In addition, the design of the slip ring 706 makes the slave communication line and the DC bus not entangled or knotted during rotation, further improving the reliability and service life of the equipment.

[0050] The user interaction device 800 can include a bottle blowing interaction module 801 and a filling interaction module 802, both of which are electrically connected to the controller 701. The bottle blowing interaction module 801 is used for mutual transmission of bottle blowing action interaction information with the controller 701, and the filling interaction module 802 is used for mutual transmission of filling action interaction information with the controller 701.

[0051] In addition, the user interaction device 800 further comprises an Internet of Things module 803 electrically connected with the controller 701, for transmitting Internet of Things communication information with the controller 701.

At the same time, the Internet of Things module 803 can also support remote maintenance and fault warning of the equipment, reducing the maintenance cost and downtime of the equipment.

[0052] In some embodiments, the user interaction device 800 is used to send a running parameter to the controller 701, and the controller 701 is used to send a control instruction to the frequency converter according to the running parameter. The frequency converter is used to set the frequency of itself to a preset frequency according to the control instruction and the rated frequency, and is also used to set the rotating speed of the variable frequency motor 601 to a corresponding preset rotating speed according to the control instruction and the rated rotating speed of the variable frequency motor 601.

[0053] Specifically, taking the variable frequency motor 601 connected to the lifting machine in the embryo forming device 100 as an example, the variable frequency motor 601 is controlled by the corresponding variable frequency driver 702, and the rated rotating speed of the variable frequency motor 601 is 1450 rpm, and the rated frequency of the corresponding variable frequency driver 702 is 50 hz. The user can set a power percentage parameter in the user interaction device 800, for example, set the percentage parameter to 30%, then the running frequency of the variable frequency driver 702 is set to 30%*50 hz=15 hz, and the output rotating speed of the variable frequency motor 601 is 30%*1450 rpm=435 rpm.

[0054] In some embodiments, the driving device 600 further comprises a main shaft encoder 603 electrically connected with the blowing main shaft motor 601a and the controller 701, for obtaining a real-time rotating angle of the blowing main shaft motor 601a and transmitting the real-time rotating angle to the controller 701; the controller 701 is used to generate a virtual difference angle according to the number of blowing assemblies 330, and generate an actual deflection angle of each blowing assembly 330 according to the virtual difference angle and the real-time rotating angle, and is also used to send a blowing action instruction to the driving device connected with the corresponding blowing action motor 602a according to the actual deflection angle of each blowing assembly 330, and the servo driver 703 is used to control the corresponding blowing action motor 602a to perform the corresponding blowing action according to the blowing action instruction.

[0055] Specifically, the spindle encoder 603 can be directly connected to the blow molding spindle motor 601a to measure the real-time rotation angle of the spindle of the blow molding spindle motor 601a, thereby obtaining the rotation angle of the blow molding spindle 320 at any given time. The spindle encoder 603 can be connected to a servo driver 703, and through the servo driver 703, it can be connected to the controller 701, transmitting the measured real-time rotation angle to the controller 701.

[0056] For example, combining Figure 3 As shown, the blowing spindle 320 rotates 360° in one revolution. There are 20 blowing assemblies 330. The virtual difference angle is 360° / 20 = 18°. Starting from any one of the blowing assemblies 330, they are numbered sequentially according to the rotation direction of the blowing spindle 320 (counterclockwise in the diagram) as the first blowing assembly 330, the second blowing assembly 330, ..., the twentieth blowing assembly 330. If the real-time rotation angle of the blowing spindle motor 601a read by the spindle encoder 603 is A, then the actual deflection angle of the first blowing assembly 330 is A, the second blowing assembly 330 is A, and so on. The actual deflection angle B of component 330 is B = A - 18°, and the actual deflection angle C of the twentieth blow molding component 330 is A + 18°. This allows the position of any blow molding component 330 at any given time to be obtained. Then, based on the action requirements of the blow molding component 330 at different positions, the controller 701 sends precise blow molding action commands to the corresponding driver. After receiving the blow molding action commands, the driver drives the corresponding blow molding action motor 602a to run, so that the blow molding component 330 can perform corresponding blow molding actions, such as opening or closing the blow molding mold, blowing air and moving the blow molding rod, etc.

The bottled product production equipment according to claim 6, characterized in that, The user interaction device is used to send operating parameters to the controller, and the controller is used to send control commands to the driver according to the operating parameters; The driver is used to set its own frequency to a preset frequency according to the control command and the rated frequency, and is also used to set the speed of the drive motor to a corresponding preset speed according to the control command and the rated speed of the drive motor.

8. The bottled product production equipment according to claim 6, characterized in that, The user interaction device includes a blow molding interaction module and a filling interaction module. Both the blow molding interaction module and the filling interaction module are electrically connected to the controller. The blow molding interaction module is used to transmit blow molding action interaction information to and from the controller, and the filling interaction module is used to transmit filling action interaction information to and from the controller.

9. The bottled product production equipment according to claim 6, characterized in that, The user interaction device also includes an Internet of Things (IoT) module, which is electrically connected to the controller and is used to transmit IoT communication information with the controller.

10. The bottled product production equipment according to any one of claims 1-5, characterized in that, The blow molding device includes a frame, a blow molding wheel rotatably connected to the frame, and multiple blow molding assemblies movably connected to the blow molding wheel and arranged around the circumference of the blow molding wheel. The multiple drive motors include a blow molding spindle motor and multiple blow molding action motors; the blow molding spindle motor is connected to the blow molding wheel and is used to drive the blow molding wheel to rotate; the blow molding action motor is connected to the corresponding blow molding assembly and is used to drive the blow molding assembly to perform blow molding action; the drive device also includes a spindle encoder, which is electrically connected to the blow molding spindle motor and the controller, and is used to acquire the real-time rotation angle of the blow molding spindle motor and transmit the real-time rotation angle to the controller; The controller is used to generate a virtual difference angle based on the number of blown bottle components, and to generate the actual deflection angle of each blown bottle component based on the virtual difference angle and the real-time rotation angle. It is also used to send a blow-blowing action command to the corresponding driver according to the actual deflection angle of each blow-blowing assembly. The driver is used to control the operation of the corresponding blow-blowing action motor according to the blow-blowing action command, so as to drive the corresponding blow-blowing assembly to perform the corresponding blow-blowing action.
