when the piled paper needs to be processed, the cutting mechanism stops working, the second power roller 8 gradually reduces the rotation speed and finally stops rotating, but at the moment, the first power roller 3 still continues to rotate to lead out the printing paper, at the moment, the drum 13 on the left side of the first outer frame 24 continues to rotate at the original speed, while the drum 13 on the right side of the first outer frame 24 gradually reduces the rotation speed and finally stops rotating, at the moment, the drum 13 on the left side can continue to drive the transverse shaft 29 to rotate, the transverse shaft 29 can drive the rotating shaft 23 to rotate through the transverse shaft 29, and the transverse shaft 29 is connected with the sleeve 15 through the one-way bearing 28, even when the drum 13 and the sleeve 15 stop rotating, the transverse shaft 29 on the right side can rotate relative to the sleeve 15 through the one-way bearing 28, at the moment, the transverse shaft 29 on the right side is in a rotating state relative to the sleeve 15 on the right side, and further the rotating shaft 23 on one end of the transverse shaft 29 is in a rotating state relative to the second outer frame 36, the rotating shaft 23 is provided with a U-shaped protrusion, so when the rotating shaft 23 rotates relative to the second frame 36, the two second pull rods 30 can be driven to move up and down in a staggered manner, and further the second sliding plate 31 is driven to move up and down in a staggered manner in the chambers at the two sides of the partition plate 34, when the second sliding plate 31 slides down, external air can enter the second frame 36 through the air inlet pipe 35, and when the second sliding plate 31 moves up, the air can be conveyed to the inside of the three-way pipe 32 and further conveyed to the inside of the exhaust hood 16 through the connecting pipe 33, and through the two second sliding plates 31 which slide up and down in a staggered manner, the continuous conveying of the air to the inside of the exhaust hood 16 is facilitated, and the air in the inside of the right exhaust hood 16 can be conveyed to the inside of the first frame 24 through the guide pipe 27 and placed at the bottom of the first sliding plate 26, so that the air pressure at the bottom of the first sliding plate 26 is increased, the first slide plate 26 can be driven to move upwards, the first slide plate 26 can be driven to move the first pull rod 25 upwards, thereby driving the hanger and the driving roller 22 at the bottom thereof to move upwards, thereby storing the redundant paper led out by the first power roller 3, when the gas in the draft tube 27 is conveyed to the inside of the draft cavity 40 through the gas inlet 41, under the pressure of the gas, the sealing plate 46 will move downwards along the guide rod 45 against the force of the spring 44, so that the top of the sealing plate 46 is separated from the bottom of the inner baffle 39, and at this time, the gas inside the guide cavity 40 can enter the inside of the first outer frame 24 through the space between the inner baffle 39 and the sealing plate 46, thereby gradually moving the first slide plate 26 upward, and when the first slide plate 26 is moved upward, the top of the first slide plate 26 can be discharged through the gap between the sealing plate 46 and the bottom of the fixing plate 43.
After the stacked printing paper is processed, the cutting mechanism and the second power roller 8 work again, at this time, the rotating speed of the drum 13 on the right side is gradually increased, the rotating speed of the rotating shaft 23 on the right side is gradually reduced relative to the rotating speed of the drum 13 on the right side, so that the frequency of the rotating shaft 23 driving the second pull rod 30 to move up and down is reduced, the amount of gas conveyed to the flow guide pipe 27 and the first outer frame 24 through the second outer frame 36 is reduced, at this time, the upward moving speed of the first sliding plate 26 is reduced, and the rotating speed difference between the first power roller 3 and the second power roller 8 is reduced due to the re-rotation of the second power roller 8, so that the speed of the storing mechanism 12 for storing the paper is gradually reduced and is just matched with the first sliding plate 26 with the reduced ascending speed.
When the rotating speed of the second power roller 8 exceeds the rotating speed of the first power roller 3, the speed of the rotating drum 13 on the right side gradually exceeds the speeds of the horizontal shaft 29 and the rotating shaft 23, at this time, the rotating drum 13 and the sleeve 15 can drive the horizontal shaft 29 to synchronously rotate through the one-way bearing 28, so that the rotating shaft 23 on the right side and the second outer frame 36 on the right side synchronously rotate, and the second sliding plate 31 cannot be driven to move in the second outer frame 36, so that the gas conveying to the inside of the guide pipe 27 is stopped, at this time, the horizontal shaft 29 on the right side can drive the rotating shaft 23 to synchronously rotate, so that the horizontal shaft 29 on the left side rotates relative to the sleeve 15 through the one-way bearing 28, at this time, the horizontal shaft 29 on the left side rotates relative to the sleeve 15 on the left side, so that the rotating shaft 23 rotates relative to the sleeve 15 on the left side, and similarly, at this time, the rotating shaft 23 can drive the second sliding plate 31 on the left side to move up and down in the second outer frame 36 on the left side, so as to convey the inside of the first outer frame 24 through the guide pipe 27 and place at the bottom of the first sliding plate 26, can press first slide 26 and move down, can drive first pull rod 25 through first slide 26 and move down, and then drive the drive roller 22 downstream of gallows and its bottom, and then the printing paper release that will store, when drive roller 22 resets gradually, second power roller 8 with slow down gradually and with first power roller 3 synchro-rotation, the rotary drum 13 synchro-rotation of both sides this moment gets back to initial operating condition again.
Can realize the pile up of paper under the condition of not shutting down through above-mentioned structure to the difference in rotational speed through both sides rotary drum 13 realizes, makes reciprocating of drive roller 22 and the difference in rotational speed dynamic balance of both sides rotary drum 13, can accomplish the storage and the release to the paper automatically, and does not need extra control unit and power part, connects more stably, and is convenient for maintain, easily operates.
