Abstract

The utility model discloses a monofil yarn cop, which relates to a yarn cop for the monofil to spool into a yarn carrier. Both ends of the yarn tube body are formed into a circular arc surface horn body, and the end face is a tiny-cambered flange. In addition, a middle tube which has a circular arch profile with a middle height and the two sides gently low down is connected between two horn bodies. The boundary among the flange and the horn body, and the flange and the middle tube forms a round corner. The utility model is characterized in that the resistance of the yarn output can be reduced to prevent the yarn cutting phenomenon through the yarn cop with the structure, and the compression strength of the yarn cop body can be increased to extend the service life of the yarn cop, and the function of the multi-direction yarn output can be reached.

Description

Monifilament spool

Technical field

The utility model is a kind of for the spool that twines monofilament, and it is horn-like to provide two ends to form cambered surface, and in the middle of be the arc arch shape pipe, can reach whereby increases the body pressure resistance and avoids the spool distortion, but reaches the purpose of any direction yarn.

Background technology

Yarn has the branch of list, multifilament because of its weave, because the physical structure difference of two kinds of silk materials, so difference is also arranged in the processing of wrapping wire rolling, be difficult for restriction mutually behind the coiling between its silk and the silk as monofilament, normal yarn split the phenomenon of silk (volume) that takes place, so be generally the spool that two ends have flange as the spool of spooling car silk, as wheel pipe (see figure 1) to prevent yarn split the phenomenon of silk (volume).But general multifilament is easier to twine mutually restriction each other, and its quality is softer, so more do not have the situation of doffing with general straight tube spool circumvolution.

The shape of spool except that because of its for list, multifilament different; the shape of spool also can influence the smooth degree and the directivity of yarn in the use; wheel pipe 1 as shown in Figure 1; it no doubt can prevent the phenomenon of doffing with its two end boss 11; but its yarn direction can only be along laterally (direction of arrow among the figure) yarn; owing to Che Si regular meeting forms higher internal pressure and the clamp situation takes place in the 13 place's criss-cross compactings of the right angle of flange 11 and intermediate pipe 12 intersections, so the easiest herein situation that causes broken yarn.

Because wheel pipe 1 has above-mentioned disappearance, so improved spool 2 (see figure 2)s are arranged, it keeps the lower semisection of wheel pipe 1, upper semisection then has an oviduct 21 of upwards carrying out gradually, but this spool 2 also can only be along the last extreme direction yarn that forms oviduct 21, as laterally or from the bottom yarn all being not to be allowed to from the centre, especially horizontal yarn very easily causes the part yarn 22 that is around in oviduct 21 upper ends to produce to fall from the centre collapses the yarn phenomenon, has caused the anxiety that makes the mutual spooling of yarn and break.The intermediate pipe 23 of the spool 2 of this kind improvement and the intermediate pipe 12 of wheel pipe 1 all have the problem of bearing yarn spooling maximum stress, therefore the facts that spool distortion even fracture promptly takes place using after first and second is often arranged, and make the split distortion and be difficult to use of yarn behind the volume yarn.Another problem of this improved spool 2 is identical with wheel pipe 1, promptly remains the right angle state at its flange 24 and intermediate pipe 23 intersections, and causes clamp to cause that regular meeting breaks yarn when wire vent easily.

The utility model content

Existing spool ubiquity spool intensity not good yielding, the yarn direction is single can't multidirectionally select, and situation such as the normal easily broken string in the somewhere of yarn process is for improving these phenomenons, the spool of a kind of improvement of the special proposition of the utility model.The feature of spool is the loudspeaker face of circular arc having a contraposition at the body two ends, and connects the intermediate pipe that is arc arch shape between the two loudspeaker faces.Above-mentioned loudspeaker mask has the characteristics of easy yarn, though this advantage also appears at existing as above-mentioned spool in, two ends of the present utility model loudspeaker face is one circular-arc, compressive strength that also can enhancing place except that the resistance that can reduce yarn.Again, intermediate pipe is that a kind of centre is higher and towards the arch cambered surface of two ends loudspeaker face under gradually, the acting as of its maximum is provided at the coiling yarn split after, the maximum anti-stress intensity of spool, make more not yielding and can be the repeatedly long-term repeated application of spool, this for existing wheel pipe and improved spool can't finish.Moreover, the end of above-mentioned loudspeaker face has the flange of a dimpling, both constitute a fillet at the phase cross surface, in addition, the interface of loudspeaker face and intermediate pipe also has similar fillet design, this fillet has reduced yarn to be taken place at this staggered formed stress of winding and clamp situation, can not cause the broken string phenomenon easily when allowing yarn so far.

In sum, the utility model is reversible exempts from the disappearance that traditional spool causes, and utilizes the utility model can select by its one side yarn of the loudspeaker face at two ends, or by the horizontal yarn at intermediate pipe place, the yarn direction that makes this spool is more than traditional spool.

The specific embodiment

See also Fig. 3, Fig. 4, the two ends of spool 3 of the present utility model are that the intermediate pipe 32 that a kind of loudspeaker face 31, with cambered surface is arc arch shape then is connected between the two loudspeaker faces 31.The outline line up and down of intermediate pipe 32 is that central authorities are high and to the gradually low arch camber line of two loudspeaker faces 31.Again, the end of loudspeaker face 31 has the flange 33 of a dimpling, and the boundary of itself and loudspeaker face 31, and the boundary of intermediate pipe 32 and loudspeaker face 31 all form a fillet 34.Spool 3 as above-mentioned structure, the central higher profile place 321 of its intermediate pipe 32, ability with preferable anti-yarn stress, allow spool unlikely distortion easily after the operation of repeatedly winding yarn, make spool can be concentrically ringed rotation, do not cause the yarn that the is rolled into distortion of splitting and can not produce eccentric rotary in the process of volume yarn.The arc loudspeaker face 31 at two ends can make the resistance force diminishes of yarn, and smooth yarn of energy and minimizing broken yarn situation, its arc loudspeaker face 31 also can provide anti-yarn to twine internal stress certainly, slows down the speed of spool distortion.As for be formed at 34 of fillets that loudspeaker face 31, intermediate pipe 32 and two end boss 33 have a common boundary can avoid because of the broken string of right angle or excessively poly-this winding of the caused yarn of acute angle phenomenon may.

In addition, as shown in Figure 4, the utility model is because of its shape facility, make it can select to draw yarn by one of them loudspeaker face of two ends, or the yarn that causes this spool 3 to be turned to by the horizontal yarn in intermediate pipe 32 places (as the upper and lower and lateral arrows among the figure) splits and can promote it and utilize the space in any direction yarn.

Claims (1)

1, a kind of Monifilament spool is characterized in that, be to have an at both ends to form the horn body of arc surface, and it is high and to the intermediate pipe of the low gradually arc arch shape profile of two horn body directions in the middle of forming to connect two horn bodies; And the end of above-mentioned horn body forms the flange that a dimpling goes out again, and the boundary of flange and horn body, horn body and intermediate pipe constitutes a fillet.
