Description

Technical Field

[0001] The utility model relates to the technical field of acetate fiber rubber sheet production, in particular to an extruder for acetate fiber rubber sheet production. Background Art

[0002] Cellulose acetate refers to a thermoplastic resin obtained by esterification with acetic acid as solvent and acetic anhydride as acetylating agent under the action of a catalyst. Cellulose acetate sheet is a common building material, usually used in building structures such as walls, floors and ceilings.

[0003] Cellulose acetate rubber sheet has the characteristics of fire resistance, water resistance, corrosion resistance, earthquake resistance, and heat insulation. It has been widely used in the construction field. In the production process of cellulose acetate rubber sheet, a calender is used to process it. The calender is also called a roller press or a rolling mill. Because it squeezes the material through two rollers and pushes it out, it is also called a sheet extruder.

[0004] Existing extruders for producing cellulose acetate sheets include hot pressing and cold pressing. However, the existing hot pressing extruders use heated rollers to heat press the sheets, and the heated rollers have low heating efficiency for the sheets, which reduces the calendering efficiency of the cellulose acetate sheets. Therefore, we propose an extruder for producing cellulose acetate sheets. Utility Model Content

[0017] The heated acetate sheet extends from the discharge chute and moves between the bearing roller and the nip roller, where it is extruded and calendered by the nip roller and the bearing roller. A person holds the rocker and rotates the screw rod to push the structural frame and the nip roller inside it up and down, so that the distance between the nip roller and the bearing roller can be adjusted according to the thickness of the acetate sheet or the process requirements.
