Abstract
A gas-expansion shaft sleeve is sleeved on a gas-expansion shaft for unwinding and winding of a bobbin paper rewinder to fix centers of bobbin papers. The gas-expansion shaft sleeve is cylindrical, asleeve hole is arranged in the middle of the cylindrical gas-expansion shaft sleeve, an axial groove is processed on the surface of the cylindrical gas-expansion shaft sleeve, the gas-expansion shaftsleeve is formed by axially assembling circular-arc-shaped tiles, a groove is processed on an inner circle of each tile, a radial groove is processed at positions of an axial front end and an axial rear end of each tile, a tension spring is disposed inside each groove, the tension springs draw the separated tiles together to form the shaft sleeve, the shaft sleeve is sleeved on the gas-expansion shaft, when the gas-expansion shaft works, the separable tiles on the shaft sleeve are ejected outwardly to lock the centers of the bobbin papers, when the gas-expansion stops, the tension springs on the shaft sleeve draw the separable tiles together to realize separation of the shaft sleeve and the centers of the bobbin papers. The shaft sleeve can be used for various bobbin papers with differentcenter apertures.
Description
Technical field
The utility model belongs to the parts technical field in the printing machinery, relates to the inflatable axle sleeve that uses on a kind of reel paper rewinder let off roll or the wind-up roll.
Technical background
In the prior art, the retractable winding up roller of rewinder adopts inflatable axle construction usually, is convenient to lock the core of reel paper.Yet the diameter of inflatable axle is fixed, and when on axle the reel paper in different cores aperture being installed, the inflatable axle can't the big reel paper of constant aperture owing to the restriction that is subjected to diameter.
Summary of the invention
For solving problems of the prior art, the utility model provides a kind of inflatable axle sleeve, is sleeved on the inflatable axle, to adapt to the reel paper in various different cores aperture.The technical scheme of inflatable axle sleeve is: a kind of inflatable axle sleeve, be used to be sleeved on the let off roll or the wind-up roll of reel paper rewinder, the fixing core of reel paper, the inflatable axle sleeve is cylindrical, there is trepanning cylindrical centre, be processed with axial groove on the cylindrical surface, the inflatable axle sleeve by the tile of circular arc axially assembled, the tile that is used for assembly unit is no less than two, on the outside face of the termination, axial rear and front end of tile, be processed with together groove radially, an extension spring is installed in the groove, extension spring is drawn the tile that separates over to one's side and is formed an axle sleeve together.
After adopting technique scheme, size according to reel paper disc heart aperture, select the inflatable axle sleeve of respective diameters for use, be sleeved on the inflatable axle, when the inflatable axle is worked, the outside jack-up of separable tile on the axle sleeve, the core of locking reel paper, when the inflatable axle quit work, the tile of respectively separating of axle sleeve was drawn in the extension spring on the axle sleeve over to one's side, and the realization axle sleeve separates with the reel paper disc heart.
For convenient and practical, the circular arc tile design of forming axle sleeve can be become three, on the interior circle of every tile, be processed with a groove.
Description of drawings
Fig. 1 is the structural representation of the utility model master apparent direction;
Fig. 2 is the structural representation that the utility model is overlooked direction;
The specific embodiment
Embodiment: as depicted in figs. 1 and 2, a kind of inflatable axle sleeve, be specially adapted to be sleeved on the let off roll or wind-up roll of reel paper rewinder, the fixing core of reel paper, the inflatable axle sleeve is cylindrical, there is trepanning cylindrical centre, be processed with axial groove 3 on the cylindrical surface, axially assembled, the tile 4 that is used for assembly unit has three to the inflatable axle sleeve, is processed with a groove 5 on the interior circle of every tile 4 by the tile 4 of circular arc, at the termination, axial rear and front end of tile 4 outer surface position, be processed with together groove 2 radially, an extension spring 1 is installed in the groove 2, extension spring 1 can be drawn the tile 4 that separates over to one's side and be formed an axle sleeve together.
