Description

Technical Field

[0001] The utility model relates to the technical field of rubber-coated rollers, in particular to a rubber-coated roller with a rubber surface that is easy to replace. Background Art

[0002] Rubber rollers are stick-shaped products made of metal or other materials as the core and rubber covered by vulcanization. According to their uses, they can be divided into: papermaking rubber rollers, printing and dyeing rubber rollers, printing rubber rollers, etc. According to their surface morphology, they can be divided into: flat rollers and patterned rubber rollers. They involve more industries and are widely used. The rubber surface of commonly used rubber rollers is generally an integral structure with the rubber roller body. The rubber surface is attached to the outer surface of the rubber roller body. After long-term use, the rubber surface will wear out. In order to improve the efficiency of inspection and maintenance, a rubber-coated roller with an easy replacement of the rubber surface is often used.

[0003] The prior art discloses a rubber roller with a convenient rubber surface replacement, with publication number CN217328095U, comprising a rubber roller body and a rubber surface, wherein the outer surface of the rubber roller body is provided with a plurality of positioning grooves, the inner wall of the rubber surface is fixedly connected with a plurality of positioning plates, the outer surface of one end of the rubber roller body is fixedly connected with a baffle, the interior of the rubber roller body is provided with a plurality of limiting grooves, and the inner walls of the plurality of limiting grooves are fixedly connected with springs. The utility model has the advantages that the installation and removal of the rubber surface are relatively simple through the coordinated arrangement of the positioning grooves, positioning plates, baffles, springs, limiting blocks, movable rods, fixed plates, connecting rods, movable rings, pull rods, movable baffles and handles, so that the installation and removal of the rubber surface are relatively simple, so that the rubber roller body and the rubber surface are no longer an integral structure, and when the rubber surface is worn, it is convenient to remove the rubber surface and replace it with a new one, and there is no need to replace the entire rubber roller structure, which greatly saves resources and production costs.

[0004] When the above utility model is in use, a detachable movable baffle is used in conjunction with a spring, a movable plate and a fixed plate to facilitate the disassembly and installation of the rubber surface. However, the spring is a movable structure, and the fixed plate and the movable baffle are limited by abutment. The stability of the installation and fixing structure is poor. During the rotation of the rubber roller body and the shaft core, relative sliding is likely to occur between the fixed plate and the movable baffle, thereby affecting the normal installation and use of the rubber surface. The practicality is relatively general. Utility Model Content
