Description

Technical Field

[0001] The invention relates to the technical field of PE film processing and forming, in particular to a PE film casting molding processing and recycling integrated device. Background Art

[0002] PE film, or polyethylene film, is a plastic film made of polyethylene resin through an extrusion molding process. PE film has excellent chemical stability, water resistance, moisture resistance, electrical insulation and mechanical strength, and is widely used in packaging, agriculture, construction and other fields. PE film is usually produced by a tape casting process. In this process, the molten polyethylene resin is extruded onto a cooling roller, cooled and pulled to form a continuous film. In order to achieve efficient resource utilization and production continuity, modern PE film production lines are often also equipped with a recycling system for recycling scraps or waste generated during the production process, thus forming an integrated tape casting processing and recycling device.

[0003] When PE film is used as a packaging material, in order to adapt to the shape of the packaged object, a hollow design is generally made on the PE film. Because the molten PE may enter the hollow part during the production process due to trace gases or uneven mixing of raw materials, bubbles are easily formed inside the film. The presence of bubbles will destroy the continuity and uniformity of the PE film. When the PE film is subjected to external forces during winding, it is more likely to break or be damaged, thereby reducing its reliability as a packaging material. In addition, since the edges of the molded PE film are in a hollow state, it is easy to warp during the winding process. When the edge part is warped upward, the molded PE film will not fit tightly with the winding roller. The uneven edges of the PE film roll after winding not only affect the aesthetics, but may also affect subsequent processing steps such as cutting and printing, further increasing the difficulty of production.

Detailed implementation manners

[0031] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The following will refer to the drawings and combine with the embodiments to detail the present application.

[0032] In order to enable those skilled in the art to better understand the solution of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0033] Please refer to Figures 1 to 8, An integrated device for PE film casting forming processing and recycling, comprising: an equipment base 1, on which a feeding hopper 2 is arranged, on one side of the feeding hopper 2 an extrusion device 3 is arranged, on one side of the extrusion device 3 an extrusion die head 4 is arranged, on the equipment base 1 a roller assembly is arranged, and a formed PE film 9 is wound and attached to the roller assembly. Among them, the roller assembly is rotatably arranged on the equipment base 1, and the roller assembly includes a squeezing roller 5, a cooling roller 6, a winding roller 7 and a recycling roller 8. The squeezing roller 5 is arranged below the extrusion die head 4, the cooling roller 6 is arranged on one side of the squeezing roller 5, the winding roller 7 is arranged on the side of the swing mechanism 10 away from the cooling roller 6, and the recycling roller 8 is arranged on one side of the equipment base 1 above and close to the feeding hopper 2. PE particles enter the extrusion device 3 through the feeding hopper 2 and are melted and plasticized under the action of barrel heating and screw shearing. The melt forms a molten film by flat extrusion through the extrusion die head 4, and the molten film flows onto the surface of the quenching roller and is quickly solidified under the action of double-sided cooling water to achieve uniform crystallization. The cooled film is corona-treated to increase the surface energy, and then undergoes secondary heating and stretching through a recrystallization unit. Finally, it is wound into a finished film roll with a specified width and diameter by a winding machine. The waste edges generated by slitting are converted into pellet materials through a pressure cutting granulator, mixed with new materials in proportion, and re-fed into the extruder to form a "production - recycling - reuse" closed-loop system.

[0034] Please refer to Figures 1 to 8 , An integrated device for PE film casting forming processing and recycling further includes: a swing mechanism 10, the swing mechanism 10 is arranged on one side of one of the roller assemblies, the swing assembly includes a connecting rod 11 fixedly arranged on the equipment base 1, swing blocks 20 are symmetrically and rotatably connected to the connecting rod 11, and a swing plate 21 is fixedly connected to the swing blocks 20. The swing mechanism 10 is used to discharge the bubbles inside the formed PE film 9; the swing plate 21 is a component that directly contacts the PE film and applies a force. To ensure that when contacting the formed PE film 9 with a hollow design, it can provide a uniform and appropriate swinging force, which can effectively discharge the bubbles caused by the hollow design without damaging the film surface. This slight deformation and vibration can effectively break the relatively stable PE melt structure around the bubbles. The bubbles originally wrapped by the PE melt, under the action of the swinging force, the interfacial tension between it and the melt will be disturbed. When this disturbance reaches a certain degree, the bubbles will start to rise and finally burst on the surface or inside of the PE film, releasing the internal gas and discharging it through the hollow part of the formed PE film 9.

[0035] Please refer to Figures 1 to 8, a PE film casting forming, processing and recycling integrated device, further comprising: a film edge flattening mechanism 22, which is arranged on one of the roller assemblies. The film edge flattening mechanism 22 includes arc-shaped plates 34 symmetrically and movably arranged above the roller assembly. The film edge flattening mechanism 22 is used to extrude and flatten the edges of the formed PE film 9 to prevent it from curling. The film edge flattening mechanism 22 is arranged above the winding roller 7 of the device. The two arc-shaped plates 34 are symmetrically distributed on both sides above the winding roller 7 with the winding roller 7 as the center line. The bottom of the arc-shaped plate 34 fits the arc surface shape of the formed PE film 9 during the winding process, and its arc contour can fit the edge of the formed PE film 9, so as to accurately flatten the edge of the formed PE film 9 with edge hollowing, thereby preventing the formed PE film 9 from curling.

[0036] It should be noted that for details, please refer to Figures 1 to 2 and Figures 5 to 6 , the swing mechanism 10 further includes sleeve 12 symmetrically and fixedly arranged on the connecting rod 11. A connecting frame 13 is fixedly connected to the bottom of the sleeve 12 together. Sleeve 14 is fixedly arranged at the mutually close ends of the connecting rod 11. A driving shaft 15 is rotatably arranged in the middle of the sleeve 14. The driving shaft 15 is externally connected with an external drive. A fixed disk 16 is fixedly arranged at the top of the driving shaft 15. An eccentric shaft 17 is arranged through and eccentrically on the fixed disk 16. The outer surface of the eccentric shaft 17 is slidably connected with the fixed disk 16 up and down. A sleeve 18 is fixedly arranged at the top of the eccentric shaft 17. A fixed shaft 19 is arranged on the outer surface of the sleeve 18. Both ends of the fixed shaft 19 are fixedly connected with the swing block 20. The inner wall of the sleeve 18 slides on the outer surface of the fixed shaft 19.

[0037] By continuously rotating the driving shaft 15 to drive the fixed disk 16 above it to continuously rotate synchronously. While the fixed disk 16 is rotating, the eccentric shaft 17 eccentrically arranged on the fixed disk 16 will slide on the fixed shaft 19 through the sleeve 18. At this time, the swing blocks 20 at both ends of the fixed shaft 19 will continuously swing reciprocally on the connecting rod 11, thereby driving the swing plate 21 to swing reciprocally synchronously, and continuously reciprocally extruding the bubbles in the hollow PE forming die, which can effectively break the relatively stable PE melt structure around the bubbles. For the bubbles originally wrapped by the PE melt, under the action of the swinging force, the interfacial tension between it and the melt will be disturbed. When this disturbance reaches a certain degree, the bubbles will start to rise and finally burst on the surface or inside of the PE film, releasing the internal gas and discharging it through the hollow part of the PE forming die. The removal of bubbles helps to reduce the holes and defects in the PE film, making the PE film smoother and more uniform.

[0038] It is worth mentioning that for details, please refer to Figures 1 to 6 and Figures 7 to 8, the edge-aligning mechanism 22 further includes a fixed base plate 23 fixedly arranged between the equipment bases 1. Guide rails 24 are symmetrically arranged on the fixed base plate 23. The guide rails 24 are arranged in a staggered manner, and sliders 25 are slidably arranged on the guide rails 24. Fixed blocks 26 are fixedly arranged on the opposite surfaces of the sliders 25. Moving disks 27 are arranged on the sliders 25, and through grooves 28 are formed through the moving disks 27. Through the formed through grooves 28, the unwinding of the winding roller shaft 7 can be unobstructed. The moving disks 27 are slidably connected to the outer surface of the winding roller shaft 7 on the left and right through the arranged through grooves 28. A rotating shaft 29 is rotatably arranged in the middle of the top end of the fixed base plate 23. A first connecting rod 30 is fixedly arranged on the rotating shaft 29. First connecting pins 31 are fixedly arranged at both ends of the first connecting rod 30. Second connecting rods 32 are rotatably arranged on the outer surfaces of the first connecting pins 31. Second connecting pins 33 are arranged at the ends of the second connecting rods 32, and the second connecting pins 33 are fixedly arranged on the fixed blocks 26.

[0039] By rotating the rotating shaft 29 to drive the first connecting rod 30 fixedly arranged on its outer surface to rotate synchronously, and then driving the second connecting rod 32 to pull the fixed block 26 through the first connecting pin 31, the sliders 25 on the fixed block 26 move synchronously towards each other along the guide rails 24. The moving disks 27 fixed on the sliders 25 move synchronously towards the middle and fit on both sides of the formed PE film 9, limiting the formed PE film 9 to prevent deviation of the PE forming die during the winding process, ensuring that the formed PE film 9 with hollowing can be wound neatly and tightly on the winding roller, and improving the winding accuracy and efficiency.

[0040] It should be further noted that for details, please refer to Figure 7 and Figure 8 , the edge-aligning mechanism 22 further includes an arc-shaped plate two 35 fixedly arranged on the moving disk 27. A movable rod 36 is slidably arranged through the arc-shaped plate two 35. An elastic member 37 is sleeved on the movable rod 36. The bottom of the movable rod 36 is fixedly connected to the arc-shaped plate one 34, and a limiting block 38 is fixedly arranged at the top of the movable rod 36. The elastic member 37 is located between the arc-shaped plate two 35 and the arc-shaped plate one 34.

[0041] By the arc-shaped plate one 34 fitting on both ends of the formed PE film 9 and fitting with the edge of the formed PE film 9, the radian of the arc-shaped plate one 34 fits with the edge of the formed PE film 9. During the winding process, the arc-shaped plate one 34 continuously applies an appropriate pressure to the edge of the PE film, realizing the precise flattening of the formed PE film 9 with special edge hollowing and other forms. This flattening effect effectively eliminates defects such as edge warping and curling, makes the edge of the PE film smoother and flatter, not only improves the appearance quality of the formed PE film 9 with hollowing, but also enables the PE film to be wound tightly and orderly on the winding roller, reduces the need for re-arrangement due to uneven winding, and improves the overall quality of the PE film.

[0042] Through all the above embodiments, the working principle of the present invention is:

[0043] First, put the PE particles into the feeding hopper 2. The PE particles enter the extrusion device 3 through the feeding hopper 2 and are melted and plasticized under the action of barrel heating and screw shearing. The melt forms a molten film by flat extrusion through the extrusion die head 4. The molten film flows onto the casting extrusion roller 5 and the cooling roller 6. The excess edges are cut by the cutting knife and recycled through the recycling roller 8 into the feeding hopper 2 for crushing and reuse. Finally, the formed PE film 9 with hollowed edges is wound up by the winding roller 7.

[0044] Secondly, after starting the external drive of the drive shaft 15, the fixed disk 16 above it is continuously driven to rotate synchronously by the continuous rotation of the drive shaft 15. While the fixed disk 16 is rotating, the eccentric shaft 17 eccentrically arranged on the fixed disk 16 will slide on the fixed shaft 19 through the sleeve three 18. At this time, the swing blocks 20 at both ends of the fixed shaft 19 will continuously swing back and forth on the connecting rod 11, thereby driving the swing plate 21 to swing back and forth synchronously. The swing plate 21 is the component that directly contacts the PE film and applies a force. To ensure that when contacting the formed PE film 9 with a hollow design, a uniform and appropriate swinging force can be provided, which can effectively discharge the bubbles caused by the hollowing and will not damage the film surface. This kind of tiny deformation and vibration can effectively break the relatively stable PE melt structure around the bubbles. The bubbles originally wrapped by the PE melt, under the action of the swinging force, the interfacial tension between it and the melt will be disturbed. When this disturbance reaches a certain degree, the bubbles will start to rise and finally break on the surface or inside of the PE film, releasing the internal gas and discharging it through the hollow part of the PE forming die, which helps to reduce the holes and defects in the PE film and make the PE film smoother and more uniform.

[0045] Finally, before winding, the rotating shaft 29 on the fixed base plate 23 drives the movable plate 27 to be attached to both sides of the formed PE film 9 for limiting. The rotating shaft 29 rotates to drive the first connecting rod 30 fixedly arranged on its outer surface to rotate synchronously, and then drives the second connecting rod 32 to pull the fixed block 26 through the first connecting pin 31, so that the slider 25 on the fixed block 26 moves synchronously towards each other along the guide rail 24. The movable plate 27 fixed on the slider 25 moves synchronously towards the middle and is attached to both sides of the formed PE film 9 to limit the formed PE film 9, preventing the PE forming die from deviating during the winding process, ensuring that the hollow formed PE film 9 can be wound neatly and tightly on the winding roller, and improving the winding accuracy and efficiency. The first arc-shaped plate 34 is attached to both ends of the formed PE film 9 and fits with the edge of the formed PE film 9. The arc of the first arc-shaped plate 34 fits with the edge of the formed PE film 9. During the winding process, the first arc-shaped plate 34 continuously applies an appropriate pressure to the edge of the PE film, realizing the precise flattening of the formed PE film 9 with special shapes such as edge hollowing. This flattening effect effectively eliminates defects such as edge warping and curling, making the edge of the PE film smoother and flatter, not only improving the appearance quality of the hollow formed PE film 9, but also enabling the PE film to be wound tightly and orderly on the winding roller shaft 7.

[0046] Those of ordinary skill in the art should understand that the discussion of any embodiment above is only exemplary. Under the idea of the present invention, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other variations in different aspects of the present invention as described above. For the sake of brevity, they are not provided in detail.
