The sewing machine can sew fabrics such as cotton, linen, silk, wool, and man-made fibers, as well as products such as leather, plastic, and paper. The stitches sewn are neat, beautiful, flat and firm, the sewing speed is fast, and it is easy to use.

[0003] When the existing sewing machine is in use, the position of the fabric to be sewn is fixed, which makes it difficult to sew the side far from the sewing head. Moreover, when loading materials, manual loading is required, and when collecting materials, manual collection is required. Therefore, a full-automatic four-side sewing machine is proposed. Content of the Utility Model

[0004] To solve the above at least one technical defect, the utility model provides a full-automatic four-side sewing machine, which includes a machine table. The machine table is composed of two side plates and a top plate fixed to the tops of the two side plates. The inner edge of the top plate is fixedly connected with a vertical sliding table module. A horizontal sliding table module is slidably connected to the vertical sliding table module. A rotary sewing control head is arranged on the sliding end of the horizontal sliding table module. The horizontal sliding table module supplies power to the rotary sewing control head through a power supply drag chain. The outer edge of the top plate is fixedly connected with a sewing head sliding mechanism, and a sewing head is arranged at the sliding end of the sewing head sliding mechanism.

[0005] Further, a feeding mechanism is arranged at the left end of the inner edge of the top plate. A needle-type material picker is arranged at the sliding end of the feeding mechanism. An automatic feeding tray is arranged directly below the needle-type material picker, and the automatic feeding tray is located between the two side plates.

[0006] Further, a material collection bin is arranged at the right end of the two side plates. A material collection cylinder fixed to the right end of the top plate is arranged directly above the material collection bin. A material collection pneumatic clamping mechanism is arranged at the telescopic end of the material collection cylinder.

[0007] Further, universal wheels are arranged at the bottom of the side plates.

[0008] Further, the top plate is an anti-formica board, and a number of bull's eyes are evenly arranged on the upper surface of the top plate. Beneficial Effects

[0009] When sewing, the vertical sliding table module drives the horizontal sliding table module to move horizontally, the horizontal sliding table module drives the rotary sewing control head to move horizontally, the rotary sewing control head drives the fabric to rotate, the sewing head sews the four sides of the fabric, and the sewing head sliding mechanism controls the movement of the sewing head.

[0010] When feeding materials, the raw materials are stacked on the upper surface of the automatic feeding tray, and the raw materials are clamped and fed by a needle-type material picker. The raw materials are sent from the automatic feeding tray to the sewing area through a feeding mechanism.

[0011] When automatically collecting materials, the telescopic end of the collecting cylinder extends, and the sewn fabric is clamped by the collecting pneumatic clamping mechanism. Then, the collecting cylinder contracts to place the fabric inside the collecting bin, completing the material collection.

[0012] The top plate is an anti-formica board, and a number of bull's-eye beads are evenly arranged on the upper surface of the top plate, so as to achieve low resistance and make the material smoother.
