[0020] The content of the present utility model will be further described in detail below in conjunction with specific embodiments:

[0021] Such as Figure 1As shown in the figure, a sewing device that synchronizes the cutting of rounded corners and edge wrapping is used to perform edge wrapping on a fabric while cutting the rounded corners of the four sides of the fabric. It includes a base 1, and a sewing machine 4 for sewing the edge onto the fabric is arranged on the base 1. A fabric driving mechanism that drives the fabric to move on the base 1 and enables the sewn part of the fabric to enter the head of the sewing machine 4. And a rounded corner cutter 5 fixed to the sewing machine 4 and arranged adjacent to the head of the sewing machine 4.

[0022] As Figure 3 shown in the figure, the rounded corner cutter 5 is fixed in the vertical direction and is located in front of the sewing needle of the sewing machine 4 relative to the fabric. Thus, the four corners of the square fabric enter the corresponding position of the rounded corner cutter 5 before entering the sewing needle of the sewing machine 4, that is, before the edge wrapping sewing. After being cut by the rounded corner cutter 5, they immediately enter the sewing needle of the sewing machine 4 for edge wrapping operation. It is realized that the fabric only needs to rotate one week to complete the operations of edge wrapping and cutting rounded corners.

[0023] As Figure 2 shown in the figure, the fabric driving mechanism includes fabric grippers 2. The fabric grippers 2 are arranged in a cross-shaped structure, and a moving module 3 is connected to the end far from the base 1. The moving module 3 includes a linear module 31 and a rotary module 32, and respectively drives the fabric grippers 2 to move along the horizontal plane and rotate around its own axis. Thus, it can drive the fabric into the head of the sewing machine 4 and drive the fabric to move clockwise or counterclockwise.

[0024] A plurality of adsorption holes 21 are opened at one end of the fabric gripper 2 close to the base 1. The plurality of adsorption holes 21 are all communicated with a negative pressure device arranged inside the fabric gripper 2. The fabric gripper 2 adsorbs the upper surface of the fabric through the adsorption force generated by the negative pressure device, thereby realizing the function of driving the fabric to move on the base 1.

[0025] Specifically, as Figure 2 shown in the figure, the moving module 3 includes a gantry erected on the base 1. The linear module 31 is fixed on the gantry and includes a guide rail 311 and a matching slider 312. Among them, a linear driver 313 is fixed at one end of the guide rail 311, and the execution end of the linear driver 313 is connected by a belt to a transmission wheel 314 arranged at the other end of the guide rail 311, and the slider 312 is fixed to the belt. The rotary module 32 includes a bracket 321 and a rotary driver 322. Among them, the bracket 321 is arranged in a C-shaped structure, and one end in the vertical direction is fixed to the slider 312, and the execution end of the rotary driver 322 penetrates through the bracket 321 in the vertical direction and is connected to the fabric gripper 2.

[0026] When in use:

[0027] Step 1: The fabric gripper 2 drives the fabric to enter the head of the sewing machine 4 from the previous process under the drive of the moving module 3, and makes the four corners of the fabric enter the corresponding positions of the rounded corner cutter 5.

[0028] Step 2: The fabric gripper 2 in the fabric driving mechanism performs translation and rotation under the combined drive of the linear module 31 and the rotary module 32, so that while the rounded corner cutter 5 cuts the fabric corners, the sewing machine 4 head then binds the fabric edge.
