The specific implementation process is as follows:

the questionnaire is put into the paper guide box 21, and under the gravity of the questionnaire, the questionnaire at the bottom enters the lower part of the feed roller 22 and is pushed forward by the feed roller 22 to the gap between the first paper guide roller 31 and the second paper guide roller 32, so that the questionnaire is pulled downward by the first paper guide roller 31 and the second paper guide roller 32.

The first paper guide roller 31 and the second paper guide roller 32 rotate and simultaneously drive the first crank and the second crank to rotate, the first crank and the second crank rotate to drive the piston 62 to slide in the first cylinder body 61 and the second cylinder body in a reciprocating mode, the first cylinder body 61 and the second cylinder body are matched with the corresponding piston 62 to form an inflator structure, accordingly, the first cylinder body 61 and the second cylinder body continuously supply air to the air box 70, the pressure in the air box 70 is increased, and then the air is sprayed out from the first spray head or the second spray head. Meanwhile, the airflow will enter the pressing cylinder 51, and since the air inlet 54 of the pressing cylinder 51 is much larger than the air outlet, the pressure in the pressing cylinder 51 increases and pushes the piston rod 52 to extend out, and the pressing plate 53 will also move upwards, so that the distance between the pressing plate 53 and the second guide plate 42 increases, and the pressing plate 53 is prevented from blocking the questionnaire from falling on the second pressing plate.

When the back surface of the questionnaire faces the ink probe 23, the first head bends the questionnaire toward the second paper guide roller 32, so that the questionnaire is pushed toward the second guide plate 42 side by the second paper guide roller 32; and the airflow discharged from the discharge holes of the pressing cylinder 51 acts on the questionnaire, so that the questionnaire rapidly sinks down to the second guide plate 42 with the back of the questionnaire facing upward.

When the front of the questionnaire faces the ink probe 23, the two-position three-way reversing solenoid valve 73 reverses, so that the second nozzle ejects air flow; therefore, the questionnaire is bent toward the first guide roller 31, and the questionnaire is pushed toward the first guide plate 41 by the first guide roller 31 and falls on the first guide plate 41, so that the questionnaire slides along the first guide plate 41 toward the second guide plate 42 with the back surface of the questionnaire facing upward, thereby finishing the arrangement of the questionnaire.

After the input of the questionnaire is completed, the driving motor is stopped, and the stop valve 72 is closed; the air pressure in the pressing cylinder 51 is gradually discharged from the exhaust port, so that the piston rod 52 slides down by the tension spring, and finally the pressing plate 53 is pressed against the questionnaire.

The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
