Description

Locking type roll paper shaft

Technical Field

The utility model belongs to the technical field of the printing auxiliary assembly and specifically relates to a locking formula roll paper axle is related to.

Background

At present, most of paper used on a printing machine is wound on a hollow winding drum, and then when the paper winding machine is used, a paper winding shaft is inserted into the winding drum wound with the paper, then the paper winding shaft is installed on the printing machine, and the printing machine drives the paper winding shaft to rotate in the printing machine and supplies the paper to the inside of the printing machine.

The existing roll paper shaft comprises an adapting part, a driving end and a mounting end, the cross section of the adapting part is in the shape of a cylindrical rod, the driving end is arranged at one end of the adapting part, the mounting end is arranged at one end, far away from the driving end, of the adapting part and used for mounting the roll paper shaft on a printing machine, and after the roll paper shaft is mounted on the printing machine, the printing machine drives the roll paper shaft to rotate in the printing machine through the driving end and simultaneously supplies paper for the inside of the printing machine.

The above prior art solutions have the following drawbacks: when current roll paper axle used, because need insert the inside of reel with the roll paper axle, so people often can set the radius of accepting part to be less than the reel internal diameter, because the paper weight ratio on the reel is great, so after people use the roll paper axle to mention the reel, the reel can take place to deform under the action of gravity of paper, lead to reel and roll paper axle to take place off-centre, when roll paper axle drives the reel and for the inside paper supply of printing machine like this, the reel can take place to rock in the inside of printing machine, can influence the printing quality of printing machine even.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a locking formula roll paper axle has reached and has avoided the reel to take place to warp, reduces the reel and at the inside range of rocking of printing machine, guarantees the effect of the printing quality of printing machine.

The above technical purpose of the present invention can be achieved by the following technical solutions:

the utility model provides a locking formula roll paper axle, includes the bolster, the radius of bolster is less than the internal diameter of reel, is provided with the locking device who is used for locking the reel on the bolster, and locking device includes that the symmetry sets up two locking rings on the global of bolster, locking ring and bolster threaded connection, and the locking ring external diameter is along getting close to the direction grow gradually that keeps away from each other from each other, and the minimum external diameter of locking ring is less than the reel internal diameter, and the maximum external diameter of locking ring is greater than the reel internal diameter.

By adopting the scheme, before the roll paper shaft is inserted into the winding drum, a worker firstly takes off the locking ring from one end of the roll paper shaft and then inserts the roll paper shaft into the winding drum; after the roll paper shaft is inserted into the winding drum, firstly, rotating a locking ring on a bearing rod, and moving the locking ring on the bearing rod in a direction close to the winding drum until the locking ring is abutted against the winding drum; then another locking ring is arranged on the bearing rod, and the locking ring is driven to move towards the direction close to the winding drum until the two locking rings are simultaneously abutted against the winding drum; then, the worker can rotate the two locking rings simultaneously, because the outer diameters of the locking rings are gradually increased along the direction from the mutual approaching direction to the mutual departing direction, and the radius of one side, close to the winding drum, of the locking ring is minimum, when the two locking rings are driven to move towards the direction close to the winding drum simultaneously, the end faces, close to each other, of the two locking rings enter the inside of the winding drum; because the biggest external diameter of locking ring is greater than the reel internal diameter, so after moving one end distance to two locking rings, the global of two locking rings can with the reel butt to the global has the supporting role to the reel of locking ring, and like this when people take up the reel that has rolled up the paper through the winding shaft, the possibility that the reel takes place to warp will reduce, has reached the effect that reduces the roll and has reduced the range of rocking of reel in the inside printing machine, the printing quality of assurance printing machine.

The utility model discloses further set up to, a plurality of annular anti-skidding grooves have been seted up on the global of locking ring.

Through adopting above-mentioned scheme, the anti-skidding groove on the locking ring global can increase the frictional force between locking ring and the reel, just so can make the process that the stock form axle drove the reel and rotate together more stable.

The utility model discloses further set up to, one side that the locking ring was kept away from each other is provided with and is used for carrying out spacing adjusting device to the locking ring.

By adopting the scheme, after the reel is supported by the two locking rings on the bearing rod, the adjusting device can limit the locking rings because the paper on the reel has larger mass, so that the adjusting device can avoid the locking rings from moving towards the direction away from each other under the action of gravity of the paper on the reel, and finally the reel is deformed.

The utility model discloses further set up to, adjusting device includes the adjustable ring, and the adjustable ring cover is established on accepting the global of pole and with accepting pole threaded connection.

Through adopting above-mentioned scheme, the locking ring props up the reel after, people can rotate the adjusting ring on the adapting rod for two adjustable rings can with two locking rings side looks butt of keeping away from each other, the adjustable ring just can play spacing effect to the locking ring like this.

The utility model discloses further set up to, the radius that the position that the bolster is close to both ends face is less than the radius that is close to bolster central point department of putting.

By adopting the scheme, because the radius of the positions, close to the two end surfaces, of the bearing rod is smaller than the radius of the position, close to the center of the bearing rod, when people need to move the adjusting ring and the locking ring in the mutually-away direction and move to the part, with the smaller radius, of the bearing rod, a worker can directly move the adjusting ring and the locking ring on the circumferential surface of the bearing rod, and therefore the adjusting speed of the adjusting ring and the locking ring is increased.

The utility model discloses further set up to, a plurality of adjustment tanks have evenly been seted up to the global of adjustable ring.

Through adopting above-mentioned scheme, the adjustment tank on the adjustable ring global can make things convenient for people to rotate the adjustable ring.

To sum up, the utility model discloses following technological effect has:

1. by arranging the locking device, after the carrying rod is inserted into the drum, the drum can be supported by the locking device, so that when the drum with paper is driven by the paper winding shaft to move, the possibility of deformation of the drum is reduced, the shaking amplitude of the drum in the printing machine is reduced, and the printing quality of the printing machine is ensured;

2. through having set up adjusting device, behind locking device locking roll web, adjusting device can carry on spacingly to the inside locking ring of locking device, has reached the effect that reduces the possibility that the locking ring takes place to slide on the bolster under the action of gravity of reel and stock form.
