Description

Technical Field

[0001] This utility model relates to the field of construction tools, and in particular to an automatic block sawing machine. Background Technology

[0002] With the innovation and development of the construction industry, traditional red bricks and sand-lime bricks have gradually lost their dominant position in the field of wall materials, and have been replaced by building blocks with larger specifications and better performance. These blocks have become an indispensable part of modern construction projects due to their own advantages. Among them, ordinary concrete small hollow blocks, lightweight aggregate concrete small hollow blocks, and autoclaved aerated concrete blocks are widely used in various construction projects.

[0003] In actual construction, due to the inherent dimensions of building blocks, cutting is often necessary when constructing or installing the top and edges of walls. Currently, the industry commonly uses hammering or sawing for this purpose. However, this traditional method has many problems: on the one hand, building blocks and panels are easily broken due to uneven force during hammering and sawing, resulting in material waste; on the other hand, frequent sawing accelerates saw tooth wear, causing them to become dull quickly and significantly increasing construction costs. More seriously, both the impact of hammering and the friction during sawing generate a large amount of dust. This dust not only pollutes the construction site environment but also causes irreversible health damage to construction workers' respiratory systems and other systems over long-term operation, posing a potential threat to their lives and health.

[0024] Example 1, see appendix Figure 1-4An automatic block sawing machine includes a base 1, a sawing platform 2, and an automatic sawing and dividing mechanism 04. The automatic sawing and dividing mechanism 04 includes a vertical support 4, a lower disc wheel 42, an upper disc wheel 41, and a steel band saw blade 43. The vertical support 4 is installed on one side of the base 1. The lower disc wheel 42 is rotatably installed on the lower part of the vertical support 4, and the upper disc wheel 41 is rotatably installed on the upper part of the vertical support 4. The steel band saw blade 43 is fitted between the upper disc wheel 41 and the lower disc wheel 42. Both the lower disc wheel 42 and the upper disc wheel 41 are made of large-sized wheels to provide sufficient cutting clearance between the saw blades on both sides of the steel band saw blade 43. The sawing platform 2 has a long sawing hole 21 along its length in the middle. A push block 22 is vertically provided at the end of the sawing platform 2. The long sawing hole 21 extends and passes through the push block 22. The blocks are pushed forward by the push block 22. 3. A handle 23 is provided on the outer side of the vertically inserted sawing hole 21 and the push block 22. By holding the handle 23, the sawing platform 2 is pushed forward, thereby moving the block on the sawing platform 2 toward the rotating steel band saw blade 43. Two guide rails 11 are arranged side by side at the upper end of the base 1. Rollers 24 are provided on the bottom surface of the sawing platform 2 and supported on the surface of the guide rails 11. The sawing platform 2 moves along the guide rails 11 via the rollers 24. A limiting plate 12 is provided on the inner edge of the guide rails 11. A limiting wheel 25 is provided on the inner side of the rollers 24 via the vertical shaft 26. The limiting wheel 25 is supported on the inner side of the guide rails 11 and is located below the limiting plate 12. The limiting wheel 25 restricts the lateral movement of the sawing platform 2, allowing it to move stably in a straight line along the guide rails 11. At the same time, the limiting plate 12's limiting effect on the limiting wheel 25 prevents the sawing platform 2 from separating upward from the guide rails 11.

[0025] The lower disc wheel 42 has a driven wheel 45 on the outer end of its axle. A geared motor 44 is provided on one side of the driven wheel 45. A drive wheel 441 is provided on the drive shaft of the geared motor 44. A belt 46 connects the drive wheel 441 and the driven wheel 45. The geared motor 44 drives the drive wheel 441 to rotate. The drive wheel 441 drives the driven wheel 45 to rotate through the belt 46. The driven wheel 45 drives the lower disc wheel 42 to rotate, which in turn drives the steel band saw blade 43 to rotate between the lower disc wheel 42 and the upper disc wheel 41.

[0026] The upper end of the vertical support 4 is provided with a box 491, and the upper disc wheel 41 is installed inside the box 491. The box 491 is provided with a door 492, which encloses the steel band saw blade 43 to ensure safety during operation.

[0027] When using the automatic block sawing machine of this embodiment, the reduction motor 44 is started first, driving the steel band saw blade 43 to rotate at high speed between the upper disc wheel 41 and the lower disc wheel 42. Then, the block is placed on the sawing platform 2 and abuts against the inner side of the push block 22. Then, the handle 23 is held and the sawing platform 2 is pushed forward. The sawing platform 2 moves along the guide rail 11 toward the steel band saw blade 43. After the block comes into contact with the steel band saw blade 43, the block is gradually cut under the pushing force of the push block 22. This sawing method is more accurate than the cutting method of the cutter and can ensure that the block forms a flat cross-section, which is beneficial to improving the block division quality and reducing material loss.

[0028] Example 2, see appendix Figure 1-3 This embodiment is basically the same as the first embodiment, and the similarities will not be repeated. The difference is that: the base 1 is provided with a dust suction pipe 31. The upper end of the dust suction pipe 31 is directly opposite the passage of the steel band saw blade 43 through the sawing hole 21. The dust suction pipe 31 is a plastic corrugated pipe, which facilitates the convenient adjustment of the length and curvature of the dust suction pipe 31. The lower end of the dust suction pipe 31 is provided with a suction fan 32, which is installed on the side plate 13 of the base 1.

[0029] The suction fan 32 generates negative pressure inside the suction pipe 31, and generates suction force at the inner end of the suction pipe 31. This suction force is used to promptly absorb and collect the sawn block debris and dust, preventing them from polluting the construction site environment and ensuring that construction personnel are in a safe and healthy construction environment.

[0030] Example 3, see appendix Figure 5-7 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the upper part of the vertical support 4 is provided with an upper limit mechanism 47. The upper limit mechanism 47 includes two upper clamping wheels 474 arranged side by side and clamped on both sides of the steel band saw blade 43 and a vertical support rod 472. The vertical support 4 is provided with a fixed seat 471. The upper end of the vertical support rod 472 is fitted into the fixed seat 471. The fixed seat 471 is a bushing seat. The vertical support rod 472 can be mounted on the shaft. The height can be adjusted by sliding up and down inside the sleeve. The lower end of the vertical support rod 472 is provided with an L-shaped bracket 473, and two upper clamping wheels 474 are installed in the L-shaped bracket 473. The L-shaped bracket 473 is provided with two square holes 479 side by side. The two upper clamping wheels 474 are respectively installed in the two square holes 479 through bolt shafts 450. The gap between the clamping wheels is adjusted by bolt shafts 450 to match the thickness of the steel band saw blade 43, ensuring the clamping and limiting effect of the two upper clamping wheels 474 on the steel band saw blade 43.

[0031] A horizontal support rod 475 is provided between the L-shaped bracket 473 and the vertical support rod 472. The end of the horizontal support rod 475 is provided with a side rear stop wheel 476 that supports the rear of the steel band saw blade 43. The rear stop wheel 476 supports the steel band saw blade 43 from the rear. Because the block contacts the steel band saw blade 43 from the front for sawing, it will exert a backward thrust on the steel band saw blade 43. The rear stop wheel 476 can stably support the steel band saw blade 43 and prevent it from slipping off the disc wheel.

[0032] The end of the horizontal support rod 475 is provided with an elongated hole 477, and the lower part of the vertical support rod 472 is provided with a through hole. A fastening bolt 478 is provided between the through hole and the elongated hole 477. The elongated hole 477 on the horizontal support rod 475 can adjust its extension length so that the two upper clamping wheels 474 can be accurately clamped on both sides of the steel band saw blade 43.

[0033] The lower part of the vertical support 4 is provided with a lower limit mechanism 48, which includes two lower clamping wheels 483 arranged side by side. The lower part of the vertical support 4 is provided with two L-shaped baffles 481 arranged side by side. An end plate 482 is provided between the outer ends of the two L-shaped baffles 481. The two L-shaped baffles 481 are fixedly connected into one piece by the end plate 482 to form a U-shaped sleeve structure. The steel band saw blade 43 passes through the U-shaped sleeve structure. The two lower clamping wheels 483 are installed on the inner side of the end plate 482 and clamped on both sides of the steel band saw blade 43.

[0034] In this embodiment, the upper limit mechanism 47 clamps the band saw blade 43 with two clamping wheels to prevent it from swaying during operation and ensure the stability of the sawing. The rear stop wheel 476 rolls from the rear to support the band saw blade 43, which is used to counteract the thrust when sawing blocks and prevent the band saw blade 43 from slipping off the disc wheel. During the rotation and sawing process of the band saw blade 43, the two lower clamping wheels 483 rotate and clamp it. The clamping force of the two lower clamping wheels 483 ensures that the lower part of the band saw blade 43 is in a stable state and prevents it from swaying.

[0035] In this embodiment, the upper limit mechanism clamps the band saw blade with two clamping wheels to prevent it from swaying during operation and ensure the stability of the sawing. A rear stop wheel is also provided to support the band saw blade from the rear, counteracting the thrust during block sawing and preventing the band saw blade from slipping off the disc wheel. During the rotation and sawing process of the band saw blade, the two lower clamping wheels rotate and clamp it. The clamping force of the two lower clamping wheels ensures that the lower part of the band saw blade is in a stable state and prevents swaying.
