Abstract
The invention discloses a foam sheet extruder machine head. The foam sheet extruder machine head comprises a butt body, a shell and air flow pipeline, wherein the butt body is connected with the shell; a longitudinal cylindrical cavity is longitudinally formed in one end, close to the butt body, of the shell; a plurality of transverse cylindrical cavities are transversely formed in the shell; a plurality of transverse cylindrical cavities are parallel to each other; the head ends of the transverse cylindrical cavities are communicated with the longitudinal cylindrical cavity; the tail ends of the transverse cylindrical cavities are communicated with the outside of the shell; the air flow pipeline is matched with the cavity in the shell; the air flow pipeline is arranged at the middle position of the matched cavity; the shell comprises a heating chamber and a cooling chamber; the transverse cylindrical cavities penetrate through the heating chamber and the cooling chamber; the shell has a stepped shape which is vertically symmetrical; the heating chamber is higher than that of the cooling chamber. The foam sheet extruder machine head is simple in structure and high in work efficiency; and the quality of a micro-catheter foam sheet can be guaranteed.
Description
technical field [0001] The invention relates to an extrusion head, in particular to a foam sheet extrusion head. Background technique [0002] At present, plastic and rubber foam materials have been widely used in various packaging and cushioning fields. The processing equipment and technology of general foam sheet materials have become more and more mature. However, in the field of microcatheters, there are still large domestic Defects. Since microcatheters are mainly used in the field of modern medical technology, high requirements are placed on the quality of microcatheter foamed sheets, and thus high requirements are placed on the production tools of microcatheters foamed sheets. At present, there is no mature technology in China that can produce micro-catheter foam sheets with high quality and high efficiency. Contents of the invention [0003] In order to solve the above problems, the present invention provides a foam sheet extruder head. The foam sheet extruder h...
