Description

Technical Field

[0001] The invention relates to the technical field of saw band guide blocks, and in particular to a vertical sawing machine with a self-lubricating saw band guide block. Background Art

[0002] The guide block of a vertical sawing machine is an important component installed on the sawing machine to support and guide the operation of the saw band. The main function of the guide block is to ensure that the saw band remains stable when running at high speed, prevent the saw band from deflecting or bending, and thus ensure the accuracy and efficiency of cutting. The specific functions and effects include: Positioning and stabilizing the saw band: The guide blocks are located on both sides of the saw band and fit the saw band tightly. By providing lateral support, they prevent the saw band from lateral deflection or bending during operation. This function is essential to maintaining cutting accuracy, especially when dealing with hard materials or making fine cuts, stability has a direct impact on the cutting effect. Reduce wear: The guide block is usually made of wear-resistant material, and the surface in contact with the saw band is specially treated to reduce the friction between the saw band and the guide block, extending the service life of the saw band and the guide block. Prevent the saw band from derailing: When running at high speed, the saw band is prone to derailment or jumping due to uneven force. The guide block continuously and stably supports the saw band to keep it on the correct track at all times, thereby avoiding accidents and ensuring the safety of operation.

[0003] For example, the Chinese authorized patent "Band saw frame device with saw band adjustment function" with application number CN201810032700.7 aims to provide a band saw frame device that is not only convenient for operators to straighten the saw band, but also has good saw band straightening accuracy, thereby improving the service life and cutting accuracy of the saw band. It includes a saw frame; a saw band cutting mechanism; a saw band guiding mechanism, the saw band guiding mechanism includes a guide arm arranged on the saw frame, a saw band front guide block and a saw band rear guide block arranged on the guide arm, and a saw band front guide roller and a saw band rear guide roller arranged on the guide arm; and a saw band fine adjustment mechanism, the saw band fine adjustment mechanism includes a fixed seat arranged on the saw frame, a guide shaft rotatably arranged on the fixed seat, a locking nut arranged on the guide shaft for fixing the guide shaft, a saw band correction mechanism arranged on the guide shaft through a linear guide mechanism, and an adjustment execution device arranged on the fixed seat.

[0004] Although the above-mentioned prior art has certain progress and can improve the working accuracy of the saw band, it does not take into account the lubrication problem of the saw band guide block during operation.

[0005] In view of the above situation, in order to overcome the above technical problems, the present invention designs a vertical sawing machine with a self-lubricating saw band guide block to solve the above technical problems. Summary of the invention

[0006] The technical purpose to be achieved by the present invention is to design a vertical sawing machine with a self-lubricating saw belt guide block, so that the guide block can self-lubricate during the use of the vertical sawing machine, thereby improving work efficiency and reducing personnel expenses.

[0007] In order to achieve the above technical objectives, the present invention provides the following technical solutions:

[0008] A vertical sawing machine with a self-lubricating saw band guide block, the main components of which include a base, a workbench, a driving wheel, a support frame, a driven wheel and a flexible saw band. The workbench is firmly mounted on the base, providing a solid support foundation for operation; the driving wheel is located above the base, responsible for providing power to the saw band; the support frame is located on the side of the workbench, playing a supporting and stabilizing role; the driven wheel is installed above the driving wheel, and by cooperating with the driving wheel, the saw band can be operated efficiently. The flexible saw band is connected between the driving wheel and the driven wheel, and plays a key role in the cutting process. The vertical sawing machine is also specially equipped with a guide block mechanism, which is installed below the driven wheel. Its main function is to limit and straighten the flexible saw band through an adjustment component, so as to ensure that the saw band always remains in the best position during the cutting process to prevent deviation. The guide block mechanism is also equipped with a damping component, and the friction generated when the saw band is working can be effectively eliminated and transferred, which not only improves the stability of the sawing machine, but also reduces the wear of the equipment. The guide block mechanism has a built-in self-lubricating system. Through the linkage with the displacement of the flexible saw belt, the lubricating oil can be sprayed to the contact part between the saw belt and the guide block mechanism in time, thus realizing automatic lubrication. This design greatly reduces the frequency of manual maintenance and ensures the long-lasting performance of the equipment under high-intensity use. The design of the lubrication system makes full use of the movement characteristics of the saw belt itself, and fully automates the spraying and distribution of the lubricating oil, which reduces the friction resistance of the saw belt to a minimum, further improving the processing efficiency.

[0009] The guide block mechanism is composed of multiple precision components, including a guide mounting block, a rotating hole, a mounting column, an adjustment component, a rotating mechanism and a shock-absorbing component. Each part cooperates with each other to ensure the stability and accuracy of the equipment operation. The guide mounting block, as the basis of the entire guide block mechanism, is firmly mounted on the lower end of the upper part of the support frame, providing a reliable support and connection platform for other components. Rotation holes are provided on the two inner sides of the guide mounting block. These rotation holes provide the necessary space and fulcrum for the installation and operation of the adjustment component, allowing the adjustment component to rotate flexibly within a certain range, thereby achieving precise adjustment of the position and tension of the saw band. The mounting column is fixed to the side of the guide mounting block to connect and support the rotating mechanism. Through the mounting column, the rotating mechanism can be firmly positioned and kept stable, while having a certain degree of rotation flexibility to adapt to different working angles and requirements. A shock-absorbing component is installed inside the rotating mechanism. The shock-absorbing component absorbs and alleviates the vibration and impact generated during the operation of the machine, ensures the smooth operation of the entire guide block mechanism, reduces mechanical wear, and extends the service life of the equipment. The adjustment component is installed on the rotating hole and has the function of fine adjustment. The operator can fine-tune the position and tension of the saw belt by adjusting the components to ensure high precision and high efficiency during the cutting process. The precise coordination and synergy between the components enable the guide block mechanism to maintain excellent performance in complex working environments and meet various precision processing requirements. The overall design fully considers the stability of the structure, the practicality of the functions and the convenience of operation, providing a solid guarantee for the efficient operation of the equipment.

[0010] The rotating hole and the mounting column are arranged in a mirror image, and the distance between the two damping components is set to be greater than 10% of the thickness of the flexible saw band. The mirror-arranged rotating hole and the mounting column make the guide block mechanism structurally symmetrical. Such a symmetrical design can effectively balance the various stresses and loads generated by the saw band when it runs at high speed, and reduce the bias or lateral force caused by the asymmetric structure. This balance is particularly important for maintaining the straight line operation of the saw band, which helps to improve the accuracy and stability of cutting. The spacing of the damping components is set to be more than 10% larger than the thickness of the saw band, and such a spacing design provides appropriate buffer space. The saw band will inevitably produce slight vibrations and displacements during high-speed operation, and this spacing between the damping components can effectively absorb and alleviate these vibrations without excessively restricting the saw band. As a result, the saw band can run in a relatively loose but controlled state, without increasing friction due to too tight clamping, and avoiding uncontrolled vibrations caused by excessive spacing. The spacing is greater than 10% of the saw band thickness. In actual operation, this means that the damping assembly exerts less pressure on the saw band, which helps reduce direct friction contact between the saw band and the damping assembly, thereby reducing wear. This design extends the service life of the saw band and the damping assembly, and reduces the maintenance frequency and cost of the equipment. The mirror setting and appropriate buffer spacing give the equipment better adaptability and can more flexibly respond to different types of saw bands or different cutting requirements. For example, when using a thicker or harder saw band, this design ensures that the saw band will not be damaged due to excessive pressure, and conversely, when using a thinner saw band, there will be no large deflection or vibration due to insufficient support.

[0011] The adjustment assembly consists of key components such as the rotating pin, rotating plate and adjusting roller. The various parts are precisely connected and matched to achieve accurate adjustment of the saw band. First, the rotating pin, as the core connecting component of the adjustment assembly, is installed in the rotating hole of the guide block mechanism to ensure stable support and flexible rotation of the rotating plate. The rotating plate is fixed to the guide block mechanism through the rotating pin. Its unique design gives it good load-bearing capacity and adjustment flexibility.

[0012] The rotating plate adopts an H-shaped design. This structure not only enhances the strength and stability of the rotating plate, but also provides additional space for installing other components. There are empty slots at the upper and lower ends of the H-shaped rotating plate, which provide locations for the installation of the adjustment roller. The adjustment roller is located in the middle of the upper and lower slots of the rotating plate. Through its rolling characteristics, it can closely contact the surface of the saw belt and play a guiding and adjusting role during the operation of the saw belt.

[0013] The adjusting roller plays a vital role in the adjusting assembly. It can flexibly adjust the position and tension of the saw belt to ensure that the saw belt is in the best condition during high-speed operation. Through the rotation adjustment of the rotating pin, the rotating plate can rotate flexibly within a certain range, thereby driving the adjusting roller to apply appropriate force to the saw belt, so that the saw belt is always in the best working condition and avoids deviation or relaxation.

[0014] The combination of this series of precision components enables the adjustment components to be adjusted quickly and accurately during operation, greatly improving the working efficiency and cutting accuracy of the vertical sawing machine. At the same time, this design also simplifies the maintenance and adjustment process of the equipment, ensuring that the equipment can maintain stable performance during long-term and high-intensity use.

[0015] The rotating mechanism is composed of multiple precision components, including a rotating disk, a connecting block, a limiting slide groove, a sliding hole, a transition sleeve, an oil injection assembly, an oil injection sleeve, a sealing film and an oil outlet channel. These components work closely together to form a complete automatic lubrication system to ensure the smooth and efficient operation of the equipment. As the core component of the rotating mechanism, the rotating disk is firmly mounted on the mounting column, providing a rotating foundation for the entire system. A sliding hole is provided in the middle of the rotating disk, and this hole provides space for the installation and movement of the connecting block. The connecting block is fixed in the middle of the rotating disk, and limiting slide grooves are provided on both sides. The design of these slide grooves enables the connecting block to achieve a certain range of movement and adjustment inside the rotating disk, thus laying the foundation for the flexible operation of the system.

[0016] On the upper part of the rotating disk, a transition sleeve and an oil spray assembly are installed. These two components cooperate with each other to ensure that the lubricating oil can be accurately delivered to the saw belt and other parts that need lubrication. The transition sleeve plays a role of connection and transition, while the oil spray assembly is responsible for spraying the lubricating oil to the target part to ensure that the saw belt is always fully lubricated during high-speed operation. The oil injection sleeve is tightly installed on the rotating disk. Through the oil outlet channel inside it, the lubricating oil can flow from the oil injection sleeve into the rotating disk, and then be delivered to the parts that need lubrication through the oil outlet channel.

[0017] The sealing film is installed on the oil filling sleeve to seal and protect the oil from leakage or external contamination. This sealing design not only improves the efficiency of the lubrication system, but also extends the service life of the equipment.

[0018] The oil outlet channels are opened on the upper layer of the rotating disk. Through these channels, the lubricating oil can flow smoothly from the oil filling sleeve and be evenly distributed on the contact surface between the saw belt and the guide block through the rotating mechanism. In this way, the entire rotating mechanism can not only achieve precise mechanical movement during operation, but also automatically lubricate, reduce friction and wear, and improve the overall performance and durability of the equipment. This design greatly simplifies the maintenance process of the equipment while ensuring its reliability and efficiency under high-intensity working conditions.

[0019] The connecting blocks are arranged in a circular array, and the spacing angle between adjacent connecting blocks is set to 120°. The cross-sectional shape of the limiting slide is set to a square, and the limiting slide is arranged at the side center axis of the connecting block. The connecting blocks are spaced 120° in the circular array, forming a uniformly distributed triangular layout. This triangular array makes the force distribution of the entire rotating mechanism more balanced, avoiding structural deformation or damage caused by excessive force on a single point. Regardless of the angle at which the equipment operates, such a symmetrical design can ensure that the force borne by each connecting block is relatively uniform, which helps to improve the overall stability and durability of the rotating mechanism. The design of the circular array makes the layout of the connecting blocks very compact, making full use of the limited space of the rotating disk. The spacing angle of 120° ensures a reasonable distance between each connecting block, which will not interfere with each other and can effectively utilize the space. This compact and orderly layout makes the rotating mechanism more stable during operation and reduces errors caused by loose components or vibrations.

[0020] The cross section of the limit slide is square. This design ensures that the contact area between the slide and other components is maximized, thereby improving the stability and accuracy of the contact. The square cross section can effectively prevent the slide from lateral displacement or rotation during operation, ensuring that the connection block can still maintain accurate positioning when subjected to force.

[0021] The limit slide is located at the side center axis of the connecting block. This position design helps to maintain the balance of the connecting block. The slide at the center axis can better guide the linear motion of the connecting block during the sliding process to prevent it from deviating from the track. This arrangement not only makes the adjustment process smoother, but also can achieve higher adjustment accuracy.

[0022] The oil injection assembly consists of a mounting ring, a return spring, a control ball and a conduit block. The precise design between the various parts realizes a smooth lubricating oil delivery function. The mounting ring is fixed in the oil outlet channel to play a role of stable support. One end of the return spring is firmly clamped on the mounting ring, and the other end is connected to the control ball, which has the ability to rebound. The control ball accurately adjusts the flow of oil through the action of the spring to ensure the stability of lubrication. The conduit block is installed inside the oil filling sleeve. As the core part of the oil circuit, it is responsible for evenly distributing the lubricating oil to the parts that need lubrication, thereby ensuring the efficient operation of the entire system.

[0023] The confluence block is arranged radially, and the outer ends of the four confluence blocks are connected to each other, and the diameter of the cavity formed is the same as the inner diameter of the oil injection sleeve. The radial confluence block design allows the lubricating oil to be evenly distributed from the center to the surroundings, ensuring that the lubricating oil flows smoothly and evenly throughout the system. This uniform distribution is very important to ensure the consistency of the lubrication effect, and can avoid wear or overheating in certain areas due to insufficient lubrication.

[0024] The outer ends of the four confluence blocks are connected to each other, and the diameter of the cavity formed is the same as the inner diameter of the oil injection sleeve. This design makes full use of the space inside the oil injection sleeve and avoids unnecessary gaps and dead corners. This optimized space utilization not only improves the flow efficiency of the lubricating oil, but also reduces the possibility of oil stagnation in certain areas, ensuring the efficient operation of the lubrication system.

[0025] The conduit block fits perfectly with the inner diameter of the oil injection sleeve to form a tight sealing structure. In this way, when the system is running, it can effectively prevent the leakage of lubricating oil or external pollutants from entering the system, maintaining the purity of the lubricating oil and the operating stability of the system.

[0026] The shock-absorbing assembly consists of a shock-absorbing block, a limit slider, a shock-absorbing spring and a sliding block. Each component works together to effectively absorb and alleviate the vibration generated during the operation of the rotating mechanism, thereby improving the stability and durability of the equipment. First, the shock-absorbing block is firmly installed inside the rotating mechanism, playing a core role in support and buffering. The limit slider is closely set on both sides of the shock-absorbing block to provide additional lateral support for the shock-absorbing block to prevent it from offsetting or shaking during operation. The shock-absorbing spring is installed on the inner side of the shock-absorbing block, and absorbs the vibration energy during the operation of the equipment through its elasticity, thereby reducing the impact of vibration on the system. The sliding block is connected to the other end of the shock-absorbing spring to play the role of transmitting and adjusting force. The sliding block can only slide in a specially set sliding hole. This design limits the movement direction of the sliding block and ensures that it can only move along a specific trajectory, thereby further stabilizing the working effect of the shock-absorbing assembly and ensuring that the equipment can still remain stable when operating under high load.

[0027] The cross section of the shock absorbing block is set to be a fan ring, and the outer side thereof is coated with a wear-resistant material. The fan ring cross section design enables the shock absorbing block to form a larger contact area in the rotating mechanism. This design can provide a more uniform buffering and vibration absorption effect, so that the vibration and impact force can be better dispersed and alleviated, thereby improving the overall stability.

[0028] Coating the outer surface of the shock absorber with wear-resistant material can effectively resist wear and corrosion. This wear-resistant layer can significantly extend the service life of the shock absorber and reduce the need for frequent replacement and maintenance. The coating of wear-resistant material ensures that the shock absorber can maintain its performance and shape stability during long-term high-intensity operation.

[0029] The design of the fan-shaped ring section helps to better cooperate with other components and provide more stable support. This shape allows the shock absorber to be more firmly fixed in its position during operation, reducing component displacement or instability caused by vibration.

[0030] The fan-shaped design may also help evenly distribute the lubricant and effectively dissipate the heat. Under high load conditions, this shape can help dissipate the heat better and avoid material fatigue or performance degradation due to overheating.

[0031] The beneficial effects of the present invention are as follows:

[0032] 1. The present invention realizes self-lubrication and lubrication of the saw band by setting a guide block mechanism, and ensures that the lubricating oil is continuously and evenly supplied to the contact surface of the saw band and the guide block through the guide block mechanism. This continuous lubrication reduces the friction between the saw band and the guide block, reduces the risk of wear and overheating, and thus extends the service life of the saw band and the durability of the overall equipment. Good lubrication can also improve the cutting efficiency of the saw band and maintain stable cutting performance. The adjustment component allows instant adjustment of the position of the saw band to ensure that the saw band is always in the best working condition. This precise adjustment can effectively prevent the deviation or relaxation of the saw band and ensure accuracy and consistency during the cutting process. The stable saw band position helps to achieve more accurate and uniform cutting and reduces cutting errors caused by saw band deviation. The self-lubricating function reduces the dependence on manual lubrication and reduces the frequency and workload of equipment maintenance. The lubrication system automatically lubricates, which can maintain the normal operation of the equipment under long-term high-intensity working conditions, reducing equipment failures and downtime that may be caused by untimely maintenance.

[0033] 2. The continuous lubrication and timely adjustment functions of the present invention enable the saw belt to operate in the best condition, reducing the reduction in cutting efficiency caused by increased friction or improper position. This design enables the sawing machine to cut at a higher speed and efficiency, improves productivity, and reduces material waste. The good operation of the lubrication system can reduce the friction between the saw belt and the guide block, and reduce noise and vibration during operation. The stable operation state not only improves the comfort of the working environment, but also reduces the physical burden on the operator. The self-lubrication and timely adjustment functions achieved by setting the guide block mechanism can effectively improve the lubrication effect and cutting accuracy of the saw belt, reduce maintenance requirements, improve work efficiency, and reduce operating noise and vibration. This fully optimized design not only improves the overall performance and reliability of the sawing machine, but also brings higher production efficiency and better operating experience.

DETAILED DESCRIPTION

[0046] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0047] like Figure 1-9 As shown, a vertical sawing machine with a self-lubricating saw band guide block mainly comprises a base 1, a workbench 2, a driving wheel 3, a support frame 4, a driven wheel 5 and a flexible saw band 6. The workbench 2 is firmly mounted on the base 1, providing a solid support foundation for operation; the driving wheel 3 is located above the base 1, responsible for providing power for the saw band; the support frame 4 is located on the side of the workbench 2, playing a supporting and stabilizing role; the driven wheel 5 is installed above the driving wheel 3, and by cooperating with the driving wheel 3, the saw band can be operated efficiently. The flexible saw band 6 is connected between the driving wheel 3 and the driven wheel 5, and plays a key role in the cutting process. The vertical sawing machine is also specially equipped with a guide block mechanism 7, which is installed below the driven wheel 5. Its main function is to limit and straighten the flexible saw band 6 through the adjustment component 74, so as to ensure that the saw band always remains in the best position during the cutting process to prevent deviation. The guide block mechanism 7 is also equipped with a damping component 76, which can effectively eliminate and transfer the friction generated when the saw belt is working, which not only improves the stability of the sawing machine, but also reduces the wear of the equipment. The guide block mechanism 7 has a built-in self-lubricating system, which is linked with the displacement of the flexible saw belt 6 so that the lubricating oil can be sprayed to the contact part between the saw belt and the guide block mechanism 7 in time, thereby realizing automatic lubrication. This design greatly reduces the frequency of manual maintenance and ensures the long-term performance of the equipment under high-intensity use. The design of the lubrication system makes full use of the movement characteristics of the saw belt itself, and fully automates the spraying and distribution of the lubricating oil, so that the friction resistance of the saw belt is reduced to a minimum, further improving the processing efficiency.

[0048] The guide block mechanism 7 is composed of a plurality of precision components, including a guide mounting block 71, a rotation hole 72, a mounting column 73, an adjustment component 74, a rotating mechanism 75 and a shock absorbing component 76, and each part cooperates with each other to ensure the stability and accuracy of the operation of the equipment. The guide mounting block 71, as the basis of the entire guide block mechanism 7, is firmly mounted on the lower end of the upper part of the support frame 4, providing a reliable support and connection platform for other components. Rotation holes 72 are provided on the two inner sides of the guide mounting block 71, which provide the necessary space and fulcrum for the installation and operation of the adjustment component 74, allowing the adjustment component 74 to rotate flexibly within a certain range, thereby realizing the precise adjustment of the position and tension of the saw band. The mounting column 73 is fixed to the side of the guide mounting block 71, and serves to connect and support the rotating mechanism 75. Through the mounting column 73, the rotating mechanism 75 can be firmly positioned and kept stable, while having a certain degree of rotation flexibility to adapt to different working angles and requirements. A shock absorbing component 76 is installed inside the rotating mechanism 75. The shock absorbing component 76 absorbs and alleviates the vibration and impact generated during the operation of the machine, thereby ensuring the smooth operation of the entire guide block mechanism 7, reducing mechanical wear and extending the service life of the equipment. The adjustment component 74 is installed on the rotating hole 72 and has the function of fine adjustment. The operator can fine-tune the position and tension of the saw belt through the adjustment component 74 to ensure high precision and high efficiency during the cutting process. The precise coordination and synergy between the components enable the guide block mechanism 7 to maintain excellent performance in a complex working environment and meet various precision processing requirements. The overall design fully considers the stability of the structure, the practicality of the function and the convenience of operation, providing a solid guarantee for the efficient operation of the equipment.

[0049] like Figure 2-3As shown, the rotating hole 72 and the mounting column 73 are mirror-imaged, and the distance between the two damping components 76 is set to be greater than 10% of the thickness of the flexible saw belt 6. The mirror-imaged rotating hole 72 and the mounting column 73 make the guide block mechanism 7 structurally symmetrical. Such a symmetrical design can effectively balance the various stresses and loads generated by the saw belt when it is running at high speed, and reduce the bias or lateral force caused by the asymmetric structure. This balance is particularly important for maintaining the straight-line operation of the saw belt, which helps to improve the accuracy and stability of cutting. The spacing of the damping components 76 is set to be greater than 10% of the thickness of the saw belt, and such a spacing design provides appropriate buffer space. The saw belt will inevitably produce slight vibrations and displacements during high-speed operation, and this spacing between the damping components 76 can effectively absorb and alleviate these vibrations without excessively restricting the saw belt. As a result, the saw belt can run in a relatively loose but controlled state, without increasing friction due to too tight clamping, and avoiding uncontrolled vibrations caused by excessive spacing. The spacing is greater than 10% of the thickness of the saw band. In actual operation, it means that the damping assembly 76 exerts less pressure on the saw band, which helps to reduce the direct friction contact between the saw band and the damping assembly 76, thereby reducing wear. Such a design extends the service life of the saw band and the damping assembly 76, and reduces the maintenance frequency and cost of the equipment. The mirror setting and appropriate buffer spacing give the equipment better adaptability and can more flexibly cope with different types of saw bands or different cutting requirements. For example, when using a thicker or harder saw band, this design ensures that the saw band will not be damaged due to excessive pressure, and conversely, when using a thinner saw band, there will be no large deflection or vibration due to insufficient support.

[0050] like Figure 4 As shown, the adjustment assembly 74 is composed of key components such as a rotating pin 741, a rotating plate 742 and an adjusting roller 743. The various components are precisely connected and matched to achieve accurate adjustment of the saw band. First, the rotating pin 741, as the core connecting component of the adjustment assembly 74, is installed in the rotating hole 72 of the guide block mechanism 7 to ensure stable support and flexible rotation of the rotating plate 742. The rotating plate 742 is fixed to the guide block mechanism 7 by the rotating pin 741. Its unique design enables it to have good load-bearing capacity and adjustment flexibility.

[0051] The rotating plate 742 is designed in an H shape. This structure not only enhances the strength and stability of the rotating plate 742, but also provides additional space for installing other components. The upper and lower ends of the H-shaped rotating plate 742 are each provided with an empty slot, which provides a position for the installation of the adjustment roller 743. The adjustment roller 743 is located in the middle of the upper and lower empty slots of the rotating plate 742. Through its rolling characteristics, it can be in close contact with the surface of the saw belt and play a role in guiding and adjusting the saw belt during operation.

[0052] The adjusting roller 743 plays a vital role in the adjusting assembly 74. It can flexibly adjust the position and tension of the saw belt to ensure that the saw belt is in the best condition during high-speed operation. Through the rotation adjustment of the rotating pin 741, the rotating plate 742 can rotate flexibly within a certain range, thereby driving the adjusting roller 743 to apply appropriate force to the saw belt, so that the saw belt is always in the best working condition and avoids deviation or relaxation.

[0053] The combination of this series of precision components enables the adjustment component 74 to achieve fast and precise adjustment during operation, greatly improving the working efficiency and cutting accuracy of the vertical sawing machine. At the same time, this design also simplifies the maintenance and adjustment process of the equipment, ensuring that the equipment can maintain stable performance during long-term and intensive use.

[0054] like Figure 5-7 As shown, the rotating mechanism 75 is composed of a plurality of precision components, including a rotating disk 751, a connecting block 752, a limiting slide groove 753, a sliding hole 754, a transition sleeve 755, an oil injection assembly 756, an oil injection sleeve 757, a sealing film 758 and an oil outlet channel 759. These components cooperate closely to form a complete automatic lubrication system to ensure the smooth and efficient operation of the equipment. The rotating disk 751, as the core component of the rotating mechanism 75, is firmly mounted on the mounting column 73, providing a rotating foundation for the entire system. A sliding hole 754 is provided in the middle of the rotating disk 751, and this hole position provides space for the installation and movement of the connecting block 752. The connecting block 752 is fixed in the middle of the rotating disk 751, and limited slide grooves 753 are provided on both sides. The design of these slide grooves enables the connecting block 752 to achieve a certain range of movement and adjustment inside the rotating disk 751, thereby laying a foundation for the flexible operation of the system.

[0055] A transition sleeve 755 and an oil spray assembly 756 are installed on the upper part of the rotating disk 751. The two assemblies cooperate with each other to ensure that the lubricating oil can be accurately delivered to the saw belt and other parts that need lubrication. The transition sleeve 755 plays a role of connection and transition, while the oil spray assembly 756 is responsible for spraying the lubricating oil to the target part to ensure that the saw belt is always fully lubricated during high-speed operation. The oil injection sleeve 757 is tightly installed on the rotating disk 751. Through the oil outlet channel 759 inside it, the lubricating oil can flow from the oil injection sleeve 757 into the rotating disk 751, and then be delivered to the parts that need lubrication through the oil outlet channel 759.

[0056] The sealing film 758 is installed on the oil filling sleeve 757 to play a role of sealing and protection to prevent the lubricating oil from leaking or being contaminated by the outside. This sealing design not only improves the efficiency of the lubrication system, but also extends the service life of the equipment.

[0057] The oil outlet channels 759 are provided on the upper layer of the rotating disk 751. Through these channels, the lubricating oil can smoothly flow out from the oil filling sleeve 757 and be evenly distributed on the contact surface between the saw belt and the guide block through the rotating mechanism 75. In this way, the entire rotating mechanism 75 can not only achieve precise mechanical movement during operation, but also automatically lubricate, reduce friction and wear, and improve the overall performance and durability of the equipment. This design greatly simplifies the maintenance process of the equipment, while ensuring its reliability and efficiency under high-intensity working conditions.

[0058] The connecting blocks 752 are arranged in a circular array, and the interval angle between adjacent connecting blocks 752 is set to 120°. The cross-sectional shape of the limiting slide 753 is set to a square, and the limiting slide 753 is arranged at the side center axis of the connecting block 752. The connecting blocks 752 are spaced 120° in the circular array, forming a uniformly distributed triangular layout. This triangular array makes the force distribution of the entire rotating mechanism 75 more balanced, avoiding structural deformation or damage caused by excessive force on a single point. Regardless of the angle at which the device operates, such a symmetrical design can ensure that the force borne by each connecting block 752 is relatively uniform, which helps to improve the overall stability and durability of the rotating mechanism 75. The design of the circular array makes the layout of the connecting blocks 752 very compact, making full use of the limited space of the rotating disk. The interval angle of 120° ensures a reasonable distance between each connecting block 752, which will not interfere with each other and can effectively utilize the space. This compact and orderly layout makes the rotating mechanism 75 more stable during operation and reduces errors caused by loose components or vibrations.

[0059] The cross section of the limiting slide 753 is a square, and this design ensures that the contact area between the slide and other components is maximized, thereby improving the stability and accuracy of the contact. The square cross section can effectively prevent the slide from lateral displacement or rotation during operation, ensuring that the connecting block 752 can still maintain accurate positioning when subjected to force.

[0060] The limiting slide groove 753 is located at the central axis of the side of the connecting block 752. This position design helps to maintain the balance of the connecting block 752. The slide groove at the central axis can better guide the linear motion of the connecting block 752 during the sliding process to prevent deviation from the track. Such an arrangement not only makes the adjustment process smoother, but also can achieve higher adjustment accuracy.

[0061] like Figure 8As shown, the oil injection assembly 756 is composed of a mounting ring 7561, a return spring 7562, a control ball 7563 and a confluence block 7564. The smooth lubricating oil delivery function is achieved through precise design between the various parts. The mounting ring 7561 is fixed in the oil outlet channel 759 to play a role of stable support. One end of the return spring 7562 is firmly clamped on the mounting ring 7561, and the other end is connected to the control ball 7563 to enable it to have rebound ability. The control ball 7563 accurately adjusts the flow of oil through the action of the spring to ensure the stability of lubrication. The confluence block 7564 is installed inside the oil filling sleeve 757. As the core part of the oil circuit, it is responsible for evenly distributing the lubricating oil to the parts that need lubrication, thereby ensuring the efficient operation of the entire system.

[0062] The confluence block 7564 is arranged radially, and the outer ends of the four confluence blocks 7564 are connected to each other, and the diameter of the formed cavity is the same as the inner diameter of the oil injection sleeve 757. The radial confluence block 7564 design allows the lubricating oil to be evenly distributed from the center to the surroundings, ensuring that the lubricating oil flows smoothly and evenly throughout the system. This uniform distribution is very important for ensuring the consistency of the lubrication effect, and can avoid wear or overheating caused by insufficient lubrication in certain areas.

[0063] The outer ends of the four confluence blocks 7564 are connected to each other, and the diameter of the cavity formed is the same as the inner diameter of the oil injection sleeve 757. This design fully utilizes the space inside the oil injection sleeve 757 and avoids unnecessary gaps and dead corners. This optimized space utilization not only improves the flow efficiency of the lubricating oil, but also reduces the possibility of oil being retained in certain areas, ensuring the efficient operation of the lubrication system.

[0064] The inner diameter of the conduit block 7564 and the oil injection sleeve 757 fit perfectly to form a tight sealing structure. In this way, when the system is running, it can effectively prevent the leakage of lubricating oil or external pollutants from entering the system, maintaining the purity of the lubricating oil and the operating stability of the system.

[0065] like Fig. 9As shown, the shock absorbing assembly 76 is composed of a shock absorbing block 761, a limit slider 762, a shock absorbing spring 763 and a sliding block 764. The various components work together to effectively absorb and alleviate the vibration generated during the operation of the rotating mechanism 75, thereby improving the stability and durability of the equipment. First, the shock absorbing block 761 is firmly installed inside the rotating mechanism 75, playing a core role in support and buffering. The limit slider 762 is tightly arranged on both sides of the shock absorbing block 761 to provide additional lateral support for the shock absorbing block 761 to prevent it from deflecting or shaking during operation. The shock absorbing spring 763 is installed on the inner side of the shock absorbing block 761, and absorbs the vibration energy of the equipment during operation through its elasticity, thereby reducing the impact of vibration on the system. The sliding block 764 is connected to the other end of the shock absorbing spring 763, which plays a role in transmitting and adjusting force. The sliding block 764 can only slide in the specially provided sliding hole 754. This design limits the movement direction of the sliding block 764 and ensures that it can only move along a specific trajectory, thereby further stabilizing the working effect of the shock absorbing component 76 and ensuring that the equipment can remain stable when operating under high load.

[0066] The cross section of the shock absorbing block 761 is set to be a fan ring, and the outer side thereof is coated with a wear-resistant material. The fan ring cross section design enables the shock absorbing block 761 to form a larger contact area in the rotating mechanism 75. This design can provide a more uniform buffering and vibration absorption effect, so that the vibration and impact force can be better dispersed and alleviated, thereby improving the overall stability.

[0067] The outer surface of the shock absorbing block 761 is coated with a wear-resistant material, which can effectively resist wear and corrosion. This wear-resistant layer can significantly extend the service life of the shock absorbing block 761 and reduce the need for frequent replacement and maintenance. The coating of the wear-resistant material ensures that the shock absorbing block 761 can maintain its performance and shape stability during long-term high-intensity operation.

[0068] The design of the fan ring cross section helps to better cooperate with other components and provide more stable support. This shape allows the shock absorbing block 761 to be more firmly fixed in its position during operation, reducing component displacement or instability caused by vibration.

[0069] The fan-shaped design may also help evenly distribute the lubricant and effectively dissipate the heat. Under high load conditions, this shape can help dissipate the heat better and avoid material fatigue or performance degradation due to overheating.

[0070] In the working process of the present invention, the driving wheel 3 and the driven wheel 5 drive the flexible saw belt 6 to realize the cutting work, and the guide block mechanism 7 is responsible for pulling and limiting the position of the flexible saw belt 6, so as to ensure that the flexible saw belt 6 will not deviate, thereby ensuring the working quality;

[0071] When the flexible saw belt 6 passes through the adjustment assembly 74, its position deviation will cause the adjustment roller 743 to rotate and limit it in another direction, which can flexibly adjust the position and tension of the saw belt to ensure that the saw belt maintains the best state during high-speed operation. Through the rotation adjustment of the rotating pin 741, the rotating plate 742 can rotate flexibly within a certain range, thereby driving the adjustment roller 743 to apply appropriate force to the saw belt, so that the saw belt is always in the best working state and avoids deviation or relaxation;

[0072] When the machine is idling, the flexible saw belt 6 is in the middle of the shock absorbing component 76. When cutting, the flexible saw belt 6 will lean toward the shock absorbing component 76 on one side, pushing the shock absorbing block 761 to disperse the torque and absorb shock, ensuring the rigid force of the flexible saw belt 6 is dispersed and processed to avoid damage to the flexible saw belt 6. Long-term and multiple one-way extrusions will cause the sliding block 764 to continuously expand and contract inward in the sliding hole 754, changing the air pressure change inside the oiling sleeve 757. Since the sealing film 758 is set in one direction, the gas will squeeze the control ball 7563 through the confluence block 7564, causing it to overcome the elastic force of the reset spring 7562 and shrink. Since lubricating oil is placed in the transition sleeve 755, the lubricating oil will be ejected into the oil channel 759 under the drive of the high-pressure gas, and will be thrown outward under the centrifugal force of the rotating disk 751, thereby lubricating the guide block mechanism 7 and the flexible saw belt 6.

[0073] The staff can add lubricating oil to the oil filling sleeve 757 through the sealing film 758. The sealing film 758 is set inward and can be opened from the outside to the inside, but when the internal lubricating oil is sprayed outward, its resistance is relatively large, so there will be no oil leakage. The specific principle is that the sealing film 758 is set to be made of semi-elastic material, and the inner side is set to be hard material, which has a better effect of resisting pressure, but it can be easily opened when the staff holds the oil filling pot and inserts it.
