Abstract
The invention discloses a tube core with a groove. The tube core comprises a tube core body, and the tube core body is in a hollow cylindrical shape; and an open groove is further formed in the outer surface of the tube core body, and the groove is parallel to the central line of a cylinder. The groove is formed in the outer surface of the tube core body, and materials of a starting portion for material winding can be buried in the groove; and the height difference can be effectively avoided, and the wound materials can be more smoothly wound, the material surfaces are more flat, and material losses can be effectively reduced. The groove formed in the tube core with the groove can remove the height difference, and can be used for protecting a film and winding of a rubber belt, and the tube core is more suitable for winding of thick and hard flexible materials and optic high value-added thin film materials and solves the problems of folds, losses and the like caused by the height difference.
Description
Technical field
The present invention relates to a kind of tube core, particularly relate to a kind of tube core of the band groove for rolling flexible material.
Background technology
Plastic extrusion PP, PE, PVC, the plastic wick such as ABS, be mainly used in PE, PET, PVC, CPP, BOPP, the rolling tube core of the flexible materials such as PI is used, tube core outside face of the prior art is smooth, refer to accompanying drawing 1, there is following shortcoming: because material itself has certain thickness, from rolling, the place of material and die contact creates diff-H, along with the rolling of material, this diff-H continues plurality of layers always, due to the effect of stress, involute 20-30M, the more thin softer rice number of material even can reach 30-50M, surface is caused to have impression, particularly partially hard material, affect quality of materials, or cause material to use.
Summary of the invention
For overcoming the deficiencies in the prior art, the object of the present invention is to provide a kind of tube core of the band groove for rolling flexible material, being intended to improve the quality in soft material wrapup procedure, reducing spillage of material.
For achieving the above object, the present invention is achieved through the following technical solutions:
With a tube core for groove, comprising:
Tube core body, it is the cylindrical shape of hollow, and the outside face of described tube core body is also provided with an open recess, described groove and described its center line parallel.
Preferably, the tube core of described band groove, wherein, described tube core body is the one in PP, PE, PVC, ABS tube core.
Preferably, the tube core of described band groove, wherein, the section shape of described groove is an angular aperture.
Preferably, the tube core of described band groove, wherein, the angle of described angular aperture is 45-170 °.
Preferably, the tube core of described band groove, wherein, the angle of described angular aperture is 45-90 °.
Preferably, the tube core of described band groove, wherein, the degree of depth of described groove is 1-3mm.
Preferably, the tube core of described band groove, wherein, the width of described angular aperture the widest part is 3-8mm.
Preferably, the tube core of described band groove, wherein, the width of described angular aperture the widest part is 5mm.
Beneficial effect of the present invention: the outside face of tube core body is provided with a groove, can be embedded in groove by the material of the start-up portion of rolling material, effectively avoid the problem of diff-H, the material wound of receipts is more smooth-going, material surface is more smooth, effectively reduces spillage of material.
Accompanying drawing explanation
Fig. 1 is the tube core structure schematic diagram of the prior art described in background technology of the present invention;
Tube core structure schematic diagram in the tube core that Fig. 2 is the band groove described in one embodiment of the invention.
Wherein, 1-tube core body, 2-open recess, 3-angular aperture, the 4-opening degree of depth.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail, can implement according to this with reference to specification sheets word to make those skilled in the art.
With a tube core for groove, refer to accompanying drawing 2, comprising:
Tube core body 1, it is the cylindrical shape of hollow, and the outside face of described tube core body is also provided with an open recess 2, described groove and described its center line parallel.The outside face of tube core body is provided with a groove, and can be embedded in groove by the material of the start-up portion of rolling material, effectively avoid the problem of diff-H, the material wound of receipts is more smooth-going, and material surface is more smooth, effectively reduces spillage of material.The groove that the tube core of this band groove carries can eliminate diff-H, can be used for the rolling of preservative film, is more suitable for the rolling of slightly thick, the harder flexible material of material, avoid the folding line that diff-H brings, the problems such as loss.
Further, described tube core body is the one in PP, PE, PVC, ABS tube core.
Further, the section shape of described groove is an angular aperture 3.
Further, the angle of described angular aperture is 45-170 °, when the angle of angular aperture is 45-90 °, this angular aperture section is by the section circle diameter place straight line of described tube core body and be the rectilinear(-al) of 45-90 ° with diameter angle, the thickness of described tube core body is 3-10mm, when the angle of angular aperture is 90-170 °, angular aperture is an opening 90-170 ° fan-shaped.
Further, the angle of described angular aperture is 45-90 °.
Further, the degree of depth of described groove is 1-3mm.
Further, the width 4 of described angular aperture the widest part is 3-8mm.
Further, the width of described angular aperture the widest part is 5mm.
Although embodiment of the present invention are open as above, but it is not restricted to listed in specification sheets and embodiment utilization, it can be applied to various applicable the field of the invention completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the present invention is not limited to specific details and illustrates here and the legend described.
