Description

Technical Field

[0001] The utility model relates to the technical field of rubber rollers, in particular to a high-stability nitrile rubber roller. Background Technique

[0002] A nitrile rubber roller is a roller-shaped product with a metal or other material core and a covering made of nitrile rubber through vulcanization. The reason why a nitrile rubber roller requires high stability is mainly that it needs to face various complex environments and working conditions in actual applications. Therefore, a high-stability nitrile rubber roller is needed.

[0003] Currently, in occasions such as printing and dyeing that require long-term contact with high temperatures and oil substances, in a high-temperature environment, nitrile rubber is prone to thermal oxygen structuring. That is, as the temperature rises, the molecular chains of nitrile rubber will break and degrade due to heat, resulting in a decline in material properties. In the case of long-term contact with oil substances, the oil substances will penetrate into the interior of the nitrile rubber and interact with the rubber molecules, causing changes in the physical and chemical properties of the rubber, thereby reducing its oil resistance and affecting the stability of the rubber roller. For this reason, a high-stability nitrile rubber roller is proposed. Summary of the Invention

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art and propose a high-stability nitrile rubber roller.

[0009] Preferably, a top surface groove is opened inside the device frame. The partition plate is installed between the inner walls of the top surface groove. The partition plate divides the top surface groove into a cleaning groove and an application groove. The cleaning block is movably connected in the cleaning groove, the application block is movably connected in the application groove, and the bottom surfaces of the application block and the cleaning block are both adapted to the rubber roller body.

[0011] Preferably, sliding grooves are symmetrically formed on the cleaning tank, the coating tank and the partition plate, and both ends of the cleaning block and the coating block are slidably connected in the sliding grooves.

The rubber roller can be soaked in the cleaning tank, the cleaning block can clean the dirt after soaking, the coating block can evenly apply the raw lacquer in the coating tank so that it penetrates into the interior, and the raw lacquer is dried by the heating plate on the other side.

[0015] In this solution, the possibility that the nitrile rubber roller is prone to thermal oxidation structuring in a high-temperature environment is reduced, and as the temperature rises, the molecular chains break and degrade, reducing the possibility that oil substances will penetrate into the nitrile rubber interior, improving the spinnability of the nitrile rubber roller, reducing the friction coefficient, reducing static electricity accumulation, and also improving the oil resistance and heat resistance of the rubber roller, making its service life longer.

A blower 6 is installed on one side of the support plate to achieve rapid drying. The blower 6 is arranged on the device frame 1, a heating plate 4 is installed on the device frame 1, a partition board 14 is installed in the device frame 1, a cleaning block 13 and a coating block 12 are movably connected to both sides of the partition board 14 respectively, a heat conduction block 5 is installed on one side of the cleaning block 13, a lead screw 15 is rotatably connected between the inner walls of the device frame 1, a transmission belt 11 is connected to one end of the lead screw 15, rotating rollers 2 are fixedly installed on both sides of the rubber roller body 3, and both ends of the device frame 1 are connected to the outer surface of the rotating roller 2 to prevent the device frame 1 from moving simultaneously during the rotation process. The device frame 1 is adapted to the rubber roller body 3 to reduce the possibility of internal liquid leakage. Sliding grooves are symmetrically opened on the cleaning groove, the coating groove and the partition board 14, and both ends of the cleaning block 13 and the coating block 12 are slidably connected in the sliding grooves, which can make the moving process of the cleaning block 13 and the coating block 12 more stable, and achieve stable cleaning and uniform coating.

[0023] In this embodiment, a top surface groove is formed in the device rack 1. The partition plate 14 is installed between the inner walls of the top surface groove. The partition plate 14 divides the top surface groove into a cleaning groove and an application groove. The cleaning block 13 is movably connected in the cleaning groove, and the application block 12 is movably connected in the application groove. The bottom surfaces of the application block 12 and the cleaning block 13 are both adapted to the rubber roller body 3 to avoid missing areas. The heat conducting block 5 is installed on the inner wall of the cleaning groove and is fixedly installed on the device rack 1, which facilitates the heat of the heating plate 4 on one side to heat and keep warm the liquid in the cleaning groove when preheating the rubber roller body 3, avoiding the possibility of the rubber roller body 3 cooling during the cleaning process. Liquid filling ports 8 are installed on the top surfaces of the cleaning groove and the application groove. The liquid filling ports 8 penetrate to the outside of the device rack 1 to facilitate the addition of cleaning liquid and raw lacquer. Drain pipes 7 are installed on one side of the cleaning groove and the application groove, and the drain pipes 7 also penetrate to the outside of the device rack 1.

During the preheating process, the heat generated by the heating plate 4 will heat the heat conducting block 5. After preheating, the device rack 1 will first contact the rubber roller body 3 and scrape the impurities on its outer surface for the first time, and then enter the cleaning groove. If there are not many impurities on the outer surface of the rubber roller body 3, the cleaning block 13 will directly scrape the impurities on the outer surface. When the impurities are difficult to handle, the cleaning liquid can be discharged through the liquid filling port 8 to soak the rubber roller body 3, and the heat conducting block 5 will keep the liquid warm. During the soaking process, the cleaning block 13 will continuously scrape the impurities. After cleaning, it will rotate to the application groove, add raw lacquer through the liquid filling port 8, and under the back-and-forth application of the application block 12, the raw lacquer will penetrate into the rubber roller body 3. After the application is completed, it will rotate out, and the heating plate 4 and the blower 6 on the other side will dry the raw lacquer.
