Description

Technical Field

[0001] This utility model relates to the field of idler roller production technology, specifically to an idler roller surface coating device. Background Technology

[0002] Belt conveyors are widely used as transportation equipment in various environments, such as mines, ports, and power plants. Idler rollers, as a crucial component of belt conveyors, significantly impact the stable operation of the conveyor. During use, idler rollers may come into contact with moisture, dust, acids, alkalis, and other corrosive substances. Furthermore, the surface of the idler rollers rubs against materials and the conveyor belt, affecting the service life of both the rollers and the belt. Therefore, painting is commonly used in idler roller production to address these issues. Painting the roller surface creates a protective film, isolating it from air, moisture, and corrosive media, preventing rust and corrosion of the metal surface during transportation and storage.

[0003] The existing method of painting idler rollers mainly relies on manual operation of the paint sprayer. Since the outer surface of the roller is cylindrical, in order to ensure that the surface of the roller is evenly covered with paint, the workers need to slowly rotate the idler roller so that different parts face the paint gun in turn, and also move the sprayer left and right to cover the entire length of the idler roller. This operation method is not only inefficient, but also consumes a lot of time and manpower, and the utilization rate of paint is quite low.

[0004] Based on the above problems, a coating device for the surface of idler rollers is proposed. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a coating device for the surface of idler rollers, which can replace traditional manual coating, reduce labor intensity, and improve the coating quality and coating effect of idler rollers.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A coating device for the surface of an idler roller includes a support frame, a material tray on the support frame, a drive roller above the material tray, and a first support roller and a second support roller above the drive roller. The outer edge of the first support roller contacts the outer edge of the drive roller. The first support roller and the second support roller are used to support the idler roller. A drive unit is provided on one side of the support frame, and the drive unit provides power to the drive roller, the first support roller, and the second support roller.

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

[0009] This invention utilizes a method where paint from a material tray is applied to a support roller by contacting the active roller with the support roller. The paint is then applied to a pair of idler rollers via the support roller, replacing manual spraying. This reduces the difficulty and labor intensity of painting, and also improves the uniformity of the paint application on the idler roller surface, ensuring the smoothness and aesthetics of the idler roller surface.

[0010] As a preferred embodiment, a further technical solution of this utility model is:

[0011] Preferably, the material tray has a structure that is narrow at the bottom and wide at the top. The top two ends of the material tray are respectively provided with outer edges, and the support frame is provided with support guide rods that are adapted to the outer edges. The material tray is slidably connected to the support guide rods through the outer edges.

[0012] Preferably, the bottom of the material tray is provided with a discharge port.

[0013] Preferably, handles are provided on the front and rear outer walls of the material tray.

[0014] Preferably, each support guide rod has a connector at both ends, an adjustment elongated hole is provided on the connector, and a locking bolt that mates with the adjustment elongated hole is provided on the support frame.

[0017] Preferably, the support frame has an adjustment elongated hole 2 at the installation position corresponding to the bearing seat 2, and the bearing seat 2 is connected to the support frame through the cooperation of the bolt assembly and the adjustment elongated hole 2.

[0018] Preferably, the lengths of the drive roller, support roller one, and support roller two are all greater than the length of the idler roller.

[0019] Preferably, the surface of the active roller is provided with a roller brush, and the surfaces of the first support roller and the second support roller are made of rubber. Attached Figure Description

[0027] 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.

[0028] like Figures 1 to 6 As shown, a roller surface coating device includes a support frame 1, which consists of a top frame 101 and four legs 102 placed at the four corners of the top frame 101. Adjacent legs 102 are fixedly connected by connecting rods 103, and each leg 102 has a pad 104 at its bottom.

[0029] An active roller 2 is horizontally arranged inside the top frame 101. The two ends of the central shaft of the active roller 2 are rotatably connected to the two ends of the top frame 101 through bearings.

[0030] Support roller 1 3 and support roller 2 4 are installed on the top frame 101. The outer edge of support roller 1 3 contacts the outer edge of drive roller 2. The two ends of the central shaft of support roller 1 3 are connected to the top frame 101 through bearing seat 1 5, and the two ends of the central shaft of support roller 2 4 are connected to the top frame 101 through bearing seat 2 6.

[0031] In this embodiment, in order to meet the requirements of painting rollers of different diameters, the distance between support roller 3 and support roller 4 is adjustable. Specifically, the top frame 101 has adjustment elongated holes 7 at both ends corresponding to the bearing seat 6. The bearing seat 6 is connected to the top frame 101 through bolt assemblies that cooperate with the adjustment elongated holes 7. The installation position of the bearing seat 6 is adjusted by adjusting the adjustment elongated holes 7, thereby adjusting the position of the support roller 4 and completing the adjustment of the distance between support roller 3 and support roller 4.

[0032] In this embodiment, the lengths of the drive roller 2, support roller 1 3, and support roller 2 4 are all greater than the length of the idler roller cylinder, so as to ensure that the outer surface of the idler roller cylinder can be completely painted.

[0033] The surface of the drive roller 2 is provided with a velvety brush (similar to the brush of a paint roller), while the surfaces of the support roller 3 and the support roller 4 are made of smooth rubber.

[0034] A drive unit is installed on one side of the support frame 1. The drive unit consists of a drive motor 8, a reducer 11, a drive sprocket 9, and a driven sprocket 10. The drive motor 8 and the reducer 11 are connected to the support frame 1. The output end of the drive motor 8 is connected to the input end of the reducer 11, and the output end of the reducer 11 is connected to the drive sprocket 9. The drive sprocket 10 is installed on the central axis of the drive roller 2, support roller 3, and support roller 4, respectively, corresponding to the end of the drive sprocket 9. The drive sprocket 9 is connected to the driven sprocket 10 in sequence via a chain. When the drive motor 8 rotates, it drives the drive sprocket 9 to rotate through the reducer 11. The drive sprocket 9 then drives the driven sprocket 10 to rotate through the chain, thereby driving the drive roller 2, support roller 3, and support roller 4 to rotate.

[0035] Inside the support frame 1, below the active roller 2, there is a material tray 12. The installation height of the material tray 12 is required to ensure that the lower end of the active roller 2 can be immersed in the paint in the material tray 12, and the material tray 12 does not interfere with the rotation of the active roller 2. The material tray 12 has a structure that is narrow at the bottom and wide at the top. The left and right ends of the top of the material tray 12 are respectively provided with outer edges 13 along its width direction. Several reinforcing ribs are welded between the outer edges 13 and the outer wall of the material tray 12 at intervals.

[0036] The support frame 1 is provided with a support guide rod 14 that is adapted to the outer edge 13. The material tray 12 is slidably connected to the support guide rod 14 through the outer edge 13. Connectors 15 are fixedly connected to both ends of the support guide rod 14. The connectors 15 are detachably connected to the corresponding legs 102 on their respective sides. Specifically, each connector 15 is provided with an adjustment elongated hole 16 vertically, and each leg 102 is provided with a locking bolt 20 that is adapted to the adjustment elongated hole 16. After adjusting the height position of the connector 15 through the adjustment elongated hole 16, the connector 15 is locked to the leg 102 using the locking bolt 20.

[0037] In this embodiment, a discharge port 17 is also provided at the bottom of the material tray 12. The discharge port 17 is equipped with a valve 18 for controlling the unloading of materials so as to facilitate the cleaning of the material tray after the equipment is used.

[0038] Handles 19 are welded to the outer walls on the front and rear sides of the material tray 12 to facilitate pulling out and moving the material tray 12.

[0039] In application, the height of the material tray 12 is adjusted according to the outer diameter of the drive roller 2 so that the outer edge of the drive roller 2 can be immersed in the paint. The distance between the support roller 1 3 and the support roller 2 4 is adjusted according to the diameter of the idler roller. The drive motor 8 is started, and the drive motor 8 drives the drive roller 2, support roller 1 3 and support roller 2 4 to rotate through the reducer 11 and sprocket chain transmission. While the drive roller 2 rotates, the brush on its surface comes into contact with the paint. Then, the brush with paint comes into contact with the surface of the support roller 1 3 and applies the paint to the surface of the support roller 1 3. The idler roller is placed on the support roller 1 3 and the support roller 2 4. The idler roller also rotates with the rotation of the support roller 1 3 and the support roller 2 4. During the rotation of the idler roller, the paint on the surface of the support roller 1 3 comes into contact with the idler roller to complete the painting.

[0040] In this invention, the active roller picks up paint from the upper part of the tray when it rotates. When the amount of paint in the tray decreases, the height of the tray can be adjusted to ensure that the brush of the active roller is in contact with the paint. In order to improve the utilization rate of the paint in the tray and avoid wasting paint, the tray is designed as a structure that is narrow at the bottom and wide at the top. When the amount of paint in the tray decreases, the paint can be concentrated at the bottom of the tray.

[0041] This invention applies paint from a material tray to the surface of a support roller by having the paint come into contact with the support roller. The support roller then applies the paint to the surface of a pair of idler rollers, replacing manual spraying. This reduces the difficulty and labor intensity of painting, improves the uniformity of the paint application on the roller surface, increases the efficiency of painting the idler roller surface, and ensures the smoothness and aesthetics of the idler roller surface.

[0042] The above description is merely a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
