Description

Technical Field

[0001] The invention relates to the technical field of film production, and in particular to a surface impurity cleaning device and a cleaning method for elastic waterproof PTFE film production. Background Art

[0002] Polytetrafluoroethylene (PTFE) is a self-lubricating material with an extremely low friction coefficient and excellent corrosion resistance. It is widely used in the aerospace and defense industries, but its wear resistance is poor. In order to more effectively utilize the sliding properties of PTFE and better exert its oil-free lubrication and sealing properties, glass fiber is usually used as the fabric substrate. PTFE film is produced in this way, and film products need to be rolled up after production.

[0003] At present, when producing elastic waterproof PTFE film, it is necessary to clean the dust on the surface before rolling it up. However, when rolling up, the films are overlapped with each other, which will generate an internal tightening force in the direction of the axis of the winding roller and act between the bonding surfaces of the films, which can easily cause the elastic films to stick to each other and make it difficult to separate them later.

[0014] The present invention also provides a method for cleaning impurities on the surface of an elastic waterproof PTFE film for production, which is applied to a device for cleaning impurities on the surface of an elastic waterproof PTFE film for production. The method for cleaning impurities on the surface of an elastic waterproof PTFE film for production comprises the following steps: Step S1: Pass one end of the PTFE film to be rolled up through the winding channel and then wind it on the winding drum, then roll up and pull the PTFE film by rotating the winding drum. Before rolling up, the conveying and pressing force of the conveying component on the PTFE film can be changed by the adjusting component. At the same time, the outer surface of the PTFE film is coated with lubricating oil during transportation to form a thin oil film on the outer surface of the PTFE film to avoid the subsequent adhesion of the PTFE film due to mutual overlap after rolling up. When the driving adjusting component adjusts the conveying component, it also triggers the connecting component to control the supply of lubricating oil. Step S2: When the adjustment component is working, the adjustment sleeve is rotated to make one end of the umbrella cover slide toward the side wall of the protective shell. During the sliding process, the inner arc surface of the umbrella cover and the arc surface of the triangular arc block fit each other, so that the triangular arc block can be pressed downward to drive the conveying component to slide downward; Step S3: When the connection assembly is working, when the triangular arc block slides downward, it will drive the reciprocating plate to slide downward. When it slides to the bottom, the constraint on the contact rod will be released. Under the elastic force of the adjustment spring, the adjustment block slides to one side, so that the filter port slides to the bottom of the hose, thereby connecting the bottom of the hose and the filter port. At the same time, the filter port is also connected to the feed channel, so that the lubricating oil can be injected into the storage cavity through the hose; Step S4: When the conveying component is working, when the conveying roller rotates, the bending hole will introduce the solution inside the drainage channel into the hollow cavity each time it passes one end of the drainage channel. Therefore, the end of the conveying roller engaged in the card cavity will intermittently convey the oil inside the drainage channel to the hollow cavity, and then flow to the felt sleeve through the throttling hole, so that the outer surface of the PTFE film can be coated when conveying the film to form an oil film on the outer surface, and at the same time, the dust on the outer surface of the film can be adsorbed and removed.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention allows one end of the PTFE film to be rolled up to pass through a winding channel and then be wound around a winding drum. The PTFE film is then rolled up and pulled by rotating the winding drum. Before rolling up, the conveying and pressing force of the conveying assembly on the PTFE film can be changed by an adjusting assembly. At the same time, lubricating oil is coated on the outer surface of the PTFE film during transportation to form a thin oil film on the outer surface of the PTFE film, thereby preventing the PTFE films from being stacked and sticking to each other after subsequent rolling up. When the driving adjusting assembly adjusts the conveying assembly, the connecting assembly is also triggered to control the supply of lubricating oil. 2. In the present invention, when the adjustment component is working, the adjustment sleeve is rotated to make one end of the umbrella cover slide toward the side wall of the protective shell. During the sliding process, the inner arc surface of the umbrella cover and the arc surface of the triangular arc block fit each other, and then the triangular arc block can be pressed downward to drive the conveying component to slide downward. When the triangular arc blocks are arranged inside the upper and lower openings of the external threaded tube, the control parts of the two conveying components can be docked. When the adjustment sleeve is driven, the two conveying components can be driven to move relative to each other, thereby adjusting the pressing force on the PTFE film during conveying; 3. In the present invention, when the connection assembly is working, when the triangular arc block slides downward, it will drive the reciprocating plate to slide downward. When it slides to the bottom, the constraint on the contact rod will be released, and the adjustment block will slide to one side under the elastic force of the adjustment spring, so that the filter port slides to the bottom of the hose, thereby connecting the bottom of the hose and the filter port to each other; 4. In the present invention, when the conveying component is working, when the conveying roller rotates, the bending hole will introduce the solution inside the drainage channel into the hollow cavity each time it passes through one end of the drainage channel. Therefore, the conveying roller engaged in one end of the card cavity will intermittently convey the oil inside the drainage channel to the hollow cavity, and then flow to the felt sleeve through the throttling hole, so that the outer surface of the PTFE film can be coated when conveying the film to form an oil film on the outer surface.

[0022] The effect achieved is that by rotating the adjusting sleeve 8, one end of the umbrella cover 9 slides toward the side wall of the protective shell 1. During the sliding process, the inner arc surface of the umbrella cover 9 fits with the arc surface of the triangular arc block 16, and then the triangular arc block 16 can be pressed downward to drive the conveying component to slide downward. When the triangular arc blocks 16 are arranged inside the upper and lower openings of the external threaded tube 15, the control parts of the two conveying components can be connected. When driving the adjusting sleeve 8, the two conveying components can be driven to move relative to each other, thereby adjusting the clamping force on the PTFE film during transportation.

[0023] like Figure 4 , Figure 5 , Figure 6 , Figure 8 , Fig. 9 and Fig.10As shown, the connection assembly includes an adjustment block 27, an adjustment chamber 26 is provided inside the protective housing 1 near the side of the slide groove 23, the adjustment block 27 is slidably connected between the inner walls of the adjustment chamber 26, a transition chamber 28 is provided inside the adjustment block 27, and the inner wall of the transition chamber 28 is provided with a plurality of filter ports 29 that penetrate to the outside at equal intervals along the circumferential direction, contact rods 31 are fixed on both sides of the adjustment block 27, an adjustment spring 30 is fixed on one side of the adjustment block 27, one end of the adjustment spring 30 is fixed on one inner wall of the adjustment chamber 26, and the contact rod 31 near the side of the slide groove 23 penetrates to the slide groove 23, and is engaged in the positioning groove 22, a hose 10 is fixed on the top of the protective shell 1, the bottom of the hose 10 passes through the inside of the adjusting cavity 26, and the bottom of the hose 10 is communicated with the filter port 29, a storage cavity 32 is provided inside the protective shell 1, a feed channel 34 is provided on one side of the storage cavity 32 near the top edge, one end of the feed channel 34 passes through the inside of the storage cavity 32 and is opposite to the filter port 29, a side hole 33 is provided on one side of the storage cavity 32 at the middle, the side hole 33 passes through to the rear side of the slide groove 23, and is communicated with the drainage channel 24.

[0024] The effect achieved is that when the adjustment component is not working, the reciprocating plate 19 is located above the inside of the reciprocating chamber 18. At this time, the reciprocating spring 20 has a small amount of upward pulling force on the reciprocating plate 19, and one end of the contact rod 31 that penetrates into the reciprocating chamber 18 fits with the outer surface of the reciprocating plate 19. At this time, the bottom of the hose 10 fits with the outer surface of the adjustment block 27. The filter port 29 is located on one side of the bottom of the hose 10, and one end of the feed channel 34 is also located on one side of the filter port 29. Therefore, at this time, the feed channel 34 and the hose 10 cannot be connected through the filter port 29. At this time, the adjustment spring 30 is in a compressed state. When the triangular arc block 16 slides downward, it will drive the reciprocating plate 19 to slide downward.

[0025] like Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Fig. 9 and Fig.10As shown, the adjustment assembly includes a reciprocating plate 19, a reciprocating cavity 18 is provided inside the protective shell 1, the reciprocating plate 19 is slidably connected between the inner walls of the reciprocating cavity 18, side openings 17 are provided on both sides of the inner walls of the reciprocating cavity 18, one of the side openings 17 penetrates into the interior of the slide groove 23, and the other side opening 17 penetrates to the outside of the protective shell 1, a reciprocating spring 20 is fixed between the top of the reciprocating plate 19 and the inner top surface of the reciprocating cavity 18, one end of another contact rod 31 penetrates into the interior of the reciprocating cavity 18, and an externally threaded pipe 15 is fixed to the outside of the protective shell 1, and the externally threaded pipe 15 is fixed to the outside of the protective shell 1. 5 is threadedly connected with an adjusting sleeve 8 near one end edge, and an umbrella-shaped cover 9 is fixed to the outer surface of the adjusting sleeve 8 near one side edge.

When it slides to the point where the drainage channel 24 is opposite to the side hole 33, the lubricating oil liquid inside the storage chamber 32 can enter the interior of the drainage channel 24 through the side hole 33. When the conveying roller 11 rotates, the bending hole 25 will introduce the solution inside the drainage channel 24 into the hollow cavity 12 each time it passes through one end of the drainage channel 24. Therefore, the end of the conveying roller 11 that is engaged in the card cavity 35 will intermittently transport the oil inside the drainage channel 24 to the interior of the hollow cavity 12, and then flow from the throttling hole 13 to the felt sleeve 14, so that the outer surface of the film can be coated when the PTFE film is conveyed to form an oil film on the outer surface.

[0027] For example, in one embodiment, the present invention further provides a method for cleaning impurities on the surface of an elastic waterproof PTFE film for production, which is applied to a device for cleaning impurities on the surface of an elastic waterproof PTFE film for production as described above, comprising the following steps: Step S1: Pass one end of the PTFE film to be rolled up through the winding channel 2 and then wind it on the winding drum 5, then roll up and pull the PTFE film by rotating the winding drum 5. Before rolling up, the conveying pressing force of the conveying component on the PTFE film can be changed by the adjusting component. At the same time, the outer surface of the PTFE film is coated with lubricating oil during transportation to form a thin oil film on the outer surface of the PTFE film to avoid the subsequent adhesion of the PTFE film due to mutual overlap after rolling up. When the driving adjusting component adjusts the conveying component, it also triggers the connecting component to control the supply of lubricating oil. Step S2: When the adjustment component is working, the adjustment sleeve 8 is rotated to make one end of the umbrella cover 9 slide toward the side wall of the protective housing 1. During the sliding process, the inner arc surface of the umbrella cover 9 fits with the arc surface of the triangular arc block 16, and then the triangular arc block 16 can be pressed downward to drive the conveying component to slide downward; Step S3: When the connection assembly is working, when the triangular arc block 16 slides downward, it will drive the reciprocating plate 19 to slide downward. When sliding to the bottom, the constraint on the contact rod 31 will be released. Under the elastic force of the adjustment spring 30, the adjustment block 27 slides to one side, so that the filter port 29 slides to the bottom of the hose 10, so that the bottom of the hose 10 and the filter port 29 are connected to each other. At the same time, the filter port 29 is also connected to the feed channel 34, so that the lubricating oil can be injected into the storage chamber 32 through the hose 10; Step S4: When the conveying component is working, when the conveying roller 11 rotates, the bending hole 25 will introduce the solution inside the drainage channel 24 into the hollow cavity 12 each time it passes through one end of the drainage channel 24. Therefore, the end of the conveying roller 11 that is engaged in the card cavity 35 will intermittently convey the oil inside the drainage channel 24 to the hollow cavity 12, and then flow to the felt sleeve 14 through the throttling hole 13, so that the outer surface of the PTFE film can be coated when conveying the film to form an oil film on the outer surface, and at the same time, the dust on the outer surface of the film can be adsorbed and removed.

10. A method for cleaning impurities on the surface of an elastic waterproof PTFE film for production, which is applied to a device for cleaning impurities on the surface of an elastic waterproof PTFE film for production as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: Step S1: one end of the PTFE film to be rolled up is passed through the winding channel (2) and then wound onto the winding drum (5), and then the PTFE film is rolled up and pulled by the rotation of the winding drum (5). Before rolling up, the conveying pressing force of the conveying component on the PTFE film can be changed by the adjusting component. At the same time, the outer surface of the PTFE film is coated with lubricating oil during transportation, so that a thin oil film is formed on the outer surface of the PTFE film to prevent the PTFE film from overlapping and sticking to each other after subsequent rolling up. When the driving adjusting component adjusts the conveying component, it also triggers the connecting component to control the supply of lubricating oil; Step S2: When the adjustment component is working, the adjustment sleeve (8) is rotated to make one end of the umbrella cover (9) slide toward the side wall of the protective housing (1). During the sliding process, the inner arc surface of the umbrella cover (9) and the arc surface of the triangular arc block (16) fit each other, so that the triangular arc block (16) can be pressed downward, so that it drives the conveying component to slide downward; Step S3: When the connection assembly is working, when the triangular arc block (16) slides downward, it drives the reciprocating plate (19) to slide downward. When sliding to the bottom, the constraint on the contact rod (31) is released. Under the elastic force of the adjustment spring (30), the adjustment block (27) slides to one side, so that the filter port (29) slides to the bottom of the hose (10), thereby connecting the bottom of the hose (10) and the filter port (29). At the same time, the filter port (29) is also connected to the feed channel (34), so that the lubricating oil can be injected into the storage chamber (32) through the hose (10); Step S4: When the conveying assembly is working, when the conveying roller (11) rotates, the bent hole (25) will introduce the solution inside the drainage channel (24) into the hollow cavity (12) each time it passes through one end of the drainage channel (24). Therefore, the end of the conveying roller (11) that is engaged in the card cavity (35) will intermittently convey the oil inside the drainage channel (24) to the inside of the hollow cavity (12), and then flow to the felt sleeve (14) through the throttling hole (13), so that the outer surface of the PTFE film can be coated when the film is conveyed to form an oil film on the outer surface, and at the same time, the dust on the outer surface of the film can be adsorbed and removed.
