[0002] Medical breathable tapes are commonly used tapes in medical institutions, with good air permeability, softness, easy to unwind, convenient to operate, non-toxic and non-irritating. During the production process of medical tapes, it is necessary to scrape pressure-sensitive adhesive on the tape substrate to meet the use requirements.

[0003] In a glue coating device for medical breathable tapes with the retrieval publication number of CN217069421U, it includes an installation frame, a feeding roller and a discharging roller; the feeding roller is installed at the upper end of one side inside the installation frame, the discharging roller is installed at the lower end of the other side inside the installation frame, a discharging structure is arranged at the upper end inside the installation frame, and an adjusting structure is arranged at the lower end inside the installation frame. The discharging structure includes: a heating box body, a heating coil, a material tank, a mixing and discharging component and a discharging and coating component; the utility model relates to the technical field of tape production. The beneficial effect of this case is that the adopted discharging structure ensures the glue discharging state of the glue solution through the built-in heating coil. The adopted mixing and discharging component conveys the glue solution while mixing and stirring the glue solution, so that the glue solution can enter the glue discharging and coating component more smoothly, ensuring the glue coating effect of the tape.

[0004] However, when implementing the above technical solutions, there are the following problems: Although the device ensures the glue discharging state of the glue solution through the built-in heating coil, after glue coating, it is impossible to quickly dry the pressure-sensitive adhesive. Direct winding will cause the pressure-sensitive adhesive to overflow outside the winding under pressure, resulting in uneven distribution of the pressure-sensitive adhesive and affecting the use effect.

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please refer to Figures 1-4, an embodiment provided by the present utility model: a medical breathable tape pressure-sensitive adhesive scraping device, including a device main body 1 and a scraping and drying mechanism 3. A support frame 2 is arranged on the right side of the device main body 1, and a scraping and drying mechanism 3 is arranged on the top of the support frame 2.

A stirring rod 305 is arranged at the bottom of the first motor 304. A placement rack 306 is arranged on the left side of the storage tank 302, and a pump 307 is arranged at the top end of the placement rack 306. An output pipe 308 is arranged at the front end of the pump 307, and a glue application head 309 is arranged at the end of the output pipe 308. A partition plate 310 is arranged on the top end of the device main body 1, a scraping plate 311 is arranged inside the partition plate 310, a drying housing 312 is arranged on the left side of the scraping plate 311, a fan 313 is arranged on the top side inside the drying housing 312, and a drying heating pipe 314 is arranged at the bottom of the fan 313. A second roller 315 is arranged on the left side of the device main body 1, and a second motor 316 is arranged on the back of the second roller 315.

[0022] Further, the device main body 1 and the support frame 2 are welded, and the welding surface sizes of the device main body 1 and the support frame 2 are matched. Through such a setting, the structural stability between the device main body 1 and the support frame 2 is ensured, preventing loosening or vibration during operation, thereby ensuring the stability of the device and the reliability of long-term use.

[0023] Further, the storage tank 302 and the glue liquid heating pipe 303 are connected by screws, and the glue liquid heating pipes 303 are evenly distributed at the bottom of the storage tank 302. Through such a setting, the glue liquid heating pipes 303 can be evenly distributed at the bottom of the storage tank 302. The evenly distributed glue liquid heating pipes 303 can ensure that the temperature of the glue liquid is uniform during the heating process, avoiding local overheating or insufficient temperature, thereby ensuring the quality and stability of the glue liquid, and being beneficial to the uniformity and quality of subsequent glue application operations.

[0024] Further, the first motor 304 and the stirring rod 305 are fixedly connected, and the stirring rod 305 extends to the bottom of the storage tank 302. Through such a setting, it is ensured that the first motor 304 can effectively drive the stirring rod 305, thereby evenly stirring the glue liquid in the storage tank. The stirring rod 305 extending to the bottom ensures that the entire glue liquid can be fully stirred, avoiding precipitation or stratification of the glue liquid during storage, and ensuring the uniformity and stability of the glue liquid.

[0025] Further, the slotting connection is adopted between the doctor blade 311 and the partition 310, and the doctor blade 311 is closely attached to the partition 310. Through such a setting, the stable connection between the doctor blade 311 and the partition 310 during the doctoring process is ensured, which can effectively prevent the doctor blade from shifting or loosening, guarantee the uniformity of the pressure-sensitive adhesive during the doctoring process, and thus improve the quality.

[0026] Further, the fan 313 and the drying housing 312 are connected by screws, and the drying heating tube 314 and the drying housing 312 are connected by screws. Through such a setting, it is ensured that the heat can be effectively transferred to the surface of the breathable tape, thereby improving the drying efficiency and production speed and guaranteeing the quality of the product.

[0027] Further, the second motor 316 and the second roller 315 are fixedly connected, and the second roller 315 is driven by the second motor 316 to rotate. Through such a setting, it is ensured that the second motor 316 can stably drive the rotational movement of the second roller 315, and it can ensure that the breathable tape maintains a constant speed and tension during the processing, avoiding unevenness during the processing, and guaranteeing the quality of the product.

[0028] Working principle: During use, first, the whole roll of pressure-sensitive adhesive breathable tape to be doctored is fixed on the first roller 301, and then it is pulled out until one end of it is fixed on the second roller 315. The second motor 316 drives the second roller 315 to rotate, driving the first roller 301 to rotate, causing the breathable tape to move horizontally on the device main body 1. Then, the glue heating tube 303 is located at the inner bottom of the storage tank 302. The stirring rod 305 driven by the first motor 304 evenly stirs the glue, and the glue heating tube 303 heats the glue to ensure that the glue maintains fluidity and viscosity within an appropriate temperature range. Then, the pump 307 at the top of the placement rack 306 introduces the glue through the storage tank 302. The pump 307 transports the glue to the glue applicator head 309 through the output pipe 308. The glue applicator head 309 is located at the end of the output pipe 308 and is responsible for evenly coating the glue on the medical breathable tape. The slotting connection is formed between the doctor blade 311 and the partition 310, and the pressure-sensitive adhesive on the doctor blade 311 is evenly applied to the surface of the breathable tape during the doctoring process. After the doctoring is completed, the breathable tape enters the drying housing 312. Inside the drying housing 312, the fan 313 dries the pressure-sensitive adhesive coated on the breathable tape through the drying heating tube 314 at the bottom. The airflow generated by the fan 313 enables the heat of the drying heating tube 314 to be evenly transferred to the surface of the breathable tape, thereby accelerating the curing and drying process of the pressure-sensitive adhesive, avoiding the unevenness of the glue or the overflow of the glue outside the roll before the drying of the pressure-sensitive adhesive, and ensuring that the breathable tape meets the ideal quality and performance requirements during the manufacturing process. In this way, the use process of a pressure-sensitive adhesive doctoring device for medical breathable tape is completed.
