Abstract

Winding membrane stretching device, it is equipped with the air heater including unreeling axle, the back shaft of a plurality of height interval arrangement straggly, rolling axle in a high -order back shaft top wherein, the rotational speed that unreels the axle is less than the rotational speed of rolling axle. The utility model discloses eight piece total back shafts are equipped with the air heater in high -order back shaft top at third root back shaft promptly. The rotational speed that unreels the axle is the third of the rolling speed of spindle. Five, the position adjustment of horizontal direction, other back shafts rigid can be to the 7th back shaft. The temperature of air heater is 40-70 DEG C. Adopting winding membrane stretching device will twine the tensile back of membrane, making winding membrane attenuation extension form light and thin type membrane book, roll up the extension twice than former membrane, manual hand packaging services's goods volume increases, comparing with traditional winding membrane, packing the same goods, winding membrane quantity is few, and package cost is low.

Description

Winding film stretching device

Technical field

The utility model relates to a kind of stretching device, particularly the winding film stretching device in film production workshop.

Background technology

Be wound around the organic use of film and hand with two types, machine adopts Machinary Packaging operation exactly with film, and hand is with being exactly Manual Packaging. After winding film stretching being gone out to certain proportion by machine when machine press-packing, be rolled in again on goods, Manual Packaging is because the tensile force of hand is little, being wound around film is just stretched on a small quantity, cannot stretch being to greatest extent wound around film, so winding film of specification of the same race, adopt different packaging methods, Manual Packaging is higher than the packing cost of machine press-packing comparatively speaking, because the winding film that it consumes is more.

Utility model content

The purpose of this utility model, is that a kind of winding film stretching device will be provided, and it elongates winding film thin to greatest extent, facilitates Manual Packaging, reaches the maximum packing utilization rate that is wound around film, reduces packing cost.

The utility model is achieved in that described winding film stretching device, and it comprises unreeling shaft, some height spaced back shaft straggly, Scroll, and a high-order back shaft top is therein provided with air-heater; The rotating speed of unreeling shaft is less than the rotating speed of Scroll.

The utility model has eight back shafts, above the 3rd back shaft is high-order back shaft, is provided with air-heater.

The rotating speed of unreeling shaft described in the utility model is 1/3rd of Scroll rotating speed.

The the 5th, the 7th back shaft described in the utility model can do the position adjustment of horizontal direction, and other back shaft maintains static.

The temperature of air-heater described in the utility model is 40～70 DEG C.

The beneficial effects of the utility model are that employing winding film stretching device, by after winding film stretching, makes to be wound around film attenuation elongation and forms light and thin type film volume, than former film volume elongation twice, the car loading increase of Manual Packaging; But its hot strength, looping power and anti-puncture intensity are all substantially constant, as after stretching, thickness is the winding film of 10 μ m, and can reach thickness is firm performance and the barrier propterty that 18～20 μ m tradition are wound around film packaging. And without adopting special packing mechanical equipment, just can pack by hand, compared with traditional winding film, pack identical goods, winding film consumption is few, and packing cost is low.

Detailed description of the invention

Winding film stretching device described in the utility model, as shown in Figure 1, it comprises unreeling shaft 9, some height spaced back shaft straggly, Scroll 10, a high-order back shaft top is therein provided with air-heater 11; The rotating speed of unreeling shaft 9 is less than the rotating speed of Scroll 10. The utility model has eight back shafts, and back shaft 1,2,3,4,5,6,7,8 is provided with air-heater 11 above back shaft 3 is high-order back shaft. The rotating speed of unreeling shaft 9 described in the utility model is 1/3rd of Scroll 10 rotating speeds. Back shaft 5,7 described in the utility model can do the position adjustment of horizontal direction, and other back shaft maintains static. The temperature of air-heater 11 described in the utility model is 40～70 DEG C.

Produce stretch wrap film with the utility model, made by following steps:

1, winding film 12, through hyperextension winding film stretching device after unreeling shaft 9 pull-outs, carries out micro-softening processing of heating by air-heater 11 to being wound around film 12.

2, be finished product to being subject to winding film after temperature to carry out after stretch processing through Scroll 10 rollings.

Specific practice is:

Twining stretches processed by temperature: be wound around film 12 film bodies through stretching device from unreeling shaft 9 pull-outs, open stretching device and set approximately 40～70 DEG C of air-heater 11 temperature, blow out hot blast by air-heater 11 and carry out micro-heating to being wound around film, be subject to the winding film after temperature softening but indeformable.

Be subject to the rear winding film stretching processing method of temperature: be subject to the winding film after temperature to move back shaft 8 to through back shaft 4, be wound around film and stretch by the following method, then rolling between unreeling shaft 9 and Scroll 10.

If unreeling shaft 9, Scroll 10 diameters are consistent, Scroll 10 velocities of rotation are greater than unreeling shaft 9 velocities of rotation, best mode is: the rotating speed of unreeling shaft is one to three with Scroll rotating ratio, and the temperature of air-heater is 50 DEG C, is wound around like this film and can be stretched and has more two double-lengths. In Fig. 1, arrow represents to be wound around the direction that film advances.
