Wherein, the name corresponding to the Reference numeral in accompanying drawing is called:
1-cylinder, 2-piston fork arm, 3-crank connecting link, 4-alignment pin, 5-linkage block, 6-cutter connecting rod, 7-shear knife, the directed block of 8-, 9-gathering sill, 10-compresses anvil, the defeated yarn roller of 11-, 12-press roller, 13-slewing rollers, 14-yarn, 15-cut groove.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
Fig. 1 shows the structural representation of the yarn-feeding device of fiber placement machine according to an embodiment of the invention.The yarn-feeding device of a kind of fiber placement machine as shown in Figure 1, comprises cylinder 1, piston fork arm 2, crank connecting link 3, linkage block 5, press roller 12, defeated yarn roller 11 and break-in roller 13; Described cylinder 1, piston fork arm 2, crank connecting link 3 are respectively two, each connection piston fork arm 2 on described two cylinders 1, each connection crank connecting link 3 on described two piston fork arms 2; Described two crank connecting links 3 are all connected with linkage block 5, described press roller 12 is rotationally connected with described linkage block 5, described defeated yarn roller 11 is arranged on below described press roller 12, described break-in roller 13 is positioned on same level height with described press roller 12, and yarn 14 enters defeated yarn roller 11 after being turned to by described slewing rollers 13.
In another embodiment of the invention, described linkage block 5 can be triangle linkage block.
Described linkage block 5 is provided with alignment pin 4.
Also can comprise cutter connecting rod 6, described cutter connecting rod 6 is connected with described linkage block 5.
