Description

Technical Field

[0001] This invention relates to the field of concrete block cutting technology, specifically to a cutting device for concrete blocks used in construction. Background Technology

[0002] Concrete blocks for construction are precast wall building materials made by mixing cement as a binder with raw materials such as sand, gravel, fly ash, ceramsite, and recycled aggregates, followed by mixing, molding, and curing. They include ordinary concrete small hollow blocks, autoclaved aerated concrete blocks, and lightweight aggregate concrete blocks, among others. They offer advantages such as controllable weight, thermal and sound insulation, fire resistance and durability, convenient construction, and compatibility with prefabricated buildings. They are widely used for interior and exterior walls, partitions, infill, and low-rise load-bearing structures. During construction, they often need to be cut to size according to site dimensions. (A matching concrete block cutting tool is also available.) The equipment is divided into handheld electric cutting machines for construction sites, tabletop stone cutting machines, manual block splitting machines, and CNC gantry cutting production lines for factories. Most of the equipment is equipped with diamond saw blades and features water-cooled dust removal, laser positioning, servo adjustment, and other structures. It can accurately cut concrete blocks of different specifications and materials. It can quickly trim small blocks on-site and also cut large blocks into standard masonry sizes in batches. It effectively controls cutting errors, reduces dust and waste, and improves cutting efficiency and construction safety. It is an indispensable special-purpose supporting machine for block processing and masonry construction.

[0003] Chinese patent CN222697480U discloses an adjustable concrete block cutting device, including a cutting mechanism body. Two protruding strips are mounted on the top of the cutting mechanism body, and an adjusting device is slidably fitted onto the surface of each protruding strip. A fixing device is mounted on the top of the adjusting device. The adjusting device includes two sliding plates that slidably fit onto the surface of the protruding strips. By using the sliding plates and protruding strips, the sliding plates can move on the protruding strips, allowing the concrete block to move left and right on the top of the cutting mechanism body. The sliding plates, fixing plate, and baffle allow the fixing plate and baffle to move on the sliding plates. This allows the clamping mechanism to be adjusted according to different sizes of concrete blocks, reducing frequent adjustments to the clamping mechanism, improving cutting accuracy and efficiency, and increasing its stability and precision. The technical solution lacks a local adaptive buffer structure during clamping, resulting in local stress concentration. This can easily lead to surface crushing and chipping of brittle concrete blocks like aerated concrete blocks. Furthermore, in existing technologies, the specifications and heights of material collection carts and turnover baskets at construction sites vary, and the height of the equipment's unloading pallet cannot be adapted to various material holding containers. After the blocks are cut, workers can only reach out and pick them up by bending over, which not only involves high manual labor intensity but also poses safety hazards such as squeezing and scratching when their hands are close to the cutting station.

[0005] This invention provides a cutting device for concrete blocks used in construction. It has the following advantages: 1. The cutting equipment for concrete blocks used in this building is designed for aerated concrete blocks and hollow concrete blocks, which are brittle. Rigid clamps are prone to overloading and squeezing the surface due to clamping force, resulting in a large amount of brick debris and edge cracking. In the existing technology, rigid clamps have no buffer margin, and the blocks are prone to slight slippage and lifting when clamped. By relying on springs to continuously provide uniform pre-tightening force, the blocks will not shift during the cutting process, and the cutting length and cross-sectional flatness are stable.

[0006] 2. The concrete block cutting equipment used in this building converts excess clamping force into spring compression after the positioning plate contacts the block, limiting the maximum clamping pressure, avoiding local stress concentration, and preventing the block surface from being crushed or losing powder, thus greatly reducing the accumulation of debris on the workbench.

[0007] 3. The cutting equipment for concrete blocks used in this building has a groove width that accommodates both fine dust and blocky debris, preventing large pieces of brick debris from clogging the groove or blocking the air duct. It maintains a smooth negative pressure adsorption channel, ensuring stable dust collection. After the slag-laden airflow enters the collection rack, the intercepting net blocks solid brick debris and fragments, while clean air passes through the filter and is discharged, achieving centralized accumulation of waste. Workers only need to clean the waste on the intercepting net periodically.

[0008] 4. The cutting equipment for concrete blocks used in this building has inconsistent heights of material carts and turnover baskets at the construction site. By adjusting the overall height of the sliding plate with a cylinder, the drop difference of the blocks can be changed and controlled. It can be adapted to both low material baskets to prevent blocks from falling from a height and chipping corners, and high turnover carts, without the need to raise or move the material containers, adapting to various on-site material cutting conditions.

[0009] 5. The concrete block cutting equipment for this building can lower the inclined plate to a height close to the aggregate container, reducing the vertical drop of the blocks and preventing them from falling directly from a height, which would cause edge breakage and chipping. This improves the finished product integrity rate, reduces waste, and eliminates the need for workers to bend down and reach to pick up the cut blocks. The inclined plate is automatically flipped by a cylinder to unload the blocks, reducing repetitive bending and lifting operations, lowering the labor intensity of workers, and preventing scratches from hands near the cutting area.

[0012] Please see Figures 1-3 This invention provides a cutting device for concrete blocks used in construction, comprising: Guide rollers 6 are evenly arranged in the middle of the top of the workbench 1. Both ends of the guide rollers 6 are rotatably connected to the inner side of the workbench 1. The concrete blocks are placed on the workbench 1 and pushed forward. The guide rollers 6 are provided in the middle of the top surface of the workbench 1. When the blocks move, they are supported and slid by the guide rollers 6, which reduces the friction between the blocks and the workbench 1 surface. A drive unit 5 is fixedly connected to the side of the worktable 1. One end of the lead screw 7 is rotatably connected to the inside of the worktable 1, and the other end of the lead screw 7 is fixedly connected to the output end of the drive unit 5. Guide rods 9 are symmetrically arranged on both sides of the worktable 1. Both ends of the guide rods 9 are fixedly connected to the inside of the worktable 1. After the drive unit 5 is started, the output end of the drive unit 5 drives the lead screw 7 inside the worktable 1 to rotate. The lead screw 7 drives the two sets of positioning components 8 to move towards each other, and at the same time guides them through the guide rods 9. Both sides of the guide rod 9 are slidably connected with positioning components 8. When the block is pushed to the processing station, the two sets of positioning components 8 simultaneously clamp the block to complete the positioning and fixing. A cutting component 3 is fixedly connected to the top of the workbench 1, and a feeding component 4 is fixedly connected to the side of the workbench 1. Then, the cutting component 3 is activated to cut the firmly clamped block. After the cutting is completed, the cut finished block falls onto the feeding component 4. The large pieces of leftover material generated by the cutting stay between the positioning components 8. The finished block can be unloaded with the help of the feeding component 4. Example 1, please refer to Figure 4 The invention also includes a positioning component 8. The concrete blocks are conveyed to the cutting station by the guide roller 6 on the top surface of the workbench 1. The operator pre-marks the required cutting length of the blocks. Positioning frames 81 are symmetrically arranged on both sides of the top of the worktable 1. The lead screw 7 drives the two positioning frames 81 to move relative to each other through the slider. The positioning frames 81 are slidably connected to the side of the guide rod 9 through the slider. The bottom of the positioning frame 81 is fixedly connected to the slider. The positioning frame 81 is slidably connected to the inner side of the worktable 1 through the slider. Then the drive unit 5 is activated. The output shaft of the drive unit 5 drives the lead screw 7 inside the worktable 1 to rotate. The lead screw 7 and the slider at the bottom of the positioning frame 81 form a threaded transmission, driving the left and right sets of positioning frames 81 to move synchronously towards each other. Positioning plates 85 are symmetrically arranged on both sides of positioning frame 81. The side of positioning plate 85 is slidably connected to the inner side of positioning frame 81. Positioning plate 85 is provided on positioning frame 81. Positioning plates 85 on both sides move closer together and press the concrete block on the workbench 1 to complete the positioning and clamping of the block. During the process of the positioning plate 85 contacting the block and continuously applying pressure, the block generates a reverse supporting force that pushes the positioning plate 85 back into the positioning frame 81. Slide rods 82 are evenly arranged on the inner side of the positioning frame 81. One end of the slide rod 82 is fixedly connected to the positioning plate 85, and the other end of the slide rod 82 is slidably connected to the inner side of the positioning frame 81. A circular plate 84 is fixedly connected to the side of the slide rod 82. A first spring 83 is sleeved on the slide rod 82. The positioning plate 85 slides together with the slide rod 82 in the inner cavity of the positioning frame 81. The circular plate 84 at the end of the slide rod 82 moves synchronously and compresses the first spring 83 sleeved on the outside of the slide rod 82. The elastic compression deformation of the first spring 83 absorbs the clamping impact force and realizes elastic buffer clamping. Please see Figures 5-6 The present invention also includes a cutting component 3, a fixed block 33 is fixedly connected to the output end of the drive mechanism 32, and a cutting mechanism 34 is fixedly connected to the side of the fixed block 33. After the block is clamped and positioned on the workbench 1, the cutting mechanism 34 installed on the fixed block 33 is started to make it run. The bottom of the cutting frame 31 is fixedly connected to the workbench 1. The inner side of the cutting frame 31 is fixedly connected to the drive mechanism 32. When the drive mechanism 32 of the cutting frame 31 is turned on, the drive mechanism 32 drives the fixed block 33 and the cutting mechanism 34 to move together to complete the cutting operation of the concrete block. The collection rack 39 is fixedly connected to the side of the workbench 1. A negative pressure fan 38 is fixedly connected to the bottom of the inner cavity of the collection rack 39. Air pipes 36 are fixedly connected to both sides of the top of the collection rack 39. A placement seat 35 is fixedly connected to the top of the air pipes 36. A guide frame 310 is fixedly connected to the inner side of the placement seat 35. The guide frame 310 is set with a low center and high sides. The negative pressure fan 38 inside the collection rack 39 is turned on simultaneously. The fan forms a negative pressure adsorption environment in the inner cavity of the placement seat 35 through the air pipes 36. The guide frame 310 is designed with a low center and high sides to ensure that there is no collision interference when the cutting mechanism 34 moves laterally. The top of the guide frame 310 is evenly provided with a material drop chute, and the middle of the inner cavity of the collection frame 39 is fixedly connected with an interception net 37. The top surface of the guide frame 310 is evenly provided with a material drop chute. The brick slag and debris generated by cutting are driven through the material drop chute by the negative pressure airflow, and sent into the collection frame 39 through the air pipe 36 with the negative pressure airflow. Finally, they are intercepted and accumulated on the interception net 37, realizing the centralized recycling of cutting dust and waste. Please see Figures 7-8 The present invention also includes a feeding component 4, an inclined plate 45 is rotatably connected to the top of the sliding plate 44, and a cylinder 43 is fixedly connected to the middle of the inner side of the feeding rack 41. The output end of the cylinder 43 is fixedly connected to the bottom of the sliding plate 44. After the concrete block is cut, the cut finished block is pushed onto the inclined plate 45. The cylinder 43 is started, and its output end drives the sliding plate 44 to descend along the inside of the feeding rack 41 to a specified height. A second cylinder 46 is fixedly connected to the middle of the sliding plate 44. A sliding frame 47 is slidably connected to the inner side of the sliding plate 44. The bottom of the sliding frame 47 is fixedly connected to the output end of the second cylinder 46. One side of the unloading frame 41 is set as an inclined surface. The unloading frame 41 is fixedly connected to the side of the worktable 1. Inclined plate frames 42 are fixedly connected to both sides of the top of the unloading frame 41. A sliding plate 44 is slidably connected to the inner side of the unloading frame 41. Rotating blocks 48 are rotatably connected to both sides of the bottom of the inclined plate 45. The bottom of the rotating block 48 is connected to the sliding plate 44 through a connecting shaft. The top of the frame 47 is fixedly connected, and then the second cylinder 46 is activated. The output end of the second cylinder 46 drives the sliding frame 47 to move down along the inside of the sliding plate 44. The sliding frame 47 is pulled by the connecting shaft to rotate the block 48 and descend synchronously, thereby driving the inclined plate 45 to flip and deflect inside the sliding plate 44 until the inclined plate 45 is flush with the inclined plate frame 42. At this time, the finished blocks placed on the inclined plate 45 will slide down the plate surface and then be automatically unloaded along the slope of the inclined plate frame 42 on both sides of the unloading frame 41, which greatly reduces the manual handling of blocks. Specific workflow: The concrete block is placed on the workbench 1 and pushed forward. The top surface of the workbench 1 is equipped with a guide roller 6. When the block moves, it is supported and slid by the guide roller 6, which reduces the friction between the block and the workbench 1 surface. After the drive unit 5 is started, the output end of the drive unit 5 drives the lead screw 7 inside the worktable 1 to rotate. The lead screw 7 drives the two sets of positioning components 8 to move towards each other, and at the same time guides them through the guide rod 9. After the block is pushed to the processing station, the two sets of positioning components 8 clamp the block simultaneously to complete the positioning and fixation; Then the cutting component 3 is activated to cut the firmly clamped block. After the cutting is completed, the finished block is dropped onto the unloading component 4. The large pieces of leftover material produced by the cutting remain between the positioning components 8. The unloading component 4 can be used to unload the finished block. Concrete blocks are conveyed to the cutting station via guide rollers 6 on the top surface of workbench 1, and the operator pre-marks the required cutting length of the blocks; Then the drive unit 5 is activated. The output shaft of the drive unit 5 drives the lead screw 7 inside the worktable 1 to rotate. The lead screw 7 and the slider at the bottom of the positioning frame 81 form a threaded transmission, driving the left and right sets of positioning frames 81 to move synchronously towards each other. Positioning plate 85 is provided on positioning frame 81. The two positioning plates 85 simultaneously approach and press the concrete block on the workbench 1 to complete the positioning and clamping of the block. During the process of the positioning plate 85 contacting the block and continuously applying pressure, the block generates a reverse supporting force that pushes the positioning plate 85 back into the positioning frame 81. The positioning plate 85 slides together with the slide rod 82 in the inner cavity of the positioning frame 81. The circular plate 84 at the end of the slide rod 82 moves synchronously and compresses the first spring 83 sleeved on the outside of the slide rod 82. The elastic compression deformation of the first spring 83 absorbs the clamping impact force to achieve elastic buffer clamping. After the block is clamped and positioned on the workbench 1, the cutting mechanism 34 installed on the fixed block 33 is started to operate. Then activate the drive mechanism 32 of the cutting frame 31. The drive mechanism 32 drives the fixed block 33 and the cutting mechanism 34 to move together to complete the cutting operation of the concrete block. The negative pressure fan 38 inside the collection rack 39 is turned on simultaneously. The fan creates a negative pressure adsorption environment in the cavity of the placement seat 35 through the air pipe 36. The guide frame 310 adopts a design that is low in the middle and high on both sides, which can ensure that there is no collision interference when the cutting mechanism 34 moves laterally. The top surface of the guide frame 310 is evenly opened with a material drop chute. The brick slag and debris generated during cutting are carried through the material drop chute by the negative pressure airflow, and then sent into the collection frame 39 through the air pipe 36 with the negative pressure airflow. Finally, they are intercepted and piled on the interception net 37, realizing the centralized recycling of cutting dust and waste. After the concrete blocks are cut, the cut finished blocks are pushed onto the inclined plate 45. The cylinder 43 is started, and its output end drives the sliding plate 44 to descend along the inside of the unloading rack 41 to the specified height. Then, cylinder 46 is activated. The output end of cylinder 46 drives the sliding frame 47 to move down along the inside of the sliding plate 44. The sliding frame 47 is pulled down synchronously by the rotating block 48 via the connecting shaft, which in turn drives the inclined plate 45 to rotate and deflect inside the sliding plate 44 until the inclined plate 45 is flush with the inclined plate frame 42. At this time, the finished blocks placed on the inclined plate 45 will slide down the plate surface and then be automatically unloaded along the slope of the inclined plate frame 42 on both sides of the unloading frame 41, which greatly reduces the manual handling of blocks.
