[0036] See also Figure 1 to Figure 3 , a control rope 207 is fixedly installed at the output end of the hydraulic telescopic rod 203, and a guide frame 208 is provided at the upper end of the turning frame 201 near the control rope 207. The guide frame 208 prevents the control rope 207 from contacting and rubbing with the turning frame 201 and causing damage. A fixing block 209 is fixedly installed at one end of the control rope 207 away from the hydraulic telescopic rod 203, and the fixing block 209 is fixedly installed at one end of the limiting frame 202.

A mounting sleeve 211 is rotatably sleeved on the outer wall of the mounting rod 210, and a telescopic spring 212 is fixedly installed between the mounting sleeve 211 and the mounting bracket 1. The telescopic spring 212 installed between the limiting frame 202 and the mounting bracket 1 makes it more convenient for the limiting frame 202 to restore its original state when the control rope 207 no longer pulls the limiting frame 202 to rotate.

[0037] See also Figure 1 to Figure 5The limiting mechanism 3 includes a limiting cylinder 301, and the limiting cylinder 301 is symmetrically installed on the inner wall of the limiting frame 202, a control cylinder 302 is fixedly installed on the inner wall of the limiting frame 202 close to the limiting cylinder 301, a control piston 303 is slidably installed in the inner wall of the control cylinder 302, a control rod 304 is fixedly installed at one end of the control piston 303, and a control tube 305 is fixedly installed at the input end of the control cylinder 302.

[0038] See also Figure 1 to Figure 6 , a control frame 306 is fixedly installed on the end of the control rod 304 away from the control cylinder 302, and control circles 307 are symmetrically installed on both ends of the control frame 306. A control spring 308 is fixedly installed on the inner wall of the limit frame 202 close to the limit cylinder 301. When the control spring 308 contracts the Teflon mesh belt, the control spring 308 is pulled, and the control spring 308 is extended, so that the tension of the Teflon mesh belt is maintained within a suitable range. A mounting ring 309 is fixedly installed on the end of the control spring 308 away from the limit frame 202, and a fixing ring 310 is rotatably installed on the end of the fixing ring 309 away from the control spring 308, and a plurality of fixing clips 311 are rotatably installed on the outer wall of the fixing ring 310 at the upper end. When the Teflon mesh belt is loosened, the Teflon mesh belt The fixing ring 310 of the lower end is provided with a plurality of fixing grooves 313 on the outer wall of the fixing ring 310 close to the fixing groove 311, and the fixing sleeve 314 is provided on the outer wall of the limiting cylinder 301 of the lower end. The fixing grooves 313 provided on the fixing ring 310 of the lower end enable the fixing clamp 311 to push the Teflon mesh belt to fit on the surface of the fixing sleeve 314, so that the Teflon mesh belt will not move and fall off.

[0039] See also Figure 1 to Figure 7The end of the fixing clamp 311 away from the fixing ring 310 is fixedly installed with a rotating rod 315, and the end of the mounting ring 309 close to the rotating rod 315 is fixedly installed with a special-shaped ring 316, and the end of the rotating rod 315 close to the special-shaped ring 316 is rotatably installed with a rolling wheel 317, and the rolling wheel 317 is in contact with the edge of the special-shaped ring 316. Specifically, when the fixing ring 310 rotates following the limiting cylinder 301, the rolling wheel 317 set at one end of the fixing clamp 311 starts to move along the edge of the special-shaped ring 316. When the fixing clamp 311 moves to the position of the Teflon mesh belt, the winding spring 312 pushes the fixing clamp 311 to clamp the Teflon mesh belt. When the fixing clamp 311 moves a certain distance, the fixing clamp 311 opens and does not contact the Teflon mesh belt, so that the Teflon mesh belt is always kept in contact with the surface of the limiting cylinder 301.

[0040] See also Figure 1 to Figure 7 A liquid storage cylinder 318 is fixedly installed on the inner wall of the liquid storage box 204, and a liquid storage piston rod 319 is slidably installed on the inner wall of the liquid storage cylinder 318. An air bag ring 320 is fixedly installed on the lower end of the liquid storage piston rod 319, and the air bag ring 320 floats on the liquid surface in the liquid storage box 204, and the control tube 305 is fixedly installed at the output end of the liquid storage cylinder 318, so that when the air bag ring 320 starts to move upward, the liquid in the liquid storage cylinder 318 is transferred to the control cylinder 302 through the control tube 305, and the control piston 303 pushes the control rod 304 to move, so that the control frame 306 moves.

[0041] See also Figures 1 to 8The winding mechanism 4 includes a winding frame 401, and the winding frame 401 is slidably installed on the upper end of the mounting bracket 1, a winding motor 402 is fixedly installed on the upper end of the winding frame 401, and a winding drum 403 is fixedly installed on the output end of the winding motor 402. Specifically, when the Teflon mesh belt needs to be rolled up, the winding motor 402 is started to make the winding drum 403 start to rotate to wind the Teflon mesh belt, and a support cylinder 404 is fixedly installed at one end of the mounting bracket 1 close to the winding frame 401, and a support piston rod 405 is slidably arranged in the support cylinder 404, and the end of the support piston rod 405 away from the mounting bracket 1 is fixedly installed on the side end of the winding frame 401. Specifically, when the rotation speed of the winding drum 403 increases, the tension exerted on the Teflon mesh belt Increase, at the same time, the winding frame 401 pushes the supporting piston rod 405 to move, so that the winding speed of the Teflon mesh belt can be adjusted, and a reset spring 406 is fixedly installed between the winding frame 401 and the mounting bracket 1, and the reset spring 406 is sleeved on the outer wall of the support tube 404. When the winding speed increases, the reset spring 406 can play a buffering role to avoid the increase in the tension of the Teflon mesh belt due to the increase in the winding speed. A water pipe 407 is fixedly installed at the output end of the support tube 404, and the water pipe 407 is fixedly installed at the side end of the liquid storage tank 204. When the liquid in the support tube 404 enters the liquid storage tank 204 through the water pipe 407, the liquid in the liquid storage tank 204 increases, so that the water level height of the liquid storage tank 204 increases.

[0042] The working principle of the present invention is: after the Teflon mesh belt is placed in the turning mechanism 2, when the Teflon mesh belt needs to be turned over, the hydraulic pump 205 is started to make the hydraulic telescopic rod 203 start to work and contract, so that the control rope 207 pulls the limit frame 202 to start rotating, drives the turning frame 201 to rotate, turns the Teflon mesh belt, and starts the winding motor 402, so that the turning and winding of the Teflon mesh belt is more convenient;

[0043] When the Teflon mesh belt is turned over, the liquid in the hydraulic telescopic rod 203 is transferred to the liquid storage box 204 through the hydraulic pipe 206, so that the liquid level in the liquid storage box 204 rises, and the air bag ring 320 starts to rise, so that the liquid storage piston rod 319 transfers the liquid in the liquid storage cylinder 318 to the control cylinder 302 through the control pipe 305, and the control rod 304 pushes the control frame 306 to move, thereby preventing the fixed clamp 311 from pulling the Teflon mesh belt too much after the Teflon mesh belt is turned over, causing the Teflon mesh belt to be damaged;

[0044] At the same time, the winding speed of the winding motor 402 also affects the tension of the Teflon mesh belt. When the Teflon mesh belt is wound, the winding frame 401 moves to push the supporting piston rod 405 to move, and the liquid in the supporting cylinder 404 is transferred to the liquid storage tank 204 through the water pipe 407, so that the liquid level in the liquid storage tank 204 rises again, avoiding changes in the winding speed, which may cause the Teflon mesh belt to be damaged due to insufficient tension.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed in the present invention, which should be covered by the protection scope of the present invention.
