Description

Technical Field

[0001] This invention relates to the field of anti-eccentric load technology for roller presses, specifically a multi-condition composite anti-eccentric load roller press. Background Technology

[0002] Roller presses are core equipment for fine crushing and pre-grinding of materials in the cement, mining, metallurgy, and building materials industries. With their advantages of high efficiency, energy saving, and low loss, they are widely used in the crushing and processing of hard materials such as ores, clinker, and steel slag. In actual industrial production conditions, roller presses operate under heavy loads, impacts, and continuous operation for extended periods. Affected by multiple factors such as uneven material distribution, equipment installation deviations, frame deformation under stress, uneven roller wear, and hydraulic system pressure imbalances, the equipment is highly susceptible to off-center load failures.

[0003] Uneven loading directly leads to deviations in the parallelism of the moving and stationary rollers, resulting in uneven stress on the bearing housings on both sides of the equipment and causing unilateral overload or unilateral unload conditions. This also triggers a series of problems such as accelerated localized wear on the roller surface, premature damage to bearings and seals, excessive equipment vibration, and roller gap misalignment. These issues not only significantly increase equipment failure rates and maintenance costs but also cause uneven material particle size distribution, reduced production capacity, and severely restrict the continuous and stable operation of the production line. A typical roller press includes a drive module with multiple sets of rollers symmetrically mounted on its output end. Gaps are left between these rollers. Raw materials are fed into these gaps, and the opposing rotation of the rollers generates pressure, thus crushing the material. Existing roller presses address the issue of uneven loading through several measures: a front-end feeding guide and equalization structure for source control; a central mechanical synchronization and limiting structure to ensure the parallelism of the two rollers; and a rear-end hydraulic dynamic load-equalizing structure for dynamic compensation.

[0004] Common front-end feeding and distribution structures often employ spiral feeders for quantitative and constant-pressure feeding, effectively reducing uneven loading caused by inconsistent feeding amounts. However, to avoid interference with the rotating pressure rollers below, the bottom of the distribution plate at the end of the front-end feeding and distribution structure must maintain a safe distance from the roller gap. Within this drop range, the landing point of the heavy object is almost uncontrollable due to gravity and inertia. Since the opening of the distribution plate is fixed, the material will inevitably hit the same area of ​​the roller surface, leading to uneven wear on the roller surface over time. Furthermore, because the roller gap has a certain length, existing distribution plates can ensure that the raw material falls into a set area within the roller gap during feeding, but they cannot precisely control its specific landing point. This can easily lead to uneven loading by the raw material only falling into a certain range of the set area during feeding. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-condition composite anti-eccentric load roller press to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A multi-condition composite anti-eccentric load roller press includes a frame, on which a roller pressing module is installed. The roller pressing module includes two sets of pressure rollers that can rotate synchronously and in opposite directions. A balancing module is provided on the frame. The balancing module is used to dynamically adjust the parallelism of the two sets of pressure rollers. It also includes a hopper installed on the frame, the hopper having a feeding module installed at its inlet end and a material distribution component at its outlet end. The material distribution component includes multiple sets of telescopic plates, which cooperate with the hopper to form an outlet channel for the raw material to pass through. The outlet channel is located between multiple sets of pressure rollers. The frame is equipped with a uniform distribution component, which can drive the telescopic plate to reciprocate along the axial direction of the pressure roller, so that the discharge channel reciprocates between multiple sets of pressure rollers, thereby performing a uniform feeding action of raw materials. The frame is equipped with a shaking component and an adjusting component. The shaking component is used to drive the telescopic plate to shake; the adjusting component is used to adjust the initial effective conduction area of ​​the discharge channel.

[0007] The multi-condition composite anti-eccentric load roller press described above: the material distribution component includes rotating plates rotatably installed at both ends of the hopper, the rotating plates being slidably connected to the telescopic plates; a floating frame is provided on the frame, and a sliding groove is provided on the floating frame; a fixed column is installed on the telescopic plate and slidably engaged with the sliding groove; and the fixed column is rotatably connected to the adjusting component.

[0008] As described above, the multi-condition composite anti-eccentric load roller press has the following features: the rotating plate and the end near the telescopic plate are provided with a ramp, which is used to guide the raw material to converge at the discharge channel and prevent the raw material from accumulating or bridging at the connection between the rotating plate and the telescopic plate; the surfaces of the rotating plate and the telescopic plate are both covered with wear-resistant ceramic liners.

[0009] As described above, the multi-condition composite anti-eccentric load roller press includes a guide column mounted on the frame, a movable frame slidably mounted on the guide column, the movable frame being connected to the floating frame via a floating component, a rotating shaft rotatably mounted on the frame, one end of the rotating shaft being mounted on the output end of the drive module, a groove group being formed on the rotating shaft, and a protruding column slidably fitted into the groove group being mounted on the movable frame.

[0010] The multi-condition composite anti-eccentric load roller press described above: the trough assembly includes a first-end flat trough, a moving inclined trough, an end flat trough, and a reset inclined trough; wherein the two ends of the first-end flat trough are respectively connected to one end of the moving inclined trough and the reset inclined trough, and the two ends of the end flat trough are respectively connected to the other end of the moving inclined trough and the reset inclined trough; when the protruding column cooperates with the moving inclined trough or the reset inclined trough, the moving frame can move horizontally from one end of the hopper to the other end along the axial direction of the rotating shaft; when the first-end flat trough and the end flat trough cooperate with the protruding column, the moving frame remains in a fixed position to reduce the influence of inertia on the structure.

[0011] The multi-condition composite anti-eccentric load roller press described above: the floating component includes multiple sets of sliding columns installed on the floating frame, the sliding columns are slidably connected to the moving frame, and springs are sleeved on the sliding columns, with the two ends of the springs abutting against the moving frame and the floating frame respectively.

[0012] As described above, the multi-condition composite anti-eccentric load roller press has the following characteristics: the spring force is greater than the resistance of the moving frame to drive the floating frame to move, that is, when the moving frame moves, the floating frame can move synchronously through the drive of the spring.

[0013] The multi-condition composite anti-eccentric load roller press described above: the vibration component includes a vibration motor mounted on the moving frame, a rotating disk mounted on the output end of the vibration motor, a plurality of active tooth blocks equidistantly arranged along its circumference mounted on the rotating disk, a fixed disk mounted on the floating frame, a plurality of driven tooth blocks equidistantly arranged along its circumference mounted on the fixed disk; the active tooth blocks and the driven tooth blocks are meshable; both the fixed disk and the rotating disk are made of alloy material; and the contact surfaces of both are coated with a lubricating coating.

[0014] The multi-condition composite anti-eccentric load roller press described above: the adjusting component includes an adjusting motor mounted on a floating frame, a bidirectional lead screw mounted on the output end of the adjusting motor, and threaded sleeves that are threadedly engaged with the bidirectional lead screw are slidably mounted on both ends of the floating frame, and the threaded sleeves are rotatably connected to the fixed column.

[0015] As described above, the multi-condition composite anti-eccentric load roller press: during the reciprocating movement of the moving frame along the axis of the pressure roller caused by the action of the uniform distribution component, the telescopic plate can drive the rotating plate to rotate, and one set of the telescopic plates slides inward on the rotating plate, while the other set of telescopic plates slides outward inside the rotating plate, so that the discharge channel reciprocates along the axis of the pressure roller, thereby uniformly feeding the raw material between multiple sets of pressure rollers; at the same time, the floating frame is driven to reciprocate within the moving frame by the shaking component, so that the discharge channel performs a small-amplitude axial reciprocating movement during the reciprocating movement.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By driving the moving frame to move through the uniformly distributed component and driving the telescopic plate and rotating plate to rotate through the floating frame, the discharge channel moves back and forth along the roller gap, thereby feeding the raw material back and forth sequentially along the axis of the pressure roller. Since the discharge channel moves in real time throughout the feeding process, no position allows the material to remain for a long time, which can avoid local wear of the roller surface and bearing overload caused by concentrated material accumulation on one side; that is, since the raw material is relatively uniformly distributed along the roller gap, during the process of the pressure roller rotating to roll the raw material, the raw material between the roller gaps passes through the roller gaps relatively synchronously. Therefore, during the entire continuous operation, the force on the roller surface always remains relatively balanced, effectively preventing equipment failure and uneven load problems caused by excessive local pressure. 2. The vibrating component drives the floating frame to move independently with high frequency and small amplitude relative to the moving frame during the reciprocating movement of the moving frame. This superposition of large stroke slow uniform distribution and small stroke fast vibration ensures that the raw material is both flattened and loosened during the falling process, effectively avoiding local accumulation caused by poor fluidity.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0031] Please see Figures 1-11 As an embodiment of the present invention, the multi-condition composite anti-eccentric load roller press includes a frame 1, on which a roller pressing module is installed. The roller pressing module includes two sets of pressure rollers 4 that can rotate synchronously and in opposite directions. A balancing module 5 is provided on the frame 1. The balancing module 5 is used to dynamically adjust the parallelism of the two sets of pressure rollers 4. It also includes a hopper 3 installed on the frame 1. The feeding end of the hopper 3 is equipped with a feeding module 2, and its discharge end is provided with a material distribution component. The material distribution component includes multiple sets of telescopic plates 7. The multiple sets of telescopic plates 7 cooperate with the hopper 3 to form a discharge channel 301 for the passage of raw materials. The discharge channel 301 is located between multiple sets of pressure rollers 4. The frame 1 is provided with a uniform distribution component, which can drive the telescopic plate 7 to reciprocate along the axial direction of the pressure roller 4, so that the discharge channel 301 reciprocates between multiple sets of pressure rollers 4, thereby performing the uniform feeding action of raw materials. The frame 1 is equipped with a shaking component and an adjusting component. The shaking component is used to drive the telescopic plate 7 to shake. The adjusting component is used to adjust the initial effective conduction area of ​​the discharge channel 301.

[0032] In this embodiment, the feeding module 2 monitors the material pressure in real time, adjusts the rotation speed in a closed loop, maintains stable material pressure, and avoids sudden increases or decreases in material pressure, so as to achieve constant pressure quantitative feeding.

[0033] The raw materials fed by the feeding module 2 will enter the hopper 3, where they will be buffered and distributed. The raw materials will then be fed into the pressure rollers 4 through the discharge channel 301.

[0034] The balancing module 5 is used to collect the pressure of the bearing seats on both sides and the displacement of the roller gap in real time. When a load deviation is detected, it automatically adjusts the pressure on both sides to adjust the parallelism of the two sets of pressure rollers 4, realizes dynamic compensation of load difference, and realizes real-time correction of off-center load, adapting to the dynamic off-center load problem caused by working condition fluctuations.

[0035] With the frame 1 full, subsequent raw materials are fed in an orderly manner. During the feeding process, the distribution component drives multiple sets of telescopic plates 7 to move back and forth along the axis of the pressure roller 4 at one end, thereby changing the corresponding position of the discharge channel 301 and the roller gap of the multiple sets of pressure rollers 4 in real time. That is, the discharge channel 301 moves back and forth along the roller gap, thereby feeding the raw materials back and forth along the axis of the pressure roller 4. Since the discharge channel 301 moves in real time throughout the feeding process, no position allows the material to remain for a long time, which can avoid local wear of the roller surface and bearing overload caused by concentrated material accumulation on one side. That is, since the raw material is relatively evenly distributed along the roller gap, during the relative rotation of the pressure roller 4 to roll the raw material, the raw material between the roller gaps passes through the roller gaps relatively synchronously. Therefore, during the entire continuous operation, the force on the roller surface always remains relatively balanced, effectively preventing equipment failure and uneven load problems caused by excessive local pressure.

[0036] As a further embodiment of the present invention, the material distribution component includes a rotating plate 6 rotatably mounted at both ends of the hopper 3, the rotating plate 6 being slidably connected to the telescopic plate 7; a floating frame 11 is provided on the frame 1, the floating frame 11 having a sliding groove 1102; a fixed column 701 is installed on the telescopic plate 7 and slidably engaged with the sliding groove 1102; and the fixed column 701 is rotatably connected to the adjusting component.

[0037] In this embodiment, under the limiting action of the adjusting member, the relative distance between the fixing columns 701 is fixed, and the vertical position of the fixing columns 701 on the hopper 3 does not change.

[0038] As the uniformly distributed component drives the floating frame 11 to reciprocate, the moving floating frame 11 can drive multiple sets of fixed columns 701 to move synchronously. During the movement, the angle between the distribution plate composed of the telescopic plate 7 and the rotating plate 6 and the end face of the floating frame 11 and the feed end of the hopper 3 rotates, that is, the telescopic plate 7 drives the rotating plate 6 to rotate. Among them, one set of telescopic plates 7 slides inward within the rotating plate 6, and the length of the distribution plate composed of the two becomes shorter; while the other set of telescopic plates 7 slides outward within the rotating plate 6, and the length of the distribution plate composed of the two becomes longer. This ensures that the discharge channel 301 always maintains a tight fit with the inner wall of the hopper 3 when it moves laterally along the roller gap. On the one hand, the adaptive oscillation of the rotating plate 6 eliminates dead angles when the telescopic plate 7 moves, preventing raw materials from accumulating in corners; on the other hand, it ensures that the effective conduction area of ​​the discharge channel 301 remains constant (preset by the adjusting component) regardless of its position, ensuring the uniform distribution accuracy of the raw materials on the roller surface.

[0039] As a further embodiment of the present invention, the rotating plate 6 and the end near the telescopic plate 7 are provided with a ramp 601. The ramp 601 is used to guide the raw material to converge at the discharge channel 301 and to prevent the raw material from accumulating or bridging at the connection between the rotating plate 6 and the telescopic plate 7. The surfaces of the rotating plate 6 and the telescopic plate 7 are both covered with wear-resistant ceramic liners.

[0040] In this embodiment, the synergistic effect of the ramp 601 and the wear-resistant ceramic liner provides a dual guarantee for preventing jamming and resisting wear of the material distribution component.

[0041] For raw materials with high viscosity or high moisture content, the ramp 601 changes the direction of force on the raw materials, using the component of gravity to overcome the internal friction between the raw materials, forcing the raw materials to converge towards the center and fall vertically, effectively preventing the formation of an arched bridge above the discharge port. In other words, by setting up the ramp 601, the raw material debris stuck to the telescopic plate 7 can be removed during the inward sliding of the rotating plate 6, thereby eliminating the impact of jamming.

[0042] As a further embodiment of the present invention, the uniform distribution component includes a guide post 8 mounted on the frame 1, a movable frame 10 slidably mounted on the guide post 8, the movable frame 10 being connected to the floating frame 11 via a floating component, a rotating shaft 9 rotatably mounted on the frame 1, one end of the rotating shaft 9 being mounted on the output end of the drive module, a slot group being formed on the rotating shaft 9, and a protruding post 1001 slidably engaging with the slot group being mounted on the movable frame 10.

[0043] As a further embodiment of the present invention, the trough assembly includes a front flat trough 901, a moving inclined trough 902, a rear flat trough 903, and a reset inclined trough 904; wherein the two ends of the front flat trough 901 are respectively connected to one end of the moving inclined trough 902 and the reset inclined trough 904, and the two ends of the rear flat trough 903 are respectively connected to the other end of the moving inclined trough 902 and the reset inclined trough 904; when the protruding column 1001 is engaged with the moving inclined trough 902 or the reset inclined trough 904, the moving frame 10 can move horizontally from one end of the hopper 3 to the other end along the axial direction of the rotating shaft 9; when the front flat trough 901 and the rear flat trough 903 are engaged with the protruding column 1001, the moving frame 10 remains in a fixed position to reduce the influence of inertia on the structure.

[0044] In this embodiment, when the drive device operates, it can drive the rotating shaft 9 to rotate, thereby causing the protruding column 1001 to slide in the groove.

[0045] In the initial position, the protruding column 1001 is located at the connection between the reset inclined groove 904 and the first end flat groove 901. When the rotating shaft 9 rotates, the protruding column 1001 first rotates in the first end flat groove 901, and at this time the position of the moving frame 10 remains unchanged.

[0046] Then the protruding column 1001 slides in the moving inclined groove 902 toward the end flat groove 903. During this process, the squeezing action of the wall of the moving inclined groove 902 on the protruding column 1001 can drive the moving frame 10 to move from one end of the hopper 3 to the other end.

[0047] Afterwards, the protruding column 1001 slides in the end flat groove 903. During this process, the position of the moving frame 10 remains unchanged. Through the static effect of this stage, the influence of inertia on the uniformly distributed structure can be effectively eliminated, thereby improving the service life of the device.

[0048] Finally, the protruding column 1001 slides in the reset inclined groove 904 toward the first end flat groove 901. Through the squeezing action of the groove wall of the reset inclined groove 904 on the protruding column 1001, the moving frame 10 can be driven to move from one end of the hopper 3 to the other end, which is the reset process.

[0049] During the feeding process, the rotating shaft 9 rotates continuously, thereby driving the moving frame 10 to move back and forth along the axial direction of the pressure roller 4 through the mutual cooperation of the protruding column 1001 and the groove group, so as to drive the floating frame 11 to move synchronously through the floating parts, thereby driving the discharge channel 301 to change its position in real time.

[0050] Since the discharge channel 301 moves in real time throughout the feeding process, no material can remain in any position for an extended period of time, thus avoiding localized wear on the roller surface and bearing overload caused by concentrated material accumulation on one side. In other words, since the raw material is relatively evenly distributed along the roller gap, the material between the roller gaps passes through the roller gaps relatively synchronously during the relative rotation of the pressure roller 4 to press the raw material. Therefore, the force on the roller surface remains relatively balanced throughout the continuous operation, effectively preventing equipment failure and uneven load problems caused by excessive local pressure.

[0051] As a further embodiment of the present invention, the floating component includes multiple sets of sliding columns 1101 mounted on the floating frame 11. The sliding columns 1101 are slidably connected to the moving frame 10. A spring 12 is sleeved on the sliding column 1101, and the two ends of the spring 12 abut against the moving frame 10 and the floating frame 11, respectively.

[0052] As a further embodiment of the present invention, the elastic force of the spring 12 is greater than the resistance of the moving frame 10 to drive the floating frame 11 to move, that is, when the moving frame 10 moves, the floating frame 11 can move synchronously through the driving force of the spring 12.

[0053] As a further embodiment of the present invention, the vibration component includes a vibration motor 16 mounted on the moving frame 10, a rotating disk 17 mounted on the output end of the vibration motor 16, a plurality of active tooth blocks 1701 equidistantly arranged along its circumference mounted on the rotating disk 17, a fixed disk 18 mounted on the floating frame 11, a plurality of driven tooth blocks 1801 equidistantly arranged along its circumference mounted on the fixed disk 18; the active tooth blocks 1701 and the driven tooth blocks 1801 are meshable; both the fixed disk 18 and the rotating disk 17 are made of alloy material; and the contact surfaces of the two are coated with a lubricating coating.

[0054] In this embodiment, during the reciprocating movement of the moving frame 10, the floating frame 11 can be driven to move synchronously by the elastic force of the spring 12 (the spring 12 has an initial compression).

[0055] During the operation of the uniformly distributed component, the vibration motor 16 is controlled to rotate, thereby driving the rotating disk 17 to rotate, which in turn drives multiple sets of active tooth blocks 1701 to rotate synchronously. When the active tooth block 1701 rotates, the pressing action between its tooth surface and the tooth surface of the driven tooth block 1801 causes the fixed disk 18 to have a component force that moves along its axial direction, thereby driving the floating frame 11 to move to one side within the moving frame 10 and compressing the spring 12. When one active tooth block 1701 separates from one driven tooth block 1801, under the elastic force of the spring 12, the fixed disk 18 will move in the opposite direction along its axial direction, thereby driving the floating frame 11 to reset and causing another driven tooth block 1801 to re-mesh with another active tooth block 1701.

[0056] Because the elastic force of spring 12 is greater than the moving resistance, the reciprocating movement of moving frame 10 can be synchronously transmitted to floating frame 11 without lag through spring 12, ensuring the certainty of the fabric trajectory; at the same time, spring 12 also acts as an elastic energy accumulator, allowing floating frame 11 to move independently with high frequency and small amplitude relative to moving frame 10 under the drive of the shaking component; this superposition of large stroke slow uniform distribution and small stroke fast shaking makes the raw material both flattened and loosened during the falling process, effectively avoiding local accumulation caused by poor fluidity.

[0057] As a further embodiment of the present invention, the adjusting component includes an adjusting motor 14 mounted on the floating frame 11, a bidirectional lead screw 15 mounted on the output end of the adjusting motor 14, and threaded sleeves 13 that are threadedly engaged with the bidirectional lead screw 15 are slidably mounted on both ends of the floating frame 11, and the threaded sleeves 13 are rotatably connected to the fixed column 701.

[0058] In this embodiment, the spacing between the fixed columns 701 is adjusted according to the required particle size of the raw material to change the preset effective area of ​​the discharge channel 301.

[0059] By controlling the operation of the regulating motor 14, the bidirectional lead screw 15 is driven to rotate, thereby driving multiple sets of threaded sleeves 13 to move closer or further apart through the threaded engagement. During this process, the fixed column 701 slides in the slide groove 1102. After the regulating motor 14 stops, the relative distance of the fixed column 701 remains unchanged through the self-locking property of the threaded engagement, thereby ensuring that the equipment is not prone to uneven material distribution due to sudden changes in the effective area of ​​the discharge channel 301 during operation.

[0060] As a further embodiment of the present invention, during the reciprocating movement of the moving frame 10 along the axis of the pressure roller 4 driven by the action of the uniform distribution member, the telescopic plate 7 can drive the rotating plate 6 to rotate, and one set of the telescopic plates 7 slides inward on the rotating plate 6, while the other set of the telescopic plates 7 slides outward within the rotating plate 6, so that the discharge channel 301 reciprocates along the axis of the pressure roller 4, thereby uniformly distributing the raw material among the multiple sets of pressure rollers 4; at the same time, the floating frame 11 is driven to reciprocate within the moving frame 10 by the shaking member, so that the discharge channel 301 performs a small-amplitude axial reciprocating movement during the reciprocating movement.

[0061] In this embodiment, when the uniform distribution component drives the moving frame 10 to reciprocate linearly along the axial direction of the pressure roller 4, since the floating frame 11 is flexibly connected to the moving frame 10 through the spring 12, and the telescopic plate 7 is restricted in the slide groove 1102 of the floating frame 11 through the fixed column 701, the movement of the moving frame 10 will be rigidly transmitted to the floating frame 11 through the elastic force of the spring 12, driving the entire material distribution component to move horizontally synchronously.

[0062] During this process, since the telescopic plate 7 and the rotating plate 6 are slidably connected, and the rotating plate 6 is rotatably installed at both ends of the hopper 3, when the floating frame 11 drives the telescopic plate 7 to make lateral displacement, the ends of the telescopic plate 7 will slide relative to each other inside the rotating plate 6; the telescopic cooperation ensures that when the discharge channel 301 moves back and forth along the roller gap, the rotating plate 6 can always fit against the inner wall of the hopper 3, which not only ensures the sealing of the hopper 3, but also eliminates the dead corners of material accumulation that may be generated when the telescopic plate 7 moves.

[0063] The vibrating motor 16 drives the rotating disk 17 to rotate at high speed. The driving tooth block 1701 on the rotating disk 17 periodically engages and disengages with the driven tooth block 1801 on the fixed disk 18. When the tooth blocks engage, the floating frame 11 is forced to one side and compresses the spring 12; when the tooth blocks disengage, the floating frame 11 quickly rebounds under the restoring force of the spring 12. This high-frequency reciprocating impact causes the telescopic plate 7 to move over a wide range along the axial direction, accompanied by small-amplitude, high-frequency axial reciprocating vibration.

[0064] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0065] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
