[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0028] As Figures 1 - 6As shown in the figure, a production method and device for a high-temperature resistant and enhanced adhesion tape, including the following operating steps:

[0029] S1. Surface activation of the PTFE substrate with a power of 300 W and a treatment time of 60 seconds to improve the adhesive adhesion; for the fiberglass cloth, apply an epoxy resin primer with a thickness of 3 μm and dry it at 80 °C for 5 minutes; mix the resin, solvent, and filler according to the formula and stir in the housing 1 for 2 hours until uniform;

[0030] S2. Coating speed: 20 m / min, wet glue thickness: 100 μm; drying in segments at 120 °C for 5 minutes to ensure complete volatilization of the solvent; compound release paper on the surface of the glue layer with a pressure of 0.3 MPa to avoid air bubbles; place it in a curing chamber at 50 °C and let it stand for 48 hours to promote the cross-linking of the adhesive;

[0031] S3. Cut it into a width of 10 mm with a round knife cutter, and control the tension ≤ 2 N; the winding tension is uniform to avoid tape deformation; package it in a moisture-proof aluminum foil bag, and the storage temperature is 15 - 25 °C, humidity ≤ 60%.

[0032] A production device for a high-temperature resistant and enhanced adhesion tape; a motor 2 is fixedly connected to the top end of the housing 1; a conveying pipe 3 is fixedly connected to the top end of the housing 1; the output end of the motor 2 is fixedly connected to a stirring rod 4; stirring blades 5 are fixedly connected to the outer side wall of the stirring rod 4; a first cylinder 6 is fixedly connected to the inside of the stirring rod 4; a rack plate 7 is fixedly connected to the bottom end of the first cylinder 6; a gear 8 is rotatably connected to the inside of the stirring rod 4, and the gear 8 meshes with the rack plate 7; a rotating blade 9 is fixedly connected to the side end of the gear 8.

[0033] During operation, materials are conveyed to the housing 1 through the conveying pipe 3, the stirring rod 4 is rotated by the motor 2, and the rotation of the stirring rod 4 causes the stirring blades 5 to rotate to stir and mix the materials inside the housing 1. The first cylinder 6 can move the rack plate 7 up and down. The rack plate 7 meshes with the gear 8, and the movement of the rack plate 7 causes the gear 8 to rotate. The rotation of the gear 8 further causes the rotating blade 9 to rotate together. The rotating direction of the rotating blade 9 is different from that of the stirring blade 5, thereby improving the stirring and mixing effect of the materials inside the housing 1, so as to meet the mixing effect of the tape materials.

[0034] A connecting air pipe 11 is fixedly connected to one side of the conveying pipe 3 at the top end of the housing 1; an air suction pump 12 is fixedly connected to the side end of the connecting air pipe 11; a filter box 13 is fixedly connected to the side end of the air suction pump 12; a frame body 17 is installed inside the filter box 13; a first filter strip 18 is fixedly connected to the inside of the frame body 17; a second filter strip 24 is fixedly connected to one side of the first filter strip 18 inside the frame body 17; a sealing cover 14 is installed at the top end of the filter box 13.

[0035] After the waste gas enters the interior of the filter box 13, it will be absorbed by the first filter strip 18. The first filter strip 18 and the second filter strip 24 are made of filter cotton. Filter cotton is a fibrous material used to filter impurities in liquids or gases, which can filter harmful gases in the waste gas, thereby reducing environmental pollution caused by harmful gases. The frame 17 needs to be maintained regularly to ensure the filtering effect. Opening the sealing cover 14 facilitates the disassembly of the frame 17;

[0036] The interior of the filter box 13 is rotatably connected with a spiral blade 15; a cleaning brush 16 is fixedly connected to the side end of the spiral blade 15, and the cleaning brush 16 is arranged on one side of the first filter strip 18.

[0037] During the stirring process of the material inside the housing 1, a large amount of harmful waste gas will be generated. Through the suction pump 12, the waste gas inside the housing 1 can be transported to the connecting air pipe 11. The waste gas enters the interior of the filter box 13 through the suction pump 12. After the waste gas enters the interior of the filter box 13, it drives the spiral blade 15 to rotate. The rotation of the spiral blade 15 further causes the cleaning brush 16 to rotate together. The rotation of the spiral blade 15 can disperse the waste gas inside the filter box 13, preventing the waste gas from being concentrated and transported to the first filter strip 18. The rotation of the cleaning brush 16 can clean the dust particles accumulated on the surface, ensuring the flow of the waste gas;

[0038] A second cylinder 19 is fixedly connected inside the frame 17; a sliding rod 26 is fixedly connected to the side end of the second cylinder 19; a support plate 20 is fixedly connected to the side end of the sliding rod 26; a first vibration block 21 is fixedly connected to the side end of the support plate 20; a second vibration block 22 is fixedly connected inside the first filter strip 18, and the second vibration block 22 is arranged on one side of the first vibration block 21.

[0039] There are multiple groups of first filter strips 18 inside the filter box 13. Multiple groups of first filter strips 18 can improve the filtering effect. However, after long-term use, the first filter strip 18 will adsorb harmful particles in the waste gas and thus become blocked, affecting the waste gas filtering effect. Through the second cylinder 19, the sliding rod 26 slides. The sliding of the sliding rod 26 further causes the support plate 20 and the first vibration block 21 to slide. The sliding of the first vibration block 21 can impact the second vibration block 22, causing the second vibration block 22 to vibrate. The vibration effect of the second vibration block 22 will be transmitted to the first filter strip 18, and then the particles adsorbed on the upper surface of the first filter strip 18 will be vibrated and dropped. Through the second cylinder 19, the first filter strip 18 can be vibrated repeatedly to ensure the filtering effect of the first filter strip 18 and extend the effective service life of the first filter strip 18;

[0040] Multiple groups of activated carbon 23 are arranged inside the first filter strip 18; multiple groups of first filter strips 18 are arranged inside the frame 17, and the positions of the activated carbon 23 in each group of first filter strips 18 are different.

[0041] Activated carbon 23 is installed inside each first filter strip 18. The use of activated carbon 23 can improve the filtering effect of the first filter strip 18. The positions of the activated carbon 23 in each group of first filter strips 18 are different. When the waste gas passes through a group of activated carbon 23, it must take a detour to flow. The different positions of the activated carbon 23 can improve the purification effect of the waste gas;

[0042] A groove 25 is formed inside the frame body 17; the groove 25 is provided on one side of the bottom end of the first filter strip 18.

[0043] The groove 25 is provided on one side of the first filter strip 18. After the first vibration block 21 vibrates the second vibration block 22, the dust particles will fall downward. The groove 25 can collect the particles, reducing the accumulation of dust particles at the bottom of the frame body 17 and affecting the flow of the waste gas;

[0044] A scraping wall plate 10 is fixedly connected to the side end of the stirring rod 4, and the scraping wall plate 10 is rotatably connected to the inner side wall of the housing 1.

[0045] The rotation of the stirring rod 4 causes the scraping wall plate 10 to rotate. The rotation of the scraping wall plate 10 will generate friction with the inner side wall of the housing 1, thereby scraping off the materials adsorbed on the inner side wall of the housing 1, preventing the materials from being continuously adsorbed on the inner side wall of the housing 1 and unable to be mixed.

[0046] Working principle of the present invention: During operation, materials are conveyed to the housing 1 through the conveying pipe 3. The stirring rod 4 is rotated by the motor 2, and the rotation of the stirring rod 4 causes the stirring blades 5 to rotate, thereby stirring and mixing the materials inside the housing 1. The rack plate 7 can be moved up and down by the first cylinder 6. The rack plate 7 meshes with the gear 8, and the movement of the rack plate 7 causes the gear 8 to rotate. The rotation of the gear 8 further causes the rotary blade 9 to rotate together. The rotary blade 9 rotates in a direction different from that of the stirring blade 5, thereby improving the stirring and mixing effect of the materials inside the housing 1, so as to meet the mixing effect of the tape materials; the rotation of the stirring rod 4 causes the scraping wall plate 10 to rotate, and the rotation of the scraping wall plate 10 will generate friction with the inner side wall of the housing 1, thereby scraping off the materials adsorbed on the inner side wall of the housing 1, preventing the materials from being continuously adsorbed on the inner side wall of the housing 1 and unable to be mixed; a large amount of harmful waste gas will be generated during the stirring process of the materials inside the housing 1. The waste gas inside the housing 1 can be conveyed to the connecting air pipe 11 through the suction pump 12. The waste gas enters the interior of the filter box 13 through the suction pump 12. After the waste gas enters the interior of the filter box 13, it drives the spiral blade 15 to rotate. The rotation of the spiral blade 15 further causes the cleaning brush 16 to rotate together. The rotation of the spiral blade 15 can disperse the waste gas inside the filter box 13, preventing the waste gas from being concentrated and conveyed to the first filter strip 18. The rotation of the cleaning brush 16 can clean the dust particles accumulated on the surface, ensuring the flow of the waste gas; the waste gas entering the interior of the filter box 13 will be absorbed by the first filter strip 18. The first filter strip 18 and the second filter strip 24 are made of filter cotton material. Filter cotton is a fibrous material used to filter impurities in liquids or gases, which can filter harmful gases in the waste gas, thereby reducing environmental pollution caused by harmful gases. The frame 17 needs to be maintained regularly to ensure the filtering effect. The sealing cover 14 is opened to facilitate the disassembly of the frame 17; multiple groups of first filter strips 18 are provided inside the filter box 13. Multiple groups of first filter strips 18 can improve the filtering effect. However, after long-term use, the first filter strip 18 will adsorb harmful particles in the waste gas and become blocked, affecting the waste gas filtering effect. The sliding rod 26 is slid by the second cylinder 19. The sliding of the sliding rod 26 further causes the support plate 20 and the first vibration block 21 to slide. The sliding of the first vibration block 21 can impact the second vibration block 22, thereby causing the second vibration block 22 to vibrate. The vibration effect of the second vibration block 22 will be transmitted to the first filter strip 18, and then the particles adsorbed on the upper surface of the first filter strip 18 will be vibrated and dropped. The first filter strip 18 can be vibrated repeatedly through the second cylinder 19 to ensure the filtering effect of the first filter strip 18 and extend the effective service life of the first filter strip 18; activated carbon 23 is installed inside each group of first filter strips 18. The filtering effect of the first filter strip 18 can be improved through the activated carbon 23. The positions of the activated carbon 23 in each group of first filter strips 18 are different. When the waste gas passes through a group of activated carbon 23, it must take a detour to flow. The different positions of the activated carbon 23 can improve the purification effect of the waste gas;The groove 25 is provided on one side of the first filter strip 18. After the first vibration block 21 vibrates the second vibration block 22, the dust particles will fall downward. The groove 25 can collect the particles, reducing the accumulation of dust particles at the bottom of the frame 17 and affecting the flow of waste gas.
