Description

The let-off motion of braiding machine

Technical field

The utility model relates to the textile machine technology, especially relates to the let-off motion that is used for the braiding machine of warp-feeding mechanism on a kind of extraordinary loom.

Background technology

Extraordinary loom is meant and is used to weave the loom of the few heavily fabric of the thick radical of yarn as the water spray braiding machine.Extraordinary loom does not generally use beam of a loom, and the warp thread of creel (warp thread collating unit) directly enters the warp thread feeding unit on the loom, finishes the warp let-off, carries out weaving process after entering shedding motion again.The warp thread feeding unit is many to be made up of several guide roller (as the tension force buffer roll that cord roller, feeding dance roller, friction rod, capstan roll is arranged, contain regulating spring commonly used), these several cylinders do not have active force, warp thread is in the warp let-off and whole motion process, tractive force is all from the dominant cloth roll on the loom, promptly drives dominant cloth roll by main motor (clockwise and anticlockwise motor) on the loom and drives and drawing movement of the warp when cloth beam rotates batching synchronously at the friction roller that batches of finishing selvage guide and driving spooler.The control of warp tension then is to regulate by the tension force buffer roll in the warp thread feeding unit, promptly from the warp let-off to the whole manufacturing process, warp thread is to provide traction power by dominant cloth roll, and the direct hard draw of warp thread is gone into loom.

Like this, the warp-feeding mechanism of water spray braiding machine can cause existing following problem in weaving process:

The Tension Control of common water spray braiding machine relies on the control of warp thread feeding unit, and the guide roller of warp thread feeding unit all is passive not having initiatively.In weaving process, during scrams such as appearance staplings, the few latitude of empty latitude can appear, if continuing start weaves, can cause rare shelves (park) defective cloth, principle is exactly because staplings is when stopping, owing to the motional inertia of warp thread can continue the segment distance that moves ahead, can't aim at the cloth mouth, and make the rare shelves of adjacent weft appearance on the cloth cause few latitude.When this situation usually occurring, the reversing of shelves turner operation control dominant cloth roll, but because the guide roller of warp thread feeding unit does not have dynamic Control can't follow the dominant cloth roll reversing, make loom can't aim at the cloth mouth, be that the cloth mouth retreats under dominant cloth roll control, but the warp thread between dominant cloth roll and warp thread feeding unit does not retreat, and loose warp occurring can't start shooting.Do not return rare grade of generation at one's discretion so sometimes this class situation is not simply done warp thread.Produce serious fabric quality problem, reduced product qualified rate.

Summary of the invention

Technical problem to be solved in the utility model has provided a kind of tension force that makes the water spray braiding machine make cloth cover and warp thread when stopping and has kept constant in the cloth mouth, thereby eliminates the few latitude of rare shelves, rare grade the let-off motion of braiding machine of avoiding occurring stopping.

For solving the problems of the technologies described above, the technical solution of the utility model is: the let-off motion of braiding machine, comprise warp thread feeding unit and the dominant cloth roll that drives by power set, described warp thread feeding unit is provided with the warp thread capstan roll that is used to guide warp thread, this let-off motion also includes the slip compensation device, the described dominant cloth roll slip compensation device that is in transmission connection, the described slip compensation device described warp thread capstan roll that is in transmission connection.

As a kind of improvement, described warp thread feeding unit also is provided with cord roller, friction roller and warp tension buffer roll, described cord roller, friction roller, warp thread capstan roll and warp tension buffer roll set gradually along the warp thread direct of travel, are provided with warp thread feeding dance roller between described cord roller and the friction roller.

As further improvement, described slip compensation device is included in to rotate successively on coaxial and is provided with main slippage dish, passive slippage dish, be provided with the frictional damping sheet between described main slippage dish, the passive slippage dish, be positioned at described passive slippage dish and be provided with slip compensation away from a side of main slippage dish and regulate elastic device.

The let-off motion of the braiding machine of technique scheme, owing to be the dominant cloth roll that adopts the warp thread feeding unit and drive by power set, the warp thread feeding unit is provided with the warp thread capstan roll that is used to guide warp thread, this let-off motion also includes the slip compensation device, the dominant cloth roll slip compensation device that is in transmission connection, the slip compensation device warp thread capstan roll that is in transmission connection, import dominant cloth roll into drive warp thread feeding unit warp thread capstan roll rotating speed by the slip compensation device and cushion adjustment, cause the excessive and infringement that warp thread is caused of warp tension when avoiding the rotating speed rotating to change, like this at scrams such as staplings, rare shelves appear need be to the cloth mouth time, the reversing of operation control dominant cloth roll is return a segment distance with cloth; Dominant cloth roll is by the slip compensation device simultaneously, control warp thread feeding unit synchronous interaction reversing, warp thread is return a segment distance, and since be used to drive in the spooler cloth beam batch friction roller also with the dominant cloth roll synchronous interaction, control cloth mouth retreats, thereby the tension force that makes cloth cover and warp thread keeps constant, move back cloth after normal starting drive, prevented rare grade generation.Realized that braiding machine is when scram occurs rare grade, synchronously simultaneously,, interlock control spooler batches friction roller reversing and the reversing of warp thread feeding unit cylinder, make the tension force of cloth cover and warp thread keep constant to the cloth mouth, eliminated the few latitude of rare shelves, reach and handling dominant cloth roll while adjusted in concert warp thread capstan roll and batching friction roller, easy and simple to handle, convenient control reversing distance, this can't finish on other special type braiding type.And the warp thread feeding unit also is provided with cord roller, friction roller and warp tension buffer roll, and is provided with warp thread feeding dance roller between cord roller and the friction roller, makes warp thread import evenly, and Tension Control is convenient.
