The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
With reference to figure 1,2, a kind of comprehensive feed sewing machine comprises thorn material thread take-up mechanism, comprehensive feed mechanism, automatic shearing mechanism, trimming mechanism, chip removal device etc.The main feeding part of feed mechanism comprises needle plate, shank, interior presser feet, outer presser feet and feed dog, interior presser feet, eedle, the synchronous feeding of feed dog, after feeding finished, outer presser feet was pressed in sewing on the needle plate, the eedle of shank lower end thorn material is finished feeding and the action of thorn material then.These settings all are conventional, so here do not describe in detail.
The comprehensive synchronous vertical trimming Sewing machines of feeding automatic shearing also comprises a trimming mechanism that can move along the vertical direction, and this trimming mechanism comprises knife bar cam 19, needle bearing 18, connecting rod 2, guide runner 5, arbor adapter 6, knife bar 7, clutch knob 8, on-of pin 20, first knife rest 9, second knife rest 21, knife rest first guide pillar 10, the second knife rest guide pillar 22, knife rest leading truck 17, knife rest adjustment screw 23, cutting knife 14.The knife bar cam 19 that is installed on main shaft 1 and the needle bar crank 3 is power origins of whole trimming mechanism, the location of knife bar cam 19 is when shank 29, interior presser feet 30 are minimum, first knife rest 9 rises to highest point, and needle bar crank 3 is connected the location with knife bar cam 19 by pin.Movement relation between them is: when shank 29,30 liftings of interior presser feet, outer presser feet begins binder, cutting knife 14 beginnings descend with mechanism and cut edge the presser feet binder time outside, after side cut is finished, knife rest begins to rise, outer presser feet promotes, and interior presser feet binder, shank begin the thorn material and cooperate feeding with feed dog 24, finish actions such as thorn material, feeding, side cut.
The embodiment of trimming mechanism is to rotate and the generation center displacement by main shaft 1 rotating band moving knife bar cam 19, thereby drivening rod 2 is made eccentric motion; Because under the effect of guide runner 5, make the center displacement of knife bar cam 19 pass through being connected of connecting rod 2 and arbor adapter 6, the motion that drives knife bar 7 just changes vertical motion up and down into; Utilize the connection of an arrangement of clutch that knife bar 7 is connected with knife rest leading truck 17, first knife rest 9, second knife rest 21 are connected on the knife rest leading truck 17 in succession, first knife rest 9 has the side cut width adjusting function of directions X, and second knife rest 21 has the cutter location regulatory function of Y direction.The direction along the first knife rest guide pillar 10, the second knife rest guide pillar 22 of knife rest leading truck 17 is moved, and the first knife rest guide pillar 10 has the position of adjusting knife rest leading truck 17 and the lightest state that slides; The cutting knife 14 that is installed on first knife rest 9 is also done vertical motion with motion of mechanism, cooperates and cuts edge with cutter stator on being fixed on needle plate 29.The cloth bits that downcut are by the importing of cloth bits baffle plate 11, import to chip removal bucket 13, food tray chip removal bucket 15 and are discharged in the trash receptacle by scrap chute.
The top arrangement of clutch of mentioning comprises parts such as clutch knob 8, on-of pin 20, control knife bar 4, back-moving spring 31.Under the situation of generally not cutting edge, knife bar 7 is under the state that separates with knife rest leading truck 17, when needs are cut edge, press control knife bar 4, because the moving down of control knife bar 4 promotes knife rest leading truck 17 and moves down, when the clutch slot of knife rest leading truck 17 with on-of pin 20 during at same position, on-of pin 20 is owing under the effect of built-in spring, on-of pin 20 inserts the clutch slot of knife rest leading truck 17 automatically, thereby drives the motion of whole cutter frame mechanism.If under the situation that does not need to cut edge, pulling clutch knob 8 makes on-of pin 20 break away from the clutch slot of knife rest leading truck 17, knife rest leading truck 17 is because the effect of back-moving spring 31, automatically reset to the extreme higher position, thereby the motion of whole knife rest and knife bar 7 is thrown off, reach the purpose of not cutting edge.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
