Abstract
Yarn tightening device on a kind of bobbin-winding machine, comprise the base plate of rectangle, oval coiling block is pressed against at the middle part in base plate front, the aft end face of coiling block forms pillar, pillar is inserted with torsion spring through base plate, one end of torsion spring is fixed on pillar, the other end is pressed against on limited post, and limited post is fixed on the back side of base plate; In there being spiral winding slot on the outer wall of described coiling block; Right two jiaos of described bottom plate inclined are plugged with the thread-carrier of pigtail type, and there is stud one end of thread-carrier through baseplate molding, and another tiltedly right two jiaos of base plate are plugged with bolt.It adopts oval coiling block to realize yarn with the thread-carrier matched, the length of yarn between thread-carrier is changed by wrapping post rotational, and then give coiling block tensile force by torsion spring, thus realize the tensioning of yarn, avoid Yarn relaxation to tie a knot, the generation of stuck, the phenomenon that breaks.
Description
technical field:
The utility model relates to the technical field of bobbin-winding machine, more specifically to the yarn tightening device on a kind of bobbin-winding machine.
background technology:
Bobbin-winding machine is the specialized equipment of textile industry, and winder, as last procedure spinned and woven first working procedure, plays " bridge " effect of forming a connecting link, thus occupies an important position in field of textiles.Coupled together by cop (or reeled yarn) less for capacity by winder, the bobbin that capacity of making is larger, the capacity of a bobbin is equivalent to more than 20 cop.Bobbin can be used for warping, and twists with the fingers, quilling, dyeing, the weft yarn on shuttleless loom and knitting yarn etc.And the conveying of yarn is formed longer between little cop and large bobbin, need to carry out tensioning to its yarn.
utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and provides the tightening device of the yarn on a kind of bobbin-winding machine, and it can carry out tensioning to the yarn on bobbin-winding machine.
Technology solution of the present utility model is as follows:
Yarn tightening device on a kind of bobbin-winding machine, comprise the base plate of rectangle, oval coiling block is pressed against at the middle part in base plate front, the aft end face of coiling block forms pillar, pillar is inserted with torsion spring through base plate, one end of torsion spring is fixed on pillar, the other end is pressed against on limited post, and limited post is fixed on the back side of base plate; In there being spiral winding slot on the outer wall of described coiling block; Right two jiaos of described bottom plate inclined are plugged with the thread-carrier of pigtail type, and there is stud one end of thread-carrier through baseplate molding, and another tiltedly right two jiaos of base plate are plugged with bolt.
The aft end face of described coiling block upper supporting column is fixedly connected with block.
Described stud and through base plate bolt on be plugged with spacer, the length of spacer is greater than the length of coiling block upper supporting column.
Described coiling block forms vallecular cavity, and on the inwall of vallecular cavity, the shaping oil leaking hole be connected with winding slot, the front end face of coiling block is fixed with cover plate.
The beneficial effects of the utility model are:
1, the coiling block that its employing is oval and the thread-carrier matched realize yarn, the length of yarn between thread-carrier is changed by wrapping post rotational, and then give coiling block tensile force by torsion spring, thus realize the tensioning of yarn, avoid Yarn relaxation to tie a knot, the generation of stuck, the phenomenon that breaks.
2, the tightening device that it adopts can also oil to yarn, and lubricated yarn, avoids yarn stuck.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that the utility model changes angle;
Fig. 3 is the structural representation that the utility model changes angle;
Fig. 4 is the structural representation of the utility model without cover plate.
In figure: 1, base plate; 2, coiling block; 3, torsion spring; 4, limited post; 5, thread-carrier; 6, bolt; 7, block; 8, cover plate; 9, spacer; 21, pillar; 22, winding slot; 23, vallecular cavity; 24, oil leaking hole; 51, stud.
detailed description of the invention:
Embodiment: see shown in Fig. 1 to 4, yarn tightening device on a kind of bobbin-winding machine, comprise the base plate 1 of rectangle, oval coiling block 2 is pressed against at the middle part in base plate 1 front, the aft end face of coiling block 2 forms pillar 21, pillar 21 is inserted with torsion spring 3 through base plate 1, and one end of torsion spring 3 is fixed on pillar 21, the other end is pressed against on limited post 4, and limited post 4 is fixed on the back side of base plate 1; In there being spiral winding slot 22 on the outer wall of described coiling block 2; Tiltedly right two jiaos of described base plate 1 are plugged with the thread-carrier 5 of pigtail type, and there is stud 51 one end of thread-carrier 5 through baseplate molding, and another tiltedly right two jiaos of base plate 1 are plugged with bolt 6.
The aft end face of described coiling block 2 upper supporting column 21 is fixedly connected with block 7.
Described stud 51 and through base plate 1 bolt 6 on be plugged with spacer 9, the length of spacer 9 is greater than the length of coiling block 2 upper supporting column 21.
Described coiling block 2 forms vallecular cavity 23, and on the inwall of vallecular cavity 23, the shaping oil leaking hole 24 be connected with winding slot 22, the front end face of coiling block 2 is fixed with cover plate 8.
Principle of work: base plate 1 is fixed on bobbin-winding machine by the stud 51 on thread-carrier 5 and bolt 6 by the utility model, and the coiling block 2 of ellipse is positioned at the middle part of base plate 1, thread-carrier 5 is positioned at the both sides of coiling block 2, yarn enters from the thread-carrier 5 of one end, at coiling block more than 2 circle around the home, yarn is in winding slot 22, go out at the thread-carrier 5 through the other end, and coiling block 2 rotational changes the length of yarn between thread-carrier 5, thus tensioning is carried out to yarn, the power that its coiling block 2 rotates is provided by torsion spring 3, thus carries out tensioning to yarn; Thus can lubricating grease be filled in the vallecular cavity 23 of coiling block 2, grease thus oil leaking hole 24 can to around the home on coiling block 2 yarn lubricate.
