The utility model is further described example.
As Figure 1-4, the utility model discloses one kind to cut pendulous device, and it includes positioning bearing end seat end 1, floated
Moving axis bearing end 2, swing arm 3, square rail 4, eccentric shaft 5 and reducing motor 6, described positioning bearing seat end 1 and square rail 4
One end axially connect, the other end of the floating bearing bracket end 2 and square rail 4 is axial to be connected；One end of the swing arm 3 with
One end connection of square rail 4, the other end are connected with eccentric shaft 5；The eccentric shaft 5 is connected with reducing motor 6, passes through the electricity that slows down
Machine 6 drives the deflection of the low speed of eccentric shaft 5.
After said structure, the utility model by one end of positioning bearing seat end square shaped guide rail carry out radially and its
Axially position；And the top and bottom of swing arm are respectively at square rail and eccentric axis connection, due to square rail and square rail
It is fixedly connected, so swing arm can drive square rail to swing when swinging, while swing arm can be in the drive of eccentric shaft
Lower swing；And reducing motor can be with output mechanical energy, and then drive eccentric shaft that low speed deflection occurs；When swing again, float
The bearing block end square shaped guide rail other end carries out radial positioning, can axially float.
Furtherly, in addition to cutting structure 7, the cutting structure 7 include carving knife 70, blade bearing 71, blade holder 72
With knife rest fixed seat 73, the carving knife 70 is screwed passes through screw installed in the side of blade bearing 71, blade bearing 71
Installed in the lower end of blade holder 72, the upper end of blade holder 72 is screwed in knife rest fixed seat 73, and the knife rest is fixed
Seat 73 is arranged on square rail 4；2 pieces of carving knives are respectively installed in above-mentioned each blade holder 72.
Using said structure, the utility model is by the way that carving knife to be fixed on to the side of blade bearing, and blade bearing is arranged on
The lower end of blade holder, so when knife rest fixed seat is driven by square rail, blade holder can be driven, and then carving knife can
With with the swing of square rail, and the mobile cutting in the certain limit of film cutting.
Furtherly, elastic set screw 74 is also equipped with the knife rest fixed seat 73, passes through the elastic set screw
74 come adjust in knife rest fixed seat 73 it is elastic, and then adjust the position of carving knife；By elastic set screw, knife can be controlled
Frame fixed seat it is elastic, if needing to change the distance between knife rest fixed seat, that is, the distance cut, knife rest can be unclamped
The elastic set screw of fixed seat, then follow rest fixed seat, then carry out tightening fixation.
Furtherly, the quarter code 41 for elastic set screw adjusting position is additionally provided with the square rail 4；Pass through
These, which carve code, can select the displacement of follow rest fixed seat.
Furtherly, be additionally provided with the frame fixed seat 73 one be used for measure carve the scale 8 of code, and the scale is in three
It is angular；By the scale can accurate follow rest fixed seat distance so that knife rest fixed seat will not occur after moving again
The unbalanced situation of blade holder, cause the film of cutting uneven.
Furtherly, the swing arm 3 is connected one end with eccentric shaft 5 and is arranged to " U " prong 51, and the diameter of the prong 51 is just
Equal to the diameter of eccentric shaft；By the " u "-shaped prong, so swing arm be able to can be fixedly connected with eccentric shaft, allow swing arm can
Driven well by eccentric shaft.
Furtherly, the reducing motor 6 is arranged on the side of eccentric shaft 5, and positioned at the outside of eccentric shaft 5；Due to subtracting
