Description

Technical Field

[0001] The utility model belongs to the technical field of sewing equipment and relates to a tongue plate telescopic device and a pocket pasting machine. Background Art

[0002] In the process of sewing clothes, pockets are often needed to be sewn. Before sewing the pockets, three sides of the pocket cloth need to be folded, and then the three sides of the pocket cloth are sewn with other fabrics to form pockets.

[0003] During the sewing process, the edge of the pocket cloth needs to be tightly attached to other fabrics. Therefore, a clamping structure is needed, such as the feeding mechanism for a pocket sticking machine provided by application number 201220507371.5, which uses an auxiliary presser foot and an external presser foot to clamp the material together, and the bag piece (pocket cloth) is fixed to the fabric.

[0004] The disadvantage of the prior art is that after the pocket cloth is closely attached to other cloths, it is difficult to refold it, which has certain limitations. Summary of the invention

[0005] The utility model aims at the above problems existing in the prior art and provides a tongue plate retracting device. The technical problem to be solved by the utility model is: how to refold pocket cloth.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A tongue plate extension and retraction device comprises a tongue plate, wherein a guide plate is arranged on the tongue plate, and is characterized in that a movable pressure plate 1 and a movable pressure plate 2 are arranged on the guide plate, and a driving member for driving the pressure plate 1 and the pressure plate 2 to move closer to or away from each other is also arranged on the tongue plate.

[0008] The working principle is as follows: the tongue plate retracting device is used in conjunction with the folding device and the material pressing and shifting device.

[0009] The pocket pasting machine includes a workbench. When in use, a piece of body fabric is placed on the workbench, the entire tongue plate retractable device extends from the top of the workbench, the tongue plate is located above the body fabric, and the driving member drives the pressing plate one and the pressing plate two to move away from each other, and then the pocket fabric is buckled on the pressing plate one and the pressing plate two, and the three adjacent sides of the pocket fabric extend downward respectively. After the folding device folds the corresponding sides of the pocket fabric toward the direction close to the tongue plate retractable device, the folding device and the tongue plate retractable device descend together, so that the three edges of the pocket fabric are in contact with the body fabric and are pressed against the workbench by the tongue plate retractable device. After the folding is completed, the folding device leaves the tongue plate retractable device.

[0010] After that, the inner pressure frame of the pressure and transfer device moves to the top of the pocket fabric and presses down. After pressing into place, the driving part drives the pressure plate 1 and the pressure plate 2 to approach each other. Then, the three pressing plates of the inner pressure frame move inward to press (fold) each edge of the pocket fabric (a total of three edges) respectively. The bottom of the three edges of the pocket fabric exposes the edge of the fabric to be sewn. Then, the entire tongue plate retracting device retracts, and the pressure and transfer device moves to the needle of the pocket sticking machine. The needle sews the edge of the fabric to complete the sewing of the three-dimensional pocket.

[0011] The driving member of the tongue plate retracting device first stretches the pressing plate 1 and the pressing plate 2 apart, and then puts the pocket fabric on the pressing plate 1 and the pressing plate 2. After the pocket fabric is folded for the first time, the driving member drives the pressing plate 1 and the pressing plate 2 to shrink, leaving space so that the inner pressing frame can refold the three sides of the pocket fabric, which is well adapted to the requirements of various sewing processes.
