Problems solved by technology

In this technical solution, the cutter is arranged under the platen, and the cutter and the cutter groove use the same rotating motor. Although the problem of synchronous rotation between the cutter groove and the cutter is solved, the manufacturing cost is not low, and the structure is relatively Complicated, but also brings troublesome assembly

Embodiment 1

[0030] Such as figure 1 , 2 As shown in and 3, the automatic cloth cutting mechanism is installed on the sewing equipment. The sewing equipment is provided with a controller, a platen 3 and a pressing assembly located above the platen 3. The pressing assembly includes a pressing plate 2 and a driving pressing assembly. Plate 2 is the driving part 2 that presses the cloth. The driving part 2 is connected with the controller. The driving part 2 is the pressing cylinder 1. Of course, besides the pressing cylinder 1, the driving part 2 can also be an electromagnet or other linear drive mechanism. This automatic cloth cutting mechanism is positioned at platen 3 belows, comprises cloth cutting motor seat 5, rotating motor mount 14, driver one and has the cutting knife groove disc 4 of strip through hole 41.

[0031] The platen 3 is provided with a circular mounting hole 31 matching the cutter groove disc 4, the cutter groove disc 4 is located in the circular mounting hole 31, and t...

Embodiment 2

[0041] Such as Figure 5 As shown, the difference between this embodiment and the first embodiment is that the cutter assembly includes a straight cutter 28, a cutter shaft 26, a connecting rod 24 and an eccentric wheel 22 fixedly mounted on the output shaft of the cloth cutting motor. The upper end of the cloth cutting motor seat has a guide groove 29, the lower end of the cutter shaft 26 is fixedly connected with a screw 25 and is located in the cloth cutting motor seat, the upper end of the connecting rod 24 is sleeved on the screw 25 and rotates around the screw 25, the connecting rod 24 The lower end is set on the eccentric wheel 22 through the needle roller bearing 23 and rotates around the eccentric wheel 22. The upper end of the cutter shaft 26 protrudes above the cutter motor seat through the guide groove 29, and the straight knife cutter 28 passes through the cutter seat 27. Fixedly connected on the upper end of the cutter shaft 26, the straight knife cutter 28 is po...

Abstract

The invention provides an automatic cloth cutting mechanism and belongs to the technical field of sewing equipment. The problems that an existing cloth cutting mechanism is complex in structure and high in cost are solved. The automatic cloth cutting mechanism comprises a cloth cutting motor seat and a cutter groove disc, a cutter assembly with a cutter and a cloth cutting motor for driving the cutter assembly to work are arranged on the cloth cutting motor seat, and a first driving part and a rotary motor mounting seat connected with the first driving part are further included, and a cutter rotary motor is arranged on the rotary motor mounting seat. The cutter groove disc is connected with the cloth cutting motor seat through a transmission structure, an output shaft of the cutter rotary motor is fixedly connected with the cloth cutting motor seat and drives the cloth cutting motor seat and the cutter groove disc to rotate, and the first driving part drives the rotary motor mounting seat and the cloth cutting motor mounting seat to vertically move. The automatic cloth cutting mechanism has the advantages of achieving free curve cloth cutting and being simple in structure, good in stability and low in cost.

Description

technical field [0001] The invention belongs to the technical field of sewing equipment and relates to an automatic cloth cutting mechanism. Background technique [0002] Sewing is an important processing procedure for garments and hats. During the sewing process, multiple cuttings are carried out according to the needs. Not only can it be cut in a straight line, but because garments generally have arcs or bent parts with angles, it is important for cutting cloth The organization has put forward higher requirements, requiring it to also perform multi-angle cutting such as arcs or folded lines. [0003] In order to solve the above problems, a cloth cutting mechanism with a rotatable cutter came into being. Generally, three motors are provided, namely: the drive motor for the cutter to move up and down (or the cutter blade to rotate), the cutter rotating motor, and the cutter groove rotating motor. Since the cutter is installed on the platen, and at the same time, the cutter ...
