Abstract
The utility model discloses a roll paper and paper core anti-disengagement device which comprises an air expanding shaft provided with roll paper in a sleeved mode. Positions, on the two sides of the roll paper, of the air expanding shaft are respectively provided with a check ring in a sleeved mode, the inner diameter of each check ring is the same as that of a paper core of the roll paper, and the outer diameter of each check ring is larger than the diameter of the paper core. The roll paper and paper core anti-disengagement device has the advantages that the check rings and the paper core are expanded by air at the same time after inflation of the air expanding shaft, the check rings are pressed to the two ends of the roll paper, the check rings tightly press the roll paper and the paper core at the same time, friction between the roll paper and the paper core is increased, and the roll paper and the paper core cannot be disengaged. Each roll of the paper can be printed by extra500-800 finished product pages, the utilization rate of the roll paper is improved, and production cost is reduced.
Description
Technical field
The utility model relates to offset lithography web printing field, especially relates to a kind of paper in reel and refill anti-disengaging device.
Background technology
Paper in reel is to be wrapped in the cylindrical paper roll that a diameter on the straight coil paper core is about 1 meter.When printing, need earlier paper in reel to be through on the inflatable axle, the inflatable axle is inflated back swelling paper web, paper roll is lifted on just can begin on the paper frame to have printed.When paper roll has printed soon, because the pulling force of paper tape breaks away from paper tape and refill tube, cause paper roll to separate with refill, cause the paper roll sideslip normally to print.Because the paper roll sideslip can not use, can only scrap when remaining 2 cm thicks often, cause the waste of paper.
Summary of the invention
The utility model purpose is to provide a kind of paper in reel and refill anti-disengaging device that prevents the paper roll sideslip.
For achieving the above object, the utility model can be taked following technical proposals:
Paper in reel described in the utility model and refill anti-disengaging device comprise the inflatable axle that is set with paper in reel; Be respectively installed with back-up ring at the inflatable axle that is positioned at the paper in reel both sides, the internal diameter of described back-up ring is identical with the internal diameter of paper in reel refill, and the external diameter of back-up ring is greater than the diameter of refill.
The utility model advantage is inflatable axle inflation back back-up ring and refill swelling simultaneously, and back-up ring is pressed in the paper in reel two ends, and back-up ring is just simultaneously tightly pushed down paper roll and refill, has increased friction force between the two, and paper roll and refill just can not thrown off like this.Every coil paper can print 500-800 more and open the finished product page, has improved the degree of utilization of reel paper, has reduced productive costs.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is block diagram of the present utility model.
The specific embodiment
As shown in Figure 1, 2, paper in reel described in the utility model and refill anti-disengaging device comprise the inflatable axle 2 that is set with paper in reel 1; Be respectively installed with back-up ring 3 at the inflatable axle 2 that is positioned at paper in reel 1 both sides, the internal diameter of described back-up ring 3 is identical with the internal diameter of paper in reel 1 refill, and the external diameter of back-up ring 3 is greater than the diameter of refill.
Claims (1)
