Description

Technical Field

[0001] The utility model relates to the technical field of rubber mixing machine cutting, in particular to an adjustable cutting mechanism for a rubber mixing machine. Background Art

[0002] The open mixing mill, also known as the open rubber mixing mill, is one of the indispensable equipment in the rubber industry. It is mainly used in the preparation of plasticized rubber and mixed rubber, as well as in the process links of hot refining and molding. The core part of the equipment is the hollow roller or drilled roller that rotates inward at both ends. Among them, the roller facing the operator is called the front roller, which can be moved horizontally forward and backward manually or electrically to adjust the roller distance to meet different operating requirements. In contrast, the rear roller is fixed and cannot move forward and backward. The two rollers are usually the same in size and rotate relative to each other at different speeds. In this process, the raw rubber or rubber material will be drawn into the gap between the two rollers and subjected to strong shearing, thereby achieving the purpose of plasticization or mixing. It is worth mentioning that the open mixing mill is not only widely used in the rubber industry, but also plays an important role in fields such as plastic processing.

[0003] After the rubber sheet is pressed on the mixing mill, the operator needs to manually control the cutter to cut the rubber sheet. The cutting accuracy of the rubber sheet is low, the edges of the cut rubber sheet are uneven, and it cannot be accurately controlled. In addition, the manual cutting of the rotating roller will also cause certain harm. To this end, we provide an adjustable cutting mechanism for the rubber mixing mill to solve the above problems.
