Description

Technical Field

[0001] This invention belongs to the field of building block processing technology, and particularly relates to a cutting device for building blocks. Background Technology

[0002] Building blocks are a new type of wall material made primarily from concrete, aerated concrete, gypsum, and fly ash, through molding and curing. They are primarily used to replace traditional clay bricks for constructing interior and exterior walls, partitions, and enclosure structures, and are a widely used basic component in modern construction engineering. Building block cutting is a crucial process in industrialized building production and on-site construction. The core process involves using specialized cutting equipment and technology to process standard or custom-made blocks into specific specifications that meet the building's dimensions, structural requirements, and aesthetic needs, while ensuring clean cuts and precise dimensions. This lays the foundation for subsequent masonry and installation work, and is an important step in improving the quality and efficiency of building construction.

[0003] Existing building block cutting devices have several shortcomings. For example, some devices lack effective support structures when cutting U-shaped blocks, causing the blocks to wobble during cutting, making it difficult to guarantee cutting accuracy and resulting in inconsistent block quality. Furthermore, the cutting wheel support structures in some devices are inadequate, leading to wheel deviation during prolonged high-speed operation, affecting cutting results, and potentially causing frequent equipment failures and high maintenance costs. This patented building block cutting device is an innovative design addressing these problems and overcoming the deficiencies of existing technologies. Summary of the Invention

Detailed Implementation

[0017] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0018] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0019] Example 1 like Figures 1 to 5 As shown, an embodiment of the present invention provides a cutting device for building blocks, including a base 1, a support frame 2 fixedly connected to the base 1, a motor 3 fixedly connected to the support frame 2, a rotating drum 4 fixedly connected to the output end of the motor 3, a first fixing ring 5 sleeved on the rotating drum 4, and a cutting wheel 6 fixedly connected to the first fixing ring 5. A fixing rod 7 is fixedly connected to the support frame 2, and a collar 8 is fixedly connected to the other end of the fixing rod 7. The collar 8 is coaxial with the rotating drum 4, and the inner wall of the collar 8 is rotatably connected to the rotating drum 4 through a ball bearing (which can support the rotating drum 4 and maintain coaxiality). A block support is provided on the collar 8 to support the block during cutting.

[0020] When using it, the following process is included: Motor 3 starts, outputting power to drive the rotating drum 4 to rotate. Since the cutting wheel 6 is fixed on the first fixed ring 5 connected to the rotating drum 4, the cutting wheel 6 rotates at high speed with the rotating drum 4, providing cutting power for cutting the building blocks. The opening of the U-shaped block is aligned with the cutting wheel 6 for cutting. When a certain degree of cutting is achieved, the block support begins to support the U-shaped block, preventing the block from shaking or shifting due to the cutting force, ensuring the continuous and stable cutting process.

[0021] The collar 8 is rotatably connected to the inner wall of the rotating drum 4 via ball bearings. On the one hand, it provides support for the rotating drum 4, maintains the coaxiality of the rotating drum 4, and makes the rotating drum 4 rotate more smoothly. On the other hand, the block support set on the collar 8 is used to support the block. During the cutting process, the collar 8 also plays an auxiliary support role for the block support, enhancing the stability of the entire support structure.

[0022] Preferably, the rotating drum 4 has several sets of first connecting holes (not shown in the figure) arranged axially, and the first fixing ring 5 has a set of second connecting holes (not shown in the figure). The second connecting holes are connected to one of the sets of first connecting holes by screws. With this arrangement, the position of the first fixing ring 5 can be adjusted, thereby adjusting the position of the cutting wheel 6.

[0023] Specifically, the support frame 2 includes: an L-shaped fixing base 21 and a mounting plate 22; the L-shaped fixing base 21 is fixedly connected to the base 1, and a rib plate 23 is fixedly connected to the edge of the L-shaped fixing base 21; the L-shaped fixing base 21 has a strip-shaped mounting hole 24 and a strip-shaped through hole 25; the mounting plate 22 has a through hole 26, which is bolted to the strip-shaped mounting hole 24; the motor 3 is fixedly connected to the mounting plate 22, and the output shaft of the motor 3 passes through the strip-shaped through hole 25; the fixing rod 7 is fixedly connected to the mounting plate 22. With this configuration, the height of the cutting wheel 6 can be adjusted by adjusting the mounting plate 22.

[0024] For example, the block support includes: an external toothed ring 10, a rack 11, and a support rod 12; the external toothed ring 10 is rotatably connected to the collar 8 via a damping bearing, and the collar 8 has sliding connection holes 13 on both its upper and lower sides, and the rack 11 is slidably connected in the sliding connection holes 13, with both racks 11 meshing with the external toothed ring 10; there are two support rods 12, which are respectively fixedly connected to the two racks 11 on their opposite sides, and each support rod 12 has at least two rollers 14; the end of the support rod 12 is fixedly connected to a diagonal rod 15 (the U-shaped block is fitted onto the support rod 12 through the diagonal rod 15), and the ends of the diagonal rods 15 that are away from the support rod 12 are close to each other.

[0025] The working principle of this setting is as follows: 1. Cutting Action: When the cutting device starts working, the rotating drum 4 rotates under the drive of the motor 3. Since the external gear ring 10 is rotatably connected to the collar 8 through a damping bearing, the rotation of the rotating drum 4 will drive the external gear ring 10 to rotate accordingly. The external gear ring 10 meshes with the racks 11 on the upper and lower sides. When the external gear ring 10 rotates, it will push the two racks 11 to slide along the sliding connection hole 13 on the collar 8. Since the two racks 11 are respectively meshed with the external gear ring 10, and the external gear ring 10 is a ring structure, the two racks 11 will move in opposite directions, that is, synchronously and moving away from each other. The two support rods 12 are respectively fixedly connected to the side of the two racks 11 that are moving away from each other. Therefore, as the racks 11 slide, the two support rods 12 will also move away from each other synchronously. Each support rod 12 is provided with at least two rollers 14 and an inclined rod 15 at the end. When the support rods 12 move away from each other, they can support the U-shaped block from the upper and lower sides. The U-shaped block is attached to the support rod 12 by the diagonal rod 15. This design ensures that the U-shaped block and the cutting wheel 6 can be aligned, which facilitates precise cutting.

[0026] 2. Actions after cutting: After cutting is completed, the cutting wheel 6 stops rotating. Since the external gear ring 10 is connected to the collar 8 through a damping bearing, and the damping bearing is an air damping bearing with a small damping force, the driving force on the external gear ring 10 disappears after the cutting wheel 6 stops rotating. At the same time, due to the small damping force, it will not hinder the removal of the U-shaped block. At this time, the U-shaped block can be easily removed because there is no longer a supporting force to keep the U-shaped block in its original position.

[0027] This design, through the cooperation of the external gear ring 10, rack 11, and support rod 12, achieves synchronous support for the U-shaped block from both the top and bottom, ensuring precise alignment between the U-shaped block and the cutting wheel 6. This guarantees cutting accuracy and helps improve the quality of the cut product. The use of air-damped bearings results in low damping force and low energy consumption, ensuring stable drive of the external gear ring 10 during cutting and preventing obstruction of U-shaped block removal after cutting. This allows operators to quickly remove the cut blocks, improving work efficiency. The meshing transmission of the external gear ring 10 and rack 11 enables simple and effective adjustment of the support structure, making the overall structure of the device compact, reducing additional complex transmission components, lowering manufacturing costs and the risk of failure. Furthermore, it is suitable for U-shaped blocks of different sizes.

[0028] Preferably, the mounting plate 22 is provided with a plurality of sets of snap-fit ​​holes, and the fixing rod 7 is snapped into one set of snap-fit ​​holes, thereby adjusting the angle of the collar 8.

[0029] Furthermore, the system also includes a control system comprising a programmable logic controller (PLC), a motor driver, and a user interface. The PLC, as the core control unit, is electrically connected to the motor driver and receives control commands and outputs signals to precisely control the start, stop, and speed adjustment of the motor 3. The user interface includes a display screen and operation buttons. Operators can input cutting parameters and control commands through the operation buttons. The display screen shows the equipment's operating status, cutting parameters, and sensor feedback data in real time, enabling human-machine interaction and facilitating monitoring and adjustment of the cutting process.

[0030] For example, the cutting wheel 6 is generally circular and thin-disc-shaped, with a diameter of 250-350 mm and a thickness of 8-12 mm, to reduce energy consumption and resistance during the cutting process while ensuring cutting efficiency. The cutting wheel 6 is integrally molded from high-strength, high-hardness tungsten carbide alloy material, with a Rockwell hardness of HRA85-90, possessing excellent wear resistance and impact resistance, effectively extending the service life of the cutting wheel and ensuring good cutting performance in frequent cutting of building blocks. The outer periphery of the cutting wheel 6 is precision ground, with the cutting edge thickness controlled between 0.5-1 mm and the surface roughness Ra not exceeding 0.8 μm, making the cutting edge sharp and smooth, reducing jamming during cutting, and improving the flatness and accuracy of the cut. Preferably, several heat dissipation holes are evenly distributed on the end face of the cutting wheel 6, with a diameter of 3-5 mm and a spacing of 15-20 mm. These heat dissipation holes can effectively dissipate the heat generated by friction during cutting, preventing the cutting wheel from overheating and reducing performance or causing damage.

[0031] Example 2 Unlike Embodiment 1, the block support is configured as follows: the block support includes a swivel ring 9, which is rotatably connected to the outside of the collar 8 via a ball bearing. The upper end of the swivel ring 9 can support the U-shaped block, and the swivel ring 9 can rotate, thereby facilitating the pushing and removing of the block.
