Description

Technical Field

[0001] This application belongs to the field of aerated concrete block cutting technology, specifically a cutting device for autoclaved aerated concrete blocks. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks are a special type of lightweight building material. They are made from raw materials such as cement, lime, and sand. After mixing, stirring, and pouring, they are manufactured through a high-temperature autoclaving process. These blocks have many advantages, such as being lightweight, high-strength, providing thermal insulation, sound insulation, and being environmentally friendly. Due to their excellent performance, AAC blocks are widely used in building walls, partitions, and infills.

[0003] Typically, autoclaved aerated concrete (AAC) blocks are long and narrow after being autoclaved and removed from the kiln. To meet different usage needs, they need to be cut into smaller pieces. This cutting process requires the use of specialized cutting equipment to ensure that they have the appropriate size and shape.

[0004] For example, utility model patent CN217169173U discloses a cutting device for autoclaved aerated concrete blocks, including: an installation component for installing a support component and a cutting component; a support component for supporting bricks; a first end of the support component is slidably disposed on the installation component; a cutting component for cutting the bricks on the support component; the cutting component is disposed on the installation component; and an adjustment component for adjusting the height of the support component; the adjustment component is disposed at the second end of the support component. This application can complete both vertical and oblique brick cutting. During brick laying, the required angle and size of the blocks to be cut are determined according to the shape and size of the enclosure structure, eliminating the need to mark each block with a ruler. The operation is simple, time-saving, and labor-saving. By adjusting the cutting device, the angle and size of the bricks can be changed, so the angle and size of the cut blocks are standardized, avoiding the probability of unusable blocks due to excessive deviation and reducing material waste.

[0005] However, in actual use, it was discovered that the device works by placing the blocks on a panel and adjusting the support rods and screw rods to adjust the angle of the panel on which the blocks are placed, thereby achieving oblique cutting of the blocks and cutting out blocks of the required angle and size.

[0006] However, the angle adjustment of the device panel requires manual adjustment, which is not only time-consuming and laborious but also affects the cutting efficiency of the blocks. Therefore, a cutting device for autoclaved aerated bricks is provided. Utility Model Content

At the same time, the conveying function of the conveyor belt body can significantly improve the cutting efficiency of the blocks, and the meshing connection design of the pinion and the large gear can make the cutting blade holder stable and fixed after rotating to a certain angle, while the uniform speed of the pinion driving the large gear to rotate ensures the cutting accuracy and stability.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] refer to Figure 1A cutting device for autoclaved aerated concrete blocks includes a conveyor belt body 1, with multiple bottom supports 19 fixedly installed on the bottom surface of the conveyor belt body 1, and mounting housings 2 respectively provided on the left and right sides of the conveyor belt body 1. The multiple bottom supports 19 facilitate the support of the conveyor belt body 1, keeping it away from the ground. The two mounting housings 2 are fitted with covers on the side away from the conveyor belt body 1 by bolts, which facilitates the sealing of the mounting housings 2. When the bolts are removed, the internal structure of the mounting housings 2 can be inspected and maintained.

[0022] refer to Figure 1 , Figure 2 A bearing 3 is fixedly installed on the side of the housing 2 near the conveyor belt body 1. A connecting shaft 4 is fixedly installed through the middle of the bearing 3. A cutting blade holder 5 is fixedly installed at one end of the connecting shaft 4. The bearing 3 facilitates the installation and fixation of the connecting shaft 4, which allows the connecting shaft 4 to drive the cutting blade holder 5 to rotate, and makes it easy to adjust the tilt angle of the cutting blade holder 5.

[0023] refer to Figure 1 , Figure 2 The cutting blade holder 5 is equipped with a cutting mechanism 6, which includes an electric hydraulic rod 10 and a cutting blade 11. The electric hydraulic rod 10 is fixedly installed on the top surface of the cutting blade holder 5. The telescopic end of the electric hydraulic rod 10 passes through the top surface of the cutting blade holder 5, and the cutting blade 11 is fixedly installed on the telescopic end of the electric hydraulic rod 10. When the cutting blade holder 5 is tilted to a certain angle, the operator starts the electric hydraulic rod 10, which drives the cutting blade 11 to move forward. This makes it easier for the cutting blade 11 to cut the block at the tilted position, and the block can be cut to the required angle, improving convenience.

[0024] refer to Figure 1 , Figure 2 A servo motor 7 is fixedly installed on one side of the mounting housing 2 on the left side. The drive end of the servo motor 7 extends into the interior of the mounting housing 2. A small gear 8 is fixedly installed on the drive end of the servo motor 7. A large gear 9 is fixedly installed on the outer surface of one end of the connecting shaft 4 on the left side. The large gear 9 meshes with the small gear 8. The servo motor 7 drives the small gear 8 to rotate. Since the small gear 8 meshes with the large gear 9, it is easy to drive the connecting shaft 4 to rotate, so that the cutting blade holder 5 can drive the cutting mechanism 6 to adjust the angle, so that the cutting mechanism 6 can cut the block at different angles.

[0025] refer to Figure 1 , Figure 2 and Figure 3The conveyor belt body 1 has sliding grooves 12 on its left and right sides respectively. A connecting slider 13 is slidably connected inside the sliding groove 12. One end of the connecting slider 13 is fixed to one side of the mounting housing 2. Fixing components 14 are provided on the left side of the mounting housing 2 respectively. The sliding groove 12 is a T-shaped groove and the connecting slider 13 is a T-shaped block. This makes it easy for the connecting slider 13 to drive the mounting housing 2 to adjust its position back and forth on the side of the conveyor belt body 1, so that the personnel can adjust the mounting housing 2 to a suitable position. The fixing components 14 are used to limit and fix the mounting housing 2 after the position is adjusted.

[0026] refer to Figure 1 , Figure 2 Two limiting rods 15 are movably inserted through the top surface of the cutting blade holder 5, and the bottom ends of the two limiting rods 15 are fixed to the top surface of the cutting blade 11; the two limiting rods 15 make it easier for the cutting blade 11 to be more stable when it is raised and lowered for cutting.

[0027] refer to Figure 1 , Figure 2 and Figure 3 The fixing component 14 includes a mounting plate 16, a locking bolt 17, and threaded holes 18. The mounting plate 16 is fixedly installed on the left and right sides of the mounting housing 2, and a locking bolt 17 is threadedly connected to one side of the mounting plate 16. Multiple threaded holes 18 are opened on the left and right sides of the mounting housing 2, and the locking bolt 17 is threaded into the interior of one of the multiple threaded holes 18. When the mounting housing 2 moves to a suitable position under the action of the connecting slider 13, the personnel can screw the locking bolt 17 into the corresponding threaded hole 18, thus maintaining the stability of the mounting housing 2 and preventing it from moving arbitrarily.

[0028] The implementation principle of the cutting device for autoclaved aerated bricks in this application is as follows: the autoclaved aerated bricks that have been autoclaved and cured and exited the kiln are transported to the conveyor belt body 1. The conveyor belt body 1 is responsible for driving the autoclaved aerated bricks to move forward continuously. When the autoclaved aerated bricks move to the bottom of the cutting mechanism 6, the electric hydraulic cylinder 10 is started, which drives the cutting blade 11 to move downward to cut the autoclaved aerated bricks.

[0029] When it is necessary to change the cutting angle of the autoclaved aerated concrete block, the servo motor 7 drives the pinion 8 to rotate. Since the pinion 8 is meshed with the large gear 9, this rotation will drive the large gear 9 to rotate. The rotation of the large gear 9 will further drive the connecting shaft 4 and the cutting blade holder 5 to rotate, thereby adjusting the tilt angle of the cutting blade holder 5 and the cutting blade 11 to the required position. At this time, the electric hydraulic cylinder 10 will push the cutting blade 11 to move forward, so that the cutting blade 11 cuts the autoclaved aerated concrete block into small beveled pieces according to the adjusted angle.

[0030] The cutting blade holder 5 and the cutting blade 6 of this device can automatically adjust their angles under the drive of the pinion 8 and the gear 9, so that the autoclaved aerated concrete blocks can be easily cut into the required beveled small blocks. At the same time, the conveying function of the conveyor belt body 1 can significantly improve the cutting efficiency of the blocks, and the meshing connection design of the pinion 8 and the gear 9 can make the cutting blade holder 5 stable and fixed after rotating to a certain angle, while the uniform speed of the pinion 8 driving the gear 9 to rotate ensures the accuracy and stability of the cutting.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
