Detailed description of the invention:
With specific embodiment, the invention will be further described below, sees Fig. 18:
A kind of rotation cutting facility, including lower axle 1, is arranged with motion knife rest 2 outside lower axle 1, arranges on motion knife rest 2
Having cutter one, the present embodiment is set as that moving knife 3, motion knife rest 2 are connected with clutch, and clutch is driven by power part and makes fortune
Movable knife rack 2 rotates or separates together with lower axle 1, in conjunction with time, motion knife rest 2 rotates together with lower axle 1, and moving knife 3 realizes with cutter 24
Rotating trimming action, wherein cutter 24 can be stationary knife 4, it is also possible to be moving knife.When cutter 24 is stationary knife, it is arranged on machine by screw
On shell base plate 10, rotated by the i.e. moving knife 3 of cutter one and be engaged trimming action with stationary knife；During as moving knife, it is arranged on another
On knife rest, rotated by this knife rest motion band moving knife two and be engaged trimming action with cutter one.During separation, lower axle 1 rotates, motion
Knife rest 2 does not rotates, and does not the most carry out trimming action.
The present invention, departing from the trimming cam in existing structure, the action utilizing lower axle 1 main motion to rotate a circle, completes one
Secondary trimming process, from initial position, rotates a circle, is eventually returned to initial position, completes a trimming.Motion can be realized
The simplification of process, and simplify the part of cutting facility, realize sewing machine trimming more reliably.
According to actual design situation, being arranged with lower axle protheca 5 outside described lower axle 1, motion knife rest 2 is set in lower axle protheca 5
Outward, motion knife rest 2 is rotated together with lower axle 1 by the drive action of clutch, or separates with lower axle 1.
The present embodiment can be attached with motion knife rest 2 by motion back-up ring 7, and structure is as follows: the front portion of described lower axle 1

It is provided with resetting-mechanism in drive shaft 11, and drive shaft is connected with power part.
Situation that motion knife rest 2 do not moves that what above-mentioned clutch was corresponding is.
Spring 13 has the effect of reset, when the active force of power part disappears, pushing pin 9 can be made to reset.
Clutch can also use following structure: described clutch includes being arranged on the peace of relevant position on base plate 10
Drive shaft 11 in dress hole, drive shaft 11 can move linearly in installing hole, and the head in drive shaft 11 is provided with shift fork 14, dials
Being provided with shift fork head 15 on fork 14, be provided with draw-in groove 16 on motion knife rest 2, shift fork head 15 is arranged in draw-in groove 16, drive shaft
It is provided with resetting-mechanism on 11, and drive shaft is connected with power part.
Clutch, it may also is that include being arranged on the drive shaft 11 in the installing hole of relevant position on base plate 10, drives
Axle 11 can move to rotating shuttle 6 direction or away from rotating shuttle 6 direction in installing hole, and the head in drive shaft 11 is provided with push pedal 12,
One end of push pedal 12 is sleeved on lower axle protheca 5 or motion knife rest 2, and push pedal 12 axially can move along lower axle protheca 5 or the knife rest 2 that moves
Dynamic, described push pedal 12 contacts connection with motion knife rest 2, is provided with spring, push pedal 12 between motion knife rest 2 and motion back-up ring 7
Move to motion back-up ring 7 direction, promote motion knife rest 2 compression spring to move the pushing pin 9 making motion knife rest 2 to motion back-up ring 12
Being connected with the pusher head 8 of motion back-up ring 12, described drive shaft 11 is provided with resetting-mechanism, and drive shaft 11 is with power part even
Connect.Spring can make motion knife rest 2 reset.
The corresponding motion knife rest 2 of above two clutch is the situation of movement.
After completing trimming, motion knife rest 2, clutch are required to reset, owing to the clutch of the present invention is not interfered
Motion knife rest 2 is around lower axle protheca 5 or rotatable around its axis, and therefore, described resetting-mechanism can select to drive drive shaft 11 to move
Power part, say, that resetting-mechanism is power part.Power part can be connected by joint with drive shaft 11, by
Motion knife rest 2, clutch is driven to reset when power part resets.
Certainly, resetting-mechanism can also be back-moving spring 17.Now, the tail end of described drive shaft 11 uses with power part
Contact connects.Tail end in drive shaft 11 is provided with catch 18, and in order to easy for installation, the catch 18 of the present embodiment selects card
Spring.One end of back-moving spring 17 holds out against on catch 18, the other end holds out against on base plate 10, when power part power disappears,
Motion knife rest 2, clutch is driven to reset by back-moving spring 17.
Power part of the present invention can select electric magnet 19 or cylinder or motor etc..The present embodiment selects electric magnet
19。
The present invention uses rotation trimming, and therefore, traditional moving knife cannot be applicable to this structure.Described cutter 1 includes
There is the installation portion 20 being connected with motion knife rest 2, be provided with blade body 21, blade body 21 and installation in the side of installation portion 20
The L-shaped structure in portion 20, is provided with point of a knife 22 in the front end of blade body 21, and rear end is provided with cutting edge 24.Bracing wire for convenience,
The front side of cutting edge 24 is provided with bracing wire groove 23.
Motion knife rest 2 of the present invention is that motion knife rest 2 is positioned at anterior station when being combined with lower axle 1 or motion back-up ring 7,
Motion knife rest 2 separates luck movable knife rack 2 with lower axle 1 or motion back-up ring 7 after resetting and is positioned at rear portion station.
The operation principle of the present invention:
When being made without trimming, pushing pin 9 on motion knife rest 2 or motion knife rest 2 and clutch are at back-moving spring
The pushing pin 9 being positioned on rear portion station motion knife rest 2 under the effect of 17 does not contacts with the pusher head 8 of motion back-up ring 7, motion back-up ring
7 rotate together with lower axle 1, do not drive motion knife rest 2 to rotate together.
When control system receives trimming order, before rotating shuttle 6 forwards trimming angle to, control system is sent out to power part
Signal, power part starts, and drives drive shaft 11 anteriorly to move.
Now, when selecting the clutch of shifting fork structure, shift fork head 15 drives motion knife rest 2 to move to anterior station；
When selecting the clutch of push pedal 12 structure, push pedal 12 compression spring, moves pushing pin 9 to anterior station；
On the moving line that pushing pin 9 enters pusher head 8, treat that motion back-up ring 7 is rotated further and make pusher head 8 suffer promotion
Pin 9, motion back-up ring 7 rotates along with rotating shuttle 6 together with motion knife rest 2, and the moving knife 3 being arranged on motion knife rest 2 is in lower axle 1
The heart rotates along rotating shuttle 6 direction of rotation, point of a knife 22 through the wire loop of upper thread 25, bracing wire groove 23 with upper thread 25 and bottom line 26 to
Stationary knife 4 moves, and when the cutting edge 24 of the moving knife with line is engaged with the cutting edge of stationary knife 4, is cut off by line, completes trimming action.
After being cut off by line, motion back-up ring 7 is rotated further with motion knife rest 2, until eedle 27 is stopping the stopping of pin position, moving knife
3 return to stop position, wait trimming operation next time.
Above-described embodiment is only one of presently preferred embodiments of the present invention, not limits the practical range of the present invention with this, therefore:
The equivalence change that all shapes under this invention, structure, principle are done, within all should being covered by protection scope of the present invention.
