Technical Field

The invention relates to the field of sewing, in particular to a hemming positioner for hemming sewing, which is used for hemming sewing and strictly controlling the hemming amount.

Background

China is a large three billion population country, the largest consumer and producer of garments worldwide. In recent years, the garment industry in China has great development, the development of the garment industry greatly promotes the development of the national economy, the total value of textile garments in 2005 accounts for about one tenth of the total value of the whole country, and the garment industry continuously exports for five years to earn money, so that the garment industry always makes great contribution to earning money for the export of China. Meanwhile, China has become the biggest garment production and processing base all over the world, and every three garments all over the world are produced in China.

At present hem sewing operation can adopt manual hem, or simple fixture block location hem sewing, but the operation is slow, and the hem volume is unstable, and the quality receives the influence of workman's proficiency, or adopts professional equipment, and continuous hem production, but the cost is higher, and when needs hem surplus change comparatively complicated, and equipment specificity is strong, is unfavorable for extensively using.

Disclosure of Invention

The invention aims to solve the technical problem of providing a flanging positioner which has a simple structure, is simple and convenient to operate and low in cost, can be suitable for different materials and different flanging margins, and can enable the flanging sewing quality to be free from the influence of the proficiency of workers after the flanging positioner is used.

In order to solve the technical problems, the invention adopts the following technical scheme: the positioning device comprises a cushion block main body and a guide block arranged in parallel with the cushion block main body, wherein one surface, close to the cushion block main body, of the guide block is an upward inclined plane with an arc shape, the upper surface of the guide block is connected with a clamping plate, the arc-shaped surface of the guide block is provided with a groove, one side of the guide block is also provided with a turnover fork, and the cushion block main body and the guide block are both arranged on the working plane of the sewing machine.

Preferably, the turnover fork is installed on a back-and-forth movement device which is parallel to the bottom surface of the guide block groove.

Preferably, in order to ensure that the cloth can be pressed when the turnover fork is turned, the turnover fork is an asymmetric two-strand fork, one of the two-strand fork is also in a diamond shape in the shape of a rotating shaft, and the cloth is pressed while the turnover fork is rotated and turned.

Preferably, the clamping plate is detachably connected with the guide block so as to be suitable for the requirements of curling edges with different margins and achieve wider applicability.

Preferably, the clamping plate is detachably connected with the guide block through a bolt.

Preferably, the pad body is made of a stainless steel material.

Preferably, the guide block is made of a stainless steel material.

Preferably, the detent plate is made of stainless steel material.

Preferably, the flipper fork is made of a stainless steel material.

Preferably, the back and forth movement means is a linear motor.

Has the advantages that: the invention has simple and convenient operation, rapidness and low cost, can be suitable for the flanging positioners with different materials and different flanging margins, can ensure that the flanging sewing quality can eliminate the influence of the proficiency of workers after the flanging positioners are used, and has wide application range.
