Description
Technical Field
The invention relates to the technical field of sewing machine facial threads, in particular to a facial thread cutting mechanism of a sewing machine.
Background
The upper thread is used by penetrating through the needle eye of the needle, and moves up and down with the needle at high speed when sewing cloth. In sewing, in order to prevent the upper thread from being separated from the needle eye of the machine needle, the current method is to reserve a longer seam starting thread head (namely, the length of the upper thread passing through the needle eye is reserved to be longer); however, in this method, the length of the seam starting thread end is reserved to be longer, so that the thread end remained on the fabric after the fabric is sewn is longer, and the seam starting thread end of the upper thread and the seam starting thread end of the lower thread are wound together to form a bird nest structure, which affects the quality of the product. In order to reduce the influence of the thread end lifting process of the upper thread, the thread end remained on the cloth needs to be manually cut off, so that the operation is more complicated and the efficiency is lower.
In order to solve the above problems, chinese patent document discloses a thread trimming mechanism of a sewing machine [ application publication No. CN104652054A ], including a stationary knife fixed on the lower side of a needle plate and a moving knife hinged on the lower side of the needle plate, the moving knife includes a hinge portion and a thread catching portion for catching a needle thread, the hinge portion is connected with a driving mechanism capable of rotating the moving knife around a hinge point and making a thread trimming motion with the stationary knife, an elastic clip is provided between the stationary knife and a needle hole of the needle plate, the elastic clip includes a clamping portion and a connecting portion connected with the needle plate, the clamping portion is in a long-blade shape and a gap is provided between the clamping portion and the needle plate, when the moving knife rotates around the hinge point, the clamping portion can be elastically deformed towards the needle plate direction under the action of the thread catching portion, and the clamping portion is tightly abutted against the thread catching portion under the action of its own elastic force. The upper thread is cut off through fixed stationary knife and the sword that moves that articulates at the faller downside in this patent, because move the sword and realize the crochet hook and cut the line through the pivoted mode, consequently move the area that the sword rotated the cover and all need reserve and supply to move the sword and rotate, also can't set up other structures in the pinhole below peripheral position of faller, consequently, lead to distributing between mechanism in the sewing machine more dispersedly, simultaneously in order to realize the cut line, the fixed position of stationary knife is located and moves the sword tip pivoted route and just can realize the cut line, the position that the stationary knife moved the sword relatively also more dispersedly, the structure is not compact.
