[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-5 The utility model provides a cloth strip clamping device for a computer flat-bed sewing machine, comprising a workbench 1 and a sewing machine body 2, wherein the sewing machine body 2 is arranged on the top of the workbench 1, and two moving components 3 are arranged on the front and rear sides of the workbench 1, wherein the two moving components 3 are arranged one in front and one in the rear, and two fixed brackets 4 are arranged on the two moving components 3, wherein the two fixed brackets 4 are arranged one on the left and one on the right, and a clamping structure 5 is arranged on the fixed brackets 4.

[0018] Specifically, the moving assembly 3 includes a support box 31, a bidirectional screw 32, a protection box 33, a motor 34, a limit rod 35 and two moving seats 36. The support box 31 is arranged on the front side of the workbench 1, and an opening is opened on the top of the support box 31. The bidirectional screw 32 is rotatably connected to the left and right sides of the support box 31 respectively. The protection box 33 is arranged on the left side outside the support box 31. The motor 34 is arranged in the protection box 33, and one end of the bidirectional screw 32 is connected to the driving end of the motor 34. The limit rod 35 is arranged between the left and right sides in the protection box 33. The limit rod 35 is located below the bidirectional screw 32. The two moving seats 36 are movably connected to the left and right sides of the bidirectional screw 32 and the limit rod 35 respectively, and the bracket is arranged on the moving seat 36.

[0019] Specifically, the clamping structure 5 includes two cylinders 51 and a clamping plate 52 . The two cylinders 51 are arranged on the top of the fixed bracket 4 , and the driving ends of the two cylinders 51 moveably pass through the top of the fixed bracket 4 . The clamping plate 52 is arranged on the driving ends of the two cylinders 51 .

[0020] Specifically, a rubber pad 53 is disposed at the bottom of the clamping plate 52 , and the rubber pad 53 increases the friction between the clamping plate 52 and the cloth strip.

[0021] Working principle: When clamping the cloth strip, turn on the motor 34, and the driving end of the motor 34 will drive the bidirectional screw 32 to rotate.
