Abstract
The utility model discloses a quick net changing device of an extruder. The quick net changing device consists of a cavity, a filter net board, sealing rings and a hydraulic assembly, wherein the sealing rings are respectively arranged in front and back of mesh holes of the filter net board; the quick net changing device of the extruder is characterized in that one of the sealing rings is an adjustable sealing ring, wherein the sealing ring is in threaded connection with the cavity; a plurality of adjusting slots are formed in the outer wall; the sealing ring is further arranged between a cavity opening and the adjustable sealing ring, one tenon-shaped end of the sealing ring is internally arranged in the adjustable sealing ring. If abrasion appears, the sealing can be furthermore realized only by rotation and adjustment. A sealing structure is convenient to adjust and operate, high in production efficiency and capable of lowering the consumption of the sealing rings.
Description
Technical field
The utility model relates to a kind of extruder quick net exchanging device.
Background technology
Net-changing device is a kind of corollary equipment of producing plastic plate, thin film extruding machine that is exclusively used in, and filters for the melt that extruder is flowed out.Existing net-changing device is hydraulic control, is comprised of cavity, screen pack, hydraulic package and seal, and two seals directly are fixed on the screen pack front and back position.This structure makes seal easy to wear, so that replacement frequency is high, increases cost.
The utility model content
The purpose of this utility model is to provide a kind of net-changing device, and its sealing device can reduce wear, and reduces the replacing number of times of seal.
For achieving the above object, the utility model provides following technical scheme: a kind of extruder quick net exchanging device, by cavity, screen pack, sealing ring and hydraulic package, formed, the front and back of screen pack mesh are provided with sealing ring, one of them sealing ring is the adjustable dense seal ring, the sealing ring is threaded with cavity, on outer wall, has a plurality of regulating tanks; Between cavity hatch and adjusting sealing ring, also be provided with a sealing ring, its tenon shape one end is built in to be regulated in sealing ring.
Adopt said structure; can realize not stop hydraulic quick net exchanging device; by regulating sealing ring, realize the sealing adjusting of the filter mesh of web plate, regulating tank adapts to the insertion adjustment means, and the tenon V-shaped ring at its sealing position can prevent that fluid from entering the infiltration threaded connection place.As wearing and tearing appear, only need rotation to regulate and can realize further sealing.Sealing structure adjustment operation is convenient, production efficiency is high, and can reduce the consumption of sealing ring.

The specific embodiment
As shown in Figure 1,2 and 3, the utility model provides a kind of extrusion machine fused mass quick net-changing device, by cavity 1, screen pack 2, sealing ring and hydraulic package 3, formed, cavity 1 is integral type, on have the slot 11 of perforation, front and back are provided with the runner through hole 12 of perforation, the upper end of screen pack 2 is fixedly connected with hydraulic package 3, the slot 11 of cavity 1 is passed in lower end, screen pack 2 is provided with two filter mesh 21, in mesh, be provided with screen pack, any one mesh 21 respective chamber runner through hole 12, so that melt passes through.Sealing ring comprises three, respectively to regulate sealing ring 4, tenon V-shaped ring 5 and conventional seals ring 6, regulating sealing ring 4 is threaded with cavity 1, be arranged on charging aperture one end, on outer wall, have a plurality of regulating tanks 41, this regulating tank 41 adapts to adjustment means, just makes adjustment means be positioned sealing ring 4, is beneficial to left rotation and right rotation; Between cavity hatch and adjusting sealing ring 4, also be provided with a tenon V-shaped ring 5, its tenon shape one end is built in to be regulated in sealing ring 4, penetrates in the thread gaps of regulating sealing ring 4 and cavity 1 to prevent melt.In above-mentioned cavity 1, also be built-in with heating rod (not looking in figure), and external terminal box, to keep the temperature of Melt.
As shown in Fig. 4,5 and 6, the utility model provides another kind of extrusion machine fused mass quick net-changing device, by cavity 1 ', screen pack 2 ', sealing ring and hydraulic package 3 ', formed, cavity 1 ' is split type, comprises feed end cavity 11 ' and discharge end cavity 12 ', is fixedly connected with by screw 7 ', on have the slot 13 ' of perforation, front and back are provided with the runner through hole 14 ' of perforation, on cavity, are built-in with heating rod 8 ', and are equipped with terminal box 9 ' outward; On the cavity 11 ' of two splits, 12 ', be respectively equipped with the storage tank of sealing ring, the upper end of screen pack 2 ' is fixedly connected with hydraulic package 3 ', the slot 13 ' of cavity is passed in lower end, screen pack 2 ' is provided with two filter mesh 21 ', and be provided with screen pack, any one mesh 21 ' respective chamber runner through hole 14 ', so that melt passes through.Sealing ring comprises three, respectively to regulate sealing ring 4 ', 2 conventional seals rings 5 ', 6 ', regulate on sealing ring 4 ' outer wall and have a plurality of regulating tanks 41 ', and be threaded with one of them sealing ring 5 ', sealing ring 5 ' is contained in the storage tank of feed end cavity, for preventing its displacement, with pin 10 ', that itself and feed end cavity 11 ' is fixing; In discharge end cavity storage tank, be provided with another sealing ring 6 '.
During use, by the hydraulic cylinder outputting power, make screen pack move up and down location, two filter mesh can be realized online filter screen replacement.As the wearing and tearing of sealing ring or poorly sealed appear, the available dedicated instrument, be insinuated in cavity, blocks the adjusting sealing ring, rotates it and do and move forward and backward, and realizes the sealing of screen pack.
