This invention provides a grinding device for the outer diameter of textile rubber rollers, belonging to the field of rubber roller processing technology. It includes a rubber roller grinding machine, whose inner wall is slidably connected to a feed mechanism via a linear guide rail. A first sliding frame is fixedly connected to the top of the feed mechanism. This invention, by setting a support mechanism, effectively solves the processing defects caused by uneven elastic deformation of the rubber roller, improving processing quality and work efficiency. The support mechanism, by setting a first extrusion roller, a second extrusion roller, and a third extrusion roller, simultaneously applies extrusion force from the bottom, opposite, and top of the grinding point, respectively, ensuring that the extrusion force is consistent with the grinding force. This suppresses elastic bulging deformation of the rubber roller, allowing the grinding force to act on the material for cutting and removal, ensuring that the actual grinding depth matches the feed rate, thereby improving the problem of uneven local grinding, and enhancing the surface finish, processing efficiency, and dimensional consistency of the rubber roller.

This utility model relates to a laminating machine, specifically, a metal plate surface laminating machine, including a frame, a drive roller, and a drive component.

This utility model uses a transmission component to drive two sliding tables to move synchronously in opposite directions or back to back, thereby causing the rotating roller to adapt to metal plates of different widths. Under the elastic action of a spring, the rotating roller tightly adheres to the surface of the metal plate, ensuring both effective clamping and positioning of the metal plate and synchronous rotation with the metal plate to assist in transmission. This effectively solves the problems of easy deviation and inaccurate positioning during metal plate transmission, ensuring that the metal plate enters the laminating mechanism with a precise posture.
