State doctor blade device；There are 30 ° of -40 ° of angles, for adjusting the vane body and its between the side of clamping plate and the side of base
Angle between contact surface.
Optionally, the material of the vane body is fluorubber.
Optionally, the adjusting bracket also has backing plate, and the backing plate is between clamping plate and vane body, for protecting
Vane body.
Optionally, the shape of the vane body is pentagon.
Optionally, the head of the vane body is pentagonal top, and the bottom of the vane body is pentagonal
Bottom, it has two right angles.
Optionally, the adjusting bracket is provided with adjustable section, for adjusting the angle between clamping plate and base.
Compared with prior art, technical solution provided by the invention has the following advantages：
The present invention uses the design of adjusting bracket, by the way that the angle between the side of clamping plate and the side of base is arranged to
It can adjust, and allow the control of its angle in the range of 30 ° -40 ° so that the vane body is in contact with it the angle energy between face
Enough in suitable scope, so that slurry more neatly can be equably applied to object by the vane body
On.In addition, the head of vane body also has 65 ° of -75 ° of angles, it can coordinate whole adjusting bracket to carry out printing operation, into
One step improves the uniformity for scraping slurry, while also reduces need pressure to be used, so that be conducive to protect web plate, and then
The cost of technique productions is saved.
In alternative, the new material of the material selection fluorubber of the vane body, since fluorubber has preferably
Chemical resistance and mechanical performance, can improve the service life of the vane body, so as to reduce solar cell work
The cost of skill production.
Brief description of the drawings
Fig. 1 is the structure diagram of one embodiment of the invention doctor blade device.
Embodiment
From background technology, the quality and performance for being currently used for the doctor blade device of solar cell printing need to be carried
It is high.
To solve the above-mentioned problems, the present invention provides a kind of doctor blade device, is printed for solar cell, including blade master
Body and adjusting bracket.In technical scheme, the head of the vane body has 65 ° of -75 ° of angles, its angle is set
Meter coordinates adjusting bracket so that angle can be adjusted between the vane body is in contact with it face, and user is utilizing tool
When the solar cell printing press for having the doctor blade device is operated, it can avoid because causing to starch using larger pressure
Material is brushed uneven, while also improves the service life of web plate.Specifically, between the side of the clamping plate and the side of base
Angle be 30 ° -40 °, so as to avoid being set excessive or too small because of angle, and cause the use of the doctor blade device
Degradation.
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
With reference to figure 1, Fig. 1 shows the structure diagram of one embodiment of the invention doctor blade device.The doctor blade device, is used for
Solar cell prints, including：Vane body 100, it has 65 ° of -75 ° of angle β with head and bottom, the head；Adjust
Stent (not indicating) is saved, it is used to fix vane body 100, the base with clamping plate 120 and base 140, the clamping plate 120
140 are used to support the doctor blade device；There are 30 ° of -40 ° of angle αs between the side of clamping plate 120 and the side of base 140, be used for
Adjust the angle that the vane body 100 is in contact with it between face.
In the present embodiment, the clamping plate 120 is fixed vane body 100 by screw 130, the peace of vane body 100
Dress and elastic adjust are carried out by screw 130.
The present invention uses the design of adjusting bracket, by by the angle between the side of clamping plate 120 and the side of base 140
