Description

Technical Field

[0001] This invention relates to the field of clay brick and tile and building block manufacturing technology, and particularly to a concrete building block manufacturing and molding machine. Background Technology

[0002] Concrete building blocks, as a core product for wall material innovation and green building promotion, are made from cement and aggregates as the main raw materials through batching, mixing, molding and curing. They are widely used in load-bearing walls, infill walls and enclosure structures of industrial and civil buildings, playing an important role in replacing traditional clay bricks, improving construction efficiency and reducing building weight.

[0003] The manufacturing, molding, and curing of concrete building blocks are generally carried out in stages. After the concrete building blocks are manufactured and molded, because the strength of the blocks is very low when they are first demolded, a robotic arm is needed to transfer them smoothly to a support. After the number of demolded blocks reaches a certain level, they are transferred to a curing kiln for steam curing. This process is not only cumbersome and increases the consumption of manpower and resources, but also makes the blocks very easy to break during the multiple transfers, which affects the production quality and yield of concrete building blocks. Summary of the Invention

Several sets of fixed rods are installed on the transmission chain. A U-shaped seat is fixed on each set of fixed rods. A curing frame is fixed on the U-shaped seat. Several carrier plates are inserted into the curing frame. The carrier plates are arranged linearly in the longitudinal direction. Four omnidirectional casters are installed at the bottom of the curing frame. The bottom of the maintenance frame is fixed with a sleeve and a spring A. The sleeve is sleeved on the outside of the spring A. A positioning rod is fixed at the bottom of the spring A. The positioning rod slides with the inner wall of the sleeve. A freely rotatable ball is embedded at the bottom of the positioning rod. The positioning rod slides with the inner wall of the positioning hole.

[0006] Furthermore, two limiting rods are fixed on the positioning rod, and the sleeve is provided with a limiting groove for the sliding of the limiting rods.

[0007] Furthermore, the curing kiln is fixedly connected to an inlet / outlet channel, a steam inlet pipe, and a vacuum pipe. One end of the vacuum pipe is connected to a vacuum pump, and the other end of the steam inlet pipe is connected to a steam generator. Several feet are fixed to the bottom of the curing kiln. A sealing door is hinged to the inlet / outlet channel. The sealing door is equipped with a handle and two latches. The two latches are used to lock the inlet / outlet channel and the sealing door.

[0008] Furthermore, the block forming assembly includes a base plate, on which an extrusion assembly and two robotic arms are mounted, with the two robotic arms positioned at the front and rear sides of the extrusion assembly, respectively.

[0009] Furthermore, the extrusion assembly includes four guide cylinders, all of which are fixedly mounted on the base plate. A spring B is fixed to the top of each guide cylinder, a vibration table is fixed to the top of each of the four springs B, a vibration motor is fixedly mounted to the bottom of the vibration table, a support plate is fixed to the top of the vibration table, and an electromagnet is embedded in the top of the support plate.

[0010] Furthermore, a frame is fixed to the top of the vibration table, and a hydraulic cylinder A and two hydraulic cylinders B are fixedly installed on the top of the frame. A pressure plate is fixedly installed at the output end of the hydraulic cylinder A, and a pressure head is installed at the bottom of the pressure plate. A carrier block is fixedly installed at the output end of the hydraulic cylinder B. A mold is fixed between the two carrier blocks. The mold is located between the pressure plate and the support plate, and the mold is located above the support plate.

[0011] Furthermore, four guide rods are fixed at the bottom of the vibration table, and four springs B are respectively sleeved on the outside of the four guide rods.

[0013] Furthermore, a baffle and a fixing plate are fixed on the U-shaped plate, a hydraulic cylinder C is fixedly installed on the fixing plate, and a scraper is fixedly installed at the output end of the hydraulic cylinder C.

[0014] Furthermore, this device has an external control module for connecting pressure sensors and controlling the operation of all electrical equipment within the device.

[0015] In summary, the technical effects and advantages of this invention are as follows: In this invention, a robotic arm is used to remove the carrier plates one by one from the curing component and send them to the block forming component. The block forming component compresses the mixture into building blocks on the carrier plates, and then the robotic arm sends them back into the curing component. This operation not only reduces the number of transfer steps, but also allows for the alternating use of the two curing components to achieve continuous building block manufacturing and curing. This not only reduces the probability of building blocks being damaged during transportation, but also improves the block manufacturing efficiency and yield.

[0016] In this invention, a robotic arm can be used to remove the cured building blocks one by one from the carrier plate inside the curing component and send them to the location of the conveying component. The hydraulic cylinder C in the conveying component can push the scraper to scrape the cured building blocks off the carrier plate. With the obstruction of the baffle, the building blocks will only fall onto the conveyor belt and be transported to the warehouse for centralized storage. In this way, the manufacturing and curing of building blocks are more mechanized, and the production and processing efficiency of building blocks is significantly improved.

[0017] In this invention, a drive motor A drives a rotating rod B to rotate, which in turn pulls a sprocket to rotate. This causes the sprocket to pull a transmission chain, and several curing frames on the transmission chain can be moved along with them by means of casters, transferring them one by one to the location of the access channel. This facilitates the robotic arm to grab the carrier plate on the curing frame, and the block forming component and conveying component are used to realize the generation and peeling of building blocks on the carrier plate. In this way, the manufacturing and production of building blocks are made more mechanized and intelligent.

[0018] In this invention, when the maintenance frame is indirectly driven to move using the drive motor A, the positioning rod at the bottom of the maintenance frame can be inserted into the positioning hole with the help of the spring force of spring A. This helps the maintenance frame to better align with the inlet and outlet channels, which is beneficial for the robot to accurately transfer the carrier plates on the maintenance frame. After all the carrier plates on the maintenance frame have been transferred, the electric push rod can be used to push the limit block upward, so that the limit block pushes the positioning rod away from the positioning hole, making it convenient for the maintenance frame to move again under the drive of the drive motor A.

[0019] In this invention, a robotic arm is used to place a carrier plate on a pallet. An electromagnet, when energized, magnetically holds the carrier plate in place. Two hydraulic cylinders B push the mold down onto the carrier plate, and then the mixture is fed to the mold. Hydraulic cylinder A pushes the press head down, and a vibration motor drives a vibrating table to vibrate, causing the mixture to be extruded into building blocks on the carrier plate. Afterward, the mold and press head move up to demold the building blocks, allowing the carrier plate to support the building blocks and transfer them to the curing assembly for subsequent steam curing.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Example: Reference Figure 1-12 The concrete building block manufacturing and molding machine shown includes a block molding component, a conveying component, and two curing components. The two curing components are symmetrically placed on both sides of the block molding component. The block molding component is used for extrusion molding of building blocks, the curing components are used for steam curing of the molded blocks, and the conveying component is used for conveying and transferring the cured blocks.

[0025] The curing components include a curing kiln 1, an electric push rod 3, a lifting block 4, a pressure sensor 5, a limit block 6, a rotating rod A7, a rotating rod B8, a drive motor A9, two sprockets 10, a transmission chain 11, multiple feet 23, an inlet / outlet channel 24, a sealing door 25, two latches 26, and a handle 27. A positioning hole 2 is provided at the bottom inner side of the curing kiln 1. The electric push rod 3 is fixedly installed inside the positioning hole 2, and the lifting block 4 is fixedly installed on the output end of the electric push rod 3. Sensor 5 is fixedly installed between lifting block 4 and limiting block 6. Both lifting block 4 and limiting block 6 are located inside positioning hole 2, with limiting block 6 located above lifting block 4. Electric push rod 3 can push lifting block 4 and limiting block 6 to move up and down inside positioning hole 2. The bottom ends of rotating rod A7 and rotating rod B8 are rotatably connected to the inner wall of curing kiln 1 via bearings. Drive motor A9 is fixedly installed inside curing kiln 1 and is used to drive rotating rod B8 to rotate. Two sprockets 10 are respectively sleeved on the outside of rotating rods A7 and B8. A transmission chain 11 is mounted on the two sprockets 10, allowing the drive motor A9 to indirectly drive the transmission chain 11. Multiple feet 23 are fixedly mounted on the bottom of the curing kiln 1 to support it off the ground. An inlet / outlet channel 24 is fixedly mounted on and connected to the curing kiln 1. A sealing door 25 is hinged to the inlet / outlet channel 24. Two latches 26 and a handle 27 are mounted on the sealing door 25. The sealing door 25 can be locked to the inlet / outlet channel 24 by means of two latches 26, so that the sealing door 25 blocks the inlet / outlet channel 24. The use of handle 27 makes it convenient for workers to pull the sealing door 25. The curing kiln 1 is connected to a steam inlet pipe and a vacuum pipe. One end of the vacuum pipe is connected to a vacuum pump, and the other end of the steam inlet pipe is connected to a steam generator. This is used to evacuate the inside of the curing kiln 1 and then send high-pressure steam into the curing kiln 1 to facilitate the steam curing of the building blocks in the curing kiln 1.

[0026] The transmission chain 11 is equipped with multiple sets of fixing rods 13, each set of fixing rods 13 is fixed with a U-shaped seat 12, and a curing frame 14 is fixed on the U-shaped seat 12. Multiple carrier plates 15 are inserted into the curing frame 14. The multiple carrier plates 15 are arranged linearly in the longitudinal direction to support building blocks. The bottom of the curing frame 14 is equipped with a sleeve 17, a spring A18, and four swivel casters 16. The purpose of the four swivel casters 16 is to support the curing frame 14 and assist the curing frame 14 in moving with the transmission chain 11. The sleeve 17 is sleeved on the outside of the spring A18. The bottom end of the spring A18 is fixed with a positioning rod 19. The positioning rod 19 slides with the inner wall of the sleeve 17, and the bottom of the positioning rod 19 is embedded with a freely rotatable part. The ball bearings 20 prevent the bottom of the positioning rod 19 from directly touching the inner wall of the curing kiln 1, facilitating the movement of the positioning rod 19 with the curing frame 14. The positioning rod 19 slides against the inner wall of the positioning hole 2. When the curing frame 14 is indirectly driven to move by the drive motor A9, the positioning rod 19 at the bottom of the curing frame 14 can be inserted into the interior of the positioning hole 2 with the help of the elastic force of the spring A18. This helps the curing frame 14 to better align with the inlet / outlet channel 24, which is beneficial for the accurate transfer of the upper plate 15 on the curing frame 14. Two limiting rods 21 are fixed on the positioning rod 19. The sleeve 17 is provided with a limiting groove 22 for the sliding of the limiting rod 21. The limiting rod 21 cooperates with the limiting groove 22 to prevent the positioning rod 19 from completely detaching from the sleeve 17.

[0027] The block forming component includes a base plate 28, on which an extrusion component and two robotic arms 29 are installed. The two robotic arms 29 are located on the front and rear sides of the extrusion component, respectively. The robotic arms 29 are used to pick up and put down the carrier plate 15 inside the curing kiln 1.

[0028] The extrusion assembly includes four guide cylinders 30, all of which are fixedly mounted on a base plate 28. A spring B31 is fixed to the top of each guide cylinder 30. A vibration table 32 is fixed to the top of each of the four springs B31. A vibration motor 33 is fixedly mounted to the bottom of the vibration table 32. A support plate 34 is fixed to the top of the vibration table 32, and an electromagnet 35 is embedded in the top of the support plate 34. A frame 36 is fixed to the top of the vibration table 32. A hydraulic cylinder A37 and two hydraulic cylinders B38 are fixedly mounted to the top of the frame 36. A pressure plate 39 is fixedly mounted to the output end of hydraulic cylinder A37, and a pressure head 40 is mounted to the bottom of the pressure plate 39. A carrier block 41 is fixedly mounted to the output end of hydraulic cylinder B38. The two carrier blocks 41 are fixedly connected. A mold 42 is positioned between the pressure plate 39 and the support plate 34, with the mold 42 located above the support plate 34. A robotic arm 29 places the carrier plate 15 onto the support plate 34. An electromagnet 35, when energized, magnetically holds the carrier plate 15, helping to fix it onto the support plate 34. Two hydraulic cylinders B38 push the mold 42 down onto the carrier plate 15, and then the mixture is fed to the mold 42. A hydraulic cylinder A37 pushes the pressure head 40 down, and a vibration motor 33 drives the vibration table 32 to vibrate, causing the mixture to be extruded into building blocks on the carrier plate 15. Afterward, the mold 42 and the pressure head 40 move upward to demold the building blocks, allowing the carrier plate 15 to support the building blocks.

[0029] The conveying assembly includes a support base 44, a U-shaped plate 45, two belt rollers 46, a drive motor B47, a conveyor belt 48, a baffle 49, a fixing plate 50, a hydraulic cylinder C51, and a scraper 52. The U-shaped plate 45 is fixedly installed on the top of the support base 44. Both belt rollers 46 are rotatably mounted on the U-shaped plate 45 via bearings. The conveyor belt 48 is sleeved around the two belt rollers 46. One of the belt rollers 46 is driven by the drive motor B47, which in turn drives the conveyor belt 48 to transport building blocks. Both baffle 49 and fixed plate 50 are fixedly installed on U-shaped plate 45. Hydraulic cylinder C51 is fixedly installed on fixed plate 50. Scraper 52 is fixedly installed on the output end of hydraulic cylinder C51. Hydraulic cylinder C51 can push scraper 52 to scrape off the cured building blocks on carrier plate 15. Under the obstruction of baffle 49, the building blocks will only fall onto conveyor belt 48 and be transported to warehouse for centralized storage by conveyor belt 48. This device is connected to an external control module to connect to pressure sensor 5 and control the operation of all electrical equipment in this device.

[0030] Working principle of this invention: S01: Raw material preparation: Mix cement, sand and gravel and fly ash together in proportion to make it into a "dry hard" state, which can be formed into a ball by hand and crumbles when dropped. S02: Forced mixing, which mixes dry materials and water evenly in a forced mixer to ensure that the cement slurry coats every aggregate. S03: Manufacturing and forming. First, the control module controls the drive motor A9 to be powered on, causing the drive motor A9 to drive the rotating rod B8 to rotate. The rotating rod B8 pulls the sprocket 10 to rotate, causing the sprocket 10 to pull the transmission chain 11 to drive. The transmission chain 11 pulls multiple curing frames 14 inside the curing kiln 1 to move until the positioning rod 19 at the bottom of the curing frame 14 is inserted into the positioning hole 2. The ball bearing 20 at the bottom of the positioning rod 19 abuts against the limit block 6, squeezing the limit block 6. The limit block 6 squeezes the pressure sensor 5, causing the pressure sensor 5 to transmit a signal to the control module. The control module then controls the drive motor A9 to stop running according to the command. The control module also controls the front robot arm 29 to run according to the command, causing the robot arm... 29. Carrier plates 15 are taken out one by one from the curing frame 14 corresponding to the inlet / outlet channel 24. The removed carrier plates 15 are placed on the pallet 34 by the robot arm 29. The control module first controls the electromagnet 35 to be energized and magnetically attract the carrier plate 15 according to the instruction. Then, it controls the two hydraulic cylinders B38 to extend, so that the two hydraulic cylinders B38 push the mold 42 to be in close contact with the carrier plate 15. Subsequently, the mixture is sent to the mold 42. The control module controls the hydraulic cylinder A37 to extend and controls the vibration motor 33 to be energized and run according to the instruction. The vibration table 32 vibrates at high frequency to expel the air in the mixture and make the particles closely arranged. The press head 40 presses down synchronously to apply huge pressure and extrudes the mixture in the mold 42 to form the initial manufacturing of building blocks. S04: Block demolding. The control module controls the vibration motor 33 to cut off the power according to the instruction, and controls the two hydraulic cylinders B38 to first retract a distance slightly higher than the block thickness, and then controls the hydraulic cylinder A37 to pull the pressure head 40 upward until the pressure head 40 and the mold 42 return to the starting height. The demolded building block stays on the carrier plate 15. S05: Block stacking. The control module controls the robot arm 29 according to the instructions to send the carrier plate 15 and the building blocks on it back to the curing frame 14. Then, the carrier plate 15 below it is extracted. Part of the operation of step S03 and all of the operation of S04 are repeated until all the carrier plates 15 on the curing frame 14 are carrying building blocks. Then, the control module controls the electric push rod 3 according to the instructions to push the limit block 6 upward. After pushing the positioning rod 19 away from the positioning hole 2, the drive motor A9 is controlled again to drive the transmission chain 11 to drive. All the operations of steps S03-S04 are repeated until all the carrier plates 15 in the curing kiln 1 are carrying building blocks. S06: Steam curing. Close the sealing door 25 on the curing kiln 1 filled with blocks and lock it with the latch 26. First, use the control module to control the operation of the external vacuum pump, so that the vacuum pump evacuates the inside of the curing kiln 1. After evacuating for 30-50 minutes, introduce high-pressure steam into the inside of the curing kiln 1 at a rate of less than 20-30℃ / h, raise it to 150-200℃ and 1.0-1.6MPa, and keep it at a constant temperature for 4-8 hours to complete the hydrothermal synthesis and achieve the required block strength. Slowly exhaust the steam to reduce the pressure and allow it to cool naturally at a rate of less than 20-30℃ / h. After it drops to atmospheric pressure and close to room temperature, the blocks are discharged from the kiln. While one curing kiln 1 is steam curing the blocks, the other curing kiln 1 can continue to be used for loading building blocks, so that the production of building blocks can be carried out without stopping the machine. S07: Block transfer. Open the sealed door 25 on the curing kiln 1 where the blocks have been cured. The control module controls the rear robotic arm 29 to remove the cured building blocks from the curing kiln 1 according to the instructions. The robotic arm 29 transfers the carrier plate 15 carrying the cured building blocks to the top of the conveyor belt 48. The control module controls the hydraulic cylinder C51 to push the scraper 52 to push the building blocks on the carrier plate 15 onto the conveyor belt 48. The building blocks are then transported to the warehouse for stacking and storage via the conveyor belt 48.
