Description

Technical Field

[0001] The invention relates to a wet breaking system for autoclaved aerated concrete. Background Art

[0002] In the autoclaved aerated concrete block production line, in order to obtain block boards of specific sizes, the block blank semi-finished products can be broken before the block boards are steamed. This is because the blank semi-finished products have not yet undergone high-temperature hydration reaction, so the bonding force between adjacent blanks is relatively weak. Based on this situation, when implementing the breaking process, the required breaking force is also lower, and a better breaking quality can be obtained. This breaking method is called "wet breaking".

[0003] The current splitting methods are mainly divided into vertical stacking and horizontal arrangement, both of which have their own advantages and disadvantages. However, in general, how to maintain the front and back morphology of the green body, reduce damage and loss, and obtain a better surface morphology after splitting are problems that need to be solved and optimized in both splitting methods. Moreover, for the actual situation on site, how to ensure that the green body is vertical and does not fall during the splitting process, and how to efficiently clean up the debris and floating dust generated before and after the splitting, is also one of the key points that need to be improved in the splitting system. Summary of the invention

[0004] In order to solve the deficiencies of the prior art, a more complete wet breaking system is now provided, which can be widely used in the preparation of aerated concrete, and the system has a small footprint and high processing efficiency.

[0005] A wet breaking system for autoclaved aerated concrete, comprising a main frame, on which an upper breaking assembly, a blank bearing area and a lower breaking assembly are sequentially arranged;

[0006] The upper breaking subassembly is connected to the main frame through a lifting frame, and an upper breaking walking beam is provided on the top of the lifting frame, and the upper breaking subassembly moves laterally through the upper breaking walking beam;

[0007] The lower breaking assembly is connected to the main frame through the lower frame, and the lower frame includes a lower frame body, a transmission assembly, a plurality of transverse frames and transverse slide rails, wherein the lower breaking assembly realizes transverse movement through the transverse slide rails;

[0008] A cleaning device is provided at the bottom of the blank bearing area, which extends outward. The cleaning device includes a brush plate, a walking assembly and a motor. After the blank is lifted off, the brush plate moves along the length direction of the main frame driven by the walking assembly, and the brush assembly on the brush plate cleans the blank bearing area.

[0009] An upper clamping structure is provided in the upper breaking component, and a lower clamping structure is provided in the lower breaking component. The upper and lower clamping structures constitute a longitudinal clamping unit. The longitudinal clamping unit is used to clamp the blank to be broken, and break the blank into a preset width size through lateral movement.

[0010] In order to reduce the floor space of the device, the lifting frame is connected to the main frame through a lifting cylinder. A transmission assembly is provided in the lower frame, and the transmission assembly includes a plurality of groups of linked transmission rods. The lifting frame includes at least two vertical guide columns and a slider matched with the vertical guide columns. The upper breaking assembly is fixed on the slider, and the top of the vertical guide column is connected to the upper breaking walking beam. The lifting and lowering movement of the upper breaking assembly is realized by sliding the slider on the vertical guide column.

[0011] At the same time, in order to further facilitate the separation process, the upper breaking walking beam realizes lateral movement through a gear rack transmission mechanism driven by a motor. The gear is installed on the upper breaking walking beam, and the rack is fixed on the main frame. The motor drives the gear to roll on the rack, driving the upper breaking walking beam and the upper breaking assembly to move horizontally.

[0012] Furthermore, the transmission assembly includes a motor, a reducer, a coupling and a lead screw. The motor is connected to the lead screw through the reducer and the coupling. The lead screw is threadedly connected to the transverse frame. The motor drives the lead screw to rotate, driving the transverse frame and the lower breaking assembly to move laterally along the transverse slide rail.

[0013] Furthermore, the brush plate includes a base plate and bristles fixed on the base plate, the bristles are made of wear-resistant and elastic material, the base plate is connected to the walking assembly, and the length and density of the bristles are set according to the cleaning requirements of the blank bearing area.

[0014] Furthermore, the upper clamping structure and the lower clamping structure of the longitudinal clamping unit provide clamping force through a pneumatic cylinder or a hydraulic cylinder respectively, and the clamping force can be adjusted according to the material, size and strength of the blank. A pressure sensor is provided to monitor the clamping force in real time.

[0015] Beneficial effects:

[0016] 1. Improve the efficiency of breaking:

[0017] The upper breaking assembly can move laterally: The upper breaking assembly can move laterally through the upper breaking walking beam, which makes it possible to adjust the position more flexibly during the breaking process, quickly and accurately reach the part of the blank that needs to be broken, without the need for frequent manual adjustment of the blank position, thereby saving time and improving the overall breaking efficiency.

[0018] The lower breaking assembly can move laterally: The lower breaking assembly can achieve lateral movement through the lateral slide rail, and cooperate with the lateral movement of the upper breaking assembly to more efficiently break the blanks at different positions, adapt to the breaking of blanks with different size requirements, reduce the time cost of adjusting equipment and blanks, and improve the overall operating speed of the production line.

[0019] Automatic cleaning of the bottom cleaning device of the blank bearing area: After the blank is lifted off, the cleaning device can automatically clean the blank bearing area. The walking assembly drives the brush plate to move along the length direction of the main frame to promptly clean up debris and floating dust generated by the splitting, so as to avoid the accumulation of debris affecting the subsequent placement and splitting of the blank, so that the next splitting can be carried out quickly without manual cleaning, thus improving the continuity and efficiency of production.

[0020] 2. Ensure the quality of splitting

[0021] The upper and lower clamping structures constitute a longitudinal clamping unit: the longitudinal clamping unit composed of the upper and lower clamping structures can firmly clamp the blank to be broken, and can ensure the stability of the blank during lateral movement to break it, without shaking or misalignment, thereby making the breaking process more precise and able to break it according to the preset width size, ensuring the size consistency of each blank after breaking, and improving the quality accuracy of the product.

[0022] The cleaning device keeps the blank bearing area clean: the cleaning device cleans the blank bearing area in time to avoid scratches or contamination of the blank surface by impurities such as debris and floating dust, ensures the surface quality of the blank before and after breaking, reduces problems such as uneven breaking or surface damage caused by impurity interference, and further improves the breaking quality.

[0023] 3. Improve equipment adaptability and stability:

[0024] The overall structural design is reasonable: the upper breaking assembly, the blank bearing area and the lower breaking assembly are arranged on the main frame in sequence. The various parts have clear division of labor and cooperate with each other to form a complete wet breaking system. This layout makes the entire breaking operation process smoother, improves the overall stability and reliability of the equipment, and can adapt to long-term and high-intensity production work.

[0025] The lower frame structure is designed with various functions: the lower frame includes the frame body, transmission components, transverse frame and transverse slide rails, etc. This diversified design not only provides reliable support and guidance for the transverse movement of the lower breaking component, but also ensures the stability and accuracy of the movement of the lower breaking component through a reasonable transmission method. At the same time, the setting of multiple transverse frames may help to disperse the force, improve the overall stability and service life of the equipment, and enable the equipment to better adapt to the breaking needs under different working conditions.

[0026] 4. Reduce labor costs and labor intensity:

[0027] The automatic lateral movement of the upper and lower breaking components and the automatic cleaning function of the cleaning device greatly reduce the need for manual intervention. Operators only need to perform necessary monitoring and operation settings, without the need for tedious manual adjustments and cleaning work, which reduces labor costs and labor intensity, and also reduces the probability of operating errors and production accidents caused by human factors.

DETAILED DESCRIPTION

[0032] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0033] Main frame 1, lifting frame 2, lifting cylinder 21, slide block 22, upper breaking assembly 3, upper breaking walking beam 31, lower breaking assembly 4, lower frame body 41, motor 42, lead screw 43, transverse frame 44, blank bearing area 5, walking assembly 51, brush frame 52, blank 6.

[0034] Specific embodiments of wet breaking system for autoclaved aerated concrete

[0035] The wet breaking system for autoclaved aerated concrete in this embodiment mainly includes a main frame 1, an upper breaking component 3, a body bearing area 5, a lower breaking component 4 and a cleaning device. The main frame 1 serves as the supporting structure of the entire system to ensure that each component is firmly installed and operates stably.

[0036] The main frame 1 is welded with high-strength steel and has sufficient strength and rigidity to withstand various forces during the entire wet breaking process. The design shape and size of the frame are optimized according to the layout of the production line and the size of the blank 6 to ensure that all components can be reasonably installed and work together.

[0037] The lifting frame 2 is composed of two vertical guide columns and a slider 22 that cooperates with the vertical guide columns. The vertical guide columns are made of precision-machined cylindrical steel with a smooth surface to reduce the friction of the slider 22 during the sliding process. The slider 22 is inlaid with a self-lubricating bearing to further improve the smoothness of lifting.

[0038] The upper breaking assembly 3 is fixed to the slider 22 by bolts and other connecting parts, so that the upper breaking assembly 3 can move up and down on the vertical guide column along with the slider 22.

[0039] The upper walking beam 31 is a steel beam structure, which spans over the main frame 1. A gear rack transmission mechanism driven by a motor 42 is installed on its top. The gear is installed on the transmission shaft on the upper walking beam 31 through a key connection, and the rack is fixed to the top crossbeam of the main frame 1 by bolts.

[0040] When the motor 42 is started, it drives the gear to roll on the rack, thereby realizing the lateral movement of the upper breaking walking beam 31 and the upper breaking assembly 3 connected thereto. The motor 42 adopts a variable frequency speed regulating motor 42, and the lateral movement speed can be adjusted according to actual needs, and the speed range is 0-500mm / s to adapt to different breaking process requirements.

[0041] The lower frame body 41 is also welded with high-strength steel to provide stable support for the lower breaking assembly 4. A transmission assembly, a plurality of transverse frames 44 and a transverse slide rail are installed on the frame body.

[0042] The transmission assembly consists of a motor 42, a reducer, a coupling and a lead screw 43. The motor 42 uses a three-phase asynchronous motor 42 with a power of 5kW, and the speed is reduced and the torque is increased by the reducer. The coupling uses an elastic coupling, which can effectively buffer the transmission impact between the motor 42 and the lead screw 43. The lead screw 43 is a high-precision ball screw 43 with a pitch of 10mm, and is connected to the traverse frame 44 by threads.

[0043] The transverse slide rail adopts a linear guide rail, which has good guiding property and wear resistance. The transverse frame 44 is connected to the transverse slide rail through the slider 22, so that the transverse frame 44 can move smoothly along the transverse slide rail under the drive of the lead screw 43.

[0044] The lower breaking assembly 4 is fixed to the transverse frame 44 by bolts, and realizes transverse movement with the movement of the transverse frame 44. The transverse movement speed of the lower breaking assembly 4 and the transverse movement speed of the upper breaking assembly 3 can be independently controlled within a range of 0-300 mm / s, so as to be flexibly adjusted according to the characteristics of the blank 6 and the breaking requirements.

[0045] The blank bearing area 5 is located between the upper breaking component 3 and the lower breaking component 4, and is a platform for placing the blank 6 to be broken. The surface of the bearing area is treated with special anti-slip treatment and is provided with evenly distributed anti-slip grooves. The grooves are rectangular in shape, 5mm in depth, 8mm in width, and 20mm in spacing, so as to increase the stability of the blank 6 in the bearing area and prevent the blank 6 from sliding during the breaking process.

[0046] The brush plate consists of a base plate and bristles fixed on the base plate. The base plate is made of aluminum alloy, which is light and corrosion-resistant. The bristles are made of wear-resistant and elastic nylon material, with a bristle length of 80 mm and a density of 100 per square centimeter. The arrangement of the bristles is designed according to the shape and size of the blank bearing area 5 to ensure that the cleaning area can be fully covered.

[0047] The walking assembly 51 is composed of a guide rail and a slider 22. The guide rail is installed at the bottom of the blank bearing area 5 extending outward along the length direction of the main frame 1. The motor 42 uses a DC motor 42 with a power of 0.5kW, which is connected to the slider 22 through a gear transmission mechanism to drive the slider 22 to move on the guide rail, thereby driving the brush plate to move along the length direction of the main frame 1. The speed of the motor 42 can be adjusted by a speed regulator, and the moving speed range is 0-200mm / s.

[0048] Workflow

[0049] (a) Blank 6 is in place

[0050] The semi-finished aerated concrete body 6 before steam curing is hoisted to the body bearing area 5 , and the body 6 is ensured to be stably placed on the anti-slip groove, and its position corresponds to the clamping position of the upper and lower splitting components 4 .

[0051] (ii) Clamping the blank 6

[0052] Start the lifting frame 2 of the upper breaking assembly 3 to lower the upper breaking assembly 3 until the upper clamping structure contacts the upper surface of the blank 6. Then, the upper and lower clamping structures act simultaneously, and the clamping force is provided by the cylinder to firmly clamp the blank 6. The clamping force is adjusted according to the material, size and strength of the blank 6. The clamping force is monitored in real time by the pressure sensor to ensure that the clamping force is within the appropriate range. Generally, the clamping force is set to 500-2000N to avoid damage to the blank 6 or loose clamping.

[0053] (III) Splitting operation

[0054] The upper breaking assembly 3 and the lower breaking assembly 4 move laterally according to a preset program. The motor 42 of the upper breaking walking beam 31 and the transmission assembly motor 42 of the lower frame are started at the same time, driving the upper and lower breaking assemblies 4 to move laterally in opposite directions, breaking the blank 6 into a preset width size. During the breaking process, the lateral movement speed is adjusted according to the hardness and toughness of the blank 6 to ensure the breaking quality. For harder blanks 6, the movement speed can be appropriately reduced, such as 100-200mm / s; for softer blanks 6, the movement speed can be appropriately increased, such as 200-300mm / s.

[0055] (IV) Lifting and cleaning of blank 6

[0056] After the splitting is completed, the split blank 6 is lifted off the blank carrying area 5. After the blank 6 is lifted off, the motor 42 of the cleaning device is started, and the travel assembly 51 drives the brush plate to move along the length direction of the main frame 1. The brush assembly on the brush plate cleans the blank carrying area 5, and sweeps the debris and floating dust generated during the splitting process into the collection device. The cleaning process continues until the blank carrying area 5 is cleaned and ready for the next splitting operation.

[0057] 4. Control and Monitoring

[0058] The entire wet bending system is equipped with a PLC control system to accurately control and monitor the movement and action of each component.

[0059] Monitoring function

[0060] The clamping force of the upper and lower clamping structures is monitored in real time through pressure sensors, and the pressure data is transmitted to the PLC control system. When the clamping force exceeds the set range, the system will sound an alarm to remind the operator to make adjustments.

[0061] An encoder is installed on each motor 42 to monitor the rotation speed and operating position of the motor 42 in real time and feed back to the PLC control system to achieve precise control and positioning of the movement of each component.

[0062] During the breaking process, the displacement sensor is used to monitor the lateral displacement of the upper and lower breaking components 4 to ensure the accuracy of the breaking size. The displacement measurement accuracy is ±0.02mm.

[0063] As a further improvement, the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
