A kind of coiling tube that is used for leather or textiles
Technical field
The present invention relates to technical field of textile machine, particularly relate to a kind of coiling tube that is used for leather or textiles.
Background technology
In the prior art; The coiling tube that is used for leather or textiles is to the rewinding of curling of the wide cut raw MAT'L of processing, and mostly the structure of its coiling tube is an enclosed pipe, in the coiled strip process; The starting end of its raw material is behind coiling tube one circle; The thickness of the starting end of its raw material can to the raw material of second circle or or even the raw material of the 3rd circle cause impression, or occur second circle raw material or or even the 3rd circle raw material the protrusion phenomenon is arranged and causes problem such as fold at the starting end of its raw material, as shown in Figure 1.And this impression or fold are difficult for reverting to smooth seamless raw material, so cause the raw material of first lap, second circle or even the 3rd circle all can't use, adding up to the raw material that reaches about a meter can only handle as leftover pieces, has increased productive costs; Mostly the material of existing in addition coiling tube is papery, after using once, just does recycling, can not repeated usage, also increased productive costs.
Summary of the invention
The technical matters that the present invention mainly solves provides a kind of coiling tube that is used for leather or textiles, and wrinkle and impression in the time of can reducing coiling tube and begin coiled strip reduce production costs.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of coiling tube that is used for leather or textiles is provided; Comprise: material tube body, open slot, buffer zone, curled portion and chamfering, said curled portion cross section is an open type circular arc, said open slot axially runs through and expects on the arbitrary circular arc wall of tube body; Said open slot comprises the first side wall and second sidewall; The height of said the first side wall is greater than the height of second sidewall, and said buffer zone comprises first circular arc and second circular arc, carries out transition through chamfering between said second sidewall and first circular arc and connects; First circular arc of said buffer zone is connected with curled portion one end transition through second circular arc, and the said curled portion other end is connected with the first side wall of open slot.
In preferred embodiment of the present invention, smooth and easy more seamless in curling rewinding process for making coiling tube, be provided with three-arc between the first side wall of the said curled portion other end and open slot.
In preferred embodiment of the present invention, for the processing technology that makes the material tube body is simpler, said open slot, buffer zone, curled portion, chamfering and three-arc are structure as a whole.
In preferred embodiment of the present invention, can reuse for making coiling tube, conveniently transport not frangible or damage, the material of said material tube body is plastic material, aluminium or steel.
The invention has the beneficial effects as follows: the present invention is optimized design to the coiling tube structure; Increase fluting, buffer zone, chamfering and circular arc; After the raw material starting end inserts in the fluting, even can not produce impression and fold phenomenon around expecting that tube body one circle or two circle backs are reduced again, expect that in addition tube body employing plastic material, aluminium or steel can recycle; Promptly practiced thrift cost, operated also convenient.

The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 2, Fig. 3 and Fig. 4; The embodiment of the invention comprises: a kind of coiling tube that is used for leather or textiles; Comprise: material tube body 1, open slot 2, buffer zone 3, curled portion 4 and chamfering 5, curled portion 4 cross sections are an open type circular arc, open slot 2 axially runs through and expects on the arbitrary circular arc wall of tube body 1; Open slot 2 comprises the first side wall 21 and second sidewall 22; The height of the first side wall 21 is greater than the height of second sidewall 22, and buffer zone 3 comprises that carrying out transition through chamfering 5 between first circular arc 31 and second circular arc, 32, the second sidewalls 22 and first circular arc 31 connects; First circular arc 31 of buffer zone 3 is connected with curled portion 4 one end transition through second circular arc 32, and curled portion 4 other ends are connected with the first side wall 21 of open slot 2.
Further, be provided with a three-arc 6 between the first side wall 21 of said curled portion 4 other ends and open slot 2, make coiling tube smooth and easy more seamless in curling rewinding process.
In addition; Open slot 2, buffer zone 3, curled portion 4, chamfering 5 and three-arc 6 that the present invention is used for the coiling tube of leather or textiles are structure as a whole; And open slot 2, buffer zone 3, curled portion 4, chamfering 5 and three-arc 6 are opened in respectively on the material tube body 1; And the material of material tube body is plastic material, aluminium or steel, or wooden other materials that waits, and processing technology is simple and can recycle the saving cost.
See also Fig. 4 and Fig. 5, the coiling tube that the present invention is used for leather or textiles in use, at first the starting end with wide cut raw material 7 inserts in the open slot 2; Actv. is hidden in the raw material starting end in the open slot, and the back wide cut raw material that begins to curl is tightly fitted and walked around the first side wall 21, chamfering 5, buffer zone 3 and reeling end 4, after the wide cut raw material is walked around a circle; Then when second circle, this moment, starting end did not cause impression, smooth and easy walking around to second circle; Curl successively behind many circles, the raw material of whole volume finished product leather or textiles fully uses, and too much leftover pieces can not occur; And after a volume raw material used up, coiling tube can also be proceeded the curling feed of next group, had promptly saved leftover pieces and had made the coiling tube recycling again; Reduced productive costs, and operation is also very convenient.
The coiling tube that the present invention is used for leather or textiles is different from prior art: replaced the impression that existing enclosed coiling tube occurs in the coiled strip process; And coiling tube can only be carried out disposable drawback; The present invention is used for the coiling tube of leather or textiles under the situation that does not increase any parts; Coiling tube is made further optimal design; Make the difference formation section difference of the height of the first side wall and second sidewall remedy the impression that raw material starting end thickness causes the second circle raw material, buffer zone also is that slick and sly more being crimped onto of raw material expects that on the tube body, the integrated cost of whole operation reduces a lot in addition.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification sheets of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
