Abstract
The utility model discloses a seven-layer coextrusion high-barrier film blow molding machine nose, which comprises a mandrel, a runner disc, a joint disc, a top disc, an inner die, an outer die, screws and copper rods. A dish-shaped sheet design is adopted for a plane overlapping nose so as to ensure seven overlapping layers are reached, each layer is fully distributed with U-shaped runners as designed, a structure for dividing materials into halves and combining materials by pairs continuously ensures that the materials are more sufficiently heated, and a computer is in centralized control of a detection system so as to automatically adjust the temperature and ensure that materials are not fluidized due to overhigh temperature of a nose, therefore the flowability of the materials are effectively improved; the materials are fed in from sides, thus the materials are uniformly distributed in the nose with uniform heating and the extruded film products have consistent density; and moreover, the runners inside the nose are provided with fewer inflection points, therefore no dead angle exists.
Description
Technical field
The utility model relates to a kind of extrusion-blown modling machine head of making plural layers, is 7 layers of co-extrusion superposing type of a kind of use double spiral plane inflation film manufacturing machine head.
Background technology
Along with the development and the progress of society, people's quality of life is constantly improved, and is also more and more higher to various plastic film performance demands.In the past three layers, the head of five-layer co-squeezing blowing unit also rest on inclined flow passage formula head, and shortcoming is: the head discharging has the dead angle, does not have the melt pressure sensor, results in blockage, and is difficult to cleaning; The evenness of discharge degree is poor, uneven distribution; The pressed density of head is low, and product tensile strength and the elongation at break produced are low; The product soffening is poor, and cloud and mist, striped, water wave phenomenon are arranged; Yield poorly, the air cooling system refrigerating speed is slow, and the cooling of film bubble is slow.
The utility model content
The utility model provides a kind of seven-layer co-extrusion high-isolation film blowing machine head at the problems referred to above, and its purpose is, being primarily aimed at prior art provides a kind of and can produce the intensity height, and the number of plies is many, the blow moulding machine head of the seven-layer co-extrusion film of good evenness.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: a kind of seven co-extrusion high-isolation film blowing machine heads are provided.This head, include core 1, runner dish 2, terminal pad 3, take over a business 9, internal orifice mould 10, collar extension mould 13 and screw 5,7,8,11,12,14 and copper rod 4 form, runner dish 2, terminal pad 3 and take over a business 9 be the stack shape be placed on the core 1, wherein runner dish 2 and terminal pad 3 every parts are 7 parts, taking over a business 9 is 1 part, and with screw 7,8 that its series connection bolt is tight.
According to seven-layer co-extrusion high-isolation film blowing machine head one optimal technical scheme described in the utility model: described flow channel dish 2 inner flow passages are distributed in the same plane, and its structure is 2
nType structure, i.e. one-to-two, two minutes four, four minutes eight structures.
According to seven-layer co-extrusion high-isolation film blowing machine head one optimal technical scheme described in the utility model: between described runner dish 2 and the terminal pad 3 insulating layer is arranged.
The utility model beneficial effect is: three layers different from the past, five-layer co-squeezing blowing unit inclined flow passage formula head, but Composite Double helical planes stack head; The head flex point is few, does not have the dead angle, and U type pipeline is dispersed throughout runner dish 2,2
nThe type structure helps to cause the discharging good evenness, and fineness is good, and thin and thick is even; Head pressed density height, product tensile strength of producing and elongation at break height; Because each layer is temperature control separately all, and raw material is better plastified, be unlikely to make and be close to two-layer temperature unanimity by the heat conduction; Soffening is good, and defect ware reduces significantly.

The specific embodiment
Utilize the course of work of the present utility model: thermoplastic is heated to molten condition through the pulverizing of hopper by extruder, enter in the utility model head, and by every layer of charging aperture (totally seven layers), in double spiral plane superposing type head, 2 of runner dish 2
nType structure runner is extruded with the form of seven layers of compound fluid shape, adjusts the goods minimal thickness by internal orifice mould 10 and the collar extension mould 13 that settle the head upper end, with the vane cooling, forms film.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and utility model design thereof, all should be encompassed within the protection domain of the present utility model.
