One end of the raising swing arm 102 is hinged to the raising support 101 . The raising swing arm 102 is driven by the cloth moving raising motor to generate cloth moving motion, which is the basic motion of the cloth moving towel loom, which belongs to the prior art and will not be described in detail here. The transfer rocker arm 107 is arranged on the left wall panel 4 , the fluffing swing arm 102 is connected with one end of the transfer rocker arm 107 through the first link 105 , and the other end of the transfer rocker arm 107 is connected by the second link 110 It is connected with one end of the swing shaft driving arm 112 , and the other end of the swing shaft driving arm 112 is fixedly connected with the tension swing shaft 113 .

The pendulum rod fixing clip 114 is lighter in weight, and the pendulum rod 115 is a light-weight thin-walled tube, which reduces the mass inertia of the pendulum piece to facilitate high-speed operation. It can be seen from the figure that the swing direction of the 115 swing bar is the same as the swing direction of the raising swing arm 102, that is, when the raising swing arm 102 swings forward, the swing bar also follows forward, and when the raising swing arm swings backward The rod also follows backwards.

The force exerted on the supporting pendulum shaft 205 is transmitted to the tension servo motor 209 through the transmission mechanism and reaches a balance. Through the active control of the torque of the tension servo motor 209, the control of the different tensions of the warp yarns on the supporting pendulum shaft 205 is realized to meet the requirements of weaving.

The wool warp tension buffer device 3 is laterally arranged between the support swing shaft 205 and the tension swing shaft 113 , and its two ends are fixedly connected to the two wall panels 4 respectively. The wool warp tension buffer device 3 includes a buffer support shaft 302, a buffer sleeve 303 and a buffer pressure plate 304. The buffer support shaft 302 is arranged in parallel with the support pendulum shaft 205, and its left and right ends pass through the buffer support 301 and the two walls respectively. The plates 4 are fixedly connected.

The buffer sleeve 303 is a cylinder formed by rolling a rectangular thin plate, and is sleeved on the outside of the buffer support shaft 302 . On the side wall, there are several buffer pressing plates 304, which are arranged in sequence along the axial direction of the buffer support shaft 302, and the two ends of the buffer sleeve 303 are pressed and locked on the surface of the buffer support shaft 302 by screws.

The buffer sleeve 303 and the buffer support shaft 302 form an inscribed connection state, and a crescent-shaped deformation cavity is formed between the inner wall of the buffer sleeve 303 and the buffer support shaft 302, and the buffer sleeve 303 is far from the buffer support. When pressure is applied on the shaft side, the spring plate buffer can be realized by the deformation of the buffer sleeve 303. When a large pressure is applied, the buffer sleeve 303 deforms greatly and can contact the outer surface of the buffer fulcrum, so that the tension of the hair warp can be rapidly increased . It can be seen from FIG. 2 or FIG. 4 that the position of the buffer sleeve 303 is relatively close to the front of the loom, which can increase the wrapping angle of the warp and improve the effect of tension buffering.

It can be seen from FIG. 2 that the wool warp yarns go from the wool warp weaving shaft first through the support swing shaft 205, then through the buffer sleeve 303 to the tension swing shaft 113, and then sent to the front of the loom by the swing rod 115. The supporting pendulum shaft 205 plays the role of guiding and positioning the warp, the buffer sleeve 303 is closer to the front of the loom, and the warp forms a larger wrap angle on the buffer sleeve 303, and also increases the wrap angle of the warp on the tension pendulum shaft 113, These are helpful for precise control of tension sensing and improved cushioning. The pendulum rod 115 is located just below the tension pendulum shaft 113, which can conveniently realize the follow-up of the wool warp and the cloth movement, and achieve a satisfactory effect. The multi-link structure rigidly connected with the main motion of the cloth is used to realize the active and synchronous follow-up of the hair warp. When the tufting loom moves backward, the wool warp will also follow it actively, so as to ensure a higher tension at the end of the raising and achieve higher quality of loops. When the tufting loom moves forward, the wool warp also moves forward actively, and the wool warp tension remains unchanged to avoid fluffing caused by the rise of the wool warp tension.

The composite structure of the cloth moving active follower device and the wool warp tension active control device realizes the perfect combination of high-speed follow and tension active control. It can be seen from the figure that the direction of the force applied by the cloth active follower device to the tension swing shaft 113 is pointing to In the center of the tension rocker arm 203 on the left side, the torque generated on the tension rocker arm 203 is very small, and the influence of the cloth active follower device on the active control of the warp tension can be ignored. That is to say, when the loom is running at high speed and actively following the movement, the tension control of the warp is relatively stable and unaffected. On the other hand, when the tension control device controls the tension change, when the tension rocker arm 203 swings back and forth, the second link 110 in the up-down direction will not be greatly affected by the back and forth swing of the swing shaft driving arm 112 .

The new cloth moving wool warp loom tension control method formed by the cloth moving active follower device + the wool warp tension active control device + the wool warp tension buffer device is the most ideal tension control structure at present, which can be weaved on the towel loom. Provide the best warp tension in the process, and weave perfect loops and forging files at high speed and high efficiency.
