Description

A glass plate root adjustment control device at the tin bath entrance Technical Field

[0001] The invention relates to the field of float glass manufacturing, and in particular to a glass plate root regulating and controlling device at a tin bath inlet. Background Art

[0002] Float glass boasts excellent flatness and optical properties, along with a very uniform thickness. It is widely used in fields such as architecture, automobiles, and precision electronics, playing a vital role in promoting social and economic development and improving people's quality of life. The float glass production process is completed in a tin bath filled with protective gas. Molten glass flows continuously from a tank kiln into the tin bath, where it floats on the surface of the bath. Under the influence of gravity and surface tension, the glass spreads and flattens on the surface, forming a glass sheet. After cooling and hardening, it is removed from the tin bath and then annealed and cut to form transparent, colorless flat glass.

[0003] When using the traditional float method to manufacture glass, the molten glass enters the tin bath through the runner and lip bricks. Usually, fixed edge bricks (also known as eight-shaped bricks) of a certain length are set on both sides of the tin bath entrance. The fixed edge bricks are set close to the lip bricks and fixed by fixing rods, as shown in Figure 1. When the molten glass falls from the runner and lip bricks to the surface of the tin bath, it can immediately contact the fixed edge bricks. The fixed edge bricks are used to control the angle of the molten glass spreading, thereby manufacturing glass of different tonnages and specifications. At the same time, the fixed edge bricks can also fix the position of the root of the glass plate, so that the root of the glass plate will not deviate when the glass is thinned. The tin bath side walls on both sides can limit the molten glass from flowing out of the tin bath.

[0004] However, in the traditional method, the central angle corresponding to the fixed edge bricks on both sides is a fixed angle, which cannot be adjusted again after the initial setting. When producing glass of different tonnages and specifications, the fixed edge bricks need to be replaced frequently, which seriously affects the company's production efficiency. At the same time, it is difficult to meet the current multi-variety, small-batch manufacturing needs and the process requirements under different production conditions.

[0005] Summary of the Invention

[0007] To achieve the above-mentioned purpose, the present invention provides a glass plate root adjustment and control device at the tin bath entrance, wherein both sides of the tin bath entrance have tin bath side walls, and the glass plate root adjustment and control device includes two fixed edge bricks symmetrically arranged along the center line of the tin bath entrance, one end of the fixed edge brick is set at the tin bath entrance, and also includes a movable extension brick and an adjustment mechanism. The two fixed edge bricks are respectively hinged with a movable extension brick at one end away from the tin bath entrance, and the two movable extension bricks are symmetrically arranged along the center line of the tin bath entrance. The adjustment mechanism is connected to the movable extension brick, can adjust the rotation of the movable extension brick and change the distance between the movable extension brick and the center line of the tin bath entrance, and can stabilize the position of the movable extension brick.

[0008] Furthermore, one end of the fixed edge brick is provided with an arc-shaped depression, and one end of the movable extension brick is provided with an arc-shaped protrusion. The arc-shaped protrusion of the movable extension brick can be installed in the arc-shaped depression of the fixed edge brick, so that the movable extension brick can rotate relatively around the fixed edge brick.

[0009] Furthermore, the adjustment mechanism includes a limiting pressure rod and a locking structure, one end of the limiting pressure rod is hinged to the movable extension brick, and the other end passes through the side wall of the tin bath, and the limiting pressure rod can move inward or outward relative to the side wall of the tin bath, and the locking structure can fix the position of the limiting pressure rod.

[0010] Furthermore, the regulating mechanism has two or more limiting pressure rods.

[0011] Furthermore, the interior of the limiting pressure rod is a hollow structure, and a water cooling structure is also provided in the inner cavity of the limiting pressure rod.

[0012] Furthermore, the angle between the fixed edge bricks on both sides is an acute angle.

[0013] Furthermore, it also includes a fixing rod for fixing and installing the fixed edge bricks, one end of the fixing rod is fixedly connected to the fixed edge bricks, and the other end is fixed to the side wall of the tin bath.

[0014] As described above, the glass plate root adjustment control device at the tin bath inlet of the present invention has the following beneficial effects:

[0032] Referring to Figures 2 to 3, the present invention provides a glass plate root adjustment and control device at the entrance of a tin bath, wherein both sides of the entrance of the tin bath 8 are provided with tin bath side walls 4, and the glass plate root adjustment and control device includes two fixed edge bricks 2 symmetrically arranged along the center line of the tin bath entrance, one end of the fixed edge brick 2 is set at the entrance of the tin bath, and also includes a movable extension brick 1 and an adjustment mechanism 3. The two fixed edge bricks 2 are respectively hinged to one end of a movable extension brick 1 away from the tin bath entrance, and the two movable extension bricks 1 are symmetrically arranged along the center line of the tin bath entrance, one end of the adjustment mechanism 3 is connected to the movable extension brick 1, and the other end passes through the tin bath side wall 4, and can adjust the movable extension brick 1 away from the tin bath side wall 4, so that the movable extension brick 1 rotates relatively around the fixed edge brick 2, and changes the distance between the movable extension brick 1 and the center line of the tin bath entrance, thereby changing the opening angle of the movable extension brick 1 and stabilizing the position of the movable extension brick 1.

[0033] The basic working principle of the glass plate root adjustment control device involved in the present invention is: when the molten glass liquid flows through the tin bath inlet, the opening angle of the movable extension brick 1 can be changed through the adjustment mechanism 3 at the tin bath side wall 4, and the fixed edge brick 2 provides support. As the opening angle of the movable extension brick 1 changes, the spreading angle of the glass plate root flowing through the movable extension brick 1 changes, thereby meeting the process requirements of different production conditions and the current multi-variety and small batch manufacturing needs. At the same time, it also avoids the frequent replacement of fixed edge bricks and improves production efficiency.

[0034] 2 to 3 , the present invention will be further described below using a specific embodiment:

[0035] In this embodiment, referring to Figure 3, as a preferred design, one end of the fixed edge brick 2 is provided with an arc-shaped recess 201, and one end of the movable extension brick 1 is provided with an arc-shaped protrusion 101. The arc-shaped protrusion 101 of the movable extension brick 1 can be installed in the arc-shaped recess 201 of the fixed edge brick 2. The arc-shaped recess 201 and the arc-shaped protrusion 101 are preferably arc-shaped, and the two are concentric, so that the movable extension brick 1 can rotate relative to the fixed edge brick 2, and can ensure that the movable extension brick 1 can rotate flexibly without separating from the fixed edge brick 2. During the rotation of the movable extension brick 1, the gap between the arc-shaped protrusion 101 and the arc-shaped recess 201 is very small, so as to prevent the molten glass from flowing into the gap between the fixed edge brick 2 and the movable extension brick 1.

[0036] In this embodiment, referring to FIG2 , as a preferred design, the adjustment mechanism 3 includes a limiting pressure rod and a locking structure. One end of the limiting pressure rod is hinged to the movable extension brick 1, and the other end passes through the tin bath side wall 4. The limiting pressure rod can move inward or outward relative to the tin bath side wall 4. By pushing the limiting pressure rod inward or pulling the limiting pressure rod outward, the rotation of the movable extension brick 1 can be adjusted. The locking structure can fix the position of the limiting pressure rod, so that after adjusting the opening angle of the movable extension brick 1, it can be temporarily fixed, which can reduce manual labor.

[0037] In this embodiment, referring to FIG. 2 , as a preferred design, the adjusting mechanism 3 has two or more limiting pressure rods, which can improve the adjustability of the movable extension brick 1 .

[0038] In this embodiment, referring to FIG2 , as a preferred design, the interior of the limiting pressure rod is a hollow structure, and a water cooling structure is also provided in the inner cavity of the limiting pressure rod, which can avoid deformation of the limiting pressure rod due to high temperature when used for a long time and extend its service life.

[0039] In this embodiment, referring to FIG. 2 , as a preferred design, the angle between the fixed edge bricks 2 on both sides is an acute angle, which can stabilize the base of the glass plate and prevent the base of the glass plate from swinging or deflecting left and right.

[0040] In this embodiment, referring to FIG2 , as a preferred design, a fixing rod 7 for fixing and installing the fixed edge brick 2 is further included. One end of the fixing rod 7 is fixedly connected to the fixed edge brick 2, and the other end is fixed to the side wall 4 of the tin bath, which can improve the stability of the fixed edge brick 2, thereby fixing the position of the root of the glass plate.

[0041] As can be seen from the above, the glass plate root adjustment control device of the present invention has the following beneficial effects:

[0042] By providing a movable extension brick 1 and an adjustment mechanism 3, the opening angle of the movable extension brick 1 can be changed by pushing the adjustment mechanism 3 inward or pulling the adjustment mechanism 3 outward at the side wall of the tin bath, thereby being able to flexibly change the spreading angle of the glass plate roots flowing through the movable extension brick, meeting the process requirements of different production conditions and the current multi-variety, small-batch manufacturing needs. At the same time, it also avoids the frequent replacement of fixed edge bricks and improves production efficiency.

[0043] In summary, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0044] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
