DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1: In view of the technical problem that the prior art cannot complete intelligent monitoring and corresponding regulation when disordered sheets or paper jams occur during paper conveying, and timely correct or even shut down the paper conveying equipment for normal use, the following technical solution is proposed:

[0036] Reference Figure 1 - Fig.10 As shown, in this embodiment, a paper processing and conveying device with an electrically flexible paper guide wheel mechanism is provided, comprising a pair of stacked lower upright plates 1 and upper upright plates 2, wherein two groups of lower upright plates 1 and upper upright plates 2 are provided and are spaced apart, and support assemblies are provided at the proximal ends of the lower upright plates 1 and upper upright plates 2, and guide assemblies are installed on the lower upright plates 1 and upper upright plates 2 through the support assemblies, and the guide assemblies include a movable wheel group 9 movably arranged between the support assemblies, and a limiting ring 24 is installed on the inner end of the movable wheel group 9, and movable cavities 14 are provided at the portions of the lower upright plates 1 and upper upright plates 2 corresponding to the limiting ring 24, and the movable cavities 14 on both sides are respectively a positive bias cavity 14a and a negative bias cavity 14b, and a pair of movable wheel groups 9 are horizontally displaced in the positive bias cavity 14a and the negative bias cavity 14b respectively through the limiting ring 24;

[0037] An outer top plate 21 is embedded in the lower half of the middle part of the outer side of the movable wheel group 9, and a stabilizing plate 20 is installed on the outer side of each movable wheel group 9 corresponding to the lower vertical plate 1. A pressure plate 22 in contact with the outer top plate 21 is installed on the upper end of the stabilizing plate 20. Both the outer top plate 21 and the pressure plate 22 are latex structures and are embedded with pressure sensors.

[0038] Reference Figure 2 and Figure 7 As shown, a driving rod 8 connected to the driving motor is inserted in the middle of the movable wheel group 9, and an active rotating rod 4 is installed between a pair of driving rods 8. A driven rotating rod 5 rotatably connected to the inner side of the upper vertical plate 2 is suspended above the active rotating rod 4. A plurality of driving gears 26 distributed at intervals are sleeved on the outside of the active rotating rod 4. A driven gear 27 meshing with the driving gear 26 is sleeved on the outside of the driven rotating rod 5, and a plurality of photoelectric sensors are embedded in the tooth gap of the driving gear 26.

[0039] Reference Figure 2 - Figure 6 As shown, the lower vertical plate 1 and the upper vertical plate 2 are relatively provided with an inner support seat 17, a middle support seat 18 and an outer support seat 19, and the lower vertical plate 1 and the upper vertical plate 2 form an adjustment cavity 11 through the gap between the two groups of inner support seats 17, middle support seats 18 and outer support seats 19. A guide plate 16 whose inner end is connected to the inner support seat 17 is horizontally movably installed between the lower vertical plate 1 and the upper vertical plate 2, and the guide plate 16 is horizontally displaced in the adjustment cavity 11. The guide plate 16 is in a "U" shape and a driving wheel 7 is threadedly sleeved on the outer end. Several driving wheels 7 are driven to rotate by the driving structure respectively. The lower vertical plate 1 and the upper vertical plate 2 are embedded with a rail rod 10 corresponding to the outer side of the adjustment cavity 11, and a guide rail frame 15 sleeved with the guide plate 16 is installed on the outer end of the rail rod 10. A spiral groove 23 is provided on the inner ring side of the driving wheel 7, and a threaded portion meshing with the spiral groove 23 is provided on the outer side of the guide plate 16 extending to the front end of the guide wheel group 9;

[0040] Anti-dropout rods 13 plugged with the upper vertical plate 2 are installed at both ends of the driven rotating rod 5. The end of the anti-dropout rod 13 close to the driven rotating rod 5 is rotatably connected with the active rotating rod 4 through a sleeve seat. The anti-dropout rod 13 is bent and the outer height is higher than the inner height. When the active rotating rod 4 rotates, the driven rotating rod 5 and the anti-dropout rod 13 are not driven to complete the rotation under the rotation connection of the sleeve seat. When the active rotating rod 4 deviates from the horizontal position, the anti-dropout rod 13 plugged with the upper vertical plate 2 is used to achieve guided movement.

[0041] Structural principle: The present application provides a structure capable of laterally adjusting the horizontal position of the movable wheel set 9, wherein the driving motor cooperates with the rotation of the driving wheel 7 to complete the speed adjustment and the horizontal displacement adjustment, specifically as follows: when the horizontal position of the movable wheel set 9 needs to be changed, the driving motor meshing with the driving wheel 7 is started, and the driving motor drives the driving wheel 7 to rotate, and the driving wheel 7 drives the guide plate 16 to move through the spiral groove 23, and the guide plate 16 drives the inner support seat 17 to move, and the movement of the inner support seat 17 drives the movable wheel set 9 to move outward, at this time, the movable wheel set 9 is displaced outward horizontally, and the position change of the movable wheel set 9 causes the active rotating rod 4 to be displaced, and further drives the driven rotating rod 5 suspended on the active rotating rod 4 to be displaced synchronously, and finally realizes the position deflection of the paper on the driven rotating rod 5, and combines the deflection direction during the paper feeding process to implement the corresponding correction action;

[0042] It should be supplemented that: during the movement of the movable wheel set 9, the limit ring 24 is also driven to horizontally displace in the positive bias cavity 14a and the negative bias cavity 14b respectively, and the photoelectric sensors arranged in the positive bias cavity 14a and the negative bias cavity 14b obtain the displacement of the limit ring 24 in real time, which can also reflect the current deviation distance. At the same time, the limit ring 24 can also achieve the purpose of offset limiting in the positive bias cavity 14a and the negative bias cavity 14b.

[0043] The pressure sensor is externally connected to a control system, the control system includes an offset detection module, an offset calibration module, an offset correction execution control module and a drive management unit that are communicatively connected, wherein the control system is also communicatively connected to a photoelectric sensor;

[0044] The deviation detection module is used to acquire the deviation information by collecting the position information through the photoelectric sensor during the paper conveying process, and send the deviation information to the deviation calibration module. The deviation calibration module performs data analysis on the deviation information. The analysis process is as follows: the photoelectric sensor scans the edge side of the paper being fed, and collects the running track of the edge side and converts it into a track graph with the feeding direction as the x-axis and the direction of the active rotating rod 4 as the y-axis. Then, each track point is extended to the x-axis to form a vertical line segment together with the x-axis to form a triangular area. The triangular area is compared with the preset standard triangular area. If the triangular area exceeds the range of the standard triangular area, a deviation over-limit signal is generated. Otherwise, if the triangular area does not exceed the standard triangular area, a deviation adjustable signal is generated.

[0045] The deviation correction execution control module can control the rotation arc length of the driving wheel 7 and the speed of the driving motor, obtain pressure information during operation and perform analysis and processing, and the analysis and processing process is as follows: when the outer top plate 21 embedded in the movable wheel group 9 is deformed by the squeezing action of the pressure-bearing plate 22, and the embedded pressure sensor receives the pressure signal and sends it to the deviation correction execution control module, the deviation correction execution control module compares and analyzes the obtained pressure information with the pressure information threshold preset by the system, and generates an over-pressure signal if the pressure information is greater than the pressure information threshold, and generates an under-pressure signal if the pressure information is less than or equal to the pressure information threshold, and sends the over-pressure signal and the under-pressure signal to the pressure difference calibration module;

[0046] The pressure difference calibration module performs combined comparative analysis on the received pressure over-limit signal and pressure under-limit signal, respectively, with the deviation over-limit signal and the deviation adjustable signal. The combined comparative analysis process is as follows:

[0047] When the pressure over-limit signal and the deviation over-limit signal are received, a stop signal is directly generated, at which time the equipment is stopped, and the paper is removed and re-fed;

[0048] When a pressure over-limit signal and a deviation adjustable signal or a pressure under-limit signal and a deviation adjustable signal are received, a deviation correction monitoring signal is generated and sent to the drive management unit to adjust the rotation arc length of the drive wheel 7;

[0049] When the pressure shortage signal and the deviation over-limit signal are received, a deviation correction monitoring signal is generated and sent to the drive management unit to jointly adjust the rotation speed of the drive motor and the rotation arc length of the drive wheel 7;

[0050] Basic principle: During the paper conveying process, the horizontal position change of the active rotating rod 4 is first realized through the adjustable active wheel set 9, so that the speed adjustment and horizontal displacement adjustment are completed during the real-time feeding process. When the paper in the feeding process deflects, the corresponding correction action is implemented in combination with the deflection direction to ensure that the paper is accurately conveyed and the printing process is completed accurately; in addition, the paper conveying intelligent control system is used to collect the displacement deviation and offset pressure difference information during the paper conveying process to determine whether the current paper conveying equipment is in a normal conveying state, so as to quickly make guiding actions for the correction and shutdown of the entire paper conveying equipment, meet the deviation correction needs of the paper conveying equipment in the process of conveying printed paper, and improve the level of intelligent working condition monitoring;

[0051] Embodiment 2: This embodiment is based on Embodiment 1, and an additional lossless paper conveying component is provided to prevent segmental indentations and the like generated during paper conveying;

[0052] Reference Figure 7 and Fig.10As shown, it includes: a driving rod 8 connected to a driving motor is inserted in the middle of a movable wheel group 9, an active rotating rod 4 is installed between a pair of driving rods 8, a driven rotating rod 5 rotatably connected to the inner side of an upper vertical plate 2 is suspended above the active rotating rod 4, a plurality of driving gears 26 distributed at intervals are sleeved on the outside of the active rotating rod 4, a driven gear 27 meshing with the driving gear 26 is connected to the outer surface of the driven rotating rod 5, a pair of paper pressing wheels 25 are symmetrically installed in the middle of the outer side of the driven rotating rod 5, a paper feeding belt 12 is connected to the outer surface of the paper pressing wheel 25, and spiral paper feeding rings 6 wound around the outer side of the driven rotating rod 5 are installed at both ends of the paper pressing wheel 25, and the outer ring surfaces of the paper feeding belt 12 and the spiral paper feeding ring 6 are flush;

[0053] Structural advantages: When the paper to be printed is transported, it is directly pushed to the spiral paper feeding ring 6 by the conveying device in sequence, and the driving motor drives the active rotating rod 4 to rotate through the driving rod 8. The active gear 26 on the outside of the active rotating rod 4 engages with the driven gear 27 to drive the driven rotating rod 5 to complete the reverse rotation, and then the paper feeding belt 12 outside the driven rotating rod 5 and the spiral paper feeding ring 6 drive the paper to complete the feeding;

[0054] It is important to note that during the feeding process, firstly, there is no pressure-bearing object on the upper surface of the paper; secondly, the paper is fed and transported by the paper feeding structure in which the paper feeding belt 12 and the spiral paper feeding ring 6 are in non-full-time contact at the same position. Therefore, no segmental indentation will be produced under the weight of the paper. Under the premise of no offset pushing, the paper can ensure to complete the center feeding without disorderly sheets or paper jams.

[0055] In summary: In combination with Example 1 and Example 2, on the one hand, no pressure-bearing object is set on the upper surface of the feeding paper; on the other hand, the paper is fed and conveyed by the paper feeding structure of the paper feeding belt 12 and the spiral paper feeding ring 6 in non-full-time contact at the same position, so that no segmental indentation will be generated under the weight of the paper, and under the premise of no offset pushing, the paper can ensure the completion of center feeding, and no disorderly sheets or paper jams will occur; the horizontal position change of the active rotating rod 4 is realized by the adjustable active wheel group 9, so that the speed adjustment and the horizontal displacement adjustment are completed in the real-time feeding process, so that when the position of the paper in the feeding process is deflected, the corresponding correction action is implemented in combination with the deflection direction, so as to ensure that the paper is accurately transported and the accurate printing process is completed; in addition, an intelligent paper transportation control system is used to collect the displacement deviation and the offset pressure difference information during the paper transportation process to determine whether the current paper transportation equipment is in a normal transportation state, so as to quickly make guiding actions for the correction and shutdown of the entire paper transportation equipment, meet the deviation correction needs of the paper transportation equipment in the process of transporting printed paper, and improve the level of intelligent working condition monitoring.
