Description

Rewinding machine

1, technical field

The utility model rewinding machine is the paper roll that is used for the big volume of wide cut burr that will produce on the paper machine line, launches again, vertically cut edge, segment again rewinding become the commodity paper roll.Be a kind of light industry and machinery equipment that belongs to paper production.

2, background technology

Rewinding machine is partly formed by moving back paper, rip cutting, coil paper, frame, transmission, tension force control etc., and its version is divided into single roller rewinding machine that single roller drives by bottom roller quantity and type of drive, two roller rewinding machines that two roller rewinding machines that single roller drives and two roller drive.

An air roll device all to be arranged above the bottom roller of three kinds of above-mentioned versions, compress the rewinding paper roll.The air roll structure generally is to affect the air roll lifting with hydraulic jack by chain, and air roll is floating being placed on the paper roll in the course of work, is moved upward along with reel diameter increases carrying on the back.The free degree that air roll is moved upward is unqualified, can beat in the space, influences the stable operation of rewinding machine, hinders rewinding machine and improves the speed of a motor vehicle and finished product volume quality.It is the fault of construction of rewinding machine.This novel practical rewinding machine is that roller structure is improved.

3, summary of the invention

The utility model rewinding machine is on the rewinding machine basis of traditional double bottom roller, and pressure roller is partly carried out the novel improvements design.

The utility model rewinding machine is cancelled former traditional form and is affected the floating roller structure that is placed on the paper roll with chain, employing on the upper bracket of body by adorning a swinging axle, at the two ends of swinging axle respectively by adorning a swing arm, the swing arm end is by the dress pressure roller parallel with swinging axle, the swing arm lifting and swinging spurs with two oil cylinders, making pressure roller is that the arc trajectory of radius is done parallel moving in the bottom roller sky with the swing arm, displacement, translational speed and pressure size can both reach controllable state by hydraulic system, make and to adopt different technological parameters, improve the rewinding quality the rewinding of different paper kinds.

Heavy line is the paper injection cabling among Fig. 1, and showing can be all feasible to coil paper portion at paper roll above and below paper injection.

Fine line circle among Fig. 1 on the paper loading rack 1 is the largest contours that shows the body paper frame, on two bottom rollers 9 and the fine line circle on the splicing car 16 be rewinding after the largest contours of paper roll, the swing arm 10 among Fig. 1, oil cylinder 12 with dashed lines show the extreme position of its swing.

5, the specific embodiment

The following mode of the utility model is implemented

With paper roll (paper roll to be processed) by being placed on the paper loading rack 1, the page head is involved (from the upper and lower of paper roll all can) in order by regulating roller 4; Jockey pulley 5; Exhibition paper bowl 6; The top of following cutter shaft 7 and preceding bottom roller 9, more than again the page hand scroll being enclosed to coil paper mandrel circumference one, put into the centre of two preceding bottom rollers 9, primer fluid compressing cylinder 12 is left behind swing arm 10, make pressure roller 11 push down the coil paper mandrel, again pneumatic upward dise knife is adjusted to predetermined finished roll degree place and fix, finish the whole back works before driving to this.

Open two frequency control motors 14 that drive two preceding bottom rollers 9, drive two preceding bottom rollers and rotate, rely on friction to drive the paper core rotation and make page rewinding again.

Starting frequency control on the paper loading rack 1 when driving two preceding bottom rollers 9 puts paper motor 15 and puts paper and rotate.

Because the frequency control motor of bottom roller 9 is selected its constant torque characteristic stage for use before driving, so under the certain situation of rotating speed, torque is constant, and it is also constant to lead the paper pulling force.Select for use the frequency control motor of putting paper with its constant output characteristic stage, along with the paper roll reduced radius, rotating speed rises.Because it is constant that its permanent power characteristics make its torque variation still can keep it to put the paper resistance, makes the rewinding process reach permanent linear speed, the requirement of permanent tension force.

Pressure roller 11 of the present utility model, by HYDRAULIC CONTROL SYSTEM oil cylinder 12, can effectively regulate variation platen pressure in whole rewinding process, can be with some depress power greatly when the little deadweight of rewinding initial stage paper roll is also light, the thick deadweight of paper roll reduces pressure roller 11 when increasing and depresses power, make the tension force that curls obtain balance, making the inside and outside degree of tightness of paper roll consistent is design feature of the present utility model.

When the rewinding reel diameter reaches regulation, close down

motor

14,15; Lift swing arm 11, splicing car 16 is turned to the splicing position, start and to unload paper bowl 13 and paper roll is released from the centre of two bottom rollers 9 unloaded on the paper car 13, will unload the upset of paper car again paper roll is placed on ground, so far finish the complete work period of rewinding.
