Plastic woven fabric sewing machine

A plastic woven fabric sewing machine, comprising at least one stitching device at one end of a tabletop of a low-temperature worktable;

• the tabletop of the worktable being provided with at least one thread knot shaping recess;
• the stitching device including a stitching needle cylinder, the stitching needle cylinder having a cylinder body mounted to a support frame that can be reciprocated up and down, one end of the stitching needle cylinder being formed with a needle portion relative to the thread knot shaping recess, the needle portion having a tip that is moved close to and away from the tabletop of the worktable through the cylinder body of the stitching needle cylinder for the tip to be inserted in and out of the thread knot shaping recess, the tip being formed with a needle hole communicating with one end of a chamber inside the cylinder body, another end of the chamber being provided with a material inlet, the material inlet being configured to receive a pressurized molten plastic material from a material receiving tube;
• wherein when in use, two overlapped fabrics are placed on the tabletop of the worktable to be stitched, the tip of the needle portion of the stitching needle cylinder penetrates through the two fabrics to enter the thread knot shaping recess, the plastic material in the chamber is injected into the thread knot shaping recess from the needle hole, after the injected plastic material is cooled, it forms a thread knot to buckle the two fabrics, after that, the tip of the needle portion is retracted from the two fabrics to generate a short stitching thread section, the tip of the needle portion is relatively displaced on the two fabrics to complete one stitch of the two fabrics, the two fabrics are stitched together through continuous multiple stitches, and the stitches each have the thread knot to provide an independent buckle effect so that the stitches do not affect each other.
