Detailed Description

Referring to fig. 1, the utility model provides a waste yarn guiding mechanism of a loom, which comprises a waste yarn guide plate 100, wherein a waste yarn outlet 101 and a yarn guide wheel 102 are arranged on the waste yarn guide plate 100; one side of the waste yarn guide plate 100 is connected with a vertically arranged protective side plate 200; referring to fig. 2, the waste yarn is guided out from the waste yarn outlet 101, guided to the outside of the guard side plate 200 by the yarn guide roller 102, and the waste yarn strip 300 falls in a vertical state by gravity.

Two driving chain wheels 1 which are positioned in the same vertical plane are arranged on the protective side plate 200, and a yarn guide chain 11 is wound between the two driving chain wheels 1; a plurality of yarn dragging clamps 3 are fixedly arranged on the yarn guide chain 11 at equal intervals;

referring to fig. 3, the yarn pulling clamp 3 comprises a fixed claw 31 and an elastic claw 32; the roots of the fixed claw 31 and the elastic claw 32 are fixedly connected in an attaching manner, and the end parts of the fixed claw and the elastic claw are respectively provided with a clamping piece 33;

referring to fig. 5, the protective side plate 200 is further vertically provided with an opening and closing strip 2 for attaching or separating two clamping pieces 33 of the yarn pulling clamp 3 to each other; the opening and closing strip 2 is provided with a smooth section, and two ends of the smooth section are respectively connected with an inclined section;

in the relaxed state, the holding pieces 33 of the fixed claws 31 and the elastic claws 32 are separated; when the yarn guide chain 11 moves to the position of the opening and closing strip 2, the waste yarn strip 300 enters between the two clamping pieces 33; then, the elastic claw 32 abuts on the inclined section at the upper end of the opening and closing bar 2 and gradually approaches the fixed claw 31 along with the movement of the yarn guide chain 11. Until it moves onto the smooth section, the gripping tab 33 of the resilient claw 32 fits tightly against the gripping tab 33 of the fixed claw 31, thereby gripping the waste sliver 300. The waste sliver 300 is drawn down to facilitate the drawing-out thereof along with the driving of the yarn guide chain 11. And the elastic claw 32 is elastically restored to the initial state when the yarn continuously moves to the inclined section at the lower end of the opening and closing strip 2, and the two clamping pieces 33 are separated from the waste yarn strip 300.

The holding piece 33 is preferably made of rubber or silicone rubber in order to maintain a sufficient pulling force on the waste yarn 300.

According to different equipment specifications, the yarn dragging clamps 3 on the yarn guide chain 11 of the utility model are adaptively set to be 6-10;

the utility model discloses a drag yarn clamp 3 can adopt the mode of welding or bonding to fix on leading yarn chain 11, if weld the stationary dog 31 on leading yarn chain 11.

In practical use, the elastic claw 32 and the clamping piece 33 belong to wearing parts. For the convenience of replacement, referring to fig. 4, the detachable yarn pulling clamp 3 of the present invention is fixed on the claw body fixing seat 34, and the claw body fixing seat 34 is fixed on the yarn guiding chain 11.

Preferably, the claw body fixing seat 34 has a fixing slot, and the roots of the fixing claw 31 and the elastic claw 32 are inserted into the fixing slot; the fixation of the yarn pulling clamp 3 is realized by bolts or screws.

The utility model discloses a claw body fixing base 34 can weld in advance on leading yarn chain 11, when on-the-spot equipment debugging, will drag yarn clamp 3 and fix in claw body fixing base 34, has made things convenient for manufacturing and installation work, and the dismantlement when being convenient for simultaneously maintain is changed.

There is inevitably a difference between the drawing-out speed of the waste sliver 300 and the drawing-in speed of the yarn puller 3. When the difference is small, the elastic deformation of the waste sliver 300 is enough to compensate; when the difference is large, the waste sliver 300 is at risk of being torn, resulting in discontinuity in the yarn output.

As a preferable mode, in order to avoid the above situation, an adjusting groove 21 is formed on the smooth section of the opening and closing strip 2; when the elastic claw 32 moves to the adjustment groove 21, the two holding pieces 33 are temporarily separated, and the tensioned waste yarn strip 300 is elastically retracted to avoid the stretch-breaking. And then moved to the smooth section for clamping again. Preferably, the number of the adjustment grooves 21 is set to 3 to 5 according to the length of the smooth section. Furthermore, the cross section of the adjusting groove 21 is arc-shaped, so that the loosening and clamping actions are stable and smooth.

In summary, the utility model provides a waste yarn guiding mechanism of a weaving machine, which is characterized in that a plurality of yarn dragging clamps are arranged on a yarn guide chain, and the yarn dragging clamps clamp and drag waste yarn strips downwards in the process of moving downwards along with the yarn guide chain, so as to promote the guiding of the waste yarn; before reversing, the yarn dragging clamp is elastically loosened to be separated from the waste yarn strips. The utility model discloses a waste yarn is derived to the mode of dragging, avoids appearing the winding condition of waste sliver.

Naturally, the present invention can be embodied in many other forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be made by one skilled in the art without departing from the spirit or essential attributes thereof, and it is intended that all such changes and modifications be considered as within the scope of the appended claims.
