Abstract

The invention discloses a swimming roller of a medium-high calender, which is used in the technical field of swimming rollers, and comprises a central cylinder, a central shaft symmetrical about the central cylinder and a roller shell on the central cylinder, the central shaft is provided with a joint bearing, the joint of the roller shell and the central shaft is provided with a spherical ball bearing, and the swimming roller also comprises a pressure adjusting mechanism and a jumping prevention mechanism. The inner cavity of the roller body is divided, the circulating oil pressure part exists in the inwards-concave position, the pressure is more concentrated, and therefore the pressure distribution effect is better, upward arches are generated in the middle of the roller body to counteract the downward curvature generated by the roller body, it is guaranteed that products can be flatly and evenly pressed between the rollers, and the product quality is improved. When the swimming roller body rotates at a high speed, the roller shell has certain take-off potential energy, the take-off potential energy is counteracted by elastic potential energy borne by the take-off potential energy under the action of the roller jump prevention mechanism, and therefore the take-off prevention effect of the roller body during high-speed rotation is achieved, and rotation of the roller is more stable.

Description

technical field [0001] The invention is used in the technical field of swimming rollers, in particular to a swimming roller of a medium and high pressure polishing machine. Background technique [0002] The pressed product is formed by the opposite pressure between the pressing rollers of the medium and high pressure polishing machine, but with the increase of the width of the product, the length of the pressing roller also increases accordingly, so that the middle part of the pressing roller has a downward bending deflection, resulting in The two ends and the middle part of the roller are not uniformly pressed. During the rolling process, the various parts of the rolling mill are elastically deformed by the rolling force. These elastic deformations are finally reflected in the increase of the gap between the two rollers, resulting in Roll jump. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a swimming roller for a medium and high pre...
