Abstract
The utility model relates to a support core shaft for a paper core in papermaking industry, in particular to a mechanical tapered expansion core shaft comprising a shaft core with a retaining clip, threaded shaft necks are arranged at two ends of the shaft core, locking handles are mounted on the threaded shaft necks, and two tapered expansion cores in opposite directions are sleeved on the shaft core between the locking handles. The mechanical tapered expansion core shaft has the advantages of simple design, convenience in processing, strong practicability, and remarkable effect; and waste caused by the reason that paper rolls can not be used due to extruding deformation of the paper core is greatly reduced.
Description
Technical field
The utility model relates to a kind of paper core support mandrel in the paper industry, specifically is the bloated mandrel of a kind of mechanical type taper.
Background technology
At present, in paper industry, last finished paper generally puts goods on the market with two kinds of forms, and a kind of is paper roll, and another kind is the paper that branch cuts.General its inside of paper roll of spooling of dividing all uses the tubulose refill as support, refill two effects are arranged: the one, make things convenient for batching of paper, the 2nd, make things convenient for the paper debatching.
When the paper debatching, generally with diameter slightly the inflatable axle slightly littler than paper core interior diameter pass paper core, support the paper roll debatching, and the tension force of paper web when giving the paper roll propulsive effort with the debatching of control paper.But paper roll is in actual shipment or in using, paper core is very easy to be extruded distortion, is out of shape serious slightly paper core and can't inserts the inflatable axle, thereby causes a whole coil paper to use, and causes serious waste.
Summary of the invention
The utility model is the technical matters that exists at prior art, and a kind of mechanical type taper mandrel that expands is provided, and can reduce because of refill and be out of shape the waste that causes.
The utility model is realized by following technical measures: a kind of mechanical type taper mandrel that expands, it comprises that having geometrical clamp gets a core, the two ends of described axle core are provided with threaded journal, the clamp handle that matches with it is housed on threaded journal, is set with the bloated core of the relative taper of both direction on the axle core between two clamp handles.
The expand endoporus of core and the central exterior surface of axle core of above-mentioned taper is provided with spline, guarantee taper expand core and the axle core between move and be straight line, make the taper core that expands be more conducive to the tensioning paper core and can not produce slip.
The outside face of the bloated core of above-mentioned taper is provided with skid resistant course, increases the friction force between bloated core of taper and the paper core, prevents to produce skidding between the two.
The beneficial effects of the utility model by technique scheme as can be known, the two ends of described axle core are provided with threaded journal, clamp handle is housed on the threaded journal, be set with the bloated core of the relative taper of both direction on the axle core between two clamp handles, by the sway of clamp handle on threaded journal, make the bloated core of taper of paper core both sides, thereby move the tensioning paper core to the centre.The expand endoporus of core and the central exterior surface of axle core of taper is provided with the guiding spline, guarantee taper expand core and the axle core between move and be straight line, make the taper core that expands be more conducive to the tensioning paper core and can not produce slip.The expand outside face of core of above-mentioned taper is the antiskid surface that spacing convave trough is arranged, and increases expand friction force between core and the paper core of taper, prevents to produce skidding between the two, and this design can be given in addition propulsive effort of paper roll equally, and the tension force of control paper pair.The utility model simplicity of design, easy to process, practical, effect is obvious, greatly reduces paper roll and can't use the waste that causes because of paper core is extruded distortion.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 is the axle core, and 2 is geometrical clamp, and 3 is clamp handle, and 4 are the bloated core of taper, and 5 is paper core, and 6 is spline, and 7 is threaded journal.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, a kind of mechanical type taper mandrel that expands, it comprise have geometrical clamp 2 an axle core 1, the two ends of described axle core 1 are provided with threaded journal 7, be equipped with on the threaded journal 7 and be set with the bloated core 4 of the relative taper of both direction on the axle core 1 between clamp handle 3, two clamp handles 3.The central exterior surface of the endoporus of the bloated core 4 of taper and axle core is provided with guiding spline 6, and the outside face of the bloated core 4 of taper is the antiskid surface that spacing convave trough is arranged.
Using method is that the paper core 5 with the small end insertion of the bloated core 4 of two tapers is out of shape by the sway of clamp handle 3 on threaded journal 7, makes the bloated core 4 of taper of paper core 5 both sides, thereby moves tensioning paper core 5 to the centre.
Claims (3)
1. the mechanical type taper mandrel that expands, it comprises that having geometrical clamp gets a core, it is characterized in that: the two ends of described axle core are provided with threaded journal, and the clamp handle that matches with it is housed on threaded journal, are set with the bloated core of the relative taper of both direction on the axle core between two clamp handles.
2. the mechanical type taper according to claim 1 mandrel that expands is characterized in that: the expand endoporus of core and the central exterior surface of axle core of described taper is provided with spline.
3. the mechanical type taper according to claim 1 and 2 mandrel that expands is characterized in that: the expand outside face skid resistant course of core of described taper.
