Description
Technical field
The utility model belongs to the plastic sheet machine technical field, relates to a kind of PVC heat-shrinkable film unit specifically.
Background technology
Thermal contraction print film packing is generally adopted in beverage bottle outside in the market; Because the shrinkage factor of thermal contraction print film of the prior art only can be within 35%～55%, thus bottleneck can't be wrapped, yet; Beverage bottle is shining upon down, makes the beverage in the beverage bottle rotten easily.Common thermal contraction print film is generally the PVC heat-shrinkable film; Usually adopt two bubble legal systems to make the PVC heat-shrinkable film in the prior art; Promptly at first be shaped through inflation; Cooling and shaping forms behind the last drawn, and the PVC heat-shrinkable film lateral shrinkage that processes through two bubble methods is merely 35%～55%.How can provide that a kind of can to produce horizontal percent thermal shrinkage be that the PVC heat-shrinkable film machine of 60%～65% thermal contraction print film consists of the urgent demand of people.
The utility model content
The utility model is in order to overcome the deficiency that prior art exists; Provide a kind of and can produce the PVC heat-shrinkable film unit that horizontal percent thermal shrinkage is 60%～65% thermal contraction print film; Make the thermal contraction print film can wrap bottleneck; Beverage in the protection bottle can not let the beverage in the bottle receive the sunlight direct projection.
The utility model is realized through following technical scheme: a kind of PVC heat-shrinkable film unit, and it is made up of main frame, subsidiary engine, winder and frame; Main frame comprises extruder, mould and vane; Subsidiary engine comprises first haulage gear, plintlet, two bubble parts and three bubble parts; Two bubble parts comprise two bubble heating water tank, second haulage gear, two bubble typing water jacket, the 3rd haulage gear and middle clamp plates, and two bubble heating water tank, second haulage gear and two bubble typing water jackets are installed on the forebay; Three bubble parts comprise heating cabinet, the 4th haulage gear, three bubble typing water jacket, the 5th haulage gear and big clamp plates; On lower bearing bracket, install frame through rotating mechanism; The 5th haulage gear, big clamp plate, winder are installed on upper spider and power supply is introduced the rotation conducting ring of upper spider, winder comprises the 6th haulage gear and double rolling-up mechanism.
Crane is installed on upper spider.
Rotating mechanism comprises the rotation fluted disc, and the rotation fluted disc is connected with drive of motor through decelerator.
The beneficial effect of the utility model is: the PVC heat-shrinkable film unit of the utility model adopts three bubble methods to stretch through inflation and thermal finalization is handled; Three bubble methods are controlled at the embryonic tube temperature more than the vitrification point; Below the fusing point; Stretch then and inflation; Make the PVC heat-shrinkable film that processes have good barrier properties for gases, protect fragrant sealing, stiffness and thermal contraction formability, be widely used in the fit shrink wrapping of tea beverage, dairy products, frozen food and out-of-shape object.The utility model can promote the lateral shrinkage of PVC heat-shrinkable film greatly, and making its lateral shrinkage is 60%～65%, makes the thermal contraction print film can wrap bottleneck, and the beverage in the protection bottle can not let the beverage in the bottle receive the sunlight direct projection.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in detail.
As shown in Figure 1, a kind of PVC heat-shrinkable film unit, it is made up of main frame, subsidiary engine, winder and frame; Main frame comprises extruder 1, mould 2 and vane 3; Subsidiary engine comprises first haulage gear 4, plintlet 5, two bubble parts and three bubble parts; Two bubble parts comprise that two bubble heating water tank 6, second haulage gear 7, two bubble typing water jackets 8, the 3rd haulage gear 9 and middle clamp plate 10, two bubble heating water tank 6, second haulage gear 7 and two bubble typing water jackets 8 are installed on the forebay 11; Three bubble parts comprise that heating cabinet 12, the 4th haulage gear 13, three steep typing water jacket 14, the 5th haulage gear 15 and big clamp plates 16; On lower bearing bracket 22, install frame 17 through rotating mechanism; The 5th haulage gear 15, big clamp plate 16, winder are installed on upper spider 17 and power supply is introduced the rotation conducting ring 18 of upper spider 17, winder comprises the 6th haulage gear 19 and double rolling-up mechanism 20.Crane 21 is installed on upper spider 17, and rotating mechanism comprises rotation fluted disc 23, and rotation fluted disc 23 is connected with drive of motor through decelerator.
The three bubble technologies of using the PVC heat-shrinkable film unit of the utility model are: a bubble is extruded: adopt the flat upper blowing method that squeezes to extrude embryonic tube; Two bubble inflation: PVC get into two bubble heating water tank 6 and two bubble typing water jackets 8 after embryonic tube is extruded, utilize compressed air to carry out inflation; Three bubble typings: the PVC film behind the two bubble inflations is carried out three bubble typings handle, successively through heating cabinet 12 and three bubble typing water jackets 14, after the winder rolling.
Should be noted that at last; Above content is only in order to explain the technical scheme of the utility model; But not to the restriction of the utility model protection domain; The simple modification that those of ordinary skill in the art carries out the technical scheme of the utility model perhaps is equal to replacement, does not all break away from the essence and the scope of the utility model technical scheme.
