Description

Technical Field

[0001] The present invention relates to the technical field of garment processing equipment, and specifically relates to an adjustable bag mouth hemming device after bag mouth opening for garments. Background Art

[0002] A clothing pocket is a bag-shaped part sewn on clothes for holding things, also known as a pocket. Common ones include shirt pockets, suit pockets, and trouser pockets, etc. Suit pockets and some trouser pockets usually adopt a slit pocket (also known as an open pocket), that is, an opening is made on the main body fabric, and the pocket strip (some also have a pocket lip, a zipper or two layers of pocket pieces) is sewn on the inner side of the main body. Only the pocket opening can be seen from the outside, and this is also called a hidden pocket. After making the slit pocket, it is necessary to fold the edge at the pocket opening, folding the raw edge to the inside to make the edge more beautiful and durable. Chinese patent document CN117188053A discloses a folding mechanism for a clothing pocket-opening machine, which includes a bracket and a sliding seat that can be lifted and lowered on the bracket. A folding knife that can be pushed out outward under the drive of a driving member to achieve material folding is provided on the sliding seat. The folding knife includes a first folding knife, a second folding knife, a third folding knife, and a fourth folding knife that can enclose to form a rectangular outer contour. The first folding knife and the second folding knife are oppositely arranged in the length direction of the pocket opening that has been cut, and the third folding knife and the fourth folding knife are oppositely arranged in the width direction of the pocket opening that has been cut. It is characterized in that: the driving member includes a first driving member that can drive the first folding knife and the second folding knife to move outward synchronously to achieve material folding and a second driving member that can drive the third folding knife and the fourth folding knife to move outward synchronously to achieve material folding. In order to enable the second driving member to better drive the third folding knife and the fourth folding knife simultaneously, preferably, the output end of the second driving member is drivingly connected to a driving rod that can rotate around its own axis. Two oppositely arranged dial rods are also provided on the driving rod. Waist holes that can be adapted to the corresponding dial rods are respectively opened on the third folding knife and the fourth folding knife. When the second driving member drives the driving rod to rotate, the two dial rods can slide in the waist holes and push the third folding knife and the fourth folding knife to move synchronously and link outward or inward. Secondly, it is also recorded that: in order to enable the folding mechanism to be applicable to various models or specifications of fabrics, air blowing holes are specially arranged at intervals on the peripheral walls of the lower guide plate. The air blowing holes are located below and adjacent to the first folding knife, the second folding knife, the third folding knife, and the fourth folding knife. The air blowing holes can be connected to an external air source and can blow air at the fabric that has been bent by the first folding knife, the second folding knife, the third folding knife, and the fourth folding knife, so that the bent fabric can always maintain the bent state. Thus, the fabric that has been bent but sags due to its soft or thin material can be reset, further improving the processing quality and enabling it to be used for fabrics of various specifications or materials. It can be seen from this that the structure is relatively complex. By pushing the folding knife with a dial rod, gaps are easily generated, which may cause the extension or retraction to be in place, greatly reducing the use reliability. Secondly, the use of a cylinder to drive it has a fixed stroke and cannot be adjusted, and it cannot adapt to the hemming of pockets of different sizes. Summary of the Invention
