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

The application provides a glass cutting frock, as shown in fig. 1 to 3, wherein, glass cutting frock includes:

a discharge hole for the glass ribbon 2 to flow downwards is arranged below the annealing furnace 1;

a cutting mechanism 3 arranged below the discharge port and comprising a cutting tool 31 and a supporting anvil plate 32 respectively abutted against both sides of the glass ribbon 2, the cutting tool 31 and the supporting anvil plate 32 being aligned in the thickness direction B, the cutting tool 31 being capable of scribing a cutting line 21 extending up and down on the glass ribbon 2 when the glass ribbon 2 flows down; and

the breaking mechanism 4 includes a first abutting piece 41 and a second abutting piece 42 which are offset in the thickness direction B, and the first abutting piece 41 and the second abutting piece 42 are provided on both sides of the cutting line 21 so as to be pressed against the surface of the glass ribbon 2.

The glass cutting frock in this application mainly cuts glass ribbon 2 in step at the in-process of overflow downdraw method production ultra-thin flexible glass ribbon 2, specifically, after the overflow launder of glass liquid follow funnel flows, can get into cooling in order to form laminar glass ribbon 2 in annealing stove 1, and laminar glass ribbon 2 can flow out and pass through cutting mechanism 3 and lobe structure in proper order from the discharge gate of annealing stove 1 again, because cutting mechanism 3 includes cutting tool 31 and the support chopping board 32 of alignment along thickness direction B, after glass ribbon 2 flows to cutting tool 31 and support chopping board 32 through the guide, the continued downflow of glass ribbon 2 can make cutting tool 31 draw a cutting line 21 that extends from top to bottom on glass ribbon 2, and through the adaptive adjustment cutting tool 31 arrangement position, can make cutting line 21 just in the boundary department of passing material district and bait district, after cutting line 21 is gone out on glass ribbon 2, continue to guide glass ribbon 2 flows to between first abutment member 41 and the second abutment member 42, because first abutment member 41 and second abutment member 42 are in thickness direction B aligned cutting tool 31 and support chopping board 32, thereby can make continuous cutting ribbon offset strip 2 cut dislocation along the cutting line 21, thereby continuous cutting ribbon can be realized to the continuous cutting strip dislocation region 2. To sum up, glass cutting frock in this application can carry out synchronous cutting to glass ribbon 2 when glass ribbon 2 drop-down is drawn, when glass ribbon 2 drop-down is accomplished, glass ribbon 2 also synchronous cutting is accomplished, not only avoided the secondary of glass ribbon 2 to cut processing, the production process has been simplified, low production cost, glass ribbon 2 of this state can directly carry out crooked package, make things convenient for workman's operation simultaneously, moreover, glass cutting frock in this application can realize glass ribbon 2's automatic continuous cutting and lobe of a leaf under the prerequisite of need not with the help of extra actuating mechanism, automatic continuous cutting and automatic continuous cutting lobe of a leaf's realization are all with the help of overflow downdraw from the glass ribbon 2 downstream process of area, thereby can reach the purpose of simplifying glass production facility.

If the glass ribbon 2 is put and cut after the glass ribbon 2 is pulled down, the bait with a thicker thickness on the glass ribbon 2 can easily break the bait part of the glass ribbon 2 in the process of taking and putting, and the breakage of the bait can easily lead to the crack extending to the qualified material area, so that the whole glass ribbon 2 becomes waste. Therefore, in order to avoid the occurrence of the situation, the application combines the cutting process of the glass ribbon 2 with the downstream process of the glass, and the glass ribbon 2 is synchronously cut by the glass cutting tool when the glass ribbon 2 is pulled down, so that the glass cutting tool synchronously completes the cutting of the glass ribbon 2, and the subsequent cutting step is avoided. The purpose of the support anvil 32 is to: the cutting pressure of the cutting tool 31 forces the flexible glass ribbon 2 to be deformed under pressure, resulting in bending of the cutting wire 21 or insufficient cutting force, while the smooth cutting of the cutting tool 31 can be ensured by supporting the cutting board 32 on the other side. The cutting mechanism 3 may also take other forms, such as conventional laser cutting.

As shown in fig. 1 to 3, in the embodiment of the present application, one of the arrangement forms of the first abutment 41 and the second abutment 42 may be: the first abutting member 41 includes a first clamping portion 411 and a second clamping portion 412 clamped on both sides of the glass ribbon 2, the second abutting 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 misalignment height in the thickness direction B, the second clamping portion 412 and the fourth clamping portion 422 on the same side have a second misalignment height in the thickness direction B, and the first misalignment height and the second misalignment height are equal. Specifically, taking the example that the first abutting member 41 is disposed on the outer side of the cutting line 21, the first clamping portion 411 and the second clamping portion 412 are disposed on the outer side of the cutting line 21 and clamp two sides of the glass ribbon 2, the third clamping portion 421 and the fourth clamping portion 422 are disposed on the inner side of the cutting line 21 and clamp two sides of the glass ribbon 2, due to the dislocation height of the clamping portions on the same side of the glass ribbon 2, the dislocation height can force a shearing force along the thickness direction B to be generated between the inner side and the outer side of the cutting line 21, and the shearing force can force the bait region of the glass ribbon 2 to automatically split and fall along the cutting line 21, namely, the stripping separation of the bait region can be realized by the two clamping portions on the same side of the glass ribbon 2, wherein the clamping portions are also disposed on the other side of the glass ribbon 2 to clamp two sides of the glass ribbon 2, the purpose of: the clamping part on one side can support the glass ribbon 2 when the glass ribbon 2 is pressed, so that the glass ribbon 2 is better stressed when being cracked. It should be noted that, since the glass ribbon 2 has a certain flexibility, the first abutment member 41 and the second abutment member 42 need to be disposed as close to the cutting line 21 as possible in order to ensure successful breaking. Of course, there are other arrangements of the first abutting member 41 and the second abutting member 42, for example, the first abutting member 41 and the second abutting member 42 are separately disposed at two sides of the cutting line 21 and respectively abut against two sides of the glass ribbon 2, and the first abutting member 41 and the second abutting member 42 at two sides are clamped in a dislocation manner along the approaching direction of the two sides, so that the automatic breaking effect can be achieved.

By setting the clamping part as a roller, the resistance of the clamping part to the downflow of the glass ribbon 2 can be reduced, and the situation that the downflow cannot be caused by overlarge resistance of the glass ribbon 2 is avoided. Of course, in actual production, the glass ribbon 2 is typically downstream with a pulling mechanism attached at the head end to pull the glass ribbon 2 down.

As shown in fig. 1 and 2, 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 that are provided on both sides in the width direction a of the ribbon body 22, the number of cutting tools 31 is plural, 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. The glass liquid flows out from the overflow groove, and in the cooling forming process in the annealing furnace 1, the baits with thicker thickness are easy to appear at the two ends of the width direction A, so that when in cutting, two sides of the glass ribbon 2 are required to be cut off, at least two cutting tools 31 and two groups of first abutting pieces 41 and second abutting pieces 42 are arranged, the minimum cutting requirement of cutting two sides of the glass ribbon 2 can be met, namely, at least one group of cutting tools 31 and at least one group of first abutting pieces 41 and second abutting pieces 42 are respectively arranged at two sides of the ribbon body 22, and automatic cutting and peeling of the first bait part 23 and the second bait part 24 are realized.
