Abstract

The invention provides an extruder head and an extruder. The extruder head comprises a front head mold, a rear head mold, a runner inserting component, damping blocks and a square-shaped component; the front head mold and the rear head mold are openably arranged; a first axial hole is formed on the middle part of the front head mold; a second axial hole is formed on the middle part of the rear head mold; the runner inserting component is inserted into the second axial hole; the runner inserting component comprises a first inserting block and a second inserting block; a glue draining runner isarranged between the first inserting block and the second inserting block; the damping blocks in various sizes are selectively fixed in the glue draining runner; the square-shaped component is arranged on the rear head mold; a glue outlet which is connected with the glue draining runner is formed on the square-shaped component. The extruder head provided by the invention can be used for solving the problems at the aspects of shape, size, uniformity, and the like, of wide products produced by a small-size extruder, and can finally realize high efficient production of wide slice products.

Description

technical field [0001] The invention relates to the technical field of film production devices, in particular to an extruder head and an extruder. Background technique [0002] The extrusion molding method processes rubber and thermoplastics, and the head of the extruder determines the quality factors such as the shape, size, and compactness of the final product. Nowadays, the rubber and plastic related product industries have higher and higher requirements for the shape, dimension diversity and product stability of products, as well as higher and higher production efficiency requirements. The traditional extrusion calendering method has many problems such as high cost, unstable product quality, difficulty in product change, large floor space, and low efficiency. [0003] Extrusion and calendering are generally used in the production of wide-width thin films by existing extruder heads. The extruder head is generally a separate structure of upper and lower dies. The hydrauli...
