Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1

[0032] By Figure 1 , Figure 4 and Figure 5Provided, the film laminating machine for producing aluminum doors and windows of the present invention includes an operating table 1. Above the operating table 1, there are two movable frames 4. The operating table 1 is equipped with a translation mechanism for driving the two movable frames 4 to move horizontally. The operating table 1 is equipped with a position adjustment component for driving the rotation of the aluminum doors and windows. On the movable frame 4, there is a winding roller 6 for winding waste materials. Above the winding roller 6, there is a winding roller 5. The movable frame 4 is equipped with a damping rotation drive structure for respectively driving the rotation of the winding roller 5 and the winding roller 6. Between the winding roller 5 and the winding roller 6, there is a support roller 8. Both ends of the support roller 8 are fixedly connected to the movable frame 4. The movable frame 4 is fixedly installed with two fifth hydraulic expansion rods 57. The telescopic ends of the fifth hydraulic expansion rods 57 are fixedly installed with a first cutting knife 13 for cutting the protective film 7. The movable frame 4 is equipped with a film pressing and cutting structure for pasting the protective film 7 on the aluminum doors and windows.

[0033] The protective film 7 passes through the support roller 8 and the film pressing and cutting structure, and the end of the protective film 7 is fixed on the winding roller 6. The first cutting knife 13 is driven to move by the fifth hydraulic expansion rod 57. The first cutting knife 13 penetrates the protective film 7, and the winding roller 6 and the winding roller 5 are driven to rotate by the damping rotation drive structure. The winding roller 6 pulls the protective film 7 to move, and the first cutting knife 13 trims the edge of the protective film 7. When the trimmed length of the protective film 7 reaches the preset length, the aluminum doors and windows to be laminated are placed on the position adjustment component by a manipulator. One of the movable frames 4 is driven to move towards the aluminum doors and windows by the translation mechanism, so that the trimmed protective film 7 contacts the side surface of the aluminum doors and windows. The trimmed protective film 7 is pressed on the top and bottom of the aluminum doors and windows by the film pressing and cutting structure, and at the same time, the film pressing and cutting structure cuts off the pasted protective film 7;

[0034] After one side of the aluminum doors and windows is laminated, the movable frame 4 is driven to move in the reverse direction by the translation mechanism, so that the movable frame 4 returns to the initial position. At the same time, the damping rotation drive structure drives the winding roller 6 to rotate, so that the cut waste materials are wound on the winding roller 6. The aluminum doors and windows are driven to rotate by 90 degrees by the position adjustment component, so that the other side of the aluminum doors and windows faces another protective film 7. Similarly, another protective film 7 laminates the side of the aluminum doors and windows. The two protective films 7 can respectively laminate the two sides of the aluminum doors and windows in sequence, without the need for manual covering of the protective film 7 on the aluminum doors and windows, without relying on manpower, and improving the automation level.

Between the two side pressing rollers 11, two pressing rollers 10 are provided, and the pressing rollers 10 are fixedly connected to the mounting frame 9. On the side where the two side pressing rollers 11 are away from each other, two fixed rollers 12 are provided, and the fixed rollers 12 are fixedly connected to the mounting frame 9. On the side of the pressing roller 10 away from the mounting frame 9, a second cutting knife 15 is provided, and a cutting groove 14 adapted to the second cutting knife 15 is formed on the pressing roller 10.

[0037] The movable frame 4 is equipped with an elastic unit adapted to the second cutting knife 15. The elastic unit includes a tool holder 16 fixedly installed on the second cutting knife 15. Two first guiding columns 17 penetrate through the tool holder 16. The ends of the first guiding columns 17 and the movable frame 4 are fixedly connected through a first fixing plate 18. A tension spring 19 is sleeved outside the first guiding columns 17, and the two ends of the tension spring 19 are respectively fixedly connected to the tool holder 16 and the first fixing plate 18.

[0038] The pushing member includes two fixed frames 20 fixedly installed on the movable frame 4. The fixed frames 20 are fixedly installed with a first hydraulic telescopic rod 21, and the telescopic end of the first hydraulic telescopic rod 21 is fixedly connected to the mounting frame 9.

[0039] The damping rotation driving structure includes a first servo motor 23 fixedly installed on the movable frame 4. The output end of the first servo motor 23 is fixedly connected with a first damping disc 22. Second damping discs 24 are symmetrically arranged at both ends of the winding roller 5. The second damping discs 24 are fixedly connected to the movable frame 4. Third damping discs 25 are respectively in contact with the first damping disc 22 and the second damping discs 24. Rotating shafts 27 are provided at both ends of the winding roller 5 and the winding roller 6. A third support frame 56 is rotatably sleeved outside the rotating shafts 27. The third support frame 56 is fixedly connected to the movable frame 4. First mounting discs 26 are fixedly connected to both ends of the winding roller 5 and the winding roller 6. The first mounting discs 26 and the rotating shafts 27 are connected through a disassembly and assembly member, and the three third damping discs 25 are respectively fixedly connected to the corresponding three rotating shafts 27.

[0040] The disassembly and assembly member includes a second mounting disc 28 fixedly installed on the rotating shaft 27. A number of bolts 29 penetrate through the first mounting disc 26, and the bolts 29 penetrate through the corresponding second mounting disc 28. A nut 30 is sleeved at the end of the bolt 29 away from the first mounting disc 26. The translation mechanism includes second hydraulic telescopic rods 32 symmetrically arranged on both sides of the movable frame 4. The second hydraulic telescopic rods 32 and the operating table 1 are fixedly connected through a second fixing plate 31. The telescopic ends of the second hydraulic telescopic rods 32 and the movable frame 4 are fixedly connected through a connecting plate 33. A number of rollers 34 are fixedly connected to the bottom end of the movable frame 4, and the rollers 34 are in contact with the top of the operating table 1.

[0041] The protective film 7 passes through from one side of the pressing roller 10 towards the aluminum door and window. The first servo motor 23 drives the first damping disc 22 to rotate. The first damping disc 22 drives the third damping disc 25, the rotating shaft 27, the second mounting disc 28, and the first mounting disc 26 to rotate synchronously through friction, so that the winding roller 6 pulls the protective film 7 to move. The winding roller 5 drives the third damping disc 25 to rotate relative to the second damping disc 24 and the movable frame 4 through the first mounting disc 26, the second mounting disc 28, and the rotating shaft 27. At the same time, the fifth hydraulic telescopic rod 57 drives the first cutting knife 13 to move to the cutting position. The first cutting knife 13 penetrates the protective film 7. As the protective film 7 continues to move, the first cutting knife 13 cuts the protective film 7;

[0042] When the cutting length of the protective film 7 reaches the preset value, the first servo motor 23 stops driving the first damping disc 22 to rotate, and the fifth hydraulic telescopic rod 57 drives the first cutting knife 13 to move in the reverse direction, so that the first cutting knife 13 is no longer in the cutting station. The second hydraulic telescopic rod 32 drives the connecting plate 33 and the movable frame 4 to move, so that the movable frame 4 moves towards the aluminum door and window, and the roller 34 rolls on the operating table 1. Through the design of the roller 34, the movable frame 4 moves smoothly relative to the operating table 1;

[0043] When the protective film 7 contacts the side of the aluminum door and window, the first hydraulic telescopic rod 21 drives the mounting frame 9 to move, so that two adjacent pressing rollers 10 move to the upper and lower sides of the aluminum door and window respectively. The pressing rollers 10 attach the trimmed protective film 7 to the aluminum door and window. The two adjacent side pressing rollers 11 attach the excess parts on both sides of the protective film 7 to the other two sides of the aluminum door and window. At the same time, the fixing roller 12 presses the trimmed waste material to prevent the waste material from shaking onto the aluminum door and window;

[0044] After the pressing roller 10 moves to the preset position, the second cutting knife 15 is inserted into the cutting groove 14 on the pressing roller 10, and the second cutting knife 15 cuts the protective film 7. Meanwhile, the first hydraulic telescopic rod 21 pushes the mounting bracket 9 to continue moving, and the pressing roller 10 continues to move horizontally, ensuring that the cut-off protective film 7 adheres to the aluminum door and window. At the same time, the pressing roller 10 pushes the second cutting knife 15 and the tool holder 16 to move synchronously in the horizontal direction. The tool holder 16 slides relative to the first guide post 17, and the tension spring 19 is in a stretched state. During the process of the pressing roller 10 and the fixed roller 12 pushing the protective film 7, the protective film 7 pulls the winding roller 5 and the winding roller 6 to rotate. The winding roller 5 and the winding roller 6 respectively drive the rotating shaft 27 to rotate through the first mounting disc 26 and the second mounting disc 28, and the rotating shaft 27 drives the third damping disc 25 to rotate relative to the first damping disc 22 or the second damping disc 24. After the protective film 7 is pasted, the aluminum door and window is driven to move in the reverse direction by the movable frame 4. The pressing roller 10 no longer presses the second cutting knife 15 and the tool holder 16, and the tension spring 19 drives the tool holder 16 and the second cutting knife 15 to reset to the initial position in the reverse direction. And the first damping disc 22 is driven to rotate by the first servo motor 23, so that the waste material is wound on the winding roller 6, and the waste material pulls the winding roller 5 to rotate. When the next section of the protective film 7 to be cut moves to one side of the support roller 8, the fifth hydraulic telescopic rod 57 drives the first cutting knife 13 to move to the cutting position. At the same time, the winding roller 6 continues to rotate, and the edge of the next section of the protective film 7 to be attached can be cut again. When the winding roller 6 and the winding roller 5 need to be replaced, the staff drives the nut 30 to rotate, so that the nut 30 is disengaged from the bolt 29. The staff drives the bolt 29 to disengage from the first mounting disc 26 and the second mounting disc 28, and the limitation of the position of the first mounting disc 26 can be released. The staff drives the winding roller 6 and the winding roller 5 to move, so that the first mounting disc 26 is no longer located between the two second mounting discs 28, and the removal of the winding roller 6 and the winding roller 5 can be completed.

When the film coating on one side of the aluminum doors and windows is completed, the movable frame 4 is driven to move in the reverse direction by the translation mechanism, so that the movable frame 4 returns to the initial position. At the same time, the damping rotation drive structure drives the winding roller 6 to rotate, so that the cut waste is wound on the winding roller 6. The aluminum doors and windows are driven to rotate 90 degrees by the position adjustment component, so that the other side edge of the aluminum doors and windows faces another protective film 7. Similarly, another protective film 7 films the side edge of the aluminum doors and windows. The two protective films 7 can film the two side edges of the aluminum doors and windows in sequence respectively, without the need for manual covering of the protective film 7 on the aluminum doors and windows, without relying on manpower, and improving the automation level;

[0050] The protective film 7 passes through from the side of the pressing roller 10 towards the aluminum door and window. The first servo motor 23 drives the first damping disc 22 to rotate. The first damping disc 22 drives the third damping disc 25, the rotating shaft 27, the second mounting disc 28, and the first mounting disc 26 to rotate synchronously through friction, so that the winding roller 6 pulls the protective film 7 to move. The winding roller 5 drives the third damping disc 25 to rotate relative to the second damping disc 24 and the movable frame 4 through the first mounting disc 26, the second mounting disc 28, and the rotating shaft 27. At the same time, the fifth hydraulic telescopic rod 57 drives the first cutting knife 13 to move to the cutting position. The first cutting knife 13 penetrates the protective film 7. As the protective film 7 continues to move, the first cutting knife 13 cuts the protective film 7. When the cutting length of the protective film 7 reaches the preset value, the first servo motor 23 stops driving the first damping disc 22 to rotate, and the fifth hydraulic telescopic rod 57 drives the first cutting knife 13 to move in the reverse direction, so that the first cutting knife 13 is no longer located at the cutting station. The second hydraulic telescopic rod 32 drives the connecting plate 33 and the movable frame 4 to move, so that the movable frame 4 moves towards the aluminum door and window, and the roller 34 rolls on the operating table 1. Through the design of the roller 34, the movable frame 4 moves smoothly relative to the operating table 1. When the protective film 7 contacts the side of the aluminum door and window, the first hydraulic telescopic rod 21 drives the mounting frame 9 to move, so that the adjacent two pressing rollers 10 move to the upper and lower sides of the aluminum door and window respectively. The pressing rollers 10 attach the trimmed protective film 7 to the aluminum door and window. The excess parts on both sides of the protective film 7 are attached to the other two sides of the aluminum door and window by the adjacent two side pressing rollers 11. At the same time, the fixed roller 12 presses the trimmed waste material to prevent the waste material from shaking onto the aluminum door and window. When the pressing roller 10 moves to the preset position, the second cutting knife 15 is inserted into the cutting groove 14 on the pressing roller 10. The second cutting knife 15 cuts the protective film 7, and the first hydraulic telescopic rod 21 pushes the mounting frame 9 to continue moving. The pressing roller 10 moves continuously in the horizontal direction to ensure that the cut-off protective film 7 is attached to the aluminum door and window. At the same time, the pressing roller 10 pushes the second cutting knife 15 and the tool holder 16 to move synchronously in the horizontal direction. The tool holder 16 slides relative to the first guide post 17. The tension spring 19 is in a stretched state. During the process of the pressing roller 10 and the fixed roller 12 pushing the protective film 7, the protective film 7 drives the winding roller 5 and the winding roller 6 to rotate. The winding roller 5 and the winding roller 6 drive the rotating shaft 27 to rotate through the first mounting disc 26 and the second mounting disc 28 respectively. The rotating shaft 27 drives the third damping disc 25 to rotate relative to the first damping disc 22 or the second damping disc 24. When the protective film 7 finishes pasting, the movable frame 4 drives the aluminum door and window to move in the reverse direction. The pressing roller 10 no longer presses the second cutting knife 15 and the tool holder 16. The tension spring 19 drives the tool holder 16 and the second cutting knife 15 to reset to the initial position in the reverse direction. And the first servo motor 23 drives the first damping disc 22 to rotate, so that the waste material is wound around the winding roller 6, and the waste material drives the winding roller 5 to rotate. When the next section of the protective film 7 to be cut moves to one side of the support roller 8, the fifth hydraulic telescopic rod 57 drives the first cutting knife 13 to move to the cutting position.Meanwhile, the winding roller 6 rotates continuously, so that the edge of the protective film 7 to be attached in the next section can be trimmed again. When the winding roller 6 and the winding roller 5 need to be replaced, the staff drives the nut 30 to rotate, so that the nut 30 disengages from the bolt 29. The staff drives the bolt 29 to disengage from the first mounting plate 26 and the second mounting plate 28, and the limitation of the position of the first mounting plate 26 can be released. The staff drives the winding roller 6 and the winding roller 5 to move, so that the first mounting plate 26 is no longer located between the two second mounting plates 28, and the removal of the winding roller 6 and the winding roller 5 can be completed.

[0051] The fourth hydraulic telescopic rod 38 is driven to move the second support frame 39 upward, so that the horizontal position of the top of the two second support frames 39 is higher than the horizontal position of the top of the first support frame 37. The aluminum door and window is placed on the top of the two second support frames 39 by an external manipulator. The first bevel gear 45 is driven to rotate by the second servo motor 44. The first bevel gear 45 drives the four second bevel gears 50 to rotate. The second bevel gears 50 drive the threaded sleeves 47 to rotate. Two of the threaded sleeves 47 drive the first pressing plate 42 to move towards the inner wall of the aluminum door and window through the corresponding two lead screws 46, so that the first pressing plate 42 presses the inner wall of the aluminum door and window. The other two threaded sleeves 47 drive the second pressing plate 43 to move towards the control box 40 through the corresponding two lead screws 46. The protective film 7 can apply the film to the side of the aluminum door and window located above the first support frame 37. When the film application of one side of the aluminum door and window is completed, the third hydraulic telescopic rod 36 is driven to move the first support frame 37 upward, so that the first support frame 37 supports the bottom of the aluminum door and window. The fourth hydraulic telescopic rod 38 is driven to move the second support frame 39 downward, so that the second support frame 39 no longer supports the aluminum door and window. The first bevel gear 45 is driven to rotate in the reverse direction by the second servo motor 44, so that the two second pressing plates 43 press the inner wall of the aluminum door and window, and the two first pressing plates 42 no longer press the inner wall of the aluminum door and window. The position of the aluminum door and window is limited by the two second pressing plates 43 to prevent the aluminum door and window from shaking relative to the rotating frame 35. The second gear 55 is driven to rotate by the third servo motor 54. The second gear 55 drives the support shaft 52 and the rotating frame 35 to rotate through the first gear 53, and the aluminum door and window located above the rotating frame 35 can be rotated.
