Description

Technical Field

[0001] This utility model relates to the field of spraying equipment for the inner wall of metal cans, and more particularly to a spraying device. Background Technology

[0002] Tinplate, manufactured through processes such as rounding, welding, and rolling, serves as a widely used packaging container in the industrial sector. It is primarily used for storing liquids, powders, and hazardous chemicals, such as building coatings, waterproofing materials, and natural waxes. Depending on the contents, an internal coating is chosen to enhance the product's corrosion resistance, sealing, and overall durability and lifespan. Traditional processes involve pre-coating the inner wall of the tinplate using lamination or offset printing. While offset printing and surface lamination machines offer high production capacity suitable for mass production of standard products, frequent changes in specifications and quantities lead to low production efficiency and increased defect rates when dealing with diverse specifications and small quantities.

[0003] Currently, the internal coating of rolled iron drums involves pre-coating followed by roll-up and then spraying the weld seams evenly using a spray nozzle. However, current spray nozzles can only touch up the weld seams and cannot cover large areas inside the drum. Using robotic arms for spraying results in high costs due to limited working space. Therefore, this application proposes a spraying device. Utility Model Content

[0004] The purpose of this invention is to provide a spraying device to solve the problems of flexible switching of diverse coatings on the inner wall of rolled iron drums and the high cost of current spraying devices.

[0021] Furthermore, the lifting rod is rotatably connected to the slide block, the lifting rod is arranged parallel to the guide rail, and the rotating part includes:

[0045] Example 1

[0046] like Figures 1 to 3 As shown in the figure, an embodiment of the present invention provides a spraying device, which includes a frame 10, a slide 20, a lifting rod 30, a nozzle 40, and a lifting assembly 50. The frame 10 is provided with a guide rail 11, the slide 20 is slidably connected to the guide rail 11, the lifting assembly 50 is fixedly connected to the frame 10, the output end of the lifting assembly 50 is connected to the slide 20 to drive the slide 20 to slide on the guide rail 11, one end of the lifting rod 30 is fixedly connected to the slide 20, and the nozzle 40 is fixedly connected to the end of the lifting rod 30 away from the slide 20.

[0047] In this embodiment, during in-drum spraying, the nozzle 40 is connected to a spraying machine. The spraying material input by the spraying machine is atomized at the nozzle 40 and sprayed into the rolled iron drum. During the spraying process, the lifting assembly 50 controls the slide 20 to slide on the frame 10. As the slide 20 slides on the guide rail 11, the slide 20 drives the nozzle 40 to slide in a straight line through the lifting rod 30, so that the nozzle 40 moves inside the rolled iron drum, thereby making the atomized coating sprayed by the nozzle 40 evenly sprayed into the rolled iron drum, thus completing the spraying work.

[0048] The spraying device disclosed in this embodiment of the utility model uses a lifting assembly 50 located on the frame 10 to drive the slide 20 to slide linearly on the guide rail 11. During the sliding process, the slide 20 drives the spray head 40 to move inside the barrel through the lifting rod 30, so that the paint is evenly sprayed inside the rolled iron barrel. Compared with the traditional structure, the present utility model has a simple structure and low cost.

[0049] Specifically, in this embodiment, the frame 10 is a support structure made of profiles, the guide rail 11 is fixedly connected to the frame 10 by bolts, the slide block 20 is provided with a slider 21, the guide rail 11 is an I-shaped track, the slider 21 is provided with a groove that mates with the guide rail 11, the slider 21 is fixedly connected to the slide block 20 by bolts, the slide block 20 is a steel plate structure, the lifting rod 30 is fixedly connected to the slide block 20 by bolts, the lifting rod 30 is a square tube or square steel, and the nozzle 40 is fixed with a spray bar 41, the spray bar 41 is fixedly connected to the end of the lifting rod 30 away from the slide block 20 by threads or screws.

[0050] In a preferred embodiment of this invention, the lifting assembly 50 includes a synchronous belt 51, a synchronous pulley 52, and a lifting motor 53. The lifting motor 53 is fixedly connected to one end of the frame 10. The synchronous pulley 52 is rotatably connected to the frame 10 via a bearing or bushing structure. The synchronous belt 51 is sleeved on the synchronous pulley 52. ​​The output shaft of the lifting motor 53 is fixedly connected to the synchronous pulley 52. ​​When the lifting motor 53 is energized, it drives the synchronous pulley 52 to rotate, thereby driving the synchronous belt 51 to rotate. A drive plate 22 and a clamping plate 23 are also fixedly connected to the slide block 20. The drive plate 22 and the clamping plate 23 are connected by bolts and clamped on the synchronous belt 51. One section of the synchronous belt 51 is located between the drive plate 22 and the clamping plate 23, so that when the synchronous belt 51 rotates, it drives the drive plate 22 to move.

[0051] It should be noted that in this embodiment, the lifting component 50 can also be other structures. For example, in some other embodiments, the lifting component 50 is a lead screw moving structure, and the lead screw nut on the lifting component 50 is fixedly connected to the slide block 20 by bolts, so that the lifting component 50 can drive the slide block 20 to move in a straight line.

[0052] In a preferred embodiment of this invention, a mounting plate 12 is also fixed to the frame 10 by bolts. The mounting plate 12 is L-shaped and is used to connect to the production line.

[0053] In a preferred embodiment of this invention, the spraying device further includes:

[0054] The position detection unit 60 is used to detect the position of the slide 20 to prevent the nozzle 40 from hitting the rolled iron drum.

[0055] Preferably, in this embodiment, the position detection unit 60 includes a fixed bracket 61 and a proximity sensor 62. The fixed bracket 61 is a plate-shaped structure and is fixedly connected to the frame 10. The proximity sensor 62 is fixedly connected to the fixed bracket 61 by a nut. Multiple proximity sensors 62 are provided, and the multiple proximity sensors 62 are respectively arranged at the positions to be detected. When the slide 20 moves, the clamping plate 23 passes through the proximity sensor 62 and causes the proximity sensor 62 to generate a current change. In this embodiment, the clamping plate 23 is an iron plate, and the proximity sensor 62 is a sensor based on the Hall effect principle.

[0056] In this embodiment, the proximity sensor 62 can also be a light intensity sensor. When the clamping plate 23 passes the proximity sensor 62, the light from the proximity sensor 62 is blocked, thereby generating a change in current.

[0057] Example 2

[0058] In one embodiment of this utility model, such as Figures 4 to 6 As shown, the difference between this embodiment and Embodiment 1 is that the lifting rod 30 is rotatably connected to the slide block 20, and the spraying device further includes:

[0059] The rotating part 70 is used to drive the lifting rod 30 to rotate;

[0062] Preferably, a height adjustment component 80 is also fixed on the mounting plate 12. The height adjustment component 80 is used to adjust the height of the frame 10. In this embodiment, since the lifting rod 30 can rotate, the nozzle 40 can be adapted to a variety of different nozzle structures, such as a fan-shaped atomizing nozzle or a ring-shaped atomizing nozzle.

[0063] Since the trajectory of the nozzle 40 is spiral when the lifting rod 30 rotates, in order to improve the uniformity of spraying, after the nozzle 40 moves to one end, the height adjustment component 80 controls the height change of the frame 10, so that the trajectory of the nozzle 40 becomes a double spiral trajectory, which can control the spray to be more uniform.
