Description
Technical field
The utility model relates to a kind of tubular film production equipment, specifically a kind of cooling device of tubular film production equipment.
Background technology
Tubular film production equipment is production equipment plastic pellet heating and melting being blown out again film, and therefore film needs first to carry out rolling again through the process of a cooling and shaping.If the cooling for film is the mode adopting at room temperature cooling naturally, because room temperature is higher, general have certain fluctuation at about 20 DEG C, therefore film cooling is at room temperature in fact not only incomplete but also uneven, the constriction coefficient of the film after such rolling is considerably beyond its theoretical value, film is caused to occur serious became uneven phenomenon after finally having shunk, so-called NG (nogood) product namely become, so need a kind of cooling device cooled film specially.
The outer airduct that the current cooling device for film mainly adopts air-cooler cold wind to be blown into die head of film blowing machine carries out external refrigeration to film, its structure as shown in Figure 3, it is this that to lay project organization simple, easy to assembly, but, its disadvantage is exactly that heat loss is larger, because between the high temperature die head 1 ' that cold wind blast pipe 3 ' layout occupy outside and the hot blast exhaust duct 2 ' of inner side, heat exchange causes raising through overcooled EAT, thus reduction cooling effect, cause that its cooling effect is poor, uneven film thickness is even, film clarity is poor.Therefore, further improvement is necessary.
Utility model content
The purpose of this utility model aims to provide a kind of simple and reasonable, excellent performance, low cost of manufacture, easy production, easy realization, good cooling results and produce the cooling device of the tubular film production equipment that rear film thickness is even, transparency is high, to overcome weak point of the prior art.
The cooling device of a kind of tubular film production equipment designed by this object, comprises die head, hot blast exhaust duct and cold wind blast pipe, it is characterized in that: also comprise cold-hot wind commutation element; Described cold wind blast pipe is set in that hot blast exhaust duct is inner, and hot blast exhaust duct is arranged on die internal, and cold-hot wind commutation element to be arranged on die head and to be interconnected with hot blast exhaust duct and cold wind blast pipe respectively, to realize the cold air intake of interior pipe, outer tube hot type wind.
The inside of described cold-hot wind commutation element is provided with cold wind tube chamber and hot blast tube chamber, and cold wind tube chamber and cold wind blast pipe are interconnected, and hot blast tube chamber and hot blast exhaust duct are interconnected.
The top of described cold-hot wind commutation element is provided with commutation chamber, and top and the hot blast exhaust duct in commutation chamber are interconnected, and bottom is interconnected with cold wind tube chamber and hot blast tube chamber respectively; It is inner that described cold wind tube chamber is arranged on hot blast tube chamber, and the outside of hot blast tube chamber is also provided with cold wind discharge side.
The inside in described commutation chamber is provided with next door, next door is provided with some vertical air ports and hot blast tube chamber is interconnected, and next door is provided with some horizontal air ports and cold wind discharge side is interconnected.
The top of described cold wind discharge side, sidepiece and/or bottom are provided with some opening supply cold winds and discharge.
Ringwise, cold-hot wind commutation element ringwise and be arranged on the top of die head for described die head.
The utility model is by the improvement of said structure, adopt the design of different-diameter two hollow pipe mutual sheathing, a cold wind blast pipe is responsible for the replenish air of cooling is entered tubular film inside and strengthens cooling, a hot blast exhaust duct is responsible for the air absorbing heat is discharged, on high temperature die head, increase a set of cold-hot wind commutation element simultaneously, this cold-hot wind commutation element is interconnected with hot blast exhaust duct and cold wind blast pipe respectively, to realize the cold air intake of interior pipe, outer tube hot type wind; Compared with prior art, effectively can stop the heat transfer of high temperature die head to cold EAT, greatly increase the operating efficiency of cooling air intake, through actual measurement, the cooling air outlet temperature of the cold air intake of interior pipe is no more than 3 DEG C, and the film thickness produced is even, transparency is high, greatly improves the product qualified rate of tubular film production equipment.It has simple and reasonable, excellent performance, and low cost of manufacture is easily produced, and easily realizes, and the features such as good cooling results are practical.
