The invention discloses a
score type splitting structure of a splitting
machine and an operation method. The structure comprises a tool support, wherein two tool rest wall panels which are arranged inparallel are arranged on the tool support; a two-sided dovetail groove block is fixedly connected with a position between the tool rest wall panels; the two-sided dovetail groove block is fixedly connected with a pneumatic
score cutter; the pneumatic
score cutter presses against a coiled material aligned to the surface of a dead knife roll and arranged on the dead knife roll during operation to perform splitting. The structure has the advantages that firstly, the pneumatic score cutter directly presses against the dead knife roll to perform splitting, even thick glue can be
cut apart, and a cutter cleaning mechanism is provided, so that glue is not easy to stick the cutter; secondly, the structure adopts a two-sided dovetail groove design, the two-sided dovetail groove adopts a 42-degreeincluded angle design, and the pneumatic score cutter can not only
cut the inlet point of the coiled material, but also
cut the outlet point of the coiled material according to different technical requirements of
adhesive tape materials; thirdly, the dead knife roll adopts a special
technical design,
tungsten carbide is plated on the surface of the dead knife roll, and tracks are not left on the surface of the dead knife roll while splitting is realized; fourthly, compared with the traditional splitting mode, the structure is convenient, and
cutting can be singly performed.
