Description

Technical Field

[0001] This invention relates to the field of cutting device technology, and more specifically, to a plate-shaped aluminum silicate thickness cutting device. Background Technology

[0002] Due to its excellent high-temperature resistance, thermal insulation, and chemical stability, plate-shaped aluminum silicate is widely used in high-temperature equipment insulation layers and refractory linings in metallurgy, building materials, and chemical industries. In practical applications, precise thickness cutting of the plate-shaped aluminum silicate is required according to the equipment dimensions. The quality of the cutting process directly determines the subsequent assembly accuracy and thermal insulation and refractory performance. Therefore, efficient and high-quality cutting equipment has become a key industry requirement. Currently, plate-shaped aluminum silicate cutting equipment in the industry faces several technical challenges in practical applications, as detailed below: The microstructure of plate-shaped aluminum silicate is mainly composed of fibrous crystals, and its macroscopic characteristics include brittleness and low impact strength, far lower than that of conventionally cut materials such as metals and wood. Existing cutting devices generally employ two cutting methods: one is fixed-angle cutting, where a rigid blade presses down along a fixed trajectory to cut, concentrating the cutting force on a single contact line. When the cutting force exceeds the crack resistance limit of aluminum silicate, longitudinal cracks are easily generated along the cutting line, leading to edge chipping of the plate. The second method is constant-amplitude vibration cutting. Cutting is achieved by vertically vibrating the cutting wire with constant amplitude. However, constant-amplitude vibration will generate a continuous and uniform impact force on the board, causing local stress concentration in the cutting area. Especially at the edges and corners of the board, where there is no support and constraint from adjacent materials, the stress is easy to exceed the limit, leading to edge and corner breakage. Based on this, the present invention provides a plate-shaped aluminum silicate thickness cutting device to solve the problems mentioned in the background art. Summary of the Invention

[0003] This invention addresses the technical problems existing in the prior art by providing a plate-shaped aluminum silicate thickness cutting device to solve the problem that existing cutting devices are prone to edge chipping and corner breakage.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A plate-shaped aluminum silicate thickness cutting device includes a frame and an execution frame that can move relative to it on two axes. A central control unit is installed on the execution frame, and a cutting wire is also included. A pressure frame is slidably connected to the execution frame and a motor is fixedly mounted thereon.

A follower spring is installed on the side of the follower slide, and the other end of the follower spring is fixedly connected to the execution frame. A movable compensation wheel is rotatably connected to the follower slide. A second belt is driven through the output shaft of the motor. Both the movable compensation wheel and the pressing wheel are driven through the second belt. Along the circumferential direction, two pressing wire meshing tooth segments and two second toothless non-meshing segments are alternately arranged on the pressing wheel. A vertical rack is installed on the pressing knife frame. The two pressing wire meshing tooth segments are alternately meshed with the vertical rack, and the transmission strokes of the two pressing wire meshing tooth segments to the vertical rack are different. Two return springs are installed on the bottom surface of the pressing knife frame, and the other ends of the two return springs are fixedly connected to the execution frame.

[0009] As a preferred technical solution of the present invention, the oscillating wire assembly includes an inner shaft, a main shaft rotatably connected to the pressure frame, and two auxiliary shafts. The inner shaft is drivenly connected to the main shaft, the main shaft is drivenly connected to a second belt, a third belt is drivenly connected to the inner shaft, both auxiliary shafts are drivenly connected to the third belt, and an oscillating drive gear is installed on each of the two auxiliary shafts. A hollow oscillating sleeve is rotatably connected to the inner shaft, the hollow oscillating sleeve is fixedly connected to the oscillating tool holder, and the hollow oscillating sleeve is rotatably connected to the pressure frame. A second torsion spring is provided at the rotatable connection between the two. An oscillating driven gear is installed on the hollow oscillating sleeve, and the two oscillating drive gears alternately mesh with the oscillating driven gear.

[0010] As a preferred technical solution of the present invention, the center angles corresponding to the effective meshing sections on the two swing drive gears are both 35°. The two swing drive gears are respectively arranged on both sides of the swing driven gear. The installation phase difference of the effective meshing sections on the two swing drive gears is 180°. The swing tool holder is provided with a guide arc groove, and the pressure frame is equipped with a limiting guide post that cooperates with the guide arc groove.

[0011] As a preferred technical solution of the present invention, the reciprocating sawing drive assembly includes a reciprocating drive wheel mounted on an inner shaft. Along the circumferential direction, the reciprocating drive wheel is alternately provided with two sawing meshing tooth segments and two third toothless non-meshing segments. A horizontal toothed plate is mounted on the sawing frame. The two sawing meshing tooth segments alternately mesh with the horizontal toothed plate, and the transmission strokes of the two sawing meshing tooth segments to the horizontal toothed plate are different. A sliding return spring is installed between the sawing frame and the swing blade holder.

[0012] As a preferred technical solution of the present invention, an outer rotating sleeve is rotatably sleeved on the hollow swing sleeve, the outer rotating sleeve is connected to the second belt drive, a power guide shaft is rotatably connected to the swing blade holder, and a linkage bevel gear is installed on both the power guide shaft and the outer rotating sleeve. The two linkage bevel gears are orthogonally meshed, and a third belt is connected between the power guide shaft and the hexagonal shaft.

[0013] As a preferred technical solution of the present invention, the cutting mechanism further includes a hollow shaft rotatably connected to the sawing frame. The hollow shaft has a hollow guide groove with openings at both ends and slidably connected to a hexagonal shaft. The cross-sections of the hollow guide groove and the hexagonal shaft are both regular hexagonal. A fourth belt is connected between the hollow guide groove and the rotating frame. A guide wheel that fits against the cutting wire is rotatably connected to the rotating frame.

[0014] The beneficial effects of this invention are: 1. This invention solves the problems of existing devices where fixed-angle rigid blade cutting, due to the concentration of cutting force on a single contact line, easily exceeds the crack resistance limit of aluminum silicate, leading to breakage, and where constant-range vibration cutting wires, due to continuous and uniform impact, cause stress concentration at the edges and corners, resulting in detachment. The reciprocating pressure blade assembly drives the cutting wire to achieve unequal-range vibration of 1.5mm and 2.25mm, avoiding continuous impact. The wire swing assembly controls the cutting wire to swing precisely at ±10°, dispersing the stress at the contact point. The reciprocating sawing drive assembly drives the cutting wire to slide back and forth, achieving multiple small-amplitude cuts. All three are synchronized by the same motor. This multi-action coordinated design avoids the concentration of cutting force and, compared to existing single cutting actions, can effectively reduce the edge breakage and corner chipping rate during the cutting of brittle aluminum silicate.

[0015] 2. This invention solves the problem of frequent replacement of existing devices where the cutting wire is prone to wear and breakage due to fiber entanglement and local overheating by a system linkage of self-rotation of the cutting wire, synchronous winding and unwinding, and follow-up cooling. The hexagonal shaft drives the cutting wire to rotate around its own axis, breaking the fiber entanglement condition. The cutting wire wheel is synchronously wound and unwound under the action of the power ring and reciprocating bevel gear, dynamically switching the working section of the cutting wire. The cooling nozzle rotates with the rotating frame, and together with the corrugated cooling pipe, it achieves all-round cooling. The ±10° swing further expands the heat dissipation range. The multi-system collaboration prevents the cutting wire from local wear and overheating. Compared with the existing design that only relies on a single cooling system, the service life of the cutting wire is extended, and the cost of consumables is greatly reduced.

[0025] like Figure 1-9 As shown, a plate-shaped aluminum silicate thickness cutting device includes a frame 1 and an execution frame 2 that can move relative to it on two axes. A central control unit 3 is installed on the execution frame 2. It also includes cutting wire 4, which is made of diamond. The frame 1 is equipped with an annular discharge belt 20 and two annular conveyor belts 21. A conveyor gap is provided between the two annular conveyor belts 21. The aluminum silicate board to be cut is clamped in the conveyor gap. The frame 1 is also equipped with a transmission module 22 that drives the annular discharge belt 20 and the two annular conveyor belts 21 to rotate at the same speed. Specifically, the transmission module 22 is an existing mechanism, which will not be described in detail here. When the two annular conveyor belts 21 are working, they rotate in opposite directions at the same speed, thereby conveying the aluminum silicate board to be cut toward the direction of the cutting wire 4. When the transmission module 22 drives the two annular conveyor belts 21 to rotate in opposite directions at the same speed, it can stably clamp the aluminum silicate board to be cut through the conveyor gap, avoiding the deviation of the cutting position due to the offset during the conveying process. At the same time, the annular discharge belt 20 and the annular conveyor belt 21 rotate at the same speed, which can promptly transport the finished board to the next process after cutting, avoid the accumulation of finished products affecting the continuous cutting efficiency, realize the continuous operation of conveying, cutting and discharge, and improve the overall production rhythm. The actuator 2 is equipped with a dual-axis drive platform 23 and a liquid storage tank 24. The dual-axis drive platform 23 is connected to the actuator 2 in a drive connection. The actuator 2 is equipped with a collection box 25 with an open top, which is located on the actuator 2 and directly below the cutting wire 4. The liquid storage tank 24 is equipped with a pump body. The dual-axis transmission platform 23 can drive the execution frame 2 to flexibly achieve dual-axis movement. The position of the cutting component can be adjusted according to the size of the aluminum silicate board to be cut and the target cutting thickness, breaking the limitation of the fixed cutting range and improving the adaptability of the device. The collection box 25 directly below the cutting filament 4 can collect the cutting waste in a concentrated manner, reducing the pollution of the working environment caused by the waste scattering, reducing the subsequent cleaning cost, and taking into account both practicality and environmental protection. A pressure frame 5 is slidably connected to the actuator 2, and a motor 6 is fixedly mounted thereon. The output shaft of the motor 6 is equipped with a reciprocating pressure assembly that drives the pressure frame 5 to vibrate vertically. The reciprocating pressure knife assembly includes a pressure roller 27 rotatably connected to the actuator 2 and a follower slide 28 slidably connected to the actuator 2. A follower spring 29 is installed on the side of the follower slide 28, and the other end of the follower spring 29 is fixedly connected to the actuator 2. A movable compensation wheel 30 is rotatably connected to the follower slide 28. A second belt is driven to the output shaft of the motor 6. The movable compensation wheel 30 and the pressure wheel 27 are both driven to the second belt. Along the circumferential direction, two wire pressing meshing tooth sections 31 and two second toothless non-meshing sections are alternately arranged on the pressure wheel 27. A vertical rack 32 is installed on the pressure frame 5. The two wire pressing meshing tooth sections 31 are alternately meshed with the vertical rack 32, and the transmission strokes of the two wire pressing meshing tooth sections 31 to the vertical rack 32 are different. Two return springs 33 are installed on the bottom surface of the pressure frame 5. The other ends of the two return springs 33 are fixedly connected to the actuator 2. In a preferred embodiment, the diameter of the cutting wire 4 is 0.15 mm, and the thickness of the aluminum silicate board to be cut is 15 mm; The density of the aluminum silicate board to be cut is 200-300 kg / m3, and the fiber length is 5-10 mm; The transmission strokes of the two wire-pressing meshing tooth sections 31 to the vertical rack 32 are 1.5 mm and 2.25 mm, respectively; When the motor 6 drives the pressure roller 27 to rotate via the second belt, the two wire-pressing meshing tooth segments 31 on the pressure roller 27 with different transmission strokes alternately mesh with the vertical rack 32. In conjunction with the return spring 33, it can drive the pressure frame 5 and the cutting wire 4 to perform unequal vertical vibration. Plate-shaped aluminum silicate is brittle and has low impact resistance. Constant vertical vibration can easily cause local stress concentration and breakage due to continuous and uniform impact force. However, unequal vibration of 1.5mm and 2.25mm can make the cutting wire 4 alternately produce light cutting and heavy cutting action. The small stroke achieves precise cutting and reduces the impact on the material surface during the initial cutting. The large stroke efficiently cuts the internal structure and avoids the material from breaking due to long-term stress, which is suitable for the brittle characteristics of aluminum silicate. Aluminum silicate contains a fibrous structure. Iso-path vibration easily causes the cutting wire 4 to continuously rub and entangle with the fibers, and local heat accumulates quickly. Unequal-path vibration can dynamically change the contact position and force between the cutting wire 4 and the material. On the one hand, it breaks the stable conditions of fiber entanglement and prevents the cutting wire 4 from getting stuck. On the other hand, it disperses the friction points through stroke changes and, together with cooling, further reduces the local temperature, avoiding the cutting wire 4 from being worn or broken due to overheating.

[0026] During constant-path vibration cutting, the cutting wire 4 has a fixed shearing angle with the material, which makes it easy to form uniform burrs on the material edge. The alternating shearing force brought by unequal-path vibration can flexibly adapt to the uneven structural density inside aluminum silicate, reduce tearing damage on the material edge, and make the cut surface smoother. A swinging tool holder 7 is rotatably connected to the pressure frame 5, and a wire swinging assembly that drives the swinging tool holder 7 to swing at ±10° is provided on the output shaft of the motor 6. The oscillating cutter assembly includes an inner shaft 34, a main shaft 35 rotatably connected to the pressure frame 5, and two auxiliary shafts 36. The inner shaft 34 is driven by the main shaft 35, the main shaft 35 is driven by the second belt, and a third belt is driven by the inner shaft 34. Both auxiliary shafts 36 are driven by the third belt. Oscillating drive gears 37 are installed on both auxiliary shafts 36. A hollow swing sleeve 38 is rotatably connected to the inner shaft 34. The hollow swing sleeve 38 is fixedly connected to the oscillating cutter holder 7 and rotatably connected to the pressure frame 5. A second torsion spring 39 is provided at the rotatable connection between the two. An oscillating driven gear 40 is installed on the hollow swing sleeve 38. The two oscillating drive gears 37 are alternately meshed with the oscillating driven gear 40. The center angles corresponding to the effective meshing sections of the two swing drive gears 37 are both 35°. The two swing drive gears 37 are respectively set on both sides of the swing driven gear 40. The installation phase difference of the effective meshing sections of the two swing drive gears 37 is 180°. A guide arc groove is opened on the swing tool holder 7, and a limiting guide post 41 that cooperates with the guide arc groove is installed on the pressure frame 5. When the motor 6 drives the two secondary shafts 36 to rotate via belt drive, the swing drive gears 37 on both sides alternately mesh with the swing driven gears 40. In conjunction with the second torsion spring 39, the guide arc groove and the limit guide post 41, the swing blade holder 7 can be precisely controlled to drive the cutting wire 4 to swing at ±10°. When the 35° effective meshing section of each swing drive gear 37 rotates, it drives the swing driven gear 40 to rotate 10° to one side. A sawing frame 8 is slidably connected to the swing blade holder 7, and a hexagonal shaft 9 driven by a motor 6 is rotatably mounted on it. The output shaft of the motor 6 is also provided with a reciprocating sawing drive assembly that drives the sawing frame 8 to slide back and forth on the swing blade holder 7. The sawing frame 8 is provided with two symmetrical cutting mechanisms. The reciprocating sawing drive assembly includes a reciprocating drive wheel 42 mounted on an inner shaft 34. Along the circumferential direction, the reciprocating drive wheel 42 is alternately provided with two sawing meshing tooth segments 43 and two third toothless non-meshing segments. A horizontal toothed plate 44 is mounted on the sawing frame 8. The two sawing meshing tooth segments 43 are alternately meshed with the horizontal toothed plate 44, and the transmission strokes of the two sawing meshing tooth segments 43 to the horizontal toothed plate 44 are different. A sliding return spring 45 is installed between the sawing frame 8 and the swing blade holder 7. In a preferred embodiment, the driving strokes of the two sawing meshing tooth segments 43 to the horizontal tooth plate 44 are 3.5 cm and 5 cm, respectively; Plate-shaped aluminum silicate has poor impact resistance. When cut at a fixed angle, the cutting force is concentrated on a single contact line, which can easily exceed the material's crack resistance limit and cause it to crack along the cutting line. The ±10° swing allows the contact angle of the cutting wire 4 to switch dynamically. With the precise constraint of the swing trajectory by the limiting guide post 41, the cutting force is distributed to multiple instantaneous contact points, avoiding local stress concentration. This significantly reduces the chipping and corner breaking caused by brittle fracture during the cutting process and improves the finished product qualification rate.

[0027] Aluminum silicate contains a fibrous structure. When it is fixed for cutting, the fibers are prone to continuous friction with the cutting filament 4 and entanglement of the filament, resulting in a sudden increase in cutting resistance and filament jamming. The ±10° swing allows the contact position between the cutting filament 4 and the material to change in real time with the angle, which can actively peel off the attached fibers. Plate-shaped aluminum silicate has aggregates and uneven density inside. When cut at a fixed angle, high-density areas are prone to chipping and indentation, while low-density areas are prone to overcutting and burrs. The ±10° swing allows the cutting wire 4 to flexibly adapt to different density areas: when encountering high-density areas, a small angle adjustment makes it easier for the wire to cut into hard points. When encountering low-density areas, the angle change reduces excessive cutting. Combined with the monitoring of cutting force by the triaxial accelerometer 18, the final roughness of the cut surface is significantly reduced, and assembly or deep processing requirements can be met without subsequent grinding. The heat generated by the friction between the cutting wire 4 and the aluminum silicate tends to accumulate in the fixed contact area, causing the wire to overheat and soften, and wear to accelerate. The ±10° swing expands the heat dissipation range of the cutting wire 4, and at the same time drives the surrounding air flow to accelerate the heat diffusion. In addition, the cooling nozzle 26 swings synchronously with the wire sleeve 12, and the coolant can evenly cover the entire length of the cutting wire 4 and the cutting area, further suppressing local high temperature. The cutting mechanism includes a power ring 10 fixedly mounted on the sawing frame 8 and a rotating frame 11 rotatably connected to the sawing frame 8. A wire sleeve 12 is fixedly mounted on the axis of the rotating frame 11, and a wire wheel 13 and a belt shaft 14 are rotatably connected to the rotating frame 11. The two ends of the cutting wire 4 are respectively wound around the outer circumference of the two wire wheels 13. A first torsion spring 15 is provided at the rotatable connection between the wire wheel 13 and the rotating frame 11. A first belt is connected between the wire wheel 13 and the belt shaft 14. A reciprocating bevel gear 16 is mounted on the belt shaft 14. Along the circumferential direction, two bevel tooth sections 17 and two first toothless non-meshing sections are alternately arranged on the power ring 10. The reciprocating bevel gear 16 meshes with the bevel tooth sections 17. A three-axis accelerometer 18 and a vision probe 19 positioned directly opposite the cutting wire 4 are fixedly mounted on the sawing frame 8. The data terminals of the three-axis accelerometer 18 and the vision probe 19 are both connected to the central control unit 3.

[0028] The central control unit 3 is an embedded microcontroller, model STM32F407, whose signal output terminal is electrically connected to the motor 6 and the dual-axis transmission platform 23. The central control unit 3 adjusts the speed of the motor 6 and the displacement stroke and speed of the dual-axis transmission platform 23 in real time based on the cutting vibration acceleration data collected by the triaxial accelerometer 18 and the offset data of the cutting wire 4 collected by the vision probe 19, so as to realize the dynamic adjustment of the cutting wire 4 during the cutting operation. The pump body's outlet port is connected to a corrugated cooling pipe, and the end of each wire sleeve 12 is rotatably connected to a cooling nozzle 26. The corrugated cooling pipe and the cooling nozzle 26 are fixedly connected.

[0029] The nozzle diameter of the cooling nozzle 26 is 0.5 mm, and its spray direction is at an angle of 45° with the cutting wire 4. The coolant stored in the liquid storage tank 24 is water-soluble cutting fluid. The cooling system, consisting of the liquid storage tank 24, pump body, corrugated cooling pipe and cooling spray pipe 26, can continuously cool the cutting wire 4 and the cutting part, prevent the cutting wire 4 from being worn or broken due to high temperature, and at the same time avoid the aluminum silicate plate from cracking or deforming due to high temperature. The collection box 25 below the cutting wire 4 can collect the excess spray liquid sprayed out by the cooling nozzle 26; The cutting wire 4 rotates around its own axis and achieves stable power transmission through the cooperation of the hexagonal shaft 9 and the hollow shaft 48 with the regular hexagonal hollow guide groove; Motor 6 drives hexagonal shaft 9 to rotate via outer rotating sleeve 46 and power guide shaft 47. Hexagonal shaft 9 drives hollow shaft 48 to rotate, and then transmits to rotating frame 11 via fourth belt. This causes the cutting wire 4 fixed on the two cutting wire wheels 13 to rotate synchronously around its own axis with rotating frame 11. Guide wheel 49 then keeps in real time with cutting wire 4 to correct trajectory and prevent deviation. The reciprocating sawing action of the sawing frame 8 is driven by the reciprocating sawing drive assembly. The motor 6 drives the reciprocating drive wheel 42 on the inner shaft 34 to rotate. The two sawing meshing teeth 43 arranged alternately along the circumference of the wheel 42 mesh alternately with the horizontal tooth plate 44 of the sawing frame 8. With the help of the sliding return spring 45 between the sawing frame 8 and the swing blade holder 7, the sawing frame 8 can reciprocate along the swing blade holder 7. The synchronous winding and unwinding of the cutting wire wheel 13 relies on the meshing transmission between the power ring 10 and the reciprocating bevel gear 16. During the movement of the sawing frame 8, the two bevel tooth segments 17 fixed on the power ring 10 of the sawing frame 8 alternately mesh with the reciprocating bevel gear 16 with the shaft 14, and drive the cutting wire wheel 13 to rotate through the first belt. The first torsion spring 15 at the rotating connection between the cutting wire wheel 13 and the rotating frame 11 helps to maintain the basic tension of the cutting wire 4, thereby realizing the reciprocating winding and unwinding of the cutting wire 4. The rotating cutting wire 4 can dynamically switch its contact point with the material, avoiding overheating and wear or fiber entanglement and jamming at a single location due to continuous friction. The reciprocating sliding of the saw frame 8 forms multiple small-amplitude cuts, dispersing local cutting stress and preventing aluminum silicate from chipping or breaking off due to instantaneous impact exceeding its crack resistance limit. At the same time, it adapts to different density areas inside the material, avoiding chipping and denting in high-density areas and overcutting and burrs in low-density areas. The synchronous winding and unwinding of the wire wheel 13 reciprocates to change the working section of the cutting wire 4, reducing the wear rate of the cutting wire 4. The three functions work together to expand the heat dissipation range of the cutting wire 4. Combined with the cooling system, it further suppresses local high temperature, ultimately greatly improving the flatness of the cut surface and the cut qualification rate, reducing subsequent grinding processes, and extending the service life of the cutting wire 4.

[0030] The corrugated cooling pipe has flexible deformation characteristics and can adaptively adjust its shape as the cutting parts move, without hindering the movement of the parts and ensuring continuous delivery of coolant. The cooling nozzle 26 is rotatably connected to the end of the wire sleeve 12 and can rotate synchronously with the rotating frame 11 to achieve all-round cooling of the cutting wire 4 and the cutting part, avoiding local overheating that could cause wear of the cutting wire 4 or deformation of the aluminum silicate plate. Meanwhile, the coolant can lubricate the interface between the cutting wire 4 and the plate, reduce frictional resistance, extend the service life of the cutting wire 4, and also carry away the cutting debris with the coolant, further optimizing the quality of the cutting surface. The hollow swing sleeve 38 is rotatably fitted with an outer rotating sleeve 46, which is connected to the second belt drive. The swing tool holder 7 is rotatably connected with a power guide shaft 47. Both the power guide shaft 47 and the outer rotating sleeve 46 are equipped with linkage bevel gears. The two linkage bevel gears are orthogonally meshed. The power guide shaft 47 is connected to the hexagonal shaft 9 by a third belt.

[0031] The cutting mechanism also includes a hollow shaft 48 rotatably connected to the sawing frame 8. The hollow shaft 48 has a hollow guide groove with open ends and slidably connected to the hexagonal shaft 9. The cross-section of the hollow guide groove and the hexagonal shaft 9 are both regular hexagonal. A fourth belt is connected between the hollow guide groove and the rotating frame 11. A guide wheel 49 that fits against the cutting wire 4 is rotatably connected to the rotating frame 11. The guide wheel 49 is made of polyurethane. The hollow guide groove in the regular hexagonal shape cooperates with the hexagonal shaft 9 to achieve stable power transmission and allow the two to slide relative to each other when the sawing frame 8 slides, ensuring that the rotating frame 11 can still rotate stably during the movement of the sawing frame 8, so that the cutting wire 4 rotates synchronously with the rotating frame 11, improving the uniformity of cutting. The guide wheel 49 is set to fit the cutting wire 4, which can guide the movement trajectory of the cutting wire 4 in real time and prevent the cutting wire 4 from loosening or deviating; The first torsion spring 15 on the cutting wire wheel 13 can continuously maintain the consistent tension of the cutting wire 4, avoiding cutting deviation due to wire slack.

[0032] When the present invention is in operation, the transmission module 22 on the frame 1 drives two annular conveyor belts 21 to rotate in opposite directions at the same speed. The conveyor belts stably clamp and transport the aluminum silicate board to be cut to the direction of the cutting wire 4 through the conveyor gap. At the same time, the annular discharge belt 20 rotates at the same speed as the conveyor belts to prepare for the finished board to be transported to the next process. The execution frame 2 is driven by the dual-axis transmission platform 23 and adjusts its position according to the size of the aluminum silicate board to be cut and the target cutting thickness. Subsequently, the cutting drive system and the cutting execution system operate in coordination. The motor 6 drives the pressure roller 27 of the reciprocating pressure blade assembly to rotate via the second belt. The two wire-pressing meshing teeth 31 on the pressure roller 27 with different transmission strokes alternately mesh with the vertical rack 32 of the pressure blade frame 5. Together with the return spring 33, the pressure blade frame 5 drives the cutting wire 4 to perform unequal vertical vibration. On the other hand, it drives the main shaft 35 and inner shaft 34 of the wire swing assembly to rotate. The inner shaft 34 drives two auxiliary shafts via the third belt. The swing drive gear 37 on the shaft 36 and the secondary shaft 36 alternately mesh with the swing driven gear 40 of the hollow swing sleeve 38. Combined with the second torsion spring 39 and the limiting guide post 41, the swing blade holder 7 drives the cutting wire 4 to swing precisely within ±10°. At the same time, the inner shaft 34 drives the reciprocating drive wheel 42 of the reciprocating sawing drive assembly to rotate. Its sawing meshing tooth segment 43 alternately meshes with the horizontal tooth plate 44 of the sawing frame 8. With the help of the sliding return spring 45, the sawing frame 8 slides back and forth along the swing blade holder 7. Meanwhile, the cutting wire 4 in the cutting mechanism rotates under the power transmission. The motor 6 drives the hexagonal shaft 9 to rotate through the outer rotating sleeve 46 and the power guide shaft 47. The hexagonal shaft 9 drives the hollow shaft 48 to rotate through the regular hexagonal hollow guide groove. The hollow shaft 48 is transmitted to the rotating frame 11 through the fourth belt, which drives the cutting wire wheel 13 to rotate. The cutting wire wheel 13 realizes the synchronous winding and unwinding of the cutting wire 4 under the meshing action of the bevel tooth section 17 of the power ring 10 and the reciprocating bevel gear 16. The guide wheel 49 is in real time in contact with the cutting wire 4 to correct its movement trajectory. The coolant in the storage tank 24 is pumped to the corrugated cooling pipe, and then through the cooling spray pipe 26 which is rotatably connected to the wire sleeve 12, it rotates synchronously with the rotating frame 11 to cool the cutting wire 4 and the cutting part in all directions, while taking away the cutting debris. The central control unit 3 makes real-time adjustments. The three-axis accelerometer 18 on the sawing frame 8 monitors the changes in cutting force, and the vision probe 19 captures the status of the cutting filament 4. Both data are transmitted to the central control unit 3. The central control unit 3 fine-tunes parameters such as the position of the dual-axis transmission platform 23 and the speed of the motor 6 based on the data to ensure cutting accuracy.
