Abstract
The utility model discloses a kind of film extrusion machine head, comprise head and lower head, sizing material import is provided with in the middle part of head one end, upper head and lower head are installed on headstock, headstock connects locking cylinder, be provided with runner between upper head and lower head, runner is be the structure extended in streamlined outside both sides by centre, is provided with damping block in runner.Film extrusion machine head of the present utility model, sizing material enters runner from middle part, forces shunting by damping block, material is streamlined expansion to both sides, and stream resistance is little and smooth and easy, makes film export each point flow velocity consistent, ensure that broad-amplitude film is evenly extruded, improve production efficiency and film quality.
Description
Technical field
The utility model relates to rubber tooling field, particularly relates to film extrusion machine.
Background technology
Wide-film extruder is the capital equipment adopting extrusion calendaring to produce broad-amplitude film, adopts extrusion calendaring production broad-amplitude film significantly can improve product quality and the production efficiency of film.But traditional film extrusion machine head structure and flow passage structure are unfavorable for that sizing material flows, cause film to export each point flow velocity inconsistent, can not ensure that broad-amplitude film evenly flows out, reduce production efficiency and film quality.
Utility model content
In order to overcome the inconsistent problem causing broad-amplitude film evenly not flow out of film outlet each point flow velocity in conventional film cross-head, the utility model provides a kind of film extrusion machine head.
The technical scheme that the utility model is adopted for achieving the above object is: film extrusion machine head, comprise head 1 and lower head 2, sizing material import 6 is provided with in the middle part of head one end, upper head 1 and lower head 2 are installed on headstock 4, headstock 4 connects locking cylinder 5, is provided with runner 7 between upper head 1 and lower head 2.
Described runner 7 is be the pyramidal structure extended in streamlined outside both sides by centre.
Damping block is provided with in described runner 7.
Described upper head 1 and lower head 2 junction are provided with die panel 3.
Film extrusion machine head of the present utility model, sizing material enters runner from middle part, forces shunting by damping block, material is streamlined expansion to both sides, and stream resistance is little and smooth and easy, makes film export each point flow velocity consistent, ensure that broad-amplitude film is evenly extruded, improve production efficiency and film quality.
Accompanying drawing explanation
Fig. 1 is the utility model film extrusion machine head overall structure figure.
Fig. 2 is the main pseudosection of the utility model film extrusion machine head.
Fig. 3 is the utility model film extrusion machine head top view.
Detailed description of the invention
Film extrusion machine head structure of the present utility model as Figure 1-3, film extrusion machine head, comprise head 1 and lower head 2, be provided with sizing material import 6 in the middle part of head one end, upper head 1 and lower head 2 are installed on headstock 4, and headstock 4 connects locking cylinder 5, runner 7 is provided with between upper head 1 and lower head 2, runner 7 is be the pyramidal structure extended in streamlined outside both sides by centre, and be provided with damping block in runner 7, upper head 1 and lower head 2 junction are provided with die panel 3.
Film extrusion machine head of the present utility model, sizing material enters runner 7 from the sizing material import 6 at middle part, forces shunting by damping block, material is streamlined expansion to both sides, stream resistance is little and smooth and easy, makes film export each point flow velocity consistent, ensures that broad-amplitude film is evenly extruded.
