Description

Technical Field

[0001] The present invention relates to the technical field of concrete block forming, in particular to a forming device for energy-saving and environment-friendly autoclaved aerated blocks. Background Art

[0002] With the development trend toward energy-saving and environmentally friendly building materials, autoclaved aerated concrete blocks, a lightweight, high-strength, and energy-saving new wall material, have been widely used in modern construction projects. The molding process typically involves pouring a well-mixed concrete slurry into a mold, where it is set and initially set. The blocks are then cured in high-temperature, high-pressure steam to achieve the final physical and chemical properties.

[0003] However, during the initial setting of concrete in the mold, due to the strong adhesion between the concrete and the inner wall of the mold, it is difficult for the blocks to be smoothly removed during demolding. To alleviate this problem, the prior art generally adopts the method of spraying a release agent on the inner wall of the mold to reduce the adhesion strength. However, since the release agent is difficult to evenly adhere to the mold surface under the action of gravity, it is easy to cause uneven distribution of adhesion between the blocks and the mold. Especially in the stage where the concrete has just completed the initial setting and the strength is relatively low, if the demolding operation is not done properly, it is very easy to cause defects such as surface damage, falling off of corners, and even overall cracking of the blocks, which seriously affects the yield rate and product quality.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example 1: A molding device for energy-saving and environmentally friendly autoclaved aerated blocks, referring to Figure 1-Figure 3 As shown, it includes a workbench 1, a control panel is provided on the front of the workbench 1, a sliding frame 2 is slidingly provided on the upper part of the workbench 1, the sliding frame 2 and the workbench 1 form an upper-opening mold, the lower surface of the sliding frame 2 is set as an inclined surface, the workbench 1 is provided with a step surface, the inclined surface of the sliding frame 2 cooperates with the step surface of the workbench 1 to improve the sealing effect between the two, the workbench 1 is fixed with four first electric push rods 3 distributed in a rectangular manner, the telescopic ends of the four first electric push rods 3 are all fixed with the upper surface of the sliding frame 2, the top of the workbench 1 is fixed with a storage bin 4 for installing a switch valve, the sliding frame 2 is rotatably provided with four annular sleeves 5, the annular sleeves 5 are made of a high molecular polymer material, and are used to separate the formed building blocks from the annular sleeves 5, and the four first electric push rods 3 and the switch valves are electrically connected to the control panel.

[0020] Reference Figure 2 and Figure 3 As shown, the sliding frame 2 is fixed with four support frames 6 and four guide rollers 8, the guide rollers 8 are located below the support frames 6, the support frames 6 are rotatably provided with cylindrical rollers, the support frames 6 are installed with driving rollers 7, the driving rollers 7 are composed of rotating rollers and motors, wherein the motor is fixed with the adjacent support frames 6, the rotating rollers are rotatably connected with the adjacent support frames 6, the motor is electrically connected with the control panel, the driving rollers 7 and the cylindrical rollers on the adjacent support frames 6 clamp the adjacent annular sleeves 5, the guide rollers 8 are in contact with the outer surfaces of the adjacent annular sleeves 5, the sliding frame 2 is slidingly provided with four fixing members 9, two springs are fixed between the fixing members 9 and the sliding frame 2, the fixing members 9 are in contact with the outer surfaces of the adjacent annular sleeves 5, and the cross-section of the support frame 6 is an isosceles trapezoid.

[0021] The working process of the forming device of the energy-saving and environmentally friendly autoclaved aerated building block in this embodiment is as follows: When performing concrete block processing operations, first fill the storage bin 4 with specific concrete slurry, and then the operator starts the four first electric push rods 3 through the control panel. The telescopic end of the first electric push rod 3 pushes the sliding frame 2 down to fit the workbench 1, completing the assembly of the mold. Then the control panel starts the switch valve on the storage bin 4, and injects a specified amount of concrete slurry into the sliding frame 2. After that, the switch valve on the storage bin 4 is closed. After waiting for a period of time, the concrete slurry solidifies in the sliding frame 2. After the concrete block is initially formed, the operator starts the four first electric push rods 3 and four driving rollers 7 through the control panel. The first electric push rod 3 works to make the sliding frame 2 gradually move upward, and the driving roller 7 works to drive the annular sleeve 5 to rotate. This operation causes the concrete block to gradually separate from the sliding frame 2, completing the rapid demoulding of the concrete block, reducing damage to the concrete block, and ensuring the integrity of the finished concrete block.

[0022] At the same time, during the rotation of the annular sleeve 5, the part separated from the concrete block rotates through the cylindrical roller of the guide roller 8 and the fixing member 9, wherein the fixing member 9 cleans the debris attached to the surface of the annular sleeve 5, thereby preventing the residue from affecting the surface quality of the block during the subsequent molding process, until the sliding frame 2 is completely out of contact with the concrete block, and then the first electric push rod 3 stops working, and then the operator removes the concrete block from the workbench 1. When the concrete block is processed again later, the above operation can be repeated.

[0023] Example 2: Based on Example 1, refer to Figure 2 and Figure 4 As shown, it also includes two sliding shells 10 (this number is the number shown in the accompanying drawings, and the actual number can be adjusted accordingly as needed). The two sliding shells 10 are both slidably set on the workbench 1, and all the sliding shells 10 are commonly provided with a protective shell 11. The lower surface of the workbench 1 is fixed with two second electric push rods 12 symmetrically distributed front and back, and the telescopic ends of the two second electric push rods 12 are fixed with the protective shell 11. The two second electric push rods 12 are electrically connected to the control panel; the protective shell 11 is fixed with a vibration module 13 electrically connected to the control panel, and the vibration module 13 is used to remove bubbles from the concrete slurry.

[0024] The working process of this embodiment is similar to that of the first embodiment and is described in detail as follows: After a certain amount of concrete slurry is added to the sliding frame 2, the operator starts the second electric push rod 12 through the control panel, and the telescopic end of the second electric push rod 12 drives the protective shell 11 and the two sliding shells 10 to move upward so as to be inserted into the concrete slurry. Then the control panel starts the vibration module 13, and the vibration module 13 works to transmit the vibration force to the concrete slurry through the protective shell 11 and the two sliding shells 10 to defoam the concrete slurry. After a period of defoaming operation, the operator turns off the vibration module 13 through the control panel and controls the second electric push rod 12 to reset, wherein the telescopic end of the second electric push rod 12 drives the protective shell 11 and the two sliding shells 10 to move downward until the upper surface of the sliding shell 10 is flush with the upper surface of the workbench 1, and then stands for a period of time to wait for the concrete slurry to solidify and fix. The above operation can be repeated for subsequent demolding.

[0025] Example 3: Based on Example 2, refer to Figure 2 、 Figure 4 and Figure 5 As shown, it also includes two groups of stirring units, which are arranged on adjacent sliding shells 10. The stirring units include nine sliding rods 14, which are all slidably arranged on adjacent sliding shells 10. The nine sliding rods 14 are divided into three groups, and each group of three sliding rods 14 are circumferentially and equidistantly distributed in the horizontal direction. The sliding rods 14 in the three groups are cross-distributed. A sliding frame 15 is slidably arranged in the sliding shell 10, and a tension spring is fixed between the sliding frame 15 and the adjacent sliding shell 10. The tension spring is sleeved on the outside of the sliding frame 15, and the sliding frame 15 is provided with nine groups of inclined grooves. The inclined grooves of the sliding frame 15 are slidably connected to the adjacent sliding rods 14. In the initial state, the sliding rods 14 are retracted into the adjacent sliding shells 10. The workbench 1 is provided with a regulating component for controlling the movement of the sliding rods 14 and a driving component for controlling the rotation of all sliding shells 10.

[0026] Reference Figure 4 and Figure 5 As shown, the regulating component includes a limit frame 16, which is fixed to the lower surface of the workbench 1, and the limit frame 16 is n-shaped. The limit frame 16 is slidingly provided with a sliding plate 17 that is rotatably connected to the adjacent sliding frame 15. The limit frame 16 is provided with a convex ring for limiting the movement of the sliding plate 17, so that the sliding plate 17 and the sliding frame 15 can move relative to the adjacent sliding shell 10 at the specified position.

[0027] Reference Figure 4 and Figure 5As shown, the drive assembly includes a drive motor 18, which is installed on the lower surface of the protective shell 11 through a support. The drive motor 18 is connected to the control panel electrical appliance. The output shaft of the drive motor 18 and the adjacent sliding shell 10 are transmitted through a gear set. The two sliding shells 10 are both rotatably connected to the protective shell 11. The parts of the two sliding shells 10 located in the protective shell 11 are fixedly connected to pulleys, and a transmission belt 19 is wound around the two pulleys.

[0028] The working process of this embodiment is similar to that of the second embodiment and is described in detail as follows: During the upward movement of the sliding shell 10, the sliding shell 10 drives the adjacent sliding frame 15 and the adjacent sliding plate 17 to move upward together through the connected tension spring. When all the sliding rods 14 are located on the upper surface of the workbench 1, the sliding plate 17 continues to move upward and will contact the convex ring on the adjacent limit frame 16. Subsequently, the sliding shell 10 continues to move upward. At this time, under the limiting action of the convex ring on the limit frame 16, the sliding frame 15 and the sliding plate 17 move relative to the adjacent sliding shell 10.

[0029] During the relative movement of the sliding frame 15 and the sliding shell 10, the inclined groove on the sliding frame 15 squeezes the adjacent sliding rod 14, and the sliding rod 14 extends from the adjacent sliding shell 10. After the sliding shell 10 moves to the extreme position, the second electric push rod 12 stops working, and then the control panel starts the drive motor 18. The drive motor 18 drives the two sliding shells 10 to rotate through the gear set, pulley and transmission belt 19. The sliding shell 10 drives the sliding rod 14 to rotate to stir the concrete slurry in the sliding frame 2, fully remove the bubbles in the slurry, further improve the degassing effect, and correspondingly improve the quality of pouring.

[0030] After performing the defoaming operation for a specified time, the drive motor 18 is turned off through the control panel, and then the sliding shell 10 is controlled to move down and reset. During this process, the sliding rod 14 and the sliding shell 10 slide together to ensure that the concrete slurry in the sliding frame 2 remains unchanged, ensuring the quality of the final processed product, and then repeat the above operation to perform the demolding operation.
