A kind of wear-resisting type paper tube
Technical field
The utility model relates to field of papermaking, particularly relates to a kind of wear-resisting type paper tube.
Background technology
Paper tube is a kind of coil paper inner core during for coil paper, existing paper tube, and it comprises the paper tube body, the surface distribution of paper tube body has salient point.The paper tube of this structure in use, is set in live-rollers with paper tube and carries out coil paper, and in long-term use procedure, the inwall of paper tube easily is worn, and causes paper tube to damage.
In sum,, for the defect of prior art, need especially a kind of wear-resisting type paper tube, thereby solve above-mentioned problem.
Summary of the invention
The utility model, in order to solve the problem of prior art, provides a kind of wear-resisting type paper tube.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of wear-resisting type paper tube, comprise the paper tube body, the paper tube body is provided with salient point, the long 100-150cm of paper tube body, paper tube body wall thickness 1-5cm, the inside of paper tube body is provided with wear-resisting ring, the length of wear-resisting ring and paper tube body equal in length.
In preferred embodiment of the utility model, described wear-resisting ring is rubber ring.
In preferred embodiment of the utility model, the thickness of described wear-resisting ring is 1-2cm.
The beneficial effects of the utility model are: the utility model is simple in structure, designs ingeniously, and such paper tube in use passes wear-resisting ring with live-rollers, so just can not cause the paper tube wearing and tearing.This is a kind of new technical scheme, is convenient to promote.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand,, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of wear-resisting type paper tube described in the utility model, comprise paper tube body 1, paper tube body 1 is provided with salient point 2, the long 100-150cm of paper tube body 1, paper tube body 1 wall thickness 1-5cm, body 1 inside of paper tube is provided with wear-resisting ring 3, the length of wear-resisting ring 3 and paper tube body 1 equal in length.Wear-resisting ring 3 is rubber ring.The thickness of wear-resisting ring 3 is 1-2cm.The utility model is simple in structure, designs ingeniously, and such paper tube in use passes wear-resisting ring with live-rollers, so just can not cause the paper tube wearing and tearing.This is a kind of new technical scheme, is convenient to promote.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification sheets and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
