Detailed description of the invention
Embodiment one
See Fig. 1, according to a kind of coreless rolls rewinding machine described in the utility model, comprise rewinding top roll 1 and rewinding lower roll 2, be provided with the curved surface 3 close with the roll surface of rewinding top roll in the below of rewinding top roll 1.Gap between the roll surface of rewinding top roll 1 and curved surface 3 forms a roll set passage 4.Fig. 1 (comprising Fig. 3 to Fig. 8, Figure 10 to Figure 12) has a mind to be exaggerated the gap between rewinding top roll 1 and curved surface 3, represents roll set passage 4 with clear.The exit end of roll set passage 4 is facing to the roll gap between rewinding top roll 1 and rewinding lower roll 2.From the arrival end of roll set passage 4 to exit end, change from small to big in the gap between curved surface 3 and rewinding top roll 1.In the position near roll set passage 4 arrival end, curved surface 3 is provided with the air suctiton inlet 5 that a row adsorbs paper.Simultaneously see Fig. 1, Fig. 2, this row's air suctiton inlet is made up of multiple air suctiton inlet 5 arranged along the trend (being namely parallel to the axis of rewinding top roll 1) perpendicular to roll set passage 4.All air suctiton inlets 5 are connected with extraction equipments such as vacuum pump (not shown)s.
Before roll set, the forming process of paper head as shown in Figure 3, after last coil paper rolls up 6 rewinding to required diameter, by accelerating the modes such as the rotating speed of paper roll 6, makes the paper of this paper roll afterbody disconnect, so define the head 7 of the follow-up paper brought.After paper head 7 is formed, last coil paper volume 6 is just sent rewinding machine.
Paper head 7 shown in Fig. 3 starts roll set process after being formed immediately.As shown in Figure 4, the air suctiton inlet 5 on curved surface 3 is utilized to hold the position of the close paper head of paper, make to pile up in the gap of the follow-up paper sent here between rewinding top roll 1 and curved surface 3 to form fold 8, fold 8 rubs into the paper roll core 9 shown in Fig. 5 by the rewinding top roll 1 rotated again in roll set passage 4.The paper roll core 9 of new formation, under the rubbing of rewinding top roll 1, continues along curved surface 3 rolls forward.Along with the rolling of paper roll core 9, the follow-up paper continuous reeling sent here is on paper roll core 9.Finally, roll large paper roll core and roll into roll gap between rewinding top roll 1 and rewinding lower roll 2 from the exit end of roll set passage 4, form the new paper roll 10 of shown in Fig. 6.Afterwards, the new coil paper volume 10 formed rubs lower continuation rewinding jointly just at rewinding top roll 1 and rewinding lower roll 2, until reach required diameter, completes rewinding process.
Embodiment two
See Fig. 7, the present embodiment, on the basis of embodiment one, adds many row's air suctiton inlet 5a, 5b, 5c, and many row's air suctiton inlet 5a, 5b, 5c move towards arrangement along roll set passage 4.Each row's air suctiton inlet, all as Fig. 2, is made up of along the air suctiton inlet 5 moving towards to arrange perpendicular to roll set passage 4 multiple.Compared with embodiment one, many row's air suctiton inlets can expand the region of the absorption paper of curved surface 3, improve stability and the reliability of roll set.
The roll set process of the present embodiment is identical with embodiment one.
Embodiment three
See Fig. 8 and composition graphs 9, the present embodiment, on the basis of embodiment one, curved surface 3 adds friction shoe 11.Friction shoe 11 is fixed on the position of the arrival end of the close roll set passage 4 of curved surface 3, protruding towards rewinding top roll 1.See Figure 10, after last coil paper rolls up 6 rewinding, drive friction shoe 11 to push up the roll surface being pressed onto rewinding top roll 1 by curved surface 3, utilize the top of the afterbody paper of friction shoe 11 pairs of paper rolls 6 to press, the afterbody paper of paper roll 6 is disconnected, forms new paper head 7.
The present embodiment can increase equally as shown in Figure 7 on curved surface 3 arranges air suctiton inlet more.
The roll set process of the present embodiment is identical with embodiment one.
Embodiment four
See Figure 11, the present embodiment is the same with embodiment three, is also to utilize friction shoe to realize disconnected paper, but friction shoe 11 is fixed on a swivel arm 12 by the present embodiment.During disconnected paper, swivel arm 12 13 rotates around the shaft, friction shoe 11 is rotated the roll surface being pressed onto rewinding top roll 1 to top, and the afterbody paper of the paper roll 6 making rewinding complete with this disconnects.Swivel arm 12 in Figure 11 seems intersection-type collision with curved surface 3, but in fact curved surface 3 has pectination, swivel arm 12 is arranged with multiple along the axially spaced-apart of rewinding top roll 1, and each swivel arm 12 passes from the pectination of curved surface 3, and swivel arm 12 and curved surface 3 can not collide.
The roll set process of the present embodiment is identical with embodiment one.
Embodiment five
See Figure 12, the present embodiment is on the basis of embodiment one, multiple air suctiton inlet 14 is added at the roll surface of rewinding top roll 1, these air suctiton inlets 14 are only when rotating the effect just having air-breathing to the scope of angle beta, paper is adsorbed on securely on rewinding top roll 1 in the scope of angle beta, strengthens the tractive force of rewinding top roll 1 pair of paper.
The roll set process of the present embodiment is identical with embodiment one.
