It has a very low friction coefficient and is a good anti-friction and self-lubricating material. Due to its non-polarity, heat resistance and non-absorbency, it is also an excellent electrical insulation material. It also has excellent aging resistance, non-stickiness and non-flammability. The pipes made from it are widely used in machinery, chemical industry, aviation, electrical and electronics, national defense industry, cutting-edge technology, medical care and electrical insulation and other fields.

Figure 2 This is a schematic diagram of the structure of the pressing wheel of the PTFE tube double-slide traction processing device provided in one embodiment of the present application. Figure 3 yes Figure 1 Schematic diagram of the structure of the middle guide device. Figure 4 yes Figure 1 Schematic diagram of the structure of the second cylinder and the second clamp. Figure 1-4 As shown, the embodiment of the present application provides a PTFE tube double-slide traction processing device, including an etching tank 13, a cleaning tank is arranged at one end of the etching tank 13, a blowing device 10 is arranged at one end of the cleaning tank away from the etching tank 13, and a cutting device 8 is arranged at one side of the blowing device 10 away from the cleaning tank;

[0029] It should be noted that the etching tank 13 contains etching liquid, and the cleaning tank contains cleaning liquid. In some examples, water can be used as the cleaning liquid. The cutting device 8 can use a pneumatic telescopic cutting device, which shrinks after cutting the PTFE tube, thereby avoiding contact with the PTFE tube during the traction process of the PTFE tube. The blowing device 10 can use a central hole blowing device, which can completely remove the residual cleaning liquid on the PTFE tube.

[0030] A first slide 7 is provided on one side of the cutting device 8, and a first clamping claw 4 is movably mounted on the first slide 7;

[0031] A second slide 5 is provided on the other side of the cutting device 8, and a second clamp 3 is movably mounted on the second slide;

[0032] The length directions of the first slide 7 and the second slide 5 are both parallel to the length directions of the cleaning tank and the etching tank 13 .

[0033] In the above embodiment, after one end of the PTFE tube to be processed is manually introduced into the etching tank 13 and the cleaning tank in turn, it is manually pulled through the blowing device 10, the clamping area 17 and the cutting device 8. After that, the first slide 7 and the second slide 5 can be controlled to work alternately, so that the first clamp 4 and the second clamp 3 alternately clamp the PTFE tube and pull it, which can improve the pulling efficiency of the PTFE tube. During the pulling process of the PTFE tube, it can pass through the etching tank 13 in turn to be etched, the cleaning tank to be cleaned, the blowing device 10 to remove the cleaning liquid remaining on the surface, and the cutting device 8 to cut off, so as to realize the assembly line processing of the PTFE tube, which is beneficial to improve the overall processing efficiency of the PTFE tube.

[0034] Taking the first clamping jaw 4 first clamping the PTFE tube as an example, in some examples, after the PTFE tube is manually pulled through the cutting device 8, the first slide 7 is controlled to work and the first clamping jaw 4 is moved to the clamping area 17, the first slide 7 stops working, the PTFE tube is clamped by the first clamp 4, and then the first slide 7 is controlled to work and the first clamp 4 moves in the opposite direction, away from the clamping area 17 at a preset speed. When the first clamp 4 reaches the initial position or pulls the PTFE tube through a preset length, the first slide 7 stops working, the cutting device 8 cuts off the PTFE tube, and the first clamp 4 is released. The cut PTFE tube; then control the second slide 5 to work and move the second jaw 3 to the clamping area 17, the second slide 5 stops working, clamps the PTFE tube by the second jaw 3, and then controls the second slide 5 to work and moves the second jaw 3 away from the clamping area 17 at a preset speed. When the second jaw 3 reaches the initial position or pulls the PTFE tube through a preset length, the second slide 5 stops working, the cutting device 8 cuts off the PTFE tube, and the second jaw 3 releases the cut PTFE tube; repeat the above process to achieve alternating traction of the first jaw 4 and the second jaw 3.

[0035] In some examples, the second clamping jaw 3 can be controlled to move toward the clamping area 17 while the first clamping jaw 4 is moving away from the clamping area 17, so that seamless connection of alternating traction can be achieved.

[0036] Reference Figure 3 As shown, in some examples, a pressure wheel 14 is movably installed on one side of the etching tank 13 and the cleaning tank, and the pressure wheel 14 can be raised and lowered perpendicular to the bottom of the etching tank 13 and the cleaning tank.

[0037] It should be noted that the pressure wheel 14 is rotatably connected to a lever structure, which includes a handle. By manually holding the handle and pressing it down or lifting it, the pressure wheel 14 can be raised or lowered. When introducing the PTFE tube, the pressure wheel 14 is controlled to be raised to facilitate the passage of the PTFE tube, and then the pressure wheel 14 is controlled to be lowered to press the PTFE tube into the etching solution or cleaning solution.

[0038] In the above embodiment, the pressing wheel 14 is kept in a lowered state during the processing to ensure that the PTFE tube is immersed in the etching liquid or the cleaning liquid. After the PTFE tube is replaced, the pressing wheel 14 is raised to facilitate manual guidance of the new PTFE tube to the clamping area 17.

[0039] Reference Figure 1 and Figure 3 As shown, in some examples, a guide wheel 18 is fixedly installed between the etching tank 13 and the cleaning tank, and at one end of the cleaning tank close to the blowing device 10, and the guide wheel 18 is higher than the etching tank 13 and the cleaning tank.

[0040] In the above embodiment, the guide wheel 18 can prevent the PTFE tube from contacting the etching tank 13 and the end of the cleaning tank during the traction process. The guide wheel 18 is rotatable to avoid damage to the outer wall of the PTFE tube.

[0043] In the above embodiment, the PTFE tube passes through the guide device 16, which can prevent the PTFE tube from bending or falling, and is conducive to the first clamping jaw 4 or the second clamping jaw 3 clamping the PTFE tube.

[0044] Reference Figure 1 and Figure 4As shown, in some examples, the first cylinder 1 is movably mounted on the first slide 7, and the first clamping jaw 4 is fixedly mounted on the movable end of the first cylinder 1;

[0045] The second cylinder 2 is movably mounted on the second slide 5 , and the second clamping jaw 3 is fixedly mounted on the movable end of the second cylinder 2 .

[0047] In the above embodiment, when the first jaw 4 or the second jaw 3 clamps the PTFE tube, the first cylinder 1 or the second cylinder 2 is in an extended state. When the first jaw 4 or the second jaw 3 releases the PTFE tube, the first cylinder 1 or the second cylinder 2 contracts. After the first jaw 4 or the second jaw 3 reaches the clamping area 17, the first cylinder 1 or the second cylinder 2 extends again to prevent the first jaw 4 or the second jaw 3 from contacting the PTFE tube during the non-traction movement.

[0048] Reference Figure 1 and Figure 3 As shown, in some examples, the device also includes a control device 9, which is electrically connected to the first slide 7, the second slide 5, the first cylinder 1, the second cylinder 2, the first clamp 4, the second clamp 3, the blowing device 10 and the cutting device 8 respectively.

[0055] In other examples, the storage bin 6 can also be movably installed on the stand 19. After it receives a certain number of PTFE tubes, the storage bin 6 can be replaced, thereby realizing the batch transportation of PTFE tubes.

[0056] In the above embodiment, the PTFE tube can be cleaned twice after etching, which has a better cleaning effect and can avoid the problem of residual etching solution. The guide wheel 18 can also prevent the PTFE tube from contacting the groove end and causing wear.
