Abstract
The utility model relates to an L-shaped extruding head which manufactures thin films with broad width by adopting an extrusion method, and is characterized in that the structure of the main body is integral. The previous L-shaped extruding head is two-half-piece type structure which is fastened to be one whole by a plurality of large-scale bolts. The middle part of an integral type head body (8) is provided with a U-shaped groove in which a flow passage die cavity (6) is positioned. The uniformity and the size accuracy of the extruding film can be controlled by regulating a mouth-shaped board adjusting bolt (1) and a damping plate adjusting bolt (2). A water circulation passage (7) is used for controlling the processing temperature of the whole head.
Description
Technical field
The utility model relates to a kind of L type extruder head that adopts the thin film of extrusion molding production wide cut, is characterized in that agent structure is a monoblock type.
Background technology
At present, known L type extruder head is two halves formula structure, and nearly 1 ton of per half weight is tightened to one with the large-scale bolt of about 30 M36 with two halves.When carrying out the gel resin operation, all bolts must be unloaded, open the two halves handpiece body again, cause labour intensity very big, it is oversize to expend time in, but also the auxiliary of crane gear must be arranged.
Summary of the invention
The purpose of this utility model is the deficiency at above-mentioned two halves formula L type extruder head, designs a kind of novel L type extruder head of monolithic construction, and its operation is easily saved time, and also need not crane gear.
The purpose of this utility model is achieved in that to be separated the core bit stream road die cavity of former two halves formula L type extruder head from handpiece body, it is the cone die cavity of a side openings, is provided with damping sheet at opening.When sizing material is stressed upon in the die cavity when flowing, rationally regulate damping sheet and die panel can extrude thickness evenly, the thin film of wide cut of dimensionally stable.In order to resist powerful tension, former two halves formula handpiece body is made overall structure, thereby saved all fastening bolts from the runner die cavity.
The advantage of integral L type film extruder head is conspicuous: at first it has avoided the heavy operation of many fastening bolts of dismounting, saves the hoisting operation of folding two halves handpiece body, thereby reduces labor intensity, and shortens non-cutting time.Secondly the rigidity of integral L type film extruder head is very strong, is out of shape minimum.The water circulation channel connection and reasonable arrangement, temperature-responsive is rapid, and therefore the temperature-controlled precision height has improved the dimensional accuracy of extruding film greatly.In addition integral L type film extruder head than two halves formula designs simplification high-leveled and difficult processing technology, saved fastening bolt, manufacturing cost is reduced significantly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified
Fig. 1 is an appearance assumption diagram of the present utility model
Fig. 2 is an A-A cutaway view among Fig. 1
Among the figure: 1 die panel is regulated bolt 2 damping sheets and is regulated bolt 3 spiral clamping devices 4 die panels 5 damping sheets 6 runner die cavitys 7 water circulation channels 8 handpiece bodies
The specific embodiment
As shown in the figure, handpiece body (8) is designed to integrated mechanism, and its left end is connected with Rubber Extruder, and bearing support is arranged at the bottom.Though it is very heavy, once mounting need not dismounting.Handpiece body (8) is basic components, adopts high-quality structural steel to make, and it vertically can be a joint or number joint.The inside of handpiece body (8) is provided with water circulation channel (7), in order to control the temperature of whole head.The top of handpiece body (8) has die panel to regulate bolt (1), and the bottom has damping sheet to regulate bolt (2), regulates these two groups of bolts and can make the isostasy of extruding film, dimensionally stable.The middle part of handpiece body (8) is a U moldeed depth groove, and runner die cavity (6) is positioned at wherein, and its outside has die panel (4) to compress, and right-hand member has spiral clamping device (3) spacing.Sizing material can produce the powerful tension of above-below direction to runner die cavity (6) when film was extruded, and the monolithic construction of handpiece body (8) can be resisted.The sprue of runner die cavity (6) is a cone, and a side has gum outlet, it adopts high-quality structural steel to forge and forms, and the inwall hard chrome plating of runner is to reduce the mobile resistance of sizing material and to increase the service life.When needing gel resin runner die cavity (6) side direction from the U type groove of handpiece body (8) ejected and get final product.
Claims (3)
1. integral L type film extruder head, it is characterized in that: handpiece body (8) is an integral body.Its middle part is provided with U type groove, and runner die cavity (6) is positioned at wherein.
2. integral L type film extruder head according to claim 1, it is characterized in that: runner die cavity (6) is the cone cavity of a side opening, be provided with die panel (4) and damping sheet (5) at opening part, but and the through port template is regulated bolt (1) and damping sheet adjusting bolt (2) is regulated.
3. integral L type film extruder head according to claim 1 is characterized in that: the technological temperature that is provided with the whole head of water circulation channel (7) control in the handpiece body (8).
