Description
Technical field
The present invention relates to a kind of high accuracy spreader.
Background technology
At present, prepare in the thin-film process at rubbing method, nano level membrane equipment generally adopts the vacuum coating mode, and its filming equipment cost is very expensive.And the coating of traditional transfer method can not be satisfied nanoscale film preparation requirement.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of high accuracy spreader, this spreader not only can low-costly prepare the nanoscale film, and can replace existing transfer coated mode, the preparation general thin, and precision is higher.The spreader coating weight is controlled by measuring pump, and is easy to use, and can once be coated with, and realizes one or more layers film, and the even no disadvantage of coating.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of high accuracy spreader; It comprises top slice, following weir plate, first member plate, right end plate, left foam-discharging valve and right foam-discharging valve; Following weir plate be the below as benchmark, the sealing of said top slice is fixedly arranged on said weir plate down top; Said first member plate sealing is fixedly arranged on the left of said upper and lower weir plate, and said right end plate sealing is fixedly arranged on the right-hand of said upper and lower weir plate; Said left foam-discharging valve is located on the left surface of said first member plate, and said right foam-discharging valve is located on the right flank of said right end plate; Be provided with the coating medium chamber in the weir plate down said, be provided with charging aperture, said charging aperture and the chamber conducting of said coating medium on said weir plate surface down; Said left foam-discharging valve and said right foam-discharging valve respectively with the chamber conducting of said coating medium; On said weir plate down, be provided with in addition and be coated with the cloth seam, the said cloth that is coated with stitches an end and chamber conducting of said coating medium and other end formation coating port.During use, at first be communicated with charging aperture to a measuring pump, and calculate the required material scale of construction to be coated according to actual needs; And make the coating medium body enter into the coating medium chamber through charging aperture from measuring pump through pressure control, and open left and right foam-discharging valve then, make air through left and right foam-discharging valve discharge in coating medium the chamber in; Treated that the material body when left and right foam-discharging valve is discharged, even air drains in coating medium the chamber in, closes foam-discharging valve at this moment; Begin coating then; During coating,, just can evenly coat on the base material because measuring pump makes the material body extrude through the cloth seam that is coated with between the upper and lower weir plate.When the segmentation of needs gap is coated with, adopt feeding manner from bottom to top, because the material body overbottom pressure in the coating medium chamber can offset with its gravity, thereby can avoid the omission of material body when charging from top to bottom, the gap segmentation is coated with better effects if.
As further improvement of the present invention, said coating medium chamber is at least one, and said charging aperture is at least one, and said to be coated with that cloth is stitched to be one less.
As further improvement of the present invention; Said coating medium chamber, charging aperture and be coated with cloth seam and be one; And said coating medium chamber is positioned at the said upper surface center of weir plate down, and said charging aperture is positioned at the said lower surface center of weir plate down, and the said cloth seam that is coated with is between said upper and lower weir plate.
As further improvement of the present invention, said coating medium chamber is two, laterally arrange and conducting between the two about said two coating medium chambeies, said one of them coating medium chamber be coated with cloth seam conducting, another coating medium chamber and said charging aperture conducting.During use, the material body earlier gets into a coating medium chamber by charging aperture, gets into another coating medium chamber again, from be coated with the cloth seam, discharges at last and begins coating, and like this, coating can be more even.
As further improvement of the present invention, said charging aperture is a plurality of, and said charging aperture is symmetrically distributed in said weir plate lower surface down middle part.
As further improvement of the present invention, said spreader is processed by high molybdenum special steel.Like this, can effectively resist coating medium body wearing and tearing spreader.
As further improvement of the present invention, the said side roughness that is coated with the cloth seam is less than 1 μ m.
The invention has the beneficial effects as follows: 1. spreader adopts the processing and manufacturing of high molybdenum special steel, can effectively resist coating feed liquid wearing and tearing spreader, causes the coating precise decreasing; 2. spreader weir plate lip adopts correct grinding to obtain; 3. the spreader cavity can adopt the variable cross-section design according to the rheological behavior of coating feed liquid; 4. spreader adopts middle or multitube mouth feeding manner, can effectively improve the coating transverse regularity; 5. spreader adopts feeding manner from bottom to top, makes the segmentation coating process be coated with in the batch process, and feed liquid overbottom pressure and feed liquid gravity offset in the cavity, obtain desirable subsection efect.In sum, spreader can carry out the preparation of high accuracy (it is good laterally to reach vertical consistency property) film in this, the segmentation coating process that can realize ideal simultaneously.
