[0021] S3: Then control the motor to start, the start of the motor drives the rotation of the second rotating shaft, the rotation of the second rotating shaft drives the rotation of the second gear, the rotation of the second gear drives the rotation of the second gear to one side of the sector gear, the rotation of the second gear drives the rotation of the sector gear, the rotation of the sector gear drives the rotation of the second threaded rod, the rotation of the second threaded rod drives the reciprocating movement of the moving plate, and the movement of the moving plate drives the movement of the scraper block, so that the scraper block reciprocates once at the discharge port, and the residual material is scraped away;

[0022] S4: Then the second gear continues to rotate to drive the rotation of the first gear, the rotation of the first gear drives the rotation of the first rotating shaft, the rotation of the first rotating shaft drives the rotation of the second bevel gear, the rotation of the second bevel gear drives the rotation of the first bevel gear, the rotation of the first bevel gear drives the rotation of the first threaded rod, and the rotation of the first threaded rod drives the movement of the control plate, so that the coating material in the storage tank is discharged downward to the surface of the base material, and the base material is wound by the rotation of the winding roller,

[0026] 1. This invention, through the coordinated arrangement of a coating assembly and a scraping assembly, in the preparation of flame-retardant glass cloth silicone tape, firstly, the substrate is installed on the outer wall of the mounting roller, then unfolded and laid flat on the top of the worktable, with the end furthest from the mounting roller installed on the outer wall of the take-up roller. Then, the motor is started, and the start of the motor drives the second rotating shaft to rotate. The rotation of the second rotating shaft drives the rotation of the second gear, which in turn drives the rotation of the first gear. The rotation of the first gear drives the rotation of the first rotating shaft, which in turn drives the rotation of the second bevel gear. The rotation of the second bevel gear drives the rotation of the first bevel gear, which in turn drives the rotation of the first threaded rod. The rotation of the first threaded rod causes the control plate to move, causing the coating material inside the storage box to be discharged downwards onto the surface of the substrate. The take-up roller then rewinds the substrate, allowing it to be evenly coated by the coating knife during movement. The substrate continues to move, and the excess coating on both sides is scraped away by a scraper. Finally, a coating roller coats the coated substrate, and after coating, it enters a drying oven for drying, completing the preparation process.

[0027] 2. By setting up a rotating block, the present invention can drive the rotation of the third rotating shaft before preparation. The rotation of the third rotating shaft drives the rotation of the fourth bevel gear, which in turn drives the rotation of the third bevel gear. The rotation of the third bevel gear drives the rotation of the third threaded rod, which in turn drives the connecting plate to move. The movement of the connecting plate drives the movement of the scraper. The distance between the two scrapers can be adjusted to adapt to the preparation of tapes with different coating width requirements, thereby improving the adaptability of the device.

[0028] 3. By setting up the cleaning component, after coating is completed, the drive motor reverses, and similarly, the control plate moves to close the discharge port. The second gear continues to rotate, driving the sector gear to rotate. The rotation of the sector gear drives the rotation of the second threaded rod. The rotation of the second threaded rod drives the moving plate to move back and forth. The movement of the moving plate drives the scraper to move, so that the scraper scrapes at the discharge port to remove the residual material. This prevents some of the coating from adhering to the discharge port after coating due to the viscosity of the coating itself, which would affect the quality of the next coating.

[0045] By scraping off the excess coating on both sides of the coating area after coating, the quality of the final product is improved.

[0046] As shown in Figure 4 The inside of the scraper 21 is provided with a groove for storing materials.

[0047] The bottom end of the scraper 21 is obliquely arranged towards one side of the coating knife 5, and when the excess coating is scraped off, it is guided into the groove for temporary storage.

[0048] As shown in Figure 2 and Figure 3As shown, the two connecting plates 20 are both mounted on the outer wall of the third threaded rod 22, which is rotationally mounted in the interior of the coating frame 3. The outer wall of the third threaded rod 22 is fixedly mounted with a third bevel gear 23. The top end of the third bevel gear 23 is connected with a fourth bevel gear 24. The top end of the fourth bevel gear 24 is fixedly mounted with a third rotating shaft 25.
