Transfer device applied to robotic arm and production line for pulp molding

A transfer device for use with a robotic arm for pulp molding, the transfer device comprising:

• a wet blank transfer mold provided with a closed air chamber therein,
• wherein a front surface of the wet blank transfer mold is provided with at least one inward concave matching cavity capable of being sleeved outside a pulp wet blank container and recessed toward a closed air chamber side, the inward concave matching cavity is matched with the pulp wet blank container,
• wherein an inner wall of each inward concave matching cavity and a bottom of each inward concave matching cavity are respectively provided with a plurality of communicating holes connecting the inward concave matching cavity with the closed air chamber, the communicating holes disposed in the inner wall of each inward concave matching cavity are uniformly distributed circumferentially to form at least one circle, and the communicating holes disposed in the bottom of each inward concave matching cavity are uniformly distributed circumferentially to form at least one circle,
• wherein the wet blank transfer mold includes:
• a main mold plate provided with a chamber portion at a back surface, wherein the chamber portion has an opening communicating with the outside, a front surface of the main mold plate is provided with a plurality of the inward concave matching cavities distributed in an array, an inner bottom of the chamber portion is provided with a plurality of inward convex portions corresponding to the inward concave matching cavities one to one, and
• a closing mold plate for closing the opening of the chamber portion, wherein the closed air chamber is formed between the main mold plate and the closing mold plate;
• a moving frame connected in a parallel orientation to a back surface of the wet blank transfer mold via a guide mechanism;
• a driver connected between the back surface of the wet blank transfer mold and the moving frame and configured to drive movement of the moving frame to move relative to the wet blank transfer mold;
• and
• a plurality of vacuum suction cups disposed on the moving frame at uniform intervals on a side of the moving frame opposite the wet pulp transfer mold, the vacuum suction cups and the closed air chamber configured to be connected to a vacuumizing system.
