In the cutting and edge covering integrated sewing machine, the cutter mounting seat is detachably and fixedly connected with a connecting plate perpendicular to the cutting edge, the upper end of the servo-actuated front presser foot is provided with a connecting part vertically arranged, and the connecting part of the servo-actuated front presser foot is detachably and fixedly connected onto the connecting plate through a bolt. The purpose of the arrangement is to facilitate the disassembly or assembly of the servo-actuated front presser foot on the connecting plate; the connecting plate is convenient to disassemble or assemble on the cutter mounting seat, and the use is convenient.

In the above-mentioned cutting and edge-covering integrated sewing machine, the follow-up front presser foot is of an arc-shaped bent sheet-shaped structure, and the follow-up front presser foot has deformation displacement towards the direction of the machine needle presser foot when abutting against the needle plate. The purpose of the arrangement is to provide the acting force for pushing the cloth towards the direction of the needle presser foot when the servo-actuated front presser foot is elastically abutted against the cloth placed on the needle plate, so that the cloth can be conveniently pushed to the lower part of the needle presser foot, and the material can be conveniently discharged and pushed.

In the cutting and edge covering integrated sewing machine, the follow-up front presser foot comprises a connecting part which is curved in an arc shape towards the upper part of the connecting plate to the lower part of the connecting plate to form an elastic body, the elastic body is curved towards the direction of the needle presser foot to form a leaning part, and the lower surface of the leaning part is in leaning fit with the upper surface of the needle plate. Through forming to lean on the portion and the faller elasticity of leaning on the cooperation, the elasticity of presser foot and faller before this follow-up leans on the active area great, and elasticity suppression cloth effect is better, and is more stable with the cloth towards the propulsive effort of eedle presser foot direction.

In the cutting and edge covering integrated sewing machine, the connecting plates are symmetrically provided with the strip-shaped holes which are vertically distributed, and the strip-shaped holes are penetrated with the connecting bolts and are fixedly connected to the cutter mounting seat through the connecting bolts. The purpose of setting like this can be through changing the upper and lower assembly position of connecting plate and cutter mount pad and effectively adjust the elastic force of presser foot before the follow-up, adjust convenient to use.

Compared with the prior art, the cutting and edge covering integrated flat sewing machine has the advantages that: the structure sets up rationally, simple, and presser foot sets up alone before the servo-actuated of eedle presser foot and cutting blade, when satisfying the eedle that prevents on the eedle pole and beating, prevent to move the cutting blade and appear fold phenomenon when the cutting, still has the flexibility of higher sewing turn, and sewing turn resistance is little, can once only accomplish the less work of making up of sewing turn angle, convenient to use, reduction in production cost.
