Abstract
The utility model discloses a jacquard yarn guide needle test system. The jacquard yarn guide needle test system is characterized in that a jacquard yarn guide needle is mounted on a jacquard needle block; a yarn guide hole allowing yarn unwound from a yarn supply barrel to penetrate is formed in the lower end of the jacquard yarn guide needle; and the jacquard yarn guide needle is driven by a jacquard control system to drive the yarn penetrating into the yarn guide hole to perform lateral deviation movement. The test system comprises a high-speed video record analysis system which is used for shooting deviation movement images of the jacquard yarn guide needle and performing data analysis on the images and a yarn tension device for applying tension force on the yarn, wherein the high-speed video record analysis system comprises a high-speed camera with a speed of higher than 3,000 frames/s and a microprocessor; and the yarn tension device comprises a plurality of weights, and a yarn barrel is rotationally mounted on a rack. With the adoption of the jacquard yarn guide needle test system, the deviation time of the jacquard yarn guide needle can be tested under the condition of certain yarn tension, the system is closer to the actual use condition of the jacquard yarn guide needle the maximum extent, meanwhile, the performance of a jacquard control system and the deviation force of the jacquard yarn guide needle can be indirectly reflected, and the test cost is low.
Description
Technical field
The utility model relates to a kind of for testing the test macro of warp knitting machine parts performance, particularly relate to the test macro that judges the piezoelectric ceramics Jacquard sley point performance using on jacquard warp.
Background technology
Warp knitting machine manufacturer is in the time selecting domestic Jacquard sley point, if Jacquard sley point is not installed on jacquard warp and is woven into while enclosing motion, generally cannot judge the good of its actual serviceability, and verify Jacquard sley point performance on jacquard warp time, high cost, installation complexity, and very easily Jacquard sley point is caused to damage, and therefore, in the urgent need to a kind of test macro of not going up machine and just can judging Jacquard sley point performance.
Summary of the invention
The technical problems to be solved in the utility model is to provide so a kind of Jacquard sley point test macro, can test the shift time of the Jacquard sley point under certain yarn tension condition by this test macro, press close to the full extent the actual service condition of Jacquard sley point, this test macro can reflect the size of the performance of Jacquard control system and the biasing force of Jacquard sley point indirectly simultaneously, testing cost is low simultaneously, and test condition requires low.
For solving the problems of the technologies described above, the utility model adopts so a kind of Jacquard sley point test macro, described Jacquard sley point is arranged on jacquard needle block, the lower end of Jacquard sley point is provided with the thread guide eyelet passing for the yarn that on yarn cylinder, unwinding is got off, Jacquard sley point is driven and is driven the yarn that penetrates thread guide eyelet to do together lateral shift motion by Jacquard control system, and this test macro comprises offset movement image by taking Jacquard sley point and image is carried out the high-speed camera record analysis system of data analysis and yarn applied to the thread tension device of tension force.
As a kind of preferred embodiment of the present utility model, described high-speed camera record analysis system comprises high-speed camera more than 3000 frames/s and is arranged on the microprocessor that on high-speed camera, image is carried out data analysis, described thread tension device is made up of several counterweights, described counterweight is suspended on the yarn bottom that unwinding is got off from yarn cylinder, and described yarn cylinder is arranged in frame rotationally.
Adopt after said structure, the utlity model has following beneficial effect:
The utility model can be put analysis slowly to the image of taking, thereby obtains shift time, the biasing force size of Jacquard sley point and the tension range adapting to.
During not containing yarn, by testing the shift time of Jacquard sley point, thereby analyze the quality of Jacquard control system response.
In band yarn when test, can test out the shift time of Jacquard sley point under some tension condition, thereby extrapolate Jacquard sley point and Jacquard control system can be suitable for the highest warp knitting machine machine speed.
Can judge by test data before use the performance of Jacquard sley point, thereby select optimum Jacquard sley point.
