Abstract
Description
Technical Field
[0001] This utility model relates to the field of roller technology, and in particular to a stable high-temperature resistant roller. Background Technology
[0002] In many industrial production processes, materials need to be transported in high-temperature environments. For example, in steel production, steel billets need to be transported to rolling mills at high temperatures for rolling. Therefore, a type of conveyor roller that can operate stably in high-temperature environments is required.
[0003] Traditional rollers are mostly one-piece structures with no internal heat dissipation structure. When conveying materials with high temperature, the rollers may deform or be damaged. They may also increase the friction between the material and the roller, resulting in wear, scratches and other damage to the material surface.
[0004] Therefore, those skilled in the art have provided a stable high-temperature resistant roller to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stable high-temperature resistant roller. This roller has an internal oil storage chamber that allows oil to be introduced through an oil inlet. The oil in the storage chamber absorbs the heat transferred by the material during the conveying process, effectively reducing the roller's temperature. Furthermore, multiple ventilation holes are provided along the roller's sides, allowing the interior to contact the outside air for heat dissipation. This addresses the deficiency of traditional rollers, which are mostly one-piece structures lacking internal heat dissipation mechanisms.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A stable high-temperature resistant roller includes a roller body, with mounting shafts integrally provided at both ends of the roller body. Multiple ventilation holes are evenly opened inside the roller body, each ventilation hole penetrating the roller body. An oil storage chamber is opened inside the roller body, and a pressure relief valve is installed at one end of the mounting shaft.
[0008] Through the above technical solution, by opening an oil storage chamber inside the roller and introducing oil into it through the oil injection port, the oil in the oil storage chamber can absorb the heat transferred by the material during the conveying process, thereby effectively reducing the temperature of the roller. At the same time, multiple ventilation holes are opened on the side of the roller throughout the entire roller, which can allow the inside of the roller to contact the outside air for heat dissipation. The design of the pressure relief valve can prevent the oil temperature inside the roller from rising and causing excessive pressure.
[0009] Furthermore, an oil inlet is provided on the middle of one side of the top of the roller body, which is connected to the oil storage cavity. A sealing cap is threaded onto the top of the oil inlet, and threads are provided on both the inner wall of the oil inlet and the outer side of the sealing cap.
[0010] Through the above technical solution, an oil inlet is provided on the middle of one side of the top of the roller body, which is connected to the oil storage cavity, to facilitate the addition and removal of oil from the oil storage cavity. A sealing cap is threaded on the top of the oil inlet, and threads are provided on both the inner wall of the oil inlet and the outer side of the sealing cap to facilitate sealing the oil inlet.
[0011] Furthermore, a connecting air duct is provided at the inner middle of the roller body, and the connecting air duct has the same diameter as multiple ventilation holes;
[0012] Through the above technical solution, a connecting air duct is opened in the middle of the inside of the roller body, and the connecting air duct has the same diameter as multiple ventilation holes, so that multiple ventilation holes can be connected to improve the heat dissipation effect.
[0013] Furthermore, a transmission gear is integrally provided at the end of the roller body away from the oil injection port;
[0014] Through the above technical solution, a transmission gear is integrally set at the end of the roller body away from the oil injection port, so that it can be transmitted with the drive equipment via gear transmission.
[0015] Furthermore, positioning grooves are provided at the top ends of both mounting shafts;
[0016] The above technical solution provides positioning grooves at the top of both mounting shafts to facilitate engagement with the drive device.
[0017] Furthermore, the surface of the roller body is coated with a ceramic coating;
[0018] By applying the above technical solution, a ceramic coating is applied to the surface of the roller body, thereby improving the heat resistance of the roller body.
[0019] This utility model has the following beneficial effects:
[0020] 1. This utility model proposes a stable high-temperature resistant roller. By opening an oil storage chamber inside the roller and introducing oil into it through an oil injection port, the oil in the storage chamber can absorb the heat transferred by the material during the conveying process, thereby effectively reducing the temperature of the roller. At the same time, multiple ventilation holes are opened on the side of the roller throughout the entire roller, allowing the inside of the roller to contact the outside air for heat dissipation. Furthermore, this roller can be connected to the drive equipment via a mounting shaft or via gear transmission, improving the roller's flexibility. Attached Figure Description
