The guide rail 11 is fixed on the horizontal plate 21. The guide rail 11 is located on a side wall of the horizontal plate 21 close to the clamping table 3, and the length direction is consistent with the width direction of the non-woven fabric. A slider 111 is slidably connected to the guide rail 11. The movable bracket 12 is fixed on the slider 111.

There are two movable plates 53, which are respectively located below the two ends of the storage roller 52, and the length direction of the movable plate 53 is perpendicular to the length direction of the storage roller 52. The pressure roller 54 is installed on the moving plate 53 through the bearing seat 101. The length direction of the pressure roller 54 is consistent with the length direction of the storage roller 52. There are multiple pressure rollers 54 on the moving plate 53, which are parallel to each other. The non-woven fabric in the unwinding frame 4 passes over the storage roller 52 and the pressure roller 54 in turn and then enters the cutting table 2. The storage roller 52 is attached to the lower surface of the non-woven fabric, and the pressure roller 54 is attached to the upper surface of the non-woven fabric. The side wall of the moving plate 53 is fixed with a guide ring 531, which is located in the middle of the moving plate 53. The guide column 55 is vertically fixed on the storage assembly frame 51. The guide column 55 passes through the guide ring 531, and the guide column 55 and the guide ring 531 are matched with each other. The electric telescopic cylinder 56 is installed on the storage assembly frame 51. The telescopic rod of the electric telescopic cylinder 56 is vertically fixed on the moving plate 53. The electric telescopic cylinder 56 can drive the moving plate 53 to move up and down.

[0028] Different cloths are passed over the storage roller 52 and the pressure roller 54 in turn, and are stacked, with the storage roller 52 in contact with the lower surface of the cloth and the pressure roller 54 in contact with the upper surface of the cloth. The cloth is then passed over the guide roller 6, and then passed through the gap between the horizontal plate 21 and the cutting table 2. Finally, the end edge of the cloth is clamped on the clamping claw 301 of the clamping table 3. The cloth can then be straightened by moving the clamping claw 301, and the movable plate 53 can be pressed down by using the telescopic cylinder 22, so that the cloth between the storage roller 52 and the clamping claw 301 can be tightened.

[0029] Reference Figure 6As shown, the unwinding frame 4 includes an unwinding assembly frame 41, a motor mounting frame 42, a driving motor 43, a driving gear 44, and a driven gear 45. The unwinding assembly frame 41 is composed of a plurality of square tubes. The unwinding assembly frame 41 and the material storage assembly frame 51 are connected to each other. The unwinding assembly frame 41 is provided with an air expansion shaft 411 for passing through the non-woven fabric roll. The air expansion shaft 411 is installed on the unwinding assembly frame 41 through a bearing seat 101, and multiple air expansion shafts 411 can be provided on the unwinding assembly frame 41, so that multiple rolls of non-woven fabric can be placed. The motor mounting frame 42 is fixed to the outer wall of the unwinding assembly frame 41, and one end of each air expansion shaft 411 is installed with a motor mounting frame 42. The driving motor 43 is installed on the motor mounting frame 42. The driving gear 44 is coaxially connected to the output shaft of the driving motor 43, and the driven gear 45 is coaxially connected to the end of the inflation shaft 411 and meshes with the driving gear 44. Each motor mounting frame 42 is equipped with a driving motor 43, a driving gear 44 and a driven gear 45.

[0030] The driving motor 43 drives the driving gear 44 to rotate, the driving gear 44 drives the driven gear 45 to rotate, and the driven gear 45 drives the air expansion shaft 411 to rotate, so that the non-woven fabric roll on the air expansion shaft 411 can be unwound. In addition, multiple rolls can be set at the same time, driven by different driving motors 43, so that multiple rolls of non-woven fabric can be unwound at the same time, and multiple rolls of non-woven fabric can be stacked.

[0031] Reference Figure 4 As shown, a guide roller 6 is provided on one side of the cutting table 2 close to the storage rack 5, and the guide roller 6 is installed on the side wall of the cutting table 2 through a bearing seat 101, and the non-woven fabric between the storage rack 5 and the cutting table 2 passes over the guide roller 6. The guide roller 6 can guide the non-woven fabric extending from the storage rack 5 so that the non-woven fabric will not contact the table surface of the cutting table 2, thereby reducing damage to the non-woven fabric.

[0032] This application can explain its functional principle through the following operation methods:

[0033] When it is necessary to cut different fabrics, such as cutting a glass fiber cloth roll and a non-woven fabric roll at the same time and making the glass fiber cloth and the non-woven fabric stacked, the different fabric rolls can be placed in the unwinding rack 4, and then the different fabrics can be extended to the storage rack 5, and then passed over the storage roller 52 and the pressure roller 54 in turn from top to bottom, and the different fabrics can be stacked, the storage roller 52 is attached to the lower surface of the fabric, the pressure roller 54 is attached to the upper surface of the fabric, and then the fabric is passed over the guide roller 6, and then the fabric is passed through the gap between the horizontal plate 21 and the cutting table 2, and finally the end edge of the fabric is clamped on the clamping claw 301 of the clamping table 3.

[0034] Afterwards, starting the drive motor 43 can automatically unwind the cloth roll, and the cloth can be pre-placed in the storage rack 5, and then the clamp 301 can straighten the cloth, and by using the telescopic cylinder 22, the movable plate 53 can be pressed down, so that the cloth between the storage roller 52 and the clamp 301 can be tightened. After tightening, the stepper motor 15 drives the synchronous wheel 141 to rotate, and the synchronous wheel 141 drives the synchronous belt 14 to move. Since the movable bracket 12 is fixed on the synchronous belt 14, it can drive the movable bracket 12 to move, and then the micro-cutting machine 13 on the movable bracket 12 can be moved, so that the non-woven fabric can be sheared. Therefore, before entering the cutting, it is realized that the roll is automatically unwound and the non-woven fabric is stored on the storage rack 5, and the non-woven fabric can be tightened, thereby improving the accuracy of shearing.
