Description

A kind of yarn prevents back twist device

Technical field

The utility model relates to ribbon textile technology fields more particularly to a kind of yarn to prevent back twist device.

Background technique

Twisting is that the process of yarn is formed by rotary motion.For example, single line is made of 24 silks, 24 silks are mutual Winding can just make the more solid exquisiteness of line, routing around the more tight namely twist it is higher, it is just relatively more compact to weave the cloth come, hangs down Feel, fastness is good.Be exactly no routing if not twisting, be not wound around between silk and silk together, cloth cover relaxation, hang down sense it is poor, Fastness is poor.

But in the prior art, yarn grain is mounted on support rod, by pullling yarn, rotates yarn grain around support rod.? During yarn grain rotates, yarn is easy the inertia rotated due to yarn grain and relaxation occurs and generates back twirl.In fabrication processes It returns and twists phenomenon, so that weaving can not be normally carried out, make troubles to production.

Based on problem above, a kind of yarn is set and prevents back twist device, returns and twists to avoid twist yarn, guarantee fabrication processes Orderly carry out.

Utility model content

The purpose of this utility model is that proposing that a kind of yarn prevents back twist device, return and twist to avoid twist yarn, guarantees to spin Knit the orderly progress of process.

For this purpose, the utility model uses following technical scheme:

A kind of yarn prevents back twist device, including bracket, and multiple support rods being parallel to the horizontal plane are provided on the bracket, The yarn prevents back twist device further include:

Bearing is mounted on the support rod；

Roller is set on the bearing；

Yarn grain is set on the roller, and the axial dimension of the yarn grain is less than the axial dimension of the roller；

Connecting line, along the circumferential across the surface of the roller of the roller, and one end connects the counterweight to hang in the sky Block, the other end connect traction device.

A kind of preferred embodiment of twist device is prevented back as above-mentioned yarn, the region that the roller is not covered by the yarn grain A circle groove is offered in circumferential direction, the connecting line is crossed in the groove.

Prevent back that a kind of preferred embodiment of twist device, the groove are arranged in the roller close to the branch as above-mentioned yarn One end of the junction of strut and the bracket.

Prevent back that a kind of preferred embodiment of twist device, the traction device are below the support rod or oblique as above-mentioned yarn Other support rods of lower section, the connecting line are lain on the traction device.

Prevent back that a kind of preferred embodiment of twist device, the bearing are two as above-mentioned yarn, two bearing difference It is correspondingly arranged at the both ends of the yarn grain.

Prevent back that a kind of preferred embodiment of twist device, the end of a thread of the yarn of the yarn grain are directed away from described as above-mentioned yarn The side of clump weight.

Prevent back that a kind of preferred embodiment of twist device, the bracket include vertical bar and crossbeam, the vertical bar as above-mentioned yarn It is mutually connected vertically with the crossbeam, the support rod is arranged on the vertical bar.

The utility model has the beneficial effects that

The utility model proposes yarn prevent back twist device, connecting line is under the action of clump weight and traction device to roller Surface apply pressure so that roller is during rotation by resistance, the revolving speed of rotation process middle roller is more steady, no Easily there is the phenomenon that accelerating suddenly, therefore, relaxation is less likely to occur the yarn on yarn grain, and the yarn of twisting is not easy to produce It returns and twists, can guarantee the orderly progress of fabrication processes.

Specific embodiment

Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.

As illustrated in fig. 1 and 2, present embodiment provides a kind of yarn and prevents back twist device, which prevents back that twist device includes branch Frame 1 is provided with multiple support rods 2 being parallel to the horizontal plane on bracket 1, and yarn prevents back that twist device further includes bearing 3, roller 4, yarn Grain 5, connecting line 6, clump weight 7 and traction device.Wherein, bearing 3 is mounted on support rod 2；Roller 4 is set on bearing 3；Yarn Grain 5 is set on roller 4, and the axial dimension of yarn grain 5 is less than the axial dimension of roller 4；Connecting line 6 along roller 4 it is circumferential across The surface of roller 4, and one end connects the clump weight 7 to hang in the sky, the other end connects traction device.

Yarn in present embodiment prevents back in twist device connecting line 6 under the action of clump weight 7 and traction device to sieve 4 outer circumference surface is drawn to apply pressure, so that roller 4 is during rotation by resistance, the revolving speed of rotation process middle roller 4 Relatively steadily, the phenomenon that being less prone to unexpected acceleration, therefore, relaxation, the yarn of twisting are less likely to occur the yarn on yarn grain 5 It is not easy to produce back twirl, can guarantee the orderly progress of fabrication processes.

In present embodiment, as shown in Figure 1, bracket 1 includes multiple vertical bars 11 and multiple crossbeams 12, crossbeam 12 connects adjacent Vertical bar 11, and crossbeam 12 is mutually perpendicular to vertical bar 11, and support rod 2 is arranged on vertical bar 11.Pass through vertical bar 11 and crossbeam 12 Vertical connection, bracket 1 can obtain good fastness and stability, guarantee the orderly progress of fabrication processes.

Since connecting line 6 is pressed on the surface of roller 4, and it is free end that connecting line 6, which connects one end of clump weight 7, is not had Structure is limited, and connecting line 6 is easy to happen offset, is even detached from roller 4 in order to avoid connecting line 6 deviates, as shown in Fig. 2, A circle groove 41 is not offered in the circumferential direction in the region that yarn grain 5 covers, connecting line 6 is crossed in groove 41.41 energy of groove Enough limitation connecting lines 6 guarantee that connecting line 6 and stablizing for roller 4 cooperate in the movement of 4 axial direction of roller.

Roller 4 is arranged in close to one end of support rod 2 and the junction of bracket 1 in groove 41, and the setting of groove 41 defines The position of clump weight 7, so that clump weight 7 avoids to prevent staff from accidentally encountering counterweight close to outside close to bracket 1 Block 7, is on the one hand avoided that and impacts to fabrication processes, is on the other hand also avoided that clump weight 7 injures staff.

Traction device is other support rods 2 of 2 lower section of support rod or obliquely downward, and connecting line 6 is lain on traction device.This leads The structure of leading-in device can be avoided increases new structure on the basis of existing textile apparatus, saves installation cost.

Bearing 3 is two, and two bearings 3 are separately positioned on the both ends of yarn grain 5, are not only simple in structure, and can be to yarn Grain 5 provides stable support.

The end of a thread of the yarn of yarn grain 5 is directed away from the side of clump weight 7, avoids phase between the end of a thread of yarn and clump weight 7 Mutually interference, guarantees that spinning process is gone on smoothly.

Note that above are only the preferred embodiment of the utility model.It will be appreciated by those skilled in the art that the utility model is not It is limited to specific embodiment described here, is able to carry out various apparent variations, readjustment for a person skilled in the art With substitution without departing from the protection scope of the utility model.Therefore, although being carried out by above embodiments to the utility model It is described in further detail, but the utility model is not limited only to above embodiments, is not departing from the utility model design In the case of, it can also include more other equivalent embodiments, and the scope of the utility model is determined by scope of the appended claims It is fixed.
