[0037] Embodiment

[0038] As Figures 1-2 shown, the high polymer plastic packaging sheet 10 cutting and winding device provided by the present application comprises: a guide roller mechanism 1, a winding roller mechanism 2, and at least one cutting mechanism 3. In the present embodiment, two cutting mechanisms 3 are provided. The winding roller mechanism 2, the guide roller mechanism 1 and the cutting mechanism 3 are arranged on the same mounting platform 9.

[0039] The winding roller mechanism 2 is arranged apart from the guide roller mechanism 1 and is used for winding the high polymer plastic packaging sheet 10. After forming, the high polymer plastic packaging sheet 10 is sent into the winding roller mechanism 2 through the guide roller mechanism 1 and is wound by the winding roller mechanism 2.

[0040] The cutting mechanism 3 is arranged between the guide roller mechanism 1 and the winding roller mechanism 2. A plurality of cutting mechanisms 3 are arranged in sequence along the advancing direction of the high polymer plastic packaging sheet 10. The cutting mechanism 3 comprises a driving unit 301 and a cutting unit 302 arranged on the output end of the driving unit 301. The driving unit 301 drives the cutting unit 302 to move along the direction perpendicular to the advancing direction of the high polymer plastic packaging sheet 10, so as to adjust the position of the cutting unit 302 in contact with the high polymer plastic packaging sheet 10.

[0041] The cutting mechanism 3 arranged between the guide roller mechanism 1 and the winding roller mechanism 2 can directly cut the large-area high polymer plastic packaging sheet 10 to be wound, so that the size of the wound roll can be directly used, and the driving unit 301 can drive the cutting unit 302 to adjust along the vertical film advancing direction, thereby adjusting the cutting position and accurately adjusting the different winding sizes. In addition, the cutting mechanism 3 can be provided with a plurality of cutting units 302, which can simultaneously cut the high polymer plastic packaging sheet 10 to form a plurality of film rolls with different sizes.

[0042] The cutting unit 302 comprises a lifting cylinder 3021 and a cutter holder 3022, wherein the lifting cylinder 3021 can be realized by a pneumatic cylinder, a hydraulic cylinder or an electric push rod, etc., the lifting cylinder 3021 is installed on the output end of the driving unit 301, the output end of the lifting cylinder 3021 is arranged upward, the cutter holder 3022 is installed on the output end of the lifting cylinder 3021, and a cutting blade 3023 is rotatably connected to the cutter holder 3022. The lifting cylinder 3021 can lift the cutter holder 3022 up and down, and the cutting blade 3023 on the cutter holder 3022 can selectively contact the high polymer plastic packaging sheet 10 passing above to cut the high polymer plastic packaging sheet 10.

[0043] By arranging the lifting cylinder 3021, when the cutting position needs to be adjusted, the cutter holder 3022 and the cutting blade 3023 can be lowered to not contact the high polymer plastic packaging sheet 10 above. When the driving device adjusts the lifting cylinder 3021 and the cutter holder 3022 to the appropriate position, the lifting cylinder 3021 lifts the cutter holder 3022 again, so that the cutting blade 3023 on the cutter holder 3022 contacts the high polymer plastic packaging sheet 10 above.

[0044] In order to better cut the cutting blade 3023, a guide mechanism 4 cooperating with the cutting blade 3023 is arranged, the guide mechanism 4 is arranged above the cutting unit 302 and spaced from the cutting blade 3023, and the guide mechanism 4 and the cutting blade 3023 are clamped on the upper and lower surfaces of the high polymer plastic packaging sheet 10. Through the guide mechanism 4 above, on the one hand, the guide mechanism 4 guides the high polymer plastic packaging sheet 10, and on the other hand, the guide mechanism 4 and the cutting blade 3023 clamp the high polymer plastic packaging sheet 10, so that the cutting is better and easier.

[0045] Specifically, the guide mechanism 4 comprises two guide rollers 5, which are arranged in the advancing direction of the high polymer plastic packaging sheet 10 and located on both sides of the cutting blade 3023, respectively. When the lifting cylinder 3021 lifts the cutter holder 3022 to the appropriate position, the surface of the guide roller 5 cooperates with the cutting edge gap of the cutting blade 3023.

[0046] In this embodiment, the polymer plastic packaging sheet 10 at the guide roller mechanism 1 is not at the same height as the polymer plastic packaging sheet 10 at the cutting mechanism 3. In this embodiment, the polymer plastic packaging sheet 10 at the guide roller mechanism 1 is higher than the polymer plastic packaging sheet 10 at the cutting mechanism 3, so that the polymer plastic packaging sheet 10 is taut on the guide roller mechanism 1, facilitating cooperation with the cutting blade 3023 to complete cutting.

[0047] The cutting blade 3023 is a circular cutting blade 3023, which is rotationally connected to the blade holder 3022. The cutting blade 3023 has a cutting edge in contact with the polymer plastic packaging sheet 10. The cutting blade 3023 is circular, and the rolling cutting blade 3023 can better cut during movement of the polymer plastic packaging sheet 10.

[0048] In order to limit the lifting position of the lifting cylinder 3021, a limit plate 6 is arranged on the lifting cylinder 3021. The output end of the lifting cylinder 3021 penetrates the limit plate 6 and is connected with the blade holder 3022. The bottom of the blade holder 3022 is provided with at least two limit rods 7. The limit rods 7 penetrate the bottom of the limit plate 6 to form a limit ring 8. In this embodiment, the limit rods 7 are provided with four limit rods, which are respectively located at the four corners of the limit plate 6. The limit ring 8 at the bottom of the limit rod 7 abuts against the bottom of the limit plate 6 during lifting of the limit rod 7 with the blade holder 3022, thereby limiting the lifting limit position of the blade holder 3022 and avoiding collision between the cutting blade 3023 on the blade holder 3022 and the upper guide roller 5.

[0049] In this embodiment, the driving unit 301 can adopt various driving modules capable of driving the cutting unit 302 to move reciprocally, such as a linear module. In this embodiment, the driving unit 301 includes a lead screw mechanism 3011 and a driving cylinder 3012. The driving cylinder 3012 is driven by a driving motor to move the lead screw mechanism 3011.

[0050] The lead screw mechanism 3011 is arranged perpendicular to the movement direction of the polymer plastic packaging sheet 10. The cutting unit 302 is installed on a sliding table 3013 of the lead screw mechanism 3011. The output end of the driving cylinder 3012 is connected with one end of the lead screw mechanism 3011 to drive rotation of the lead screw mechanism 3011, thereby driving the sliding table 3013 to move reciprocally. The bottom of the sliding table 3013 passes through two tracks.

[0051] Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, but not limited to them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
