Description
Technical field
The invention belongs to metalized film processing technique field, more particularly to for forming small dimension metallized film screen band
Spray equipment.
Background technology
Metalized film is exactly, in BOPP film or BOPET films surface evaporation metal aluminum and zinc, the coat of metal to be formed, according to user
Demand coat of metal width, retains a blank with one fixed width and stays side in coat of metal side, referred to as shields band, and blank is stayed
Border area must clearly without coating, and blank is stayed and connect between border area and the coat of metal clear, it is impossible to have ambiguous relief area.It is raw
Oiling shielding mode is generally adopted in product, i.e., before film vapor deposition, stays border area domain to spray one layer of oil film in advance in corresponding blank,
To prevent metal attachment during evaporation.
This spraying equipment for spraying shielding oil vapour to film surface be usually built-in electric heater in horizontal
The cylindric fuel tank of placement, the spraying area of top of oil-tank is provided with notch, and notch upper end is fixed with sealing baffle, and baffle plate is along length
Direction arranges the nozzle that oriented film surface sprays oil vapour, and on each nozzle correspondence thin film arranges the screen that blank stays side
Band.Oil vapour is formed after oil heating in fuel tank, the nozzle on Jing baffle plates is sprayed into the corresponding region of film surface.Due to steaming
Metallized thin film preparation early stage, it is necessary to which, first by the oil heating in fuel tank, the oil vapour volatilized after heating will certainly be from gear
Overflow in the nozzle of plate, pollute film surface, cause metallized film section start to have bright spot (i.e. oily pollution point) and cause coating
It is easy to fall off, affect product quality.
The content of the invention
The purpose of the present invention is to propose to a kind of spray equipment for forming metallized film screen band, can effectively prevent gold
There is bright spot in categoryization thin film section start, improves metallized film product quality.
For achieving the above object, present invention employs technical scheme below：
Including fuel tank and baffle plate, electric heater unit is provided with fuel tank, fuel tank top is provided with the oil filler refueled into case；Gear
It is provided with the nozzle for spraying oil vapour to film surface on plate along its length；It is characterized in that：Fuel tank upper end is provided with expansion box,
Spraying area at the top of expansion box is provided with notch, and baffle plate is fixed on the notch upper end of expansion box, expansion box be respectively arranged at two ends with
The gas channel that fuel tank upper cavity is communicated, on the gas channel at expansion box two ends electromagnetic valve is respectively provided with.
Because two cavitys of expansion box and fuel tank are completely independent setting, turned on by solenoid valve control between two cavitys
Or cut-off, the oil vapour in the fuel tank of bottom only could be in expansion box by solenoid valve control.When evaporation starts, in time
Electromagnetic valve is opened, the oil vapour in the fuel tank of bottom enters expansion box, by the nozzle on baffle plate thin film is evaporated to by electromagnetic valve
On surface, the coating for thus thoroughly solving metallization plated film section start bright spot position comes off problem.
Need to heat in advance due to being deposited with early stage fuel tank, to prevent during preparing, gas pressure is excessive in fuel tank, fuel tank top
It is provided with the air vent for decompression.
Further, the electromagnetic valve includes body portion, coiler part and movable valve plug, and expansion box two ends are provided with fixation
The cuddy board of body portion, body portion bottom is provided with air inlet and air vent, and movable valve plug lower vertical is arranged on valve body
In partial valve pocket, there is the sealing member for closing air vent in movable valve plug；Open on top of oil-tank and expansion box cuddy board
There is the inlet channel communicated with air inlet, the expansion box cuddy board of air vent lower end is provided with the aerofluxuss for leading to gas storage box cavity
Passage.Inlet and outlet passage is set on the cuddy board of expansion box, can electromagnetic valve be arranged on expansion box two ends so that whole dress
Put compact conformation.And the air vent of electromagnetic valve is arranged below, before opening a certain amount of oil of accumulation in valve pocket can steam valve body
Vapour so that when valve element is opened, the oil vapour in valve pocket can be promptly fills up in gas storage box cavity, be advantageously implemented metal evaporation
With the synchronization of oiling, can thoroughly solve starting and come off problem, save the use of shielding oil.
Preferably, movable valve plug lower end is provided with radially raised annular boss, and annular boss lower end is set with and aerofluxuss
The sealing ring that mouth upper surface coordinates.When valve element is closed, annular boss is downwards pressed on sealing ring on air vent upper surface, close
Envelope property is good.
The beneficial effects of the present invention is：By arranging between independent two cavitys of upper and lower cavity and solenoid valve control
Break-make, the time that oil vapour can be sprayed to film surface with precise control, so as to eliminate metallization plated film section start bright spot portion
The coating of position comes off problem problem so that coating concordance is good, can improve metallized film product quality.
