Description

Technical Field

[0001] The present invention relates to the technical field of stone cutting, and particularly to a stone cutting device and method with a splash-proof function. Background Art

[0002] Existing stone cutting equipment can often only perform single-sided cutting. When the thickness fluctuation range of the stone is relatively large, conventional cutting equipment cannot meet the usage requirements.

[0003] Currently, during the stone cutting process, existing stone cutting equipment is prone to generating a large amount of debris. Due to the centrifugal force of cutting, the debris is easily driven to splash along the cutting direction, with a wide radiation area and a large impact. This not only threatens the safety of operators but also greatly increases the cleaning difficulty of the cutting device to a certain extent.

[0004] In addition, due to the thickness of the stone not being guaranteed and possibly fluctuating within a relatively large range, conventional cutting devices use a single blade for cutting and cannot adjust the cutting depth. When cutting with a fixed cutting depth, collisions may occur. Summary of the Invention

[0005] The purpose of the present invention is to provide a stone cutting device and method with a splash-proof function to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A stone cutting device and method with a splash-proof function.

[0007] A stone cutting device with a splash-proof function, the cutting device is used to cut stones. The cutting device includes a conveying device, a driving device, an adjusting device, and a material collecting device. The conveying device is used to convey stones. The driving device is connected to the conveying device through the adjusting device, and the adjusting device is in transmission connection with the conveying device. There are two groups of driving devices arranged vertically. The two driving devices cut different layer thicknesses of the stone. The material collecting device is in transmission connection with the lower driving device, and the material collecting device is used to collect cutting powder.

[0008] The conveying device, as the main installation foundation, is used to convey stones. When the stones are conveyed to the cutting station, the driving device is used to perform layered cutting on the stones, that is, the upper and lower driving devices cut the stones simultaneously. The layer thickness cut by the upper layer is higher than that of the lower layer, which is convenient for automatically collecting debris through the material collecting device and for real-time monitoring of the cutting state. When the thickness of the stone fluctuates, based on the change in the cutting depth, the adjusting device automatically adjusts the cutting depths of the upper and lower driving devices so that the cutting depths of the upper and lower layers always maintain a fixed ratio.

[0009] Furthermore, the conveying device includes a carrier, a conveying motor and a conveying roller, a plurality of conveying rollers are provided, the plurality of conveying rollers are rotatably connected to the carrier, the conveying motor is firmly connected to the carrier, the output end of the conveying motor is drivingly connected to the conveying roller, two transverse module groups are provided on the carrier, and the movable ends of the two transverse module groups are firmly connected to the adjusting device respectively;

[0010] The adjusting device includes a mounting seat, the movable end of the transverse module is fastened to the mounting seat, the mounting seat is connected to the driving device, the driving device includes a driving motor and a slide seat, the slide seat is connected to the mounting seat, the driving motor and the slide seat are fastened, two driving motors are provided, a transmission shaft is provided at the output end of the driving motor, an upper cutting knife and a lower cutting knife are respectively provided on the two transmission shafts, and the cutting depth of the upper cutting knife is higher than the cutting depth of the lower cutting knife.

[0011] The carrier is used to install the conveying motor and conveying roller. The conveying motor outputs torque, and the conveying roller can maintain chain drive or belt drive, thereby driving the conveying roller to rotate on the carrier. During the rotation, the stone is conveyed in a direction and sent to the cutting station for automatic loading and unloading. The fixed ends of the two transverse module groups are respectively fixed on the carrier and are located on the upper and lower layers of the conveying roller. The displacement output direction of the transverse module group is parallel to the axis of the conveying roller. The movable end is fixedly connected to the mounting seat to drive the driving device to move. The driving motor is fixed on the slide seat and outputs torque. The upper cutting knife and the lower cutting knife are driven to rotate through the transmission shaft, thereby cutting the stone. The material is cut by setting the cutting depth of the two cutting knives differently. The direction of the debris jet cut by the upper cutting knife is inclined downward, and the direction of the debris jet cut by the lower cutting knife is inclined upward, and the number of upper jet debris is greater than that of the lower jet debris. Since the components of the upper and lower jet debris in the vertical direction are opposite, the upper jet debris impacts the lower jet debris to reduce energy, and the upward movement of the lower jet debris is hindered, while the downward movement speed of the upper jet debris is correspondingly reduced by the impact, and the lower jet debris is entrained, and finally falls into the material collecting device at an angle downward, so as to facilitate the directional collection of the debris and prevent splashing.

[0012] Furthermore, the cutting depth of the upper cutting knife is twice that of the lower cutting knife. The cutting depth of the upper cutting knife accounts for two-thirds of the stone, and the cutting depth of the lower cutting knife is one-third.

[0013] Furthermore, the driving device also includes a detection component, which includes a resistance strain gauge, a conductive slip ring and a bracket. The bracket is tightly connected to the driving motor housing, and two ring grooves are provided on the bracket. The conductive slip ring is placed in the two ring grooves. The inner sides of both ends of the resistance strain gauge are tightly connected to the outer cylindrical surface of the transmission shaft respectively, and the outer sides of both ends of the resistance strain gauge are in contact with the two conductive slip rings respectively. The resistance strain gauge is electrically connected to two wiring terminals of the power supply through the two conductive slip rings to form a detection circuit.

[0014] The torsional deformation of the transmission shaft is detected by setting a detection component. The torsional deformation of the transmission shaft is caused by the resistance of the cutting knife to the stone cutting, that is, the larger the overlapping surface of the cutting, the greater the torsional deformation of the transmission shaft. The two ends of the resistance strain gauge are respectively fastened to the outer circle of the transmission shaft. Through the deformation fixed at both ends, when the transmission shaft is torsional deformed, the resistance strain gauge is driven to stretch. During the stretching process, the resistance value increases, and the current value of the circuit connected by the conductive slip ring and the power supply decreases. That is, the larger the overlapping surface of the cutting, the smaller the current value of the detection circuit.

[0015] Furthermore, the adjusting device also includes an adjusting cylinder, the adjusting cylinder and the mounting seat are fastened together, the adjusting cylinder output end and the sliding seat are fastened together, the sliding seat and the mounting seat are slidably connected, and the adjusting cylinder and the adjacent detection circuit are electrically connected.

[0016] The adjusting cylinder is installed and fixed by the mounting seat. When the thickness of the cut stone is uneven, for example, when the thickness increases, the overlapping surface of the upper cutting increases, the current value of the detection circuit decreases, and at the same time, the two adjusting cylinders are controlled to output displacement upward, driving the two cutting knives to move up at the same time, so that the thickness of the upper and lower cutting layers returns to the initial proportion.

[0017] Furthermore, the upper cutting blade and the lower cutting blade are located at the same cutting stroke length.

[0018] The upper cutting knife and the lower cutting knife are driven synchronously, that is, the travel speed is consistent, which facilitates the impact of the jet debris. The upward force of the jet debris in the lower layer is offset by the component force in the vertical direction to avoid the debris splashing.

[0019] Furthermore, the material receiving device includes a material receiving pipe and a spray pipe, the material receiving pipe is connected to the lower slide seat by transmission, a feeding channel is provided on the material receiving pipe, the spray pipe and the feeding channel are connected, a guide paddle is provided at the feeding channel near the outlet of the spray pipe, the guide paddle is firmly connected to the wall of the feeding channel, a material receiving trough is provided on one side of the feeding channel, and the material receiving trough faces the direction of splashing of cutting debris.

[0020] The thickness of the upper cutting blade and the lower cutting blade is automatically adjusted so that the debris from the two layers of jets still moves downward obliquely after impact, and enters the feeding channel through the receiving trough. The atomized water droplets are pressurized and sent into the feeding channel through the spray pipe, and hit the guide paddle, which is a propeller. The airflow flows through the gap between the blades and moves forward in a spiral along the subsequent feeding channel. By applying a spiral water vapor layer, the debris entering the receiving trough is restrained to prevent the debris from escaping again.

[0021] As an optimization, the receiving device also includes a shield, and a contraction cavity is provided on both sides of the receiving trough. The shield and the contraction cavity are slidably connected, and the contraction cavity is filled with compressed gas. The shield is provided with a transmission surface, and the two transmission surfaces are far away from each other. By setting the shield, the inlet of the receiving trough is initially sealed. When the debris jet hits the shield, it is transmitted through the transmission surface, driving the shield to open to both sides. The compressed gas is further compressed during the opening process, so that the size of the receiving opening can be automatically adjusted according to the amount of debris.

[0022] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention sets the cutting depths of the two cutting knives differently, the direction of the debris jet cut by the upper cutting knife is inclined downward, the direction of the debris jet cut by the lower cutting knife is inclined upward, and the number of the upper jet debris is greater than the lower jet debris. Since the components of the upper and lower jet debris in the vertical direction are opposite, the upper jet debris impacts the lower jet debris to reduce its energy, the lower jet debris is blocked from moving upward, and the speed of the upper jet debris moving downward is correspondingly reduced by the impact, and the lower jet debris is entrained, and finally falls obliquely downward into the collecting device, which is convenient for directional collection of the debris and prevents splashing; the torsional deformation of the transmission shaft is converted into cutting The resistance caused by the cutting knife when cutting the stone, that is, the larger the overlapping surface of the cutting, the greater the degree of torsional deformation of the transmission shaft, the two ends of the resistance strain gauge are respectively fastened to the outer circle of the transmission shaft, and through the deformation of the double-end fixation, when the transmission shaft is torsional, the resistance strain gauge is driven to stretch. During the stretching process, the resistance value increases, and the current value of the circuit connected by the conductive slip ring and the power supply decreases, that is, the larger the overlapping surface of the cutting, the smaller the current value of the detection circuit; when the thickness of the cut stone is uneven, for example, when the thickness increases, the overlapping surface of the upper cutting increases, the current value of the detection circuit decreases, and at the same time, the two adjusting cylinders are controlled to output the displacement upward, driving the upper cutting knife and the lower cutting knife to move up at the same time, so that the thickness of the upper and lower cutting layers returns to the initial proportion.

[0032] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] The present invention provides a technical solution:

[0034] As Figures 1 to 2 shown, a stone cutting device with an anti-splash function, the cutting device is used to cut the stone material 5, the cutting device includes a conveyor device 1, a driving device 2, an adjusting device 3 and a material receiving device 4, the conveyor device 1 is used to convey the stone material 5, the driving device 2 is connected to the conveyor device 1 through the adjusting device 3, the adjusting device 3 is in transmission connection with the conveyor device 1, two groups of driving devices 2 are arranged vertically, the two driving devices 2 cut different layer thicknesses of the stone material 5, and the material receiving device 4 is in transmission connection with the lower driving device 2, and the material receiving device 4 is used to collect the cutting powder.

[0035] The conveyor device 1 serves as the main installation foundation for conveying the stone material 5. When the stone material 5 is conveyed to the cutting station, the stone material 5 is cut layer by layer by the driving device 2, that is, the upper and lower driving devices 2 cut the stone material 5 simultaneously, and the layer thickness of the upper layer cutting is higher than that of the lower layer, which is convenient for automatically collecting the debris by the material receiving device 4 and monitoring the cutting state in real time. When the thickness of the stone material 5 fluctuates, based on the change of the cutting depth, the cutting depths of the upper and lower driving devices 2 are automatically adjusted by the adjusting device 3, so that the cutting depths of the upper and lower layers always maintain a fixed ratio.

[0036] As Figures 1 to 3As shown, the conveying device 1 includes a carrier 11, a conveying motor 12 and a conveying roller 13, a plurality of conveying rollers 13 are provided, the plurality of conveying rollers 13 are rotatably connected to the carrier 11, the conveying motor 12 is firmly connected to the carrier 11, the output end of the conveying motor 12 is drivingly connected to the conveying roller 13, two transverse module groups 14 are provided on the carrier 11, and the movable ends of the two transverse module groups 14 are firmly connected to the adjusting device 3 respectively;

[0037] The adjusting device 3 includes a mounting seat 31, the movable end of the transverse module 14 is fastened to the mounting seat 31, the mounting seat 31 is connected to the driving device 2, the driving device 2 includes a driving motor 21 and a slide 25, the slide 25 is connected to the mounting seat 31, the driving motor 21 and the slide 25 are fastened to each other, two driving motors are provided, a transmission shaft 24 is provided at the output end of the driving motor 21, an upper cutting knife 22 and a lower cutting knife 26 are respectively sleeved on the two transmission shafts 24, and the cutting depth of the upper cutting knife 22 is higher than the cutting depth of the lower cutting knife 26.

[0038] The carrier 11 is used to install the conveying motor 12 and the conveying roller 13. The conveying motor 12 outputs torque, and the conveying roller 13 can maintain chain drive or belt drive, thereby driving the conveying roller 13 to rotate on a fixed axis on the carrier 11. During the rotation, the stone 5 is directionally conveyed and sent to the cutting station for automatic loading and unloading. The fixed ends of the two transverse modules 14 are respectively fixed on the carrier 11 and are located on the upper and lower layers of the conveying roller 13. The displacement output direction of the transverse module 14 is parallel to the axis of the conveying roller 13. The movable end is fixedly connected to the mounting seat 31, which is used to drive the driving device 2 to move. The driving motor 21 is fixed on the slide 25 and outputs torque. The upper cutting knife 22 and the lower cutting knife 26 are driven to rotate through the transmission shaft 24, thereby cutting the stone 5. During cutting, the tooth shapes of the upper cutting knife 22 and the lower cutting knife 26 are staggered to prevent tooth collision. By setting the cutting depth difference between the upper cutting knife 22 and the lower cutting knife 26, the debris jet direction cut by the upper cutting knife 22 is inclined downward, and the debris jet direction cut by the lower cutting knife 26 is inclined upward, and the number of upper jet debris is greater than that of the lower jet debris. Since the components of the upper and lower jet debris in the vertical direction are opposite, the upper jet debris collides with the lower jet debris to reduce energy, and the upward movement of the lower jet debris is blocked, while the downward movement speed of the upper jet debris is correspondingly reduced by the impact, and the lower jet debris is entrained, and finally falls into the collecting device 4 at an angle downward, so as to facilitate the directional collection of the debris and prevent splashing.

[0039] like Figure 5 As shown, the cutting depth of the upper cutting knife 22 is twice that of the lower cutting knife 22. The cutting depth of the upper cutting knife 22 accounts for two-thirds of the stone, and the cutting depth of the lower cutting knife 26 is one-third.

[0040] like Figures 4 to 5As shown in the figure, the driving device 2 further includes a detection component 23. The detection component 23 includes a resistance strain gauge 231, a conductive slip ring 232, and a bracket 233. The bracket 233 is fixedly connected to the housing of the driving motor 21. There are two annular grooves provided on the bracket 233. The conductive slip ring 232 is placed in the two annular grooves. The inner sides of both ends of the resistance strain gauge 231 are fixedly connected to the outer cylindrical surface of the transmission shaft 24 respectively. The outer sides of both ends of the resistance strain gauge 231 are in contact with the two conductive slip rings 232 respectively. The resistance strain gauge 231 is electrically connected to the two wiring terminals of the power supply through the two conductive slip rings 232 to form a detection circuit.

[0041] By providing the detection component 23 to detect the torsional deformation of the transmission shaft 24, the torsional deformation of the transmission shaft 24 is caused by the resistance during the cutting of the stone material 5 by the cutting knife 22. That is, the larger the overlapping surface of the cutting is, the greater the degree of torsional deformation of the transmission shaft 24. Both ends of the resistance strain gauge 231 are respectively fastened to the outer circle of the transmission shaft 24. Through the deformation of double-end fixation, when the transmission shaft 24 undergoes torsional deformation, it drives the resistance strain gauge 231 to be stretched. During the stretching process, the resistance value increases, and the current value of the circuit electrically connected by the conductive slip ring 232 and the power supply decreases. That is, the larger the overlapping surface of the cutting is, the smaller the current value of the detection circuit is.

[0042] As Figures 1 to 2 As shown in the figure, the adjusting device 3 further includes an adjusting cylinder 32. The adjusting cylinder 32 is fixedly connected to the mounting seat 31. The output end of the adjusting cylinder 32 is fixedly connected to the sliding seat 25. The sliding seat 25 is slidably connected to the mounting seat 31. The adjusting cylinder 32 is electrically connected to the adjacent detection circuit.

[0043] The adjusting cylinder 32 is installed and fixed through the mounting seat 31. When the thickness of the cut stone material 5 is uneven, for example, when the thickness increases, the overlapping surface of the upper layer cutting increases, and the current value of the detection circuit decreases. At the same time, control the two adjusting cylinders 32 to output displacement upward, driving the upper cutting knife 22 and the lower cutting knife 26 to move upward simultaneously, so that the cutting thickness of the upper and lower layers returns to the initial ratio.

[0044] As Figure 3 As shown in the figure, the upper cutting knife 22 and the lower cutting knife 26 are located at the same length of the cutting stroke.

[0045] Through the synchronous driving setting of the upper cutting knife 22 and the lower cutting knife 26, that is, the traveling speeds are the same, which is convenient for the impact of the debris of the jet flow. Through the component force in the vertical direction, the upward component force of the debris of the lower layer jet flow is offset, avoiding the splashing of the debris.

[0046] As Figures 6 to 7As shown in the figure, the material receiving device 4 includes a material receiving pipe 41 and a spray pipe 43. The material receiving pipe 41 is drivingly connected to the lower sliding seat 25. A feeding channel 411 is provided on the material receiving pipe 41. The spray pipe 43 is communicated with the feeding channel 411. A guiding paddle 42 is provided near the outlet of the spray pipe 43 in the feeding channel 411. The guiding paddle 42 is fixedly connected to the wall surface of the feeding channel 411. A material receiving groove 412 is provided on one side of the feeding channel 411, and the material receiving groove 412 faces the direction of cutting debris splashing.

[0047] Through the automatic adjustment of the thickness of the upper cutting knife 22 and the lower cutting knife 26, after the debris of the two-layer jets impacts, it still moves obliquely downward and enters the feeding channel 411 through the material receiving groove 412. The atomized water droplets are pressurized and sent into the feeding channel 411 through the spray pipe 43, and impact into the guiding paddle 42. The guiding paddle 42 is a propeller, so that the air flow passes through the gaps between the blades and spirally moves forward along the subsequent feeding channel 411. By applying a spiral water vapor layer, the debris entering the material receiving groove 412 is constrained to prevent the debris from escaping again.

[0048] As an optimization, the material receiving device 4 further includes a shielding plate 44. Shrinkage cavities 413 are respectively provided on both sides of the material receiving groove 412. The shielding plate 44 is slidably connected to the shrinkage cavities 413. Compressed gas is filled in the shrinkage cavities 413. A transmission surface is provided on the shielding plate 44, and the distal ends of the two transmission surfaces face away from each other. By providing the shielding plate 44, the inlet of the material receiving groove 412 is initially sealed. When the debris jet impacts the shielding plate 44, it is transmitted through the transmission surface to drive the shielding plate 44 to open to both sides. During the opening process, the compressed gas is further compressed, which is convenient for automatically adjusting the size of the material receiving opening according to the amount of debris.

[0049] The cutting method includes the following steps:

[0050] S1. Drive the conveying roller 13 to rotate through the conveying motor 12, so as to automatically load the stone material 5 and convey the stone material 5 to the cutting station.

[0051] S2. When the stone material 5 is conveyed to the cutting station, cut the stone material 5 respectively by the upper cutting knife 22 and the lower cutting knife 26. The debris forms an impact under the centrifugal force. The debris on the upper layer is larger than that on the lower layer, so that the debris on the upper layer impacts and reduces the energy of the debris on the lower layer, which is convenient for directional collection.

[0052] S3. Through the detection component 23 provided on the transmission shaft 24, detect the torsional deformation of the transmission shaft 24, so as to detect the cutting coincidence surface of the upper cutting knife 22. According to the detection result, adjust the relative height of the upper cutting knife 22 and the lower cutting knife 26 through the adjusting cylinder 32, so as to keep the cutting thickness ratio of the upper and lower layers fixed.

[0053] S4. When the cutting ratio of the upper and lower layers is fixed, since there are more debris in the upper layer, the debris jet of the lower layer is driven into the receiving pipe 41 under the action of centrifugal force, and the debris is restrained by the spiral water vapor in the feeding channel 411 to prevent it from escaping, thereby improving the debris collection efficiency.

[0054] The working principle of the present invention is as follows: by setting the cutting depth difference between the upper cutting blade 22 and the lower cutting blade 26, the debris jet direction cut by the upper cutting blade 22 is inclined downward, and the debris jet direction cut by the lower cutting blade 26 is inclined upward, and the number of upper jet debris is greater than that of the lower jet debris. Since the components of the upper and lower jet debris in the vertical direction are opposite, the upper jet debris impacts the lower jet debris to reduce energy, and the lower jet debris is blocked from moving upward, while the speed of the upper jet debris moving downward is correspondingly reduced by the impact, and the lower jet debris is entrained, and finally falls obliquely downward into the collecting device 4, so as to facilitate the directional collection of the debris and prevent splashing; the torsional deformation of the transmission shaft 24 becomes an obstacle when the cutting blade cuts the stone 5. The force is caused, that is, the larger the overlapping surface of the cutting, the greater the degree of torsional deformation of the transmission shaft 24. The two ends of the resistance strain gauge 231 are respectively fastened to the outer circle of the transmission shaft 24. Through the deformation of the double-end fixation, when the transmission shaft 24 is torsional, the resistance strain gauge 231 is driven to stretch. During the stretching process, the resistance value increases, and the current value of the circuit connected to the power supply through the conductive slip ring 232 decreases, that is, the larger the overlapping surface of the cutting, the smaller the current value of the detection circuit; when the thickness of the cut stone 5 is uneven, for example, when the thickness increases, the overlapping surface of the upper cutting increases, the current value of the detection circuit decreases, and at the same time, the two adjusting cylinders 32 are controlled to output displacement upward, driving the upper cutting knife 22 and the lower cutting knife 26 to move up at the same time, so that the thickness of the upper and lower cutting layers returns to the initial proportion.

[0055] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
