Abstract

The invention discloses a composite thread cutting device, which comprises a vertical plate, a first air suction channel and a second air suction channel are respectively arranged on both sides of the vertical plate, a rotating shaft is arranged under the vertical plate, and the rotating shaft One end is connected with the first driving motor, and the other end is connected with the chopping knife, and the vertical plate above the said chopping knife is provided with a grid block; one side of the vertical plate is provided with a transmission rod, and one end of the transmission rod is connected with a The second drive motor is hinged with a movable air suction knife at the other end, the movable air suction knife is hinged on the vertical plate, and the front end of the vertical plate is also fixedly provided with a fixed air suction knife matched with the movable air suction knife. It can meet the cutting requirements of various cutting knives at the same time, with high cutting precision and can meet the requirements of multiple blade suction at the same time.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a compound thread cutting device. Background technique [0002] Existing computerized overlock sewing machines all have thread cutter device, and this thread cutter device is positioned at the rear of needle plate. The device drives the thread cutter through the electromagnet to cut off the thread braids at the front end of the sewing material and the thread braids at the rear end of the sewing material. When the operator feeds the cloth straight forward, it can well cut off the front and back braids of the sewing material. However, due to the operating habits of the sewing worker, the sewing material is pulled back when the rear end of the sewing material has not passed the thread cutter when feeding, and when the cloth is fed in an oblique direction, it is easy for the thread cutter to fail to cut the rear end of the sewing material. In this case, the work efficiency ...
