Abstract
The invention discloses a heat-shrinkable PVC film unit. The heat-shrinkable PVC film unit is composed of a primary machine, an auxiliary machine, a winding machine and frames; the primary machine comprises an extruder, a die and a vane; the auxiliary machine comprises a first traction mechanism, small clamping plates, a second foaming portion and a third foaming portion, the second foaming portion comprises a second heating water case, a second traction mechanism, a second foaming fixing water jacket, a third traction mechanism and medium clamping plates, and the second heating water case, the second traction mechanism and the second foaming fixing water jacket are arranged on a front frame; and the third foaming portion comprises a heating case, a fourth traction mechanism, a third foaming fixing water jacket, a fifth traction mechanism and large clamping plates, an upper frame is arranged on a lower frame through a rotation mechanism, and the winding machine comprises a sixth traction mechanism and a double-station winding mechanism. The heat-shrinkable PVC film unit substantially raises the transverse shrinkage rate of a heat-shrinkable PVC film to 60-65%, and allows a hot-shrinkable print film to wrap a bottleneck in order to protect a beverage in the bottle and prevent the beverage in the bottle from direct sunlight.
Description
Technical field
The invention belongs to the plastic sheet machine technical field, relate 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, namely at first be shaped through inflation, form finally by the back cooling and shaping that stretches, the PVC heat-shrinkable film lateral shrinkage that processes by two bubble methods only is 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.
Summary of the invention
The present invention 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, the beverage in the protection bottle can not allow the beverage in the bottle be subjected to the sunlight direct projection.
The present invention is achieved by the following technical solutions: 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 by rotating mechanism, the 5th haulage gear, big clamp plate, winder are installed and power supply is introduced the rotation conducting ring of upper spider at upper spider, winder comprises the 6th haulage gear and double rolling-up mechanism.
At upper spider crane is installed.
Rotating mechanism comprises the rotation fluted disc, and the rotation fluted disc is in transmission connection by decelerator and motor.
The invention has the beneficial effects as follows: PVC heat-shrinkable film unit of the present invention adopts three bubble methods to stretch through inflation and thermal finalization is handled, three bubble methods are controlled the embryonic tube temperature more than 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 present invention 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 allow the beverage in the bottle be subjected to the sunlight direct projection.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention 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 heating cabinet 12, the 4th haulage gear 13, three bubble typing water jacket 14, the 5th haulage gear 15 and big clamp plates 16, on lower bearing bracket 22, install frame 17 by rotating mechanism, the 5th haulage gear 15, big clamp plate 16, winder are installed and power supply is introduced the rotation conducting ring 18 of upper spider 17 at upper spider 17, winder comprises the 6th haulage gear 19 and double rolling-up mechanism 20.At upper spider 17 crane 21 is installed, rotating mechanism comprises rotation fluted disc 23, and rotation fluted disc 23 is in transmission connection by decelerator and motor.
The three bubble technologies of using PVC heat-shrinkable film unit of the present invention are: a bubble is extruded: adopt the flat upper blowing method that squeezes to extrude embryonic tube; Two bubble inflation: PVC enter 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 by heating cabinet 12 and three bubble typing water jackets 14, finally by the winder rolling.
