Description

Technical Field

[0001] This utility model relates to the field of stone cutting equipment, and in particular to a fine wire diameter stone cutting machine. Background Technology

[0002] With the continuous development of the stone processing industry, the market has placed higher demands on cutting efficiency, precision, and cost control, with customers paying particular attention to the utilization rate of raw stone blocks. Especially for luxury stones with unique patterns, due to their high price, each additional slab cut can bring significant profit growth to customers. Traditional diamond wire saws, widely used in stone cutting, consist of hollow diamond teeth, steel wire, and plastic. The steel wire passes through the hollow diamond teeth, arranged with a specific number of teeth per meter, and the remaining parts are fixed by injection molding. The outer diameter of the diamond teeth is approximately 5mm. This structure not only leads to high manufacturing costs but also significantly impacts the stone yield due to the 5mm wire diameter, making it difficult to meet the market's demand for efficient and precise cutting.

[0003] Wire sawing technology, as a major innovation in the stone industry, has garnered increasing attention in the stone cutting field due to its core advantage of extremely high stone yield. Currently, breakthroughs have been achieved in the diameter of annular electroplated diamond wire, reaching approximately 0.5mm. Compared to traditional diamond wire saws, this significantly improves the yield and offers greater potential for cost control. However, due to the small wire diameter, the tension control and stability of this fine-diameter cutting wire are relatively poor when using the drive wheel and tension wheel of a traditional cutting machine.

[0017] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0018] This utility model discloses a fine-diameter stone cutting machine that uses fine-diameter cutting wire. Through the cooperation of the drive wheel, driven wheel, auxiliary guide wheel, and tension wheel of the cutting wheel assembly, a circular arrangement is achieved. Compared to the simple use of a drive wheel and tension wheel in existing technologies, this design's cutting wheel assembly can be used with fine-diameter cutting wire. The addition of an auxiliary guide wheel ensures the tension of the cutting wire and improves its stability. During operation, the cutting wheel assembly drives the cutting wire to rotate, allowing it to cut the stone at the cutting position on the machine frame. During cutting, the stone transported to the cutting position on the machine frame is cut by the downward movement of the cutting wheel assembly. After cutting, the stone is transferred using a transfer device.

[0019] Please refer to Figure 1 and Figure 2 A fine-diameter stone cutting machine includes a cutting wire 3, a frame 1, and a cutting wheel assembly 2 mounted on the frame 1. The frame 1 is inverted U-shape, and a cutting position is formed at the U-shaped opening of the frame 1. The cutting wheel assembly 2 includes a drive wheel 21, an auxiliary guide wheel 22, a tension wheel 23, and a driven wheel 27. The drive wheel 21, the auxiliary guide wheel 22, and the tension wheel 23 are arranged sequentially from top to bottom along the outer contour of the frame 1 on one side of the cutting position. The driven wheel 27, the auxiliary guide wheel 22, and the tension wheel 23 are arranged sequentially from top to bottom along the outer contour of the frame 1 on the other side of the cutting position. The cutting wire 3 is sleeved on the outside of the cutting wheel assembly 2 to form a ring structure.

[0020] As can be seen from the above description, the beneficial effects of this utility model are as follows: Based on the fine wire diameter cutting wire 3 used, compared with the cooperation of the drive wheel 21 and tension wheel 23 in the prior art, this design improves the stability of the fine wire diameter cutting wire 3 by adding an auxiliary guide wheel 22 between the two, which facilitates the self-rotation adjustment of the cutting wire 3 and improves the situation that it is easy to shake and not stable under the conventional wheel set due to the small wire diameter.

[0021] Furthermore, such as Figure 1 As shown, the cutting wheel assembly 2 also includes positioning wheels 24. The positioning wheels 24 on both sides of the cutting position are respectively located on the side of the driving wheel 21 and the driven wheel 27 near the cutting position; the positioning wheels 24 can be adjusted up and down.

[0022] As described above, the height position of the cutting line 3 at the cutting position is determined by the positioning wheel 24. During the actual cutting process, the cutting line 3 will generate bowing. Different raw materials and different cutting processes will produce different bowing, which will cause the wrap angle between the cutting line 3 and the positioning wheel 24 to change. In order to ensure that the wrap angle of the positioning wheel 24 can run at the most suitable angle when cutting different raw materials, an up and down adjustment device for the positioning wheel 24 is added, which can adjust the wrap angle between the cutting line 3 and the positioning wheel 24 during cutting.

[0023] Furthermore, such as Figure 3 and Figure 4As shown, the drive wheel 21, driven wheel 27, auxiliary guide wheel 22 and tension wheel 23 all include a wheel disc 25 and a rubber strip 26. The rubber strip 26 is detachably arranged around the wheel disc 25 and contacts the cutting line 3.

[0024] As can be seen from the above description, the design of the cutting wheel assembly 2, which consists of a wheel 25 and a rubber strip 26, can reduce the wear of the thin wire diameter cutting wire 3 when it rotates on the cutting wheel assembly 2 through the cooperation of the rubber strip 26 and the cutting wire 3; at the same time, the rubber strip 26, as a vulnerable part, can be quickly replaced by being detachable.

[0025] Furthermore, such as Figure 1 As shown, the tensioning wheel 23 includes a plurality of first supports 231 and second supports 234 arranged at intervals along the thickness direction of the frame 1, and a first tensioning disc 232 and a second tensioning disc 235 rotatably arranged corresponding to the first supports 231 and the second supports 234. The first supports 231, the first tensioning disc 232 and the second supports 234 and the second tensioning disc 235 are symmetrically arranged on both sides of the corresponding cutting position. The first tensioning disc 232 and the second tensioning disc 235 are provided with tensioning wheel grooves 233 for arranging the cutting line 3. There is an installation interval between adjacent first tensioning discs 232 and adjacent second tensioning discs 235. The first tensioning disc 232 is arranged within the installation interval of the second tensioning disc 235.

[0026] As can be seen from the above description, the tension of the cutting line 3 is adjusted by the design of the tension wheel 23; the tension wheels 23 on both sides are designed to be arranged in the installation interval on opposite sides, which can make the machine body arrangement compact.

[0027] Furthermore, the first tensioning wheel 232 and the second tensioning wheel 235 are provided with a number corresponding to the number of turns of the cutting line 3.

[0028] As described above, each cutting line 3 on the tensioning wheel 23 is equipped with a corresponding tensioning disc, which allows each cutting line 3 to be independently tensioned and controlled, ensuring that the tension of each cutting line 3 is more stable and its performance is fully utilized.

[0029] Furthermore, such as Figure 4 As shown, the first tensioning wheel 232 and the second tensioning wheel 235 are provided with at least two tensioning wheel grooves 233.

[0030] As can be seen from the above description, by designing at least two tensioning wheel grooves 233, one tensioning wheel groove 233 can be used as the working wheel groove, while the other tensioning wheel groove 233 can be used as the replacement wheel groove. In this way, the replacement frequency of the tensioning wheel can be reduced by switching the tensioning wheel groove 233.

[0031] Furthermore, such as Figures 5 to 7As shown, the upper side of the frame 1 is provided with a platform structure, which includes a fixed platform 11 and a telescopic platform 12. The fixed platform 11 is located inside the frame 1, and the telescopic platform 12 is located above the fixed platform 11. The telescopic platform 12 includes a pedal 121, a first pulley 122, and a first slide rail 123. The pedal 121 is located above the cutting wheel assembly 2. The first slide rail 123 extends horizontally from one side of the frame 1 toward the cutting position above. The pedal 121 is provided with the first pulley 122, and the first pulley 122 slides in cooperation with the first slide rail 123.

[0032] As described above, the platform structure includes a telescopic platform 12 and a fixed platform 11 from top to bottom. The fixed platform 11 is located inside the frame 1 and is used for hanging and maintaining the cutting wheel assembly 2. The telescopic platform 12, located above the fixed platform 11, is used for cutting and replacing broken wires in the cutting wheel assembly 2. However, since it interferes with the operation of the cutting line 3 when extended, a telescopic design is required to retract it after the above adjustments are completed. The telescopic platform 12 achieves its telescopic movement through the cooperation of the pedal 121, the first pulley 122, and the first slide rail 123. The pedal 121 serves as a standing platform for the operator.

[0033] Furthermore, such as Figure 8 As shown, a protective cover 13 is provided on the upper side of the frame 1, and the protective cover 13 is slidably arranged along both sides of the frame 1.

[0034] As can be seen from the above description, the design of the protective cover 13 on the upper side of the frame 1 can achieve its protective function while preventing dust and impurities from spreading during the cutting operation; in addition, the sliding arrangement of the protective cover 13 allows for sliding and avoidance when maintenance of the cutting line 3 and the cutting wheel set 2 is required.

[0035] Furthermore, such as Figure 5 As shown, the frame 1 is provided with a second pulley 14, which includes a lifting bracket 141 and a pulley structure 142. The lifting bracket 141 is perpendicular to the upper side of the frame 1, and the pulley structure 142 is provided on the lifting bracket 141. The protective cover 13 is provided with a second slide rail 131, which slides in cooperation with the pulley structure 142.

[0036] As described above, the sliding arrangement of the protective cover 13 is achieved through the cooperation of the second slide rail 131 with the lifting bracket 141 and the pulley structure 142. The design of the lifting bracket 141 can place the pulley structure 142 and the second slide rail 131 at a certain height of the frame 1, thereby preventing dust from falling into the sliding structure during the cutting operation below and affecting its use.

[0037] Furthermore, such as Figure 9As shown, the frame 1 includes a machine base column 15, a mounting frame 16 and a tensioning structure 17. The front side of the machine base column 15 is provided with a mounting frame 16 for assembling the cutting wheel set 2, and the rear side of the machine base column 15 is provided with a tensioning structure 17 fixed to the ground.

[0038] As can be seen from the above description, after the mounting bracket 16 is arranged on the front side of the machine column 15, the overall structure can be stabilized by the tensioning structure 17 on the rear side of the machine column 15, thereby reducing the impact of shaking during equipment operation.

[0039] Example 1 like Figure 1 As shown, a fine-diameter stone cutting machine includes a frame 1, a cutting wheel set 2, and a cutting wire 3.

[0040] The frame 1 is inverted U-shaped, and the opening of the frame 1 forms a cutting position.

[0041] like Figure 1 and Figure 2 As shown, the cutting wheel assembly 2 includes a drive wheel 21, a driven wheel 27, an auxiliary guide wheel 22, a tension wheel 23, and a positioning wheel 24.

[0042] On one side of the cutting position, a positioning wheel 24, a drive wheel 21, an auxiliary guide wheel 22, and a tension wheel 23 are sequentially arranged along the U-shaped outline of the frame 1 from the bottom. The auxiliary guide wheel 22 and the tension wheel 23 are both located above the positioning wheel 24 and the drive wheel 21. The drive wheel 21 is located on the side of the positioning wheel 24, and the auxiliary guide wheel 22 is located on the side of the tension wheel 23. The positioning wheel 24 is adjustable in height along the frame 1.

[0043] On the other side of the cutting position, a positioning wheel 24, a driven wheel 27, an auxiliary guide wheel 22 and a tensioning wheel 23 are arranged sequentially along the U-shaped outline of the frame 1 from the bottom of the frame 1. The arrangement of the cutting wheel group 2 on the other side of the cutting position is only different from the arrangement of the drive wheel 21 and the driven wheel 27.

[0044] like Figure 3 and Figure 4 As shown, the aforementioned drive wheel 21, driven wheel 27, auxiliary guide wheel 22, tension wheel 23, and positioning wheel 24 all include a wheel disc 25 and a rubber strip 26. The rubber strip 26 is detachably arranged around the outer periphery of the wheel disc 25 and contacts the cutting line 3. Specifically, the wheel disc 25 has a groove along its circumferential surface, one side of the rubber strip 26 is engaged in the groove, and the other side has a groove that mates with the cutting line 3.

[0045] The above design, through the cooperation of the auxiliary guide wheel 22, avoids instability of the cutting wire 3 when used with the conventional cutting wheel set 2 due to excessively thin wire diameter. Furthermore, the lifting and adjusting design of the positioning wheel 24 matches the wrap angle between the cutting wire 3 and the positioning wheel 24, allowing for better adaptation to different raw material processing. The design of the rubber strip 26 prevents wear on the thin-diameter cutting wire 3 during the cutting process, and its detachable design allows for quick replacement if damaged.

[0046] Example 2 The difference between this embodiment and Embodiment 1 is that: like Figure 1 and Figure 2 As shown, the tensioning wheel 23 includes a plurality of first supports 231 and second supports 234 arranged at intervals along the thickness direction of the frame 1, and a first tensioning disc 232 and a second tensioning disc 235 rotatably arranged corresponding to the first supports 231 and the second supports 234. The first supports 231, the first tensioning disc 232 and the second supports 234 and the second tensioning disc 235 are symmetrically arranged on both sides of the corresponding cutting position. The first supports 231 and the second supports 234 are both connected to telescopic cylinders. The telescopic cylinders push the first supports 231 and the second supports 234 to move, thereby changing the tension of the cutting lines 3 on the first tensioning discs 232 and the second tensioning discs 235.

[0047] The first tensioning wheel 232 and the second tensioning wheel 235 are provided with tensioning wheel grooves 233 for arranging the cutting line 3. There are installation intervals between adjacent first tensioning wheel 232 and adjacent second tensioning wheel 235. The first tensioning wheel 232 is arranged within the installation interval of the second tensioning wheel 235.

[0048] By arranging the tensioning wheel 23 at the installation intervals on the opposite side, a compact arrangement of components is achieved.

[0049] like Figure 3 and Figure 4 As shown, the first tensioning disc 232 and the second tensioning disc 235 have a number corresponding to the number of turns of the cutting line 3, and each of the first tensioning disc 232 and the second tensioning disc 235 has three tensioning grooves 233. Through the one-to-one correspondence between the tensioning discs and each turn of the cutting line 3, independent tension control of each turn of the cutting line 3 can be achieved, ensuring stable cutting performance; and the design of multiple tensioning grooves 233 allows for interchangeable use, reducing the frequency of overall replacement.

[0050] Example 3 The difference between this embodiment and Embodiment 1 is that: like Figures 5 to 7 As shown, a platform structure is provided on the upper side of the frame 1, and the platform structure includes a fixed platform 11 and a telescopic platform 12.

[0051] like Figure 1 As shown, the fixed platform 11 is located inside the frame 1.

[0052] The telescopic platform 12 is located on the upper side of the fixed platform 11. The telescopic platform 12 includes a pedal 121, a first pulley 122 and a first slide rail 123. The pedal 121 is located above the cutting wheel assembly 2. The first slide rail 123 extends horizontally from one side of the frame 1 toward the cutting position. The pedal 121 is provided with the first pulley 122, and the first pulley 122 slides in cooperation with the first slide rail 123.

[0053] like Figure 6 and Figure 7 As shown, two first slide rails 123 are arranged in parallel. One first slide rail 123 has a rectangular cross-section along its length, while the other first slide rail 123 has a V-shaped cross-section along its length. Correspondingly, one first pulley 122 is a U-shaped roller, and the other first pulley 122 is a V-shaped roller. The V-shaped roller has high positioning accuracy, strong load-bearing capacity, and smooth operation. The U-shaped roller has good guiding properties, and the gap between it and the rail facilitates adjustment of the pedal 121 position. Furthermore, its larger contact area with the first slide rail 123 helps ensure the stability of the pedal 121 during movement. In terms of installation and maintenance, the internal structures of these two types of rollers are relatively simple, facilitating installation and disassembly, and reducing the maintenance cost and difficulty of the equipment.

[0054] like Figures 5 to 8 As shown, a protective cover 13 is provided on the upper side of the frame 1, covering the upper structure of the frame 1. The protective cover 13 is slidably arranged along both sides of the frame 1. Specifically, a second pulley 14 is provided on the frame 1. The second pulley 14 includes a lifting bracket 141 and a pulley structure 142. The lifting bracket 141 is perpendicular to the upper side of the frame 1, and the pulley structure 142 is provided on the lifting bracket 141. A second slide rail 131 is provided on the protective cover 13, and the second slide rail 131 is slidably engaged with the pulley structure 142. The protective cover 13 protects the frame 1 and prevents dust from spreading during the cutting process. The combination of the lifting bracket 141, the pulley structure 142, and the second slide rail 131 prevents dust from falling into the sliding structure during the cutting operation below and affecting its use.

[0055] Example 4 The difference between this embodiment and Embodiment 1 is that: like Figure 8 and Figure 9As shown, the frame 1 also includes a machine column 15, a mounting frame 16, and a tensioning structure 17. The front side of the machine column 15 is provided with a mounting frame 16 for assembling the cutting wheel assembly 2, and the rear side of the machine column 15 is provided with a tensioning structure 17 fixed to the ground. By fixing the tensioning structure 17 to the rear side of the machine column 15, the weight distribution on the machine column 15 can be balanced, improving the stability of the cutting wheel assembly 2 and the cutting line 3 on the mounting frame 16.

[0056] In summary, the fine-diameter stone cutting machine provided by this utility model, based on the use of fine-diameter cutting wire, improves the stability of the fine-diameter cutting wire by adding an auxiliary guide wheel between the two, compared to the existing technology's drive wheel and tension wheel combination. This facilitates the adjustment of the cutting wire's rotation and improves the situation where the wire diameter is too small and it is easy to shake and not stable under conventional wheel assembly.

[0057] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
