[0028] Please refer to Figure 1, the paper sheet feeding mechanism 20, the roll paper feeding mechanism 30 and the conveying mechanism 40 are arranged at different sides of the paper gathering platform 10, the paper sheet feeding mechanism 20 is used for stacking the paper sheets, the paper suction assembly 22 is used for sucking the single paper sheet, the paper gathering assembly 41 can convey the paper sheet sucked by the paper suction assembly 22 to the paper gathering platform 10, and the conveying assembly 42 is used for conveying the paper sheet to the discharge end.

[0031] It can be explained that when the suction nozzle is close to the surface of the flat paper stacked on the paper stacking platform 21, the suction cylinder generates suction force through the extension and retraction action, so that the suction nozzle can firmly adsorb the flat paper. Subsequently, the paper feeding cylinder is started, and the suction nozzle carrying the adsorbed flat paper is moved to the direction of the paper collecting assembly 41. During the movement, the suction nozzle maintains the adsorption state of the flat paper, ensuring stable paper conveying. When the suction nozzle reaches the designated position of the paper collecting assembly 41, the paper collecting assembly 41 acts immediately to smoothly transfer the flat paper adsorbed by the suction nozzle to the paper collecting platform 10.

[0032] The paper feeding cylinder ensures that the suction nozzle carrying the paper moves smoothly and accurately to the working area of the paper collecting assembly 41, reduces the probability of paper deviation, paper jam and other faults occurring during the transmission process, and improves the reliability of flat paper conveying.

The fourth conveying wheel 414 is located between the third conveying wheel 413 and the fifth conveying wheel 415. The third conveying wheel 413 and the fifth conveying wheel 415 have the same rotation direction and are opposite to the rotation direction of the fourth conveying wheel 414. The third conveying wheel 413 and the fourth conveying wheel 414 rotate oppositely to cooperate to convey the flat paper conveyed by the first paper collecting wheel set to the paper collecting platform 10. The fourth conveying wheel 414 and the fifth conveying wheel 415 rotate oppositely to cooperate to convey the flat paper cut by the cutting member 33 to the paper collecting platform 10.

[0034] Please refer to Figure 2The first paper collecting wheel set is arranged above the second paper collecting wheel set, the first paper collecting wheel set is used to deliver the flat paper adsorbed by the paper suction assembly 22 to the second paper collecting wheel set, and the second paper collecting wheel set is used to deliver the flat paper delivered by the first paper collecting wheel set and the flat paper after being cut to the paper collecting platform 10. Specifically, when the paper feeding cylinder moves the suction nozzle adsorbed with the flat paper to the vicinity of the first paper collecting wheel set, the flat paper extends between the first conveying wheel 411 and the second conveying wheel 412, and the first conveying wheel 411 and the second conveying wheel 412 are clamped on both sides of the flat paper, at this time, the paper feeding cylinder drives the suction nozzle to release the flat paper, and the first conveying wheel 411 and the second conveying wheel 412 rotate relatively to deliver the flat paper to between the third conveying wheel 413 and the fourth conveying wheel 414 of the second paper collecting wheel set.

The cutting member 33 is delivered to between the fifth conveying wheel 415 and the fourth conveying wheel 414 by the paper feeding assembly 31, and the flat paper after being cut by the cutting member 33 is delivered to the paper collecting platform 10 by the relative rotation of the fifth conveying wheel 415 and the fourth conveying wheel 414. Through the cooperation of the first paper collecting wheel set and the second paper collecting wheel set, the efficiency and stability of the flat paper delivery are effectively improved, so that the flat paper from the flat paper feeding mechanism 20 and the flat paper from the roll paper feeding mechanism 30 can be smoothly converged on the paper collecting platform 10.

[0035] In an embodiment, a paper pushing plate 416 is arranged between the fourth conveying wheel 414 and the fifth conveying wheel 415, the paper pushing plate 416 is arranged at an angle with the conveying direction of the flat paper, and the paper pushing plate 416 is used to push the flat paper between the fourth conveying wheel 414 and the fifth conveying wheel 415 to flatten the flat paper.

[0036] It should be noted that the fourth conveying wheel 414 and the fifth conveying wheel 415 cooperate to deliver the flat paper delivered by the paper feeding assembly 31 to the paper collecting platform 10, and the direction from the paper feeding assembly 31 to the paper collecting platform 10 is the conveying direction of the flat paper. After the roll paper is cut into flat paper by the cutting member 33, the flat paper is prone to rebound, the extension direction of the paper pushing plate 416 is arranged at an angle with the conveying direction of the flat paper, and when the flat paper passes between the fourth conveying wheel 414 and the fifth conveying wheel 415, the paper pushing plate 416 can gently scrape the surface of the flat paper to eliminate the curling problem caused by the rebound of the flat paper. By reasonably setting the inclination angle of the paper pushing plate 416, the paper pushing plate 416 can neither hinder the normal conveying of the flat paper nor ensure the flattening effect, so that the flat paper after being cut reaches the paper collecting platform 10 in a flat state.

After the paper stacking platform 21 is driven to descend by the lifting drive, the flat papers stacked on the paper stacking platform 21 can be obtained. Through the intelligent linkage of the capacitive proximity switch, the lifting drive and the suction cylinder, the automatic ascending and descending of the paper stacking platform 21 and the accurate adsorption of the flat papers are realized, and the intelligent level is high. When the flat papers stacked on the paper stacking platform 21 are of different heights, the operation of feeding the flat papers one by one can be ensured, and the versatility is strong. It should be noted that the capacitive proximity switch, the lifting drive, the suction cylinder and the controller all adopt the prior art.

After the stacking of the flat papers is completed, the plurality of limiting pieces are caused to abut against different sides of the flat papers stacked in different sides respectively by rotating the adjusting hand wheel, so as to ensure the neat stacking of the flat papers, to provide an accurate adsorption position for the suction assembly 22, and to effectively improve the stability of the flat papers in the feeding process.

[0041] In an embodiment, the paper feeding assembly 31 comprises a sixth conveying wheel 311 and a seventh conveying wheel 312 which approach each other, and the sixth conveying wheel 311 and the seventh conveying wheel 312 rotate relative to each other to pull the roll paper to move towards the paper collecting platform 10.
