Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing and pelletizing, in particular to a pelletizer for rubber processing. Background Art

[0002] Rubber processing is the process of making rubber into rubber products. The basic process of processing various rubber products includes plasticizing, mixing, calendering or extrusion, molding and vulcanization. Each process has different requirements for the product and is combined with a number of auxiliary operations. Among them, rubber pelletizing is convenient for heating and melting plastic particles.

[0003] However, the following problems still exist in actual use:

[0004] The existing pelletizing device first needs to split the rubber strips into thin strips and then perform the pelletizing operation. However, the height of the splitting roller cannot be changed during use, resulting in the inability to change the height according to the thickness of the rubber strips during the splitting process, causing some rubber strips to be incompletely split, resulting in the inability to perform subsequent pelletizing normally. At the same time, pelletizing is mostly performed in a single-knife manner. Single-knife cutting is not only easy to damage the sharpness of the blade, but also if the knife force is not enough, it will lead to the inability to perform pelletizing normally, affecting the overall processing progress.
