Abstract
The invention discloses a drum-type vacuum paper-absorbing device, which is characterized in that the device consists of a vacuum air-absorbing region, a large drum and an air-blowing region. The working method comprises the following steps: a paper is sent to the paper-sending opening of the large drum in a way that a paper-sending wheel drives a paper-sending belt; the vacuum air-absorbing region which is positioned at the paper-sending opening of the large drum absorbs the paper through pinholes on the surface of the large drum, and a paper-pressing wheel presses the paper; the paper which is steadily absorbed is detected by the linear trace of a camera in the process of absorbing; and the absorbed paper continuously turns into the air-blowing region at the paper-sending opening of the large drum with the large drum, the paper is separated from the surface of the large drum, finally the paper which is pressed by a paper-guiding wheel successfully enters into a paper-receiving belt which is driven by a paper-receiving wheel through a paper-baffling plate to complete the work. The invention has the advantages that a gripper is not used in the process of transmitting the paper, a vacuuming drum is used for absorbing and steadily sending the paper, the paper is steady in the process of scanning and detecting without any paper skip abnormal phenomena such as jumping, shaking and the like, the steadily absorbed paper leads various detections at the position to be more accurate, and the device has simple and compact structure, and saves space.

The exit slot of above-mentioned said swift has the splicing wheel; Said splicing wheel connects the splicing band; Said splicing band picks out the exit slot of paper by swift.
The surface of sending out between paper mouth and exit slot of above-mentioned said swift is connected with paper guiding roll and pressure roller, and the top is provided with to detect uses camera.
The paper mouth of sending out of above-mentioned said swift is provided with pressing board.
A kind of method of work of drum-type vacuum paper-absorbing device is characterized in that it may further comprise the steps:
(1) paper drives the paper mouth that a paper tape is sent to paper swift by sending out the paper wheel;
(2) be positioned at the vacuum suction district that swift is sent out paper mouth place, the aperture by the swift surface adsorbs paper, and by pressure roller paper is pushed down;
(3) adsorb stably paper and finish testing through camera linear scan in absorption phase;
(4) Xi Fu paper turns to the air blowing district that swift is sent out paper mouth place continuously with swift, and paper breaks away from the swift surface, and paper guiding roll is pressing paper to enter smoothly on the splicing band that is driven by the splicing wheel through pressing board, finishes the work.
Operation principle of the present invention: utilize vacuum that paper is adsorbed on the swift circumference, do not hold paper in the month and do not re-use tooth row, paper steadily can be done detection in adsorption process, drying the paper swift that blows off for making it break away from smoothly swift utilization in the detection back that finishes, makes paper enter next section transport portion smoothly.
Superiority of the present invention is: (1) the present invention does not use tooth row in defeated paper process, and utilizing has the cylinder of inhaling vacuum that paper is held and steadily defeated paper, and paper is steady when scanning detects, and it is unusual not have paper feeds such as beating and rocks; (2) adsorbing stably, paper makes that various detections herein are more accurate; (3) saving simple and compact for structure space; (4) owing to there is not tooth row to hold paper in the month, speed improves and has improved production efficiency simultaneously.
