At this time, the electric telescopic rod drives the sliding frame to slide downward along the outer wall of the mounting plate. During the downward movement of the rotating column, the side wall of the broken gear will contact the side wall of the rotating rod, presenting a Figure 4 At this time, the broken gear drives the driving column and the rotating column to rotate, and the rotating rotating column drives the folded metal curtain to slide along the inner wall of the sliding groove. In this process, the clamping groove drives the line segment of the yarn wheel to move synchronously, so that the folded metal curtain is wrapped around the outer wall of the rotating column, showing Figure 7 state, at this time the line end of the yarn wheel is clamped by the rotating column and the folded metal curtain, and the top of the outer wall of the yarn wheel is restricted by the extrusion column. At this time, the electric telescopic rod continues to shrink. At this time, the yarn wheel will be pulled and the elastic force detection process is carried out. During the detection process, the compressed position at the bottom of the yarn wheel line end is on the outer wall of the rotating column. Through the application of the above components, it is ensured that when the equipment pulls the yarn wheel, the clamped position and the compressed position of the bottom of the yarn wheel are separated, reducing the influence of the external clamping force on the pulling end and improving the detection accuracy of the equipment.

[0011] Preferably, the driving assembly includes a driving rod 1 fixedly connected to the top of the sliding frame, a plurality of right-angle grooves 2 are opened on the side wall of the driving rod 1, a rotating rod 2 is rotatably connected to the inner wall of the plurality of right-angle grooves 2, a mounting frame is fixedly connected to the side wall of the mounting plate, an L-shaped rod is slidably connected to the inner wall of the mounting frame, a spring 2 is fixedly connected to the bottom of the L-shaped rod, and a cleaning assembly is fixedly connected to the bottom of the sliding frame.

In order to solve the problem that the above-mentioned rotating rod 2 forces the gear to rotate, a right-angle groove 2 is provided inside the device. When the driving rod 1 moves upward, the outer wall of the rotating rod 2 contacts the inner wall of the gear, and at this time, the bottom plane of the rotating rod 2 contacts the plane of the inner wall of the gear. Therefore, when the driving rod 1 moves upward, the gear can rotate, and when the driving rod 1 moves downward, the rotating rod 2 contacts the gear and will tilt upward with the connection point as the center, presenting a Figure 9 In the middle G state, the driving rod will no longer drive the gear to rotate when it moves down. Similarly, when the broken gear reaches the bottom and resets, when the electric telescopic rod drives the broken gear to move up, the side wall of the broken gear will contact the bottom inclined surface of the rotating rod 1, forcing the rotating rod 1 to tilt upward with the connection point as the center. Therefore, when the broken gear moves up, the broken gear will no longer rotate. The application of the above components can avoid the misalignment of components during the operation of the equipment, which affects the detection accuracy.

[0014] Preferably, the cleaning assembly further comprises a storage tank fixedly connected to the air pressure tank away from the mounting disc, a L-shaped plate is slidably connected to the inner wall of the storage tank, an exhaust port one is formed in the side wall of the L-shaped plate, an exhaust port two is formed in the side of the storage tank close to the mounting disc, a spring telescopic rod is fixedly connected to the top of the L-shaped plate, the end of the spring telescopic rod away from the L-shaped plate is fixedly connected to the inner wall of the air pressure tank, and four air injection pipes are throughly connected to the side of the storage tank away from the mounting disc, by using the force of the sliding frame moving downward, the cleaning assembly is arranged in the equipment, with the descending of the electric telescopic rod, the bottom of the contact rod will be in contact with the top of the base, at this time, the contact rod will drive the piston plate to move upward along the inner wall of the air pressure tank and compress the gas in the air pressure tank, so that the gas in the air pressure tank forms a high pressure state, with the contraction of the electric telescopic rod, the top of the piston plate will be in contact with the bottom of the L-shaped plate, forcing the L-shaped plate to move upward along the inner wall of the storage tank, at this time, the exhaust port one and the exhaust port two will coincide to form an exhaust gap, and the high-pressure gas in the air pressure tank will enter the storage tank through the gap, and finally be sprayed on the bottom of the unfolded metal curtain through the air injection pipe, by the application of the above-mentioned assembly, the broken end of the yarn wheel still stays in the clamping groove when the unfolded metal curtain is unfolded, which affects the subsequent clamping effect.

[0015] A method for using a yarn elasticity detection device, comprising the following steps:

[0016] S1: placing the yarn, installing the yarn wheel on the side wall of the mounting disc, and letting the wire end of the yarn wheel fall downward;

[0017] S2: guiding the wire, ensuring that the wire end of the yarn wheel passes through the gap between the extrusion columns and the clamping groove, and then connecting the power supply of the electric telescopic rod.

[0018] The present application has the following beneficial effects:

[0019] (1) The present application is aimed at the problem that the clamping position of the yarn wheel will be broken early due to the clamping force, and the clamping mechanism and the detection assembly are arranged in the equipment, before use, the yarn wheel is installed on the side wall of the mounting disc, the wire end of the yarn wheel is let to fall downward, and the wire end of the yarn wheel is ensured to pass through the gap between the extrusion columns and the clamping groove, and then the power supply of the electric telescopic rod is connected, at this time, the electric telescopic rod drives the sliding frame to slide downward along the outer wall of the mounting disc, in the process of the rotating column moving downward, the side wall of the broken gear will be in contact with the side wall of the rotating rod one, and the state of Figure 1 is presented, at this time, the broken gear drives the driving column and the rotating column to rotate, the rotating rotating column drives the unfolded metal curtain to slide along the inner wall of the sliding groove, in this process, the clamping groove drives the wire segment of the yarn wheel to displace synchronously, so that the unfolded metal curtain is wrapped around the outer wall of the rotating column, and the state of Figure 4 is presented. Figure 7state, at this time the line end of the yarn wheel is clamped by the rotating column and the folded metal curtain, and the top of the outer wall of the yarn wheel is restricted by the extrusion column. At this time, the electric telescopic rod continues to shrink. At this time, the yarn wheel will be pulled and the elastic force detection process is carried out. During the detection process, the compressed position at the bottom of the yarn wheel line end is on the outer wall of the rotating column. Through the application of the above components, it is ensured that when the equipment pulls the yarn wheel, the clamped position and the compressed position of the bottom of the yarn wheel are separated, reducing the influence of the external clamping force on the pulling end and improving the detection accuracy of the equipment.

[0020] (2) The present invention utilizes the characteristics of the rotating column and the folded metal curtain clamping the yarn wheel end. When the incomplete gear rotates, since the incomplete gear itself has only half the volume, it will force the incomplete gear to only drive the rotating column to rotate half a circle, and finally present the following Figure 7 When the gear is in the state of the broken gear in the middle, and the spring 1 will accumulate mechanical power at this time, and when it continues to move downward, the edge of the broken gear will slide downward along the outer wall of the rotating rod 1. Through the application of the above components, the broken gear is prevented from driving the driving column to rotate too long, affecting the detection accuracy of the yarn wheel; in addition, a driving component is provided inside the device. As the electric telescopic rod continues to pull downward, the yarn wheel will break, one end is at the bottom of the rotating column, and the other end is at the bottom of the extrusion column. When the sliding frame reaches the position of the groove, the broken gear loses contact with the outer wall of the rotating rod 1. At this time, the spring 1 and the spring 4 will release the mechanical power, forcing the rotating column and the folding metal curtain to reset, and the reset folding metal curtain will separate from the outer wall of the rotating column and will no longer clamp the broken wire end of the yarn wheel; then the electric telescopic rod is extended, forcing the sliding frame to move upward along the outer wall of the mounting plate. At this time, the upward sliding frame drives the driving rod 1 to move upward synchronously, and the driving rod 1 forces the gear on the right to rotate counterclockwise through the rotating rod 2, showing as follows Figure 8 state, and at this time the two meshing and rotating extrusion columns will force the line end of the yarn wheel to be transmitted downward, and the line end of the yarn wheel will pass through the clamping groove again. When the electric telescopic rod is retracted, the detection process will be carried out again. Through the application of the above components, the equipment can realize autonomous wiring, and can perform multiple tests on the first sample, thereby increasing the detection data of the equipment.

[0021] (3) In order to solve the problem that the rotating rod 2 forces the gear to rotate, the present invention provides a right-angle groove 2 inside the device. When the driving rod 1 moves upward, the outer wall of the rotating rod 2 contacts the inner wall of the gear, and at this time, the bottom plane of the rotating rod 2 contacts the inner wall plane of the gear. Therefore, when the driving rod 1 moves upward, the gear can rotate. When the driving rod 1 moves downward, the rotating rod 2 contacts the gear and will tilt upward with the connection point as the center, presenting a Figure 9In the state of the middle G, the driving rod is moved down and no longer drives the gear to rotate; similarly, after the defective gear reaches the bottom and is reset, when the electric telescopic rod drives the defective gear to move up, the side wall of the defective gear will contact the bottom inclined surface of the rotating rod, forcing the rotating rod to tilt upward around the connecting point. Therefore, when the defective gear moves up, the defective gear will no longer rotate. Through the application of the above components, the misalignment of the components during the operation of the device is avoided, and the detection accuracy is affected. In addition, during the operation of the device, spring two drives the L-shaped rod to limit the two gears, avoiding the small-angle rotation of the gears when the yarn wheel is subjected to tension, thereby affecting the detection accuracy of the device.

[0022] (4) The application utilizes the force of the sliding frame moving down to set a cleaning assembly inside the device. As the electric telescopic rod descends, the bottom of the contact rod will contact the top of the base. At this time, the contact rod will drive the piston plate to move upward along the inner wall of the air pressure tank and compress the gas inside the air pressure tank, so that the gas inside the air pressure tank forms a high-pressure state. As the electric telescopic rod retracts, the top of the piston plate will contact the bottom of the L-shaped plate, forcing the L-shaped plate to move upward along the inner wall of the storage tank. At this time, the exhaust port one and the exhaust port two will coincide to form an exhaust gap. The high-pressure gas inside the air pressure tank will enter the storage tank through the above gap and finally be sprayed at the bottom of the unfolded metal curtain through the air jet pipe. Through the application of the above components, the broken thread end of the yarn wheel is prevented from remaining in the clamping groove when the unfolded metal curtain is unfolded, thereby affecting the subsequent clamping effect.

[0045] The detection component 3 also includes a folding metal curtain 35 rotatably connected to the side wall of the rotating column 34.

[0047] The detection component 3 also includes a plurality of right-angled slots 311 provided on the side wall of the limiting rod 39, and a rotating rod 312 is rotatably connected to the inner wall of the plurality of right-angled slots 311. The end of the driving column 37 away from the rotating column 34 is fixedly connected to a spring 313. The top of the sliding frame 31 is fixedly connected to a fixed square plate 314. The end of the spring 313 away from the driving column 37 is fixedly connected to the side wall of the fixed square plate 314. Before use, the yarn wheel 21 is installed on the side wall of the mounting plate 1, and the end of the yarn wheel 21 is hung down, and it is ensured that the end of the yarn wheel 21 passes through the gap between the extrusion columns 23 and the clamping groove 36, presenting as shown in the figure. Figure 1 The electric telescopic rod 12 is then powered on. The electric telescopic rod 12 drives the sliding frame 31 to slide downward along the outer wall of the mounting plate 1. As the rotating column 34 moves downward, the side wall of the defective gear 38 contacts the side wall of the rotating rod 1 312, presenting a Figure 4 At this time, the broken gear 38 drives the driving column 37 and the rotating column 34 to rotate, and the rotating rotating column 34 drives the folded metal curtain 35 to slide along the inner wall of the sliding groove 33. In this process, the clamping groove 36 drives the line segment of the yarn wheel 21 to move synchronously, so that the folded metal curtain 35 is wrapped around the outer wall of the rotating column 34, presenting Figure 7 state, at this time, the wire end of the yarn wheel 21 is clamped by the rotating column 34 and the folded metal curtain 35, and the top of the outer wall of the yarn wheel 21 is clamped and restricted by the extrusion column 23. At this time, the electric telescopic rod 12 continues to shrink. At this time, the yarn wheel 21 will be pulled and the elastic force detection process is carried out. During the detection process, the compressed position at the bottom of the wire end of the yarn wheel 21 is on the outer wall of the rotating column 34. Through the application of the above components, it is ensured that when the equipment pulls the yarn wheel 21, the clamped position and the compressed position at the bottom of the yarn wheel 21 are separated, thereby reducing the influence of the external clamping force on the pulling end and improving the detection accuracy of the equipment.

[0048] For example 2, please refer to Figure 8 - Figure 14 The present invention is a yarn elasticity detection device. On the basis of embodiment 1, the driving component 4 includes a driving rod 1 41 fixedly connected to the top of the sliding frame 31, and a plurality of right-angle grooves 2 42 are opened on the side wall of the driving rod 1 41. The inner walls of the plurality of right-angle grooves 2 42 are rotatably connected with a rotating rod 2 43. The side wall of the mounting plate 1 is fixedly connected with a mounting frame 44, and the inner wall of the mounting frame 44 is slidably connected with an L-shaped rod 45. The bottom of the L-shaped rod 45 is fixedly connected with a spring 2 46. The bottom of the sliding frame 31 is fixedly connected with a cleaning component 5. By utilizing the characteristics of the above-mentioned rotating column 34 and the folded metal curtain 35 clamping the line end of the yarn wheel 21, when the incomplete gear 38 rotates, since the incomplete gear 38 itself has only half the volume, this will force the incomplete gear 38 to only drive the rotating column 34 to rotate half a circle, and finally present as shown below. Figure 7The broken gear 38 is in the state of the broken gear 38, and the spring 1 313 will accumulate mechanical power at this time. When it continues to move downward, the edge of the broken gear 38 will slide downward along the outer wall of the rotating rod 1 312. Through the application of the above components, the broken gear 38 is prevented from driving the driving column 37 to rotate too long a distance, which affects the detection accuracy of the yarn wheel 21.

[0049] The cleaning component 5 includes an air pressure box 51 fixedly connected to the bottom of the sliding frame 31, a piston plate 52 is slidably connected to the inner wall of the air pressure box 51, a contact rod 53 is fixedly connected to the bottom of the piston plate 52, a pulling line 54 is fixedly connected to the bottom of the contact rod 53, and the pulling line 54 is fixedly connected to the top of the base 11 at one end away from the contact rod 53. A driving component 4 is provided inside the device. As the electric telescopic rod 12 continues to pull downward, the yarn wheel 21 will break, one end is at the bottom of the rotating column 34, and the other end is at the bottom of the extrusion column 23. When the sliding frame 31 reaches the position of the groove 310, the yarn wheel 21 will break. When the gear 38 loses contact with the outer wall of the rotating rod 1 312, the spring 1 313 and the spring 4 315 will release the mechanical power, forcing the rotating column 34 and the folding metal curtain 35 to return to their original position. The restored folding metal curtain 35 will separate from the outer wall of the rotating column 34 and will no longer clamp the broken end of the yarn wheel 21. Subsequently, the electric telescopic rod 12 will extend, forcing the sliding frame 31 to move upward along the outer wall of the mounting plate 1. At this time, the upward sliding frame 31 drives the driving rod 1 41 to move upward synchronously, and the driving rod 1 41 forces the gear 22 on the right to rotate counterclockwise through the rotating rod 2 43, resulting in the following Figure 8 state, and at this time the two meshing and rotating squeezing columns 23 will force the thread end of the yarn wheel 21 to be transmitted downward, and the thread end of the yarn wheel 21 will pass through the clamping groove 36 again. When the electric telescopic rod 12 is retracted, the detection process will be carried out again. Through the application of the above components, the equipment can realize autonomous wiring, and can perform multiple tests on the first sample, thereby increasing the detection data of the equipment.

[0050] The cleaning component 5 also includes an exhaust port 55 opened on the top of the piston plate 52, and a fixed bracket 56 is fixedly connected to the inner wall of the exhaust port 55, and a spring sliding rod 57 is slidably connected to the inner wall of the fixed bracket 56. A blocking ball 58 is fixedly connected to the bottom of the spring sliding rod 57. In order to solve the problem that the rotating rod 23 forces the gear 22 to rotate, a right-angle groove 242 is provided inside the device. When the driving rod 1 41 moves upward, the outer wall of the rotating rod 23 contacts the inner wall of the gear 22, and at this time, the bottom plane of the rotating rod 23 contacts the inner wall plane of the gear 22. Therefore, when the driving rod 1 41 moves upward, the gear 22 can rotate, and when the driving rod 1 41 moves downward, the rotating rod 23 contacts the gear 22 and will tilt upward with the connection point as the center, presenting a shape as shown in the figure. Figure 9In the middle G state, the driving rod 41 moves downward and will no longer drive the gear 22 to rotate; similarly, when the broken gear 38 reaches the bottom and resets, when the electric telescopic rod 12 drives the broken gear 38 to move upward, the side wall of the broken gear 38 will contact the bottom inclined surface of the rotating rod 312, forcing the rotating rod 312 to tilt upward with the connection point as the center. Therefore, when the broken gear 38 moves upward, the broken gear 38 will no longer rotate. Through the application of the above components, the misalignment of the components during operation of the equipment is avoided, which affects the detection accuracy.

[0051] The cleaning component 5 also includes a storage box 59 fixedly connected to the end of the air pressure box 51 away from the mounting plate 1, an L-shaped plate 510 is slidably connected to the inner wall of the storage box 59, an exhaust port 1 511 is provided on the side wall of the L-shaped plate 510, and an exhaust port 2 512 is provided on the side of the storage box 59 close to the mounting plate 1, a spring telescopic rod 513 is fixedly connected to the top of the L-shaped plate 510, and the spring telescopic rod 513 is fixedly connected to the inner wall of the air pressure box 51 at one end away from the L-shaped plate 510, and four air injection pipes 514 are connected to the side of the storage box 59 away from the mounting plate 1. By utilizing the downward force of the above-mentioned sliding frame 31, a cleaning component 5 is provided inside the device. As the electric telescopic rod 12 descends, the bottom of the contact rod 53 will contact the top of the base 11, and at this time the contact rod 53 will drive The piston plate 52 moves upward along the inner wall of the air pressure box 51 and compresses the gas inside the air pressure box 51, so that the gas inside the air pressure box 51 forms a high-pressure state. As the electric telescopic rod 12 contracts, the top of the piston plate 52 will contact the bottom of the L-shaped plate 510, forcing the L-shaped plate 510 to move upward along the inner wall of the storage box 59. At this time, the exhaust port 1 511 and the exhaust port 2 512 will overlap to form an exhaust gap, and the high-pressure gas inside the air pressure box 51 will enter the storage box 59 through the above gap, and finally be sprayed on the bottom of the opened folding metal curtain 35 through the air jet pipe 514. Through the application of the above components, it is avoided that the broken thread end of the yarn wheel 21 remains in the clamping groove 36 when the folding metal curtain 35 is extended, affecting the subsequent clamping effect.

[0052] The method for using the yarn elasticity testing device includes the following steps:

[0053] S1: Place the yarn: Install the yarn wheel 21 on the side wall of the mounting plate 1, and let the yarn end of the yarn wheel 21 hang down;

[0054] S2: Guiding line: Ensure that the thread end of the yarn wheel 21 passes through the gap between the squeezing columns 23 and the clamping groove 36, and then turn on the power of the electric telescopic rod 12.

[0055] A specific application of this embodiment is: before use, the yarn wheel 21 is installed on the side wall of the mounting plate 1, the thread end of the yarn wheel 21 is hung down, and it is ensured that the thread end of the yarn wheel 21 passes through the gap between the extrusion columns 23 and the clamping groove 36, presenting the following Figure 1 The electric telescopic rod 12 is then powered on. The electric telescopic rod 12 drives the sliding frame 31 to slide downward along the outer wall of the mounting plate 1. As the rotating column 34 moves downward, the side wall of the defective gear 38 contacts the side wall of the rotating rod 1 312, presenting a Figure 4 At this time, the broken gear 38 drives the driving column 37 and the rotating column 34 to rotate, and the rotating rotating column 34 drives the folded metal curtain 35 to slide along the inner wall of the sliding groove 33. In this process, the clamping groove 36 drives the line segment of the yarn wheel 21 to move synchronously, so that the folded metal curtain 35 is wrapped around the outer wall of the rotating column 34, presenting Figure 7 state, at this time, the wire end of the yarn wheel 21 is clamped by the rotating column 34 and the folded metal curtain 35, and the top of the outer wall of the yarn wheel 21 is clamped and restricted by the extrusion column 23. At this time, the electric telescopic rod 12 continues to shrink. At this time, the yarn wheel 21 will be pulled and the elastic force detection process is carried out. During the detection process, the compressed position at the bottom of the wire end of the yarn wheel 21 is on the outer wall of the rotating column 34. Through the application of the above components, it is ensured that when the equipment pulls the yarn wheel 21, the clamped position and the compressed position at the bottom of the yarn wheel 21 are separated, thereby reducing the influence of the external clamping force on the pulling end and improving the detection accuracy of the equipment.

[0056] By utilizing the characteristics of the rotating column 34 and the folded metal curtain 35 clamping the yarn wheel 21, when the incomplete gear 38 rotates, since the incomplete gear 38 itself has only half the volume, this will force the incomplete gear 38 to only drive the rotating column 34 to rotate half a circle, and finally present as shown below. Figure 7The broken gear 38 is in the state of the broken gear 38, and the spring 1 313 will accumulate mechanical power at this time. When it continues to move downward, the edge of the broken gear 38 will slide downward along the outer wall of the rotating rod 1 312. Through the application of the above components, the broken gear 38 is prevented from driving the driving column 37 to rotate too long, which affects the detection accuracy of the yarn wheel 21. In addition, a driving component 4 is provided inside the device. As the electric telescopic rod 12 continues to pull downward, the yarn wheel 21 will break, with one end at the bottom of the rotating column 34 and the other end at the bottom of the extrusion column 23. When the sliding frame 31 reaches the position of the groove 310, The broken gear 38 loses contact with the outer wall of the rotating rod 1 312. At this time, the spring 1 313 and the spring 4 315 will release the mechanical power, forcing the rotating column 34 and the folding metal curtain 35 to reset. The reset folding metal curtain 35 will separate from the outer wall of the rotating column 34 and will no longer clamp the broken wire end of the yarn wheel 21. Subsequently, the electric telescopic rod 12 will extend, forcing the sliding frame 31 to move upward along the outer wall of the mounting plate 1. At this time, the upward sliding frame 31 drives the driving rod 1 41 to move upward synchronously, and the driving rod 1 41 forces the right gear 22 to rotate counterclockwise through the rotating rod 2 43, presenting the following Figure 8 state, and at this time the two meshing and rotating squeezing columns 23 will force the thread end of the yarn wheel 21 to be transmitted downward, and the thread end of the yarn wheel 21 will pass through the clamping groove 36 again. When the electric telescopic rod 12 is retracted, the detection process will be carried out again. Through the application of the above components, the equipment can realize autonomous wiring, and can perform multiple tests on the first sample, thereby increasing the detection data of the equipment.

[0057] In order to solve the problem that the rotating rod 23 forces the gear 22 to rotate, a right-angle groove 242 is provided inside the device. When the driving rod 1 41 moves upward, the outer wall of the rotating rod 23 contacts the inner wall of the gear 22, and at this time, the bottom plane of the rotating rod 23 contacts the inner wall plane of the gear 22. Therefore, when the driving rod 1 41 moves upward, the gear 22 can rotate. When the driving rod 1 41 moves downward, the rotating rod 23 contacts the gear 22 and will tilt upward with the connection point as the center, presenting a Figure 9 When the gear 38 is in the middle G state, the driving rod 41 moves downward and no longer drives the gear 22 to rotate; similarly, when the incomplete gear 38 reaches the bottom and resets, the electric telescopic rod 12 drives the incomplete gear 38 to move upward, the side wall of the incomplete gear 38 will contact the bottom inclined surface of the rotating rod 312, forcing the rotating rod 312 to tilt upward with the connection point as the center. Therefore, when the incomplete gear 38 moves upward, the incomplete gear 38 will no longer rotate. The application of the above components can avoid the misalignment of the components during the operation of the equipment, thereby affecting the detection accuracy. In addition, when the equipment is running, the spring 2 46 drives the L-shaped rod 45 to limit the two gears 22, thereby preventing the gear 22 from rotating at a small angle when the yarn wheel 21 is subjected to tension, thereby affecting the detection accuracy of the equipment.

[0058] By utilizing the downward force of the sliding frame 31, a cleaning assembly 5 is provided inside the device. As the electric telescopic rod 12 descends, the bottom of the contact rod 53 will contact the top of the base 11. At this time, the contact rod 53 will drive the piston plate 52 to move upward along the inner wall of the air pressure box 51 and compress the gas inside the air pressure box 51, so that the gas inside the air pressure box 51 forms a high-pressure state. As the electric telescopic rod 12 contracts, the top of the piston plate 52 will contact the bottom of the L-shaped plate 510, forcing the L The mold plate 510 moves upward along the inner wall of the storage box 59. At this time, the exhaust port 1 511 and the exhaust port 2 512 will overlap to form an exhaust gap, and the high-pressure gas inside the air pressure box 51 will enter the storage box 59 through the above gap, and finally be sprayed on the bottom of the opened folding metal curtain 35 through the air jet pipe 514. Through the application of the above components, it is avoided that the broken thread end of the yarn wheel 21 remains in the clamping groove 36 when the folding metal curtain 35 is extended, thereby affecting the subsequent clamping effect.

[0059] In the process of the sliding frame 31 moving upward, as the distance between the base 11 and the sliding groove 33 increases, the pulling line 54 will force the contact rod 53 and the piston plate 52 to slide downward. At this time, under the push of the spring telescopic rod 513, the exhaust port 1 511 and the exhaust port 2 512 are misaligned again, so that a closed space is formed inside the air pressure box 51 again. When the piston plate 52 continues to move downward, a negative pressure environment will be formed inside the air pressure box 51. The negative pressure will force the blocking ball 58 to move upward, so that the external gas enters the air pressure box 51 through the gap between the blocking ball 58 and the exhaust port 55.
