Detailed Description

The towel loom combined tension adjusting device of the present invention will be described in detail below with reference to the accompanying drawings.

Example one

As shown in fig. 1 to 3, the combined tension adjusting device of the towel loom of the present invention includes a left frame 1, a right frame 2, a driving beam assembly 3, a guide shaft 4, a pressure spring assembly 5 and a tension spring assembly 6, wherein the driving beam assembly 3 is disposed between the left frame and the right frame, the guide shaft 4 is disposed above the driving beam assembly, the driving beam assembly is provided with a plurality of pressure spring assemblies 5, and the inner sides of the left frame and the right frame corresponding to each other are respectively provided with the tension spring assembly 5. And the side wall of the left frame or the right frame is provided with an inductor positioning frame for fixing the tension inductor.

The driving beam assembly 3 comprises a fixed shaft 3-1, a swinging shaft 3-2 and a swinging shaft mounting plate 3-3, one end of the fixed shaft 3-1 is connected with the left frame 1, the other end of the fixed shaft is connected with the right frame 2, and the swinging shaft is connected with the fixed shaft 3-1 through a plurality of swinging shaft mounting plates 3-3. One end of the swing shaft mounting plate is sleeved with the fixed shaft, and the other end of the swing shaft mounting plate is sleeved with the swing shaft 3-2.

As shown in fig. 3, the pressure spring assembly 5 includes a pressure spring 5-1, a U-shaped bolt 5-2, a fixing plate 5-3 and a tension rod 5-4, one end of the pressure spring 5-1 is connected with the fixing plate 5-3, the other end is connected with the tension rod 5-4, the U-shaped bolt 5-2 is connected with the fixing plate 5-3, and the U-shaped bolt 5-3 is sleeved with the fixing shaft 3-1 of the driving beam assembly. The tension rod is provided with a U-shaped groove, the front end of the pressure spring is sleeved with the U-shaped groove on the tension rod through U-shaped nylon, and the tension rod can be prevented from moving back and forth through positioning of the U-shaped groove and the U-shaped groove.

The compression spring 5-1 faces the rear side of the loom, and the compression spring is twisted through the primary tension of the pile warp yarns, so that the position of the compression spring can be transversely adjusted according to the aesthetic property of the pile loops and the requirement on the tension of the edge of the fabric in the weaving process of the loom, and unnecessary time is not wasted.

The tension spring assembly 6 comprises a tension spring 6-1, a support arm 6-2 and an adjusting bolt 6-3, one end of the tension spring 6-1 is vertically connected with the support arm 6-2, the other end of the tension spring is connected with the adjusting bolt, the support arm 6-2 is fixedly connected with a fixed shaft 3-1 of the driving beam, and the adjusting bolt is rotatably connected with a fixed block on the side wall of the left frame or the right frame, so that no interference exists in the working state. The tension spring 6-1 is designed to have initial tension, then gives static tension, and can adjust the tension of the tension spring by rotating the adjusting bolt. The tension spring 6-1 is parallel to the direction of the last yarn, when the yarn tension adjusting device works, the yarn is stressed, the pressure spring 5-1 is twisted, the tension spring stretches, and the force is transmitted to the yarn tension adjusting system in the first time. The diameter of the spring wire of the pressure spring 5-1 is smaller than that of the spring wire of the tension spring 6-1.

As shown in the yarn trend A9 of FIG. 2, the yarn firstly rounds a guide shaft 4, then passes through the upper side of a fixed shaft 3-1, then presses a tension rod 5-4, then rounds a swinging shaft 3-2 and forwards to a weaving opening, a certain tension is given to the yarn before the loom works, the yarn firstly twists a compression spring 5-1, and the swinging shaft 3-2 is forced to drive the tension spring to move after a certain twisting amount. In the working state of the loom and the terry raising stage, the instant stress of the warp yarns is increased, the torsion of the pressure spring and the tension of the tension spring are increased, the earliest reaction of the pressure spring is still realized, then the tension spring 6-1 acts, the pressure spring is slowly twisted in the tension spring stretching stage, the pressure spring and the tension spring are matched with each other to bear the stress, so that the sudden tension change of the yarns cannot occur, and the yarns are not damaged in the terry. The tension spring of the loom is firstly reacted in the resetting stage, the pressure spring is synchronously reset in the resetting stage, the speed of the tension spring is high when the tension spring is reset, then the intermediate pressure spring is reset, so that the drastic change of the yarn tension when the tension spring is reset can be reduced, and the pressure spring still has certain action after the tension spring is reset, but is soft, so that the stable yarn tension is ensured.
