From fig. 1 and the above description, the person skilled in the art will understand that the rail beam 17 is both a load-bearing part of the edge roller and a rail part of the edge roller into and out of the tin bath. Further, the track beams 17 span the top of the tin bath and are fixed on the tin channel structure or supported on the ground by upright posts at both ends and are parallel to the horizontal plane. By slidably connecting the power car 16 and the follower car 10 with the track beam 17, all the mechanisms of the edge roller can be combined into a whole, so that the freedom degree movement required by the process of pulling Bian Jigong can be realized.
Further, it will be understood by those skilled in the art that the horizontal swing mechanism 6 is provided at an upper portion of the rear end of the profiled beam 9. Preferably, in the vertical direction, the distance from the front rotation point mechanism 7 to the edge pulling rod is greater than the distance from the horizontal swinging mechanism 6 to the edge pulling rod, that is, the front end of the special-shaped beam 9 is higher than the rear end of the special-shaped beam 9, so that the front rotation point mechanism 7 is closer to the track beam 17, and the special-shaped beam 9 is stable and prevented from swinging when swinging horizontally around the front rotation point mechanism 7, so that the front rotation point mechanism 7 and the engagement point are prevented from being deviated from being located on the same central line due to the position deviation of the front rotation point mechanism 7 and the engagement point in the horizontal swinging process.
FIG. 4 shows a flow chart of a float glass production method in which the projection of a forward rotation point coincides with an engagement point, according to the embodiment of the invention, the production method is characterized in that a glass ribbon floating on the liquid surface of a tin bath is pulled to advance by means of a edge roller of the edge roller, and the thickness and the width of glass forming are controlled by adjusting parameters such as the linear speed, the horizontal deflection angle, the plane inclination angle and the like of the edge roller. The edge rollers are symmetrically arranged on two sides of the tin bath in pairs.
In such an embodiment, first, step S101 is performed, in which the edge roller of the edge roller engages with the glass ribbon to form an engagement point, and the front rotation point mechanism and the engagement point have the same center line in the vertical direction. Specifically, in connection with the embodiments shown in fig. 1 to 3 described above, the edge roller 11 is controlled to be pushed down or lifted up by driving the vehicle body 8 to form a nip with the glass ribbon. In the initial state, the swing angle of the special-shaped beam 9 is zero, that is, the special-shaped beam 9 is parallel to the track beam 17, and the horizontal projection of the forward rotation point mechanism 7 coincides with the engagement point.
And then, step S102 is carried out, wherein the horizontal swinging mechanism drives the special-shaped beam to swing on the horizontal plane by taking the same central line as an axis when in operation, and the meshing point position is kept unchanged in the swinging process of the special-shaped beam. Specifically, when the horizontal swing angle of the edge roller is adjusted, that is, the horizontal swing mechanism 6 drives the special-shaped beam 9 to rotate around the same center line by a corresponding angle, the edge roller 11 swings coaxially with the special-shaped beam 9 in a horizontal plane, that is, the edge roller 11 also rotates around the same center line as a shaft. In such an embodiment, since the projection of the pronation point mechanism 7 coincides with the engagement point, the edge roller 11 and the pronation point mechanism 7 do not undergo relative displacement during rotation, that is, the engagement point is kept unchanged, so that when the profiled beam 9 swings horizontally by a certain angle, the edge roller 11 is pressed against the glass ribbon to greatly move to affect glass forming.
Specifically, referring to the embodiment shown in fig. 2, in the initial state, the special-shaped beam 9 is perpendicular to the tail beam 15, the tangent line of the edge roller 11 on the glass ribbon is parallel to the advancing direction of the glass ribbon, and a pair of edge rollers 11 are symmetrically located on two sides of the transverse section of the glass ribbon. When the profiled beam 9 drives the edge wheel 11 to rotate clockwise or anticlockwise by an angle beta relative to the advancing direction of the glass ribbon, a sine value of the speed of the edge wheel 11 on both sides is applied to the transverse traction force of the transverse section of the glass ribbon to both sides, so that the glass ribbon is widened and thinned along both sides of the tin bath, or a sine value of the speed of the edge wheel 11 on both sides is applied to the transverse traction force of the transverse section of the glass ribbon to the center, so that the glass ribbon is narrowed and thickened along the center of the tin bath. Those skilled in the art will appreciate that the larger the pivot angle β, the larger the lateral component, and the smaller the β, the smaller the lateral component. Further, the faster the edge wheel 11 rotates, the deeper the glass ribbon is pressed into, and the greater the traction force exerted on the glass ribbon, which will not be described in detail.
FIG. 5 shows a flow chart of a float glass production process in which the pronation point projection coincides with the bite point, in accordance with an embodiment of the present invention. In such an embodiment, the horizontal swing mechanism of the edge roller includes a swing car body, a swing motion motor, a guide bar arrangement, and a tail boom. In particular, the person skilled in the art can refer to the embodiments shown in fig. 1 and 2 described above.
Step S201 is first executed, where the edge roller of the edge roller engages with the glass ribbon to form an engagement point, and the front rotation point mechanism and the engagement point have the same center line along the vertical direction. Specifically, the person skilled in the art can refer to step S101 in the embodiment shown in fig. 4, which is not described herein.
Subsequently, step S202 is performed, where the swing motor drives the swing car body to slide along the tail boom, and specifically, referring to fig. 1 and 2, the swing motor 13 drives the swing car body 12 to perform a linear motion along the axial direction of the tail boom 15.
Further, through step S203, the swing car body deflects with respect to the special-shaped beam and drives the special-shaped beam to swing in a horizontal plane with the same center line as an axis. Specifically, the profiled beam 9 is linearly slid with respect to the guide bar device 14 in the axial direction of the guide bar device 14 by the above step S202. The swinging car body 12 rotates around a rotation center relative to the special-shaped beam 9, and the rotation center is the connection point of the swinging car body 12 and the special-shaped beam 9 so as to drive the special-shaped beam 9 to rotate in an arc with the same central line as an axis, thereby further driving the edge roller 11 to synchronously rotate around the same central line. Those skilled in the art understand that according to the process requirement, the swing motion of the special-shaped beam 9 can swing towards the left side of the original position or towards the right side of the original position, and the edge roller 11 is unchanged at the position of the biting point, and the swing angle can be correspondingly set according to the requirement of glass forming.
Further, a plurality of pairs of edge rollers are symmetrically arranged on two sides of the tin bath respectively, and glass strips in the tin bath are pulled by the edge rollers. Specifically, the swing direction and the swing angle of the horizontal swing mechanism 6 are adjusted to drive the edge roller 11 to rotate at the engagement point in situ to control the direction in which the edge roller pulls the glass ribbon, and further, the rotation speed of the edge roller 11 is controlled to control the width and the thickness of the glass ribbon, so that the glass ribbon is transferred to the next pair of edge rollers adjacently arranged, and the description is omitted here. Those skilled in the art understand that in such an embodiment, the plurality of tail beams of the plurality of edge rollers are independent of each other, and can move along the track beam along with the edge rollers to ensure that the center lines of the paired edge rollers are symmetrical, so that a bracket system of the edge rollers is omitted, the edge rollers are simple in structure, and the influence on glass forming quality and product service life caused by vibration of adjacent edge rollers due to insufficient rigidity of the brackets when the swing angle of one of the edge rollers is adjusted when the plurality of groups of edge rollers are hung on the mutually related brackets is avoided.
