Abstract
The invention relates to a yarn break automatic stop device adopted on a twisting machine in the textile industry. The device comprises a pressing roll-roller pair for convening plied yarns and also comprises a lever mechanism consisting of a probe rod, a fulcrum and a guide block. The fulcrum is at the mass center of the lever mechanism, and the lever mechanism is fixed on a base through the fulcrum, wherein the base is connected with the twisting machine to form a whole; acting forces on the probe rod and the guide block on two sides of the fulcrum are twisting tension and gravity of a pressing roll respectively; and an eccentricity is formed between the centers of the pressing roll and a roller. During normal production, a torque produced by the twisting tension is greater than that produced by the gravity of the pressing roll, and the lever mechanism inclines left; and when the plied yarns are broken, the twisting tension disappears, the lever mechanism turns right under the gravity action of the pressing roll and rolls to a brake along the guide block so as to break automatic stop. The device has the advantages that a force system is formed by using the yarn twisting tension and the pressing roll gravity according to the mechanics principle, the yarn break automatic stop is realized by changing the torque, and the device has a simple structure, quick response and accurate and reliable motion.
Description
Technical field
The present invention relates to a kind of Yarn break and detect automatically and feed back control system, refer in particular to the Yarn break automatic stop device that adopts on the twisting machine in the textile industry.
Background technology
The automatic stop motion of traditional cotton, the twisting machine of wool spinning all adopts nylon inserted sheet form.When twisting thread, several strands of single thread are wrapped on the pressure roller by certain mode, and pressure roller is placed directly on the roller of twisting machine.Along with the rotation pressure roller of roller is constantly exported a strand yarn, the probe in the end break self-stop mechanism pushed down by strand yarn after the twizzle of twisting machine is twisted into strand under the steel wire hook effect of twisting machine.When output thigh yarn breakage; probe on the twisting machine in the self-stopping gear lifts because of the pressure that loses strand yarn; nylon inserted sheet in the drive self-stopping gear is to twisting machine roller and pressure roller intermediary movements; the nylon inserted sheet inserts between pressure roller and the roller; pressure roller stops operating under the rubbing action of nylon6 chips when disengaging with roller, thereby stops output strand yarn.
Such self-stopping gear has several defectives: 1. probe is that the finer wire bending forms easy deformation.Probe location after the distortion and application point all can change, thereby the motion path of the nylon inserted sheet that is attached thereto and distance are all changed.Behind strand yarn breakage, though probe is upspring, the nylon inserted sheet can not effectively inject between pressure roller and the roller, and pressure roller can not break away from and the contacting and stopping operating of roller fully, can not accomplish a strand automatic stop when an end breaks; 2. the nylon inserted sheet in the mechanism is warped and fractured easily and is worn and torn, so that can't correctly insert between pressure roller and the roller, can not stop the rotation of pressure roller effectively, does not reach the purpose because of the broken end automatic stop of twisting thread.Sometimes the nylon inserted sheet can't withdraw between pressure roller and roller fully, makes the hypotaxia of pressure roller for the thigh yarn, thereby produces loosely spun yarn; Sometimes because of the position is inaccurate pressure roller has been produced braking action after the nylon inserted sheet resets fully, the pressure roller rotating speed has been slowed down, thereby crepe twist yarn occurs.Above-mentioned situation all causes the decline of yarn qualities and row yielding.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, easy to operate, be quick on the draw, move Yarn break automatic stop device accurately and reliably.
Yarn break automatic stop device provided by the invention comprises that pressure roller, the roller of output strand yarn is right, it is characterized in that also comprising a leverage, this leverage is made up of feeler lever, fulcrum and guide pad, described fulcrum is at the barycenter place of leverage, and whole leverage is fixed on the pedestal that fuses with twisting machine by this fulcrum; The feeler lever of leverage fulcrum both sides and the active force on the guide pad are respectively the gravity of yarn twisting tension and pressure roller; There is an eccentric throw at described pressure roller center in a side at described roller center between pressure roller center and the roller center, the back lower place of pressure roller is provided with a pressure roller brake that is connected as a single entity with twisting machine.
Affiliated pressure roller diameter is 72mm, and pressure roller central shaft diameter is 12mm, and pressure roller and pressure roller central shaft are as a whole.
The material of described feeler lever is that diameter is the stainless steel wire of 4mm, walks the yarn position on the feeler lever and is provided with ceramic guide.
The material of described guide pad is engineering plastics.
Described pedestal top is provided with positive stop.
On the described pressure roller brake absorbing material is arranged.
Described roller surface is done the hard chrome plating polishing.
Advantage of the present invention is according to mechanics principle, utilizes yarn twisting tension and pressure roller gravity to form a power system, reaches the purpose of Yarn break automatic stop with simple moment variations.The Yarn break automatic stop device of this employing leverage, simple in structure, reaction is quick, and action is accurately and reliably.

The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is mechanics principle figure of the present invention.Feeler lever 3, balance pivot 11 and guide pad 14 are formed a leverage among the figure, and the power that the twisting tension of twisting thread acts on the feeler lever 3 is F1, and the pressure that pressure roller 1 acts on the guide pad 14 is F2.During moment that the moment that produces as F1 produces greater than F2, lever is done counterclockwise and is rotated, and pressure roller 1 is close to roller 8 surfaces, and the present invention guarantees that F1 is not large enough to can make pressure roller move to the highest point of roller along surface of roller; During moment that the moment that produces as F2 produces greater than F1, arm bar transfers to clockwise direction and rotates, and pressure roller 1 rolls in the direction of the effect lower edge of gravity guide pad 14 defineds, hightails and the contacting of roller 8.
Fig. 6 is ordinary production embodiment of the present invention, feeler lever 3, fulcrum 11, guide pad 14 are formed a leverage, and fulcrum 11 is in the centroid position of lever, and fulcrum 11 is placed on the pedestal 9, pedestal 9 is fixed on the frame of twisting machine, and whole leverage can be that the center swings with fulcrum 11.Pedestal 9 has two kinds of right-hand men and positive stop 12 is arranged.The center of pressure roller 1 has an eccentric throw between the two in a side at roller 8 centers.A brake 10 that is connected as a single entity with twisting machine has also been designed in the back lower place of nip roll 1.
Embodiment when Fig. 7 is a strand yarn breakage.In case strand yarn 13 fractures, the tension force of twisting thread disappears, whole leverage is upset immediately under the gravity effect of pressure roller 1, pressure roller 1 is backward rotation immediately, and a strand yarn 13 is no longer exported, and pressure roller 1 rolls in the direction of the effect lower edge of gravity guide pad 14 defineds, hightail and the contacting of roller 8, stop at last on the brake 10, a strand yarn 13 is no longer exported, and has realized end break self-stop.
