Description

Technical Field

[0001] The utility model relates to the field of rubber rollers, in particular to a fixing tool for bonding and repairing rubber rollers. Background Art

[0002] Rubber rollers are mainly used in papermaking, dyeing, printing, grain processing, metallurgy, plastic processing, etc. Rubber rollers are roll-shaped products made of metal or other materials as the core and rubber covered by vulcanization. Rubber rollers are generally composed of an outer layer of rubber, a hard rubber layer, a metal core, a roller neck and vents. Its processing includes roller core sandblasting, bonding treatment, rubber forming, cloth wrapping, wire winding, vulcanization in a vulcanization tank and surface processing.

[0003] However, when rubber is squeezed, gas and volatiles may be generated inside it. These gases will form bubbles inside the rubber, affecting the quality and performance of rubber products. Therefore, in some cases, it is necessary to exhaust the rubber. During the extrusion process, for example, the extrusion temperature can be appropriately increased to make the gas and volatiles more easily evaporate. At the same time, the gas discharge can also be promoted by controlling the pressure. After the rubber is locally deformed by extrusion, the pattern will not be printed locally when dealing with some printing and dyeing work.
