[0031] As Figures 1 - 4 shown, an ultrasonic cutting tool for a composite plastic packaging tear opening provided in this embodiment includes:

[0032] An ultrasonic generator 34; Exemplarily, the ultrasonic generator 34 converts the power current of 110VAC or 220VAC into a high-frequency high-voltage electrical signal, and the ultrasonic generator 34 is connected to the power supply through a wire to be energized.

[0033] An ultrasonic converter 31, the ultrasonic converter 31 is connected to an ultrasonic generator 34 through a wire; the ultrasonic transducer utilizes the high-frequency electrical signal from the ultrasonic generator 34 and converts it into a linear mechanical motion. This conversion is carried out by using a piezoelectric ceramic disk, which expands when a voltage is applied.

[0034] An ultrasonic booster 32, the ultrasonic booster 32 is connected to the ultrasonic converter 31; the ultrasonic booster 32 is a tunable component that can mechanically adjust the displacement of the linear vibration of the ultrasonic transducer to the level required for a specific application to produce optimal cutting performance.

[0035] A rotating motor 33, the rotating motor 33 is connected to the ultrasonic booster 32; the rotation speed of the rotating motor 33 is consistent with the conveying speed of the composite plastic packaging film 1.

[0036] A blade 35, the blade 35 is connected to the output shaft of the rotating motor 33, and notches 351 are evenly arranged on the edge of the blade 35.

[0037] The blade 35 is disc-shaped, and the edge of the blade 35 is not a sharp cutting edge, but is similar to a grinding disc.

[0038] The extending direction of the output shaft of the rotating motor 33 is perpendicular to the extending direction of the ultrasonic booster 32.

[0039] It also includes a frame 2, and the ultrasonic converter 31 is fixed on the frame 2. Specifically, the frame 2 is a conveying frame for conveying the composite plastic packaging film 1, and a roller 4 is rotatably arranged on the conveying frame. The roller 4 conveys the composite plastic packaging film 1. By fixing the ultrasonic cutting tool 3 on the frame 2, the slitting process of the conveyed composite plastic packaging film 1 is realized.

[0040] The ultrasonic booster 32 is fixedly connected to the rotating motor 33 through a connecting member 5. Specifically, the connecting member 5 can be existing clamping members such as snap rings and clamps. By using the connecting member 5 to fix the rotating motor 33 on the ultrasonic booster 32, it can not only make the blade 35 rotate with the output shaft of the rotating motor 33, but also carry out the slitting process on the conveyed composite plastic packaging film 1 through the high-frequency vibration transmitted by the ultrasonic booster 32, so that the processed slit is a discontinuous slit (hollow hole).

[0041] The ultrasonic booster 32 includes a rod portion 321 and a plate portion 322. One end of the rod portion 321 is fixedly connected to the plate portion 322, and the other end of the rod portion 321 is fixedly connected to the ultrasonic converter 31; the plate portion 322 is fixedly connected to the rotating motor 33 through a connecting member 5.

[0042] The connecting member 5 includes a clamping plate 51, a connecting bolt 52 and a connecting nut 53. The clamping plate 51 and the plate portion 322 are respectively located on both sides of the fixed end of the rotating motor 33. The clamping plate 51 and the plate portion 322 are connected by the connecting bolt 52, and the connecting nut 53 is connected to the connecting bolt 52. By cooperating the connecting bolt 52 with the connecting nut 53, the clamping plate 51 and the plate portion 322 clamp the rotating motor 33 in a tensile manner, ensuring that the rotating motor 33 is fixed between the clamping plate 51 and the plate portion 322.

[0043] Before use, ultrasonic cutting tools 3 for processing the number of tear openings are arranged side by side on the frame 2. For example, in the solution of this embodiment, four ultrasonic cutting tools 3 are arranged side by side on the frame 2, so that the edge of the blade 35 of the ultrasonic cutting tool 3 corresponds to the position of the tear opening of the composite plastic packaging film 1. The ultrasonic generator 34 is connected to the power supply, and the rotating motor 33 is connected to the power supply. The conveying mechanism of the composite plastic packaging film 1 is started to convey the composite plastic packaging film 1, and the blade 35 starts to process the tear opening of the composite plastic packaging film 1. Since the rotation speed of the rotating motor 33 is consistent with the conveying speed of the composite plastic packaging film 1, during the tear opening processing, the notch 351 of the blade 35 will not contact the composite plastic packaging film 1, and the part of the blade 35 without the notch 351 contacts the composite plastic packaging film 1, so that the composite plastic packaging film 1 forms discontinuous hollow holes (tear openings); since the blade 35 is disc-shaped, it cannot cut the composite plastic packaging film 1 even if it is driven by the rotating motor 33. The cutting function mainly relies on the high-frequency vibration formed by ultrasonic conversion. The high-frequency vibration transfers mechanical energy to the composite plastic packaging film 1 to achieve cutting. Therefore, the tear openings on the composite plastic packaging film 1 can achieve high cleanliness, with the advantages of smooth, firm cut edges, accurate cutting edges, no deformation, no warping, no fuzzing, no drawing, no wrinkling, etc.
