Controllable magnetic circuit permanent magnet suspension carrier roller

Abstract

The invention relates to the technical field of magnetic suspension carrier rollers, in particular to a controllable magnetic circuit permanent magnetic suspension carrier roller which comprises a carrier roller body, a sliding installation base assembly, a magnetic suspension assembly and a fixed installation base. According to the controllable magnetic circuit permanent magnetic suspension carrier roller, the inclined end face of a magnetizer 1 is represented as the N pole, and the inclined end face of a magnetizer 3 is represented as the N pole; large circles on the outer surfaces of the permanent magnet rings are also N poles, so that the same poles repel each other, the permanent magnet rings only have vertical upward force, the permanent magnet rings are suspended, and the carrier roller, the permanent magnet rings at the two ends and the carrier roller shaft sleeve assembly form a suspended whole, so that the feeding roller is suspended; therefore, the problems that in traditional mechanical connection, the friction force is large and abrasion is serious in the rotating process of the feeding roller are solved, the force needed when a material using mechanism pulls the feeding roller is reduced, the tension borne by materials in the feeding process is reduced, and the situation that the materials are deformed and broken due to pulling is improved.

technical field [0001] The invention relates to the technical field of magnetic suspension idlers, in particular to a controllable magnetic circuit permanent magnet suspension idler. Background technique [0002] Idler rollers are widely used in all walks of life. Commonly used support rollers for conveyor belt support and feed rollers for paper, film, cloth and other roll materials.

Problems solved by technology

[0003] In the production and processing of coiled materials, such as printing and coating of rolled film or paper, the material is wound on the roller, and the coil is pulled by the material mechanism of the equipment to drive the feeding roller to rotate and feed the material. The traditional feeding The material roller is mechanically connected to realize free rolling through the rolling bearing, and then the feeding mechanism drives the feeding roller to rotate and feed the material. During this process, the gravity generated by the weight of the material wound on the feeding roller acts on the feeding roller. The rotating joints at both ends increase the static friction and sliding friction of the feeding roller, so that the tension on the material between the feeding roller and the feeding mechanism increases, and the equipment feeds intermittently. For permanent feeding, the pulling force provided by the feeding mechanism changes periodically, and the tension on the material also changes accordingly. When the feeding roller is worn, the static friction at both ends of the feeding roller will further increase, which will lead to When the material mechanism drives the feed roller to rotate, the ultimate tension on the material increases, so the material will be pulled, deformed or even torn during work, which will affect the quality of the product. Once the material is damaged, it will cost It takes a lot of time to replace and maintain equipment, so in order to ensure production efficiency and production quality, it is very important to keep the tension on the material constant;
