Description

Technical Field

[0001] The present application relates to the technical field of spraying devices, and more specifically, to a spraying device with uniform spraying thickness. Background Art

[0002] Barrels are usually used for storing, transporting or packaging items. During the production process of barrels, the outer wall of the barrel needs to be painted to provide anti-corrosion protection and prevent the barrel material from contacting the external environment. Moisture, chemicals or other corrosive factors in the external environment may damage the appearance of the barrel, causing the surface of the barrel to corrode, oxidize or rust. The paint layer can prevent these corrosive factors from eroding the barrel wall, thereby extending the service life of the barrel.

[0003] When spraying existing barrels, the coating liquid has a certain fluidity after spraying. Under the influence of gravity, especially on the vertical barrel wall surface, the coating liquid will flow downward, causing the coating to become thicker in specific areas and thinner in other areas, resulting in uneven spraying thickness. Uneven coating will cause an uneven and bumpy surface, affecting the overall appearance of the barrel. Utility Model Content

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0034] Reference Figure 1-Figure 7 A spraying device with uniform spraying thickness comprises a spraying chamber 1, a fixing frame 8 is rotatably connected inside the spraying chamber 1, a motor 6 is arranged on the top of the spraying chamber 1, a top end of the fixing frame 8 is fixedly connected to an output end of the motor 6, and a spraying assembly is arranged inside the spraying chamber 1;

[0035] There are two groups of spraying components, each group of spraying components includes a slider 16, one end of the slider 16 is provided with a placement frame 18, the inner side of the placement frame 18 is rotatably connected to a rotating roller 17

[0036] Reference Figure 3-Figure 6 Each spraying assembly also includes a sleeve 13, the interior of the sleeve 13 is rotatably connected to a reciprocating screw rod 14, the sleeve 13 is fixedly connected to the inner wall of the spraying chamber 1, the top of the reciprocating screw rod 14 is rotatably connected to the spraying chamber 1, a slider 16 extends through the interior of the sleeve 13 and is threadedly connected to the reciprocating screw rod 14, a second electric push rod 19 is provided between the slider 16 and the placement rack 18, a slide groove is provided on one side of each sleeve 13, the slider 16 is slidably connected to the slide groove, an elastic sealing pad 15 is provided inside the slide groove, and the elastic sealing pad 15 is connected to the slider 16.

[0037] When the motor 6 rotates forward, due to the one-way bearing on the reciprocating screw 14, the reciprocating screw 14 will not rotate, and the motor 6 will drive the barrel alone to rotate and spray paint. When the motor 6 reverses, the reciprocating screw 14 and the barrel rotate synchronously. When the reciprocating screw 14 rotates, it drives the elastic sealing gasket 15 of the slider 16 sleeve 13 to move up and down. The threaded section of the reciprocating screw 14 is the same length as the elastic sealing gasket 15, so the elastic sealing gasket 15 can play a sealing role to prevent the spraying liquid from entering the reciprocating screw 14, driving the rotating roller 17 on the front side of the slider 16 to contact the barrel. When the rotating roller 17 contacts the barrel, the rotating roller 17 rotates, so that the spraying liquid is evenly applied to the surface of the barrel, ensuring consistent coating thickness, improving the quality and appearance of the coating, and avoiding adverse effects caused by uneven coating thickness.

[0038] During the spraying process, the second electric push rod 19 drives the rotating roller 17 to move outward to avoid spraying onto the rotating roller 17 .

[0039] Reference Figure 2-Figure 6 A frame 7 is provided on the top of the spraying room 1, and the frame 7 is located at the bottom of the motor 6. One end of the two sets of reciprocating screw rods 14 extends through the outside of the spraying room 1 and is rotatably connected to the frame 7 through a one-way bearing.

[0040] The one-way bearing can drive the reciprocating screw rod 14 to rotate only when the motor 6 is reversed, and the reciprocating screw rod 14 is not driven to rotate when the motor 6 rotates.

[0041] Reference Figure 4-Figure 5 The two sets of reciprocating screw rods 14 are respectively connected to the motor 6 through a synchronous belt. The four ends of the fixed frame 8 are provided with a first electric push rod 12. The output end of each first electric push rod 12 is fixedly connected to an arc plate 9. The outer walls of the first electric push rod 12 and the second electric push rod 19 are both sleeved with a corrugated sleeve 10.

[0042] The first electric push rod 12 and the arc plate 9 fix and clamp the upper end of the barrel to prevent the barrel from falling during rotation and spraying;

[0043] The provision of the corrugated sleeve 10 can prevent the spraying liquid from entering the interior of the first electric push rod 12 and the second electric push rod 19, and because it can be extended and retracted, the normal operation of the first electric push rod 12 and the second electric push rod 19 is ensured.

[0044] Reference Figure 1-Figure 2 A connecting frame 2 is fixedly connected to one side of the spraying room 1, a moving block 4 is fixedly connected to the inner side of the connecting frame 2, an electric slide rail 3 is slidably connected to the moving block 4, a spray gun 5 is provided on the front side of the electric slide rail 3, a leak plate 11 is provided inside the spraying room 1, and a taking door is opened on the side of the spraying room 1 away from the connecting frame 2.

[0045] When the barrel-shaped object is sprayed, the spray gun 5 on the front side of the moving block 4 is driven by the electric slide rail 3 to move up and down to spray the barrel-shaped object, and the dripping spray liquid leaks from the leak plate 11.

[0046] Working principle: When in use, first fix and clamp the upper end of the barrel by the first electric push rod 12 and the arc plate 9, and then the electric slide rail 3 drives the spray gun 5 on the front side of the moving block 4 to move up and down to spray the barrel. At this time, the motor 6 rotates forward to drive the barrel to rotate and spray paint, so that the paint can be sprayed on every surface of the barrel. After the spraying is completed, the motor 6 reverses, and the reciprocating screw 14 and the barrel rotate synchronously. When the reciprocating screw 14 rotates, it drives the elastic sealing pad 15 of the slider 16 sleeve 13 to move up and down, so that the rotating roller 17 contacts with the barrel. When they contact, the rotating roller 17 rotates to evenly apply the spray liquid on the surface of the barrel, ensuring consistent coating thickness, improving the quality and appearance of the coating, and avoiding adverse effects caused by uneven coating thickness.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
