The invention discloses a yarn constant-pressure tensioning device of geotechnical cloth. Multiple counterweight blocks are connected onto a supporting rod from top to bottom in a threaded mode, a left downward supporting plate and a right downward supporting plate are arranged at the lower end of a horizontal plate, and the lower ends of the supporting plates are fixed onto a warp knitting machine; yarn is arranged at the lower end of a press rod, and the left end and the right end of the yarn wind from the upper sides of rotation rods on the corresponding sides respectively. During use, theyarn penetrates in from the upper side of the rotation rod on one side, winds form the lower side of the press rod and penetrates out from the upper side of the other rotation rod, so that the pressure rod applies pressure on the yarn, the pressure comes from the gravity of the press rod, a sliding block and the counterweight blocks, the gravity is constant, and thus the applied force is constant;when the yarn is loose, the press rod drives the sliding block to move downward, tensioning is guaranteed, and when the force intensity is high, the press rod moves upward, then the pressure is constant, the tensioning degree is guaranteed, and the production quality of the subsequent geotechnical cloth is guaranteed; when the pressure of the whole device is changed, adjustment can be conducted by changing the number of the counterweight blocks, and the yarn constant-pressure tensioning device is more convenient to use.
Description
technical field [0001] The invention relates to the technical field of geotextile tensioning, in particular to a yarn constant pressure tensioning device for geotextiles. Background technique [0002] Because the fabrics woven by warp knitting machines have different patterns, different raw materials, different starting speeds, etc., the warp let-off amount of the required yarns is also different, so the tension control of the warp knitting machine is a very important link in the weaving process. During the weaving process of the warp knitting machine, the yarn is fed into the warp knitting machine for weaving. In the process of weaving the fabric, the tension on the yarn is also constantly changing, so it is necessary to constantly adjust the tension so that the tension meets the weaving requirements. There are also many adjustment devices in the market, most of which are squeezed by springs. However, the spring force is related to the stretching length. When the yarn tight...
