Embodiment 1

[0028] Such as Figure 1 to Figure 4 As shown, the trimming, hemming and sewing three-in-one sewing machine includes a machine head 1, a bottom plate 2, an edge curler 3, a cutter seat 4, a blanking joint 5 and a transmission assembly.

[0029] The action end of machine head 1 is worn with machine needle bar 6 and presser foot bar 7, and machine needle bar 6 and presser foot bar 7 are vertically arranged. The transmission assembly is located in the machine head 1, and the transmission assembly includes components such as a transmission shaft and a cam, and the transmission shaft is connected with the motor. The machine needle bar 6 and the presser foot bar 7 are all connected with the transmission assembly, that is, the rotation of the motor main shaft drives the machine needle bar 6 and the presser foot bar 7 to reciprocate up and down. The lower end of the machine needle bar 6 is fixed with an organic needle 8, and the lower end of the presser foot bar 7 is connected with a...

Embodiment 2

[0042] The structure and principle of this embodiment are basically the same as that of Embodiment 1, except that the lower end of the transmission rod is connected with the cutter seat 4 by a clutch, and a spring 18 is set on the transmission rod, and the spring 18 makes the clutch in During the separated state, the knife plate 15c is separated from the needle plate 10, and the trimming process is cancelled. Only transmission rod moves up and down during this state, parts such as cutter seat 4 and cutter 15 do not move, and then reduce the load of motor.

Abstract

The invention provides an edge cutting, edge binding and sewing three-in-one sewing machine and belongs to the field of sewing technology. The edge cutting, edge binding and sewing three-in-one sewing machine solves the problems of structural instability of the cutter module and position unclearness of the discharging port in an existing sewing machine. The edge cutting, edge binding and sewing three-in-one sewing machine comprises a machine head, a bottom plate, a beader and a cutter seat. A machine needle bar and a pressing foot bar which are connected with a transmission module penetrates the acting end of the machine head; the lower end of the pressing foot bar is provided with a pressing foot; a needle plate is arranged under the pressing foot and fixed onto the bottom plate; the upper edge of one side of the needle plate is provided with a static cutting blade; the cutter seat is connected with the acting end of the machine head through a guide structure; the cutter seat is connected with the transmission module; the cutter seat is fixedly provided with a cutter; the cutter is provided with a movable cutting blade matched in pair with the static cutting blade, and the movable cutting blade is inclined relative to the bottom plate. According to the edge cutting, edge binding and sewing three-in-one sewing machine, the static cutting blade is made of tungsten steel and has the advantage of being long in service life; a cutter plate is replaceable to ensure that the movable cutting blade is sharp and further to ensure action effectiveness and regularity of edge cutting.

Description

technical field [0001] The invention belongs to the technical field of sewing, and relates to a sewing device, in particular to a three-in-one sewing machine for trimming, wrapping and sewing. Background technique [0002] In the process of garment processing and home textile processing, it is necessary to cut the edge first, then wrap the edge, and finally sew. In traditional processing, the above three processes are carried out separately. [0003] With the development of society, traditional processing methods are no longer suitable for the production requirements of modern enterprises. Therefore, once someone has proposed a kind of sewing machine application publication number that has trimming, hemming, sewing three-in-one process: CN103710889A) comprises machine head and base plate, is provided with organic needle and presser foot on the action end of machine head, opposite on the base plate. A needle plate is arranged under the machine needle, and a cloth feeding do...
