Background technology
The paper device that rises is a kind of carving machine that is widely used in, graph plotter, and ink jet printer, mould cutting machine, printer, the needs that the equipment such as machine is cut in spray are a kind of device of web-like paper roll on S. A. fixedly.The paper device kind that rises principle is a lot, but practical function is different with economy.For example: 1, adopt air-expanding shaft to fix, although good fixing effect is stable, need source of the gas, the processing trouble, cost is high.2, adopt mechanical expanding shaft to fix, utilize theory of machines, do not need source of the gas, but complicated in mechanical structure, processed complex, cost is high.3, adopt the tapering object to insert the paper roll two ends, be screwed with S. A. on, although cost is low, but owing to inserting paper roll, tapering is partly arranged, can move to two ends through the long-time paper device that rises that rotates, paper roll breaks away from, this taper simultaneously rise the paper device S. A. patchhole diameter can not with the S. A. external diameter always, cause in rotary course beating because of decentraction or the very large torsion rotation of needs paper roll, service life is short, unstable properties.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the paper device that rises of a kind of simple in structure, easy to use, stable performance, long service life is provided.
A kind of paper device that rises, comprise the paper bar that rises, and the described axial two ends of paper bar of rising are arranged with and are plugged in the compound type risen between paper bar and the paper roll gap mechanism of paper that rises; The described compound type mechanism of paper that rises comprises the exterior part fitted with the paper roll inwall, and revolve the inner component that is located in the exterior part cavity and fits with the paper bar outer wall that rises, be evenly equipped with the cell body of offering along bottom insertion end/precession end toward opposite side on the axial wall body of described exterior part and inner component, the axial wall body top of described exterior part and inner component is provided with the spacing handle of boss.
As further improvement in the technical proposal:
In the inwall of described exterior part, offer along its bottom insertion end direction oblique angle platform obliquely; The precession end outer wall of described inner component is provided with the oblique angle gradient suitable with the oblique angle platform.
The oblique angle span of Tai Ji oblique angle, the described oblique angle gradient is the 0-90 degree.
As further improvement in the technical proposal:
The spacing handle outer wall of the boss of described inner component and exterior part is provided with tread plate.
As further improvement in the technical proposal:
On the contact surface of described exterior part and paper roll inwall, and the contact surface of inner component and the paper bar outer wall that rises is provided with the decorative pattern for increasing friction force.
As further improvement in the technical proposal:
Offer chamfering on the bottom insertion end outer wall of described exterior part.
The utility model is simple in structure, easy to use, utilizes and is similar to the propelling of screw and nut principle, and compound type is risen to the mechanism of paper tensioner in the inside of paper roll, and good stability is also more time saving and energy saving during operation.Comfort level and the state stability of the utility model after installation when the design by the oblique angle that matches in the design of exterior part insertion end chamfering, outer inner component and friction decorative pattern has improved operation greatly in addition.

The specific embodiment
Below in conjunction with specific embodiment, the present invention will be further described.Should be understood that following examples are only for the present invention is described but not for limiting the scope of the invention.
Referring to Fig. 1 and Fig. 2, a kind of paper device that rises that the utility model provides, comprise the paper bar 1 that rises, the described axial two ends of paper bar 1 of rising are arranged with and are plugged in the compound type risen between paper bar 1 and the paper roll 3 gaps mechanism of paper 4 that rises, the described compound type mechanism of paper 4 that rises comprises the exterior part 4a fitted with paper roll 3 inwalls, and revolves the inner component 4b that is located in exterior part 4a cavity and fits with paper bar 1 outer wall that rises; Referring to Fig. 3, be evenly equipped with the cell body 5 of offering along bottom insertion end/precession end toward opposite side on the axial wall body of described exterior part 4a and inner component 4b, the axial wall body top of described exterior part 4a and inner component 4b is provided with the spacing handle 6 of boss.
During use, at first exterior part 4a is inserted, until the spacing handle of the boss of exterior part 6 places are close to paper roll 3 ends; Then will with the inner component 4b of the paper bar 1 that rises, screw in exterior part 4a, proficiency fixed outer part 4a, proficiency is rotated the spacing handle 6 of boss of inner component 4b, until screw.In this precession process, principle rotation inner component 4b or exterior part 4a according to screw nut, make the inner component precession.When inner component 4b precession exterior part 4a, exterior part 4a opens, and inner component 4b shrinks, and these cell bodies 5 rise and allow some leeway to contracting.So that exterior part 4a can spread during spreading, inner component 4b can free shrink.The number of cell body 5 is with risen material, and the own material of required contracting tension difference and parts is different and different.
Embodiment 2
The difference of the present embodiment and embodiment 1 is: spacing handle 6 outer walls of the boss of described inner component 4b and exterior part 4a are provided with tread plate 7.
The difference of the present embodiment and embodiment 1 is: referring to Fig. 4 and Fig. 5, on the bottom insertion end outer wall of described exterior part 4a, offer the chamfering 8 that can play directional tagging.
Embodiment 4
The difference of the present embodiment and embodiment 1 is: while rising for making to contract, effect is better, referring to Fig. 4 and Fig. 5, in the inwall of described exterior part 4a, offers along its bottom insertion end direction oblique angle platform 9 obliquely, coordinates stressed spreading in inner component 4b precession process.This angle is different with the expanding force needed because of risen material, angle slightly variant (adjusting between 0-90).
Also be provided with the oblique angle gradient 9a suitable with oblique angle platform 9 on the precession end outer wall of described inner component 4b, the one, conveniently put into exterior part 4a, be better to coordinate exterior part 4a spreading and inner component 4b itself to shrink in addition.This oblique angle gradient can be with external diameter angle difference and the required difference of expanding force and slightly change (between the 0-90 degree, adjusting).
The present embodiment is with the difference of embodiment 1: because inner component 4b contacts with the paper bar 1 that rises, need fixing.In order to increase friction force, adopt anyhow or the lines 10 of other decorative pattern increases friction force, to play better effect.
Because the outside of exterior part 4a contacts with paper roll 3 inwalls, in order to increase friction force, adopt anyhow or the lines 10 of other decorative pattern increases friction force, to play better effect.
