Abstract
The utility model discloses a pneumatic clamping device for a rotating roller. The pneumatic clamping device comprises a fixed sleeve, a sliding sleeve is mounted in the fixed sleeve, one end of the sliding sleeve is fixedly connected with a sliding seat, an abutting spindle is rotatably connected into the sliding seat, the other end of the sliding sleeve is connected with an abutting device for abutting the abutting spindle, the sliding sleeve is slidably connected with the fixed sleeve, and the sliding seat is slidably connected with the fixed sleeve. When in operation, a cylinder only linearly moves and cannot rotate at a high speed along with the abutting spindle, the abutting spindle rotates at the high speed along with a paper roller to unwind paper, so that the paper roller can be abutted, and rotary unwinding of the paper roller can be realized, and the service life of the cylinder is prolonged.
Description
Technical field
The utility model relates to a kind of apparatus for coating, relates to a kind of rotating roller air clamper specifically, belongs to printing coating technique field.
Background technology
Printing machine mill roll two ends in coating process are spurred paper by motor after need holding out against with the top again, finish the paper process of moving back moving back on the paper machine spider rotation at a high speed.
The mill roll clamping mode is: in the rack-mount fixed cover of air clamper, cylinder piston rod directly is connected on the main shaft of rotation top and rotates with paper bowl.
The shortcoming of this device is: 1, cylinder piston rod with hold out against main shaft and be connected, cylinder piston rod rotates with paper bowl with holding out against main shaft.Frequent because the off-centre of paper bowl causes beating of lifting axe and cylinder piston rod when moving back paper, thereby make cylinder wear, gas leakage, will the mill roll that move back in the paper be dropped because gas leakage causes power transmission shaft to retreat if the cylinder replacing is untimely, smash unreeling stand, cause equipment and personnel's security incident.
2, hold out against cylinder and produce for Germany's this reincarnation of expense, value is high, and delivery cycle is long.Because the eccentric situation of paper bowl ubiquity only is that the frequent breakage of cylinder causes non-programmed halt about 40 days so hold out against the life cycle of cylinder, also be that buying and maintenance have brought great difficulty.
The utility model content
Problem to be solved in the utility model provides a kind of service life that can prolong cylinder, and the paper bowl that is moving back paper (rotation) in stopping to produce drops, the potential safety hazard of elimination personnel and equipment, the rotating roller air clamper of minimizing maintenance cost and buying expenses.
In order to address the above problem, the utility model by the following technical solutions:
A kind of rotating roller air clamper, comprise fixed cover, in the described fixed cover slip cap is installed, a wherein end of described slip cap is fixedly connected with sliding seat, be rotatably connected in the sliding seat and hold out against main shaft, the other end of described slip cap is connected with to hold out against the holding device of main shaft, between described slip cap and the fixed cover, be slidingly connected respectively between sliding seat and the fixed cover.
Below be the utility model for further improvement of these options:
Holding device comprises cylinder, and cylinder is fixed on the fixed cover by gland, and the piston rod of described cylinder is fixedlyed connected with slip cap.
Further improve: the described main shaft that holds out against is by being rotationally connected between bearing and the sliding seat.
During work, cylinder is only done rectilinear motion, not with holding out against the main shaft high-speed rotation.Holding out against main shaft finishes with the paper bowl high-speed rotation and moves back paper.Like this, can finish the holding out against of paper bowl, can realize that again paper is moved back in the rotation of paper bowl, prolong the service life of cylinder.
The utility model adopts such scheme, has the following advantages:
1, security; Cylinder piston rod no longer rotates with paper roll, the wearing and tearing that alleviate sealing ring, and the cylinder seal type is strengthened, and can keep pressure, and piston rod can in use not bounce back, and guarantees the steadiness of paper roll in rotary course.The phenomenon that paper roll in process of production falls can not occur, strengthen the security of personnel's equipment.
2, economical; The annual cylinder that uses of original paper structure form of moving back improves the back according to the life-span of the cylinder of motion mode of the same race greatly about 10, estimates that this cylinder service time can be more than 10 years.
3,, practicality: it is simple in structure that this moves back the paper holding device, is easy to processing, low cost of manufacture; Safeguard and change simple and easy to do.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Among the figure: the 1-slip cap; The 2-fixed cover; The 3-cylinder; 4-holds out against main shaft; The 5-piston rod; The 6-gland; The 7-bearing; The 8-sliding seat.
The specific embodiment
Embodiment, as shown in Figure 1, a kind of rotating roller air clamper, comprise fixed cover 2, in the described fixed cover 2 slip cap 1 is installed, a wherein end of described slip cap 1 is fixedly connected with sliding seat 8, is rotatably connected in the sliding seat 8 and holds out against main shaft 4, and the other end of described slip cap 1 is connected with to hold out against the holding device of main shaft 4.
Between described slip cap 1 and the fixed cover 2, be slidingly connected respectively between sliding seat 8 and the fixed cover 2.
Holding device comprises cylinder 3, and cylinder 3 is fixed on the fixed cover 2 by gland 6, and the piston rod 5 of described cylinder 3 is fixedlyed connected with slip cap 8.
The described main shaft 4 that holds out against is by being rotationally connected between bearing 7 and the sliding seat 8.
Described bearing 7 is two covers, and wherein a cover is thrust ball bearing, and another set of is self-aligning roller bearing.
During work, 3 in cylinder is done rectilinear motion, not with holding out against main shaft 4 high-speed rotation.Holding out against main shaft 4 finishes with the paper bowl high-speed rotation and moves back paper.Like this, can finish the holding out against of paper bowl, can realize that again paper is moved back in the rotation of paper bowl, prolong the service life of cylinder.
