Description

Technical Field

[0001] The utility model belongs to the technical field of rubber processing, and in particular relates to an open mixing mill which is convenient for rubber material recovery. Background Art

[0002] Rubber mixers are divided into two types: open type and closed type. The open type is mainly used for rubber heat refining, sheeting, rubber breaking, plastic refining and mixing. The open type has been used in production since 1826. Its structure is relatively simple and it is still widely used today. The closed type is mainly used for rubber plastic refining and mixing. It has one more mixing chamber than the open type.

[0003] The authorization publication number "CN220162909U" records that "the utility model relates to the field of rubber mixing machines, specifically a rubber mixing machine that is easy to use, including a base, a casing is fixed on the top of the base, and a rubber mixing roller is symmetrically rotatably installed on the upper side of the inner cavity of the casing, and a feed hopper is fixed through the middle of the top of the casing, and two symmetrically arranged first guide rollers are rotatably installed on the lower side of the inner cavity of the casing, and through holes are opened on the lower sides of the two side walls of the casing, and an adjustment plate is fixed on the inner wall of the through hole, and a shovel plate is connected to the top of the adjustment plate. After the two rubber mixing rollers are used to mix and shape the raw materials, the utility model can use the shovel plates on both sides to fit the surface of the formed strip-shaped rubber material, so as to pour the fallen granular raw materials out of the outside of the casing, and at the same time, the granular raw materials adhering to the surface of the strip-shaped rubber material can be shoveled out and exported, thereby ensuring the thoroughness of the raw material recycling. At the same time, there is no need to collect the granular raw materials with a collection plate, thereby improving the convenience of operation."

[0004] The above-mentioned device is to adhere the shovel plate fixedly connected to the top of the adjustment plate to the surface of the rubber material, pour the formed rubber material out of the outer side of the casing, and at the same time shovel and export the granular raw materials adhering to the surface of the rubber material, so as to achieve the purpose of recycling the raw materials. However, when the above-mentioned device is in use, the gap between the two rollers will squeeze the rubber material to generate high temperature, which will cause a large amount of rubber material to adhere to the surface of the roller and be difficult to remove, further resulting in insufficient subsequent rubber extrusion, and the adhered rubber material is not easy to clean, which will greatly reduce production efficiency. Utility Model Content
