Technical Field

[0001] The utility model relates to the technical field of hot rolling mills, in particular to a circulating heat supply structure of a hot rolling mill used for producing non-woven fabrics. Background Art

[0002] Non-woven fabrics are a new type of textile material, also known as "non-textiles". Unlike traditional textiles, non-woven fabrics are not made of filaments, short fibers, cotton and other fibers through spinning, weaving and other processes, but are made by directly using chemical fiber particles, short fibers, etc. through pressing, hot melting, gluing and other processes. In order to improve the uniformity of the product and prevent the non-woven fabric from plastic deformation, the hot rolling roller needs to be evenly heated during processing. In traditional non-woven fabric production, hot rolling mill is one of the commonly used process equipment.

[0003] However, the hot rolling rollers of the existing hot rolling mills are heated by electric heating tubes, which often cannot achieve uniform heating of the hot rolling rollers, and easily lead to uneven temperature distribution on the roller surface, thereby affecting product quality, and even causing deformation and cracks on the roller surface due to uneven thermal stress. In view of the above problems, the inventors propose a circulating heat supply structure for hot rolling mills used in non-woven fabric production to solve the above problems. Utility Model Content

[0004] In order to solve the problem of uneven temperature distribution on the surface of the hot rolling roller when the hot rolling roller is heated by an electric heating tube, the utility model aims to provide a circulating heat supply structure of a hot rolling mill for the production of non-woven fabrics.

The connecting pipe 3 and the movable plate 10 are rotatably connected. A threaded rod 11 is threadedly connected to the top of one of the mounting plates 1, and the bottom end of the threaded rod 11 is rotatably connected to the top of the movable plate 10, and a turntable 12 is fixedly connected to the top of the threaded rod 11.

[0020] By adopting the above technical solution, by rotating the turntable 12, the threaded rod 11 is driven to move vertically, thereby driving the movable plate 10 to move vertically along the inner wall of the slide groove 9, and adjusting the hot rolling roller body 2 to a suitable position according to needs.

[0021] The movable plate 10 is fixedly connected to a connecting block 13 on one side away from the hot rolling roller body 2, and a rotating joint 14 is fixedly connected to the top of the connecting block 13. The rotating joint 14 is rotatably connected to the outer side of the end of the connecting pipe 3 away from the hot rolling roller body 2, and the oil inlet pipe 4 and the oil outlet pipe 5 are rotatably connected to the corresponding rotating joint 14.

[0022] By adopting the above technical solution, the connecting pipe 3 is connected to the oil inlet pipe 4 and the oil outlet pipe 5 respectively by setting the rotating joint 14, so that when the connecting pipe 3 rotates, the oil inlet pipe 4 and the oil outlet pipe 5 do not need to rotate, thereby ensuring the normal circulation of the oil.
