Description

Technical Field

[0001] This utility model relates to the technical field of stone slab processing equipment, and in particular to a multi-directional stone slab cutting device. Background Technology

[0002] As a natural decorative material, stone plays an important role in modern building curtain walls, floor paving, and irregularly shaped landscapes. With the rise of prefabricated buildings and personalized customization, large-sized stone slabs need to be quickly cut into finished products with multiple angles and specifications, which places higher demands on the spatial positioning capabilities and directional adaptability of cutting equipment.

[0003] Existing production lines generally use bridge-type single-axis cutting machines or cantilever-type dual-axis platforms. The typical approach is to arrange a set of longitudinally moving saws on the crossbeam and lay tracks on both sides of the worktable to achieve transverse feeding. Some high-end models use a gantry frame with a rotating base to achieve diagonal cutting by flipping the sheet metal.

[0004] However, the above-mentioned equipment reveals a common defect when dealing with continuous multi-directional cutting tasks: the sawing unit can only move along a preset straight trajectory. If the cutting direction needs to be changed, the stone slab must be re-clamped or rotated, resulting in process interruption and accumulation of positioning errors, making it difficult to balance efficiency and accuracy. Utility Model Content

[0005] The purpose of this invention is to propose a multi-directional stone slab cutting device to solve the problems of low efficiency and large errors caused by the fixed cutting direction and the need for repeated clamping of stone slabs in the existing technology.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A multi-directional stone slab cutting device includes a cross module, which consists of a transverse module and a longitudinal module. The longitudinal module is arranged along the length of the stone slab on both sides of the stone slab, and the transverse module spans the upper part of the stone slab with both ends installed on the longitudinal module. A lifting module is disposed at the moving end of the transverse module and moves with the cross module. A rotating mechanism and a cutting mechanism are respectively installed at the moving end of the lifting module. The lifting module drives the cutting mechanism to descend and cut the stone slab, and the rotating mechanism drives the cutting mechanism to cut the stone slab in different directions.

[0007] By adopting the above technical solution, the cross module allows the lifting module to be positioned at any position in the horizontal plane. The lifting module sends the cutting mechanism to the cutting height, and the rotating mechanism changes the cutting direction in real time. Multi-directional continuous cutting can be completed without moving the stone slab, thereby shortening the process time and reducing positioning errors.

[0008] Furthermore, the lifting module includes a back plate fixed to the moving end of the horizontal module, a lead screw rotatably mounted on the back plate, and guide rails fixed to both sides of the lead screw. Slide plates are provided on the guide rails and the lead screw, and the cutting mechanism and the rotating mechanism are respectively mounted on the slide plates.

[0009] By adopting the above technical solution, the lead screw-guide rail combination provides high-precision linear guidance for the slide, ensuring consistent cutting depth, and has a compact structure that is easy to integrate into the transverse module.

[0010] Furthermore, the cutting mechanism includes a bearing sleeve longitudinally fixed to the slide plate, a roller shaft rotatably disposed within the bearing sleeve, a saw blade rotatably disposed at the bottom of the roller shaft, and the top of the roller shaft connected to the rotating mechanism.

[0011] By adopting the above technical solution, the rotation of the roller within the bearing sleeve can drive the saw blade to change the cutting angle, achieving stepless steering, simplifying the mechanical structure and improving the response speed.

[0012] Furthermore, a bearing is fixed at the bottom end of the roller shaft, and a driven shaft is rotatably arranged inside the bearing. The driven shaft is arranged laterally and the saw blade is installed at its end.

[0013] By adopting the above technical solution, the horizontally arranged driven shaft makes the saw blade perpendicular to the stone slab surface, and the cutting force acts directly on the processing surface, reducing lateral force and improving the cut quality.

[0014] Furthermore, a bracket is fixed on the roller shaft, a motor is mounted on the bracket, and pulleys are fixedly mounted on the output shaft of the motor and the driven shaft, respectively.

[0015] By adopting the above technical solution, the motor drives the driven shaft through the belt drive, realizing high-speed rotation of the saw blade. The belt drive buffers the impact, making maintenance convenient and cost-effective.

[0016] Furthermore, a protective cover is fitted around the outer periphery of the saw blade, and the protective cover is fixed to the bearing.

[0017] By adopting the above technical solution, the protective cover moves synchronously with the saw blade, blocking the high-speed cutting edge in real time, reducing operational risks and dust diffusion.

[0018] Furthermore, the rotating mechanism includes a mounting plate fixed to the slide plate, a hydraulic cylinder rotatably mounted on the mounting plate, and a lever rotatably connected to the hydraulic cylinder. The middle part of the lever is fixedly connected to the roller shaft, and a limit mechanism is provided at one end of the lever.

[0019] By adopting the above technical solution, the hydraulic cylinder extends and retracts to drive the lever to swing, thereby driving the roller to rotate. The hydraulic system outputs a large torque and responds quickly, which can meet the turning requirements of large-sized saw blades.

[0020] Furthermore, the limiting mechanism includes a vertical plate fixed to the slide plate and an L-shaped plate slidably disposed on the top of the vertical plate. A strip groove is provided on the L-shaped plate, and a rotating block is provided at one end of the lever, the rotating block sliding in the strip groove.

[0021] By adopting the above technical solution, the rotating block slides along the strip groove, driving the L-shaped plate to move on the vertical plate. The mechanical limit is used to precisely control the rotation angle of the lever, preventing the saw blade from over-rotating and improving the consistency of the cutting angle.

[0022] Compared with the prior art, the present invention has the following beneficial effects: The multi-directional stone slab cutting equipment of this utility model utilizes a cross module to achieve arbitrary positioning in the horizontal plane, completing multiple cuts without moving the stone slab, significantly shortening the processing cycle. Through the linkage of the lifting module and the rotating mechanism, the saw blade is synchronously controlled in both vertical and rotational directions, achieving multi-directional cutting with a single clamping and reducing repeated positioning errors. The lead screw-guide rail structure provides stable lifting for the cutting mechanism, ensuring uniform cut depth and improving the yield. The limiting mechanism, in conjunction with the hydraulic drive, ensures precise and controllable saw blade rotation angle, preventing overcutting and improving the processing accuracy of complex contours.

[0028] Furthermore, in the description of this utility model, unless otherwise explicitly defined, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] This embodiment relates to a multi-directional stone slab cutting device. In terms of overall structure, as follows... Figure 1 , Figure 2 and Figure 3 As shown, it includes a cross module 1, a lifting module 2, a rotating mechanism 3, and a cutting mechanism 4.

[0031] The cross module 1 is installed along the length and width of the stone slab, and the lifting module 2 is installed at the moving end of the cross module 1. The cross module 1 drives the lifting module 2 to move to any position on the stone slab. The rotating mechanism 3 and the cutting mechanism 4 are installed at the moving end of the lifting module 2. The lifting module 2 drives the cutting mechanism 4 to descend and cut the stone slab. The rotating mechanism 3 drives the cutting mechanism 4 to cut the stone slab in different directions.

[0032] It is worth mentioning that the stone slab is placed on the platform, and the cross module 1 consists of a horizontal module 101 and a vertical module 102. The vertical module 102 is located on both sides of the length of the stone slab, and the horizontal module 101 spans across the upper part of the stone slab. The two ends of the horizontal module 101 are installed on the vertical module 102, ensuring that the vertical module 102 can drive the horizontal module 101 to move on the upper part of the stone slab. This arrangement enables the vertical module 102 to drive the lifting module 2 to move along the length of the stone slab, and the horizontal module 101 to drive the lifting module 2 to move along the width of the stone slab. In other words, the lifting module 2 can move to any position on the stone slab and can cut any position on the stone slab.

[0033] In addition, the lifting mechanism can drive the cutting mechanism 4 to rise and fall. When the stone slab needs to be cut, it only needs to be moved to this position, and the lifting mechanism will drive the cutting mechanism 4 to fall to this position on the stone slab for cutting. Of course, when the lifting mechanism moves with the cross module 1, the cutting mechanism 4 will rise with the lifting mechanism. The rotating mechanism 3 can drive the cutting mechanism 4 to rotate, ensuring that the cutting mechanism 4 cuts the stone slab in different directions. This setting enables the cutting mechanism 4 to cut large stone slabs into small stone slabs of different shapes and sizes, improving the automation and cutting accuracy of the equipment.

[0034] Based on the above overall introduction, an exemplary structure of the multi-directional stone slab cutting device in this embodiment is as follows: Figure 4 As shown, the lifting module 2 includes a back plate 201 fixedly mounted on the moving end of the cross module 1, a lead screw 202 rotatably mounted on the back plate 201, and guide rails 203 fixedly mounted on the back plate 201 and located on both sides of the lead screw 202. Slide plates 204 are provided on the guide rails 203 and the lead screw 202. The cutting mechanism 4 and the rotating mechanism 3 are respectively mounted on the slide plates 204.

[0035] It should be noted that the back plate 201 is fixedly installed on the moving end of the horizontal module 101, so that the lifting mechanism moves with the horizontal module 101. A servo motor is installed on the back plate 201 by screws. The servo motor is used to drive the lead screw 202 to rotate. The two ends of the lead screw 202 are rotatably connected to the back plate 201. The lead screw 202 is arranged longitudinally. The guide rail 203 is located on both sides of the lead screw 202 to assist the sliding plate 204 in lifting. The back of the sliding plate 204 is provided with a slider 205 that slides on the guide rail 203 and a screw sleeve 206 that is screwed to the lead screw 202. With this arrangement, when the lead screw 202 rotates, it can drive the screw sleeve 206 to move. The slider 205 can improve the stability of the sliding plate 204. The cutting mechanism 4 moves with the sliding plate 204 to cut the stone slab. The horizontal module 101 and the vertical module 102 of the cross module 1 have the same structure as the lifting module 2, and will not be described again here.

[0036] As a preferred implementation method, such as Figure 5 and Figure 6 As shown, the cutting mechanism 4 in this embodiment includes a bearing sleeve 401 fixedly mounted on the slide plate 204 and a roller 402 rotatably mounted inside the bearing sleeve 401. The top of the roller 402 is connected to the rotating mechanism 3, and a saw blade 403 is rotatably mounted at the bottom of the roller 402.

[0037] Specifically, the axial direction of the bearing sleeve 401 is parallel to the axial direction of the lead screw 202, both arranged longitudinally. A bracket 404 for mounting a motor 405 is fixedly installed on the roller 402. The motor 405 is mounted on the bracket 404. A bearing 406 is provided at the bottom of the roller 402. A driven shaft 407 for driving the saw blade 403 to rotate is rotatably installed inside the bearing 406. Pulleys 408 are respectively provided on the drive shaft of the motor 405 and the driven shaft 407. The pulleys 408 rotate through a belt. This arrangement enables the rotation of the saw blade 403. A protective cover 409 is fitted on the saw blade 403 and is fixedly installed on the bearing 406. The driven shaft 407 is arranged laterally to ensure that the saw blade 403 is perpendicular to the stone slab, thereby enabling it to cut the stone slab. The rotating mechanism 3 can drive the roller 402 to rotate to a specified position, and the saw blade 403 will rotate accordingly. This arrangement enables the saw blade 403 to cut the stone slab from different directions.

[0038] As a preferred implementation method, such as Figure 7 As shown, the rotating mechanism 3 in this embodiment includes a mounting plate 301 fixedly mounted on the slide plate 204, a hydraulic cylinder 302 rotatably mounted on the mounting plate 301, and a lever 303 fixedly mounted on the roller shaft 402. The drive shaft of the hydraulic cylinder 302 and the lever 303 are rotatably connected.

[0039] Specifically, the mounting plate 301 extends from one side of the slide plate 204 and is used to mount the hydraulic cylinder 302. The cylinder body of the hydraulic cylinder 302 is rotatably connected to the mounting plate 301. The middle part of the lever 303 is fixedly mounted on the top of the roller 402. One end of the lever 303 is rotatably connected to the piston rod of the hydraulic cylinder 302, and the other end is provided with a limit mechanism 5 to limit the rotation angle of the lever 303. When the hydraulic cylinder 302 is activated, it can push the lever 303 to rotate. The lever 303 drives the roller 402 to rotate, thereby driving the saw blade 403 to rotate.

[0040] As a preferred option, such as Figure 8 As shown, in this embodiment, the limiting mechanism 5 includes a vertical plate 501 fixedly installed on the slide plate 204. An L-shaped plate 502 is slidably arranged on the top of the vertical plate 501. A strip groove 503 is provided on the L-shaped plate 502. A rotating block 504 is provided at the other end of the lever 303. The rotating block 504 slides in the strip groove 503.

[0041] It should be noted that a through hole is provided on the upright plate 501, through which the roller shaft 402 passes and is connected to the lever 303. A slide rail 505 is provided on the upright plate 501, and the L-shaped plate 502 slides back and forth on the slide rail 505. A limit block 506 is provided on the slide rail 505 to limit the sliding distance of the L-shaped plate 502. The rotating block 504 is rotatably connected to the lever 303. When the hydraulic cylinder 302 drives the lever 303 to rotate, the lever 303 will push the L-shaped plate 502 to move. When it moves to the slide rail 501, the L-shaped plate 502 will move. The limiting block 506 of 05 is the maximum moving distance. When the L-shaped rod moves, the rotating block 504 on the lever 303 rotates in the strip groove 503. This setting can ensure that after the L-shaped plate 502 stops moving, the lever 303 also stops rotating, avoiding excessive rotation of the saw blade 403. In this example, the maximum rotation angle of the saw blade 403 is 90 degrees, ensuring that the cut stone slab is rectangular. The rotation of the saw blade 403 can improve the cutting efficiency of the stone slab, prevent the stone slab from moving, and also improve the cutting accuracy.

[0042] The multi-directional stone slab cutting device in this embodiment utilizes the cross module 1 to achieve arbitrary positioning in the horizontal plane, enabling multiple cuts to be completed without moving the stone slab, significantly shortening the processing cycle. Through the linkage between the lifting module 2 and the rotating mechanism 3, the saw blade 403 is synchronously controlled in both the vertical and rotational directions, achieving multi-directional cutting with a single clamping and reducing repeated positioning errors. The lead screw 202-guide rail 203 structure provides stable lifting for the cutting mechanism 4, ensuring uniform cutting depth and improving the yield rate. The limiting mechanism 5, in conjunction with the hydraulic drive, ensures precise and controllable rotation angle of the saw blade 403, preventing overcutting and improving the processing accuracy of complex contours.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
