Description

Technical Field

[0001] This invention relates to the field of tire processing technology, specifically to an inner tube coating device for tire processing and its usage method. Background Technology

[0002] Tire manufacturing is the process of transforming various raw materials into tires through a series of complex processes and procedures. A common part of tire manufacturing is the application of adhesive. Adhesive coating serves multiple purposes, such as enhancing the adhesion between tire components, improving overall tire performance and quality, and preventing air leakage. Tire adhesive coating includes both outer tire coating and inner tube coating. Outer tire coating primarily occurs between components such as the ply layers and tread compound. Inner tube coating is also crucial; the adhesive fills the tiny pores in the inner tube material, forming an airtight layer that reduces air leakage through the inner tube wall, thereby maintaining stable tire pressure.

[0003] In existing technologies, during tire manufacturing, inner tubes are typically coated with adhesive using a roller coating method. A rotating roller transfers the adhesive to the flat, strip-shaped surface of the inner tube, achieving a relatively smooth coating effect. When using an inner tube coating device, a steel roller is usually placed next to the coating roller. Adjusting the position of the steel roller adjusts the distance between the steel roller and the coating roller, thus regulating the amount of adhesive applied. However, current steel roller adjustments are generally made manually, adjusting both ends of the steel roller sequentially. This is not only cumbersome but also makes it difficult to ensure the precision and consistency of the adjustments at both ends. This can easily lead to inconsistent distances between the steel roller and the coating roller at both ends, affecting the quality of the inner tube coating.

[0004] Therefore, we propose an inner tube coating device for tire processing to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to provide an inner tube coating device for tire processing, which solves the problem that the inner tube coating device mentioned in the background art requires manual adjustment of the position of the steel rollers at both ends to adjust the amount of adhesive. This is not only cumbersome, but also makes it difficult to ensure the accuracy and consistency of the adjustment at both ends, which can easily lead to inconsistent distances between the steel rollers and the coating rollers at both ends, affecting the quality of inner tube coating.

One end of the other two air ducts is fixedly inserted through the movable frame and the two sealing plates to the interior of the adjusting roller.

[0015] A method of using an inner tube adhesive applicator for tire processing includes the following steps: S1. Start the hydraulic rod to push the moving frame and adjusting roller to move, which in turn moves the annular tube and the outer tube together. At the same time, it pulls the fixed tube to move. With the cooperation of the limiting groove and the limiting ring, it drives the scale ring to move. Under the guidance of the rotating guide bar, the scale ring drives the amplifying rod to rotate upwards. S2. The magnifying lens magnifies the numbers on the scale sticker, the camera captures clear images of the numerical scale, and sends them to the intelligent control system for comparison and analysis. When the numerical scale on the image matches the set data, the hydraulic rod is automatically closed. S3. Start the metering glue pump. The glue is delivered to the area between the glue coating roller and the adjusting roller through the glue supply pipe and the glue discharge pipe. Start the rotation motor and glue coating motor in advance to drive the glue coating roller and the adjusting roller to rotate, so that the glue coating roller is evenly coated with glue on its outer surface. Start the conveying system to convey the inner tube. After passing the bottom of the glue coating roller, the glue on the outer surface of the glue coating roller is evenly coated on the surface of the inner tube. S4. The connecting pipe delivers hot air sequentially to the telescopic pipe and the fixed pipe. It enters the annular pipe through the outer pipe and blows the hot air into the adjusting roller through the air duct. Then, the hot air enters the outlet pipe through the air duct, the annular pipe and the outer pipe and is blown downward.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In use, the flat inner tube is conveyed to the coating roller via a conveying system, where the coating roller applies adhesive to the inner tube surface. Activating the hydraulic rod moves the moving frame and adjusting roller, causing the annular tube and outer tube to move together, while simultaneously pulling the fixed tube. With the cooperation of the limiting groove and limiting ring, the scale ring moves. Guided by the rotating guide bar, the scale ring causes the magnifying rod to rotate upwards, magnifying the numbers on the scale. The camera captures clear images of the scale and sends them to the intelligent control system for comparison and analysis. When the numerical scale in the image matches the set data, the hydraulic rod automatically closes. With the cooperation of the moving adjustment component and the distance monitoring component, intelligent automated distance adjustment is achieved. Furthermore, the magnifying effect of the magnifying lens allows the camera to capture clearer and more prominent numbers, more accurately detecting changes in the moving distance, improving the accuracy and consistency of distance adjustment, and ultimately improving the quality of the inner tube coating.

[0017] 2. In use, the metering glue pump is started, and glue is delivered to the area between the coating roller and the adjusting roller through the glue application pipe and the glue discharge pipe. The rotary motor and the glue application motor are started in advance to drive the coating roller and the adjusting roller to rotate, ensuring that the outer surface of the coating roller is evenly coated with glue. The conveying system is started to transport the inner tube, passing it under the coating roller. The glue on the outer surface of the coating roller is evenly coated onto the surface of the inner tube, thus completing the inner tube coating process. The glue collection frame collects glue dripping from both ends of the adjusting roller and the coating roller, preventing glue from dripping onto the equipment table. Pulling the four corner levers out of the slots and grooves allows the glue collection frame to be pulled outwards, facilitating the collection of recycled glue for reuse.

[0018] 3. In use, the connecting pipe sequentially delivers hot air to the telescopic pipe and the fixed pipe, then enters the annular pipe through the outer connecting pipe. The hot air is then blown into the adjusting roller through the air duct, increasing its temperature, reducing the viscosity of the adhesive, improving its fluidity, and making it easier for the coating roller to adhere the adhesive. This facilitates more even coating of the inner tube, improving the coating effect. Next, the hot air enters the exhaust pipe through the air duct, the annular pipe, and the outer connecting pipe, blowing air onto the adhesive-coated inner tube. This helps accelerate the adhesive drying process, saving subsequent drying time and improving work efficiency. Attached Figure Description

[0022] Example 1: Please refer to Figures 1-12As shown, the present invention provides a technical solution: an inner tube coating device for tire processing, comprising a coating component 1 and an intelligent control system 2.

A connecting plate 310 is fixedly installed on the top of one side of the outer surface of the moving frame 303. The outer surface of the air outlet pipe 421 is fixedly installed on one side of the outer surface of the connecting plate 310. The outer surfaces of multiple sliding rods 412 are movably embedded inside the rotating guide bar 415. A fixing cylinder 403 is installed on the rear surface of the glue applicator 103 through an auxiliary plate. The outer surface of the rotating guide bar 415 is fixedly installed inside the fixing cylinder 403. An enlarged hole 407 is opened on the outer surface of the fixing cylinder 403. The outer surface of the magnifying lens 408 is fixedly installed inside the magnifying hole 407. Two slide bars 416 are fixedly installed on the inner wall of the fixed cylinder 403. A support slide 417 is movably embedded inside the two slide bars 416. The support slide 417 is fixedly installed on the outer surface of the other end of the fixed tube 404. A fixed plate 304 is fixedly installed on the rear surface of the moving frame 303. A rotating motor 305 is fixedly installed on the rear surface of the fixed plate 304. An adjusting roller 307 is installed on the outer surface of the rotating rod 306 through a reinforcing rod. I-shaped sealing rings 311 are movably embedded inside both sides of the adjusting roller 307. A sealing plate 312 is fixedly connected inside each of the two I-shaped sealing rings 311. A U-shaped sealing ring 313 is fixedly connected inside each of the two sealing plates 312.Two U-shaped sealing rings 313 are movably fitted onto the outer surfaces of both ends of the rotating rod 306. Moving holes 112 are provided on the front and rear surfaces of the top of the coating table 101. The outer surface of the movable frame 303 is movably embedded inside the two moving holes 112. One end of the rotating rod 306 extends movably through to the rear surface of the movable frame 303. The output end of the rotating motor 305 is fixedly connected to one end of the rotating rod 306. Four sliders 308 are fixedly installed on the outer surface of the movable frame 303. Slide rails 309 are movably fitted onto the bottom of each of the four sliders 308. The bottoms of the four slide rails 309 are fixedly installed on the front and rear surfaces of the top of the coating table 101. A mounting plate 302 is bolted to one side of the outer surface of the hydraulic rod 301. The top of the mounting plate 302 is fixedly installed on the bottom of the coating table 101.

[0023] In this embodiment, during use, the conveying system 102, the glue-applying motor 105, the metering glue pump 107, the hydraulic rod 301, the rotating motor 305, the camera 402, and the intelligent control system 2 are electrically connected. The glue-blocking plate 5 on the outer surface of the rotating shaft 106 and the glue-blocking plate 5 on the outer surface of the rotating rod 306 are staggered, so as not to affect the subsequent movement adjustment of the adjusting roller 307. The processed flat inner tube is placed on the conveying system 102 for conveying, and the glue-applying roller 104 applies glue to the surface of the inner tube to achieve the glue-applying process. The intelligent control system 2 sets the distance data that the adjusting roller 307 needs to move, then activates the hydraulic rod 301 to push the moving frame 303 to move inside the two moving holes 112, driving the adjusting roller 307, the corresponding two baffle plates 5, the fixed plate 304, and the rotating motor 305 to move together. Simultaneously, it drives the two annular pipes 418, the outer connecting pipe 419, and the air duct 420 to move together, and pulls the fixed pipe 404 to move, causing the support slide 417 to slide inside the slide bar 416. The rotating guide bar 415 consists of two transverse guide rails and one arc-shaped rotating guide rail, as shown... Figure 11 As shown, some of the magnifying rods 413 face downwards, and the corresponding slide rods 412 are embedded in the horizontal guide rail with the sliding hole facing downwards. Some of the magnifying rods 413 face upwards, and the corresponding slide rods 412 are embedded in the horizontal guide rail with the sliding hole facing upwards. Some of the magnifying rods 413 are spirally arranged, and the corresponding slide rods 412 are embedded inside the arc-shaped rotating guide rail, as shown. Figure 11 and Figure 12As shown. Through the cooperation of the limiting groove 409 and the limiting ring 410, when the fixed tube 404 moves, it will drive multiple scale rings 411 to move together, and drive the slide rod 412 to move inside the rotating guide bar 415. In the arc-shaped rotating guide rail, the slide rod 412 is guided to rotate and move spirally, so that the scale rings 411 drive the magnifying rod 413 to rotate and move spirally. When the slide rod 412 rotates downward, the magnifying rod 413 rotates upward. At this time, the corresponding scale number sticker 414 faces upward towards the magnifying lens 408. Through the magnifying effect of the magnifying lens 408, the numbers on the scale number sticker 414 are magnified, so that the camera 402 can capture clearer numerical scales and clearly detect the change in the moving distance of the fixed tube 404, that is, detect the moving distance of the moving frame 303, thereby judging the change in the moving distance of the adjusting roller 307 and improving the accuracy of distance detection. After the camera 402 captures a clear image of the digital scale, it transmits the image information to the intelligent control system 2. The intelligent control system 2 compares and analyzes the digital scale on the image with the set distance data. When the digital scale on the image matches the set data, the intelligent control system 2 controls the hydraulic rod 301 to automatically close, stopping the movement of the moving frame 303, thereby automatically adjusting the distance between the adjusting roller 307 and the glue dispensing roller 104, and adjusting the glue dispensing amount. With the cooperation of the moving adjustment component 3 and the distance monitoring component 4, intelligent and automated distance adjustment is achieved, and under the magnification of the magnifying lens 408... The camera 402 can capture clearer and more prominent numbers, more accurately detect changes in moving distance, and improve the accuracy and consistency of distance adjustment. This is beneficial for improving the quality of inner tube coating. It eliminates the need for manual adjustment of both ends of the steel roller, reducing manual intervention and saving manpower and time. It solves the problem of manually adjusting the position of the steel roller to adjust the amount of adhesive, which is cumbersome and makes it difficult to guarantee the accuracy and consistency of the adjustment at both ends. This can easily lead to inconsistent distances between the steel roller and the coating roller at both ends, affecting the quality of inner tube coating. The magnifying lens 408 can only capture the scale number 414 on the magnifying rod 413 that is just rotated upwards. As the fixing tube 404 continues to be pulled, the sliding rod 412 corresponding to the upward-facing magnifying rod 413 continues to move along the upward-facing transverse guide rail, allowing the upward-facing magnifying rod 413 to remain in this state as it moves from the magnifying lens 408 into the fixing cylinder 403, where it cannot be captured. This ensures that the camera 402 can only capture one accurately magnified number at a time, reducing interference from other numbers.

[0024] Example 2: Figures 1-6As shown, the glue application assembly 1 includes a glue application table 101 and a glue application roller 104. A glue application frame 103 is fixedly installed on one side of the top of the glue application table 101. A conveying system 102 is installed inside the glue application table 101. A metering glue pump 107 is installed on the top of the glue application frame 103. The input end of the metering glue pump 107 is connected to a glue application pipe 108 via a flange. A glue discharge pipe 109 is installed inside the glue application frame 103. One end of the glue discharge pipe 109 is connected to the output end of the metering glue pump 107 via a flange. A glue application motor 105 is installed on the rear surface of the glue application frame 103 via an auxiliary plate. A rotating shaft 106 is fixedly installed on the output end of the glue application motor 105. The glue application roller 104 is fixedly installed on the outer surface of the rotating shaft 106. One end of the rotating shaft 106 extends movably into the interior of the glue application frame 103, and the other end of the rotating shaft 106 is movably embedded in the front surface inside the glue application frame 103. The top of the glue-collecting table 101 is equipped with glue-collecting frames 111 near the moving hole 112. Two positioning plates 110 are fixedly installed on the other side of the top of the glue-collecting table 101. The outer surface of one side of the two glue-collecting frames 111 is movably embedded in the two positioning plates 110. Two slots 115 are opened on both sides of the top of the two glue-collecting frames 111. Four slots 113 are opened on the top of the glue-collecting table 101. The eight slots 115 are arranged in groups of two slots 115 in each longitudinal direction. Four corner locking rods 114 are movably embedded in the four groups of slots 115. The bottom ends of the four corner locking rods 114 are movably embedded in the multiple slots 113. The two sides of the inside of the moving frame 303 and the glue-collecting frame 103 are equipped with glue-blocking plates 5 through auxiliary rods. The four glue-blocking plates 5 are movably embedded on the outer surfaces of the rotating rod 306 and the two ends of the rotating shaft 106.

[0025] In this embodiment, during use, the distance between the adjusting rollers 307 is adjusted by moving the adjusting component 3 and the distance monitoring component 4, thereby adjusting the glue dispensing amount. Next, the processed flat inner tube is placed on the conveying system 102. One end of the glue application pipe 108 is connected to the glue storage tank. The metering glue pump 107 is started, and the glue is transported through the glue application pipe 108 to the glue discharge pipe 109, and finally to the space between the coating roller 104 and the adjusting roller 307. The rotating motor 305 and the glue application motor 105 are started in advance, driving the rotating rod 306 and the rotating shaft 106 to rotate, further driving the coating roller 104 and the adjusting roller 307 to rotate. Under the action of the adjusting roller 307, the outer surface of the coating roller 104 is evenly coated with glue. The conveying system 102 is started in advance to convey the inner tube. Passing under the bottom of the coating roller 104, the glue on the outer surface of the coating roller 104 is evenly coated onto the surface of the inner tube, thus completing the inner tube coating process. Next, the inner tube moves from the bottom of the adjusting roller 307 to the air outlet 421, where air is blown onto the inner tube to accelerate the curing of the adhesive. The inner tube is then conveyed to the drying area for further drying. Both ends of the adjusting roller 307 and the adhesive coating roller 104 are equipped with adhesive collection frames 111 to collect any adhesive dripping from these ends, preventing it from falling onto the equipment platform and causing contamination. The adhesive can also be recycled. Pulling the four corner levers 114 out of the slots 115 and 113 allows the adhesive collection frames 111 to be pulled outwards, facilitating the collection of recycled adhesive for reuse. When the glue collection frame 111 is placed back on top of the glue application table 101, the positioning plate 110 helps to position the glue collection frame 111, making it easier to quickly insert the four corner clips 114 into the slots 113 and 115 to fix the glue collection frame 111 and prevent it from shifting, which would affect the recycling of dripping glue.

One end of the connecting pipe 406 is fixedly connected to a telescopic pipe 405, and one end of the telescopic pipe 405 is fixedly connected to the connecting pipe 406. Both the front and rear surfaces of the movable frame 303 are fixedly connected to annular pipes 418. The outer surfaces of both annular pipes 418 are fixedly connected to external connecting pipes 419. The other end of the connecting pipe 406 is fixedly connected to one end of one of the external connecting pipes 419. One end of the other external connecting pipe 419 is fixedly connected to an air outlet pipe 421. Two air ducts 420 are fixedly connected to the outer surfaces of the two annular pipes 418. A connecting plate 310 is fixedly installed at the top of one side of the outer surface of the movable frame 303. The air outlet pipe 421... The outer surface is fixedly installed on one side of the connecting plate 310. The outer surface of the rotating rod 306 is equipped with an adjusting roller 307 via a reinforcing rod. I-shaped sealing rings 311 are movably embedded in the interior of both sides of the adjusting roller 307. Sealing plates 312 are fixedly connected inside the interior of the two I-shaped sealing rings 311. U-shaped sealing rings 313 are fixedly connected inside the interior of the two sealing plates 312. The two U-shaped sealing rings 313 are movably sleeved on the outer surfaces of both ends of the rotating rod 306. One end of each of the two air ducts 420 is fixedly inserted through the two baffle plates 5, the moving frame 303 and the two sealing plates 312 to the interior of the adjusting roller 307. One end of each of the other two air ducts 420 is fixedly inserted through the moving frame 303 and the two sealing plates 312 to the interior of the adjusting roller 307.

[0027] In this embodiment, during use, one end of the connecting pipe 406 is connected to an external hot air supply system. When the external hot air supply system is activated, hot air at a suitable temperature is delivered to the connecting pipe 406. The hot air then enters the fixed pipe 404 and one of the external pipes 419 through the telescopic pipe 405, and then enters the interior of the annular pipe 418. Finally, the hot air is blown into the interior of the adjusting roller 307 through the corresponding two air pipes 420. Through heat transfer, the heat is transferred to the adjusting roller 307, increasing the temperature of the adjusting roller 307, reducing the viscosity of the adhesive, making it more fluid, and making it easier for the coating roller 104 to adhere to the adhesive and to coat it evenly on the inner tube, thus helping to improve the coating effect. Next, the hot air in the regulating roller 307 enters another annular pipe 418 and outer pipe 419 through two other air pipes 420, and then enters the air outlet pipe 421. The air outlet end of the air outlet pipe 421 faces the direction of the conveying system 102, blowing the hot air evenly downwards to blow air onto the inner tube coated with glue, which helps to speed up the drying speed of the glue, save subsequent drying time, and improve work efficiency.

[0028] The method of use and working principle of this invention is as follows: start the hydraulic rod 301, push the moving frame 303 to move, drive the adjusting roller 307, the corresponding two baffle plates 5, the fixed plate 304 and the rotating motor 305 to move together, and at the same time drive the two annular pipes 418, the outer pipe 419 and the air pipe 420 to move together, and pull the fixed pipe 404 to move. With the cooperation of the limiting groove 409 and the limiting ring 410, the fixed tube 404 drives multiple scale rings 411 to move together, and drives the slide rod 412 to move inside the rotating guide bar 415. In the arc-shaped rotating guide rail, the slide rod 412 is guided to rotate spirally, so that the scale rings 411 drive the magnifying rod 413 to rotate spirally. When the slide rod 412 rotates downward, the magnifying rod 413 rotates upward. At this time, the corresponding scale number sticker 414 faces upward towards the magnifying lens 408. The magnifying lens 408 magnifies the numbers on the scale number sticker 414, making it easier for the camera 402 to capture clearer numerical scales. Then, the camera 402 transmits the captured image information to the intelligent control system 2. The intelligent control system 2 compares and analyzes the numerical scale on the image with the set distance data. When the numerical scale on the image matches the set data, the intelligent control system 2 controls the hydraulic rod 301 to automatically close, stopping the movement of the moving frame 303, thereby automatically adjusting the distance between the adjusting roller 307 and the coating roller 104. The processed flat inner tube is placed on the conveying system 102. The metering glue pump 107 is started, and glue is transported through the glue application pipe 108 to the glue discharge pipe 109, and finally the glue is transported between the coating roller 104 and the adjusting roller 307. The rotating motor 305 and the glue application motor 105 are started in advance, driving the rotating rod 306 and the rotating shaft 106 to rotate, which in turn drives the coating roller 104 and the adjusting roller 307 to rotate. Under the action of the adjusting roller 307, the outer surface of the coating roller 104 is evenly coated with glue. The conveying system 102 is started in advance to transport the inner tube. After passing under the coating roller 104, the glue on the outer surface of the coating roller 104 is evenly coated on the surface of the inner tube, thus completing the inner tube coating process. The glue collection frame 111 collects the glue dripping from both ends of the adjusting roller 307 and the coating roller 104. By pulling out the four corner levers 114 from the slots 115 and 113, the glue collection frame 111 can be pulled outwards to recover the glue. The external hot air supply system is activated, delivering appropriately heated air to the connecting pipe 406. This air then passes through the telescopic pipe 405 into the fixed pipe 404 and one of the external connecting pipes 419, then into the annular pipe 418. Finally, the hot air is blown into the adjusting roller 307 through the corresponding two air ducts 420, increasing the temperature of the adjusting roller 307, reducing the viscosity of the glue, improving its fluidity, and making it easier for the coating roller 104 to adhere to the glue, thus facilitating a more even coating on the inner tube.Next, the hot air in the regulating roller 307 enters another annular pipe 418 and outer pipe 419 through two other air pipes 420, and then enters the air outlet pipe 421. The air outlet end of the air outlet pipe 421 faces the direction of the conveying system 102, blowing the hot air evenly downwards to blow air onto the inner tube coated with glue, thereby accelerating the drying speed of the glue.

[0029] Among them, the conveying system 102, the glue application motor 105, the metering glue pump 107, the hydraulic rod 301, the rotating motor 305, the camera 402 and the intelligent control system 2 are all existing technologies, and their components and operating principles are all publicly available technologies, so they will not be explained in detail here.
