Among them, a cutting groove 13 is provided above the cutter 14 and the first driving assembly 15, which is lifted and lowered by a cylinder. The cutting groove 13 is N-shaped and corresponds to the cutting position of the cutter 14. When cutting the fabric, 13 presses the fabric and the cutter 14 realizes cutting.

[0036] like Figure 5 As shown, the material pulling mechanism 2 is arranged at the rear end of the feeding and cutting device 1, and is used to pull the fabric. The structure includes: a material pulling bracket 21 that can be displaced toward the feeding and cutting device 1. A fixed bracket 22 is arranged above the material pulling bracket 21, and the material pulling bracket 21 is slidably installed at the bottom of the fixed bracket 22 through a track 25. A second driving member 23 is fixedly arranged at the rear end of the fixed bracket 22. The second driving member 23 is a motor, and a driving screw 24 is arranged at the output end of the second driving member 23. The end of the driving screw 24 that is away from the second driving member 23 is installed on the fixed bracket 22 through a bearing seat, and the material pulling bracket 21 is connected to the driving screw 24 through a screw sleeve. The second driving member 23 drives the driving screw 24 to rotate to achieve the forward and backward displacement of the material pulling bracket 21.

[0037] The front end of the material pulling bracket 21 is provided with a clamping bottom plate 27 and a clamping upper plate 28 that are opened and closed by a clamping cylinder 26, and are used to clamp the end of the fabric. The clamping bottom plate 27 is fixed to the front end of the material pulling bracket 21, and the upper end surface of the clamping bottom plate 27 is provided with anti-slip teeth, and the lower end of the clamping upper plate 28 is provided with a protrusion that crosses and fits with the tooth groove 111.
