Description

Technical Field

[0001] This invention belongs to the field of wood processing technology, and specifically discloses a high-efficiency turning and milling device for wooden round bars. Background Technology

[0002] In the manufacturing process of wooden furniture and decorative components, it is often necessary to perform intermittent or periodic milling and turning on the surface of cylindrical wooden rods to create a distinctive and textured outline, such as European-style bedposts, stair railings, or table legs. This type of machining is usually completed using a gantry milling and turning machine or a woodworking lathe with a movable cutter head.

[0003] Currently, milling and turning operations typically integrate the turning function into the cutter head or the same spindle unit. When continuously milling and turning wooden bars of the same outer diameter, the turning process mainly produces continuous, elongated wood chips. Driven by the high-speed rotation of the cutter head, these chips tend to concentrate and splash along the tangential direction of the cutter head towards a fixed side, easily becoming entangled and accumulating. Existing devices generally suffer from the following problem: concentrated splashing towards either the direction of the cutter head's rotation or the opposite direction. When machining round wooden bars with concave or convex shapes, this type of splashed wood chips has two main negative impacts: First, in machining devices equipped with gantry cranes and linear guides, the high-speed splashed wood chips easily accumulate and adhere to the surfaces of precision moving parts such as guide rail pairs, lead screws, or sliders. Once the wood chips intrude into the track clearance, it significantly increases the moving resistance, causing the gantry crane to jam or vibrate, affecting the dimensional accuracy of continuous milling and turning. In severe cases, it can even cause track scratches or transmission component failure.

[0004] Secondly, even in simple processing equipment without tracks, large amounts of continuous or intermittent wood chips will accumulate on one side of the processing station, forming localized high piles. Especially in milling and turning, when long strips of wood chips are processed continuously, they will wrap around the station and the cutting head. This not only obstructs the operator's view and interferes with real-time observation of the processed surface quality, but also requires a long downtime for cleaning after processing because the wood chips cannot be automatically dispersed or guided for collection. Furthermore, the phenomenon of wood chips wrapping around the cutting head or clamping mechanism is frequent, which greatly reduces production efficiency and the degree of automation of the equipment.

[0005] Therefore, how to effectively guide and control the direction of wood chips while ensuring efficient and continuous milling of wooden rods to form concave and convex shapes, avoiding interference with the moving track or processing station, ensuring the use of the milling head, and achieving immediate centralized collection of wood chips are technical problems that urgently need to be solved in the current wood processing machinery field. Summary of the Invention

[0006] The purpose of this invention is to solve the problems existing in the background art, and to propose a high-efficiency turning and milling processing device for wooden round bars, including a gantry frame, a translation mechanism, an X-axis drive mechanism, a rotary pressing mechanism, a Z-axis drive mechanism, a fine-tuning mechanism, and a ball screw drive mechanism. The translation mechanism is located inside the gantry frame, and a slide is connected to one side of the gantry frame through the translation mechanism. The Z-axis drive mechanism is located on one side of the slide, and a slide table is connected to the telescopic end of the Z-axis drive mechanism. The fine-tuning mechanism is located above the slide table, and a turning and milling processing component is provided at one end of the fine-tuning mechanism. The milling and turning assembly includes a turning unit and a tool holder. The turning unit is mounted on the tool holder, which is connected to the drive end of a fine-tuning mechanism. The turning unit is used to turn wooden round bars. The slide table drives the milling and turning assembly to move back and forth on the slide table via the fine-tuning mechanism. A worktable is provided on one side of the gantry frame. A frame is fixedly installed above the worktable and near the middle. The frame is connected to a slide block via a ball screw drive mechanism at one end. Both ends of one side of the slide block extend upwards into a sleeve. Sliding members are provided at the upper part of the two sleeves. Lifting members are provided at the lower end of the sliding members. A trapezoidal hopper is provided above the sliding members. A rectangular opening adapted for the milling and turning assembly is opened inside the rear end of the trapezoidal hopper. Guide members are provided on both inner walls of the trapezoidal hopper. A V-shaped compartment is provided in the middle of the bottom of the trapezoidal hopper. Chip cutting mechanisms are provided on both sides inside the V-shaped compartment.

[0007] Throughout its operation, this device provides a continuous and automated process for wood chips, from generation, interception, guidance, cutting to discharge. It requires minimal manual intervention for cleaning, significantly improving the continuous operating time and production efficiency of the milling and turning components. At the same time, it protects precision moving parts such as the gantry and translation mechanism from wood chip intrusion, ensuring long-term machining accuracy.

[0008] In the above solution, the sliding member further includes a sliding rod, which slides vertically inside the corresponding sleeve, and a protective component is provided above the inside of the sliding rod.

[0009] In the above scheme, the lifting component further includes two sets of first hydraulic cylinders, the telescopic ends of the two first hydraulic cylinders are connected to a support base, one side of the support base is connected to the outside of two sliding rods, and the bottom of the trapezoidal hopper is fixedly connected to the upper surface of the support base.

[0010] In the above scheme, the guide component further includes multiple sets of guide sloping pieces, which are arranged at equal intervals from bottom to top along the inner wall of the trapezoidal hopper, and the size of the multiple sets of guide sloping pieces increases from bottom to top.

[0011] In the above scheme, the chip-cutting mechanism further includes a mounting base, the bottom of which is fixedly installed at the bottom of the trapezoidal bin and located inside the V-shaped bin. A bidirectional pneumatic telescopic rod is fixedly installed inside the mounting base. Both ends of the bidirectional pneumatic telescopic rod are connected to a blade bar. Mounting components are arranged at equal intervals along the horizontal direction outside the blade bar. Wide slices are fixedly installed inside each mounting component. The V-shaped bin has a cutting opening adapted to the sliding of the wide slices.

[0012] In the above scheme, the mounting component further includes a mounting base, the wide slice is fixedly installed inside the mounting base, the mounting base is connected to the blade rod by a fixing bolt with an internal thread at one end, and slope plates are fixedly installed on both sides of the lower part of the inner wall of the trapezoidal hopper. Blade holders are fixedly installed inside the two slope plates at positions corresponding to the wide slice, and blade grooves adapted to the wide slice are opened inside the blade holders.

[0013] In the above scheme, the protective component further includes a second hydraulic cylinder, which is fixedly installed above one side of the slide rod via a connecting block on the outer side. The telescopic end of the second hydraulic cylinder slides through the interior of the slide rod, and one end is connected to an arc-shaped block. Universal ball bearings are symmetrically embedded on the outer surface of the arc-shaped block.

[0014] In the above scheme, two X-axis drive mechanisms and two rotary pressing mechanisms are provided. The upper ends of both ends of the worktable are connected to the rotary pressing mechanisms through the X-axis drive mechanisms. The two rotary pressing mechanisms are symmetrically arranged and used to press against the processed wooden round rods. Suction pipes are connected and installed on both sides of the rear end of the trapezoidal bin near the bottom. The other end of the suction pipe is connected and installed with a suction device. A connecting pipe is connected and installed diagonally below one side inside the suction device. The trapezoidal bin has notches for processing wooden round rods of the same diameter on both sides. Protective rollers are installed on the outside of the trapezoidal bin near the rear end of the corresponding notch.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention features a liftable trapezoidal hopper around the processing station, with a rectangular opening at the rear end of the hopper adapted to the milling and turning assembly. This design ensures that when the cutting head of the turning unit intermittently mills the wooden rod to create concave and convex shapes, most of the flying wood chips are confined within the hopper, preventing them from directly flying onto the gantry rails or into the surrounding environment. Simultaneously, multiple layers of guide wedges with increasing dimensions from bottom to top are installed on the inner walls of both sides of the hopper. These wedges intercept wood chips at different throwing heights and guide them to the bottom of the hopper, effectively solving the problem of wood chips accumulating on one side of the processing station and eliminating the need for frequent machine shutdowns for cleaning.

[0016] 2. This invention features a V-shaped compartment at the bottom center of a trapezoidal hopper, with chip-cutting mechanisms arranged on both sides inside the V-shaped compartment. When long or tangled wood chips fall into the V-shaped compartment, a bidirectional pneumatic telescopic rod drives the blades and wide slices on both sides to reciprocate, working in conjunction with the blade holder on the ramp to create a shearing action. This actively cuts long chips into short segments, preventing them from bridging or tangling at the bottom of the hopper. This ensures that the wood chips can smoothly slide to the bottom of the V-shaped compartment, providing favorable conditions for subsequent suction or centralized discharge.

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0021] like Figures 1-7 The device for high-efficiency turning and milling of wooden round bars shown includes a gantry frame 1, a translation mechanism 2, an X-axis drive mechanism 4, a rotary pressing mechanism 5, a Z-axis drive mechanism 6, a fine-tuning mechanism 8, and a ball screw drive mechanism 14. The translation mechanism 2 is located inside the gantry frame 1. A slide is connected to one side of the gantry frame 1 through the translation mechanism 2. The Z-axis drive mechanism 6 is located on one side of the slide. A slide table 7 is connected to the telescopic end of the Z-axis drive mechanism 6. The fine-tuning mechanism 8 is located above the slide table 7. A turning and milling assembly 9 is provided at one end of the fine-tuning mechanism 8. The milling and turning assembly 9 includes a turning unit and a tool holder. The turning unit is mounted on the tool holder, which is connected to the drive end of the fine-tuning mechanism 8. The turning unit is used to turn wooden round bars. The slide table 7 drives the milling and turning assembly 9 to move back and forth on the slide table 7 through the fine-tuning mechanism 8. A worktable 3 is provided on one side of the gantry frame 1. A frame 12 is fixedly installed above the worktable 3 and near the middle. The frame 12 is connected to a slide 11 through a ball screw drive mechanism 14 at one end. Both ends of the slide 11 extend upwards to form a sleeve 16. Sliding parts are provided on the upper part of the two sleeves 16. Lifting parts are provided at the lower end of the sliding parts. A trapezoidal bin 10 is provided above the sliding parts. A rectangular opening adapted to the milling and turning assembly 9 is opened inside the rear end of the trapezoidal bin 10. Guide parts are provided on both inner walls of the trapezoidal bin 10. A V-shaped bin 21 is provided in the middle of the bottom of the trapezoidal bin 10. Chip cutting mechanisms are provided on both sides inside the V-shaped bin 21.

[0022] In this embodiment, the translation mechanism 2 is a combination structure of a linear guide pair and a ball screw driven by a servo motor, which is commonly used in the art, and is used to drive the carriage to move back and forth along the X-axis direction; the Z-axis drive mechanism 6 can be a servo electric cylinder or a hydraulic cylinder, which is used to control the feed and retraction of the milling and turning assembly 9; the fine adjustment mechanism 8 is used to drive the milling and turning assembly 9 to move back and forth on the slide table 7 to achieve detailed adjustment of the milling depth, and at the same time, it also realizes the feed and retraction actions of the milling and turning assembly 9; the rectangular opening is used for the cutter head to enter the trapezoidal hopper 10 to mill the wooden round bar; the V-shaped hopper 21 is used to collect the falling wood chips.

[0023] It is important to note that, to ensure the milling cutter head of the turning assembly 9 always passes through the rectangular opening at the rear end of the trapezoidal hopper 10 for machining, the translation mechanism 2 and the ball screw drive mechanism 14 must be precisely synchronized. The control system uses a CNC controller or PLC to ensure that the servo motors of the same specifications are driven. The control system sends identical commands to the two servo drives in the translation mechanism 2 and the ball screw drive mechanism 14, and reads the encoder feedback of the two motors in real time for closed-loop comparison. When the detected position deviation exceeds the set threshold, the controller will immediately fine-tune the speed of either motor to ensure that the carriage and the slide block 11 move synchronously along the X-axis of the wooden bar with identical speed, acceleration, and position. This control drive is common in the existing field and will not be described in detail. Specifically, the turning unit includes at least a turning tool detachably mounted on the tool holder 29, used for turning the outer diameter of a rotating wooden bar to form a basic rotating surface with concave and convex contours. When the milling and turning unit performs concave and convex contour machining on the wooden bar, the tool tip of the turning unit is maintained at a preset relative position at one end of the wooden bar. The CNC controller controls the translation mechanism 2 and the Z-axis drive mechanism 6 in real time according to the preset concave and convex contour curve. When it is necessary to machine an arc-shaped protrusion, the turning tool moves axially while the radial feed changes according to the curve of the protrusion, thereby turning out a continuously changing outer diameter. Through multi-axis linkage, various concave and convex, complex and varied shapes can be efficiently machined on the surface of the wooden bar.

[0024] The sliding component includes a slide rod 25, which slides vertically inside the corresponding sleeve 16, and a protective component is provided on the upper part of the slide rod 25.

[0025] In this embodiment, the vertical sliding of the slide bar 25 can adjust the height of the protective component supported above.

[0026] The lifting component includes two sets of first hydraulic cylinders 13. The extension and retraction ends of the two first hydraulic cylinders 13 are connected to a support base 20. One side of the support base 20 is connected to the outside of two sliding rods 25. The bottom of the trapezoidal hopper 10 is fixedly connected to the upper surface of the support base 20.

[0027] In this embodiment, the two sets of first hydraulic cylinders 13 simultaneously lift the support base 20, which can precisely adjust the overall height of the trapezoidal hopper 10, and at the same time reduce the space occupied before and after processing.

[0028] The guide includes multiple sets of guide blades 17, which are arranged at equal intervals from bottom to top along the inner wall of the trapezoidal hopper 10, and the size of the multiple sets of guide blades 17 increases from bottom to top.

[0029] In this embodiment, the width and length of the multiple sets of guide blades 17 increase sequentially from bottom to top. This stepped layout is designed to intercept wood chips at different throwing heights in a tiered manner. Wood chips thrown from lower positions at higher speeds are first intercepted and redirected by the larger upper guide blades 17, while wood chips splashing from higher positions are captured by the corresponding lower guide blades 17. All intercepted wood chips eventually slide down the inclined blade surfaces to the bottom of the trapezoidal hopper 10.

[0030] The chip-cutting mechanism includes a mounting base 26. The bottom of the mounting base 26 is fixedly installed at the bottom of the trapezoidal bin 10 and located inside the V-shaped bin 21. A bidirectional pneumatic telescopic rod 27 is fixedly installed inside the mounting base 26. Both ends of the bidirectional pneumatic telescopic rod 27 are connected to a blade bar 32. Mounting components are arranged at equal intervals along the horizontal direction on the outside of the blade bar 32. Wide slices 33 are fixedly installed inside the mounting components. The V-shaped bin 21 has a cutting opening that is adapted to the sliding of the wide slices 33.

[0031] In this embodiment, when long or tangled wood chips fall into the V-shaped bin 21, the bidirectional pneumatic telescopic rod 27 drives the blades 32 and wide slices 33 on both sides to perform reciprocating shearing motions within the cut of the V-shaped bin 21, actively cutting the long wood chips and preventing them from forming bridges or tangling blockages at the bottom of the trapezoidal bin 10, thus ensuring that the wood chips can sink smoothly.

[0032] It should be noted that since the round wooden rods being processed need to be shaped into concave and convex forms, there are clear boundaries between the lengths of the wood chips. Short wood chips sink directly to the bottom of the trapezoidal hopper 10, while long chips are layered and eventually cut off by the wide slice 33. Therefore, the blade 32 will not cause blockage.

[0033] The mounting components include a mounting base 31, with a wide slice 33 fixedly installed inside the mounting base 31. The mounting base 31 is connected to the cutter bar 32 via a fixing bolt 30 with an internal thread at one end. Slope plates 28 are fixedly installed on both sides of the lower inner wall of the trapezoidal hopper 10. A cutter holder 29 is fixedly installed inside the two slope plates 28 at the position corresponding to the wide slice 33. The cutter holder 29 has a cutter groove inside that is compatible with the wide slice 33.

[0034] In this embodiment, when the bidirectional pneumatic telescopic rod 27 drives the wide slice 33 to slide towards the slope plates 28 on both sides, the blade of the wide slice 33 will precisely enter the blade groove of the blade holder 29, forming a shearing pair similar to a guillotine, thereby efficiently and neatly cutting the wood chips. The cut wood chips are smaller in volume and are more easily sucked away by negative pressure.

[0035] The protective component includes a second hydraulic cylinder 22, which is fixedly installed on one side of the slide rod 25 via a connecting block on the outer side. The telescopic end of the second hydraulic cylinder 22 slides through the interior of the slide rod 25, and one end is connected to an arc-shaped block 23. Universal ball bearings 24 are symmetrically embedded on the outer surface of the arc-shaped block 23.

[0036] In this embodiment, before the milling and turning process begins, the second hydraulic cylinder 22 drives the arc-shaped block 23 to gently roll against the non-machined area of ​​the wooden rod. When the milling and turning assembly 9 performs intermittent cutting and generates radial impact force, the arc-shaped block 23 provides reverse support to prevent the wooden rod from shifting or vibrating violently. The universal ball bearings 24 directly contact the surface of the wooden rod and roll with the rotation of the wooden rod, minimizing frictional damage to the surface of the wooden rod and effectively providing alignment and protection.

[0037] Both the X-axis drive mechanism 4 and the rotary pressing mechanism 5 are provided in twos. The upper ends of both ends of the worktable 3 are connected to the rotary pressing mechanism 5 through the X-axis drive mechanism 4. The two rotary pressing mechanisms 5 are symmetrically arranged and used to press the processed wooden round rods. Suction pipes are connected to both sides of the rear end of the trapezoidal bin 10 and near the bottom. The other end of the suction pipe is connected to the suction device 18. A connecting pipe 19 is connected to one side of the suction device 18 at an angle below. The trapezoidal bin 10 has notches for processing wooden round rods of the same diameter on both sides. Protective rollers 15 are installed on the outside of the trapezoidal bin 10 and near the rear end of the corresponding notch.

[0038] In this embodiment, two rotating pressing mechanisms 5 are symmetrically arranged to firmly press against the wooden round bar from both ends and drive it to rotate, thus ensuring the stability of long bar processing.

[0039] A connecting pipe 19 is installed diagonally downwards on one side of the suction device 18 to discharge the collected wood chips into an external dust collection bag or container. This design enables immediate and centralized cleaning of wood chips.

[0040] Both sides of the trapezoidal bin 10 have notches for processing wooden round bars of the same diameter, allowing the wooden round bars to pass through. Protective rollers 15 are installed on the exterior of the trapezoidal bin 10, near the rear end of the corresponding notch. The protective rollers 15 not only provide rolling guidance when the wooden round bars enter and exit, but also help limit the radial runout of the wooden round bars during processing, forming a multi-point support together with the arc-shaped block 23.

[0041] In summary, the translation mechanism 2, X-axis drive mechanism 4, Z-axis drive mechanism 6, fine-tuning mechanism 8, and ball screw drive mechanism 14 in this device preferably employ a structure of servo motors combined with ball screws and high-precision linear guide pairs to achieve precise displacement and synchronous control. The specific selection can be customized according to the processing load and accuracy requirements.

[0042] Working Principle: Upon commissioning, the equipment is first adjusted according to the diameter and length of the wooden rod to be processed. The X-axis drive mechanisms 4 at both ends of the worktable 3 drive two rotating pressing mechanisms 5 to move relative to each other and open a certain distance. The operator inserts the wooden rod from the side, allowing it to pass through the notches on both sides of the trapezoidal hopper 10. At this point, the wooden rod is entirely inside the trapezoidal hopper 10, with both ends protruding outside. Subsequently, the two rotating pressing mechanisms 5 move towards each other, pressing and fixing the wooden rod from both ends, and driving the wooden rod to rotate around its own axis. At this time, the trapezoidal hopper 10 covers the wooden rod through the notches on both sides, allowing the wooden rod to rotate freely within the notches without interfering with the trapezoidal hopper 10.

[0043] Before machining begins, a synchronous motion relationship needs to be established between the milling and turning assembly 9 and the trapezoidal hopper 10. The translation mechanism 2 inside the gantry 1 drives the carriage to move laterally, causing the Z-axis drive mechanism 6, the slide table 7, and the milling and turning assembly 9 to move along the X-axis. Simultaneously, the ball screw drive mechanism 14 inside the frame 12 drives the slide 11 to move synchronously along the length of the worktable 3 at the same speed and direction. The slide 11, through the sleeve 16, sliding components, and lifting components, drives the trapezoidal hopper 10 to follow suit. The purpose of this synchronous motion is to ensure that the rectangular opening inside the rear end of the trapezoidal hopper 10 is always aligned with the machining head of the milling and turning assembly 9, ensuring that the cutting head can pass through the rectangular opening into the trapezoidal hopper 10 to machine the wooden rod. Furthermore, regardless of the position of the milling and turning assembly 9 during axial feed, the rectangular opening of the trapezoidal hopper 10 always remains directly opposite the cutting head. Before the milling and turning process begins, the protective components intervene first. The second hydraulic cylinder 22, located above the slide bar 25, is activated, extending its telescopic end forward and sliding through the slide bar 25. This pushes the arc-shaped block 23 towards the non-machined area of ​​the wooden rod (i.e., the reserved cylindrical surface that has not been milled), until the universal ball bearings 24 embedded on the outer surface of the arc-shaped block 23 slightly press against and adhere to the surface of the wooden rod. The purpose of this action is that when the subsequent milling assembly 9 intermittently cuts one side of the wooden rod, the radial cutting force generated by the tool cutting into the wooden rod will cause the wooden rod to have a slight tendency to detach from the rotating pressing mechanism 5 or vibrate. At this time, the arc-shaped block 23 and the universal ball bearings 24 on it provide auxiliary support and straightening from the other side, preventing the wooden rod from shifting or jumping during the milling process. At the same time, the universal ball bearings 24 roll with the rotation of the wooden rod, avoiding friction and scratches. The Z-axis drive mechanism 6 drives the slide table 7 to extend forward, allowing the cutting head of the milling assembly 9 to enter the trapezoidal hopper 10 through the rectangular opening and contact the surface of the wooden rod. The fine-tuning mechanism 8 on the slide table 7 drives the milling and turning assembly 9 to make fine adjustments back and forth on the slide table 7 to control the milling depth. During the machining process, the milling and turning assembly 9 intermittently cuts the surface of the wooden bar to form concave and convex shapes. At the same time, the translation mechanism 2 and the ball screw drive mechanism 14 move synchronously, so that the cutter head continuously feeds along the axial direction of the wooden bar. The notch of the trapezoidal bin 10 always follows the movement of the cutter head, ensuring that the point of wood chip generation is always within the effective coverage area inside the trapezoidal bin 10. During the milling process, a large amount of wood chips generated by the high-speed rotating cutter head are effectively blocked by the four side walls of the trapezoidal bin 10, greatly reducing the amount of wood chips splashing onto the track of the gantry 1 or the surrounding environment. The splashed wood chips collide with multiple sets of guide wedges 17 arranged on the inner walls on both sides inside the trapezoidal bin 10. The guide wedges 17 increase in size from bottom to top, which can intercept wood chips at different projection heights step by step and guide them downward. The wood chips eventually collect in the V-shaped bin 21 at the bottom of the trapezoidal bin 10. To prevent long or tangled wood chips from bridging and clogging in the V-shaped bin 21, the chip-cutting mechanism is automatically activated.The bidirectional pneumatic telescopic rod 27 inside the mounting base 26 reciprocates periodically or continuously, driving the blade rods 32 at both ends to move reciprocally in the horizontal direction. The blade rods 32 drive multiple card holders 31 and their internal wide slices 33 to slide back and forth in the cut of the V-shaped chamber 21. When the wide slices 33 slide to both sides, their blades form a shearing engagement with the blade grooves inside the blade holder 29 fixedly installed on the slope plate 28, cutting the long wood chips falling into the V-shaped chamber 21 into short segments. The cut short wood chips naturally sink to the bottom of the V-shaped chamber 21. At the same time, the suction device 18, connected to the suction pipes on both sides below the rear end of the trapezoidal hopper 10, continues to work, generating negative pressure, sucking the short wood chips accumulated at the bottom of the V-shaped chamber 21 into the suction device 18 through the suction pipes, and then discharging them into an external collection container through the connecting pipe 19. Thus, the wood chip processing from generation, interception, guidance, cutting to discharge is a continuous and automated process.

[0044] Once a wooden bar is finished, the Z-axis drive mechanism 6 retracts the milling and turning assembly 9, the second hydraulic cylinder 22 retracts the arc block 23, and the rotating pressing mechanism 5 disengages from both ends of the wooden bar, allowing the finished wooden bar to be removed from the notched side for processing the next wooden bar.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
