Abstract

The utility model relates to a winding bobbin for spinning, in particular to a winding bobbin used during winding heavy-denier industrial filaments. The winding bobbin for the spinning consists of a bobbin body, the circumferential direction of the bobbin body is provided with a catching seam, a through groove is arranged on the catching seam, two end parts of the through groove are connected with the catching seam, and the middle part of the through groove is wider than the two end parts. The winding bobbin has the advantages that: 1, when tail yarns are needed, a knotting knife is inserted into the newly increased through groove to totally cut off the yarns in the through groove, then the cut short yarns are cleared away, and naturally the tail yarns are discharged out, so the tail yarns do not need to be sought, the labor and the time are saved, and the probability of disarranging the tail yarns is greatly reduced; 2, the through groove is equivalent to increasing the width of the catching seam, the success rate of reel alternation switchover cannot be reduced when the length size of a paper tube has a slight error, and the compatibility to the size of the paper tube is better; and 3, the through groove has obvious collecting effect on the redundant tail yarns, and a plurality of rings of tail yarns are not easy to scatter.

Description

A kind of spinning winch spool

Technical field

The utility model relates to the winch spool that spinning is used, the winch spool that uses when relating in particular to the industrial filament coiling and molding that is fit to the thick dawn.

Background technology

The winding filament head that uses is a beautiful chemical fibre equipment Co., Ltd BWA335G type in Beijing at present, and this type uses the paper tube of φ 95/108 length 225mm.Have on the former paper tube one by wide narrow down catch silk seam, catching silk seam length is 3/4 girth of paper tube, the degree of depth 1/2 paper tube wall thickness.When the spinning cake of full volume switched on the new paper tube, the silk device that moves of winding head moved on to the seam place of catching of paper tube with long filament, and long filament embeds the slit and is fixed under the effect of tension force, form the tail yarn of new spinning cake, begins then to reel again.The shortcoming of this former paper tube is: 1, when next procedure need be used the tail yarn joint of spinning cake, because the tail yarn laminates layer by layer catching a seam place, take out relatively difficulty of tail yarn, the time that consumes is long, the kind at especially thick dawn, be very easy to when getting the tail yarn, on the contrary the tail yarn done at random, cause the tail yarn to use.2, when the length dimension of paper tube had error slightly, the change of lap success rate for switching obviously reduced, and causing to produce to consume increases.

Summary of the invention

In order to solve above-mentioned technological deficiency, the purpose of this utility model provides a kind of spinning winch spool, and this winch spool has characteristics simple in structure, easy to use.

In order to realize above-mentioned technical purpose, the utility model has adopted following technical scheme:

A kind of spinning winch spool, this winch spool is made of cylindrical shell, and the end of cylindrical shell is circumferentially with catches silk seam, and the described silk of catching is sewed on and is provided with groove, and two ends of groove are stitched and are connected with catching silk, and the middle part width of groove is greater than two ends.

As preferably, above-mentioned catch circumferential length that the silk seam is provided with greater than 1/2 circumference, the degree of depth is that cylindrical shell wall thickness 1/3～2/3 is thick, a width of catching the silk seam is narrowed down to two ends gradually by the middle part.As preferred again, the above-mentioned circumferential length of catching the setting of silk seam is 3/4 circumference, and the degree of depth is that cylindrical shell wall thickness 1/2 is thick.

As preferably, the inclined-plane of the middle part of above-mentioned groove by both sides is to two end transition.

The utility model is sewed on the increase groove owing to adopted above technical scheme at the former silk of catching, and overcomes the shortcoming of former paper tube.Winch spool of the present utility model has following having a few: when 1, needing the tail yarn, the knotting cutter is inserted in the groove that increases newly, yarn in the groove is all cut off, clean out the shorter yarn that is cut off, the tail yarn has just come out naturally, need not go for the tail yarn again, saving of work and time, and the chance of disarraying the tail yarn significantly reduces.2, groove is equivalent to has increased the width of catching the silk seam, and when the length dimension of paper tube had error slightly, the change of lap success rate for switching can not reduce, better to the compatibility of paper tube size.3, groove has the effect that significantly compiles to unnecessary tailfiber, and the multi-turn tailfiber is difficult for scattering.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is made a detailed explanation.

A kind of spinning winch spool as shown in Figure 1, this winch spool is made of cylindrical shell 1, and the end of cylindrical shell 1 is circumferentially with catches silk seam 2, and the circumferential length of catching 2 settings of silk seam is 3/4 circumference, and the degree of depth is that cylindrical shell 1 wall thickness 1/2 is thick.As shown in Figure 1 and Figure 2, catch silk seam 2 and be provided with groove 3, two ends 5 of groove 3 are stitched 2 and are connected with catching silk, and middle part 4 width of groove 3 are greater than two ends 5, and the inclined-plane by both sides is to two end 5 transition.
