Description

Technical Field

[0001] The present invention relates to the field of cutting machinery, and particularly to a common roller for a wire saw and a string saw and a cutting assembly using the roller. Background Art

[0002] In the field of cutting machinery, wire saws and string saws, as two common cutting tools, are widely used in many industries such as stone mining, concrete demolition, and wood processing. As a key component in wire saw and string saw equipment, the roller plays an important role in supporting, guiding, and driving.

[0003] Traditional wire saw rollers and string saw rollers are often developed specifically for their respective sawing methods and saw blade characteristics. A wire saw usually uses a relatively thick steel wire rope, which bears a large tensile force during operation. Accordingly, the wire saw roller needs to have high strength and wear resistance to adapt to long-term heavy load operation; while a string saw generally uses a relatively thin metal wire, and has high requirements for the surface accuracy of the roller and the smooth operation of the string saw.

[0004] This results in the non-universality of existing wire saw rollers and string saw rollers. In some processing occasions where both wire saws and string saws are needed, enterprises have to equip two different types of roller equipment and corresponding maintenance tools and spare parts; this not only increases the equipment procurement cost and warehousing cost, but also makes the management and maintenance of the equipment more complex; moreover, when it is necessary to frequently switch between wire saws and string saws for operation, the process of replacing the roller is cumbersome and time-consuming, seriously affecting the production efficiency. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a common roller for a wire saw and a string saw and a cutting assembly using the roller. By integrating a wire groove and a rope groove, a single roller is adapted to a wire saw and a string saw, reducing the equipment replacement frequency and lowering the equipment cost and maintenance complexity.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: Provide a common roller for a wire saw and a string saw, including: a roller shaft and saw grooves, the saw grooves are arranged at intervals around the roller shaft on the outer circumferential surface of the roller shaft; The saw grooves include a wire groove for winding a wire saw and a rope groove for winding a string saw. The wire groove and the rope groove are arranged at intervals on the outer circumferential surface of the roller shaft. The widths of the wire groove and the rope groove are respectively set corresponding to the diameters of the wire saw and the string saw, and the width of the wire groove is smaller than the width of the rope groove.

[0007] It should be noted that by providing circumferentially arranged and spaced saw grooves on the outer circumferential surface of the roller shaft, the overall arrangement of the saw grooves is defined, providing a basic structure for the subsequent winding of wire saws and rope saws. The saw grooves are divided into wire grooves for winding wire saws and rope grooves for winding rope saws, and the two are spaced apart, with widths corresponding to the diameters of the wire saw and the rope saw respectively, enabling a single roller to be adapted to both wire saws and rope saws, reducing the equipment replacement frequency, and lowering the equipment cost and maintenance complexity. The width of the wire groove is smaller than that of the rope groove, which conforms to the actual situation of the different diameters of wire saws and rope saws, ensuring the adaptability and stability of different saws during winding. When used for rope saw cutting, the rope saw is wound around the roller, and the roller drives the rope saw to perform circular motion through the rotation of the driving device. The rope saw contacts the surface of the object to be cut and generates frictional force under the drive of the cutting power device, thereby achieving cutting. At this time, the roller plays a role in supporting and guiding the movement trajectory of the rope saw, ensuring that the rope saw cuts along a predetermined path. In the wire saw cutting mode, the wire saw passes through the wire groove on the roller, and both ends are connected to the corresponding wire winding and unwinding devices. The roller also provides the power and guidance for the wire saw to run through rotation. The wire saw reciprocates rapidly under the drive of the roller, and cuts the material using the sharp edge of the wire saw. The roller ensures the tension and cutting accuracy of the wire saw during the cutting process through precise transmission and positioning. This solution makes the roller versatile, capable of winding both wire saws and rope saws. Users do not need to prepare different rollers for different types of saws, reducing the usage cost and the difficulty of equipment management. Moreover, the design of the groove width matching the diameter of the cutting saw (narrow wire groove and wide rope groove) ensures that the saw blade is not easily offset or slip during winding, improving the cutting accuracy and operation safety.

[0008] Preferably, the width of the wire groove is 0.2 - 1.5 mm, and the width of the rope groove is 3 - 10 mm.

[0009] It should be noted that wire saws (such as diamond wire saws) are usually used for high-precision cutting (such as silicon wafers, optical glass), and their diameter ranges from 0.1 - 1 mm. The width of the wire groove is slightly larger than the diameter of the wire saw (0.2 - 1.5 mm), which not only reserves a tolerance space to avoid wire saw jamming due to processing errors, but also allows coolant or lubricant to flow in the wire groove, reducing frictional heat (for example, continuous cooling is required when cutting silicon wafers). The contact area between the side wall and the wire saw is moderate, which not only restricts lateral displacement but also does not increase excessive friction. The typical diameter of the rope saw (such as diamond rope saws for concrete cutting) is 2 - 8 mm, and the swing allowance of the rope saw (±1 - 2 mm) and thermal expansion compensation (the thermal expansion coefficient of steel is about 12×10⁻ 6 / °C, the expansion amount is about 0.6 mm when the temperature rises by 50 °C), the bottom of the groove is designed to be arc-shaped, reducing the contact stress by 40%-60% (such as from 200 MPa to 80 MPa). This solution clearly gives the specific size range of the wire groove width of 0.2-1 mm and the rope groove width of 3-10 mm, further refining the width parameters of the wire groove and the rope groove, making the roller more operable and standard in design and manufacturing. The standard size range is beneficial to the mass production and quality control of the roller. The manufacturer can manufacture it according to the unified standard, improving the production efficiency and the consistency of product quality.

[0010] Preferably, the wire groove and the rope groove are located on the same circular line of the roller shaft, and the wire groove is opened at the bottom of the rope groove.

[0011] It should be noted that it is stipulated that the wire groove and the rope groove are located on the same circular line of the roller shaft, and the wire groove is opened at the bottom of the rope groove, which determines the specific positional relationship between the wire groove and the rope groove in the circumferential direction of the roller shaft. This positional setting makes the roller more compact in structure, and at the same time facilitates the winding operation of the wire saw and the rope saw on the roller; moreover, setting the wire groove and the rope groove on the same circular line of the roller shaft and opening the wire groove at the bottom of the rope groove has many advantages: on the one hand, this layout makes the structure of the roller more compact, reasonably utilizes the space on the outer circumferential surface of the limited roller shaft, avoids the overall size of the roller being too large due to the unreasonable layout of the wire groove and the rope groove, and is beneficial to reducing the overall volume and weight of the cutting equipment, improving the space utilization rate and portability of the equipment; on the other hand, the setting of the same circular line ensures that whether it is the wire saw or the rope saw when wound on the roller, the distribution of the driving force and the guiding force on them during the rotation of the roller is more uniform, making the wire saw and the rope saw run more smoothly during the cutting operation, and further improving the cutting accuracy and stability.

[0012] Preferably, the wire grooves and the rope grooves are alternately and spacedly opened on the roller shaft, and at least one wire groove is provided between adjacent rope grooves.

[0013] It should be noted that the wire grooves and the rope grooves are alternately and spacedly opened on the roller shaft, and at least one wire groove is provided between adjacent rope grooves. This layout increases the distribution diversity and flexibility of the wire grooves and the rope grooves on the roller shaft. The winding areas of different saws are staggered on the roller shaft, making full use of the space in the length direction of the roller shaft; the alternately spaced setting enables flexible selection of the position and quantity of the wound wire saw or rope saw according to the actual cutting requirements when the length of the roller shaft is limited, improving the use flexibility and adaptability of the roller; and setting at least one wire groove between adjacent rope grooves avoids the over-concentration of wire grooves or rope grooves, ensures the uniformity of the force on the circumferential direction of the roller shaft, reduces the risk of roller damage caused by excessive local force, and extends the service life of the roller.

[0014] Preferably, the wire grooves and the rope grooves are arranged at intervals in different sections on the roller shaft, and the wire grooves are arranged at intervals on the wire saw section of the roller shaft, and the rope grooves are arranged at intervals on the rope saw section of the roller shaft.

[0015] It should be noted that by concentrating the wire grooves on a part of the interval of the roller shaft and the rope grooves on another part of the interval, the rope saw section and the wire saw section can be arranged alternately or each account for half, so that the space of the roller shaft can be effectively utilized, and at the same time the operation process is simplified; users can choose which part of the interval of the saw grooves to use according to needs without complex adjustment or reconfiguration, thus improving work efficiency; and wire saw and rope saw can also be used simultaneously for cutting to improve work efficiency.

[0016] Preferably, the roller shaft includes a rotating roller and a surface layer assembly, the surface layer assembly is wrapped on the outer circumferential surface of the rotating roller, and the saw grooves are opened on the surface layer assembly.

[0017] It should be noted that by opening the saw grooves on the surface layer assembly instead of directly on the rotating roller, a material more suitable for making the saw grooves can be selected as the surface layer assembly without affecting the overall structural strength. For example, high-strength wear-resistant alloys or composite materials can be used to manufacture the surface layer assembly, thus significantly improving its wear resistance and extending the overall service life of the roller. When the surface layer assembly is worn to a certain extent, this part can be replaced separately without replacing the entire roller shaft, reducing the maintenance cost, and the surface layer assembly can be customized according to the requirements of different types of saws (wire saw or rope saw) to achieve the best working effect. For example, for a wire saw that requires high-precision cutting, the surface layer assembly can have a very smooth and uniform surface to reduce frictional resistance and improve cutting accuracy; while for a rope saw that bears a large tension, the grip and stability can be enhanced by adjusting the hardness and texture of the surface layer assembly. Opening the saw grooves on the surface layer assembly can simplify the design of the rotating roller because complex processing of the rotating roller itself is not required; this can not only reduce the manufacturing difficulty but also reduce waste of raw materials, thus effectively controlling production costs. In addition, the standardized design of the rotating roller is also beneficial to mass production and quality control.

[0018] Preferably, the surface layer assembly includes a rubber layer and a wear-resistant layer, the saw grooves are opened on the wear-resistant layer, and the rubber layer covers the outer surface of the wear-resistant layer.

[0019] It should be noted that by directly opening the saw groove on the wear-resistant layer, it can ensure that the saw groove has high hardness and wear resistance, so as to be able to withstand the friction and wear generated by the wire saw or rope saw during operation. The wear-resistant layer is usually made of high-strength alloy, ceramic or other wear-resistant materials, which can effectively extend the service life of the roller and reduce the frequent replacement and maintenance caused by wear; the rubber layer covers the outer surface of the wear-resistant layer, which can not only increase the friction between the wire saw or rope saw, but also provide a certain buffering effect, reducing the impact of vibration on the cutting process. Especially under the conditions of high-speed operation or high-load operation, the rubber layer not only helps to keep the saw stable, prevent slipping or deviation, improve the cutting accuracy and efficiency, but also can absorb impact and vibration to a certain extent, reduce the noise level, and create a quieter and more comfortable working environment for the operator.

[0020] A cutting assembly includes the wire saw and rope saw universal roller described in any one of the above, a cutting frame, a roller frame, a wire winding and unwinding device and an adjusting device. The roller frame is arranged on the cutting frame, the rollers are respectively arranged on the roller frame correspondingly, and one end of each roller is in transmission connection with a driving device. The wire winding and unwinding devices are respectively arranged on the movable roller frame and the fixed roller frame correspondingly, and can wind and unwind the wire saw wound around the rollers. The roller frame includes a fixed roller frame and a movable roller frame. The fixed roller frame is fixedly arranged at one end of the cutting frame, and the movable roller frame is correspondingly arranged at the other end of the cutting frame through the adjusting device, and the distance between the movable roller frame and the fixed roller frame can be adjusted through the adjusting device.

[0021] It should be noted that the cutting frame is the support frame of the entire cutting assembly, usually welded or bolted by high-strength metal profiles to form a solid and stable structure. The roller frame is installed on the cutting frame, and is generally firmly connected to the cutting frame through bolts, sliders or other connection methods, and can be adjusted in position according to needs. It is usually composed of parts such as brackets and bearing seats. The rollers are installed on the bearing seats of the roller frame through bearings, and the rollers are driven to rotate by a driving device; the wire winding and unwinding devices are respectively arranged on the fixed roller frame and the movable roller frame correspondingly, and can precisely control the wire saw wound around the rollers; in this solution, by combining the fixed roller frame and the movable roller frame and the application of the universal roller, the cutting assembly can use either a wire saw or a rope saw for cutting, improving the versatility and applicability of the cutting assembly. Users can flexibly select the type of saw according to different cutting tasks. The design of adjustable distance between the movable roller frame and the fixed roller frame can adapt to wire saws or rope saws of different lengths and specifications, and at the same time, the tension of the saw can be adjusted according to the thickness of the cutting material and the cutting requirements to ensure the stability of the saw and the cutting effect during the cutting process.

[0022] Preferably, the adjusting device includes a driving motor, a transmission lead screw, and a sliding assembly. The driving motor and the transmission lead screw are arranged on the base of the cutting frame along the horizontal axis of the cutting frame, and the driving motor is in transmission connection with the transmission lead screw. The upper end of the moving roller frame is arranged on the cutting frame through the sliding assembly, and the lower end is arranged on the cutting frame through the cooperation of the lead screw nut and the transmission lead screw.

[0023] It should be noted that the driving motor can precisely control the rotation of the transmission lead screw, thereby realizing the fine adjustment of the position of the moving roller frame. By setting specific parameters (such as the moving distance) through the control system, the driving motor can accurately adjust the position of the moving roller frame to adapt to the cutting requirements of different sizes of materials; The sliding assembly usually consists of a guide rail and a slider. The guide rail is fixed on the cutting frame, and the slider is installed at the upper end of the moving roller frame. This design not only reduces friction but also improves the guiding accuracy of the moving roller frame, ensuring that it will not shift or get stuck during the adjustment process; By combining the driving motor, the transmission lead screw, and the sliding assembly, the operation of the adjusting device becomes more convenient and automated; Users can set specific parameters (such as the moving distance) through the control system, and the system will automatically complete the position adjustment of the moving roller frame without manual operation; This is particularly important for application scenarios that require frequent adjustment of cutting parameters, which can significantly improve work efficiency and reduce human error.

[0024] Preferably, the sliding assembly includes a guide plate, a sliding block, and a fixed seat. The guide plates are respectively arranged on the upper and lower sides of the cross beam of the cutting frame along the axial direction of the cross beam. An inverted T-shaped guide chute is formed on the guide plate. The sliding block is arranged in the corresponding guide chute in a T shape and can move along the axial direction of the guide chute. The sliding block is fixedly connected to both sides of the moving roller frame through the fixed seat.

[0025] It should be noted that the cooperation of the inverted T-shaped guide chute and the T-shaped sliding block can effectively limit the shaking and offset of the moving roller frame during movement, ensuring that the moving roller frame can only move smoothly along the axial direction of the cross beam of the cutting frame, improving the stability and accuracy of the adjusting device; Through the design of the sliding assembly integrating the guide plate, the sliding block, and the fixed seat, this solution not only realizes the precise and stable movement of the moving roller frame but also greatly improves the operation convenience and automation level of the entire cutting assembly; At the same time, this design enhances the reliability and durability of the system and is suitable for various complex working environments and cutting tasks; For enterprises, this means lower operating costs, higher production efficiency, and better product quality.

[0026] The beneficial effects of the present invention: A common roller for a wire saw and a band saw and a cutting assembly using the roller provided by the present invention divides the outer circumferential surface of the roller shaft into a wire groove for winding the wire saw and a rope groove for winding the band saw by providing circumferentially spaced saw grooves. The two are spaced apart and the widths respectively correspond to the diameters of the wire saw and the band saw, realizing a single roller adapted to the wire saw and the band saw. In processing occasions where both the band saw and the wire saw are required, enterprises do not need to be equipped with two sets of different types of roller equipment and corresponding maintenance tools and spare parts, thus significantly reducing the equipment procurement cost and storage cost. At the same time, the equipment management and maintenance are also more convenient; and a variety of cooperation methods between the wire groove and the rope groove are adopted to realize the flexible use of the roller in different cutting scenarios.

[0038] It should be noted that these drawings and text descriptions do not in any way limit the scope of the concept of the present invention, but illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Specific embodiments

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment 1 As Figures 1 - 3 shown, a universal roller for a wire saw and a band saw includes: a roller shaft 1 and a saw groove 2, and the saw groove 2 is arranged at intervals around the roller shaft 1 on the outer circumferential surface of the roller shaft 1; The saw groove 2 includes a wire groove 21 for winding a wire saw and a rope groove 22 for winding a band saw. The wire groove 21 and the rope groove 22 are arranged at intervals on the outer circumferential surface of the roller shaft 1. The widths of the wire groove 21 and the rope groove 22 are set corresponding to the diameters of the wire saw and the band saw respectively, and the width of the wire groove 21 is smaller than the width of the rope groove 22.

[0041] The width of the wire groove 21 is 0.6 mm, and the width of the rope groove 22 is 3 mm.

[0042] The wire groove 21 and the rope groove 22 are located on the same circular line of the roller shaft 1, and the wire groove 21 is opened at the bottom of the rope groove 22.

[0043] The roller shaft 1 includes a rotating roller 11 and a surface layer assembly 12. The surface layer assembly 12 is wrapped on the outer circumferential surface of the rotating roller 11, and the saw groove 2 is opened on the surface layer assembly 12.

[0044] The surface layer assembly 12 includes a rubber layer and a wear-resistant layer. The saw groove 2 is opened on the wear-resistant layer, and the rubber layer covers the outer surface of the wear-resistant layer.

[0045] The working principle and usage method of the universal roller for a wire saw and a band saw in this embodiment: The present embodiment provides a universal roller for rope saws and wire saws, the core part of which is a roller shaft 1, which is composed of a rotating roller 11 and a surface layer component 12. The rotating roller 11 is responsible for providing rotational power, and the surface layer component 12 is wrapped on the outer circumference of the rotating roller 11 for installing a saw groove 2; a saw groove 2 surrounding the roller shaft 1 is arranged on the surface layer component 12, and these saw grooves 2 are divided into a wire groove 21 and a rope groove 22, the wire groove 21 is used for winding the wire saw, and the rope groove 22 is used for winding the rope saw; the wire groove 21 has a width of 0.6 mm, and a 0.55 mm wire saw can be used, and the rope groove 22 has a width of 3 mm, and a 2 mm rope saw can be used. Such a design ensures The adaptability and stability of saw blades of different diameters during winding are improved; the narrow width of the wire groove 21 is suitable for high-precision cutting (such as silicon wafer cutting), while the wide width of the rope groove 22 is suitable for rope saws that withstand greater tension (such as cutting of concrete and stone); the layout of the wire groove 21 and the rope groove 22 makes the roller structure more compact and facilitates the winding operation of the wire saw and the rope saw; the surface layer component 12 is composed of a rubber layer and a wear-resistant layer, and the saw groove 2 is opened on the wear-resistant layer to ensure high wear resistance and anti-friction performance. The rubber layer covers the outer surface of the wear-resistant layer, providing additional buffering effect, reducing the impact of vibration on the cutting process, and at the same time increasing friction to prevent the saw blade from slipping.

[0046] When using, choose to use a wire saw or a rope saw according to the requirements of the cutting task. For example, high-precision cutting tasks (such as silicon wafer cutting) usually use a wire saw, while heavy-duty cutting tasks (such as concrete cutting) use a rope saw; if it is the first time to use or replace the saw blade, you need to first remove the original saw blade on the roller shaft 1, check whether the various parts of the roller are intact, especially whether the wear-resistant layer and rubber layer of the surface layer component 12 are damaged, and replace them in time if damaged; install the roller on the roller frame 4 of the cutting component, and ensure that one end of it is connected to the drive device 7; then adjust the distance between the mobile roller frame 42 and the fixed roller frame 41 according to the cutting requirements to adapt to wire saws or rope saws of different lengths and specifications; When a rope saw is used, the rope is introduced into the rope groove 22 of the roller, and then gradually put on the rollers arranged in a square shape along the rope groove 22, and ensure that the rope saw fits tightly in the rope groove 22 without twisting or loosening; after winding, the tension of the rope is adjusted by adjusting the distance between the rollers to make the rope saw reach a suitable working tension; if a wire saw is used, the wire is wound in the wire groove 21 of the roller according to a predetermined path, and it is noted that the wire saw should be kept in the center position of the wire groove 21 to avoid deviation, and then the two ends of the wire saw are respectively connected to the corresponding wire-retracting and releasing devices 5, and the wire-retracting and releasing devices 5 are adjusted to make the wire saw have appropriate tension to meet the cutting requirements.

[0047] Example 2 like Figure 4 and Figure 5As shown in the figure, a universal roller for a wire saw and a thread saw according to this embodiment includes a roller shaft 1 and a saw groove 2. The saw groove 2 is arranged at intervals around the roller shaft 1 on the outer circumferential surface of the roller shaft 1. The saw groove 2 includes a wire groove 21 for winding a thread saw and a rope groove 22 for winding a wire saw. The wire groove 21 and the rope groove 22 are arranged at intervals on the outer circumferential surface of the roller shaft 1. The widths of the wire groove 21 and the rope groove 22 are respectively set corresponding to the diameters of the thread saw and the wire saw, and the width of the wire groove 21 is smaller than the width of the rope groove 22.

[0048] The width of the wire groove 21 is 1 mm, and the width of the rope groove 22 is 5 mm.

[0049] The wire groove 21 and the rope groove 22 are alternately arranged at intervals on the roller shaft 1, and there is one wire groove 21 between adjacent rope grooves 22.

[0050] The roller shaft 1 includes a rotating roller 11 and a surface layer assembly 12. The surface layer assembly 12 is wrapped on the outer circumferential surface of the rotating roller 11, and the saw groove 2 is formed on the surface layer assembly 12.

[0051] The surface layer assembly 12 includes a rubber layer and a wear-resistant layer. The saw groove 2 is formed on the wear-resistant layer, and the rubber layer covers the outer surface of the wear-resistant layer.

[0052] Compared with Embodiment 1: For the universal roller for a wire saw and a thread saw provided in this embodiment, the width of the wire groove 21 is increased from 0.6 mm to 1 mm, which can accommodate wire saws with a larger diameter (such as a diamond wire saw with a diameter of 1 mm). This design improves the compatibility of the roller with wire saws of different specifications and is suitable for a wider range of cutting tasks. The width of the rope groove 22 is increased from 3 mm to 5 mm, significantly improving the adaptability to thicker wire saws. The larger width of the rope groove 22 can better adapt to the swing margin and thermal expansion compensation of the wire saw, ensuring the stability and reliability of the wire saw during winding. The wire groove 21 and the rope groove 22 are alternately arranged at intervals on the roller shaft 1, and there is one wire groove 21 between adjacent rope grooves 22. The alternating arrangement allows users to flexibly select the positions and quantities of winding the wire saw or the rope saw according to actual cutting needs. For example, when it is necessary to use both the wire saw and the rope saw for cutting simultaneously, different areas can be used for winding respectively, improving the flexibility and adaptability of the cutting assembly.

[0053] It should be noted that, based on this embodiment, according to the different widths between adjacent rope grooves 22, the number of wire grooves 21 between the rope grooves 22 can also be set to two or more.

[0054] Embodiment 3 Such as Figure 6 And Figure 7As shown in the figure, a common roller for a wire saw and a string saw in this embodiment includes a roller shaft 1 and a saw groove 2. The saw groove 2 is arranged at intervals around the roller shaft 1 on the outer circumferential surface of the roller shaft 1. The saw groove 2 includes a wire groove 21 for winding the wire saw and a string groove 22 for winding the string saw. The wire groove 21 and the string groove 22 are arranged at intervals on the outer circumferential surface of the roller shaft 1. The widths of the wire groove 21 and the string groove 22 are respectively set corresponding to the diameters of the wire saw and the string saw, and the width of the wire groove 21 is smaller than the width of the string groove 22.

[0055] The width of the wire groove 21 is 0.8 mm, and the width of the string groove 22 is 8 mm.

[0056] The wire groove 21 and the string groove 22 are arranged in intervals in different sections on the roller shaft 1. The wire groove 21 is arranged at intervals at one end of the roller shaft 1, and the string groove 22 is arranged at intervals at the other end of the roller shaft 1. And the intervals of the wire groove 21 and the string groove 22 each account for half of the roller shaft 1.

[0057] The roller shaft 1 includes a rotating roller 11 and a surface layer assembly 12. The surface layer assembly 12 is wrapped on the outer circumferential surface of the rotating roller 11, and the saw groove 2 is opened on the surface layer assembly 12.

[0058] The surface layer assembly 12 includes a rubber layer and a wear-resistant layer. The saw groove 2 is opened on the wear-resistant layer, and the rubber layer covers the outer surface of the wear-resistant layer.

[0059] Compared with Embodiment 1: For the common roller for a wire saw and a string saw provided in this embodiment, the wire groove 21 and the string groove 22 are respectively arranged at intervals at both ends of the roller shaft 1, that is, the wire groove 21 occupies half of the roller shaft 1, and the string groove 22 occupies the other half of the roller shaft 1. This design makes full use of the space in the length direction of the roller shaft 1, separates the winding areas of the wire saw and the string saw, and they do not interfere with each other; the wire saw and the string saw will not affect each other during winding, avoiding vibration or resonance phenomena caused by their being too close; users can flexibly select the positions and quantities of winding the wire saw or the string saw according to the actual cutting task requirements; for example, when wire sawing and string sawing need to be carried out simultaneously, different areas can be used for winding respectively, thereby improving the overall working efficiency of the cutting assembly.

[0060] Embodiment 4 As Figures 8 - 10As shown in the figure, a cutting assembly according to this embodiment includes a wire saw and a wire saw universal roller described in any of the above embodiments, a cutting frame 3, a roller frame 4, a wire winding and unwinding device 5, and an adjusting device 6. The roller frame 4 is arranged on the cutting frame 3. The rollers are respectively arranged on the roller frame 4, and one end of each roller is in transmission connection with a driving device 7. The wire winding and unwinding device 5 is respectively arranged on the moving roller frame 42 and the fixed roller frame 41, and can wind and unwind the wire saw wound around the rollers. The roller frame 4 includes a fixed roller frame 41 and a moving roller frame 42. The fixed roller frame 41 is fixedly arranged at one end of the cutting frame 3. The moving roller frame 42 is correspondingly arranged at the other end of the cutting frame 3 through the adjusting device 6, and the distance between the moving roller frame 42 and the fixed roller frame 41 can be adjusted through the adjusting device 6.

[0061] The adjusting device 6 includes a driving motor 61, a transmission lead screw 62, and a sliding assembly 8. The driving motor 61 and the transmission lead screw 62 are arranged on the base of the cutting frame 3 along the horizontal axis of the cutting frame 3, and the driving motor 61 is in transmission connection with the transmission lead screw 62. The upper end of the moving roller frame 42 is arranged on the cutting frame 3 through the sliding assembly 8, and the lower end is arranged on the cutting frame 3 through the cooperation of a lead screw nut and the transmission lead screw 62.

[0062] The sliding assembly 8 includes a guide plate 81, a sliding block 82, and a fixed seat 83. The guide plates 81 are respectively arranged on the upper and lower sides of the cross beam of the cutting frame 3 along the axis of the cross beam of the cutting frame 3. An inverted T-shaped guide chute is formed on the guide plate 81. The sliding block 82 is arranged in the corresponding guide chute in a T shape and can move axially along the guide chute. The sliding block 82 is fixedly connected to both sides of the moving roller frame 42 through the fixed seat 83.

[0063] The working principle and usage method of a cutting assembly according to this embodiment: A cutting assembly provided in this embodiment adopts the universal roller for rope saws and wire saws as described above, and wire grooves 21 for winding wire saws and rope grooves 22 for winding rope saws are arranged at intervals on the outer circumferential surface of the roller shaft 1. The design of these saw grooves 2 enables one roller to adapt to different types of sawing tools (wire saws or rope saws), thereby improving the versatility and flexibility of the equipment; the cutting assembly uses the cutting frame 3 as a stable support base, and the fixed roller frame 41 is firmly installed at one end of the cutting frame 3 to provide stable starting end support for the entire cutting system. The mobile roller frame 42 is installed at the other end of the cutting frame 3 through the adjustment device 6, and works in conjunction with the fixed roller frame 41; the universal roller is installed on the roller frame 4, and one end of the universal roller is connected to the driving device 7, which provides power for the rotation of the roller. When the driving device 7 is started, the roller starts to rotate, thereby driving the rope saw or wire saw wound thereon to perform cutting movement; the driving motor 61 in the adjustment device 6 is powered on, and the output shaft of the driving motor 61 is connected to the transmission screw 62, and the rotation of the driving motor 61 is converted into the rotation of the transmission screw 62. Since the lower end of the mobile roller frame 42 cooperates with the transmission screw 62 through the screw nut, according to the screw nut transmission principle, the rotation of the transmission screw 62 will cause the mobile roller frame 42 to be displaced along the horizontal axis of the cutting frame 3. At the same time, the upper end of the movable roller frame 42 is connected to the cutting frame 3 through the sliding assembly 8. The guide plate 81 in the sliding assembly 8 is axially arranged on the upper and lower sides of the beam along the crossbeam of the cutting frame 3. The inverted T-shaped guide groove on the guide plate 81 is tightly matched with the T-shaped sliding block 82. When the movable roller frame 42 moves under the drive of the transmission screw 62, the sliding block 82 moves axially in the guide groove, which not only ensures the smooth movement of the movable roller frame 42, but also plays a role of precise guiding, preventing the movable roller frame 42 from deflecting or shaking during the movement, thereby ensuring that the tension of the wire saw is always in a suitable state during the cutting process to meet the requirements of different cutting materials and processes.

[0064] When using, first check whether all parts of the cutting assembly are intact, including the cutting frame 3, roller frame 4, universal roller, wire-reeling device 5, adjustment device 6, etc., especially check whether the connection of key parts such as the guide plate 81, sliding block 82, transmission screw 62, and drive motor 61 is firm, and whether there are signs of damage or looseness; Then, according to the cutting task, select a suitable wire saw or string saw and correctly install it on the universal roller; if it is a wire saw, ensure that both ends of the wire saw are respectively connected to the wire winding and unwinding devices 5 on the moving roller frame 42 and the fixed roller frame 41, and preliminarily adjust the tension of the wire saw; if it is a string saw, directly wind the string saw around the corresponding roller through the string groove 22; and fixedly install the fixed roller frame 41 at one end of the cutting frame 3 to ensure firm installation without shaking; the moving roller frame 42 is installed at the other end of the cutting frame 3 through the adjusting device 6, connect the screw nut and the transmission screw 62, as well as the sliding assembly 8 and the guide plate 81; turn on the power supply of the driving motor 61 and perform debugging through the control device to test whether the movement of the moving roller frame 42 under the action of the adjusting device 6 is smooth, check whether the movement of the sliding block 82 in the guide chute is normal and whether there is any jamming phenomenon; at the same time, check whether the transmission connection between the driving device 7 and the roller is normal and whether the rotation of the roller is stable; Finally, start the driving device 7 to make the roller start to rotate, drive the wire saw or string saw to move for cutting. After cutting is completed, first stop the driving device 7 and the cutting power device (or the wire winding and unwinding device 5) to make the saw blade stop moving; loosen the connection of the saw blade to each device, carefully remove the saw blade, and properly store it; clean the debris, dust and other sundries on the cutting assembly, clean and maintain each component, especially lubricate the transmission screw 62 of the adjusting device 6, the sliding assembly 8, etc., to prepare for the next use.
