Description

Technical Field

[0001] The invention relates to the technical field of textile machines, in particular to a yarn tensioning device for yarn weaving and an adjusting method. Background Art

[0002] Yarn tension plays a vital role in the spinning process. Appropriate yarn tension can maintain the stability of spinning and ensure that the yarn does not break or form defects during processing. If the yarn tension is too large, the yarn may break due to excessive tensile force, resulting in production interruption and deterioration of yarn quality. On the contrary, if the yarn tension is too small, the yarn may be too loose and prone to yarn defects, which also affects the quality and output of the yarn. Therefore, when spinning yarn, it is usually necessary to pass the yarn through the corresponding holes of the tensioning device in turn to adjust the yarn tension. However, when the yarn is connected to the tensioning device, the process of the yarn passing through the holes is relatively time-consuming, making it inconvenient to adjust the yarn tension.

[0003] The patent document with announcement number CN110371783B discloses a variable-direction yarn textile operation guide tensioning device and method, including a base plate, a change-direction pulley rod, an annular slide groove, a connecting column, a connecting disk, an anti-loosening device and a rotating disk, wherein an annular slide groove is provided on the base plate, and the annular slide groove is connected to the change-direction pulley rod by a sliding fit, a connecting column is installed in the middle of the base plate, and the connecting column is located between the two change-direction pulley rods, and a connecting disk is installed on the upper end of the connecting column, and an anti-loosening device is evenly arranged on the connecting disk along its circumference, and a rotating disk is arranged on the upper end of the connecting disk, and the yarn is synchronously stretched open by the anti-loosening device, thereby changing the winding length of the yarn, so that the yarn is in a taut state as a whole, and the conveying direction of the yarn is changed by adjusting the position of the two change-direction pulley rods, thereby reducing the friction generated during the change-direction conveying of the yarn, and reducing the wear degree of the yarn, but the patent still has the following problems in actual use:

[0004] The tensioning device connects the yarn to the tensioning device by passing the yarn through the gap in the middle of the arc frame in sequence, which makes the connection process of the yarn and the tensioning device time-consuming, reduces the efficiency of adjusting the yarn tension, and affects the efficiency of yarn spinning. At the same time, when the yarn tension is too large during the adjustment process, the tensioning device is difficult to buffer the tension of the yarn, which makes the yarn easy to break during adjustment.

9. A yarn tensioning device and adjustment method for yarn weaving according to claim 1, characterized in that: The yarn tensioning device and adjustment method for yarn weaving as claimed in claim 8 are used, and the steps of using the method are as follows: Step 1: Align the yarn with the guide groove (206) so that the yarn falls into the guide groove (206), and push the limit spring (203) to shrink in the limit groove (202) inside the guide seat (201) by pressing the limit block (204), so that the guide groove (206) is completely exposed, so that the yarn passes through the guide groove (206) and enters the guide ring (205), thereby positioning the yarn position, reducing the steps of passing the yarn through the hole, and making it more convenient to adjust the yarn tension. At this time, the limit block (204) is reset and the lower end of the guide groove (206) is closed to prevent the yarn from passing through the guide groove (206) and separating from the guide ring (205), and at the same time prevent the lower end of the guide groove (206) from causing wear to the yarn, thereby achieving the effect of improving the yarn guiding stability; Step 2: By pressing the pressing plates (301) on both sides of the base (1) to shrink toward the middle, the pressing plates (301) push the connecting seats (305) at both ends to move. At this time, the moving groove (306) on one side of the connecting seat (305) slides on the fixed seat (309) through the moving rod (307), and the return spring (308) shrinks to guide the moving direction of the connecting seat (305). At the same time, the positioning block (304) pushes the positioning spring (303) to shrink into the shrinking groove (302), so that the positioning block (304) is separated from the positioning groove (310). At this time, the connecting seat (305) drives the fixed rotating shaft (401) to move. The tensioning wheel (407) at the end of the rod (402) moves in the direction of the connection seat (305), so that the two staggered tensioning wheels (407) are unfolded, and the connection groove (408) below the tensioning wheel (407) is rotated, and then the two tensioning wheels (407) fall on both sides of the center line with the two guide rings (205) as end points, so that the gap between the guide ring (205) and the tensioning wheel (407) forms a straight line state, which facilitates the installation of the yarn in the tensioning wheel (407) by pressing directly, and the support seat (409) in the middle of the tensioning wheel (407) supports the yarn to prevent the yarn from falling off from the middle of the tensioning wheel (407); Step 3: Align one end of the middle yarn passing through the tensioning wheel (407) with the guide groove (206) again, and complete the connection between the yarn and the tensioning device by pressing the limit block (204). Then, when the pressing plate (301) is released, the connecting seat (305) is reset under the action of the reset spring (308) pushing the fixed seat (309), and the positioning block (304) is engaged with the positioning groove (310) to form a positioning. At the same time, the tensioning wheel (407) is reset to form a staggered effect, so that the yarn is tightened; Step 4: Rotate the threaded rod (413) so that the block (416) outside the threaded rod (413) pushes the telescopic spring (415) to shrink into the give way groove (414), so that the block (416) is separated from the groove (417), and after one rotation, the block (416) is engaged with the groove (417) again, so that the number of rotations of the threaded rod (413) is recorded, so that the tension of the yarn can be uniformly adjusted during weaving, and at the same time, the threaded rod (413) drives the moving shaft (411) to slide in the sliding groove (412), so that the moving shaft (411) drives the sliding rotating rod (410) rotates at the sliding shaft (406), and the fixed rotating rod (402) rotates at the fixed shaft (401), thereby adjusting the staggered position of the tensioning wheel (407) at the end of the fixed rotating rod (402), thereby adjusting the yarn tension, and when the yarn tension is too large, the yarn will push the tensioning wheel (407) to shrink toward the middle, and the fixed rotating rod (402) pushes the buffer plate (404) to slide in the buffer groove (403) through the sliding shaft (406), and buffers the tension through the buffer spring (405), thereby reducing the possibility of yarn breakage.
