[0038] Please refer to again Figures 1 to 6 , a fully automatic sheet folding and hemming sewing mechanism according to an embodiment of the present invention, and its specific operation principle is as follows:

[0039] S1: Place the sheet on the hemming station 2 manually or automatically.

[0040] S2: Then, the first lifting module 34 on the hemming positioning mechanism 3 drives the positioning pressing plate 35 to descend, so that the positioning pressing plate 35 presses and positions on the sheet, making the sheet immovable.

[0041] S3: The hemming piece 43 of the hemming mechanism 4 is initially located below one side of the sheet. Then, the second lifting cylinder 42 of the hemming mechanism 4 drives the hemming piece 43 to rise on one side of the sheet, so that the hemming piece 43 exceeds one side of the sheet. At this time, one side of the sheet is concave inward in the inverted "L" shape of the hemming piece 43. Then, the second lifting cylinder 42 drives the hemming piece 43 to descend, so that the hemming piece 43 presses and folds one side of the sheet.

[0042] S4: The first retracting cylinder 31 on the hemming positioning mechanism 3 drives the first lifting module 34 to linearly retract (to avoid interference with the hemming piece 43 of the hemming mechanism 4). Then, the first lifting module 34 on the hemming positioning mechanism 3 drives the positioning pressing plate 35 to rise and reset.

[0043] S5: Place the sewing tape on the sheet at the hemming station 2 manually or automatically.

[0044] S6: The third lifting cylinder 52 of the first sewing tape pressing and positioning mechanism 5 drives the first sewing tape positioning pressing piece 53 to press down, so that one end of the sewing tape is positioned and pressed. The left and right cylinders 62 of the second sewing tape pressing and positioning mechanism 6 drive the second sewing tape positioning pressing piece 63 to approach the other end of the sewing tape. Then, the fourth lifting cylinder 61 of the second sewing tape pressing and positioning mechanism 6 drives the second sewing tape positioning pressing piece 63 to press down, so that the other end of the sewing tape is positioned and pressed.

[0045] S7: The rotation drive motor 71 of the sheet folding mechanism 7 drives the first folding shaft 72 to rotate, and the first folding shaft 72 drives the folding plate 73 to rotate, so that the sheet is folded. The other end of the rotating folding plate 73 rotates in the shaft hole at one end of the second folding shaft 74, and the other end of the second folding shaft 74 is fixedly connected to the hemming workbench 1.

[0046] S8: After completing the above steps S1 - S6, the folding piece and the hemming of the sewing belt are completed. The folding piece folding mechanism 7 resets, the first sewing belt pressing and positioning mechanism 5 resets. At the same time, the third retracting cylinder 51 drives the third lifting cylinder 52 to retract and reset (facilitating the removal of the folding piece and the sewing belt). The second sewing belt pressing and positioning mechanism 6 resets, and the hemming mechanism 4 resets. Then, the folding piece and the sewing belt are transferred into the sewing machine through manual or automated actions for sewing.

[0047] An automatic folding piece hemming and sewing mechanism according to an embodiment of the present invention can automatically achieve hemming of the folding piece and the sewing belt, efficiently and quickly, reducing the labor intensity of workers.

[0048] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
