Two sides be fixedly connected with the corresponding slide plate 28 of groove 35, and slide plate 28 is slidably connected with 35 inner wall of groove, stretches described in two
The extending port stretching that contracting plate 6 is equipped with from connection 34 two sides of shell respectively is slidably socketed in 8 outside of slide bar, placement paper, and due to
The paper of different weight can be maintained at identical height by the elastic force of compressed spring 14, and the paper height for being unlikely to lighter is very low.
The moving member 9 includes double thread bar 15 and swing handle 16, and 1 bottom of workbench passes through two movable plates 5
Center at be equipped with mobile mouth 17, and the both ends of mobile mouth 17 are equipped with the fixed block 18 being fixedly connected with workbench 1, described double
Threaded rod 15 is rotatablely connected by bearing and two fixed blocks 18, and double thread bar 15 stretches out one end and the turning handle of fixed block 18
Hand 16 is fixedly connected, and 5 bottom of movable plate both passes through the mobile rotation of mouth 17 and is socketed in 15 outside of double thread bar, adjusts two 5
Distance between movable plate can place the paper of different model.
Specific embodiment: when the equipment begins to use, printing paper being placed on expansion plate 6, due to connecting shell
34 bottoms are equipped with compressed spring 14, and expansion plate 6 and slide bar 8 are slidably socketed, so expansion plate 6 can be with the weight of paper
Measure different move up and down, it is possible to which the height for guaranteeing that paper is placed will not be too low, and then external force rotates swing handle 16, turns
The rotatory force of dynamic handle 16 drives double thread bar 15 to rotate, since double thread bar 15 has bidirectional force, so two movable plates 5 to
Mobile close to the side of other side, since supporting block 13 is fixedly connected with movable plate 5, and slide plate 28 and groove 35 are to be slidably connected
, so expansion plate 6 can change size as movable plate 5 is mobile, realize the paper for placing different model, then 10 end of air inlet
Air inlet pipe is connected, the other end of air inlet pipe connects micro-blower, and wind is passed to air inlet 10 from air inlet pipe, air-dispersing of then entering bar
7, due to being provided with air dispelling hole 12 on air-dispersing bar 7, so wind passes through air dispelling hole 12 from venthole 11, completion dispels paper.
The mobile adsorbent equipment 4 include driving motor 19, supporting shell 20, screw rod 21, sliding block 22, electric pushrod 23, into
Gas bar 24 and suction nozzle 25, described 21 one end of screw rod and 20 inner wall of supporting shell are rotatablely connected, and 21 other end of screw rod runs through supporting shell
20 and the top of workbench 1 be fixedly connected with 19 output end of driving motor, the driving motor 19 passes through placement plate and workbench 1 one
Side is fixedly connected, and is fixedly connected at the top of 20 both ends of supporting shell and workbench 1, and the rotation of sliding block 22 is socketed in outside screw rod 21
Side, and sliding block 22 is slidably socketed in 20 outside of supporting shell, the electric pushrod 23 is fixedly connected with sliding block 22, and electric pushrod 23

Bar 24 is connect with air inlet pipe one end, and the air inlet pipe other end is controlled to a vacuum pump by solenoid valve, upper layer paper can be picked up,
Into next step process.
Specific embodiment: while paper is dispelled, driving motor 19 rotation drive screw rod 21 rotate, at this time due to
The rotatory force of screw rod 21, the mobile electric pushrod 23 for driving connection fixed thereto of sliding block 22 is mobile, so air intake lever 24 and suction nozzle
25 move in the horizontal direction, and until surface stop motion of the suction nozzle 25 at paper center, air intake lever 24 is connected to air inlet at this time
Pipe, the air inlet pipe other end are connected with vacuum pump, the gas in vacuum pump are transmitted to suction nozzle 25 by air inlet pipe, then electric pushrod 23
Movement drives suction nozzle 25 to move in the vertical direction, and until the paper of first layer is sucked suction nozzle 25, then electric pushrod 23 is transported
It is dynamic that suction nozzle 25 and paper is driven to move upwards, until paper is higher than movable plate 5, then 23 stop motion of electric pushrod, then again
Driving motor 19 is opened, suction nozzle 25 is moved with paper to close to 3 direction of transmission belt, the suction nozzle when paper is contacted with transmission belt 3
25 are placed on paper in transmission belt 3, and paper is moved with transmission belt 3, when paper passes through 27 bottom of letterweight wheel, are further pressed
Flat, paper is transported to next technique therewith.
Positioning port 30 there are two being set on the workbench 1, and positioning port 30 is located at mobile 17 two sides of mouth, the positioning
30 inner wall both ends of mouth are fixedly connected with locating rod 31, and the movable plate 5 is slidably socketed sub- 31 outside of locating rod, moves movable plate 5
Balance is kept when dynamic.
Locating slot 26 is equipped at the top of the expansion plate 6, inside the connection shell 34 equipped with locating slot 26 to corresponding limit
Position block 29 prevents expansion plate 6 from skidded off inside connection shell 34 when connecting and sliding in shell 34.
The compressed spring 14 is equipped with multiple, and multiple compressed springs 14 are evenly distributed is fixedly connected with 6 plate of expansion plate, make
The paper of different weight is maintained at identical height, prevents suction nozzle 25 because the too low suction of paper is inconvenient.
