Description

Technical Field

[0001] The present application belongs to the technical field of glass production, and specifically relates to a glass cutting tool. Background Art

[0002] With the development of foldable screen mobile phones, flexible display screens have gradually become popular in the market, and display glass cover plates are gradually developing in the direction of being thin and flexible. The existing ultra-thin flexible glass production methods generally include float method, overflow down-pull method, etc., and the overflow down-pull method has the advantages of one-time molding and no pollution on the glass surface, so it is more widely used. Among them, the process steps of the overflow down-pull method to produce ultra-thin flexible glass are generally: pour the glass liquid of special material into the funnel, and then control the glass liquid to flow from top to bottom along the overflow trough of the funnel, and then anneal and cool the outflowing glass to obtain an ultra-thin flexible glass ribbon. In order to facilitate the transportation of the flexible glass ribbon, the glass ribbon needs to be bent and rolled. However, due to the inherent characteristics of the production process, the glass ribbon flowing out of the overflow trough will inevitably produce thick bait at its edge, causing the glass to be very easy to break when bent and rolled. If the process step of manually cutting the bait is added after the glass ribbon is formed, not only does it need to add an additional set of cutting equipment, which increases the complexity of the production process, but it is also very easy to damage the glass ribbon when placing the cut glass ribbon manually. Therefore, how to cut the bait of glass ribbon is an important problem that needs to be solved urgently.

[0035] The specific embodiments of the present application are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0036] The glass cutting tool of the present application is described below with reference to the accompanying drawings.

[0037] The present application provides a glass cutting tool, such as Figures 1 to 3 As shown, the glass cutting tool comprises:

[0038] The annealing furnace 1 has a discharge port at the bottom for the glass ribbon 2 to flow down;

[0039] A cutting mechanism 3 is disposed below the discharge port and includes a cutting tool 31 and a supporting anvil 32 respectively abutting against two sides of the glass ribbon 2. The cutting tool 31 and the supporting anvil 32 are aligned in the thickness direction B. The cutting tool 31 can draw a cutting line 21 extending up and down on the glass ribbon 2 when the glass ribbon 2 flows down; and

[0040] The breaking mechanism 4 includes a first abutment member 41 and a second abutment member 42 which are offset in the thickness direction B. The first abutment member 41 and the second abutment member 42 are respectively arranged on both sides of the cutting line 21 and pressed against the surface of the glass ribbon 2 respectively.

[0041] The glass cutting tool in the present application is mainly used to synchronously cut the glass ribbon 2 during the process of producing ultra-thin flexible glass ribbon 2 by overflow down-drawing method. Specifically, after the glass liquid flows out from the overflow groove of the funnel, it will enter the annealing furnace 1 to cool to form a thin sheet of glass ribbon 2, and the thin sheet of glass ribbon 2 will flow out from the discharge port of the annealing furnace 1 and pass through the cutting mechanism 3 and the splitting structure in sequence. Since the cutting mechanism 3 includes a cutting tool 31 and a supporting anvil 32 aligned along the thickness direction B, when the glass ribbon 2 flows between the cutting tool 31 and the supporting anvil 32 through the guidance, the continued downward flow of the glass ribbon 2 will cause the cutting tool 31 to scratch a line on the glass ribbon 2. A cutting line 21 is extended vertically, and by adaptively adjusting the arrangement position of the cutting tool 31, the cutting line 21 can be located exactly at the boundary between the qualified material area and the bait material area. After the cutting line 21 is drawn on the glass ribbon 2, the glass ribbon 2 is continuously guided to flow between the first abutment 41 and the second abutment 42. Since the first abutment 41 and the second abutment 42 are misaligned in the thickness direction B, the first abutment 41 and the second abutment 42 will respectively perform misaligned extrusion on the glass ribbon 2 from both sides of the cutting line 21, so that the bait material area is cracked and peeled off along the cutting line 21, and the continuous flow of the glass ribbon 2 will enable the glass ribbon 2 to achieve continuous cutting and waste peeling. In summary, the glass cutting tool in the present application can synchronously cut the glass ribbon 2 while the glass ribbon 2 is being pulled down. When the glass ribbon 2 is pulled down, the glass ribbon 2 is also synchronously cut. This not only avoids the secondary cutting process of the glass ribbon 2, simplifies the production process, and reduces production costs, but also the glass ribbon 2 in this state can be directly bent and rolled, which is convenient for workers to operate. Furthermore, the glass cutting tool in the present application can realize automatic continuous cutting and splitting of the glass ribbon 2 without the aid of an additional driving mechanism. The automatic continuous cutting and automatic continuous cutting and splitting are both realized by means of the downstream process of the glass ribbon 2 provided by the overflow down-drawing method, thereby achieving the purpose of simplifying the glass production equipment.

[0042] It should be noted that if the glass ribbon 2 is placed and cut after the glass ribbon 2 is pulled down, the glass ribbon 2 at this time will be easy to cause the bait to partially break during the process of taking and placing the glass ribbon 2 due to the presence of thick bait, and the breakage of the bait will easily cause the cracks to extend to the qualified material area, causing the entire glass ribbon 2 to become waste. Therefore, in order to avoid the occurrence of the above situation, the present application combines the cutting process of the glass ribbon 2 with the downstream process of the glass. While the glass ribbon 2 is flowing down, the glass cutting tool will synchronously cut the glass ribbon 2. When the glass ribbon 2 is pulled down, the glass cutting tool also synchronously completes the cutting of the glass ribbon 2, avoiding subsequent cutting steps. The purpose of setting the support anvil 32 is that the cutting pressure of the cutting tool 31 will force the flexible glass ribbon 2 to be compressed and deformed, resulting in the bending of the cutting line 21 or insufficient cutting force, and by supporting the support anvil 32 on the other side, the smooth cutting of the cutting tool 31 can be guaranteed. The above-mentioned cutting mechanism 3 can also be in other forms, such as common laser cutting.

[0043] like Figures 1 to 3As shown, in an embodiment of the present application, one arrangement form of the first abutment member 41 and the second abutment member 42 can be: the first abutment member 41 includes a first clamping portion 411 and a second clamping portion 412 clamped on both sides of the glass ribbon 2, and the second abutment member 42 includes a third clamping portion 421 and a fourth clamping portion 422 clamped on both sides of the glass ribbon 2, the first clamping portion 411 and the third clamping portion 421 on the same side have a first offset height in the thickness direction B, and the second clamping portion 412 and the fourth clamping portion 422 on the same side have a second offset height in the thickness direction B, and the first offset height and the second offset height are equal. Specifically, taking the first abutment member 41 being arranged on the outer side of the cutting line 21 as an example, the first clamping portion 411 and the second clamping portion 412 are arranged on the outer side of the cutting line 21 and clamp the two sides of the glass ribbon 2, and the third clamping portion 421 and the fourth clamping portion 422 are arranged on the inner side of the cutting line 21 and clamp the two sides of the glass ribbon 2. Since there is an offset height of the clamping portions on the same side of the glass ribbon 2, the offset height will force a shear force along the thickness direction B to be generated between the inner and outer sides of the cutting line 21, and the shear force will compel the bait area of ​​the glass ribbon 2 to automatically break and fall off along the cutting line 21, that is, the two clamping portions offset on the same side can realize the peeling and separation of the bait area, wherein a clamping portion is also provided on the other side of the glass ribbon 2 to clamp the glass ribbon 2 on both sides. The purpose is that when the clamping portion on one side presses the glass ribbon 2, the clamping portion on the other side can support the glass ribbon 2, thereby ensuring that the glass ribbon 2 is better stressed when breaking. It should be noted that, since the glass ribbon 2 has a certain flexibility, in order to ensure successful splitting, the first abutment member 41 and the second abutment member 42 need to be arranged as close to the cutting line 21 as possible. Of course, there are other arrangements of the first abutment member 41 and the second abutment member 42, such as the first abutment member 41 and the second abutment member 42 are arranged on both sides of the cutting line 21 and respectively abut against both sides of the glass ribbon 2, and the first abutment member 41 and the second abutment member 42 on both sides are staggered and clamped in the direction in which the two abutment members are close to each other, so that the effect of automatic splitting can also be achieved.

[0044] It should be noted that the two sides of the glass ribbon 2 mentioned above refer to the two sides in the thickness direction B of the glass ribbon 2 , and the two sides of the cutting line 21 refer to the two sides in the width direction A.

[0045] like Figures 1 to 3 As shown, in the embodiment of the present application, the first clamping part 411, the second clamping part 412, the third clamping part 421 and the fourth clamping part 422 are all rotating wheels, and the extension direction of the central axis of the wheels is parallel to the width direction A of the glass ribbon 2. By setting the clamping part as a roller, the resistance of the clamping part to the glass ribbon 2 flowing downward can be reduced, and the situation that the glass ribbon 2 cannot flow downward due to excessive resistance can be avoided. Of course, in actual production, when the glass ribbon 2 flows downward, a traction mechanism is generally connected to the head end to pull the glass ribbon 2 downward.

[0046] like Figure 1 and Figure 2 As shown, in the embodiment of the present application, the glass ribbon 2 includes a ribbon body 22 and a first bait portion 23 and a second bait portion 24 respectively arranged on both sides of the ribbon body 22 in the width direction A. There are multiple cutting tools 31, at least one cutting tool 31 abuts against the junction of the ribbon body 22 and the first bait portion 23, and at least one cutting tool 31 abuts against the junction of the ribbon body 22 and the second bait portion 24. When the glass liquid flows out of the overflow trough, during the cooling and forming process in the annealing furnace 1, thick bait is very likely to appear at both ends of the width direction A. Therefore, when cutting, both sides of the glass ribbon 2 need to be cut off. The minimum cutting requirement of cutting both sides of the glass ribbon 2 can be met by providing at least two cutting tools 31 and two sets of first abutting members 41 and second abutting members 42, that is, by providing at least one set of cutting tools 31 and at least one set of first abutting members 41 and second abutting members 42 on both sides of the ribbon body 22, the first bait portion 23 and the second bait portion 24 can be automatically cut and peeled off.

[0047] like Figure 1 and Figure 2 As shown, in the embodiment of the present application, the supporting anvil 32 is also a rotating roller. The supporting anvil 32 is set as a roller to reduce the resistance of the glass ribbon 2 when it flows.

[0048] like Figure 1 and Figure 2 As shown, in the embodiment of the present application, the glass cutting tool also includes a guide wheel group 5 arranged between the discharge port and the cutting mechanism 3, and the guide wheel group 5 includes a first guide wheel 51 and a second guide wheel 52 aligned in the thickness direction B, and the first guide wheel 51 and the second guide wheel 52 are rotatably clamped on both sides of the glass ribbon 2 and the extension direction of the central axis of rotation is parallel to the width direction A of the glass ribbon 2. Since the glass cutting tool in the present application is mainly used in the production of ultra-thin flexible glass, and the ultra-thin flexible glass will inevitably shake and bend when flowing after flowing out of the annealing furnace 1 due to its light weight, and the shaking and bending of the glass ribbon 2 is likely to cause the cutting line 21 of the cutting tool 31 to bend during cutting, resulting in unqualified cutting, and the present application clamps and limits the glass ribbon 2 by arranging the first guide wheel 51 and the second guide wheel 52 between the discharge port and the cutting mechanism 3, thereby avoiding the bending and shaking of the glass and ensuring the stability of the entire marking and splitting process. Among them, since the thickness of the middle belt body 22 is uniform, while the thickness of the bait part varies greatly, it is preferred that the first guide wheel 51 and the second guide wheel 52 are clamped against the belt body 22, and the first guide wheel 51 and the second guide wheel 52 are rotated to reduce the resistance of the glass ribbon 2 flowing downstream.

[0049] like Figure 1 and Figure 2As shown, in the embodiment of the present application, there are multiple guide wheel groups 5, and multiple guide wheel groups 5 are clamped against the inner side of the cutting line 21. By providing multiple guide wheel groups 5, the flow stability of the glass ribbon 2 near the discharge port can be further increased.

[0050] like Figure 1 and Figure 2 As shown, in the embodiment of the present application, the glass cutting tool further includes a recovery funnel 6, which is arranged below the splitting mechanism 4 and the funnel opening is aligned with the discharge port. By arranging the recovery funnel 6 below the splitting mechanism 4, the peeled and separated waste can automatically fall into the recovery hopper, thereby facilitating the recycling and reuse of the waste.

[0051] like Figure 1 and Figure 2 As shown, in the embodiment of the present application, a waste outlet is provided below the recovery hopper 6, and the glass cutting tool further comprises a waste collection box 7 arranged below the waste outlet. After the waste falls into the recovery hopper, it will fall into the waste collection box 7 through the waste outlet below, and the waste collection box 7 is movably provided. When the waste collection box 7 is filled with waste glass, the waste collection box 7 can be moved and transported to the melting furnace for remelting.

[0052] like Figure 1 and Figure 2 As shown, in an embodiment of the present application, the glass cutting tool also includes a plurality of movable mounting seats that can reciprocate along the thickness direction B, and the cutting tool 31, the supporting anvil 32, the first abutment 41 and the second abutment 42 are mounted on the plurality of movable mounting seats in a one-to-one correspondence. By arranging the above-mentioned cutting tool 31, the supporting anvil 32, the first abutment 41 and the second abutment 42 and other components that are in direct contact with the glass on the movable mounting seat, these components can adjust the spacing in the thickness direction B and avoid, so as to facilitate the guidance and downflow of the glass ribbon. For example, during glass production, there may be a sudden abnormal thickness of the glass ribbon 2, and by driving the corresponding movable mounting seat to move and avoid, the smooth flow of these abnormal glasses can be ensured, and the occurrence of "stuck machine" can be avoided. Among them, there are many ways to realize the movement of the movable mounting seat, such as a reciprocating cylinder, a slide rail slot, etc. Since the arrangement form is more common, it is no longer described in detail in the specification.

[0053] In an embodiment of the present application, a guide member may be provided between the recovery funnel 6 and the splitting mechanism 4 , and the guide member may be a roller or a guide wheel. Through the guidance of the guide member, the flow of the belt body 22 may be diverted to prevent the belt body 22 from falling into the recovery funnel 6 .

[0054] It should be noted that in the existing glass cutting process, using a tool to cut glass generally involves first drawing a cutting line on the glass and then breaking the glass along the cutting line. The main function of the splitting mechanism 4 in this application is to break and peel off the bait area along the cutting line 21.
