; the second mounting base 40 is slidably mounted on the bracket assembly 10; the second drive assembly 60 is drively connected to the second mounting base 40 and is used to drive the second mounting base 40 to slide; one end of the transmission rod 50 is rotatably connected to the second mounting base 40, and the other end of the transmission rod 50 slides through the first mounting base 20, with a connector 51 connected to the other end of the transmission rod 50; the detection assembly includes a first detection element 71, a second detection element 72, and a third detection element 73, arranged from top to bottom, and is used to detect the position of the second mounting base 40.

[0029] The first detection element 71, the second detection element 72, and the third detection element 73 can all be contact switches, which are simple, reliable, and easy to assemble and use. In other embodiments, these first detection elements 71, second detection elements 72, and third detection elements 73 can be infrared sensors, proximity switches, or other structures. The sidewalls and top of the second mounting base 40 are provided with trigger protrusions 41, which correspond to the respective detection elements so that each detection element can detect the position of the second mounting base 40.

[0030] During operation, the second mounting base 40 is initially at the top of its travel, triggering the first detection element 71. The ice cream machine's controller then controls the second drive assembly 60 to operate, causing the second mounting base 40 and transmission rod 50 to move downwards. When the second mounting base 40 moves downwards and passes the second detection element 72, triggering it, the connector 51 moves downwards to the position where it mates with the blade. After receiving the signal from the second detection element 72, the controller controls the first drive assembly 30 to operate, driving the first mounting base 20 and transmission rod 50 to rotate. This, in turn, drives the blade through the connector 51. When the head rotates, the second mounting base 40 moves down to the bottom of its stroke, triggering the third detection element 73. After receiving the signal from the third detection element 73, the controller controls the second drive assembly 60 to run in reverse, driving the second mounting base 40 and the transmission rod 50 to move upward. When the second mounting base 40 moves upward and passes the second detection element 72, triggering it, the controller receives the signal from the second detection element 72 and controls the first drive assembly 30 to stop running to prevent the transmission rod 50 from spinning idly. When the second mounting base 40 continues to move upward to the top of its stroke, the first detection element 71 is triggered again, and the next working cycle begins.

[0031] As described above, the second detection element 72 can detect the position of the second mounting base 40 after the connector 51 is inserted and connected to the cutter head. This facilitates the controller's accurate control of the first drive assembly 30, prevents the connector 51 from connecting to the cutter head while rotating, improves the reliability of the connector 51's connection to the cutter head, and reduces the possibility of transmission failures during the connection process. Furthermore, since the connector 51 does not rotate during the connection process, it avoids significant friction and collision with the cutter head, reducing operational vibration and noise.

[0032] In this embodiment, the bracket assembly 10 includes a plate 11, a first base shell 12, and a second base shell 13. The first base shell 12 is disposed on the top of the plate 11 and fixed thereto by screws. The first base shell 12 and the plate 11 form a first mounting cavity for accommodating the first mounting seat 20. The second base shell 13 is disposed on the top of the first base shell 12 and fixed thereto by screws. The second drive assembly 60, the first detection element 71, the second detection element 72, and the third detection element 73 are connected to the second base shell 13.

[0033] In this embodiment, the first mounting base 20 includes a first transmission wheel 21, a retaining plate 22, and a bushing 23. The first transmission wheel 21 is disposed in the first mounting cavity. Two retaining plates 22 are respectively inserted into the upper and lower sides of the first transmission wheel 21. The bushing 23 passes through the first transmission wheel 21 and the retaining plates 22. The other end of the transmission rod 50 passes through the bushing 23 and the plate 11. The side wall of the transmission rod 50 has a first plane, the inner side of the bushing 23 has a second plane that is in contact with the first plane, the outer side of the bushing 23 has a third plane, and the inner side of the retaining plate 22 has a fourth plane that is in contact with the third plane. Bearings are fitted at both the upper and lower ends of the bushing 23. The two bearings are respectively inserted into the plate 11 and the first base shell 12 to rotatably mount the first transmission wheel 21 in the first mounting cavity. Through the cooperation between the planes, the transmission rod 50 can slide up and down relative to the first transmission wheel 21, and the rotation of the first transmission wheel 21 can drive the transmission rod 50 to rotate.

[0034] In this embodiment, a limiting frame 14 is provided on the plate 11. The first drive assembly 30 includes a first motor 31, a second transmission wheel 32, and a transmission belt 33. The first motor 31 is disposed on the plate 11, and the shaft of the first motor 31 is rotatably inserted into the limiting frame 14. The second transmission wheel 32 is located inside the limiting frame 14 and is fixedly sleeved on the shaft of the first motor 31. The transmission belt 33 is wound around the first transmission wheel 21 and the second transmission wheel 32. The transmission belt 33 can be configured as a toothed belt to provide more stable transmission and prevent slippage.

[0035] The above structure enables the first drive assembly 30 to be connected to the first mounting base 20 via transmission; the limiting frame 14 makes the rotation of the second drive wheel 32 more stable; the limiting frame 14 and the first mounting cavity prevent the drive belt 33 from completely detaching from the first drive wheel 21 and the second drive wheel 32 due to jumping.

[0036] In this embodiment, a plurality of guide rods 15 are longitudinally arranged on the inner side of the second housing 13. The two ends of the guide rods 15 are respectively connected to the first housing 12 and the second housing 13. The second mounting base 40 is located inside the second housing 13 and is slidably sleeved on the guide rods 15. This structure allows the second mounting base 40 to slide stably.

[0037] In this embodiment, the second drive assembly 60 includes a reduction gearbox 61, a second motor 62, and a screw 63. The reduction gearbox 61 is mounted on the second housing 13, and the second motor 62 is mounted on the reduction gearbox 61 and is drively connected to the input end of the reduction gearbox 61. The screw 63 is located inside the second housing 13 and is fitted through the second mounting base 40. The lower end of the screw 63 is rotatably connected to the first housing 12, and the upper end of the screw 63 is drively connected to the output end of the reduction gearbox 61. When the second motor 62 is running, it can drive the second mounting base 40 to slide up and down through the cooperation of the screw 63 and the second mounting base 40.

[0038] In the above structure, both the first motor 31 and the second motor 62 are fixed in position and will not move with the connector 51, which can effectively reduce the vibration and noise of the ice cream machine during operation and improve the user experience. In addition, the structure of the second drive assembly 60 is relatively compact, and the transmission chain between the second motor 62 and the screw 63 is short, which can effectively reduce the space occupied by the drive module and facilitate its placement inside the ice cream machine.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
