(4) Resetting the X-axis movement mechanism 122 and the Y-axis movement mechanism 123, adjusting the focal length of the lens of the positioning device 1212, and setting relevant parameters such as exposure parameters, so that the edge of the writing paper 10 in the acquired image is clearly visible.
(5) Setting a font of the content to be written on the control terminal 200, thereby providing data for cutting the writing paper 10; at the same time, the operation causes the guillotine 1213 to move down to the cutting position, observing whether the blade is attached to the cutting zone table.
The second step is that: the reel mechanism 130 rolls once, thereby completing one transfer of the current writing area.
And cutting off the adsorption power supply, releasing the adsorption of the adsorption electrode on the spring festival scroll writing paper 10, simultaneously, driving the reel mechanism 130 to transmit the writing paper 10 once, receiving the data of the selective encoder from the discharge reel 134 by the control terminal 200 to perform accurate rolling of the transmission distance, and performing the third step after transmitting the blank writing paper 10 to the writing area.
The third step: and electrifying the electrode adsorption array to adsorb and fix the writing paper 10.
And starting an adsorption electrode high voltage generation circuit to generate positive and negative 3000V high voltage, and then, carrying out automatic working state on the system.

The fourth step: the writing paper 10 is automatically detected for inclination and the table 110 is adjusted according to the situation.
The control terminal 200 automatically retrieves the image of the positioning device 1212, performs pre-filtering, edge detection and line detection algorithms on the image, detects the edge line of the writing paper 10, and calculates an included angle β of the edge line with respect to the Y-axis of the field of view of the positioning device 1212 (i.e., the X-axis of the device frame of the present invention). As shown in FIG. 7, if | β ≦ 0.5 °, the writing paper 10 is considered to be free from deflection; otherwise, the turntable motor is started to perform the reverse angle adjustment until the edge line of the writing paper 10 is nearly parallel to the Y axis of the viewing field of the positioning device 1212 and the included angle requirement is met, and the next step can be performed.
The fifth step: the X-axis movement mechanism 122 and the Y-axis movement mechanism 123, and the writing pen movement mechanism 120 are driven to move, completing the writing simulation operation.
The control terminal 200 calls information of the Chinese characters to be written in real time, and the Chinese characters are written on the plane of the writing paper 10 through the mutual matching of the XY axis and the Z axis movement mechanism, the Z axis movement represents writing force information to a certain extent, and the required Chinese characters are written one by one under the automatic control of the control terminal 200 until the completion.
Meanwhile, the system will automatically pre-determine whether the writing paper 10 delivered from the discharging reel 134 is complete, if not, continue to operate in the second step, otherwise, enter the sixth step.
And a sixth step: the cutter movement mechanism 1214 is driven to move, and the cutting of the writing paper 10 is completed.
The system first resets the paper cutter 1213, drives the paper cutter movement mechanism 1214, takes the writing paper 10 in the fourth step at the inclination angle β, rotates the paper cutter 1213 head by means of the data, drives the Z-axis movement mechanism to move the cutter head downward, and drives the Y-axis movement mechanism to perform one-time cutting.
The seventh step: unloading, reloading and returning.
And (3) judging whether the writing of the whole roll of writing paper 10 is finished or not in advance, if so, automatically cutting off the power supply of the electrostatic adsorption electrode after all Chinese characters are written, resetting the equipment, and taking down the writing paper 10 on the feeding paper guide roller 132, the writing table top and the discharging paper guide roller 133. Meanwhile, if the writing is required to be continued, the material is reloaded and returns to the first step to be executed.
