Description

Technical Field

[0001] This invention relates to the field of concrete block processing technology, specifically to a concrete block turning device and a block manufacturing process. Background Technology

[0002] After the mortar of aerated concrete blocks hardens to a certain extent in the mold, the blocks are demolded and cut. To ensure the integrity of the aerated concrete blocks, a bottom layer is left after cutting. This bottom layer does not meet the size requirements of the blocks, so the bottom layer needs to be removed after cutting. Currently, the bottom layer removal is mainly done by turning the blocks over using a turning machine: one side of the block is supported by a turning plate on the turning machine, then it is turned 90°, and then the bottom layer is pressed off by a pressure plate. Finally, the block is turned back to its original position, thus completing the bottom layer removal process.

[0003] To address the aforementioned issues, Chinese invention patent application number 202320306228.8 discloses a concrete block flipping device. This device rotates a second rotating shaft via a push rod, enabling the rotating plate to rise and fall. This allows adjustment of the distance between the bottom of the rotating plate and the top of the operating table, which in turn allows the bottom layer of the concrete block blank to be exposed from the bottom of the rotating plate, facilitating the scraping of the bottom of the concrete block blank.

[0004] However, in actual use, the device is inconvenient for removing hardened concrete from the mold, which reduces its practicality and fails to meet the usage requirements. Summary of the Invention

[0005] The purpose of this invention is to provide a concrete block flipping device and a block manufacturing process to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A concrete block turning device includes: a base, a mold frame assembly, the mold frame assembly including a mold frame body with an open top and front side, a limiting baffle installed on the front side of the mold frame body, and a sealing plate inserted between the mold frame body and the limiting baffle to close the front side of the mold frame body; a first conveying mechanism, installed on the base, for conveying the mold frame assembly filled with concrete; a second conveying mechanism, installed on the base, for conveying the sealing plate with concrete supported at the top; a moving mechanism, installed on the base, for driving the clamping and turning mechanism to move; and a clamping and turning mechanism, installed on the moving mechanism, for turning the mold frame assembly 90° and cooperating with the moving mechanism to transfer the mold frame body to the second conveying mechanism.

[0008] As a preferred embodiment, both conveying mechanism one and conveying mechanism two are composed of the same conveying components. Each conveying component includes multiple sets of conveying frames mounted on a base. Each conveying frame has a conveying roller rotatably mounted inside it. A conveying motor is mounted on the conveying frame, and the output end of the conveying motor is drivenly connected to the shaft end of the conveying roller.

[0009] As a preferred embodiment, each of the conveying rollers is also equipped with conveying limit rings on both sides.

[0010] As a preferred embodiment, the moving mechanism includes a moving frame mounted on a base, a moving screw rotatably mounted on the moving frame, a moving slide threaded onto the moving screw, a moving motor mounted at the end of the moving frame, the output end of the moving motor being drivenly connected to the shaft end of the moving screw, and a lifting electric push rod mounted on the upper end of the moving slide, the telescopic end of the lifting electric push rod passing through the moving slide and fixed with a lifting seat plate.

[0011] As a preferred embodiment, the movable slide is slidably mounted on the movable frame.

[0012] As a preferred embodiment, the clamping and flipping mechanism includes a clamping screw rotatably mounted on the lower end of the lifting seat plate, a pair of clamping plates slidably mounted on the lower end of the lifting seat plate, the clamping plates being threaded onto the clamping screw, a clamping motor being mounted on the lifting seat plate, the output end of the clamping motor being drivenly connected to the shaft end of the clamping screw, a rotating seat being rotatably mounted on the opposite side of the clamping plates, a flipping motor being mounted on the clamping plates, the output end of the flipping motor being drivenly connected to the shaft end of the rotating seat;

[0013] A clamping block is also installed on the opposite side of the rotating seat, and clamping slots are opened at corresponding positions on the left and right sides of the mold frame body.

[0014] As a preferred embodiment, the threads at both ends of the clamping screw are in opposite directions.

[0015] A process for manufacturing concrete blocks includes the following steps:

[0016] S1. Insert the sealing plate between the limiting baffle and the mold frame to complete the assembly of the mold frame assembly;

[0017] S2. Inject the prepared concrete slurry into the mold frame assembly, defoam it, and then allow the concrete slurry to harden initially.

[0018] S3. The mold frame assembly is transferred to the top of the conveying mechanism by the overhead crane. Then, the conveying motor is started, and the conveying roller is rotated by the conveying motor to convey the mold frame assembly to the right. When the mold frame assembly moves to the position directly below the moving mechanism, the conveying is stopped.

[0019] S4. The lifting electric push rod extends, pushing the lifting seat plate down, thereby causing the clamping and flipping mechanism to move down, so that the mold frame assembly is located between the clamping plates on both sides. Then the clamping motor is started, which drives the clamping screw to rotate, thereby bringing the clamping plates on both sides closer to each other, and causing the clamping blocks on the rotating seat to be inserted into the clamping slots on both sides of the mold frame body, thus completing the fixing of the mold frame assembly.

[0020] S5. The lifting electric push rod is reset, which drives the lifting seat plate to move up, thereby driving the mold frame assembly to move up. Then the flipping motor is started, which drives the rotating seat to rotate 90°, thereby driving the mold frame assembly to flip 90°.

[0021] S6. The lifting electric push rod extends, pushing the lifting seat plate down, thereby moving the mold frame assembly down. When the sealing plate of the mold frame assembly moves onto the conveying roller, the downward movement stops, and at this time the concrete inside the mold frame assembly presses onto the sealing plate.

[0022] S7. Start the moving motor, which drives the moving screw to rotate, thereby moving the moving slide backward. At this time, the clamping and flipping mechanism drives the mold frame body to move backward. The conveying limit ring on the conveying roller limits the sealing plate to prevent it from moving, thereby separating the mold frame body from the sealing plate and taking the concrete out of the mold frame assembly. Stop moving when the mold frame body moves directly above the second conveying mechanism.

[0023] S8. The lifting electric push rod resets, causing the lifting seat plate to move upward, thereby causing the mold frame body to move upward. Then, the flipping motor is started, which drives the rotating seat to rotate 90° in the opposite direction. Then, the lifting electric push rod resets, pushing the lifting seat plate downward, causing the mold frame body to move downward. After the mold frame body contacts the conveying roller of the second conveying mechanism, the movement stops. Then, the clamping flipping mechanism releases the mold frame body. Immediately afterwards, the lifting electric push rod resets, and then the moving motor drives the moving screw to rotate in the opposite direction, causing the moving slide to reset. The mold frame body is then transferred away through the second conveying mechanism.

[0024] S9. The sealing plate and concrete are transferred to the cutting station by the conveying mechanism. The concrete is cut by the external cutting device, and then the cut concrete blocks are transported to the autoclave for steam curing.

[0025] Compared with existing technologies, the advantages of this invention are as follows: A movable motor drives a movable lead screw to rotate, thereby moving the movable slide backward. At this time, the clamping and flipping mechanism moves the mold frame body backward, and the conveying limit ring on the conveying roller limits the sealing plate, preventing its movement. This achieves separation between the mold frame body and the sealing plate, allowing the concrete to be removed from the mold frame assembly. This invention has a reasonable structure, can automatically remove hardened concrete from the mold frame assembly, effectively reduces processing time, and better meets usage requirements.

Detailed Implementation

[0031] 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.

[0032] Example: Please refer to Figures 1-4 A concrete block flipping device includes: a base 1, a mold frame assembly, the mold frame assembly including a mold frame body 3 with an open top and front side, a limiting baffle 31 installed on the front side of the mold frame body 3, and a sealing plate 32 for closing the front side of the mold frame body 3 inserted between the mold frame body 3 and the limiting baffle 31; a first conveying mechanism 2, installed on the base 1, for conveying the mold frame assembly with poured concrete; a second conveying mechanism 6, installed on the base 1, for conveying the sealing plate 32 with concrete supported at the top; a moving mechanism 4, installed on the base 1, for driving a clamping and flipping mechanism 5 to move; the clamping and flipping mechanism 5, installed on the moving mechanism 4, for flipping the mold frame assembly 90° and cooperating with the moving mechanism 4 to transfer the mold frame body 3 to the second conveying mechanism 6.

[0033] As a further embodiment, both conveying mechanism 1 2 and conveying mechanism 2 6 are composed of the same conveying components. The conveying components include multiple sets of conveying frames 21 mounted on the base 1. Each conveying frame 21 has a conveying roller 22 rotatably mounted inside it. A conveying motor 23 is mounted on the conveying frame 21. The output end of the conveying motor 23 is drivenly connected to the shaft end of the conveying roller 22. In this embodiment, conveying limiting rings 24 are also installed on both sides of each conveying roller 22.

[0034] The working principle of the conveying assembly is as follows: When conveying, the conveying motor 23 is started, and the conveying roller 22 is rotated by the conveying motor 23 to carry out the conveying work.

[0035] As a further embodiment, the moving mechanism 4 includes a moving frame 41 mounted on a base 1, a moving screw 42 rotatably mounted on the moving frame 41, a moving slide 44 threaded onto the moving screw 42, a moving motor 43 mounted at the end of the moving frame 41, the output end of the moving motor 43 being drivenly connected to the shaft end of the moving screw 42, a lifting electric push rod 45 mounted on the upper end of the moving slide 44, the telescopic end of the lifting electric push rod 45 passing through the moving slide 44 and fixed with a lifting seat plate 46, and the moving slide 44 being slidably mounted on the moving frame 41.

[0036] The working principle of the moving mechanism 4 is as follows: When it is necessary to adjust the position of the clamping and flipping mechanism 5, the moving motor 43 is started. The moving motor 43 drives the moving screw 42 to rotate, which in turn drives the moving slide 44 to move backward, thereby driving the clamping and flipping mechanism 5 to move backward. When it is necessary to reset the clamping and flipping mechanism 5, the moving motor 43 drives the moving screw 42 to rotate in the opposite direction, which causes the moving slide 44 to move forward, thereby realizing the reset of the clamping and flipping mechanism 5.

[0037] As a further embodiment, the clamping and flipping mechanism 5 includes a clamping screw 52 rotatably mounted on the lower end of the lifting seat plate 46. A pair of clamping plates 53 are also slidably mounted on the lower end of the lifting seat plate 46. The clamping plates 53 are threaded onto the clamping screw 52. A clamping motor 51 is also mounted on the lifting seat plate 46. The output end of the clamping motor 51 is drivenly connected to the shaft end of the clamping screw 52. A rotating seat 54 is rotatably mounted on the opposite side of the clamping plates 53. A flipping motor 55 is also mounted on the clamping plates 53. The output end of the flipping motor 55 is drivenly connected to the shaft end of the rotating seat 54. A clamping insert 541 is also mounted on the opposite side of the rotating seat 54. Clamping slots 542 are provided at corresponding positions on the left and right sides of the mold frame body 3. The threads at both ends of the clamping screw 52 are in opposite directions.

[0038] The working principle of the clamping and flipping mechanism 5 is as follows: When it is necessary to fix the mold frame assembly, the clamping motor 51 is started, and the clamping screw 52 is driven to rotate in the forward direction by the clamping motor 51, so that the clamping plates 53 on both sides are brought closer to each other. When the clamping blocks 541 on the rotating seat 54 are inserted into the clamping slots 542 at the corresponding positions on both sides of the mold frame body 3, the fixing work can be completed. When it is necessary to release the mold frame body 3, the clamping motor 51 drives the clamping screw 52 to rotate in the reverse direction, so that the clamping plates 53 on both sides are moved away from each other, and the mold frame body 3 can be released.

[0039] By rotating the rotating seat 54 with the rotating motor 55, the mold frame assembly clamped between the rotating seats 54 can be flipped.

[0040] A process for manufacturing concrete blocks includes the following steps:

[0041] S1. Insert the sealing plate between the limiting baffle and the mold frame to complete the assembly of the mold frame assembly;

[0042] S2. Inject the prepared concrete slurry into the mold frame assembly, defoam it, and then allow the concrete slurry to harden initially.

[0043] S3. The mold frame assembly is transferred to the top of the conveying mechanism by the overhead crane. Then, the conveying motor is started, and the conveying roller is rotated by the conveying motor to convey the mold frame assembly to the right. When the mold frame assembly moves to the position directly below the moving mechanism, the conveying is stopped.

[0044] S4. The lifting electric push rod extends, pushing the lifting seat plate down, thereby causing the clamping and flipping mechanism to move down, so that the mold frame assembly is located between the clamping plates on both sides. Then the clamping motor is started, which drives the clamping screw to rotate, thereby bringing the clamping plates on both sides closer to each other, and causing the clamping blocks on the rotating seat to be inserted into the clamping slots on both sides of the mold frame body, thus completing the fixing of the mold frame assembly.

[0045] S5. The lifting electric push rod is reset, which drives the lifting seat plate to move up, thereby driving the mold frame assembly to move up. Then the flipping motor is started, which drives the rotating seat to rotate 90°, thereby driving the mold frame assembly to flip 90°.

[0046] S6. The lifting electric push rod extends, pushing the lifting seat plate down, thereby moving the mold frame assembly down. When the sealing plate of the mold frame assembly moves onto the conveying roller, the downward movement stops, and at this time the concrete inside the mold frame assembly presses onto the sealing plate.

[0047] S7. Start the moving motor, which drives the moving screw to rotate, thereby moving the moving slide backward. At this time, the clamping and flipping mechanism drives the mold frame body to move backward. The conveying limit ring on the conveying roller limits the sealing plate to prevent it from moving, thereby separating the mold frame body from the sealing plate and taking the concrete out of the mold frame assembly. Stop moving when the mold frame body moves directly above the second conveying mechanism.

[0048] S8. The lifting electric push rod resets, causing the lifting seat plate to move upward, thereby causing the mold frame body to move upward. Then, the flipping motor is started, which drives the rotating seat to rotate 90° in the opposite direction. Then, the lifting electric push rod resets, pushing the lifting seat plate downward, causing the mold frame body to move downward. After the mold frame body contacts the conveying roller of the second conveying mechanism, the movement stops. Then, the clamping flipping mechanism releases the mold frame body. Immediately afterwards, the lifting electric push rod resets, and then the moving motor drives the moving screw to rotate in the opposite direction, causing the moving slide to reset. The mold frame body is then transferred away through the second conveying mechanism.

[0049] S9. The sealing plate and concrete are transferred to the cutting station by the conveying mechanism. The concrete is cut by the external cutting device, and then the cut concrete blocks are transported to the autoclave for steam curing.
