Wherein, at least one end of described smoothing roller arranges described waste liquid scavenge unit.
Preferably, the quantity of described waste liquid scavenge unit is two, is separately positioned on two side positions of smoothing roller.
(3) beneficial effect
Compare with product with prior art, the utility model has following advantage:
1, groove liquid knockout of the present utility model is compared and is removed the smoothing roller waste liquid manually and gather waste liquid in the groove, and the waste liquid that can in time will accumulate in the smoothing roller side grooves is efficiently disposed;
2, the utility model adopts the groove liquid knockout in time to remove the smoothing roller waste liquid and gathers waste liquid in the groove, and on the scraping fluid device of the side of groove liquid knockout, also be provided with waste liquid and get rid of the gap, avoid waste liquid to gather flowing backwards to be dropped in along scraper influencing product quality on the smoothing roller;
When 3, the scraper of existing smoothing roller carried out the drawout operation to polyimides (PI) liquid, waste liquid gathered the groove from scraper two side inflow smoothing roller waste liquids.Owing to be subjected to smoothing roller to rotate centrifugal force and the waste liquid gravity effect that causes, some waste liquids accumulate in position, smoothing roller both sides of the edge easily, flow and do not gather the groove place to waste liquid, caused polyimides (PI) liquid distribution of rib positions, smoothing roller both sides of the edge also inhomogeneous; The utility model can be by side scraping fluid device and positive scraping fluid device simultaneously to the smoothing roller drawout, and polyimides (PI) liquid that smoothing roller edge rib is inhomogeneous is drawout again, avoids printing bad generation, has guaranteed printing effect.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is made a detailed explanation.
Present embodiment relates to alignment films print field in the LCD preparation process.Present embodiment provides a kind of novel smoothing roller waste liquid scavenge unit.Shown in Fig. 2,3, this device comprises stationary fixture 8 and groove liquid knockout 5, and anchor clamps driving arrangement 6 is used for driving stationary fixture 8, and described groove liquid knockout 5 is fixedly connected on this stationary fixture 8.Particularly, adopt tight lock screw 9 that the groove liquid knockout is fixed on the stationary fixture 8; The waste liquid that described groove liquid knockout 5 can corresponding probe into smoothing roller 1 gathers in the groove 4, along with the rotation of smoothing roller 1, waste liquid is got rid of.
Above-mentioned groove liquid knockout can contain multiple version, as using materials such as sponge to make the groove liquid knockout waste liquid that accumulates in the groove is collected.As Fig. 2, Fig. 3 and shown in Figure 4, the groove liquid knockout 5 that present embodiment provides comprises side scraping fluid device 10 and positive scraping fluid device 11; Scraping fluid device 10 upper ends, described side are provided with bulge-structure 12, this bulge-structure 12 is corresponding with the shape that waste liquid gathers groove 4, side scraping fluid device 10 can make bulge-structure 12 correspondences probe into waste liquid and gather in the groove 4, in the rotary course of smoothing roller, waste liquid can be gathered the groove from waste liquid and discharge, flow out along smoothing roller axle 2.Also be provided with waste liquid between side scraping fluid device 10 and the positive scraping fluid device 11 and get rid of the gap, when the boss structure 12 of side scraping fluid device probes into after waste liquid gathers in the groove 4, waste liquid can be got rid of the gap along waste liquid and flow out.The side of side scraping fluid device 10 is provided with side scraping fluid blade 13; This side scraping fluid blade 13 can be cleared up the waste liquid that gathers of the side of smoothing roller.In addition, as shown in Figure 5, positive scraping fluid device 11 places close smoothing roller 1 one sides of described side scraping fluid device 10.Positive scraping fluid device 11 can be to inhomogeneous polyimides (PI) liquid in the smoothing roller surface that scraper causes drawout again.The top edge of positive scraping fluid device 11 is provided with positive scraping fluid blade 11a.Described positive scraping fluid device 11 and 10 splicings of side scraping fluid device are installed on the stationary fixture 8, form waste liquid between them and get rid of the gap.The width that this waste liquid is got rid of the gap is the best with 2～4mm, can be in the confined space, and effectively effluent discharge.When producing, the waste liquid of smoothing roller gathers groove and gathers waste liquid for 4 li, and the waste liquid that the waste liquid that side scraping fluid device 10 will accumulate in the smoothing roller both sides gathers 4 li of grooves strikes off, and the waste liquid along between side scraping fluid device and positive scraping fluid device is got rid of the gap and discharged.The material of side scraping fluid device and positive scraping fluid device is made except adopting stainless steel, also can adopt materials such as polyester resin PET, polytetrafluoroethylene PTFE or high density polyethylene to make.
Anchor clamps driving arrangement 6 is connected with stationary fixture 8 by connecting axle 7, connecting axle 7 is arranged on the stationary fixture 8, can control connecting axle 7 rotations by anchor clamps driving arrangement 6, thereby drive stationary fixture 8 rotations, in order to regulate the amount of being pressed into of the 5 pairs of smoothing rollers of groove liquid knockout on the stationary fixture 8 and be pressed into direction, the waste liquid of fully removing on the smoothing roller gathers the interior waste liquid of groove.
Certainly, the quantity of the groove liquid knockout of this waste liquid scavenge unit changeable shape and size and use satisfies the requirement of the smoothing roller of different size and shape.At least one end of smoothing roller arranges described waste liquid scavenge unit.Present embodiment preferably adopts the structure of two groove liquid knockouts, and described two groove liquid knockouts in axial direction are arranged on two side positions of smoothing roller accordingly.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
