Description

Technical Field

[0001] This utility model relates to the field of stainless steel cutting technology, specifically a fixed-length cutting device for stainless steel mesh belts. Background Technology

[0002] The stainless steel mesh belt fixed-length cutting device is a specialized automated equipment that deeply integrates three core functions: mechanical transmission, precise length control, and cutting execution. Its core working logic involves smoothly conveying a continuous roll or strip of stainless steel mesh belt to the cutting area via a conveying mechanism (such as drive rollers or conveyor belts). The cutting operation is then completed using an intermittent cutting mechanism composed of fixed and moving blades. It is widely used in the conveyor equipment manufacturing and repair industry, the food and pharmaceutical processing industry, and the automotive parts and hardware manufacturing industry. However, this type of equipment still has the following problems:

[0003] Firstly, when transporting materials, the support and guiding components such as pressure rollers and idlers often rely solely on simple physical contact to constrain and guide the transported materials and load-bearing components. However, the stainless steel mesh belt, as the core load-bearing component, is prone to deviation under long-term high-speed operation or uneven load conditions due to problems such as force imbalance and uneven wear of the mesh belt edges. Deviation causes the mesh belt to deviate from the preset shearing area. This can result in significant deviations in shearing dimensions, with cut materials of varying lengths and widths that fail to meet production specifications. In severe cases, parts of the material may exceed the shearing range, forcing the shearing blades to cut only the edges or parts of the material, generating a large amount of irregularly shaped waste.

[0004] Secondly, before the material enters the shearing process, the conveyor rollers need to generate driving force through the friction between their surface and the material to continuously convey the material to the designated shearing area. However, as the equipment operates under high load for a long time, the surface of the conveyor rollers will suffer severe wear due to continuous friction with the material. The surface texture originally used to enhance friction will gradually disappear, resulting in a significant decrease in the surface friction coefficient and a loss of sufficient driving force. This problem directly causes local slippage, making it impossible for the material to maintain a stable travel speed and precise conveying trajectory during the conveying process. Some materials will also experience irregular bending and warping deformation. When these abnormal materials enter the shearing area, due to the deviation between their actual position and shape and the preset shearing standard, errors in the shearing dimensions will occur, leading to an increase in defective products and a reduction in overall production efficiency.

[0005] Finally, during the material shearing process, when the blade acts on the material and completes the local shearing action, the unsheared material in the subsequent section will be significantly affected by the transmission and disturbance of the shearing force, resulting in violent and irregular shaking. This violent shaking may not only cause the material in the subsequent section to collide and rub against the surrounding equipment, causing scratches on the material surface and dimensional deviations, but may also interfere with the positioning accuracy of subsequent shearing processes, increasing the risks of blade wear and equipment load fluctuations.

[0006] Based on this, the present invention provides a fixed-length cutting device for stainless steel mesh belts to solve the above problems. Utility Model Content

[0007] In view of the above situation and to overcome the defects of the prior art, this utility model provides a fixed-length cutting device for stainless steel mesh belts. This utility model has a novel structure and ingenious design, and effectively solves the technical problems of easy deviation during material transportation, bending of the transported material itself, and shaking during material cutting.

[0008] A fixed-length cutting device for stainless steel mesh belt includes a machine body, a fixed blade fixedly mounted on the machine body, sliding rods fixedly mounted on both sides below the fixed blade, bearing seats movably sleeved on both sliding rods, a common sliding block fixedly sleeved on the two bearing seats, fixed rods fixedly mounted on both sides of the upper end of the sliding block, a common blade holder fixedly mounted on the two fixed rods, a movable blade fixedly mounted on the blade holder, feeding racks fixedly mounted on both sides of the machine body, mounting cylinders fixedly mounted on each feeding rack, abutment springs fixedly mounted inside the mounting cylinders, limiting plates slidably mounted inside the mounting cylinders on the outside of the abutment springs, abutment rods fixedly mounted on each limiting plate, clamping plates slidably mounted on each abutment rod, a baffle fixedly mounted at the center position of each abutment rod, and a clamping spring fixedly mounted on the clamping plate outside the baffle.

[0009] Preferably, a connecting plate is fixedly installed at the lower end of each clamping plate, an arc-shaped plate is fixedly installed at the lower end of each connecting plate, a connecting rod is rotatably installed on each arc-shaped plate, two connecting rods are connected to the same rotating plate, a fixed plate is fixedly installed on the feeding rack below the rotating plate, a toggle handle extending to the lower end of the rotating plate is installed below the fixed plate, limit frames are fixedly installed on both sides of the center position of the machine body, the same limit rod is fixedly installed inside the limit frame, and guide plates fixedly installed on the connecting plate are slidably installed on the limit rod.

[0010] Preferably, the sliding block has a sliding groove, an eccentric wheel is slidably installed in the sliding groove, a rotating rod is fixedly installed on the eccentric wheel, a driving bevel gear is fixedly sleeved on the rotating rod, a lower bevel gear is meshed with the left side of the driving bevel gear, an upper bevel gear is meshed with the right side of the driving bevel gear, a drive rod is fixedly installed on both the upper and lower bevel gears, and a driving synchronous wheel is fixedly sleeved at the end of each drive rod. The driving synchronous wheel is connected to a driven synchronous wheel via a belt. A lower roller rotatably mounted on the machine body is fixedly sleeved in the driven synchronous wheel on the left side, and an upper roller rotatably mounted on the machine body is fixedly sleeved in the driven synchronous wheel on the right side.

[0011] Preferably, a rotating frame is fixedly installed on both sides of the machine body, a screw is rotatably installed on the rotating frame, a rotating handle is fixedly installed at the end of the screw, the screw is provided with positive and negative threads, threaded blocks are respectively engaged on the positive and negative threads, a pressing rod is rotatably installed at the front and rear ends of the threaded block, the pressing rods on both sides are connected to the same pressing block, and a base plate is fixedly installed on the rotating frame below the pressing block.

[0012] Preferably, a control box is fixedly installed on one side of the machine body, a discharge plate is fixedly installed at the rear end of the machine body, a motor is connected to the end of the rotating rod, and the motor is connected to a power supply and a controller.

[0013] The present invention has the following technical effects.

[0014] 1. This utility model incorporates abutment springs, clamping springs, and guide plates to achieve a combination of structures. The abutment springs drive the abutment rods to support and hold the bottom of the material, while the clamping springs push the clamping plates to clamp the material from the side. Simultaneously, the guide plates limit the lateral movement of the material, forming a double fixation and guidance system. This effectively restricts the swaying and deviation of the material during loading and conveying, ensuring that the material remains within the preset processing path and providing a stable material state for subsequent cutting and other processes.

[0015] 2. This utility model incorporates an upper roller, a lower roller, and a drive bevel gear to achieve the meshing of the drive bevel gear, which drives the upper and lower bevel gears to rotate in opposite directions. Power is transmitted through a synchronous pulley and belt, causing the upper and lower rollers to rotate relative to each other. While clamping and conveying the material, bidirectional pressure is applied to it, which can quickly correct the bending and wrinkling of the material, achieve material flattening processing, avoid the problem of reduced cutting accuracy due to irregular material shape, and improve the quality of finished products.

[0016] 3. By incorporating a screw, threaded block, and lower pressure block, this utility model achieves that when the screw rotates, its forward and reverse threads drive the threaded blocks on both sides to move synchronously in opposite directions, causing the lower pressure rod to push the lower pressure block vertically downward. This allows the bottom of the lower pressure block to form a proper clamping between the bottom of the lower pressure block and the upper surface of the material. Combined with the bottom support structure, this forms upper and lower limits, effectively suppressing the up-and-down swaying of the material during conveying and cutting, ensuring that the material is always in a stable position in the processing area, and further improving cutting accuracy and operational stability.

Detailed Implementation

[0024] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 4The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0025] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0026] This utility model relates to a fixed-length cutting device for stainless steel mesh belts, comprising a body 1, on which a fixed blade 2 is fixedly mounted. Two sliding rods 3 are symmetrically fixedly mounted on both sides of the body 1 below the fixed blade 2. Each sliding rod 3 has a cylindrical structure. Matching bearing seats 4 are movably fitted onto each of the two sliding rods 3. The same sliding block 5 is fixedly fitted onto the outside of each of the two bearing seats 4. When the sliding block 5 is subjected to force, it can drive the two bearing seats 4 to slide synchronously along the sliding rods 3. Fixed rods 6 are fixedly mounted on both sides of the upper end of the sliding block 5, and the fixed rods 6 are perpendicular to the sliding block 5. The same blade holder 7 is fixedly mounted on the two fixed rods 6, and the blade holder 7 is fixedly equipped with… There is a moving blade 8, whose blades are parallel to those of the fixed blade 2. Feeding racks 9 are symmetrically fixed on both sides of the front end of the machine body 1. Each feeding rack 9 has a mounting cylinder 10 fixedly installed inside its inner side. The mounting cylinder 10 is a hollow, stepped cylindrical structure with a large diameter and a small hole. A through hole with a smaller inner diameter is opened at the end facing the material conveying direction. The inner edge of the through hole forms an annular step for limiting the movement of internal components. A stop spring 11 is fixedly installed inside the mounting cylinder 10. The bottom end of the stop spring 11 is fixedly installed at the bottom of the mounting cylinder 10, and the upper end of the stop spring 11 abuts against a limiting plate that is slidably installed inside the mounting cylinder 10. 12. The outer diameter of the limiting plate 12 matches the inner diameter of the main body of the mounting cylinder 10, allowing it to slide freely axially inside the mounting cylinder 10. Simultaneously, the diameter of the limiting plate 12 is larger than the inner diameter of the through hole at the front end of the mounting cylinder 10, preventing it from dislodging from the mounting cylinder 10 during sliding. A stop rod 13 is vertically fixedly installed at the center of the side of the limiting plate 12 facing the through hole. The stop rod 13 is a cylindrical metal rod with a diameter matching the inner diameter of the through hole at the front end of the mounting cylinder 10, extending through the through hole to the outside of the mounting cylinder 10. Clamping plates 14 are slidably installed on each stop rod 13. The clamping plates 14 are generally circular, and a center opening for the stop rod is provided. The sliding hole matching the connecting rod 13 can slide freely along the axial direction of the connecting rod 13. When the connecting rod 13 is located in the middle position between the clamping plate 14 and the mounting cylinder 10, a baffle 15 is fixedly sleeved on it to abut against the clamping plate 14 to open the connecting rod 13. A clamping spring 16 is fixedly installed on the clamping plate 14 outside the baffle 15. One end of the clamping spring 16 is fixed to the front end face of the mounting cylinder 10, and the other end is fixed to the side of the clamping plate 14 facing the mounting cylinder 10. Under normal conditions, the clamping spring 16 is in a naturally extended state, pushing the clamping plate 14 to extend away from the mounting cylinder 10 along the connecting rod 13 until the clamping plate 14 contacts the material.

[0027] In practical use, when loading materials into the equipment, the operator manually or through the equipment applies force to the clamping plate 14. The pre-tightened clamping spring 16 is compressed and stores elastic potential energy. After being subjected to force, the clamping plate 14 slides along the abutment rod 13 until it contacts the baffle 15 on the abutment rod 13. The force is transmitted through the baffle 15 to the abutment spring 11 inside the mounting cylinder 10, compressing it. At the same time, it drives the abutment rod 13 to retract into the mounting cylinder 10. The abutment rods 13, which were closed on both sides, open synchronously, forming a placement space suitable for the material. Then, the material is placed into the support area of ​​the abutment rod 13, ensuring that the center of the material is aligned with the support area of ​​the abutment rod 13. With the center lines of the abutment rods 13 coinciding, after the force on the clamping plate 14 is removed, the clamping spring 16 and the abutment spring 11 release potential energy synchronously. The abutment spring 11 pushes the abutment rod 13 to slide outward and connect to form a complete support rod, supporting the material. The clamping spring 16 pushes the clamping plate 14 to move towards the material until the clamping plate 14 contacts the material. The material's reverse resistance force and the spring force are balanced, achieving clamping. Finally, the material is positioned and fixed at the loading position through the dual action of being supported by the bottom support rod and clamped by the side clamping plate 14. At the same time, the swing tendency of the material is effectively limited, ensuring stable and safe operation.

[0028] As an example, a connecting plate 17 is fixedly installed at the lower end of each clamping plate 14, and an arc-shaped plate 18 is fixedly installed at the lower end of each connecting plate 17. A protruding rotating block is integrally formed on the outer wall of the arc-shaped plate 18, and a connecting rod 19 is rotatably installed on each rotating block. The rotational engagement between the rotating block and the connecting rod 19 rotatably installed on the arc-shaped plate 18 provides a stable fulcrum for the swing of the connecting rod 19. One end of the two symmetrically arranged connecting rods 19 is rotatably connected to the arc-shaped plates 18 on both sides, and the other end of the connecting rods 19 is hinged to both ends of the same rotating plate 20. Directly below the rotating plate 20, there is a fixing plate 21 fixedly installed on the frame of the loading rack 9 by a bracket. The middle of the fixing plate 21 has a through hole that matches the shape of the rotating plate 20. The through hole provides installation support for the rotating plate 20, ensuring that the rotating plate 20 can rotate around its own axis. The lower end of the rotating plate 20 is perpendicular to the axis. The device extends downwards, with a lever 22 fixedly installed at the end of the extension section. The lever 22 extends through and to the bottom of the fixed plate 21. The operator can drive the rotating plate 20 to rotate by rotating the lever 22, thereby driving the entire abutment rod 13 to complete the synchronous opening action. On both sides of the central position of the equipment body 1, limit frames 23 corresponding to the positions of the feeding rack 9 are also symmetrically fixedly installed. The two limit frames 23 are symmetrically distributed. A horizontally set limit rod 24 is fixedly installed on the limit frame 23. Two guide plates 25 are slidably fitted on the limit rod 24, and the two guide plates 25 are fixedly connected to the connecting plates 17 on both sides, so that the guide plates 25, the connecting plates 17, and the clamping plates 14 form a synchronously moving overall structure. When the clamping plates 14 clamp the material, the clamping plates 14 and the connecting plates 17 drive the guide plates 25 to clamp and guide the material synchronously to prevent deviation.

[0029] In practical use, when materials need to be placed, the operator drives the rotating plate 20 to rotate on the fixed plate 21 by turning the lever 22. The rotation of the rotating plate 20 will synchronously drive the connecting rods 19 connected at both ends to swing outward. The swing of the connecting rods 19 will then pull the arc-shaped plates 18 on both sides and the connecting plate 17 fixed to them to move in the opposite direction in sync. Finally, the clamping plate 14 at the upper end of the connecting plate 17 will open to both sides, forming a channel for materials to be placed or taken out. During this opening process, the guide plate 25 fixed to the connecting plate 17 will slide in the opposite direction along the limiting rod 24 in sync with the clamping plate 17. 4. The plates open together to avoid obstructing the placement and removal of materials. Once the materials are in place, the operator releases the lever 22, causing the rotating plate 20 to rotate in the opposite direction and drive the connecting rod 19 to swing inward. This pushes the two arc-shaped plates 18 and the connecting plate 17 to move towards each other, and the clamping plate 14 clamps the materials stably. At the same time, the guide plate 25 slides synchronously towards each other along the limiting rod 24, forming a guiding limit from both sides of the materials. This effectively restricts the lateral deviation of the materials during the conveying or processing process, ensuring that the materials always remain on the preset processing or conveying path, effectively solving the technical problem of materials easily running off-track during transportation.

[0030] As one embodiment, a sliding groove 26 is provided on the sliding block 5, and an eccentric wheel 27 is slidably installed in the sliding groove 26. The edge of the eccentric wheel 27 is tightly fitted with the inner wall of the sliding groove 26. A rotating rod 28 is fixedly installed on the eccentric wheel 27, and a driving bevel gear 29 is fixedly sleeved on the rotating rod 28. The left side of the driving bevel gear 29 meshes with a lower bevel gear 30, and the right side meshes with an upper bevel gear 31 of the same specification. The upper bevel gear 31 and the lower bevel gear 30 are symmetrically distributed with the driving bevel gear 29 as the center, and the axis of rotation of the upper bevel gear 31 and the lower bevel gear 30 are both... Perpendicular to the axis of the drive bevel gear 29, a drive rod 32 is fixedly installed at the center of both the upper bevel gear 31 and the lower bevel gear 30. The drive rod 32 is cylindrical in shape, and a drive synchronous wheel 33 is fixedly fitted at the end of each drive rod 32. The drive synchronous wheel 33 is connected to a driven synchronous wheel 35 via a belt 34. A lower roller 36 is fixedly fitted inside the driven synchronous wheel 35 on the left side and rotatably mounted on the machine body 1. An upper roller 37 is fixedly fitted inside the driven synchronous wheel 35 on the right side and rotatably mounted on the machine body 1. The upper roller 37 and the lower roller 36 have the same specifications and parallel axes.

[0031] In practical use, when transporting materials, the external drive device transmits power to the rotating rod 28 via a connection, causing the rotating rod 28 to rotate. The driving bevel gear 29, which is fixedly installed on the rotating rod 28, rotates synchronously with the rotating rod 28. Through the meshing of the tooth surfaces, it drives the upper bevel gear 31 and the lower bevel gear 30 on both sides to rotate synchronously in opposite directions. The upper bevel gear 31 and the lower bevel gear 30 transmit the rotational power to the drive rod 32. The drive rod 32 drives the driving synchronous wheel 33, which is fixed at the end, to rotate together with the drive rod 32. The driving synchronous wheel 33 rotates through a synchronous belt. The belt 34 transmits power to the driven synchronous pulley 35, which in turn drives the upper roller 37 and the lower roller 36 connected to the driven synchronous pulley 35 to rotate in opposite directions. The axes of the upper roller 37 and the lower roller 36 are parallel, so that the material entering from the feed port is stably clamped and conveyed forward with the rotation. At the same time, the upper roller 37 and the lower roller 36 form a bidirectional pressure on the material. For materials that are bent or wrinkled, under the continuous clamping, conveying and pressure, they tend to become regular and finally achieve flattening. This process effectively solves the technical problem of bent materials.

[0032] As one embodiment, rotating frames 38 are fixedly mounted on both sides of the machine body 1. A screw 39 is rotatably mounted on the rotating frame 38. One end of the screw 39 extends to the outside of the rotating frame 38, and a rotating handle 40 is fixedly mounted on the end. The middle section of the screw 39 is machined with a positive and negative thread structure 41. The positive and negative threads are symmetrical about the midpoint of the screw 39. The threads have opposite directions of rotation but the same pitch. This design allows the sliding parts on both sides to move synchronously in opposite directions when the screw 39 rotates. The positive and negative thread sections of the screw 39 are respectively engaged with... A threaded block 48 is installed, and the threaded block 48 has an internal threaded hole that matches the thread of the screw 39. Both ends of the threaded block 48 are rotatably connected to a pressure rod 42 by a pin. The four pressure rods 42 connected to the threaded blocks 48 on both sides are connected at their lower ends to the same sliding pressure block 43. The pressure block 43 is long and strip-shaped, adapted to the width of the material conveying. Four pin holes are pre-set on its top, which are respectively hinged to the lower ends of the four pressure rods 42 by pins. A base plate 44 is fixedly installed on the rotating frame 38 below the pressure block 43.

[0033] In practical use, when it is necessary to slightly clamp the material during transportation to prevent shaking, the operator rotates the handle 40 clockwise. Due to the action of the positive and negative threads 41 on the screw 39, the threaded blocks 48 on both sides will move synchronously towards each other along the screw 39. When the threaded blocks 48 move, they drive the lower pressure rods 42 at both ends to rotate around the pin shaft. The lower end of the lower pressure rods 42 pushes the lower pressure block 43 to descend vertically until the rubber pad at the bottom of the lower pressure block 43 makes slight contact with the upper surface of the material. By controlling the rotation angle of the handle 40, the distance between the lower pressure block 43 and the base plate 44 can be adjusted so that the rubber pad generates a moderate clamping force on the material. At this time, the material is restricted in the clamping space between the base plate 44 and the lower pressure block 43 during the conveying process, and the shaking in the up and down direction is effectively suppressed, ensuring that the material always passes through the conveying area in a stable posture.

[0034] As an example, a control box 45 is fixedly installed on one side of the machine body 1 to control the start-up, shutdown and operation status of the entire equipment. A discharge plate 46 is fixedly installed at the rear end of the machine body 1 to guide the finished products. A motor 47 is connected to the end of the rotating rod 28, and the motor 47 is connected to a power supply and a controller.

[0035] The working principle of this utility model is as follows: The operator starts the equipment through the control box 45 on one side of the machine body 1. The controller drives the motor 47 connected to the rotating rod 28 to operate, providing power to the whole machine. At this time, the clamping plate 14 on the feeding rack 9 is in a closed state, the upper roller 37, the lower roller 36 and the lower pressure block 43 are in a ready-to-work state, and the moving knife 8 and the fixed knife 2 are separated. Then, the operator rotates the rotating handle 40 below the feeding rack 9, which drives the rotating plate 20 and the connecting rod 19 to open the arc plate 18, the connecting plate 17 and the clamping plate 14 to both sides. At the same time, the clamping plate 14 pushes the abutment rod 13 to compress the abutment spring 11. Then, the material is placed in the support area of ​​the abutment rod 13 and the rotating handle 40 is released. The clamping spring 16 and the abutment spring 11 release potential energy, allowing the abutment rod 13 to support the material and the clamping plate 14 to clamp the material. The guide plate 25 is simultaneously reset to achieve lateral limit. After the material is loaded and positioned, the rotating rod 28 drives the active cone. Gear 29 drives the upper bevel gear 31 and the lower bevel gear 30 to rotate in opposite directions. Through the drive rod 32, the drive synchronous wheel 33 drives the drive synchronous wheel 34 and the driven synchronous wheel 35, causing the upper roller 37 and the lower roller 36 to rotate relative to each other. This clamps the material and conveys it forward, correcting its bending and wrinkles. If it is necessary to suppress the material from shaking up and down, the rotating handle 40 at the end of the screw 39 on the rotating frame 38 can be rotated. The screw 39's forward and reverse threads 41 drive the threaded block 48 to move towards each other. The lower pressure rod 42 pushes the lower pressure block 43 down, allowing the bottom rubber pad to slightly clamp the material. At the same time, the eccentric wheel 27 on the rotating rod 28 rotates with it. By engaging with the sliding groove 26 of the sliding block 5, it pushes the sliding block 5 to slide back and forth along the sliding rod 3, driving the fixed rod 6, the knife holder 7 and the moving knife 8 to move synchronously. This causes the moving knife 8 to shear relative to the fixed knife 2 on the machine body 1, completing the material cutting. Finally, the cut finished product is discharged through the discharge plate 46 at the rear end of the machine body 1.

[0036] The present invention has the following technical effects.

[0037] 1. This utility model incorporates abutment spring 11, clamping spring 16, guide plate 25, etc., so that the abutment spring 11 drives the abutment rod 13 to support and hold the bottom of the material, the clamping spring 16 pushes the clamping plate 14 to clamp the material from the side, and the guide plate 25 simultaneously limits the material laterally, forming a double fixation and guidance, which effectively limits the swing and deviation of the material during the feeding and conveying process, ensuring that the material is always in the preset processing path, and providing a stable material state for subsequent cutting and other processes.

[0038] 2. This utility model incorporates an upper roller 37, a lower roller 36, and a drive bevel gear 29, which enable the drive bevel gear 29 to mesh and drive the upper bevel gear 31 and the lower bevel gear 30 to rotate in opposite directions. The power is transmitted through the synchronous pulley and belt 34, causing the upper roller 37 and the lower roller 36 to rotate relative to each other. While clamping and conveying the material, bidirectional pressure is applied to it, which can quickly correct the bending and wrinkling of the material, achieve material flattening processing, avoid the problem of reduced cutting accuracy due to irregular material shape, and improve the quality of finished products.

[0039] 3. By incorporating a screw 39, threaded block 48, and lower pressure block 43, this utility model achieves that when the screw 39 is rotated, its forward and reverse threads 41 drive the threaded blocks 48 on both sides to move synchronously in opposite directions, causing the lower pressure rod 42 to push the lower pressure block 43 to descend vertically. This allows the bottom of the lower pressure block 43 to form a proper clamping between the bottom of the lower pressure block 43 and the upper surface of the material. Combined with the bottom support structure, this forms upper and lower limits, effectively suppressing the up-and-down swaying of the material during conveying and cutting, ensuring that the material is always in a stable position in the processing area, and further improving cutting accuracy and operational stability.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
