Problems solved by technology

This solution can realize the function of trimming while processing, and in order to avoid interference between the cutting knife and the presser foot, a press ring with a circular upper sipe is used, but the use of a circular upper sip leads to cutting. The fabric near the foot of the cutter is in a loose state, which will cause wrinkles in the fabric during the cutting process of the cutter, which not only affects the accuracy of fabric cutting, but also affects the aesthetics of the product

Abstract

The invention provides a cutter device for a sewing machine and belongs to the technical field of machinery. The problem of low cloth cutting precision of an existing cutter device is solved. The cutter device for the sewing machine comprises a lifting rack, a cutter, a pressure foot and a lower cutter plate which can rotate, a rotation rack which can rotate along with the lower cutter plate synchronously is arranged on the lifting rack, and the pressure foot and the cutter are arranged on the lower portion of the rotation rack; the pressure foot comprises a first press plate and a second press plate, a strip-shaped gap for the lower portion of the cutter to penetrate through is formed between the first press plate and the second press plate, and the width of the strip-shaped gap is slightly larger than the thickness of the cutter. The cutter device for the sewing machine is reasonable in structure and high in cutting precision.

Description

Technical field [0001] The invention belongs to the technical field of machinery, and relates to a cutter device, particularly a cutter device of a sewing machine. Background technique [0002] Existing numerical control sewing processing equipment, including sewing template roller clamping drive device, X, Y motion device, electric control box and control system, sewing device, frame and machine, etc.; after the completion of the sewing process, it needs to be adjusted Trimming the edges of the fabric to be sewn, if the CNC sewing and processing equipment completes the trimming of the fabric while processing, it will greatly improve work efficiency. For this reason, people design a cutting device for trimming on the sewing machine. [0003] For example, a Chinese patented cutting knife device for a smart sewing machine [Announcement No. CN205974991U] is characterized in that it includes the upper part and the lower part of the worktable; the upper part of the worktable is connect...
