Abstract

The utility model belongs to the technical field of thin film preparation, and concretely relates to a cast piece unit water removal structure of a BOPP thin film production line. The water removal structure comprises a corona roller, a water tank, a transmission roller, water squeeze rollers and air knives, wherein a film sequentially passes through the corona roller and the transmission roller and sequentially enters the water squeeze roller I, the water squeeze roller II and the water squeeze roller III which are sequentially arranged along a film squeezing sequence; the position of the water squeeze roller I enables the film to be perpendicular with the water surface of the water tank; the water squeeze roller I, the water squeeze roller II and the water squeeze roller III are not arranged in a same vertical plane, and the perpendicular distance from the water squeeze roller I to the water surface of the water tank is 70cm-150cm. The multiple water squeeze rollers are adopted, and the air knives are arranged above the last water squeeze roller, so that the amount of the air knives is reduced, the electric energy used in the production process is reduced, the effects of energy conservation and emission reduction are achieved, and the production cost is reduced.

Description

A kind of BOPP film line slab unit water removing structure

Technical field

The utility model is film preparation field, is a kind of BOPP film line slab unit water removing structure specifically.

Background technology

In BOPP production line slab unit removal process, if causing, the bad meeting of water removal effect in drawing process, there is defect, have influence on the quality of monolithic film membrane, in general in order to improve water removal effect, adopt many Roots to remove Water fan and can improve the effect dewatering, but can cause the loss of electric energy, not meet the requirement of energy-saving and emission-reduction.Have the vertical increasing adopting between air knife and squeeze roll, adopting increases air-dry area and removes diaphragm moisture, but DeGrain.

Utility model content

It is a kind of for BOPP film line slab unit water removing structure that technical problem to be solved in the utility model is to provide, and is intended to eliminate the moisture of diaphragm, reduces the usage quantity of roots blower, saves production cost.

The utility model adopts following technical scheme:

A kind of BOPP film line slab unit water removing structure, comprise corona roller, tank, live-roller, squeeze roll and air knife, diaphragm enters in squeeze roll through live-roller through corona roller, described squeeze roll is three groups, according to the squeezed order of diaphragm, be followed successively by squeeze roll I, squeeze roll II and squeeze roll III, the position of squeeze roll I makes diaphragm vertical with the water surface of tank, and squeeze roll I, squeeze roll II and squeeze roll III be not each other in same vertical plane.

Further, the water surface vertical range of squeeze roll I and tank is 70～150cm.

The utlity model has following advantage and beneficial effect:

Adopt multiple tracks squeeze roll, and in the end the top of one squeeze roll arranges air knife, has reduced the usage quantity of air knife, has reduced the electric energy in production process, plays the effect of energy-saving and emission-reduction, reduces production costs;

Make dry very fast of moisture on diaphragm, need not underspeed, improved the quality of film;

Improve the water surface vertical range of squeeze roll I and tank, before not pushing, make the effect of the moisture dependence gravity on diaphragm, directly from diaphragm, fall, before water squeezing, removed most of moisture.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model embodiment;

In figure, 1 is that corona roller, 2 is that squeeze roll I, 3 is that squeeze roll II, 4 is that squeeze roll III, 5 is that air knife, 6 is that tank, 7 is live-roller.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

Embodiment

As shown in Figure 1, a kind of BOPP film line slab unit water removing structure, comprise corona roller 1, tank 6, live-roller 7, squeeze roll and air knife 5, diaphragm enters in squeeze roll through live-roller 7 through corona roller 1, squeeze roll is three groups, according to the squeezed order of diaphragm, be followed successively by squeeze roll I2, squeeze roll II3 and squeeze roll III4, the position of squeeze roll I2 makes diaphragm vertical with the water surface of tank, and squeeze roll I2, squeeze roll II3 and squeeze roll III4 be not each other in same vertical plane.The water surface vertical range of squeeze roll I2 and tank 6 is 120cm.

During use, improve the water surface vertical range of squeeze roll I and tank, before not pushing, make the effect of the moisture dependence gravity on diaphragm, directly from diaphragm, fall, before water squeezing, removed most of moisture.

Pass through again squeeze roll II and squeeze roll III, because squeeze roll I2, squeeze roll II3 and squeeze roll III4 be not each other in same vertical plane, making diaphragm is inclination, through squeeze roll I2, squeeze roll II3 and squeeze roll III4, make the two sides of diaphragm down lower like this, by moisture, the effect by gravity falls further.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.

Claims

1. a BOPP film line slab unit water removing structure, comprise corona roller, tank, live-roller, squeeze roll and air knife, it is characterized in that, diaphragm enters in squeeze roll through live-roller through corona roller, described squeeze roll is three groups, according to the squeezed order of diaphragm, be followed successively by squeeze roll I, squeeze roll II and squeeze roll III, the position of squeeze roll I makes diaphragm vertical with the water surface of tank, and squeeze roll I, squeeze roll II and squeeze roll III be not each other in same vertical plane.

2. according to BOPP film line slab claimed in claim 1 unit water removing structure, it is characterized in that, the water surface vertical range of squeeze roll I and tank is 70～150cm.
