Abstract
The utility model relates to a topstitched spiral paper tube, which comprises a paper tube body which is manufactured by spiraling paper. The topstitched spiral paper tube is characterized in that two edges of the paper are respectively provided with grooves; when the paper tube body is wound, the adjacent grooves at the two edges of the paper are butted to form linear topstitching. As the topstitched spiral paper tube adopts the technical scheme, when the paper tube body is wound, the two edges of the paper are designed into a groove shape so that the two adjacent paper edges are mutually overlapped together, the paper edges are pressed by spiral paper tube producing equipment to form linear topstitching almost without gaps, and therefore the quality of the spiral paper tube is greatly increased. Therefore, the indentation of multiple layers of thin films coiled at the outer surface of the spiral paper tube is eliminated, and the waste of the thin films caused by the indentation is reduced.
Description
Technical field
The utility model belongs to paper tube manufacturing technology field, particularly relates to a kind of signature seam spiral paper tube.
Background technology
As everyone knows; Produce and transportation for the ease of the film series products; Generally with film furl on the paper tube; Therefore paper tube is important component part in the film production, and the quality of paper tube quality will directly influence the quality after the film take-up, and is therefore all higher than requirement of products such as industrial coil paper, batching for the structure design and the technical parameter of film class paper tube.For satisfying the various market demands, on the market many paper tubes are disclosed now, for example a kind of spiral paper tube, spiral paper tube are a kind of paper tubes of producing through spiral paper tube production facilities through wide paper, can carry out intercepting according to actual needs after this paper tube moulding.Spiral paper tube one of them technical parameter when actual production is exactly the size of spiral slit; It is to be not more than 1.5mm that international standard has certain regulation to spiral slit; If spiral slit is excessive, the not impression of equal thickness will appear in many layer films of the paper tube outside face that twines so, and the appearance of this impression will directly influence the use of film; Even film do not have use value, and then causes the part waste.Therefore how solving spiral slit is to produce a key problem in technology high-quality, high quality spiral paper tube.
Summary of the invention
The utility model provides a kind of signature simple in structure, easy to make, that reduce spiral slit, the waste of minimizing film to stitch the spiral paper tube for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
A kind of signature seam spiral paper tube comprises the paper tube body that is made by the paper spiral, and it is characterized in that: the both sides of said paper are respectively equipped with groove, and are said when coiling paper tube body, and the adjacent groove butt joint in said paper both sides forms the linear seam of giving as security.
The utility model can also adopt following technical measures:
The inwall both ends of said paper tube body are coated with the wearing layer that prevents the paper end respectively.
The length of said wearing layer is from the inside 30mm～100mm of paper tube body end face.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme; Promptly when coiling paper tube body; The groove shape is processed on the both sides of paper; Just overlap each other at two adjacent paper edges like this, and give as security seam, thereby improved the quality of spiral paper tube greatly through forming the linearity that does not almost have the slit after the compacting of spiral paper tube production facilities; Thereby the impression of avoiding being coiled in many layer films of such spiral paper tube outside face disappears, and has reduced the film that causes owing to impression and has wasted.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is adjacent paper overlap joint structure for amplifying scheme drawing.
Among the figure: 1, paper tube body; 1-1, groove; 1-2, the linear seam of giving as security; 2, wearing layer.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1 and Fig. 2, a kind of signature seam spiral paper tube comprises the paper tube body 1 that is made by the paper spiral, and the both sides of said paper are respectively equipped with groove 1-1, and are said when coiling paper tube body, and the adjacent groove 1-1 butt joint in said paper both sides forms the linear seam 1-2 that gives as security.
When coiling paper tube body, the groove shape is processed on the both sides of paper, just overlap each other at two adjacent paper edges like this; And through forming the linearity signature seam that does not almost have the slit after the compacting of spiral paper tube production facilities; This slit is generally less than 1mm, meets the requirement of international standard far away, and then has improved the quality of spiral paper tube greatly; Thereby the impression of avoiding being coiled in many layer films of such spiral paper tube outside face disappears, and has reduced the film that causes owing to impression and has wasted.
The inwall both ends of said paper tube body are coated with the wearing layer 2 that prevents the paper end respectively.The material of wearing layer 2 can be chosen according to actual needs, both can choose glue, also can select hydrophilic resin etc. for use, reaches wear-resisting effect through PROCESS FOR TREATMENT as long as form wearing layer.
In the said structure, the length of said wearing layer was difficult for factory or too short, the long raw material of having wasted, and too short words do not have optimum efficiency, and the length of general wearing layer is from the inside 30mm～100mm of paper tube body end face.
Like this when long-time the use; Having increased paper tube end inwall and rotating shaft or dop fits; And effectively prevented to produce paper end phenomenon because of friction with rotating shaft or dop; Thereby solved film and when pad pasting prints, produced bubble or fuzzy problem, improved the product design of pad pasting because of what static adsorbed that the paper end causes, reduced pad pasting waste, reduced cost.
The above is merely the preferable example of executing of the utility model, is not the practical range that is used for limiting the utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all fall into the technical scope of the utility model.
