Description

Technical Field

[0001] The present invention belongs to the technical field of cement product processing, and specifically relates to a flip - type cutting device for cement board processing. Background Technique

[0002] Cement fiber board is a kind of cement product. It uses cement as the base material and incorporates reinforcing materials such as mineral fibers. It is made through processes such as pulping, forming, and curing, and has characteristics such as fire resistance, waterproofness, and weather resistance. If the width of the processed cement fiber board exceeds the requirement, the size needs to be adjusted through a cutting device. When cutting, an electric circular saw or a tungsten carbide alloy straight - tooth saw blade is commonly used, and a dust removal device is used to reduce dust pollution; for thick plates or high - density plates, a special cutting machine is required to ensure a smooth cut. The edges of the cut plates can be trimmed with a file or an angle grinder to meet the installation requirements.

[0003] Some cutting devices have a large placement table for placing long and wide cement fiber boards. Multiple support blocks are arranged on the top of the placement table. These support blocks are arranged and designed in a "chocolate" shape, increasing the friction between the placement platform and the cement fiber board, effectively preventing the slight displacement of the board during cutting due to the friction and vibration of the saw blade, and ensuring the cutting accuracy and stability; however, during the descent of the cutting saw blade, the depth of the saw blade descent needs to exceed the bottom of the cement fiber board for complete cutting, which easily causes the saw blade to collide with the support blocks and result in damage. Summary of the Invention

[0004] To solve the problems raised in the above - mentioned background technique, the present invention provides a flip - type cutting device for cement board processing.

[0005] To achieve the above - mentioned purpose, the present invention provides the following technical solution: A flip - type cutting device for cement board processing, including a machine body, a table body, a saw blade body, and a lifting seat, and further including: Hoods arranged on both sides of the saw blade body. Electromagnets are bolted inside the hoods. A number of vertical grooves are penetrated through the surface of the table body. An outer cylinder is arranged inside the vertical grooves, and the outer cylinder is bolted to the bottom surface of the table body; A support block body slidably connected to the upper part inside the outer cylinder. A cylinder cover is also bolted to one side of the outer cylinder. A sealing gasket is arranged between the cylinder cover and the outer cylinder. The support block body is slidably connected to the inner wall of the sealing gasket. A bottom cover is bolted to the bottom of the support block body. A compression spring is fixed to the lower part inside the outer cylinder, and the top end of the compression spring is located inside the bottom cover; A top cover bolted to the top of the support block body. A frame body is arranged inside the top cover. A permanent magnet is arranged inside the frame body. A one - way speed - reducing mechanism is also arranged inside the outer cylinder. A flip - over mechanism is arranged on the top and inside of the machine body.

[0006] Preferably, the one-way retardation mechanism includes a movable rod, a cylinder body and an oil seal. The cylinder body is bolted inside the outer cylinder, and a compression spring is sleeved outside the cylinder body. The oil seal is fixed to the top of the cylinder body. The top end of the movable rod is bolted to the inner wall of the bottom cover. The movable rod is slidably connected to the inner wall of the oil seal. A piston plate is bolted to the bottom end of the movable rod, and the piston plate is slidably connected to the inside of the cylinder body. A plurality of arc-shaped grooves are formed on the surface of the piston plate. A plurality of connecting blocks are also bolted to the top of the piston plate. A rotating column is rotatably connected to the surface of the connecting block. A one-way cover is welded to the surface of the rotating column. A limiting rod is also bolted to one side above the surface of the connecting block. A through hole is formed in the surface of the one-way cover.

[0007] Preferably, an oil injection port is also communicated and arranged on the other side of the top of the cylinder body.

[0008] Preferably, the one-way cover is integrally designed in a fan shape and has an area larger than the cross-sectional area of the inner wall of the arc-shaped groove.

[0009] Preferably, the flipping mechanism includes a hydraulic cylinder, a lifting plate and a rack. The number of hydraulic cylinders is multiple groups and they are bolted inside the machine body. The lifting plate is bolted to the output shaft of the hydraulic cylinder. The rack is bolted to the top of the lifting plate. Vertical plates are bolted to the top of the machine body and on both sides of the table body. Connecting plates are bolted to both sides of the table body. A connecting column is welded to the surface of the connecting plate, and the connecting column is rotatably connected to the surface of the vertical plate. A transmission gear meshing with the rack is bolted to the surface of the connecting column. A through groove is formed in the top of the machine body.

[0010] Preferably, a sliding rod is also bolted inside the machine body. A sliding sleeve is bolted to one side of the rack, and the sliding sleeve is slidably connected to the surface of the sliding rod.

[0011] Preferably, a limiting plate is also bolted above the surface of the sliding rod.

[0012] Preferably, a top groove is formed in the top of the top cover.

[0013] Preferably, a glass cover is also fixed to the top of the top cover, and the glass cover is adhesively fixed inside the top groove.

[0014] Preferably, the permanent magnet is a neodymium iron boron strong magnet.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By turning on the electromagnet, a magnetic field is formed on both sides of the saw blade to cooperate with the permanent magnets inside the support block and the top cover, causing the support block to move downward under the repulsive force, making the support block close to the saw blade descend and avoid it. At the same time, the support block far from the saw blade can still support the cement fiber board under the upward acting force of the compression spring. While ensuring the support effect, it can also prevent collisions between the saw blade and the support block or the top cover, achieving the protection of the saw blade.

[0016] 2. When the support block descends, it drives the bottom cover, the movable rod and the piston plate to descend, making the one-way cover in an open state. When the support block descends, it is subject to less hydraulic resistance, which is conducive to the rapid descent of the support block. At the same time, during the ascending process, the one-way cover closes, making the resistance received by the support block during the rebound ascending process larger, preventing the support block from rebounding too fast and causing damage to the bottom of the cement fiber board.

[0017] 3. By turning on the hydraulic cylinder to make its output shaft extend to drive the rack to rise, combined with the cooperation of the transmission gear and the connecting column, the table body is driven to flip so that its top faces downward, in order to disassemble the outer cylinder installed inside, eliminating the need for workers to enter the interior of the machine for disassembly, bringing convenience to the maintenance operation.

Detailed implementation manners

[0020] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0021] As Figures 1 to 19As shown in the figure, the present invention provides a flip - type cutting device for cement board processing, including a machine body 1, a table body 2, a saw blade body 7 and a lifting seat 6. The table body 2 is the placement table of the cutting machine. Horizontal moving seats 3 are arranged on both sides of the machine body 1, and slide rails are also arranged on both sides of the machine body 1. The horizontal moving seats 3 can move along the surface of the slide rails (how to drive the horizontal moving seats 3 to move is prior art). A cross beam 4 is fixed above the horizontal moving seats 3. A transverse moving seat 5 is arranged on one side of the cross beam 4, and the transverse moving seat 5 can move horizontally along the direction of the cross beam 4. The lifting seat 6 is arranged on one side of the transverse moving seat 5, and the saw blade body 7 is arranged below the lifting seat 6. In actual use, a motor (not shown in the figure) for driving the saw blade body 7 is arranged inside the lifting seat 6. The lifting seat 6 is lifted and lowered by hydraulic drive. This device is an innovation based on the fiber board cutting machine in the prior art. The horizontal moving seats 3, cross beam 4, transverse moving seat 5, lifting seat 6, saw blade body 7, etc. in the device are all prior art, and their specific working methods and structures will not be described in detail. Covers 8 are arranged on both sides of the saw blade body 7. One group of covers 8 is fixed to the lifting seat 6 through a connecting rod, and the other group of covers 8 is directly bolted to the bottom of the lifting seat 6. An electromagnet 9 is bolted inside the cover 8. The material of the cover 8 is aluminum alloy. As a non - magnetic material, μr≈1 for aluminum alloy, it cannot guide magnetic induction lines through high magnetic permeability like ferromagnetic materials such as silicon steel, so it cannot completely shield the magnetic field. However, its high electrical conductivity will generate an eddy current effect in an alternating magnetic field, forming a reverse magnetic field, which can have a certain inhibitory effect on the high - frequency alternating magnetic field (skin effect), but has limited shielding effect on direct current or low - frequency magnetic fields. The opening at the bottom of the cover 8 forms a "diversion channel" for magnetic induction lines, so that the main magnetic field is released downward, reducing lateral diffusion. Therefore, the magnetic field generated by the electromagnet 9 is mainly downward, preventing it from spreading to the surrounding area. A number of vertical grooves 22 are penetrated through the surface of the table body 2. The vertical grooves 22 are distributed in rows. An outer cylinder 10 is arranged inside the vertical grooves 22, and the outer cylinder 10 is bolted to the bottom surface of the table body 2. Fixed ears are welded below both sides of the outer cylinder 10 for passing through bolts for fixation (the bolt - fixing method is prior art and not shown in the figure). A support block 12 is slidably connected above the inside of the outer cylinder 10. A cylinder cover 11 is also bolted to one side of the outer cylinder 10. A sealing gasket 13 is arranged between the cylinder cover 11 and the outer cylinder 10. The sealing gasket 13 is designed in a square shape. The cylinder cover 11 and the outer cylinder 10 are fixed to each other and can also be disassembled. The cylinder cover 11 fixes the sealing gasket 13 inside the outer cylinder 10. The support block 12 is slidably connected to the inner wall of the sealing gasket 13, increasing the sealing performance of the support block 12 during the sliding process. A bottom cover 14 is bolted to the bottom of the support block 12. A compression spring 15 is fixed below the inside of the outer cylinder 10, and the top end of the compression spring 15 is located inside the bottom cover 14. A top cover 16 is bolted to the top of the support block 12. A frame 19 is arranged inside the top cover 16, and a permanent magnet 18 is arranged inside the frame 19. The permanent magnet 18 is a neodymium - iron - boron strong magnet, and the material of the frame 19 is aluminum alloy,The top cover 16 and the support block 12 are made of stainless steel. The frame 19 can concentrate the magnetic field generated by the permanent magnet 18 upward. A top groove is opened at the top of the top cover 16 for the magnetic field of the permanent magnet 18 to pass through. A glass cover 17 is also fixed to the top of the top cover 16. The glass cover 17 is made of tempered glass and is adhesively fixed inside the top groove. The magnetic field can easily pass through the glass cover 17 at the top of the top cover 16, and at the same time, the glass cover 17 can also be flush with the top of the top cover 16. The glass cover 17 and the top of the top cover 16 jointly contact the bottom of the cement fiber board to provide support. A one-way speed reduction mechanism 20 is also provided inside the outer cylinder 10, and a flipping mechanism 21 is provided at the top and inside of the machine body 1.,

[0022] The one-way speed reduction mechanism 20 includes a movable rod 201, a cylinder body 202 and an oil seal 203. The cylinder body 202 is bolted inside the outer cylinder 10, and the compression spring 15 is sleeved outside the cylinder body 202. The oil seal 203 is fixed to the top of the cylinder body 202. The top end of the movable rod 201 is bolted to the inner wall of the bottom cover 14, so that when the bottom cover 14 moves up or down, it can drive the movable rod 201 to move together. The movable rod 201 is slidably connected to the inner wall of the oil seal 203. A piston plate 204 is bolted to the bottom end of the movable rod 201, and the piston plate 204 is slidably connected to the inside of the cylinder body 202. A number of arc-shaped grooves 2011 are opened on the surface of the piston plate 204. A number of connecting blocks 205 are also bolted to the top of the piston plate 204. A rotating column 206 is rotatably connected to the surface of the connecting block 205. A one-way cover 208 is welded to the surface of the rotating column 206, and the one-way cover 208 is designed in an arc shape as a whole. A limiting rod 207 is bolted to one side above the surface of the connecting block 205. A through hole 209 is opened on the surface of the one-way cover 208. Another side of the top of the cylinder body 202 is also communicated with an oil injection port 2010. The one-way cover 208 is designed in a fan shape as a whole and has an area larger than the cross-sectional area of the inner wall of the arc-shaped groove 2011. Hydraulic oil is filled into the inside of the cylinder body 202 through the oil injection port 2010, so that there is hydraulic oil on both the upper and lower sides of the piston plate 204 inside the cylinder body 202.,

[0023] When working, the compression spring 15 applies an upward acting force to the bottom cover 14, causing the support block 12 to move upward until the bottom cover 14 contacts the upper part of the inner wall of the outer cylinder 10. At the same time, the support block 12 is located above the inside of the frustum 2. Place the cement fiber board to be cut inside the frustum 2, and the cement fiber board contacts the top cover 16. Multiple support blocks 12 and the top cover 16 support the cement fiber board. Then, the saw blade body 7 rotates for cutting. The electromagnets 9 are turned on. The electromagnets 9 on both sides of the saw blade body 7 form a combined magnetic field below the saw blade, with a stronger magnetism. The horizontal moving seat 3 moves, and the transverse moving seat 5 moves on the surface of the cross beam 4 to adjust the positions of the lifting seat 6 and the saw blade body 7. Then, the lifting seat 6 descends, driving the saw blade body 7, the housing 8, and the electromagnets 9 to descend. The electromagnet 9 is set with the downward magnetic pole as N (the electromagnet 9 can change the magnetic pole by changing the current direction). At the same time, the upward magnetic pole of the permanent magnet 18 is N. Using the principle of like poles repelling each other, when the electromagnet 9 descends or approaches the support block 12 during movement, the permanent magnet 18 overcomes the acting force from the compression spring 15 to drive the top cover 16 and the support block 12 to descend, causing the support block 12 near the periphery of the saw blade body 7 to descend, making its height lower than the surrounding support blocks 12, preventing the situation where the saw blade body 7 contacts the support block 12 or the top cover 16 due to over - deep cutting, resulting in damage.

[0024] During the process of the magnetic field generated by the electromagnet 9 repelling the permanent magnet 18, the support block 12 descends, driving the bottom cover 14 and the movable rod 201 to descend, putting the compression spring 15 in a compressed state. At the same time, the movable rod 201 drives the piston plate 204 to descend. During the descent of the piston plate 204, the one - way cover 208 is lifted upward by the hydraulic pressure until it contacts the limiting rod 207 (the limiting rod 207 prevents the one - way cover 208 from opening up to 90°). At this time, the arc - shaped groove 2011 is in an open state (as Figure 11 shown), enabling the hydraulic oil to pass through the larger arc - shaped groove 2011. When the piston plate 204, the movable rod 201, the bottom cover 14, and the support block 12 descend, they are subject to less hydraulic resistance, facilitating the rapid descent of the support block 12; after the saw blade body 7, the housing 8, and the electromagnets 9 move away from the previously descended support block 12, due to the lack of repulsive force, at this time the compression spring 15 pushes the bottom cover 14 and the support block 12 upward, driving the movable rod 201 and the piston plate 204 to rise at the same time. The one - way cover 208 closes under pressure (as Figure 9 shown), implementing a large - area blockage of the arc - shaped groove 2011. The hydraulic oil can only pass through the through - hole 209. Therefore, when the piston plate 204, the movable rod 201, the bottom cover 14, and the support block 12 rebound and rise, they are subject to greater resistance, preventing the support block 12 from rebounding too fast and causing damage to the bottom of the cement fiber board.

[0025] The flipping mechanism 21 includes a hydraulic cylinder 211, a lifting plate 212 and a rack 213. The number of hydraulic cylinders 211 is multiple groups and they are bolted to the inside of the machine body 1. The lifting plate 212 is bolted to the output shaft of the hydraulic cylinder 211. The rack 213 is bolted to the top of the lifting plate 212. Vertical plates 217 are bolted to the top of the machine body 1 and on both sides of the table body 2. Connecting plates 214 are bolted to both sides of the table body 2. A connecting column 215 is welded to the surface of the connecting plate 214, and the connecting column 215 is rotatably connected to the surface of the vertical plate 217, which enables the table body 2 and the rotating column 206 to rotate. A rack 213 is bolted to the surface of the connecting column 215 and the rack 213 meshes with the transmission gear 216. A through groove 218 is opened at the top of the machine body 1 for the rack 213 to pass through.

[0026] During the idle process of the equipment, if it is necessary to disassemble the outer cylinder 10 to maintain the internal components, just move the horizontal moving seat 3, the cross beam 4, the lateral moving seat 5, etc. to above the position far away from the table body 2 (as Figure 15 shown), then start the hydraulic cylinder 211 to extend its output shaft, thereby driving the lifting plate 212 and the rack 213 to rise. The engaged transmission gear 216 makes a counterclockwise rotational movement, thereby driving the rotating column 206 and the connecting plate 214 to rotate, and driving the table body 2 to flip. A sliding rod 219 is also bolted to the inside of the machine body 1. A sliding sleeve 2110 is bolted to one side of the rack 213, and the sliding sleeve 2110 is slidably connected to the surface of the sliding rod 219. The rack 213 can drive the sliding sleeve 2110 to slide along the surface of the sliding rod 219 during the rising process, increasing the stability of the rack 213 during the upward movement. A limiting plate 2111 is bolted above the surface of the sliding rod 219, and the sliding sleeve 2110 contacts the limiting plate 2111. Close the hydraulic cylinder 211, and the sliding sleeve 2110 and the rack 213 stop rising. Then the top of the table body 2 flips to the lower side, exposing the multiple outer cylinders 10 at its bottom to the outside, so as to disassemble and take them out for maintenance work. There is no need for the staff to enter the inside of the machine body 1 for disassembly, which brings convenience to the maintenance operation; after the maintenance work is completed, start the hydraulic cylinder 211 to contract its output shaft to reset the table body 2.
