Neither the passive swing warp tension control method nor the purely rigid active swing can adapt to the situation where there are fewer warp yarns. The low warp tension may cause the machine to operate at a lower rate, or the inertia of the raising rod may cause the hair extraction to fail to operate at high speed. High-speed cloth-moving towel looms are in urgent need of a new warp tension control structure to solve the problem of high-quality and high-speed weaving of towels. Therefore, the existing technology is in urgent need of further improvement. Summary of the invention

[0041] The present invention is described in detail below in conjunction with the accompanying drawings:

[0042] Combination Figures 1 to 5 An actively controlled warp tension system comprises a wall panel 4, an active following device 1 for cloth movement, an active warp tension control device 2 and a warp tension buffer device 3. There are two wall panels 4, and the two wall panels 4 are arranged opposite to each other, one on the left and the other on the right.

[0043] The active control device 2 for the wool warp tension includes a supporting swing shaft 205, a tension rocker arm 203 and a rocker arm driving mechanism. The supporting swing shaft 205 is a hollow shaft with a circular cross-section. The supporting swing shaft 205 is horizontally arranged between the two wall panels 4. Its two ends are respectively rotatably matched with the corresponding side wall panels 4 through a rocker arm support 201. Each rocker arm support 201 is fixedly installed on the upper inner side of the same side wall panel 4. The two ends of the supporting swing shaft 205 are rotatably connected with the corresponding rocker arm support 201 through a bearing.

[0044] There are two tension rocker arms 203, which are symmetrically arranged below the two ends of the supporting swing shaft 205.

[0046] One end of the tension link 206 is hingedly connected to the tension torsion arm 207, and the other end is hingedly connected to the lower end of the left tension rocker arm 203. In the working state, the tension servo motor 209 drives the tension rocker arm 203 to swing back and forth around the support swing shaft 205 through the tension torsion arm 207 and the tension link 206. The lower end of the left tension rocker arm 203 is connected to the tension link 206 through a pin shaft and a bearing, and the other end of the tension link 206 is connected to the outer end of the tension torsion arm 207 through a pin shaft and a bearing. The center of the tension torsion arm 207 is installed on the tension drive shaft 208 and fastened together. The tension drive shaft 208 is connected to the tension servo motor 209 through a transmission mechanism to realize the control of the tension rocker arm 203.

[0047] The active following device 1 for fabric movement includes a tension adjustment mechanism and a connecting rod transmission mechanism. The tension adjustment mechanism is located below the supporting swing shaft 205 and includes a tension swing shaft 113 and a swing rod 115. The tension swing shaft 113 and the swing rod 115 are both thin-walled straight tubes with circular cross-sections and are arranged relatively parallel to the supporting swing shaft 205. The tension swing shaft 113 is transversely arranged on two tension rocker arms 203. The two ends of the tension swing shaft 113 are respectively connected to the middle of the two tension rocker arms 203 for rotation. The middle of the two tension rocker arms 203 is respectively provided with a bearing. The two ends of the tension swing shaft 113 are respectively supported by the bearings in the middle of the two tension rocker arms 203. The tension swing shaft 113 can rotate around the supporting swing shaft 205 with the tension rocker arms 203, and can also rotate around its own axis relative to the tension rocker arms 203. The two tension rocker arms 203 support the active following device for fabric movement to realize a composite motion for controlling the tension of the wool warp.

[0048] The swing rod 115 is arranged below the tension swing shaft 113 and is fixedly connected thereto via a swing rod fixing clamp 114. There are a plurality of swing rod fixing clamps 114, which are sequentially arranged between the tension swing shaft 113 and the swing rod 115 along the axial direction of the tension swing shaft 113. One end of each swing rod fixing clamp 114 is fixedly connected to the tension swing shaft 113, and the other end is fixedly connected to the swing rod 115.

[0049] The swing rod fixing clamp 114 includes a clamping plate and a clamping hoop. One end of the clamping plate is provided with a U-shaped mounting groove, and the other end is provided with a swing rod through hole. The clamping hoop is arranged at the opening of the U-shaped mounting groove, and the tension swing shaft 113 is located in the U-shaped mounting groove. One end of the clamping plate is fixedly connected to the tension swing shaft 113 through the clamping hoop. The swing rod 115 is located inside the swing rod through hole, and the other end of the clamping plate is fixedly connected to the swing rod 115 through a first set screw.

[0050] An arc-shaped pad is provided between the clamp and the tension swing shaft 113, and a first set screw is provided on the clamp, and the first set screw locks the tension swing shaft 113 through the arc-shaped pad. A second set screw is provided at the other end of the clamp corresponding to the through hole of the swing rod, and the second set screw locks the swing rod 115 in the through hole of the swing rod through a U-shaped clamping plate.

[0051] One end of the connecting rod transmission mechanism is arranged on the left wall panel 4 through the raising support 101, and the other end is fixedly connected to the corresponding end of the tension swing shaft 113. The connecting rod transmission mechanism includes a raising swing arm 102, a first connecting rod 105, a transfer rocker arm 107, a second connecting rod 110 and a swing shaft driving arm 112, and one end of the raising swing arm 102 is hinged to the raising support 101. The raising swing arm 102 is driven by a cloth-moving raising motor to generate a cloth-moving motion, which is the basic motion of the cloth-moving towel loom, belongs to the prior art, and is not described in detail here. The transfer rocker arm 107 is arranged on the left wall panel 4, and the raising swing arm 102 is connected to one end of the transfer rocker arm 107 through the first connecting rod 105, and the other end of the transfer rocker arm 107 is connected to one end of the swing shaft driving arm 112 through the second connecting rod 110, and the other end of the swing shaft driving arm 112 is fixedly connected to the tension swing shaft 113.

[0052] Specifically, one end of the fuzzing swing arm 102 is rotatably matched with the fuzzing support 101 through the first support shaft 103, one end of the first support shaft 103 is installed on the fuzzing support 101, and the fuzzing swing arm 102 is installed on the first support shaft 103 through a bearing. The first support shaft 103 supports the fuzzing swing arm 102, and the fuzzing swing arm 102 can rotate and swing around the first support shaft 103. The other end of the fuzzing swing arm 102 can be rotatably connected to the driving part of the cloth-driven fuzzing motor, and the driving part of the cloth-driven fuzzing motor drives the fuzzing swing arm 102 to swing back and forth around the first support shaft 103. The transfer rocker arm 107 is an L-shaped structure, and its corner position is rotatably matched with the left wall panel 4 through the second support shaft 108. One end of the second support shaft 108 is installed on the inner side of the left wall panel 4. The transfer rocker arm 107 is installed on the second support shaft 108 through a bearing. The second support shaft 108 supports the transfer rocker arm 107, and the transfer rocker arm 107 can rotate and swing around the second support shaft 108.

[0053] One end of the first connecting rod 105 is hinged to the middle of the fluffing swing arm 102 through the first pin 104, and the other end is hinged to one end of the transfer rocker arm 107 through the second pin 106. One end of the transfer rocker arm 107 is provided with a long hole, and the second pin 106 is located in the long hole. By adjusting the position of the second pin 106 in the long hole, the distance between the second pin 106 and the rotation center of the transfer rocker arm 107 can be changed, and the swing angle of the transfer rocker arm 107 can be changed to achieve the adjustment of the output swing amount. One end of the second connecting rod 110 is hinged to the other end of the transfer rocker arm 107 through the third pin 109. The other end of the transfer rocker arm 107 is provided with a round hole, and the third pin 109 is located in the round hole. The other end of the second connecting rod 110 is hinged to one end of the swing shaft driving arm 112 through the fourth pin 111.

[0054] In the working state, the raising swing arm 102 drives the transfer rocker arm 107 to rotate around the second support shaft 108 through the first connecting rod 105, and the transfer rocker arm 107 drives the tension swing shaft 113 to rotate around its axis through the second connecting rod 110 and the swing shaft driving arm 112, and then the swing rod 115 realizes the following swing through the swing rod fixing clamp 114. The swing rod fixing clamp 114 is light in weight, and the swing rod 115 is a light thin-walled tube to reduce the mass inertia of the swinging part, so as to facilitate high-speed operation. It can be seen from the figure that the swing direction of the swing rod 115 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 rod also follows forward, and when the raising swing arm swings backward, the swing rod also follows backward.

[0055] The force applied to the supporting swing shaft 205 is transmitted to the tension servo motor 209 through the transmission mechanism and reaches a balance. By actively controlling the torque of the tension servo motor 209, the different tensions of the wool warp yarns applied to the supporting swing shaft 205 can be controlled to meet the requirements of the wool warp tension in different states of weaving loops, forging and parking.

[0056] The warp tension buffer device 3 is transversely arranged between the support swing shaft 205 and the tension swing shaft 113, and its two ends are respectively fixedly connected to the two wall panels 4. The 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 relatively parallel to the support swing shaft 205, and its left and right ends are respectively fixedly connected to the two wall panels 4 through a buffer support 301.

[0057] 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. The buffer sleeve 303 is fixed to the rear side wall of the buffer support shaft 302 at both ends along its circumference through buffer pressure plates 304. There are several buffer pressure 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.

[0058] The buffer sleeve 303 and the buffer support shaft 302 are connected in an inscribed state, and a deformation cavity with a crescent-shaped cross section is formed between the inner wall of the buffer sleeve 303 and the buffer support shaft 302. When pressure is applied to the buffer sleeve 303 away from the buffer support shaft, spring plate-type buffering can be achieved through the deformation of the buffer sleeve 303. When a larger pressure is applied, the buffer sleeve 303 deforms more and can contact the outer circumferential surface of the buffer support shaft, so that the tension of the hair warp is rapidly increased. Figure 2 or Figure 4 It can be seen from the figure that the buffer sleeve 303 is located closer to the front of the loom, which can increase the covering angle of the wool warp and improve the tension buffering effect.

[0059] from Figure 2 It can be seen from the figure that the wool warp yarn direction, the wool warp first passes through the support swing shaft 205, then passes through the buffer sleeve 303 to reach the tension swing shaft 113, and then is sent to the front of the loom by the swing rod 115. The support swing shaft 205 plays a role in guiding and positioning the wool warp, and the buffer sleeve 303 is relatively close to the front of the loom. The wool warp forms a larger wrap angle on the buffer sleeve 303, and also increases the wrap angle of the warp yarn on the tension swing shaft 113, which is helpful for the precise control of tension sensing and the improvement of buffering effect. The swing rod 115 is located directly below the tension swing shaft 113, which can easily realize the follow-up of the wool warp and the cloth movement to achieve satisfactory results. The multi-link structure rigidly connected with the main movement of the cloth movement realizes the active synchronous following of the wool warp. When the weaving opening of the towel loom moves backward, the wool warp also actively follows and moves backward, ensuring that the wool has a higher tension at the end of the raising and achieving a higher quality of the terry loop. When the weaving opening of the towel loom moves forward, the wool warp also moves forward actively, and the tension of the wool warp remains unchanged, avoiding the increase of the wool warp tension and causing wool pulling.

[0060] The composite structure of the active following device for fabric movement and the active control device for wool warp tension realizes the perfect combination of high-speed following and active tension control. As can be seen from the figure, the direction in which the active following device for fabric movement applies force to the tension swing shaft 113 is toward the center of the tension rocker arm 203 on the left side, and the torque generated on the tension rocker arm 203 is very small, and the influence of the active following device for fabric movement on the active control of wool warp tension can be ignored. In other words, the wool warp tension control is relatively stable and unaffected when the loom is actively following the movement at high speed. On the other hand, when the tension control device is controlling the change of tension and the tension rocker arm 203 swings back and forth, the second connecting rod 110 in the up and down direction will not be greatly affected by the swing of the swing shaft driving arm 112.

[0061] The new wool warp tension control method of the wool warp loom formed by the cloth-moving active following device + the wool warp tension active control device + the wool warp tension buffer device is the most ideal tension control structure at present. It can provide the best wool warp tension in the weaving process of the towel loom, and weave perfect terry loops and forgings at high speed and high efficiency.
