Description

Technical Field

[0001] The utility model relates to the technical field of film slitting devices, in particular to an upper cutting knife mechanism with a dust removal function. Background Art

[0002] After the conductive film is produced, it needs to be slit so that the width of the film meets the product requirements. The existing slitting mechanism is to install the slitting tool on the knife shaft, and a rotary motor is set at both ends of the knife shaft to drive the knife shaft to rotate, thereby driving the knife to rotate and cut the film.

[0033] By embedding the upper end of the upper cutter 2 in the upper dust removal cavity 3, this embodiment can prevent the dust generated during the cutting process from adhering to the periphery of the cutter and the cutting point of the film A, which not only affects the cutting quality of the film A, but also causes the two sides of the rolled film A to be thicker in the width direction, thereby affecting the flatness of the rolled film A roll.

[0034] Figure 2 FIG. 1 is a partial schematic diagram of an upper cutter mechanism with a dust removal function according to an embodiment of the present utility model. Figure 2 As shown, the upper cutter 2 mechanism also includes: a lower dust removal chamber 4 and a connecting plate 5; the lower dust removal chamber 4 is connected to the upper dust removal chamber 3 through the connecting plate 5, and the lower dust removal chamber 4 is fixed below the upper cutter 2; the upper end of the lower dust removal chamber 4 has a second strip hole 41, and the lower end of the lower dust removal chamber 4 has a third strip hole 42, and the bottom end of the upper cutter 2 passes through the lower dust removal chamber 4 through the second strip hole 41 and passes through the third strip hole 42. In this embodiment, the lower dust removal chamber 4 has two strip holes, and the upper strip hole (i.e., the second strip hole 41) cooperates with the lower end of the upper cutter 2, and the lower end of the upper cutter 2 can be embedded in the chamber; the length of the lower strip hole (i.e., the third strip hole 42) is smaller than the length of the upper strip hole, and is used for the smallest end of the upper cutter 2 to pass through.
