A kind of packing bar end chamfer cutter cutting mechanism
Technical field
The present invention relates to a kind of cutter, especially relate to a kind of packing bar end chamfer cutter cutting mechanism.
Background technology
The packing bar of using in packaging industry, often need to process the inclined-plane of end, when packing in a three-dimensional packing bight, the perfections docking of three packing bars, 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 packing bar, cause the workload of shearing large, workman's labour intensity is higher.
In addition because cutter of the prior art is that cross section is the sheet of yi word pattern, it is being carried out in the guiding of shear direction, the skew of as easy as rolling off a log generation direction, thus affect shear effect.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of simple in structurely, operation easily, and easily guarantees the packing 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 packing bar end chamfer cutter cutting mechanism, be arranged in the frame of described cutter, described cutting mechanism is provided with two cutters that are respectively used to shear packing 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 all towards this packing bar clipped position, be obliquely installed, form V character form 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 being hinged in frame separately, connecting lever swings around pin joint under the driving of cylinder separately, with band cutter, along cutter gathering sill, move back and forth, thereby to shearing through the packing bar of packing bar clipped position.
Described connecting lever is L-shaped, and its corner and frame are hinged, and its two ends are hinged with cutter and cylinder respectively.
The cross section of described cutter is inverted V-shaped, and the shape of its upper and lower surface matches with the shape of the upper and lower internal face of cutter gathering sill respectively.
The invention has the beneficial effects as follows:
Adopt cylinder for shear action provides power, greatly alleviated workman's labour intensity; The structure of cutter is more reasonable, and not only solve cutter in guiding and be easy to the problem of laterally sliding, and also convenient processing, and more easily guarantee to shear the accuracy of result, guarantee the required precision of shear product.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to further concrete detailed explanation.
As shown in the figure, a kind of packing bar end chamfer cutter cutting mechanism, be arranged in the frame 1 of described cutter, described cutting mechanism is provided with two cutters 5 that are respectively used to shear packing 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 all towards this packing bar clipped position, be obliquely installed, form V character form 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 being hinged in frame 1 separately, connecting lever 3 swings around pin joint (i.e. bearing pin 4 in diagram) under the driving of cylinder separately, with band cutter 5, along cutter gathering sill, move back and forth, thereby to being that packing bar between pilot unit 7 belows and chopping block 8 is sheared through packing bar clipped position.
Described connecting lever 3 is L-shaped, and its corner and frame 1 are hinged, and its two ends are hinged with cutter 5 and cylinder respectively.
The cross section of described cutter 5 is inverted V-shaped, and the shape of its upper and lower surface matches with the shape of the upper and lower internal face of cutter gathering sill respectively.
Compact in order to guarantee that enough intensity can make structure display obtain again, described connecting lever 3 adopts tabular, and described tabular connecting lever and frame 1 be arranged in parallel.
Described cutter 5 cross sections are inverted v-shaped, such structure can prevent that in using the process leading with the pilot unit with the corresponding cutter gathering sill of the shape of tool cutter 5 from sliding along cutter 5 widths, thereby the accuracy that guarantees shear action, finally guarantees the required precision of product.
Use the present invention can original packaging bar be cut into respectively with two of shearing inclined-plane simultaneously, original packaging bar advances to behind needed fixed length position continuously, cutting mechanism is sheared again simultaneously, so repeatedly, thus the two ends of each root packing bar product are all processed to needed inclined-plane.
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 action state.In practical application, two cutters 5 are synchronization actions.
