Abstract

The utility model discloses a kind of to yarn mechanism, comprise yarn bobbin, guide wire, yarn-guiding loop and thread-carrier, described yarn-guiding loop comprises yarn-guiding loop and lower yarn-guiding loop, tensioner is provided with between described upper yarn-guiding loop and lower yarn-guiding loop, described yarn bobbin cross section is up-narrow and down-wide isosceles trapezoidal structure and is that opposed vertical is placed with ground, about its top, two end points upwards extend formation one bobbin coning angle A, about its underpart, two end points upwards extend and form a guide cheicers B with the center-point of the first guide wire, the angle of described guide cheicers B is less than bobbin coning angle A.

Description

A kind of to yarn mechanism

Technical field

The utility model relates to a kind of to yarn mechanism.

Background technology

Some on existing market give yarn mechanism, design unreasonable, especially the angle design of yarn bobbin and guide wire is unreasonable, cause yarn large from resistance during bobbin unwinding, because yarn is relevant with the placed angle of bobbin from Tensity size during bobbin unwinding, when bobbin is vertically placed relative to ground, the size of unwinding tension is subject to the impact of guide wire and bobbin height, its highly arrange and the setting of angle very crucial for drag size during bobbin unwinding.

Summary of the invention

The purpose of this utility model designs one to yarn mechanism.

To be solved in the utility model is that more existing to yarn mechanism, design unreasonable, especially the angle design of yarn bobbin and guide wire is unreasonable, causes yarn from the large problem of resistance during bobbin unwinding.

The technical solution of the utility model is: it comprises yarn bobbin, guide wire, yarn-guiding loop and thread-carrier, described yarn-guiding loop comprises yarn-guiding loop and lower yarn-guiding loop, tensioner is provided with between described upper yarn-guiding loop and lower yarn-guiding loop, described yarn bobbin cross section is up-narrow and down-wide isosceles trapezoidal structure and is that opposed vertical is placed with ground, about its top, two end points upwards extend formation one bobbin coning angle A, about its underpart, two end points upwards extend and form a guide cheicers B with the center-point of the first guide wire, the angle of described guide cheicers B is less than bobbin coning angle A.

Advantage of the present utility model: the height of bobbin should make the surface from touching bobbin during the unwinding of bobbin bottom be advisable, namely the angle of the guide cheicers B of the utility model setting is less than bobbin coning angle A, so just can reduce the friction of yarn and bobbin surface, to reduce tension fluctuation during unwinding.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further detail.

As shown in the figure, the utility model comprises yarn bobbin 1, guide wire 2, yarn-guiding loop and thread-carrier 8, yarn 4 from yarn bobbin 1 out, respectively through guide wire 2, yarn-guiding loop and thread-carrier 8, described yarn-guiding loop comprises yarn-guiding loop 3 and lower yarn-guiding loop 6, tensioner 5 is provided with between described upper yarn-guiding loop 3 and lower yarn-guiding loop 6, described yarn bobbin 1 cross section is up-narrow and down-wide isosceles trapezoidal structure and is that opposed vertical is placed with ground, about yarn bobbin top, two end points upwards extend formation one bobbin coning angle A, about yarn bobbin bottom, two end points upwards extend and form a guide cheicers B with the center-point of the first guide wire, the angle of described guide cheicers B is less than bobbin coning angle A.

Described upper yarn-guiding loop 3 and lower yarn-guiding loop 6 are located at the bottom of guide wire 2, and the bottom of lower yarn-guiding loop 6 is located at by described thread-carrier 8.
