Detailed ways

The relevant details and working principles of the embodiments and embodiments of the present invention will be described below with reference to the accompanying drawings. The paper stacking mechanism includes a slow-speed conveying part 11 and a high-speed conveying part 12, the slow-speed conveying part includes a front conveying belt 1, and the high-speed conveying part 12 adopts a paper feeding roller or a conveying belt. The conveying speed of the conveying member is faster than the speed of the slow conveying member. A tail suction member 13 is provided at the input end of the slow conveying member 11 or between the high speed conveying member and the slow conveying member. The tail suction member includes There are suction holes 7 for intermittent suction. If the tail suction member 13 is arranged at the input end of the slow conveying member 11, there are two cases here. The first is that the front conveyor belt 1 is provided with air holes, and the tail conveying member is arranged in the front conveyor belt. The air holes are communicated with the suction holes 7; the second type, the front conveyor belt 1 has several groups, and the tail suction parts 13 are arranged between the adjacent front conveyor belts 1; when the paper 2 enters the front conveyor belt , the suction hole 7 sucks in, the tail of the paper 2 is adsorbed and placed on the front conveyor belt 1, and then the suction hole stops sucking, so as to avoid affecting the conveying of the paper and the overlapping of the next paper. , the paper 2 is transported forward by the front conveyor belt 1, when the next paper enters the front conveyor belt, it will not hit the previous paper, but overlap the tail of the previous paper. If the tail suction part 13 is arranged between the slow conveying part and the high speed conveying part, when the front end of the paper 2 enters the front conveying belt 1, the suction hole 7 sucks in air, the tail of the paper is sucked downward, and then the suction hole 7 Stop inhaling, when the next paper enters the low-speed conveying part 11 from the high-speed conveying part 12, the previous paper has completely entered the front conveying belt 1, and the head of the next paper just overlaps the previous paper. tail. The existing paper enters the low-speed conveying part from the high-speed conveying part, and the paper will be scratched by the conveying belt or the pressure roller during the deceleration process, and the tail suction part 13 of the present utility model absorbs the tail of the paper by suction, so that the paper is successfully decelerated, In this way, the paper can be prevented from being damaged during the deceleration process. Therefore, the paper suction part 13 at the tail can not only realize the stable overlapping of the following paper and the previous paper, but also can reduce the speed of the paper by the paper suction part at the tail, so as to prevent the paper from decelerating. Damaged in the process, improve the paper quality of the slitting machine.

The paper suction part at the tail also includes a suction air chamber 9, which is connected to the suction fan 14, and the suction holes 7 are arranged on the suction air chamber 9. Since the paper has a certain width, it is To ensure stable adsorption, a plurality of the suction holes 7 can be set, and the number of suction holes can be set according to requirements. Consistent with the number of suction holes 7, the baffle 4 blocks the suction holes and the suction holes do not inhale. When the suction holes are communicated with the air extraction chamber, the suction holes 7 inhale, so that intermittent suction is realized. ; The baffle 4 can be a lift type, the baffle moves up to block the suction hole, the suction hole does not inhale, and when the baffle moves down, the suction hole inhales, in this embodiment, the baffle The plate 4 is connected to the power member that drives its rotation, and the power member can be a motor 10. The baffle plate is provided with a through hole 8. When the baffle plate 4 is rotated until the through hole 8 is opposite to the suction hole 7, the suction hole 7 communicates with the air extraction air chamber 9. When the through hole on the baffle 4 is staggered from the suction hole, the suction hole 7 is blocked by the baffle, and the suction hole stops suction. In order to make the paper suction more stable, a suction cardboard 3 is sealed and installed above the suction air chamber, and suction holes are evenly arranged on the suction cardboard. The suction cardboard 3 and the upper part of the suction air chamber 9 form a suction paper cavity 5. When the suction hole 7 is opened, the suction paper cavity 5 is a negative pressure cavity. It is laid flat on the suction board 3. If the tail suction part is arranged between the slow-speed conveying part and the high-speed conveying part, the suction board 3 can also be used as a pass-through board.

An air blowing part 6 is arranged above the paper suction part at the tail, and the air blowing part plays an auxiliary role; On the front conveyor belt 1 or on the suction cardboard 3; the air blowing part 6 includes an air nozzle, the air nozzle is connected with the air source, and the air nozzle blows air from top to bottom, so that the tail of the paper is pressed down, The blowing frequency and time of the air nozzle are consistent with the inhalation of the air intake hole.

Referring to Figures 1-3, the paper after slitting is transported forward by the paper feed roller, the head of the paper 2 enters the front conveyor belt 1, the suction hole 7 is opened, the suction hole is inhaled, and the air nozzle Blow air to make the end of the paper stick down on the suction board 3, then the suction hole 7 is closed, the suction hole stops sucking, the air nozzle stops blowing, the front conveyor belt 1 transports the paper forward, and the paper 2 is completely Entering the front conveyor belt, the latter paper is also fed by the feeding rollers. Because the tail of the former paper is attached to the front conveyor belt, the head of the latter paper will overlap the front conveyor belt when it enters the front conveyor belt. The tail, likewise, the tail of the following paper is adsorbed on the suction cardboard, and then completely enters the front conveyor belt 1, and the overlapping operation is performed in this way.
