(2) background technology:
Broad-amplitude film (particularly conveyer belt manufacturing with) production equipment comprises calender and to the extrusion equipment of calender feed, the international at present maximum extrusion equipment in usefulness is ￠ 250 extruders, and join an extruder head, because the film wide cut that has is up to 2500mm, then extruder head will be accomplished the 3000mm width at least.
Extrusion equipment produces inevitable subject matter therefrom:
1, the extruder head size is huge, complex structure, design, manufacturing processing difficulties.The Breadth Maximum of the film of being produced is restricted.
2, the enormous size of runner plate causes installing and to change required non-cutting time long, and labour intensity is big.
3, because the characteristics of film production are multi-varieties and small-batches, when therefore producing the film of different specification size with the extrusion equipment of producing broad-amplitude film, need to increase a lot of aided processes, obviously efficient is too low concerning the extrusion equipment of producing broad-amplitude film for frequent replacing production kind.
4, have only a ￠ 250 extruder feed, can't satisfy the requirement of high-throughput.
(3) utility model content:
At the weak point of above-mentioned extrusion equipment, the purpose of this utility model has provided a kind of wide rubber sheet extrusion calendaring unit that increases substantially output on former basis; Another purpose of the present utility model provides a kind of wide rubber sheet extrusion calendaring unit that can adapt to the production of different size broad-amplitude film expediently.
Can realize the wide rubber sheet extrusion calendaring unit of above-mentioned purpose, comprised calender and to the extrusion equipment of calender feed, different is: the extrude unit of described extrusion equipment for being made of extruder arranged side by side more than two or two, extrude sizing material by a combination head,, complex structure huge because of the size of single extruder head, processing and fabricating difficulty to solve, and use not convenient, the inferior problem of inefficiency aborning, and make its output increase substantially than originally.
Can will make up head according to the quantity of extruder and be separated into two or more, each extruder head corresponds respectively to the separate unit extruder, during installation each extruder head is constituted the combination head mutually side by side, and make its head exit on same vertical plane, connect by mixed flow device or materials flow separator between the adjacent head.
Mixed flow device or materials flow separator are connected the flow passage chamber intersection in the adjacent extruder head.
When two or more extruder heads use simultaneously, connect by the mixed flow device between the adjacent head.If the width of sizing material is extruded in control, can in the outermost flow passage chamber of combination head, the runner embedded block be set respectively, the distance between the runner embedded block of both sides has just determined to use two or more extruder heads to extrude the width of sizing material simultaneously.The kind of variable runner embedded block or size are to satisfy the production needs of different in width film.
When two or more extruder heads use simultaneously, if the sizing material width of extruding can't satisfy the smaller szie requirement, need use separately then that wherein separate unit extruder and head are produced, by materials flow separator connected between the adjacent extruder head this moment, place, flow passage chamber both sides at the separate unit extruder head is provided with the runner embedded block respectively, and the width between the separate unit extruder head runner embedded block has determined the sizing material width that this extruder head is extruded.The kind of variable runner embedded block or size are to satisfy the production needs of different in width film.
For making sizing material reach all even stable of flow velocity and flow, can the materials flow balancer be set in the flow passage chamber import department of every extruder head in the flow passage chamber outlet.
Advantage of the present utility model:
1, the utility model wide rubber sheet extrusion calendaring unit uses the shared combination head of a plurality of extruders, can increase substantially output on the basis of existing equipment, denumerable times of increase of the greatest width dimension of the film of being produced.
2, can connect by mixed flow device or materials flow separator between the single head in the combination head; The width of film can be decided by the quantity and the size of runner embedded block, to adapt to the production demand of different size format film.
3, the single extruder head in the combination head is simple in structure, easy to manufacture; In producing use, only need to change the runner embedded block, just can change institute's production film size, production efficiency height quickly.
4, the utility model wide rubber sheet extrusion calendaring unit has been realized the function that adopts the big goods of small device manufacturing and enhance productivity.
