Description

Technical Field

[0001] The invention relates to the technical field of clothing sewing equipment, and in particular to a feeding device directly used in a full-automatic cold folding bagging machine. Background Art

[0002] The main difference between the semi-automatic pocket sticking machine and the automatic pocket sticking machine lies in the application of its iron-free folding technology. The semi-automatic pocket sticking machine requires an electric heating steam folding machine to be installed next to the machine, and the folded and ironed bag mouth is placed on the feeding part of the pocket sticking machine for transmission and sewing, which is not only costly but also inefficient. The automatic pocket sticking machine directly uses the folding device to perform cold folding of the bag shape without heating and ironing: that is, a bag piece is placed on the bag-shaped template, and the folding knife on the folding frame of the folding device folds the two sides, front and two corners of the bag piece root. At this time, the folding frame and the bag-shaped template have a simultaneous falling action, pressing the folded bag on the work surface. When the folding knife of the folding frame is retracted and evacuated from the working area, the feeding plate or the receiving plate moves to the top of the bag-shaped template to press down the folded pocket. The bag-shaped template finally withdraws, and the folding mechanism rises and resets as a whole to end the folding process. Then, the folded pocket fabric and the body fabric are sent to the sewing assembly for sewing through the corresponding feeding device. The feeding device usually includes a pocket presser foot for pressing the pocket fabric and a body presser foot for pressing the body fabric. A sewing spacing corresponding to the shape of the pocket is left between the body presser foot and the pocket presser foot. Existing automatic pocket sticking machines usually can only correspond to one bag shape. If the bag shape changes, the hemming device and the feeding device cannot adapt to the new bag shape, and the compatibility is poor, resulting in an increase in production and processing costs, which is not conducive to energy saving and consumption reduction.

When the bag-shaped mold is pulled out from the pocket fabric and the body fabric, the piston rod of the pocket presser foot limit cylinder 55-8 is retracted downward, so that the fixed pressing plate 54-5, the front adjusting pressing plate 54-6, the left adjusting pressing plate 54-7 and the right adjusting pressing plate 54-8 continue to move downward from the top to press the pocket fabric tightly onto the body fabric. The feeding sewing drive device of the fully automatic cold folding bagging machine drives the feeding device 5 to feed the pocket fabric and the body fabric to the sewing machine of the sewing assembly for sewing. When the pocket to be sewn requires double stitches, after the outer stitches are sewn, the piston rods of the pocket left driving cylinder 55-2 and the pocket right driving cylinder 55-5 of the pocket presser foot driving device 55 are retracted upward, so that the fixed pressing plate 54-5, the front adjusting pressing plate 54-6, the left adjusting pressing plate 54-7 and the right adjusting pressing plate 54-8 are lifted from the pocket fabric, and then the piston rod of the pocket presser foot adjusting cylinder 54-2 of the feeding pocket presser foot 54 is retracted backward, and the front adjusting pressing plate 54-6, the left adjusting pressing plate 54-7 and the right adjusting pressing plate 54-8 are lifted from the pocket fabric. The section pressure plate 54-7 and the right adjusting pressure plate 54-8 move closer to the middle. After moving closer, the piston rods of the pocket left driving cylinder 55-2 and the pocket right driving cylinder 55-5 of the pocket presser foot driving device 55 extend downward, so that the fixed pressure plate 54-5, the front adjusting pressure plate 54-6, the left adjusting pressure plate 54-7 and the right adjusting pressure plate 54-8 press the pocket fabric again from above. At this time, the grooves between the pressure plates of the feeding pocket presser foot 54 and the feeding body presser foot 52 become larger, so that the corresponding stitches can continue to be sewn on the inner side of the first stitch.
