Description

Technical Field

[0001] This invention relates to the field of impregnation equipment technology, and in particular to an impregnation device and method for producing epoxy mesh fabric. Background Technology

[0002] Epoxy mesh fabric is formed by high-temperature dehydration of a mesh prefabricated fabric with square holes, impregnating it with epoxy resin, and then drying and curing it. The impregnation process is a post-treatment technique that ensures thorough wetting of the machine structure and good adhesive adhesion. Impregnating the mesh prefabricated fabric improves its application performance, such as increasing its temperature resistance and maintaining high mechanical strength at high temperatures, ensuring the normal operation of equipment under high-temperature conditions.

[0003] For example, utility model CN214572965U discloses an impregnation device for epoxy mesh fabric production, including a control box and an impregnation tank. A roller assembly is connected to the side wall of the control box, and the roller assembly cooperates with the impregnation tank. The roller assembly includes an impregnation roller disposed in the impregnation tank, and a first transmission roller and a second transmission roller disposed above the impregnation tank. The projections of the first transmission roller, the impregnation roller, and the second transmission roller on the vertical plane are distributed in a V-shape. An air nozzle is disposed between the impregnation roller and the second transmission roller. A scraper is disposed above the air nozzle. A return temperature box and a third transmission roller are disposed sequentially on the side of the second transmission roller away from the first transmission roller. A temperature regulating mechanism is disposed on the return temperature box. This utility model provides an impregnation device for epoxy mesh fabric production that can remove the adhesive film, save materials, and is easy to clean.

[0004] The above-mentioned technical solution still has some shortcomings in its application:

[0005] In the above technical solution, the air nozzle blows air directly onto the mesh of the mesh to break the adhesive film in the mesh. However, since a lot of epoxy resin adheres to the mesh after it leaves the impregnation tank, the adhesive film in the mesh is relatively thick, making it difficult for the air nozzle to completely break the adhesive film on the mesh.

[0006] The adhesive film in the mesh is blown apart by the nozzle, making it impossible to inspect the mesh fabric. However, the adhesive film remains in the mesh, which affects the quality of the mesh fabric in the later stages.

[0007] Excess epoxy resin on the surface of the mesh fabric is scraped off with a scraper. This can lead to uneven epoxy resin adhesion and insufficient flatness during the subsequent drying process, affecting the aesthetics and quality of the mesh fabric.

[0008] To address the aforementioned problems, this invention proposes an impregnation device and method for producing epoxy mesh fabric. Summary of the Invention

[0009] This invention provides an impregnation device and method for producing epoxy mesh fabric, which solves the shortcomings of the prior art, such as difficulty in blowing through the adhesive film on the mesh fabric, inability to inspect the mesh fabric, uneven epoxy resin adhesion thickness, and insufficient flatness.

[0010] This invention provides the following technical solution:

[0011] An impregnation device for producing epoxy mesh fabric includes: a frame, in which a first conveying roller, a second conveying roller, a third conveying roller, a first coating roller, a second coating roller, and a take-up roller are rotatably connected, and an impregnation tank is provided in the frame below the second and third conveying rollers;

[0012] The frame is fixedly connected to a base plate box and a heating box. The base plate box is located below the heating box. The top of the heating box is equipped with multiple blowers. Multiple heating elements are fixedly connected to the inner walls of the heating box on opposite sides.

[0013] An impregnation structure, located inside the impregnation tank, is used to ensure that the epoxy resin can fully impregnate the mesh fabric;

[0014] The cleaning structure, located inside the frame, is used to remove the adhesive film contained within the mesh of the mesh fabric;

[0015] A uniform structure, set inside the frame, is used to ensure that the epoxy resin on the surface of the mesh fabric is applied evenly.

[0016] The detection structure, located at the bottom of the base box, is used to detect whether the adhesive film contained in the mesh fabric has been removed to the required standard.

[0017] In one possible design, the impregnation structure includes two impregnation rollers rotatably connected within an impregnation chamber. A U-shaped frame is slidably connected within the impregnation chamber between the two impregnation rollers. A rotating roller for stretching the mesh fabric is rotatably connected within the U-shaped frame. Multiple first springs are fixedly connected to both sides of the top of the impregnation chamber, and the top ends of the multiple first springs on the same side are fixedly connected to the U-shaped frame. Connecting plates are fixedly connected to both sides of the top of the U-shaped frame. When the mesh fabric enters the impregnation chamber, the rotating shaft drives the cam to rotate. The cam pushes the U-shaped frame to move up and down reciprocally through the connecting plates. The rotating roller can drive the mesh fabric between the two impregnation rollers to move up and down, exerting a certain pulling effect on the mesh fabric, so that the epoxy resin can fully impregnate the mesh fabric and ensure the impregnation effect of the epoxy resin.

[0018] In one possible design, the cleaning structure includes a rotating shaft rotatably connected within the frame, positioned above a connecting plate. Multiple push plates for vibrating the mesh fabric are fixedly fitted onto the outer wall of the rotating shaft. Two cams are also fixedly fitted onto the outer wall of the rotating shaft, located on either side of the push plates. The cams engage with the connecting plate. A rotating scraper is rotatably connected within the impregnation tank, engaging with a second conveying roller. When the second conveying roller conveys the impregnated mesh fabric, one side of the rotating scraper initially scrapes away the epoxy resin contained in the mesh fabric on the surface of the second conveying roller, preventing excessive epoxy resin from affecting the subsequent removal of the adhesive film in the mesh. The rotating shaft drives the push plates to rotate, causing the mesh fabric to vibrate up and down, breaking the residual adhesive film in the mesh holes.

[0019] In one possible design, the uniform structure includes two U-shaped sliding plates slidably connected within the frame. Multiple third springs are fixedly connected to the opposite sides of the two U-shaped sliding plates, and the other end of each third spring is fixedly connected to an inner wall of the frame. A hollow coating tube for compressing the mesh fabric is fixedly connected inside each third spring. Multiple air outlets are provided on the side of the hollow coating tube away from the third springs for blowing hot air through the mesh fabric. When the mesh fabric passes through the first and second coating rollers, the two hollow coating tubes, under the action of the third springs, tightly compress the mesh fabric, further scraping away any residual epoxy resin. The two hollow coating tubes can also evenly spread the epoxy resin onto the mesh fabric. Hot air blown by the blower enters the hollow coating tube through the exhaust pipe and is blown obliquely upwards through the air outlets, initially solidifying the epoxy resin on the mesh fabric and preventing uneven impregnation of the mesh fabric surface due to epoxy resin flow during later transport.

[0020] In one possible design, the detection structure includes two exhaust pipes fixedly connected to the bottom of a base box, with the other ends of each exhaust pipe connected to a corresponding hollow coating pipe. Multiple pads for supporting the mesh fabric are fixedly connected inside the base box. A rotating shaft rotatably passes through each exhaust pipe, and a turbine located inside the exhaust pipe is fixedly fitted onto the outer wall of the rotating shaft. Two connecting blocks are fixedly connected to one side of the exhaust pipe, with the connecting blocks located on both sides of the rotating shaft. An S-pole magnet and an N-pole magnet are fixedly connected to the sides of the two connecting blocks that are close to each other. A fixing ring is fixedly sleeved on the outer wall of the shaft. A magnetic field line cutting coil for cutting the magnetic induction lines between the S-pole magnet and the N-pole magnet is fixedly connected to one side of the fixing ring. When the mesh cloth enters between the bottom plate box and the heating box, the blower blows the air heated by the heating element onto the mesh cloth to dry it. The hot air enters the exhaust pipe through the mesh inside the mesh cloth. The hot air can quickly drive the rotating shaft to rotate. The magnetic field line cutting coil cuts the magnetic induction lines between the S-pole magnet and the N-pole magnet, energizing the electromagnet. The strength of the electromagnet's magnetic force is then used to detect the presence of the adhesive film in the mesh cloth.

[0021] In one possible design, the detection structure further includes a third magnet fixedly connected to one side of the top of the frame. An electromagnet is slidably connected to one side of the top of the frame. A tension spring is fixedly connected between the electromagnet and the third magnet. A first metal contact and a second metal contact are fixedly connected between the electromagnet and the third magnet, respectively. An alarm light is fixedly connected to one side of the top of the frame, and the first and second metal contacts are electrically connected to the alarm light. A closed circuit is formed between the electromagnet and the magnetic field line cutting coil. The magnetic field line cutting coil cuts the magnetic field between the S-pole magnet and the N-pole magnet. The induction wire and the strong current of the electromagnet cause the repulsive force between the electromagnet and the third magnet to be greater than the tension of the spring. The first and second metal contacts disengage. When there is still adhesive film in the mesh of the mesh cloth, less hot air enters the exhaust pipe, the rotation speed of the rotating shaft slows down, the speed at which the magnetic induction wire cutting coil cuts the magnetic induction wire decreases, the current in the electromagnet decreases, and the repulsive force between the electromagnet and the third magnet is less than the tension of the spring. The first and second metal contacts then touch, and the alarm light is powered on, making it easier for staff to carry out maintenance and preventing the mesh cloth carrying adhesive film from being wound up by the winding roller.

[0022] In one possible design, a fixed horizontal plate is fixedly connected inside the frame. A plurality of second springs are fixedly connected to the side of the fixed horizontal plate near the third conveying roller. The other end of the plurality of second springs is fixedly connected to the same arc-shaped scraper, and the arc-shaped scraper is slidably connected inside the frame. The arc-shaped scraper cooperates with the third conveying roller. The adhesive film remaining in the mesh holes is broken by vibration, and the broken adhesive film still remains on the surface of the mesh fabric. Under the elastic force of the second springs, the arc-shaped scraper is tightly pressed against the third conveying roller, and the arc-shaped scraper can scrape off the adhesive film on the surface of the mesh fabric again.

[0023] In one possible design, a plurality of second magnets are fixedly connected to one inner wall of the impregnation tank, and a plurality of first magnets are fixedly embedded on the side of the rotating scraper near the second magnets; when the second conveying roller conveys the impregnated mesh fabric, the epoxy resin contained in the mesh fabric on the surface of the second conveying roller is initially scraped off by the magnetic repulsion between the first magnets and the second magnets on one side of the rotating scraper.

[0024] In one possible design, an arc-shaped plate is fixedly connected to the bottom of the hollow coating tube, and a rotating rod is rotatably connected inside the arc-shaped plate. An impregnation wheel is fixedly fitted on the outer wall of the rotating rod, and a baffle is fixedly connected to the top of the arc-shaped plate, with the baffle contacting the outer wall of the impregnation wheel. When the two hollow coating tubes work together to evenly coat the epoxy resin in the mesh fabric, excess epoxy resin scraped off the hollow coating tube falls onto the arc-shaped plate along the outer wall of the hollow coating tube. At this time, the two impregnation wheels are driven by a motor to rotate in opposite directions, and the impregnation wheels evenly coat the epoxy resin accumulated on the arc-shaped plate onto the mesh fabric, further ensuring the uniformity of epoxy resin coating on the mesh fabric.

[0025] The method of using the impregnation equipment for producing epoxy mesh fabric includes the following steps:

[0026] S1. The rotating shaft pushes the connecting plate and the U-shaped frame to move up and down repeatedly through the cam, and the rotating roller pulls the mesh cloth to a certain extent so that the epoxy resin can fully impregnate the mesh cloth.

[0027] S2. Rotate one side of the scraper to initially scrape off the epoxy resin contained in the mesh cloth on the surface of the second conveyor roller;

[0028] S3. The rotating shaft drives the pusher plate to rotate, and the pusher plate can drive the mesh cloth to vibrate up and down, breaking the residual adhesive film in the mesh holes. The arc-shaped scraper scrapes off the adhesive film on the surface of the mesh cloth under the action of the second spring.

[0029] S4. Under the action of the third spring, the two hollow coating tubes further scrape off the residual epoxy resin on the mesh cloth and evenly spread the epoxy resin on the mesh cloth. The hot air in the hollow coating tubes initially solidifies the epoxy resin on the mesh cloth through the air outlet.

[0030] S5. The mesh cloth is dried by the blower. Hot air enters the exhaust pipe and the rotating shaft rotates. The magnetic induction wire cuts the magnetic field and energizes the electromagnet. The hot air entering the exhaust pipe is smaller and the current decreases. The first metal contact and the second metal contact touch, and the alarm light is energized.

[0031] S6. Two impregnation wheels are driven by a motor to rotate in opposite directions. The impregnation wheels evenly apply the epoxy resin gathered on the arc plate onto the mesh cloth.

[0032] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0033] In this invention, the outer wall of the rotating shaft is fixedly fitted with multiple push plates for vibrating the mesh fabric, and the outer wall of the rotating shaft is fixedly fitted with two cams. A rotating scraper is rotatably connected inside the impregnation tank, and the rotating scraper cooperates with the second conveying roller. When the second conveying roller conveys the impregnated mesh fabric, one side of the rotating scraper initially scrapes off the epoxy resin contained in the mesh fabric on the surface of the second conveying roller, so as to avoid the excessive epoxy resin in the mesh fabric affecting the removal of the adhesive film in the mesh later. The rotating shaft drives the push plates to rotate, driving the mesh fabric to vibrate up and down, breaking the adhesive film remaining in the mesh holes.

[0034] In this invention, multiple third springs are fixedly connected to the opposite sides of the two U-shaped sliding plates, and the other end of the third spring is fixedly connected to the inner wall of one side of the frame. A hollow coating tube is fixedly connected inside the third spring, and multiple air outlets are provided on the side of the hollow coating tube away from the third spring. Under the action of the third spring, the two hollow coating tubes squeeze the mesh cloth, further scraping off the epoxy resin remaining on the mesh cloth. The two hollow coating tubes can evenly spread the epoxy resin on the mesh cloth. The hot air inside the hollow coating tubes blows obliquely upward through the air outlets, initially solidifying the epoxy resin on the mesh cloth, thus avoiding uneven impregnation of the mesh cloth surface due to the flow of epoxy resin during later transportation.

[0035] In this invention, a rotating shaft passes through the exhaust pipe, and a turbine is fixedly sleeved on the outer wall of the rotating shaft. An S-pole magnet and an N-pole magnet are fixedly connected to the sides of the two connecting blocks that are close to each other. A fixing ring is fixedly sleeved on the outer wall of the rotating shaft, and a magnetic induction line cutting coil is fixedly connected to one side of the fixing ring. A blower blows air heated by a heating element onto the mesh cloth. The hot air enters the exhaust pipe through the mesh within the mesh cloth. The hot air can quickly drive the rotating shaft to rotate. The magnetic induction line cutting coil cuts the magnetic induction lines between the S-pole magnet and the N-pole magnet, energizing the electromagnet. The strength of the electromagnet's magnetic force is then used to detect the presence of a film in the mesh cloth.

[0036] In this invention, an arc-shaped plate is fixedly connected to the bottom of the hollow coating tube, and a rotating rod is rotatably connected inside the arc-shaped plate. An impregnation wheel is fixedly sleeved on the outer wall of the rotating rod. When the two hollow coating tubes work together to evenly coat the epoxy resin in the mesh cloth, excess epoxy resin scraped off the hollow coating tube falls onto the arc-shaped plate along the outer wall of the hollow coating tube, driving the two impregnation wheels to rotate in opposite directions. The impregnation wheels evenly coat the epoxy resin gathered on the arc-shaped plate onto the mesh cloth, further ensuring the uniformity of epoxy resin coating on the mesh cloth.

[0037] In this invention, the epoxy resin on the surface of the mesh fabric is initially scraped off by a rotating scraper, which facilitates the subsequent breaking of the adhesive film in the mesh fabric by the pusher plate. When the pusher plate rotates, it can also drive the U-shaped frame to move up and down, so that the epoxy resin can fully impregnate the mesh fabric. In addition, the flatness of the mesh fabric can be ensured by the cooperation of two hollow coating tubes. The rotation speed of the rotating shaft driven by hot air can detect the presence of adhesive film in the mesh fabric, preventing the mesh fabric carrying adhesive film from being wound up by the take-up roller.

[0058] Reference Figures 1-11This embodiment of an epoxy mesh fabric production impregnation equipment includes a frame 1. A first conveying roller 3, a second conveying roller 5, a third conveying roller 6, a first coating roller 7, a second coating roller 8, and a take-up roller 9 are rotatably connected within the frame 1. An impregnation tank 2 is located below the second and third conveying rollers 5 and 6 within the frame 1. A base plate box 27 and a heating box 28 are bolted together within the frame 1. The base plate box 27 is located below the heating box 28. Multiple blowers 29 are located on the top of the heating box 28. Multiple heating elements 30 are bolted to the inner walls of the opposite sides of the heating box 28. An impregnation structure, located within the impregnation tank 2, is used to ensure that the epoxy resin fully impregnates the mesh fabric. A cleaning structure, located within the frame 1, is used to remove the adhesive film contained within the mesh fabric. A homogenizing structure, located within the frame 1, is used to evenly coat the epoxy resin on the surface of the mesh fabric. A detection structure, located at the bottom of the base plate box 27, is used to detect whether the adhesive film contained within the mesh fabric has been removed to the required standard.

[0059] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 The impregnation structure includes two impregnation rollers 4 rotatably connected inside the impregnation tank 2. A U-shaped frame 10 is slidably connected inside the impregnation tank 2 between the two impregnation rollers 4. A rotating roller 11 for stretching the mesh fabric is rotatably connected inside the U-shaped frame 10. Multiple first springs 12 are fixedly connected to both sides of the top of the impregnation tank 2. The top ends of the multiple first springs 12 on the same side are fixedly connected to the U-shaped frame 10. Connecting plates 13 are fixedly connected to both sides of the top of the U-shaped frame 10 by bolts. When the mesh fabric enters the impregnation tank 2, the rotating shaft 17 drives the cam 19 to rotate. The cam 19 pushes the U-shaped frame 10 to move up and down reciprocally through the connecting plate 13. The rotating roller 11 can drive the mesh fabric between the two impregnation rollers 4 to move up and down, which plays a certain pulling role on the mesh fabric, so that the epoxy resin can fully impregnate the mesh fabric and ensure the impregnation effect of the epoxy resin.

[0060] Reference Figure 3 , Figure 4 and Figure 5The cleaning structure includes a rotating shaft 17 rotatably connected within the frame 1, with the shaft 17 positioned above the connecting plate 13. Multiple pusher plates 18 for vibrating the mesh fabric are fixedly sleeved on the outer wall of the rotating shaft 17. Two cams 19 are fixedly sleeved on the outer wall of the rotating shaft 17, located on either side of the pusher plates 18. The cams 19 cooperate with the connecting plate 13. A rotating scraper 14 is rotatably connected within the impregnation tank 2, cooperating with the second conveying roller 5. When the second conveying roller 5 conveys the impregnated mesh fabric, one side of the rotating scraper 14 initially scrapes away the epoxy resin contained in the mesh fabric on the surface of the second conveying roller 5, preventing excessive epoxy resin from affecting the subsequent removal of the adhesive film in the mesh. The rotating shaft 17 drives the pusher plates 18 to rotate, causing the mesh fabric to vibrate up and down, breaking the residual adhesive film in the mesh holes.

[0061] Reference Figure 3 , Figure 7 and Figure 8 The uniform structure includes two U-shaped slide plates 23 slidably connected within the frame 1. Multiple third springs 24 are fixedly connected to the opposite sides of each U-shaped slide plate 23, and the other end of each third spring 24 is fixedly connected to the inner wall of one side of the frame 1. A hollow coating tube 25 for extruding the mesh fabric is fixedly connected to the third spring 24 by bolts. Multiple air outlets 26 are provided on the side of the hollow coating tube 25 away from the third spring 24 for blowing hot air through the mesh fabric first. The mesh fabric passes through the first coating roller 7 and the second coating roller... When roller 8 is in operation, the two hollow coating tubes 25 are pressed tightly against the mesh fabric by the third spring 24, further scraping off the residual epoxy resin on the mesh fabric. The two hollow coating tubes 25 can also evenly spread the epoxy resin on the mesh fabric. The hot air blown out by the blower 29 enters the hollow coating tubes 25 through the exhaust pipe 31. The hot air is blown obliquely upward through the air outlet 26, which initially solidifies the epoxy resin on the mesh fabric, avoiding uneven impregnation of the mesh fabric surface due to the flow of epoxy resin during the later transportation process.

[0062] Reference Figure 3 , Figure 9 , Figure 10 and Figure 11The detection structure includes two exhaust pipes 31 fixedly connected to the bottom of the base box 27, with the other ends of the two exhaust pipes 31 respectively connected to corresponding hollow coating pipes 25. Multiple pads 45 for supporting the mesh fabric are fixedly connected inside the base box 27 by bolts. A rotating shaft 32 rotatably passes through the exhaust pipes 31. A turbine 33 located inside the exhaust pipes 31 is fixedly sleeved on the outer wall of the rotating shaft 32. Two connecting blocks 34 are fixedly connected to one side of the exhaust pipes 31 by bolts, and the connecting blocks 34 are located on both sides of the rotating shaft 32. An S-pole magnet 35 and an N-pole magnet 36 are respectively fixedly connected to the sides of the two connecting blocks 34 that are close to each other by bolts. The rotating shaft 32... The outer wall is fixedly fitted with a fixing ring 37, and a magnetic induction line cutting coil 38 for cutting the magnetic induction lines between the S pole magnet 35 and the N pole magnet 36 is fixedly connected to one side of the fixing ring 37. When the mesh cloth enters between the bottom plate box 27 and the heating box 28, the blower 29 blows the air heated by the heating plate 30 toward the mesh cloth to dry it. The hot air enters the exhaust pipe 31 through the mesh inside the mesh cloth. The hot air can quickly drive the rotating shaft 32 to rotate. The magnetic induction line cutting coil 38 cuts the magnetic induction lines between the S pole magnet 35 and the N pole magnet 36, energizing the electromagnet 40. Then, the strength of the magnetic force of the electromagnet 40 is used to detect the presence of the adhesive film in the mesh cloth.

[0063] Reference Figure 3 , Figure 9 , Figure 10 and Figure 11 The detection structure also includes a third magnet 39 bolted to one side of the top of the frame 1. An electromagnet 40 is slidably connected to one side of the top of the frame 1. A tension spring 41 is fixedly connected between the electromagnet 40 and the third magnet 39. A first metal contact 42 and a second metal contact 43 are bolted to the electromagnet 40 and the third magnet 39, respectively. An alarm light 44 is bolted to one side of the top of the frame 1, and the first metal contact 42 and the second metal contact 43 are electrically connected to the alarm light 44. A closed circuit is formed between the electromagnet 40 and the magnetic line cutting coil 38. The magnetic line cutting coil 38 cuts the magnetic induction between the S pole magnet 35 and the N pole magnet 36. When the current of the electromagnet 40 is strong, the repulsive force between the electromagnet 40 and the third magnet 39 is greater than the tension of the spring 41. The first metal contact 42 and the second metal contact 43 disengage. When there is still adhesive film in the mesh of the mesh cloth, less hot air enters the exhaust pipe 31. The rotation speed of the rotating shaft 32 slows down, the cutting speed of the magnetic induction line cutting coil 38 decreases, the current in the electromagnet 40 decreases, and the repulsive force between the electromagnet 40 and the third magnet 39 is less than the tension of the spring 41. The first metal contact 42 and the second metal contact 43 touch, and the alarm light 44 is powered on, which facilitates maintenance by the staff and prevents the mesh cloth carrying adhesive film in the mesh from being wound up by the winding roller 9.

A plurality of first magnets 15 are fixedly embedded on the side of the rotating scraper 14 near the second magnets 16 by bolts. When the second conveying roller 5 conveys the impregnated mesh cloth, the epoxy resin contained in the mesh cloth on the surface of the second conveying roller 5 is initially scraped off by the magnetic repulsion between the first magnets 15 and the second magnets 16. Example 2

[0066] Reference Figures 1-13 This embodiment of an epoxy mesh fabric production impregnation equipment includes a frame 1. A first conveying roller 3, a second conveying roller 5, a third conveying roller 6, a first coating roller 7, a second coating roller 8, and a take-up roller 9 are rotatably connected within the frame 1. An impregnation tank 2 is located below the second and third conveying rollers 5 and 6 within the frame 1. A base plate box 27 and a heating box 28 are bolted together within the frame 1. The base plate box 27 is located below the heating box 28. Multiple blowers 29 are located on the top of the heating box 28. Multiple heating elements 30 are bolted to the inner walls of the opposite sides of the heating box 28. An impregnation structure, located within the impregnation tank 2, is used to ensure that the epoxy resin fully impregnates the mesh fabric. A cleaning structure, located within the frame 1, is used to remove the adhesive film contained within the mesh fabric. A homogenizing structure, located within the frame 1, is used to evenly coat the epoxy resin on the surface of the mesh fabric. A detection structure, located at the bottom of the base plate box 27, is used to detect whether the adhesive film contained within the mesh fabric has been removed to the required standard.

[0067] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5The impregnation structure includes two impregnation rollers 4 rotatably connected inside the impregnation tank 2. A U-shaped frame 10 is slidably connected inside the impregnation tank 2 between the two impregnation rollers 4. A rotating roller 11 for stretching the mesh fabric is rotatably connected inside the U-shaped frame 10. Multiple first springs 12 are fixedly connected to both sides of the top of the impregnation tank 2. The top ends of the multiple first springs 12 on the same side are fixedly connected to the U-shaped frame 10. Connecting plates 13 are fixedly connected to both sides of the top of the U-shaped frame 10 by bolts. When the mesh fabric enters the impregnation tank 2, the rotating shaft 17 drives the cam 19 to rotate. The cam 19 pushes the U-shaped frame 10 to move up and down reciprocally through the connecting plate 13. The rotating roller 11 can drive the mesh fabric between the two impregnation rollers 4 to move up and down, which plays a certain pulling role on the mesh fabric, so that the epoxy resin can fully impregnate the mesh fabric and ensure the impregnation effect of the epoxy resin.

[0068] Reference Figure 3 , Figure 4 and Figure 5 The cleaning structure includes a rotating shaft 17 rotatably connected within the frame 1, with the shaft 17 positioned above the connecting plate 13. Multiple pusher plates 18 for vibrating the mesh fabric are fixedly sleeved on the outer wall of the rotating shaft 17. Two cams 19 are fixedly sleeved on the outer wall of the rotating shaft 17, located on either side of the pusher plates 18. The cams 19 cooperate with the connecting plate 13. A rotating scraper 14 is rotatably connected within the impregnation tank 2, cooperating with the second conveying roller 5. When the second conveying roller 5 conveys the impregnated mesh fabric, one side of the rotating scraper 14 initially scrapes away the epoxy resin contained in the mesh fabric on the surface of the second conveying roller 5, preventing excessive epoxy resin from affecting the subsequent removal of the adhesive film in the mesh. The rotating shaft 17 drives the pusher plates 18 to rotate, causing the mesh fabric to vibrate up and down, breaking the residual adhesive film in the mesh holes.

[0069] Reference Figure 3 , Figure 7 and Figure 8The uniform structure includes two U-shaped slide plates 23 slidably connected within the frame 1. Multiple third springs 24 are fixedly connected to the opposite sides of each U-shaped slide plate 23, and the other end of each third spring 24 is fixedly connected to the inner wall of one side of the frame 1. A hollow coating tube 25 for extruding the mesh fabric is fixedly connected to the third spring 24 by bolts. Multiple air outlets 26 are provided on the side of the hollow coating tube 25 away from the third spring 24 for blowing hot air through the mesh fabric first. The mesh fabric passes through the first coating roller 7 and the second coating roller... When roller 8 is in operation, the two hollow coating tubes 25 are pressed tightly against the mesh fabric by the third spring 24, further scraping off the residual epoxy resin on the mesh fabric. The two hollow coating tubes 25 can also evenly spread the epoxy resin on the mesh fabric. The hot air blown out by the blower 29 enters the hollow coating tubes 25 through the exhaust pipe 31. The hot air is blown obliquely upward through the air outlet 26, which initially solidifies the epoxy resin on the mesh fabric, avoiding uneven impregnation of the mesh fabric surface due to the flow of epoxy resin during the later transportation process.

[0070] Reference Figure 3 , Figure 9 , Figure 10 and Figure 11 The detection structure includes two exhaust pipes 31 fixedly connected to the bottom of the base box 27, with the other ends of the two exhaust pipes 31 respectively connected to corresponding hollow coating pipes 25. Multiple pads 45 for supporting the mesh fabric are fixedly connected inside the base box 27 by bolts. A rotating shaft 32 rotatably passes through the exhaust pipes 31. A turbine 33 located inside the exhaust pipes 31 is fixedly sleeved on the outer wall of the rotating shaft 32. Two connecting blocks 34 are fixedly connected to one side of the exhaust pipes 31 by bolts, and the connecting blocks 34 are located on both sides of the rotating shaft 32. An S-pole magnet 35 and an N-pole magnet 36 are respectively fixedly connected to the sides of the two connecting blocks 34 that are close to each other by bolts. The rotating shaft 32... The outer wall is fixedly fitted with a fixing ring 37, and a magnetic induction line cutting coil 38 for cutting the magnetic induction lines between the S pole magnet 35 and the N pole magnet 36 is fixedly connected to one side of the fixing ring 37. When the mesh cloth enters between the bottom plate box 27 and the heating box 28, the blower 29 blows the air heated by the heating plate 30 toward the mesh cloth to dry it. The hot air enters the exhaust pipe 31 through the mesh inside the mesh cloth. The hot air can quickly drive the rotating shaft 32 to rotate. The magnetic induction line cutting coil 38 cuts the magnetic induction lines between the S pole magnet 35 and the N pole magnet 36, energizing the electromagnet 40. Then, the strength of the magnetic force of the electromagnet 40 is used to detect the presence of the adhesive film in the mesh cloth.

[0071] Reference Figure 3 , Figure 9 , Figure 10 and Figure 11The detection structure also includes a third magnet 39 bolted to one side of the top of the frame 1. An electromagnet 40 is slidably connected to one side of the top of the frame 1. A tension spring 41 is fixedly connected between the electromagnet 40 and the third magnet 39. A first metal contact 42 and a second metal contact 43 are bolted to the electromagnet 40 and the third magnet 39, respectively. An alarm light 44 is bolted to one side of the top of the frame 1, and the first metal contact 42 and the second metal contact 43 are electrically connected to the alarm light 44. A closed circuit is formed between the electromagnet 40 and the magnetic line cutting coil 38. The magnetic line cutting coil 38 cuts the magnetic induction between the S pole magnet 35 and the N pole magnet 36. When the current of the electromagnet 40 is strong, the repulsive force between the electromagnet 40 and the third magnet 39 is greater than the tension of the spring 41. The first metal contact 42 and the second metal contact 43 disengage. When there is still adhesive film in the mesh of the mesh cloth, less hot air enters the exhaust pipe 31. The rotation speed of the rotating shaft 32 slows down, the cutting speed of the magnetic induction line cutting coil 38 decreases, the current in the electromagnet 40 decreases, and the repulsive force between the electromagnet 40 and the third magnet 39 is less than the tension of the spring 41. The first metal contact 42 and the second metal contact 43 touch, and the alarm light 44 is powered on, which facilitates maintenance by the staff and prevents the mesh cloth carrying adhesive film in the mesh from being wound up by the winding roller 9.

[0072] Reference Figure 3 and Figure 6 A fixed horizontal plate 20 is bolted to the frame 1. Multiple second springs 21 are fixedly connected to the side of the fixed horizontal plate 20 near the third conveying roller 6. The other end of the multiple second springs 21 is fixedly connected to the same arc-shaped scraper 22, and the arc-shaped scraper 22 is slidably connected in the frame 1. The arc-shaped scraper 22 cooperates with the third conveying roller 6. The adhesive film remaining in the mesh holes is broken by vibration, and the broken adhesive film still remains on the surface of the mesh cloth. Under the elastic force of the second springs 21, the arc-shaped scraper 22 is tightly pressed against the third conveying roller 6, and the arc-shaped scraper 22 can scrape off the adhesive film on the surface of the mesh cloth again.

[0073] Reference Figure 3 and Figure 4 A plurality of second magnets 16 are fixedly connected to one side of the inner wall of the impregnation tank 2 by bolts. A plurality of first magnets 15 are fixedly embedded on the side of the rotating scraper 14 near the second magnets 16 by bolts. When the second conveying roller 5 conveys the impregnated mesh cloth, the epoxy resin contained in the mesh cloth on the surface of the second conveying roller 5 is initially scraped off by the magnetic repulsion between the first magnets 15 and the second magnets 16.

[0074] Reference Figure 12 and Figure 13The bottom of the hollow coating tube 25 is fixedly connected to an arc-shaped plate 46 by bolts. A rotating rod 47 is rotatably connected inside the arc-shaped plate 46. An impregnation wheel 48 is fixedly sleeved on the outer wall of the rotating rod 47. A baffle 49 is fixedly connected to the top of the arc-shaped plate 46 by bolts, and the baffle 49 contacts the outer wall of the impregnation wheel 48. When the two hollow coating tubes 25 work together to evenly coat the epoxy resin in the mesh cloth, the excess epoxy resin scraped off the hollow coating tubes 25 falls onto the arc-shaped plate 46 along the outer wall of the hollow coating tubes 25. At this time, the two impregnation wheels 48 are driven by a motor to rotate in opposite directions. The impregnation wheels 48 evenly coat the epoxy resin accumulated on the arc-shaped plate 46 onto the mesh cloth, further ensuring the uniformity of epoxy resin coating on the mesh cloth.

[0075] A method for using an impregnation device for producing epoxy mesh fabric includes the following steps:

[0076] S1. The winding roller 9 is driven by a motor to rotate, and the winding roller 9 winds up the mesh fabric to the right. When the mesh fabric enters the impregnation box 2, the rotating shaft 17 is driven by a motor to rotate. The rotating shaft 17 drives the cam 19 to rotate. The cam 19 pushes the U-shaped frame 10 to move up and down reciprocally through the connecting plate 13. The rotating roller 11 can drive the mesh fabric between the two impregnation rollers 4 to move up and down, which plays a certain pulling role on the mesh fabric, so that the epoxy resin can fully impregnate the mesh fabric and ensure the impregnation effect of the epoxy resin.

[0077] S2. When the second conveying roller 5 conveys the impregnated mesh cloth, the magnetic repulsion between the first magnet 15 and the second magnet 16 is used to rotate one side of the scraper 14 to initially scrape off the epoxy resin contained in the mesh cloth on the surface of the second conveying roller 5, so as to avoid the excessive epoxy resin in the mesh cloth from affecting the removal of the adhesive film in the mesh later.

[0078] S3. When the mesh cloth enters below the rotating shaft 17, the rotating shaft 17 drives the pusher plate 18 to rotate. The pusher plate 18 can drive the mesh cloth to vibrate up and down, which is used to break the adhesive film remaining in the mesh holes. The broken adhesive film still remains on the surface of the mesh cloth. Under the elastic force of the second spring 21, the arc-shaped scraper 22 is tightly attached to the third conveying roller 6. The arc-shaped scraper 22 can scrape off the adhesive film on the surface of the mesh cloth again.

[0079] S4. When the mesh fabric passes through the first coating roller 7 and the second coating roller 8, the two hollow coating tubes 25 are pressed tightly against the mesh fabric by the action of the third spring 24, further scraping off the residual epoxy resin on the mesh fabric. The two hollow coating tubes 25 can evenly scrape the epoxy resin on the mesh fabric. The hot air blown out by the blower 29 enters the hollow coating tube 25 through the exhaust pipe 31. The hot air is blown obliquely upward through the air outlet 26, which initially solidifies the epoxy resin on the mesh fabric, avoiding uneven impregnation of the mesh fabric surface due to the flow of epoxy resin during the later transportation process.

[0080] S5. When the mesh cloth enters between the base plate box 27 and the heating box 28, the blower 29 blows the air heated by the heating element 30 onto the mesh cloth to dry it. The hot air enters the exhaust pipe 31 through the mesh inside the mesh cloth. The hot air can quickly drive the rotating shaft 32 to rotate. The magnetic induction line cutting coil 38 cuts the magnetic induction lines between the S pole magnet 35 and the N pole magnet 36. The current of the electromagnet 40 is strong. The repulsive force generated between the electromagnet 40 and the third magnet 39 is greater than the tension of the tension spring 41. The first metal contact 42 and the second When the metal contact 43 disengages from contact, and when the adhesive film remains in the mesh of the mesh cloth, the hot air entering the exhaust pipe 31 has a smaller force, the rotation speed of the rotating shaft 32 slows down, the cutting speed of the magnetic induction line cutting coil 38 decreases, the current in the electromagnet 40 decreases, and the repulsive force between the electromagnet 40 and the third magnet 39 is less than the tension of the tension spring 41. The first metal contact 42 and the second metal contact 43 come into contact, and the alarm light 44 is powered on, which facilitates maintenance by the staff and prevents the mesh cloth carrying the adhesive film in the mesh from being wound up by the winding roller 9.

[0081] S6. When the two hollow coating tubes 25 work together to evenly coat the epoxy resin in the mesh cloth, the excess epoxy resin scraped off the hollow coating tubes 25 falls onto the arc plate 46 along the outer wall of the hollow coating tubes 25. At this time, the two impregnation wheels 48 are driven by the motor to rotate in opposite directions. The impregnation wheels 48 evenly coat the epoxy resin gathered on the arc plate 46 onto the mesh cloth, further ensuring the uniformity of epoxy resin coating on the mesh cloth.

[0082] However, as is well known to those skilled in the art, the working principles and wiring methods of the electromagnet 40, the first metal contact 42, the second metal contact 43, the magnetic wire cutting coil 38, the heating element 30, the blower 29, and the alarm light 44 are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
