Description

Technical Field

[0001] This invention relates to the field of stone cutting technology, specifically to a multi-line continuous stone cutting device and cutting method. Background Technology

[0002] Stone, as a high-end building decoration material, is widely used in interior and exterior decoration design, curtain wall decoration and public facility construction. For example, marble and granite are widely used to manufacture kitchen and bathroom countertops. After the stone is mined, it usually needs to be cut before it can be processed into building decoration materials.

[0003] For example, Chinese patent CN119305024A discloses a production line type diamond wire stone cutting machine. Through the wire feeding and take-up structure of servo motor 1 and winding roller 1 and servo motor 2 and winding roller 2 set on the top of the main frame, the diamond wire, together with several grooved rollers and connectors, can reciprocate to cut stone on the main frame. On the side of servo motor 1 and winding roller 1 and servo motor 2 and winding roller 2, a servo motor 3 drive adjustment wheel is fixedly set with two driven wheels to adjust the transmission tension of the diamond wire, thereby reducing the stress on the diamond wire in different directions, improving the durability of the diamond wire, and reducing the breakage rate.

[0004] However, most multi-wire stone cutting machines on the market currently use a four-main-roll rectangular wiring method, which has structural defects. The enclosed square space it forms significantly hinders the loading and unloading of stone, resulting in a long waiting time for the stone to be accurately positioned after each processing. This severely restricts the continuous operation of the equipment, leading to a significant decrease in overall production efficiency. In addition, they generally have a large footprint, which not only increases the space cost of the production workshop but also limits the flexible layout of the production line. Especially when space resources are scarce, this severely restricts the company's capacity expansion and production planning. Summary of the Invention

[0008] Furthermore, it also includes an adjustment assembly for adjusting the spacing between the wire sheave structures, wherein the adjustment assembly includes: an adjustment roller located inside the wire sheave roller; a second track groove formed along the axial direction of the adjustment roller, wherein one end of the second track groove has a second feeding groove with an inclined groove structure, and the second track groove has the same number of spacing adjustment grooves as the wire sheave structures along its axial direction; and a sliding buckle located on the inner ring of the wire sheave structure, which can transition along the second feeding groove and slide along the second track groove to the spacing adjustment groove.

[0009] Furthermore, the reel structure includes: a first semi-circular wheel; a second semi-circular wheel, the second semi-circular wheel being disposed on one side of the first semi-circular wheel and forming an openable and closable annular structure with the first semi-circular wheel via a pivot pin; a locking block, disposed at the other end of the first semi-circular wheel, and having a locking slot on its end face; a locking groove, disposed at the other end of the second semi-circular wheel, and having a locking buckle on one side therein, one end of the locking buckle being fixedly connected to a sliding buckle, so that when the sliding buckle slides along the inclined surface of the second feeding groove, it pushes the locking buckle into the locking slot, forming a self-locking state between the first semi-circular wheel and the second semi-circular wheel.

[0010] Furthermore, it also includes a first track groove opened on the wiring roller, and a first feeding groove flush with and opposite to the second feeding groove at one end of the first track groove, providing the clearance space required for the sliding buckle to slide along the second feeding groove to the second track groove.

[0012] Furthermore, it also includes a winding assembly for synchronously winding and unwinding the cutting wire, wherein the winding assembly includes: a support frame, the support frame being disposed at the top of the cutting frame; a first lead screw, the first lead screw being disposed on the support frame and having guide rods on both sides thereof, wherein the first lead screw has two sets of first slides along its axial direction, and the first slides are able to slide along the guide rods; a winding wheel, the winding wheel being disposed on one side of the first slides; and a tensioning wheel, the tensioning wheel being disposed on the other side of the first slides.

[0013] Furthermore, the first lead screw is divided by a center line, with positive and negative threads on both sides of the center line to drive the two sets of first slides to move in opposite directions.

Step 2: Pull the cutting wire out from one of the winding wheels and lay it along the two adjacent winding wheel structures. After the winding rollers rewind it, the cutting wire is wound back onto the two winding wheel structures in the next row. Then, in this way, the cutting wire is laid onto the winding wheel structures in sequence. After the laying is completed, the cutting wire is wound back onto another winding wheel. Step 3: Place the stone to be cut on one of the conveyor belts and adjust its cutting position using a railcar.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0025] The following is based on Figures 1-13 This invention describes a multi-line continuous stone cutting device and cutting method provided in embodiments of the present invention.

[0026] On the one hand, the present invention provides a multi-line continuous cutting device for stone; like Figure 1As shown, the multi-line continuous cutting equipment for stone includes a cutting frame 1 and two sets of wire rollers 4 located at the upper and lower ends of the cutting frame 1, respectively. The wire rollers 4 are provided with split-type wire wheel structures 5 along their axial direction, and winding rollers 3 are provided on one side of the wire rollers 4, so that the cutting wire 6 is wound on the wire wheel structure 5, and wound back by the winding roller 3, and wound on the next row of wire wheel structures 5. According to this winding state, a cutting wire row is formed. The stone is continuously cut by means of double-wire roller cutting, which effectively solves the space limitation of the cutting site and realizes the continuous conveying and precise cutting of stone in the processing process, thereby achieving a continuous production line processing mode with high efficiency.

[0027] like Figures 2-5 , Figures 8-11 As shown, to facilitate the installation of the wire reel structure 5 and enable self-locking during installation, the wire reel structure 5 includes a first semi-circular wheel 51 and a second semi-circular wheel 52 located on one side of the first semi-circular wheel 51. The second semi-circular wheel 52 and the first semi-circular wheel 51 are connected by a pivot pin 53 to form an openable and closable annular structure. The other end of the first semi-circular wheel 51 is provided with a locking block 57, and the other end of the second semi-circular wheel 52 is provided with a locking groove 58. Based on the relative rotation of the first semi-circular wheel 51 and the second semi-circular wheel 52, the first semi-circular wheel 51 and the second semi-circular wheel 52 are closed to each other, so that the locking block 57 is inserted into the locking groove 58, forming a complete annular structure. The ring is fitted onto the wire roller 4 and serves as a cutting guide wheel for the cutting wire 6.

[0028] As a further embodiment, the end face of the locking block 57 is provided with a locking slot 59, and a locking buckle 56 is provided on one side of the slot 58. One end of the locking buckle 56 is fixedly connected to the sliding buckle 54. Furthermore, an adjustment assembly is provided inside the wire feeding roller 4. The adjustment assembly includes an adjustment roller 18, and a second track groove 20 is provided axially on the adjustment roller 18. One end of the second track groove 20 is provided with a second feeding groove 19 with an inclined groove structure. When the first semi-circular wheel 51 and the second semi-circular wheel 52 close to each other, the sliding buckle 54 is engaged in the second feeding groove 19. By pushing the wire wheel structure 5 to rotate, the sliding buckle 54 slides along the inclined surface of the second feeding groove 19, converting the rotational force into a supporting force, and pushing the sliding... The locking buckle 56 at the other end of buckle 54 extends out and slides into the locking slot 59. When the sliding buckle 54 slides along the second feeding groove 19 into the second track groove 20, the locking buckle 56 engages in the locking slot 59, forming a self-locking state. This gives the thread wheel structure 5 a convenient self-locking characteristic when it is installed on the wire cutting roller 4. Furthermore, when the thread wheel structure 5 needs to be replaced due to wear of the cutting wire 6, simply reset the thread wheel structure 5 to one end of the second feeding groove 19. By reversing the thread wheel structure 5, under the elastic reset of the compression spring 55, the sliding buckle 54 retracts and resets along the second feeding groove 19, and the locking buckle 56 slides out of the locking slot 59, thus completing the self-unlocking and allowing for disassembly and replacement.

[0029] It should be noted that the wire roller 4 is provided with a first track groove 14, and a first feeding groove 13 is provided at one end of the first track groove 14, which is flush with and opposite to the second feeding groove 19. This provides the clearance space required for the sliding buckle 54 to slide along the first feeding groove 13 into the second feeding groove 19 and into the second track groove 20 when the wire wheel structure 5 is closed.

[0030] like Figures 4-7 As shown, to achieve equal spacing adjustment of the thread wheel structure 5, the adjustment assembly also includes spacing adjustment slots 21, the same number as the thread wheel structure 5, opened along the axial direction of the adjustment roller 18. These slots 21 are aligned with the second feeding slot 19, allowing the thread wheel structure 5 to self-lock onto the wiring roller 4. This pushes the thread wheel structure 5 to slide axially along the wiring roller 4, enabling the internal sliding buckle 54 to slide along the second feeding slot 19. The sliding buckle 54 is then aligned with the spacing adjustment slot 21. After the thread wheel structures 5 are sequentially arranged and installed, the adjustment roller 18 is rotated to make the spacing adjustment slot 21 contact the sliding buckle 54, converting the rotational force into a linear thrust. This pushes the thread wheel structure 5 to adjust the spacing along the wiring roller 4 at equal intervals, thus adapting to the cutting process of stones of different thicknesses. Specifically: One end of the wiring roller 4 is provided with a splined sleeve 15, and one end of the adjusting roller 18 is provided with a rotating shaft 22. A first knob 16 for driving the adjusting roller 18 to rotate is provided at one end of the rotating shaft 22. A second lead screw 24 is provided inside the rotating shaft 22. A second knob 17 is provided at one end of the second lead screw 24, and a second slide 25 is provided along its axial direction. The second slide 25 is fixedly connected to the splined teeth 23. When the second knob 17 drives the second lead screw 24 to rotate, it pushes the splined teeth 23 to engage or disengage with the splined sleeve 15. This is achieved in the wire-aligning wheel structure 5. When making equal spacing adjustments, first turn the second knob 17 to drive the second lead screw 24 to rotate, converting the rotational force into a horizontal thrust, which pushes the second slide table 25 to move along its axial direction, displacing the spline tooth 23 from the spline tooth sleeve 15, so that the adjusting roller 18 has the ability to rotate relative to the wiring roller 4. At this time, by turning the first knob 16, the adjusting roller 18 is driven to rotate. By utilizing the sliding combination of its spacing adjustment groove 21 and the sliding buckle 54, the rotational force is converted into a linear thrust, which pushes each wire wheel structure 5 to adjust at equal intervals along the wiring roller 4.

[0031] like Figure 1 , Figure 12As shown, to achieve the winding and unwinding of the cutting wire 6 during cutting, a winding assembly for synchronously winding and unwinding the cutting wire 6 is provided at the top of the cutting frame 1. The winding assembly includes a support frame 7 at the top of the cutting frame 1, a first lead screw 9 is provided on the support frame 7, and guide rods 8 are provided on both sides of the support frame 7. The first lead screw 9 has two sets of first slides 10 along its axial direction, and the first slides 10 can slide along the guide rods 8. The first lead screw 9 has positive and negative teeth on both sides of the center line to drive the two sets of first slides 10 to move in opposite directions. A third electric current is provided at one end of the first lead screw 9. The machine 28 is connected to the first lead screw 9 via the transmission belt 29. A winding wheel 11 is provided on one side of the first slide table 10, and a tensioning wheel 12 is provided on the other side of the first slide table 10. The first lead screw 9 is driven to rotate by the third motor 28 as the driving source. The positive and negative threads of the first slide table 10 drive the two sets of first slide tables 10 to slide relative to each other along the axial direction of the guide rod 8. The positions of the two sets of winding wheels 11 are adjusted so that they are close to the two ends of the wire roller 4, so that the cutting wire 6 can be fed from one set of wire roller structures 5 and wound up from the other set of wire roller structures 5.

[0032] It should be noted that the first slide 10 is equipped with a second motor 26 that drives the winding wheel 11 to rotate, and an electric push rod 27 that drives the tension wheel 12 to move up and down is also provided on the first slide 10. By driving the rotation of the winding wheel 11 through the second motor 26, the cutting wire 6 on the winding wheel 11 can be unloaded or wound. By driving the tension wheel 12 to move up and down through the electric push rod 27, the cutting tension of the cutting wire 6 can be adjusted.

[0033] like Figure 13 As shown, to achieve continuous stone cutting, railcars 30 are provided on both sides of the cutting line 6, and a conveyor belt 31 is provided above the railcars 30. By using the railcars 30 to transport the stone on the conveyor belt 31 to one side of the cutting line 6, the stone is transported to the cutting line 6 under the transmission of the conveyor belt 31. The rotation drive of the first motor 2 on the wire roller 4 is transmitted to the cutting line 6 through the wire wheel structure 5, which drives the cutting line 6 to operate and perform cutting work. After the cutting is completed, the cut stone is transported away synchronously by the transmission action of another set of conveyor belts 31, thus realizing the continuous stone cutting work.

[0034] On the other hand, the present invention also provides a multi-line continuous cutting method based on stone, comprising the following steps: Step 1: Through the drive adjustment of the adjustment component, the spacing of the pre-adjusted thread wheel structure 5 is adjusted to pre-adjust the spacing of the cutting line 6 to adapt to the cutting of stones of different thicknesses. Step 2: Pull the cutting wire 6 out from one of the winding wheels 11 and lay it along the two adjacent winding wheel structures 5. After being wound by the winding roller 3, the cutting wire 6 is wound back onto the two winding wheel structures 5 in the next row. Then, in this way, the cutting wire 6 is laid on the winding wheel structure 5 in sequence. After the laying is completed, the cutting wire 6 is wound back onto another winding wheel 11. Step 3: Place the stone to be cut on one of the conveyor belts 31, and adjust its cutting position using the railcar 30. Then, use the conveyor belt 31 to transport the stone to the cutting line 6 for the cutting process, and then transport the cut stone out along another conveyor belt 31.
