The utility model content

The purpose of this utility model is that above-mentioned roll set mechanism is improved, for rewinding machine provides more failure-free coreless rolls roll set mechanism of a kind of roll set.

The utility model is achieved in that the coreless rolls roll set mechanism of rewinding machine comprises rewinding top roll and the rewinding lower roll that is parallel to each other, above the rewinding lower roll, be provided with airduct towards canyon, gap location setting between rewinding top roll and rewinding lower roll helps roll bending, help the leading edge of roll bending to be close to the face of cylinder of rewinding lower roll, especially, the face of cylinder of rewinding top roll and rewinding lower roll all is evenly equipped with air suctiton inlet, all air suctiton inlets are communicated to the end face of its place roll body, in the end of approaching rewinding top roll and rewinding lower roll, be fixed with a suspended hood respectively, the suspended hood part covers the close position that helps roll bending of roll body end face, with co-shaft-surface that is parallel to rewinding top roll and rewinding lower roll and the plane of passing through the leading edge that helps roll bending is dividing range, the overlay area of the suspended hood of roll end on the end face of rewinding top roll is positioned at a side that helps the roll bending place in the rewinding, and the overlay area of the suspended hood of roll end on the end face of rewinding lower roll is positioned at opposite side under the rewinding.

Roll set principle of the present utility model is: the suspended hood by roll end in the rewinding is bled to the air suctiton inlet of rewinding top roll, make paper be close to the rewinding top roll, and the coverage of suspended hood on rewinding top roll end face guaranteed the air suctiton inlet of rewinding top roll and in time died, and the paper head can be blown off to the rewinding lower roll by airduct; On the other hand, the suspended hood of roll end is bled to the air suctiton inlet of rewinding lower roll under the rewinding, make the paper head of falling on the rewinding lower roll be close to the rewinding lower roll, and the coverage of suspended hood on rewinding lower roll end face guaranteed the air suctiton inlet of rewinding lower roll and in time died, and makes the paper head be helped roll bending to scoop up; So, along with the continuous rotation of rewinding lower roll and rewinding top roll, paper is constantly sent in the gap between rewinding top roll and the rewinding lower roll, and then is rubbed and form new paper roll, realizes roll set.

This shows, the utility model is not the air-flow that relies on airduct to blow out, but mainly relies on the swabbing action of the air suctiton inlet of rewinding lower roll, makes the paper head be close to the rewinding lower roll, therefore the utility model can reduce the current rate that airduct blows out, and avoids the excessive drawback that causes of current rate; On the other hand, the rewinding top roll has guaranteed that to the adsorption of paper paper can not separate with the rewinding top roll prematurely, so the utility model has improved the reliability of roll set process.

As further improvement of the utility model, local rough surface can be set, the rough surface slight concave that this is local on the face of cylinder of rewinding top roll and rewinding lower roll.

The specific embodiment

The coreless rolls roll set mechanism of rewinding machine described in the utility model as shown in Figure 3, comprise the rewinding top roll 1 and the rewinding lower roll 2 that are parallel to each other, above the rewinding lower roll, be provided with airduct 3 towards canyon, gap location setting between rewinding top roll and rewinding lower roll helps roll bending 4, helps the leading edge of roll bending 4 to be close to the face of cylinder of rewinding lower roll 2.Simultaneously referring to Fig. 3, Fig. 4, the face of cylinder of rewinding top roll 1 is evenly equipped with air suctiton inlet 6, and air suctiton inlet 6 is communicated to the air extractor vent 7 on the end face of rewinding top roll.Be fixed with a suspended hood 8 in the end of approaching the rewinding top roll, suspended hood 8 both can only be arranged in an end of rewinding top roll 1, also can be arranged in the two ends of rewinding top roll 1.Suspended hood 8 parts cover the close position that helps roll bending 4 of the end face of rewinding top roll 1.The same air suctiton inlet 9 that is evenly equipped with the rewinding top roll in the face of cylinder of rewinding lower roll 2, air suctiton inlet 9 are communicated to the air extractor vent 10 on the end face of rewinding lower roll.Structure shown in Figure 4 is equally applicable to the rewinding lower roll.Be fixed with a suspended hood 11 in the end of approaching rewinding lower roll 2, suspended hood 11 both can only be arranged in an end of rewinding lower roll 2, also can be arranged in the two ends of rewinding lower roll 2.Suspended hood 11 parts cover the close position that helps roll bending 4 of the end face of rewinding lower roll 2.With co-shaft-surface that is parallel to rewinding top roll and rewinding lower roll and the plane M-N that passes through the leading edge that helps roll bending is dividing range, the overlay area of suspended hood 8 on the end face of rewinding top roll 1 is positioned at a side that helps roll bending 4 places, and the overlay area of suspended hood 11 on the end face of rewinding lower roll 2 is positioned at opposite side.Certainly, no matter be the zone of suspended hood 8 coverings or the zone that suspended hood 11 covers, all allow the small part zone and cross dividing range M-N, the zone that covers as the suspended hood among Fig. 38 just has small part to cross dividing range M-N.

" overlay area of suspended hood " described in the utility model is meant effective overlay area of suspended hood, is not the zone that appearance profile covered that refers to whole suspended hood.For example the profile of the suspended hood among Fig. 38 can become the hollow disk that a diameter equates with the rewinding top roll, from in appearance, the whole end face of rewinding top roll is all covered by suspended hood, but the coverage of the air suctiton inlet of suspended hood, just the effective coverage range of suspended hood remains coverage shown in Figure 3.

From Fig. 3 as seen, when the air extractor vent 7 on the rewinding top roll end face turned to the scope of suspended hood 8 coverings, the air suctiton inlet on the rewinding top roll face of cylinder that communicates with this air extractor vent produced suction, and paper 5 is adsorbed on the rewinding top roll 1; Leave the scope of suspended hood 8 coverings when the air extractor vent 7 on the rewinding top roll end face after, the air suctiton inlet forfeiture suction on the rewinding top roll face of cylinder that communicates with this air extractor vent, this moment, airduct 3 can blow off the paper head to rewinding lower roll 2.On the other hand, when the air extractor vent 10 on the rewinding lower roll end face turned to the scope of suspended hood 11 coverings, the air suctiton inlet on the rewinding lower roll face of cylinder that communicates with this air extractor vent produced suction, and the paper head is adsorbed on the rewinding lower roll 2; Leave the scope of suspended hood 11 coverings when the air extractor vent 10 on the rewinding lower roll end face after, the air suctiton inlet forfeiture suction on the rewinding lower roll face of cylinder that communicates with this air extractor vent, help roll bending 4 the paper head can be scooped up this moment, makes paper take place to curl.So, along with the continuous rotation of rewinding top roll 1 and rewinding lower roll 2, paper 5 is constantly sent in the gap between rewinding top roll and the rewinding lower roll, is finally rubbed to form new paper roll, finishes roll set.Behind the roll set, clip paper roll together by rewinding top roll 1, rewinding lower roll 2 and air roll 12 and rotate, until with the paper roll rewinding to required diameter.

From above-mentioned roll set process as seen, the utility model mainly utilizes the adsorption of 2 pairs of paper of rewinding lower roll, makes the paper head be close to the rewinding lower roll, can reduce the current rate that airduct 3 blows out thus, avoids the excessive drawback that causes of current rate; On the other hand, the utility model also utilizes the adsorption of 1 pair of paper of rewinding top roll, guarantee that paper can not separate with the rewinding top roll prematurely, so the utility model has improved the reliability of roll set process.

As further improvement of the utility model, local rough surface can be set, the rough surface slight concave that this is local on the face of cylinder of rewinding top roll and rewinding lower roll.Rough surface can increase the friction force between paper and the roll body, helps improving the reliability of roll set, and the rough surface slight concave can avoid helping the rough surface scraping of roll bending and rewinding lower roll.The distribution mode of rough surface on the face of cylinder of rewinding top roll and rewinding lower roll can be as shown in Figure 4.The local roughness surface on the roll body face of cylinder is represented at the position of the ruling that knits a net among Fig. 4, and the rough surface slight concave forms circular groove.
