The connecting base 20 is fixedly arranged on the fixed mounting base 10, a through hole 21 is formed in the center of the connecting base 20, the sliding rod 30 penetrates through the through hole 21, the gear cutter head 40 is arranged at the first end of the sliding rod 30, and an elastic body 50 is arranged between the second end of the sliding rod 30 and the connecting base 20. Thus, the elastic restoring force of the elastic body 50 is used to pull the sliding rod 30 all the time to press the packaging film 100, and the packaging film moves to drive the gear cutter head 40 to rotate together, so that the surface of the packaging film can be scratched with a tear.

Wherein, the elastic body 50 is a tension spring or a rubber band. The rubber band is low in cost and easy to obtain, so that the rubber band is preferably used. Preferably, the second end of the sliding rod 30 is provided with a first lug 31, the connecting socket 20 is provided with a second lug 22 and a third lug 23 at intervals, the distance between the first lug 31 and the second lug 22 is L1, and the distance between the first lug 31 and the third lug 23 is L2, L2> L1. By providing two sets of L1 and L2 of different lengths, the elastic restoring force of the elastic body 50 can be adjusted, thereby controlling the pressure of the gear cutter head 40.

The fixed mounting seat 10 comprises a cross beam 11 fixedly arranged on the rack, a vertical rod 12 and an inclined rod 13 fixed on the cross beam 11, a tripod is formed by the cross beam 11, the vertical rod 12 and the inclined rod 13, and the connecting seat 20 is welded on the tripod. Since the tripod is stable and simple in structure, the supporting link base 20 is stable without being distorted.

As shown in fig. 1, the through hole 21 of the connecting seat 20 is a circular hole, the sliding rod 30 is a circular rod, and the diameter of the sliding rod 30 is smaller than the inner diameter of the circular hole, so that the sliding rod 30 can slide in the circular hole. The gear cutter head 40 includes a shaft core 41, a first clamping piece 42, a second clamping piece 43, and a gear cutter 44, and the gear cutter 44 is integrally sandwiched between the first clamping piece 42 and the second clamping piece 43, and is rotatably mounted on the shaft core 41. The provision of the first jaw 42 and the second jaw 43 allows the gear cutter 44 to be easily installed, and the gear cutter 44 can be made thin, thereby reducing costs. As shown in fig. 2, the gear blade 44 includes a main body 441 and a blade 442, the blade 442 is disposed on the outer circumference of the main body 441, and the blade 442 is pointed and the blade 442 is divided into a plurality of discontinuous peaks.

The utility model discloses a wrapping bag tearing notch shaping gear sword structure's application method as follows: the sliding rod 30 is inserted into the through hole 21 of the coupling holder 20 and then a rubber band is put on so that the gear bit 40 is pressed against the packing film. The machine is then started and the machine drags the packaging film to be conveyed, during which the packaging film is rolled with the toothed wheel bits 40 of the surface, with the rotating roller 101 acting as a carrier, to score the tear.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
