Description

Chenille machine prevents uneven structure of fine hair

Technical Field

The utility model belongs to the technical field of the textile technology and specifically relates to a chenille machine prevents uneven structure of fine hair.

Background

The chenille spinning machine is spinning equipment for producing chenille yarns, the chenille yarns have fluffy and plump fluff, soft handfeel and bright colors, and are widely applied to household decorative fabrics, automobile decorative fabrics and garment fabrics at present.

The chenille yarn mainly comprises two core yarns 10 and a plurality of pile yarns 101 (pile fibers), and the specific weaving mode is as described in journal articles: described in "Jiangsu textile" (11-st. populi aspiration 2005): the weaving of the denier yarns is carried out by utilizing components such as a rotating head, a cutting distance piece 103, a cutting knife 102 and the like;

referring to fig. 1, one chenille head produces two chenille yarns at the same time, each rotary head produces two chenille yarns at the same time, each chenille yarn being composed of two core yarns 10 and several tufts of pile yarns 101 (or pile fibers);

during the weaving process, two core yarns 10 are converged under the guidance of the first roller 104 and the second roller 105 respectively, and form the subsequent twisting; the rotating head winds the loop pile yarn 101 around the outer periphery of the cutting distance piece 103 in a looping manner, the cutter 102 continuously cuts the looped pile yarn 101 into two and a half loops, and a short pile is formed and clamped in the twist of the two core yarns 10 to form the chenille yarn.

Before the twisting is completed, the two core yarns 10 need to be guided by the left/right swing arms, so that the cut pile yarns 101 and the core yarns 10 form a proper position matching relationship in the twisting stage, in other words, the middle point of the pile yarns 101 can be just clamped in the twisting turns of the two core yarns 10.

Referring to fig. 3, the existing swing arm structure includes a roller swing arm 1, a positioning sleeve 11 is fixed at one end of the roller swing arm 1, a roller shaft 12 penetrates through the positioning sleeve 11 in a rotating manner, an axial line of the roller shaft 12 is parallel to a central axis of the positioning sleeve 11, and the roller shaft 12 is fixed with the positioning sleeve 11 along an axial direction thereof; one end of the roller shaft 12 is connected with a driving component to drive the roller shaft 12 to rotate circumferentially, the other end of the roller shaft 12 is fixedly sleeved with a roller piece 13, the periphery of the roller piece 13 is provided with an annular guide groove 14, and the guide groove 14 is used for guiding the core yarn 10.

The other end of the roller swing arm 1 is fixed with a sleeve 2, the central axis of the sleeve 2 is parallel to the axis of the roller shaft 12, the sleeve 2 is connected with the integrated board 15 through a positioning bolt 21 and a positioning nut 22, and components such as a rotating head, a cutting distance sheet 103 and a cutting knife 102 are all installed on the integrated board 15.
