Abstract
The utility model aims at overcoming a defect of low elongation authenticity obtained when the elongation of slashing is tested in a method in the prior art through an existing test device, and provides a yarn fixed-length cutting device. The yarn fixed-length cutting device comprises a gland and a base, wherein a pressure head is arranged on a work surface of the gland, a through groove is arranged in a work surface of the base, the through groove is matched with the pressure head in shape and size,, and the base is fixedly connected with the gland through a bolt. When yarns are cut through the yarn fixed-length cutting device, what is needed is to comb the yarns and enable the yarns to straightly lie in the through groove, the gland is pressed and the yarns at a certain length can be cut off, repeated stretching of the yarns cannot be caused, and objective slashing elongation can be obtained.
Description
Technical field
The utility model relates to the method for testing of sizing fabric length growth rate and machine yarn length measuring capture device used.
Background technology
The sizing length growth rate is one of three large key process parameters of sizing operation, and it is tested and monitoring helps to carry out the technique adjustment, improves sizing quality.
The length that the sizing length growth rate refers to sizing after starching with respect to starching before the percent that increases of the length of warp thread, be expressed as:
(formula 1), wherein E is the sizing length growth rate, L
2Be sizing output length, L
1Be warp thread feeding length; Perhaps use
(formula 2), wherein V
2Be output line speed, V1 is the input end linear velocity.The length growth rate of sizing is by in the starching process, the elongation that warp thread is subject to serous infiltration, drying and the effect of warp-wise tension force produces, the height of length growth rate directly affects the intrinsic mechanical properties of the yarn such as the brute force, elasticity of sizing, thus end breakage and the weaving efficiency of road weaving process after impact.
Existing sizing test of elongation rate method is to adopt the direct method of measurement: measure respectively the linear velocity of output terminal roller and input end roller in the starching process, then compare computing by formula (2) and draw.Because the rotation of roller is to rely on that the friction when the operation drives with the yarn of its Surface Contact, and dynamic change, yarn can occur and all can cause the reasons such as friction force deficiency of roller and produce relative slippage between yarn and speed measuring roller in yarn tension in operational process, thereby cause roller tachometric survey error, make the length growth rate that obtains lose authenticity.
The utility model content
The purpose of this utility model is the low deficiency of length growth rate authenticity that obtains during for art methods and proving installation test sizing length growth rate, and a kind of machine yarn length measuring capture device is provided, and can conveniently intercept warp thread with this device, can not cause secondary extension to warp thread.
In order to realize above-mentioned technical purpose, the utility model adopts following technical scheme:
A kind of machine yarn length measuring capture device, comprise gland and base, be provided with pressure head at the working surface of described gland, be provided with groove at the working surface of described base, the geomery of described groove and described pressure head is complementary, and described base and described gland are bolted to connection;
Described base and described gland are rectangular parallelepiped, and mating surface both is complementary;
Be provided with the kerve that be arranged in parallel in the bottom of described groove, being complementary with described kerve is provided with the press strip that be arranged in parallel on described pressure head.
Adopt machine yarn length measuring capture device of the present utility model, simple in structure, easy to operate, during the intercepting yarn, only need the yarn combing is straight in groove, compress the yarn that gland can intercept certain-length, can not cause the stretching again of yarn, can obtain objective sizing length growth rate.

Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
As shown in Fig. 1-4, wherein Fig. 4 is the vertical view of the first embodiment base, is also the upward view of the first embodiment upper cover.The structure of preferred machine yarn length measuring capture device is as follows, it comprises gland 1 and base 5, is provided with pressure head 2 at the working surface of gland 1, is provided with groove 4 at the working surface of base 5, the geomery of groove 4 and pressure head 2 is complementary, and is provided with connecting hole 3 on base 5 and gland 1.During use, the yarn of needs interceptings is placed in groove 2 along the direction of groove 2 is parallel, extremely straight with the comb combing, gland 1 is pressed on base 5, put into bolt pre-connection base and upper cover in connecting hole, tentatively step up clamper, make pressure head tentatively compress yarn, make yarn keep stretching under some tension, tighten clamper under state parallel to each other.The cross section of preferred groove and pressure head is be complementary square or semicircle.Gland and base are rectangular parallelepiped and length A equates.Cut off unnecessary yarn bundle along servicing unit two ends with sharp blade.The cross section of preferred groove and pressure head is be complementary square or semicircle.Preferred gland and base are rectangular parallelepiped, and the surface of matching both is complementary, and are conducive to like this fixed length intercepting to yarn, facilitate blade cuts.
For a small amount of yarn of clamping better, be provided with kerve 7 in the bottom of groove 4, being complementary with this kerve 7 is provided with press strip 6 on pressure head.Like this, when amount of thread was few, yarn entered in kerve 7, compressed the interior yarn of kerve 7 by press strip 6, and because kerve 7 is little, so more be conducive to combing yarn to be intercepted.
