Example 1

As shown in fig. 1-3, this embodiment provides a roving frame 10, which includes a roving frame body 1, an annular lapping area 2 is provided on an outer sidewall of the roving frame body 1, a center line of the annular lapping area 2 coincides with an axis of the roving frame body 1, a plurality of protruding portions 3 are arranged on the annular lapping area 2, and each protruding portion 3 can extend into a thick yarn and fix a thread end of the thick yarn in the annular lapping area 2.

According to the roving bobbin 10 provided by the embodiment, the protruding parts 3 are arranged on the annular lapping area 2 of the roving bobbin body 1, the thread ends of the roving are fixed in the annular lapping area 2 by extending the protruding parts 3 into the roving, the distribution density of the protruding parts 3 is smaller than the density of fluff on the sticky lint, the protruding height of the protruding parts 3 is smaller than the length of the fluff, the acting force applied to the roving can be effectively reduced, the risk of roving disconnection can be effectively reduced when the roving is unwound, the starting lapping can be completed, the roving residues can be effectively avoided when the roving is unwound, the purposes of no chemical fiber and no residual yarn are achieved in the unwinding process, the use is convenient, the labor intensity is reduced, the labor is effectively saved, and the cotton yarn is saved; in this embodiment, each protruding portion 3 and the roving frame body 1 are of an integral plastic structure, and because the electrostatic action between each plastic protruding portion 3 and the roving frame is far smaller than the electrostatic action between the sticky lint and the roving frame, the risk of disconnection of the roving frame can be reduced more effectively.

Further, each protruding portion 3 is a pointed protruding portion so as to extend into the thick yarn to finish lapping, and to avoid roving residues during unwinding.

Furthermore, each protruding part 3 is uniformly distributed in the annular wire-lapping area 2, so that the structure is simple, and the manufacture and the use are convenient.

In this embodiment, the protruding portion 3 has three side edges, and the three side edges intersect at a point, that is, the cross section of each protruding portion 3 gradually decreases from the roving bobbin body 1 to one end of each protruding portion 3 far away from the roving bobbin body 1, so that each protruding portion 3 can extend into the thick yarn and make the thread end of the thick yarn fixed in the annular thread-lapping area 2, and the structure is simple, and the thread lapping and unwinding are facilitated.
