[0002] Doors and windows are important structures for indoor lighting, ventilation, and traffic evacuation, and they also have functions such as heat preservation, heat insulation, sound insulation, and fire prevention.

[0003] For related technologies, please refer to Chinese utility model patent with authorization announcement number CN216707427U, which discloses a door panel flipping assembly fixture, including a left composite panel, a splicing column and a composite filling layer. A right composite panel is fixed to one side of the left composite panel by splicing. A sealing partition is tightly attached to the outer wall of one side of both the left and right composite panels. The splicing column is set at the middle of one side of the left composite panel, and the other end of the splicing column is fixedly connected to a splicing column head by welding. A splicing groove is opened at the inner end of the right composite panel, and locking plates are set at both the upper and lower ends of the left side of the splicing groove.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the door panels need to be flipped during the plastering process. When flipping the door panels, the required lifting height varies depending on the width of the different door panels. Therefore, in the door panel plastering process, it is necessary to manually adjust the lifting height of the door panels according to the different door panel widths, resulting in a waste of human resources. Summary of the Invention

[0005] To address the issue of the required height for automatic door panel flipping, this application provides a device and method for preparing thermally insulated aluminum alloy doors and windows.

[0006] The manufacturing apparatus for thermally insulated aluminum alloy doors and windows provided in this application adopts the following technical solution:

[0007] A device for manufacturing thermally insulated aluminum alloy doors and windows includes a base, a support frame fixed to the top surface of the base, and a lifting rod slidably disposed within the support frame. A connecting rod is fixed to the bottom surface of the lifting rod. A sliding plate is slidably connected to the side wall of the support frame along its length. An electromagnet is fixed to the side of the sliding plate away from the lifting rod. A magnetic suction plate that can attract the electromagnet is fixed to the side wall of the support frame. A suction plate is slidably disposed to the bottom surface of the connecting rod along its length. A connecting piece is slidably connected to the suction plate along its vertical direction. Several fixed pieces are fixed to the bottom surface of the connecting rod, and the fixed pieces are electrically connected to the electromagnet. A movable piece is fixed to the top surface of the connecting piece, and the movable piece is electrically connected to a power source.

[0008] By adopting the above technical solution, after the suction plate 2 moves to the edge of the door panel, the connecting piece 3 on the suction plate 2 moves, and the fixed piece 2 and the moving piece 2 make electrical contact. After the electromagnet 3 is connected to the power supply, it generates an attraction effect on the magnetic suction piece, thereby placing the sliding plate horizontally on the moving path of the lifting rod, which blocks the upward movement of the lifting rod and causes the lifting rod to stop moving. Since each fixed piece 2 corresponds to an electromagnet 3, when the moving piece 2 contacts the fixed piece 2, the electromagnet 3 corresponding to the fixed piece 2 is activated and driven to move. By setting the electromagnet 3 at different heights, the purpose of stopping the lifting rod at different heights can be achieved, which facilitates the automatic identification of the door panel width and moves the door panel to the corresponding height according to the door panel width, making it convenient to flip the door panel at the appropriate height.

[0009] Optionally, the bottom surface of the connecting rod is provided with a sliding groove four, a motor two is fixed to the side wall of the sliding groove four, and a lead screw two is fixed to the output end of the motor two; the lead screw two is rotatably disposed in the sliding groove four; a sliding plate that is threadedly engaged with the lead screw two is fixed to the top surface of the suction plate two.

[0010] By adopting the above technical solution, the second lead screw drives the second suction plate to move through the sliding plate thread engagement. When the second suction plate stops moving, the movement of the second suction plate can be stopped by turning off the second motor.

[0011] Optionally, the suction plate two has a mounting groove one on its bottom surface and a mounting groove two on its top surface; a connecting piece one is vertically slidable on the suction plate two through the mounting groove one, and the suction plate two is connected to the connecting piece two along its own length direction through the mounting groove two; the connecting piece one and the connecting piece two have inclined surfaces two on their opposite inner sides; a mounting groove three is formed on the top surface of the mounting groove two, and the connecting piece three is vertically slidably connected to the suction plate two through the mounting groove three; a slot four is formed on the top surface of the connecting piece two that can be inserted into the connecting piece three; the side of the connecting piece three away from the connecting piece one and the side of the slot four away from the connecting piece one have inclined surfaces three that can abut against each other.

[0012] By adopting the above technical solution, when the suction plate 2 is in contact with the door panel, the connecting piece 1 retracts into the mounting groove 1. When the suction plate 2 moves to the edge of the door panel, the connecting piece 1 loses its pressing relationship with the door panel and moves downward, thereby separating the connecting piece 2 from the connecting piece 1. During the process of the connecting piece 2 moving towards the side of the connecting piece 1, it applies an upward pushing force to the connecting piece 3, thereby causing the connecting piece 3 to drive the moving piece 2 to make electrical contact with the fixed piece 2, and making the electromagnet 3 conduct.

[0014] By adopting the above technical solution, suction plate one attracts the door panel through electromagnet one; when suction plate two moves to the edge of the door panel, the movement of connecting piece one will cause fixed piece one and moving piece one to make electrical contact, thereby connecting electromagnet two to the power supply, and electromagnet two will simultaneously attract the door panel.

[0015] Optionally, a second spring is fixed to the side of the connecting piece two near the lifting rod, and the end of the second spring away from the connecting piece two is fixedly connected to the inner wall of the mounting groove two near the lifting rod.

[0016] By adopting the above technical solution, the second spring applies a spring force to the second connecting piece towards the side closer to the first connecting piece, thereby resetting the second connecting piece towards the side closer to the first connecting piece, while the second connecting piece can push the first connecting piece downward.

[0017] Optionally, the support frame includes two slide rails fixed to the top surface of the base and arranged opposite to each other; a motor is fixed to the bottom of the slide rails, and a lead screw is fixed to the output end of the motor; transmission boxes are fixed to both ends of the support frame; a rotating groove is provided inside the transmission box, and a threaded tube that is threadedly engaged with the lead screw is rotatably installed in the transmission box through the rotating groove; a sliding groove is provided on the peripheral side wall of the rotating groove, and a plug-in piece is connected to the transmission box radially along the rotating groove through the sliding groove; a slot is provided on the peripheral side of the threaded tube, which can be inserted into the plug-in piece; a spring is fixed to the side of the plug-in piece away from the threaded tube, and the end of the spring away from the threaded tube is fixedly connected to the side wall of the sliding groove away from the rotating groove.

[0018] By adopting the above technical solution, the threaded tube and the lead screw maintain a threaded engagement to provide power for the lifting rod to rise; when the threaded tube is in the limit state, the threaded tube and the lead screw maintain a threaded engagement, and the plug-in plate provides a limit function for the threaded tube; when the plug-in plate separates from the threaded tube, the lifting rod can stop rising.

[0019] Optionally, a pressure plate is vertically slidable above the transmission box, and the pressure plate is sleeved around the circumference of the lead screw; a second plug-in piece is fixed on the bottom surface of the pressure plate, and a second sliding groove is opened on the top surface of the transmission box for plugging into the second plug-in piece; a second slot is opened on the top surface of the second plug-in piece for plugging into the second plug-in piece, and a first inclined surface that can abut against each other is opened on the side of the second plug-in piece away from the threaded tube and the side wall of the second slot away from the threaded tube, respectively.

[0020] By adopting the above technical solution, the second insertion piece at the bottom of the pressure plate abuts against the second slot on the first insertion piece, which can push the first insertion piece to move, thereby separating the first insertion piece from the threaded tube, releasing the threaded tube from its restricted state, and stopping the lifting rod from rising.

[0021] Optionally, a rack is fixed to the bottom surface of the pressure plate, and a sliding groove three is provided on the top surface of the transmission box, which can be inserted into the rack; a gear that meshes with the rack is rotatably installed on the side wall of the sliding groove three away from the threaded tube, and the gear is fixedly connected to the lifting rod on the side away from the threaded tube.

[0022] By adopting the above technical solution, during the pressing process of the pressure plate, the rack and gear meshing can drive the lifting rod to rotate, thereby completing the flipping action of the door panel.

[0023] Optionally, a spring is fixed to the side of the electromagnet three near the slide rail, and the side of the spring three away from the electromagnet three is fixedly connected to the side wall of the slide rail away from the lifting rod.

[0024] By adopting the above technical solution, spring three provides elastic force to the slide plate to the side away from the slide rail, so that after electromagnet three is disconnected from the power supply, spring three can drive the slide plate to reset to the side away from the slide rail, thereby removing the obstruction effect of the slide plate on the lifting rod when it rises.

[0025] The method for manufacturing thermally insulated aluminum alloy doors and windows provided in this application adopts the following technical solution:

[0026] A method for preparing thermally insulated aluminum alloy doors and windows includes the following steps:

[0027] The door panel to be coated is transported to the support frame, and the surface of the door panel is coated; the lifting rod is lowered to attract the door panel; after flipping the door panel, the other surface of the door panel is coated.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. After suction plate two moves to the edge of the door panel, connecting piece three on suction plate two moves, making fixed piece two and moving piece two electrically contact each other. After electromagnet three is connected to the power supply, it attracts the magnetic suction piece, thus placing the sliding plate horizontally on the moving path of the lifting rod, blocking the upward movement of the lifting rod and causing it to stop moving. Since each fixed piece two corresponds to an electromagnet three, when moving piece two contacts fixed piece two, the electromagnet three corresponding to fixed piece two is activated and driven to move. By setting electromagnet three at different heights, the lifting rod can be stopped at different heights, which facilitates automatic identification of the door panel width and moves the door panel to the corresponding height according to the door panel width, making it convenient to flip the door panel at the appropriate height.

[0030] 2. When suction plate 2 is in contact with the door panel, connecting piece 1 retracts into mounting groove 1. When suction plate 2 moves to the edge of the door panel, connecting piece 1 loses its pressing relationship with the door panel and moves downward, thereby separating connecting piece 2 from connecting piece 1. During the process of connecting piece 2 moving towards connecting piece 1, it applies an upward pushing force to connecting piece 3, thereby causing connecting piece 3 to drive moving piece 2 to make electrical contact with fixed piece 2, and making electromagnet 3 conduct.

[0031] 3. The threaded tube and the lead screw maintain a threaded engagement to provide power for the lifting rod to rise; when the threaded tube is in the limit state, the threaded tube and the lead screw maintain a threaded engagement, and the plug plate provides a limit function for the threaded tube; when the plug plate separates from the threaded tube, the lifting rod can stop rising.

[0037] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0038] This application discloses an apparatus and method for preparing thermally insulated aluminum alloy doors and windows. (Refer to...) Figure 1 and Figure 2 A manufacturing apparatus for thermally insulated aluminum alloy doors and windows includes a base 1, a support frame 2 fixed to the top surface of the base 1, and a lifting rod 3 vertically slidable within the support frame 2. The support frame 2 includes two slide rails 21 fixed to the top surface of the base 1 and arranged opposite to each other, and a crossbar 22 rotatably mounted on the top of the two slide rails 21. A motor 23 is fixed to the bottom of each slide rail 21, and a lead screw 24 is fixed to the output end of the motor 23. Transmission boxes 25, which can be threadedly engaged with the lead screw 24, are fixed to both ends of the support frame 2.

[0039] During the door panel painting process, one side of the door panel needs to be painted first, and then the door panel is flipped over to paint the other side. Because the width of the door panels is inconsistent, during the flipping process, the door panel needs to be raised to a suitable height according to its width before flipping it over.

[0040] Reference Figure 2 and Figure 3The transmission box 25 has a rotating groove 26, through which a threaded tube 27, which is threaded to engage with the lead screw 24, is rotatably mounted. A sliding groove 28 is formed on the circumferential side wall of the rotating groove 26, through which a connector 29 is radially connected to the transmission box 25. A slot 11 is formed on the circumferential side of the threaded tube 27, which can be inserted into the connector 29. A spring is fixed to the side of the connector 29 away from the threaded tube 27, and the end of the spring away from the threaded tube 27 is fixedly connected to the side wall of the sliding groove 28 away from the rotating groove 26.

[0041] When the threaded tube 27 is in the limited position, the lead screw 24 drives the transmission box 25 to move vertically through the threaded engagement of the threaded tube 27. The plug-in plate 29 provides a limiting function for the threaded tube 27. When the plug-in plate 29 separates from the threaded tube 27, the threaded tube 27 loses its limiting function, and the threaded tube 27 rotates with the lead screw 24, while the lifting rod 3 stops rising.

[0042] Reference Figure 2 and Figure 3 A pressure plate 4 is vertically slidable above the transmission box 25, and the pressure plate 4 is sleeved around the lead screw 24. A second insertion piece 41 is fixed to the bottom surface of the pressure plate 4, and a second groove 42 is opened on the top surface of the transmission box 25 for insertion into the second insertion piece 41. A second slot 43 is opened on the top surface of the second insertion piece 41 for insertion into the second insertion piece 41. An inclined surface 44 that can abut against each other is opened on the side of the second insertion piece 41 away from the threaded tube 27 and the side wall of the second slot 43 away from the threaded tube 27.

[0043] After the lifting rod 3 lifts the door panel to the specified height, the pressure plate 4 moves downward under pressure. The second plug-in piece 41 is inserted into the first plug-in piece 29 and abuts against each other with the help of the two inclined surfaces 44, so that the first plug-in piece 29 is separated from the threaded tube 27, thereby releasing the restriction on the threaded tube 27.

[0044] Reference Figure 3 and Figure 4 A rack 45 is fixed to the bottom surface of the pressure plate 4, and a sliding groove 13 is provided on the top surface of the transmission box 25, which can be inserted into the rack 45. A gear 46 that meshes with the rack 45 is rotatably installed on the side wall of the sliding groove 13 away from the threaded tube 27. The side of the gear 46 away from the threaded tube 27 is fixedly connected to the lifting rod 3. A connecting rod 31 is fixed to the bottom surface of the lifting rod 3; a suction plate 32 is fixed to the bottom surface of the connecting rod 31, and a suction plate 33 is slidably arranged along its own length. A sliding groove 34 is provided on the bottom surface of the connecting rod 31, and a motor 35 is fixed to the side wall of the sliding groove 34. A lead screw 36 is fixed to the output end of the motor 35; the lead screw 36 is rotatably arranged in the sliding groove 34; a sliding plate 12 that is threadedly engaged with the lead screw 36 is fixed to the top surface of the suction plate 33.

[0045] The lifting rod 3 adheres to the door panel via suction plates 32 and 33. After suction plate 32 adheres to the door panel, to determine the width of the door panel, i.e., the distance the lifting rod 3 needs to rise, suction plate 33 begins to move away from suction plate 32 until it reaches the side of the door panel. Motor 35 drives the lead screw 36 to rotate, thus moving suction plate 33.

[0046] Gear 46 is fixedly connected to lifting rod 3. When pressure plate 4 drives rack 45 to move downward, rack 45 meshes with gear 46 to drive gear 46 to rotate, thereby causing lifting rod 3 to rotate.

[0047] Reference Figure 4 The suction plate 2 33 has a mounting groove 1 51 on its bottom surface and a mounting groove 2 52 on its top surface, which extends along the length of the suction plate 2 33. A connecting piece 1 53 slides vertically along the suction plate 2 33 via the mounting groove 1 51. A connecting piece 2 54 slides along the length of the suction plate 2 33 via the mounting groove 2 52. A spring 2 55 is fixed to the side of the connecting piece 2 54 near the lifting rod 3. The end of the spring 2 55 away from the connecting piece 2 54 is fixedly connected to the inner wall of the mounting groove 2 52 near the lifting rod 3. Inclined surfaces 2 56 are respectively formed on the inner sides of the connecting pieces 1 53 and 2 54. A mounting groove 3 57 is formed on the top surface of the mounting groove 2 52, and a connecting piece 3 58 slides vertically along the mounting groove 3 57 via the suction plate 2 33. A slot 4 59 is formed on the top surface of the connecting piece 2 54, which can be inserted into the connecting piece 3 58. The connecting piece 3 58 near the spring 2 55 and the slot 4 59 near the spring 2 55 are respectively provided with inclined surfaces 3 5 that can abut against each other.

[0048] When the suction plate 2 33 moves to the edge of the door panel, the connecting piece 1 53 first separates from the door panel and is suspended in the air; a baffle is fixedly provided around the connecting piece 1 53 to prevent the connecting piece 1 53 from separating from the suction plate 2 33. After the connecting piece 1 53 moves downward, the spring 2 55 pushes the connecting piece 2 54 to move closer to the connecting piece 1 53, and moves upward by abutting against the connecting piece 3 58 through the inclined surface 3 5.

[0049] Reference Figure 4 An electromagnet 61 is fixed to the bottom surface of suction plate 32, and an electromagnet 62 is fixed to the bottom surface of suction plate 33. A fixed plate 63 is embedded in the bottom surface of suction plate 33, and a movable plate 64 that can make electrical contact with the fixed plate 63 is fixed to the side of connecting plate 53 near the fixed plate 63. The fixed plate 63 is electrically connected to the electromagnet 62, and the movable plate 64 is electrically connected to the power supply.

[0050] After the connecting piece 53 moves downward, the fixed piece 63 and the moving piece 64 make electrical contact, thereby connecting the electromagnet 62 to the power supply and causing the electromagnet 62 to attract the door panel.

[0051] Reference Figure 4 A number of pressing components 7 are vertically arranged on the side of the slide rail 21 away from the lifting rod 3 for pressing the pressure plate 4 downwards. Each pressing component 7 includes a sliding plate 71 that passes through the slide rail 21 and slides along the length of the lifting rod 3. An electromagnet 72 is fixed to the side of the sliding plate 71 away from the lifting rod 3, and a magnetic attractant 73 that can be attracted to the electromagnet 72 is fixed to the side of the slide rail 21 away from the lifting rod 3. Two springs 74 are fixed to the side of the electromagnet 72 near the slide rail 21. The springs 74 are made of plastic material that does not attract magnets. The side of the springs 74 away from the electromagnet 72 is fixedly connected to the side wall of the slide rail 21 away from the lifting rod 3. A connecting groove 75 is provided on the side of the sliding plate 71 near the lifting rod 3 to prevent interference with the lead screw 24.

[0052] Reference Figure 2 and Figure 4 The bottom surface of the connecting rod 31 has several fixed plates 76 evenly distributed along its length, and each fixed plate 76 is electrically connected to an electromagnet 72. The top surface of the connecting plate 58 has a movable plate 77 fixed to it, and the movable plate 77 is electrically connected to the power supply.

[0053] After the connecting piece 3 58 moves upward under pressure, the fixed piece 2 76 and the moving piece 2 77 make electrical contact, and the electromagnet 3 72 is electrically connected to the power supply. When the electromagnet 3 72 corresponding to the fixed piece 2 76 is energized, it attracts the magnetic plate 73, thereby causing the sliding plate 71 to move closer to the lifting rod 3. After the sliding plate 71 moves, it can block the transmission box 25, and by pressing down on the pressure plate 4, it causes the threaded tube 27 to lose its limiting function, thereby stopping the lifting rod 3 from rising, achieving the purpose of stopping the movement of the lifting rod 3 after it rises to a height corresponding to the width of the door panel.

[0054] The implementation principle of the preparation device and method for thermally insulated aluminum alloy doors and windows in this application embodiment is as follows:

[0055] After the lifting rod 3 attracts the door panel, motor 35 is activated. Motor 35 drives screw 36 to rotate, causing suction plate 33 to move away from suction plate 32. When suction plate 33 moves to the edge of the door panel, connecting piece 53 first separates from the door panel and is suspended. A baffle is fixed around connecting piece 53 to prevent it from separating from suction plate 33. After connecting piece 53 moves downward, spring 55 pushes connecting piece 54 closer to connecting piece 53, and it moves upward by contacting connecting piece 58 via inclined surface 5. After connecting piece 53 moves downward, fixed piece 63 and moving piece 64 make electrical contact, thus connecting electromagnet 62 to the power supply, causing electromagnet 62 to attract the door panel. The distance suction plate 33 moves corresponds to the lowest height of the lifting rod 3 from the ground when it flips.

[0056] After the connecting piece 3 58 moves upward under pressure, the fixed piece 2 76 and the moving piece 2 77 make electrical contact, and the electromagnet 3 72 is electrically connected to the power supply. After the electromagnet 3 72 corresponding to the fixed piece 2 76 is energized, it attracts the magnetic piece 73, thereby causing the slide plate 71 to move closer to the lifting rod 3. After the lifting rod 3 rises to the height of the corresponding slide plate 71, the pressure plate 4 moves downward under the pressure of the slide plate 71. The plug-in piece 2 41 is plugged into the plug-in piece 1 29 and abuts against each other with the help of the two inclined surfaces 1 44, so that the plug-in piece 1 29 is separated from the threaded tube 27, thereby releasing the restriction on the threaded tube 27; the threaded tube 27 rotates with the lead screw 1 24, and the lifting rod 3 stops rising.

[0057] Gear 46 is fixedly connected to lifting rod 3. When pressure plate 4 drives rack 45 to move downward, rack 45 meshes with gear 46 to drive gear 46 to rotate, thereby causing lifting rod 3 to rotate and completing the flipping action of door panel.

[0058] A method for preparing thermally insulated aluminum alloy doors and windows includes the following steps:

[0059] S1. Transport the door panel to be coated to the support frame 2 for coating process.

[0060] S2. After applying powder coating to the door panel surface, lower the lifting rod 3 to adsorb the door panel; after flipping the door panel, apply powder coating to the other surface of the door panel.

[0061] S3. After the powder coating is completed, lower the door panel to release the suction on the door panel and transport the door panel to the next process.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
