Description
Technical field
The utility model is related to rubber manufacturing machinery technical field, especially a kind of rubber sheet guided cutting machine ellipse arc rotating roller knife.
Background technology
In existing rubber tyre production technology, rubber sheet guided cutting machine is to be applied to the indispensability of auxiliary system on mixer to set
Standby, effect is to be transported to glue after carrying out segmentation cut-out according to the weight of technological requirement after stacking film stretching expansion in heaps
Feed weighing is carried out on material scale, the film after weighing does not allow to exceed technological requirement.
The rubber sheet guided cutting machine that generally uses at present, is to drive rotary knife base by motor reducer, to drive rotating roller knife,
Rotating drum rotates, and forming rotary shifted reversed draw simultaneously using rotating roller knife and rotating drum stretches film, until by film
Cut-out.
The structure of the rotary knife base generally used on rubber sheet guided cutting machine at present is that rotary knife base cylinder periphery is provided with two
It is a along the symmetrically arranged mounting surface of its shaft, it is identical as the angle of rotary knife base shaft axis to be symmetrically installed face, at 6 °~9 °
Between.On this basis, rotating roller knife can not be by film severing, when rotating roller knife is installed to rotating knife using the structure of vertial knife edge
After on seat, in rotation process, what the blade of rotating roller knife was formed is a virtual parabolic shape, low between the senior middle school of both ends,
If rotating roller knife both ends and rotating drum are tangent, the middle section of rotating roller knife can not be tangent with roller, cannot incite somebody to action
Film severing；If the centre position of rotating roller knife and rotating drum is tangent, the both ends of rotating roller knife and rotating drum
It is staggeredly too big, blade can be burst apart.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts provides a kind of rubber sheet guided cutting machine ellipse arc rotation
Roller knife solves the problems, such as that rotary knife base mounting surface each point is differed to shaft axis distance, makes ellipse arc rotating roller cutter hub blade
On each point to shaft axis distance it is equal, rotary knife base rotate during, the elliptic arc of ellipse arc rotating roller cutter hub
Shape blade forms a virtual cylindrical shape, and there are one point and rotating drums always on the blade of ellipse arc rotating roller cutter hub
Keep tangent state.
The purpose of this utility model is achieved through the following technical solutions：A kind of rubber sheet guided cutting machine ellipse arc rotating roller
Knife, cooperation rotating drum complete film cut-out, and the rubber sheet guided cutting machine ellipse arc rotating roller knife includes rotary knife base,
There are two along the symmetrically arranged mounting surface of its shaft, mounting surface and rotary knife base shaft axis for the setting of rotary knife base cylinder periphery
Between with 6 °~9 ° of angle, be mounted on the ellipse arc rotating roller cutter hub with ellipse arc blade on each mounting surface,
Using the shortest distance a between rotary knife base shaft axis and rotating drum outer circle as the short radius of ellipse arc blade, with rotation
Line centered on tool apron shaft axis does a cylinder by radius of a, to be parallel to the flat of mounting surface residing for ellipse arc blade
Face, using the intersection point of the plane for being parallel to mounting surface and rotary knife base shaft axis residing for ellipse arc blade as ellipse arc
The central point of blade.
Preferably, the ellipse arc blade is located at side of the ellipse arc rotating roller cutter hub far from mounting surface, to
The longest distance that plane residing for the surface of side of the ellipse arc rotating roller cutter hub far from mounting surface intersects with the cylinder
For the long diameter of ellipse arc blade.
Preferably, the thickness of the ellipse arc rotating roller cutter hub is 19.05mm, to apart from mounting surface 19.05mm
And the long diameter that the longest distance that intersects with the cylinder of the plane for being parallel to mounting surface is ellipse arc blade.
Preferably, the length of the mounting surface is equal with the width of ellipse arc rotating roller cutter hub.
The utility model has the following advantages：
During the ellipse arc rotating roller cutter hub rotation of the utility model, ellipse arc blade is made to begin with rotating drum
Tangent state is kept eventually, and only tangent there are one putting；Noise when work is reduced simultaneously, successfully realizes the sanction of film
It is disconnected.
