A kind of packaging bar end chamfer cutter cutting mechanism
Technical field
The present invention relates to a kind of cutter, especially relate to a kind of packaging bar end chamfer cutter cutting mechanism.
Background technology
The packaging bar used in packaging industry, often need the inclined-plane processing end, in a three-dimensional packaging bight during for packing, three packaging bars perfections docking, based on this kind of purposes, described inclined-plane machining angle required precision higher, inclined-plane of the prior art cutter is hand shears, by manually providing power to carry out shearing work to packaging bar, cause the workload of shearing large, the labour intensity of workman is higher.
In addition due to the sheet of cutter of the prior art to be cross section be yi word pattern, carrying out in the guiding of shear direction to it, the skew in as easy as rolling off a log generation direction, thus affecting shear effect.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of structure simple, operation easily, and easily ensures the packaging bar end chamfer cutter cutting mechanism of shear effect.
The present invention in order to solve the problems of the technologies described above adopted technical scheme is: a kind of packaging bar end chamfer cutter cutting mechanism, be arranged in the frame of described cutter, described cutting mechanism is provided with the cutter that two are respectively used to shear packaging bar front end and tail end end chamfer, two cutters are oppositely arranged on the both sides of packing bar clipped position in described cutter, and be all obliquely installed towards this packaging bar clipped position, form V-shaped structure, two cutters are separately positioned in the cutter gathering sill of corresponding oblique setting, the afterbody of two cutters is connected with a connecting lever be hinged in frame separately, connecting lever swings around pin joint under the driving of respective cylinder, move back and forth along cutter gathering sill with carry its tools, thus the packaging bar through packaging bar clipped position is sheared.
Described connecting lever is L-shaped, its corner and frame hinged, its two ends are hinged with cutter and cylinder respectively.
The cross section of described cutter is inverted V-shaped, the shape of its upper and lower surface respectively with the mating shapes of the upper and lower internal face of cutter gathering sill.
The invention has the beneficial effects as follows:
Adopt cylinder to provide power for shear action, significantly reduce the labour intensity of workman; The structure of cutter is more reasonable, not only solves the problem that cutter in guiding is easy to laterally slide, and convenient processing, and more easily ensures the accuracy shearing result, ensures the required precision of shear product.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, concrete detailed description is further done to the present invention.
As shown in the figure, a kind of packaging bar end chamfer cutter cutting mechanism, be arranged in the frame 1 of described cutter, described cutting mechanism is provided with the cutter 5 that two are respectively used to shear packaging bar front end and tail end end chamfer, two cutters 5 are oppositely arranged on the both sides of packing bar clipped position in described cutter, and be all obliquely installed towards this packaging bar clipped position, form V-shaped structure, two cutters 5 are separately positioned in the cutter gathering sill of corresponding oblique setting, described cutter gathering sill is arranged in pilot unit 7, the afterbody of two cutters 5 is connected with a connecting lever 3 be hinged in frame 1 separately, connecting lever 3 swings around pin joint (bearing pin 4 namely in diagram) under the driving of respective cylinder, move back and forth along cutter gathering sill with carry its tools 5, thus the packaging bar below packaging bar clipped position and pilot unit 7 and between chopping block 8 is sheared.
Described connecting lever 3 is L-shaped, its corner and frame 1 hinged, its two ends are hinged with cutter 5 and cylinder respectively.
The cross section of described cutter 5 is inverted V-shaped, the shape of its upper and lower surface respectively with the mating shapes of the upper and lower internal face of cutter gathering sill.
In order to ensure that enough intensity can make again structure seem compact, described connecting lever 3 adopts tabular, and connecting lever and the frame 1 of described tabular be arranged in parallel.
Described cutter 5 cross section is inverted v-shaped, such structure carries out preventing cutter 5 from sliding along cutter 5 width in the process led at the pilot unit of use with the cutter gathering sill corresponding to the shape of tool, thus ensure the accuracy of shear action, the final required precision ensureing product.
Use the present invention original packaging bar can be cut into shear inclined-plane respectively with one two simultaneously, after original packaging bar proceeds to required fixed length position continuously, cutting mechanism is sheared again simultaneously, so repeatedly, thus required inclined-plane is all processed to the two ends of each root packaging bar product.
In diagram, the cutter 5 that left cylinder 2 drives is in shear action state, and the cutter 5 that right cylinder 6 drives is in non-shear operating state.In practical application, two cutters 5 are synchronization actions.
