Description

Front-end tensioner of weft feeder of arrow loom

technical field

The invention relates to a front-end tensioner of a weft feeder of an arrow loom.

Background technique

The tensioner installed at the front end of the weft feeder of the arrow loom has a variety of structures, including ring type, jaw type, column type, casing type, and heavy hammer type. When the weft thread is pulled through the tensioner, the tensioner The damping effect on the weft creates a certain tension on the weft to adjust the tension on the weft before the weft insertion starts, so as to control the fluctuation of the tension on the weft during the weft insertion movement.

In the prior art, the weft thread simply damps the weft thread through the tensioner, which cannot simultaneously improve the hairiness, smoothness, and static electricity removal of the weft thread such as cotton thread, wool thread, and chemical fiber elastic thread. Collapsing weft and broken end defects.

Contents of the invention

The purpose of the present invention is to improve the deficiencies of the above-mentioned prior art, and provide a method that can not only keep the initial tension of weft insertion stable and moderate, and meet the technological requirements, but also can conveniently and quickly smooth the hairiness, wax, and oil the weft. , improve the smoothness of the weft, reduce friction and eliminate static electricity. In order to overcome problems such as lack of weft and broken ends during weaving, so as to ensure product quality.

The present invention is composed of a connecting frame 1, a front wire column 2, a rear wire column 3, a tension roller 4, a wax column 5, and an oil immersion box 6. The front end of the connecting frame 1 has a wire plate 11, and the wire plate 11 is provided with an inlet hole 12. , There is a connecting plate 13 at the rear end of the connecting frame 1, and an outlet hole 14 is opened on the connecting plate 13. The tension roller 4 is installed on the bottom plate 10 of the connecting frame 1 through the rotation of the bearing 40. The tension roller 4 is provided with a damping wire tray 41, The damping wire support disc 41 is connected with the shaft shoulder provided on the tension roller 4 through the central shaft hole and is rotationally fitted. The wax column 5 is inserted on the tension roller 4 through the central shaft hole and sits on the damping wire support disc 41. And the rear wire column 3 is fixedly connected and installed with the connecting frame 1 bottom plate 10 and is respectively arranged on the front and rear parts of the tension roller 4. There is a (tension adjustment) chute 21 on the connecting frame 1 bottom plate 10, and the front wire post 2 is fixedly installed on the sliding On the groove 21; the oil immersion box 6 is arranged at the rear portion of the rear wire column 3, and the oil immersion box 6 is composed of an oil immersion box body 61, a lid 62, a crimping shaft 63 and a sponge body arranged in the oil immersion box body 61 64 forms, on the front and back box wall of oil immersion box body 61, offer line inlet and outlet notch 66,67, crimping axle bar 63 action latitude a contacts with sponge body 64, carries out oiling process to weft a.

The invention has the advantages of simple structure, convenient manufacture, small size and convenient installation and use. When in use, the latitude a enters through the wire hole 12 on the front end wire plate 11 of the connecting frame 1, and passes on the damping wire support disc 41 of the tension roller 4 after being guided by the front wire post 2, and the wax column 5 on the damping wire support disc 41 The bottom surface of the wax column 5 is pressed on the latitude a, and the bottom surface of the wax column 5 rubs against the passing weft a to make the wax column 5 automatically rotate. The bottom of the wax column 5 is waxed on the passing weft a, and is installed on the bottom plate of the connecting frame through the rotation of the bearing 40. The tension roller 4 on the 10 and the Nituo line disc 41 that rotates and cooperates with the shaft shoulder that offers on the tension roller 4 through the central shaft hole can produce follow-up rotation under the frictional force of the rotating wax column 5, so that the wax column 5 and The relative rotation speed of the tension roller 4 and the nito wire reel 41 is automatically reduced, thereby achieving automatic balance and stability of the wax column 5, ensuring that the wax column 5 does not produce too much relative rotational friction and floating with the nito wire reel 41, so that the wax column 5 Wax the weft thread a for stabilization.

Weft thread a passes through oil immersion box 6 through rear wire post 3, and the crimping shaft bar 63 on the oil immersion box 6 cooperates to carry out oiling process to weft thread a.

The present invention can adopt the processing of waxing or oiling separately according to the specific situation of weft thread a kind, also can use simultaneously.

The weft thread a of the present invention can simultaneously achieve the fuzzy effect on the weft thread a during the above-mentioned movement process, improve the smoothness of the weft thread, reduce the frictional resistance of the weft thread a and the static electricity caused by friction, and effectively overcome the lack of weft when weft weaving. Broken head and other problems, so as to ensure product quality.
