Specific embodiment

For it is relatively intuitive, be fully understood by the technical solution of the utility model, now just combine the progress of the utility model attached drawing Unrestricted feature description is as follows:

As shown in Figures 1 to 5, a kind of herringbone vehicle automatic shearing mechanism is passed including bottom plate 1, the rotating shuttle being arranged in bottom plate 1 Moving axis 2, the cam 3 covered on rotating shuttle transmission shaft 2 are cut with the knife bar component 4 of the cooperation of cam 3, with what 4 end of knife bar component was connect Line knife 5 and the trimming electromagnet 6 for driving knife bar component 4 to move left and right, bottom plate 1 is interior to be equipped with sliding rail 7, one end of knife bar component 4 It is slidably matched with sliding rail 7；Knife bar component 4 includes the connecting rod 41 to offset with 3 side of cam, and 6 end of trimming electromagnet has Armature 61 offsets with 41 side of connecting rod.

Trimming electromagnet 6 is push-pull electromagnet, and trimming electromagnet 6 is fixed in bottom plate 1 by a bracket 12；In trimming The ipsilateral connecting rod 41 of electromagnet 6 is equipped with the second through-hole 414 for connecting a reset spring 13,414 one end of reset spring It is hooked in the second through-hole 414, the other end is hooked on bottom plate 1；Although trimming electromagnet 6 itself has spring, consideration has other Component, therefore increase reset spring 13, so that inter-agency run smoothly；1 bottom of bottom plate has the stationary knife 14 cooperated with thread trimmer 5, Convenient for trimming.

Sliding rail 7 has the groove 71 slided for knife bar component 4；Sliding rail 7 is fixed by screws in 1 bottom plate of bottom plate, and sliding rail 7 pushes up Portion has the cover board 15 for being screwed connection, plays protection and position-limiting action, prevents knife bar 42 from skidding off.

Knife bar component 4 further includes the knife bar 42 being slidably matched with groove 71,42 one end of knife bar extend after sliding rail 7 with trimming Knife 5 connects, and thread trimmer 5 is fixed by screws in 42 one end of knife bar, and knife bar 42 can slide in groove 71, and the other end passes through 10,000 It is hinged to link block 43 and connecting rod 41.

Connecting rod 41 is hinged far from universal that one end of link block 43 and the fixed block 8 being fixed in bottom plate 1, and connecting rod 41 is pushed up Portion has the convex block 411 to offset with armature 61, and 41 bottom of connecting rod has the roller 412 to offset with cam 3, makes movement more flat Surely.

Fixed block 8 is hinged with fixed block by connecting rod by a round pin 9 and a retaining ring 10, and round pin 9 is screwed solid Determine 8 middle part of block, connecting rod 41 is equipped with the first through hole 413 rotatably cooperated with short pin 9, circle far from universal that one end of link block 43 9 top of pin is equipped with the retaining ring 10 being screwed, and limits link block 41, plays a protective role.

3 side of cam has the slope surface 31 to offset with roller 412, and slope surface 31 has top of the slope 311 and bottom of slope 312, for even Extension bar is slided in top of the slope 311 and 312 section of bottom of slope.

The limited block 11 close to slope surface 31 is equipped in the middle part of rotating shuttle transmission shaft 2, there are gap between limited block 11 and cam 3, It allows roller 412 to have activity space, is unlikely to stuck.

The utility model specific working mode is as follows: when being not necessarily to trimming, because 13 one end of reset spring is hooked in the second through-hole 414, the other end is hooked on bottom plate 1, and is in tensional state, so that the pulling force that oriented side is drawn close always of connecting rod 41, so that Roller 412 in connecting rod 41 is against on limited block 11；When needing trimming, trimming electromagnet 6 starts, on trimming electromagnet 6 Armature 61 push convex block 411, allow connecting rod 41 to move to the direction of 13 reaction force of reset spring, allow connecting rod 41 around circle Pin 9 rotates, so that roller 412 is just against the bottom of slope 312 of slope surface 31, at this point, the rotation band moving cam 3 of rotating shuttle transmission shaft 2 moves, Roller 412 is allowed to move towards top of the slope 311, so that connecting rod 41 be driven to move, then the knife bar 42 that links allows sliding block on knife bar 42 421 horizontally slip in groove 431, are connected to thread trimmer 5 on knife bar 42 also equal motion, therefore thread trimmer 5 is matched with stationary knife 14 It closes and completes a trimming action.

Certainly, the above is only the preferred embodiments of the present utility model only, and therefore, it does not limit the patents of the utility model Range, all with the utility model specification and schema content institute, simply modification and equivalent structure change for it, should all similarly wrap Within scope of patent protection contained in the utility model.
