Abstract
The utility model discloses a cord pendency degree meter, relating to a special measuring device of cord pendency degree meter. The cord pendency degree meter comprises a twist multiplier meter whose bottom plating 1 is provided with a sledge 2, a calibrator reading device which is engaged with a guiding rail 3 in a tooth shape. The guiding rail 3 in a tooth shape is the cross beam of the sledge 2 which can slide in the concave groove of the bottom plating 1. The reading device which is engaged with the guiding rail 3 can freely displace along the guiding rail 3 in a tooth shape. A large needle gear connecting bar 4 of the reading device is provided with a rotary gear 5 on which a tensile fine adjustment 6 is engaged. The top part of the reading device is provided with a left clamping head 7 whose height is equal to the height of a right clamping head 8 of the twist multiplier meter. The cord pendency degree meter of the utility model being easy to operate is professionally designed. With the arrangement of the tensile fine adjustment 6, the cord pendency degree meter can control the elastic deformation of the cord by the known and given tensile force. As a result, the reproducibility, the comparability of the experimental result, and the accuracy degree of the measurement result is improved, whichhighly decreases the individual errors and improves the labor efficiency.
Description
Technical field
Cotton rope hangs sight for sag, relates to the specialized equipment that cotton rope degree of dangling is measured.
Background technology
The degree of dangling of cotton rope is after unit length cotton rope backtwisting becomes single thread, the length difference of the longest yarn and shorter yarn.It is an important technology index of weighing even tension between the cotton rope single thread, and it relates to the strength retention ratio behind single thread and the rope.
At present, the specialized equipment that does not also have cotton rope degree of dangling to measure.The measurement of existing cotton rope degree of dangling, be with the cotton rope sample backtwisting of certain-length (long) as 1 meter, put twist with the fingers into single pencil after, make the cotton rope two ends be free state, with the naked eye judge the longest yarn and shorter yarn, use Steel Ruler again, hand dipping goes out their length, calculates their length difference.The manual measurement method of this backwardness, workload is big, and efficient is low, and measuring accuracy is poor, and individual error is big, is difficult to satisfy the requirement of international advanced standard.
Summary of the invention
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, propose the outstanding sight for sag of a kind of cotton rope, it is with the reading device of former twist measuring instrument and thicknessmeter, makes up and improves, reduce individual measuring error effectively, measured the degree of dangling of cotton rope comparatively accurately.
Technical solution of the present utility model is: it comprises twist tester and thickness gauge reading device, the thickness gauge reading device is engaged on the profile of tooth guide rail 3, it is characterized in that: on the base plate 1 of twist tester, balladeur train 2 is housed, profile of tooth guide rail 3 in the thickness gauge is the crossbeam of balladeur train 2, balladeur train 2 can slide in the groove of base plate 1, reading device is engaged on the profile of tooth guide rail 3 by transmission gear 12, and can be along the 3 free displacements of profile of tooth guide rail, on the large needle gear connecting rod 4 of reading device swing pinion 5 is housed, tension force micro actuator 6 is engaged on the swing pinion 5, the top of reading device is provided with left chuck 7, and its height is corresponding with the right chuck 8 on the twist tester.
Profile of tooth guide rail 3 is designed to square, can prevent the rotation of the reading device of interlock on it.
The below of the left chuck 7 at reading device top is provided with flexible resilient pad 9, can protect by yarn clipping line sample injury-free.
The outstanding sight for sag of the cotton rope that adopts the utility model scheme to make, reasonable in design, easy to operate.By the setting of tension force micro actuator, with given known tension force, control the elastic shrinkage of cotton rope, improve the reappearance and the comparability of experimental result, and increased the degree of accuracy of measurement result, significantly reduced individual measuring error, improved efficiency.
Description of drawings
Fig. 1 is for being the utility model structural representation;
Fig. 2 is former cotton rope twist tester structural representation;
Fig. 3 is that the thicknessmeter reading device cooperates synoptic diagram with the profile of tooth guide rail;
Fig. 4 is a reading device inner structure synoptic diagram.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Be installed on the foursquare profile of tooth guide rail 3 with the transmission gear 12 in the desk-top thicknessmeter of commercially available percentage (production of the Shanghai six water chestnut instrument plants) reading device, with profile of tooth guide rail 3 is that crossbeam makes balladeur train 2, balladeur train 2 is placed in the groove of twist instrument (the hand cotton rope twist of Y321 type instrument) base plate 1, makes the left chuck 7 at reading device top and the right chuck on the twist tester 8 high together.Regulating between the left and right chuck distance is zero.Tension force micro actuator 6 is engaged on the swing pinion 5, and swing pinion 5 is installed on the connecting rod 4 of the big pin gear in the reading device.Tension force micro actuator 6 moves reading device by swing pinion 5 on profile of tooth guide rail 3, when regulating cotton rope sample tension force with tension force micro actuator 6, can be easy to tell shorter yarn.Not impaired for protection cotton rope sample, below left chuck 7, rubber sheet gasket 9 is housed.
The outstanding sight for sag using method of this cotton rope is as follows:
1, the cotton rope sample is fixed on the right chuck 8 of twist instrument, measures the certain-length cotton rope and make a call to a latch closure, it is walked around pulley 10 and links up with 11 and link to each other, add the tension force counterweight according to the line density of cotton rope.
2, mobile reading device is in the right-hand member basic point place of profile of tooth guide rail 3, and mobile balladeur train 2 is to a certain reading of the rule place of twist tester base plate 1.
3, with the cotton rope backtwisting, with fine needle every of cotton rope single bundle is not separately had and to intersect, rotation tension force micro actuator 6 makes shorter yarn be in tensioned state, and all the other yarns are loose.Successively shorter yarn is cut off, directly stayed a yarn the longest, read the shortest and the length of long yarn.
4, calculate sample cotton rope degree of dangling by cotton rope degree of dangling computing formula.
