Abstract

The utility model relates to a static-pressure supporting controllable medium-high roller for a self-loading paper making machine, which is a mechanism of papermaking calender equipment. Both ends of a core axle of the mechanism are installed on a spherical bearing, and a roller case sheathed on the core axle is tightly matched with inner bores on both ends of the roller case through external rings of two sliding bearings. By the sliding bearings of both ends of the roller case, the roller case rotates around the core axle, and the flexibility change of a certain subparagraph along the direction of the generatrix of the roller case is controlled by a hydraulic pump station and an electric control stand. An inner ring of each sliding bearing is provided with a slotted hole matched with a flat segment of the core axle, which reserves a gap that can slide up and down between the core axle and the slotted hole which match with each other and makes the moving direction of a top pressure piston parallel to the moving direction of the core axle. The utility model omits a loading system out of the machine, reduces the volume of equipment, cuts the cost, and brings convenience for operation.

Description

Bootstrap loading paper machine hydrostatic support crown controlled roll

The utility model relates to the mechanism on squeezing, the press polish equipment in a kind of papermaking equipment, relates in particular to the hydrostatic support crown controlled roll mechanism of the linear pressure load that self forms between two pressure rollers, belongs to the D21G1/02 class.

At present, in paper industry, the linear pressure load on the papermaking press polish equipment between the adjacent pressure roller is that the pressure roller deadweight forms by mechanical transmission mechanism, hydraulic pressure, pneumatic or dependence.Promptly utilize the comparatively complicated dynamical system of a cover, produce the linear pressure load when realizing work between adjacent two pressure rollers.For example the last patent (patent No. ZL94214601.8) " roll presses for paper industry hydrostatic support crown controlled roll mechanism " in person of Patent Office of the People's Republic of China's announcement just has above-mentioned shortcoming.When not working, adjacent two pressure rollers are thrown off mutually, are called " roll release ".Fig. 1 promptly represents to load or promote to pressure roller by hydraulic pressure or pneumatic means, power cylinder to go up pressure roller and reach " roll release ", and Fig. 2 then represents to realize loading by the power cylinder of bottom, and realizes " roll release " by the deadweight of bottom roller.When pressure roller was used in the press section of paper machine, often the locus was limited, caused difficulty for the layout of equipment.

The purpose of this utility model is at above-mentioned deficiency, designs the outer loading system of a kind of energy omission machine, reduces the volume of equipment integral body, and reduces cost, handled easily.

The purpose of this utility model is achieved in that bootstrap loading paper machine hydrostatic support crown controlled roll mechanism, comprise that its two ends are loaded on the mandrel of self-aligning spherical support, the both ends endoporus tight fit of the outer shroud of sliding bearing and roller shell, and the sliding bearing by roller shell two ends, the roller shell is rotated around mandrel, on the I shape section mandrel cross section, the several holes that vertical arrangement is arranged facing to compressive region, it forms high-voltage oil cavity with roof pressure piston that is mounted in it and seal, pressure oil is by mandrel side oilhole and oil pipe, grouping is to roof pressure piston small end high-voltage oil cavity fuel feeding, big end curved surface of roof pressure piston and roller shell endoporus match, the control that changes along roller shell generatrix direction segment amount of deflection is hydraulic power unit and electrical control panel, be characterized in: it is that the center is symmetrically distributed that the interior ring of sliding bearing has with its axis, it is up and down circular arc, about be flat horizontal surface impaled abreast hollow slotted eye, the circular mandrel that is whittled into parallel flat horizontal surface section with both sides matches, the arc diameter up and down of interior annular space heart slotted eye is cut flat section outside diameter greater than mandrel, make the mandrel and the slotted eye of cooperation leave the gap value that can slide up and down, mandrel is vertically being arranged several holes facing to the pressurized direction, the roof pressure piston of packing into and forming high-voltage oil cavity, it is parallel that piston is cut flat horizontal surface along its axis moving direction and mandrel.

Ring also can be hanked in the described sliding bearing, and special-purpose rolling bearing is interior to be encircled.

Because adopt present design, there is following advantage in the utility model bootstrap loading paper machine hydrostatic support crown controlled roll mechanism: kept the technical characterictic of hydrostatic support crown controlled roll mechanism, but improved the deficiency of original design; Because the utility model, need not be equipped with controlled in loading system beyond the high rod, produce linear pressure load between the adjacent pressure roller by self structure, can produce linear pressure and " roll release " between the adjacent pressure roller automatically, so just saved the charger of peripheral hardware, simplify the structure, handled easily has greater flexibility.

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 1 is in the correlation technique, makes the schematic diagram of power cylinder to the pressure roller loading by hydraulic pressure or pneumatic means

Fig. 2 is in the correlation technique, realizes loading by the base pressure cylinder, and deadweight realizes the schematic diagram of " roll release " by bottom roller

Fig. 3 be the utility model bootstrap loading paper machine hydrostatic support controlled in " high roller " schematic diagram

Fig. 4 is the cross sectional representation (the A-A cross section of Fig. 3) of the utility model mandrel " I shape " section

Fig. 5 is the cross sectional representation (the B-B cross section of Fig. 3) of the utility model mandrel " both sides are whittled into parallel plane " section.

As shown in Figure 1, 2, hydraulic pressure or pneumatic means 1 load last pressure roller 3 or lower compression roller 4 by power cylinder 2 in the utility model correlation technique, and above-mentioned situation is often limited because of the locus, causes difficulty to apparatus arrangement.

Fig. 3, Fig. 4, Fig. 5 have described the utility model bootstrap loading paper machine hydrostatic support crown controlled roll, it is the mechanism on the press polish equipment, and mandrel 7 is installed on two self-aligning spherical supports 5, and is and for example shown in Figure 5, roller shell 6 is by sliding bearing outer shroud 9 during work, and bearing inner ring 10 rotates around mandrel.Because it is that the center is symmetrically distributed that bearing inner ring 10 has with its axis, it is up and down circular arc, about be flat horizontal surface impaled abreast hollow slotted eye, and mandrel 7 is whittled into parallel flat horizontal surface with its both sides of part that bearing inner ring 10 matches, the arc diameter up and down of the hollow slotted eye of interior ring 10 is cut flat section outside diameter greater than mandrel, make the mandrel slotted eye after the cooperation leave the gap value that can slide up and down, Fig. 3, shown in Figure 4, mandrel 7 in the I shape section faces toward the compressive region direction, vertically arranging several holes, the roof pressure piston 8 of packing into and forming high-voltage oil cavity, it is parallel that piston is cut flat horizontal surface along its axis moving direction and mandrel.

Roof pressure piston 8 and seal form high-voltage oil cavity, pressure oil is by mandrel 7 side oil pipes 11 shown in Figure 4, grouping is the high-voltage oil cavity fuel feeding to the piston small end to the top, big end curved surface of roof pressure piston and roller shell endoporus match, and the control that changes along roller shell generatrix direction segment amount of deflection is hydraulic power unit 12 and electrical control panel 13.
