Abstract
The primary purpose of the invention is to discloses a method for eliminating glass wind spots, especially a method for eliminating wind spots formed when glass swinging stops; several wind gratings are disposed above and below a conveying roller; the wind gratings are uniformly distributed in the glass conveying direction to form a wind blowing covering area; during cooling, the glass is driven by the conveying roller to reciprocate in the wind blowing covering area in the glass conveying direction; when the moving direction of the glass changes, the wind gratings are moved to perform relative movement to the glass in the glass conveying direction. At the moment when the glass swings back, the phenomenon of nonuniform stress caused by glass stop is eliminated by the relative movement of the wind gratings. The secondary purpose of the invention is to discloses a wind grating swing mechanism.
Description
Technical field
The present invention relates to a kind of method of eliminating glass wind spot, especially eliminate the method for the wind spot forming on toughened glass by swinging air grid, and a kind of air grid tilting mechanism.
Background technology
Annealing furnace toughening process can be at the stress pattern (being commonly called as wind spot) that stays on glass, toughened glass wind spot is as an index of visual appearance, more and more receive people's concern, for wind spot is alleviated as far as possible, the sector technician has taked various ways, such as adopt accelerate glass come out of the stove speed, optimize wind hole arrangement, air grid side throw etc.But the formation of wind spot is complicated, need to consider that except plant width direction formation is cooling uniformly, the more important thing is the formation that also will consider to eliminate wind spot along device length direction.Up to the present, the wind spot of annealing furnace remains a flaw of toughened glass, and people wait in expectation can better wind spot reduction technology, makes the outward appearance of toughened glass better.
Summary of the invention
In order to weaken the formation of wind spot, the principle that we form from wind spot, makes glass wind-engaging process of cooling as far as possible evenly, does not form strong and weak uneven cooling point.According to experimental study, it is relevant that being formed on of wind spot stops in air grid with glass to a great extent, because, general annealing furnace air grid is limited in the area coverage of device length direction (glass throughput direction), and glass is cooling in air grid is a process that swings mobile blowing along device length direction.When glass is in the moment of backswing, the relative glass of air grid tuyere is that transitory phase is to static, at this, tuyere will be more than elsewhere in the corresponding wind-engaging region of glass surface in a flash, the tuyere of different patterns can form different wind-engaging regions at glass surface, but which kind of tuyere all can make glass surface form heavier wind spot because wind-engaging is uneven in relatively static moment.For this reason, primary and foremost purpose of the present invention is a kind of open method of wind spot forming when glass swinging stops of eliminating, and in the moment of glass backswing, by the relative movement of air grid, eliminates glass and stops the Stress non-homogeneity phenomenon causing; Secondary objective of the present invention is open a kind of air grid tilting mechanism.
To achieve these goals, a kind of method of eliminating glass wind spot of the present invention, the above and below of rollgang is provided with some air grids, described air grid is uniform along glass throughput direction, form a blowing coverage, in process of cooling, described rollgang drives glass to move back and forth along glass throughput direction in described blowing coverage; In the time that the travel direction of described glass changes, mobile described air grid, makes it on glass throughput direction, produce relative movement with glass.
Further, the speed of described air grid equates in the speed moving back and forth in process with glass.
A kind of air grid tilting mechanism, comprise rollgang, the above and below of described rollgang is provided with some air grids, described air grid is uniform along glass throughput direction, form a blowing coverage, in process of cooling, described rollgang drives glass to move back and forth along glass throughput direction in described blowing coverage; Air grid is movable, on air grid, be connected with and can promote air grid and move forward and backward driving mechanism along glass throughput direction, described driving mechanism connects promising its provides the actuating unit of power, described air grid tilting mechanism also comprises speed detector, described speed detector is for detection of the speed of glass, and in the time that glass throughput direction changes, send signal to driving mechanism.
Further, the speed of described air grid equates in the speed moving back and forth in process with glass.
Further, described actuating unit is reducing motor, and described driving mechanism is the crank and the connecting rod being connected with described crank being connected on reducing motor, and described connecting rod is connected on described air grid.
The present invention is by the formation of research wind spot, avoid glass relative with air grid static as far as possible, especially in the time of glass backswing, glass can be relatively static, make the relative glass motion of air grid, the movement velocity of the air grid with it speed of front glass is consistent, ensures that wind-engaging on glass is even as far as possible, reduces the formation of wind spot.
Brief description of the drawings
Fig. 1 is the structural representation of air grid tilting mechanism of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.
Embodiment 1
A kind of method of eliminating glass wind spot, the above and below of rollgang is provided with some air grids, and air grid is uniform along glass throughput direction, forms a blowing coverage, in process of cooling, rollgang drives glass to move back and forth along glass throughput direction in blowing coverage; In the time that the travel direction of glass changes, mobile air grid, makes it on glass throughput direction, produce relative movement with glass.In the time that glass changes travel direction, still ensureing has relative movement between air grid and glass, can not stop at glass surface, has effectively alleviated the formation of wind spot.The translational speed of air grid equates in the speed moving back and forth in process with glass.Glass is remained and the constant speed of relative movement of air grid in reciprocating whole process, and wind-engaging is cooling more even, further promotes the effect that reduces wind spot.
Embodiment 2
As shown in Figure 1, a kind of air grid tilting mechanism, comprise rollgang 1, the above and below of rollgang 1 is provided with some air grids 2, air grid 2 is uniform along glass 3 throughput directions, form a blowing coverage, in process of cooling, rollgang 1 drives glass 3 to move back and forth along glass 3 throughput directions in blowing coverage; Air grid 2 is movable, on air grid 2, be connected with and can promote air grid 2 and move forward and backward driving mechanism along glass 3 throughput directions, driving mechanism connects promising its provides the actuating unit of power, air grid 2 tilting mechanisms also comprise speed detector (not shown), speed detector is for detection of the speed of glass 3, and in the time that glass 3 throughput directions change, send signal to driving mechanism.The translational speed of air grid equates in the speed moving back and forth in process with glass.In the present embodiment, actuating unit is preferably reducing motor 6, the concrete structure of driving mechanism is the crank 5 and the connecting rod 4 being connected with crank 5 being connected on reducing motor 6, connecting rod 4 is connected on air grid 2, reducing motor 6 drives crank 5 to rotate, crank 5 drivening rods 4 move, and then promotion air grid 2 moves.
