As shown in Figure 1, a kind of coating machine, including rotor 1, paint roller 2, slurry baffle 5 and fixture 4.
To prevent slurry from leaking out at gap in coating process along clamping plate, foam pad, the utility model is by pressing from both sides
Increase dust-free paper on tool 4 and slurry baffle 5 to realize.
Firstly, it is specific as follows to increase dust-free paper on fixture 4:
Fixture 4 is usually two, is symmetrically fixed on slurry baffle 5 (fixed structure is not shown in fig. 1), is based on
The purposes of fixture 4 primarily to control foil coated face, therefore the installation site of fixture 4 can according to the size of coating machine and
The size of foil is adaptively adjusted, and which is not described herein again.
The front end of fixture 4 is tip, protrudes into and is held between rotor 1 and paint roller 2, fixture 4 is pressed from both sides by rotor 1 and paint roller 2
Foam pad (being not shown in attached drawing 1) and the first dust-free paper 3 are successively coated on the clamping face held from the inside to the outside.Folder mentioned here
It holds there are two the reality of face；One clamping face corresponds to rotor 1, therefore the clamping face is the circular arc table adaptable with the surface of rotor 1
Face；Another clamping face then corresponds to paint roller 2, therefore it is the arc-shaped surface adaptable with the surface of paint roller 2 that this, which holds face,；Two circular arcs
The clamping face of shape has been crossed to form the tip of 4 front end of fixture.
One layer of foam pad is coated on the clamping face of fixture 4, foam pad is strip, can generally be pasted in clamping face.
The first dust-free paper 3 is also coated on the clamping face for be coated with foam pad, which generally comprises at least two
The industrial dust-free paper of layer.Industrial dust-free paper is usually cut into strip as needed, such as being cut into width is 1cm-1.5cm, it is long
The strip for the several times that the strip or length that degree is 10cm-15cm are 10cm-15cm；Then as needed by several sanctions
The good industrial dust-free paper of strip stacks or is folded to edge and flushes.And dust-free paper is rolled up in coating process in order to prevent
Entering influences slurry in slurry, usually require that the edge of the industrial dust-free paper of the strip of cutting flushes impulse- free robustness.
Secondly, it is specific as follows to increase dust-free paper in the front end of slurry baffle 5:
The position that the front end of slurry baffle 5 corresponds to fixture 4 is provided with the second dust-free paper 6, which generally also wraps
Include at least two layers industrial dust-free paper.The production of second dust-free paper 6 is similar with the first dust-free paper 3, and will be industrial dustless
Paper is cut into strip, but size different from as needed, and the width of the second dust-free paper 6 is greater than the width of the first dust-free paper 3, and second
The length of dust-free paper 6 is not less than the length of the first dust-free paper 3；Such as being cut into width is 1.5cm-2cm, length 15cm-20cm
Strip or length be 15cm-20cm several times strip；Then as needed by several strip works cut out
Industry stacks or is folded to edge with dust-free paper and flushes.Similarly, dust-free paper is involved in slurry in coating process in order to prevent
Middle influence slurry also requires the edge of the industrial dust-free paper of strip cut to flush impulse- free robustness.
Second dust-free paper 6 is held between the front end of slurry baffle 5 and paint roller 2 (it should be noted that can not when installation
It is too tight, therefore, to assure that slow-roll stabilization when coating, also can not be too loose, to prevent slurry from oozing out leakage from gap), the second dust-free paper
The front end of slurry baffle 5 is stretched out in 6 front end, usually controls the length of stretching in 0.5cm-1cm.Described here second is dustless
The front end of paper 6 only passes through chucking power between the front end of slurry baffle 5 and paint roller 2 and is fixed, and the rear end of second dust-free paper 6
Then it is fixed on the lower surface of slurry baffle 5 by the modes such as pasting.
Although the foregoing describe specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
This is merely illustrative of, and the protection scope of the utility model is defined by the appended claims.Those skilled in the art
Under the premise of without departing substantially from the principles of the present invention and essence, many changes and modifications may be made,
But these change and modification each fall within the protection scope of the utility model.
