Background technology
Existing inflation film manufacturing machine species is a lot, but often show that die wall thickness ununiformity is even, material temperature is unstable, discharge have some setbacks,
The low problem of efficiency, in particular for the higher edible mushroom bag industry of quality requirement, because culture medium of edible fungus is to bacterium bag bag
Requirement more and more higher, and if the thickness equal-specification of bacterium bag bag uneven will directly affect the quality of bacterium bag (rod), final shadow
The output value of edible mushroom is rung, accordingly, it would be desirable to which a kind of precision higher die head of film blowing machine meets above-mentioned requirements.
Utility model content
In order to solve the above technical problems, the purpose of this utility model, which is to provide one kind, can guarantee that the technical indicators such as blown film thickness
High-precision die head, concrete technical scheme is as follows：
A kind of die head of film blowing machine structure, including overcoat, the die orifice on overcoat top and the feed end of overcoat bottom, the overcoat
Inside sets and conveyor screw is set in circular cone through hole, the circular cone through hole, and the conveyor screw is also in pyramid type；The conveyor screw it is straight
The larger one end in footpath is fixed on feed end, and the less one end of diameter is fixed with core rod；A plurality of helicla flute, institute are set on conveyor screw
Helicla flute is stated to connect with charging aperture；The depth of the helicla flute is from large to small；The footpath of the circular cone through hole of the conveyor screw and overcoat
Change from small to big to gap；The core rod is arranged in die orifice, and the core rod includes setting in conus portion and cylindrical portion, the die orifice
The cavity of corresponding shape；The radial clearance of the conus portion of the core rod and the circular cone cavity of die orifice is from large to small；The mould
The radial clearance of the cylindrical portion of core and the cylinder cavity of die orifice is constant.
The helicla flute is more than the circle of conveyor screw two.
The cylindrical portion of the core rod and the length of the cylinder groove of die orifice are more than 40mm.
The utility model has the advantages that：
1st, the setting of conical spiral ensure that the radial clearance with outer inner room is changed from small to big；The depth of the helicla flute by
Diminish greatly (depth is numerical value, is described using from large to small)；Such set make it that resin flowing is more steady, and film bubble is put down
Whole, thin and thick is uniform, and tolerance value is small；2. the radial clearance of the conus portion of core rod and the circular cone cavity of die orifice is from large to small, blown film
During can guarantee that pressure gradually increases；
3rd, the outer ring helicla flute of conveyor screw is enclosed around body two, and more uniform, effective integration is blended；
4th, the cylindrical portion arm's length standard of core rod is highly 35mm, and the utility model is more than 40mm, improves resin after lengthening
Flowing velocity is more steady, uniform, is conducive to film mouthful uniform discharge.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is illustrated below in conjunction with the accompanying drawings, as shown in figure 1, the utility model is included on overcoat 2, overcoat 2
The die orifice 3 in portion and the feed end 12 of overcoat bottom, the inside of overcoat 2, which is set in circular cone through hole 6, the circular cone through hole 6, to be set
Conveyor screw 1, the conveyor screw 1 is also in pyramid type；One end being relatively large in diameter of the conveyor screw 1 is fixed on feed end 12, directly
The less one end in footpath is threadably secured or conveyor screw 1 and the integrated structure of core rod 4 with core rod 4；Set a plurality of on conveyor screw 1
Helicla flute 5, the helicla flute 5 is connected with charging aperture 10；From large to small, the present embodiment is by 20mm to the depth of the helicla flute 5
To 0mm；The section of helicla flute 5 is in semicircle shape；The radial clearance of the conveyor screw 1 and the circular cone through hole of overcoat 2 is changed from small to big, this
Embodiment one side gap is by 0 to 20mm；The core rod 4 is arranged in die orifice 3, and the core rod 4 includes conus portion 13 and cylinder
The conical bores 9 and circular cylindrical cavity 11 of corresponding shape are set in portion 14, the die orifice；The conus portion 13 of the core rod with
From large to small, the present embodiment one side gap is by 20 to 0.5mm for the radial clearance of the circular cone cavity 9 of die orifice；The circle of the core rod
Post portion 14 and the radial clearance of the cylinder cavity 11 of die orifice are constant.
The helicla flute 5 is more than 1 liang of circle of conveyor screw.Quantity the present embodiment of helicla flute 5 is 3, may also be set to 4
It is individual, 5,6 and more, specifically can be according to produce reality depending on.
The length of the cylindrical portion 14 of the core rod and the cylinder cavity 11 of die orifice is more than 40mm.
It is that cylindric, core rod conus portion 13 and the radial clearance of the circular cone cavity 9 of die orifice are constant relative to conveyor screw
Situation comparative example, in the case where other situations are constant, the blown film precision of the present embodiment is many higher, data such as table 1
Table 1
From above-described embodiment and the data of comparative example, the utility model is far better than comparative example；
Under the data cases maintained like, only change the quantity of conveyor screw, comparative example is using helix around conveyor screw 1
Circle, then, it is seen that the even situation of became uneven, data such as table 2
Table 2
As seen from the above table, the number of turns of helix is uniformly worth on the thickness of product influences larger, certainly, if the circle of conveyor screw
Number is excessive, and such as number of turns is 3, and the uniform value of thickness does not improve, such as table 3
Table 3
As long as ensureing that the radial clearance of the conveyor screw 1 and the circular cone through hole of overcoat 2 is changed from small to big, such as unilateral gap is served as reasons
0 to 10-20mm；The core rod 4 is arranged in die orifice 3, and the core rod 4 is included in conus portion 13 and cylindrical portion 14, the die orifice
The conical bores 9 and circular cylindrical cavity 11 of corresponding shape are set；The conus portion 13 of the core rod and the circular cone die cavity of die orifice
From large to small, such as unilateral gap is by 20-30 to 0.5mm for the radial clearance of body 9；The cylindrical portion 14 of the core rod and the cylinder of die orifice
The radial clearance of cavity 11 is constant；It is superior to circular cone cavity 9 of the conveyor screw for cylindric, core rod conus portion 13 and die orifice
The constant situation of radial clearance comparative example.
