Due to its high strength, corrosion resistance (after surface treatment), and durability, it is widely used for the storage and transportation of liquids or solids in industries such as industry, agriculture, chemicals, and food. The surface coating of a steel drum mainly involves uniformly applying paint (such as anti-corrosion paint, topcoat, and anti-rust paint) to the outer or inner wall of the drum to form a continuous and dense protective film or decorative layer.
[0003] The coating process for steel drums is mostly done manually, which takes a long time and is labor-intensive. Furthermore, the pressure and speed of manual coating are difficult to control, which can lead to deviations in coating thickness. Utility Model Content

[0018] 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.
[0019] Please see Figure 1-5 This utility model provides a technical solution: a roller coating device for the body of a steel drum, including a base plate 1, a roller coating assembly 4 and a drive assembly 5 disposed on the base plate 1, the roller coating assembly 4 including a base 41, a first motor 42 and a second electric cylinder 43 mounted on the base 41, the push rod of the second electric cylinder 43 is fixedly connected to a pressure sensor 410, the pressure sensor 410 is fixedly connected to a second connecting block 45, the output shaft of the first motor 42 is fixedly connected to a first connecting block 44, a first roller coating roller 46 is mounted on the first connecting block 44, a second roller coating roller 47 is mounted on the second connecting block 45, and the drive assembly 5 is used to drive the steel drum to rotate.
[0020] The first coating roller 46 is driven by the first motor 42, and the second coating roller 47 is driven by the second electric cylinder 43. When the first motor 42 is working, it can drive the first coating roller 46 to rotate. When placing the steel drum, it can avoid it by rotating. After the steel drum is placed and positioned, it can be rotated back to the inner wall of the steel drum. When the second electric cylinder 43 is working, it can drive the second connecting block 45 to slide along the slide groove 411 to adjust the distance between the first coating roller 46 and the second coating roller 47. This distance is adapted to the wall thickness of the steel drum, so that the brush layer 48 of the first coating roller 46 is in close contact with the inner wall of the steel drum, and the brush layer 48 of the second coating roller 47 is in close contact with the outer wall of the steel drum. When the steel drum is rotated under the drive of the drive component 5, the paint on the brush layer 48 can be evenly coated on the outer and inner walls of the drum, forming a continuous and dense protective film or decorative layer. It can simultaneously coat the inner and outer walls of the drum, replacing manual coating, improving coating efficiency and reducing labor intensity.
[0021] The pressure sensor 410 feeds back pressure data, and the contact pressure between the first coating roller 46 and the second coating roller 47 and the barrel body is controlled accordingly. The pressure is controlled before coating to keep it in the optimal range, avoiding excessive pressure that causes paint to be squeezed and dripped, and avoiding insufficient pressure that causes paint to be transferred, thereby achieving uniform coating.
[0022] The base plate 1 is equipped with a first electric cylinder 2. The push rod of the first electric cylinder 2 is fixedly connected to the drive arm 3. The drive arm 3 is fixedly connected to the roller coating assembly 4. When the first electric cylinder 2 is working, it drives the drive arm 3 at one end, and drives the roller coating assembly 4 through the drive arm 3 to adjust the height position of the first roller coating roller 46 and the second roller coating roller 47, so as to ensure that the first roller coating roller 46 and the second roller coating roller 47 can cover the barrel body.
[0023] The first roller coating roller 46 and the second roller coating roller 47 each have multiple sets of material holes 461. The coating material inside the first roller coating roller 46 and the second roller coating roller 47 flows out through the multiple sets of material holes 461 and is absorbed by the brush layer 48.
[0024] The first roller coating roller 46 and the second roller coating roller 47 are both equipped with a roller brush layer 48, and the roller brush layer 48 is connected to the first roller coating roller 46 and the second roller coating roller 47 through bearings. The roller brush layer 48 is made of fiber, has a certain elasticity and can absorb paint. During roller coating, under the action of friction, the roller brush layer 48 can roll relative to the roller coating roller, thereby uniformly coating the paint on the barrel.
[0025] One end of the first roller coating roller 46 and the second roller coating roller 47 is connected to a feeding hose 49, which is connected to a feeding pump. The feeding pump works to transport the coating material. The coating material enters the first roller coating roller 46 and the second roller coating roller 47 through the feeding hose 49, and then flows out through multiple sets of material holes 461 and is absorbed by the brush layer 48.
[0026] The base 41 has a sliding groove 411, and the second connecting block 45 is slidably connected to the sliding groove 411. When the second electric cylinder 43 is working, it can drive the second connecting block 45 to slide along the sliding groove 411.
[0027] The drive assembly 5 includes two sets of mounting brackets, on which a second motor 51 and an electromagnet 52 are respectively mounted. The magnetic field generated by the electromagnet 52 after it is energized is used to attract and fix the ferromagnetic steel barrel.
[0028] The output shaft of the second motor 51 is fixedly connected to the drive gear 53, and the electromagnet 52 is fixedly provided with a driven gear 54. The drive gear 53 and the driven gear 54 mesh and transmit power.
[0029] When the second motor 51 is working, it drives the active gear 53 at one end to rotate. Through the meshing transmission between the teeth, it drives the driven gear 54 to rotate. The driven gear 54 drives the electromagnet 52 to rotate. The electromagnet 52 drives the steel barrel to rotate. During the rotation of the steel barrel, the roller brush layer 48 evenly roller brushes the inner and outer walls of the steel barrel to achieve roller coating.
[0030] The electromagnet 52 is powered by an electric slip ring, which is mainly composed of a stator and a rotor, which are coaxially mounted. When the rotor rotates with the electromagnet 52, the brushes of the stator and the contacts of the rotor maintain sliding contact, and the current is transmitted from the stator to the rotor through the contact points to provide power.
[0031] Working principle: In use, the first coating roller 46 rotates under the drive of the first motor 42 to avoid obstructing the steel drum to be coated, placing it on the electromagnet 52. Then, the first coating roller 46 rotates and resets under the drive of the first motor 42, moving to the inner wall of the steel drum. The height of the coating assembly 4 is adjusted by the first electric cylinder 2 to ensure that the first coating roller 46 and the second coating roller 47 can cover the drum body. The second electric cylinder 43 drives the second connecting block 45 to slide along the slide groove 411, adjusting the distance between the first coating roller 46 and the second coating roller 47. This distance is adapted to the wall thickness of the steel drum. Pressure data is fed back by the pressure sensor 410, which controls the first coating roller 46 accordingly. The contact pressure between the first and second coating rollers 46 and the barrel body causes the brush layer 48 of the first coating roller 46 to adhere tightly to the inner wall of the steel barrel, and the brush layer 48 of the second coating roller 47 to adhere tightly to the outer wall of the steel barrel. The magnetic field generated by the electromagnet 52 after being energized attracts and fixes the ferromagnetic steel barrel. The drive assembly 5 drives the steel barrel to rotate for coating. Under the action of friction, the brush layer 48 rolls relative to the coating roller, thereby uniformly coating the coating on the barrel body. The feed pump works to transport the coating material. The coating material enters the first coating roller 46 and the second coating roller 47 through the feed hose 49, and then flows out through multiple sets of material holes 461. It is absorbed by the brush layer 48 and transferred to the barrel body during coating.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
