Description

Technical Field

[0001] The utility model belongs to the field of clothing processing equipment, and more specifically relates to a material pressing device for a clothing bag opening machine. Background Art

[0002] The fabric of the garment with a real pocket opening is divided into three layers, including garment fabric, outer pocket fabric and inner pocket fabric from the outside to the inside; the outer pocket fabric and the inner pocket fabric are sewn to form a pocket opening, and the pocket opening is located on the inner side of the garment fabric.

[0003] The processing method of this kind of clothing is as follows: 1. Fix the clothing fabric on the large pressing frame and open the bag and fold the edge through laser; 2. The large pressing frame carries the clothing fabric to press on the upper side of the outer bag fabric and performs the first sewing; 3. The large pressing frame carries the clothing fabric and the outer bag fabric to press on the upper side of the inner bag fabric and performs the second sewing.

[0004] In the above step 3, when the large press frame is moving, the clothing fabric is on its upper side and the outer pocket fabric is on its lower side. However, since the outer pocket fabric is only sewn to the folded pocket opening, the other parts of the outer pocket fabric are free. When the large press frame moves in the air, the outer pocket fabric will float down due to gravity and cannot fit with the bottom surface of the large press frame. As a result, when the large press frame is pressed on the inner pocket fabric, the outer pocket fabric cannot match and fit with the inner pocket fabric. After the second sewing, the shape of the pocket opening is unqualified.

[0005] In order to solve the above problems, the existing method is to set a mechanism to assist the fixing of the outer bag fabric under the large press frame. Generally speaking, a cylinder or a motor is used to lift the outer bag fabric from bottom to top through a push rod to ensure that the outer bag fabric fits the bottom surface of the large press frame. However, this method has a complex structure, high process and manufacturing costs, occupies a large space, and is easy to interfere with other components, so it is not conducive to large-scale application and promotion.
