Description

Technical Field

[0001] The present invention relates to the technical field of stone cutting equipment, and particularly relates to a cutting equipment for dividing large stones based on building aggregate production. Background Art

[0002] In the building block manufacturing industry, the quality and supply efficiency of building aggregates have a significant impact on the entire production process. As an important source of building aggregates, large stones need to be divided before actual utilization. Traditional stone dividing methods, such as manual hammering and crushing or operating small and simple cutting equipment, have obvious drawbacks. Manual operation not only has a high labor intensity and extremely low efficiency, but also it is difficult to control the dividing accuracy, resulting in uneven sizes of the produced aggregates, which affects the forming quality of subsequent building blocks. The cutting ability of small equipment is limited, and it is difficult to handle large stones, unable to meet the needs of large-scale production. With the rapid development of the construction industry, the requirements for the quality and output of building blocks are constantly increasing.

[0003] In the patent with the publication number CN114953212A, a cutting equipment for ore processing is disclosed. Its structure includes a cutting mechanism, an operating table, a support frame, and a base. The operating table is movably engaged with the upper surface of the support frame, the bottom of the support frame is welded to the top of the base, and the cutting mechanism passes through the inside of the operating table and is connected to the upper surface of the support frame. By squeezing a pointed stone between two clamping strips, the two clamping strips can clamp the pointed stone, and through the blocking groove, the speed at which the pointed stone slides off between the two clamping strips can be decreased, so as to buffer the rebound force after the pointed stone impacts the inner wall of the protective cover. After the reset strip stops rotating in the anti-touch groove, it can reversely push the transition block to reset along the ring body, and then through the grasping force generated by the inner concave cavity on the inner side of the ore, when the movable block resets, the yellow soil attached between the ore cutting surface and the blade can be grabbed and scattered, so that the ore can be quickly separated from the blade after cutting is completed.

[0004] The existing technology has the following defects: Single cutting method: When the existing cutting equipment cuts, a wire saw is mostly used for large irregular stones, and a saw blade is used for small regular stones. Facing stones of different specifications, the equipment needs to be frequently changed, which not only consumes manpower and time, reduces production efficiency, but also limits the application range of the equipment. Therefore, it is necessary to set up a structure with adjustable cutting methods to avoid the cumbersome process of changing equipment, save manpower and time, make the production process smoother, accurately adapt to various types of stones, and thus improve the overall production efficiency and stone processing quality.

[0005] The efficiency is low when cutting large irregular stones: The shapes of large irregular stones vary greatly, with uneven surfaces, protruding edges and corners, and lack of regular planes and unified shapes. As a result, it is difficult for cutting equipment to find stable and suitable cutting points and cutting paths. Moreover, the power and cutting ability of the wire saw itself are limited, making it difficult to provide a sufficiently powerful cutting force, which leads to a very slow cutting process. Therefore, a structure for saw blade grooving needs to be set before cutting large irregular stones to provide a stable and suitable cutting point and cutting path for subsequent wire saw cutting, effectively avoiding cutting problems caused by the irregular shape of the stones. At the same time, grooving can reduce the resistance of wire saw cutting to a certain extent, make up for the deficiency of the power and cutting ability of the wire saw, speed up the cutting speed, reduce pauses and adjustments during the cutting process, and thus significantly improve the overall cutting efficiency. Summary of the Invention

[0006] In view of the problems in the prior art such as a single cutting method and low efficiency when cutting large irregular stones, a cutting device for dividing large stones based on building aggregate production is proposed.

[0007] This application provides a cutting device for dividing large stones based on building aggregate production, and its purpose is: By setting a saw blade cutting mechanism and a wire saw cutting mechanism, the cutting method can be flexibly adjusted, avoiding the cumbersome process of frequently replacing equipment, saving manpower and time, making the production process smoother, being able to accurately adapt to various stones, and thus improving the overall production efficiency and the quality of stone processing. When cutting large irregular stones, first use the saw blade to groove to provide a stable and suitable cutting point and path for subsequent wire saw cutting, effectively avoiding cutting problems caused by the irregular shape of the stones. At the same time, grooving can reduce the resistance of wire saw cutting to a certain extent, make up for the deficiency of its power and cutting ability, speed up the cutting speed, reduce cutting pauses and adjustments, and significantly improve the overall cutting efficiency.

[0008] The technical solution of the present invention is: A cutting device for dividing large stones based on building aggregate production includes a gantry, a saw blade cutting mechanism and a wire saw cutting mechanism arranged inside the gantry, and a handling component arranged below the gantry. The saw blade cutting mechanism includes a transverse movement component slidably connected to the inner wall of the gantry. The transverse movement component includes a fixed cross bar arranged above the handling component. The outer wall of the fixed cross bar is slidably connected with a transverse movement frame, and a tensioning component and a rotating component are arranged outside the transverse movement frame; The tensioning component includes a protective cover fixedly connected to the outer wall of the transverse movement frame. The top of the protective cover is fixedly connected with a tensioning frame. An upper arc groove is opened above the tensioning frame, a lower transverse groove is opened below the tensioning frame, and two limiting rods are fixedly connected to the bottom of the protective cover.

[0009] With the above solution, by setting the saw blade cutting mechanism and the wire saw cutting mechanism, when the stone to be cut is a regular stone such as a cube or a cuboid, the saw blade is used for cutting. The transverse moving frame slides on the fixed cross bar to move the diamond saw blade to the appropriate cutting position, and then the rotating component is started to cut the stone. When the height of the stone is less than or equal to the cutting height of the diamond saw blade, it can be directly cut; when the height of the stone is greater than the cutting height of the diamond saw blade, the limiting rod at the bottom of the protective cover contacts the surface of the stone to prevent the diamond saw blade from being damaged by excessive downward pressure. At this time, the diamond saw blade cannot cut downward but can cut horizontally. Then, it is switched to wire saw cutting. During wire saw cutting, the upper arc groove in the tensioning frame can drive the square diamond wire saw to move upward for adjustment.

[0010] Further, the rotating component includes a driving motor fixedly connected to the outer wall of the transverse moving frame and a rotating shaft rotatably connected to the outer wall of the transverse moving frame. A speed increasing transmission belt is fixedly installed between the output shaft of the driving motor and the outer wall of the rotating shaft. The outer wall of the rotating shaft is fixedly connected with a diamond saw blade, and the diamond saw blade is located inside the protective cover and between the two limiting rods.

[0011] With the above solution, through the set rotating component, the driving motor drives the rotating shaft to rotate at a high speed through the speed increasing transmission belt, and then the diamond saw blade fixed on the outer wall of the rotating shaft rotates to cut the stone, playing a role in cutting.

[0012] Further, the wire saw cutting mechanism includes a stepping motor fixedly installed on the outer wall of the gantry, a first fixed wheel, two second fixed wheels and two movable components. The output shaft of the stepping motor is fixedly connected with a driving wheel, and a plurality of clamping grooves are formed in the inner wall of the driving wheel. The driving wheel is drivingly connected with a diamond wire saw through the plurality of clamping grooves.

[0013] Further, the movable component includes two movable support frames fixedly connected to the inner wall of the gantry. The inner walls of the two movable support frames are both slidably connected with movable carts. A support spring is fixedly connected between the bottom of each of the two movable carts and the gantry. A movable wheel is fixedly connected between the two movable carts. The outer wall of the diamond wire saw is slidably connected with the inner walls of the first fixed wheel, the two second fixed wheels and the two movable wheels respectively.

[0014] With the above solution, through the set wire saw cutting mechanism, since the diamond wire saw is in a ring design, when the upper arc groove in the tensioning frame drives the upper diamond wire saw to move upward, the change in the tension of the ring-shaped wire saw will cause the movable wheel to be pulled downward by the lower diamond wire saw, so that the lower diamond wire saw is embedded in the cutting groove reserved by the previous saw blade cutting and provides tension. Then, the stepping motor drives the driving wheel to rotate, and the driving wheel drives the diamond wire saw to drive through the clamping grooves. The diamond wire saw sequentially bypasses the first fixed wheel, the two second fixed wheels and the two movable wheels for cutting.

[0015] Further, the transverse movement assembly further includes a transverse movement driving device installed between the fixed cross bar and the transverse movement frame. Lifting vehicles are fixedly connected to both ends of the fixed cross bar, and a lifting assembly is installed between the tops of the two lifting vehicles.

[0016] Further, the lifting assembly includes an output winch and a synchronous winch fixedly installed on the top of the gantry. A connecting shaft is fixedly connected between the output winch and the synchronous winch. Steel wire ropes are fixedly connected to the output ends of the output winch and the synchronous winch respectively. The bottoms of the two steel wire ropes are fixedly connected to the tops of the two lifting vehicles respectively.

[0017] Further, the lifting assembly further includes two lifting grooves opened inside the gantry. The inner walls of the two lifting grooves are slidably connected to the outer walls of the two lifting vehicles respectively.

[0018] With the above scheme, by setting the transverse movement assembly and the lifting assembly, when using the saw blade for cutting, the output winch and the synchronous winch installed on the top of the gantry rotate synchronously through the connecting shaft; the output ends of the output winch and the synchronous winch release or retract the steel wire ropes, driving the lifting vehicles at both ends of the fixed cross bar to slide in the lifting grooves, so as to adjust the height of the fixed cross bar; then, the transverse movement driving device drives the transverse movement frame to slide on the fixed cross bar, moving the diamond saw blade to a suitable cutting position.

[0019] Further, the handling assembly includes a conveying device arranged below the fixed cross bar. The output end of the conveying device is fixedly connected to a steering device, and the output end of the steering device is fixedly connected to a bearing plate.

[0020] With the above scheme, by setting the handling assembly, a large stone is placed on the bearing plate, conveyed to the cutting area by the conveying device, and the direction of the stone is adjusted by the steering device according to the cutting requirements, so that the stone can be parked on the bearing plate in a suitable posture. After that, a suitable cutting method can be selected according to the specifications and shapes of the stones.

[0021] The beneficial effects of the present invention: 1. With the provided saw blade cutting mechanism and wire saw cutting mechanism, when the stone to be cut is a regular stone such as a cube or a cuboid, the saw blade is used for cutting. When the height of the stone is less than or equal to the cutting height of the diamond saw blade, direct cutting can be carried out. When the height of the stone is greater than the cutting height of the diamond saw blade, the limit rod at the bottom of the protective cover contacts the stone surface to prevent the diamond saw blade from being damaged due to excessive downward pressure. At this time, the diamond saw blade cannot cut downward and can cut horizontally. Then, it switches to wire saw cutting. During wire saw cutting, the upper arc groove in the tensioning frame can drive the square diamond wire saw to move upward, so that the cutting method can be flexibly adjusted, avoiding the cumbersome process of frequently replacing equipment, saving manpower and time, making the production process smoother, being able to accurately adapt to various stones, and thus improving the overall production efficiency and the quality of stone processing.

[0022] 2. With the provided wire saw cutting mechanism, since the diamond wire saw is in a ring design, when the upper arc groove in the tensioning frame drives the upper diamond wire saw to move upward, the change in the tension of the ring-shaped wire saw will cause the movable wheel to be pulled downward by the lower diamond wire saw, making the lower diamond wire saw embed into the cutting groove reserved by the previous saw blade cutting and providing tension. Then, the stepping motor drives the driving wheel to rotate, and the driving wheel drives the diamond wire saw to transmit through the card slot. The diamond wire saw sequentially bypasses the first fixed wheel, two second fixed wheels and two movable wheels for cutting, playing the role of using wire saw cutting.

[0023] 3. With the provided transverse movement component and lifting component, when using the saw blade for cutting, the output winch and the synchronous winch installed on the top of the gantry rotate synchronously through the connecting shaft; the output ends of the output winch and the synchronous winch release or retract the steel wire rope, driving the lifting vehicles at both ends of the fixed cross bar to slide in the lifting groove, thereby adjusting the height of the fixed cross bar; then, the transverse movement driving device drives the transverse movement frame to slide on the fixed cross bar, moving the diamond saw blade to the appropriate cutting position, playing the role of saw blade cutting.

[0026] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific implementation manners of the present invention with reference to the accompanying drawings of the specification.

[0027] Refer to Figures 1-12 , a cutting device for dividing large stones based on building aggregate production is provided, including a gantry 1, a saw blade cutting mechanism 2 and a wire saw cutting mechanism 3 arranged inside the gantry 1, and a handling component 4 arranged below the gantry 1. The saw blade cutting mechanism 2 includes a transverse movement component 22 slidably connected to the inner wall of the gantry 1. The transverse movement component 22 includes a fixed cross bar 222 arranged above the handling component 4. The outer wall of the fixed cross bar 222 is slidably connected with a transverse movement frame 223. A tensioning component 23 and a rotating component 24 are arranged outside the transverse movement frame 223.

[0028] Refer to Figures 5-7, the tensioning assembly 23 includes a protective cover 231 fixedly connected to the outer wall of the transverse movement frame 223. A tensioning frame 232 is fixedly connected to the top of the protective cover 231. An upper arc groove 233 is formed above the tensioning frame 232, and a lower transverse groove 234 is formed below the tensioning frame 232. Two limiting rods 235 are fixedly connected to the bottom of the protective cover 231.

[0029] Specifically, the saw blade cutting mechanism 2 is used for initially cutting large stones or cutting stones with regular shapes. An upper arc groove 233 is formed above the tensioning frame 232. The upper arc groove 233 has a specific radian and size, and its function is to guide and tension the diamond wire saw 33 during the wire saw cutting process to ensure the stable operation of the wire saw. A lower transverse groove 234 is formed below the tensioning frame 232. The lower transverse groove 234 cooperates with the upper arc groove 233 to jointly complete the tensioning and adjustment of the wire saw, so that the wire saw can maintain an appropriate tension during the cutting process, improving the cutting efficiency and quality. The limiting rod 235 can play a limiting role during the cutting process. When the cutting depth reaches a certain level, the limiting rod 235 will contact the stone surface to prevent the diamond saw blade 243 from pressing down excessively, avoiding damage to the saw blade and ensuring the safety and stability of the cutting process.

[0030] Through the arranged saw blade cutting mechanism 2 and wire saw cutting mechanism 3, when the stone to be cut is a regular stone such as a cube or a cuboid, the saw blade cutting is used. The transverse movement frame 223 slides on the fixed cross bar 222 to move the diamond saw blade 243 to a suitable cutting position, and the rotation assembly 24 is started to cut the stone. When the height of the stone is less than or equal to the cutting height of the diamond saw blade 243, direct cutting can be carried out. When the height of the stone is greater than the cutting height of the diamond saw blade 243, the limiting rod 235 at the bottom of the protective cover 231 contacts the stone surface to prevent the diamond saw blade 243 from pressing down excessively and being damaged. At this time, the diamond saw blade 243 cannot cut downward and can cut horizontally. Then it is switched to wire saw cutting. During wire saw cutting, the upper arc groove 233 in the tensioning frame 232 can drive the square diamond wire saw 33 to move upward for adjustment.

[0031] Refer to Figures 5-6 , the rotation assembly 24 includes a driving motor 241 fixedly connected to the outer wall of the transverse movement frame 223, and a rotating shaft 244 rotatably connected to the outer wall of the transverse movement frame 223. A speed increasing transmission belt 242 is fixedly installed between the output shaft of the driving motor 241 and the outer wall of the rotating shaft 244. A diamond saw blade 243 is fixedly connected to the outer wall of the rotating shaft 244. The diamond saw blade 243 is located inside the protective cover 231 and between the two limiting rods 235.

[0032] Through the provided rotating assembly 24, the driving motor 241 drives the rotating shaft 244 to rotate at a high speed through the speed-increasing transmission belt 242, and then the diamond saw blade 243 fixed on the outer wall of the rotating shaft 244 rotates to cut the stone, playing a cutting role.

[0033] Referring to Figures 8-10 , the wire saw cutting mechanism 3 includes a stepping motor 31 fixedly installed on the outer wall of the gantry 1, a first fixed wheel 35, two second fixed wheels 36 and two movable components 34. The output shaft of the stepping motor 31 is fixedly connected with a driving wheel 32. A plurality of card slots are formed in the inner wall of the driving wheel 32, and the driving wheel 32 is drivingly connected with a diamond wire saw 33 through the plurality of card slots.

[0034] Referring to Figures 8-10 , the movable component 34 includes two movable support frames 341 fixedly connected to the inner wall of the gantry 1. Movable carts 343 are slidably connected to the inner walls of the two movable support frames 341. Support springs 344 are fixedly connected between the bottoms of the two movable carts 343 and the gantry 1. An movable wheel 342 is fixedly connected between the two movable carts 343. The outer wall of the diamond wire saw 33 is slidably connected to the inner walls of the first fixed wheel 35, the two second fixed wheels 36 and the two movable wheels 342 respectively.

[0035] Through the provided wire saw cutting mechanism 3, since the diamond wire saw 33 is annularly designed, when the upper arc groove 233 in the tensioning frame 232 drives the upper diamond wire saw 33 to move upward, the change in the tension of the annular wire saw will cause the movable wheel 342 to be pulled downward by the lower diamond wire saw 33, so that the lower diamond wire saw 33 is embedded in the cutting groove reserved by the previous saw blade cutting and provides tension. Then, the stepping motor 31 drives the driving wheel 32 to rotate, and the driving wheel 32 drives the diamond wire saw 33 to drive through the card slots. The diamond wire saw 33 sequentially bypasses the first fixed wheel 35, the two second fixed wheels 36 and the two movable wheels 342 for cutting.

[0036] Referring to Figures 2-5 , the transverse movement component 22 further includes a transverse movement driving device 224 installed between the fixed cross bar 222 and the transverse movement frame 223. Lifting carts 221 are fixedly connected to both ends of the fixed cross bar 222. A lifting component 21 is installed between the tops of the two lifting carts 221. The lifting component 21 includes an output winch 211 and a synchronous winch 215 fixedly installed on the top of the gantry 1. A connecting shaft 214 is fixedly connected between the output winch 211 and the synchronous winch 215. Steel wire ropes 213 are fixedly connected to the output ends of the output winch 211 and the synchronous winch 215 respectively. The bottoms of the two steel wire ropes 213 are fixedly connected to the tops of the two lifting carts 221 respectively. The lifting component 21 further includes two lifting grooves 212 formed in the interior of the gantry 1. The inner walls of the two lifting grooves 212 are slidably connected to the outer walls of the two lifting carts 221 respectively.

[0037] Through the provided transverse movement component 22 and lifting component 21, when using the saw blade for cutting, the output winch 211 and synchronous winch 215 installed at the top of the gantry 1 rotate synchronously through the connecting shaft 214; the output ends of the output winch 211 and synchronous winch 215 release or retract the steel wire rope 213, driving the lifting vehicles 221 at both ends of the fixed cross bar 222 to slide in the lifting groove 212, thereby adjusting the height of the fixed cross bar 222; then, the transverse movement driving device 224 drives the transverse movement frame 223 to slide on the fixed cross bar 222, moving the diamond saw blade 243 to a suitable cutting position.

[0038] Refer to Figures 11-12 , the handling component 4 includes a conveying device 41 arranged below the fixed cross bar 222, the output end of the conveying device 41 is fixedly connected with a steering device 43, and the output end of the steering device 43 is fixedly connected with a bearing plate 42.

[0039] Through the provided handling component 4, a large stone is placed on the bearing plate 42, conveyed to the cutting area through the conveying device 41, and the direction of the stone is adjusted by the steering device 43 according to the cutting requirements, so that the stone can be parked on the bearing plate 42 in a suitable posture. After that, a suitable cutting method can be selected according to the specifications and shape of the stone.

[0040] During use, large stones are placed on the bearing plate 42, transported to the cutting area by the conveying device 41, and the direction of the stones is adjusted by the steering device 43 according to the cutting requirements, so that the stones can be parked on the bearing plate 42 in a suitable posture, and a suitable cutting method is selected according to the specifications and shapes of the stones. When the stones to be cut are regular stones such as cubes or cuboids, a saw blade is used for cutting. When the height of the stone is less than or equal to the cutting height of the diamond saw blade 243, direct cutting can be carried out. When the height of the stone is greater than the cutting height of the diamond saw blade 243, the limiting rod 235 at the bottom of the protective cover 231 contacts the surface of the stone to prevent the diamond saw blade 243 from being damaged by excessive downward pressure. At this time, the diamond saw blade 243 cannot cut downward and can be cut horizontally, and then converted to wire saw cutting. During wire saw cutting, since the diamond wire saw 33 is designed in a ring shape, when the upper arc groove 233 in the tensioning frame 232 drives the upper diamond wire saw 33 to move upward, the change in the tension of the ring-shaped wire saw will cause the movable wheel 342 to be pulled downward by the lower diamond wire saw 33, so that the lower diamond wire saw 33 is embedded in the cutting groove reserved by the previous saw blade cutting and provides tension. Then, the stepping motor 31 is operated for cutting. When the stones to be cut are irregular stones, first use the diamond saw blade 243 to open a groove, and then use the diamond wire saw 33 for cutting, effectively avoiding the cutting problems caused by the irregular shape of the stones. At the same time, grooving can reduce the wire saw cutting resistance to a certain extent, make up for the deficiencies in its power and cutting ability, speed up the cutting speed, reduce cutting pauses and adjustments, and significantly improve the overall cutting efficiency.

[0041] The working principle of the present invention: During operation, large stones are placed on the bearing plate 42, transported to the cutting area by the conveying device 41, and the direction of the stones is adjusted by the steering device 43 according to the cutting requirements, so that the stones can be parked on the bearing plate 42 in a suitable posture, and a suitable cutting method is selected according to the specifications and shapes of the stones.

[0042] When the stones to be cut are regular stones such as cubes or cuboids, a saw blade is used for cutting. The output winch 211 and the synchronous winch 215 installed on the top of the gantry 1 rotate synchronously through the connecting shaft 214. The output ends of the output winch 211 and the synchronous winch 215 release or retract the steel wire rope 213, driving the lifting vehicles 221 at both ends of the fixed cross bar 222 to slide in the lifting groove 212, thereby adjusting the height of the fixed cross bar 222. Then, the transverse movement driving device 224 drives the transverse movement frame 223 to slide on the fixed cross bar 222, and moves the diamond saw blade 243 to a suitable cutting position.

[0043] Start the rotating assembly 24. The driving motor 241 drives the rotating shaft 244 to rotate at a high speed through the speed-increasing transmission belt 242, and then rotates the diamond saw blade 243 fixed on the outer wall of the rotating shaft 244 to cut the stone. When the height of the stone is less than or equal to the cutting height of the diamond saw blade 243, direct cutting can be carried out. When the height of the stone is greater than the cutting height of the diamond saw blade 243, the limiting rod 235 at the bottom of the protective cover 231 contacts the surface of the stone to prevent the diamond saw blade 243 from being damaged by excessive downward pressure. At this time, the diamond saw blade 243 cannot cut downward and can cut horizontally, and then switch to wire saw cutting.

[0044] During wire saw cutting, first move the fixed cross bar 222 upward to reset, and then convey the stone to the wire saw cutting position through the conveying device 41. The fixed cross bar 222 continues to move upward. Since the diamond wire saw 33 is designed in a ring shape, when the upper arc groove 233 in the tensioning frame 232 drives the upper diamond wire saw 33 to move upward, the change in the tension of the ring-shaped wire saw will cause the movable wheel 342 to be pulled downward by the lower diamond wire saw 33, so that the lower diamond wire saw 33 is embedded in the cutting groove reserved by the previous saw blade cutting and provides tension. Then, the stepping motor 31 drives the driving wheel 32 to rotate, and the driving wheel 32 drives the diamond wire saw 33 to transmit through the card slot. The diamond wire saw 33 sequentially bypasses the first fixed wheel 35, two second fixed wheels 36 and two movable wheels 342 for cutting.

[0045] When the stone to be cut is an irregular stone, first use the diamond saw blade 243 to open a slot, and then use the diamond wire saw 33 to cut, which can effectively avoid the cutting problems caused by the irregular shape of the stone. At the same time, slotting can reduce the wire saw cutting resistance to a certain extent, make up for the deficiencies in its power and cutting ability, speed up the cutting speed, reduce cutting pauses and adjustments, and significantly improve the overall cutting efficiency.

[0046] After a cutting is completed, the handling assembly 4 transports the cut stone away, and a new stone is conveyed in. The equipment repeats the above work process to achieve continuous and efficient stone splitting operations, improving the overall production efficiency and stone processing quality.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
