Description
Technical Field
The invention relates to the field of papermaking machinery, in particular to a speed reducing mechanism of a paper splitting machine.
Background
The paper sheets of the roll paper splitting machine pass through a fast delivery belt to a slow delivery belt after being cut off by a transverse cutter, and then reach a paper stacking table to be stacked and stacked. The speed of the paper from the fast delivery belt to the stacking table must be reduced, otherwise the paper is too fast to impact the baffle of the stacking table, so that the damaged paper becomes waste. Therefore, the paper must be decelerated from the fast belt to the jogger table by the slow delivery belt. Deceleration requires a slower delivery belt speed than a faster delivery belt speed, but at this time the paper does not have an external force applied and can fly out of the deceleration mechanism.
The existing web splitting machine adopts an external force applying method that a pressing wheel is arranged on a slow delivery belt, and the friction force is generated between the pressing wheel and paper to decelerate the paper. The paper cut by the roll paper cutting machine is generally coated white cardboard, coated paper and the like. The coated surface of the paper is smooth, and light spots or pressure wheel marks can be generated by the friction between the speed-reducing pressure wheel on the slow delivery belt and the paper. Coated paper with light spots or pinch roller prints can cause poor printing ink during printing, or the printed matter still sees the light spots and the pinch roller prints after printing, resulting in poor printing effect.
Therefore, a speed reducing mechanism capable of solving the problem of producing spots or pinch roller marks in the production of coated paper is needed for the roll paper splitting machine.

Detailed Description
The present invention will be described in detail and specifically with reference to the following examples so as to facilitate the understanding of the present invention, but the following examples do not limit the scope of the present invention.
Example 1
The embodiment discloses a speed reducing mechanism of a paper splitting machine, which comprises a slow delivery belt 1, a vacuum suction device 2 and a bracket 3. The vacuum suction device 2 is provided below the slow delivery belt 1, and sucks the paper sheet on the slow delivery belt 1. The support 3 supports the slow conveyor belt 1 and the vacuum suction device 2.
The vacuum suction apparatus 2 includes a vacuum plate 21, a vacuum pump 22, and a duct 23 connected to the vacuum pump 22. The upper surface of the vacuum plate 21 is provided with a suction hole 24, and the vacuum plate 21 forms a downward suction force at the suction hole 24 after being sucked by the duct 23.
The vacuum plate 2 has two, including a first vacuum plate 25 and a second vacuum plate 26. One end of the slow delivery belt 1 is a paper feeding end 11, and the other end is a paper discharging end 12, and two ends of the slow delivery belt 1 are provided with a paper feeding end belt guide roller 13 and a paper discharging end belt guide roller 14. The first vacuum plate 25 is disposed outside the sheet-feeding-end belt guide roller 13, and the second vacuum plate 26 is disposed on the other side of the sheet-feeding-end belt guide roller 13.
The first vacuum plate 25 is obliquely disposed and gradually rises in a direction close to the sheet feeding end belt guide roller 13. In this embodiment, the slow transfer belt 1 is a perforated strip belt. The vacuum pump 22 is a variable frequency vacuum pump.
As shown in fig. 2 and 3, after being cut by the cross blade 4, the sheets are first conveyed by the fast conveyance belt 5, then decelerated by the slow conveyance belt 1, and stacked on the stacker table 6. The rapid delivery belt 5 drives the paper to move at a fast speed, when the paper moves to the first vacuum plate 25, the first vacuum plate 25 adsorbs the paper downwards, the corner position of the paper is fixed, the paper is prevented from flying, and the paper can be decelerated well due to the inclined arrangement of the first vacuum plate 25. The control of the speed of the fast delivery belt 5 and the suction force of the vacuum pump 22 allows the paper sheets to be automatically pressed and stacked on the first vacuum plate 25 for subsequent stacking. Then the paper sheet continues to move to the position of the slow delivery belt 1 due to the inertia of the paper sheet; at this time, the second vacuum plate 26 again sucks the sheet toward the slow delivery belt 1, and keeps the same moving speed of the sheet as the slow delivery belt.
The distance between the first vacuum plate 25 and the second vacuum plate 26 can be adjusted by itself according to the size of the paper, so as to achieve a better deceleration effect, and the interval of 15cm is generally suitable.
