[0045] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0047] like Figure 1 As shown, the present invention provides a paper laying machine electrostatic support moving system, the paper laying machine electrostatic support moving system comprises:

[0048] A stepper motor, used to drive the electrostatic rod bracket to move, wherein the number of the stepper motors is at least two;

[0049] PLC, used to control the movement of the stepper motor and receive control instructions from the host computer;

[0050] The host computer is used to connect to the PLC via wired or wireless communication and output the control instructions for controlling the stepper motor. The host computer is provided with a touch screen.

[0051] In one embodiment, the electrostatic rod bracket is provided with a front limit proximity switch, a rear limit proximity switch and an origin proximity switch to respectively detect the front limit, rear limit and origin positions of the electrostatic rod bracket and feed back to the PLC for position calibration.

[0052] The touch screen is used to input the moving position and speed parameters of the electrostatic rod, display the position and speed of the electrostatic rod in real time, and perform positioning operations, which include absolute positioning, relative positioning, and return to origin operation modes.

[0053] The stepper motor is connected to the lead screw through a coupling, and the lead screw is connected to the electrostatic rod bracket through a bearing and a slider, so that the rotational motion of the stepper motor is converted into the linear motion of the electrostatic rod bracket.

[0054] The elements of the system include any one or more of a PLC, a stepper driver, a circuit breaker and a switching power supply, and the various elements are electrically connected to achieve overall control and power supply of the system.

[0055] The PLC is connected to the host computer via wired or wireless means.

[0056] The control instructions include initialization instructions, relative positioning instructions, absolute positioning instructions and homing instructions of the motion axis, wherein the homing instruction must be executed before the absolute positioning instruction is executed.

[0057] The control instruction also includes a setting parameter instruction for setting when executing the positioning instruction, and the setting parameter instruction includes any one or more of acceleration time, deceleration time and positioning speed.

[0058] The paper laying machine electrostatic support mobile system adopts a modular design concept as a whole. Each module realizes the high-precision movement of the electrostatic support through reasonable hardware configuration and software control. The stepper motor is the core driving device, and the stepper motor is responsible for the actual movement of the electrostatic rod support. At least two stepper motors are used in the scheme to ensure the stability and high-precision control of the system. PLC (Programmable Logic Controller) is the control core, which is responsible for receiving control instructions from the host computer and converting these instructions into specific operations of the stepper motor, including the start, stop, positioning and other actions of the movement. The host computer serves as a human-computer interaction interface. The host computer uses a touch screen for operators to input parameters and monitor the system operation status. The host computer communicates with the PLC through wired or wireless means and transmits the operator's commands to the PLC.

[0059] like Figure 2 and Figure 3 The figure shows a mechanical device diagram A and B of a paper laying machine electrostatic support moving system. The two side brackets 5 of the electrostatic rod use two stepping motors 1 to drive the coupling 2, bearing 3, and lead screw 4 to make a rotational motion, which is converted into a linear motion of the electrostatic rod bracket 5, the electrostatic support platform 6, the slider 7, and the electrostatic rod 11. The front limit 8 is the origin proximity switch, the origin 9 is the front limit 8 proximity switch, and the rear limit 10 is the rear limit proximity switch. Figure 4 The following is a list of electrical components for the electrostatic support moving system of the paper laying machine. Figure 5 The figure shows the electrical layout of the electrostatic support moving system of the paper laying machine, which includes circuit breakers, switching power supplies, PLC programmable controllers, and stepper drivers. Figure 6 The figure shows the power distribution principle diagram of the electrostatic support moving system of the paper laying machine. Figure 7The control principle circuit diagram of the electrostatic support moving system of the paper laying machine is shown in the figure. Here, the PLC's Q0.0 high-speed pulse output point and Q0.2 are used as the direction control point. The PLC's one high-speed pulse output point and one direction output point are creatively used to control at least two stepper drivers at the same time, thereby realizing the synchronous operation of at least two stepper motors, and achieving the synchronous movement of the electrostatic support when moving. Figure 8 The following is a program symbol diagram of the electrostatic support moving system of the paper laying machine, which provides a symbol table in the PLC program for easy use during programming. Fig. 9 The figure shows the schematic diagram of the initialization instructions of the motion axis of the electrostatic support moving system of the paper laying machine. The program design includes the initialization instructions of the motion axis. Fig.10 The figure shows the relative positioning instructions of the electrostatic support moving system of the paper laying machine. The program design includes relative positioning instructions. Fig.11 The figure shows the absolute positioning instructions of the electrostatic support moving system of the paper laying machine. When performing absolute positioning, the origin must be returned first. Fig.12 The figure shows the schematic diagram of the homing instruction of the electrostatic support moving system of the paper laying machine. After the origin is approached by the switch, this position is set as the origin, i.e. the zero point, in order to help the stepper motor find the origin. Fig.13 The figure shows the schematic diagram of setting parameter instructions for the electrostatic support moving system of the paper laying machine, executing instructions for acceleration time, deceleration time and positioning speed. Fig.14 The figure shows a schematic diagram of the touch screen interface of the electrostatic support mobile system of the paper laying machine. The upper computer uses a touch screen as the operation interface and is connected to the PLC through Ethernet to control the movement of the electrostatic rod. The required moving position of the electrostatic rod is set according to the on-site process requirements. Free positioning consists of relative positioning, absolute positioning, and return to the origin. The operator can move the electrostatic rod over a short distance and display the real-time position and speed at the same time. When the electrostatic rod moves to the front limit or rear limit, it stops moving and is displayed on the screen. The parameter setting is used to set the acceleration time, deceleration time and positioning speed when executing the positioning command.

[0060] The stepper motor controls its rotational motion through the PLC, and finally converts the rotational motion into the linear movement of the electrostatic rod bracket through mechanical devices such as couplings and screws, thereby ensuring that the conversion process from electrical signals to physical motion is controllable and accurate. Position detection and calibration are achieved by setting the front limit, rear limit and origin proximity switches on the electrostatic rod bracket to detect the position of the bracket and provide real-time feedback to the PLC. The PLC calibrates the position of the bracket through these signals to ensure that the bracket does not exceed the set movement range during the movement. The touch screen is not only used to input the moving position and speed parameters of the electrostatic rod, but also to realize absolute positioning, relative positioning and return to origin operation modes, providing operators with flexible control means to ensure that the bracket can move accurately according to the predetermined trajectory. The PLC is connected to the host computer by wire or wireless means to ensure that the system can maintain reliable communication in different environments. The control instructions include motion axis initialization, positioning and return to origin instructions to ensure that the correct initialization operation can be performed before absolute positioning is performed to avoid system errors caused by misoperation. The control instructions also include instructions for setting parameters, such as acceleration time, deceleration time and positioning speed. These parameters optimize the response speed and accuracy of the system, making the movement of the electrostatic rod bracket more stable and efficient. The host computer is responsible for input and monitoring, the PLC is responsible for control and execution, the stepper motor is responsible for actual physical movement, and the limit switch provides feedback to ensure that the entire system operates in a safe and efficient state. Through the cooperation of PLC, stepper motor, host computer and various sensors, the automatic and high-precision movement of the electrostatic bracket has been successfully realized.

[0061] In the technical solution of this embodiment, the PLC controls two stepper drivers at the same time through a high-speed pulse output signal to ensure the synchronous operation of the two stepper motors, especially the electrostatic bracket achieves high-precision movement at a higher speed, thereby ultimately achieving the flatness of the paper laying machine.

[0062] like Fig.15 As shown, the present invention provides a method for moving an electrostatic support of a paper laying machine, and the method for moving an electrostatic support of a paper laying machine comprises:

[0063] In step S11, the PLC receives a control instruction from a host computer in a binding relationship;

[0064] In step S12, the PLC controls at least two stepping drivers simultaneously through a high-speed pulse output signal;

[0065] In step S13, the at least two stepping drivers drive the electrostatic rod support to perform linear motion along the lead screw.

[0066] In one embodiment, a PLC (programmable controller) is used to control two stepper motors to drive the electrostatic bracket to move, and the touch screen in the host computer is used to move and position according to the set distance and speed. The PLC receives control instructions from the host computer. The "host computer" here usually refers to a device with advanced processing capabilities, such as a computer or a specific control panel, which is responsible for issuing control instructions. There is a specific connection or communication protocol between the PLC and the host computer to ensure the accurate reception and execution of instructions. The PLC controls the stepper driver through a high-speed pulse output signal. The PLC can send a pulse signal through the output channel to control the speed and direction of the stepper motor. The high-speed pulse indicates that the pulse frequency output by the PLC is high, which is related to the high response speed and precise control capability of the stepper motor. At least two stepper drivers receive high-speed pulse signals from the PLC and drive the stepper motor according to these signals. The stepper driver is a power amplifier and controller of the stepper motor, which converts the pulse signal of the PLC into the rotational motion of the motor. After receiving the control signal through the stepper driver, the stepper motor drives the electrostatic rod bracket to move linearly along the lead screw. The lead screw is a mechanical component that converts rotational motion into linear motion. It is connected to the output shaft of the stepper motor and pushes the electrostatic rod bracket to move along its axis through a threaded mechanism.

[0067] The binding relationship between the host computer and the PLC ensures the accurate transmission of control instructions, which is achieved through wired or wireless communication, requiring a reliable data exchange mechanism between the host computer and the PLC. As the brain of the control system, the PLC is responsible for parsing the instructions of the host computer and converting them into specific control signals, which are sent through the output channel of the PLC to control the stepper driver with high-speed pulses. The stepper driver receives the pulse signal of the PLC, accurately controls the speed and direction of the stepper motor, realizes the linear motion control of the electrostatic rod bracket, and allows the system to achieve precise position control and speed control. The above technical solution is realized through the reception, processing and execution of instructions, as well as the close cooperation between mechanical movement and electrical control.

[0068] The host computer, PLC, stepper driver and stepper motor work together to achieve precise control of the electrostatic rod bracket.

[0070] The receiving module 21 is used for the PLC to receive control instructions from a host computer in a binding relationship;

[0071] The control module 22 is used for the PLC to simultaneously control at least two stepping drivers through a high-speed pulse output signal;

[0072] The driving module 23 is used for the at least two stepping drivers to drive the electrostatic rod support to perform linear motion along the lead screw.
