Abstract
The utility model discloses a kind of core pipe, its drip irrigation device is a kind of core pipe, comprise body, described body is axially arranged with a groove along it, described groove has a vertical plane and a bottom surface, described bottom surface is connected with the outer surface smoother of described body, is provided with layers of two-sided in described groove, and the upper surface of described layers of two-sided flushes with the outside face of described body.The utility model solves when being rolled onto first on core pipe by material, can be pretty troublesome; And the material be wound on core pipe can produce the problem of obvious folding line.
Description
Technical field
The utility model relates to a kind of tubing, and in particular, it relates to a kind of core pipe.
Background technology
Core pipe is the parts for band-type product such as curling various film, adhesive tape or paper, to play the effect of conveniently depositing product and transporting.
The material of core pipe is different, according to the difference of wanted curling product, comprises papery core pipe, plastics core pipe and metal core pipe etc.Plastics core Guan Yiqi is lightweight, smooth surface, the advantage such as wear-resistant, not yielding are widely used.
In prior art, because the surface of core pipe is comparatively smooth, so when material is rolled onto on core pipe first, can be pretty troublesome.Presently used core Guan Jun is the hollow circular-tube of surface smoothing, when curling material has certain thickness, fin together with producing with the contact position in core pipe face at the initiating terminal of material, this road fin can make the curling of next circle of material also produce projection, when material is all wound on after on core barrel, because the pressure be wound around is larger, the material that initial a few circle reels can produce obvious folding line, this requires higher membraneous material for some surface smoothnesses, such as blooming etc. just create impact, for ensureing the performance of product, often on initial a few circle, tool material creasy is just rejected, add the use cost of user, resource be also result in and greatly waste.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of material coiling can will can not produce the core pipe of folding line easily.
For achieving the above object, the utility model provides following technical scheme: a kind of core pipe, comprise body, described body is axially arranged with a groove along it, described groove has a vertical plane and a bottom surface, described bottom surface is connected with the outer surface smoother of described body, is provided with layers of two-sided in described groove, and the upper surface of described layers of two-sided flushes with the outside face of described body.
Preferably, described outer surface of tube body is provided with radiation protective layer.
Preferably, described radiation protective layer is polymer graphite granulosa.
Preferably, described radiation protective layer comprises ceramic fiber layer, natural fiber layer and aramid fiber layer from inside to outside successively.
Preferably, described outer surface of tube body is provided with wearing layer.
Preferably, described wearing layer is acrylic resin rete.
The utility model has following advantage: layers of two-sided be arranged in the groove of outer surface of tube body, when being rolled onto on body first by material, only need be bonded in layers of two-sided by material, easily.In addition, material also can not produce folding line on body.Secondly, the outer surface smoother of the bottom of groove with described body is connected, and the upper surface of layers of two-sided flushes with the outside face of body, make layers of two-sided is arranged in groove more convenient, and also can be more prone to when material is rolled onto on body first paste.Wherein, the radiation protective layer that outer surface of tube body is provided with can protective material not raying, avoids producing some ionization traces, affects the quality of material.Moreover the wearing layer that outer surface of tube body is provided with adds the friction force between material and body, material can be fitted on body more closely, and this wearing layer also extend the service life of body.

Detailed description of the invention
With reference to shown in accompanying drawing, the utility model is further illustrated.
Embodiment one: a kind of core pipe, comprises body 1, body 1 is axially arranged with a groove 2 along it, is provided with layers of two-sided 3 in groove 2.Wherein, groove 2 has vertical plane 21 and a bottom surface 22, and bottom surface 22 is connected with the outer surface smoother of body 1, and the upper surface of layers of two-sided 3 flushes with the outside face of body 1.The outside face of such body 1 defines again a complete periphery due to the layers of two-sided 3 arranged, owing to adding layers of two-sided 3, so, when material is rolled onto on body 1 first, only material need be bonded in layers of two-sided 3, easily.In addition, material also can not produce folding line on body 1.The outer surface smoother of the bottom of groove 2 with described body 1 is connected, and the upper surface of layers of two-sided 3 flushes with the outside face of body 1, make layers of two-sided 3 is arranged in groove 2 more convenient, and also can be more prone to when material is rolled onto on body 1 first paste.
Secondly, body 1 outside face is provided with radiation protective layer 4, and radiation protective layer 4 is preferably as polymer graphite granulosa.Or radiation protective layer 4 is made up of successively ceramic fiber layer, aramid fiber layer and natural fiber layer, ceramic-fibre can radiation proof, reduce the radiation to material, natural fiber can effectively improve its flexibility, and polyamide fibre ensure that the resistance to abrasion of body 1.For strengthening radiation-proof effect, also applying one deck Nano Silver on radiating layer surface, effectively shielding electromagnetic wave.Ceramic fiber layer is composited by radioresistance pottery and epoxy resin, has radiation resistance; Natural fiber layer flexibility is good; The resistance to abrasion of aramid fiber layer is high; Ceramic fiber layer and natural fiber layer are formed jointly the composite fibre layer closely interweaved, this fibrage has the features such as high radiation preventing, flexibility are good, has high-wearing feature simultaneously.
Moreover body 1 outside face is provided with acrylic resin rete or carbide layers, adds the friction force between material and body 1, material can be fitted on body 1 more closely, and this wearing layer 5 also extend the service life of body 1.
Embodiment two: the difference of the present embodiment and embodiment one is, the groove 2 in the present embodiment is two, and is symmetricly set on the outer circumference surface of body 1.In embodiment one, owing to being only just provided with groove 2 towards a tangential direction of body 1, so only towards when the direction of correspondence turning to of body 1, the winding of membraneous material could be realized, when staff is because of carelessness by time anti-loaded for body 1, because core pipe can only rotate facing one direction, so just need again body 1 to be disassembled, change to the winding that membraneous material just can be carried out in correct direction, extremely bother.
And in the present embodiment, owing to being provided with two grooves 2, that rotate forward regardless of core roller like this or counter-rotational, when not needing dismounting core pipe, also can realize the winding of membraneous material and ensureing can not produce projection in the process of winding.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
