[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-10 The present invention provides two technical solutions, specifically including the following embodiments:

[0031] Example 1:

[0032] A forming device for POE encapsulation film of solar cells includes a body 1. A protective cover 101 is rotatably mounted on one side of the top surface of the body 1. An extruder 2 is fixedly mounted on the other side of the top surface of the body 1, and a feed cylinder 201 is fixedly mounted on the top surface of the extruder 2.

A cutting assembly is provided inside the body 1, including an arc frame 9. A limit frame 902 is fixedly mounted inside the body 1. A connecting rod 903 is fixedly mounted at the end of the arc frame 9 and slides inside the arc frame 9 via the connecting rod 903. A return spring 9021 is fixedly mounted between the arc frame 9 and the connecting rod 903. An edge material receiving roller assembly is provided inside the arc frame 9. A limit assembly is provided on the inner wall of the arc frame 9. A rectangular plate frame 12 is fixedly mounted inside the body 1. Inside the rectangular frame 12, an arc-shaped support plate 1201 and an outer slide 13 are fixedly installed. Inside the outer slide 13, a cutting blade 14 is slidably installed. A reset component is provided between the middle of the side of the cutting blade 14 and the rectangular frame 12. A transmission component is provided between the bottom of the cutting blade 14 and the arc frame 9. The transmission component includes a push plate 15. The push plate 15 is fixedly installed at the bottom of the cutting blade 14 and is slidably connected to the outer slide 13 through the cooperation of the cutting blade 14. A positioning post 1301 is installed on the outside of the outer slide 13 and is fixedly connected to the rectangular frame 12 through the positioning post 1301. Inside the push plate 15, an inner slide plate 1501 is slidably installed. Spring bodies 1502 are fixedly installed between the two ends of the side of the inner slide plate 1501 and the inside of the push plate 15. A baffle 905 is fixedly installed in the middle of the top surface of the arc frame 9. The end of the baffle 905 is in contact with the inner slide plate 1501.

[0033] In this embodiment of the invention, the reset assembly includes a transmission column 16, which is slidably installed inside the rectangular plate frame 12 and its end is fixedly connected to the middle of the side of the cutting blade plate 14. A magnet 1601 is fixedly installed at the end of the transmission column 16, and the installation position of the magnet 1601 corresponds to the adsorption ring 1602 fixedly installed on the side of the rectangular plate frame 12. An elastic reset device, which is a spring, is fixedly installed between the transmission column 16 and the rectangular plate frame 12 for resetting the transmission column 16. An adjustment assembly is provided at the bottom of the rectangular plate frame 12 for the installation of the cutting blade plate 14. The position is flush with the arc-shaped support plate 1201. A pressure plate 1401 is fixedly installed at the end of the cutting blade plate 14. The pressure plate 1401 is made of rubber and its installation length exceeds the length of the cutting blade plate 14. The adjustment assembly includes an adjustment screw 17, which is rotatably installed on the bottom side of the rectangular plate frame 12 via a threaded connection. The end of the adjustment screw 17 is flush with the inner slide plate 1501. The edge material collecting roller assembly includes a transmission roller 901, which is rotatably installed inside the machine body 1. Several grooves 901 are symmetrically opened on the outer side of the transmission roller 901. 1. A winding roller 9012 is slidably mounted on a slide groove 9011. The winding roller 9012 is rotatably mounted inside the arc frame 9 through the cooperation of a transmission roller 901. The cutting assembly also includes a trimming frame 10, which is fixedly mounted inside the machine body 1. Trimming slides 11 are slidably mounted on both sides of the trimming frame 10. Positioning bolts 1101 are provided on the top surface of both trimming slides 11, and trimming blades 1102 are fixedly mounted on the bottom of both trimming slides 11. The material conveying assembly includes a first conveying roller 4 and a second conveying roller 5. All components are rotatably installed inside the machine body 1. A take-up roller 3 is rotatably installed at the inner end of the machine body 1. The limiting component includes limiting rubber sheets 904. There are several limiting rubber sheets 904, which are fixedly installed on both sides of the inside of the arc frame 9. The limiting rubber sheets 904 on both sides are symmetrical to each other. The driving component includes a drive motor, a transmission track, and a transmission gear, which are used to realize the operation of the material conveying component. In the material conveying component, the second conveying roller 5, the transmission roller 901, and the edge material support rod 102 all rotate counterclockwise, while the first conveying roller 4 rotates clockwise. All of them are driven by the driving component.

[0034] In use, the material is first poured into the extruder 2 through the feed cylinder 201. Then, the extruder 2 runs and the formed film is extruded from its end. The film is then manually wound around the second conveyor roller 5 and the first conveyor roller 4 in sequence, and then its end is wound to the outside of the take-up roller 3. The formed film is wound by the operation of the drive assembly. During the winding, the distance of the film cutting edge is adjusted by the cooperation of the cutting edge slide 11. After the adjustment is completed, it is fixed by the positioning bolt 1101. When the wound film is cut by the cutting edge knife 1102, the two sides are pulled down by hand to make it pass around the edge material support rod 102 and then wind to the take-up roller 9012. Then, the drive roller 901 drives the take-up roller 9012 to take in the material.

[0035] Furthermore, through the arrangement of the cutting components, as the diameter of the edge material increases with the take-up of the winding roller 9012, it can contact the outer arc frame 9. Then, through continuous winding, the arc frame 9 is pushed outward, causing it to slide inside the limiting frame 902 via the connecting rod 903 at the end. As the arc frame 9 moves outward, the inner slide plate 1501 is pushed outward via the baffle 905, causing the push plate 15 and the cutting blade 14 to slide inside the outer slide frame 13. At the same time, the transmission column 16 can slide outward by pushing until the inner slide plate 1501 contacts the adjusting screw 17 and is then retracted into the push plate 15. As the inner slide plate 1501 disengages from the baffle 905, the cutting blade 14 can be reset through the cooperation of the transmission column 16 and the magnet 1601 with the adsorption ring 1602, as well as the elastic reset between the transmission column 16 and the rectangular plate frame 12. The device works in conjunction with the cutting blade 14 to return to its original position and contact the arc-shaped support plate 1201, cutting the wound edge material. The pressure plate 1401, which is fixedly installed at the front end of the cutter, first comes into contact with the edge material and then is clamped by the arc-shaped support plate 1201, facilitating subsequent winding operations. At the same time, by rotating the adjusting screw 17, the winding thickness of the edge material can be adjusted, facilitating cutting and replacement of the edge material at different winding thicknesses. With the cooperation of the arc-shaped frame 9, the edge material can continuously stay in contact with the inner wall of the arc-shaped frame 9 during the winding process, ensuring the winding effect of the edge material. At the same time, the rubber limiting plates 904 fixedly installed on both sides inside the arc-shaped frame 9 can make the side of the adhesive film fit with the rubber limiting plates 904 during the winding process, avoiding skewing or scattering during the winding process, thus improving the winding effect of the equipment.

[0036] This invention also discloses a multi-pass embossing assembly for solar cell POE encapsulation film, including a bottom support roller 6 and an embossing roller 7. A rotating shaft 701 is slidably sleeved inside both the bottom support roller 6 and the embossing roller 7. The bottom support roller 6 is rotatably mounted inside a machine body 1 via its internal rotating shaft 701. A positioning frame 8 is fixedly mounted inside the machine body 1. A bearing is sleeved at the end of the rotating shaft 701 inside the embossing roller 7, and the bearing is slidably mounted inside the positioning frame 8. A hydraulic cylinder 801 is fixedly mounted inside the machine body 1, and the end of the hydraulic cylinder 801 is fixedly connected to the bearing. The installation positions of the bottom support roller 6 and the embossing roller 7 are located on one side of the cutting assembly and correspond to each other. The bottom support roller 6 and the embossing roller 7 always remain parallel.

[0037] When in use, as the conveyed film is conveyed forward by the bottom support roller 6 for winding, the operation of the hydraulic cylinder 801, through the cooperation of the bearing and the rotating shaft 701, drives the embossing roller 7 to move downward until it contacts the conveyed film, thereby driving the embossing roller 7 to rotate and perform embossing on the outer side of the film, thus improving the convenience of embossing and winding of the equipment.

[0040] In this embodiment of the invention, the reset assembly includes a transmission column 16, which is slidably installed inside the rectangular plate frame 12 and its end is fixedly connected to the middle of the side of the cutting blade plate 14. A magnet 1601 is fixedly installed at the end of the transmission column 16, and the installation position of the magnet 1601 corresponds to the adsorption ring 1602 fixedly installed on the side of the rectangular plate frame 12. An elastic reset device, which is a spring, is fixedly installed between the transmission column 16 and the rectangular plate frame 12 for resetting the transmission column 16. The bottom of the rectangular plate frame 12... An adjustment assembly is provided. The installation position of the cutting blade 14 is flush with the arc-shaped support plate 1201. A pressure plate 1401 is fixedly installed at the end of the cutting blade 14. The pressure plate 1401 is made of rubber and its installation length exceeds the length of the cutting blade 14. The adjustment assembly includes an adjustment screw 17, which is rotatably installed on the bottom side of the rectangular plate frame 12 via a threaded connection. The end of the adjustment screw 17 is flush with the inner slide plate 1501. The edge material receiving roller assembly includes a drive roller 901, which rotates... The cutting assembly is installed inside the machine body 1. A plurality of grooves 9011 are symmetrically provided on the outer side of the transmission roller 901, and a winding roller 9012 is slidably mounted through the grooves 9011. The winding roller 9012 is rotatably mounted inside the arc-shaped frame 9 through the cooperation of the transmission roller 901. The cutting assembly also includes a trimming frame 10, which is fixedly installed inside the machine body 1. Trimming slides 11 are slidably mounted on both sides of the trimming frame 10. Positioning bolts 1101 are provided on the top surface of both trimming slides 11 on both sides. Each part is fixedly equipped with a cutting blade 1102. The material conveying assembly includes a first conveying roller 4 and a second conveying roller 5. The first conveying roller 4 and the second conveying roller 5 are rotatably installed inside the machine body 1. A winding roller 3 is rotatably installed at the inner end of the machine body 1. The drive assembly includes a drive motor, a transmission track, and a transmission gear, which are used to realize the operation of the material conveying assembly. In the material conveying assembly, the second conveying roller 5, the transmission roller 901, and the edge material support rod 102 all rotate counterclockwise, while the first conveying roller 4 rotates clockwise. All of them are driven by the drive assembly.

[0041] In use, the material is first poured into the extruder 2 through the feed cylinder 201. Then, the extruder 2 runs and the formed film is extruded from its end. The film is then manually wound around the second conveyor roller 5 and the first conveyor roller 4 in sequence, and then its end is wound to the outside of the take-up roller 3. The formed film is wound by the operation of the drive assembly. During the winding, the distance of the film cutting edge is adjusted by the cooperation of the cutting edge slide 11. After the adjustment is completed, it is fixed by the positioning bolt 1101. When the wound film is cut by the cutting edge knife 1102, the two sides are pulled down by hand to make it pass around the edge material support rod 102 and then wind to the take-up roller 9012. Then, the drive roller 901 drives the take-up roller 9012 to take in the material.

[0042] Furthermore, through the arrangement of the cutting assembly, as the diameter of the edge material increases with the take-up of the winding roller 9012, it can contact the outer arc frame 9. Then, through continuous winding, the arc frame 9 is pushed outward, causing it to slide inside the limiting frame 902 via the connecting rod 903 at the end. As the arc frame 9 moves outward, the inner slide plate 1501 can be pushed outward via the baffle 905, causing the push plate 15 and the cutting blade 14 to slide inside the outer slide frame 13. At the same time, the transmission column 16 can slide outward by pushing until the inner slide plate 1501 contacts the adjusting screw 17 and is then retracted into the push plate 15. As the inner slide plate 1501 disengages from the baffle 905, the cutting blade 14 can slide outward via the transmission column 1501. The cooperation between magnet 1601 and adsorption ring 1602, and the cooperation between transmission column 16 and rectangular plate frame 12, allows cutting blade 14 to reset and contact arc support plate 1201, cutting the wound edge material. The pressure plate 1401 fixedly installed at the front end of the cut can first fit with the edge material, and then be clamped by arc support plate 1201, which facilitates subsequent winding operations. At the same time, by rotating adjustment screw 17, the winding thickness of the edge material can be adjusted, which facilitates cutting and changing operations of the edge material at different winding thicknesses. With the cooperation of arc frame 9, the edge material can continuously keep in contact with the inner wall of arc frame 9 during the winding process, ensuring the winding effect of the edge material.

[0043] This invention also discloses a multi-pass embossing assembly for solar cell POE encapsulation film, including a bottom support roller 6 and an embossing roller 7. A rotating shaft 701 is slidably sleeved inside both the bottom support roller 6 and the embossing roller 7. The bottom support roller 6 is rotatably mounted inside a machine body 1 via its internal rotating shaft 701. A positioning frame 8 is fixedly mounted inside the machine body 1. A bearing is sleeved at the end of the rotating shaft 701 inside the embossing roller 7, and the bearing is slidably mounted inside the positioning frame 8. A hydraulic cylinder 801 is fixedly mounted inside the machine body 1, and the end of the hydraulic cylinder 801 is fixedly connected to the bearing. The installation positions of the bottom support roller 6 and the embossing roller 7 are located on one side of the cutting assembly and correspond to each other. The bottom support roller 6 and the embossing roller 7 always remain parallel.

[0044] When in use, as the conveyed film is conveyed forward by the bottom support roller 6 for winding, the operation of the hydraulic cylinder 801, through the cooperation of the bearing and the rotating shaft 701, drives the embossing roller 7 to move downward until it contacts the conveyed film, thereby driving the embossing roller 7 to rotate and perform embossing on the outer side of the film, thus improving the convenience of embossing and winding of the equipment.
