Description
Technical field
The utility model relates to eva film production equipment technologies, are fed and fill more particularly, to a kind of eva film vacuum
It sets.
Background technique
Eva film also has title EVA adhesive film, is the material applied to solar photovoltaic assembly encapsulation, eva film production
Raw material, be mixed into pulp-like, slurry is squeezed after heating stove heating is added, and forms film by die head.It is existing
Some raw material feeding styles are usually manually operated, and by the way that hopper is added in raw material, then raw material is led with lifting device
The problem of entering feeding chamber, then carry out next step production, operating in this way is that charging may will lead to scarce material not in time, is added too early
Material, and raw material can be made to contact more air, since eva film production is very high to raw material purity requirements, in this way may
Generate hidden danger of quality.
Summary of the invention
The utility model is the automation and cleanliness in order to solve the problems, such as current eva film production charging, provides one kind
It is structurally reasonable, it is easy to operate, it is increasingly automated and greatly reduce the eva film vacuum charging gear that raw material is contacted with air.
To achieve the goals above, the utility model uses following technical scheme: eva film vacuum charging gear, including
Feedstock supply unit, vacuum evacuation device, pure air feeding mechanism further include the feed being connected to eva film production heating furnace
Storehouse, the feed hopper is connected to feedstock supply unit, vacuum evacuation device, pure air feeding mechanism pipeline respectively, described to give
Automatic switch valve is equipped on the connecting pipe of feed bin and each device.This programme is to reduce feed hopper (feeding chamber) and outside air
The chance of contact when charging, closes feed hopper and heating furnace, pure air feeding mechanism connecting pipe using closed charging
On automatic switch valve, open feed hopper and feedstock supply unit, the automatic switch valve on vacuum evacuation device connecting pipe, at this time
Vacuum evacuation device starting, feed hopper is vacuumized to form negative pressure, the negative pressure of feed hopper can the raw material of feedstock supply unit from
Inspiration feed hopper in pipeline after feed hopper charging, is closed and opening on feedstock supply unit, vacuum evacuation device connecting pipe automatically
Valve, opening and the automatic switch valve on heating furnace, pure air feeding mechanism connecting pipe are closed, pure air feeding mechanism is empty
Air pressure enters feed hopper, material extruding into heating furnace；Then it repeats to be fed to feed hopper；Each device of this programme is by automatically controlling system
System control.
Preferably, the feedstock supply unit includes head tank, feeding device, the head tank and feed storekeeper
Road is connected to and is equipped with level sensor, and the feeding device includes mixer, dosing pump.This programme raw material is configured in mixer
It completes, feed hopper draws raw material from head tank, and after raw material is finished in head tank, the raw material in mixer is pumped in time by dosing pump
Enter in head tank；Head tank is equipped with air access ports, draws raw material after facilitating feed hopper negative pressure.
Preferably, the vacuum evacuation device includes vacuum pump, vacuum barrel, the vacuum barrel and feed hopper pipeline connect
It is logical.The vacuum barrel of this programme setting, can keep negative pressure at any time, can the shape in feed hopper quickly when feed hopper is connected to vacuum barrel
At the required negative pressure reached；When vacuum barrel negative pressure deficiency, vacuum pump startup is vacuumized.
Preferably, the pure air feeding mechanism includes air filter, air pump, the air pump respectively with sky
Air filter, the connection of feed hopper pipeline.The cleanliness of eva film production site environment itself has required to be maintained at higher journey
Degree, but to ensure the air cleaning into feed hopper, install air filter additional before air pump, it is ensured that it pressurizes to feed hopper
When, impurity will not enter with air.
Therefore, the utility model has the following beneficial effects: (1) is structurally reasonable；(2) easy to operate；(3) increasingly automated
And greatly reduces raw material and contacted with air.
