Description

Technical Field

[0001] This utility model relates to the technical field of tinplate processing equipment, and in particular to a tinplate surface coating device. Background Technology

[0002] During the processing of tinplate, a coating is required on its surface. A specialized coating machine evenly applies the coating to the tinplate surface. The coating used for tinplate coating is relatively viscous. Therefore, conventional coating machines that rely on gravity to allow the coating to flow onto the coating brush are prone to clogging during the coating process, preventing the coating from being fully applied to the conveyor rollers and ultimately resulting in poor coating quality.

[0003] Chinese Patent CN210304328U discloses a tinplate surface coating device. In this device, paint from a material tank enters a hollow drum through a material pipe. The rotating hollow drum creates a centrifugal force, causing the paint to continuously exit through several discharge holes and coat a paint brush. Because the hollow drum is movably connected to the material pipe, its rotation does not cause the pipe to rotate. The paint continuously tumbles within the hollow drum, achieving rotary discharge, which changes the traditional method of discharge relying solely on gravity. Even paints with a certain viscosity can be discharged smoothly, thus ensuring the coating quality of the tinplate. However, while solving the problem, this tinplate surface coating device has the following drawbacks:

[0004] Due to centrifugal force, as the paint brush rotates with the hollow roller, the paint on its surface will splash everywhere. Even if the hollow roller is covered by a protective cover, a large amount of paint will still splash onto the inner wall of the protective cover and then flow down along the gap between the protective cover and the hollow roller. This not only affects the hygiene around the coating device but also wastes paint. Furthermore, the paint may spill onto the tinplate below, which may still affect the coating quality. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0006] Therefore, one objective of this utility model is to provide a tinplate surface coating device, which aims to solve the problems of existing tinplate surface coating devices affecting the hygiene around the coating device, wasting coating material, and still potentially affecting the coating quality.

[0007] To achieve the above objectives, one embodiment of this utility model provides a tinplate surface coating device, including a base, characterized in that a mounting frame is fixedly connected to the top of the base, a hollow cylinder is fixedly connected inside the mounting frame, a feed pipe is provided on one side of the hollow cylinder, a plurality of discharge holes are opened at the bottom of the outer surface of the hollow cylinder, brush bristles are fixedly connected inside the discharge holes, a sealed bearing is fixedly installed at the center of both ends of the hollow cylinder, the hollow cylinder is rotatably connected to a rotating shaft through the sealed bearing, and a plurality of centrifugal plates are fixedly connected to the outer surface of the rotating shaft.

[0008] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0009] The brush bristles remain stationary, preventing paint from splattering and ensuring cleanliness around the coating unit. This also saves paint and guarantees coating quality.

[0010] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0018] This invention provides a coating device for tinplate surfaces.

[0019] Example 1:

[0020] like Figure 1-3 As shown, it includes a base 1, characterized in that a mounting frame 11 is fixedly connected to the top of the base 1, a hollow cylinder 3 is fixedly connected inside the mounting frame 11, a support rod 12 is fixedly connected to the top of the inner side of the mounting frame 11, the bottom end of the support rod 12 is fixedly connected to the hollow cylinder 3, a feed pipe 31 is provided on one side of the hollow cylinder 3, the paint enters the interior of the hollow cylinder 3 through the feed pipe 31, a plurality of discharge holes 32 are opened at the bottom of the outer surface of the hollow cylinder 3, bristles 321 are fixedly connected inside the discharge holes 32, the paint seeps out through the gaps between the bristles 321 and between the bristles and the discharge holes 32, and the center of both ends of the hollow cylinder 3 A sealed bearing 33 is fixedly installed at the hollow cylinder 3. The hollow cylinder 3 is rotatably connected to the rotating shaft 34 through the sealed bearing 33. A motor is fixedly installed on the mounting frame 11. The output end of the motor is rotatably connected to the rotating shaft 34 and can be used to drive the rotating shaft 34 to rotate. Multiple centrifugal plates 35 are fixedly connected to the outer surface of the rotating shaft 34. The rotating shaft 34 drives the centrifugal plates 35 to rotate, causing the centrifugal plates 35 to tumble the paint in the hollow cylinder 3. The centrifugal force causes the paint to move towards the inner wall of the hollow cylinder 3. Thus, when the paint passes through the discharge hole 32, the paint will quickly seep out from the gap between the bristles 321 and the gap between the brush and the discharge hole 32.

[0021] Specifically, a support plate 7 is fixedly connected to the top of the mounting frame 11, a material box 71 is fixedly installed on the top of the support plate 7, a discharge pipe 72 is fixedly connected to the bottom of one side of the material box 71, a valve is provided on the discharge pipe 72 to control the discharge rate, and the end of the discharge pipe 72 away from the material box 7 is fixedly connected to the feed pipe 31. The paint in the material box 71 can be transported to the interior of the hollow cylinder 3 through the discharge pipe 72.

[0022] Specifically, inside the mounting frame 11, an anilox roller 2, a rubber roller 4, and a conveyor roller 5 are rotatably connected from top to bottom. The anilox roller is located below the hollow cylinder 3, and its top is in contact with the bristles 321.

[0023] Specifically, positioning shafts 6 are fixedly connected to both ends of the anilox roller 2, rubber roller 4, and conveyor roller 5. The anilox roller 2, rubber roller 4, and conveyor roller 5 are rotatably connected to the mounting frame 11 through the positioning shafts 6 at both ends. Bearings are provided on both sides of the mounting frame 11. The positioning shafts 6 are rotatably connected to the mounting frame 11 through the bearings. Multiple motors are installed on one side of the mounting frame 11. The output ends of the multiple motors are respectively connected to the positioning shafts 6 at one end of the anilox roller 2, rubber roller 4, and conveyor roller 5 to achieve the purpose of driving the anilox roller 2, rubber roller 4, and conveyor roller 5 to rotate.

[0024] The working principle of this utility model is as follows: In use, multiple motors drive the rotating shaft 34, the anilox roller 2, the rubber roller 4, and the conveying roller 5 to rotate respectively. The paint in the material box 71 enters the hollow cylinder 3 through the discharge pipe 72. The rotating centrifugal plate 35 drives the paint to move, and the paint generates centrifugal force. When the paint passes through the discharge hole 32, it will seep out through the gap between the bristles 321 and the gap between the brush and the discharge hole 32, and then flow along the bristles 321 to the surface of the anilox roller 2. The rotating anilox roller 2 then coats the paint onto the surface of the rubber roller 4. Tinplate is placed between the rubber roller 4 and the conveying roller 5. The conveying roller 5 conveys the tinplate, and the rubber roller 4 coats the paint onto the tinplate.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] The rotating shaft 34 drives the centrifugal plate 35 to rotate, and the centrifugal plate 35 drives the paint in the hollow cylinder 3 to move. After the paint generates centrifugal force, it seeps out from the gap between the bristles 321 and the discharge hole 32. Since the bristles 321 are stationary, the paint will not splash everywhere, ensuring the hygiene around the coating device, while saving paint and ensuring the quality of coating.
