[0034] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the convenience of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0036] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "above", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below", and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is lower than that of the second feature.

In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0038] As Figures 1 to 3 shown, in the prior art, the glass cutting device mainly includes a conveying mechanism, a cutting mechanism, and a edge-breaking mechanism. Among them, the conveying mechanism is used to move the glass, the cutting mechanism can form a cutting seam on the glass during the movement of the glass, and the edge-breaking mechanism can squeeze at least one side of both sides of the cutting seam to separate the glass along the cutting seam into a glass main body and a redundant edge part.

[0039] In the existing cutting mechanism, a cutting tool head and a longitudinal cutting pressure wheel are provided. The cutting tool head can cut and form a cutting seam on the glass during the movement of the glass, and the longitudinal cutting pressure wheel can press the glass when the cutting seam is formed to ensure the quality of the cutting seam. However, the inventor found that asFigure 2 As shown, since the longitudinal cutting pressure wheel is located on the side of the cutting tool head close to the glass edge, when the width of the redundant edge is narrow, it cannot achieve an effective and stable pressing effect, resulting in uneven and unstable pressure, poor cutting seam quality, and prone to problems such as burrs on the cutting surface and broken edges.

[0040] At the same time, the inventor found that, as Figure 3 shown, in the existing edge-breaking mechanism, due to the small contact area between the edge-breaking wheel and the glass, the pressure on the local part of the glass is relatively large, which also leads to problems such as burrs on the cutting surface and broken edges.

[0041] The present utility model provides a glass cutting device, aiming to solve the problems such as burrs on the cutting surface and broken edges that are prone to occur in the process of glass cutting in the prior art. The following introduces the glass packaging device provided by the present utility model according to the attached Figure 4 to the attached Figure 7 .

[0042] Specifically, referring to Figure 4 and Figure 5 shown, the glass cutting device provided by the present utility model also includes a conveying mechanism, a cutting mechanism, and an edge-breaking mechanism. Among them, the conveying mechanism includes a roller path 11, and the roller path 11 can convey the glass along a preset horizontal first direction. In practical applications, the roller path 11 is composed of a plurality of rollers arranged in parallel, and the rollers are driven by a motor to rotate, so as to achieve the stable conveying of the glass. The cutting mechanism includes the above-mentioned cutting tool head 31 and the longitudinal cutting pressure wheel 32, and can form a cutting seam extending along the horizontal first direction on the glass when the glass moves.

[0043] The edge-breaking mechanism includes at least two edge-breaking wheels 21. The at least two edge-breaking wheels 21 are arranged at equal intervals along the horizontal first direction. The edge-breaking wheels 21 are arranged at an adjustable distance from the roller path 11 in the vertical direction. The edge-breaking wheels 21 are used to apply pressure to the glass so that the glass breaks along the cutting seam.

[0044] In practical applications, the edge-breaking wheels 21 contact the redundant edge 102 of the glass through the bottom surface and apply pressure, so that the redundant edge 102 is separated from the glass product. Since a plurality of edge-breaking wheels 21 are provided, the pressure can be applied more evenly, and the risk of glass breakage caused by excessive single-point pressure can be reduced, thereby avoiding problems such as burrs on the cutting surface and broken edges after cutting.

[0045] Optionally, in this embodiment, as Figure 4 and Figure 5As shown in the figure, the edge-breaking mechanism includes a first bracket 22. Four edge-breaking wheels 21 are arranged on the first bracket 22 at equal intervals along the horizontal first direction. The first bracket 22 is arranged such that the distances between it and the roller path 11 are adjustable in the vertical direction, the horizontal first direction, and the horizontal second direction, and the horizontal second direction is perpendicular to the horizontal first direction. This design enables the position of the edge-breaking wheels 21 to be flexibly adjusted according to actual needs to adapt to glass products of different sizes. Of course, in some other embodiments, two, three, or more edge-breaking wheels 21 can also be provided, and the present utility model does not make specific limitations on this as long as the effect of reducing the pressure on the local part of the glass can be achieved.

[0046] Specifically, in this embodiment, the edge-breaking mechanism further includes a second bracket 26, a transverse slider 24, and a lead screw 25. The transverse slider 24 is slidably arranged on the second bracket 26 along the horizontal second direction. The first bracket 22 is fixedly installed on the transverse slider 24. The lead screw 25 passes through and is threadedly connected to the transverse slider 24, and the lead screw 25 can drive the transverse slider 24 to slide along the horizontal second direction. By rotating the lead screw 25, the transverse slider 24 can be driven to slide along the horizontal second direction, thereby driving the first bracket 22 and the edge-breaking wheels 21 to move horizontally. This design enables the edge-breaking wheels 21 to be precisely adjusted according to the position of the cut seam to ensure the accuracy of the edge-breaking operation.

[0047] As Figure 4 shown in the figure, a vertical height adjuster 23 is connected between the transverse slider 24 and the second bracket 26. The vertical height adjuster 23 is used to adjust the distance between the first bracket 22 and the roller path 11 in the vertical direction. The vertical height adjuster 23 can be selected from structures such as motors and cylinders, and according to the input command or the change in pressure, the first bracket 22 can be lowered or lifted to adjust the distance between the first bracket 22 and the roller path 11.

[0048] More specifically, in this embodiment, an adjusting wheel 29 is connected to the end of the lead screw 25. By means of the adjusting wheel 29, the lead screw 25 can be conveniently rotated to adjust the position of the edge-breaking wheels 21. Of course, in some other embodiments, driving members such as servo motors and cylinders can also be used to drive the lead screw 25 to rotate to achieve the adjustment of the position of the edge-breaking wheels 21, which also falls within the scope protected by the present utility model.

[0049] Continue to refer to Figure 5As shown, the edge-breaking mechanism further includes a third bracket 28 and a longitudinal slider 27. The longitudinal slider 27 is disposed on the third bracket 28 with adjustable position along the horizontal first direction, and the second bracket 26 is fixedly installed on the longitudinal slider 27. Therefore, the positions of the second bracket 26 and the first bracket 22 in the horizontal first direction can be changed by adjusting the position of the longitudinal slider 27, and in cooperation with the adjustment of the position of the transverse slider 24, the distance between the edge-breaking wheel 21 and the roller path 11 can be adjusted along both the horizontal first direction and the horizontal second direction.

[0050] Specifically, the third bracket 28 is provided with a longitudinal guide groove. The longitudinal slider 27 is slidably inserted through the longitudinal guide groove, and the longitudinal slider 27 is equipped with a locking nut for locking and fixing the longitudinal slider 27 to the third bracket 28. When position adjustment is required, by screwing out the locking nut, the longitudinal slider 27 can be slid along the longitudinal guide groove. After sliding to the preset position, by screwing in the locking nut, the locking nut and the longitudinal slider 27 clamp and fix the third bracket 28, and the relative fixation between the second bracket 26 and the third bracket 28 can be achieved.

[0051] As Figure 6 、 Figure 7 shown, in this embodiment, the longitudinal cutting pressure wheel 32 is disposed on the side of the cutting head 31 away from the glass edge. This design enables the cutting point of the cutting head 31 to be as close as possible to the glass edge, and enables the longitudinal cutting pressure wheel 32 to still have an effect of pressing and limiting the glass, ensuring the accuracy and quality of the cutting seam.

[0052] Specifically, the cutting mechanism includes a longitudinal cutting base 33, and the longitudinal cutting base 33 includes a first part 331, a second part 332, and a third part 333. Along the horizontal second direction, the second part 332 is connected to one end of the first part 331 away from the glass edge, the third part 333 is connected to one end of the first part 331 close to the glass edge, the longitudinal cutting pressure wheel 32 is located below the first part 331, the second part 332 is equipped with the longitudinal cutting pressure wheel 32, and the third part 333 is provided with an installation hole for installing the longitudinal cutting pressure wheel 32.

[0053] In the actual application process, since the longitudinal cutting pressure wheel 32 is disposed on the second part 332 and the second part 332 is farther from the glass edge than the longitudinal cutting pressure wheel 32, the longitudinal cutting pressure wheel 32 can be pressed against the inner side of the glass, that is, the glass body 101 part, enabling the width of the redundant edge part 102 to be reduced as much as possible, which is also beneficial to controlling the production cost of the glass.

[0054] At the same time, the third part 333 is provided with an installation hole for installing the longitudinal cutting pressure wheel 32, and another longitudinal cutting pressure wheel 32 can be installed in this installation hole. When the width of the redundant edge part 102 permits, the glass can be pressed and limited by two longitudinal cutting pressure wheels 32 simultaneously, further improving the cutting quality of the cutting seam.

[0055] Preferably, the cutting mechanism further includes a tappet 34. The tappet 34 is vertically disposed through the first part 331, and a cutting tool head 31 is connected to the end of the tappet 34. The tappet 34 is used to adjust the distance between the cutting tool head 31 and the first part 331. By adjusting the distance between the cutting tool head 31 and the first part 331, the distance between the cutting tool head 31 and the longitudinal cutting pressure wheel 32 in the vertical direction can be changed, thereby changing the depth of the cutting seam to meet the cutting requirements of glass with different thicknesses.

[0056] Preferably, the glass cutting device further includes a broken glass collection hopper 4. The broken glass collection hopper 4 is disposed below the conveying mechanism and is disposed at least 3 m away from the glass in the vertical direction. The height difference of 3 m can avoid the phenomenon that the broken glass formed after the excess edge 102 falls rebounds and damages the glass body 101. At the same time, since a plurality of edge-breaking wheels 21 are arranged at equal intervals along the horizontal first direction, the landing points of the excess edge 102 in the broken glass collection hopper 4 are also evenly dispersed along the horizontal first direction, avoiding the phenomenon that the inner wall of the collection hopper is easily penetrated due to concentrated landing points.

[0057] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
