Integrating multiple functions, it encompasses precision spraying and scraping, and is adaptable to both liquid and semi-paste-like microcapsule raw materials, greatly expanding its application scenarios. Its main components include: a raw material storage tank, divided into liquid and semi-paste material storage areas to ensure raw material supply; a precision spraying system, containing high-precision nozzles and a flexible robotic arm, to achieve precise atomization spraying of liquid raw materials; a scraping system with a scraper and matching support, responsible for the uniform spreading of semi-paste-like raw materials; an automatic heating device, using temperature sensors and heating elements for precise temperature control; and a stirring component to prevent raw material stratification and sedimentation.
[0003] However, the height of the scraper blades in existing machines cannot be adjusted. When faced with workpieces or irregular objects with different thickness requirements, it is difficult to flexibly control the coating thickness, which easily leads to uneven coating. This affects the adhesion of microcapsules and product quality, and limits the efficient application of equipment in complex process scenarios. Utility Model Content

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Reference Figures 1 to 4 This utility model provides an embodiment of a novel microcapsule-specific spraying device, comprising a base plate 9, a spraying platform 1 fixedly connected to the middle of the outer wall of the base plate 9, and movable plates 10 fixedly connected to both sides of the outer wall of the spraying platform 1. A hollow block 3 is slidably connected to the top wall of one movable plate 10, and a threaded rod 4 is threadedly connected to the middle of the hollow block 3. A connecting block 5 is fixedly connected to the outer wall of the threaded rod 4. The base plate 9 serves as a basic support component, supporting the entire device. The spraying platform 1 in the middle of its outer wall is the core operating area, where raw material processing, spraying, and scraping are completed. The movable plates 10 on both sides are used to install other components. The hollow block 3 cooperates with the threaded rod 4 and the connecting block 5. When the threaded rod 4 is rotated, it can drive the connecting block 5 to move, precisely controlling the position of the relevant components and ensuring the accuracy of scraping.
[0023] One end of the connecting block 5 is fixedly connected to a long plate 6. A slider 7 is fixedly connected to the left side of the outer wall of the long plate 6. A slide rail 8 is slidably connected to the outer wall of the moving plate 10. A lifting mechanism 2 is provided on the front side of the outer wall of the spraying platform 1. The lifting mechanism 2 is used to close the discharge port of the spraying platform 1. The slider 7 is slidably connected to the slide rail 8. A scraper 17 is fixedly connected to the bottom wall of the long plate 6. The long plate 6 at one end of the connecting block 5 is used to expand the operating space. The slider 7 on the long plate 6 cooperates with the slide rail 8 of the moving plate 10. When the threaded rod 4 is rotated, the long plate 6 is ensured to move smoothly laterally and the scraper 17 is accurately positioned. The lifting mechanism 2 on the front side of the spraying platform 1 can accurately control the opening and closing of the discharge port to prevent raw material leakage and ensure stable operation of the equipment.
[0024] A second heating stirrer 15 is fixedly connected to one side of the top wall of the base plate 9. The outer wall of the second heating stirrer 15 has a pipe 16. A spraying arm 14 is fixedly connected to the top wall of the base plate 9. A precision nozzle 13 is located at the top of the spraying arm 14 and is connected to the pipe 16. A first heating stirrer 11 is fixedly connected to one side of the top wall of the base plate 9. A transfer port 12 is installed on the outer wall of the first heating stirrer 11. The first heating stirrer 11 on the base plate 9 receives raw materials through the transfer port 12 and prevents stratification by stirring, thus preparing uniform materials for subsequent processing. Similarly, the second heating stirrer 15 has a pipe 16 on its outer wall for conveying raw materials. The precision nozzle 13 at the top of the spraying arm 14 is connected to the pipe 16, which can accurately atomize and spray the raw materials to meet the fine spraying requirements of microcapsule coating.
[0025] The lifting mechanism 2 includes a hollow shell 201, which is fixedly connected to the front side of the outer wall of the spraying platform 1. A rotating rod 202 passes through the inner wall of the hollow shell 201, and a gear 203 is fixedly connected to one end of the rotating rod 202. A slide rail 207 is fixedly connected to the front side of the outer wall of the spraying platform 1. The hollow shell 201 serves as the outer shell of the lifting mechanism 2 and is fixed to the front side of the outer wall of the spraying platform 1, playing a role in protecting and supporting the internal components. The rotating rod 202 passes through the hollow shell 201 and is a power input component. Rotating it can drive the gear 203 at one end to rotate. The slide rail 207 on the front side of the outer wall of the spraying platform 1 serves as a guide for the movement of subsequent components, and together they achieve precise opening and closing control of the discharge port.
[0026] A baffle 205 is provided on the right side of the outer wall of slide rail 207. A slider 206 is fixedly connected to the left side of baffle 205. A rack 204 is fixedly connected to the right side of the outer wall of baffle 205. The rack 204 meshes with the gear 203. The slider 206 is slidably connected to slide rail 207. The gear 203 is set on the inner wall of hollow shell 201. Slide rail 207 provides a stable sliding track for baffle 205 and slider 206 to ensure linear motion accuracy. Baffle 205 is used to open and close the discharge port of spraying platform 1. The slider 206 on the left side cooperates with the slide rail for guidance to ensure smooth movement. The rack 204 on its right side meshes with the gear 203 inside hollow shell 201. Rotating rod 202 drives gear 203 to rotate, thereby precisely driving baffle 205 to rise and fall.
[0027] Working Principle: In the raw material processing stage, the heating agitator 11 on one side of the top wall of the base plate 9 and the heating agitator 25 on the other side each perform their respective functions. Heating agitator 11 transmits raw materials to the spraying platform 1 through the transmission port 12. Its internal stirring device operates continuously to thoroughly stir the raw materials, effectively preventing material stratification and ensuring uniform mixing of all components, laying the foundation for subsequent processing. Similarly, the raw materials stirred by heating agitator 215 are transported through the pipe 16 on the outer wall into the scraping process. The scraper blade 17 at the bottom of the long plate 6 is crucial. The scraper blade 17 adopts a special material and process design, and the blade has an appropriate... Its flexibility and smoothness allow it to closely adhere to the spraying platform 1 when scraping semi-paste-like microcapsule raw materials, spreading the raw materials evenly without damaging the wall material of the microcapsules due to excessive squeezing or friction, thus ensuring the integrity of the microcapsule structure. Rotating the threaded rod 4, the connecting block 5 and the long plate 6 are moved by the threaded connection with the hollow block 3, and the slider 7 slides stably along the slide rail 8, precisely adjusting the lateral position of the scraper blade 17 to achieve efficient and uniform scraping. During the spraying stage, the precision nozzle 13 connected to the pipe 16 is installed at the top of the spraying arm 14, and can be precisely atomized and sprayed out after the raw materials arrive, meeting the microcapsule coating requirements of fine products.
[0028] Furthermore, when it is necessary to control the closing state of the discharge port of the spraying platform 1, the lifting mechanism 2 starts to operate. The rotating rod 202 serves as a power input component. When an external force rotates the rotating rod 202, the gear 203 fixed at one end rotates synchronously. Since the gear 203 is meshed with the rack 204 fixed on the right side of the outer wall of the baffle 205, the rack 204 will be driven to make linear motion during the rotation of the gear 203. Meanwhile, the slider 206 on the left side of the baffle 205 is slidably connected to the slide rail 207 on the front side of the outer wall of the spraying platform 1. This provides guidance for the stable linear movement of the baffle 205, ensuring that the baffle 205 can only slide up and down along the slide rail 207. When the gear 203 rotates in the forward direction, the rack 204 drives the baffle 205 to rise, opening the discharge port and facilitating the flow of raw materials for subsequent processing. Conversely, when the gear 203 rotates in the reverse direction, the baffle 205 descends, precisely closing the discharge port to prevent raw material leakage and ensure the stability and processing accuracy of the equipment.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
