Description

Technical Field

[0001] The utility model relates to a slitting machine, in particular to a paper conveying mechanism of a slitting machine with high stability. Background Art

[0002] The slitting machine is a special equipment for cutting paper. After the paper is cut, it needs to be transported through a conveying mechanism. The traditional conveying mechanism mainly includes a high-speed conveyor belt and a low-speed conveyor belt. The high-speed conveyor belt receives the paper that has been cut from the slitting mechanism, and then sends the paper to the low-speed conveyor belt. The low-speed conveyor belt sends the paper to the paper collection mechanism for stacking and collection. In order to achieve the deceleration of the paper from the high-speed conveyor belt to the low-speed conveyor belt and the stability of its transportation, the traditional method is to use a pressure wheel mechanism to press the paper, but this structure easily causes indentations on the paper, affecting the quality of the paper. Utility Model Content

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the utility model is to provide a paper conveying mechanism of a high-stability slitting machine for solving the above-mentioned problems.

[0004] To this end, the utility model is implemented by adopting the following scheme:

[0005] The paper conveying mechanism of the high-stability slitting machine includes a high-speed conveyor belt and a low-speed conveyor belt arranged in front and behind, and is characterized in that a first paper suction deceleration component is arranged between the high-speed conveyor belt and the low-speed conveyor belt, and a second paper suction deceleration component is arranged corresponding to the feeding end of the low-speed conveyor belt. When the previous paper is conveyed on the low-speed conveyor belt and its end is completely covered and sucked by the second paper suction deceleration component, the next paper is just sent out from the high-speed conveyor belt and partially covers the end of the previous paper.

[0006] The first paper suction deceleration component comprises a paper board, a first suction hole is formed on the paper board, and a first negative pressure component is provided corresponding to the paper board to generate negative pressure at the first suction hole.

[0007] The second paper suction deceleration component includes an adsorption plate arranged below the feeding end of the low-speed conveyor belt, the adsorption plate is provided with a second adsorption hole, and a second negative pressure component is arranged corresponding to the adsorption plate to generate negative pressure at the second adsorption hole.

[0008] A paper pressing belt is arranged above the high-speed conveyor belt and the low-speed conveyor belt.

[0009] The paper conveying mechanism of the high-stability slitting machine of the above technical solution performs the first adsorption on the paper sent from the high-speed conveyor belt through the first adsorption hole on the paperboard, thereby realizing a first-level deceleration of the high-speed moving paper, so that it can be decelerated and sent to the low-speed conveyor belt, and when conveyed on the low-speed conveyor belt, it can be adsorbed for the second time through the second adsorption hole on the adsorption plate, so that the secondary deceleration of the paper is adapted to the conveying speed of the low-speed conveyor belt. The two deceleration operations make the deceleration of the paper smoother, avoiding wrinkles and deformation of the paper, and at the same time, it can also ensure that the left and right position of the paper is not easily offset when it is sent to the low-speed conveyor belt, thereby ensuring the stability of paper transportation.

[0014] As shown in the figure, the paper conveying mechanism of the high-stability slitting machine disclosed by the utility model includes a high-speed conveyor belt 1 and a low-speed conveyor belt 7 arranged in front and behind, and a first paper suction deceleration component is arranged between the high-speed conveyor belt 1 and the low-speed conveyor belt 7. In this embodiment, the first paper suction deceleration component includes a paper board 3, and a first adsorption hole 4 is opened on the paper board 3. A first negative pressure component is arranged corresponding to the paper board 3 and a negative pressure is generated at the first adsorption hole 4. The first negative pressure component includes a first negative pressure bin, and a first negative pressure cavity is arranged in the first negative pressure bin. The first negative pressure cavity is connected to the first adsorption hole 4, and the first negative pressure cavity is connected to the first negative pressure machine through an air pipe. By controlling the operation of the first negative pressure machine, a negative pressure is generated in the first negative pressure cavity, so that an adsorption force is generated at the first adsorption hole 4 to adsorb and decelerate the paper. A second paper suction deceleration component is provided at the feed end of the corresponding low-speed conveyor belt. When the previous paper is conveyed on the low-speed conveyor belt and its end is completely covered and sucked by the second paper suction deceleration component, the next paper is just sent out from the high-speed conveyor belt and partially covers the end of the previous paper. The second paper suction deceleration component includes an adsorption plate 5 provided below the feed end of the low-speed conveyor belt 7. The adsorption plate 5 is provided with a second adsorption hole 6. A second negative pressure component is provided corresponding to the adsorption plate 5 and a negative pressure is generated at the second adsorption hole 6. The second negative pressure component includes a second negative pressure bin 9. The second negative pressure bin 9 has a second negative pressure cavity. The second negative pressure cavity is connected to the second adsorption hole 6. The second negative pressure cavity is connected to the second negative pressure machine through an air pipe. By controlling the operation of the second negative pressure machine, a negative pressure is generated in the second negative pressure cavity, so that a negative pressure is generated at the second adsorption hole 6, and the paper is adsorbed and decelerated. A paper pressing belt 2 is provided above the corresponding high-speed conveyor belt 1 and the low-speed conveyor belt 7 to further ensure that the paper will not float during the conveying process.

[0015] The working principle of the utility model is as follows: the cut paper 10 is first conveyed by the high-speed conveyor belt 1. When the paper is conveyed to the paperboard 3, the negative pressure generated by the first adsorption hole 4 adsorbs and decelerates the paper. When the decelerated paper is conveyed to the low-speed conveyor belt 7, the adsorption plate 5 is completely covered by the end of the previous paper 12, ensuring that the front end of the next paper 11 just covers the end of the previous paper, thereby realizing partial stacking of the paper. After that, as the low-speed conveyor belt 7 drives the paper to continue to be conveyed, the second adsorption hole 6 on the adsorption plate 5 adsorbs and decelerates the next paper 11, causing the speed of the paper to decrease. To adapt to the conveying speed of the low-speed conveyor belt 7, and ensure that the left and right positions of the paper will not deviate when it first enters the low-speed conveyor belt 7, and finally stably convey it to the paper receiving mechanism 8 for paper collection, and as the previous paper 12 separates from the adsorption plate 5, the next paper 11 contacts the adsorption plate 5 to achieve deceleration, and at this time the adsorption holes at the paperboard 3 stop generating adsorption force, ensuring that the next paper 11 can be driven by the low-speed conveyor belt 7 to move, until the next paper 11 is separated from the adsorption plate 5, the adsorption plate 5 generates adsorption force again to adsorb and decelerate the subsequently conveyed paper.

[0016] The structure of the utility model realizes the secondary deceleration of the paper to adapt to the conveying speed of the low-speed conveyor belt. The two deceleration operations make the deceleration of the paper smoother, avoiding wrinkles and deformation of the paper. At the same time, it can also ensure that the left and right positions of the paper are not easily offset when it is sent to the low-speed conveyor belt, thereby ensuring the stability of paper transportation.
