Description

Technical Field

[0001] This invention relates to the field of concrete block molding technology, and in particular to a molding device for energy-saving and environmentally friendly autoclaved aerated concrete blocks. Background Technology

[0002] With the development trend of energy-saving and environmentally friendly building materials, autoclaved aerated concrete (AAC) blocks, as a lightweight, high-strength, and energy-saving new type of wall material, have been widely used in modern construction projects. The molding process typically includes: injecting uniformly mixed concrete slurry into molds, where it is shaped and initially set; subsequently, the initially set blocks are cured with high-temperature, high-pressure steam to complete the final formation of their physicochemical properties.

[0003] However, during the initial setting of concrete within the mold, the strong adhesion between the concrete and the inner wall of the mold makes it difficult for the blocks to detach smoothly during demolding. To alleviate this problem, existing technologies typically employ spraying a release agent onto the inner wall of the mold to reduce adhesion strength. However, because the release agent is difficult to adhere evenly to the mold surface under gravity, it easily leads to uneven distribution of adhesion between the blocks and the mold. Especially in the stage when the concrete has just completed its initial setting and its strength is low, improper demolding operations can easily cause defects such as surface damage, edge detachment, and even overall cracking of the blocks, seriously affecting the yield and product quality. Summary of the Invention

[0004] To overcome the problems mentioned above, the present invention provides an energy-saving and environmentally friendly autoclaved aerated concrete block forming device.

[0005] The technical implementation of the present invention is as follows: an energy-saving and environmentally friendly autoclaved aerated concrete block forming device, comprising a workbench, a control panel on the workbench, a sliding frame slidably mounted on the workbench, the sliding frame and the workbench forming an open-top mold, a first electric push rod fixedly connected to the workbench, the telescopic end of the first electric push rod fixedly connected to the sliding frame, a storage bin fixedly connected to the top of the workbench, a switch valve mounted at the bottom of the storage bin, and four annular sleeves rotatably mounted on the sliding frame, the annular sleeves being made of high molecular polymer material for separating the formed block from the annular sleeves, the first electric push rod and the switch valve on the storage bin being electrically connected to the control panel on the workbench.

[0006] Preferably, the lower surface of the sliding frame is set as an inclined surface, and the worktable is provided with a stepped surface. The inclined surface of the sliding frame cooperates with the stepped surface of the worktable to improve the sealing effect between the two.

[0007] Preferably, the sliding frame is fixedly connected to four support frames and four guide rollers. The support frames are rotatably equipped with cylindrical rollers and drive rollers. The drive rollers and the cylindrical rollers on the adjacent support frames clamp the adjacent annular sleeves. The guide rollers are in contact with the outer surface of the adjacent annular sleeves. The drive rollers are electrically connected to the control panel of the worktable.

[0008] Preferably, the sliding frame is slidably provided with four fixing members, and a spring is fixed between the fixing members and the sliding frame. The fixing members are in contact with the outer surface of the adjacent annular sleeve.

[0009] Preferably, the system further includes two sliding shells, both of which are slidably disposed on the worktable. All the sliding shells are provided with a protective shell. A second electric push rod is fixedly connected to the lower surface of the worktable. The telescopic end of the second electric push rod is fixedly connected to the protective shell. The second electric push rod is electrically connected to the control panel of the worktable.

[0010] Preferably, the protective shell is fixedly connected to a vibration module, and the vibration module is electrically connected to the control panel of the workbench.

[0011] Preferably, the system further includes two sets of agitation units, each agitated on an adjacent sliding shell. Each agitation unit includes multiple sliding rods, all of which are slidably disposed on the adjacent sliding shell. Each sliding shell is slidably provided with a sliding frame, and a tension spring is fixedly connected between the sliding frame and the adjacent sliding shell. The sliding frame is provided with multiple sets of tilting grooves, and the tilting grooves of the sliding frame are slidably connected to the adjacent sliding rods. The worktable is provided with a control component and a drive component. The control component is used to control the movement of the sliding rods, and the drive component is used to control the rotation of all the sliding shells.

[0012] Preferably, the multiple sliding rods on the same sliding shell are distributed in a crisscross pattern.

[0013] Preferably, the control component includes a limiting frame, which is fixedly connected to the worktable. The limiting frame is slidably provided with a sliding plate, which is rotatably connected to an adjacent sliding frame. The limiting frame is provided with a protruding ring for restricting the movement of the sliding plate.

[0014] Preferably, the drive assembly includes a drive motor, which is mounted on the protective shell via a support. The drive motor is electrically connected to the control panel of the workbench. The output shaft of the drive motor is driven by a gear set to the adjacent sliding shell. Both sliding shells are rotatably connected to the protective shell. A transmission belt is wound around the two sliding shells via a pulley, and the transmission belt is located inside the protective shell.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. This invention assists in the separation of concrete blocks from the sliding frame by rotating the annular sleeve, quickly completing the demolding operation of concrete blocks and reducing damage to the concrete blocks, ensuring the integrity of the finished concrete blocks. At the same time, this structure can also effectively reduce the amount of release agent used, and even achieve demolding without release agent in some cases, thereby reducing production costs and reducing environmental impact.

[0017] 2. The cleaning of the outer surface of the annular sleeve by the fixing component facilitates the continuous preparation of concrete blocks by this device, and avoids the impact of residue on the surface quality of the blocks during the subsequent molding process.

[0018] 3. The second electric push rod is inserted into the concrete, and in conjunction with the operation of the vibration module, the concrete slurry in the sliding frame is defoamed to ensure the quality of the finished concrete blocks. At the same time, the second electric push rod moves downward to avoid bringing out the concrete slurry in the sliding frame, thereby ensuring the dimensional accuracy of the concrete blocks.

[0019] 4. The sliding shell drives the sliding rod to rotate, which agitates the concrete slurry, effectively removing air bubbles and further improving the defoaming effect, thereby improving the quality of the pouring. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0027] Example 1: A molding device for energy-saving and environmentally friendly autoclaved aerated concrete blocks, referring to... Figures 1-3 As shown, the device includes a workbench 1, a control panel at the front of the workbench 1, a sliding frame 2 slidably mounted on the upper part of the workbench 1, the sliding frame 2 and the workbench 1 forming an open mold, the lower surface of the sliding frame 2 being an inclined surface, and the workbench 1 having a stepped surface. The inclined surface of the sliding frame 2 and the stepped surface of the workbench 1 cooperate to improve the sealing effect between them. Four rectangularly distributed first electric push rods 3 are fixedly connected to the workbench 1, and the telescopic ends of the four first electric push rods 3 are all fixedly connected to the upper surface of the sliding frame 2. A storage bin 4 for installing a switch valve is fixedly connected to the top of the workbench 1. Four annular sleeves 5 are rotatably mounted on the sliding frame 2. The annular sleeves 5 are made of high molecular polymer material and are used to separate the molded blocks from the annular sleeves 5. The four first electric push rods 3 and the switch valve are all electrically connected to the control panel.

[0028] Reference Figure 2 and Figure 3 As shown, the sliding frame 2 is fixedly connected to 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 equipped with cylindrical rollers. The support frames 6 are equipped with drive rollers 7, which consist of rotating rollers and motors. The motor is fixedly connected to the adjacent support frame 6, and the rotating rollers are rotatably connected to the adjacent support frames 6. The motor is electrically connected to the control panel. The drive 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 surface of the adjacent annular sleeves 5. The sliding frame 2 is slidably equipped with four fixing parts 9. Two springs are fixedly connected between the fixing parts 9 and the sliding frame 2. The fixing parts 9 are in contact with the outer surface of the adjacent annular sleeves 5. The cross-section of the support frame 6 is an isosceles trapezoid.

[0029] The working process of the energy-saving and environmentally friendly autoclaved aerated concrete block forming device in this embodiment is as follows:

[0030] During the concrete block processing operation, a specific concrete slurry is first filled into the storage silo 4. Then, the operator activates four first electric push rods 3 via the control panel. The telescopic ends of the first electric push rods 3 push the sliding frame 2 down to fit against the worktable 1, completing the mold assembly. Next, the control panel activates the switch valve on the storage silo 4 to inject a specified amount of concrete slurry into the sliding frame 2. After that, the switch valve on the storage silo 4 is closed. After a period of time, the concrete slurry solidifies in the sliding frame 2. After the concrete block is initially formed, the operator activates the four first electric push rods 3 and four drive rollers 7 via the control panel. The operation of the first electric push rods 3 causes the sliding frame 2 to gradually move upward, while the operation of the drive rollers 7 drives the annular sleeve 5 to rotate. This operation causes the concrete block to gradually detach from the sliding frame 2, completing the rapid demolding of the concrete block, reducing damage to the concrete block, and ensuring the integrity of the finished concrete block.

[0031] Meanwhile, during the rotation of the annular sleeve 5, the part that has separated from the concrete block rotates through the cylindrical roller of the guide roller 8 and the fixing part 9. The fixing part 9 cleans the debris attached to the surface of the annular sleeve 5, preventing the residue from affecting the surface quality of the block during the subsequent molding process, until the sliding frame 2 completely detaches from the contact with the concrete block. Then the first electric push rod 3 stops working, and the operator removes the concrete block from the workbench 1. When processing concrete blocks again, the above operation can be repeated.

[0032] Example 2: Based on Example 1, referring to... Figure 2 and Figure 4 As shown, it also includes two sliding shells 10 (this number is shown in the attached figure, and the actual number can be adjusted accordingly as needed). Both sliding shells 10 are slidably mounted on the workbench 1. All sliding shells 10 are provided with a protective shell 11. Two second electric push rods 12 are fixedly connected to the lower surface of the workbench 1, which are symmetrically distributed front and back. The telescopic ends of the two second electric push rods 12 are fixedly connected to the protective shell 11. Both second electric push rods 12 are electrically connected to the control panel. A vibration module 13, which is electrically connected to the control panel, is fixedly connected to the protective shell 11. The vibration module 13 is used to remove air bubbles from the concrete slurry.

[0033] The working process of this embodiment follows that of Embodiment 1, and is described in detail as follows:

[0034] After a measured amount of concrete slurry is added into the sliding frame 2, the operator activates the second electric push rod 12 via the control panel. The telescopic end of the second electric push rod 12 moves the protective shell 11 and the two sliding shells 10 upwards, inserting them into the concrete slurry. Subsequently, the control panel activates the vibration module 13, which transmits vibration force through the protective shell 11 and the two sliding shells 10 to the concrete slurry to defoam. After a period of defoaming, the operator deactivates the vibration module 13 via the control panel and controls the second electric push rod 12 to reset. The telescopic end of the second electric push rod 12 moves the protective shell 11 and the two sliding shells 10 downwards until the upper surface of the sliding shell 10 is flush with the upper surface of the workbench 1. After that, the concrete slurry is left to stand for a period of time to solidify and set. The demolding process can then be repeated.

[0035] Example 3: Based on Example 2, referring to... Figure 2 , Figure 4 and Figure 5 As shown, it also includes two sets of agitation units, which are set on adjacent sliding shells 10. Each agitation unit includes nine sliding rods 14, which are slidably set on adjacent sliding shells 10. The nine sliding rods 14 are divided into three groups, with three sliding rods 14 in each group distributed circumferentially at equal intervals in the horizontal direction. The sliding rods 14 in the three groups are distributed in a cross pattern. A sliding frame 15 is slidably set inside the sliding shell 10. 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. The sliding frame 15 is provided with nine sets 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 worktable 1 is provided with a control component for controlling the movement of the sliding rods 14 and a drive component for controlling the rotation of all sliding shells 10.

[0036] Reference Figure 4 and Figure 5 As shown, the control component includes a limiting frame 16, which is fixed to the lower surface of the worktable 1. The limiting frame 16 is n-shaped and has a sliding plate 17 that is rotatably connected to the adjacent sliding frame 15. The limiting frame 16 is provided with a protruding ring for restricting 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 a specified position.

[0037] Reference Figure 4 and Figure 5As shown, the drive assembly includes a drive motor 18, which is mounted on the lower surface of the protective shell 11 via a support. The drive motor 18 is electrically connected to the control panel. The output shaft of the drive motor 18 is driven by a gear set to the adjacent sliding shell 10. Both sliding shells 10 are rotatably connected to the protective shell 11. The portions of the two sliding shells 10 located inside the protective shell 11 are fixedly connected to pulleys, and a transmission belt 19 is wound between the two pulleys.

[0038] The working process of this embodiment follows that of embodiment 2, and is described in detail as follows:

[0039] 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 worktable 1, the sliding plate 17 continues to move upward and will contact the convex ring on the adjacent limiting frame 16. Subsequently, the sliding shell 10 continues to move upward. At this time, under the limiting action of the convex ring on the limiting frame 16, the sliding frame 15 and the sliding plate 17 move relative to the adjacent sliding shell 10.

[0040] During the relative movement of the sliding frame 15 and the sliding shell 10, the inclined groove on the sliding frame 15 presses against the adjacent sliding rod 14, and the sliding rod 14 extends out from the adjacent sliding shell 10. After the sliding shell 10 moves to its limit position, the second electric push rod 12 stops working. 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 and stir the concrete slurry in the sliding frame 2, which fully removes the air bubbles in the slurry and further improves the defoaming effect, thereby improving the quality of the pouring.

[0041] After the defoaming operation is performed 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, thus ensuring the quality of the final processed product. Then, the above operation is repeated to perform the demolding operation.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
