[0013] (1) The conveying unit consists of a first mounting frame, a first conveying table, a first drive motor, a belt drive box, and a conveyor belt. The first drive motor drives the belt drive box, which in turn drives the conveyor belt to operate. This allows for stable and continuous conveying of fire doors, providing an orderly feeding basis for the flipping operation, ensuring the continuity of the production process, improving the conveying efficiency of fire doors, and adapting to the rhythm of automated production. The positioning and adjustment unit consists of a first fixed plate, a first mounting table, a limit plate, a slide rail, a sliding plate, a bidirectional drive motor, a threaded rod, a connecting plate, a first connecting shaft, and an adjusting rod. The bidirectional drive motor drives the threaded rod to rotate. In conjunction with the slide rail and the sliding plate, the position of the adjusting rod can be precisely adjusted to limit and position fire doors of different specifications. This ensures that the fire doors are in the correct posture before flipping, improves the flipping accuracy, avoids affecting the subsequent processing quality due to positional deviation, and enhances the adaptability of the equipment to various product specifications.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1:
[0022] Please see Figure 1-4As shown, this embodiment proposes a flipping device for fire door production. The fire door flipping device includes: a first mounting frame 1, which includes a first conveyor platform 101 fixedly connected to the upper surface of the first mounting frame 1. A first drive motor 102 is fixedly connected to one side inside the first mounting frame 1.

A pair of first fixing plates 105 are fixedly connected to both sides of the upper surface of the first conveyor platform 101. After the first drive motor 102 is powered on, it starts to run. The power generated is transmitted to the belt drive box 103 through the coupling. The belt drive box 103 converts and distributes the power, and then transmits the power to the input end of the conveyor belt 104 through the coupling, driving the conveyor belt 104 to rotate cyclically inside the first conveyor platform 101.
[0023] The second mounting bracket 2 includes a fixed bracket 201 fixedly connected to the upper surface of the second mounting bracket 2. Two pairs of connecting blocks 202 are fixedly connected to the left and right sides of one side of the fixed bracket 201. Two pairs of rotating shafts 203 are movably connected inside the two pairs of connecting blocks 202. Two pairs of pulleys 204 are fixedly connected to the outer walls of the two pairs of rotating shafts 203. A first rotating ring 205 and a second rotating ring 3 are provided on one side of the pulleys 204. A sliding groove 206 is opened inside the first rotating ring 205, and the pulley 204 is slidably connected to the inside of the sliding groove 206. A connecting column 207 is fixedly connected inside the first rotating ring 205 and the second rotating ring 3.
[0024] Preferably, a first mounting platform 106 is fixedly connected to the upper surface of the first fixed plate 105. Limiting plates 107 are fixedly connected to the left and right sides of the upper surface of the first mounting platform 106. Slide rails 108 are provided on the left and right sides of the limiting plates 107. A sliding plate 109 is slidably connected to the upper surface of the slide rails 108. A bidirectional drive motor 1010 is fixedly connected to the upper surface of the first mounting platform 106. Threaded rods 1011 are fixedly connected to the output ends of the bidirectional drive motor 1010 on the left and right sides. The threaded rods 1011 penetrate the interior of the sliding plate 109 and are connected to the limiting plates 107. Connecting plates 1012 are fixedly connected to the front and rear sides of the sliding plate 109. A first connecting shaft 101 is movably connected to the lower surface of the connecting plate 1012. 3. An adjusting rod 1014 is fixedly connected to the lower surface of the first connecting shaft 1013. When the bidirectional drive motor 1010 starts, its left and right output ends rotate, driving the threaded rod 1011 to rotate. Since the threaded rod 1011 passes through the sliding plate 109 and is connected to the limiting plate 107, under the limiting guidance of the slide rail 108, the sliding plate 109 will move horizontally towards or away from each other along the slide rail 108. When the sliding plate 109 moves, the adjusting rod 1014 moves synchronously through the connecting plate 1012 and the first connecting shaft 1013. The adjusting rod 1014 can perform position adjustment and limiting operations on the fire door placed on the first conveyor table 101, such as accurately positioning the fire door to the position required for subsequent flipping and other processes.
[0025] Preferably, a connecting frame 208 is fixedly connected to one side of the connecting column 207, a first placement platform 209 is fixedly connected to one side of the connecting frame 208, a first air pump 2010 is fixedly connected to the upper surface of the first placement platform 209, a first guide rod 2011 is movably connected to the front and rear sides inside the first placement platform 209, a descending plate 2012 is fixedly connected to the lower surface of the first guide rod 2011, a plurality of connecting rods 2013 are fixedly connected to the lower surface of the descending plate 2012, a second fixing plate 2014 is fixedly connected to the lower surface of the connecting rods 2013, and the left and right sides of the lower surface of the second fixing plate 2014 are fixedly connected to... A pair of rolling plates 2015 are fixedly connected. Several conveyor shafts 2016 are arranged inside the pair of rolling plates 2015. A second mounting platform 2017 is fixedly connected to one side of a first placement platform 209. A second drive motor 2018 is fixedly connected to one side of the second mounting platform 2017. A first rotating gear 2019 is fixedly connected to the output end of one side of the second drive motor 2018. A second connecting shaft 2020 is fixedly connected to one side of the several conveyor shafts 2016. A second rotating gear 2021 is fixedly connected to the outer wall of the second connecting shaft 2020. The first rotating gear 2019 and the second rotating gear 2021... The outer wall of component 1 is fixedly connected to a first transmission chain 2022 via teeth. A third rotating gear 2023 is fixedly connected to the outer wall of several second connecting shafts 2020. The outer wall of the third rotating gear 2023 is fixedly connected to a second transmission chain 2024 via teeth. This chain is started by a second drive motor 2018, whose output drives the first rotating gear 2019 to rotate. The first rotating gear 2019 drives the second rotating gear 2021 to rotate via the first transmission chain 2022, thereby causing the second connecting shafts 2020 to rotate synchronously. The third rotating gear 2023 on the outer wall of the second connecting shaft 2020 is connected to the second transmission chain 2024 via teeth. The moving chain 2024 drives the other second connecting shafts 2020 to rotate, ultimately achieving synchronous rotation of all conveying shafts 2016. When the conveying shafts 2016 rotate, they can move the fire door. When it is necessary to adjust the relative position of the conveying shafts 2016 and the fire door, the first air pump 2010 works. Under the guidance of the first guide rod 2011, it drives the lowering plate 2012 to move up and down. The lowering plate 2012 drives the second fixed plate 2014 and the rolling plate 2015 to move up and down through the connecting rod 2013, thereby adjusting the height of the conveying shaft 2016 so that it can better contact the fire door and carry out the conveying operation.
[0026] Preferably, a synchronous gear 301 is fixedly connected inside the second rotating ring 3, a fixed platform 302 is fixedly connected to the upper surface of the second mounting bracket 2, a first servo motor 303 is fixedly connected to the upper surface of the fixed platform 302, a third connecting shaft 304 is fixedly connected to one output end of the first servo motor 303, and a meshing gear 305 is fixedly connected to one output end of the third connecting shaft 304. The meshing gear 305 meshes with the synchronous gear 301 through its teeth. The first servo motor 303 starts and outputs power, which is transmitted through the output end of the first servo motor 303. The signal is transmitted to the third connecting shaft 304, causing the third connecting shaft 304 to rotate synchronously. Since the output end on one side of the third connecting shaft 304 is fixedly connected to the meshing gear 305, the meshing gear 305 will rotate together with the third connecting shaft 304. The meshing gear 305 meshes with the synchronous gear 301 through its teeth. The rotation of the meshing gear 305 will drive the synchronous gear 301 to rotate through the meshing action between the teeth. The synchronous gear 301 is fixedly connected inside the second rotating ring 3, so the rotation of the synchronous gear 301 will directly drive the second rotating ring 3 to rotate as a whole.
[0027] Preferably, a second placement platform 4 is fixedly connected to both sides of the connecting column 207. A second guide rod 401 is movably connected to both sides of the second placement platform 4. A second air pump 402 is fixedly connected to one side of the second placement platform 4. Air rods 403 are fixedly connected to the output ends of both the second air pump 402 and the first air pump 2010. A clamping plate 404 is attached to one side of the air rod 403, and one side of the clamping plate 404 is connected to the output end of the second guide rod 401. A second conveying platform 405 is fixedly connected to one side of the connecting column 207. A rotating shaft 406 is movably connected inside the second conveying platform 405. A pair of conveyor chains 407 are fixedly connected to the outer wall. A second servo motor 408 is fixedly connected to one side of the second conveyor table 405. The second servo motor 408 is connected to the input end of the rotating shaft 406 through a coupling. When clamping the fire door, the second air pump 402 is started, and its output end pushes the air rod 403 to extend and retract. Since the clamping plate 404 is fixedly connected to the air rod 403, and one side of the clamping plate 404 is connected to the output end of the second guide rod 401, the extension and retraction of the air rod 403 will drive the clamping plate 404 to move along the direction of the second guide rod 401, thereby realizing the clamping or releasing action of the clamping plate 404 on the fire door. The working logic of the first air pump 2010 is the same as that of the second air pump 402. It drives the corresponding clamping plate 404 to move through the air rod 403, and works together to stably clamp the fire door. When the fire door is being transported, the second servo motor 408 is started. Its output end drives the rotating shaft 406 to rotate through the coupling. When the rotating shaft 406 rotates, it drives the conveyor chain 407 on the outer wall to move in a cycle. After the conveyor chain 407 comes into contact with the fire door, it drives the fire door to move through friction, thus realizing the conveying function of the fire door.
[0028] In use, the first drive motor 102 is first powered on and the power is transmitted to the belt drive box 103 via the coupling. After the belt drive box 103 converts and distributes the power, it drives the conveyor belt 104 in the first conveyor table 101 to rotate cyclically through the coupling. The fire door is placed on the conveyor belt 104, and the conveyor belt 104 will transport the fire door to the relevant area for subsequent flipping. At the same time, the bidirectional drive motor 1010 is started, and its left and right output ends drive the threaded rod 1011 to rotate. Under the limiting guidance of the slide rail 108, the sliding plate 109 moves horizontally towards or away from each other along the slide rail 108. The sliding plate 109 drives the adjusting rod 1014 to move synchronously through the connecting plate 1012 and the first connecting shaft 1013. The adjusting rod 1014 adjusts and limits the position of the fire door on the conveyor belt 104, and accurately positions it to the position required for the subsequent flipping process.
[0029] When the fire door is transported to the corresponding position, the second drive motor 2018 starts, and the output end drives the first rotating gear 2019 to rotate. The first rotating gear 2019 drives the second rotating gear 2021 to rotate through the first transmission chain 2022, thereby causing the second connecting shaft 2020 to rotate synchronously. The third rotating gear 2023 on the outer wall of the second connecting shaft 2020 drives the other second connecting shafts 2020 to rotate through the second transmission chain 2024. All the conveying shafts 2016 rotate synchronously to further transport the fire door. If the relative position of the conveying shaft 2016 and the fire door needs to be adjusted, the first air pump 2010 works. Under the guidance of the first guide rod 2011, it drives the descending plate 2012 to move up and down. The descending plate 2012 drives the second fixed plate 2014 and the rolling plate 2015 to move up and down through the connecting rod 2013, thereby adjusting the height of the conveying shaft 2016 so that it can better contact and transport the fire door.
[0030] When the fire door reaches the designated flipping position, the second air pump 402 starts, and the output end pushes the air rod 403 to extend and retract. Since the clamping plate 404 is fixedly connected to the air rod 403 and one side is connected to the output end of the second guide rod 401, the extension and retraction of the air rod 403 drives the clamping plate 404 to move along the direction of the second guide rod 401, thereby clamping the fire door. The first air pump 2010 drives the corresponding clamping plate 404 to move in the same way, and works together to clamp the fire door, ensuring that the fire door will not loosen or shift during the flipping process.
[0031] After clamping is completed, the first servo motor 303 starts to output power. The power is transmitted to the meshing gear 305 through the third connecting shaft 304, which drives the meshing gear 305 to rotate. The meshing gear 305 meshes with the synchronous gear 301 inside the second rotating ring 3 through its teeth, driving the synchronous gear 301 to rotate. The synchronous gear 301 drives the second rotating ring 3 to rotate as a whole. Since the second rotating ring 3 and the first rotating ring 205 are fixedly connected by the connecting column 207, the rotation of the second rotating ring 3 will drive the first rotating ring 205 and the connecting column 207 to rotate together. The relevant components connected to the connecting column 207 and the clamped fire door also rotate accordingly, realizing the flipping of the fire door. During this process, the rotating shaft 203 in the connecting block 202 on the fixing frame 201 drives the pulley 204 to slide in the sliding groove 206 of the first rotating ring 205, providing stable support and guidance for the rotation of the rotating ring.
[0032] After the fire door is flipped, the clamping plate 404 releases the fire door under the action of the air pump. The second servo motor 408 starts, and the output end drives the rotating shaft 406 in the second conveyor table 405 to rotate through the coupling. The rotating shaft 406 drives the conveyor chain 407 on the outer wall to move in a cycle. After the conveyor chain 407 contacts the fire door, it drives the flipped fire door to move through friction and transport it to the next process.
