Description

A kind of spandex feeding device

Technical field

The present invention relates to the spandex feeding device that uses in a kind of false twist texturing, specifically a kind of spandex feeding device that adopts false twist texturing machine to produce polyurethane covered yarn.

Background technology

Spandex has the synthetic fiber of high extension at break, low modulus and high elasticity response rate.Generally do not use separately, but mix in the fabric slightly.This fiber not only has rubber performance but also have the performance of fiber, is easy to broken end and flexible inhomogeneous when weaving.General spandex coating machine can only be with manufacturing polyurethane covered yarn than low velocity, and yield of unit time is low.

False twist texturing machine is a kind of post processing equipment of chemical-fibres filaments, precursor can be processed into the textured filament with low elasticity energy.

Usually wrap yarn is the composite yarn that forms with one or more staple fibres of spandex silk outsourcing (as cotton, hair, silk, fiber crops, wash, acrylic, viscose glue or various blend staple etc.) spinning.This composite yarn had both been given full play to the elastomeric property of spandex, had kept the surface characteristic that outer wrapping fiber provided again, was one of ideal yarn of the popular elastic fabric of present domestic production.

The spandex wrap yarn generally passes through RING SPINNING, open-end spinning, and eddy current spins, and static spins, friction spinning or special covered yarn spinning apparatus, but this kind equipment spins the staple fibre wrap yarn mostly at present, and spinning speed is lower, and production efficiency is not high.

In order to satisfy the demand that market increases year by year to the demand of long fiber spandex wrap yarn, Kai Fa the process equipment that adapts with it in the market, can only adopt two-step method to produce polyurethane covered yarn, be manufacturer must with polyamide filament (POY) finish on polyamide fibre or the polyester false twist texturing machine add bullet after, go up air tank covered yarn machine or mechanical wrap yarn machine and spandex silk again and be overmolding to bright and beautiful ammonia or wash the ammonia covering filament.The method of this polyurethane covered yarn of producing with two-step method must be equipped with two kinds of machineries for the requirement of manufacturer, exists the plant area occupancy big; Management cost, store place and the higher drawback of organization of production cost, and spandex has high extension at break, low modulus and high elasticity response rate, elasticity is big, easily broken first-class, general spandex coating machine can only be used than low velocity spinning polyurethane covered yarn, and yield of unit time is low, and production efficiency is low.For this reason, the applicant has proposed the patent application that a kind of name is called " utilizing the false twist texturing machine one-step method to make the method for the empty cladding of bright and beautiful ammonia plying " on September 21st, 2007, and the patent No. is: 200710132577.8.

Summary of the invention

Goal of the invention: the objective of the invention is to provide a kind of simple in structure, stable performance, can guarantee the spandex feeding device of the quality of finished silk in order on false twist texturing machine, to realize a step to produce polyurethane covered yarn.

Technical scheme: spandex feeding device of the present invention, comprise the roller and the bracing frame that are installed on the crossbeam, spandex spinning cake active type feeding thread guide mechanism is installed on bracing frame, this thread guide mechanism comprises handle, bobbin, bobbin shaft, spring; Handle is installed on the described bracing frame by bearing pin, the bobbin cup that is used for suit spandex spinning cake is at bobbin shaft, bobbin shaft is installed in the upper end of handle, and spring is connected between handle and the bracing frame, and the spandex spinning cake on the handle is pressed on the roller tightly from the top of roller.

The effect of above-mentioned thread guide mechanism mainly is the safe placement spandex silk bobbin of energy, the feeding of the spandex silk on the control spandex silk bobbin, guarantee that the spandex silk can be from unwinding smoothly on the spandex bobbin, make the spandex silk power of in the feeding process, reducing friction, guarantee stable drafting multiple.

The structure of spandex device and installation site directly have influence on the quality of POLYAMIDE YARNS, terylene thread and the spandex silk various polyurethane covered yarns after compound, and select suitable pressure just can guarantee that spandex closely contacts roller shaft all the time in operation process, guarantee the stable feeding ratio of spandex.Because pressure too conference causes the unwinding of spandex silk not exclusively to extrude bobbin, the too little spandex silk of pressure bobbin is beated easily, breaks away from roller, and feeding is unstable.

Beneficial effect: the present invention adapts at high-speed stretch yarn machine previous step making polyurethane covered yarn, enlarges the range of application of high-speed stretch yarn machine, can effectively improve the output of polyurethane covered yarn in conjunction with the fast characteristics of high-speed stretch yarn machine.

Description of drawings

Fig. 1 is a structural representation of the present invention.

Fig. 2 is the left TV structure schematic diagram of Fig. 1.

Fig. 3 is the partial enlarged drawing of Fig. 2.

The specific embodiment

As shown in the figure, every ingot spandex bracing frame 1 directly is installed on the rectangular tube crossbeam 3, and roller 2 changes the W2 laura structure into by original W1 laura structure, make spandex cake 4 in operation process gravity pressure to roller 2, prevent the spandex disengagement, the feeding that makes spandex guarantees the quality of finished silk than keeping stable.

Wherein bracing frame 1 is made up of

left bracing frame

5 and 6 two of right bracing frames and is connected on the rectangular tube 3.Same handle 16 also by about two form, couple together with left and right sidesing supporting frame respectively by bearing pin 9, copper sheathing 10, screw 11 and packing ring 12, and handle rotated flexibly.Extension spring bar 7 usefulness collars 8 are connected between left and right

sidesing supporting frame

5 and 6, and extension spring bar 14 usefulness collars 15 are connected between the handle of the left and right sides, and spring 13 hangs between extension spring bar 7 and the extension spring bar 14.Bobbin shaft 17 is installed in the upper end of handle 16, and bobbin 18 is enclosed within on the bobbin shaft 17.

Bracing frame 1 and roller 2 are installed on the rectangular tube crossbeam 3 simultaneously, and spandex spinning cake 4 makes spandex spinning cake 4 closely contact with roller 2 at the active force of spring 13, and when roller 2 rotated, spandex spinning cake 4 rotated with roller 2 the spandex silk is withdrawed from smoothly.

Illustrate below and on the polyamide fibre false twist texturing machine, utilize the present invention to realize that one-step method produces the method for the empty bag silk of bright and beautiful ammonia.This method is to have installed cover spandex feeding device of the present invention on original polyamide fibre machine additional, and second yarn cutter, second is visited the silk device that moves that a silk device, network equipment, middle auxiliary roller (W2x) and doubling use, by connector these devices are placed in the relatively reasonable position of polyamide fibre false twisting machine, guarantee the optimization of the Silk Road.This method may further comprise the steps:

A) polyamide fibre precursor (POY) is drawn by original silk rack, via first yarn cutter on the false twist texturing machine enter first feeding roller, through deformation hot box heating, again enter cooling device, false twister (comprising the turnover thread guide) and draw after, hold by suction gun.

B) the spandex silk is drawn via second yarn cutter, second a spy silk device by spandex feeding device, merging is held by suction gun with POLYAMIDE YARNS.

C) pass through middle roller and network nozzle device through two rhizoids that move on the middle roller after the middle porcelain spare of filament plate merges, during through the nozzle of interlace, air-flow with two rhizoid loopings together, form uniform node, again via the second auxiliary roller, by first a spy silk device, arrive the roller that oils, at last by the Wound-up roller coiling and molding.
