Abstract

The invention discloses a molding process of calendering type grass green rubber surrounding bar rubber for liberation shoes. The molding process comprises the following steps: calendering rubber surrounding bar rubber by rollers of a calendering machine, wherein the roller distance of the rollers of the calendering machine is 1.8mm-2.0mm, the surface temperature of the upper roller is 80-85 DEG C, the surface temperature of the lower roller is 80-90 DEG C and the operation line speed of the rubber surrounding bar rubber is 0.2m / s-0.25m / s; cooling the rubber surrounding bar rubber calendered by the rollers by three surrounding bar cooling rollers for 1.5-2.0 minutes, wherein the surface temperature of the surrounding bar cooling rollers is 10-15 DEG C; and cutting the cooled rubber surrounding bar rubber to finish the molding process of the calendering type grass green rubber surrounding bar rubber for the liberation shoes.

Description

technical field [0001] The invention relates to the field of rubber material preparation, in particular to a process for extruding the calendered grass-green rubber surrounds for Jiefang shoes. Background technique [0002] Problems in the current laminating and molding process: the surface pattern of the rubber skirt is not clear enough, the size of the film fluctuates greatly, and the size is unstable, which affects the appearance quality of the rubber shoes. Contents of the invention [0003] The purpose of the present invention is to provide a rolling-type grass-green rubber wrapping molding process for Jiefang shoes. Its technical effect is: the surface pattern of the wrapping rubber sheet is clear and the size of the film is stable, so as to overcome the shortcomings of the prior art. [0004] The present invention is realized in this way: the rolling-type grass-green rubber wrapping rubber molding process for Jiefang shoes is first carried out by rolling the rubber ...
