[0062] The purpose of the present invention is to provide a multifunctional sewing device, which can improve the phenomenon that the traditional manual sewing process is time-consuming and labor-intensive in sewing pocket areas, so as to effectively improve the processing efficiency.

[0063] It should be noted that, in this embodiment, the X direction in the drawings is defined as the first direction, the Y direction is defined as the second direction, and the first direction is perpendicular to the second direction.

[0064] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 12In order to achieve the above-mentioned purpose, the present invention provides a multifunctional sewing device, comprising a working platform 1, a bag opening adjusting device 4, and a motion mechanism 11 connected to the working platform 1, a bag opening device 12, a bag folding device 5, a bag pressing device 6, a feeding device 7 and a sewing device 13.

The top of the loading lifting platform 71 is used to place the loading plate, and the piston rod of the loading cylinder 73 can be extended to drive the loading lifting platform 71 to move upward, so that the first magnetic suction component 32 magnetically attracts the loading plate, and keeps the bottom surface of the loading plate flush with the top of the work surface, or the bottom surface of the loading plate is slightly higher than the top of the work surface.

[0080] In summary, the multifunctional sewing equipment provided by the present application is moved to each processing area with the transition connection device 3 and the bag opening adjustment device 4 through the motion mechanism 11; the bag folding device 5 and the bag pressing device 6 are installed together and fixed under the bag folding and pressing station; the feeding device 7 is independently installed in another area of the working platform 1 and fixed under the feeding station, so that the bag folding and pressing station and the feeding station are located on both sides of the sewing device 13, which is convenient for loading at the feeding station. When the sewing equipment is used as a bag opening machine, the first cloth is fixedly placed at the preset position of the bag opening adjustment device 4 according to the cutting requirements, and is moved to the bag opening station below the bag opening device 12 through the motion mechanism 11. The bag is opened by laser through the bag opening device 12. After the bag is opened, it is moved to the bag folding and pressing station to fold the bag through the bag folding device 5. After the bag folding is completed, the bag pressing device 6 pushes the bag pressing plate to fit with the bag opening, and the bag pressing plate and the bag opening adjustment device 4 are sucked and fixed together. The bottom surface of the bag pressing plate is flush with the top surface of the working platform 1. The bag opening adjusting device 4 cooperates with the gear plate 42 and the transmission member 43 so that the short side moving seat 46 and the long side moving seat 410 move outward under the guidance of the third guide structure to expose the sewing area of the bag opening, and then moves to the loading station. The loading device 7 drives the loading lifting platform 71 through the loading cylinder 73 to push the loading plate to move to the bottom of the transition connection device 3 to form a whole, and keep the bottom surface of the loading plate flush with the top surface of the work table (or the bottom surface of the loading plate is slightly higher than the top surface of the work table), completing a loading action, and then moving to the sewing station to sew the bag opening through the sewing device 13. After completion, it moves to the loading station again for loading. After loading is completed, it moves to the sewing station to sew the bag opening again. After completion, it moves out of the sewing station, and the bag opening sewing process is completed. Repeating the above actions can carry out continuous bag opening and sewing production.
