Abstract
Description
Technical Field
[0001] This utility model relates to the field of aerated concrete technology, and in particular to a brick pressing device for the production of autoclaved aerated concrete blocks. Background Technology
[0002] The brick pressing device for autoclaved aerated concrete (AAC) block production is a piece of equipment used to compress AAC raw materials into blocks. It is primarily used for producing AAC blocks and consists of a brick press, conveyor belt, and molding molds. Its working principle involves using a hydraulic system to provide strong pressure, pressing the mixed AAC slurry into blocks of a specific size. The brick press uses hydraulic cylinders to push the molds, ensuring the slurry is evenly compacted within the molds, guaranteeing accurate block dimensions and uniform density. This device features high efficiency and stable performance, and the pressing pressure and molding speed can be adjusted according to production needs to adapt to the production requirements of blocks of different specifications.
[0003] Patent CN209453784U discloses a brick pressing device for the production of autoclaved aerated concrete blocks. Specifically, the patent discloses a technical solution comprising: "a working platform, a first pressure plate on the working platform, a second pressure plate on the first pressure plate, a mold on the second pressure plate, a mold cavity inside the mold, a through hole communicating with the mold cavity between the first and second pressure plates, a cylinder inside the working platform, a telescopic rod on the cylinder, the telescopic rod passing through the through holes of the first and second pressure plates and extending into the mold cavity, and a pad inside the mold cavity." This solution achieves the technical effects of "long service life, convenient maintenance, and high stability."
[0004] During long-term use, existing equipment may accumulate clay residue, dust, or other debris in the mold cavity and on the surface of the pressure plate due to the pressing operation. Since the pressure plate and the mold cavity are in frequent contact, cleaning these residues may require disassembling some components, making the cleaning process cumbersome. At the same time, the clay in the mold cavity may be subjected to uneven pressure during hydraulic cylinder pressing, especially when the shape of the mold cavity and the force distribution are uneven, resulting in differences in the size and density of the formed bricks, which affects the quality of the bricks.
[0005] Therefore, we propose a brick pressing device for the production of autoclaved aerated concrete blocks. Utility Model Content

[0028] Example
[0029] like Figure 1-4As shown, this utility model provides a technical solution: a brick pressing device for producing autoclaved aerated concrete blocks, including a workbench 1 for bearing the weight of other components and providing a stable operating surface. A support frame 2 is fixedly installed on the top of the workbench 1 to support and stabilize the transmission component, the first threaded rod 3, and other components. A transmission component is provided on the top of the support frame 2, and a first threaded rod 3 is provided on the top of the support frame 2, which can convert the rotational motion of the transmission component into a lifting linear motion. The transmission component drives the first threaded rod 3 to perform lifting motion. The first threaded rod 3 passes through the support frame 2 and is slidably connected to it. A fixing plate 4 is fixedly installed at the bottom of the first threaded rod 3 to ensure the accurate positioning of the pressure sensor 5 and to provide a stable support platform so that the pressure sensor 5 can sense the pressure applied to the upper pressure plate 6. Multiple pressure sensors 5 are fixedly installed at the end of the fixing plate 4 away from the first threaded rod 3 to detect the magnitude of the pressure applied by the upper pressure plate 6. The upper pressure plate 6 is fixedly installed at the bottom of the pressure sensor 5, and the pressing of the object is completed by applying pressure.
[0030] A connecting rod 7 is fixedly installed on one side of the support frame 2, which serves to connect and transmit power. The connecting rod 7 is equipped with a cleaning component to clean the dust residue on the surface of the workbench 1. The transmission component drives the cleaning component to rotate and clean.
[0031] The transmission assembly includes a rotating shaft 8, a first pulley 9, a second pulley 10, and a first belt 11. A first motor 12 is fixedly mounted on the top of the support frame 2. A coaxial fixed connection with the rotating shaft 8 ensures that power can be effectively transmitted from the first motor 12 to the rotating shaft 8. The output end of the first motor 12 is coaxially fixedly connected to the rotating shaft 8, transmitting power to the first pulley 9 through this connection. The first pulley 9 is coaxially fixedly connected to the outer circumference of the rotating shaft 8. The rotation of the rotating shaft 8 drives the first pulley 9 to rotate, thereby driving the first belt 11. A support base 13 is fixedly mounted on the top of the support frame 2 to fix the second pulley 10 and provide stable support. A second belt 11 is provided on the top of the support base 13. The pulley 10 receives power from the first pulley 9 and transmits it to the second belt 15 and the connecting rod 7. The first belt 11 is sleeved on the outer periphery of the first pulley 9 and the second pulley 10. The transmission assembly also includes a third pulley 14 and a second belt 15. The third pulley 14 is located on the top of the connecting rod 7. The third pulley 14 transmits power from the first pulley 9 to the connecting rod 7 through the second belt 15. The second belt 15 is sleeved on the outer periphery of the first pulley 9 and the third pulley 14. The top of the second pulley 10 is coaxially fixedly connected to a first threaded block 16, which transmits force through the thread to assist in adjusting the position of the first threaded rod 3. The first threaded block 16 is internally threadedly connected to the first threaded rod 3.
[0032] The cleaning assembly includes a telescopic rod 17, a dust collection box 18, a suction hose 19, and a filter 20. The telescopic rod 17 provides support for rotational movement and is rotatably connected to the inside of a connecting rod 7 via a bearing. A third pulley 14 is coaxially fixedly connected to the top of the connecting rod 7. The dust collection box 18 is fixedly installed at the end of the telescopic rod 17 away from the third pulley 14. A vacuum cleaner is installed inside the dust collection box 18, and the suction hose 19 is fixedly connected to the bottom of the dust collection box 18. The suction hose 19 guides dust and impurities into the dust collection box 18 through suction force. The suction hose 19 is close to the top of the workbench 1 to ensure that dust on the surface of the workbench 1 can be effectively sucked in during cleaning operations. A filter 20 is slidably connected inside the dust collection box 18 to ensure that the sucked-in air can be filtered during the vacuuming process to prevent dust and impurities from flowing back into the working environment. A fixed base 21 is fixedly installed inside the workbench 1. The workbench 1 provides a stable support platform for the components inside. The top of the fixed base 21 is provided with a second threaded block 22, and the top of the second threaded block 22 is coaxially fixedly connected with a worm gear 23. The workbench 1 is fixedly installed with a second motor 24. The output end of the second motor 24 is coaxially fixedly connected with a worm gear 25 through a coupling. The worm gear 23 meshes with the tooth surface of the worm gear 25, and the rotation can be converted into precise linear motion to drive the second threaded rod 26. The second threaded block 22 is internally threaded with the second threaded rod 26, allowing the second threaded rod 26 to move up and down, thereby realizing the vertical adjustment of the lower pressure plate 27. The top of the second threaded rod 26 is fixedly installed with the lower pressure plate 27. The lower pressure plate 27 cooperates with the upper pressure plate 6. After pressing, the pressed brick can be pushed out of the pressing groove opened in the workbench 1, making it easier to remove the pressed brick.
[0033] The working process of this utility model:
[0034] Step 1: When the equipment is started, the first motor 12 drives the first pulley 9 through the rotating shaft 8, and then transmits power to the second pulley 10 through the first belt 11. At the same time, the power is transmitted to the third pulley 14 and the connecting rod 7. During the brick pressing process, the group vacuuming is carried out. Through this transmission system, the telescopic rod 17 of the cleaning component starts to rotate, the vacuum cleaner starts to work, and the vacuum pipe 19 starts to suck up the dust and impurities on the surface of the workbench 1. At the same time, the transmission component also drives the rotation of the first threaded rod 3, thereby driving the adjustment of the upper pressure plate 6 and the lower pressure plate 27.
[0035] Step two: Driven by the transmission system, the first threaded rod 3 and the second threaded rod 26 begin to move up and down. The pressure sensor 5 fixed on the first threaded rod 3 can sense the pressure on the upper pressure plate 6 and transmit the information. At this time, the pressure sensor 5 adjusts according to the pressure on the upper pressure plate 6 to ensure that the mud is pressed evenly. The lower pressure plate 27 is adjusted by the lifting and lowering of the second threaded rod 26 to make it precisely match the upper pressure plate 6, thereby achieving a uniform pressing effect.
[0036] Step 3: After pressing is completed, the device will automatically raise the lower pressure plate 27 through a precisely controlled lifting system. At this time, the pressed bricks will be pushed out of the mold cavity and raised from the pressing groove opened in the worktable 1, so that the bricks can be easily removed, avoiding the tediousness and possible damage caused by manual disassembly. In addition, the automatic cleaning system effectively prevents the accumulation of dust and impurities during the cleaning process, ensuring the continuous stability of the operation process.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
