Abstract
The utility model discloses a kind of Dan Pou mechanism of extrusion-blown modling monolithic ultrathin membrane, frame is provided with two blocks of symmetrical collapsers (4), the steel rider (2) and rubber roll (3) that can rotate are installed directly over described collapser; Install in collapser side and cut open knife assembly (9) with connecting rod (6), the described knife assembly that cuts open is fixedly mounted on collapser by connecting rod, described connecting rod is connected with knife rest pillar (7), knife rest pillar is provided with tool rest bracket (12), described tool rest bracket is provided with and cuts open cutter (8).Beneficial effect: this mechanism, by cuing open knife assembly and be arranged on the side of collapser, through the increase of frame upper shed radian, can form the most large stretch of single thin film.Especially, on same unit, the width of film can be made to be original twice.This device improves original mode of production, adds the type of product, improves the production capacity of equipment, to answer needed for farming.
Description
Technical field
The utility model relates to a kind of Dan Pou mechanism of ultrathin membrane, and specifically a kind of Dan Pou mechanism of extrusion-blown modling monolithic ultrathin membrane, belongs to the production equipment field of ultrathin film.
Background technology
Generally speaking, the special ultrathin film of agricultural covered ground is with LDPE and LLDPE resin for raw material, by the method volume production of extrusion-blown modling.For the ease of covered ground, film mostly is monolithic and batches pattern; Simultaneously again due to the thinner thickness of film, the film that extrusion-blown modling is produced is tubular structure, when producing film, needing utilization to cut open cutter and the film of tubular structure is become monolithic thin film.Cut open cutter and have polytype, have double-pole to cut open two volumes and cut open cutter, have three cuttves to cut open four volumes and cut open cutter etc.In existing production machine, cut open before cutter is generally installed on traction and lower traction, and be close to lower traction one end.This kind cuts open cutting die formula to be caused, on same equipment, can only producing undersized goods, thus causing equipment to have limitation.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of Dan Pou mechanism of extrusion-blown modling monolithic ultrathin membrane, on same unit, only uses one cuing open cutter, the width of ultrathin membrane product can be made to become original maximum sized twice, can the production capacity of expansion equipment.
For achieving the above object, the technical solution adopted in the utility model is: a kind of Dan Pou mechanism of extrusion-blown modling monolithic ultrathin membrane: two blocks of symmetrical collapsers are installed in frame, directly over described collapser, the steel rider that can rotate and rubber roll are installed; Install in collapser side and cut open knife assembly with connecting rod, described in cut open knife assembly and be fixedly mounted on collapser by connecting rod, described connecting rod is connected with knife rest pillar, and knife rest pillar is provided with tool rest bracket, described tool rest bracket is provided with and cuts open cutter.
Further, described tool rest bracket is provided with the knife rest adjustment screw that can regulate knife rest angle.
Further, described tool rest bracket is provided with can adjust described in cut open cutter cut open cutter adjustment screw.
Further, described steel rider and rubber roll are all fixed by screws in described frame.
The beneficial effects of the utility model are: this mechanism, by cuing open knife assembly and be arranged on the side of collapser, through the increase of frame upper shed radian, can form the most large stretch of single thin film.Especially, on same unit, the width of film can be made to be original twice.This device improves original mode of production, adds the type of product, improves the production capacity of equipment, to answer needed for farming.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3: the Dan Pou mechanism of a kind of extrusion-blown modling three sections of ultrathin membranes, frame is provided with two symmetrical collapsers 4, directly over collapser 4, both sides are provided with the steel rider 2 and rubber roll 3 that can rotate, and described steel rider 2 and rubber roll 3 are connected by screw and are arranged in frame.Be provided with and cut open knife assembly 9 below steel rider 2 and on the left of collapser 4, described in cut open knife assembly 9 and connected by the connecting rod 6 be fixed on collapser 4.Connecting rod 6 is connected with knife rest pillar 7, and knife rest pillar 7 is provided with tool rest bracket 12, tool rest bracket 12 is provided with and cuts open cutter 8.Tool rest bracket 12 is provided with the knife rest adjustment screw 11 that can adjust knife rest angle, knife rest 12 is provided with can adjust cut open cutter 8 cut open cutter adjustment screw 10.
Specific works process: first, is added polyvinyl resin and auxiliary agent by the hopper of extruder, under fusion plastification in an extruder, becomes homogeneous melt, and melt arrives annulus system discharging opening through blown-film die, can extrude circular cylinder film continuously in discharge outlet; Secondly, cross-head is extruded continuously and continuous coo1ing sizing under having obtained the plastics molten condition of preliminary configuration and size, thus its shape and size are fixed up; Then the film bubble 5 after sizing is pulled roller and upwards draws with constant speed, wherein, carry-over pinch rolls comprise steel rider 2 and rubber roll 3, through collapser 4, the film bubble 5 after shaping is slowly planished, and through processing and the process of the cutter holder assembly 9 being arranged on collapser 4, enter into the roll gap between steel rider 2 and rubber roll 3, and compacted; Finally, the film after compression can become continuous print double-layer blowing film 1, and is admitted to devices for taking-up.
