Description

Technical Field

[0001] The utility model relates to the technical field of three-roller grinding devices, in particular to a three-roller grinding machine which is easy to adjust. Background Art

[0002] Masterbatch, also called color seed, is a new type of colorant specially used for polymer materials. It is composed of three basic elements: pigment or dye, carrier and additive. During production, it is mostly ground and mixed together through a three-roll grinder.

[0003] In the existing three-roller grinders, the gaps between the grinding rollers are mostly fixed. The operation process for adjustment is cumbersome and complicated, and it takes a long time, which increases the workload of the operator and affects the work efficiency of the three-roller grinder when it is actually used. In addition, the existing three-roller grinders are generally driven by a single servo motor to drive the three grinding rollers to rotate at the same time. The servo motor needs to bear a heavy burden, resulting in the need for frequent maintenance of the servo motor in the later stage. The service life of the servo motor is short, which affects the service life of the three-roller grinder when it is actually used. For this reason, we propose a three-roller grinder that is easy to adjust. Utility Model Content
