Abstract
The invention discloses a device for checking a spandex false twister, which is characterized in that: a novel device for checking false twisters is arranged in the checking of false twisters, and can test various spandex false twisters; meanwhile, the test is convenient and rapid; more importantly, a plurality of air outlet flues of the false twister are checked through airflows so as to guarantee the false twisting effect of the spandex false twister, uniform false twisting is performed when the spandex is subjected to false twisting, and good winding formation can be guaranteed when all airflows pass through the nozzle of the false twister. Therefore, bobbin forming quality is guaranteed, and wire coil tension is more uniform. The device for checking the spandex false twister comprises a twisting device, a pressure regulating device, a flow meter, a connecting device and a base, and has the advantages of simple manufacture, convenient operation and reliable performance.
Description
Technical field
The present invention relates to a kind of manufacturing technology and equipment of calibration equipment of novel spandex false twister, be specially a kind of calibration equipment of spandex false twister.
Background technology
Spandex softness and high resilience is not only next to the shin but also do not have restraint feeling when wearing has good wearability. be subjected to consumer's welcome deeply.In recent years, spandex not only is used for field of textiles, also is applied to fields such as industry, medical treatment, physical culture, and Application Areas constantly enlarges. and output also constantly increases.China's spandex production capacity continues to present the rise impetus, and at present, the spandex product of China has accounted for about about 70% of global spandex effective capacity.The competition of the Polyurethane Fibre Market of China increasingly sharpens after 2009.Therefore, continue to increase the innovation investment dynamics, reduce cost, improve product specification, develop new product, the technical merit that improves the quality and added value become the task of top priority of Enterprise's Sustainable Development.For adapting to the needs of this development, domestic enterprise is making extensive work aspect the transformation of urethane elastic fiber production technology and equipment.
In spandex was produced, dry spinning was main production method, and its output accounts for 80% of total output.Its process route is: the polyurethane spinning solution enters spinning shaft after measuring pump, spinneret orifice are extruded, under the circulating air effect, and the solvent in the stoste thread, constantly by the as-spun fibre inside behind thread and the preliminarily forming to surface diffusion into the surface, then evaporation is taken away by thermal air current, forms fiber.After spinning polymer solution thread entered spinning shaft, because the volatility of solvent is more intense, solvent left spinning poly compound thread and enters hot gas system.Strand begins to solidify, and along spinning the journey refinement gradually that is stretched, fiber is twisted by false twister when leaving the path, and the twist is transmitted to spinning Cheng Shangfang, and is pooled capital by boundling, and tow is compressed the vortex twisting of air in false twister.Because strand does not solidify as yet fully, form many chemical bond chalaza between the monofilament mutually, form the network knot, the coherent of fiber and elasticity are increased.Tow behind the boundling after oiling device oils, is wound into package through first godet roller again after columniform second godet roller of light face is adjusted tension force.In this process, the false twisting coiler device is one of crucial equipment.Because elastomeric polyurethane fiber is very big, recovery stress is bigger, and owing to the bad bobbin chimb that easily causes of false twisting, the silk tube is shaped bad when winding shaping.And the moulding of silk tube is bad, directly influences the quality of finished fiber on the one hand; Difficulty when causing unwinding owing to the inhomogeneous meeting of fiber tension in addition can not realize high-speed unwinding in the processing after weaving, more be prone to cacoplastic problem.In the use of spandex false twister, the air-flow of gas nozzle generally needs very homogeneous, and general false twister seldom or substantially carries out verification to all nozzle air currents after installation, can cause spandex silk false twisting heterogeneity like this, thread tension is irregular, and influence is used.
Some patents have been reported the improvement result to dry method spandex false twisting coiler device.The patent of Zhengzhou Zhongyuan Urethane Elastic Fibre Technology Co., Ltd.: a kind of spandex silk coiler device (patent No.: 200820068867.0), by at least two monomer winding mechanisms are stacked setting up and down, form a winder unit group, can be bigger utilize the space, adapt to multiple head spinning technology, make spandex output be able to obvious raising.The patent of Jiangsu Lu Jing: a kind of false twister (patent No.: 200420027228.1), the false twisting parts are reduced to the false twisting head, install by holder and false twisting body, have the lead-in groove of arcuation between the outside portion of false twisting head and the hole wall of thread eye, the hole wall of air channel and thread eye is tangent, and the aperture, air channel only is 0.2 millimeter.Spinning-in operation is simple, easy installation and removal, and the compressed air consumption is little, and the network knot homogeneity that forms through false twisting is good, and present this false twister generally uses.
But false twister is not carried out at present the relevant report of calibration equipment as yet relevant for how.How making false twister false twisting better effects if is very crucial technology.The use of false twister calibration technology and special-purpose calibration equipment is extremely important.
Summary of the invention
The technical problem to be solved in the present invention is the calibration equipment of a kind of spandex false twister of design.
The invention is characterized in by a kind of new type false twist cap calibration equipment is set in the verification of false twister, can test the spandex false twister of multiple class, test convenient and swift simultaneously, what is more important is regulated (pressure 0.1-1.0MP) by pressure, a plurality of air-out air channel at false twister, by air-flow (air flow rate 0.08-1.6L/MIN) all nozzles are carried out the air flow rate verification simultaneously under same pressure respectively, guaranteed the false twisting effect of spandex false twister, make the homogeneous false twisting when carrying out false twisting of spandex tow, like this, to all nozzle air currents by false twister by the time can guarantee that winding shaping is good, not only guarantee silk tube forming quality, and make silk volume tension force more even.
Spandex false twisting calibration equipment of the present invention comprises twisting apparatus, regulator, flowmeter, jockey, base.
False twister of the present invention is a kind of open type composite false twister of unique texture.The false twister calibration equipment is an assembly type.Different purposes is arranged respectively.Adjustable in length, false twister that can verification 1-64ENDS.
