Description
Technical field
The utility model belongs to thermoplastic materials shaping field, relates in particular to a kind of plastic extruder compressing tablet building mortion.
Background technology
Plastic sheet, plate are the conventional goods of being produced by the flat head of narrow slit, and demand is larger, and serviceability requires more and more higher.The key component of plastic sheet, sheet material forming is compressing tablet building mortion.Melt is under the effect of certain pressure, by machine head port mould formation and sheet, the similar parison of sheet material section configuration.Traditional plastic extruder compressing tablet building mortion, often melt depanning speed is difficult for control, and plastic sheet, plate thickness regulate difficulty large, change the die lip length that expends time in.
Utility model content
For the problems referred to above that will solve, the utility model provides a kind of plastic extruder compressing tablet building mortion, guarantees the uniformity of parison thickness, conveniently adjusted plastic sheet, plate thickness, and ensure that mouthful die clearance and melt depanning speed keep uniformity.
The technical solution of the utility model: a kind of plastic extruder compressing tablet building mortion, it is characterized in that comprising flexible upper die lip, temperature-sensitive telescopic adjustment nut, choked flow row adjuster, head body, melt-flow is threaded a pipe, grooving, replaceable lower die lip, described flexible upper die lip and described replaceable lower die lip are symmetricly set on the upper and lower of described head body front end, between described flexible upper die lip and described replaceable lower die lip, cavity forms described grooving, described temperature-sensitive telescopic adjustment nut be arranged on described flexible upper die lip oblique upper and contact-making surface parallel, described choked flow row adjuster is arranged on described temperature-sensitive telescopic adjustment rear nut, described the melt-flow multiple and parallel determining deviation of having threaded a pipe is distributed in described head body middle level, multiple described melt-flow are threaded a pipe and are communicated with described grooving, the axial described grooving length direction that described melt-flow is threaded a pipe is vertical.
Also comprise measuring pump and filter, described melt-flow is threaded a pipe and is connected with measuring pump, described filter be located at that described melt-flow is threaded a pipe and described measuring pump between.
Described temperature-sensitive telescopic adjustment nut adopts ceramic clamping piece structure.
Described choked flow row adjuster adopts indented form structure, and that the choked flow of described choked flow row adjuster is shaped as is trapezoidal, triangular form or parallelogram.
Described replaceable lower die lip is connected with described head body by nut, and described replaceable lower die lip is short shaped segment die lip mold insert, moderate type shape section die lip mold insert or long shaped segment die lip mold insert.
The beneficial effects of the utility model: can arrange adjuster by choked flow and effectively control along fabric width direction flow velocity, can regulate by temperature-sensitive telescopic adjustment nut the spacing of flexible upper die lip and replaceable lower die lip, and then the thickness of adjustment sheet film meets different product needed.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure chart in this practical cross section.
In figure, 1, flexible upper die lip, 2, temperature-sensitive telescopic adjustment nut, 3, choked flow row adjuster, 4, head body, 5, melt-flow threads a pipe, 6, grooving, 7, replaceable lower die lip, 8, measuring pump, 9, filter.
Detailed description of the invention
Below in conjunction with attached Fig. 1 and 2, a kind of detailed description of the invention of the present utility model is explained.
The utility model relates to a kind of plastic extruder compressing tablet building mortion, comprise flexible upper die lip 1, temperature-sensitive telescopic adjustment nut 2, choked flow row adjuster 3, head body 4, melt-flow threads a pipe 5, grooving 6, replaceable lower die lip 7, flexible upper die lip 1 and replaceable lower die lip 7 are symmetricly set on these 4 body front ends of head, cavity forming shaped groove 6 between flexible upper die lip 1 and replaceable lower die lip 7, temperature-sensitive telescopic adjustment nut 2 adopts ceramic clamping piece structure, temperature-sensitive telescopic adjustment nut 2 is arranged on oblique 1 top of flexible upper die lip, can regulate by temperature-sensitive telescopic adjustment nut 2 spacing of flexible upper die lip 1 and replaceable lower die lip 2, and then the thickness of adjustment sheet film meets different product needed, choked flow row adjuster 3 is arranged on temperature-sensitive telescopic adjustment nut 2 rears, can effectively control along the flow velocity of each point of fabric width direction, the melt-flow that multiple parallel determining deviations distribute is threaded a pipe and 5 is arranged on head body 4 middle levels and is communicated with grooving 6, thread a pipe 5 axial grooving 6 length directions of melt-flow are vertical, device also comprises measuring pump 8 and filter 9, melt-flow is threaded a pipe and 8 is connected with measuring pump 7, filter 9 be located at melt-flow thread a pipe 5 and measuring pump 8 between, prevent that impurity from entering melt-flow and threading a pipe 5, affect product quality.
Choked flow row adjuster 3 adopts indented form structure, and that the choked flow of choked flow row adjuster 3 is shaped as is trapezoidal, triangular form or parallelogram, is conducive to the row of adjusting and arranges, and has expanded operating space, and choked flow face shape is also simple simultaneously, without dead angle.Replaceable lower die lip 7 is connected with head body 4 by nut, replaceable lower die lip 7 is short shaped segment die lip mold insert, moderate type shape section die lip mold insert or long shaped segment die lip mold insert, in the time changing sheet, plate thickness, change sotck thinkness, therefrom select suitable mold insert, the lower die lip of changing head, does not need to change whole lower die lip part or whole head, and the replacing time can shorten widely.
Above an example of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
