Description

Double-roller rubber open mill

Technical Field

The utility model relates to the technical field of rubber production, in particular to a double-roller rubber open mill.

Background

The open mill is a roller exposed rubber mixing device for mixing and discharging rubber, in rubber mixing, two rollers which rotate at different speeds are used for bringing rubber into between the rollers, rubber is extruded and wrapped on the surface of one of the rollers due to adhesion, certain stacking rubber is kept on the upper surface between the two rollers, after compounding agent is added, the compounding agent enters into a deep rubber surface layer in the pressure and continuous turning process of the stacking rubber, under the dual effects of pressure and shearing force, the compounding agent entering into the surface layer is continuously increased, and at the moment, if the rubber is taken out for observation, the layering state can be obviously seen, and the mode is laminar flow mixing in mixing.

However, in mixing in an open mill, if the mixing is only performed by laminar flow, the compounding agent is difficult to disperse uniformly and the mixing speed is slower, so that the compounding agent is generally turned over by external force at present, that is, the compounding agent can enter the rubber material quickly and fully dispersed by turning over the rubber material, that is, the dispersing mixing is performed, but most of the conventional double-roller rubber open mills in the market do not have the effect of automatic turning over, so that most of the conventional double-roller rubber open mills still need to be turned over by manpower, workers attach to the roller by using a handheld cutter, the rubber material adhered to the surface of the roller is horizontally cut in the process of rotating the roller, then the cutter is quickly put down, the rubber material is collided by two hands, the rolling situation occurs in the process of rolling over the rubber material, after the rolling to a certain extent, the rubber material is upwards supported and pushed to the upper part of the joint position of the two rollers, the rubber material is enabled to enter the gap between the two rollers again in a stacking manner for extrusion and laminar flow mixing, and the manner does not only need to keep high concentration of the workers (the rubber cutting is needed to complete at a quick speed, otherwise, the situation of cutting the two arms can be broken in the whole process of cutting the rubber material can occur in the process of rotating the rubber material, and the whole process of the process is low in the process of acid can occur.

Therefore, it is necessary to provide a new twin-roll rubber mill to solve the above technical problems.
