Problems solved by technology

[0004] However, in this technical solution, in the trimming process, the rubber needs to be fixed again, and the positioning process is complicated, and it is impossible to realize the direct positioning of the rubber ring in the mold after extrusion molding. It can be applied to circular sealing rings with no protrusions on the outside. When encountering a sealing ring with protrusions on the round surface, this solution cannot be applied, the application range is narrow, and the trimming effect is poor

Abstract

The invention provides trimming equipment for a door sealing ring of a roller washing machine, which is characterized by comprising a feeding component, a discharging component and a trimming component, the trimming assembly is arranged at the side part of the feeding assembly; the pressing assembly is arranged at the lower part of the feeding assembly; the discharging assembly is arranged at the lower part of the pressing assembly; the trimming assembly comprises a first trimming mechanism, a second trimming mechanism, a third trimming mechanism and a protrusion trimming mechanism. The second trimming mechanism is rotationally arranged in the first trimming mechanism; the first trimming mechanism and the third trimming mechanism are arranged in parallel; the protrusion trimming mechanism is arranged in the second trimming mechanism. Trimming is carried out in a cooperative mode of the first trimming mechanism, the second trimming mechanism and the third trimming mechanism, and the effects that trimming can be carried out layer by layer, and the trimming range is wide are achieved.

Description

technical field [0001] The invention relates to the technical field of sealing ring processing, in particular to a device for trimming the door sealing ring of a drum washing machine. Background technique [0002] In the production process of the rubber sealing ring of the drum washing machine, the rubber raw materials are usually mixed, banburyed, cooled, extruded and other steps are required. Among them, after the extrusion molding process is completed, the rubber ring is usually taken out of the mold. Then trim the edge of the rubber to make the processed rubber ring more beautiful and meet the work requirements. [0003] Chinese patent CN 113386014 B discloses a device for removing burrs after molding rubber sealing rings of petroleum machinery, including a base, a fixing unit and a grinding unit, the upper end of the base is provided with an annular groove, and the fixing unit is arranged in the annular groove. The grinding unit is arranged on the fixing unit; the pres...
