[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a coating device for processing adhesive patches, including a base plate 1, an unwinding mechanism 2 on one side of the top of the base plate 1, a substrate cloth 3 sleeved on the outer wall of the unwinding mechanism 2, a winding mechanism 4 on the other side of the substrate cloth 3, a support frame 5 on the top of the base plate 1 near the unwinding mechanism 2, a coating mechanism 6 rotatably connected to the opposite side of the support frame 5, a fixing frame 7 at the top of the support frame 5, a storage cylinder 8 sleeved on the inner wall of the fixing frame 7, a stirring mechanism 9 vertically penetrating the middle of the top of the storage cylinder 8, a drying box 10 on the top of the base plate 1 near the winding mechanism 4, a fan 11 screwed to the middle of the top wall of the drying box 10, and a flattening mechanism 12 screwed to the bottom wall of the support frame 5.
[0023] In this embodiment, as Figure 1 and Figure 5As shown, the unwinding mechanism 2 includes an unwinding frame 201 and an unwinding roller 202. The left and right ends of the unwinding roller 202 are rotatably connected to the opposite sides of the unwinding frame 201. The winding mechanism 4 includes a winding frame 401, a winding roller 402, and a first motor 403. The left and right ends of the winding roller 402 are rotatably connected to the opposite sides of the winding frame 401. The first motor 403 is inserted into one end of the winding roller 402. It should be noted that the operator can first place the base material 3 on the outer wall of the unwinding roller 202, and then pull out one end and place its end on the outer wall of the other winding roller 402. At the same time, the first motor 403 is started to drive the winding roller 402 inserted thereon to start rotating, so that the base material 3 originally placed on the outer wall of the unwinding roller 202... The substrate fabric 3 can be moved laterally towards the position of the take-up roller 402, and then undergo coating and drying operations in sequence before being wound up onto the outer wall of the take-up roller 402. In actual use, the design of the unwinding mechanism 2 allows the operator to easily place the substrate fabric 3 in a suitable position, facilitating subsequent processing. The rotational connection of the unwinding roller 202 ensures that the substrate fabric 3 is stably unwound when pulled, without jamming or deviation. The first motor 403 in the take-up mechanism 4 drives the take-up roller 402 to rotate, realizing automatic winding of the substrate fabric 3 after processing, saving manpower and improving production efficiency. At the same time, by controlling the speed of the first motor 403, the winding speed of the substrate fabric 3 can be precisely controlled, thereby better matching the production rhythm of the entire coating device.
[0024] In this embodiment, as Figure 2 and Figure 3As shown, the coating mechanism 6 includes an upper coating roller 601, a lower coating roller 602, a driving gear 603, a driven gear 604, and a second motor 605. The left and right ends of the upper coating roller 601 and the lower coating roller 602 are rotatably connected to the upper and lower ends of opposite sides of the support frame 5, respectively. The driving gear 603 is sleeved on the outer wall of one end of the lower coating roller 602, and the driven gear 604 is sleeved on the outer wall of one end of the upper coating roller 601. The second motor 605 is inserted into one end of the lower coating roller 602. It should be noted that when the operator stretches one end of the substrate cloth 3 on the surface of the unwinding roller 202 to the outer wall of the take-up roller 402, the end of the substrate cloth 3 can first pass directly under the lower coating roller 602, and then be fitted onto the outer wall of the take-up roller 402. At the same time, the first motor 403 and the second motor 605 are started. During this process, the second motor 605 will drive the lower coating roller 602, which is inserted with it, to start rotating, and will drive the lower coating roller 602 through the drive gear 603 fitted on the outer wall of its end. The driven gear 604 at the top enables the upper coating roller 601, which is connected to the driven gear 604, to rotate synchronously. At the same time, the viscous coating inside the storage cylinder 8 is transferred to the surface of the rotating upper coating roller 601. The upper coating roller 601, while rotating relative to the lower coating roller 602, transfers the viscous coating on its surface to the surface of the lower coating roller 602, so that it comes into contact with the surface of the substrate cloth 3, completing the coating operation. In actual use, the coating mechanism 6, through the relative rotation of the upper coating roller 601 and the lower coating roller 602 and gear transmission, can achieve precise coating of viscous coating on the substrate cloth 3, ensuring the uniformity and accuracy of the coating. Moreover, the synchronous rotation of the upper coating roller 601 and the lower coating roller 602 improves the coating efficiency, making the entire process smoother and enabling a large number of coating tasks to be completed in a short time. At the same time, by controlling the operation of the second motor 605, the coating speed and amount can be easily adjusted to adapt to different production needs and the characteristics of the substrate cloth 3.
[0025] In this embodiment, as Figure 2 and Figure 3As shown, a feed hopper 801 is vertically inserted through one side of the top of the storage cylinder 8. Several electric heating wires 802 are sandwiched in the inner wall of the storage cylinder 8. A dispensing box 803 is inserted into the bottom of the storage cylinder 8, and several brush bristles 804 are provided at the bottom of the dispensing box 803. It should be noted that when the operator starts the second motor 605 and drives the upper coating roller 601 and lower coating roller 602 to rotate synchronously via the drive gear 603 and driven gear 604, the operator can pour the viscous material from the feed hopper 801 into the storage cylinder 8, and simultaneously start the electric heating wires 802 and the stirring mechanism 9. This allows the viscous material inside the storage cylinder 8 to be heated and melted, causing the viscous coating to flow down the bottom of the storage cylinder 8 into the dispensing box 803 directly below. Once the viscous coating flows into the dispensing box 803, it will soak into the brush bristles 804 at its bottom. The brush bristles 804 are coated with viscous paint, and their bottom ends contact the upper and lower coating rollers 601. Therefore, as the upper coating roller 601 rotates, it fully contacts and coats the brush bristles 804 with sufficient viscous paint, facilitating subsequent coating operations. In practical use, the storage cylinder 8 stores viscous material, providing a continuous supply of raw materials for coating operations and avoiding frequent feeding that could affect production efficiency. The electric heating wire 802 in the inner wall layer heats and melts the viscous material, bringing it to a suitable state for coating, ensuring the fluidity and uniformity of the paint, which is beneficial for better coating. The viscous paint flows from the storage cylinder 8 into the distribution box 803, and then is evenly distributed onto the surface of the upper coating roller 601 through the brush bristles 804, ensuring uniform coating and preventing areas with too much or too little paint.
[0026] In this embodiment, as Figure 2 and Figure 3As shown, the stirring mechanism 9 includes a third motor 901, a stirring shaft 902, stirring rods 903, and a scraper 904. The third motor 901 is inserted into the top of the stirring shaft 902. Several stirring rods 903 are sleeved on the outer wall of the stirring shaft 902, and a scraper 904 is provided at the tail end of each stirring rod 903. It should be noted that when the operator pours the viscous material from the feed hopper 801 into the storage cylinder 8, the electric heating wire 802 and the third motor 901 can be started simultaneously. The third motor 901 will drive the stirring shaft 902, which is inserted into it, to start rotating, so that the stirring rods 903 sleeved on its outer wall can also rotate. The scraper 904 at the tail end of the stirring rod 903 will scrape against the outer wall of the storage cylinder 8. In addition to rotation, the heated viscous material turns into a liquid during this period and flows down the bottom of the storage cylinder 8 into the distribution box 803, where it soaks the brush bristles 804 and transfers the material to the lower coating roller 602. In practice, the stirring mechanism 9 can fully stir the viscous material in the storage cylinder 8, ensuring uniform heating and avoiding local overheating or undercooling, thus guaranteeing material consistency. The scraper 904 at the end of the stirring rod 903 scrapes against the inner wall of the storage cylinder 8, preventing the viscous material from settling or clumping on the cylinder wall and ensuring that the material is always in a good flow state, which is conducive to smooth flow into the distribution box 803 for coating. At the same time, the stirring mechanism 9 provides a stirring process that helps to accelerate the melting speed of the viscous material, resulting in better heating effect and improved production efficiency.
[0027] In this embodiment, as Figure 4As shown, the inner wall of the drying oven 10 is provided with a partition plate 1001 directly below the fan 11. Electric heating tubes 1002 are embedded in the inner walls of both sides of the drying oven 10. Through slots 1003 are opened on the outer walls of both sides of the drying oven 10. Several ventilation holes 1004 are opened on the top of the drying oven 10. A dustproof mesh plate 1005 is provided on the top of the drying oven 10 outside the ventilation holes 1004. It should be noted that after the substrate cloth 3 passes through the coating mechanism 6 and completes the adhesive material application, it will continue to move laterally under the drive of the winding mechanism 4 and pass laterally through the through slot 1003 opened on one side of the outer wall of the drying oven 10 into its interior. At the same time, the operator can simultaneously start the fan 11 and the electric heating tubes 1002. During this period, the fan 11 will draw outside air into its interior through the ventilation holes 1004. Simultaneously, the rotating fan blades will blow the air downwards. The air flows through the partition plate 1001 to the lower space of the drying chamber 10 and comes into contact with the electric heating tube 1002, thereby heating it up and turning it into hot air. This hot air then comes into contact with the substrate cloth 3 inside the chamber, thus drying the substrate cloth 3 coated with adhesive. After drying, the air is removed from the through groove 1003 on the other side of the drying chamber 10 and wound up. In actual use, the drying chamber 10 heats the air through the electric heating tube 1002. The generated hot air comes into contact with the substrate cloth 3 coated with adhesive, drying it quickly and ensuring the quality and performance of the adhesive patch. The ventilation hole 1004 at the top of the drying chamber 10 is equipped with a dustproof mesh plate 1005 to prevent external dust and other impurities from entering the drying chamber 10 and contaminating the substrate cloth 3 that is being dried. The fan 11 draws in and blows the air, forming an air circulation, which makes the temperature distribution inside the drying chamber 10 more uniform and improves the drying effect.
[0028] In this embodiment, as Figure 2 and Figure 3As shown, the flattening mechanism 12 includes an electric telescopic rod 1201 and a stop plate 1202. The bottom end of the electric telescopic rod 1201 is screwed to the bottom wall of the support frame 5, and the drive end of the electric telescopic rod 1201 is provided with the stop plate 1202. It should be noted that when the operator starts the winding mechanism 4 to move the substrate cloth 3 laterally so that it passes through the coating mechanism 6, the coating mechanism 6 will pass directly below the lower coating roller 602. At the same time, the operator can simultaneously start the electric telescopic rod 1201 through an external controller, so that its drive end extends upward and pushes the stop plate 1202 connected to it to rise together, so that the stop plate 1202 can contact the substrate cloth 3 located above it and push the substrate cloth. 3. This ensures that the substrate cloth 3 is always in contact with the surface of the lower coating roller 602, facilitating the coating operation. In actual use, the electric telescopic rod 1201 in the leveling mechanism 12 drives the abutment plate 1202 to rise, ensuring that the substrate cloth 3 is always in close contact with the surface of the lower coating roller 602, ensuring the stability of the material during the coating process, which is beneficial for uniform coating. The extension and retraction of the electric telescopic rod 1201 can be easily controlled by an external controller, thereby adjusting the position of the abutment plate 1202 to adapt to different substrate cloth 3 thicknesses or coating requirements. At the same time, the leveling mechanism 12 can also ensure good contact between the substrate cloth 3 and the lower coating roller 602, which helps to improve the coating quality and effect and reduce problems such as uneven coating caused by poor contact.
[0029] The method of use and advantages of this utility model: The coating device for processing adhesive patches operates as follows:
[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the operator first places the substrate cloth 3 on the outer wall of the unwinding roller 202, and then pulls out one end. The end of the substrate cloth 3 can be passed directly under the lower coating roller 602, and then placed on the outer wall of the take-up roller 402. At the same time, the first motor 403 and the second motor 605 are started. During this process, the second motor 605 will drive the lower coating roller 602, which is inserted with it, to start rotating. The drive gear 603, which is sleeved on the outer wall of its end, meshes with the driven gear 604 directly above it, so that the upper coating roller 601, which is sleeved with the driven gear 604, can also rotate synchronously. At the same time, the operator can pour the viscous material from the feed hopper 801 into the storage cylinder 8 and start the electric heating wire 802. Simultaneously with the stirring mechanism 9, the electric heating wire 802 and the third motor 901 are activated. The third motor 901 drives the stirring shaft 902, which is inserted into it, to rotate, causing the stirring rod 903, which is sleeved on its outer wall, to rotate as well. The scraper 904 at the end of the stirring rod 903 scrapes against the outer wall of the storage cylinder 8 during the rotation. During this process, the heated viscous material turns into a liquid, and the viscous coating flows down the bottom of the storage cylinder 8 into the dispensing box 803 directly below. After the viscous coating flows into the dispensing box 803, it soaks the bristles 804 at the bottom, so that each bristle 804 is covered with viscous coating. The bottom of the bristles 804 then comes into contact with the upper and lower coating rollers 601. Therefore, while the upper coating roller 601 rotates, it will fully contact the brush bristles 804 and pick up sufficient viscous coating. Simultaneously, as the upper coating roller 601 rotates relative to the lower coating roller 602, it transfers the viscous coating from its surface to the surface of the lower coating roller 602, bringing it into contact with the surface of the substrate cloth 3. During this process, the operator can simultaneously activate the electric telescopic rod 1201 via an external controller, extending its drive end upwards and pushing the connected abutment plate 1202 upwards. This allows the abutment plate 1202 to contact the substrate cloth 3 located above it, pushing the substrate cloth 3 to maintain constant contact with the surface of the lower coating roller 602, facilitating the coating operation. Once the substrate cloth 3 has passed through the coating mechanism 6 and completed the application of the viscous material... After the initial operation, the material will continue to move laterally under the drive of the winding mechanism 4 and pass through the through-slot 1003 opened on one side of the outer wall of the drying chamber 10 to enter its interior. At the same time, the operator can simultaneously start the fan 11 and the electric heating tube 1002. During this period, the fan 11 will draw outside air into its interior through the vent 1004. Meanwhile, the rotating fan blades will blow the air downwards, causing it to pass through the partition plate 1001 and flow to the lower space of the drying chamber 10, where it will come into contact with the electric heating tube 1002, thereby heating it up and turning it into hot air. This hot air will then come into contact with the substrate cloth 3 inside the drying chamber, thus drying the substrate cloth 3 coated with adhesive paint. After the drying process is completed, the material will be moved out from the through-slot 1003 on the other side of the drying chamber 10 and wound up.
