Description

Technical Field

[0001] The present application relates to the technical field of sewing machine auxiliary devices, and in particular to an auxiliary device for processing clothing ribbons and a method of using the same. Background Art

[0002] In various existing casual clothes, a decorative strip is generally sewn on the edge of the clothes. The decoration is arranged around the edge of the clothes. The decorative strip can highlight the edge position of the clothes and can have a color adjustment effect, making the color of the clothes more vivid. This setting is very common on some thicker clothes. When sewing the decorative strip on the edge of the clothes, a sewing machine is required to sew. When sewing the decorative strip, it is generally sewn between two layers of cloth, and the decorative strip part will extend out of the two layers of cloth.

[0003] The prior art, such as a sewing machine disclosed in a Chinese patent with the authorization announcement number CN102051769B, is appropriately equipped with a solenoid for lifting the presser foot. The sewing machine has: a fabric presser foot; a presser foot bar; and a presser foot lifting mechanism. In the sewing machine, the solenoid is arranged in the arm of the sewing machine frame. The sewing machine has a presser foot spring, which presses the fabric presser foot downward via the presser foot bar. The presser foot lifting mechanism has a link pair consisting of two link bodies rotatably connected to each other in the middle of the power transmission path from the solenoid to the presser foot bar. One link body of the link pair is rotatably supported by an axis relative to the sewing machine frame. Under the action of the elastic force of the presser foot spring, the two link bodies are in a bent state. When the fabric presser foot is raised from the lower position pressing the sewn object to the retreat position by the solenoid, the link pair changes its posture from the bent state to the extended state.

[0004] Another example is a sewing machine disclosed in a Chinese patent with the authorization announcement number CN101748566B, which can move the middle presser foot up and down without damaging the fabric. The sewing machine has: a spindle angle detection unit, which detects the angle of the spindle that is driven by the sewing machine motor to move the needle up and down; an middle presser foot, which prevents the sewn object from floating up during sewing; an middle presser foot up and down movement mechanism, which moves the middle presser foot up and down synchronously with the sewing needle; an middle presser foot height adjustment mechanism, which adjusts the height of the middle presser foot by the middle presser foot motor; and an middle presser foot height control unit, which controls the middle presser foot motor. The middle presser foot height control unit performs height variable control within a specified rotation range in which the middle presser foot descends, outputs a driving torque that is balanced with the external torque, and tracks and controls the middle presser foot motor after the height variable control to maintain the final output shaft angle of the height variable control range.

[0005] Another example is a sewing machine disclosed in a Chinese patent with the authorization announcement number CN105506867B, which can sew the front placket more efficiently. The sewing machine has: a fabric presser foot, which holds the main fabric and the front placket fabric; a fabric moving mechanism, which allows the fabric presser foot to move arbitrarily along the plane on which the main fabric is placed; a sewing needle up and down moving mechanism, which drops the needle relative to the main fabric and the front placket fabric held by the fabric presser foot; a cutting knife mechanism, which forms a slit in a fixed direction on the main fabric and the front placket fabric held by the fabric presser foot; and a first folding mechanism, which folds the front placket fabric back along the stitches formed near the slit forming position formed by the cutting knife mechanism.

[0006] As described above, the prior art is that the sewing machine mainly uses the presser foot to press and position the cloth, so that the needle can sew the cloth. However, if the two layers of cloth are directly sewn together with the decorative strip, because the decorative strip partially extends between the two layers of cloth, the part of the decorative strip extending between the two layers of cloth is in a place that the staff cannot see. Therefore, if the two layers of cloth are sewn together with the decorative strip, it is easy to deviate during sewing, resulting in different sizes of the parts of the decorative strip extending out of the two layers of cloth, and even the decorative strip is completely sewn between the two layers of cloth. Therefore, when sewing the decorative strip, it is necessary to first sew the decorative strip on one of the layers of cloth, and make one side of the decorative strip cooperate with the layer of cloth, and then sew the other layer of cloth on the other side of the decorative strip, resulting in low sewing efficiency of the decorative strip, so it needs to be improved.
