Description

Technical Field

[0001] This invention relates to the field of board breaking machine technology, and in particular to an aerated concrete board breaking machine and board production line. Background Technology

[0002] During the production of aerated concrete (ACP) billets, a splitting machine is used to separate the adhered billets along the cutting surface. Existing splitting machines typically consist of an installation structure, a splitting assembly, a drive assembly, and a conveying assembly. The drive assembly tilts the splitting assembly to achieve billet separation. However, existing equipment lacks an effective dust control structure designed for the dust generated during billet splitting. This results in a large amount of dust being generated by the vibration of the cutting surface debris and loose particles during separation. This not only pollutes the working environment and endangers the health of operators but also adheres to the moving joints of the equipment, accelerating wear, affecting splitting accuracy and equipment lifespan. Furthermore, the lack of a dust control mechanism coordinated with the splitting action makes it impossible to efficiently address the dust problem at its source. Summary of the Invention

[0003] The main objective of this invention is to propose an aerated concrete panel brick breaking machine and panel production line, aiming to solve the problem of serious dust pollution during the existing aerated concrete panel brick breaking process.

[0004] To achieve the above objectives, the present invention proposes an aerated concrete panel brick breaking machine comprising:

An electromagnetic control valve is connected in series on the high-pressure air pipe.

[0013] In one embodiment, the air outlet end of the jet nozzle is provided with a fan-shaped nozzle head, the spray width of the fan-shaped nozzle head is adapted to the thickness of the blank, and an elastic sealing sleeve is provided around the outer periphery of the jet nozzle, the elastic sealing sleeve being tightly fitted to the inner wall of the mounting groove.

[0014] In one embodiment, the splitting component further includes:

[0015] A flexible coupling element, comprising a flexible capsule and a flexible medium filled within the flexible capsule, the flexible capsule being disposed on a first splitting component and / or a second splitting component, the outer surface of the flexible capsule forming a flexible working surface for contacting a blank; and

[0016] At least one pressure generating structure, the at least one pressure generating structure comprising a movable mass block and a guide rail for guiding the movement of the mass block; the mass block is used to move along the guide rail when the splitting component is tilted, thereby changing the pressure distribution inside the flexible bladder.

[0017] In one embodiment, the guide rail is disposed vertically on the first splitting member and / or the second splitting member, and the mass block is used to abut against the side of the flexible bladder opposite to the flexible working surface to compress the flexible bladder.

[0018] The pressure generating structure also includes a cylinder, the cylinder body of which is disposed on the first splitting component and / or the second splitting component, and the piston rod of the cylinder is connected to the mass block for driving the mass block to move along the guide rail.

[0019] In one embodiment, the splitting assembly includes a first rotating member, a second rotating member, a first baffle, a second baffle, and a connecting rod;

[0020] The first rotating member and the second rotating member are arranged opposite to each other, and the bottom end of the first rotating member is hinged to the mounting structure to form a first hinge axis, and the bottom end of the second rotating member is hinged to the mounting structure to form a second hinge axis; the axis of the first hinge axis and the axis of the second hinge axis are collinear.

[0030] The aerated concrete slab brick breaking machine provided by this invention solves the problems of severe dust pollution and lack of a coordinated dust removal mechanism in existing equipment by adopting an integrated dust removal structure (including a negative pressure adsorption unit and an airflow guiding unit). Specifically, during the brick breaking process, the drive assembly drives the first and second breaking parts, which are arranged opposite each other, to tilt in the same direction, separating multiple bricks along the cutting surface of the brick. At the same time, the conveying assembly continuously conveys the bricks. During this process, the airflow guiding unit set on the first and second breaking parts blows airflow towards the brick breaking contact surface, guiding the dust falling off the cutting surface downwards. Meanwhile, the negative pressure adsorption unit located below the conveying assembly is activated simultaneously, efficiently adsorbing and collecting the dust guided by the airflow through adsorption. By combining airflow guidance and negative pressure adsorption, dust generation is controlled at its source, preventing dust from spreading and polluting the environment. The dust removal structure operates synchronously with the separating action, ensuring that dust is treated in a timely manner, reducing dust adhesion to moving parts of the equipment, and reducing wear. At the same time, this structural design does not affect the normal operation of the separating components, improving separation efficiency, improving the working environment, extending equipment life, and ensuring the stability of separating accuracy.

[0041] This invention proposes a brick breaking machine 100 for aerated concrete panels.

[0042] Please see Figures 1 to 3 In one embodiment, the aerated concrete panel brick breaking machine 100 includes:

[0043] Installation structure 1;

[0044] The splitting assembly 2 includes a first splitting component 11 and a second splitting component 12 that are disposed opposite to each other, and the first splitting component 11 and the second splitting component 12 are respectively movably connected to the mounting structure 1;

[0045] Drive component 3 is connected to splitting component 2 and is used to drive the first splitting component 11 and the second splitting component 12 to tilt in the same direction so that the first splitting component 11 and the second splitting component 12 cooperate to split multiple blanks along the blank cutting surface direction.

[0046] A conveying assembly is disposed between the first splitting member 11 and the second splitting member 12 for conveying multiple blanks between the first splitting member 11 and the second splitting member 12.

[0047] The dust removal structure includes a negative pressure adsorption unit 4 and an airflow guiding unit 5. The negative pressure adsorption unit 4 is located below the conveying assembly and is used to adsorb dust falling during the blank splitting process. The airflow guiding unit 5 is located on the first splitting component 11 and the second splitting component 12 and is used to blow airflow onto the blank splitting contact surface to guide the dust to the negative pressure adsorption unit 4.

[0048] The installation structure 1 serves as the basic support for the entire plate breaking machine, supporting various functional components such as the breaking assembly 2, drive assembly 3, conveying assembly, and dust removal structure. It can be made of high-strength steel and is connected by welding or bolts to form a stable frame structure, ensuring that each component maintains its relative position during operation and providing rigid support for the stable operation of the equipment.

[0049] The splitting assembly 2 is the core component for separating the billet. The first splitting component 11 and the second splitting component 12 are arranged in a relative position and are connected to the mounting structure 1 by means of hinge or sliding connection, respectively, and can rotate or tilt around the connection point at a certain angle. Its shape can be designed as a plate or frame according to the shape characteristics of the billet. The surface in contact with the billet can be made of wear-resistant metal material, and some areas can be provided with an elastic buffer layer to reduce damage to the surface of the billet during the splitting process, while ensuring effective contact with the billet and ensuring that the splitting force can be stably transmitted to the cutting surface of the billet.

[0050] The drive assembly 3 provides power to the splitting assembly 2. It can be a hydraulic cylinder, a pneumatic cylinder 193, or a combination of a motor and a transmission mechanism. Its output end is connected to the first splitting component 11 and the second splitting component 12, respectively. By precisely controlling the magnitude and direction of the driving force, the first splitting component 11 and the second splitting component 12 are driven to tilt in the same direction, so that when they come into contact with the billet, they form a relative force along the cutting surface, thereby cooperating to complete the separation of multiple adhered billets. The power output of the drive assembly 3 can be adjusted according to the adhesion strength of the billets to meet the needs of different working conditions.

[0051] The conveying assembly is located in the space between the first splitting component 11 and the second splitting component 12. Its main function is to continuously and stably convey the billets to be split to the working area of ​​the splitting assembly 2, and after splitting, to convey the separated billets to the next process. It can use conveyor belts, conveyor rollers, or chains, and the conveying surface can be equipped with anti-slip structures, such as rubber protrusions or patterns, to prevent the billets from sliding or shifting during conveying, ensuring that the billets accurately enter the splitting position. The conveying speed can be adjusted according to the overall production rhythm to achieve coordinated operation with the splitting action.

[0052] The dust removal structure, designed to address dust generation during the billet splitting process, comprises a negative pressure adsorption unit 4 and an airflow guiding unit 5. The negative pressure adsorption unit 4 is installed below the conveying assembly and typically includes a closed negative pressure chamber 41, connecting pipes, and a negative pressure generating device (such as a negative pressure fan 43). The conveying surface of the conveying assembly has a channel communicating with the negative pressure chamber 41. When the negative pressure generating device is activated, a negative pressure environment is created within the negative pressure chamber 41, which draws in and collects the dust falling during the billet splitting process through the channel on the conveying surface. The airflow guiding unit 5 is installed on the side of the first splitting component 11 and the second splitting component 12 facing the billet. It can consist of several air nozzles 51 and a high-pressure air source. The outlet direction of the air nozzles 51 is aligned with the splitting contact surface of the billet, blowing a pressurized airflow into this area. This removes dust generated at the cutting surface from the billet surface and guides it to the negative pressure adsorption unit 4 below, effectively capturing the dust before it diffuses, thus achieving source control of the dust.

[0053] The aerated concrete slab brick breaking machine 100 provided by this invention, by adopting an integrated dust removal structure (including a negative pressure adsorption unit 4 and an airflow guiding unit 5), can solve the problems of serious dust pollution and lack of a coordinated dust removal mechanism in existing equipment. Specifically, during the brick breaking process, the drive component 3 drives the first breaking component 11 and the second breaking component 12, which are arranged opposite to each other, to tilt in the same direction and separate multiple bricks along the cutting surface of the brick, while the conveying component continuously conveys the bricks. During this process, the airflow guiding unit 5, which is set on the first breaking component 11 and the second breaking component 12, blows airflow towards the brick breaking contact surface, guiding the dust falling off the cutting surface downwards. Meanwhile, the negative pressure adsorption unit 4, located below the conveying component, is activated simultaneously, and efficiently adsorbs and collects the dust guided by the airflow through adsorption. By combining airflow guidance and negative pressure adsorption, dust generation is controlled at its source, preventing dust from spreading and polluting the environment. The dust removal structure operates synchronously with the separating action, ensuring that dust is treated in a timely manner, reducing dust adhesion to the moving joints of the equipment, and reducing wear. At the same time, this structural design does not affect the normal operation of the separating component 2, improving separation efficiency, improving the working environment, extending the service life of the equipment, and ensuring the stability of the separating accuracy.

[0054] In one embodiment, the negative pressure adsorption unit 4 includes a negative pressure chamber 41, a suction pipe 42, and a negative pressure fan 43. The negative pressure chamber 41 is located inside the frame of the conveying assembly. The conveying surface of the conveying assembly has a plurality of adsorption holes communicating with the negative pressure chamber 41. One end of the suction pipe 42 is connected to the negative pressure chamber 41, and the other end is connected to the inlet end of the negative pressure fan 43.

[0055] It should be noted that the negative pressure adsorption unit 4, as the core adsorption component of the dust removal structure, is specifically composed of a negative pressure chamber 41, a suction pipe 42, and a negative pressure fan 43. The negative pressure chamber 41 is not an independent component but is directly located inside the frame of the conveying assembly. A closed cavity is formed by sealing the internal space of the frame. The frame material can be a high-strength metal compatible with the conveying assembly to ensure the structural sealing and pressure-bearing capacity of the negative pressure chamber 41, preventing negative pressure leakage from affecting the adsorption effect. Several adsorption holes are formed on the conveying surface of the conveying assembly (such as the surface of the conveyor belt or the area corresponding to the gap between the conveyor rollers). These adsorption holes are evenly distributed in the effective working area of ​​the conveying surface. The hole diameter can be designed according to the common size of dust particles, and the adsorption holes are connected to the interior of the negative pressure chamber 41, forming a dust suction channel. The suction pipe 42 is made of wear-resistant and corrosion-resistant pipe material. One end is sealed to the reserved interface of the negative pressure chamber 41 via a flange or quick connector, and the other end is also sealed to the inlet of the negative pressure fan 43, ensuring no airflow loss during negative pressure transmission. The negative pressure fan 43 serves as a negative pressure source and can be either a centrifugal or Roots type fan. It has a stable negative pressure output capability and can quickly create a negative pressure environment in the negative pressure chamber 41 after startup.

[0056] In this embodiment, when dust is generated during the breaking of the billet, the negative pressure fan 43 is activated, creating a continuous negative pressure in the negative pressure chamber 41 through the suction pipe 42. The adsorption holes on the conveying surface then generate suction, which, combined with the airflow from the airflow guiding unit 5, precisely draws the dust into the adsorption holes and into the negative pressure chamber 41. The dust is then transported to subsequent processing stages via the suction pipe 42. This structural design integrates the negative pressure chamber 41 with the conveying component frame, eliminating the need for additional equipment space and simplifying the overall structural layout. The adsorption holes are directly located on the conveying surface, allowing for close-range capture of falling dust and reducing dust diffusion paths. The sealed connection design between components ensures negative pressure stability, improves dust adsorption efficiency, and effectively prevents dust contamination of moving parts or diffusion into the working environment, further ensuring equipment operational stability and operator health.

[0057] In one embodiment, the adsorption pores are distributed in a matrix, and the pore diameter of the adsorption pores gradually increases along the direction close to the first splitting member 11 and the second splitting member 12. The pore openings of the adsorption pores are provided with inverted conical flares, and the inner wall of the flares is provided with spiral guide lines.

[0058] It should be noted that the adsorption holes, as the key channels for the negative pressure adsorption unit 4 to capture dust, are distributed in a matrix on the conveying surface of the conveying assembly. This distribution ensures that the adsorption holes evenly cover the main dust-generating areas during billet splitting, ensuring a relatively balanced distribution of adsorption force at various positions on the conveying surface and preventing local dust from being ineffectively captured due to uneven distribution of adsorption holes. Furthermore, the pore size of the adsorption holes is not uniform, but gradually increases towards the first splitting component 11 and the second splitting component 12. Since the billet splitting action mainly occurs in the area near the first splitting component 11 and the second splitting component 12, the amount of dust generated in this area is usually greater and the particles may be coarser. Larger pore sizes can meet the dust treatment needs of this area. Conversely, areas farther from the splitting components have less dust, and smaller pore sizes ensure adsorption effectiveness while avoiding excessive airflow interference with the stability of the billet conveying. Each adsorption pore has an inverted conical flare at its opening. The inner wall of the flare is not smooth but has a spiral guide pattern. The inverted conical flare expands the air intake range of the adsorption pore, making it easier for surrounding dust to enter the adsorption pore. The spiral guide pattern guides the airflow to form a spiral motion when the airflow carries the dust into the adsorption pore. On the one hand, it can enhance the airflow's ability to entrain dust and reduce the probability of dust accumulation and blockage at the pore opening. On the other hand, it can reduce the resistance when the airflow enters the adsorption pore, ensuring the smoothness of negative pressure adsorption.

[0059] In this embodiment, the dust capture efficiency of the negative pressure adsorption unit 4 is further improved by optimizing the distribution of adsorption pores, the variation of pore size, and the structure of the pore opening: the matrix distribution ensures that there are no dead corners in adsorption, the pore size gradient design adapts to the difference in dust amount in different areas, and the combination of the inverted conical flare and the spiral guide pattern enhances the dust suction capacity and reduces the risk of blockage. The overall structure not only ensures the efficient adsorption of dust in the splitting area, but also avoids adverse effects on the conveying of the blank, effectively improving the practicality and stability of the dust removal structure and extending the cleaning and maintenance cycle of the adsorption pores.

[0060] In one embodiment, the airflow guiding unit 5 includes a plurality of jet nozzles 51 and a high-pressure air pipe. The blank contact surfaces of the first splitting component 11 and the second splitting component 12 are both provided with mounting grooves. The jet nozzles 51 are embedded in the mounting grooves. The air outlet direction of the jet nozzles 51 is towards the blank cutting surface and forms an angle of 30°-45° with the blank surface. One end of the high-pressure air pipe is connected to the jet nozzles 51, and the other end is connected to an external high-pressure air source. An electromagnetic control valve is connected in series on the high-pressure air pipe.

[0061] It should be noted that the airflow guiding unit 5, as a key component for dust guidance in the dust removal structure, is composed of several air nozzles 51 and high-pressure air pipes. The surfaces of the first splitting component 11 and the second splitting component 12 that contact the blank are pre-cut with mounting grooves. The shape of the mounting grooves matches the shape of the air nozzles 51, ensuring that the air nozzles 51 can be stably embedded in the grooves. Furthermore, the outer surface of the air nozzles 51 remains flush with the blank contact surface of the splitting component, preventing protruding structures from scratching the blank or hindering the splitting action. The air nozzles 51 can be made of wear-resistant metal or engineering plastic. The structure of their outlet end is optimized to allow the airflow to be directionally sprayed, with the outlet direction precisely facing the cutting surface of the blank, forming an angle of 30°-45° with the blank surface. This angle design ensures that the airflow effectively blows towards the dust source on the cutting surface, peeling off the debris and loose particles attached to the cutting surface, while preventing the airflow from impacting the blank and causing deviation due to an excessively large angle, or from failing to fully contact the dust due to an excessively small angle. The high-pressure air pipe is made of a material with certain flexibility and pressure resistance, and can be flexibly arranged according to the internal layout of the equipment. One end is connected to each jet nozzle 51 through a sealed joint to ensure that there is no leakage of airflow. The other end is connected to an external high-pressure air source (such as an air compressor) to provide a continuous and stable high-pressure airflow to the jet nozzle 51. At the same time, an electromagnetic control valve is connected in series on the high-pressure air pipe. The valve body can precisely control the opening and closing of the high-pressure air pipe and the airflow pressure. It can be synchronously adjusted according to the start and stop of the splitting action to achieve coordinated coordination between airflow guidance and billet splitting.

[0062] In this embodiment, the accuracy and effectiveness of dust guidance are effectively improved by optimizing the structural design of the airflow guiding unit 5: the embedded design of the jet nozzle 51 ensures the flatness of the contact between the splitting component and the billet; the specific angle of the air outlet direction can efficiently remove dust without affecting the stability of the billet; and the cooperation between the high-pressure air pipe and the electromagnetic control valve enables precise control of the airflow, avoiding ineffective waste of airflow or disconnection from the splitting action. The overall structure can not only blow away the dust on the cutting surface in time and guide it to the negative pressure adsorption unit 4 below, improving dust collection efficiency, but also reduce the interference of airflow on billet conveying and splitting accuracy, further ensuring the overall stability of the equipment operation and the reliability of the dust removal effect.

[0063] In one embodiment, the air outlet end of the jet nozzle 51 is provided with a fan-shaped nozzle head 52, the spray width of the fan-shaped nozzle head 52 is adapted to the thickness of the blank, and an elastic sealing sleeve is provided around the outer periphery of the jet nozzle 51, the elastic sealing sleeve is tightly fitted to the inner wall of the mounting groove.

[0064] It should be noted that the air outlet of the nozzle 51 is equipped with a fan-shaped nozzle head 52. This nozzle head is made of wear-resistant engineering plastic or metal, and its internal flow channel is designed with an arc transition structure, which enables the high-pressure airflow to form a uniform fan-shaped spray surface, rather than the traditional columnar airflow. The spray width of the fan-shaped nozzle head 52 can be adapted to the thickness of common billets to ensure that the airflow spray range can completely cover the cutting surface height of the billet. Dust from the top to the bottom of the billet can be effectively contacted by the airflow, avoiding local dust residue due to insufficient spray range. At the same time, the outer periphery of the nozzle 51 is fitted with an elastic sealing sleeve. This sealing sleeve is made of aging-resistant and elastic rubber or silicone material, and its shape matches the inner wall contour of the mounting groove. When the nozzle 51 is embedded in the mounting groove, the elastic sealing sleeve will fit tightly against the inner wall of the mounting groove to form a ring-shaped sealing structure, filling the gap between the nozzle 51 and the mounting groove.

[0065] In this embodiment, the airflow guiding effect and equipment sealing are further optimized through the design of the fan-shaped nozzle head 52 and the elastic sealing sleeve: the wide spray of the fan-shaped nozzle head 52 can fully cover the cutting surface of the blank, ensuring that dust is stripped away without dead corners, and the design adapted to the thickness of the blank avoids the problem of airflow waste or incomplete coverage; the elastic sealing sleeve effectively blocks the airflow from the gap between the jet nozzle 51 and the mounting groove, ensuring that the high-pressure airflow can be sprayed out from the nozzle head, improving the airflow utilization rate, while preventing dust from entering the mounting groove and causing blockage or component wear. The overall structure not only enhances the comprehensiveness and efficiency of dust guidance, but also extends the service life of the jet nozzle 51 and the mounting groove, ensuring the long-term stable operation of the airflow guiding unit 5.

[0066] In one embodiment, the dust removal structure further includes a dust filtration unit, which is disposed between the suction pipe 42 and the negative pressure fan 43. The dust filtration unit includes a filter housing and a detachable filter cartridge. A guide plate is provided inside the filter housing, and the filter cartridge is detachably connected to the filter housing by a snap fastener. A dust collection drawer is provided at the bottom of the filter housing.

[0067] It should be noted that the dust filtration unit, as a key component of the negative pressure adsorption system for dust treatment, is located between the suction pipe 42 and the negative pressure fan 43 to purify the inhaled dust-laden airflow. Its core components include a filter housing and a filter cartridge. The filter housing is made of a metal material with good sealing performance, forming an independent filtration chamber. Several guide plates are fixed within the chamber; these guide plates are inclined or arc-shaped, guiding the dust-laden airflow to form an orderly flow path within the housing, preventing direct impact on the filter cartridge and avoiding localized wear, while also extending the residence time of the airflow within the housing and improving filtration efficiency. The filter cartridge, as the main filtration element, is made of high-strength filter media, effectively intercepting dust particles in the airflow. It is connected to the filter housing via a snap-fit ​​structure, allowing for tool-free installation and removal of the filter cartridge, facilitating quick replacement and maintenance. A dust collection drawer is located at the bottom of the filter housing. The drawer has a pull-out structure and seals with the opening at the bottom of the housing to collect dust that falls after being intercepted by the filter cartridge, facilitating regular cleaning.

[0068] In this embodiment, the baffle guides the airflow evenly through the filter cartridge, avoiding localized overload and extending the filter cartridge's service life. The detachable filter cartridge design simplifies the maintenance process and reduces operational difficulty. The dust collection drawer can centrally collect the filtered dust, preventing secondary pollution. The overall structure not only ensures the purification effect on dust-laden airflow and protects the negative pressure fan 43 from dust wear, but also improves the equipment's operational efficiency through convenient maintenance design, ensuring the long-term stable operation of the dust removal system.

[0069] In one embodiment, a differential pressure sensor is also provided inside the filter housing. The detection end of the differential pressure sensor is connected to the air inlet side and the air outlet side of the filter cartridge, respectively. The differential pressure sensor is electrically connected to an external controller to monitor the clogging status of the filter cartridge and issue a replacement reminder.

[0070] It should be noted that the dust filtration unit is equipped with an additional differential pressure sensor inside the filter housing. This sensor is made of dust-resistant and interference-resistant industrial-grade material. Its two detection ends are connected to the inlet side (the side where the dust-laden airflow enters the filter cartridge) and the outlet side (the side where the filtered clean airflow exits the filter cartridge) through dedicated detection pipes or interfaces, ensuring accurate acquisition of the real-time air pressure difference across the filter cartridge. The differential pressure sensor is electrically connected to an external controller via wires, transmitting the detected differential pressure data to the controller in real time. The controller has a preset differential pressure threshold range for normal operation of the filter cartridge. When the filter cartridge gradually becomes clogged due to dust interception, the differential pressure across the filter cartridge will exceed the preset threshold. At this time, the controller will trigger an alarm mechanism based on the signal from the differential pressure sensor, issuing a filter cartridge replacement reminder in the form of audible and visual prompts or data pop-ups.

[0071] In this embodiment, the use of a differential pressure sensor enables intelligent monitoring of filter cartridge blockage. Compared to the traditional method of manually inspecting and judging the filter cartridge status, the differential pressure sensor can capture pressure changes on both sides of the filter cartridge in real time and accurately, promptly detecting filter cartridge blockage and preventing a decrease in negative pressure adsorption efficiency or overload damage to the negative pressure fan 43 due to filter cartridge blockage. The linkage alarm design with the external controller allows operators to receive timely replacement reminders without frequent shutdowns for inspection. This ensures the stability of the dust removal system's filtration effect, reduces unnecessary equipment downtime, and improves the overall ease of maintenance and operational reliability of the equipment.

[0072] In one embodiment, the splitting component 2 further includes:

[0073] Flexible coupling member 18 includes a flexible capsule 181 and a flexible medium filled within the flexible capsule 181. The flexible capsule 181 is disposed on a first splitting member 11 and / or a second splitting member 12. The outer surface of the flexible capsule 181 forms a flexible working surface for contacting the blank.

[0074] At least one pressure generating structure 19 includes a movable mass block 191 and a guide rail 192 for guiding the movement of the mass block 191; the mass block 191 is used to move along the guide rail 192 when the splitting component is tilted, thereby changing the pressure distribution inside the flexible bladder 181.

[0075] It should be noted that the flexible coupling element 18 is the core component for achieving high-quality splitting. It mainly consists of a hollow flexible capsule 181 and a flexible medium filled within it. The flexible capsule 181 is typically made of a material with high strength, high elasticity, and wear resistance, such as polyurethane rubber or industrial-grade silicone, and its shape is designed as a bag-like or capsule-like structure that conforms to the working surface of the splitting element. The flexible medium filling the capsule is an incompressible fluid, such as high-viscosity silicone oil or a special gel, which can efficiently and uniformly transmit pressure. The flexible capsule 181 is securely mounted on the first splitting element 11 and / or the second splitting element 12, and its exposed surface directly forms a flexible working surface in contact with the aerated concrete blank, replacing the traditional rigid baffle.

[0076] To drive the flexible coupling 18 to generate a specific pressure distribution, the splitting assembly 2 also integrates at least one pressure generating structure 19. This structure is the intelligent core of the entire system, cleverly utilizing gravity to automatically adjust the pressure. It contains a movable mass block 191, which is typically made of a high-density material, such as a solid steel ball or a heavy metal block, to ensure sufficient weight within a finite volume. The movement trajectory of the mass block 191 is constrained and guided by a specially designed guide rail 192, which can be an arc or inclined groove machined inside the splitting assembly, or a fixed, independent track. When the splitting assembly tilts under the action of the drive assembly 3, the mass block 191 moves from one end to the other along the predetermined path of the guide rail 192 under the action of gravity or other drive components. This displacement process directly acts on the flexible capsule 181, thereby changing the pressure distribution in different regions inside it and forming the pressure gradient required to achieve progressive splitting.

[0077] In this embodiment, the flexible coupling element 18 transforms rigid contact into flexible buffering. The flexible capsule 181, like a highly elastic water cushion, evenly envelops the blank, completely eliminating stress concentration and preventing physical damage such as edge chipping and corner breakage from the source. More importantly, the pressure generating structure 19 automatically creates a pressure gradient from one end to the other within the capsule using gravity. This means that the splitting force is no longer applied abruptly, but rather, like a controlled "pressure wave," it guides the crack to expand smoothly along the predetermined cutting surface in an orderly and gradual manner. This transformation from hard splitting to gentle splitting results in a clean, knife-cut surface after splitting, greatly improving the final quality and appearance of the product.

[0078] In one embodiment, the guide rail 192 is disposed vertically on the first splitting member 11 and / or the second splitting member 12, and the mass block 191 is used to abut against the side of the flexible bladder 181 away from the flexible working surface to compress the flexible bladder 181.

[0079] The pressure generating structure 19 also includes a cylinder 193. The cylinder body of the cylinder 193 is located on the first splitting member 11 and / or the second splitting member 12. The piston rod of the cylinder 193 is connected to the mass block 191 for driving the mass block 191 to move along the guide rail 192.

[0080] It should be noted that the guide rail 192 is typically made of wear-resistant materials, such as hardened metal or polymer. Its cross-sectional shape can be a groove or track that matches the shape of the mass block 191, ensuring that the mass block 191 moves smoothly while being effectively constrained, preventing it from wobbling or detaching in undesirable directions. This vertically arranged guide rail 192 structure ensures that the direction of movement of the mass block 191 is consistent with the height direction of the splitting component, laying the foundation for precise pressure control.

[0081] Mass block 191 is used to abut against the side of flexible capsule 181 opposite to the flexible working surface to compress the flexible capsule 181. This means that mass block 191 is positioned on the "back side" of the flexible capsule 181, i.e., the side that does not contact the blank. The side of mass block 191 facing the capsule can be designed as a plane or a curved surface that matches the curvature of the capsule to achieve surface contact or line contact, thereby transferring the compressive force to the flexible medium inside the capsule more efficiently and evenly. This back-pressure structural design ensures that the force of mass block 191 acts entirely to change the internal pressure of the capsule without directly interfering with the flexible working surface that contacts the blank.

[0082] The pressure generating structure 19 of this embodiment also includes a cylinder 193, providing an active and controllable power source for the movement of the mass block 191. The cylinder body of the cylinder 193 is securely mounted on the main frame of the first splitting component 11 and / or the second splitting component 12, and its mounting position ensures that the movement direction of the piston rod is parallel to the direction of the guide rail 192. The piston rod of the cylinder 193 and the mass block 191 are connected by a connecting member, such as a threaded connection, a snap-fit ​​connection, or a hinged transmission arm, to stably transmit the linear thrust or pull of the cylinder 193 to the mass block 191. By controlling the intake and exhaust of the cylinder 193, the mass block 191 can be precisely driven to move actively, quickly, or slowly along the guide rail 192 in the vertical direction, thereby achieving active, real-time, and programmed control of the internal pressure of the flexible bladder 181.

[0083] In one embodiment, the splitting assembly 2 includes a first rotating member 13, a second rotating member 14, a first baffle 15, a second baffle 16, and a connecting rod 17;

[0084] The first rotating member 13 and the second rotating member 14 are arranged opposite to each other, and the bottom end of the first rotating member 13 is hinged to the mounting structure 1 to form a first hinge shaft, and the bottom end of the second rotating member 14 is hinged to the mounting structure 1 to form a second hinge shaft; the axis of the first hinge shaft and the axis of the second hinge shaft are collinear.

[0085] One end of the connecting rod 17 is connected to the first rotating member 13, and the other end of the connecting rod 17 is connected to the second rotating member 14;

[0086] The first rotating member 13 is provided with a plurality of first connecting members, each of which is hinged to the first rotating member 13. The two ends of each first connecting member are located on both sides of the first rotating member 13, and the plurality of first connecting members are arranged sequentially along the extension direction of the first rotating member 13.

[0087] The second rotating member 14 is provided with a plurality of second connecting members, each of which is hinged to the second rotating member 14. The two ends of each second connecting member are located on both sides of the second rotating member 14, and the plurality of second connecting members are arranged sequentially along the extension direction of the second rotating member 14.

[0088] Each first connector is positioned opposite to a second connector;

[0089] The first baffle 15 is disposed on one end of the first connector and the second connector, and the second baffle 16 is disposed on the other end of the first connector and the second connector;

[0090] One end of the drive assembly 3 is hinged to the mounting structure 1, and the other end of the drive assembly 3 is hinged to the first rotating member 13, so as to drive the first rotating member 13 to rotate around the first hinge axis.

[0091] It should be noted that the connecting rod 17 is made of high-strength metal, and its two ends are connected to the tops of the first splitting component 11 and the second splitting component 12 via hinged structures, forming a movable connection. The bottom ends of the first splitting component 11 and the second splitting component 12 are both connected to the mounting structure 1 via hinges, forming a first hinge axis and a second hinge axis, respectively. The axes of the two hinge axes are parallel and spaced apart, ensuring that the first splitting component 11 and the second splitting component 12 can rotate independently around their respective hinge axes. One end of the drive assembly 3 is hinged to the mounting structure 1, and the other end is hinged to the first splitting component 11. Its power output can drive the first splitting component 11 to rotate around the first hinge axis. Due to the linkage effect of the connecting rod 17, when the first splitting component 11 rotates, it will pull or push the second splitting component 12 through the connecting rod 17, causing the second splitting component 12 to rotate synchronously around the second hinge axis, and the two rotate in the same direction.

[0092] The splitting assembly 2 consists of a first rotating member 13, a second rotating member 14, a first baffle 15, a second baffle 16, and a connecting rod 17. The first rotating member 13 and the second rotating member 14 are arranged opposite each other, and their bottom ends are hinged to the mounting structure 1, forming a first hinge axis and a second hinge axis, respectively. The axes of the two hinge axes are collinear, allowing the first rotating member 13 and the second rotating member 14 to rotate around the same axis. The connecting rod 17 is made of rigid metal, and its two ends are fixedly connected to or hinged to the first rotating member 13 and the second rotating member 14, respectively, to ensure that the two rotate synchronously. The first rotating member 13 has multiple first connecting members arranged sequentially along its extension direction. Each first connecting member is hinged to the first rotating member 13, and its two ends extend out from both sides of the first rotating member 13. The second rotating member 14 has multiple second connecting members with the same structure as the first connecting members, and each first connecting member is arranged opposite to one second connecting member. The first baffle 15 is installed at the same end of the first and second connecting members, while the second baffle 16 is installed at the other end of both, forming a limiting structure for both sides of the billet. One end of the drive assembly 3 is hinged to the mounting structure 1, and the other end is hinged to the first rotating member 13. By driving the first rotating member 13 to rotate around the collinear hinge axis, the second rotating member 14 is driven to rotate synchronously, thereby enabling the first baffle 15 and the second baffle 16 to cooperate in completing the billet splitting.

[0093] In this embodiment, the adaptability and splitting accuracy of the splitting assembly 2 are improved through the combined design of collinear hinge shafts, multiple sets of connectors, and baffles. The collinear hinge shafts ensure that the rotation trajectories of the first and second rotating parts 14 are consistent, reducing action deviations; multiple sets of connectors and baffles distributed along the extension direction can adapt to blanks of different lengths. Through the independent hinge characteristics of each connector, the baffles can better fit the blank surface, avoiding excessive local stress that could lead to blank breakage; the linkage of the connecting rod 17 ensures the synchronicity of the actions of the baffles on both sides. Combined with the power output of the drive assembly 3, uniform separation of the blanks along the cutting surface is achieved, which not only improves the adaptability of the equipment to blanks of different specifications, but also reduces the blank breakage rate and ensures the stability of the splitting quality.

[0094] In one embodiment, the first splitting member 11 is provided with multiple sets of rollers, which are arranged sequentially along the extending direction of the first splitting member 11; and / or

[0095] The second splitting component 12 is provided with multiple sets of rollers, which are arranged sequentially along the extension direction of the second splitting component 12.

[0096] In this embodiment, each roller on the first splitting component 11 is paired with a roller on the second splitting component 12. Each pair of first rollers and second rollers corresponds to a layer of blank. By contacting the blank with the rollers, damage to the blank can be prevented.
