Description

Technical Field

[0001] The utility model relates to the field of quilting machines, in particular to a needle-discharging pressure plate mechanism. Background Art

[0002] The shuttleless multi-needle quilting machine is a highly efficient sewing device widely used in a variety of production fields, including clothing, bedding, and textiles. The main principle of the shuttleless multi-needle quilting machine is to pass multiple needles simultaneously on the surface of the fabric, penetrate and wind the long thread, and remove the needle and thread from the suture slit, forming a high-strength, strong flat or convex seam. The use of multiple needles allows for a smaller stitch length, more beautiful suture results, and greatly improves production efficiency, saving production time and costs. The pressure plate is a key component of the shuttleless multi-needle quilting machine. Its main function is to press down the sewing material to prevent it from moving or deforming during the needle penetration and suture process, thereby ensuring the smoothness and beauty of the suture lines.

[0003] The existing pressure relief plates are not easy to install and disassemble. Generally, the pressure relief plates are fixed and installed by bolts. When installing and disassembling them, tools are needed to disassemble and assemble them. The disassembly and assembly process is relatively cumbersome, which increases the workload and reduces the work efficiency. It is not convenient to use and the height cannot be adjusted. Generally, the pressure relief plates are fixed to the vertical arms. During use, if the height of the pressure relief plates is too low, the pressure of the pressure relief plates on the fabric will be too great, which may easily cause damage to the pressure relief plates and reduce their service life. If the height is too high, the pressure on the fabric will be too small, affecting the stability of the fabric, thereby affecting the flatness and beauty of the stitches. In order to solve the above problems, we propose a pressure relief plate mechanism with a needle. Utility Model Content
