Description

Technical Field

[0001] This utility model belongs to the field of flooring processing technology, and more specifically, it relates to a two-roll mill suitable for flooring of different thicknesses. Background Technology

[0002] Open mixing is a manufacturing process for flooring linoleum, mainly including steps such as ingredient mixing, internal mixing, open mixing, calendering, cutting, die laying, and hydraulic pressing. Among these, open mixing is a crucial step, its main purpose being to ensure the ingredients are mixed evenly and to adjust parameters such as the hardness and viscosity of the raw material, preparing it for subsequent calendering and cutting steps. Existing open mixing machines for flooring linoleum processing typically employ relative rotational motion between two mixing shafts to achieve this process.

[0003] Current open mills still have the following shortcomings:

[0004] 1. Due to the inconsistent thickness of floor coverings, the heating speed of thicker floor coverings is slower during the annealing process, which affects the overall production efficiency and has certain limitations.

[0005] 2. In the heating process, the required spacing between heating rollers may vary depending on the thickness of the flooring to ensure uniform and sufficient heating. However, existing equipment typically uses heating rollers with a fixed spacing, making it difficult to dynamically adjust according to the thickness of the flooring. This may result in uneven heating, localized overheating, or insufficient heating of the flooring, which in turn affects the plasticizing and mixing effect of the flooring, reducing product consistency and quality stability.
