Fig. 2 is the sectional view in A-A face in Fig. 1.
Detailed description of the invention
Below, with reference to accompanying drawing, this utility model is more fully illustrated, shows shown in the drawings of of the present utility model
Example embodiment.But, this utility model can be presented as multiple multi-form, is not construed as being confined to describing here
Exemplary embodiment.And it is to provide these embodiments, so that this utility model is fully and completely, and by of the present utility model
Scope fully conveys to those of ordinary skill in the art.
For ease of explanation, here can use such as " on ", the space relative terms such as D score " left " " right ", be used for
Shown in bright figure a element or feature are relative to another element or the relation of feature.It should be understood that except in figure
Outside the orientation illustrated, spatial terminology is intended to include device different azimuth in use or operation.Such as, if in figure
Device is squeezed, be stated as being positioned at the element of other elements or feature D score will be located into other elements or feature " on ".Cause
This, exemplary term D score can comprise upper and lower both orientation.Device can otherwise position (90-degree rotation or be positioned at
Other orientation), relatively illustrate used herein of space correspondingly to explain.
As shown in Figure 1-2, this application provides a kind of Qian Mo mechanism, described Qian Mo mechanism includes that frame (is not shown in figure
Go out), compression module 100, action bars 109, mobile roller 106 and fixing roller 110；Wherein, the upper and lower side of described compression module 100 divides
Be not fixed in frame by upper fixed block 101 and lower fixed block 102, fixed piece 101 and described lower fixed block 102 it
Between be connected by lead 103, described lead 103 is socketed with movable block 104, described movable block 104 can be along lead 103
Axially slide up and down；It is provided with back-moving spring 105 between described movable block 104 and fixed piece 101；Described mobile roller
106 bottoms being rotatably arranged on described movable block 104；The top of described movable block 104 is provided with a square orifice 107, institute
Being provided with lock cam 108 in stating square orifice 107, described action bars 109 is rotatably arranged in described frame, and described lock
Tight cam 108 is connected with the end of described action bars 109；Described fixing roller 110 is rotatably arranged on described lower fixed block 102
In；The upper edge of square orifice 107 under the effect of back-moving spring 105 all the time upper end face with lock cam 108 contact.
Lock cam 108 is irregular similar round structure, and the radius of its upper and lower two curved surfaces is different.Qian Mo mechanism includes
Two compression modules, two compression modules are symmetricly set on the two ends of described frame, two compression modules share one group of action bars,
Mobile roller and fixing roller.Fixing roller 110 is positioned at the underface of mobile roller 106.
Qian Mo mechanism also includes drive mechanism 200；Described drive mechanism 200 is connected with described fixing roller 110, is used for driving
Fixing roller 110 rotates；Mobile roller 106 is driven.One end of action bars 109 is provided with adjustment handle 111；Preferably, hands is adjusted
Handle 111 and drive mechanism 200 are separately positioned on the both sides of frame.
The application to lead film mechanical work principle as follows: under the effect of back-moving spring 105, square orifice 107 upper along beginning
Contact with end face on lock cam 108 eventually, rotation lock cam 108, when the minor radius curved surface of lock cam 108 forwards to above,
With when on square orifice 107, edge contacts, movable block 104 moves down, and mobile roller 106 contacts with fixing roller 110, and contact force is bullet
Power, protection device；When the large radius curved surface of tight cam 108 forwards to above, with on square orifice 107 along contact time, on movable block 104
Moving, mobile roller 106 separates with fixing roller 110.Owing to mobile roller 106 feeds back to the contact force of lock cam 108 to action bars 109
Moment from far away less than operation time adjust handle 111 moment that action bars 109 is produced, so mechanism can realize self-locking.
During work, film is placed between mobile roller 106 and fixing roller 110, pulls action bars 109, be locked roller 110 with
Mobile roller 106, thus clamp film.Drive mechanism 200 drives fixing roller 110 to rotate, in the effect of the frictional force that coupling mechanism force produces
Under, film moves forward, fixing roller 110 also concomitant rotation, thus realizes leading film function.
Described above simply to illustrate that this utility model, it is understood that this utility model is not limited to above enforcement
Example, meets the various variants of this utility model thought all within protection domain of the present utility model.
