Description

Technical Field

[0001] The present application relates to the field of stone cutting, and in particular to a multi-saw blade marble cutting machine. Background Art

[0002] Circular band saw cutting machines have the advantages of being small and capable of cutting large pieces of stone. Therefore, they are widely used for cutting stone blocks into slabs (i.e., slab cutting). Existing circular band saw cutting machines all perform vertical cuts during cutting, so to prevent the cut slab from falling, a mechanical arm is required to secure the slab. Furthermore, in the prior art, due to the heavy weight of the stone and the fact that the slab is not separated from the block during cutting (the entire block is cut before the slab is separated from the block), the stone is placed directly on the cutting table during cutting without the need for a fixture. In some cases, the slab is cut with a single cut, completely separating it from the block with a single cut. Therefore, as the stone cutting process progresses, the weight of the stone remaining on the cutting table decreases, making it prone to shaking or shifting during subsequent cuts, significantly affecting the accuracy of the slab cutting.

For those skilled in the art of the present application, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0040] In the prior art, stone cutting machines are equipped with only one circular band saw, which can only cut one stone slab at a time, resulting in low cutting efficiency. In addition, the cut stone slabs are grabbed by a multi-jointed robotic arm, which is expensive to manufacture. Therefore, this application provides a multi-saw blade marble cutting machine to solve the technical problems of low cutting efficiency and high production cost of existing stone cutting machines.

[0041] See also Figures 1 to 5 , this embodiment provides a multi-saw blade marble cutting machine, including a cutting mechanism 1 and a stone slab supporting mechanism 2; the cutting mechanism 1 includes a machine base 12 and a cutting frame 11, the machine base 12 is provided with a stone placing table 14, the stone placing table 14 is used to place the stone 4, and the cutting frame 11 can move relative to the stone placing table 14 to cut and feed the stone 4; the stone slab supporting mechanism 2 is arranged on the side of the stone placing table 14, and can move with the cutting frame 11 to support the cut stone slab from the bottom; a cutting station and two or more annular cutting saw blades 13 are provided on the cutting frame 11, and the two or more annular cutting saw blades 13 cut the stone at the same time; a plurality of the cutting saw blades 13 are respectively arranged on the cutting wheel system, each of the cutting saw blades 13 is arranged in the vertical direction at the cutting station, and is arranged at intervals in the longitudinal direction, and the longitudinal direction is perpendicular to the cutting feed direction.

[0042] like Figure 1 and Figure 2 As shown, the cutting frame is a C-shaped frame, and the cutting station is located in the hollow part in the middle of the C-shaped frame, and the stone is cut at the cutting station. The machine base 12 is fixed, and the stone placement table 14 is set on the machine base 12. A roller 110 is provided at the bottom of the cutting frame 11, and the roller 110 is set on a transverse guide rail 111. The transverse guide rail 111 is set on the machine base 12 in the transverse direction, so that the cutting frame 11 and the annular cutting saw blade thereon can move in the transverse direction relative to the stone placement table. Among them, there are multiple cutting saw blades 13, which can cut multiple pieces of stone at the same time, and the distance between two adjacent cutting saw blades 13 is the thickness of the stone slab. The transverse direction refers to the cutting feed direction of the annular band saw.

[0043] The stone placing platform 14 is provided with a longitudinal moving device 141, a transverse abutting beam 142 and a longitudinal abutting beam 144. The longitudinal moving device 141 is used to drive the stone placing platform 14 and the stone thereon to move longitudinally, wherein the longitudinal direction refers to the direction perpendicular to the cutting feed direction. Figure 2 and Figure 3As shown, the transverse abutment beam 142 and the longitudinal abutment beam 144 are made of square hollow steel. These abutments contact the stone, defining its horizontal and vertical position. The transverse abutment beam is positioned parallel to the longitudinal direction on the side of the stone platform facing away from the cutting saw blade, while the longitudinal abutment beam 144 is positioned on the upper surface of the stone platform and perpendicular to the transverse abutment beam. The longitudinal movement device 141 may be a screw-nut drive mechanism, with screws and nuts positioned on either side of the stone platform, driving the platform longitudinally. When a stone is placed on the stone platform 14, the side of the stone facing away from the cutting saw blade abuts the transverse abutment beam 142, while the front end of the stone abuts the longitudinal abutment beam 144. Thus, the transverse abutment beam 142 and the longitudinal abutment beam 144 secure the stone's position on the stone platform 14.

[0044] During cutting, the cutting frame 11 is controlled to feed the stone along the transverse guide rail 111 to cut the stone. When a cutting process is completed, the cutting frame 11 is controlled to reset and move a certain distance (i.e., the thickness of multiple stone slabs) via the longitudinal movement device 141 before cutting again. Repeating the above steps can achieve cyclic cutting of stone slabs.

[0045] like Figure 2 and Figure 3 As shown, in this embodiment, a first sliding groove 1421 is provided on the transverse abutment beam 142 along the length direction, and one end of the longitudinal abutment beam 144 is slidingly connected to the first sliding groove 1421, so that the longitudinal abutment beam 144 can adjust its position along the first sliding groove 1421.

[0046] In this embodiment, by adjusting the position of the longitudinal abutting beam 144 , stones of different sizes can be fixed by the cooperation of the transverse abutting beam 142 and the longitudinal abutting beam 144 .

[0047] In some embodiments, in order to ensure the position of the longitudinal abutment beam 144 after adjustment and prevent the longitudinal abutment beam 144 from shifting, the longitudinal abutment beam 144 is provided with a locking mechanism, which is used to lock the position of the longitudinal abutment beam 144 after adjustment; the locking mechanism includes a locking bolt, which is provided at the end of the longitudinal abutment beam 144 extending into the first slide groove 1421.

[0048] In the above technical solution, the multi-saw blade marble cutting machine includes a cutting mechanism 1 and a slab support mechanism 2. The cutting mechanism 1 includes a machine base 12 and a cutting frame 11. The cutting frame is provided with a cutting station and two or more annular cutting saw blades 13. The two or more annular cutting saw blades 13 simultaneously cut the stone material 4. The multiple cutting saw blades are respectively mounted on a cutting gear train. Each cutting saw blade is arranged vertically at the cutting station and spaced longitudinally, with the longitudinal direction perpendicular to the cutting feed direction. The slab support mechanism is mounted on the side of the stone placement table and can move with the cutting frame to support the cut stone slab from the bottom. In the above technical solution, multiple cutting saw blades can be used to cut multiple pieces of stone simultaneously, greatly improving cutting efficiency. During the cutting process, the slab support mechanism can gradually extend from the bottom of the stone slab as the cutting feed is fed, thereby supporting multiple stone slabs simultaneously, thereby preventing the cut stone slabs from falling or falling over and being damaged. In addition, a transverse abutment beam and a longitudinal abutment beam are arranged on the stone placing table, which can prevent the stone from shaking and shifting during the cutting process, thereby improving the stone slab cutting accuracy and efficiency.

[0049] The cutting saw blade is made of an annular steel belt, and cutting teeth are provided on one side of the annular steel belt. In some embodiments, in order to improve cutting efficiency and reduce tooth wear, diamonds are welded to the tooth tips of the cutting teeth.

[0050] like Figure 4 As shown, in some embodiments, two or more cutting saw blades 13 are arranged in sequence along the cutting feed direction. That is, the positions of the cutting saw blades 13 in the cutting feed direction are not aligned side by side, but are staggered one by one in the cutting feed direction.

[0051] like Figure 4 As shown, in some embodiments, the cutting saw blades are four. In other embodiments, the cutting saw blades can also be two, three or five, etc.

[0052] like Figure 1 and Figure 5As shown, in some embodiments, the stone slab support mechanism 2 includes a plurality of support rollers 21 arranged horizontally and spaced apart. A second chute 143 is provided on the side of the stone placement platform 14, and the second chute 143 is provided along the direction of the cutting feed. One end of each support roller 21 is rotatably mounted on a support frame 22 via a bearing, and the other end of each support roller 21 is slidably and rotatably mounted within the second chute 143. The support frame 22 is connected to the cutting machine frame 11, and when the cutting machine frame cuts and feeds, the support rollers 21 are driven toward the bottom of the stone slab by the support frame 22. A ball bearing may be provided at one end of each support roller 21 extending into the second chute 143. The ball bearing may rotate within the second chute 143 and roll along the second chute 143, thereby allowing the support roller 21 connected to the ball bearing to roll and slide relative to the second chute 143.

[0053] In some embodiments, the plurality of support rollers 21 are divided into two or more support roller groups, each support roller group including two or more support rollers 21. The height of the support roller group located at the front end of the cutting feed is fixed and cannot be adjusted. The support roller group located at the rear end of the cutting feed is provided with a plurality of lifting cylinders 23 at the bottom thereof, and the height of the support roller group can be adjusted by the lifting cylinders 23. When cutting stone slabs, the height of the support roller group near the rear end of the cutting feed can be adjusted by the lifting cylinders 23 to provide sufficient support for the side of the stone slab away from the cutting saw blade.

[0054] In some embodiments, the cutting wheel system includes multiple groups of guide wheels, each group of guide wheels includes multiple guide wheels, and one group of guide wheels corresponds to one cutting saw blade 13; at least one guide wheel is a drive wheel, and multiple drive wheels are interconnected and connected to the same cutting drive motor.

[0055] In some embodiments, a plurality of lateral support columns 3 are provided along the cutting feed direction. Suction cups are provided at the tops of the support columns 3 for adsorbing and securing the stone slab. The bottoms of the support columns 3 can be secured to the machine base 12 by welding or bolting.

[0056] In some embodiments, the bottom of the lateral righting column 3 is fixedly mounted on the base 12, and the suction cup is connected to the lateral righting column 3 via a horizontally arranged adjustment shaft, so that the position of the suction cup is horizontally adjustable. The adjustment shaft can be connected to the lateral righting column 3 via a thread, and the position of the adjustment shaft and the suction cup can be adjusted by rotating the adjustment shaft to ensure that the suction cup adheres to the stone slab.

[0057] In some embodiments, the cutting frame is provided with a stabilizing device 131, which is used to limit the vibration of the cutting saw blade; the stabilizing device 131 includes an integrated stabilizing block provided above the cutting station, the integrated stabilizing block is provided with two or more limiting grooves, and the two or more cutting saw blades respectively pass through the corresponding limiting grooves. The integrated stabilizing block is provided with multiple limiting grooves,

[0058] The spacing between each limit groove is slightly larger than the thickness of the annular band saw. When the annular band saw is working normally, the inner wall of the limit groove in the integrated stabilizing block does not contact the annular band saw. However, when the annular band saw vibrates greatly, it contacts the inner wall of the limit groove of the integrated stabilizing block, thereby limiting the vibration amplitude of the annular band saw and preventing the annular band saw from breaking.

[0059] The upper stabilizer is provided with an adjustment component, and the adjustment component is used to adjust the position of the upper stabilizer. The adjustment component includes a lifting bracket adjustment cylinder. The integrated stabilizing block is provided on the lifting bracket. The lifting bracket can be vertically lifted and lowered on the adjustment fixing seat, and the adjustment fixing seat is fixedly installed on the cutting machine frame. The adjustment cylinder is connected to the lifting bracket and is used to drive the adjustment cylinder to lift and lower, thereby adjusting the height position of the integrated stabilizing block. When the vibration of the annular band saw is detected (the vibration can be detected by detecting the tension fluctuation of the annular band saw or the speed fluctuation of the annular band saw), the adjustment component adjusts the height position of the upper integrated stabilizing block in real time to actively reduce the amplitude of the annular band saw. When it is detected that the vibration of the annular band saw increases, the adjustment cylinder can be controlled to drive the downward adjustment, and the adjustment cylinder drives the integrated stabilizing block to descend, thereby improving the vibration suppression effect of the integrated stabilizing block.

[0060] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concepts of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
