The detailed description and technical content of the present invention are described as follows in conjunction with the drawings:

1 to 4, the present invention proposes a flat knitting machine yarn feeder 20 with a variable yarn feeding position. The flat knitting machine yarn feeder 20 is used in a flat knitting machine 100 corresponding to two needle beds 11, 12 The area defined in the middle. Moreover, the yarn feeder 20 of the flat knitting machine of the present invention includes a driving mechanism 21 and a yarn feeding mechanism 22. The driving mechanism 21 has a motor 23 and a driving plate 24 connected to the motor 23. The motor 23 is controlled by an electronic signal, and the motor 23 receives The timing of the electronic signal is when the weaving condition of the flat knitting machine 100 changes. Furthermore, the drive plate 24 is driven by the motor 23 to move in one dimension.

On the other hand, referring back to FIGS. 2 to 4, the yarn feeding mechanism 22 has a connecting plate 25 connected to the driving plate 24 and a yarn feeding arm 26 assembled with the connecting plate 25. Wherein, the connecting plate 25 is designed to move with the driving plate 24. In one embodiment, the driving board 24 has a protrusion 241 disposed at the end and protruding toward the connecting plate 25, and the connecting plate 25 has a receiving track 257 in which the protrusion 241 is disposed, wherein the receiving The rail 257 does not need to be provided with concave and convex portions, and the receiving rail 257 actually enables the protrusion 241 to drive the adapter plate 25.

In addition, the adapter plate 25 has a guide hole 251 which is not a circular hole. In one embodiment, the guide hole 251 has two oppositely arranged inclined surfaces 252 and 253, and the two inclined surfaces 252 and 253 are located on the On a movement track of the yarn feeder 20 of the flat knitting machine. Further, the guide hole 251 may be trapezoidal. In addition, the yarn feeding arm 26 has a guide post 261 arranged in the guide hole 251, and the length of the guide post 261 is set to be able to at least contact the guide hole 251 of the adapter plate 25. Furthermore, the yarn feeding arm 26 has a yarn feeding end 262 facing one of the needle beds 11 (or 12).

Please also refer to Figures 1 to 4, in order to specifically illustrate the implementation of the flat knitting machine feeder 20 of the present invention, the initial state of the flat knitting machine feeder 20 is shown in Figure 3, and the adjustment is shown in Figure 4 After state. Wherein, in the initial state, the drive mechanism 21 receives the electronic signal to start work, and then the drive plate 24 is driven to perform a pushing stroke (as indicated by 240 in FIG. 3), and the drive plate 24 drives the adapter plate 25 performs a transposition stroke 254, which is actually a one-dimensional movement. Further, when the adapter plate 25 runs the transposition stroke 254, the guide hole 251 moves along with the adapter plate 25, so that the guide post 261 changes in the guide hole 251 accordingly. 4), when the guide post 261 changes its position, the yarn feeding arm 26 produces a displacement (movement direction 291 as shown in FIG. 4), and then changes the yarn feeding end 262 relative to the The yarn feeding position of the needle bed 11 (or 12) changes the yarn feeding position of the yarn feeder 20 of the flat knitting machine.

3 and 4, when the guide hole 251 has the two inclined surfaces 252, 253, the guide post 261 will only contact the two inclined surfaces according to a current movement direction 27 of the flat knitting machine feeder 20 One of 252 and 253. Further, when the guide post 261 contacts one of the two inclined surfaces 252, 253, it will be located between a vertex 255 and a bottom point 256 of each inclined surface 252 (or 253), or be located at the vertex 255 or The bottom is above 256. Moreover, when the guide hole 251 is a trapezoid, the vertex 255 refers to one of the top corners of the trapezoid, and the bottom point 256 refers to one of the bottom corners of the trapezoid.
