Description

Technical Field

[0001] The present invention relates to the field of aerated concrete blocks, and specifically to a cutting device for aerated concrete blocks. Background Art

[0002] Aerated concrete is a lightweight concrete, which is characterized by a relatively low density and good heat insulation performance. It is made by adding a certain proportion of foaming agent or air-entraining agent to the concrete, so that a large number of tiny air bubbles are formed in the concrete, thereby reducing the density of the concrete. Cutting the concrete into blocks refers to the process of cutting the concrete material into block-shaped objects of specific sizes and shapes. This kind of cutting usually requires the use of professional concrete cutting equipment. When the existing cutting devices for aerated concrete blocks are in use, the relatively large aerated concrete blocks will be cut into small aerated concrete blocks that meet the usage size requirements according to the cutting needs. When the existing cutting devices are in use, most of the cutting machines use high-speed rotating saw blades for cutting. The high-speed centrifugal force of the saw blades often generates a large amount of dust during the cutting process. Therefore, most cutting devices will use a dust-proof cover to cover the entire cutting space. However, this method makes it necessary to wait for a certain period of time until the dust in the cutting space has completely settled before the dust-proof cover can be opened, which is rather troublesome to use. To solve this problem, a dust suction mechanism is installed on the dust-proof cover to absorb the dust inside the dust-proof cover. However, after each cutting is completed, the operator needs to open the dust-proof cover to take down the cut aerated concrete blocks, which is rather troublesome to operate and not suitable for continuous cutting work. Therefore, we propose a cutting device for aerated concrete blocks. Summary of the Invention

[0003] The purpose of the present invention is to provide a cutting device for aerated concrete blocks, including a workbench. A dust-proof cover is fixedly installed at the top of the workbench. Two groups of guiding components and two groups of baffle components are installed on the dust-proof cover. An installation groove is formed in the workbench. A conveyor belt one and a conveyor belt two are arranged in the installation groove. The outer sides of two groups of conveying rollers one are drivingly connected to the conveyor belt one, and the outer sides of two groups of conveying rollers two are drivingly connected to the conveyor belt two. The top ends of the conveyor belt one and the conveyor belt two are flush with the top end of the workbench. The guiding component includes an electric push rod one, which is fixedly installed on the outer wall of the dust-proof cover. The telescopic end of the electric push rod one is fixedly connected to a connecting frame. The connecting frame is fixedly connected to two moving plates. Both of the two moving plates slide through the inner side of the dust-proof cover. The two moving plates are respectively fixedly connected to a guiding strip. The top end of the moving plate slidably fits the top position of the inner wall of the dust-proof cover. The baffle assembly includes a fixing frame which is fixedly installed on the top end of the dust cover. A screw rod is rotatably connected to the fixing frame through a bearing. The screw rod is threadedly connected to the inner side of the convex block on the outer wall of the baffle. A servo motor is fixedly installed at the top end of the screw rod, and the servo motor is fixedly installed on the top end of the fixing frame. The baffle slides through the top of the dust cover.

[0004] Preferably, a set of sprocket one is respectively fixedly installed on the outer walls of the two sets of conveying rollers one. The two sets of sprocket one are both engaged with a chain one. A set of sprocket two is respectively fixedly installed on the outer walls of the two sets of conveying rollers two. The two sets of sprocket two are both engaged with a chain two. A set of sprocket three is respectively fixedly installed on the outer walls of a set of the conveying rollers one and a set of the conveying rollers two which are close to each other. The two sets of sprocket three are both engaged with a chain three. The workbench is fixedly connected to the mounting frame, and a set of speed reducers is fixedly installed on the mounting frame. The driving end of the speed reducer is fixedly connected to a set of conveying rollers one.

[0005] Preferably, a plurality of support legs are fixedly installed at the bottom of the workbench.

[0006] Preferably, an electric push rod two is fixedly installed on the top end of the workbench, and the telescopic end of the electric push rod two is fixedly connected to the auxiliary strip.

[0007] Preferably, a hydraulic cylinder is fixedly installed on the top end of the dust cover. The telescopic end of the hydraulic cylinder slides through the top of the dust cover and is fixedly connected to the lifting plate. The bottom end of the lifting plate is fixedly connected to the cutting blade.

[0008] Preferably, two guide rods are fixedly connected to the top end of the lifting plate, and the two guide rods both slide through the top of the dust cover.

[0009] Preferably, suction hoods are fixedly installed at the notches on both sides of the dust cover. A suction hopper is fixedly installed at the bottom of the workbench. The suction hopper and the two suction hoods are both connected to a suction pipe, and the suction pipe is connected to the suction end of an industrial vacuum cleaner.

[0010] Preferably, the exhaust port of the industrial vacuum cleaner is connected to one end of an exhaust pipe. The other end of the exhaust pipe penetrates through the top of the dust cover and is connected to a spring pipe. The pipe diameter of the exhaust pipe gradually becomes smaller from the end close to the industrial vacuum cleaner to the end close to the spring pipe. The end of the spring pipe away from the exhaust pipe is connected to a pipe. Four fixing blocks are fixedly installed on the outer wall of the pipe, and the four fixing blocks are all fixedly installed on the outer wall of the lifting plate. Two rows of bent pipes are connected to the pipe, and each group of bent pipes has a plurality of sets. The two rows of bent pipes are respectively aligned with both sides of the cutting blade.

The top end of the support plate one is slidably attached to the conveyor belt one, and the top end of the support plate two is slidably attached to the conveyor belt two.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the present invention is in use, through the transportation of conveyor belt 1 and conveyor belt 2, the aerated concrete blocks can be brought into the dust-proof cover, and the cut aerated concrete blocks are transported out of the inner cavity of the dust-proof cover. There is no need for the operator to open the dust-proof cover to take out the cut aerated concrete blocks. The operation is simple, and during the cutting process, no dust will overflow from the inlet and outlet ends of the aerated concrete blocks. Through the combined use of the guiding component and the baffle component, the rectangular through-hole formed between the guiding strips, the moving plate and the baffle at the same end matches the cutting surface of the aerated concrete block to be cut. Therefore, when the aerated concrete block passes through the rectangular through-hole formed between the guiding strips, the moving plate and the baffle at the same end, the aerated concrete block will block the rectangular through-hole formed between the guiding strips, the moving plate and the baffle at the same end, preventing dust from overflowing from the rectangular through-hole. Moreover, the size of the rectangular through-hole formed between the guiding strips, the moving plate and the baffle can be appropriately matched with the aerated concrete blocks with different cutting surface sizes within a certain range.

[0013] 2. When the present invention is in use, the industrial vacuum cleaner can absorb the debris dust generated by cutting, and the air discharged by the industrial vacuum cleaner can be used to cool the cutting blade, avoiding the cutting blade from getting too hot due to continuous cutting work. In addition, the air blown by the two rows of bent pipes towards the cutting blade can blow down the debris dust on the two sides of the cutting blade, playing a cleaning role.

Detailed implementation manner

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] Refer to Figure 1 - Figure 6 For a cutting device for aerated concrete blocks of the present invention, it includes a workbench 1. A dust-proof cover 2 is fixedly installed at the top end of the workbench 1. Two groups of guiding components 3 and two groups of baffle components 4 are installed on the dust-proof cover 2. An installation groove 5 is opened on the workbench 1. A first conveyor belt 6 and a second conveyor belt 7 are arranged in the installation groove 5. The first conveyor belt 6 is driven and connected to the outside of two groups of first conveyor rollers 8, and the second conveyor belt 7 is driven and connected to the outside of two groups of second conveyor rollers 9. The top ends of the first conveyor belt 6 and the second conveyor belt 7 are flush with the top end of the workbench 1. The guiding component 3 includes a first electric push rod 301. The first electric push rod 301 is fixedly installed on the outer wall of the dust-proof cover 2. The telescopic end of the first electric push rod 301 is fixedly connected to a connecting frame 302. The connecting frame 302 is fixedly connected to two groups of moving plates 303. Both groups of moving plates 303 slide through the inside of the dust-proof cover 2. The two groups of moving plates 303 are respectively fixedly connected to a guiding strip 304. The top end of the moving plate 303 slidably fits the top position of the inner wall of the dust-proof cover 2; the bottom of the moving plate 303 can slidably fit the top end of the workbench 1, the top end of the first conveyor belt 6, and the top end of the second conveyor belt 7. The bottom of the guiding strip 304 can slidably fit the top end of the workbench 1, the top end of the first conveyor belt 6, and the top end of the second conveyor belt 7.

[0018] The baffle assembly 4 includes a fixing frame 401 which is fixedly installed on the top end of the dust cover 2. A screw rod 402 is rotatably connected to the fixing frame 401 through a bearing. The screw rod 402 is threadedly connected to the inner side of the convex block on the outer wall of the baffle 403. A servo motor 404 is fixedly installed at the top end of the screw rod 402, and the servo motor 404 is fixedly installed on the top end of the fixing frame 401. The baffle 403 slidably penetrates through the top of the dust cover 2. It should be noted that both ends of the baffle 403 are slidably attached to the inner wall of the dust cover 2. It should be noted that the baffle 403 will slidably fit the outer sides of the two moving plates 303.

[0019] A set of sprockets one 10 are respectively fixedly installed on the outer walls of the two conveying rollers one 8. The two sprockets one 10 are both engaged with a chain one 11. A set of sprockets two 12 are respectively fixedly installed on the outer walls of the two conveying rollers two 9. The two sprockets two 12 are both engaged with a chain two 13. A set of sprockets three 14 are respectively fixedly installed on the outer walls of a set of the conveying rollers one 8 and a set of the conveying rollers two 9 which are close to each other. The two sprockets three 14 are both engaged with a chain three 15. The workbench 1 is fixedly connected to the mounting frame 16. A set of speed reducers 17 are fixedly installed on the mounting frame 16. The driving end of the speed reducer 17 is fixedly connected to a set of conveying rollers one 8. During use, when the speed reducer 17 is started and driven by the two sprockets one 10 and the chain one 11, the two conveying rollers one 8 will be driven to rotate in the same direction and at the same speed, and then the conveyor belt one 6 will be driven to perform the conveying work. When the conveying roller one 8 rotates and is driven by the two sprockets three 14 and the chain three 15, and the two sprockets two 12 and the chain two 13, the two conveying rollers two 9 will be driven to rotate in the same direction and at the same speed, and then the conveyor belt two 7 will be driven to perform the conveying work, and the conveying directions of the conveyor belt one 6 and the conveyor belt two 7 are the same. It should be noted that there is a gap between the conveyor belt one 6 and the conveyor belt two 7 to reserve space for the cutting blade 23 to move down to cut the aerated concrete block, to prevent the cutting blade 23 from moving down and cutting the conveyor belt one 6 and the conveyor belt two 7, and thus to prevent the cutting blade 23 from damaging the conveyor belt one 6 and the conveyor belt two 7.

[0020] A plurality of support legs 18 are fixedly installed at the bottom of the workbench 1. The workbench 1 can be strongly supported by the plurality of support legs 18.

[0021] An electric push rod two 19 is fixedly installed on the top end of the workbench 1. The telescopic end of the electric push rod two 19 is fixedly connected to the auxiliary strip 20. During use, when the electric push rod two 19 is started, the position of the auxiliary strip 20 can be adjusted so that the auxiliary strip 20 can be aligned and flush with the two guide strips 304 away from the industrial vacuum cleaner 28.

[0022] A hydraulic cylinder 21 is fixedly installed on the top end of the dust cover 2. The telescopic end of the hydraulic cylinder 21 slidably penetrates through the top of the dust cover 2 and is fixedly connected to a lifting plate 22. The bottom end of the lifting plate 22 is fixedly connected to a cutting blade 23. When in use, starting the hydraulic cylinder 21 can drive the lifting plate 22 to move downward. The downward movement of the lifting plate 22 will drive the cutting blade 23 to move downward, and the downward movement of the cutting blade 23 will complete the cutting of the aerated concrete block.

[0023] Two sets of guide rods 24 are fixedly connected to the top end of the lifting plate 22. Both sets of guide rods 24 slidably penetrate through the top of the dust cover 2. By providing two sets of guide rods 24, the lifting plate 22 can move up and down stably.

[0024] Suction hoods 25 are fixedly installed at the notches on both sides of the dust cover 2. A suction hopper 26 is fixedly installed at the bottom of the workbench 1. The suction hopper 26 and the two suction hoods 25 are both connected to a suction pipe 27, and the suction pipe 27 is connected to the suction end of an industrial vacuum cleaner 28. When in use, starting the industrial vacuum cleaner 28 and passing through the suction pipe 27 will cause the suction hopper 26 and the two suction hoods 25 to generate suction simultaneously, thereby absorbing the debris and dust generated during cutting. Moreover, the gap between the first conveyor belt 6 and the second conveyor belt 7 is directly above the suction hopper 26, so that the debris generated by cutting can fall into the suction hopper 26, and the debris and dust absorbed by the suction hopper 26 and the two suction hoods 25 will enter the industrial vacuum cleaner 28 through the suction pipe 27.

[0025] The exhaust port of the industrial vacuum cleaner 28 is connected to one end of an exhaust pipe 29. The other end of the exhaust pipe 29 penetrates through the top of the dust cover 2 and is connected to a spring tube 30. The pipe diameter of the exhaust pipe 29 gradually decreases from the end close to the industrial vacuum cleaner 28 to the end close to the spring tube 30. The end of the spring tube 30 away from the exhaust pipe 29 is connected to a pipe 31. Four fixing blocks 32 are fixedly installed on the outer wall of the pipe 31. All four fixing blocks 32 are fixedly installed on the outer wall of the lifting plate 22. Two rows of bent pipes 33 are connected to the pipe 31. Each group of bent pipes 33 has multiple sets. The two rows of bent pipes 33 are respectively aligned with both sides of the cutting blade 23. When the industrial vacuum cleaner 28 is working, the air absorbed by the industrial vacuum cleaner 28 will be discharged through the exhaust pipe 29. Since the pipe diameter of the exhaust pipe 29 gradually decreases from the end close to the industrial vacuum cleaner 28 to the end close to the spring tube 30, when the air flows in the exhaust pipe 29, the temperature of the air will be reduced. The air in the exhaust pipe 29 will enter the pipe 31 through the spring tube 30, and then blow to both sides of the cutting blade 23 from the two rows of bent pipes 33. Since the temperature of the blown air is relatively low, it can play a role in dissipating heat and cooling the cutting blade 23, avoiding the cutting blade 23 from getting too hot due to continuous cutting work. Moreover, the air blown from the two rows of bent pipes 33 to the cutting blade 23 can blow off the debris and dust on both sides of the cutting blade 23, playing a cleaning role.

[0026] On the groove wall of the installation groove 5, a first support plate 34 and a second support plate 35 are fixedly installed. The top end of the first support plate 34 is slidably attached to the first conveyor belt 6, and the top end of the second support plate 35 is slidably attached to the second conveyor belt 7. Since the top end of the first support plate 34 is slidably attached to the first conveyor belt 6, it can support the aerated concrete blocks conveyed at the top of the first conveyor belt 6, preventing the first conveyor belt 6 from being damaged due to the downward fall caused by the weight of the aerated concrete blocks. Since the top end of the second support plate 35 is slidably attached to the second conveyor belt 7, it can support the aerated concrete blocks conveyed at the top of the second conveyor belt 7, preventing the second conveyor belt 7 from being damaged due to the downward fall caused by the weight of the aerated concrete blocks.

[0027] The working principle of the present invention: Before cutting, start the two groups of first electric push rods 301 respectively. The first electric push rods 301 will drive the connecting frames 302 to move. The movement of the connecting frames 302 will drive the two groups of moving plates 303 to move. The movement of the two groups of moving plates 303 will drive the two groups of guide bars 304 to move, so that the distance between the guide bars 304 in the two groups of guide assemblies 3 meets the size of the aerated concrete blocks. Ensure that when the aerated concrete blocks are conveyed at the top of the first conveyor belt 6 and the second conveyor belt 7, the four guide bars 304 in the two groups of guide assemblies 3 are respectively attached to both sides of the aerated concrete blocks, effectively limiting the aerated concrete blocks during the conveying process; Starting the second electric push rod 19 can adjust the position of the auxiliary bar 20, so that the auxiliary bar 20 can be aligned and flush with the two guide bars 304 away from the industrial vacuum cleaner 28; Then start the servo motor 404, which will drive the screw rod 402 to rotate. The rotation of the screw rod 402 will drive the baffle 403 to move up and down. The distance between the bottom of the baffle 403 and the first conveyor belt 6 or the second conveyor belt 7 matches the height of the aerated concrete blocks to be cut; So that the rectangular through-hole formed between the guide bar 304, the moving plate 303 and the baffle 403 at the same end matches the cutting surface of the aerated concrete blocks to be cut. Furthermore, when the aerated concrete blocks pass through the rectangular through-hole formed between the guide bar 304, the moving plate 303 and the baffle 403 at the same end, the aerated concrete blocks will block the rectangular through-hole formed between the guide bar 304, the moving plate 303 and the baffle 403 at the same end, preventing dust from overflowing from the rectangular through-hole; When starting cutting, place the aerated concrete block to be cut on the top of conveyor belt 1 6, and one side of the aerated concrete block is attached to the auxiliary strip 20. Ensure that when the aerated concrete block is conveyed into the dust-proof cover 2, the four guiding strips 304 in the two guiding assemblies 3 are respectively attached to both sides of the aerated concrete block to effectively limit the aerated concrete block during the conveying process; then start the speed reducer 17. Under the driving action of the two sprockets 1 10 and the chain 1 11, it will drive the two conveying rollers 1 8 to rotate in the same direction and at the same speed, and then drive the conveyor belt 1 6 to carry out the conveying work. The conveying roller 1 8 rotates and under the driving action of the two sprockets 3 14 and the chain 3 15, as well as the driving action of the two sprockets 2 12 and the chain 2 13, it will drive the two conveying rollers 2 9 to rotate in the same direction and at the same speed, and then drive the conveyor belt 2 7 to carry out the conveying work, and the conveying directions of the conveyor belt 1 6 and the conveyor belt 2 7 are the same; the conveyor belt 1 6 will convey the aerated concrete block into the inner cavity of the dust-proof cover 2, and the conveyor belt 2 7 will convey the cut aerated concrete block out of the dust-proof cover 2; It should be noted that the dust-proof cover 2 can be made of reinforced glass with a certain thickness and transparency, which is convenient for observing the movement of the aerated concrete block in the inner cavity of the dust-proof cover 2. During the conveying process of the conveyor belt 1 6 and the conveyor belt 2 7, when the aerated concrete block moves to a suitable position, the speed reducer 17 stops working. Then start the hydraulic cylinder 21, which can drive the lifting plate 22 to move downward. The downward movement of the lifting plate 22 will drive the cutting blade 23 to move downward, and the downward movement of the cutting blade 23 will complete the cutting of the aerated concrete block; During the cutting process, start the industrial vacuum cleaner 28 and through the suction pipe 27, it will make the suction hopper 26 and the two suction covers 25 generate suction at the same time, so as to absorb the debris dust generated by cutting. And the gap between the conveyor belt 1 6 and the conveyor belt 2 7 is directly above the suction hopper 26, so that the debris generated by cutting can fall into the suction hopper 26, and the debris dust absorbed by the suction hopper 26 and the two suction covers 25 will enter the industrial vacuum cleaner 28 through the suction pipe 27; at the same time, the air absorbed by the industrial vacuum cleaner 28 will be discharged through the exhaust pipe 29. Since the pipe diameter of the exhaust pipe 29 gradually becomes smaller from the end close to the industrial vacuum cleaner 28 to the end close to the spring pipe 30, when the air flows in the exhaust pipe 29, the temperature of the air will be reduced. The air in the exhaust pipe 29 will enter the pipe 31 through the spring pipe 30, and then blow to both sides of the cutting blade 23 from the two rows of bent pipes 33. Since the temperature of the blown air is relatively low, it can play a role in dissipating heat and cooling the cutting blade 23, avoiding the cutting blade 23 from getting too hot due to continuous cutting work. And the air blown from the two rows of bent pipes 33 to the cutting blade 23 can blow down the debris dust on both sides of the cutting blade 23, playing a cleaning role.

[0028] It should be noted that when the device of the present invention is in use, an appropriate external power supply and controller are required. The external power supply provides power support for the operation of the first electric push rod 301, the second electric push rod 19, the reducer 17, the industrial vacuum cleaner 28, the hydraulic cylinder 21, etc. The operation of the first electric push rod 301, the second electric push rod 19, the reducer 17, the industrial vacuum cleaner 28, the hydraulic cylinder 21, etc. can be controlled through the external controller.

[0029] The above content further elaborates on the present invention in combination with specific embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention pertains, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, which should all be regarded as falling within the protection scope determined by the claims submitted for the present invention.
