Embodiment 1:
Fig. 1 is a kind of decomposition texture schematic diagram of the screen system of embodiment of the utility model, and Fig. 2 is the utility model
A kind of work flow diagram of the laminating machine of embodiment.Laminating machine screen system provided by the utility model, as shown in Figure 1, including
At least three layers of strainer filtering layer 1,1 surface of strainer filtering layer are equipped with filter hole 2, and melted material can be from the one of strainer filtering layer 1
Side reaches the other side of strainer filtering layer 1 by filter hole 2, extends inwards from the direction that melted material enters, strainer filtering layer 1
On 2 data of filter hole gradually increase, size is gradually reduced.The specific implementation steps are as follows:
(1) melted material enters screen system, by the strainer filtering layer 1 nearest from melted material inlet port, be located at into
2 aperture of filter hole on the strainer filtering layer 1 of entrance is maximum, and mesh number is minimum；
(2) then melted material passes through next layer of strainer filtering layer 1, strainer filtering layer 1 of next layer with respect to inlet port, mistake
2 aperture of filter opening is slightly smaller, and number is slightly more；
(3) successively backward, 1 filter hole of strainer filtering layer, 2 aperture that melted material passes through is gradually reduced, and number gradually increases
It is more.
Each layer of strainer filtering layer 1 can be made to obstruct the different impurity of size using this kind of laminating machine screen system, thus
The impurity for keeping size different can be filtered, and be overcome in the single caused melted material of existing filter screen size containing miscellaneous
Matter to make the film surface to be formed have crystal point or foreign matter, while various sizes of impurity is filtered, and squeezes out melted material
It cannot be with the fully effective defect being bonded of paper.
For example, 1 each layer of shapes and sizes of strainer filtering layer are all the same, 60 mesh wherein are distributed on first layer strainer filtering layer 1
Filter hole 2 is distributed 80 mesh filter hole 2 on second layer strainer filtering layer 1, and third layer strainer filtering layer 1 is distributed 100 mesh filter hole 2,
4th layer of strainer filtering layer 1 is distributed 120 mesh filter hole 2, and the first layer screen support layer 3 adjacent with strainer filtering layer 1 is then
80 mesh filter hole 2 are distributed, second layer strainer supporting course 3 is distributed 60 mesh filter hole 2.
As the optional embodiment of the present embodiment, as shown in Figure 1, after melted material enters screen system in order to prevent
Pressure causes greatly very much strainer that skew back occurs, and installs screen support layer 3 in the outflow end of melted material, screen support layer 3 is melting
When material is excessive to 1 pressure of strainer filtering layer, strainer filtering layer 1 can be supported.
As the optional embodiment of the present embodiment, as shown in Figure 1, different in the melted material through filter screen filtration layer 1
The impurity of size is different degrees of to be filtered, therefore 2 aperture of filter hole of screen support layer 3 should be sufficiently large, main mesh
Be not filtration and supporting role, the aperture of this kind of filter hole 2 is greater than or equal to the filtering for being placed in strainer filtering layer 1
The aperture in hole 2.
As the optional embodiment of the present embodiment, as shown in Figure 1, since melted material passes through on strainer filtering layer 1
When filter hole 2 filters, it is generally concentrated at intermediate region, in order to reduce melted material to the pressure of 1 intermediate region of strainer filtering layer,
Therefore the number for being set to the filter hole 2 at single 1 center of strainer filtering layer is more than the number for being set to same 1 edge of strainer filtering layer
Mesh.
As the optional embodiment of the present embodiment, as shown in Figure 1, when the aperture of heating system is greater than the filter of screen system
When the size of net filtration layer 1, filter hole 2 is then uniformly distributed on strainer filtering layer 1.
As the optional embodiment of the present embodiment, as shown in Figure 1, in order to improve strainer filtering layer 1 in screen system
Filter efficiency, each strainer filtering layer 1 is parallel to each other, and the size for being placed in the strainer filtering layer 1 of melted material outlet end is greater than
It is placed in the size of melted material input end.
As the optional embodiment of the present embodiment, as shown in Figure 1, in order to preferably provide the filtering of strainer filtering layer 1
Efficiency, by filter hole 2 be provided in round and/or ellipse, compared with other shapes of filter hole 2, the mistake of round or ellipse
2 edge transition of filter opening is round and smooth, without angle, melted material can quickly by filter hole 2, and because there is no angle, filtering
The edge in hole 2 will not remain melted material.
As the optional embodiment of the present embodiment, as shown in Figure 1, strainer filtering layer 1 is set as metal material, with other
Material is compared, and the heat resistance of metal material is more preferable, and more permanent using the time, is specifically 304# stainless steel material.
As the optional embodiment of the present embodiment, as shown in Figure 1, according to the group of the raw material plastic grain of melted material
At difference, the mesh number of the number of strainer filtering layer 1 and each strainer filtering layer 1 also can be corresponding variant, therefore, single to filter
Net filtration layer 1 is mobilizable to be installed in screen system, particularly strainer filtering layer 1 and the strainer for being placed in screen system simultaneously
Mounting groove 4 is flexibly connected, and is snapped connection wherein being flexibly connected can be, as long as other connection types can make strainer filtering layer 1
It is detachable with strainer mounting groove 4, it is within the protection scope of the utility model.The both ends clamping of strainer filtering layer 1 when use
In the groove of strainer mounting groove 4, strainer filtering layer 1 is taken out out of strainer mounting groove 4 groove when not used, to adapt to difference
Melted material.
Embodiment 2:
The utility model additionally provides a kind of laminating machine, as shown in Fig. 2, further including in addition to including laminating machine screen system
Heating system, feeding mechanism and mold, heating system one end are connect with feeding mechanism, the heating system other end and screen system
Connection, plastic grain flow into heating system from feeding mechanism, and by the heating of heating system, plastic grain melts, and form melting
Material, then melted material enters the screen system connecting with heating system, filters through filter net system, is passing through melted material
Circulation, reaches mold, melted material to form leaching membrane paper with merging for paper.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with the power
Subject to the protection scope that benefit requires.
