Abstract
The primary and foremost purpose of the present invention is to disclose a kind of method eliminating glass wind speckle, the method especially eliminating the wind speckle formed when glass swinging stops, some air grids it are provided with above and below rollgang, described air grid is uniform along glass conveying direction, form a blowing coverage, in cooling procedure, described rollgang drives glass to move back and forth along glass conveying direction in described blowing coverage；When the moving direction of described glass changes, mobile described air grid so that it is produce relative motion with glass on glass conveying direction.In the moment of glass backswing, by the relative motion of air grid, eliminate glass and stop the Stress non-homogeneity phenomenon caused；The secondary objective of the present invention is open a kind of air grid swing mechanism.
Description
Technical field
The present invention relates to a kind of method eliminating glass wind speckle, especially by swinging the method that air grid eliminates the wind speckle formed on safety glass, and a kind of air grid swing mechanism.
Background technology
Annealing furnace toughening process can leave stress pattern (being commonly called as wind speckle) on glass, safety glass wind speckle is as an index of presentation quality, increasingly paid close attention to by people, for making wind speckle alleviate as far as possible, the sector technical staff takes various ways, such as use accelerate glass come out of the stove speed, optimize air holes layout, air grid teeter etc..But, the formation of wind speckle is complicated, except plant width direction needs to consider to form uniform cooling, it is often more important that also to consider to eliminate the formation of wind speckle along device length direction.Up to the present, the wind speckle of annealing furnace remains a flaw of safety glass, and people wait in expectation can more preferable wind speckle reduction technology, and the outward appearance making safety glass is more preferable.
Summary of the invention
In order to weaken the formation of wind speckle, the principle that we are formed from wind speckle, make glass wind-engaging cooling procedure the most uniformly, do not form strong and weak uneven cooling point.According to experimentation, being formed at of wind speckle largely stops relevant with glass in air grid, because, general annealing furnace air grid is limited in the area coverage of device length direction (glass conveying direction), and it is a process swinging mobile blowing along device length direction that glass cools down in air grid.When glass is in the moment of backswing, air grid tuyere is temporary transient geo-stationary relative to glass, at this, tuyere will be more than elsewhere in the wind-engaging region that glass surface is corresponding 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 not be respectively formed heavier wind speckle because of wind-engaging in the moment of geo-stationary.To this end, the primary and foremost purpose of the present invention is a kind of method disclosing wind speckle eliminating and being formed when glass swinging stops, in the moment of glass backswing, by the relative motion of air grid, eliminates glass and stop the Stress non-homogeneity phenomenon caused；The secondary objective of the present invention is open a kind of air grid swing mechanism.
To achieve these goals, a kind of method eliminating glass wind speckle of the present invention, some air grids it are provided with above and below rollgang, described air grid is uniform along glass conveying direction, form a blowing coverage, in cooling procedure, described rollgang drives glass to move back and forth along glass conveying direction in described blowing coverage；When the moving direction of described glass changes, mobile described air grid so that it is produce relative motion with glass on glass conveying direction.
Further, the speed of described air grid is equal with glass speed in reciprocating movement.
A kind of air grid swing mechanism, including rollgang, some air grids it are provided with above and below described rollgang, described air grid is uniform along glass conveying direction, form a blowing coverage, in cooling procedure, described rollgang drives glass to move back and forth along glass conveying direction in described blowing coverage；Air grid is movable, connecting to have on air grid to promote air grid to move forward and backward drive mechanism along glass conveying direction, described drive mechanism connects the actuating unit of its offer power promising, described air grid swing mechanism also includes speed detector, described speed detector is for detecting the speed of glass, and when glass conveying direction changes, send signal to drive mechanism.
Further, the speed of described air grid is equal with glass speed in reciprocating movement.
Further, described actuating unit is reducing motor, and described drive mechanism is the crank being connected on reducing motor and the connecting rod being connected with described crank, and described connecting rod is connected on described air grid.
The present invention, by studying the formation of wind speckle, avoids glass and air grid geo-stationary, especially when glass backswing as far as possible, glass meeting geo-stationary, makes air grid relative to glass motion, and the speed of the movement velocity of air grid front glass therewith is consistent, ensure that the wind-engaging on glass is uniform as far as possible, reduce the formation of wind speckle.
Accompanying drawing explanation
Fig. 1 is the structural representation of air grid swing mechanism of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings, the detailed description of the invention of the present invention is elaborated.
Embodiment 1
A kind of method eliminating glass wind speckle, being provided with some air grids above and below rollgang, air grid is uniform along glass conveying direction, forms a blowing coverage, in cooling procedure, rollgang drives glass to move back and forth along glass conveying direction in blowing coverage；When the moving direction of glass changes, mobile air grid so that it is produce relative motion with glass on glass conveying direction.When glass changes moving direction, still ensure that between air grid and glass, there is relative motion, will not stop at glass surface, effectively alleviate the formation of wind speckle.The translational speed of air grid is equal with glass speed in reciprocating movement.Glass is made to remain the constant relative velocity with air grid in reciprocating overall process, more uniform by air cooling, promote the effect reducing wind speckle further.
Embodiment 2
As shown in Figure 1, a kind of air grid swing mechanism, including rollgang 1, some air grids 2 it are provided with above and below rollgang 1, air grid 2 is uniform along glass 3 conveying direction, forming a blowing coverage, in cooling procedure, rollgang 1 drives glass 3 to move back and forth along glass 3 conveying direction in blowing coverage；Air grid 2 is movable, connecting to have on air grid 2 to promote air grid 2 to move forward and backward drive mechanism along glass 3 conveying direction, drive mechanism connects the actuating unit of its offer power promising, air grid 2 swing mechanism also includes speed detector (not shown), speed detector is for detecting the speed of glass 3, and when glass 3 conveying direction changes, send signal to drive mechanism.The translational speed of air grid is equal with glass speed in reciprocating movement.In the present embodiment, actuating unit is preferably reducing motor 6, the concrete structure of drive mechanism is the crank 5 being connected on reducing motor 6 and the connecting rod 4 being connected with crank 5, connecting rod 4 is connected on air grid 2, reducing motor 6 drives crank 5 to rotate, crank 5 drivening rod 4 moves, and then promotes air grid 2 to move.
Above-mentioned example is only intended to the present invention is described, embodiments of the present invention are not limited to these examples, and what those skilled in the art were made meets the various detailed description of the invention of inventive concept all within protection scope of the present invention.
