Description

Technical Field

[0001] This invention relates to the field of adhesive impregnation mechanism technology, specifically to an adhesive impregnation mechanism and its impregnation process for a high-temperature tape production line. Background Technology

[0002] The adhesive tape production process involves controlling the conveying of the tape body into the adhesive solution, allowing it to be fully wetted and absorb the adhesive. After a film forms on the surface of the tape body, it is removed from the adhesive solution, and then the film is cured.

[0003] In existing adhesive impregnation technology, the material belt is immersed in adhesive, and the adhesive components are naturally adsorbed, gradually forming an adhesive layer on the surface of the material belt. However, the adhesive layer formed in this way has a low internal density, resulting in insufficient adhesive film formation. The produced tape has low viscosity, and the adhesive layer is not tightly bonded to the fabric fibers on the belt surface, causing the adhesive film to easily detach during subsequent processing or use, reducing the product's peel resistance. When the low-density adhesive film is transported vertically with the material belt, it may experience sagging due to gravity, leading to uneven coating and affecting the product's flatness. Low-density adhesive films are prone to deformation in high or low temperature environments; for example, in automotive window tinting, it may cause bubbles or cracks, shortening the product's lifespan.

[0004] Improving the density of the formed adhesive layer is a key area of ​​technological research and development. While parameters such as the movement speed, temperature, and time of the adhesive components can be adjusted, the effect is not significant. Applying external pressure to the formed adhesive layer can cause the internal components to gradually become denser, thereby directly increasing the component density. To address this, the present invention provides an adhesive dipping mechanism and its dipping process for a high-temperature tape production line. Summary of the Invention

[0005] The purpose of this invention is to provide a dipping mechanism and dipping process for a high-temperature tape production line, so as to solve the problem of low density of adhesive layer components mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a glue-dipping mechanism for a high-temperature tape production line, comprising:

[0007] The dipping frame and the dipping tank hinged to the dipping frame at one end, the dipping tank being a long tank shell shape, and the other end of the dipping tank being suspended by a chain, a soft material belt being conveyed above the dipping tank, and glue being stored in the dipping tank for the soft material belt to pass through for dipping.

[0008] Two shaft rollers distributed in the impregnation tank are used to guide the material conveyor belt to change direction, and a T-shaped wall plate is fixed on the impregnation frame. The T-shaped wall plate is provided with a bracket to support the shaft rollers.

[0009] The inner cross frame is distributed below the material soft strip, the rope adjuster is supported at both ends of the inner cross frame, and multiple circulating conveying scraping ropes are connected between the two rope adjusters. One end of the inner cross frame is fixed to the T-shaped wall panel. The bottom horizontal belt surface of the material soft strip is adhered with an adhesive layer. The horizontal cylindrical section of the scraping rope moves and scrapes the adhesive layer under the adhesive layer to increase the adhesion density of the adhesive.

[0010] The inner crossbeam also supports a long drive shaft and an elastic paddle fixed below the middle of the inner crossbeam. The long drive shaft drives the rope adjuster to transport the scraping rope, and the elastic paddle moves the scraping rope it encounters to remove the attached material.

[0011] The rope adjuster includes:

[0012] A flat, closed-loop chain, and sprockets distributed at both ends inside the chain, with the long drive shaft passing through the middle of the sprockets;

[0013] Multiple rope adjustment units are supported on one side of the chain. The ends of the scraping rope are connected to the rope adjustment units, and the rope adjustment units at both ends of the scraping rope are synchronously conveyed to make the scraping rope move horizontally.

[0014] The rope adjuster also includes a stepped plate and a J-shaped crossbar that respectively press the rope adjusting unit. The inner crossbar is equipped with an adjusting frame to position and support the stepped plate and the J-shaped crossbar.

[0015] The stepped plate has a stepped surface pressure adjustment unit on one side so that the row of scraping ropes used for pushing and scraping are distributed in a stepped layer. At the same time, the J-shaped horizontal column pressure adjustment unit makes the scraping ropes used for pushing and scraping taut.

[0016] The adjusting rope unit includes a frame column with one end fixed to a chain, a T-shaped sliding plate that slides on the other end of the frame column, an L-shaped rack fixed to one side of the T-shaped sliding plate, and a pressing assembly for driving the L-shaped rack. An L-shaped guide post is provided on the frame column to slide through a square hole opened in the middle of the T-shaped sliding plate.

[0017] The rope adjusting unit also includes L-shaped directional bars distributed on both sides of the T-shaped sliding plate, and springs sleeved on the L-shaped directional bars. The L-shaped directional bars slide through the round holes opened on the T-shaped sliding plate, and the springs are placed between the interception seats set at the ends of the T-shaped sliding plate and the L-shaped directional bars.

[0018] The springs at both ends of the scraper rope apply pressure to provide tension to the scraper rope, and the tension of the scraper rope is changed by controlling the displacement of the T-shaped sliding plate.

[0019] The rope adjusting unit also includes a rope head assembly connected between two L-shaped directional bars, and the rope head assembly is connected to the scraping rope;

[0020] The stepped plate presses the rope end assembly to control the distance between the scraping rope and the soft material strip, and each stepped surface on the stepped plate is in contact with a corresponding rope end assembly below.

[0021] The press assembly includes an inlet shaft and an actuating gear mounted on a frame column, and a lever plate fixed at one end of the inlet shaft. The other end of the inlet shaft is perpendicular to the actuating gear, and the J-shaped crossbar contacts and presses the lever plate that passes through it.

[0022] The driving gear and L-shaped rack mesh for transmission. The driving gear passes through the shaft in the middle, and the shaft end on the driving gear meshes with the bevel gear fixed at the end of the guide shaft through a fixed bevel gear.

[0023] The rope end assembly includes an L-shaped limiting seat fixed between two L-shaped directional bars, a T-shaped spacing frame that slides through a square hole in the L-shaped limiting seat at one end, a rope end rigid plate fixed on the T-shaped spacing frame, a roller supported on the T-shaped spacing frame, and a C-shaped spring for pushing the T-shaped spacing frame. The roller is pressed by a stepped plate it encounters.

[0024] One end of the C-shaped spring is fixed on the L-shaped limiting seat, the end of the scraping rope and the rope head hard plate are fixedly connected, and the middle part of the roller is movably sleeved in the through hole opened on the T-shaped spacing frame by setting a shaft.

[0025] A high-temperature tape production line dip-coating process includes the following steps:

[0026] Step 1: Pour the prepared glue into the impregnation tank and heat the glue to the specified impregnation temperature using a heating mechanism;

[0027] Step 2: The material belt is conveyed into the impregnation tank. Under the immersion of glue in the impregnation tank, a glue film is gradually formed on the surface of the material belt.

[0028] Step 3: The thickness of the adhesive film on the material belt gradually increases. During the process, the lower surface of the adhesive film is pushed and pressed one by one by the scraper ropes that are being conveyed, and the density of the adhesive film increases under multiple external pressures.

[0029] Step 4: The material strip with the film formed on the surface is conveyed away from the dip tank. One end of the dip tank is lowered to tilt itself, thereby pouring out the consumed glue. New glue will be added for the next dip operation.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. Compared with the problems of low adhesive density and low adhesion of the adhesive layer generated by traditional dipping technology, the present invention uses a row of scraping ropes to push and scrape the gradually growing adhesive layer surface in turn. In this way, the internal components of the adhesive layer become denser by applying external pressure multiple times, resulting in a high internal density of the adhesive layer and producing tape with sufficient viscosity and stability.

[0032] 2. During the process of scraping the adhesive layer with a scraper rope, the scraper rope is kept taut, which allows it to stably scrape the lower surface of the adhesive layer. A row of scraper ropes is distributed in a stepped manner to adapt to the gradual increase in the thickness of the adhesive layer. After the scraping is completed, the scraper rope automatically loosens and is then pushed by the elastic paddle. The loosened scraper rope vibrates, causing the adhesive residue attached to the scraper rope to fall off. The cleaned scraper rope then begins the next round of scraping.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the technical solutions of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Please see Figures 1 to 15 This invention provides a technical solution: a dipping mechanism for a high-temperature tape production line, comprising:

[0051] The impregnation frame 1 and the impregnation tank 2, which is hinged to the impregnation frame 1 at one end, are long tank shells and the other end of the impregnation tank 2 is suspended by a chain. A soft material belt 5 is conveyed above the impregnation tank 2 and the impregnation tank 2 stores glue for the soft material belt 5 to pass through for impregnation.

[0052] Two rollers 4 distributed in the impregnation tank 2 are used to guide the material conveyor belt 5 to change direction, and a T-shaped wall plate 3 is fixed on the impregnation frame 1. A bracket is provided on the T-shaped wall plate 3 to support the rollers 4. A rotating shaft is fixed at the end of the rollers 4, and the rotating shaft is movably sleeved in the through hole opened on the bracket.

[0053] The inner cross frame 6 is distributed below the material soft belt 5, the rope adjuster 7 is supported at both ends of the inner cross frame 6, and the two rope adjusters 7 are connected to the multiple circulating conveying scraper ropes 8. One end of the inner cross frame 6 is fixed on the T-shaped wall panel 3. The bottom horizontal belt surface of the material soft belt 5 is adhered with an adhesive layer. The horizontal cylindrical section of the scraper rope 8 moves and scrapes the adhesive layer under the adhesive layer to increase the adhesion density of the adhesive.

[0054] The inner cross frame 6 also supports a long drive shaft 9 and an elastic lever 10 fixed in the lower middle part of the inner cross frame 6. The long drive shaft 9 drives the rope adjuster 7 to transport the scraping rope 8, and the elastic lever 10 moves the scraping rope 8 encountered to remove the attached object. The two ends of the long drive shaft 9 are respectively movably sleeved in two through holes opened on the inner cross frame 6. The two long drive shafts 9 are distributed in parallel on both sides of the inner cross frame 6. The transport path of the scraping rope 8 is a flat closed loop path. Multiple scraping ropes 8 are evenly distributed on the transport path. The upper row of scraping ropes 8 is used for pushing and scraping, and the lower row of scraping ropes 8 is scraped one by one by the elastic lever 10 encountered after being loosened.

[0055] To understand this in detail, the scraper rope 8 is a slender cylinder. The upper half of the horizontal cylindrical surface of the scraper rope 8 is an upward-convex arc surface. This convex arc surface contacts and pushes the lower surface of the adhesive layer. Under the pushing force, the adhesive component on the lower surface rises to a certain extent and fuses more tightly with the adhesive component above. In this way, the external pressure increases the density of the adhesive component, and the adhesive layer adheres more firmly to the material strip 5. The adhesive in the adhesive layer can be understood as a denser slurry compared to the adhesive flowing in the dip tank 2. When the scraper rope 8 pushes the lower surface of the adhesive layer, some slurry will also adhere to the scraper rope 8. Therefore, after the scraper rope 8 completes a single push of the adhesive layer, it needs to pass through a spring rope. That is, as mentioned earlier, the scraper rope 8 is pushed when it encounters the elastic lever 10. This causes the scraper rope 8 to vibrate rapidly, causing the slurry adhering to its surface to fall off.

[0056] Reference Appendix Figure 8 and attached Figure 9 Understandably, the rope adjuster 7 includes: a flat closed-loop chain 13, and sprockets 11 distributed at both ends inside the chain 13. A long drive shaft 9 passes through the middle of the sprockets 11. The long drive shaft 9 is externally connected to a drive mechanism in the prior art. The long drive shaft 9 drives the sprockets 11 to rotate, thereby driving the chain 13 to convey. Under the drive of the long drive shaft 9, the chains 13 at both ends are conveyed synchronously.

[0057] Multiple rope adjustment units 12 are supported on one side of the chain 13. The ends of the scraper rope 8 are connected to the rope adjustment units 12, and the rope adjustment units 12 at both ends of the scraper rope 8 are synchronously conveyed to make the scraper rope 8 translate.

[0058] Reference Appendix Figure 8The rope adjuster 7 also includes a stepped plate 14 and a J-shaped crossbar 15 that respectively press the rope adjusting unit 12. The stepped plate 14 and the J-shaped crossbar 15 are positioned and supported by an adjusting frame 16 on the inner crossbar 6. Both the stepped plate 14 and the J-shaped crossbar 15 are provided with vertical protrusions. The vertical protrusions on the stepped plate 14 pass through the inner hole of the first flat cylinder fixed on the adjusting frame 16 and are bolted to one side of the first flat cylinder. The bolts press against the vertical protrusions of the stepped plate 14 to achieve spatial positioning of the stepped plate 14. The vertical protrusions on the J-shaped crossbar 15 pass through the inner hole of the second flat cylinder fixed on the adjusting frame 16 and are bolted to one side of the second flat cylinder. The bolts press against the vertical protrusions of the J-shaped crossbar 15 to achieve spatial positioning of the J-shaped crossbar 15. The adjusting frame 16 is fixed on the inner crossbar 6.

[0059] The stepped plate 14 has a stepped surface pressure adjustment rope unit 12 on one side, so that the row of scraping ropes 8 used for pushing and scraping are distributed in a stepped layer. At the same time, the J-shaped horizontal column 15 presses the adjustment rope unit 12 so that the scraping ropes 8 used for pushing and scraping are taut.

[0060] Reference Appendix Figure 14 Understandably, the spacing between each scraper rope 8 and the material belt 5 is different, with the spacing being larger towards the left. The scraper rope 8 is slowly conveyed horizontally to the right, and the material belt 5 is slowly conveyed horizontally to the left. After the material belt 5 is immersed in the adhesive, an adhesive layer gradually forms on its surface, which is the adhesive layer or adhesive film mentioned earlier. The initially formed adhesive layer is thin, and it initially comes into contact with the rightmost scraper rope 8, meaning the scraper rope 8 pushes against the lower surface of the adhesive layer. This external pressure acts on the interior of the adhesive layer, causing the density of the internal components to increase. Subsequently, the material belt 5... As the conveying continues, more adhesive adheres to the material belt 5, increasing the thickness of the adhesive layer. If the distance between the scraper rope 8 and the material belt 5 remains unchanged, the lower surface of the adhesive layer will be lower than the scraper rope 8. The shifting scraper rope 8 will directly push away the subsequently adhered adhesive, thus interrupting the growth of the adhesive layer. In order to continue to scrape the lower surface of the adhesive layer with the scraper rope 8, the distance between the scraper rope 8 and the material belt 5 needs to be gradually increased. Therefore, in this invention, a row of scraper ropes 8 is distributed in a stepped manner to smoothly achieve multiple scraping of the adhesive layer, so that the gradual increase in adhesive layer thickness and multiple scraping are achieved in synergy.

[0061] Reference Appendix Figure 12 The adjusting rope unit 12 includes a frame column 17 with one end fixed to the chain 13, a T-shaped sliding plate 21 that slides on the other end of the frame column 17, an L-shaped rack 20 fixed on one side of the T-shaped rack 21, and a pressing assembly 18 for driving the L-shaped rack 20. An L-shaped guide post is provided on the frame column 17 to slide through a square hole opened in the middle of the T-shaped rack 21.

[0062] Reference Appendix Figure 11 and attached Figure 12It is understood that the chain 13 consists of multiple joints, and each joint includes an inner chain plate 131, an outer chain plate 133, and a pin 132 for hinged connection between the inner chain plate 131 and the outer chain plate 133. The outer chain plates 133 on both sides of a single joint are fixedly connected to a support column 17.

[0063] The rope adjustment unit 12 also includes L-shaped directional bars 22 distributed on both sides of the T-shaped sliding plate 21, and springs 19 sleeved on the L-shaped directional bars 22. The L-shaped directional bars 22 slide through the round holes opened on the T-shaped sliding plate 21, and the springs 19 are placed between the interception seats provided at the ends of the T-shaped sliding plate 21 and the L-shaped directional bars 22.

[0064] The springs 19 at both ends of the scraper rope 8 apply pressure to provide tension to the scraper rope 8, and the tension of the scraper rope 8 is changed by controlling the displacement of the T-shaped sliding plate 21.

[0065] The rope adjusting unit 12 also includes a rope end assembly 23 connected between two L-shaped directional bars 22, and the rope end assembly 23 is connected to the scraping rope 8;

[0066] The step plate 14 presses against the rope end assembly 23 to control the spacing between the scraping rope 8 and the material soft strip 5. Each step surface on the step plate 14 is in contact with a corresponding rope end assembly 23.

[0067] The press assembly 18 includes an inlet shaft 25 and an actuating gear 26 mounted on a frame column 17, and a lever plate 24 fixed at one end of the inlet shaft 25. The other end of the inlet shaft 25 is perpendicularly driven to the actuating gear 26. The J-shaped crossbar 15 contacts and presses against the lever plate 24. (See attached diagram) Figure 15 Understanding that the conveying path of the lever pressure plate 24 is a flat closed loop, with the upper row of lever pressure plates 24 all being pressed by J-shaped horizontal columns 15, the lever pressure plate 24 swinging to drive the guide shaft 25 to rotate, which in turn drives the gear 26 to rotate, causing the L-shaped rack 20 to translate, thereby causing the attached... Figure 12 The T-shaped sliding plate 21 moves to the left, compressing and contracting the spring 19. The spring 19 provides stronger elasticity to the L-shaped directional bar 22, which in turn pulls the scraping rope 8 through the rope head assembly 23. The tension of the scraping rope 8 increases. After the scraping rope 8 completes the scraping of the adhesive film, it is conveyed to the lower position, corresponding to the attached... Figure 15 The lower row of lever pressure plates 24 is no longer compressed at this time, corresponding to the attached... Figure 12When the T-shaped sliding plate 21 is reset, that is, when the T-shaped sliding plate 21 moves to the right to its maximum extent, the spring 19 is stretched to its maximum extent, and the pressure provided by the spring 19 to the scraper rope 8 is minimized, the tension of the scraper rope 8 decreases. In this way, when the scraper rope 8 is triggered by the elastic lever 10, the scraper rope 8 vibrates smoothly, thereby causing the adhesive residue to fall off. If the tension of the scraper rope 8 is not reduced, the highly taut scraper rope 8 will be triggered by the elastic lever 10 once for each closed-loop conveying. Repeated triggering of the highly taut scraper rope 8 may cause the scraper rope 8 to break, or the taut scraper rope 8 may not vibrate. In addition, the spring 19 avoids elastic fatigue by stretching and relaxing.

[0068] The driving gear 26 and the L-shaped rack 20 mesh for transmission. The driving gear 26 has a shaft that passes through the middle, and the shaft end of the driving gear 26 meshes with the bevel gear fixed at the end of the guide shaft 25 through a fixed bevel gear. Two baffles are provided on the support columns 17 on both sides of the driving gear 26. The shaft of the driving gear 26 is movably sleeved in the through hole opened on the baffle. A limiting seat is also provided on the support column 17, and the guide shaft 25 is movably sleeved in the through hole opened on the limiting seat.

[0069] The rope end assembly 23 includes an L-shaped limiting seat 31 fixed between two L-shaped directional bars 22, a T-shaped spacing frame 28 that slides through a square hole in the L-shaped limiting seat 31 at one end, a rope end rigid plate 27 fixed on the T-shaped spacing frame 28, a roller 30 supported on the T-shaped spacing frame 28, and a C-shaped spring 29 for pushing the T-shaped spacing frame 28. The roller 30 is pressed by the step plate 14 it encounters.

[0070] One end of the C-shaped spring clip 29 is fixed to the L-shaped limiting seat 31. The end of the scraping rope 8 is fixedly connected to the rope head rigid plate 27. The middle part of the roller 30 is movably sleeved in the through hole opened on the T-shaped spacing frame 28 by setting a shaft. (See attached figure) Figure 13 When the T-shaped spacing frame 28 rises and falls within the specified range, and the roller 30 does not encounter the step plate 14, the C-shaped spring piece 29 pushes the T-shaped spacing frame 28, and the T-shaped spacing frame 28 drives the rope end plate 27 to rise. An intercepting block is set at the bottom of the T-shaped spacing frame 28 to limit the rising distance of the T-shaped spacing frame 28. After the roller 30 encounters the step plate 14, the roller 30 is compressed and falls, and then the T-shaped spacing frame 28, the rope end plate 27 and the scraping rope 8 fall synchronously, and the C-shaped spring piece 29 is deformed by pressure.

[0071] Reference Appendix Figure 14 The distance between the scraper rope 8 and the material belt 5 depends on the pressure of the step plate 14 on the roller 30. As the scraper rope 8 is conveyed horizontally to the right, the pressure depth of the roller 30 at the end of the scraper rope 8 by the step plate 14 gradually decreases. As the roller 30 is conveyed to the right, it gradually rises, which corresponds to controlling the distance between the scraper rope 8 and the material belt 5 to gradually decrease.

[0072] Analysis and summary of the conveying and stress states of a single scraper rope 8: The conveying path of the scraper rope 8 is a flat closed loop. When the scraper rope 8 is conveyed and moved horizontally above, it pushes and scrapes the lower surface of the adhesive layer on the soft material belt 5 during the horizontal movement. At this time, the scraper rope 8 is in a taut state, and the scraper rope 8 moves in a stepped manner during the horizontal movement. As mentioned before, the stepped upward movement of the scraper rope 8 is due to the pressure control of the stepped surface of the stepped plate 14 during the horizontal movement of the roller 30 at the source. The tautness of the scraper rope 8 is due to the pressure of the corresponding lever plate 24 being pressed by the J-shaped horizontal column 15, which in turn causes the spring 19 to contract. The spring 19 provides a stronger thrust to the L-shaped directional bar 22, and the L-shaped directional bar 22 drives the entire rope head assembly 23, which in turn provides a stronger tension to the scraper rope 8. After the scraper rope 8 moves horizontally to the top, it descends in an arc and then begins to move horizontally downwards. At this time, the scraper rope 8 is in a relaxed state and encounters the elastic lever 10 during the conveying process. The elastic lever 10 will push the relaxed scraper rope 8, and the scraper rope 8 will automatically shake to remove the adhering adhesive. The scraper rope 8, after cleaning, will be put into the next round of scraping operation. The reason for the relaxation of the scraper rope 8 is that the lever pressure plate 24 is no longer pressed by the J-shaped crossbar 15, and the corresponding spring 19 returns to its original position and extends, reducing the pressure provided by the spring 19 to the scraper rope 8.

[0073] A high-temperature tape production line dip-coating process includes the following steps:

[0074] Step 1: Pour the prepared glue into the impregnation tank 2, and heat the glue to the specified impregnation temperature using the heating mechanism;

[0075] Step 2: The material soft belt 5 is conveyed into the glue impregnation tank 2. Under the immersion of glue in the glue impregnation tank 2, a glue film is gradually formed on the surface of the material soft belt 5.

[0076] Step 3: The thickness of the adhesive film on the material soft belt 5 gradually increases. During the process, the lower surface of the adhesive film is pushed and pressed one by one by the scraper rope 8 that is being conveyed. The density of the adhesive film increases under multiple external pressures.

[0077] Step 4: The material strip 5 with the surface film formed is conveyed away from the dip tank 2. One end of the dip tank 2 is lowered to tilt itself, thereby pouring out the consumed glue. New glue will be added for the next dip operation.

[0078] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
