[0018] The positioning clamp is slidably mounted on the front and rear sides of the top of the feeding rack via an electric slider; both movable side plates have material changing ports at the bottom, and telescopic baffles are installed inside the material changing ports via an electric push rod.

[0019] Furthermore, the number and arrangement of the thermoelectric elements and electrodes of the thermoelectric conversion rack are optimized according to the size of the mixing tank and the expected energy recovery efficiency.

[0020] Furthermore, the number of adjustment frames and the snap-fit ​​method of the forming frame within the adjustment frame are adjusted according to the production scale and prefabrication process requirements of the building exterior wall panel.

[0021] Furthermore, the dimensions of the discharge rack, the length of the linear slide rail, and the movement range of the conveyor rack are designed according to the specifications of the forming frame and the convenience requirements of the material changing operation.

[0022] Furthermore, a method for producing prefabricated building exterior wall panels includes the following steps:

[0023] Turn on the raw material mixer and put the raw materials required for the production of building exterior wall panels into the mixing tank through the feed inlet. Start the mixing motor to drive the mixing device in the mixing tank to mix the raw materials. During the mixing process, the thermoelectric conversion rack works. The thermoelectric element uses the temperature difference between the inside and outside of the mixing tank to convert heat energy into electrical energy through electrodes. The thermally conductive insulation plate ensures the safe and stable operation of the thermoelectric module. After the mixing is completed, the metering feed pump at one end of the feed pipe delivers the mixed raw materials to the subsequent stages according to the set amount.

[0024] The circulating curing component of the wall panel curing equipment moves the forming frame of the building exterior wall panel to the bottom of the feeding frame. The servo electric cylinders on the front and rear sides of the top of the connecting frame are activated. The bottom of the servo electric cylinder drive shaft drives the feeding frame to move downward. The mixed raw material in the feeding pipe is transported to the inside of the forming frame through the guide pipe. The metering feeding pump at one end of the feeding pipe precisely controls the amount of raw material conveyed. After the quantitative raw material is conveyed, the vibrating rods on the front and rear sides of the bottom of the feeding frame are turned on to vibrate the raw material in the forming frame, so that the raw material is kept horizontal in the forming frame.

[0025] Start the drive motor on the front and rear drive blocks of the adjustment frame. The output shaft of the drive motor drives the drive gear to rotate in the drive groove of the drive frame. The drive gear meshes with the inner tooth groove at the bottom of the inner wall of the drive groove, so that the adjustment frame and the forming frame rotate in the curing frame. During the rotation, the level sensor inside the horizontal frame monitors the tilt angle of the adjustment frame in real time. When tilt is detected, the rotation control between the rotary table and the drive block is carried out. The rotary table adjusts the tilt angle of the adjustment frame to ensure that the adjustment frame remains horizontal when it rotates in the curing frame. At the same time, the electromagnetic heating plate at the bottom of the inner wall of the adjustment frame heats and cures the raw material in the forming frame through the heat conduction plate.

[0026] When connecting the forming frame and the adjusting frame, open the two electromagnetic plates in the movable groove inside the limiting sleeve so that they are magnetically attracted. The electromagnetic plate connected to one side of the limiting block slides into the movable groove. Place the forming frame into the adjusting frame. Disconnect the electromagnetic plates and turn on the power. Under the action of the spring, one end of the limiting block is inserted into the limiting groove inside the forming frame to complete the limiting connection. When disassembling, open the electromagnetic plates again so that they are magnetically attracted. The limiting block slides out from the limiting groove and the forming frame is taken out from the adjusting frame.

[0027] When it is necessary to replace the forming frame, activate the electric slider on the front and rear linear slide rails on the inner wall of the discharge rack to make the conveyor rack slide to the designated position on the linear slide rails. Activate the electric slider inside the conveyor rack to drive the cross rotating frame to move. Adjust the angle of the discharge rack as needed, place the forming frame to be replaced on the discharge rack, activate the electric slider on the front and rear sides of the top of the discharge rack to make the positioning clamps hold the forming frame on the front and rear sides, open the electric push rod at the material change port inside the movable side plate to make the telescopic baffle descend, and push the discharge rack with the clamped forming frame out through the material change port to complete the replacement of the old forming frame. At the same time, put the new forming frame into the curing rack for subsequent production through the same operation.

[0028] The beneficial effects achieved by the present invention using the above structure are as follows:

[0029] 1. This device is equipped with a thermoelectric conversion frame on the outer circumference of the mixing tank. The thermoelectric element uses the temperature difference between the inside and outside of the mixing tank to convert heat energy into electrical energy, realizing energy recovery, improving energy utilization efficiency, reducing production energy consumption, and conforming to the concept of green production. A metering feed pump is set at one end of the feeding pipe, which can accurately control the amount of raw materials conveyed, ensuring that the raw material ratio of each exterior wall panel is consistent, thereby improving the stability and uniformity of the exterior wall panel quality.

[0030] 2. The circulating curing component uses the meshing transmission of drive gears and drive grooves to realize the cyclic rotation of the adjustment frame and the forming frame within the curing frame. At the same time, the tilt angle of the adjustment frame is monitored and adjusted in real time using a level sensor and a rotary table to ensure that the forming frame remains horizontal during the cyclic rotation, so that the raw material is evenly distributed within the forming frame, improving the quality of the exterior wall panel. In addition, the electromagnetic heating plate at the bottom of the inner wall of the adjustment frame can heat and cure the raw material in the forming frame as needed, and can flexibly adjust the curing temperature according to the production requirements of different exterior wall panels to improve the curing effect.

[0031] 3. The adjustment frame and the forming frame are easily connected and disassembled through the cooperation of electromagnetic plates, springs, and limit blocks. The connection is simple and the disassembly does not require complicated tools, saving manpower and time and improving production efficiency. The automatic material changing component realizes the automatic replacement of the forming frame through the coordinated work of linear slide rails, electric sliders, cross rotating frames, and positioning clamps. During the material changing process, the positioning clamps can stably hold the forming frame, ensuring the safety and stability of the material changing process, reducing the risk of damage to the forming frame, and improving the continuity of production.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0044] Example 1

[0045] Please see Figures 1 to 3 As shown, a prefabrication device for producing building exterior wall panels includes:

[0046] The raw material mixer 1 includes a mixing tank 3 and a mixing motor 4. The mixing motor 4 is fixedly installed on the top of the mixing tank 3, and a feed inlet 5 is fixedly installed on the upper side of one side of the mixing tank 3. Two thermoelectric conversion frames 6 are fixedly installed on the outer circumference of the mixing tank 3. Several thermoelectric elements and electrodes are installed on the side of the two thermoelectric conversion frames 6 close to the mixing tank 3. At the same time, a heat-conducting insulating plate is installed between the inside of the thermoelectric conversion frame 6 and the surface of the mixing tank 3 to prevent short circuit between electrodes and ensure the safe and stable operation of the thermoelectric module. A feeding pipe 7 is fixedly installed at the bottom of the mixing tank 3, and a metering feeding pump is installed at one end of the feeding pipe 7.

[0047] The wall panel curing equipment 2 includes a curing frame 8 and movable side plates 29. The curing frame 8 is located in front of the raw material mixer 1, and movable side plates 29 are fixed on both sides of the curing frame 8 by bolt groups. The curing frame 8 is also equipped with a circulating curing component for the production and prefabrication of building exterior wall panels, and an automatic material changing component for the production and prefabrication of building exterior wall panels is also installed on the lower sides of both sides inside the curing frame 8.

[0048] Further explanation is needed: a connecting frame 9 is fixedly installed at the center of the top of the maintenance frame 8, and servo electric cylinders 10 are fixedly installed on the front and rear sides of the top of the connecting frame 9. One end of the feeding pipe 7 is fixedly connected to the top of the connecting frame 9, and the other end of the feeding pipe 7 extends to the bottom of the connecting frame 9. A feeding frame 11 is movably installed below the connecting frame 9, and a guide pipe 12 is fixedly installed inside the feeding frame 11. The top end of the guide pipe 12 is slidably connected to the inside of one end of the feeding pipe 7, and the bottom end of the guide pipe 12 extends to the bottom of the feeding frame 11. The front and rear sides of the top of the feeding frame 11 are fixedly connected to the bottom ends of the drive shafts of the two servo electric cylinders 10, and vibrating rods 13 are also fixedly installed on the front and rear sides of the bottom of the feeding frame 11.

[0049] It should be noted that during the prefabrication of building exterior wall panels, the forming structure of the building exterior wall panels is moved to the underside of the feeding rack 11 by the circulating curing component. The feeding rack 11 is moved downward by the drive ends of the two servo electric cylinders 10. The mixing raw materials are conveyed to the inside of the forming structure through the feeding pipe 7 and the guide pipe 12. The amount of raw materials conveyed is quantitatively controlled by the metering pump set at one end of the feeding pipe 7. After the quantitative conveying of raw materials is completed, the raw materials in the forming structure are vibrated by the two vibrating rods 13 at the bottom of the feeding rack 11 to keep the raw materials in the forming structure in a horizontal state, thereby improving the quality of subsequent prefabrication of building exterior wall panels.

[0050] Example 2

[0051] Please see Figures 4 to 6 As shown, it should be further explained that the cyclic maintenance component includes a drive frame 14, an adjustment frame 16, and a molding frame 17. The drive frame 14 is fixedly installed on the front and rear sides of the inner wall of the maintenance frame 8, and several adjustment frames 16 are movably installed between the two drive frames 14. The molding frame 17 is movably engaged inside the several adjustment frames 16, and each molding frame 17 is provided with a molding cavity inside. The inner surface of the molding cavity is coated with a layer of nanomaterial coating with superhydrophobic and self-cleaning functions.

[0052] Specifically, a rotating platform 18 is fixedly installed on both the front and rear sides of the adjustment frame 16, and a drive block 20 is rotatably installed on one side of each of the two rotating platforms 18. A horizontal frame 19 is fixedly installed on the surface of each of the two drive blocks 20, and a horizontal sensor is installed inside each of the two horizontal frames 19. A drive motor 21 is fixedly installed on one side of each of the two drive blocks 20, and a drive gear 22 is fixedly installed at one end of the output shaft of each of the two drive motors 21. A drive groove 15 is provided on the opposite side of each of the two drive frames 14 on the front and rear sides, and an internal tooth groove that cooperates with the drive gear 22 is provided at the bottom of the inner wall of each of the two drive grooves 15. The tooth surfaces of the two drive gears 22 on the front and rear sides respectively mesh with the bottom of the inner wall of the two drive grooves 15 for transmission.

[0053] It should be noted that the output shaft of the drive motor 21 controls the drive gear 22 to rotate inside the drive groove 15. The meshing transmission between the tooth surface of the drive gear 22 and the internal tooth groove at the bottom of the inner wall of the drive groove 15 allows the adjusting frame 16 and the forming frame 17 to rotate cyclically inside the curing frame 8. The rotation control between the rotary table 18 and the drive block 20, along with the level sensor inside the level frame 19, monitors the tilt angle in real time. The rotary table 18 adjusts the tilt angle of the adjusting frame 16 to maintain its horizontal state during cyclic rotation inside the curing frame 8. This enables the forming frame 17 to rotate cyclically inside the curing frame 8, allowing multiple forming frames 17 to perform cyclic curing operations inside the curing frame 8.

[0054] Furthermore, an electromagnetic heating plate is provided at the bottom of the inner wall of the adjusting frame 16, and a heat-conducting plate is provided at the top of the electromagnetic heating plate; two limiting sleeves 23 are fixedly provided on both sides of the adjusting frame 16, and each of the four limiting sleeves 23 has a movable groove inside. Two electromagnetic plates 24 are slidably arranged inside the movable groove, and one side of one electromagnetic plate 24 is fixedly connected to one side of the inner wall of the movable groove, while the other electromagnetic plate 24 is slidably connected inside the movable groove. A limiting block 27 is also fixedly provided on one side of the electromagnetic plate 24, located on the inner wall of the movable groove. A positioning slide rod 25 is fixedly provided on one side of the electromagnetic plate 24, and one end of the positioning slide rod 25 passes through another electromagnetic plate 24 and extends into the interior of the limiting block 27. A spring 26 is also fixedly provided between the opposite sides of the two electromagnetic plates 24, and the interior of the spring 26 covers the surface of the positioning slide rod 25. One end of the limiting block 27 passes through the adjustment frame 16 and extends into the interior of the adjustment frame 16. Both sides of the forming frame 17 are provided with limiting grooves 28 that cooperate with the limiting block 27, and one end of the limiting block 27 is slidably connected to the interior of the limiting groove 28.

[0055] It should be noted that when connecting the forming frame 17 and the adjusting frame 16, by activating the two electromagnetic plates 24, the two electromagnetic plates 24 are magnetically attracted to each other. The electromagnetic plate 24 connected to one side of the limiting block 27 slides into the movable groove inside the limiting sleeve 23. At this time, the forming frame 17 is placed inside the adjusting frame 16, the power supply to the electromagnetic plates 24 is disconnected, and under the action of the spring 26, one end of the limiting block 27 is inserted into the limiting groove 28 inside the forming frame 17, thus completing the limiting connection between the adjusting frame 16 and the forming frame 17. After the forming frame 17 is transferred to the bottom of the feeding rack 11, the raw materials are quantitatively fed into the interior of the forming frame 17.

[0056] Example 3

[0057] Please see Figure 3 and Figure 7 , Figure 8 As shown, further explanation is needed regarding the automatic material changing assembly, which includes a discharge rack 30 and a conveyor rack 31. Discharge racks 30 are fixedly installed on both sides inside the curing rack 8, and material changing ports are provided at the bottom of the two movable side plates 29. Telescopic baffles 36 are installed inside the material changing ports via an electric push rod. Linear slide rails 32 are fixedly installed on the front and rear sides of the inner wall of the discharge rack 30, and two conveyor racks 31 are slidably installed between the two linear slide rails 32. Cross rotating racks 33 are slidably installed inside the two conveyor racks 31 via electric sliders, and the bottom sides of the cross rotating racks 33 are rotatably connected to the top of the electric sliders. A discharge rack 34 is also movably installed on the top of the conveyor racks 31, and the bottom sides of the discharge rack 34 are rotatably connected to the front and rear sides of the top of the cross rotating racks 33. Positioning clamps 35 are slidably installed on the front and rear sides of the top of the discharge rack 34 via electric sliders. The two positioning clamps 35 clamp the replaced molding frame 17 from the front and rear sides, ensuring the stability of the molding frame 17 during the replacement process.

[0058] Example 4

[0059] Please see Figures 1 to 8 As shown, specifically, this embodiment discloses a working method for a prefabrication device for producing building exterior wall panels according to the above embodiment, including the following process:

[0060] Raw material mixing: Turn on the raw material mixer 1 and put various raw materials required for the production of building exterior wall panels into the mixing tank 3 through the feed inlet 5. Start the mixing motor 4. The mixing motor 4 drives the mixing device in the mixing tank 3 to fully mix the raw materials. During the mixing process, the thermoelectric conversion frame 6 fixed on the outer circumference of the mixing tank 3 starts to work. The thermoelectric element uses the temperature difference between the inside and outside of the mixing tank 3 to convert heat energy into electrical energy through electrodes, realizing energy recovery and utilization. At the same time, the thermally conductive insulation plate prevents short circuits between electrodes and ensures the safe and stable operation of the thermoelectric module. After the mixing is completed, the metering feed pump set at one end of the feed pipe 7 delivers the mixed raw materials to the subsequent stages according to the set amount.

[0061] Material conveying and vibration treatment for exterior wall panel forming: The circulating curing component of the wall panel curing equipment 2 moves the forming frame 17 of the building exterior wall panel to the bottom of the feeding rack 11. The servo electric cylinders 10 on the front and rear sides of the top of the connecting frame 9 are activated. The bottom end of the drive shaft of the servo electric cylinder 10 drives the feeding rack 11 to move downward. At this time, the mixing material in the feeding pipe 7 is conveyed to the inside of the forming frame 17 through the guide pipe 12 which is slidably connected to the inside of one end of the feeding pipe 7. The metering feeding pump set at one end of the feeding pipe 7 accurately controls the amount of material conveyed. After the quantitative material conveying is completed, the vibrating rods 13 on the front and rear sides of the bottom of the feeding rack 11 are turned on to vibrate the material in the forming frame 17, so that the material is kept in a horizontal state in the forming frame 17, thereby improving the quality of subsequent prefabrication of building exterior wall panels.

[0062] Cyclic curing operation: Start the drive motor 21 on the front and rear drive blocks 20 of the adjustment frame 16. The output shaft of the drive motor 21 drives the drive gear 22 to rotate in the drive groove 15 of the drive frame 14. Since the tooth surface of the drive gear 22 meshes with the inner tooth groove at the bottom of the inner wall of the drive groove 15, the adjustment frame 16 and the forming frame 17 located inside it rotate cyclically in the curing frame 8. During the cyclic rotation, the horizontal sensor inside the horizontal frame 19 monitors the tilt angle of the adjustment frame 16 in real time. When tilt is detected, the rotation table 18 and the drive block 20 are rotated. The rotation table 18 adjusts the tilt angle of the adjustment frame 16 to ensure that the adjustment frame 16 always remains horizontal when it rotates cyclically inside the curing frame 8. This realizes the cyclic curing operation of multiple forming frames 17 inside the curing frame 8. At the same time, the electromagnetic heating plate at the bottom of the inner wall of the adjustment frame 16 heats and cures the raw material in the forming frame 17 through the heat conduction plate, promotes the cement hydration reaction, and improves the strength of the building exterior wall panel.

[0063] Connection and disassembly of the molding frame and the adjusting frame: When connecting, open the two electromagnetic plates 24 in the movable groove inside the limiting sleeve 23 to generate magnetic attraction. The electromagnetic plate 24 connected to one side of the limiting block 27 slides into the movable groove. At this time, the molding frame 17 is placed inside the adjusting frame 16. Then, disconnect the power supply to the electromagnetic plate 24. Under the action of the spring 26, one end of the limiting block 27 is inserted into the limiting groove 28 inside the molding frame 17, completing the limiting connection between the adjusting frame 16 and the molding frame 17. When disassembly is required, open the electromagnetic plate 24 again to generate magnetic attraction. The limiting block 27 slides out from the limiting groove 28, and the molding frame 17 can be taken out from the adjusting frame 16.

[0064] Automatic material changing operation: When it is necessary to replace the forming frame 17, start the electric slider on the front and rear linear slide rails 32 on the inner wall of the discharge rack 30, so that the conveyor rack 31 slides on the linear slide rails 32 to the designated position. Start the electric slider inside the conveyor rack 31 to drive the cross rotating rack 33 to move. At the same time, the bottom two sides of the cross rotating rack 33 are rotatably connected to the top of the electric slider. The angle of the feeding rack 34 can be adjusted as needed. Place the forming frame 17 to be replaced on the feeding rack 34. Start the electric slider on the front and rear sides of the top of the feeding rack 34, so that the positioning clamp 35 clamps the forming frame 17 from the front and rear sides to ensure the stability of the forming frame 17 during the replacement process. Open the electric push rod at the material changing port inside the movable side plate 29, so that the telescopic baffle 36 descends and pushes the feeding rack 31 with the forming frame 17 clamped through the material changing port to complete the replacement of the old forming frame 17.

Start the mixing motor (4) to drive the mixing device in the mixing tank (3) to mix the raw materials. During the mixing process, the thermoelectric conversion rack (6) works. The thermoelectric element uses the temperature difference between the inside and outside of the mixing tank (3) to convert heat energy into electrical energy through the electrodes. The thermal insulation plate ensures the safe and stable operation of the thermoelectric module. After the mixing is completed, the mixed raw materials are transported to the subsequent links according to the set amount through the metering pump at one end of the feeding pipe (7). The circulating curing component of the wall panel curing equipment (2) moves the forming frame (17) of the building exterior wall panel to the bottom of the feeding rack (11). The servo electric cylinder (10) on the front and rear sides of the top of the connecting frame (9) is activated. The bottom end of the drive shaft of the servo electric cylinder (10) drives the feeding rack (11) to move downward. The stirring raw material in the feeding pipe (7) is transported to the inside of the forming frame (17) through the guide pipe (12). The metering feeding pump at one end of the feeding pipe (7) precisely controls the amount of raw material conveyed. After the quantitative raw material is conveyed, the vibrating rod (13) on the front and rear sides of the bottom of the feeding rack (11) is turned on to vibrate the raw material in the forming frame (17) so that the raw material is kept horizontal in the forming frame (17). Start the drive motor (21) on the front and rear drive blocks (20) of the adjustment frame (16). The output shaft of the drive motor (21) drives the drive gear (22) to rotate in the drive groove (15) of the drive frame (14). The drive gear (22) meshes with the inner tooth groove at the bottom of the inner wall of the drive groove (15) to drive the adjustment frame (16) and the forming frame (17) to rotate in the curing frame (8). During the rotation, the level sensor inside the horizontal frame (19) monitors the tilt angle of the adjustment frame (16) in real time. When the tilt is detected, the rotation table (18) and the drive block (20) are rotated to adjust the tilt angle of the adjustment frame (16) in coordination with the rotation table (18) to ensure that the adjustment frame (16) remains horizontal when it rotates in the curing frame (8). At the same time, the electromagnetic heating plate at the bottom of the inner wall of the adjustment frame (16) heats and cures the raw material in the forming frame (17) through the heat conduction plate. When connecting the molding frame (17) and the adjusting frame (16), open the two electromagnetic plates (24) in the movable groove inside the limiting sleeve (23) to make them magnetically attracted. The electromagnetic plate (24) connected to one side of the limiting block (27) slides into the movable groove. The molding frame (17) is placed inside the adjusting frame (16). The electromagnetic plate (24) is disconnected and energized. Under the action of the spring (26), one end of the limiting block (27) is inserted into the limiting groove (28) inside the molding frame (17) to complete the limiting connection. When disassembling, open the electromagnetic plate (24) again to make it magnetically attracted. The limiting block (27) slides out from the limiting groove (28) and the molding frame (17) is taken out from the adjusting frame (16). When it is necessary to replace the molding frame (17), start the electric slider on the front and rear linear slide rails (32) of the inner wall of the discharge rack (30) so that the conveyor rack (31) slides on the linear slide rails (32) to the designated position. Start the electric slider inside the conveyor rack (31) to drive the cross rotating rack (33) to move. Adjust the angle of the feeding rack (34) as needed, place the molding frame (17) to be replaced on the feeding rack (34), start the electric slider on the front and rear sides of the top of the feeding rack (34) so ​​that the positioning clamp (35) clamps the molding frame (17) from the front and rear sides. Open the electric push rod at the material changing port inside the movable side plate (29) so that the telescopic baffle (36) descends and pushes the feeding rack (34) with the molding frame (17) clamped through the material changing port to complete the replacement of the old molding frame (17). At the same time, put the new molding frame (17) into the curing rack (8) for subsequent production through the same operation.
