Embodiment Construction

[0009] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0010] Such as figure 1 Shown, this sewing machine comprises machine head 1, presser foot bar guide sleeve 3, cutter bar 4, cutter drive bar 5 and cutter seat 6. The presser foot rod guide sleeve 3, the cutter rod 4 and the cutter drive rod 5 are arranged in sequence along the longitudinal direction of the machine head 1 from the action end to the end.

[0011] There is an installation chamber in the machine head 1, and the presser rod guide sleeve 3 is located in the installation chamber of the machine head 1, the presser foot rod guide sleeve 3 is vertically arranged, and the lower end of the presser foot rod guide sleeve 3 is fixedly connected with the machine head 1. A presser bar 2 is worn inside the presser bar guid...

Abstract

The invention provides a sewing machine, and belongs to the technical field of sewing. The sewing machine solves the problem that the heating and clamping phenomena are likely to happen on a guiding component between a cutter holder and a machine head of an existing sewing machine. The sewing machine comprises a machine head and a cutter holder located on the lower side of the machine head. A presser bar guiding sleeve is fixedly arranged inside the machine head. A guiding base arranged on the guiding sleeve in a sleeving mode is arranged inside the machine head. A cutter bar is fixedly arranged on the cutter holder. The upper end of the cutter bar penetrates into the machine head and is fixedly connected with the guiding base. According to the sewing machine, it is ensured that the cutter bar does not rotate and a cutter fixed to the cutter holder is operated stably. Lubricating oil for lubricating a needle bar, a presser bar and other components is contained inside the machine head of the sewing machine, obviously, the lubricating oil can also lubricate and cool a gap between the guiding base and the presser bar guiding sleeve and a gap between the cutter bar and the machine head in an auxiliary mode, the sewing machine can be operated at high speed for a long time, and it is still ensured that the guiding base and the cutter bar are operated stably. The advantage that the structure of the sewing machine is simplified is achieved due to the fact that the guiding base achieves guiding through the presser bar guiding sleeve.

Description

technical field [0001] The invention belongs to the technical field of sewing, in particular to a sewing machine. Background technique [0002] In the process of garment processing and home textile processing, the fabric needs to be trimmed first, and then flat-sewn. Along with social development, someone has proposed the sewing machine with trimming function, as the sewing machine (application publication number: CN103710889A) of Chinese patent document record and the applicant proposes sewing machine (application publication number: CN104562466A). The above two kinds of sewing machines are connected between the cutter base and the machine head through guide rails. Due to the high speed of the sewing machine, that is, the cutter base reciprocates quickly along the guide rails, and it is very easy to cause the parts to heat up and get stuck, and even lead to the scrapping of the guide structure. Therefore, there are problems affecting production efficiency and low service l...
