Description

Warp rebeaming machine slurry axle unwinding tension control device

Technical field

The utility model relate to a kind of and slurry silk machine and water jet looms supporting, to the unwinding the warp tenslator on the slurry axle of warp rebeaming machine, belong to warp rebeaming machine tenslator technical field in the textile machine.

Background technology

Before the knitting of water jet looms preparation mainly comprise warping, sizing and and axle, wherein, and the purpose of axle be with through the slurry axle in batch behind the last slurry process around to beam of a loom, thereby form bigger beam of a loom.In order to guarantee the beam winding quality, satisfy the follow-up high-quality needs of weaving, require and the axle process in, guarantee that the tension force of warp thread should be even, constant.

And the axle process is mainly divided the unwinding of pulping axle and two stages of beam winding.Early stage warp rebeaming machine slurry axle unwinding tension control system adopts a slurry axle friction stopping device, to and close after silk sheet tension force detect, but can't control separately each slurry axle, and tension feedback low-response, the tension force monitoring lags behind, and can't satisfy the production demand, thereby be eliminated gradually; When the mode of employing magnetic powder brake is controlled tension force, its principle is based on magnetic powder brake unwinding pedestal, form slurry axle unwinding tension automatic control system energy, the tension variation of each slurry axle of the enough independent detection of this mode, and can make response rapidly, but in the use, have that heating is serious, tension force control is inhomogeneous, control accuracy is relatively poor, maintenance cost is high, can't be competent at a high speed and shortcomings such as axle; Modes such as the pedestal design of steel band damping control tension force or sensor then because there being problem such as control lag, can't really satisfy the demand of production.

Have based on this, make the utility model.

The utility model content

The purpose of this utility model is to provide a kind of and overcomes above-mentioned shortcoming and can make the constant a kind of warp rebeaming machine slurry axle unwinding tension control device of retention tab yarn tension when starching the axle unwinding.

For achieving the above object, the technical scheme that adopts of the utility model is as follows:

Warp rebeaming machine slurry axle unwinding tension control device comprises head and several slurry axles, and described each slurry axle all disposes independently unwinding tension measuring roll, and the unwinding tension measuring roll is connected with the PLC programmable logic controller (PLC).

Of the present utility model further arrange as follows:

Distance between the described adjacent slurry axle is identical.

Described head comprises beam of a loom and cord roller, is provided with measuring roller and total tension force measuring roll between beam of a loom and the cord roller, and measuring roller links to each other with the PLC programmable logic controller (PLC) with total tension force measuring roll.

Operation principle of the present utility model and beneficial effect are as follows:

Yarn goes out through each slurry spindle guide, behind unwinding tension measuring roll separately, again by cord roller, total tension force measuring roll, behind the measuring roller, batch on the beam of a loom through batching apparatus, wherein, the unwinding tension measuring roll is monitored in real time to the yarn tension on each slurry axle, and detected tension value is delivered to the PLC programmable logic controller (PLC), the PLC programmable logic controller (PLC) compares this tension value and initialization, according to the difference of calculating, the PLC programmable logic controller (PLC) sends instruction initiatively for the vector converter motor that drives the slurry axle, the vector converter motor changes rotating speed automatically according to instruction: when tension value during greater than initialization, the vector converter rotating speed of motor increases, otherwise then reduce, thereby make a sheet tension force remain near the preset value PLC programmable logic controller (PLC) automatically, vector converter motor and unwinding tension measuring roll have been formed close loop negative feedback, compare with simple total tension force measuring roll, certainty of measurement is higher, and it is more convenient to control; Because the configuration between the adjacent slurry axle has been adopted and respectively starched the mode that distance between axles equates, so also is not easy to produce kink, be high-quality long filament and the important basis of axle creation.

Adopt the utility model, can avoid that magnetic powder brake heating is serious, inhomogeneous, the shortcomings such as control accuracy is relatively poor, maintenance cost height of tension force control, make the unwinding tension of each slurry axle all can keep constant, mix the permanent tension force control of permanent linear speed of beam of a loom again, just reached the effect of high-quality and axle.

Wherein, beam of a loom is by main Electric Machine Control, and total tension force measuring roll is controlled by tension motor, and the slurry axle is then by the vector converter Electric Machine Control, and unwinding tension measuring roll etc. can not done set forth in detail herein with reference to existing equipment with concrete structure and the connected mode of PLC programmable logic controller (PLC).

The specific embodiment

The utility model warp rebeaming machine slurry axle unwinding tension control device in conjunction with Fig. 1, comprises head 8 and several slurry axles 2, and each slurry axle 2 all disposes independently unwinding tension measuring roll 1, and unwinding tension measuring roll 1 is connected with PLC programmable logic controller (PLC) 10.Wherein, the distance between the adjacent slurry axle 2 is identical, and head 8 comprises beam of a loom 9 and cord roller 3, is provided with measuring roller 5 and total tension force measuring roll 4 between beam of a loom 9 and the cord roller 3.

Yarn is derived through each slurry axle 2, behind unwinding tension measuring roll 1 separately, again by cord roller 3, total tension force measuring roll 4, behind the measuring roller 5, batch on the beam of a loom 9 through batching apparatus 6, wherein, yarn tension on 1 pair of each slurry axle 2 of unwinding tension measuring roll is monitored in real time, and detected tension value is delivered to PLC programmable logic controller (PLC) 10, PLC programmable logic controller (PLC) 10 compares this tension value and initialization, according to the difference of calculating, PLC programmable logic controller (PLC) 10 sends instruction initiatively for the vector converter motor that drives unwinding tension measuring roll 1, corresponding slurry axle 2 changes rotating speeds: when tension value during greater than initialization, corresponding slurry axle 2 rotating speeds increase, to reduce warp tension, otherwise then corresponding slurry axle 2 rotating speeds reduce, thereby make the silk sheet tension force on this slurry axle 2 remain near the preset value automatically, the PLC programmable logic controller (PLC), vector converter motor and unwinding tension measuring roll have been formed close loop negative feedback, compare with simple total tension force measuring roll 4, certainty of measurement is higher, and it is more convenient to control; Because therefore the mode that the configuration between the adjacent slurry axle 2 has adopted each slurry axle 2 spacing to equate also is not easy to produce kink, is that high-quality long filament and axle are created important basis.

In running, measuring roller 5 will detect the linear velocity of warp thread in real time, send it to PLC programmable logic controller (PLC) 10 in the lump, and 10 pairs of main motors of PLC programmable logic controller (PLC) are adjusted and controlled; And total tension force measuring roll 4 is also with the tension value of real-time detection lug yarn, and sends it to PLC programmable logic controller (PLC) 10, and 10 pairs of total tension force driven rollers 7 of PLC programmable logic controller (PLC) are adjusted and controlled.
