Abstract
Description
Technical Field
[0001] This invention relates to the field of building block technology, and in particular to a closed-loop system for reducing block height error. Background Technology
[0002] A block molding machine is a machine that uses fly ash, river sand, gravel, stone powder, fly ash, waste ceramsite slag, smelting slag, and other materials, with a small amount of cement added, to produce new wall material blocks. These new wall materials are mainly blocks and cement bricks. Most use hydraulic molding, but some use vibration molding. The block molding machine operates in a quiet, static pressure mode. It is noiseless, has high output, and high density. No pallet curing is required, and the curing cycle is short. It requires few personnel, has no requirements for the working surface, and produces a wide variety of products.
[0003] Even within the same mold cavity, blocks produced by existing block forming machines often exhibit some degree of height variation, a common issue in the industry. If this variation exceeds the standard value and is not adjusted promptly, continued production can render subsequently produced blocks unusable, leading to waste and reduced production efficiency. Summary of the Invention
[0004] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.
[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a closed-loop system for reducing block height errors. This application utilizes a block height detection mechanism for high-speed, high-precision measurement of block height. First, the measured block height is subtracted from the standard block height set in the control system to obtain a positive or negative error value. Then, the positive or negative error value is compared with the allowable error range set in the control system. When the error value is outside the allowable range, the anti-arching mechanism on the material cart assembly is adjusted in a timely manner to regulate the feeding amount, thereby indirectly controlling and reducing the block height error. This greatly ensures the uniformity of block height produced by the block forming machine and improves the strength of the entire batch of bricks.
[0006] To achieve the above objectives, the technical solution of the present invention is:
[0007] A closed-loop system for reducing block height error includes: a feeding mechanism, a storage device, a block forming machine body, a material cart assembly, a block height detection mechanism, a brick feeder, and a control system. The storage device is located above the feeding mechanism. The material cart assembly is located at the bottom of the block forming machine body. The block height detection mechanism is located on the brick feeder. The control system processes the block height feedback from the block height detection mechanism and adjusts the feeding of the material cart assembly. The brick feeder transports the blocks manufactured by the block forming machine. The structural design of the brick feeder can be flexibly configured according to usage requirements. It can be configured as a brick feeder with a rotating platform, allowing the manufactured blocks to adjust their direction to match the corresponding transport line direction. Furthermore, the transport line can be configured as a transport line with a lifting structure.
[0008] This application mainly utilizes a block height detection mechanism to collect block height information and then feeds it back to the control system for analysis and processing. After processing, the system feeds back to control the corresponding mechanical components to perform corresponding actions. The entire information processing and feedback constitutes a complete closed loop.
[0009] In some implementations, the material cart assembly is equipped with an arch-breaking mechanism.
[0010] In some embodiments, the arch-breaking mechanism includes an arch-breaking rod and a phase adjustment device, with the phase adjustment device connected to both ends of the arch-breaking rod.
[0011] In some embodiments, the phase adjustment device includes a moving wheel, a fixed wheel, a first air inlet, a frame plate, a connecting rod, a positioning plate, and a second air inlet. The moving wheel is provided with the first and second air inlets, and the moving wheel is in contact with the fixed wheel, forming a wheel set. The phase adjustment device is provided with three wheel sets, and the wheel sets are connected by the connecting rod. The wheel sets are mounted on the positioning plate, and the positioning plate is installed in conjunction with the frame plate. Through pneumatic transmission, one of the two air inlets is used for air intake, and the other for air exhaust. By changing the air pressure difference in the left and right air chambers of the phase adjustment device, the moving wheel rotates counterclockwise or clockwise. At this time, the arch-breaking rod shifts backward or forward, thereby increasing or decreasing the feeding amount of each row of mold cavities, making the material distribution more uniform, and thus reducing the height error of the blocks. With a larger feeding amount and a fixed mold cavity, the height of the blocks after compression by the block forming machine will increase. Conversely, it will decrease.
[0012] In some implementations, a laser displacement sensor is installed on the block height detection mechanism.
[0013] In some implementations, the control system is also used to control the electrical components on the material feeding mechanism, the material storage device, the block forming machine body, the block height detection mechanism, and the brick feeder. The control system is electrically connected to the control of the material feeding mechanism, the material storage device, the block forming machine body, the material cart assembly, the block height detection mechanism, and the brick feeder.
[0014] In some implementations, the control system is wirelessly connected to the material feeding mechanism, the material storage device, the block forming machine body, the material cart assembly, the block height detection mechanism, and the brick feeder.
[0015] In some implementations, at least one block height detection mechanism is provided. When the conveyor line is long, providing multiple block height detection mechanisms can significantly reduce measurement errors.
[0016] In some embodiments, the phase adjustment device further includes an air pipe that is connected to a first air inlet and a second air inlet, respectively. The air pipe is connected to an air pump, and the air pump is electrically connected to the control system.
[0017] By adopting the above technical solution, the beneficial effects of the present invention are:
[0018] This application uses a block height detection mechanism to monitor the height of blocks produced by a block forming machine. The monitoring data is then fed back to the control system for analysis and processing. The results are then fed back to the corresponding phase adjustment device on the material cart assembly for real-time adjustment. The phase adjustment device controls the amount of bricks on one side of the block mold cavity by adjusting the anti-arch rod, thereby regulating the block height. The block height detection mechanism continuously collects the height of blocks produced by the block forming machine from the same plate, continuously analyzes and processes the data through the control system, and repeats this process to achieve closed-loop real-time control monitoring and adjustment. This closed-loop system effectively ensures real-time adjustment of block height errors by the block forming machine, guaranteeing the uniformity of the produced blocks.

[0048] According to some embodiments of this application, a closed-loop system for reducing block height error is provided, including a feeding mechanism 1, a storage device 2, a block forming machine body 3, a material cart assembly 4, a block height detection mechanism 5, a brick feeder 6, and a control system 8. The storage device 2 is located above the feeding mechanism 1. The material cart assembly 4 is located at the bottom of the block forming machine body 3. The block height detection mechanism 5 is located on the brick feeder 6.

[0051] According to some embodiments of this application, optionally, the material cart assembly 4 is provided with an arch-breaking mechanism 41.
[0052] According to some embodiments of this application, optionally, the arch-breaking mechanism 41 includes an arch-breaking rod 411 and a phase adjustment device 412, with the phase adjustment device 412 connected to both ends of the arch-breaking rod 411.
[0053] Reference Figure 3 , Figure 7 , Figure 8 , Figure 3 For this application Figure 2 A magnified view of a portion of point A in the middle; Figure 7 This is an exploded structural diagram of a phase adjustment device 412 in a closed-loop system for reducing block height error according to some embodiments of this application. Figure 8 This is a schematic diagram of the structure of a fixed wheel and a moving wheel in a closed-loop system for reducing block height error according to some embodiments of this application.
[0054] According to some embodiments of this application, optionally, the phase adjustment device 412 includes a moving wheel 4121, a fixed wheel 4122, a first air inlet 4123, a frame plate 4124, a connecting rod 4125, a positioning plate 4126, and a second air inlet 4127. The moving wheel 4121 is provided with the first air inlet 4123 and the second air inlet 4127. The moving wheel 4121 and the fixed wheel 4122 are in contact with each other. The moving wheel 4121 and the fixed wheel 4122 constitute a wheel set. The phase adjustment device 412 is provided with three wheel sets, and the wheel sets are connected by the connecting rod 4125. The wheel sets are installed on the positioning plate 4126, and the positioning plate 4126 is installed in cooperation with the frame plate 4124. Through pneumatic transmission, two air inlets, one for intake and one for exhaust, change the air pressure difference in the left and right air chambers of the phase adjustment device 412, causing the driving wheel 4121 to rotate counterclockwise or clockwise. This causes the arch-breaking rod 411 to shift backward or forward, increasing or decreasing the feeding amount in each mold cavity, resulting in more uniform material distribution and reducing block height error. A higher feeding amount, with a fixed mold cavity, will increase the height of the block after compression by the block forming machine. Conversely, a lower feeding amount will decrease the height. The phase adjustment device 412 also includes an air pipe, which is connected to the first air inlet 4123 and the second air inlet 4127, respectively. The air pipe is connected to an air pump, which is electrically connected to the control system. The control system 8 processes the block height feedback from the block height detection mechanism 5 and adjusts the feeding of the material cart assembly 4. Furthermore, after analyzing and processing the block height feedback from the block height detection mechanism 5, the subsequent action is to control the phase adjustment device 412, that is, to control the air pump direction connected to the control system 8. Through the pneumatic transmission wheel 4121, the arch-breaking rod 411 is connected and set on the wheel 4121, so as to realize the adjustment of the arch-breaking rod 411 in different directions.
[0055] According to some embodiments of this application, optionally, a laser displacement sensor is provided on the block height detection mechanism 5. That is, the block height detection mechanism 5 measures, calculates and collects the height data of the block by means of a laser displacement sensor. It can be, but is not limited to, a laser displacement sensor, or other electrical components that can measure and calculate the block height.
[0056] According to some embodiments of this application, optionally, the control system 8 is also used to control the electrical components on the material feeding mechanism 1, the material storage device 2, the block forming machine body 3, the block height detection mechanism 5, and the brick feeder 6. The control system 8 is electrically connected to control the material feeding mechanism 1, the material storage device 2, the block forming machine body 3, the material cart assembly 4, the block height detection mechanism 5, and the brick feeder 6, respectively. The control system 8 not only controls the corresponding mechanical and electrical components of the block forming machine, but also plays a role in analyzing and providing feedback on the block height detection mechanism 5.
[0057] According to some embodiments of this application, optionally, the control system 8 is wirelessly connected to the control material feeding mechanism 1, the material storage device 2, the block forming machine body 3, the material cart assembly 4, the block height detection mechanism 5, and the brick feeder 6.
[0058] According to some embodiments of this application, optionally, at least one block height detection mechanism 5 is provided. In cases where the conveyor line is long, providing multiple block height detection mechanisms 5 can effectively reduce measurement errors.
[0059] Blocks are fed from the block forming machine by the brick feeding machine 6, and their height is measured by the block height detection mechanism 5. The measured data is uploaded to the control system 8 (the program and algorithm are pre-set). The control system 8 compares the measured data with the pre-set block height error range, analyzes it, and then feeds back to the phase adjustment device 412 of the material cart assembly 4. The working principle of the phase adjustment device 412 is as follows: First, the phase adjustment device 412 consists of a fixed wheel 4122 and a moving wheel 4121, powered by air pressure. Second, when the data information obtained by the control system 8 is analyzed and a large deviation in block height is found in a certain range, the data is uploaded to the control system 8. After computer analysis, the position of the anti-arch rod 411 is changed by rotating the phase adjustment device 412. For example, if the forming main machine produces a 4-row, 4-column block sheet, and the block height detection mechanism 5 detects that the height of the previous column of this block sheet is low, the data is uploaded to the control system 8. After computer analysis, it is determined that the cause is uneven material feeding by the material cart, resulting in insufficient material in the previous mold cavity. Feedback is then sent to the phase adjustment device 412 of the anti-arch mechanism 41. Through pneumatic transmission, air enters through the second air inlet 4127 of the phase adjustment device 412 and exits through the first air inlet 4123. At this time, the high air pressure in the right air chamber of the phase adjustment device 412 causes the driving wheel 4121 to rotate counterclockwise, causing the arch-breaking rod 411 to shift backward, thereby increasing the feeding amount of the front mold cavity, making the material distribution more uniform, and reducing the height error of the blocks.
