Description

A positioning device of a sewing machine for an air conditioner filter element of a motor vehicle

technical field

The invention relates to the technical field of production and processing of air filter elements, in particular to a positioning device of a sewing machine for an air conditioner filter element of an electric vehicle.

Background technique

A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material; the sewing machine can sew cotton, linen, silk, wool , man-made fibers and other fabrics and leather, plastic, paper and other products, the stitches sewn are neat and beautiful, flat and firm, fast sewing speed, easy to use, and derived from hand-pushing computer embroidery and other art forms, there are many classification methods of sewing machines , It is more common to distinguish according to stitches and uses. The stitches of sewing machines can be classified into two types: lock stitches and chain stitches; lock stitches are the most common, which consists of two stitches, like twisting ropes. Intertwined with each other, the interweaving point is in the middle of the sewing material. From the cross-section of the stitch, the two stitches are like two locks locked with each other, so they are called lock stitches. This stitch is used for small shrinkage. Sewing materials such as cotton, wool fabric or leather, the front and back sides have the same shape, like a dotted line, the stitches are densely distributed, and the sewing fastness is generally higher than manual sewing. Commonly used are single-thread chain, double-thread chain and three-thread overlock stitches. This stitch is characterized by elastic stitches, which can expand and contract with the sewing material without breaking the stitches. It is suitable for thread Garments made of elastic fabrics or products and blanks that are easily loosened by overlocking. In addition, sewing machines can be divided into household, industrial, and service industry machines according to their uses, and can also be divided into hand-crank sewing machines and pedal sewing machines according to the driving form. , Electric sewing machine, in the process of producing air filter element, it is necessary to use industrial sewing machine to sew the multi-layer filter element together, and the air filter element is installed in the air compressor of the locomotive to filter the dust in the air. When the air filter element is used, it is necessary to stack multiple layers of filter cotton and sew it with a flat machine. The edges of the stitched filter cotton have uneven burrs, which are not only different in size, but also very unsightly, and are easy to install and disassemble. The appearance of hook sleeves is inconvenient for workers to operate. In order to avoid uneven edges, the edge-aligned production process is often used, that is, the edge of the filter cotton is trimmed with a cutting device, which increases the operation steps and production costs. For these situations, in order to avoid In view of the above technical problems, it is indeed necessary to provide a positioning device for a sewing machine for an air conditioner filter element of a motor vehicle to overcome the defects in the prior art.
