Preferably, the distance between the central line of the conical wire receiving groove and the tail part of the paper tube body is 7.5-9.5mm, and the tail part of the paper tube body is provided with a chamfer.
Preferably, the depth of the circumferential indentation is 0.2-0.4mm, and the bottom corner of the circumferential indentation is in fillet transition.
Preferably, one or two 1/6 circumferential conical wire receiving grooves are formed on the circumferential indentation.
Preferably, the opening included angle of the conical wire receiving groove is 120 degrees.
Preferably, the width of the opening at the top end of the tapered wire receiving groove is 2.5mm, the width of the opening at the top end of the tapered knife edge is 0.3mm, and the depth of the tapered knife edge is 1.5 mm.
Preferably, the end part of the paper tube body is provided with an inner flanging circular arc structure.
Preferably, the inner flanging circular arc structure is inwards turned for 180 degrees on the paper tube body, and the radius of the inner flanging circular arc structure is 4.6 mm.
Preferably, a layer of parchment paper is arranged on the outer surface of the paper tube body.
Preferably, the paper tube body is formed by winding strip paper, the winding angle is 21-29 degrees, the outer diameter of the paper tube body is 72.4-72.7mm, the inner diameter of the tail part of the paper tube body is 66.4-66.6mm, the inner diameter of the end part of the paper tube body is 54-54.2mm, and the length of the paper tube body is 215.8-216.2 mm.
Compared with the prior art, the utility model following beneficial effect has: the utility model discloses a paper tube intensity is higher, has obviously improved the switching success rate of coiling head, has reduced the waste silk and has produced, has reduced the production consumption when improving production efficiency to improve low reaches customer's production efficiency, reduced the waste of raw materials.

Detailed Description
The technical scheme of the utility model is described in detail in combination with the accompanying drawings, refer to fig. 1 and be the utility model discloses a spinning paper tube structure schematic diagram, spinning paper tube include paper tube body 1, this paper tube body 1's afterbody is equipped with circumference indentation 2, the toper that is equipped with local circumference on the circumference indentation 2 receives the silk groove 3, is equipped with tapering edge of a knife 4 in the toper bottom that receives silk groove 3.
The paper tube body 1 is formed by surrounding strip paper, the surrounding angle is 21-29 degrees, the outer diameter of the paper tube body 1 is 72.4-72.7mm, the inner diameter of the tail part of the paper tube body 1 is 66.4-66.6mm, the inner diameter of the end part of the paper tube body 1 is 54-54.2mm, the length of the paper tube body 1 is 215.8-216.2mm, and the end part of the paper tube body 1 is provided with a chamfer. The width of the circumferential indentation 2 is 5mm, the depth is 0.2-0.4mm, the bottom corner of the circumferential indentation 2 is in fillet transition and is used for preventing the bottom corner from being cracked in the rolling process, and the circumferential indentation 2 is provided with a conical wire receiving groove 3 with a local circumference or two conical wire receiving grooves 3 with local circumferences uniformly distributed. Be equipped with 1/6 circumference toper silk receiving groove 3 on the circumference indentation 2, the opening contained angle that toper silk receiving groove 3 was 120 for prevent that a large amount of monofilaments from twining in the silk receiving groove, be unfavorable for subsequent getting the silk. The width of the opening at the top end of the conical wire receiving groove 3 is 2.5mm, the width of the opening at the top end of the conical knife edge 4 is 0.3mm, and the depth of the conical knife edge is 1.5 mm. The end part of the paper tube body 1 is provided with an inward flanging circular arc structure 5, the inward flanging circular arc structure 5 is inward turned for 180 degrees on the paper tube body 1, and the radius of the inward flanging circular arc structure 5 is 4.6 mm. The outer surface of the paper tube body 1 is provided with a layer of parchment paper for improving the strength of the paper tube.
Firstly, the paper tube for spinning, through make the circumference indentation on paper tube body afterbody and set up toper silk receiving groove in the circumference indentation. When the winding head is switched, the monofilaments can easily slide into the conical filament receiving groove through the circumferential indentation, so that the attachment rate and the switching success rate of the monofilaments are greatly improved; the tapered knife edge additionally arranged on the tapered filament receiving groove can further increase the probability that the monofilament is clamped in the tapered filament receiving groove, and further improve the switching success rate of the winding head.
Secondly, the paper tube for spinning, its terminal surface adopts paper tube body inside flanging circular arc structure, because the inside flanging circular arc structure surface of this end of body of paper tube is smooth, in actual production process, the terminal surface of this kind of paper tube body is difficult for because of damaging the perk, depositing the in-process, the wastepaper problem that the moisture appears need not be considered, and then appear disconnected silk, the broken silk phenomenon when can effectively prevent chemical fiber spinning low reaches customer from backing off, the most probable problem of avoiding downstream customer production efficiency low, the loss is serious.
The foregoing shows and describes the general principles of the present invention, with its principal features and advantages, and further, various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
