The specific embodiment

For structure of the present utility model, shape and function can be understood better, below by several embodiment and discuss in detail in conjunction with the accompanying drawings.

As shown in Figure 1 and Figure 2, be the schematic perspective view of the utility model flat braiding machine and the handpiece structure schematic perspective view of flat braiding machine respectively.

As shown in Figure 3, be that the utility model list peak formula is moved the schematic diagram of pin cam system, it comprises cam system and following cam system, block stitch triangle 9 about cam system comprises under described, play stitch triangle 10, left side needle selecting foot triangle 11, right needle selecting foot triangle 12, about whole stitch triangle 13, and the described cam system that goes up comprises herringbone triangle 1, central cam 2, rise cam 3, left side stitch cam 4, right stitch cam 5, pin triangle 6 is blocked on a left side, pin triangle 7 is blocked on the right side, about whole pin triangle 8, above-mentioned these all be existing structure, and characteristics of the present utility model are: the described cam system that goes up comprises that also unimodal formula moves pin triangle 14 and connect pin triangle 15 with left-right swing type.

It is left-right symmetry structures that described unimodal formula is moved pin triangle 14, and it protrudes in the symmetry axis position and forms a top 141;

Described left-right swing type connects pin triangle 15 can be around the angle of the pre-sizing of its pivot 151 swings, and described pivot is positioned at described unimodal formula and moves on the symmetry axis of pin triangle 14.

Utilize said structure, the utility model list peak formula is moved the pin cam system can finish moving the pin action and connecing the pin action of unlimited direction smoothly, and because necessary action of rising only takes place once for it, can reduce the possibility of pulling of fabric yarn.

As shown in Figure 4, it is the utility model user mode schematic diagram, the pin heel 21 that described single peak formula is moved the relative knitting needle 20 of the pin cam system operation of turning left from the right side, the unimodal formula of Vee formation system 22 is moved pin triangle 14 and is protruded from triangle group plane, each pin heel 21 is formed move the pin action, when pin heel 21 is pushed away peak by described top 141, yarn on the corresponding knitting needle 20 can be strained, unimodal then formula is moved pin triangle 14 and is continued to move, and low level is also got back in described pin heel 21, and yarn is drawn pine.Meanwhile, in the preceding cam system 23, described left-right swing type connects pin triangle 15 toward the moving direction deflection of moving the pin cam system in contrast to single peak formula, and the described left-right swing type peak that connects pin triangle 15 promotes described pin heel 21 and finishes and connect the pin action.Because described left-right swing type connects pin triangle 15 and has deflection, described left-right swing type connects between the peak of pin triangle 15 and the symmetry axis that unimodal formula is moved pin triangle 14 has one section predetermined distance, so, in Vee formation system 22 and the preceding cam system 23, moving the pin action and connecing between the pin action of pairing knitting needle 20 has the preset time gap, finished smoothly thereby make to move the pin action and connect the pin action.Those skilled in the art should be appreciated that pin heel 21 operation from left to right that moves the relative knitting needle 20 of pin cam system when described single peak formula, and then above-mentioned left-right swing type connects pin triangle 15 deflection of turning left, and can finish equally and move the pin action and connect the pin action.
