Abstract
A dual-motor type fast paper breaking mechanism of a rewinder comprises three rotating rolls which clamp a paper scroll to rotate, one roll thereof is driven to rotate by two motors through a transmission mechanism, but only one motor thereof forms linkage relation with the roll simultaneously, the two motors respectively drive the rotating roll to rotate at high rotating speed and at low rotatingspeed, and when rotating at high rotating speed, the rotating roll drives the paper scroll to roll towards the direction breaking away from the three rotating rolls. The utility model utilizes two motors to change the rotating speed of the rotating rolls to realize paper breaking, and a pressing block is not needed to press the rotating rolls, thus completely solving the problem of paper accumulation existing in the existing pressing block type paper breaking mechanism, saving a mechanism for driving the pressing block to do reciprocating movement, and leading the paper breaking mechanism tobe more simplified.
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 while rotating the break fast quick-break paper function of paper of paper roll, existing rewinding machine in paper breaking mechanism with a briquetting by be pressed in the traction paper live-rollers on, rely on briquetting and live-rollers to the clamping action of paper, force the paper roll of rotation that the paper of paper roll afterbody is broken.The shortcoming of this pressing block type 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 for rewinding machine provides a kind of paper of avoiding the quick paper breaking mechanism of piling up of double motor type to take place behind disconnected paper.
The utility model is achieved in that the quick paper breaking mechanism of the double motor type of rewinding machine comprises three live-rollerss that clip the paper roll rotation together, especially, wherein a live-rollers passes through the transmission device driven in rotation by two motors, two motors rotate simultaneously, but have only one of them motor and this live-rollers to form interaction relation at synchronization, two motors drive this live-rollers respectively with high rotating speed and slow speed of revolution rotation, and high rotating speed is at least than slow speed of revolution fast 10%, when this live-rollers of one of them motor-driven rotates with slow speed of revolution, the excircle linear velocity of this live-rollers rotation equals the excircle linear velocity of other two live-rollerss, when this live-rollers of another motor-driven rotated with high rotating speed, this live-rollers ordered about paper roll and rolls towards the direction that breaks away from three live-rollerss.Principle of work of the present utility model is such: at rewinding machine continuous paper rewinding is become in the process of paper roll, three live-rollerss clip paper roll and rotate with identical excircle linear velocity, this moment, two above-mentioned motors all rotated, but have only one of them motor and live-rollers to form interaction relation, and by this motor-driven live-rollers rotation, another motor then breaks away from interaction relation with live-rollers; When breaking paper, an above-mentioned live-rollers and former drive motor break away from interaction relation, then form interaction relation with another motor, rotate with higher speed by this another motor-driven, so paper roll will roll out in the middle of three live-rollerss, because two above-mentioned motors are all rotating always, so behind the conversion motor, can improve the rotating speed of live-rollers moment, high in addition revolution ratio slow speed of revolution fast at least 10%, therefore the speed that rolls out in the middle of three live-rollerss of paper roll is very fast, causes the paper of paper roll afterbody to be tightened by moment and breaks, and realizes disconnected paper.This shows that the utility model need not to push live-rollers with briquetting, therefore solved the problem that paper is piled up fully between briquetting and 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, saved the reciprocating mechanism of driving briquetting, paper breaking mechanism is more simplified.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 realizes live-rollers and two embodiment that motor links respectively.
The specific embodiment
Referring to Fig. 1, the quick paper breaking mechanism of the double motor type of rewinding machine comprises three live-rollerss 1,2,3 that clip the paper roll rotation together.Wherein live-rollers 1 passes through belt 6,7 driven in rotation respectively by two motors 4,5.Except that belt gear, can also adopt conventional transmission devices such as gear drive, chain drive, synchronous belt drive mechanism.Two motor institute bonded assembly transmission devices both can be connected the same end of live-rollers 1 as shown in Figure 1 together, can be connected to company's end of live-rollers 1 again.Be connected with power-transfer clutch 8,9 between the rotating shaft of two motors 4,5 and the belt pulley respectively.During rewinding machine work, two motors 4,5 are all rotating always, but have only one of them motor institute bonded assembly clutches engaged at synchronization, make to have only one of them motor and live-rollers 1 to form interaction relation at synchronization.Motor 4 drives live-rollers 1 high speed revolution, and motor 5 drives live-rollers 1 low speed rotation, and high rotating speed is at least than slow speed of revolution fast 10%.For example the excircle linear velocity of live-rollers 1 is 100m/min during slow speed of revolution, and the excircle linear velocity of live-rollers 1 is at least 110m/min during then high rotating speed.When live-rollers 1 rotated with slow speed of revolution, the excircle linear velocity of live-rollers 1 equaled the excircle linear velocity of other two live-rollerss 2,3.When live-rollers 1 during, will order about paper roll 10 and roll towards the direction that breaks away from three live-rollerss to the right with high rotational speed.
Fig. 2 shows live-rollers 1 and two another embodiment that motor links respectively.In Fig. 2, the two ends of live-rollers 1 are connected with 11,12, two motors of power-transfer clutch (Fig. 2 is not shown) respectively and form interaction relation by power- transfer clutch 11,12 and live-rollers 1 respectively, but have only a clutches engaged at synchronization.
