Description

Technical Field

[0001] This utility model relates to the field of rust prevention technology for metal products, specifically to a rust prevention spraying device for packaging boxes. Background Technology

[0002] In everyday environments, metal products are prone to rust and corrosion, so certain methods are needed to prevent rust. Covering the metal surface with a protective layer can isolate the metal products from the surrounding corrosive media, thereby preventing corrosion.

[0003] Chinese Patent No. CN223010936U discloses a packaging box pattern spraying device, specifically relating to the technical field of pattern spraying devices. It includes two mounting components, each with a support component at its top. The front end of each support component has a spraying assembly for spraying patterns onto the packaging box surface; the rear end of each support component has a drying assembly for drying the coating on the packaging box. This invention uses a motor to drive two support shafts, which are driven by a belt and two pulleys. These support shafts then drive corresponding fans. The fans, with their hollow tubes, discharge air heated by heating wires through vents to the packaging box. This allows for simultaneous drying of the packaging box with both hot and cold air. The simultaneous use of hot and cold air maintains a relatively stable and moderate temperature environment while ensuring drying efficiency, effectively preserving the integrity of the pigment and the authenticity of the color.

[0004] However, in the above technical solution, the rotation of the two support shafts driven by only the belt and two pulleys can allow hot air and cold air to dry the packaging box simultaneously. However, when spraying anti-rust coating on the packaging box, some packaging boxes also need to have their inner walls sprayed to meet the requirements of comprehensive anti-rust. While meeting the requirements of spraying the inside of the packaging box, it is also necessary to consider the adaptability to packaging boxes of different specifications and shapes. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a rust-proof spraying device for packaging boxes.

[0006] The technical solution of this utility model is as follows: A rust-proof spraying device for packaging boxes includes a spraying equipment body, which includes a frame, a belt conveyor, and a support frame.

A spraying unit is connected to the support frame. The spraying unit includes a telescopic device, a fixing component, and a spraying component. The telescopic device is connected to the support frame, and the telescopic end of the telescopic device is connected to the fixing component and the spraying component. The fixing component includes a limiting component and a rotating component. The rotating component is connected to the telescopic device, and the limiting component is connected to the rotating component. The rotating component includes a fixed plate, a rotating plate, a transmission component, and a drive device. The fixed plate is connected to the telescopic end of the telescopic device, the rotating plate is rotatably connected to the fixed plate, the drive device is connected to the fixed plate, and the output rod of the drive device passes through the fixed plate and is positioned between the fixed plate and the rotating plate. The transmission component is positioned between the fixed plate and the rotating plate and is connected to the output rod to drive the rotating plate and the limiting component to rotate. The spraying assembly includes an inner nozzle, an outer nozzle, and support rods. The two support rods are arranged in parallel, and the inner nozzle and the outer nozzle are arranged on opposite sides of the support rods. Multiple inner nozzles and outer nozzles are arranged in an array along the length of the support rods.

[0007] Preferably, the limiting component includes a connecting frame, one end of which is connected to the rotating plate, and a mounting ring is connected to one end of the connecting frame; multiple mounting plates are distributed in an array on the mounting ring with the central axis of the connecting frame as the center, and each mounting plate is connected to an electromagnet, which magnetically attracts the packaging box.

[0008] Preferably, the connecting frame consists of a fixed sleeve and a movable sleeve. The fixed sleeve is connected to the rotating plate, and the fixed sleeve and the movable sleeve are nested together. The movable sleeve and the fixed sleeve are detachably connected.

[0009] Preferably, the transmission component consists of a driving gear and a driven gear ring. The driving gear is connected to the output rod, and the driven gear ring is connected to the rotating plate. The driven gear ring meshes with the driving gear for transmission.

[0012] Preferably, both the inner and outer nozzles are angled.

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0014] In this invention, by setting up inner and outer spray nozzles, both the inner and outer walls of the packaging box can be sprayed simultaneously. The inner spray nozzle is responsible for rust prevention of the inner wall of the packaging box, while the outer spray nozzle is responsible for rust prevention of the outer wall, achieving all-round rust prevention coverage of the packaging box. This effectively prevents various parts of the metal packaging box from rusting due to contact with corrosive media. Compared with the traditional method of spraying only the outer wall, this greatly improves the rust prevention effect and the service life of the packaging box. By adjusting the relative position of the movable sleeve and the fixed sleeve, the overall length of the connecting frame can be changed, thereby adapting to packaging boxes of different diameters and ensuring that the electromagnet can stably attract packaging boxes of different specifications, achieving reliable fixation.

[0020] Example 1, as Figures 1-4As shown, this utility model proposes a rust-proof spraying device for packaging boxes, comprising a spraying equipment body and a spraying unit. The spraying equipment body includes a frame 1, a belt conveyor 2, and a support frame 3. The belt conveyor 2 is connected to the frame 1, and the support frame 3 is positioned above the belt conveyor 2 and connected to the frame 1. An infrared sensor 5 is connected to the frame 1. The infrared sensor 5 is a conventional through-beam sensor, which consists of a transmitter and a receiver. After being connected to an external controller or PLC, it can control the operation of the telescopic device 4, the drive device 11, and the electromagnet 17. The spraying unit is connected to the support frame 3 and includes a telescopic device 4, a fixing component, and a spraying component. The telescopic device 4 is connected to the support frame 3. The telescopic device 4 is, but is not limited to, a hydraulic cylinder, which is connected to an external hydraulic device with preset values. The telescopic end of the telescopic device 4 is connected to the fixing component and the spraying component. The fixing component includes a limit switch. The assembly includes a fixed plate 8, a rotating plate 9, a transmission component 10, and a driving device 11. The fixed plate 8 is connected to the telescopic end of the telescopic device 4, the rotating plate 9 is rotatably connected to the fixed plate 8, and the driving device 11 is connected to the fixed plate 8. The driving device 11 is selected from, but is not limited to, a geared motor, which has its own reducer to maintain a stable rotation speed. The output rod of the driving device 11 passes through the fixed plate 8 and is located between the fixed plate 8 and the rotating plate 9. The transmission component 10 is located between the fixed plate 8 and the rotating plate 9 and is connected to the output rod to drive the rotating plate 9 and the limiting component 6 to rotate. The spraying assembly includes an inner nozzle 12, an outer nozzle 13, and a support rod 14. The two support rods 14 are arranged in parallel. The inner nozzle 12 and the outer nozzle 13 are arranged on opposite sides of the support rods 14. Multiple inner nozzles 12 and outer nozzles 13 are arranged in an array along the length of the support rods 14.

[0021] Example 2, as Figures 2-3 As shown, this utility model proposes a rust-proof spraying device for packaging boxes. Compared with Embodiment 1, this embodiment describes the detailed structure of the fixing component.

[0022] The limiting component 6 includes a connecting frame 15, a mounting ring, a mounting plate 16, and an electromagnet 17. One end of the connecting frame 15 is connected to the rotating plate 9, and the other end of the connecting frame 15 is connected to the mounting ring.

[0023] The connecting frame 15 consists of a fixed sleeve 18 and a movable sleeve 19. The fixed sleeve 18 is connected to the rotating plate 9. The fixed sleeve 18 and the movable sleeve 19 are nested together. The movable sleeve 19 and the fixed sleeve 18 are detachably connected by bolts. The arrangement of the movable sleeve 19 and the fixed sleeve 18 allows the position of the electromagnet 17 relative to the fixed plate 8 to be adjusted. The distance between the electromagnet 17 and the support rod 14 can be changed to adapt to packaging boxes of different depths.

[0024] Multiple mounting plates 16 are distributed in an array on the mounting ring with the central axis of the connecting frame 15 as the center. Each mounting plate 16 is connected to an electromagnet 17, which magnetically attracts the packaging box. The electromagnet 17 uses magnetic force to attract the metal packaging box containing iron. This gripping method can reduce the contact area with the packaging box and prevent it from affecting the spraying effect.

[0025] The transmission component 10 consists of a driving gear 20 and a driven gear ring 21. The driving gear 20 is connected to the output rod, and the driven gear ring 21 is connected to the rotating plate 9. The driven gear ring 21 meshes with the driving gear 20 for transmission.

[0026] Example 3, as Figure 2 , Figure 4 As shown, this utility model proposes a rust-proof spraying device for packaging boxes. Compared with Embodiment 2, this embodiment describes the detailed structure of the spraying components.

[0027] The spraying assembly also includes a connecting rod 22, which is connected to the fixed plate 8 and to the support frame 3 for mounting the outer spray head 13. The length of the connecting rod 22 determines the distance between the inner spray head 12 and the outer spray head 13, making it compatible with various types of packaging boxes.

[0028] The connecting rod 22 consists of a fixed rod body 23 and a movable rod body 24. The fixed rod body 23 is connected to the fixed plate 8. A cavity is opened in the fixed rod body 23 to accommodate the movable rod body 24. The movable rod body 24 is detachably connected to the fixed rod body 23 by bolts. The fixed rod body 23 and the movable rod body 24 can adapt to packaging boxes of different sizes by extending and retracting their lengths.

[0029] Both the inner nozzle 12 and the outer nozzle 13 are inclined. Inclined settings of the inner nozzle 12 and the outer nozzle 13 are better than horizontal settings, as they can improve the uniformity of spraying, reduce paint waste, improve the spraying effect, and adapt to packaging boxes of different shapes.

[0030] In summary, when using this utility model, the metal packaging box to be coated with anti-rust paint is placed on the belt conveyor 2. The belt conveyor 2 transports the packaging box forward along the conveying direction at a stable speed. When the packaging box moves into the detection range of the infrared sensor 5, the infrared light emitted by the emitting end of the infrared sensor 5 is blocked by the packaging box, and the receiving end cannot receive the infrared signal. A detection signal is then generated and transmitted to the control system or controller of the device. After receiving the signal, the control system or controller controls the telescopic device 4 to start working. The telescopic end of the telescopic device 4 extends, driving the fixing component and the spraying component to move downwards as a whole. At the same time, the control system will adjust the spraying according to preset parameters and... The actual position of the packaging box is precisely adjusted by controlling the telescopic length and direction of the telescopic device 4 to ensure that the fixing component and the spraying component are accurately positioned above the packaging box. When the telescopic device 4 moves the fixing component and the spraying component down a certain distance, the mounting ring at one end of the connecting bracket 15 in the limiting component 6, along with its mounting plate 16 and electromagnet 17, approaches the top of the packaging box. At this time, the control system controls the electromagnet 17 to be energized, and the electromagnet 17 generates magnetic force to firmly attract the top of the packaging box. Then, the control system starts the drive device 11, and the output rod of the drive device 11 begins to rotate. The output rod drives the drive gear 20 to rotate and mesh with the driven gear ring 21 for transmission. The gear ring 21 also rotates, causing the rotating plate 9 to rotate relative to the fixed plate 8. The rotation of the rotating plate 9 is transmitted to the limiting member 6 through the connecting frame 15, which in turn causes the packaging box attracted by the electromagnet 17 to rotate. At the same time as the packaging box starts to rotate, the inner nozzle 12 and the outer nozzle 13 in the spraying assembly start to work. The inner nozzle 12 is responsible for spraying the inner wall of the packaging box, and the outer nozzle 13 is responsible for spraying the outer wall of the packaging box. During the spraying process, the packaging box continues to rotate, and the inner nozzle 12 and the outer nozzle 13 continuously spray paint. Through the rotation of the packaging box and the coordinated work of the nozzles, the paint is evenly covered on the inner and outer surfaces of the packaging box, forming a uniform and dense coating. The anti-rust coating is applied by controlling the inner spray nozzle 12 and the outer spray nozzle 13 to stop spraying paint after the packaging box rotates one revolution, thus completing the anti-rust spraying work on the packaging box. Then, the control system controls the electromagnet 17 to be de-energized, the magnetic force of the electromagnet 17 disappears, and the packaging box is no longer attracted and fixed. Then, the control system controls the telescopic end of the telescopic device 4 to retract, driving the fixing component and the spraying component to move upward as a whole, returning to the initial position, preparing for the spraying of the next packaging box. At the same time, the belt conveyor 2 continues to run, transporting the packaging box with the anti-rust coating sprayed out of the spraying area and into the next process. This cycle is repeated to achieve continuous anti-rust spraying of metal packaging boxes.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
