[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material, so that one or more layers of sewing materials are interwoven or sewn together. The sewing machine can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, and products such as leather, plastic, and paper. The stitches are neat, beautiful, flat, and firm. The sewing speed is fast and the use is easy. It has also spawned art forms such as hand-push embroidery and computer embroidery.

[0003] In order to make the sewing machine more beautiful and practical during its production process, the parts of the sewing machine need to be polished. However, the structure of the polishing device of existing sewing machine accessories is often too simple, and it is troublesome to adjust the tightness of the polishing cloth. It is necessary to manually stop the polishing device and shorten the length of the polishing cloth, which is inconvenient to use. Utility Model Content

[0004] The utility model aims to provide a sewing machine accessory polishing device to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sewing machine accessory finishing device, comprising a bracket, an adjusting frame, a bidirectional screw, a protection box, a motor, two limit rods, two movable seats, two support rollers and two finishing cloths, the adjusting frame is arranged at the bottom inner part of the bracket, the bidirectional screw is rotatably connected to the top and bottom of the adjusting frame respectively, the protection box is arranged at the top outer part of the adjusting frame, the motor is arranged in the protection box, and the driving end of the motor is connected to the top of the bidirectional screw, two limit rods are arranged between the top and the bottom inner part of the adjusting frame, the two movable seats are movably connected to the upper and lower sides of the bidirectional screw and the two limit rods respectively, the two groups of support rollers are respectively arranged on the two movable seats, and two finishing cloths are movably connected between the two groups of support rollers.

[0006] Preferably, two connecting seats are arranged on the left and right sides outside the bracket, and two cylinders are arranged at the bottom of the two connecting seats.

[0007] Preferably, the screw rod and the adjusting frame are connected via a bearing, an inner ring of the bearing and the screw rod are interference fit, and an outer ring of the bearing and the adjusting frame are fixedly connected.

[0008] Preferably, the bracket is a rectangular frame open front and back, and the adjustment frame is a rectangular frame open left and right.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model can drive the two supporting rollers to move in a straight line toward or away from each other through the bidirectional screw, so as to accurately adjust the distance between the two supporting rollers, and then accurately adjust the tensioning force of the finishing cloth, and the operation is convenient, and the bidirectional screw can support finishing cloths of different lengths, so as to adapt to sewing machine accessories of different sizes. Two groups of supporting rollers and two finishing cloths are arranged on the left and right sides of the movable seat. The two finishing cloths can finish two sewing machine accessories at the same time, which greatly improves the finishing efficiency of the sewing machine accessories. At the same time, the entire device can be driven to rise and fall through the setting of the cylinder. The staff only needs to fix the sewing machine accessories, and the finishing cloth can automatically finish the sewing machine accessories, which greatly reduces the labor intensity of the staff. BRIEF DESCRIPTION OF THE DRAWINGS
