[0030] The inflatable rubber belt 5 has a second air inlet 22 and an air outlet 23, which are respectively arranged at two ends of the inflatable rubber belt 5, and are respectively connected to an air inlet pipe and an air outlet 23.

[0031] In order to make the yarn clamping force uniform, a first wooden pad 24 is fixed on the yarn angle iron 2, a first felt strip 25 is fixed on the first wooden pad 24, a second wooden pad 26 is fixed on the end of the yarn clamping plate 4 facing away from the inflatable rubber belt 5, and a second felt strip 27 cooperating with the first felt strip 25 is fixed on the second wooden pad 26. The warp yarn can be evenly clamped by the second felt strips 27 and the second felt strips 27.

[0032] like Figure 3 As shown, it also includes a T-plate 28, which is fixed on the frame 1, and the yarn angle iron 2 is fixedly installed on the frame 1 through the T-plate 28.

[0033] A first hinge seat 29 is mounted on the fixing plate 8 , and the cylinder 10 is mounted on the first hinge seat 29 .

[0034] A second hinge seat 30 and a third hinge seat 31 are respectively mounted on the first connecting plate 3 and the second connecting plate 9 , and a flip shaft 32 is mounted between the second hinge seat 30 and the third hinge seat 31 .

[0035] The cylinder 10 is an automatic reset cylinder 10 with a spring. A spring is arranged inside the cylinder 10 . The cylinder 10 is provided with an air inlet connected to an air inlet pipe. When the air inlet is ventilated, the spring is compressed and the piston 13 of the cylinder 10 is retracted into the cylinder 10 .

[0036] The air intake pipes connected to the first air intake port 17, the second air intake port 22 and the cylinder 10 are respectively provided with solenoid valves, and the exhaust pipe connected to the exhaust port 23 is also provided with a solenoid valve. A control box is also installed on the frame, and the control box is electrically connected to these solenoid valves to control the yarn clamping process.

[0037] The working principle of this embodiment is as follows: before clamping the yarn, the cylinder 10 is ventilated. After the air inlet of the cylinder 10 is ventilated, the piston 13 of the cylinder 10 is retracted into the cylinder body, and the cylinder 10 drives the second connecting plate 9, the supporting angle iron 7, the U-shaped channel steel 6 and the yarn clamping plate 4 to turn clockwise, thereby making way for the position of installing the warp yarn, so as to facilitate the placement of the warp yarn in the concave part of the first connecting plate 3, as shown in FIG. Figure 4 As shown;

[0038] Then the cylinder 10 is de-energized and automatically resets under the elastic restoring force of its internal spring, and the piston 13 of the cylinder 10 extends, driving the second connecting plate 9, the supporting angle iron 7, the U-shaped channel steel 6 and the yarn clamping plate 4 to turn counterclockwise until the supporting angle iron 7 is pressed on the first connecting plate 3 and fits with the first connecting plate 3. Figure 6 As shown;

[0039] Then, the first air inlet 17 is ventilated, the piston 13 moves to the side away from the first air inlet 17, the first spring 14 is compressed, the cone head of the locking column 12 extends out of the inner cavity 15 and is inserted into the slot 16, so that the locking block 11 is engaged with the first connecting plate 3, the supporting angle iron 7 and the U-shaped channel steel 6 are kept fixed, and the reverse thrust generated when the yarn is clamped prevents the supporting angle iron 7 and the U-shaped channel steel 6 from deflecting. Fig. 9 As shown;

[0040] Then, air is ventilated to the second air inlet 22 and the air outlet is closed to inflate the inflatable rubber belt 5. After being inflated, the inflatable rubber belt 5 expands and bulges, pushing the yarn clamping plate 4 to approach the yarn angle iron 2. The yarn clamping plate 4 pushes the conical head 20 to move, and the movable sleeve 19 moves with the conical head 20. The second spring 21 is compressed, and the movable sleeve 19 slides smoothly on the fixed sleeve 18. Two guide mechanisms are provided, and the two guide devices are respectively located at the two ends of the yarn angle iron 2. Under the guiding action of the guide mechanism, the two ends of the yarn clamping plate 4 keep synchronously approaching the yarn angle iron 2, so that the end faces of the first felt strip 25 and the second felt strip 27 are parallel and evenly contact the warp yarn, clamping the warp yarn, and the yarn clamping force is uniform and the tension is appropriate, completing the yarn clamping process. Figure 5 As shown;

[0041] When the warp yarn needs to be replaced, the second air inlet 22 is cut off, the air outlet 23 is opened, the inflatable rubber belt 5 becomes deflated, and under the elastic restoring force of the second spring 21, the second spring 21 pushes the conical head 20 and the yarn clamping plate 4 to move, so that the yarn clamping plate 4 moves away from the yarn clamping plate; then the first air inlet 17 is cut off, and under the elastic restoring force of the first spring 14, the locking column 12 retracts into the inner cavity 15 and no longer clamps the first connecting plate 3; then the second air inlet 22 is cut off, and air is ventilated to the cylinder 10, and the cylinder 10 drives the second connecting plate 9, the supporting angle iron 7, the U-shaped channel steel 6 and the yarn clamping plate 4 to flip clockwise, thereby making way for the position for installing the warp yarn and placing the new warp yarn in the recess of the first connecting plate 3.

[0042] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present invention and fall within the protection scope of the present invention.
