摘要： A plastic thread bonding method and structure for folding edge of a FIBC includes setting the folding edge of the FIBC flatly on a metal solid surface; using a cooling device to maintain a condensation temperature of the solid surface; performing a needle insertion action of the folding edge by a plastic injection needle, and condensing and crystallizing at the eyelet to form a base point; performing a needle withdrawal action by the plastic injection needle to fill up a melted plastic into the eyelet, applying a pressurized cold air to condense the melted plastic to from a thread post; performing a horizontal translation action of the plastic injection needle or the folding edge, and applying the pressurized cold air to condense the melted plastic to form a thread bridge; and repeating the aforementioned procedure to form a next base point, a next thread post and a thread bridge.

摘要： A bag clamping and sealing machine includes a first top bar, a second top bar, a first bottom bar and a second bottom bar movable along a horizontal X-axis. A first top board, a second top board, a first bottom board and a second bottom board movable along a horizontal Y-axis which is perpendicular to the horizontal X-axis. The first top bar and the second top bar, and the first bottom bar and the second bottom bar move toward each other to clamp a bag opening of a bag to be a flattened portion. The first top board and the second top board, and the first bottom board and the second bottom board move toward each other to narrow the flattened portion to be an elongate portion. A robotic arm firmly clamps the elongate portion between a C-clip and an I-bar.
