Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0012] In the accompanying drawings: fixed column 1, bobbin main shaft 2, friction plate 3, friction crank arm 4, groove 5, friction end 6, drive end 7, crank arm axis 8, torsion spring mechanism 9, moving guide wheel 10, Moving wire wheel connecting shaft 11, fixed wire wheel 12, fixed wire wheel connecting shaft 13, swing connecting rod 14.

[0013] A new type of friction unwinding device for bobbins, comprising a fixed column 1, a bobbin spindle 2, and a friction control assembly. The arm axis 8 rubs against the crank arm 4 and the friction disc 3 is arranged at the other end of the bobbin main shaft 2 . The cylindrical surface of the friction disc 3 is provided with grooves 5 . The friction crank arm 4 includes a friction end 6 and a driving end 7, and the profile of the friction end 6 matches the profile of the groove 5, so that the d...

Abstract

The invention relates to a novel friction-type cone yarn unwinding device which comprises a fixing column, a cone yarn spindle and a friction control component. One end of the cone yarn spindle is movably connected with the fixing column, the friction control component comprises a friction disc and a friction crank arm provided with a crank arm shaft, and the friction disc is arranged at the other end of the cone yarn spindle; a groove is arranged in the cylindrical surface of the friction disc; the friction crank arm comprises a friction end and a driving end, and the friction end is matched with the groove in contour. The novel friction-type cone yarn unwinding device has the advantages that service life is obviously prolonged, and structure is simpler.

Description

technical field [0001] The invention relates to a textile machine, in particular to a novel friction type bobbin unwinding device. The unwinding device has a simple structure and a long service life. Background technique [0002] In the prior art, the bobbin unwinding device is a device used in a warp frame. The device ensures that the yarn has sufficient tension during the releasing process of the yarn of the bobbin, so that the yarn is in a stretched and tensioned state during processing, which is convenient for processing. Yarn tension adjustment has the initial way that the operator manually increases or decreases the number of counterweights, and develops to control the tension of the yarn through friction. For example, the patent with the publication number of 202464933U describes "a self-adjustable tension-adjustable bobbin unwinding mechanism". Thread tension. But because parts such as above-mentioned belt and spring all and expose with the outside world. Because...
