Detailed Description

The following describes details and operational principles of embodiments and examples of the present invention with reference to the drawings. The paper overlapping mechanism comprises a slow conveying part 11 and a high-speed conveying part 12, wherein the slow conveying part comprises a front conveying belt 1, the high-speed conveying part 12 adopts a paper feeding roller or a conveying belt, the conveying speed of the high-speed conveying part is higher than that of the slow conveying part, a tail paper sucking part 13 is arranged between the input end of the slow conveying part 11 or the high-speed conveying part and the slow conveying part, and the tail paper sucking part comprises an intermittent paper sucking suction hole 7. If the tail paper suction component 13 is arranged at the input end of the slow conveying component 11, there are two situations, wherein in the first situation, the front conveying belt 1 is provided with air holes, the tail conveying component is arranged in the front conveying belt, and the air holes are communicated with the air suction holes 7; secondly, the front conveying belts 1 are provided with a plurality of groups, and the tail paper suction parts 13 are arranged between the adjacent front conveying belts 1; when the paper 2 gets into the preceding conveyer belt, the suction hole 7 breathes in, and the afterbody of paper 2 is adsorbed, arranges in on the preceding conveyer belt 1, and then the suction hole stops breathing in, avoids causing the influence to the transport of paper, also avoids causing the influence to the overlapping of next paper, and paper 2 is carried forward by preceding conveyer belt 1, just can not hit preceding paper when next paper gets into preceding conveyer belt, but the afterbody of overlapping at preceding paper. If the tail paper sucking component 13 is arranged between the slow conveying component and the high conveying component, when the front end of the paper 2 enters the front conveying belt 1, the air suction holes 7 suck air, the tail of the paper is sucked downwards, the air suction holes 7 stop sucking air, when the next paper enters the low conveying component 11 from the high conveying component 12, the previous paper completely enters the front conveying belt 1, and at the moment, the head of the next paper is just overlapped on the tail of the previous paper. Present paper gets into low-speed conveyor part by high-speed conveyor part and can be scotched by conveyer belt or pinch roller at the in-process paper of deceleration, and the utility model discloses a paper afterbody is inhaled to the afterbody and part 13 holds the paper afterbody through suction, makes the paper successfully slow down, can avoid the paper impaired at the deceleration in-process like this, consequently the afterbody is inhaled paper part 13 and is not only made a back paper and a preceding paper realization and stably overlap, and the afterbody is inhaled the paper part and can also be played the deceleration effect moreover, avoids the paper impaired at the deceleration in-process, improves the paper quality of cutting machine.

The tail paper suction component also comprises an air suction air chamber 9, the air suction air chamber is connected with an exhaust fan 14, the air suction holes 7 are formed in the air suction air chamber 9, the paper 2 has a certain width, so that the adsorption stability is ensured, the air suction holes 7 can be arranged in a plurality of numbers, the number of the air suction holes can be set according to requirements, baffles 4 matched with the air suction holes are arranged in the air suction air chamber 9, the number of the baffles is consistent with the number of the air suction holes 7, the air suction holes are not sucked when the baffles 4 block the air suction holes, and when the air suction holes are communicated with the air suction air chamber, the air suction holes 7 suck air, so that intermittent air suction is realized; baffle 4 can adopt the over-and-under type, and the baffle shifts up and blocks the suction hole then the suction hole does not breathe in, when the baffle moves down, the suction hole then breathes in, in this embodiment, baffle 4 rotates power part with its drive and is connected, and power part can adopt motor 10, through-hole 8 has been seted up on the baffle, when baffle 4 rotates to through-hole 8 and suction hole 7 relative time, suction hole 7 communicates with each other with convulsions air chamber 9, and when through-hole and suction hole on baffle 4 stagger, suction hole 7 is sheltered from by the baffle, and the suction hole stops breathing in. In order to inhale paper more stable, the top seal installation of convulsions air chamber has suction plate 3, evenly be provided with the aperture of breathing in on the suction plate, suction plate 3 forms suction chamber 5 with the top of convulsions air chamber 9, and when suction hole 7 was opened, suction chamber 5 was the negative pressure chamber, the aperture of breathing in was breathed in, and the afterbody of paper is adsorbed on suction plate 3, because the aperture of breathing in evenly sets up, avoids the paper local sunken, but the tiling is on suction plate 3, if the afterbody is inhaled paper part setting between slow-speed conveying part and high-speed conveying part, suction plate 3 can also regard as the cardboard to use.

An air blowing component 6 is arranged above the tail paper absorbing component and plays an auxiliary role; the air blowing component 6 is matched with the tail paper absorbing component 13 for use, so that the tail of the paper is quickly and snugly placed on the front conveying belt 1 or the paper absorbing plate 3; the air blowing component 6 comprises an air nozzle, the air nozzle is connected with an air source, the air nozzle blows air from top to bottom, the tail of the paper is pressed downwards, and the air blowing frequency and time of the air nozzle are consistent with the air suction of the air suction hole.
