Description

A kind of improvement structure of make-up machine

Technical field:

The utility model relates to a kind of process units of composite plastic film.

Background technology:

Existing make-up machine is generally by several film introducing mechanisms, several film preheating mechanisms, the thermal composite machine structure, cooling body, the diaphragm composite structure, rolling-up mechanism forms, during work, several film introducing mechanisms import corresponding film preheating mechanism by multiple film and carry out preheating, then import the thermal composite machine structure to carry out heat fusing compound simultaneously, laminated film after compound imports cooling body and carries out cooling, cooling body carry out cooling in, stick diaphragm by the diaphragm composite structure toward compound film surface, complete cooled laminated film is by the rolling-up mechanism rolling, back segment at the thermal composite machine structure is provided with emboss, in order to also on higher laminated film, suppress decorative pattern in temperature.This kind of make-up machine, what adopt due to the live-roller of the running part in all mechanisms is all the metallic roll of surface finish or surface smoothing, determined by the physical property on metallic roll surface, the plastic sheeting by the warm-up mill guiding in compound stage of high temperature easily has the appearance sticked in the phenomenon on warm-up mill surface, the lighter makes plastic foil produce abnormal local elongation, and severe one can be torn plastic sheeting.

Summary of the invention:

Goal of the invention of the present utility model is to provide a kind of can prevent that plastic sheeting from sticking the improvement structure of the make-up machine that the phenomenon on the warm-up mill surface occurs.

The utility model is to realize like this, comprise several film introducing mechanisms, several film preheating mechanisms, the thermal composite machine structure, cooling body, the diaphragm composite structure, rolling-up mechanism, the film preheating mechanism comprises several preheat rolls that driven by power, lean against the pressure roller driven by pneumatic power on first preheat roll, the inner chamber of preheat roll imports the thermal medium of adding, the thermal composite machine structure comprises the large warm-up mill driven by power, be arranged on the heating mantles of large warm-up mill composite surface top, the several doff rolls that driven by power, large warm-up mill inner chamber, the doff roll inner chamber has all imported and has added thermal medium, cooling body comprises that several inner chambers import the large several chill rolls of diameter ratio temperature refining roller that the temperature driven by power of hot water refining roller arranged and driven by power, its special feature is preheat roll, large warm-up mill, doff roll, the spraying of the roller area of heating surface or the spraying plating of temperature refining roller have adherent layer.This adherent layer is Teflon.Plastic sheeting is in the situation that high temperature, the physical property on surface can change, its adhesion property has obvious enhancing, employing is at corresponding higher roller surface spraying or the spraying plating adherent layer of surface temperature, just can effectively prevent that plastic sheeting from sticking on the warm-up mill surface, guarantee stable in the physical aspect of transmitting procedure of plastic foil.

Here, the diameter of large warm-up mill is more than 1200mm.Adopt large diameter large warm-up mill, increased the compound length of plastic foil, thereby, effectively in the situation that guarantee composite effect, improved the speed of production of composite membrane.

Here, the doff roll back of thermal composite machine structure is provided with the emboss with dandy roll, and the temperature refining roller of cooling body, chill roll are arranged on movable machine frame, and movable machine frame is arranged on guide rail.During use, when needs are changed the dandy roll on emboss, movable machine frame is pulled open along guide rail, to avoid cooling body to hinder the dismounting of dandy roll, after more finishing changing dandy roll, again movable machine frame is pushed back to the position of setting, to shorten as far as possible the spacing between emboss and cooling body, avoid causing because the spacing between emboss and cooling body is excessive the two inter-agency stretching that plastic foil drops and irregular deformation causes and other mass defects.

Chill roll has more than 12; the cavity volume of front 3-5 chill rolls imports hot water; other chill roll cavity volume imports cold water or freezes water; the diaphragm composite structure is arranged on movable machine frame, and last chill roll or cavity volume that the diaphragm introducing port of diaphragm composite structure is positioned at cavity volume importing hot water import on the top chill roll of cold water.In the production process of composite membrane, after Film laminated, all need the mode of progressively lowering the temperature to eliminate internal stress, and the pasting of diaphragm, along with the temperature of laminated film is higher, adhering effect is better, therefore, if carry out pasting of diaphragm at the laminated film high temperature dot, pasting can be very firm, but, because the internal stress of laminated film is not now also eliminated, therefore, elimination along with internal stress, some variations can occur in the physical aspect of laminated film, because not existing internal stress, diaphragm do not eliminate problem, therefore diaphragm can not synchronizeed with laminated film the variation that physical aspect occurs, will cause like this diaphragm the appearance of the bad phenomenon such as wrinkling to occur, if diaphragm is just pasted after the internal stress of laminated film is eliminated fully, because the temperature of laminated film has now dropped to normal temperature, therefore, can not utilize the performance of pasting that is used for strengthening diaphragm of high temperature, in order to guarantee the adhering effect of diaphragm, diaphragm with high costs, that the power of pasting is strong can only be adopted, like this, the cost of product will be increased.Last chill roll or cavity volume that the diaphragm introducing port of the diaphragm introducing mechanism of present patent application is positioned at cavity volume importing hot water import on the top chill roll of cold water; both made general diaphragm cheaply (as low bonding force diaphragm) can utilize the high temperature of laminated film to guarantee adhering effect; simultaneously; the internal stress of laminated film has been eliminated much to a certain extent, and the variation on the laminated film physical aspect that remaining internal stress causes has been not enough to affect the physical aspect of diaphragm.

Compared with the prior art the utility model, has advantages of and can prevent that the phenomenon that plastic sheeting sticks on the warm-up mill surface from occurring and can reduce manufacturing cost, improving production efficiency.
