Description

Technical Field

[0001] The utility model relates to the technical field of strip rubber processing, in particular to a rubber stripping knife. Background Art

[0002] The processing of many rubber products requires relatively narrow rubber strips. For example, rubber shock absorbers need to be injected by a glue injection machine. The width of the rubber strip is generally in the range of 30-50mm.

[0003] There are two methods for rubber stripping. One is to install multiple stripping knives on the mixing mill tray. When the rubber is wrapped on the mixing mill drum and rotated, it is cut into strips by the knife edge. The strip rubber is anti-sticked through the isolation agent pool. This method can ensure that all surfaces of the rubber strips are coated with isolation agent to avoid mutual adhesion. However, one disadvantage is that the scattered multiple rubber strips are easy to disperse, curl, and jam in the film cooling machine. Generally, multiple material collecting personnel are required to operate at the same time at the material collection point to ensure that the rubber strips are collected neatly and densely, which consumes a lot of manpower and has high labor intensity. The other method is to produce a whole wide rubber sheet on the mixing mill, and then use special stripping equipment to strip it after the collection is completed. This method can reduce the scattering of rubber strips, but the fresh rubber cut is very easy to stick because it is not coated with isolation agent, which causes inconvenience in subsequent operations. Therefore, a rubber stripping knife and a mixing mill are proposed to solve the above problems. Utility Model Content
