Description

Technical Field

[0001] The utility model relates to the technical field of warping machines, in particular to a warping machine which can prevent yarns from becoming loose. Background Art

[0002] Warping is the process of winding a certain number of warp yarns in parallel on a warp beam or weaving beam according to specified length and width. The warped warp yarns are used for sizing and drawing. Warping machines are essential production equipment for the production of warp knitted mesh fabrics.

[0003] After searching, the Chinese patent authorization announcement number CN 218404578 U discloses an anti-loosening high-efficiency warping machine. Although the compression spring will bounce the limit plate to drive the sliding rod to move toward the side of the winding warp shaft on the inner side of the sliding cylinder, and then press the compression rubber roller on the outer side of the winding warp shaft that has been wound with the yarn to prevent the yarn on the winding warp shaft from loosening, it is necessary to manually twist the positioning screw on the inner side of the threaded positioning sleeve to adjust the position between the compression rubber roller and the winding warp shaft, which makes the use and operation of the warping operation more cumbersome, increases the operating labor of the operators, and affects the convenience of the warping machine. Therefore, we propose a warping machine that can prevent the loosening of yarn. Utility Model Content

[0025] Working principle:

[0026] During use, the winding motor 4 is used to drive the winding warp shaft 2 to rotate, and the yarn is wound to the outside of the winding warp shaft 2. The adjusting motor 501 is used to drive the screw shaft 502 to rotate forward, driving the transmission seat 6 and the pressure roller 3 to move along the side close to the winding warp shaft 2, so that the pressure roller 3 presses the yarn on the winding warp shaft 2, and the spring 901 contracts. The yarn on the winding warp shaft 2 is in a compressed and clamped state to prevent the yarn on the winding warp shaft 2 from loosening. As the amount of the wound yarn on the winding warp shaft 2 increases, As the diameter of the winding warp shaft 2 increases, the spring 901 continues to contract, causing the pressure on the pressure sensor 601 generated by the retaining frame 7 to gradually increase. If the pressure monitored by the pressure sensor 601 is greater than the preset value, the controller 101 controls the adjusting motor 501 to drive the screw shaft 502 to rotate in the opposite direction, driving the transmission seat 6 and the pressure roller 3 to move to the other side, thereby quickly adjusting the position between the pressure roller 3 and the winding warp shaft 2, thereby ensuring that the winding warp shaft 2 rotates smoothly while keeping the wound yarn in a compressed and clamped state.
