Description
Technical field
The utility model belongs to the technical field of plastics membrane production equipment, and in particular to a kind of multi-layer co-extruded plastics of upward type
Film blowing device.
Background technology
Plastic foil can be set using the multi-layer co-extruded plastics film blowing device production of upward type, the multi-layer co-extruded plastics blown film of upward type
Standby to be provided with multiple stage extruder and an extrusion die, each extruder is connected respectively to extrusion die, and extrusion die is provided with annulus
Shape extrusion, extrusion die top is provided with the cooling vane of annular, and cooling vane top is provided with herringbone clamping plate, herringbone clevis
Plate top is provided with traction nip rolls, and the downstream for drawing nip rolls is provided with Scroll；Cooling vane is connected with air compressor.
During production, the resin material of high-temperature fusion is pressed into extrusion die by each extruder, after extruded die head extrusion, Jing
The cooling of supercooling vane and form the compound film bubble of annular, can be divided into inside and outside multilayer in the microstructure of compound film bubble
（Each layer of material corresponds to come from an extruder respectively）, the film bubble of annular becomes double-deck thin after collapser flattening
Film, is then led away by traction nip rolls, until last winding.
Because the cooling procedure Air Quantity Required of annular film bubble is larger, thus the volume of air compressor is generally larger, weight
Amount is heavier.Further, since, it is the extrusion pressure of each layer of material, extruded velocity, extrusion temperature, the air pressure of cooling vane, cold
But all many technological parameters such as air mass flow of vane, need the control synthesized and coordinated, therefore upward type is multilayer coextruded
Material film blowing device is designed with electric control box, and the volume and weight of electric control box is larger.
On the other hand, due to reasons such as Machine Design, frame for movement, machinings, extrude from the annular of blow moulding equipment
The cylindric film bubble each point thickness of mouth extrusion has difference in fact, and for example the bubble thickness in the mouth correspondence orientation that shoots material can be substantially
It is partially thick, and this thickness deviation belongs to Systematic Errors, if the point in the i.e. a certain orientation of film bubble is partially thick, follow-up film out
Bubble continues partially thick film after institute's conventional manner described above winding, if untreated, thick point in the orientation（Or title salient point）Meeting
Gradually add up superposition in the same position of coiled material, make the film roll thickness after winding seriously uneven, produce quick-fried muscle phenomenon, wind matter
Amount is poor.
Have following two to overcome disadvantages mentioned above, traditional settling mode：The first settling mode be each extruder,
Herringbone clamping plate and traction nip rolls are all maintained static, but extrusion die does not stop rotation, it is meant that annular extrusion does not stop rotation,
So distributing position of the thick point of film on axial direction on coiled material just presents distributed wave state, but this mode is present substantially not
Foot：Because the extrusion pressure of fused materials is big, therefore the swivel seal of extrusion die is extremely difficult, and Jing often produces material leakage,
Thus first kind of way is seldom adopted；
Second settling mode is using mechanical rotary tractor：Extruder and die head are maintained static, and Scroll is fixed
It is motionless, but traction nip rolls and herringbone clamping plate is rotated around head central axis, that is, nip rolls is drawn relative to extrusion die（Film
Bubble）Rotation, distributing position of the thick point of such film on axial direction on coiled material just presents distributed wave state, along the axial direction of coiled material
Spread out, thus preferably solve thick point（Or title salient point）Systematic Errors and the winding accumulation problem brought, make film
Salient point be uniformly distributed in the axial direction of coiled material, will not accumulate in same position, it is to avoid quick-fried muscle, reach the smooth purpose of winding.
Rotary tractor is occurred in many Chinese patents, such as CN201410774285.4, CN201320366814.8,
The Chinese patents such as CN200920062191.9.
Although however, above-mentioned mechanical rotary tractor solves well quick-fried muscle phenomenon, but also paying very big generation
Valency：After the rotation of head central axis, the direct of travel of film must be deflected therewith for traction nip rolls and herringbone clamping plate, therefore
In follow-up travel path, it is necessary to reverse back the direct of travel of film to come, to make fixed Scroll normal
Winding.Therefore, the complicated in mechanical structure of rotary tractor, and film is run when rotation traction traction mechanism, film surface
Relative with each moveable idler surface generation can slide, twist, film surface can produce sliding friction, film with moveable idler surface
Easily surprisingly pulled.
Utility model content
The purpose of this utility model is to overcome disadvantages mentioned above and provide a kind of upward type multi-layer co-extruded plastics film blowing device,
After the film bubble winding that it is produced, the salient point of film is axially evenly distributed along coiled material, it is to avoid quick-fried muscle phenomenon, and is avoided that in winding
Process is pulled by force, twists film, it is to avoid sprain film.
Its purpose can be realized by below scheme：A kind of multi-layer co-extruded plastics film blowing device of upward type, includes multiple stage and squeezes
Go out machine and an extrusion die, the extrusion of each extruder is connected respectively to extrusion die, and extrusion die is provided with annular and squeezes
Outlet, extrusion die top is provided with the cooling vane of annular, and cooling vane top is provided with the fixed herringbone clevis in position
