[0002] The environmentally friendly packaging film slitting and rewinding device is an automated equipment used to slit wide environmentally friendly films into specific widths and rewind them.
[0003] Existing environmentally friendly packaging film slitting and winding devices typically use a winding mechanism to move the film, slitting it with a cutter during movement, before winding it up. However, the cutter cannot automatically adjust its position according to the slitting needs, requiring operators to remove and reinstall it in a preset position, resulting in poor performance. Furthermore, during winding, the film remains in close contact with the winding roller, making it inconvenient to remove after winding, further complicating the process. Therefore, we propose a fully automatic environmentally friendly packaging film slitting and winding device. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0028] Reference Figures 1-5 A fully automatic environmentally friendly packaging film slitting and rewinding device includes a base 1, a U-shaped frame 3 installed on the top of the base 1, a control cabinet 19 installed on the side of the U-shaped frame 3, and a controller inside the control cabinet 19, which is either a control motherboard or a PLC logic controller.
[0029] like Figure 2and Figure 3 As shown, a rotating roller 8 is rotatably connected inside the U-shaped frame 3, and a horizontal plate 5 is installed at the top inside the U-shaped frame 3. A second cutter 28 is installed at the bottom of the horizontal plate 5. Several first cutters 7 are provided on both sides of the second cutter 28, and the bottom of the first cutter 7 and the second cutter 28 are in clearance fit with the top of the rotating roller 8. In actual use, the environmentally friendly packaging film will pass through the rotating roller 8, so the first cutter 7 and the second cutter 28 will cut the packaging film.
[0030] like Figure 2 and Figure 3 As shown, strip grooves 22 are provided on both sides of the top of the horizontal plate 5. Each first cutter 7 is equipped with a sliding block 27 on its top. The top of each sliding block 27 extends into the corresponding strip groove 22. The tops of the two outermost sliding blocks 27 are connected to adjusting rods 25 through hinge seats. The other end of each adjusting rod 25 is fixed to the bottom of the fixed seat 26 through the hinge seat. The top of the fixed seat 26 is connected to the U-shaped frame 3 through a telescopic mechanism 4. The telescopic mechanism 4 is one of an electric push rod, a cylinder, or a hydraulic rod. In actual use, the telescopic mechanism 4 will drive the fixed seat 26 to move up and down. While moving, it will control the tilt angle of the two adjusting rods 25, thereby controlling the sliding blocks 27 to move horizontally along the strip groove 22.
[0031] like Figure 3 As shown, several connecting rods 6 are rotatably connected to both sides of the second cutter 28 and each first cutter 7. The ends of adjacent connecting rods 6 are stacked and rotatably connected by a pivot. When the sliding blocks 27 on both sides move horizontally under the action of the adjusting rod 25, the connecting rods 6 will rotate with the movement of the sliding blocks 27, which can drive the other sliding blocks 27 to move. In this way, the distance between two adjacent first cutters 7 and between the first cutter 7 and the second cutter 28 can be adjusted as needed, and the packaging film can be cut according to the cutting requirements.
[0032] It should be noted that, as Figure 3 As shown, each strip groove 22 is equipped with a limiting rod 24 inside, and each limiting rod 24 slides through the corresponding sliding block 27. The limiting rod 24 can guide and limit the sliding block 27, and the water droplet sliding block 27 remains stable.
[0033] like Figure 1 and Figure 2 As shown, a vertical plate 15 is also installed on the top of the base 1. Several winding rollers 17 are rotatably connected to one side of the vertical plate 15, and the slit packaging film can be wound onto the winding rollers 17.
[0034] like Figure 1 and Figure 2As shown, one end of the take-up roller 17 passes through the upright plate 15 and is connected to the drive mechanism. The drive mechanism includes a second mounting plate 20 fixed to one side of the top of the upright plate 15. A drive motor 21 is mounted on the side of the second mounting plate 20. The output shaft of the drive motor 21 is connected to a second synchronous pulley 16. Each end of the take-up roller 17 is equipped with a first synchronous pulley 14. Two adjacent first synchronous pulleys 14 are connected by a synchronous belt, and one of the first synchronous pulleys 14 is connected to the second synchronous pulley 16 by a synchronous belt. In the actual schematic process, the drive motor 21 is connected to the controller through a wire. In actual use, the drive motor 21 can synchronously drive the take-up roller 17 to rotate with the cooperation of the first synchronous pulley 14 and the second synchronous pulley 16 to take up the slit packaging film.
[0035] like Figure 2 and Figure 4 As shown, each take-up roller 17 is hollow, and each take-up roller 17 has several through slots 23 on its side. Each take-up roller 17 has several strip support plates 18 inside, and one end of each strip support plate 18 passes through the corresponding through slot 23. The strip support plates 18 can support and press the wrapped packaging film, so that the packaging film will not rotate relative to the take-up roller 17 when it is being wound up.
[0036] like Figure 4 As shown, an airbag 30 is installed inside the take-up roller 17. Each strip support plate 18 is equipped with a strip connecting plate 31 near one end of the airbag 30. The side of the strip connecting plate 31 is fixed to the outer surface of the airbag 30. The airbag 30 can push the strip connecting plate 31 so that one end of the strip support plate 18 extends out of the through groove 23 and presses the packaging film together.
[0037] like Figure 1 As shown, a first mounting plate 11 is installed on one side of the top of the upright plate 15. An air pump 9 is installed on the top of the first mounting plate 11. The air outlet of the air pump 9 is connected to an air supply pipe 12. Several diversion pipes 13 are installed on the side of the air supply pipe 12. The other end of each diversion pipe 13 is connected to the end of the corresponding take-up roller 17 through a rotating joint. The end of each diversion pipe 13 is connected to the inside of the airbag 30. The air pump 9 is connected to the controller through a wire. In actual use, the air pump 9 can deliver external air through the air supply pipe 12 to the diversion pipe 13, and finally deliver it to the airbag 30 through the diversion pipe 13, inflating the airbag 30 and causing one end of the strip support plate 18 to move out of the through groove 23.
[0038] It should be noted that, as Figure 1As shown, a valve 10 is installed at one end of the gas supply pipe 12. The valve 10 is connected to the controller via a wire. After the gas supply pump 9 fills the airbag 30 with air, the operator can close the gas supply pump 9 and the valve 10 through the controller, so that the gas in the airbag 30 will not leak from the gas supply pipe 12.
[0039] It should be noted that, as Figure 5 As shown, both ends of the strip connecting plate 31 extend to the side of the strip support plate 18, and springs 29 are installed at both ends of the top of the strip connecting plate 31. The other end of the spring 29 is fixed to the inner wall of the take-up roller 17. After the winding is completed, the operator opens the valve 10 through the controller. Under the elastic force of the spring 29, the air bag 30 of the strip connecting plate 31 is squeezed, and the gas in the air bag 30 is discharged through the air pipe 12. At this time, the air bag 30 is deflated, and the spring 29 will drive the strip connecting plate 31 to move towards the inside of the take-up roller 17, so that the end of the strip support plate 18 retracts into the through groove 23. This makes it easy to remove the wound packaging film from the take-up roller 17, making material removal convenient.
[0040] Specifically, when using this utility model, the operator controls the telescopic mechanism 4 to work. When the telescopic mechanism 4 extends and retracts, it drives the fixed seat 26 to move up and down. When the fixed seat 26 moves up and down, it drives the two adjusting rods 25 to rotate simultaneously. When the adjusting rods 25 rotate, they push the sliding blocks 27 on both sides to move along the strip groove 22. Under the action of the connecting rod 6, they can drive the first cutter 7 to move horizontally simultaneously. In this way, the distance between the first cutters 7 and the distance between the first cutter 7 and the second cutter 28 can be adjusted according to the cutting needs, thereby improving the usage effect.
[0041] The operator controls the controller to open valve 10 and simultaneously controls the air pump 9 to work. The air pump 9 delivers outside air through the air pipe 12 to the diversion pipe 13, and finally delivers it to the air bladder 30 in the take-up roller 17, inflating the air bladder 30. The air bladder 30 pushes the strip connecting plate 31 to move, causing one end of the strip support plate 18 to move out of the through groove 23. Then the operator turns off the air pump 9 and closes valve 10. After that, the operator passes the packaging film to be cut through the guide roller 2 and the rotating roller 8, and after being cut by the first cutter 7 and the second cutter 28, it is wound onto the corresponding take-up roller 17, so that when the packaging film is wound onto the take-up roller 17, it will be tightly pressed against the end of the strip support plate 18.
[0042] Then, the drive motor 21 is controlled to work. Under the action of the first synchronous pulley 14 and the second synchronous pulley 16, the drive motor 21 can synchronously drive the winding roller 17 to rotate and wind up the packaging film. After winding is completed, the operator controls the valve 10 to open. Under the thrust of the spring 29, the strip connecting plate 31 can be pushed to move into the winding roller 17. The strip connecting plate 31 flattens the air bag 30. At the same time, the end of the strip support plate 18 will move into the through groove 23. At this time, the operator can remove the wound packaging film from one end of the winding roller 17, which is convenient for material removal.
[0043] Furthermore, such as Figure 1 and Figure 2 As shown, guide rollers 2 are rotatably connected to both sides of the U-shaped frame 3. The guide rollers 2 are located below the rotating roller 8. The guide rollers 2 can guide the packaging film so that after the packaging film is cut, it can pass through the guide rollers 2 and be wound onto the winding roller 17. During winding, the packaging film will remain stable.
[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
