Description

Technical Field

[0001] This utility model relates to the technical field of block processing equipment, specifically a surface treatment device for autoclaved aerated concrete blocks. Background Technology

[0002] Industry Background and Technological Importance: Autoclaved aerated concrete (AAC) blocks, as a high-performance lightweight, thermally insulating, and fire-resistant building material, are increasingly widely used in modern construction. In its production process, the precise cutting of large, initially set blocks is a key step in achieving the final product's dimensions.

[0003] During the cutting process, a large amount of debris and fine dust is inevitably generated. These cutting residues adhere tightly to the cut surfaces and grooves of the block blanks. If not effectively removed, they will lead to a series of serious problems:

[0004] Residues can damage the flatness and smoothness of the block surface, reducing the product's appearance grade. During subsequent autoclaving, residues may cause defects, pitting, or even affect the uniformity of the internal structure on the block surface.

[0005] Dust adhering to the surface can significantly reduce the bonding strength between the blocks and the mortar, resulting in insufficient mortar joint fullness, which affects the integrity and seismic performance of the masonry structure. Dust also deteriorates the construction site environment, which does not meet the requirements of green construction. Additional cleaning steps or rework may be required later, increasing production costs.

[0006] Currently, the industry mainly relies on the following methods for surface cleaning of AAC preforms after cutting:

[0007] Operators currently use compressed air blowing, brush cleaning, or simple wiping methods for cleaning. These methods suffer from significant drawbacks, including high labor intensity, low efficiency, inconsistent cleaning results, and harsh working environments, making them unsuitable for the demands of modern, large-scale, high-efficiency production lines. Some relatively simple cleaning devices exist, such as fixed air vents or simple brush rollers. However, their structural dimensions and the positions of cleaning components are often fixed or have extremely limited adjustment ranges, failing to flexibly adapt to different specifications of AAC preforms. When the production line switches product models, the equipment either cannot effectively cover the cleaning area or requires significant time for complex mechanical adjustments or even component replacements, severely restricting production efficiency and equipment utilization.

[0008] Therefore, there is a need for a device that can be used for cleaning various sizes of blocks. Utility Model Content

[0009] Based on this, this solution provides a surface treatment device for autoclaved aerated concrete blocks, which can automatically measure the size of the blocks and then automatically adjust the spacing of the rotating brushes to perform surface cleaning operations on blocks of different sizes.

[0010] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0011] A surface treatment device for autoclaved aerated concrete (AAC) blocks includes: a controller, a conveying mechanism, and a dimensional detection mechanism and a cleaning mechanism mounted on the conveying mechanism. The dimensional detection mechanism has a positioning component in the feeding direction to place the block in the middle position. The cleaning mechanism has an adjustment structure and rotating brushes in the length, width, and height directions.

[0035] Example 1

[0036] Operators currently use compressed air to blow away debris, brushes to clean, or simple wiping methods. This approach is labor-intensive, inefficient, produces inconsistent cleaning results, and operates in harsh environments. Furthermore, the cleaning equipment itself is simple in structure, requiring cumbersome disassembly and assembly processes for different products. Therefore, a more user-friendly cleaning device has been designed, capable of automatically detecting block dimensions and making automatic adjustments. The specific solution is as follows:

[0037] like Figure 1-4As shown, a surface treatment device for autoclaved aerated concrete blocks includes: a controller, a conveying mechanism 2, and a size detection mechanism and a cleaning mechanism mounted on the conveying mechanism 2. The size detection mechanism has a positioning component 3 in the feeding direction to place the block in the middle position. The cleaning mechanism has an adjustment structure and a rotating brush 7 in the length, width, and height directions. The adjustment structure and the size detection mechanism are respectively connected to the controller. The size detection mechanism has measuring components in the length, width, and height directions to measure the length, width, and height of the block. The measurement data is sent to the controller. The controller controls the adjustment structure to adaptively adjust the rotating brush 7 in the length, width, and height directions to suit the current size.

[0038] The positioning component 3 includes a positioning cylinder 301 and a positioning plate 302. The positioning cylinder 301 is a telescopic cylinder. The positioning plate 302 is fixedly connected to the telescopic end of the positioning cylinder 301. The positioning cylinder 301 is installed on both sides of the conveying mechanism 2. The telescopic cylinder is also provided with guide components 303 of sliding rods and linear bearings on both sides, so that the positioning plate 302 can slide smoothly.

[0039] The conveying mechanism 2 is a stepping conveyor belt, which can stop the blocks while conveying them and work with the equipment components to complete the operation. In this embodiment, the conveying mechanism 2 is divided into two linked conveyor belts, and a rotating brush 7 is provided at the section to clean the bottom surface of the blocks.

[0040] The size detection mechanism includes a support, a length detection component 6, a width detection component 4, and a height detection component 5. The support is erected above the conveying mechanism 2, the height detection component 5 is mounted on the support, the width detection component 4 is mounted on both sides of the conveying mechanism 2, and the length detection component 6 is located on one side of the conveying mechanism 2. The length detection component 6 is used to detect the length of the block, the width detection component 4 is used to detect the width of the block, and the height detection component 5 is used to detect the height of the block. In this embodiment, the size detection mechanism can be controlled independently, mainly to reduce the power consumption of the equipment. When there are a relatively large number of blocks of the same size, the size detection mechanism can detect the size of the first block, without the need to detect the size of each block.

[0041] The length detection component 6 includes a front baffle 601 and a rear baffle 602. The rear of the front baffle 601 is connected to a first drive to control the front baffle 601 to extend into the conveying mechanism 2. The rear of the rear baffle 602 is connected to a second drive, and the bottom of the second drive is connected to a length displacement drive. The first drive includes a rotary cylinder 603 to control the front baffle 601 to enter or exit the conveying mechanism 2. The second drive includes a rotary cylinder 603 and a linear robot. The rotary cylinder 603 is used to control the rotation of the rear baffle 602, so that the rear baffle 602 moves in or out. The linear robot controls the forward and backward displacement of the rotary cylinder 603 so that the rear baffle 602 can contact the rear of the block.

[0042] The width detection component 4 includes a width displacement drive 402 and a clamping plate 401. The clamping plate 401 is installed on the movable part of the width displacement drive 402. The width displacement drive 402 is a lead screw motor component. The lead screw of the lead screw motor component has two sections of threads with the same stroke direction but opposite directions. A slider is slidably connected to each section of thread. A connecting rod 403 is provided between the clamping plate 401 and the slider for fixing the two together. The drive component of the lead screw adopts a servo motor to achieve precise displacement. A guide component 303 is also provided below the width displacement drive 402. The two clamping plates 401 share a guide rod 404. Linear bearings that match the guide rod 404 are respectively installed on the connecting rods 403 on both sides. The two ends of the guide rod 404 are fixedly connected to the frame 1 to make the clamping plate 401 slide smoothly.

[0043] The height detection component 5 includes a height displacement drive 501 and a pressure plate. The pressure plate is fixedly connected to the movable part of the height displacement drive 501. Similarly, the height displacement drive 501 adopts a lead screw motor component. The slider of the lead screw motor component is fixedly connected to the pressure plate. Guide components 303 are also provided on both sides of the pressure plate to ensure that the pressure plate is stable.

[0044] The length detection component 6, the width detection component 4, and the height detection component 5 are all equipped with contact sensors on the structure that contacts the blocks to determine whether they are in contact with each other.

[0045] The cleaning mechanism is equipped with at least one set of rotating brushes 7 corresponding to the length, width and height of the block. Each set of rotating brushes 7 is equipped with two corresponding suction pipes 11. The suction pipes 11 are connected to an external negative pressure vacuuming device. On the frame 1, the suction pipes 11 are fixedly connected to the frame 1 through a mounting plate to keep the position of the suction pipes 11 fixed. Specifically, each set of rotating brushes 7 is equipped with two roller brushes. Each roller brush is connected to a drive motor 8, which controls the rotation of the brush.

[0046] The width-direction rotating brush 7 is connected to the upper drive motor 8 via a width adjustment drive 12. The width adjustment drive 12 has the same structure as the width displacement drive 402, controlling the two brushes to move towards or away from each other. The height-direction rotating brush 7 is also connected to a telescopic cylinder for lifting. The extension and retraction of the telescopic cylinder realizes the lifting and lowering of the brush. The length-direction rotating brush 7 has a first forward / backward cylinder connected to the front brush, which allows the brush to enter or exit the conveying mechanism 2. The rear brush is connected to a second forward / backward cylinder 13 and a second linear robot 604, which are used to control the forward / backward displacement and the front-back displacement of the brush, respectively. The first forward / backward cylinder and the second forward / backward cylinder 13 are both telescopic cylinders.

[0047] The cleaning mechanism is equipped with a dust cover 10. The front and rear sides and the top of the dust cover 10 are openable to facilitate internal maintenance. Specifically, the dust cover 10 is composed of multiple panels. The front and rear sides of the dust cover 10 are screwed to one side of the top panel in the left and right directions. The front and rear sides are connected to the other side of the top panel and the other side of the left and right direction panel with buckles for connection and fixation.

[0048] Working principle:

[0049] First, after placing the block on the conveying mechanism 2, start the conveying mechanism 2. The block will be conveyed in the cleaning direction. When the block moves to the positioning component 3, the positioning cylinder 301 drives the positioning plate 302 to clamp the block, which can correct the block and keep the block on the conveying mechanism 2 in a straight line.

[0050] After the block is calibrated, it is moved to the width detection component 4. The width displacement drive 402 causes the clamping plate 401 to contact both sides of the block. The width is determined by the displacement data of the clamping plate 401.

[0051] After the width is detected, the block is moved to the height detection component 5. The height displacement drive 501 causes the pressure plate to contact the top surface of the block, thereby determining the height of the block through the displacement data of the pressure plate.

[0052] After the height is detected, the block moves toward the length detection component 6. At this time, the front baffle 601 falls down, the block moves and contacts the front baffle 601, and the rear baffle 602 falls down and is displaced by the linear robot until the rear baffle 602 contacts the rear side of the block. The length of the block is then determined by the displacement data of the rear baffle 602.

[0053] The corresponding length, width, and height data are centrally processed by the controller, which then adjusts the direction of the cleaning mechanism accordingly to fit the size of the blocks. This eliminates the need for operators to input the corresponding dimensions, making the equipment more convenient to use.

[0054] After the blocks enter the cleaning mechanism, the left and right sides of the blocks are cleaned first, then the top and bottom surfaces of the blocks are cleaned, and finally the front and back surfaces of the blocks are cleaned, ensuring that all six sides of the blocks are cleaned.

[0055] The surface treatment device in this solution measures the dimensions of the current block using length, width, and height detection components and transmits the data to the controller. Based on this data, the controller automatically controls the adjustment structure in the cleaning mechanism to adjust the position of the rotating brushes 7 in the length, width, and height directions in real time. The cleaning mechanism is equipped with a dust cover 10 to prevent dust generated during the cleaning process from flying outwards and reduce pollution of the working environment.

[0056] The positioning component 3 at the feed end of the conveying mechanism 2 ensures that the block is centered on the conveying line, ensuring accurate reference for subsequent size inspection and cleaning.

[0057] The length, width, and height detection components are not affected by dust or other factors during operation. They utilize the front and rear baffles 602, clamping plates 401, and pressure plates to contact the blocks, and work with displacement drive and contact sensors to measure the block dimensions.

[0058] The dimensional inspection mechanism can be shut down independently, avoiding repeated inspections of blocks of the same size, reducing the power consumption of the equipment and minimizing wear on mechanical parts.

[0059] Example 2

[0060] In this embodiment, the structure of the surface treatment device is basically the same as that in Embodiment 1. The difference is that the length, width and height detection components are integrated on a liftable bracket. When the first block is moved into place, the bracket is lowered, and the length, width and height dimensions of the block are detected at once by the length, width and height detection components, thereby improving the detection efficiency.

[0061] Example 3

[0062] In this embodiment, the structure of the surface treatment device is basically the same as that in Embodiment 1. The difference is that a dust cover 10 is provided separately outside the size detection mechanism, and the internal length, width and height detection components are replaced by laser range sensors, which can improve the speed of the conveying mechanism 2 and is suitable for high-efficiency production. The dust cover 10 is set for the laser range sensor to ensure its normal operation and avoid excessive dust and detection errors.

[0063] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
