Abstract
The utility model discloses a vacuum-drawing device for cleaning a thick sheet used for production of a biaxially oriented polypropylene thin film. The vacuum-drawing device comprises an upper vacuum box (2) and a lower vacuum box (5) which are fixed by a bracket (4), wherein the upper vacuum box (2) and the lower vacuum box (5) are respectively connected with a negative pressure fan (9) through an upper air pipe (10) and a lower air pipe (7). According to the vacuum-drawing device, the negative pressure fan is used for producing negative pressure; dust, volatile matters, water and the like on the upper surface and the lower surface of the thick sheet are sucked by the vacuum boxes, so that the cleanness of the thick sheet is improved; the high-quality thick sheet is supplied to the next production working procedure; and the quality of a product is improved.
Description
Technical field
The utility model relates to a kind of device of bidirectional stretching polypropylene film production usefulness, and particularly a kind of bidirectional stretching polypropylene film production is with sheet clean vacuum aspirator.
Background technology
In bidirectional stretching polypropylene film production line (BOPP) production process, be extruded from die head behind the raw material process extruder fusion plastification, after the cooling through sharp cooling roll, tank, form sheet, sheet can carry out biaxial tension through after dewatering.In actual production process; Sheet is after process dewaters, because long-time volatile matter gathering of producing in the tank is more, in addition; De-watering apparatus is to compress in advance through rubber roller to dewater; Blowing away the moisture on the sheet through high pressure positive blower air-supply simultaneously, is natural wind and blower fan is inhaled, can dust in air sucked and blow on the sheet.Like this, on sheet, just have the rubber dust of rubber roller wearing and tearing, the dust that blower fan blows, the materials such as volatility of raw material thing that tank water brings, polluted sheet, the quality of sheet is descended, the film that causes producing has impurity, has influenced product quality.
The utility model content
The purpose of the utility model is, provides a kind of bidirectional stretching polypropylene film production with sheet clean vacuum aspirator.The utility model can siphon away the impurity on the sheet, improves the cleanliness factor of sheet, has improved product quality.
The technical scheme of the utility model: a kind of bidirectional stretching polypropylene film production is with sheet clean vacuum aspirator; It is characterized in that: comprise that last vacuum tank is connected negative-pressure air fan through upcast ventilation pipe with lower air conduit respectively with following vacuum tank through support fixing last vacuum tank and following vacuum tank.
Aforesaid bidirectional stretching polypropylene film production is equipped with control valve with in the sheet clean vacuum aspirator on described upcast ventilation pipe and the lower air conduit.
Aforesaid bidirectional stretching polypropylene film production is with in the sheet clean vacuum aspirator, and the described vacuum tank of going up connects upcast ventilation pipe through last metal hose; The described warp of vacuum tank down metal hose down connects lower air conduit.
Aforesaid bidirectional stretching polypropylene film production is with in the sheet clean vacuum aspirator, and described negative-pressure air fan is the frequency conversion negative-pressure air fan.
Compared with prior art; The utility model produces negative pressure through negative-pressure air fan, utilize vacuum tank to the upper and lower surfaces of sheet on the suction carried out of impurity such as dust, volatile matter and water, improve the cleanliness factor of sheet; For next step production process provides high-quality sheet, improved product quality.The utility model also has the characteristics simple in structure and easy to use of implementing.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A kind of bidirectional stretching polypropylene film production is with sheet clean vacuum aspirator; Constitute as shown in Figure 1; Comprise the last vacuum tank 2 and following vacuum tank 5 fixed through support 4; Sheet 3 is installed between last vacuum tank 2 and the following vacuum tank 5, and last vacuum tank 2 is connected negative-pressure air fan 9 through upcast ventilation pipe 10 with lower air conduit 7 respectively with following vacuum tank 5.
Be equipped with control valve 8 on described upcast ventilation pipe 10 and the lower air conduit 7.
The described vacuum tank 2 of going up connects upcast ventilation pipe 10 through last metal hose 1; Described 5 warps of vacuum tank down metal hose 6 down connect lower air conduits 7.
Described negative-pressure air fan 9 is frequency conversion negative-pressure air fans.
The utility model produces negative pressure through negative-pressure air fan; Utilize vacuum tank to the upper and lower surfaces of sheet on the suction carried out of impurity such as dust, volatile matter and water; Improve the cleanliness factor of sheet,, improved product quality for next step production process provides high-quality sheet.The utility model also has the characteristics simple in structure and easy to use of implementing.
