These fabrics not only affect the appearance of the sofa, but are also directly related to the user experience. Common sofa fabrics include technical cloth, top-layer cowhide, genuine leather, linen, canvas, velvet, etc. When the fabric is processed, it needs to be cut to facilitate making a sofa of suitable size.

[0003] In the prior art, it is troublesome to adjust the position of the cutter for cutting sofa fabrics. It is necessary to use a hexagonal wrench to turn multiple hexagonal screws to adjust the distance between the cutters to meet the requirements of different cutting widths. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a sofa fabric cutting device, which solves the problem in the prior art that a hexagonal wrench needs to be used to screw multiple hexagonal screws to adjust the distance between the cutters.

[0006] In this scheme, the fabric is sleeved on the unwinding roller, and the insertion shaft is rotated, and then the reciprocating groove is rotated, and a driving force is applied to the clamping plate. At the same time, under the limit of the square groove, the clamping plate can be adjusted according to the width of the fabric. After the clamping plate positions both sides of the fabric, it effectively prevents deviation during cutting. The threaded rod is rotated, and under the limit of the sliding rod, the mounting seat slides on the top of the fixed frame, and the socket moves synchronously, so that the ring enters the inside of the socket to provide support force for one end of the unwinding roller. When the fabric is subjected to the pulling force of the winding roller, the ball will rub against the unwinding roller, so that the winding roller can rotate synchronously, the fabric is discharged in an orderly manner, and one end of the fabric is pulled to the bottom of the cloth pressing roller, the bottom of the adjusting roller and the top of the deviation correcting roller. , and finally wrap it around the outside of the winding roller, which rotates through the winding roller, and then the fabric is transmitted in an orderly manner, generating friction with the blade, and the fabric is cut.
