Abstract
The utility model relates to a roller type paper cutting mechanism for rewinder comprising a rotation roller for guiding the paper, which is characterized in that a braking roller is pressed onto therotation roller, the paper is clamped between the rotation roller and the braking roller, the braking roller is connected to the braking mechanism, and the braking mechanism forces the rotation speedof the braking roller to be reduced instantly, but the rotation is not stopped. During paper cutting, the mechanism forces the rotation speed of the braking roller to be reduced instantly, so that thepaper between the scroll and the rotation roller is pulled off. Because the braking roller never stops rotation during paper cutting, paper subsequently transferred will not be stacked in the seam between the braking roller and the rotation roller. Compared with the block type paper cutting mechanism in the prior art, the mechanism is more beneficial to structure simplification without the need of braking roller.
Description
Technical field
The utility model relates to the paper breaking mechanism that being used in the rewinding machine in the paper products Fabricating machinery, particularly rewinding machine break paper roll.
Background technology
Rewinding machine is in paper product such as production toilet paper, and whenever continuous paper rewinding being become coil paper volume back just the paper of paper roll afterbody must be broken, this process is finished by the paper breaking mechanism of rewinding machine.In order to realize that existing rewinding machine adopts the pressing block type paper breaking mechanism while rotating the break fast quick-break paper function of paper of paper roll.This paper breaking mechanism utilizes briquetting by on the live-rollers that is pressed in the traction paper, relies on briquetting and live-rollers to the clamping action of paper, forces the paper roll of rotation that the paper of paper roll afterbody is broken.The shortcoming of this paper breaking mechanism is that briquetting can only be pushed live-rollers the short time, because if the briquetting live-rollers of failing in time to leave behind the disconnected paper, the follow-up paper that sends will be piled up in the crack between briquetting and the live-rollers, yet briquetting is pushed the time of live-rollers again can not be too short, otherwise briquetting just leaves live-rollers before paper is thoroughly broken, and causes disconnected paper failure.
Summary of the invention
The purpose of this utility model is to pile up behind disconnected paper for rewinding machine provides a kind of paper of both can having avoided, and can guarantee the roller paper breaking mechanism of disconnected paper success again.
For this reason, the roller paper breaking mechanism of rewinding machine comprises the live-rollers of a guiding paper, especially, on live-rollers by being pressed with brake roller, paper clamp is between live-rollers and brake roller, and brake roller is connecting braking mechanism, and braking mechanism forces the rotating speed moment reduction of brake roller but do not stop operating.Principle of work of the present utility model is such: the paper rewinding is become in the process of paper roll at rewinding machine, braking mechanism is still inoperative to brake roller, brake roller rotates with identical excircle linear velocity together with live-rollers, and brake roller can not produce pulling force to the paper between paper roll and live-rollers; When breaking paper, the braking mechanism action, force the rotating speed moment reduction of brake roller, so the friction force between brake roller and the paper will produce pulling force to the paper between paper roll and live-rollers, this moment is owing to paper roll is still rotating, so the paper between paper roll and live-rollers will be tauted and break, realize disconnected paper; Behind the disconnected paper, braking mechanism resets, because brake roller do not stop operating when disconnected paper, so the follow-up paper that sends can not be deposited in the crack between brake roller and the live-rollers.
The utility model has the advantages that and to realize while rotating the break fast quick-break paper function of paper of paper roll, can avoid again behind the disconnected paper sheet stacking taking place, and compare with the pressing block type paper breaking mechanism that existing rewinding machine adopts, the utility model can allow brake roller all the time by being pressed on the live-rollers, need not the travelling brake roller, more help simplified structure thus.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the braking mechanism embodiment among Fig. 1;
Fig. 3 is another embodiment of the braking mechanism among Fig. 1.
The specific embodiment
Referring to Fig. 1, rewinding machine has three identical 1,2,3, three live-rollerss of live-rollers of excircle linear velocity and clips paper roll 4 rotations together, with this 5 rewinding of continuous paper is become paper roll.Pushing brake roller 6 on the live-rollers 1 of guiding paper, brake roller 6 and live-rollers 1 are formed the roller paper breaking mechanism together.Paper 5 is clipped between live-rollers 1 and the brake roller 6.Brake roller 6 can be a roll body that freely rotates, and fully by live-rollers 1 driven rotary, perhaps also brake roller 6 can be connected with actuating unit.If brake roller 6 is connected with actuating unit, then should make brake roller 6 the excircle linear velocity identical with live-rollers 1.Brake roller 6 is connecting braking mechanism 7.Fig. 1 only schematically uses a box indicating braking mechanism.The concrete structure of braking mechanism can be selected for use from the mechanism with braking function of routine.Fig. 2 shows a kind of embodiment of braking mechanism.In Fig. 2, braking mechanism comprises a rotating shaft 8, is fixed with friction wheel 9 in the rotating shaft 8, near friction wheel one friction lining 10 is arranged, when friction lining 10 was pressed on the friction wheel 9, cliding friction took place with friction wheel 9 in friction lining 10, and countershaft 8 plays brake action but rotating shaft 8 is stopped operating.Rotating shaft 8 among Fig. 2 can be the rotating shaft of the brake roller 6 among Fig. 1, also can be a rotating shaft that constitutes interaction relation by gear transmission, chain-driving or belt-driving with brake roller 6.Fig. 3 shows the embodiment of another kind of braking mechanism.In Fig. 3, braking mechanism has adopted free-wheel clutch, and free-wheel clutch has a friction disc 11 and a rolling disc 12, and friction disc 11 is fixed on the movable axis that can move axially but can not rotate 13, and rolling disc 12 is fixed in the rotating shaft 14.When free-wheel clutch meshed, friction disc 11 leaned against on the rolling disc 12, and friction disc 11 with rolling disc 12 cliding friction takes place, and countershaft 14 plays brake action but rotating shaft 14 is stopped operating.Rotating shaft 14 among Fig. 3 can be the rotating shaft of the brake roller 6 among Fig. 1, also can be a rotating shaft that constitutes drive connection by gear transmission, chain-driving or belt-driving with brake roller 6.In addition to the implementation, can also constitute braking mechanism with servomotor, that is rotate with the brake roller among driven by servomotor Fig. 16, the premium properties that utilizes servomotor to have the rotating speed sudden change is realized the braking function to brake roller 6, in this case, servomotor had both constituted the actuating unit that drives brake roller 6 rotations, constituted the braking mechanism of the rotating speed moment reduction that forces brake roller 6 again.
