Film cutting mechanism with slitter edge slitting function

Abstract

The invention discloses a film cutting mechanism with a slitter edge slitting function. The film cutting mechanism with the slitter edge slitting function comprises a rack, a bearing groove, a film cutting assembly and a pushing assembly, wherein the film cutting assembly comprises an annular first base, multiple mounting rods and an annular first cutter; the mounting rods are arranged around thecircumferential direction of the first base at intervals and extend in the radial direction of the first base; the annular first cutter is mounted between the multiple mounting rods; a packaging coverfilm can pass through the first cutter in a matched mode and is annularly cut into a packaging cover and a slitter edge; the film cutting assembly further comprises multiple second cutters which arearranged on the outer circumferential face of the first cutter by surrounding the circumferential direction of the first cutter at intervals and used for slitting the slitter edge; and the multiple second cutters correspond to the multiple mounting rods one to one and are located on the sides, close to the bearing groove, of the mounting rods. According to the film cutting mechanism provided by the invention, through the arrangement of the second cutters, the overall annular slitter edge obtained after annular cutting can be cut into smaller slitter edges again, so that blocking of the mounting rods can be avoided, smooth output is achieved, and accumulating and winding of the slitter edges on the peripheral side of the cutters are avoided.

Description

technical field [0001] The invention relates to a film cutting mechanism with waste edge cutting function. Background technique [0002] Film cutting is a process used to ring-cut the packaging cover film to obtain the packaging cover. At present, for small batches of film cutting, it is usually realized by a push film cutting machine. First, the large-sized packaging cover film is divided into multiple small-sized packaging covers. Each small-sized packaging cover film contains a package cover, and then arrange the multiple small-sized packaging cover films in the bearing groove of the push-type film cutter in sequence, and push the multiple packaging cover films into the ring-shaped cutter through the power cylinder to realize the ring shape of the packaging cover. cut. [0003] However, after ring-cutting the packaging cover film, the waste edge on the peripheral side of the packaging cover still forms an integral ring shape, and since the ring cutter needs to be fixed ...

Problems solved by technology

[0003] However, after ring-cutting the packaging cover film, the waste edge on the peripheral side of the packaging cover still forms an integral ring shape, and since the ring cutter needs to be fixed by the base and the mounting rod, one end of the mounting rod must abut against the On the cutting knife, this leads to the fact that the overall waste edge after ring cutting cannot be smoothly output under the obstruction of the installation rod, and all accumulate and wind around the cutting knife, which greatly affects the subsequent production process.
