Description

Technical Field

[0001] This utility model relates to the technical field of concrete block cutting, specifically to a cutting device for autoclaved aerated concrete products. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks are porous concrete products made primarily from fly ash, lime, cement, gypsum, and slag, with the addition of appropriate amounts of foaming agents, regulators, and bubble stabilizers. The process involves batching, mixing, pouring, static curing, cutting, and high-pressure autoclaving. AAC blocks are mainly used as a new type of thermal insulation wall material; therefore, they need to be cut before use. However, due to their porous texture, the cutting process generates a large amount of dust, and the cutting tools are relatively soft. Given the material's low strength, edge and corner damage is common during cutting, failing to meet testing requirements and resulting in uneven cut surfaces and inaccurate dimensions. Utility Model Content

[0003] This utility model proposes a cutting equipment for autoclaved aerated concrete products. The dust cover and cover plate can initially isolate the spread of dust and achieve the purpose of dust prevention. In addition, the dust generated during cutting is sealed by the dust cover and then sucked out by the dust suction mechanism to achieve the function of dust removal.

[0004] Therefore, the technical solution adopted is as follows:

[0005] A cutting device for autoclaved aerated concrete (AAC) products includes a frame and a worktable. A laser marking device is fixed on the top of the frame, and a cutting mechanism and a pushing mechanism are fixed on the worktable. A dustproof mechanism is fastened to the pushing mechanism and the cutting position. The dustproof mechanism includes a dust cover, the top of which has a rotatable cover plate. A dust suction mechanism is connected inside the dustproof mechanism. The dust suction mechanism includes a dust suction hopper fixed to the top of the dust cover. The dust suction hopper is connected to an external vacuum cleaner through a dust suction pipe. The vacuum cleaner is fixed to the side wall of the worktable.

[0006] A further technical solution is that the cutting mechanism includes a band saw blade and two saw wheels located at both ends of the band saw blade to drive its rotation. The two saw wheels are rotatably fixed on the top of the worktable and the frame, respectively, and the saw wheels are driven by a drive device.

[0007] A further technical solution is that the driving device includes a first motor, the output end of the first motor is fixed with a driving pulley, the driving pulley is connected to a driven pulley through a synchronous belt drive, the driven pulley is coaxially fixed with the saw wheel, and the first motor is electrically connected to a speed regulator.

[0008] A further technical solution is that the pushing mechanism includes an L-shaped plate, which includes a horizontal plate and a vertical plate. A clamping plate is slidably connected to the horizontal plate, and an mounting block is fixed on the horizontal plate. A screw is threadedly connected to the mounting block. One end of the screw is rotatably connected to the clamping plate and pushes the clamping plate toward or away from the vertical plate by its own rotation. The bottom of the L-shaped plate has a pushing device.

[0009] A further technical solution is that the pushing device includes a fixed plate fixed on the worktable, the fixed plate has a lead screw rotatably connected to it, the bottom of the L-shaped plate is fixed with a lead screw sleeve adapted to the lead screw, the lead screw passes into the lead screw sleeve and is driven by a second motor.

[0010] A further technical solution is that a slide bar is also fixed on the fixed plate, which is parallel to the lead screw, and the slide bar is slidably connected to the L-shaped plate.

[0011] A further technical solution is that the L-shaped plate is provided with multiple reserved slots that match the spacing of the band saw blades.

[0012] A further technical solution is that both the dust cover and the cover plate are made of transparent material.

[0013] The working principle and beneficial effects of this application are as follows:

[0014] 1. The dust cover and cover plate can initially isolate the spread of dust and achieve the purpose of dust prevention. In addition, the dust generated during cutting is sealed by the dust cover and then sucked out by the dust collection mechanism to achieve the function of dust removal. This can reduce dust inhalation, improve the working environment, protect the health of employees, avoid production interference, improve cutting accuracy and product quality, and extend the service life of equipment.

[0015] 2. By electrically connecting the speed regulator to the first motor via a wire, the speed of the first motor can be controlled, thereby adjusting the running speed of the band saw blade. This allows for the selection of a suitable cutting speed, which can greatly reduce the risk of edge and corner damage.

[0016] 3. The laser marking device can generate light to project high-precision laser lines onto the surface of autoclaved aerated concrete blocks, indicating the cutting path. The visible laser assists the operator in adjusting the position of the blocks, ensuring that the cutting dimensions of the specimens meet the requirements and improving cutting accuracy.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figures 1-7 The diagram shows a cutting device for autoclaved aerated concrete (AAC) products, comprising a frame 3 and a worktable 1. A laser marking device 6 is fixed to the top of the frame 3, and a cutting mechanism 4 and a pushing mechanism 9 are fixed to the worktable 1. A dustproof mechanism 5 is fastened to the pushing mechanism 9 and the cutting position. The dustproof mechanism 5 includes a dust cover 51, and the top of the dust cover 51 has a cover plate 52 that can be rotatably opened. A dust collection mechanism 8 is connected inside the dustproof mechanism 5. The dust collection mechanism 8 includes a dust collection hopper 83 fixed to the top of the dust cover 51. The dust collection hopper 83 is connected to an external vacuum cleaner 81 through a dust collection pipe 82. The vacuum cleaner 81 is fixed to the side wall of the worktable 1.

[0028] In this embodiment, by opening the cover plate 52, the autoclaved aerated concrete block to be cut is placed on the pushing mechanism 9, and then the cover plate 52 is closed. At this time, the cutting mechanism 4 is started, and the autoclaved aerated concrete block is moved by the pushing mechanism 9. The cutting mechanism 4 is used to cut the autoclaved aerated concrete block. The dust cover 51 and the cover plate 52 can initially isolate the dust diffusion and achieve the purpose of dust prevention. In addition, the dust generated by cutting is sealed by the dust cover 51. At this time, the dust suction hopper 83 at the top is connected to the vacuum cleaner 81 through the dust suction pipe 82 to absorb the dust sealed inside the dust cover 51, so that dust can be absorbed and stored at the same time as cutting.

[0029] The laser marking device 6, which emits light, projects a high-precision laser line onto the surface of the autoclaved aerated concrete (AAC) block to indicate the cutting path. The visible laser assists the operator in adjusting the block's position, ensuring the specimen's cutting dimensions meet requirements and improving cutting accuracy. It should be noted that, as... Figure 2 As shown, the dust cover 51 has a cutting groove that provides movement space for the band saw blade 41 in the cutting mechanism 4. Both the dust cover 51 and the cover plate 52 are made of transparent material, specifically transparent acrylic material, to facilitate observation of the cutting process.

[0030] like Figure 4 As shown, the cutting mechanism 4 includes a band saw blade 41 and two saw wheels 42 located at both ends of the band saw blade 41, driving its rotation. The two saw wheels 42 are rotatably fixed to the top of the workbench 1 and the frame 3, respectively. The saw wheels 42 are driven by a drive device. The drive device includes a first motor 46, and a drive pulley 45 is fixed to the output end of the first motor 46. The drive pulley 45 is connected to a driven pulley 43 via a synchronous belt 44. The driven pulley 43 is coaxially fixed to the saw wheels 42. The first motor 46 is electrically connected to a speed regulator 7.

[0031] In this embodiment, the first motor 46 is started to control the rotation of the drive pulley 45. Under the transmission action of the synchronous belt 44, the driven pulley 43 and the saw wheel 42 are driven to rotate synchronously. The band saw blade 41 circulates at high speed between the upper and lower saw wheels 42 to form a continuous cutting line. The speed regulator 7 is electrically connected to the first motor 46 through a wire to control the speed of the first motor 46, thereby adjusting the running speed of the band saw blade 41 and solving the problem of edge and corner damage during cutting.

[0032] like Figure 7As shown, the pushing mechanism 9 includes an L-shaped plate 91, which includes a horizontal plate and a vertical plate. A clamping plate 93 is slidably connected to the horizontal plate, and an mounting block 94 is fixed on the horizontal plate. A screw 95 is internally threaded onto the mounting block 94. One end of the screw 95 is rotatably connected to the clamping plate 93 and pushes the clamping plate 93 toward or away from the vertical plate by its own rotation. The bottom of the L-shaped plate 91 has a pushing device.

[0033] In this embodiment, the clamping plate 93 is used to position the autoclaved aerated concrete (AAC) blocks, and the pushing device drives the AAC blocks to move, which, in conjunction with the cutting mechanism 4, achieves the cutting purpose. By placing the AAC blocks on top of the L-shaped plate 91, the rotating screw 95 drives the clamping plate 93 to move, thereby clamping and fixing the AAC blocks. Multiple pre-drilled slots 92 on the L-shaped plate 91 provide clearance for multiple band saw blades 41, preventing interference between them.

[0034] like Figure 7 As shown, the system includes a fixed plate 98 fixed on the workbench 1, with a lead screw 96 rotatably connected to it. A lead screw sleeve adapted to the lead screw 96 is fixed to the bottom of an L-shaped plate 91. The lead screw 96 passes through the lead screw sleeve and is driven by a second motor 97. A sliding rod 99, parallel to the lead screw 96, is also fixed to the fixed plate 98 and is slidably connected to the L-shaped plate 91.

[0035] In this embodiment, the second motor 97 controls the lead screw 96 to rotate. The L-shaped plate 91 is driven to move by the cooperation between the lead screw 96 and the lead screw sleeve, which in turn drives the autoclaved aerated concrete block to move, thereby completing the cutting operation. The sliding rod 99 and the sleeve block can limit the movement trajectory of the L-shaped plate 91, so that the L-shaped plate 91 can move stably along the set path.

[0036] The specific operation process is as follows: the operator rotates the cover plate 52 upwards to open the dust cover 51, places the autoclaved aerated concrete block to be cut on the top of the L-shaped plate 91 of the pushing mechanism 9, rotates the screw 95 to push the clamping plate 93 to slide, clamping the block between the L-shaped plate 91 and the clamping plate 93, sets the speed of the first motor 46 through the speed regulator 7, and after starting the first motor 46, the active pulley 45 drives the driven pulley 43 through the synchronous belt 44, driving the saw wheel 42 to rotate, and the band saw blade 41 circulates at high speed between the upper and lower saw wheels to form a continuous cutting line. The second motor 97 is started to drive the lead screw 96 to rotate, and through the lead screw sleeve, the L-shaped plate 91 moves smoothly along the slide bar 99, so that the block passes through the band saw blade 41 at a uniform speed to complete the cutting. The dust generated by cutting is sealed by the dust cover 51, and the top dust suction hopper 83 is connected to the vacuum cleaner 81 through the dust suction pipe 82 to absorb and store the dust in real time.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
