Description

Technical Field

[0001] The utility model relates to the technical field of sanding devices, in particular to a sanding device for sewing thread production. Background Art

[0002] There are many types of sewing threads. Especially with the development of chemical fiber production technology, polyester sewing thread and nylon sewing thread account for an increasingly higher proportion of sewing threads. Polyester sewing thread and nylon sewing thread have high strength and good wear resistance, and are increasingly replacing cotton sewing thread. The raw material threads of polyester sewing thread and nylon sewing thread are relatively smooth, so the surface of the produced polyester sewing thread and nylon sewing thread is also relatively smooth, which affects the structural stability of the product. Therefore, when producing sewing thread, a grinding device is required to grind the sewing thread;

[0003] A Chinese patent with prior art authorization announcement number CN211142335U discloses a sewing thread air-blowing sanding device, which passes the silk thread through a grinding plate and winds the end of the silk thread around the outer ring surface of a take-up roller, then closes the upper box, controls the operation of the compressor with a single-chip microcomputer, and opens the corresponding solenoid valve. The airflow movement generated by the compressor forces the silk thread to contact the upper surface of the grinding plate, and the rotation of the motor drives the rotation of the take-up roller, thereby sanding the silk thread on the grinding plate. The air blowing can ensure that the wire body is evenly stressed on the grinding plate to ensure that the degree of sanding of the wire body is consistent.

[0004] Although the above patent can grind the sewing thread, it can only grind one side of the sewing thread, and the grinding of the other side needs to be repeated, which greatly wastes time and reduces efficiency. Moreover, although it can ensure that the degree of grinding of the thread body is consistent, it cannot adjust the surface roughness of the sewing thread, which reduces the grinding effect.

[0005] Therefore, the applicant proposed a sanding device for sewing thread production to solve the above problems. Utility Model Content
