The application provides a special-shaped bead piece embroidery device and relates to the field of bead piece embroidery. The device comprises a base, a first driving
assembly is installed at the bottom of the base, a supporting frame is installed at the top of the first driving
assembly, a control member is installed on the outer wall of the right supporting frame, a second driving
assembly is installed at the top of the supporting frame, a third driving assembly is installed at the front end of the second driving assembly, and a bead piece embroidery
machine head is installed on the outer wall of the third driving assembly. The multi-dimensional carrier tape supply module is configured with an active feeding, a PID closed-loop
tension control and an air floating support unit. The guide rail adopts
a diamond-like
carbon film low-friction
coating, and the bottom of the cooperation rail is provided with a micropore array to form a uniform
air cushion, so that the special-shaped bead piece is in a nearly frictionless suspension state, and the problems of snakelike swinging, gravity deviation, tension fluctuation, carrier tape stretching deformation and material stacking in high-speed conveying are effectively inhibited. The device is suitable for the continuous and stable conveying of asymmetric special-shaped bead pieces such as water-drop-shaped, star-shaped and polygonal bead pieces, and the conveying reliability and speed are improved.
