[0003] Current mainstream resin grinding wheels mainly consist of resin grinding wheel raw materials and glass fiber mesh cloth. In actual production, the production process includes laying the mesh, placing the material, stamping, and sintering in a mold forming plate.

A limiting mechanism (6232) is arranged at the picking and placing rod (5231), and the limiting mechanism (6232) is used to realize the extension and retraction of the picking and placing rod (5231).

4. The fiberglass mesh feeding mechanism according to claim 3, characterized in that: The limiting mechanism (6232) includes material trays (3233) arranged at both ends of the picking and placing rod (5231). The material trays (3233) are relatively fixed to the picking and placing rod (5231). A through limiting hole (9238) is arranged at the center of the material tray (3233). A limiting cylinder (7236) is arranged at the center of the end of the material tray (3233) that cooperates with the picking and placing rod (5231). The limiting cylinder (7236) is used to cooperate with the limiting hole (9238) to realize the axial movement of the picking and placing rod (5231) along the center of the material tray (3233). A limiting cover (6235) is arranged at the top of the limiting hole (9238), and the limiting cover (6235) is used for the installation of the picking and placing rod (5231). A mating groove (7237) is arranged on the limiting cylinder (7236) along the moving direction of the push rod (5239), and the mating groove (7237) is used to realize the entry and exit of the second mating end (14239b) from the limiting cylinder (7236).

5. The fiberglass mesh feeding mechanism according to claim 4, characterized in that: The picking and placing rod (5231) includes a cylindrical picking and placing portion (11231b) arranged at the limiting hole (9238). The picking and placing portion (11231b) is slidably connected to the limiting hole (9238). A V-shaped material picking groove (11231c) is arranged at one end of the picking and placing portion (11231b). The thickness of the V-shaped material picking groove (11231c) is the same as that of a single fiberglass mesh cloth. A hemispherical mating portion (11231a) is arranged above the picking and placing portion (11231b). The mating portion (11231a) is used to cooperate with the second mating end (14239b) to realize the downward movement of the picking and placing rod (5231) along the limiting hole (9238). A limiting spring (6234) is arranged between the mating portion (11231a) and the material tray (3233), and the limiting spring (6234) is used for the reset of the picking and placing rod (5231).

6. The fiberglass mesh feeding mechanism according to claim 1, characterized in that: The main body of the feeding mechanism (221) further includes a material storage mechanism (226). The material storage mechanism (226) includes a material storage cylinder (226c) provided at the feeding station (229a). The material storage cylinder (226c) is used for storing fiberglass reels. A lifting cylinder (326a) is provided at the bottom of the material storage cylinder (226c). The lifting cylinder (326a) has a retractable lifting plate (326b), and the lifting plate (326b) is used for lifting the fiberglass reel.

7. Grinding wheel preparation device, characterized in that: It includes a device main body, and the device main body includes the fiberglass mesh fabric feeding mechanism according to any one of claims 1-6.
