[0028] Please also see Figures 1 to 10 , the present invention provides a preferred embodiment of an ice cream machine control circuit.

[0029] In some embodiments, Figure 1 and Fig.10As shown, the present invention provides an ice cream machine control circuit, which is used in an ice cream machine, and includes: a microcontroller unit 100, a switching power supply module 200, a sampling module 300, a lifting control module 400, a lifting motor for driving the tool lifting, a first rotation control module 500, a first rotation drive motor for driving the tool to rotate, a second rotation control module 600 and a second rotation drive motor for driving the extrusion molding mechanism 40 to work; the first rotation control module 500 is connected to the first rotation drive motor and the microcontroller unit 100 respectively, and is used to control the speed of the first rotation drive motor according to the first speed control signal output by the microcontroller unit 100; the second rotation control module 600 is connected to the second rotation drive motor and the microcontroller unit 100, and is used to control the speed of the second rotation drive motor according to the second speed control signal output by the microcontroller unit 100; the sampling module 300 is connected to the first rotation drive motor and the second rotation drive motor respectively, and is used to collect the first input current and the first driving power of the first rotation drive motor and the second input current and the second driving power of the second rotation drive motor; the lifting control module 400 is connected to the lifting control module 50 ... The lifting motor is connected to the microcontroller unit 100, and is used to control the speed of the lifting motor according to the third speed control signal output by the microcontroller unit 100; wherein the speed of the first rotation drive motor, the speed of the second rotation drive motor and the speed of the lifting motor correspond to various types of ice cream; the microcontroller unit 100 is respectively connected to the lifting control module 400, the first rotation control module 500, the second rotation control module 600 and the sampling module 300, and is used to adjust the first speed control signal according to the first input current and the first driving power to adjust the first rotation The speed of the driving motor and the third speed control signal are adjusted to adjust the speed of the lifting motor, and are used to adjust the second speed control signal according to the second input current and the second driving power to adjust the speed of the second rotation drive motor; the switching power supply module 200 is respectively connected to the microcontroller unit 100, the sampling module 300, the lifting control module 400, the first rotation control module 500, and the second rotation control module 600, and is used to power the microcontroller unit 100, the sampling module 300, the lifting control module 400, the first rotation control module 500, and the second rotation control module 600.

[0030] Specifically, please combine Figure 2 and Figure 3The ice cream machine includes a main body 10, a cup barrel 20, a cutter 30, a cutter lifting mechanism, a cutter rotating mechanism, an extrusion molding mechanism 40, etc. The first rotary drive motor is used to drive the cutter 30 rotating mechanism to move, so that the cutter 30 can rotate, the lifting motor is used to drive the cutter 30 lifting mechanism to move, so that the cutter 30 can move up and down, and the second rotary drive motor can drive the extrusion molding mechanism 40 to move, so that the ice cream in the extrusion molding mechanism 40 can be extruded from the extrusion molding mechanism 40 according to the set shape.

[0031] For different types of ice cream, the descending speed and descending rotation speed of the cutter 30 are different. For example, the descending power (the greater the power, the faster the rotation speed) of the milk shake ice cream is controlled at 257W, and the descending rotation speed is controlled at 1800rpm, and the descending power of the low-fat ice cream is controlled at 245W, and the descending rotation speed is controlled at 1795rpm, so that the time to complete different types of ice cream is also different, so that ice cream with different softness and hardness can be obtained. Correspondingly, in the process of forming ice cream, for different types of ice cream, the rotation speed requirements of the second rotation control motor are also different.

[0032] Different types of ice cream correspond to different working modes. In different working modes, the control parameters of the first rotary drive motor and the lifting motor are different. Therefore, in the corresponding working modes, the rotation speeds of the first rotary drive motor, the second rotary drive motor and the lifting motor are different for different types of ice cream. It should be noted that the rotation speeds of the first rotary drive motor, the second rotary drive motor and the lifting motor are related to their input current and driving power. By detecting the input current and driving power of the first rotary drive motor, the second rotary drive motor and the lifting motor, the rotation speeds of the first rotary drive motor, the second rotary drive motor and the lifting motor in different modes can be adjusted.

[0033] In specific implementation, after selecting the corresponding working mode of ice cream, the micro control unit 100 obtains the control parameters of the corresponding ice cream type, outputs a first speed control signal to control the operation of the first rotating drive motor according to the control parameters, and outputs a third speed control signal to control the operation of the lifting motor. In the process of preparing ice cream, the input current and driving power of the first rotating drive motor are collected by the sampling module 300. When it is detected that the input current or driving power exceeds a preset threshold, the micro control unit 100 can adjust the speed of the first rotating drive motor and the speed of the lifting motor to reduce the descending speed and the rotating speed of the cutter 30, so as to further produce ice cream materials of different hardness (the hardness of ice cream materials prepared at different temperatures is different), thereby further improving the taste of ice cream.

[0034] After the preparation of ice cream is completed, the cup barrel 20 containing ice cream is installed on the extrusion molding mechanism 40, and then the micro control unit 100 controls the second rotation control module 600 to drive the second rotation drive motor to work, so that the ice cream can obtain the required shape in the extrusion molding mechanism 40. By sampling the input current and driving power of the second rotation drive motor, the speed of the second rotation drive motor can be adjusted according to the input current and driving power of the second rotation drive motor. In the process of extrusion molding of ice cream, the sampling module 300 will sample the input current and driving power of the second rotation drive motor. When the micro control unit 100 detects that the input current or driving power of the second rotation motor exceeds the preset threshold, the speed of the second rotation drive motor will be adjusted, and ice cream of different softness and hardness can be molded to improve the taste of the molded ice cream.

[0035] It can be seen that the present invention controls different types of ice cream by using different modes, that is, different types of ice cream can be made by controlling the lifting speed and rotating speed of the cutter 30, so that the softness and hardness of the obtained ice cream can be adapted to its material, thereby improving the taste of the ice cream. In addition, in the process of preparing ice cream, by monitoring the input current and driving power of the rotating motor to adjust the rotation speed of the rotating motor and the lifting motor, ice cream materials with different hardness can be made, thereby further improving the taste of the ice cream, and in the process of molding ice cream, by monitoring the input current and driving power of the rotating motor to adjust the rotation speed of the rotating motor, ice cream with different hardness can be molded, thereby improving the taste of the molded ice cream.

The switching signal of the first relay RY1 uses a pulse signal to prevent the first relay RY1 from being in an open state due to continuous signal output when a fault occurs in the micro control unit 100, thereby improving safety in use.

At the same time, the speed of the first rotary drive motor can be fed back to adjust the speed to the working mode corresponding to the ice cream, so that the softness and hardness of the prepared ice cream are better.
