Description
Technical Field
The invention belongs to the technical field of liquid crystal glass cleaning, and particularly relates to an L-shaped support of an air knife supporting wheel.
Background
In a liquid crystal substrate glass manufacturing production line, glass is cut into semi-finished products after being formed, the semi-finished products can meet the requirements of finished products only after being finely cut, ground and cleaned, the production line is long, the processing process is complex, the plate surface is very dirty, so the glass needs to be cleaned and cleaned with high quality, the requirements of users can be met, the plate surface is wet after the glass is cleaned, the glass plate needs to be dried before being packaged, the cleaned glass can be inspected and packaged after being dried, the drying requirement of the glass plate surface is dried by clean air, in order to be dried uniformly, an air knife is usually used, the clean air is blown out by the air knife, the precision of the air knife is very high, the drying process is very strict, the substrate glass is very thin, the glass is required to flow horizontally and uniformly when passing through the air knife, and support wheels are arranged in front of, in middle of and behind the air knife and are all follow-up, accept glass in the twinkling of an eye, support glass, the prevention is sunken, because of the space between the air knife is little about, so adjust the supporting wheel and receive the restriction in space, inconvenient, inaccurate, adjust the supporting wheel in the middle of the air knife on the production line and just need experienced technician, and the adjustment time is very long, and the height of supporting wheel in the middle of the air knife is very microcosmic, and it directly influences the incidence of face water spot, influences the incidence of stain, influences PAC's height.
The prior art has the following problems: the thickness of common substrate glass is 0.40, 0.50 and 0.70, the thickness is very thin, the stress is easy to bend, the horizontal transmission is easy to drop, the last station of the substrate glass cleaning machine is air knife drying, the drying process is very strict, the drying is not dry or the air blowing is not uniform, the quality of the plate surface is directly influenced, if the substrate glass locally drops or abnormally rises before entering the air knife, namely the substrate glass is not in the same horizontal plane with the whole plate, the plate surface has more water points, PAC (poly aluminum chloride) height and stains, if the substrate glass passes through the middle of the air knife and is not received, or the head is dropped or raised, the water points of the front and rear short edges of the plate are raised, the PAC is raised, the stains are raised, the plate keeps stable movement through the air knife, the receiving of the front, middle and rear of the air knife mainly depends on supporting wheels, the front and rear supporting wheels of the air knife are separated by 50-80, the transverse supporting wheels are separated by 150-240 and are distributed among the conveying rollers, the supporting wheels are moved along with each other, the supporting wheels have smooth surfaces, strong self-cleaning capability and very flexible rotation, the height of the supporting wheels directly influences the level of board transmission and influences the drying quality of a board surface, so the adjusting technology of the supporting wheels is very critical, a certain space is reserved in front of and behind the air knife during adjustment, the supporting wheels in front of and behind the air knife are easy to adjust, the difficulty is high, the supporting wheels in the middle of the air knife are difficult to adjust, the key is that hands cannot extend into the supporting wheels, the front end of the front air knife is connected with the supporting wheels in the middle of the front air knife, the straight rod is combined with the rear support into a Z-shaped frame, the Z-shaped frame is fixed on a bottom plate, the supporting wheels are arranged on the Z-shaped frame, the supporting wheels are arranged at the front end of the straight rod and extend into the middle of the air knife, the rear end of the straight rod is fixed on the Z-shaped frame, the rear end of the straight rod is provided with a large hole, the large hole penetrates through the main shaft of the rear support, the main shaft is connected with the rear supporting wheels, the rear support and the straight rod to form a Z-shaped overall frame, the rear supporting wheel is arranged outside the air knife, the straight connecting rod and the rear supporting wheel are arranged on the same main shaft, the straight connecting rod can rotate, the front supporting wheel is driven to lift when the straight connecting rod rotates, the front part of the straight connecting rod acts when a hand rotates the rear end of the straight connecting rod, and therefore the straight connecting rod does not act accurately, is not high or low when adjusted, is poor in accuracy, and easily changes along with the rotation of a nut when locked on the main shaft, and therefore the adjustment accuracy of the straight connecting rod is not high.
