[0002] POF heat shrink film is a material widely used in the packaging industry. It has excellent transparency, strength and shrinkage. Antistatic agents are added to POF heat shrink film to prevent static electricity accumulation. It is suitable for the packaging of electronic products. After the POF heat shrink film is formed, it needs to be trimmed using a trimming device to cut it into the appropriate size.

[0003] Patent publication number CN215037886U discloses a POF heat shrink film cutting device, which includes a film cutting device body, a rubber anti-slip strip installed at the lower end of the film cutting device body, and two rubber anti-slip strips are provided. A control panel is installed on one side of the film cutting device body, and four control buttons are installed on one side of the control panel. A transport transmission shaft is installed at the upper end of the film cutting device body.

[0004] In the above technology, the film can be placed on a transport anti-skid track when cutting the film, which effectively avoids the displacement of the film position during the cutting process.

The pressing plate 15 can be used to press one side of the POF heat shrink film so that the POF heat shrink film can stay stably at the bottom of the cutting knife 2.

[0025] Example 2:

[0026] Based on the first embodiment, Figure 1 and Figure 4 As shown, two clips 16 are provided on the top of the pressing plate 15, and one end of the two clips 16 is respectively engaged with the inside of the two clip holes 14, and the two restraining rings 9 are respectively movable at the two end portions of the tensioning cylinder 8, and the tensioning cylinder 8 is fixedly sleeved with one end of the roller 7. The roller 7 can rotate at one end of the support rod 6, thereby driving the tensioning cylinder 8 to rotate, so that the POF heat shrink film can be continuously pulled according to the required cutting length, so that one side of it moves toward the position of the pressing table 13, and the bottom surface of the POF heat shrink film is tightly fitted with the surface of the pressing table 13. One end of the two clips 16 is aligned with the corresponding clip holes 14, and the two are engaged, so that the pressing table 13 and the pressing plate 15 can be limited and fixed.

[0027] Working principle: POF heat shrink film is a material widely used in the packaging industry. It has excellent transparency, strength and shrinkage. Antistatic agent is added to POF heat shrink film to prevent static electricity accumulation. It is suitable for the packaging of electronic products. After the POF heat shrink film is formed, it needs to be trimmed using a trimming device to cut it into a suitable size. First, the formed POF heat shrink film is wrapped and rolled on the outer surface of the tensioning cylinder 8. The surface of the tensioning cylinder 8 is coated with an antistatic coating, which can effectively reduce static electricity accumulation. The two binding rings 9 can move left and right at both ends of the tensioning cylinder 8. The two binding rings 9 are movable, driving the positioning ring 10 to move at one end of the tensioning cylinder 8, so that the binding ring 9 contacts the two ends of the POF heat shrink film. The positioning of the tensioning cylinder 8 and the binding ring 9 can avoid position deviation of the POF heat shrink film during stretching and cutting, thereby improving the quality of subsequent trimming. The pressing plate 15 can be used to press one side of the POF heat shrink film so that the POF heat shrink film stays steadily on the bottom of the cutting knife 2. A small amount of aluminum powder is added to the POF heat shrink film itself, which can form a conductive network, reduce the resistance of the film, and thus improve the antistatic performance. The roller 7 can rotate at one end of the support rod 6, thereby driving the tensioning cylinder 8 to rotate, so that the POF heat shrink film can be continuously pulled according to the required cutting length, so that one side of the POF heat shrink film can be moved toward the position of the pressing plate 13. The bottom surface of the POF heat shrink film is tightly fitted with the surface of the pressing plate 13, and one end of the two clips 16 is aligned with the corresponding clip holes 14. The two are engaged, so that the pressing plate 13 and the pressing plate 15 can be limited and fixed. The pressing plate 15 can press one side of the POF heat shrink film, and then the POF heat shrink film can be cut normally.
