Technical Field

[0001] This utility model relates to a packaging film winding and slitting device, belonging to the technical field of packaging production equipment. Background Technology

[0002] Currently, packaging films are typically produced with a fixed width after processing. However, the width of various packaging film rolls on the market varies depending on different usage requirements. Therefore, it is necessary to adjust the slitting position of the packaging film before winding it up to obtain packaging film rolls of various widths.

[0003] However, in existing technologies, packaging film is transported through multiple different guide rollers during the winding process. During the slitting position adjustment unit process, the packaging film may shift to either side on the guide rollers, causing one side of the packaging film exiting the slitting position adjustment unit to be skewed, which seriously affects the quality of the packaging film.

The packaging film 6 enters the guide roller conveying mechanism 5 through the U-shaped groove of the web-alignment sensor 2, and is then conveyed by the guide roller conveying mechanism 5 from the feed end at the bottom of the equipment frame 1 to the discharge end at the top of the equipment frame 1. During the conveying process, the cutting mechanism 4 cuts the packaging film 6, and the web-alignment sensor 2 continuously monitors whether the packaging film 6 is shifting to either side during the cutting process.

[0017] The web-correction mechanism 3 includes a guide component, a servo web-correction component, and a cutting position adjustment component. The guide component is fixed on the equipment frame 1.

The cutting position adjustment component is used to drive the servo web-correction component and the cutter mechanism 4 to move together on the guide component. First, according to the cutting requirements, such as splitting the packaging film 6 into 50 / 50 or 30 / 70 proportions, the cutting position adjustment component adjusts the position of the cutter mechanism 4 on the guide component. After the cutting position is adjusted, the equipment can be started to cut the packaging film 6. Then, during the cutting process, if the web-correction sensor 2 detects that the packaging film 6 has shifted to either side, for example, shifting a certain distance to the left, the servo web-correction component drives the cutter mechanism 4 to move a corresponding distance to the left, ensuring that the side of the packaging film 6 that has been cut is always a straight line.

The slitting adjustment handwheel 341 is connected to the slitting adjustment lead screw 344 via the cornering device 343. The slitting adjustment lead screw 344 is screwed to the driver seat 32. Rotating the handwheel will cause the slitting adjustment lead screw 344 to rotate via the cornering device 343. The slitting adjustment lead screw 344 then drives the driver seat 32 of the servo correction assembly and the tool mechanism 4 to move on the two guide rods 31, thereby adjusting the slitting position. During the slitting process, the servo correction assembly further fine-tunes and corrects the slitting position.

[0021] like Figure 2 , 3 As shown, the cutting tool mechanism 4 in this embodiment includes a tool holder 41, a cutting tool fixing plate 42, a cutting tool clamping seat 43, and a blade 44.
