Description

Technical Field

[0001] This application belongs to the technical field of screen coating equipment, specifically relating to an epoxy resin spraying device for metal mesh. Background Technology

[0002] Metal mesh (such as wire mesh, fence mesh, and grid mesh) is widely used in construction, protection, and filtration. To improve its corrosion resistance, insulation, and service life, an epoxy resin coating is usually applied to the surface of the metal mesh. Spraying is one of the commonly used coating methods, which involves evenly adhering epoxy resin to the surface of the metal wire to form a protective layer.

[0003] In existing technologies, epoxy resin spraying of metal mesh typically employs a simultaneous top and bottom double-sided spraying process. Specifically, spray guns or nozzles are positioned at opposite ends of the spraying station, allowing the metal mesh to pass horizontally through the spraying area while simultaneously receiving epoxy resin spraying on both the top and bottom sides with the same or similar spraying parameters, thus achieving double-sided coverage.

[0004] The inventors discovered that the above-mentioned spraying method suffers from uneven coating thickness in practical applications. When the spray guns of the upper and lower layers operate with the same spraying force, the epoxy resin sprayed on the upper layer experiences greater impact force during its descent due to gravity than the original spraying force. This causes the resin on the upper layer to more easily penetrate the mesh or flow downwards along the wire. This dripping or flowing resin washes over and covers the coating on the lower surface that has not yet firmly adhered, causing the lower coating to be diluted, thinned, or even partially missing. Ultimately, this results in a "thick on top, thin on bottom" coating distribution defect, causing poor epoxy resin spraying effect and affecting the overall anti-corrosion performance and service life of the metal mesh. Summary of the Invention

[0005] This application provides an epoxy resin spraying device for metal mesh, which aims to ensure the spraying effect of epoxy resin on both sides of the metal mesh, and to ensure its overall anti-corrosion performance and service life.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: An epoxy resin spraying apparatus for metal mesh is provided, comprising: A workbench is used to be fixedly mounted on a support surface and has a structure that extends in the front-to-back direction; A horizontal conveying assembly is set on the worktable to drive the metal mesh to move horizontally in the front-to-back direction, forming a first spraying section with the front and back sides of the metal mesh facing upwards and downwards respectively; A steering component is disposed on the upper side of the flat conveying component to drive the metal mesh to turn initially, forming a second spraying section located directly above the first spraying section, with the front and back sides of the metal mesh facing downwards and upwards respectively; A reversing assembly, disposed above the steering assembly, is used to drive the metal mesh to turn again, so that the front and back sides of the metal mesh face upwards and downwards respectively, and move forward in a translating motion; and A spraying assembly for containing epoxy resin includes a first spraying member located between the first spraying section and the second spraying section for spraying epoxy resin onto the first spraying section, and a second spraying member located above the second spraying section for spraying epoxy resin onto the second spraying section.

[0007] In one possible implementation, the flat-feed component includes: A drive roller is rotatably mounted on the worktable along the width direction of the metal mesh and is connected to a rotation drive component; and Two pressure rollers are arranged side by side on the upper side of the worktable in the front-to-back direction, and both are rotatably connected to the worktable in the width direction of the metal mesh through elastic pre-tightening members, so that a matching gap is formed between the rear pressure roller and the drive roller, allowing the metal mesh to pass through, and the metal mesh passes through the underside of the front pressure roller, forming the first spraying section between the two pressure rollers and maintaining a horizontal posture.

[0008] In one possible implementation, both ends of the pressure roller have arc-shaped connecting frames that are rotatably connected to it along the width direction of the metal mesh; the connecting frames are located on the outer side of the worktable facing the width direction of the metal mesh, and both ends of the connecting frames are connected to the worktable through the elastic preload; The elastic preload includes: A fixed housing is fixedly disposed on the outer side of the worktable, and has a guide groove that opens outward and extends vertically; and The slider is slidably disposed in the guide groove in the up-down direction, and is detachably connected to the end of the connecting frame; A spring is provided between the slider and the inner top surface of the guide groove, and the spring is used to drive the slider to move downward relative to the fixed shell; Furthermore, on the same side of the worktable, two adjacent sliders in the front-to-back direction are connected by a connecting rod, and the connecting rod is slidably connected to the worktable in the up-down direction so that the sliders are on the same horizontal plane.

[0009] In one possible implementation, the steering component includes: A front reversing roller, rotatably positioned above the flat conveying assembly along the width direction of the metal mesh, allows the metal mesh passing through the flat conveying assembly to bypass and move backward, so that the front of the metal mesh changes from facing upward to facing downward; and The rear deflector roller is rotatably disposed behind the front deflector roller along the width direction of the metal mesh, and is used for the metal mesh that passes around the front deflector roller to pass around and translate forward, forming the second spraying section between the front deflector roller and the rear deflector roller; The lower edge of the rear reversing roller is on the same horizontal plane as the upper edge of the front reversing roller, so that the second spraying section remains horizontal.

[0010] In one possible implementation, the reciprocating component includes: A suspension roller, rotatably mounted above the rear deflector roller along the width direction of the metal mesh, is used for the metal mesh to pass around the rear deflector roller and translate forward; and A directional roller, rotatably disposed on the front side of the flat conveying assembly along the width direction of the metal mesh, is used to allow the metal mesh that passes around the suspension roller to bypass and move forward.

[0011] In one possible implementation, the epoxy resin spraying apparatus further includes: A suspension is provided above the worktable, and both the rear deflector roller and the suspension roller are rotatably mounted on the suspension. The suspension has a turntable rotatably connected to its side, and the turntable has a suspension rod extending vertically along its rotation axis for connecting to the top wall above the workbench, so that the suspension is set at an angle or vertically.

[0012] In one possible implementation, the spraying assembly includes: A positioning platform is fixedly installed on the outer side of the workbench facing the width direction of the metal mesh, and a storage tank for containing epoxy resin is fixedly installed on it. An upper feeding box is fixedly installed on the side of the positioning platform facing the workbench and above the second spraying section; the upper feeding box is connected to the storage tank via a pump, and the lower side of the upper feeding box has multiple upper spray nozzles to form the first spraying component; and The lower feed box is fixedly disposed on the side of the positioning platform facing the workbench and is located between the second spraying section and the first spraying section; the lower feed box has an upward opening to allow epoxy resin passing through the second spraying section to enter, and the lower side of the lower feed box has a plurality of lower nozzles to form the second spraying component.

[0013] In one possible implementation, the upper side of the lower feed box has a collection hopper communicating with its opening, and the collection hopper has a structure in which the diameter gradually increases from bottom to top.

[0014] In one possible implementation, the upper side of the workbench has an open-topped recycling bin; the recycling bin is located directly below the first spraying section to collect epoxy resin passing through the first spraying section.

[0015] In one possible implementation, the epoxy resin spraying apparatus further includes: Two sets of air blowing components are respectively disposed between the first spraying section and the second spraying section, and on the upper side of the second spraying section; each set of air blowing components includes two air blowing components arranged side by side in the front-rear direction, each air blowing component facing the upper side of the corresponding second spraying section or the upper side of the first spraying section; and An air pump, connected to each of the air blowing elements, is used to deliver gas to the air blowing elements.

[0016] In this embodiment, a flat-feed assembly is mounted on a worktable to drive the metal mesh to move horizontally in the front-to-back direction, forming a first spraying section where the front and back sides of the metal mesh face upwards and downwards, respectively. A steering assembly is mounted above the flat-feed assembly to drive the metal mesh to make an initial turn, causing it to enter a second spraying section located directly above the first spraying section; in this section, the front and back sides of the metal mesh face downwards and upwards, respectively, which is the opposite of the orientation in the first spraying section. A reversing assembly is mounted above the steering assembly to drive the metal mesh to turn again, restoring it to its initial state where the front and back sides face upwards and downwards, and continuing to move forward horizontally. The spraying assembly includes a first spraying component and a second spraying component, wherein the first spraying component is mounted between the first and second spraying sections and is used to spray epoxy resin onto the upper surface of the metal mesh (i.e., the original upper side) in the first spraying section; the second spraying component is mounted above the second spraying section and is used to spray epoxy resin onto the upper surface of the metal mesh (i.e., the original lower side) in the second spraying section.

[0017] The aforementioned structure achieves time-sharing and side-by-side spraying of both sides of the metal mesh through two rotations. Its working principle is as follows: the metal mesh first passes through the first spraying section with its front side facing upwards, where the first spraying component sprays its front side; then, after being flipped by the rotating assembly, the original back side faces upwards as it enters the second spraying section, where the second spraying component sprays its back side. The two spraying processes are performed independently at different locations, and the surfaces to be coated are always facing upwards during spraying, allowing the epoxy resin to adhere and level naturally under gravity, preventing it from penetrating the mesh or flowing to the other side due to the downward spray. After completing the back side spraying, the reversing assembly flips again, restoring the metal mesh to its initial position for subsequent processes.

[0018] The epoxy resin spraying device for metal mesh provided in this embodiment, compared with the prior art, can decompose the spraying of the front and back sides of the metal mesh into two independent processes through two turns, so that each side is sprayed in an upward position. It fundamentally avoids the problem of erosion and thinning of the lower coating caused by the upper resin dripping due to gravity in the traditional simultaneous top and bottom spraying process, eliminating the "thick top, thin bottom" coating distribution defect. This not only ensures the uniformity of epoxy resin coating thickness and adhesion on both sides of the metal mesh, significantly improving the coating's corrosion resistance and service life, but also maintains operational efficiency through continuous horizontal feeding and turning, providing reliable process equipment for high-quality surface treatment of metal mesh.

[0025] Please refer to the following: Figures 1 to 14 The epoxy resin spraying apparatus for metal mesh provided in this application will now be described. The epoxy resin spraying apparatus proposed in this application includes a worktable 1, a horizontal feeding assembly 2, a steering assembly 3, a reciprocating assembly 4, and a spraying assembly 5.

[0026] The workbench 1 is fixedly mounted on the support surface and has a structure that extends in the front-to-back direction, forming the installation foundation and working platform of the entire device.

[0027] The flat conveyor 2 is set on the workbench 1 and is used to drive the metal mesh to move horizontally in the front and back direction, forming the first spraying section I with the front and back sides of the metal mesh facing the upper and lower sides respectively.

[0028] The steering component 3 is located on the upper side of the flat conveying component 2 and is used to drive the metal mesh to turn initially, forming the second spraying section II, which is located directly above the first spraying section I and has the front and back sides of the metal mesh facing downwards and upwards, respectively.

[0029] The reversing component 4 is located on the upper side of the steering component 3 and is used to drive the metal mesh to turn again so that the front and back sides of the metal mesh face the upper and lower sides respectively, and continue to move forward.

[0030] The spraying assembly 5 is used to contain epoxy resin and includes a first spraying component and a second spraying component.

[0031] The first spraying component is located between the first spraying section I and the second spraying section II, and is used to spray epoxy resin onto the first spraying section I from above; and the second spraying component is located on the upper side of the second spraying section II, and is used to spray epoxy resin onto the second spraying section II from above.

[0032] In this embodiment, the flat conveying component 2 is mounted on the worktable 1 and is used to drive the metal mesh to move horizontally in the front-to-back direction, forming a first spraying section I with the front and back sides of the metal mesh facing upwards and downwards, respectively. The steering component 3 is mounted above the flat conveying component 2 and is used to drive the metal mesh to make an initial turn, causing it to enter a second spraying section II located directly above the first spraying section I; in this section, the front and back sides of the metal mesh face downwards and upwards, respectively, which is the opposite of the orientation in the first spraying section I. The reversing component 4 is mounted above the steering component 3 and is used to drive the metal mesh to turn again, restoring it to its initial state with the front and back sides facing upwards and downwards, and continuing to move forward horizontally. The spraying assembly 5 includes a first spraying component and a second spraying component, wherein the first spraying component is disposed between the first spraying section I and the second spraying section II, and is used to spray epoxy resin onto the surface of the metal mesh (i.e. the original upper side) in the first spraying section I; the second spraying component is disposed on the upper side of the second spraying section II, and is used to spray epoxy resin onto the surface of the metal mesh (i.e. the original lower side) in the second spraying section II.

[0033] The aforementioned structure achieves time-sharing and side-by-side spraying of both sides of the metal mesh through two rotations. Its working principle is as follows: the metal mesh first passes through the first spraying section I with its front side facing upwards, where the first spraying component sprays its front side; then, after being flipped by the turning component 3, the original back side faces upwards as it enters the second spraying section II, where the second spraying component sprays its back side. The two spraying processes are performed independently at different locations, and the surfaces to be coated are always facing upwards during spraying, allowing the epoxy resin to adhere and level naturally under gravity, preventing it from penetrating the mesh or flowing to the other side due to the downward spray. After completing the back side spraying, the reversing component 4 flips again, restoring the metal mesh to its initial posture for subsequent processes.

[0034] The epoxy resin spraying device for metal mesh provided in this embodiment, compared with the prior art, can decompose the spraying of the front and back sides of the metal mesh into two independent processes through two turns, so that each side is sprayed in an upward position. It fundamentally avoids the problem of erosion and thinning of the lower coating caused by the upper resin dripping due to gravity in the traditional simultaneous top and bottom spraying process, eliminating the "thick top, thin bottom" coating distribution defect. This not only ensures the uniformity of epoxy resin coating thickness and adhesion on both sides of the metal mesh, significantly improving the coating's corrosion resistance and service life, but also maintains operational efficiency through continuous horizontal feeding and turning, providing reliable process equipment for high-quality surface treatment of metal mesh.

[0035] In some embodiments, such as Figures 1 to 4 As shown, the flat conveying assembly 2 includes a drive roller 21 and two pressure rollers 22.

[0036] The drive roller 21 is rotatably mounted on the worktable 1 along the width direction of the metal mesh and is connected to a rotation drive component 211. In this embodiment, the rotation drive component 211 includes a rotation motor fixedly mounted on the inner side of the worktable 1, and a drive gear and a driven gear respectively mounted on the rotation motor and the drive roller 21 and meshing with each other.

[0037] Two pressure rollers 22 are arranged side by side on the upper side of the worktable 1 in the front-to-back direction, and both are rotatably connected to the worktable 1 in the direction of the width of the metal mesh through the elastic pre-tightening member 6, so that a matching gap is formed between the rear pressure roller 22 and the drive roller 21, allowing the metal mesh to pass through, and allowing the metal mesh to pass through the lower side of the front pressure roller 22, forming the first spraying section I, which is located between the two pressure rollers 22 and maintains a horizontal posture.

[0038] By adopting the above technical solution, the drive roller 21 rotates under the drive component 211, providing forward power for the metal mesh. Based on this, the pressure roller 22 presses down on the drive roller 21 through the elastic pre-tightening member 6, forming a stable clamping force (along the thickness direction) on the metal mesh, preventing slippage of the metal mesh on the outer wall of the drive roller 21. In other words, the metal mesh passes forward between the rear pressure roller 22 and the drive roller 21, and then passes under the front pressure roller 22, thus forming a horizontally unfolded first spraying section I in the area between the two pressure rollers 22, ensuring the flatness and consistency of the spraying area.

[0039] In some embodiments, such as Figure 4 and Figure 5 As shown, both ends of the pressure roller 22 have connecting frames 221. These connecting frames 221 are arc-shaped, and the center of the arc-shaped body is rotatably connected to the pressure roller 22 along the width direction of the metal mesh.

[0040] The connecting frame 221 is located on the outer side of the workbench 1 facing the width direction of the metal mesh, and both ends of the connecting frame 221 are connected to the workbench 1 through the aforementioned elastic pretensioner 6. Based on this, the elastic pretensioner 6 includes a fixed shell 61 and a slider 62.

[0041] The fixed shell 61 is fixedly installed on the outer side of the workbench 1, and has a guide groove 611 that is open to the outside and extends in the vertical direction.

[0042] The slider 62 is slidably disposed in the guide groove 611 in the up-down direction, and it is detachably connected to the end of the connecting frame 221.

[0043] A spring 621 is provided between the slider 62 and the inner top surface of the guide groove 611; in actual use, the spring 621 is used to drive the slider 62 to move downward relative to the fixed shell 61.

[0044] On the same side of the worktable 1, two adjacent sliders 62 in the front-to-back direction are connected by a connecting rod 622, and the connecting rod 622 is slidably connected to the worktable 1 in the up-down direction so that the sliders 62 are always on the same horizontal plane under the action of the connecting rod 622.

[0045] The design of the elastic preload 6 enables precise adjustment and synchronous control of the pressure of the pressure roller 22. Its beneficial effects are as follows: the spring 621 pushes the slider 62 downwards, transmitting the elastic force to the pressure roller 22 through the connecting frame 221, causing it to press against the drive roller 21; by replacing the spring 621 with one of different stiffness or adjusting the initial position of the slider 62, the clamping force of the pressure roller 22 on the metal mesh can be changed to accommodate metal meshes of different thicknesses or materials. Simultaneously, the connecting rod 622 connects the two sliders 62, ensuring that the pressure of the two pressure rollers 22 is balanced and synchronized, preventing the metal mesh from shifting or wrinkling due to uneven pressure on one side, and preventing the aforementioned first spraying section I from tilting.

[0046] In some embodiments, such as Figure 6 , Figure 8 and Figure 10 As shown, the steering assembly 3 includes a front deflector roller 31 and a rear deflector roller 32.

[0047] The front reversing roller 31 is rotatably positioned above the flat conveying assembly 2 along the width direction of the metal mesh (specifically, it is positioned directly above the front pressure roller 22, and the front edge of the front reversing roller 31 and the front edge of the front pressure roller 22 are tangent to the same vertical plane), so that the metal mesh passing through the flat conveying assembly 2 can bypass and move backward, so that the front of the metal mesh changes from facing upward to facing downward.

[0048] The rear deflector roller 32 is rotatably disposed behind the front deflector roller 31 along the width direction of the metal mesh, so that the metal mesh that passes around the front deflector roller 31 can pass around and move forward to form the second spraying section II between the front deflector roller 31 and the rear deflector roller 32.

[0049] The lower edge of the rear reversing roller 32 is on the same horizontal plane as the upper edge of the front reversing roller 31, so that the second spraying section II remains in a horizontal position.

[0050] The steering assembly 3 achieves spatial flipping and horizontal conveying of the metal mesh through the cooperation of two reversing rollers. Its working principle is as follows: the metal mesh passes over the front reversing roller 31, changing its front side from facing up to facing down; then it passes under the rear reversing roller 32, changing its direction of movement from backward to forward, at which point the reverse side of the metal mesh faces up, forming the second spraying section II. The horizontal alignment design of the edges of the front reversing roller 31 and the rear reversing roller 32 ensures that the metal mesh in the second spraying section II maintains a horizontal posture, providing a stable working surface for subsequent spraying.

[0051] In some embodiments, such as Figure 7 , Figure 8 and Figure 10 As shown, the reciprocating assembly 4 includes a suspension roller 41 and a directional roller 42.

[0052] The suspension roller 41 is rotatably positioned above the rear deflector roller 32 along the width direction of the metal mesh, so that the metal mesh passing around the rear deflector roller 32 can pass around and move forward sideways.

[0053] The directional roller 42 is rotatably disposed on the front side of the flat conveying assembly 2 along the width direction of the metal mesh, and is used to allow the metal mesh that passes over the suspension roller 41 to pass around and move forward.

[0054] The reversing assembly 4 achieves a secondary flipping and posture restoration of the metal mesh through the cooperation of the suspension roller 41 and the orientation roller 42. Its working principle is as follows: after passing through the rear reversing roller 32, the metal mesh moves upwards around the suspension roller 41, changing its originally upward-facing reverse side to downward-facing; after moving forward around the orientation roller 42, the metal mesh returns to its initial posture with the front side facing upwards, and continues to move forward to the next process. This design ensures that the metal mesh can be output in a uniform posture after double-sided coating, facilitating subsequent winding or stacking.

[0055] In some embodiments, such as Figure 1 , Figure 8 and Figure 10 As shown, the epoxy resin spraying device also includes a suspension 7.

[0056] The suspension 7 is used to be set above the worktable 1, and the rear deflector roller 32 and the suspension roller 41 are both rotatably mounted on the suspension 7.

[0057] The suspension 7 has a turntable 71 rotatably connected to its side, and the turntable 71 has a suspension rod 72 extending vertically along its rotation axis for connecting to the top wall above the workbench 1, so that the suspension 7 is inclined or vertically arranged relative to the roof surface of the building.

[0058] In actual use, by rotating the turntable 71 and locking the suspension rod 72, the overall tilt angle of the suspension 7 can be adjusted, thereby changing the relative position of the rear reversing roller 32 and the suspension roller 41 to adapt to the tension requirements of metal mesh of different specifications; at the same time, the suspended installation method of the suspension 7 frees up the space above the workbench 1, making it easier for operators to observe and maintain.

[0059] In some embodiments, such as Figures 11 to 14 As shown, the spraying assembly 5 includes a positioning platform 51, an upper feeding box 52, and a lower feeding box 53.

[0060] The positioning platform 51 is fixedly installed on the outer side of the workbench 1 facing the width direction of the metal mesh, and a storage tank 10 for containing epoxy resin is fixedly installed on it.

[0061] The upper feeding box 52 is fixedly installed on the side of the positioning platform 51 facing the workbench 1 and is located above the second spraying section II; the upper feeding box 52 is connected to the storage tank 10 through the material pump 20, and the lower side of the upper feeding box 52 has multiple upper spray nozzles 521 to form the aforementioned first spraying component.

[0062] The lower feed box 53 is fixedly installed on the side of the positioning table 51 facing the worktable 1, and is located between the second spraying section II and the first spraying section I.

[0063] The lower feed box 53 has an upward opening for epoxy resin to enter through the second spraying section II, and the lower side of the lower feed box 53 has a plurality of lower nozzles 531 to form the aforementioned second spraying component.

[0064] The spraying assembly 5 achieves independent material supply to the two spraying sections through the separate arrangement of the upper feed box 52 and the lower feed box 53. Its working principle is as follows: the pump 20 transports the epoxy resin from the storage tank 10 to the upper feed box 52, where it is sprayed downwards through the upper nozzle 521 onto the metal mesh surface (i.e., the reverse side) of the second spraying section II; epoxy resin dripping or splashing from the second spraying section II falls into the opening of the lower feed box 53, is collected and reused, and then sprayed downwards through the lower nozzle 531 onto the metal mesh surface (i.e., the front side) of the first spraying section I. This design not only achieves double-sided spraying but also reduces resin waste and lowers operating costs through the collection function of the lower feed box 53.

[0065] In some embodiments, such as Figure 11 and Figure 14 As shown, the upper side of the lower feeding box 53 has a collection hopper 532 connected to its open opening, and the collection hopper 532 has a structure in which the diameter gradually increases from bottom to top.

[0066] The hopper 532 is designed to improve the efficiency of collecting falling resin. Its beneficial effects are: the gradually increasing opening of the hopper 532 creates a larger receiving area, which can effectively capture the resin dripping from the second spraying section II and reduce splash loss; at the same time, the funnel-shaped guiding surface allows the collected resin to flow smoothly into the lower feed box 53, avoiding accumulation or blockage at the opening edge.

[0067] In some embodiments, such as Figure 2 and Figure 9 As shown, the upper side of the workbench 1 has an open-topped recycling bin 8, which is located directly below the first spraying section I and is embedded in the upper side of the workbench 1 to collect the epoxy resin falling through the first spraying section I.

[0068] The recycling bin 8 is designed to collect dripping resin from the first spraying section I. Its advantages are: during spraying in the first spraying section I, some epoxy resin may drip without adhering to the metal mesh; the recycling bin 8 collects this resin, preventing contamination of the workbench 1 and the surrounding environment; the collected resin can be regularly cleaned and recycled, further improving material utilization.

[0069] In some embodiments, such as Figure 1 , Figure 11 and Figure 12 As shown, the epoxy resin spraying device also includes two sets of air blowing components 9 and an air pump 30.

[0070] Two sets of air blowing components 9 are respectively disposed between the first spraying section I and the second spraying section II, and on the upper side of the second spraying section II. Each set of air blowing components 9 includes two air blowing components 9 arranged side by side in the front-back direction, and each air blowing component 9 faces the upper side of the corresponding second spraying section II or the upper side of the first spraying section I.

[0071] The air pump 30 is connected to each air blowing element 9 and is used to deliver gas to the air blowing element 9.

[0072] The air blowing element 9 is designed to assist in controlling the uniformity of the coating. Its beneficial effects are as follows: the air blowing element 9, positioned between the first spraying section I and the second spraying section II, can blow airflow onto the surface of the metal mesh after spraying in the first spraying section I, accelerating solvent evaporation, promoting initial coating curing, and preventing coating contamination during subsequent flipping; the air blowing element 9, positioned above the second spraying section II, can immediately smooth the coating after spraying, eliminating orange peel or sagging phenomena and improving surface quality. Since both sets of air blowing elements 9 are arranged side-by-side in the front-back direction, it ensures that the airflow coverage area can be adapted to the actual spraying width.

[0073] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
