[0002] When the applicant conducted market research, it was found that in some enterprises with large printing volume, when the bound paper is treated as waste, in order to reduce waste, the staple on the bound paper needs to be removed for reusing the back of the paper for printing or copying. When the staple is removed, the bound paper will have a binding hole, and the multiple bound papers will be attached together through the binding hole. When the back of the paper is reused for printing or copying, the multiple bound papers attached together through the binding hole will enter the printer or copier together.

[0037] The other side of the first circular ring 4 in the left-right direction has a first box body 18, in which paper is placed obliquely, and the paper is always subjected to a pushing force in the direction of the first circular ring 4;

[0038] When one of the suction cups 12 rotates to the position of the first box body 18 during the rotation of the first circular ring 4, the suction cup 12 is in communication with the fan-shaped groove 6, and the paper is adsorbed on the suction cup 12; when the suction cup 12 rotates to the position of the first flat plate 10, the suction cup 12 is disconnected from the fan-shaped groove 6, and the adsorbed paper falls onto the first flat plate 10; when the suction cups at staggered positions in the plurality of suction cups rotate to above the first circular ring 4, the angle of the suction cup is rotated by 180°.

[0043] The circular pipe 11 can move in and out of the first circular ring 4, a tension spring is sleeved outside the hose 8, one end of the tension spring is fixed on the circular pipe 11, and the other end of the tension spring is fixed on the second circular ring 3; a stop block 15 is fixed on the circular pipe 11 placed outside the first circular ring 4;

[0044] A horizontal circular rod 17 is fixed on the rear end surface of the shell 1 and is placed in the front-rear direction, the first wedge block 16 is fixed on the circular pipe 11 placed outside the first circular ring 4; when the first circular ring 4 drives the circular pipe 11 to rotate the suction cup 12 to the position where the outer end surface of the suction cup 12 is parallel to the paper in the first box body 18, the circular rod 17 extrudes the first wedge block 16 to make the circular pipe 11 drive the suction cup 12 to move outward and be attached to the paper, and the paper is adsorbed on the suction cup 12; after the adsorption is completed, the tension spring resets the circular pipe 11 and the suction cup 12.

[0045] The front end surface of the second circular ring 3 and the first circular ring 4 is fixed with a disc 22, and the front end surface of the disc 22 is fixed with a rotating rod 31.

[0046] The number of the circular tubes 11 is four, and each of the circular tubes 11 is sleeved with a rectangular block 9, and the circular tube 11 is inserted into the rectangular block 9 and can rotate in the rectangular block 9, and the two ends of the circular tube 11 penetrate through the inner and outer end surfaces of the rectangular block 9, and the outer end of the circular tube 11 extends out of the rectangular block 9.

[0048] Two non-adjacent circular tubes 11 among the four circular tubes 11 are fixed with friction wheels 13, and an arc-shaped block 14 is fixed on the rear side surface of the cavity of the shell 1, when the circular tube 11 rotates to the arc-shaped block 14, the friction wheel 13 contacts with the arc-shaped block 14, so that the circular tube 11 rotates by 180°.

[0049] The suction disc 12 is a hollow funnel-shaped structure made of soft rubber, the end with larger diameter faces outward, and the end surface of the end with larger diameter is in an inner circular arc structure in transverse section;

[0050] When the suction disc 12 is attached to the paper, because the outer end surface of the suction disc is in an inner circular arc structure, the inner circular arc structure can make the paper bend and deform, so that the paper attached together through the binding holes can be better separated;

[0051] A gas leakage hole is arranged on the end surface of the inner side of the suction disc;

[0052] When the suction disc sucks the paper, the gas leakage hole does not affect the adsorption, when the circular tube 11 is not communicated with the fan-shaped groove 6, the gas leakage hole makes the air pressure on the inner side of the suction disc equal to the air pressure on the outer side of the suction disc, so as to ensure the separation of the paper and the suction disc.

[0053] The first box body 18 is a rectangular shell with an open upper end, a straight rod 19 is inserted and arranged on the right side plate of the first box body 18, the straight rod 19 can move left and right on the right side plate of the first box body 18, a spring is sleeved on the straight rod 19 arranged outside the first box body 18, one end of the spring is fixed on the first box body 18, and the other end of the spring is fixed on the right end of the straight rod 19; a second flat plate 20 is fixed on the end portion of the straight rod 19 arranged in the cavity of the first box body 18, the second flat plate 20 is arranged in an inclined manner with the left end being lower than the right end, and a first rotating wheel 21 is arranged on the left end of the cavity of the first box body 18.

[0054] The right side of the first flat plate 10 is fixed with a baffle 23 at the front and rear ends, and the inner side of the lower end of each baffle 23 is fixed with a second wedge 24; the lower right end of the first flat plate 10 is provided with a second box body 27, the upper end of the second box body 27 is open, and a left-high right-low inclined plate 28 is fixed in the cavity; the right end of the first flat plate 10 and the second box body 27 are provided with a second rotating wheel 25 and a third rotating wheel 26, and the two rotating wheels are in close contact with each other.

[0055] The front end of the rotating rod 31 of the present application protrudes out of the shell 1 and is fixed with a first pulley 29, the front end of the rotating shaft of the second rotating wheel 25 and the third rotating wheel 26 protrudes out of the shell 1, the rotating shaft of the second rotating wheel 25 protruding out of the shell 1 is fixed with a second pulley 30, the second pulley 30 is connected with the first pulley 29 through a belt, and the rotating shafts of the second rotating wheel 25 and the third rotating wheel 26 protruding out of the shell 1 are fixed with meshing gears.

[0056] Since the first box body 18 is arranged on the right side and the first flat plate 10 is arranged on the left side, the rotating rod 31 is counterclockwise during use to drive the second circular ring 3 and the first circular ring 4 to rotate, and the second rotating wheel 25 and the third rotating wheel 26 are driven to rotate towards each other through the belt and the gear; the fan-shaped groove 6 is communicated with the air pump through the blind hole, so that a negative pressure state is formed in the fan-shaped groove 6, and the rotating rod 31 can be driven by the motor.

[0057] The right side plate of the shell 1 is openable, before use, the paper to be bound is placed on the second flat plate 20 in the first box body 18, and the bound paper is pretreated first, the pretreatment content is that after the staple is removed, the multiple papers will still be attached together under the action of the binding hole, for the sake of convenience, the multiple papers still attached together after the staple is removed are called a paper, before being placed in the first box body 18, the positions of the binding holes on the multiple papers are placed in unison, since each paper is multiple, the amount of work at this time is not large, after the paper is placed on the second flat plate 20, the paper is moved to the right to stretch the spring, the spring simultaneously gives the paper a left extrusion force, and finally the left side of the paper is in contact with the first rotating wheel 21.

[0058] After the paper is placed on the second flat plate 20 in the first box 18, the motor is started to drive the rotating rod 31 to rotate counterclockwise, and the air pump makes the fan-shaped groove 6 in a negative pressure state. When the suction cup 12 rotates to the outer end surface of the suction cup 12 being parallel to the paper in the first box 18, the circular pipe 11 is communicated with the fan-shaped groove 6 through the hose 8 and the air hole 7, and the circular rod 17 extrudes the first wedge block 16 to make the circular pipe 11 drive the suction cup 12 to move outward and adhere to the paper. Under the action of the negative pressure, the suction cup 12 adsorbs the paper on the outer end surface thereof. When the suction cup 12 adheres to the paper, the outer end surface of the suction cup is in an inner arc shape, which causes the paper to be bent and deformed, so that the paper adhered through the binding hole is better separated.

[0059] After the adsorption is completed, the circular pipe 11 and the suction cup 12 are reset by the tension spring, and the suction cup 12 continues to rotate with the first circular ring 4. Assuming that the suction cup 12 does not have the friction wheel 13, when it rotates above the first circular ring 4, it will not rotate by 180°, and then continue to rotate. When it rotates to the position of the first flat plate 10, the circular pipe 11 is disconnected with the fan-shaped groove 6, the negative pressure state in the suction cup 12 disappears, the paper falls off from the suction cup 12 and falls onto the first flat plate 10. Under the guidance of the baffle 23 and the second wedge block 24 on the first flat plate 10, the direction of the paper is adjusted and the paper slides down along the first flat plate 10. Then the paper enters the second box 27 after being pressed by the second rotating wheel 25 and the third rotating wheel 26.

[0060] The suction cup 12 behind the suction cup 12 is fixed with the friction wheel 13, and the latter suction cup 12 repeats the action of the former suction cup, that is, it adsorbs the paper at the position of the first box 18. When the latter suction cup 12 rotates above the first circular ring 4, the friction wheel 13 on the latter suction cup 12 will contact with the arc-shaped plate 14, and the arc-shaped plate 14 makes the friction wheel 13 rotate 180° on the rectangular block 9 with the circular pipe 11, that is, the suction cup 12 and the paper adsorbed thereby rotate horizontally by 180°, so that the positions of the binding holes on the two papers previously adhered are staggered. After the paper rotates by 180°, the latter suction cup 12 continues to rotate, and at the position of the first flat plate 10, the suction cup no longer provides suction, and the air vent makes the air pressure inside the suction cup equal to that outside the suction cup, so that the rotated paper falls onto the first flat plate 10, and then enters the second box 27 after being pressed by the second rotating wheel 25 and the third rotating wheel 26, and is re-stacked with the former paper. However, the positions of the binding holes on the two papers have been staggered, and the two papers will not be adhered together due to the binding holes after being re-stacked.

[0061] The present application utilizes multiple suction cups to suck the bound suction cup, and because the suction cups at staggered positions in the multiple suction cups have friction wheels 13, the suction cup 12 and the paper thereon can be rotated, so that the paper at the interval position in the paper that is pasted together with consistent binding hole positions can be rotated, the binding hole positions of the previously pasted together paper are staggered, and at the same time, the binding holes are flattened by the rolling of the second rotating wheel 25 and the third rotating wheel 26, completely solving the problem of the paper pasting together caused by the binding holes.
