Description

Technical Field

[0001] The present invention relates to the technical field of building boards, and more specifically, to a device for segmenting building boards. Background Art

[0002] Building boards are commonly used materials in the construction industry and are widely applied to structures such as walls, floors, and ceilings. Among them, fair-faced concrete is a building material favored for its natural surface effect. Its surface is usually smooth, and a smooth concrete surface is easier to clean and maintain, reducing the attachment of dirt and stains. This not only helps to maintain its aesthetics but also extends its service life and reduces maintenance costs.

[0003] In the prior art, the cutting of concrete slabs is an important link in construction, which can significantly improve construction efficiency and accuracy. However, during the cutting process of concrete slabs, dust and debris are inevitably generated. These dust and debris not only increase the subsequent cleaning difficulty but also adhere to the conveying mechanism for conveying concrete slabs, resulting in the concrete slabs being supported by the debris and unable to fully contact the conveying surface of the conveying mechanism, affecting the contact surface between the slabs and the conveying mechanism, and thus causing the concrete slabs to slide under the interference of the debris during conveyance, affecting the flatness of the cut segments of the concrete slabs.

[0004] Therefore, those skilled in the art have provided a device for segmenting building boards to solve the problems raised in the above background art. Summary of the Invention

Detailed implementation manners

[0027] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described: Embodiment

[0028] Referring to Figure 1 - Figure 10 In a device for segmenting building boards disclosed by the present invention, there is a base 1. A trapezoidal groove 6 that is wider at the top and narrower at the bottom is formed along the length direction on the top of the base 1. A dust collection groove 7 is formed downward at the bottom of the trapezoidal groove 6. Suction cavities 8 are formed on both the front and rear sides of the dust collection groove 7 inside the base 1. The suction cavities 8 are communicated with the dust collection groove 7 through air inlet grooves 9; The gantry 2 is arranged above the dust collecting tank 7 and fixedly connected to the base 1. A linear actuator 10 is fixedly connected to the top of the gantry 2, and the output shaft of the linear actuator 10 penetrates downward through the gantry 2; The cutter 3 is arranged inside the gantry 2, and the top of the cutter 3 is fixedly connected to the output shaft of the linear actuator 10; The feeding mechanism 4 is symmetrically arranged in the front and back in the trapezoidal groove 6. Two groups of feeding mechanisms 4 are arranged at intervals along the length direction of the trapezoidal groove 6, and are used for conveying building boards; The dust removal mechanism 5 includes a negative pressure pipe fitting 51, an air pump 52 and a three-way pipe 53. The air pump 52 is installed at the bottom of the base 1. The suction end of the air pump 52 is fixedly connected to the three-way pipe 53. The two branch pipes of the three-way pipe 53 are respectively inserted into the two suction cavities 8 and are connected with the negative pressure pipe fitting 51 at the suction port; The negative pressure pipe fitting 51 is mainly composed of a sleeve 511, a partition plate 512 and a piston 513. The middle of the sleeve 511 is connected with the partition plate 512. The partition plate 512 divides the inside of the sleeve 511 into two cavities, an upper cavity 11 and a lower cavity 12. A round hole 13 for communicating the upper cavity 11 and the lower cavity 12 is opened on the side of the partition plate 512 away from the air inlet groove 9. The upper cavity 11 is communicated with the branch pipe of the three-way pipe 53. A plurality of suction holes 14 are opened at the top of the upper cavity 11, and a pressure valve 15 is fixedly connected in the suction holes 14. A piston 513 is slidably connected in the lower cavity 12. A support spring 16 is fixedly connected between the side of the piston 513 away from the air inlet groove 9 and the side wall of the lower cavity 12. An anti-blowing groove 17 for blowing back the air inlet groove 9 is opened on the side of the lower cavity 12 where the piston 513 is away from the support spring 16.

[0029] In this embodiment, observe Figure 1 It can be found that by opening a trapezoidal groove 6 with a wider top and a narrower bottom along the length direction at the top of the base 1, two groups of feeding mechanisms 4 are symmetrically arranged in the front and back in the trapezoidal groove 6, and each group of feeding mechanisms 4 is arranged at intervals along the length direction of the trapezoidal groove 6, which can be used to convey building boards. Subsequently, a gantry 2 is connected to the top of the base 1, a linear actuator 10 is connected to the top of the gantry 2, and the output shaft of the linear actuator 10 passes through the gantry 2 and is connected to the cutter 3 inside the gantry 2. When the building board is segmented, the cutter 3 can be lowered by the linear actuator 10 to cut the building board. At the same time, during the cutting process, in order to prevent the building board from running off, a conventional fixture (not shown in the figure) will be used to fix the building board during cutting to improve the cutting accuracy.

[0030] During the cutting process of the concrete slab, dust and debris will inevitably be generated. These dust and debris will not only increase the difficulty of subsequent cleaning, but also adhere to the conveying mechanism for transporting the concrete slabs, resulting in the concrete slabs being supported by the debris and unable to fully contact the conveying surface of the conveying mechanism, affecting the contact surface between the slabs and the conveying mechanism. As a result, when the concrete slabs are transported, they will slide due to the interference of the debris. When the fixture fixes the building slabs, the building slabs will be in a slightly inclined state, affecting the flatness of the cut sections of the concrete slabs.

[0031] Therefore, by combining Figure 2 and Figure 3 it can be found that Figure 2 is a three-dimensional structural schematic diagram of the position of the suction chamber in the front view of the building slab segmentation processing device. Figure 3 Figure 3 is the three-dimensional structural schematic diagram of the dust collection tank 7 in the top view of the building slab segmentation processing device. From it, we can find that a dust collection tank 7 is opened downward at the bottom of the trapezoidal groove 6, and suction chambers 8 are opened on both the front and rear sides of the dust collection tank 7 in the base 1. The suction chambers 8 are connected to the dust collection tank 7 through air inlet grooves 9. Subsequently, an air pump 52 is installed at the bottom of the base 1. The suction end of the air pump 52 is fixedly connected to a tee pipe 53. The two branch pipes of the tee pipe 53 are respectively inserted into the two suction chambers 8 and are connected with negative pressure pipe fittings 51 at the suction ports. The air pump 52 can be operated to make the negative pressure pipe fittings 51 suck air in the suction chambers 8, so that negative pressure is generated in the suction chambers 8. At this time, negative pressure will be generated at the air inlet grooves 9 connecting the suction chambers 8 and the dust collection tank 7, which is used to adsorb the dust and debris generated when the cutter 3 cuts the concrete slabs, preventing the dust and debris from floating around, effectively reducing the environmental cleaning difficulty after the building slab segmentation work, and at the same time avoiding the dust from falling on the conveying plane of the feeding mechanism 4 and affecting the contact between the building slab and the feeding mechanism 4, thus effectively ensuring that the building slab will not shift during feeding, and further improving the segmentation accuracy of the building slab.

[0032] And in Figure 3 it can be seen that a filter screen is installed at the position of the air inlet groove 9, which can be used to prevent dust and debris from entering the suction chamber 8 and flowing into the air pump 52 along the negative pressure pipe fittings 51, affecting the service life of the air pump 52. However, as the operation time of the building slab segmentation processing device increases, the mesh holes of the filter screen will eventually become blocked, affecting the air intake of the suction chamber 8, resulting in a decrease in the negative pressure at the air inlet groove 9, affecting the adsorption of dust, and thus causing the effect of the dust removal mechanism 5 to deteriorate.

[0033] Therefore, by combining Figure 3 、 4 and Figure 5 it can be found that Figure 4 is the structural schematic diagram of the dust removal mechanism 5 in the building slab segmentation processing device. Figure 5 Then it is Figure 4Schematic diagram of the rear elevation perspective structure of the negative pressure pipe fitting 51 at the front middle side. At this time, it can be found that the negative pressure pipe fitting 51 is mainly composed of a sleeve 511, a partition plate 512 and a piston 513. The middle part of the sleeve 511 is connected with a partition plate 512. The partition plate 512 divides the inside of the sleeve 511 into two cavities, an upper cavity 11 and a lower cavity 12. A round hole 13 for communicating the upper cavity 11 and the lower cavity 12 is opened on the side of the partition plate 512 away from the air inlet groove 9, which can keep the upper cavity 11 and the lower cavity 12 in a communicating state.

[0034] Subsequently, the upper cavity 11 is connected to the branch pipe of the three-way pipe 53. A plurality of air suction holes 14 are opened at the top of the upper cavity 11. A pressure valve 15 is fixedly connected in the air suction holes 14. A piston 513 is slidably connected in the lower cavity 12. A support spring 16 is fixedly connected between the side of the piston 513 away from the air inlet groove 9 and the side wall of the lower cavity 12. An air blowing groove 17 for blowing back the air inlet groove 9 is opened on the side of the lower cavity 12 away from the support spring 16 of the piston 513.

[0035] At this time, when the air pump 52 operates, a negative pressure will be generated in the upper cavity 11. Due to the setting of the pressure valve 15 at the position of the air suction holes 14, when the negative pressure is less than the threshold value of the pressure valve 15, the upper cavity 11 cannot suck air. At this time, the pressure reduction in the upper cavity 11 will cause the pressure in the lower cavity 12 to decrease synchronously through the communication of the round hole 13, so that the piston 513 in the lower cavity 12 is pushed to approach the round hole 13 under the action of the atmospheric pressure, and the space in the area of the air blowing groove 17 in the lower cavity 12 gradually increases. When the piston 513 approaches the round hole 13, the piston 513 will continuously compress the support spring 16, so that the elastic force of the support spring 16 continuously increases.

[0036] At this time, it can be found that the pressure required to open the pressure valve 15 is F1, the elastic force of the support spring 16 is F2, and the upper cavity 11 and the lower cavity 12 are connected, so the pressures are close to the same, so they are both P1, and the unchanged external atmospheric pressure is P. According to the above scenario, it can be found that the greater the pressure difference between P2 and P1, the greater the thrust exerted by the atmospheric pressure on the piston 513, and the greater the elastic force F2 exerted by the support spring 16 on the piston 513 after being compressed. Until F2 is the same as F1 of the pressure valve, as the negative pressure in the upper cavity 11 increases, the pressure valve 15 will open. At this time, a negative pressure will be generated in the air suction cavity 8, so that the air inlet groove 9 generates suction force to suck the dust and debris generated during the cutting of the building board into the dust collection groove 7.

[0037] Finally, after the building board is segmented, the building board segmentation processing device stops. With the shutdown of the air pump 52, the negative pressure in the upper cavity 11 disappears. During the process of the disappearance of the negative pressure, the pressure difference between P1 and P2 also disappears. At this time, the air pressure thrust applied to the piston 513 disappears. Subsequently, the piston 513 that loses the pressure applied by the air pressure will quickly reset under the elastic force of the support spring 16, so that the air in the lower cavity 12 is quickly squeezed, and the air in the lower cavity 12 is blown out through the back-blowing groove 17, so that the high-speed flowing air is back-blown into the filter screen installed in the air inlet groove 9, which is used to blow off the debris blocking the mesh holes, effectively preventing the mesh holes of the filter screen from being blocked, improving the service life of the filter screen, greatly extending the service time of the building board segmentation processing device, reducing the maintenance frequency of the building board segmentation processing device, and thus reducing the maintenance cost of the building board segmentation processing device.

[0038] And it can also be found that Figure 5 a limiting block 23 is fixedly connected to the inner wall of the lower cavity 12 at a position where the back-blowing groove 17 is close to the piston 513, which can be used to limit the stroke of the piston 513, and can prevent the piston 513 from sliding into the position of the back-blowing groove 17, resulting in the air in the lower cavity 12 being sucked away by the negative pressure in the upper cavity 11. At this time, the air will enter the lower cavity 12 through the gap between the back-blowing groove 17 and the piston 513, which will affect the increase of the negative pressure in the upper cavity 11 and thus affect the operation stability of the dust removal mechanism 5.

[0039] Since the setting of the limiting block 23 will inevitably collide with the piston 513 when the piston 513 rebounds quickly, in order to reduce the damage caused by the collision and at the same time weaken the noise generated by the collision, a buffer gasket 24 is fixedly connected to the side of the limiting block 23 close to the piston 513, which can effectively protect the piston 513 and the limiting block 23.

[0040] In a further preferred embodiment of the present invention, as Figure 1 , Figure 2 and Figure 6 - Figure 8 shown, the feeding mechanism 4 includes a support plate 41, a conveying wheel 42 and a boosting unit 43. The bottom of the support plate 41 is fixedly connected to the inclined side wall of the trapezoidal groove 6. A conveying wheel 42 for conveying building boards is arranged on the top of the support plate 41. A through groove 18 communicating with the suction cavity 8 is opened on the top of the support plate 41 near the suction cavity 8. A boosting unit 43 connected to the conveying wheel 42 is arranged in the through groove 18; The boosting unit 43 includes a rotating shaft 431 and blades 432. A track groove 19 is opened on the side wall of the through groove 18. A rotating shaft 431 is arranged in the track groove 19. The rotating shaft 431 is fixedly connected to the conveying wheel 42 through a connecting rod. A plurality of blades 432 are annularly arranged on the outer wall of the rotating shaft 431. The blades 432 located on the side of the rotating shaft 431 close to the through groove 18 extend into the through groove 18; The number of the through grooves 18 on the same side as the suction holes 14 formed in the sleeve 511 is the same, and a plurality of suction holes 14 are arranged directly below a plurality of through grooves 18 in a one-to-one correspondence.

[0041] In this embodiment, since the concrete slab is usually heavy, the frictional force is large when the concrete slab moves on the base 1, which affects the feeding of the concrete slab. Therefore, combined with Figure 1 and Figure 8 it can be found that Figure 8 is a schematic structural diagram of the feeding mechanism 4. By connecting a plurality of support plates 41 at intervals in the trapezoidal groove 6, and a conveying wheel 42 for conveying building plates is arranged on the top of the support plate 41, multi-point support can be provided for the building plates, reducing the pressure received by each conveying wheel 42. While ensuring the stability of the conveying of the building plates, it can be used to reduce the feeding difficulty of the concrete slab.

[0042] Subsequently, combined with Figure 6 and Figure 7 it can be found that Figure 6 is a sectional perspective structural diagram of the left side view of the feeding mechanism 4 at the position of the through groove 18. Figure 7 is a sectional perspective structural diagram of the front side view of the feeding mechanism 4 at the position of the through groove 18. At this time, it can be found that a track groove 19 is formed in the side wall of the through groove 18, a rotating shaft 431 is arranged in the track groove 19, the rotating shaft 431 is fixedly connected with the conveying wheel 42 through a connecting rod, and a plurality of blades 432 are annularly arranged on the outer wall of the rotating shaft 431. The blades 432 located on the side of the rotating shaft 431 close to the through groove 18 extend into the through groove 18.

[0043] At this time, when negative pressure is generated in the suction chamber 8, suction will also be generated at the corresponding position of the through groove 18, causing the air in the through groove 18 to flow. When the air flows downward in the through groove 18, a thrust will be applied to the blade 432 extending into the through groove 18, so that the rotating shaft 431 has a tendency to rotate. Therefore, the conveying wheel 42 fixedly connected to the rotating shaft 431 also has a tendency to rotate. And the building plate to be segmented is relatively large, so it will contact a plurality of conveying wheels 42. At this time, the conveying wheels 42 in contact with the building plate will simultaneously apply a forward force to the building plate, which can further reduce the thrust required when the building plate is fed, and further reduce the feeding difficulty of the building plate.

[0044] Since the negative pressure is generated at the position of the suction hole 14, the negative pressure in the through groove 18 farther away from the suction hole 14 will be lower, resulting in a reduction in the thrust applied by the air to the blade 432, which will affect the effect of the feeding mechanism 4 assisting in feeding the building plate. Therefore, observing Figure 2It can be found that by making the number of air suction holes 14 formed in the sleeve 511 the same as the number of through grooves 18 on the same side of the trapezoidal groove 6, and arranging the plurality of air suction holes 14 directly below the plurality of through grooves 18 in one-to-one correspondence, the suction force in the through grooves 18 can be effectively guaranteed, thereby ensuring the feeding assistance effect of the feeding mechanism 4 on the building board.

[0045] In a further preferred embodiment of the present invention, as Figure 9 and Figure 10 shown, the top of the support plate 41 is higher than the top of the base 1, so that a space for avoiding the cutting knife is left between the bottom of the building board and the base 1.

[0046] In this embodiment, since the cutting device 3 needs to segment the building board and the cutting knife needs to completely penetrate the building board, when the building board contacts the base 1, the cutting knife will cut the base 1 when penetrating the building board, resulting in damage to the base 1.

[0047] Therefore, in combination with Figure 9 and Figure 10 it can be found that Figure 9 is a schematic diagram of the state where the cutting device 3 is cutting the building board, and Figure 10 is Figure 9 the front view of the state. At this time, it can be found in Figure 10 that the top of the support plate 41 is higher than the top of the base 1, so that a space for avoiding the cutting knife is left between the bottom of the building board and the base 1. At the same time, a gap for avoiding the cutting knife will also be left between the spaced support plates 41. Therefore, when the cutting knife penetrates the building board as Figure 9 shown, the cutting knife will not contact the base 1 and the support plate 41.

[0048] In a further preferred embodiment of the present invention, as Figure 8 - Figure 10 shown, a chute 20 is formed downward at the top of the support plate 41. A connecting seat 21 is slidably connected in the chute 20. A compression spring 22 is fixedly connected between the bottom of the connecting seat 21 and the chute 20. The top of the connecting seat 21 is rotatably connected to the conveying wheel 42; The left side of the cutting device 3 is rotatably connected with a connecting plate 25, and a torsion spring 26 is arranged at the connection. The side of the connecting plate 25 away from the cutting device 3 is rotatably connected with a housing 27. A feeding wheel 28 is rotatably connected in the housing 27 through a one-way bearing.

[0049] In this embodiment, since the through groove 18 of the feeding mechanism 4 is communicated with the suction cavity 8, when the negative pressure pipe fitting 51 sucks air, the negative pressure in the suction cavity 8 will be weakened due to the intake of air through the through groove 18, resulting in a weakened suction force at the intake groove 9, which will affect the collection effect of dust and debris.

[0050] Therefore, inFigure 8 It can be found that a chute 20 is opened downward at the top of the support plate 41. A connecting seat 21 is slidably connected in the chute 20. A compression spring 22 is fixedly connected between the bottom of the connecting seat 21 and the chute 20. The top of the connecting seat 21 is rotatably connected to the conveying wheel 42. Then look at Figure 10 It can be found that a connecting plate 25 is rotatably connected to the left side of the cutter 3, and a torsion spring 26 is arranged at the connection.

[0051] At this time, when the cutter 3 approaches the building board, the connecting plate 25 will slide on the surface of the building board, increasing the opening angle between the connecting plate 25 and the cutter 3, so that the torsion spring 26 twists to apply a restoring elastic force to the connecting plate 25. At this time, the building board will be pressed down by the connecting plate 25 to enhance the extrusion on the conveying wheel 42. Under the dual pressure of the weight of the building board and the connecting plate 25, the conveying wheel 42 will squeeze the connecting seat 21 to slide down in the chute 20, so that the building board is as Figure 10 shown in the state and fits with the end face of the support plate 41, thus blocking the through groove 18.

[0052] Since the surface of fair-faced concrete is usually smooth, compared with ordinary concrete, when the surface of fair-faced concrete fits with the end face of the support plate 41, the air passage gap can be greatly reduced, so that the air intake volume of the through groove 18 is greatly reduced, enabling the cutter 3 to maintain the maximum suction at the air intake groove 9 when cutting the building board, effectively sucking the generated chips and dust into the dust collection groove 7, and further ensuring the stable use of the dust removal mechanism 5.

[0053] Since the building board blocks the through groove 18, when a negative pressure is generated in the through groove 18, an adsorption and positioning effect will be applied to the building board. At the same time, combined with the friction between the building board and the top of the support plate 41 and the pressure applied by the connecting plate 25 to the building board, the positioning effect during the cutting of the building board can be effectively improved, further ensuring the segmentation accuracy of the building board.

[0054] After the cutting is completed, as the cutter 3 moves upward, the connecting plate 25 gradually moves away from the building board, and the pressure on the building board disappears. At this time, the weight of the building board cannot stably press down the conveying wheel 42. Therefore, under the push of the compression spring 22, the building board will separate from the support plate 41, reopening the through groove 18 and enabling the boosting unit 43 to resume its boosting effect.

[0055] Since the building board is in rolling contact with the conveying wheel 42, the building board will be pushed to move when the connecting plate 25 slides on the building board. So Figure 10It can be found that a housing 27 is rotatably connected to the side of the connecting plate 25 away from the cutter 3. A feeding wheel 28 is rotatably connected to the housing 27 through a one-way bearing. At this time, when the cutter 3 moves downward, the connecting plate 25 is in rolling contact with the building board through the feeding wheel 28, avoiding the connecting plate 25 from pushing the building board to move and ensuring the segmentation accuracy. When the cutter 3 moves upward, the feeding wheel 28 will move reversely under the pulling of the connecting plate 25. However, due to the one-way rotation limitation of the one-way bearing, the feeding wheel 28 cannot rotate. Therefore, when the feeding wheel 28 moves reversely, a forward force will be applied to the building board. This forward force combined with the force applied by the conveying wheel 42 on the building board can push the building board forward to achieve an automatic feeding effect, which can further reduce the feeding difficulty of the building board, thereby increasing the segmentation difficulty of the building board and significantly improving the segmentation efficiency of the building board.
