[0002] Clothing production refers to the process of making raw materials such as textiles, leather or artificial materials into ready-made clothes, accessories and other products through processes such as cutting, sewing, ironing and inspection. In clothing production, the selection of raw materials is crucial, including fabrics, accessories, etc. The selection of these materials directly affects the quality of the finished product and the wearing experience. Flat-bed sewing machines are needed when producing clothing.

[0003] After searching, the announcement number is CN213772479U, and the name is a utility model of a flat sewing machine, including a frame. Through research and analysis, it is found that although it is convenient to take the sewing fabrics and clothes, it still has the following disadvantages to a certain extent.

[0004] For example, when using it, the staff needs to tighten the cloth by hand, and it does not have the function of conveniently pressing the cloth. Therefore, it is inconvenient for the staff to operate when tightening the cloth for sewing, which reduces the convenience of operation. In addition, the surface of the cloth is prone to wrinkles, and it does not have the function of smoothing the cloth, which causes the surface of the cloth to be uneven, affecting the quality of the cloth after sewing. In order to solve the above technical problems, we have designed a flat sewing machine for clothing production that is easy to operate. Utility Model Content

[0005] The utility model aims to provide a flat sewing machine for clothing production that is easy to operate and has the advantages of being convenient for pressing the fabric and being able to smooth the fabric, thereby solving the problems of being inconvenient for pressing the fabric and being unable to smooth the fabric.

[0009] Preferably, the smoothing assembly includes a moving rod, the bottom end of which passes through the top of the support frame, the bottom end of the moving rod is connected to a U-shaped plate by bolts, the inner cavity of the U-shaped plate is movably connected to a smoothing roller by a bearing, and a connecting spring is provided on the surface of the moving rod.

[0010] Preferably, the top end of the moving rod is connected to a pull plate via bolts, and the top and bottom ends of the connecting spring are welded to the inner wall of the support frame and the top of the U-shaped plate respectively.

[0011] Preferably, the left end of the support frame penetrates into the interior of the transverse plate, a limiting groove for cooperating with the support frame is provided on the left side of the transverse plate, and a supporting leg is connected to the bottom of the transverse plate by bolts.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model cooperates with the L-shaped plate, the two-way threaded rod, the hand wheel, the tension spring, the connecting telescopic rod, the movable plate and the circular plate, and has the advantage of conveniently pressing the cloth. The two-way threaded rod is rotated by turning the hand wheel to move the movable plate, so that the L-shaped plate can be moved to adjust its position. After the adjustment is completed, the L-shaped plate is pulled upward to extend the connecting telescopic rod and the tension spring, and the cloth is stretched and laid flat under the L-shaped plate. The L-shaped plate is loosened to reset the tension spring to press the cloth. When sewing, the staff does not need to stretch the cloth to both sides for sewing, which is convenient for the staff to operate.

[0014] 2. The utility model has the advantage of being able to smooth the cloth by cooperating with an electric telescopic rod, a support frame, a connecting spring, a smoothing roller, a U-shaped plate, a moving rod and a pulling plate. The cloth is placed under the smoothing roller by pulling the pulling plate upwards. After the placement is completed, the pulling plate is released to reset the connecting spring, so that the smoothing roller contacts the cloth and the cloth is pulled forward. At the same time, the electric telescopic rod is shortened to drive the support frame to move backward, thereby smoothing the cloth and improving the flatness of the cloth.
