Description

[Technical Field]

[0001] This invention relates to the field of stone cutting technology, and in particular to an oscillating stone cutting machine. [Background Technology]

[0002] Stone is widely used in construction. To turn a whole block of stone into slabs, cutting tools are needed to cut the stone. Traditionally used cutting tools include saw blades, saw bands, or wire saws. The cutting principle of these tools is to weld diamond cutting heads onto the saw blade or steel band, or to string diamond cutting heads together to form a wire saw.

[0003] Because diamond cutting heads are relatively large and need to be attached to a metal substrate, a 3-10mm kerf is typically formed during cutting, leading to stone waste and pollution. To address the problem of excessively large kerfs in traditional cutting tools, diamond wire cutting machines were developed. For example, Chinese invention patent application CN202010766386.2 discloses a four-roller lifting diamond wire cutting machine for stone, including a frame, diamond wire, wire rollers, a lifting device for lifting the stone, and a wire take-up and unwinding device. The diamond wire is wound around the wire rollers and connected to the wire take-up and unwinding device. The wire rollers include a first wire roller arranged horizontally, a second wire roller located above the first wire roller, a third wire roller, and a third... A fourth wire roller is positioned above the first wire roller. The first and second wire rollers are rotatably mounted on the frame. The third and fourth wire rollers are also rotatably mounted on the frame. Diamond wire is repeatedly wound around the first, second, third, and fourth wire rollers. The diamond wire forms a first mesh surface for cutting stone between the first and third wire rollers, and a second mesh surface between the second and fourth wire rollers. A receiving space for receiving stone is formed between the first and second mesh surfaces. The lifting device includes a support plate for supporting the stone and a lifting motor. However, the existing diamond wire stone cutting machine has the following problems during use: the mesh surface cannot be adjusted during cutting, resulting in poor flexibility and unsatisfactory cutting effect. In view of the above-mentioned problems, the inventors of this invention conducted in-depth research on these problems, leading to this invention. [Summary of the Invention]

[0004] The technical problem to be solved by the present invention is to provide an oscillating stone cutting machine, which solves the problems of existing stone cutting machines having no adjustable mesh surface during cutting, poor flexibility of use, and poor cutting effect.

[0005] The present invention is implemented as follows: a swing-type cutting machine includes a cutting unit, a frame, a lifting mechanism and a swing mechanism, wherein a diamond wire is wound on the cutting unit, and the diamond wire forms a cutting mesh surface at the bottom of the cutting unit;

[0006] The cutting unit is equipped with the swing mechanism on both sides. The two sides of the cutting unit refer to the two surfaces that the diamond wire does not pass through when the cutting unit is in operation. The middle part of the side of the cutting unit is rotatably connected to the swing mechanism, and the two ends of the side of the cutting unit are slidably connected to the swing mechanism. The swing mechanism drives the cutting unit to swing. The two ends of the side refer to the two ends along the horizontal direction.

[0007] Each of the swing mechanisms is provided with a lifting mechanism on the side opposite to the cutting unit. The lifting mechanism is mounted on the frame and drives the swing mechanism and the cutting unit to move up and down.

[0008] Furthermore, it also includes an auxiliary lifting mechanism, with each of the two swing mechanisms equipped with an auxiliary lifting mechanism; the auxiliary lifting mechanism is fixed on the frame, and the movable end of the auxiliary lifting mechanism is connected to the swing mechanism.

[0009] Furthermore, it also includes a stone conveying vehicle; the stone conveying vehicle is located below the cutting unit, and several supporting wooden strips are placed on the top of the stone conveying vehicle, and the supporting wooden strips are perpendicular to the diamond wire on the cutting mesh surface.

[0010] Furthermore, the swing mechanism includes a swing support, an arc-shaped slide rail assembly, and a swing drive assembly; the swing support is disposed on the lower side of the cutting unit, and the middle position of the lower side of the cutting unit is rotatably connected to the swing support via a pivot.

[0011] The swing support has two connecting arms. The two ends of the side of the cutting unit are provided with the arc-shaped slide rail assembly. Each connecting arm is connected to one arc-shaped slide rail assembly. Each connecting arm is provided with a swing drive assembly, and the swing drive assembly is connected to the arc-shaped slide rail assembly in a transmission connection. The swing drive assemblies on each connecting arm work synchronously, and the two swing drive assemblies on the same side rotate in the same direction.

[0012] Furthermore, the arc-shaped slide rail assembly includes an arc-shaped track and at least one connecting seat slidably connected to the arc-shaped track. The arc-shaped track is disposed on the cutting unit, and the connecting arm is fixedly connected to the connecting seat.

[0013] Furthermore, the swing drive assembly includes a first drive motor, a drive gear, and roller pins; an assembly groove is formed on the outer convex surface of the arc track along the swing direction, and a plurality of roller pins are installed rotatably and at equal intervals in the assembly groove; the first drive motor is fixed on the connecting arm, the drive gear is fixedly connected to the output end of the first drive motor, and the drive gear is meshed with the roller pins in the assembly groove for transmission.

[0014] Furthermore, the lifting mechanism includes a lead screw, a second drive motor, and a guide rail;

[0015] The swing mechanism has a nut seat fixed on the side away from the cutting unit, and the lead screw passes through the nut seat and is threadedly connected to the nut seat; the second drive motor is fixed on the frame, and the output end of the second drive motor is connected to one end of the lead screw;

[0016] The frame is provided with guide rails on both sides corresponding to the lead screw, and the swing mechanism is provided with sliders on both sides of the nut seat, and the sliders are slidably connected to the guide rails.

[0017] Furthermore, the cutting unit includes a main frame, a wire roller, a wire feeding mechanism, a wire take-up mechanism, and a third drive motor;

[0018] The main frame has four corners where the wire rollers are rotatably mounted, and each wire roller is connected to a third drive motor. The diamond wire is repeatedly wound around each wire roller and forms a cutting mesh at the bottom of the main frame. The wire feeding mechanism is located on the end face of one end of the main frame, and the wire take-up mechanism is located on the end face of the other end of the main frame. One end of the diamond wire is connected to the wire feeding mechanism, and the other end of the diamond wire is connected to the wire take-up mechanism.

[0019] Furthermore, the auxiliary lifting mechanism is a lifting cylinder.

[0020] By adopting the technical solution of the present invention, at least the following beneficial effects are achieved:

[0021] 1. By setting swing mechanisms on both sides of the cutting unit, the middle of the side of the cutting unit is rotatably connected to the swing mechanism, and the two ends of the side of the cutting unit are slidably connected to the swing mechanism. Simultaneously, the swing mechanism is connected to the frame via a lifting mechanism. This allows the cutting unit to swing to the desired position using the swing mechanism, forming the required cutting angle between the cutting mesh and the stone. Alternatively, the lifting mechanism can drive the swing mechanism and the cutting unit to move up and down together, allowing the cutting unit to move the cutting mesh downwards to press against the stone for cutting, or upwards to move away from the stone. Therefore, compared with existing diamond wire cutting machines for stone, this invention not only allows for adjustment of the cutting mesh according to actual cutting needs, improving flexibility, but also reduces the contact area between the cutting mesh and the stone when the cutting mesh forms a cutting angle by driving the cutting unit to swing, thereby improving cutting efficiency.

[0022] 2. Each swing mechanism is cleverly equipped with an auxiliary lifting mechanism, which is fixed to the frame. During operation, the auxiliary lifting mechanism can be used to hold the cutting unit and the swing mechanism in place. The force on the cutting unit and the swing mechanism can be transferred to the frame through the auxiliary lifting mechanism, instead of being entirely applied to the lifting mechanism. Therefore, damage to the lifting mechanism can be reduced, which helps to extend the service life of the lifting mechanism.

[0023] 3. The swing drive assembly is designed to include a first drive motor, a drive gear, and roller pins. Several roller pins are installed at equal intervals in the mounting groove of the arc track. During operation, the drive gear and roller pins can work together to drive the arc track to move. Since the vibration and noise generated when the drive gear and roller pins work together are relatively small, vibration and working noise can be reduced. [Attached Image Description]

Detailed Implementation Methods

[0047] To better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] It should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing these embodiments and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0049] Please see Figures 1 to 12 As shown in the preferred embodiment of the present invention, the oscillating cutting machine 100 includes a cutting unit 1, a frame 2, a lifting mechanism 3, and an oscillating mechanism 4. The cutting unit 1 is wound with diamond wire 11, and the diamond wire 11 forms a cutting mesh surface 111 at the bottom of the cutting unit. During operation, the cutting mesh surface 111 can be used to cut the stone. Because the diamond wire 11 is relatively thin, compared with existing cutting tools such as saw blades, saw bands, and beaded wire saws, the cutting kerf of the stone can be reduced, thereby avoiding waste and reducing dust generation, thus reducing pollution.

[0050] The two sides of the cutting unit 1 are equipped with the swing mechanism 4. The two sides of the cutting unit 1 refer to the two surfaces that the diamond wire 11 does not pass through when the cutting unit 1 is in operation. The middle part of the side of the cutting unit 1 is rotatably connected to the swing mechanism 4, and the two ends of the side of the cutting unit 1 are slidably connected to the swing mechanism 4. The swing mechanism 4 drives the cutting unit 1 to swing, so that the cutting mesh surface 111 of the cutting unit 1 can form the required cutting angle with the stone, thereby reducing the contact area between the cutting mesh surface 111 and the stone. The two ends of the side refer to the two ends along the horizontal direction.

[0051] Each of the swing mechanisms 4 is provided with a lifting mechanism 3 on the side opposite to the cutting unit 1. The lifting mechanism 3 is mounted on the frame 2 and drives the swing mechanism 4 and the cutting unit 1 to move up and down, so that the cutting unit 1 can drive the cutting mesh 111 to move downward to cut the stone or drive the cutting mesh 111 to move upward to leave the stone.

[0052] This invention provides a swing mechanism 4 on both sides of the cutting unit 1. The middle of the side of the cutting unit 1 is rotatably connected to the swing mechanism 4, and the two ends of the side of the cutting unit 1 are slidably connected to the swing mechanism 4. Simultaneously, the swing mechanism 4 is connected to the frame 2 via a lifting mechanism 3. This allows the cutting unit 1 to swing to the desired position using the swing mechanism 4, forming the required cutting angle between the cutting mesh surface 111 and the stone. Alternatively, the lifting mechanism 3 can drive the swing mechanism 4 and the cutting unit 1 to move up and down together, allowing the cutting unit 1 to move the cutting mesh surface 111 downwards to press against the stone for cutting, or upwards to move away from the stone. Therefore, compared with existing diamond wire cutting machines for stone, this invention not only allows for adjustment of the cutting mesh surface 111 according to actual cutting needs, improving flexibility, but also reduces the contact area between the cutting mesh surface 111 and the stone 200 when the swing mechanism 4 drives the cutting unit 1 to swing, thus improving cutting efficiency.

[0053] In some embodiments of the present invention, the swing-type cutting machine 100 further includes an auxiliary lifting mechanism 5, and each of the two swing mechanisms 4 is equipped with an auxiliary lifting mechanism 5; the auxiliary lifting mechanism 5 is fixed on the frame 2, and the movable end of the auxiliary lifting mechanism 5 is connected to the swing mechanism 4, so as to use the auxiliary lifting mechanism 5 to pull the swing mechanism 4 and the cutting unit 1.

[0054] Since the cutting unit 1 and the swing mechanism 4 in this invention are relatively heavy, in order to avoid the weight of the cutting unit 1 and the swing mechanism 4 being entirely applied to the lifting mechanism 3, this invention cleverly equips each swing mechanism 4 with an auxiliary lifting mechanism 5 and fixes the auxiliary lifting mechanism 5 to the frame 2. In actual operation, the auxiliary lifting mechanism 5 can be used to pull the cutting unit 1 and the swing mechanism 4, so that the force on the cutting unit 1 and the swing mechanism 4 can be transmitted to the frame 2 through the auxiliary lifting mechanism 5, instead of being entirely applied to the lifting mechanism 3. Therefore, it can reduce damage to the lifting mechanism 3 and help to improve the service life of the lifting mechanism 3.

[0055] In one specific embodiment of the present invention, the auxiliary lifting mechanism 5 is a lifting oil cylinder.

[0056] In some embodiments of the present invention, please refer to the following: Figure 3 and Figure 4 As shown, the oscillating cutting machine 100 also includes a stone conveyor 6, which is used to transport the stone to be cut. The stone conveyor 6 is located below the cutting unit 1, and several supporting wooden strips 61 are placed on top of the stone conveyor 6, with the supporting wooden strips 61 perpendicular to the diamond wires 11 on the cutting mesh 111. Since the cutting mesh 111 of the cutting unit 1 may come into contact with the stone conveyor 6 when cutting to the bottom of the stone, potentially causing the stone conveyor 6 to be cut, this invention employs supporting wooden strips 61 on top of the stone conveyor 6 and places the stone 200 on the supporting wooden strips 61. This ensures that when the cutting mesh 111 cuts to the bottom of the stone 200, it only contacts the supporting wooden strips 61 and not the stone conveyor 6, thus preventing damage to the stone conveyor 6. In addition, in a specific implementation of the present invention, the stone conveying vehicle 6 is also provided with railings 62 on both sides. The two sides of the stone conveying vehicle 6 refer to the two sides that are parallel to the diamond wire 11 on the cutting mesh surface 111, so as to use the railings 62 to limit the two sides of the stone and ensure that the cut stone 200 will not fall from the two sides.

[0057] In some embodiments of the present invention, the swing mechanism 4 includes a swing support 41, an arc-shaped slide rail assembly 42, and a swing drive assembly 43; the swing support 41 is disposed on the lower side of the cutting unit 1, and the middle position of the lower side of the cutting unit 1 is rotatably connected to the swing support 41 through a rotating shaft 44.

[0058] The swing support 41 has two connecting arms 411. Both ends of the side of the cutting unit 1 are provided with arc-shaped slide rail assemblies 42, and each connecting arm 411 is connected to one arc-shaped slide rail assembly 42. Each connecting arm 411 is provided with a swing drive assembly 43, and the swing drive assembly 43 is connected to the arc-shaped slide rail assembly 42 for transmission, so that the two ends of the cutting unit 1 can move along the arc-shaped trajectory of the arc-shaped slide rail assembly 42. The swing drive assemblies 43 on each connecting arm 411 work synchronously, and the two swing drive assemblies 43 on the same side rotate in the same direction, enabling each swing drive assembly 43 to drive the two ends of the cutting unit 1 to move synchronously. Simultaneously, the arc-shaped slide rail assemblies 42 are symmetrically arranged at both ends of the two sides of the cutting unit 1, and the inner concave surfaces of the two arc-shaped slide rail assemblies 42 on the same side face each other, allowing the two ends of the cutting unit 1 to move smoothly along the arc-shaped trajectory of the arc-shaped slide rail assembly 42.

[0059] This invention designs a swing mechanism 4 comprising a swing support 41, an arc-shaped slide rail assembly 42, and a swing drive assembly 43. The lower center of the side of the cutting unit 1 is rotatably connected to the swing support 41 via a pivot 44. The swing support 41 has two connecting arms 411, and arc-shaped slide rail assemblies 42 are provided at both ends of the two sides of the cutting unit 1. Each connecting arm 411 is connected to one arc-shaped slide rail assembly 42, and each arc-shaped slide rail assembly 42 is driveably connected to a swing drive assembly 43. This allows the swing drive assembly 43 to drive the cutting unit 1 during the stone cutting process. Both ends of the cutting unit 1 move along the arc-shaped trajectory of the arc-shaped slide rail assembly 42 to the desired position, so that the cutting mesh surface 111 of the cutting unit 1 can form the required cutting angle with the stone, thereby reducing the contact area between the cutting mesh surface 111 and the stone, and even making the cutting mesh surface 111 and the stone point contact, thus improving the cutting efficiency and making it more flexible to use; at the same time, arc-shaped slide rail assemblies 42 are provided at both ends of the two sides of the cutting unit 1, that is, a total of 4 arc-shaped slide rail assemblies 42 are provided. Each arc-shaped slide rail assembly 42 is connected to a connecting arm 411, which can ensure the stability of the swing of the cutting unit 1.

[0060] For more specific details, please refer to the following: Figure 9 and Figure 10 As shown, the arc-shaped slide rail assembly 42 includes an arc-shaped track 421 and at least one connecting seat 422 slidably connected to the arc-shaped track 421. The arc-shaped track 421 is disposed on the cutting unit 1, and the connecting arm 411 is fixedly connected to the connecting seat 422. Since the connecting seat 422 is slidably connected to the arc-shaped track 421, the connecting seat 422 is fixedly connected to the connecting arm 411, the arc-shaped track 421 is fixedly connected to the cutting unit 1, and the cutting unit 1 is rotatably connected to the swing support 41, the swing drive assembly 43 can drive both ends of the cutting unit 1 to move along the arc-shaped trajectory of the arc-shaped track 421, so that the cutting unit 1 can drive the cutting mesh surface 111 to swing and adjust.

[0061] For more specific details, please refer to the following: Figures 8-10As shown, the swing drive assembly 43 includes a first drive motor 431, a drive gear 432, and roller pins 433. An assembly groove 4211 is formed on the outer convex surface of the arc-shaped track 421 along the swing direction. A plurality of roller pins 433 are rotatably and evenly spaced within the assembly groove 4211. The first drive motor 431 is fixed to the connecting arm 411. The drive gear 432 is fixedly connected to the output end of the first drive motor 431, and the drive gear 432 is meshed with the roller pins 433 in the assembly groove 4211. In operation, the swing drive assembly 43 uses the first drive motor 431 to drive the drive gear 432 to rotate. During rotation, the drive gear 432 moves the arc-shaped track 421, thereby moving both ends of the cutting unit 1 to achieve adjustment.

[0062] The present invention designs a swing drive assembly 43 including a first drive motor 431, a drive gear 432 and roller pins 433, and installs several roller pins 433 at equal intervals in the mounting groove 4211 of the arc track 421. This allows the drive gear 432 to work with the roller pins 433 to drive the arc track 421 to move. Since the vibration and noise generated when the drive gear 432 and the roller pins 433 work together are relatively small, the vibration and working noise can be reduced.

[0063] More specifically, a limiting groove 4212 is formed on the inner concave surface of the arc-shaped track 421 along the swing direction. The connecting seat 422 is provided with a roller 45 that cooperates with the limiting groove 4212 and the assembly groove 4211 to achieve sliding. In a specific implementation of the present invention, since a rolling pin 433 is also provided in the assembly groove 4211, the roller 45 can abut against the outside of the rolling pin 433. The present invention, by designing the connecting seat 422 to have a roller 45 that cooperates with the limiting groove 4212 and the assembly groove 4211 to achieve sliding, can, on the one hand, use the roller 45 to limit the connecting seat 422, so that the connecting seat 422 will not detach from the arc-shaped track 421; on the other hand, the roller 45 can roll during use, which can ensure that the arc-shaped track 421 can drive the cutting unit 1 to swing more smoothly.

[0064] More specifically, the swing support 41 has a plate-like structure, and reinforcing ribs 412 are provided on both sides of the swing support 41. By designing the swing support 41 to have a plate-like structure, the overall structure can be made more compact and aesthetically pleasing; at the same time, providing reinforcing ribs 412 on both sides of the swing support 41 can effectively improve the support strength of the entire swing support 41.

[0065] For further details, please refer to the following: Figure 7As shown, the swing support 41 includes a main support plate 413, which has an inverted trapezoidal structure; the top two ends of the main support plate 413 extend upward to form the connecting arms 411. More specifically, to better meet the support requirements, it also includes a first support base 46 and an auxiliary support plate 47. The main support plate 413 is fixedly disposed at one end of the first support base 46, and the auxiliary support plate 47 is fixedly disposed at the other end of the first support base 46. Both the main support plate 413 and the auxiliary support plate 47 are rotatably connected to the rotating shaft 44 to better support the entire cutting unit 1.

[0066] In some embodiments of the present invention, please refer to the following: Figure 4 As shown, the lifting mechanism 3 includes a lead screw 31, a second drive motor 32, and a guide rail 33;

[0067] The swing mechanism 4 has a nut seat 34 fixed on the side away from the cutting unit 1. The lead screw 31 passes through the nut seat 34 and is threadedly connected to the nut seat 34. The second drive motor 32 is fixed on the frame 2, and the output end of the second drive motor 32 is connected to one end of the lead screw 31. During operation, the second drive motor 32 drives the lead screw 31 to rotate. During the rotation, the lead screw 31 can drive the nut seat 34 to move up and down. Since the nut seat 34 is fixedly connected to the swing mechanism 4, the nut seat 34 can drive the swing mechanism 4 and the cutting unit 1 to move up and down together. At the same time, since the swing mechanism 4 is equipped with an auxiliary lifting mechanism 5, it can avoid the weight of the swing mechanism 4 and the cutting unit 1 from being entirely applied to the lead screw 31, which helps to improve the service life of the lead screw 31.

[0068] The frame 2 has guide rails 33 arranged on both sides corresponding to the lead screw 31, and the swing mechanism 4 has sliders 35 fixed on both sides of the nut seat 34, with the sliders 35 slidably connected to the guide rails 33. By equipping the lead screw 31 and the nut seat 34 with sliders 35 and guide rails 33 respectively, the present invention enables better guidance of the swing mechanism 4 and the cutting unit 1 to rise and fall stably together through the sliding cooperation of the sliders 35 and guide rails 33.

[0069] In some embodiments of the present invention, please refer to the following: Figure 5 and Figure 6 As shown, the cutting unit 1 includes a main frame 12, a wire roller 13, a wire feeding mechanism 14, a wire take-up mechanism 15, and a third drive motor 16. The main frame 12 is a square frame.

[0070] The main frame 12 has four corners where the wire rollers 13 are rotatably mounted. Each wire roller 13 is connected to a third drive motor 16, which drives the wire roller 13 to rotate, ensuring that the diamond wire 11 can be transmitted more smoothly to achieve cutting. The diamond wire 11 is repeatedly wound around each wire roller 13 and forms the cutting mesh surface 111 at the bottom of the main frame 12. The wire feeding mechanism 14 is located on the end face of one end of the main frame 12, and the wire take-up mechanism 15 is located on the end face of the other end of the main frame 12. One end of the diamond wire 11 is connected to the wire feeding mechanism 14, and the other end of the diamond wire 11 is connected to the wire take-up mechanism 15.

[0071] In operation, the cutting unit 1 releases the diamond wire 11 wound on the wire release mechanism 14 and takes the diamond wire 11 back in through the wire take-up mechanism 15. At the same time, the third drive motor 16 drives each wire roller 13 to rotate, so that the diamond wire 11 on the cutting mesh surface 111 is continuously transmitted. Since the diamond wire 11 is repeatedly wound on the four wire rollers 13 and forms a cutting mesh surface 111 at the bottom of the main frame 12, the diamond wire 11 on the cutting mesh surface 111 can cut the stone during the wire release mechanism 14 and the wire take-up mechanism 15.

[0072] In some embodiments of the present invention, please refer to the following: Figures 2-4 as well as Figure 11 and Figure 12 As shown, the oscillating cutting machine 100 also includes a conveyor adjustment mechanism 7; the conveyor adjustment mechanism 7 includes a second support base 71, a fine-tuning platform 72, and a clamping assembly 73. The top of the fine-tuning platform 72 is provided with at least one pair of conveying tracks 74, which are perpendicular to the wire roller 13. The bottom of the stone conveyor 6 has traveling wheels 63 that cooperate with the conveying tracks 74, so that the stone conveyor 6 can carry the stone and move along the conveying tracks 74. It should be noted that the stone conveyor 6 can be equipped with a braking device (not shown), so that when the stone conveyor 6 carries the stone to the processing position, the braking device can be used to achieve the braking function, ensuring that the stone conveyor 6 will not move during the processing.

[0073] The top of the second support base 71 is provided with the clamping components 73 at both ends corresponding to the fine-tuning platform 72, so as to clamp the fine-tuning platform 72 from both ends using the clamping components 73; the top of the second support base 71 is provided with at least a pair of adjusting slide rails 75 between the clamping components 73 at both ends, the adjusting slide rails 75 are arranged parallel to each other with the wire roller 13, so that the fine-tuning platform 72 can drive the stone conveying vehicle 6 to move and adjust along the axial direction of the wire roller 13; the bottom of the fine-tuning platform 72 is slidably connected to the adjusting slide rails 75 through adjusting pulleys 76, and the two ends of the fine-tuning platform 72 are clamped by the clamping components 73. In practical use, when there is no need to adjust the position of the stone conveyor 6, the tightening component 73 can be used to tighten the fine-tuning platform 72 from both ends, preventing the fine-tuning platform 72 from moving along the adjusting slide rail 75. When the position of the stone conveyor 6 needs to be adjusted, the tightening component 73 is released, and the fine-tuning platform 72 is pushed to move along the adjusting slide rail 75, thereby moving the stone conveyor 6 and the stone to the required position. After the stone conveyor 6 and the stone have moved to the designated position, the tightening component 73 is used again to tighten the fine-tuning platform 72 from both ends, preventing the fine-tuning platform 72 from moving further.

[0074] The roller 13 is provided with a plurality of grooves 131 at equal intervals. In a specific implementation of the present invention, a portion of the grooves 131 can be used as main grooves and another portion of the grooves 131 can be used as spare grooves. The main grooves and spare grooves are alternately distributed on the roller 13. The diamond wire 11 is repeatedly wound around the main grooves of each roller 13 and forms the cutting mesh surface 111 at the bottom of the main frame 12.

[0075] Since the grooves 131 on the wire rollers 13 may be damaged during use, previously, when the grooves 131 on the wire rollers 13 were damaged, it was necessary to stop and replace the wire rollers 13. Replacing the wire rollers 13 was not only cumbersome, but also resulted in significant waste once damaged. Therefore, this invention designs a portion of the grooves 131 on each wire roller 13 as main grooves and another portion as spare grooves, with the main and spare grooves alternately distributed on the wire rollers 13. This allows the diamond wire 11 to be repeatedly wound around the main grooves of the four wire rollers 13, forming a cutting mesh surface 111 at the bottom of the main frame 12. Figure 2As shown, the stone is cut using the cutting mesh 111. Simultaneously, a conveyor adjustment mechanism 7 is provided, which can move the stone conveyor 6 along the axis of the wire rollers 13. This allows the diamond wire 11 to be repeatedly wound around the spare wire grooves of the four wire rollers 13 during the stone cutting process, forming a new cutting mesh 111 at the bottom of the main frame 12. The conveyor adjustment mechanism 7 then moves the stone conveyor 6 along the axis of the wire rollers 13. The new cutting mesh 111 is adjusted so that it corresponds to the saw cut on the stone on the stone conveyor 6, thus facilitating the continued cutting of the stone using the new cutting mesh 111. Therefore, by adopting the technical solution of the present invention, when the main wire groove is damaged and cannot be used, only the winding position of the diamond wire 11 and the position of the stone need to be simply adjusted to quickly resume cutting the stone without replacing the wire roller. The operation is simpler and more convenient, and the wire roller 13 can be reused by using the spare wire groove, avoiding waste.

[0076] More specifically, the tightening assembly 73 includes a tightening bolt 731 and a support block 732. The support block 732 is fixedly connected to the second support base 71, and the tightening bolt 731 passes through the support block 732 and is threadedly connected to it. An adjustment gap is provided between the support block 732 and the end of the fine-tuning platform 72, which can be designed according to actual usage needs. During use, when it is necessary to tighten the fine-tuning platform 72, the tightening bolt 731 needs to be rotated and moved closer to the fine-tuning platform 72 until it tightens the platform. Conversely, when it is necessary to loosen the fine-tuning platform 72, the tightening bolt 731 needs to be rotated and moved away from the platform.

[0077] More specifically, in order to better tighten the two ends of the fine-tuning platform 72, the top of the second support base 71 is provided with at least two tightening components 73 at both ends corresponding to the fine-tuning platform 72.
