Description
Technical Field
The utility model relates to a cotton yarn detects technical field, specifically indicates a cotton yarn detects uses single yarn strength machine.
Background
The tensile strength and the non-uniformity of the root yarn are one of main quality indexes representing the use value of the yarn, and an electronic single yarn strength instrument is an instrument for evaluating technical indexes of tensile properties of the yarn, fiber filaments and the like. The single yarn strength machine is used for testing the breaking strength and the elongation of single yarn and fiber pure-spun or blended yarn of various cotton, wool, hemp, silk, chemical fiber and core-spun yarns. The electronic single-yarn strength tester is controlled by a single chip microcomputer, a high-end tester can be connected with a computer, and mechanical data of the yarns are recorded through a sensor. In use, a predetermined sample is taken, held by a chuck of the apparatus, pulled at a predetermined speed until it is broken, and the breaking strength and elongation at break are recorded.
The single yarn strength machine of first stage is mostly two chucks about, goes up the chuck fixed, and lower chuck carries out linear motion through drive mechanism to the yarn is elongated, realizes the test of yarn. However, only the lower jaw moves, so that the traction force received by the yarn is concentrated on the lower part, which causes a large force on one end of the yarn and a break at first, thus generating a measurement error; and for yarns, the single-end stretching operation is not only low in stability, but also low in testing efficiency.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to overcome above technical defect, provide a cotton yarn detects uses single yarn strength machine that operates steadily, detects accuracy, operating efficiency is high.
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: this design cotton yarn detects with single yarn strength machine, include the frame and fix drive mechanism, fixture, force sensor and the treater in the frame, force sensor locates on the fixture, treater control drive mechanism and receipt force sensor's data, drive mechanism includes two-way lead screw, ball slip table, shaft coupling, driving motor and supporting seat, two-way lead screw passes through the supporting seat and installs in the frame, two ball slip tables are installed respectively on two sections opposite screw threads of two-way lead screw, the two-way lead screw of shaft coupling coaxial coupling is passed through in driving motor's pivot, fixture includes chuck and lower chuck, it reaches chuck fixed mounting respectively on two ball slip tables to go up the chuck. The design utilizes the principle that a ball sliding table on a bidirectional screw can synchronously move in a reverse linear mode when the bidirectional screw rotates, and a chuck is installed on the ball sliding table, so that the spinning yarns can be stretched at two ends simultaneously.
Furthermore, the ball sliding tables are symmetrically arranged on the bidirectional screw rod by taking a perpendicular bisector of the axis of the bidirectional screw rod as a center line.
Further, the driving motor is a stepping motor. The accuracy of each step of the stepping motor is three to five percent, and the error of one step is not accumulated to the next step, so that the stepping motor has better position accuracy and motion repeatability, and has excellent start-stop and reverse response.
Furthermore, a graduated scale is arranged on the rack and is parallel to the axis of the bidirectional screw rod.
Further, all be equipped with the laser lamp on going up chuck and the lower chuck, the laser lamp is light direction perpendicular to the scale setting, just the light of laser lamp can pass the scale. Through the addition of the graduated scale and the laser lamp, the specific data of the experiment can be visually observed and recorded.
After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the utility model utilizes the bidirectional screw as the transmission shaft, and utilizes the principle that the rotation of the bidirectional screw can lead the ball sliding table to move oppositely, and simultaneously stretches the two ends of the cotton yarn, thereby leading the stress of the cotton yarn to be even and leading the test result to be accurate; meanwhile, because the upper chuck and the lower chuck move simultaneously, the stroke of the upper chuck and the lower chuck is twice that of a common strength tester, the testing time is shortened, and the use efficiency is high.
