Guide folding die for high speed sewing machine

Abstract

The invention relates to a guide folding die for a high speed sewing machine. The guide folding die includes an outer guide barrel, an inner guide barrel, two water opening folding bends and a pressing plate; the inner guide barrel is sleeved with the outer guide barrel, and is partial to one side of the outer guide barrel, and the inner guide barrel and the outer guide barrel are fixedly connected; a feeding groove is formed in the outer guide barrel; the two water opening folding bends are symmetrically connected to one side of an outlet end of the outer guide barrel; the water opening folding bends are U-shaped members; and the pressing plate is fixedly arranged on outlets of the outer guide barrel and the inner guide barrel. In use, a collar material passes through a gap between the outer guide barrel and the inner guide barrel, two water openings at two sides of the collar material are brought out via the two water opening folding bends, and in this time, a certain traction force is applied to the two water openings through traction, fixed-location continuous discharging of the two watering openings can be achieved at the outlets of the two water opening folding bends, a water opening of a clothes body is placed on the two water openings of the collar material, i.e., the outlets of the folding bends, and the high speed sewing machine can achieve high speed continuous sewing.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a guiding folding die for a high-speed sewing machine. Background technique [0002] In the prior art, the knitted jacket collar is sewn on a conventional sewing machine. The sewing method is that the operator inserts the upper nozzle of the woven material into the needle row of the disc machine as required to realize the positioning of the upper nozzle of the material, and then inserts the lower nozzle of the material into the row of needles as required. on the needle to realize the positioning of the nozzle of the collar, and then insert the nozzle of the body into the needle row according to the requirements to realize the positioning of the nozzle of the body, and then start the sewing machine to enter the sewing state, and sew along the neckline in this way After a period of time, press and insert the upper nozzle of the next section of material, the nozzle of the...

AI Technical Summary

Problems solved by technology

This method is inefficient. For the upper collar work of thin knitted fabrics, an operator can only sew more than 70 pieces per shift on average, and can only sew about 170 pieces for medium-thick fabrics. The technical requirements are also high, and it is very easy to cause injury to the operator's fingers

The shortcomings of the above-mentioned existing methods are obvious, and the reason why they have been used all the time is that it is impossible to find a method and device that can quickly and accurately position the soft body nozzle between the upper nozzle and the lower nozzle. , so it is impossible to sew the collar with a high-speed sewing machine, which needs to be solved urgently
