Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shoemaking process, and particularly relates to a method for automatically threading a shoe string by using a flyknit flat knitting machine. BACKGROUND

[0002] The flyknit shoe upper is a popular shoe upper processing technology in China at present, and the shoe upper processed by the processing method can make the foot more comfortable and conducive to sports.

[0003] In the existing flyknit shoe upper process, no document about automatically threading a shoe string by using a flyknit process is disclosed, and the traditional shoe string threading process needs to be manually performed, that is, a hole for threading a shoe string is knitted on the flyknit shoe upper processed by using a computer flat knitting machine by a flyknit process, and after the shoe upper is taken off, the shoe string is manually threaded through the hole by using a crochet needle to achieve the threading effect on the shoe upper.

[0004] The traditional shoe string threading process consumes a large amount of labor cost and time cost. SUMMARY

[0005] The present application solves the technical problem of providing a method for automatically threading a shoe string by using a flyknit flat knitting machine instead of manual work.

[0006] In order to solve the above technical problem, the technical scheme adopted by the present application is as follows:

[0007] The method for automatically threading a shoe string by using a flyknit flat knitting machine comprises the following steps:

[0008] S1: while the first yarn connected with the first yarn needle is knitted on the front bed by the first system, the front bed needle plate is ejected, and a left-to-right knitting action is performed; while the second yarn connected with the second yarn needle is knitted on the back bed by the second system, the back bed needle plate is ejected, and a left-to-right knitting action is performed; the third yarn needle is driven to fly between the front and back needle plates from left to right between the front bed anvil plate and the back bed needle plate, and no knitting action is performed, and the needle plate is not ejected;

[0009] S2: the back bed yarn is flipped to the front bed by a needle flipping action at a distance of n needles in the next row, the first yarn is knitted on the front bed by the first system at the same time, the front bed needle plate is ejected from right to left, the second yarn is knitted on the back bed by the second system at the same time, and the back bed needle plate is ejected from right to left, covering the shoe string.

[0010] Further, in the method for automatically threading a shoe string by using a flyknit flat knitting machine, the number of the third yarn needle is between the numbers of the first yarn needle and the second yarn needle.

[0011] Further, in the method for automatically threading a shoe string by using a flyknit flat knitting machine, the numbers of the second yarn needle, the third yarn needle and the first yarn needle are continuous.

[0012] Further, in the method for automatically threading the shoe cord of the flyknit flat knitting machine, the first yarn nozzle is selected from a No. 5 yarn nozzle.

[0013] Further, in the method for automatically threading the shoe cord of the flyknit flat knitting machine, the second yarn nozzle is selected from a No. 3 yarn nozzle.

[0014] Further, in the method for automatically threading the shoe cord of the flyknit flat knitting machine, the third yarn nozzle is selected from a No. 4 yarn nozzle.

[0015] Further, in the method for automatically threading the shoe cord of the flyknit flat knitting machine, the method further comprises repeating the S1 and the S2.

[0016] Further, in the method for automatically threading the shoe cord of the flyknit flat knitting machine, in the S2, the back bed yarn is flipped to the front bed and pressed into the intermediate shoe cord through the needle flipping action at a distance of n needles in the next row, and specifically, the back bed yarn is flipped to the front bed and pressed into the intermediate shoe cord through the needle flipping action at a distance of 8-10 needles in the next row.

[0017] Further, in the method for automatically threading the shoe cord of the flyknit flat knitting machine, in the S2, the back bed yarn is flipped to the front bed and pressed into the intermediate shoe cord through the needle flipping action at a distance of n needles in the next row, and specifically, the back bed yarn is flipped to the front bed and pressed into the intermediate shoe cord through the needle flipping action at a distance of 9 needles in the next row.

[0018] The method has the advantages that the shoe cord to be threaded is connected to one of the yarn nozzles of the flyknit flat knitting machine, the threading action of the shoe cord is combined in the process of knitting the shoe upper through a specific knitting program, the flyknit flat knitting machine can automatically complete the threading process of the shoe cord in the knitting process, manual threading of the shoe cord after the shoe upper is taken off is no longer needed, the production efficiency is greatly improved, the labor cost is reduced, and damage to the shoe upper caused by improper operation during manual threading of the shoe cord is avoided.
