Abstract

The invention relates to garment machinery, in particular to a thread cutting device of a sewing machine. The thread cutting device of the sewing machine comprises scissors; and the scissors comprisea first blade and a second blade. Different from the prior art, the scissors can extend from a position far away from a needle position or a to-be-cut position to cut off a thread end, and can retractto the position far away from a needle or the to-be-cut position after cutting off the thread end. Compared with the prior art, the thread cutting device disclosed by the invention can be conveniently arranged at the position far away from the needle or arranged at the to-be-cut position according to customer demands; and a push mechanism and a thread cutting mechanism are designed as a whole, sothat the space is saved, the sight is not blocked and normal sewing is not affected. The cut thread end is shorter and does not need to be trimmed for the second time. The thread cutting effect of automation equipment can be optimized, the equipment efficiency is improved and market promotion is facilitated.

Description

technical field [0001] The invention relates to clothing machinery, in particular to a sewing machine thread trimmer. Background technique [0002] At present, the thread trimmers on the market are generally fixed near the needle of the sewing machine, occupying a certain space, blocking the line of sight, and affecting normal sewing, and because they are fixed, the scissors cannot be very close to the end of the thread, resulting in the end of the thread after thread trimming. Long, need a second pruning. Contents of the invention [0003] The invention discloses a novel sewing machine thread trimming device to overcome the deficiencies of the prior art. The technical solution adopted is: [0004] This sewing machine thread trimming device includes scissors, the scissors include a first blade and a second blade, different from the prior art, the scissors can extend from a position away from the needle position or a position to be trimmed to cut the thread end, After cut...
