Description

Technical Field

[0001] The utility model relates to the technical field of open mixing mills, in particular to an open mixing mill for PVC plastic floors. Background Art

[0002] The open mill is the abbreviation of an open plastic refining machine. The main working parts of the open mill are two hollow rollers or drilled rollers rotating inward in opposite directions. The one installed on the operator's side is called the front roller, which can be moved horizontally back and forth by manual or electric action to adjust the roller spacing to meet the operating requirements; the rear roller is fixed and cannot move back and forth. The two rollers are generally the same size and rotate relative to each other at different speeds. The raw rubber or rubber material is drawn into the gap between the two rollers as the rollers rotate, and is subjected to strong shearing to achieve the purpose of plasticization or mixing. The existing open mills used for plastic flooring have the problems of poor rubber processing effect, the inability to adjust the spacing between the two hollow rollers or drilled rollers rotating inward in opposite directions, and poor applicability. Therefore, a kind of open mill for PVC plastic flooring is needed.
