Description

Technical Field

[0001] This invention relates to a quilted noise-reducing curtain sewing structure and process. Background Technology

[0002] Curtains are quite common, mainly installed at windows, serving to block light, provide sun protection, and protect privacy—these are the basic functions of existing curtains. However, most existing curtains lack noise reduction capabilities. Outside noise is primarily blocked by glass or other sound insulation materials, reducing the decibel level, but this effect is limited. Therefore, our company has designed a curtain with noise reduction capabilities. This is achieved by incorporating noise-absorbing materials inside the curtain. However, existing sewing machines struggle to sew such curtains. Furthermore, curtain fabrics are generally quite large, making edge alignment and finishing extremely inconvenient. Existing sewing equipment is also difficult for a single person to operate, easily leading to misaligned stitches and slow sewing speeds. Therefore, designing a curtain sewing machine has become essential. Summary of the Invention

[0042] Furthermore, the sewing process for the quilted noise-reducing curtain structure includes the following steps:

[0043] 1) Lay the sun-protective fabric, quilted fabric, and decorative fabric on the tabletop in sequence;

[0044] 2) A negative pressure is created inside the tabletop using a negative pressure device to adhere the curtain fabric to the tabletop. The fabric is then smoothed to ensure that both edges of the fabric are flush.

[0045] 3) Continue to adjust the fabric, moving the part of the fabric that needs to be sewn to the edge of the sewing table and placing it on the sewing table.

[0046] 4) Start the walking motor, and the sewing machine body will work synchronously. The sewing machine body will move along the edge of the table panel and sew the curtain fabric while moving until the curtain fabric on this side of the table panel is sewn.

[0047] 5) Once one side of the curtain fabric is sewn, the thread is automatically cut off, and the movable sewing mechanism returns to its original position.

[0049] The quilted noise-reducing curtain of the present invention comprises three parts: sun-protective fabric 33, quilted fabric 34, and decorative fabric 35. The completed curtain has good sun protection and noise reduction effects, making it more functional than traditional curtains and suitable for more occasions.

[0050] The curtains of this invention are sewn with transparent silk thread, resulting in no visible stitches after the curtains are sewn, creating a seamless effect and enhancing the curtains' usability.

[0051] The sewing machine body of the present invention operates synchronously with the forward or reverse rotation of the walking motor, and can also be controlled independently.

[0052] The sewing machine body of this invention is obtained directly from procurement, so it will not be described in detail.

[0053] When using this invention, if it is necessary to rotate the table panel, simply rotate the table panel. The positioning pin is squeezed out of the positioning hole. When the positioning pin coincides with the position of the next positioning hole, under the action of the spring, the positioning pin is inserted into the positioning hole again, thereby repositioning the table panel.

[0054] When it is necessary to iron or dampen the curtain fabric, turn on the steam. The steam will be ejected through the air pipe and through the hole, thus achieving the effect of dampening or ironing.

[0055] During operation, the curtain fabric is fixed by the suction of the ceiling panel, which facilitates subsequent operations on the curtain fabric.

[0056] When you need to cut the curtain fabric to the required length, you can refer to or observe the length markings on the cutting board to make the cutting process easier.

[0057] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
