Description

Technical Field

[0001] This utility model relates to the technical field of foam packaging box processing devices, specifically, to a surface treatment device for mildew-proof and antibacterial foam packaging boxes. Background Technology

[0002] Foam packaging boxes are widely used in the packaging and transportation of food, medicine, electronics and other fields due to their advantages such as light weight, good cushioning performance and low cost. In order to improve their anti-mildew and antibacterial effect, special surface treatment is usually required, such as coating with antibacterial coating or impregnation with antibacterial agent.

[0003] When performing anti-mildew and antibacterial treatment on the surface of foam packaging boxes, corresponding surface treatment equipment is usually used. There are many types of surface treatment equipment for foam packaging boxes on the market, but most of them use spraying. Spraying has the following drawbacks: First, the spraying process is affected by the spraying range and uniformity, easily resulting in uneven coating in some areas of the surface; second, spraying is difficult to cover the entire surface of the box. Even if multiple spray nozzles are used, although comprehensive coverage can be achieved, it can interfere with on-site processing; finally, spraying causes the sprayed slurry to splatter everywhere, easily contaminating surrounding work surfaces and affecting the effectiveness. Therefore, we propose an anti-mildew and antibacterial surface treatment device for foam packaging boxes. Utility Model Content

[0004] The purpose of this invention is to provide a surface treatment device for anti-mildew and antibacterial foam packaging boxes to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A surface treatment device for anti-mildew and antibacterial foam packaging boxes includes an impregnation and coating box. A top frame is provided above the impregnation and coating box. A cylinder is fixedly installed on the top frame. An air distribution plate is detachably installed at the end of the telescopic shaft of the cylinder. Multiple vertical pipes communicating with the interior of the air distribution plate are fixedly installed on the bottom surface of the air distribution plate. Vacuum suction cups are detachably installed at the bottom end of the vertical pipes. A vacuum pump is fixedly installed on the top frame. A rigid pipe is fixedly installed at the suction end of the vacuum pump. The end of the rigid pipe is connected to the air distribution plate through a flexible hose. A vertical plate is fixedly installed on the bottom surface of one side panel of the top frame. An air inlet is fixedly installed on the vertical plate. A hot air blower is fixedly installed on the inner wall of the air inlet.

[0007] Preferably, the lengths of the plurality of vertical pipes increase sequentially from left to right, and the hot air blower is located on the side closest to the shortest vertical pipe;

[0008] This setting enables air drying from left to right, ensuring that each foam packaging box is dried.

[0009] Preferably, a vertically arranged guide post is fixedly installed on the top surface of the air distribution plate, and the guide post passes through the top frame and is slidably connected to the top frame.

[0010] Preferably, a rectangular plate is fixedly installed at the end of the telescopic shaft of the cylinder, and the air distribution plate is detachably installed on the bottom surface of the rectangular plate.

[0011] Preferably, a solenoid valve is fixedly installed on the vertical pipe, and the top frame is fixedly installed on the external frame.

[0012] Preferably, a temperature-controlled electric heater is fixedly installed on the outer side of both the left and right side plates of the impregnation coating box, and a heat-conducting plate is fixedly installed on both the left and right side plates of the impregnation coating box, with the heat-conducting plate located inside the temperature-controlled electric heater.

[0013] This setting allows for heating when needed.

[0014] Preferably, an addition tube is fixedly installed on the side of the top of the impregnation coating box, and the addition tube is used for adding coating slurry.

[0015] Preferably, a circulation pump is provided on one side of the impregnation coating box, a suction pipe is fixedly installed between the liquid inlet end of the circulation pump and the bottom box of the impregnation coating box, and a return pipe is fixedly installed between the liquid outlet end of the circulation pump and the top box of the impregnation coating box.

[0016] This setting allows for the circulation of the internal slurry, preventing sedimentation and other issues.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model uses an immersion coating box to immerse the foam packaging box in the antibacterial slurry inside the box, replacing the traditional spraying method. This achieves full coverage of the box surface and avoids uneven coating and omissions in some areas caused by the limited spraying range, thereby improving the integrity and uniformity of the surface treatment.

[0019] 2. This utility model uses a cylinder to drive a vacuum suction cup to adsorb foam packaging boxes, controlling the immersion time and depth in the immersion coating box. Combined with a circulating pump, the slurry is circulated to avoid sedimentation, achieving precise control of the processing. It eliminates the need for multiple coating nozzles, reducing interference with processing operations, and prevents slurry splashing and contamination of surrounding work surfaces, thus optimizing the processing environment.

[0020] 3. This utility model uses a vacuum pump to provide suction so that the vacuum suction cup can stably adsorb the box, a hot air blower to dry the box after impregnation, and a temperature-controlled electric heater to adjust the temperature of the slurry to ensure the coating effect. It realizes a continuous process from adsorption, impregnation to drying, improves the convenience of operation and processing efficiency, and achieves the effect of ensuring the quality of anti-mildew and antibacterial treatment.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0028] Please see Figures 1-3This utility model provides a technical solution: a surface treatment device for anti-mildew and antibacterial foam packaging boxes, including an impregnation and coating box 1, a top frame 2 above the impregnation and coating box 1, a cylinder 20 fixedly installed on the top frame 2, an air distribution plate 22 detachably installed at the end of the telescopic shaft of the cylinder 20, a plurality of vertical pipes 23 connected to the inside of the air distribution plate 22 fixedly installed on the bottom surface of the air distribution plate 22, a vacuum suction cup 24 detachably installed at the bottom end of the vertical pipes 23, a vacuum pump 25 fixedly installed on the top frame 2, a rigid pipe 251 fixedly installed at the suction end of the vacuum pump 25, and a flexible hose connecting the end of the rigid pipe 251 to the air distribution plate 22. 26 are connected. A vertical plate 27 is fixedly installed on the bottom surface of one side plate of the top frame 2. An air inlet duct 28 is fixedly installed on the vertical plate 27. A hot air blower 281 is fixedly installed on the inner wall of the air inlet duct 28. The suction force generated by the vacuum pump 25 is transmitted to the vacuum suction cup 24 through the rigid pipe 251 and the flexible pipe 26, so that the vacuum suction cup 24 can firmly adsorb the foam packaging box. With the help of the cylinder 20, it drives the box to rise and fall, so as to accurately immerse the packaging box into the slurry of the impregnation and coating box 1. Then, the cylinder 20 drives the coated packaging box to rise to the drying part. The hot air blower 281 blows air through the air inlet duct 28 to dry the impregnated packaging box, ensuring uniform treatment effect.

[0029] In this embodiment, the lengths of multiple vertical pipes 23 increase sequentially from left to right. The hot air blower 281 is located on the side closest to the shortest vertical pipe 23, so that the blowing and drying operation can be carried out from left to right, and the hot air blower 281 can blow on the foam packaging boxes in different positions.

[0030] like Figure 1 As shown, a vertically arranged guide post 29 is fixedly installed on the top surface of the air distribution plate 22. The guide post 29 passes through the top frame 2 and is slidably connected to the top frame 2, so that the air distribution plate 22 can be raised and lowered smoothly, and the packaging box can be prevented from shaking and affecting the processing accuracy.

[0031] like Figure 1 A rectangular plate 21 is fixedly installed at the end of the telescopic shaft of the cylinder 20. The air distribution plate 22 is detachably installed on the bottom surface of the rectangular plate 21 by multiple fastening bolts, which facilitates the replacement and maintenance of the air distribution plate 22.

[0032] Specifically, a solenoid valve 231 is fixedly installed on the vertical pipe 23, and the top frame 2 is fixedly installed on the external frame. The solenoid valve 231 can individually control the suction force of the corresponding vertical pipe 23, flexibly adapting to the processing needs of different numbers of packaging boxes. The top frame 2 is fixed on the external frame to ensure the overall stability of the device.

[0033] Furthermore, temperature-controlled electric heaters 11 are fixedly installed on the outer surfaces of both sides of the impregnation coating box 1, and heat-conducting plates 10 are fixedly installed on both sides of the impregnation coating box 1. The heat-conducting plates 10 are located inside the temperature-controlled electric heaters 11. The slurry in the impregnation coating box 1 is heated by the temperature-controlled electric heaters 11 through the heat-conducting plates 10, so that the slurry maintains a suitable temperature and enhances the activity of antibacterial components.

[0034] like Figure 1 As shown, an addition tube 12 is fixedly installed on the side of the top box of the impregnation coating box 1. The addition tube 12 is used for adding coating slurry. The addition tube 12 facilitates timely replenishment of slurry and avoids affecting the processing efficiency due to insufficient slurry.

[0035] like Figure 1 As shown, a circulation pump 13 is installed on one side of the impregnation coating box 1. A suction pipe 14 is fixedly installed between the liquid inlet end of the circulation pump 13 and the bottom box of the impregnation coating box 1. A return pipe 15 is fixedly installed between the liquid outlet end of the circulation pump 13 and the top box of the impregnation coating box 1. This allows the slurry in the impregnation coating box 1 to circulate, preventing slurry sedimentation and uneven concentration, ensuring that the antibacterial coating thickness on the surface of each foam packaging box is consistent, and improving the processing quality.

[0036] It is worth noting that a drain pipe is installed near the bottom of the rear side of the impregnation and coating box 1, and a valve is installed on the drain pipe so that the valve can be opened to perform a drain operation when necessary.

[0037] Finally, it should be noted that the cylinder 20, vacuum pump 25, hot air blower 281, temperature-controlled electric heater 11, circulating pump 13, corresponding control system, and external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and adapted controllers and power supplies, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0038] When using the surface treatment device for mildew-proof and antibacterial foam packaging boxes of this utility model, first add antibacterial slurry to the impregnation and coating box 1 through the adding pipe 12, start the temperature-controlled electric heater 11 as needed, heat the slurry to a suitable temperature through the heat conduction plate 10, and at the same time turn on the circulation pump 13 to make the slurry circulate through the suction pipe 14 and the return pipe 15.

[0039] Next, place the foam packaging box under the vacuum suction cup 24, open the solenoid valve 231, and the suction force generated by the vacuum pump 25 is transmitted to the vacuum suction cup 24 through the rigid tube 251 and the flexible tube 26 to adhere to the packaging box. Start the cylinder 20, and under the guidance of the guide column 29, the air distribution plate 22 drives the packaging box to descend and accurately immerse it in the slurry of the impregnation coating box 1.

[0040] After impregnation, cylinder 20 lifts the packaging box to the drying area corresponding to hot air blower 281. Hot air blower 281 dries the packaging box by blowing air through air inlet duct 28. After drying, solenoid valve 231 is closed to remove the packaging box, completing the process.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
