Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, specifically a spraying device for processing highway corrugated guardrail panels. Background Technology

[0002] Highway guardrails are continuous structures made of corrugated steel guardrail panels spliced ​​together and supported by main posts. When a vehicle collides with them, the corrugated steel guardrail panels have good impact resistance and energy absorption properties, making them less likely to be destroyed. At the same time, they can provide good protection for vehicles and drivers and passengers. The guardrails on both sides of existing highways are prone to rust and damage due to being exposed to various harsh environments over the years. Generally, a spraying device is used to spray a coating onto the guardrail panels during the production and processing of the guardrail panels.

[0003] For example, application number CN202122360793.6 discloses a spraying device for processing highway corrugated guardrail panels, including a base, an air extraction box, and a flipping structure. A spraying box is installed on the top surface of the base, and an air extraction box is installed on the top surface of the spraying box. A dustproof net is installed through one side surface of the air extraction box, and a micro motor is installed on one side surface of the spraying box via a support plate. The flipping structure is installed inside the spraying box. This utility model, by installing a lead screw, an air pump, an air extraction pipe, a heating box, a moving base, and a hot air nozzle, draws in air through the air pump and passes it into the air extraction pipe. The air then enters the heating box for heating and is sprayed out from the hot air nozzle through the exhaust hose. The lead screw and the moving base work together to dry various parts of the guardrail panel, achieving automatic drying and shaping of the guardrail panel. This prevents the coating from peeling off due to insufficient drying and shaping, ensuring the quality of the guardrail panel spraying.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem of manual flipping after spraying due to the lack of an automatic flipping structure, which consumes manpower and time, there are still some drawbacks. During use, because the spray box is sealed during spraying, a large amount of atomized paint will be present in the spray box when the spraying device atomizes the paint and sprays it onto the guardrail. Therefore, after spraying, it cannot be opened rashly to prevent the atomized paint from drifting into the work area and being inhaled by users over a long period of time, causing health problems. However, letting the atomized paint settle and dissipate naturally is too time-consuming, thus greatly reducing production efficiency. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a spraying device for processing highway corrugated guardrail panels. This device has the advantage of quickly eliminating atomized paint, solving the problem that because the spraying box is sealed during spraying, a large amount of atomized paint remains in the spraying box when spraying the guardrail panels. Consequently, after spraying, the box cannot be opened hastily to prevent the atomized paint from drifting into the work area and accumulating in the user's body over a long period, causing health problems. However, letting the atomized paint settle and dissipate naturally is too time-consuming, thus greatly reducing production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spraying device for processing highway corrugated guardrail panels, comprising a spraying box, a lead screw, a motor, a spraying device, a clamping device, and a feeding device. Both sides of the lead screw are movably connected to the top of both sides of the inner wall of the spraying box via pins. The left side of the motor is fixedly connected to the top of the right side of the spraying box. The output end of the motor extends through to the right side of the inner wall of the spraying box and is fixedly connected to the right side of the lead screw. The inner wall of the spraying device is threadedly connected to the surface of the lead screw. The outer side of the clamping device is fixedly connected to both sides of the inner wall of the spraying box. The bottom of the feeding device is fixedly connected to the right side of the top of the spray box. The output end of the feeding device passes through a conduit to the top of the inner wall of the spray box and is fixedly connected to the input end of the spraying device. An air pump is fixedly connected to the right side of the back of the spray box. An anti-fogging box is fixedly connected to the input end of the air pump. The front of the anti-fogging box is fixedly connected to the back of the spray box. A connecting hole is opened on the rear side of the inner wall of the spray box. There are two connecting holes. The rear side of the inner wall of the connecting hole extends to the left side of the front side of the inner wall of the anti-fogging box. A uniform suction mechanism is fixedly connected to the inner wall of the connecting hole.

[0007] As a preferred embodiment of this utility model, the uniform suction mechanism includes an L-shaped tube, one end of the surface of the L-shaped tube is fixedly connected to the inner wall of the connecting hole, a shaped tube is fixedly connected to the rear side of the inner wall of the spray box, a suction hole is opened on the front side of the shaped tube, a plurality of suction holes are provided and are evenly distributed, and the outer side of the L-shaped tube is fixedly connected to both sides of the inner wall of the shaped tube.

[0008] As a preferred embodiment of this utility model, an insertion groove is provided on the right side of the top of the defogging box, and a filter cotton plate is slidably connected to the inner wall of the insertion groove.

[0009] As a preferred embodiment of this utility model, a perforated plate is fixedly connected to the left side of the interior of the fog-extinguishing box, and the perforated plate is provided in a plurality of such perforated plates and is distributed at equal rectangular intervals.

[0010] As a preferred embodiment of this invention, a raised plate is movably connected to the bottom of the filter cotton plate, and the surface of the raised plate is fixedly connected to the inner wall of the defogging box.

[0011] As a preferred embodiment of this utility model, a drain valve is fixedly connected to the left side of the bottom back of the spray box, and the drain valve is connected to the inner wall of the spray box.

[0012] As a preferred embodiment of this invention, the back of the defogging box is provided with an installation groove, and a transparent observation window is fixedly connected to the inner wall of the installation groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up an air pump and an anti-fogging box, first starts the air pump after the guardrail panel is painted in the spray box, drawing air out of the anti-fogging box and creating a negative pressure inside. This negative pressure is then transmitted through the connecting hole, causing the suction mechanism to generate suction, ultimately drawing the atomized paint from the spray box into the anti-fogging box. This solves the problem that because the spray box is sealed during spraying, a large amount of atomized paint accumulates in the box when spraying the guardrail panel. This prevents the box from being opened immediately after spraying to avoid the atomized paint drifting into the work area and accumulating and causing health problems for users. However, letting the atomized paint settle and dissipate naturally is too time-consuming, significantly reducing production efficiency. This invention achieves the effect of quickly eliminating atomized paint.

[0015] 2. This utility model, by setting up a uniform suction mechanism, when the air pump is running, draws the air out of the defogging box, creating a negative pressure inside. This negative pressure is transmitted through the L-shaped tube in the connecting hole to the I-shaped tube, thereby causing the multiple suction holes on the I-shaped tube to generate suction. After the spraying device sprays the guardrail, the excess atomized paint in the spraying box is quickly sucked into the defogging box, thus preventing the atomized paint from drifting into the work area and accumulating, causing health problems for users due to long-term inhalation.

[0016] 3. This utility model, by setting an insertion slot and a filter cotton plate, allows the filter cotton plate to be inserted into the defogging box before the atomized paint in the spray box is sucked into the defogging box by the air pump. Then, when the atomized paint approaches the input end of the air pump, the atomized paint is first filtered by the filter cotton plate, which intercepts the paint in the atomized paint on the filter cotton plate, thereby preventing the paint from entering the air pump and adhering to the inside, causing pollution or blockage on the parts and reducing their performance.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, this utility model provides a spraying device for processing highway corrugated guardrail panels, including a spraying box 1, a lead screw 2, a motor 3, a spraying device 4, a clamping device 5, and a feeding device 6. Both sides of the lead screw 2 are movably connected to the top of both sides of the inner wall of the spraying box 1 via pins. The left side of the motor 3 is fixedly connected to the top of the right side of the spraying box 1. The output end of the motor 3 extends through to the right side of the inner wall of the spraying box 1 and is fixedly connected to the right side of the lead screw 2. The inner wall of the spraying device 4 is threadedly connected to the surface of the lead screw 2. The outer side of the clamping device 5 is fixedly connected to both sides of the inner wall of the spraying box 1. The bottom of the feeding device 6 is fixedly connected to the right side of the top of the spray box 1. The output end of the feeding device 6 passes through a conduit to the top of the inner wall of the spray box 1 and is fixedly connected to the input end of the spraying device 4. An air pump 7 is fixedly connected to the right side of the back of the spray box 1. An anti-fogging box 8 is fixedly connected to the input end of the air pump 7. The front of the anti-fogging box 8 is fixedly connected to the back of the spray box 1. A connecting hole 9 is opened on the rear side of the inner wall of the spray box 1. There are two connecting holes 9. The rear side of the inner wall of the connecting hole is opened to the left side of the front side of the inner wall of the anti-fogging box 8. A uniform suction mechanism 10 is fixedly connected to the inner wall of the connecting hole 9.

[0023] refer to Figure 2 The suction mechanism 10 includes an L-shaped tube 101. One end of the surface of the L-shaped tube 101 is fixedly connected to the inner wall of the connecting hole 9. A shaped tube 102 is fixedly connected to the rear side of the inner wall of the spray box 1. A suction hole 103 is opened on the front side of the shaped tube 102. Several suction holes 103 are provided and are evenly distributed. The outer side of the L-shaped tube 101 is fixedly connected to both sides of the inner wall of the shaped tube 102.

[0024] As a technical optimization of this utility model, by setting up a uniform suction mechanism 10, when the air pump 7 is running, it draws the air out of the defogging box 8, creating a negative pressure inside. The negative pressure inside the defogging box 8 is transmitted through the L-shaped tube 101 in the connecting hole 9 to the eye-shaped tube 102, thereby causing the multiple suction holes 103 on the eye-shaped tube 102 to generate suction. Subsequently, after the spraying device 4 sprays the guardrail, the excess atomized paint in the spraying box 1 is quickly sucked into the defogging box 8, thus preventing the atomized paint from drifting into the work area and accumulating, causing health problems for users due to long-term inhalation.

[0025] refer to Figure 3 An insertion slot 11 is provided on the right side of the top of the defogging box 8, and a filter cotton plate 12 is slidably connected to the inner wall of the insertion slot 11.

[0026] As a technical optimization of this utility model, by setting an insertion slot 11 and a filter cotton plate 12, before the atomized paint in the spray box 1 is sucked into the defogging box 8 by the vacuum pump 7, the filter cotton plate 12 is first inserted into the defogging box 8 through the insertion slot 11. Then, when the atomized paint approaches the input end of the vacuum pump 7, the atomized paint is first filtered by the filter cotton plate 12, and the paint in the atomized paint is intercepted on the filter cotton plate 12, thereby preventing the paint from entering the vacuum pump 7 and adhering to the inside, causing pollution or blockage on the parts and reducing their performance.

[0027] refer to Figure 3 The left side of the interior of the defogging box 8 is fixedly connected to a perforated plate 13, and there are several perforated plates 13 that are distributed at equal rectangular intervals.

[0028] As a technical optimization of this utility model, by setting the perforated plate 13, when the atomized paint inside the spray box 1 is sucked into the defogging box 8, the atomized paint will simultaneously come into contact with the perforated plate 13. Subsequently, the atomized paint enters the defogging box 8 through the perforated plate 13, increasing the contact area between the atomized paint and the inner wall of the defogging box 8. This allows the atomized paint to quickly convert from an atomized state to a liquid state, thereby reducing the filtration volume of the filter cotton plate 12 and improving the service life of the filter cotton plate 12.

[0029] refer to Figure 3 A raised plate 14 is movably connected to the bottom of the filter cotton plate 12, and the surface of the raised plate 14 is fixedly connected to the inner wall of the defogging box 8.

[0030] As a technical optimization of this utility model, by setting a raised plate 14, when the filter cotton plate 12 is inserted into the defogging box 8 through the insertion groove 11, the filter cotton plate 12 will come into contact with the raised plate 14 in the defogging box 8. Subsequently, through the raised plate 14, the liquid paint in the defogging box 8 cannot soak into the filter cotton plate 12, thus accelerating the wear of the filter cotton plate 12 and further improving the service life of the filter cotton plate 12.

[0031] refer to Figure 3 A drain valve 15 is fixedly connected to the bottom left side of the back of the spray box 1, and the drain valve 15 is connected to the inner wall of the spray box 1.

[0032] As a technical optimization of this utility model, by setting a drain valve 15, when the liquid paint in the defogging box 8 accumulates to a certain extent, it can be discharged through the drain valve 15, thereby preventing the liquid paint in the defogging box 8 from accumulating too much and overflowing through the connecting hole 9 into the shaped tube 102, thus affecting recycling.

[0033] refer to Figure 3 The back of the defogging box 8 is provided with a mounting groove 16, and a transparent observation window 17 is fixedly connected to the inner wall of the mounting groove 16.

[0034] As a technical optimization of this utility model, by setting the installation slot 16 and the transparent observation window 17, in daily use, the user can check whether the liquid paint accumulated in the defogging box 8 is about to overflow the connecting hole 9 through the transparent observation window 17 in the installation slot 16, and then determine whether the drain valve 15 needs to be opened, thereby improving the user's ease of operation.

[0035] The working principle and usage process of this utility model are as follows: When it is necessary to spray paint the guardrail, first, paint is poured into the feeding device 6, then the spray box 1 is opened, and the guardrail is fixedly clamped by the clamping device 5. Then, the spray box 1 is closed, and the feeding device 6 is started to supply paint to the spraying device 4. Then, the paint is atomized and sprayed out by the spraying device 4. Subsequently, the motor 3 is started to drive the lead screw 2 to rotate, and the spraying device 4 begins to move, smoothly spraying the atomized paint onto the guardrail. After the guardrail has completed the atomization spraying of paint, the air pump 7 is started to draw the air out of the defogging box 8 at its input end, so that a negative pressure is formed in the defogging box 8. Then, the negative pressure in the defogging box 8 is transmitted through the L-shaped tube 101 in the connecting hole 9 and into the I-shaped tube 102. Multiple suction holes 103 on pipe 102, under the influence of negative pressure, begin to generate suction, which quickly draws the atomized paint that has not yet naturally dissipated in the spray box 1 into the defogging box 8. The atomized paint that enters the defogging box 8 then comes into contact with the inner wall and perforated plate 13 of the defogging box 8, and quickly changes from an atomized state to a liquid state. Finally, the remaining atomized paint is filtered by the filter cotton plate 12 and adsorbed onto the filter cotton plate 12. Finally, the air pump 7 discharges the paint-free gas, at which point the spray box 1 can be opened to replace the guardrail. This prevents the spray box 1 from being opened rashly after spraying, which would cause the atomized paint to drift into the work area and accumulate and cause health problems for users. Therefore, it is necessary to let it stand and wait for it to dissipate naturally, thus having the advantage of quickly eliminating atomized paint.

[0036] In summary, this spraying device for highway corrugated guardrail processing, by setting up an air pump 7 and an anti-fogging box 8, allows the air pump 7 to be activated after the guardrail is painted in the spraying box 1. This pump draws air out of the anti-fogging box 8, creating a negative pressure within the box. This negative pressure is then transmitted through the connecting hole 9, causing the suction mechanism 10 to generate suction, ultimately drawing the atomized paint from the spraying box 1 into the anti-fogging box 8. This solves the problem that because the spraying box is sealed during spraying, a large amount of atomized paint accumulates in the box when spraying the guardrail. This prevents the box from being opened immediately after spraying to avoid the atomized paint drifting into the work area and accumulating and causing health problems for users. However, allowing the atomized paint to settle and dissipate naturally is too time-consuming, significantly reducing production efficiency.
