Description

Fly frame prevent ripe bar accident elongation device

Technical field

This utility model relates to the parts of a kind of textile machine, and what relate in particular to a kind of fly frame prevents ripe bar accident elongation device.

Background technology

Weaving operation first has to distribute cotton, be exactly according to raw material special to spinning yarn quality requirement, by different cultivars, the place of production, lot number chopped fiber with suitable mixed method composition mixed material to yarn no matter in presentation quality or inherent quality, uniformity can be kept for a long time. Through the mixed material distributing cotton through shredding, remove impurity, mixing, carding machine carries out combing, loosens into ultimate fibre state and make the fiber carded sliver. Owing to resultant yarn requires that weight is uniform, generally will by 6 or 8 synthetic fibers carded slivers through twice to three time and close, make straightening of fibers parallel through drawing-off, preparing ripe bar. Ripe bar takes out that carefully to make it more stretch parallel being elongated by drawing-off, obtains becoming the sliver of rove. And fly frame is Spining Robot ribbon being made rove, its Main Function is drawing-off and twisting, and reeling roving is become certain package, to adapt to the mach requirement of spun yarn in the yarn process processed of synthetic fibers chopped fiber.

In cotton spinning production process, from drafting to spun yarn before not using super draft spinning frame, it is necessary to undertaken elongating by fly frame by yarn, draw and attenuate and be spun into rove, then rove is made satisfactory yarn by the draw twisting of spinning frame. The primary quality measure of rove has: Roving Elongation, weight unevenness, bar evenness CV% value, twist factor etc. Roving Elongation is the percent of the rove elongation in reeling roving process and the rove length ratio of front roller output. Being analyzed by experiment calculation, the impact of spinning evenness quality is closely-related by the size of Roving Elongation; Roving Elongation equally also affects weight unevenness and the roving twist of rove. Thus Roving Elongation plays conclusive effect in roving yarn quality, spin Roving Elongation general control during cotton and, at 1%--2.5%, control at-1.5%--+1.5% when spinning chemical fibre. And rove is weak twist product, the spun rove of existing fly frame, by easily producing unexpected elongation after tension force, makes the weight unevenness of rove and yarn unevenness increase, largely effects on the performance of enterprises.

Utility model content

The purpose of this utility model be in that provide a kind of fly frame rational in infrastructure, easy for installation, applied widely prevent ripe bar accident elongation device, this device is effectively reduced misdraft and the friction to cotton sliver, and being conducive to the improvement of later stage operation yarn quality, resultant yarn filoplume also reduces relatively.

For reaching above-mentioned purpose, this utility model fly frame prevent ripe bar accident elongation device, including fly frame and the guide strip rack being disposed thereon, described guide strip rack is provided with some sprocket wheels and some guide strip rollers, some guide strip rollers be arranged below some cylinders, each guide strip roller is provided with sliver separator; Described some sprocket wheels are connected by chain, described some sprocket wheels are provided with dynamic pickup, fly frame is additionally provided with bobbin dynamic pickup, dynamic pickup is all connected with the input of PLC through wire with bobbin dynamic pickup, and the outfan of PLC is connected to main frame and alarm lamp.

In technique scheme, owing to passing through to arrange dynamic pickup on some sprocket wheels, and bobbin dynamic pickup is set on fly frame, so when occurring chain stuck or release failure, sprocket wheel stall causes that guide strip roller does not turn, dynamic pickup no signal exports, but now main frame is still in operating, bobbin dynamic pickup still has turn signal, both signals are inconsistent, and namely PLC stops main frame operating, thus reducing guide strip roller misdraft and the friction to cotton sliver, being conducive to the improvement of rear operation yarn quality, resultant yarn filoplume also reduces relatively; Meanwhile, alarm lamp is lighted, and spinner can supervise the machine work of repairing to keep in repair after finding.

This utility model has the advantages that input cost is little, easy for installation, applied widely, can match with multiple fly frame equipment, have good practicality.

Accompanying drawing explanation

Fig. 1 be this utility model fly frame prevent ripe bar accident elongation device structural representation.

Detailed description of the invention

Below in conjunction with accompanying drawing, the ripe bar accident elongation device that prevents of this utility model fly frame is described in further detail.

As seen from Figure 1, this utility model fly frame prevent ripe bar accident elongation device, including fly frame 1 and the guide strip rack 2 being disposed thereon, described guide strip rack 2 is provided with some sprocket wheels 3 and some guide strip rollers 4, some guide strip rollers 4 be arranged below some cylinders 5, each guide strip roller 4 is provided with sliver separator 6; Described some sprocket wheels 3 are connected by chain 7, described some sprocket wheels 3 are provided with dynamic pickup 31, fly frame 1 is additionally provided with bobbin dynamic pickup 11, dynamic pickup 31 is all connected through the input of wire with PLC 8 with bobbin dynamic pickup 11, and the outfan of PLC 8 is connected to main frame 9 and alarm lamp 10.

During utility model works, owing to fly frame 1 is made up of feeding, drawing-off, twisting, winding shaping mechanism, wherein intake mechanism guide strip rack 2 is to be drawn in bar cylinder 5 by ripe bar 11, drafter is entered through sliver separator 6, guide strip roller 4 and sliver loudspeaker, the sliver of drafted one-tenth regulation thickness, is sent by front traction roller, by flier, sliver twisting is become rove, on boundless or spool, thus completing the elongation of fly frame 1, drawing and attenuating the task of being spun into rove. complete in the process of task at fly frame 1, owing to being provided with dynamic pickup 31 on some sprocket wheels 3, when main frame 9 rotates, sprocket wheel 3 synchronous axial system signal monitored by dynamic pickup 31, access PLC 8 input with the turn signal of bobbin dynamic pickup 11 and compare monitoring: when occurring chain 7 stuck or release failure, sprocket wheel 3 stops operating, guide strip roller 4 is caused also to stop operating, dynamic pickup 31 no signal exports, but at this moment main frame 9 is still in operating, bobbin dynamic pickup 11 still has turn signal, the signal of dynamic pickup 31 and bobbin dynamic pickup 11 is inconsistent, namely PLC 8 outfan stops main frame 9 and operates, alarm lamp 10 is lighted simultaneously, spinner just can supervise the machine work of repairing to keep in repair after finding, avoid producing rove.

This utility model has the advantages that input cost is little, easy for installation, applied widely, can match with multiple fly frame equipment, guide strip roller misdraft can be reduced equally, thus reducing the friction to cotton sliver, being conducive to the improvement of rear operation yarn quality, resultant yarn filoplume also reduces relatively. It was verified that the ripe bar accident elongation device that prevents of fly frame is feasible to improving roving yarn quality and preventing quality accident, there is good practicality.

Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described. Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model.
