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

[0030] The purpose of this invention is to provide a foamed board production device to solve the problems existing in the prior art. The process is simpler, the production efficiency is higher, and the equipment investment and space occupied are greatly reduced.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 8 As shown, this embodiment provides a foamed board production apparatus, including a mold support frame 10 and several mold frames 11, each with a U-shaped cross-section. The U-shaped openings of two mold frames 11 are aligned and fitted together to form a mold body with a top opening and a bottom opening. The mold frame 11 is connected to a mold power mechanism capable of driving it to move horizontally. The mold power mechanism consists of a mold hydraulic component 12 and a connecting bracket 13. The connecting bracket 13 connects the output end of the mold hydraulic component 12 and the mold frame 11. The foamed board production apparatus also includes a mixing and grouting mechanism for injecting grout into the mold body, a top sealing mechanism, and a trolley 3. 0. The top sealing mechanism includes a top plate 20 support frame, a top plate 20 set on the top plate 20 support frame, a mold pressure head 21 set at the bottom of the top plate 20, and a top plate 20 power mechanism that drives the top plate 20 to rise and fall. The top plate 20 is detachably connected to the mold support frame 10. The shape of the mold pressure head 21 is adapted to the cavity of the mold body and is used to pressurize and seal the top of the mold body. The trolley 30 includes a support plate 31 and rollers 32 located at the bottom of the support plate 31. The upper surface of the support plate 31 is provided with a boss 33. The shape of the boss 33 is adapted to the cavity of the mold body and is used to seal the bottom opening of the mold body.

[0033] In use, the mold hydraulic assembly 12 drives the connecting bracket 13 to move, so that the mold frames 11 are aligned and fitted together to form a cylindrical mold body. The boss 33 seals the bottom opening of the mold body. The mixing and grouting mechanism injects the mixed slurry into the cavity of the mold body. The power mechanism of the top plate 20 drives the top plate 20 to descend. The mold pressure head 21 seals the top opening of the mold body and connects the top plate 20 to the mold support frame 10 to ensure the stability of the top plate 20. The slurry is statically pressed in the mold body. At the same time, the temperature of the static pressure environment can be adjusted to improve the molding quality of the foam board. After static pressure for a certain period of time, the mold hydraulic component 12 is activated, which drives the two mold frames 11 to move towards each other through the connecting bracket 13. The mold body opens, realizing demolding. Of course, for easy demolding, the inner surface of the mold frame 11 is pre-set with demolding filter cloth. After demolding, the power mechanism of the top plate 20 drives the top plate 20 and the mold support frame 10 to rise until the mold frame 11 is completely separated from the foam board. The foam board is left on the pallet 31. Finally, the trolley 30 is pulled to the stacking yard. The clamping machine 54 unloads the foam board from the pallet 31, and the stacking machine 55 stacks the foam board neatly, completing the prefabrication of the foam board.

[0034] Therefore, this embodiment replaces the traditional horizontal mold with a vertical mold, which not only allows for the simultaneous prefabrication of foamed boards using multiple mold bodies, but also eliminates the traditional foamed board cutting process. Different mold frames 11 can be used to prefabricate foamed boards according to their model and size, simplifying the process, increasing production efficiency, and significantly reducing equipment investment and space requirements. Furthermore, this embodiment directly uses the boss 33 on the trolley 30 to seal the bottom opening of the mold body. After demolding, the trolley 30 can directly transport the foamed boards to the palletizing yard without needing to move them back onto the trolley 30, thus saving loading time and improving production and transportation efficiency.

[0035] In this embodiment, multiple connecting brackets 13 are provided. Preferably, one connecting bracket 13 connects two mold frames 11 arranged back to back. The connecting bracket 13 can be any structural form that can drive the mold frame 11 to translate. The specific structure will not be described in detail in this embodiment.

[0036] To prevent the vertical foam board from tipping over after demolding, baffles 34 are provided at both ends of the support plate 31 in this embodiment to block the foam board in the direction of tipping.

[0037] Furthermore, in this embodiment, the top plate 20 support frame includes a base column 29 and a base beam 210 connecting the base column 29. The base column 29 has a cavity inside. A guide column 22 is slidably disposed in the cavity at the bottom of the top plate 20. The output end of the power mechanism of the top plate 20 extends into the cavity and is connected to the guide column 22 for transmission. The power mechanism of the top plate 20 includes a top plate hydraulic assembly 28. The output end of the top plate hydraulic assembly 28 is connected to the guide column 22. Several screws 23 are also installed on the top plate 20. Nuts 24 are connected to the top ends of the screws 23, which are positioned above the top plate 20 to prevent the screws 23 from detaching. The bottom ends of the screws 23 are connected to the pressure plate 211. Compression springs 25 are also fitted onto the screws 23, with both ends connected to the top plate 20 and the pressure plate 211 respectively. A mold pressure head 21 is provided on the lower surface of the pressure plate 211. When the mold pressure head 21 is inserted into the mold body, the pressure head moves upward under the reaction force of the slurry, compressing the springs 25. Simultaneously, the pressure head also presses the slurry tightly under the elastic force of the spring, ensuring... The slurry is effectively compressed, and the screw 23 can be moved up and down on the top plate 20 by rotating the nut 24 to adjust the force applied to the slurry. To ensure that the pressure plate 211 can move vertically without shaking, the pressure plate 211 has through holes at both ends, through which a guide rod fixed to the bottom of the top plate 20 is inserted. The bottom end of the mold pressure head 21 is provided with an arc groove or arc protrusion 35, and the support plate 31 is correspondingly provided with an arc protrusion 35 or arc groove. The arc protrusion 35 and the arc groove are matched in shape, which can form a groove and a protrusion at the end of the foam board, which is convenient for splicing the foam board during construction.

[0038] To facilitate the positioning of the top plate 20, mold support frame 10, and pallet 31, in this embodiment, the mold support frame 10 includes an upper support beam 14, a lower support beam 15, and support columns 110 connecting the two. The upper support beam 14 is provided with a plurality of top plate positioning holes 111, and the top plate 20 is provided with a plurality of top plate positioning posts 26 for corresponding insertion into the top plate positioning holes 111. The lower support beam 15 is provided with a plurality of support frame positioning posts 112, and the pallet 31 is provided with a plurality of support frame positioning holes 37 for corresponding insertion into the support frame positioning posts 112. Furthermore, the upper support beam 14 is also provided with a plurality of top plate locking posts 16, and the top plate 20 is provided with a plurality of top plate locking hooks 27 for connecting the top plate locking posts 16. The lower support beam 15 is also provided with a plurality of support frame locking hooks 17, and the pallet 31 is provided with a plurality of support frame locking posts 36 for connecting the support frame locking hooks 17.

[0039] To ensure the static pressure molding temperature of the foamed board, the foamed board production device in this embodiment also includes a hot water circulation system. The hot water circulation system is equipped with hot water flow pipes. The mold frame 11 is welded from metal plates, and the wall of the mold frame 11 is made of at least two metal plates. The hot water flow pipes are located in the sandwich of the metal plates for heating the mold frame 11. Meanwhile, a hot water inlet pipe 18 and a hot water outlet pipe 19 are respectively installed in the upper support beam 14 and lower support beam 15 of the support frame. Holes are opened on both the upper support beam 14 and lower support beam 15, and corrugated pipes are installed in these holes. The corrugated pipes connect the hot water inlet pipe 18 to the hot water flow pipes, and the hot water outlet pipe 19 to the hot water flow pipes. The water supply is not affected when the mold frame 11 moves horizontally. Furthermore, the power of the second hot water pump 53 in the hot water circulation system is adjustable. A temperature sensor is installed inside the mold frame 11 to monitor the heating temperature. By adjusting the power of the second hot water pump 53, the temperature of the mold frame 11 is stably controlled, typically within the range of 55℃-95℃.

[0040] The mixing and grouting mechanism includes a mixing and slurry preparation tank 40, a grouting pump 41, a foaming agent tank 42, and a mixing and homogenizing tank 43 connected in sequence. The inlet of the mixing and slurry preparation tank 40 is connected to the raw material powder silo 45 via a screw feeder 44. Multiple raw material powder silos 45 can be provided, and each raw material powder silo 45 is equipped with a corresponding screw feeder 44 to achieve quantitative feeding. The outlet of the mixing and slurry preparation tank 40 is connected to the inlet 46 of the mixing and homogenizing tank 43 via a first drain valve and the grouting pump 41. The mixing and slurry preparation tank 40 is also connected to a water supply pipe 48 and is equipped with a first agitator. The foaming agent tank 42 is connected to the foaming agent silo via a screw feeder 44 and a water supply pipe 48 via a water supply valve 47. A third agitator 49 is installed in the foaming agent tank 42, and its bottom is connected to the mixing and homogenizing tank 43 via a third drain valve 410. A foaming agent level gauge 411 is installed in the foaming agent tank 42 to control the metering of the foaming agent. The mixing and homogenizing tank 43 contains a second agitator 412 and a slurry level gauge 416. The outlet of the mixing and homogenizing tank 43 is connected to a main grouting pipe 414 via a second drain valve 413. The main grouting pipe 414 is connected to several branch grouting pipes, each corresponding to a mold body. Furthermore, the main grouting pipe 414 and the second drain valve 413 can be connected via a bellows pipe to facilitate the movement of the main grouting pipe 414 for grouting. After grouting is completed, the branch grouting pipes 415 are removed, allowing the mold pressure head 21 to be inserted into the top of the mold body for sealing.

[0041] Those skilled in the art should understand that a controller 56 is also provided in this embodiment, and the controller 56 is electrically connected to the screw feeder 44, the top plate hydraulic assembly 28, the mold hydraulic assembly 12, etc.

[0042] This embodiment also provides a method for using a foaming production device, including the following steps:

[0043] The first step is pulping. First, turn on the first water heater 50 and the second water heater 51 to prepare hot water at the set temperature. Simultaneously, turn on the agitator of the pulping tank 40, and then turn on the first hot water pump 52 to inject hot water into the pulping tank 40. After reaching the predetermined water level, turn off the first hot water pump 52. Place different raw materials into different raw material powder silos 45, and then turn on the screw feeders 44 to feed the pulping materials into the pulping tank 40 in a measured amount. When the raw material feed rate meets the preset feed rate, stop the corresponding screw feeder 44 and allow the pulping process to continue for 0.5 to 1 hour before use.

[0044] The second step is grouting. First, place the trolley 30 under the mold support frame 10. Then, start the top plate hydraulic assembly 28 to drive the top plate 20 and the mold support frame 10 downwards, and orient the mold body onto the pallet 31 of the transport trolley 30, so that the pallet 31 and the mold frame 11 form a mold body that can be grouted. Then, lock the support frame locking hook 17 and the support frame locking column 36. Open the lock between the top plate locking hook 27 and the top plate locking column 16, and start the top plate hydraulic assembly 28 to raise the top plate 20 away from the mold support frame 10 to facilitate grouting. Start the second heating pump to introduce hot water into the hot water circulation channel inside the mold frame 11 to heat the mold frame 11 and make the mold frame 11 reach the predetermined temperature. Then start... Start the grouting pump 41 to input the slurry in the mixing and slurry preparation tank 40 into the mixing and homogenizing tank 43 through the slurry inlet 46. When the slurry reaches the predetermined liquid level, turn off the grouting pump 41 and turn on the second agitator 412 in the mixing and homogenizing tank 43 to mix and homogenize the slurry. Then, open the foaming tank drain valve and add the pre-made foaming agent into the mixing and homogenizing tank 43 at once. Stir at high speed for 30 seconds to make the foaming agent and slurry completely and thoroughly mixed. Immediately open the second drain valve 413 so that all the slurry in the mixing and homogenizing tank 43 flows quickly into the grouting main pipe 414. Then, it is evenly distributed into the grouting branch pipes through the grouting main pipe 414 and finally injected into the mold body from the corresponding grouting branch pipes to complete the grouting.

[0045] The third step is static pressure foaming and curing. After grouting is completed, the top plate hydraulic assembly 28 is activated, the top plate 20 is lowered, and the mold pressure head 21 is inserted into the mold body below it and reaches the preset position. The top plate hydraulic assembly 28 is then stopped, and the top plate locking hook 27 is locked with the top plate locking column 16. The grout is statically pressed in the mold groove for 6 to 8 hours to complete the static pressure foaming and curing process.

[0046] The fourth step is demolding, unloading, and stacking. After the static pressure foaming and curing process is completed, first, open the locking hooks 27 and 16 of the top plate, then activate the hydraulic assembly 28 of the top plate to move the top plate 20 upward, causing the mold pressure head 21 to detach from the mold body; then activate the hydraulic assembly 12 of the mold to move the connecting bracket 13 and the mold frame 11 horizontally closer to each other, causing the mold body and the finished foamed board to separate horizontally from the mold frame 11, thus achieving demolding; finally, open the locking hooks 17 and 36 of the support frame. The locking mechanism is activated, and the top plate hydraulic assembly 28 is opened, causing the top plate 20 to descend. The top plate locking hook 27 is then locked to the top plate locking post 16. The top plate hydraulic assembly 28 is then activated again, causing the top plate 20 and mold support frame 10 to rise together, disengaging the mold frame 11 from the pallet 31. The traction machine of the trolley 30 is then started, transporting the finished foamed boards from the trolley 30 and pallet 31 to the stacking yard. With the cooperation of the clamping machine 54 and the stacking machine 55, the transfer and stacking of the finished foamed boards are completed. This completes the entire production process. This cyclical operation forms a continuous and stable industrial production process.

[0047] Any adaptive changes made according to actual needs are within the scope of protection of this invention.
