[0047] In the overflow down-draw or slot down-draw process, the molten glass flows vertically downward after annealing to form a glass ribbon, which enters a transverse cutting device and is broken to form glass plates of specified sizes; during this process, the glass ribbon has a certain shape from top to bottom after flowing out of the annealing furnace, and it is required that this shape remains unchanged during the production process. However, in the actual production process, the thickness of the glass ribbon is small, and the pulling and forming speed is fast. The forming shape and quality of the glass are easily affected by the ambient air flow and the actions of the cutting and truncating devices. Especially when it is transversely cut and broken, the shape change of the glass ribbon is the most obvious, such as being bent or pulled awry, etc. After the shape changes, it seriously affects the product quality.

[0048] The glass forming guiding device provided in this embodiment is arranged between the annealing furnace and the transverse cutting device, and uses a first guiding mechanism and a second guiding mechanism that can approach or separate from each other to drive a first guiding wheel and a second guiding wheel to perform clamping guidance on the glass ribbon to be guided, so that the glass ribbon entering the entrance of the transverse cutting device is clamped and guided by the guiding wheels, keeping the state parameters of flowing out of the annealing furnace vertically, reducing or even avoiding the problem of deformation caused by the transverse cutting device, the pulling speed, the air flow, etc., and effectively improving the product quality.

[0049] Embodiment 1

[0050] Reference appendix Figure 1 and appendix Figure 2 , this embodiment discloses a glass forming guiding device arranged between an annealing furnace and a transverse cutting device, which includes a first guiding mechanism 1 and a second guiding mechanism 2 oppositely arranged along a first direction a, a first driving mechanism 3, a second driving mechanism 4 and a measuring scale 5; the first guiding mechanism 1 is movably arranged along the first direction a, and a first guiding wheel 11 is arranged on one side of the first guiding mechanism 1 facing the second guiding mechanism 2, and the first guiding wheel 11 can rotate around a second direction b, and both the first direction a and the second direction b are perpendicular to the vertical direction; the second guiding mechanism 2 is movably arranged along the first direction a, and a second guiding wheel 21 is arranged on one side of the second guiding mechanism 2 facing the first guiding mechanism 1, and the second guiding wheel 21 can rotate around the second direction b;

[0051] The first driving mechanism 3 is connected to the first guiding mechanism 1 and the second guiding mechanism 2 to drive the first guiding mechanism 1 and the second guiding mechanism 2 to approach or move away from each other along the straight line where the first direction a is located according to an electric driving signal; the second driving mechanism 4 is connected to the first driving mechanism 3, and the second driving mechanism 4 can rotate around the first direction a relative to the first driving mechanism 3 and drive the first driving mechanism 3 to reciprocate along the first direction a; the measuring scale 5 is arranged at least corresponding to the first guiding mechanism 1 or the second guiding mechanism 2 along the first direction a for measuring the moving distance of the first driving mechanism 3 in the first direction a.

[0052] It can be understood that, in order to solve the problem that the glass ribbon flowing out of the annealing furnace is easily deformed when entering the transverse cutting equipment for breaking, which affects the product quality, this embodiment provides a glass forming guiding device, which realizes the precise control of the first guiding mechanism 1 and the second guiding mechanism 2 through the electric drive and manual fine adjustment of the first driving mechanism 3 and the second driving mechanism 4, and clamps and guides the glass ribbon 7 to be guided, so as to avoid deformation when the glass ribbon 7 to be guided enters the transverse cutting equipment and is broken.

[0053] Among them, the first guiding mechanism 1 and the second guiding mechanism 2 are arranged oppositely along the first direction a. They can be directly opposite to each other in the first direction a, or can be offset and opposite to each other in the first direction a. Their movable setting along the first direction a can be achieved through the base 6. The base 6 is fixedly arranged and can be set on the ground, on a specified workbench surface, or at the entrance of a cross-cutting device. The first guiding mechanism 1 and the second guiding mechanism 2 can share the same base 6 or each be equipped with a base 6. Both the first guiding mechanism 1 and the second guiding mechanism 2 are slidably connected to the base 6 along the first direction a, so that they can reciprocate along the first direction a on the base 6. Correspondingly, the first guiding mechanism 1 and the second guiding mechanism 2 are of rigid structures, which can be, but are not limited to, frame structures, and can provide an installation position and a rotation space for the first guiding wheel 11 and the second guiding wheel 21. Both the first guiding wheel 11 and the second guiding wheel 21 are rigid wheel bodies, which can rotate around the first direction a. Then, when the glass ribbon 7 to be guided passes between the first guiding wheel 11 and the second guiding wheel 21, the first guiding wheel 11 and the second guiding wheel 21 can clamp the glass ribbon 7 to be guided and rotate towards each other as the glass ribbon 7 to be guided flows, so as to maintain the clamping and avoid affecting the shape of the glass ribbon 7 to be guided.

[0054] Among them, the first driving mechanism 3 is an electric driving mechanism, which can be, but is not limited to, a servo driving mechanism or a hydraulic driving mechanism. The first driving mechanism 3 can control the first guiding mechanism 1 and the second guiding mechanism 2 to approach or move away from each other in the first direction a, so as to adjust the clamping distance between the first guiding wheel 11 and the second guiding wheel 21 to adapt to glass ribbons of different specifications. It can be understood that the first driving mechanism 3 can be arranged on the base 6, and its driving end is connected to the first guiding mechanism 1 and the second guiding mechanism 2.

[0055] Among them, the second driving mechanism 4 is a structurally cooperative manual fine-tuning mechanism, which avoids the impact on the glass ribbon 7 to be guided caused by the control of pure electric drive. The second driving mechanism 4 can be but is not limited to a lead screw structure, a structure of a screw rod cooperating with a gear, as long as it can convert the rotational motion into a linear motion. In this embodiment, the second driving mechanism 4 is connected to the first driving mechanism 3. After the first driving mechanism 3 performs an automatic adjustment under an electric drive signal, if the first guide wheel 11 and / or the second guide wheel 21 are not attached to the glass ribbon 7 to be guided, fine-tuning can be performed through the second driving mechanism 4, so that the first driving mechanism 3 and the guiding mechanism move synchronously, and the clamping distance between the first guide wheel 11 and the second guide wheel 21 is adjusted again until both are attached to the glass ribbon 7 to be guided. The number of the first guide wheels 11 and the second guide wheels 21 can also be designed and adjusted according to actual needs. For example: two first guide wheels 11 and two second guide wheels 21 can be arranged in sequence in the second direction b. In this embodiment, the first guiding mechanism 1 and the second guiding mechanism 2 can be arranged corresponding to the two bait areas on both sides of the glass ribbon 7 to be guided. The bait area is a specified area at both ends in the width direction of the glass ribbon, and the bait area will be cut off during the subsequent cutting process. The area between the two bait areas is the quality area that needs to be reserved during the subsequent cutting process. This structure can be easily understood by those skilled in the art and will not be elaborated here. Furthermore, it can be understood that in this embodiment, the number of the first guide wheels 11 is at least two, and the two are arranged at intervals in the second direction b to respectively correspond to the two bait areas on the first side surface of the glass ribbon 7 to be guided. The number of the second guide wheels 21 is at least two, and the two are arranged at intervals in the second direction b to respectively correspond to the two bait areas on the second side surface of the glass ribbon 7 to be guided. When the guiding work is completed or the broken plate is restored, the first guiding mechanism 1 and the second guiding mechanism 2 can be controlled to move away from each other to improve the stability of the production line.

[0056] Among them, the measuring ruler 5 is a device or structure capable of measuring length, which can be but is not limited to a scale ruler. The measuring ruler 5 is fixedly arranged to be used as a reference and measurement reference for the movement of the first driving mechanism 3, and can be arranged on the base 6 or at the entrance of the cross-cutting device; the specification of the measuring ruler 5 can be designed and adjusted according to actual needs. For example: a millimeter scale ruler, which will not be elaborated here.

[0057] According to the above, it is arranged between the annealing furnace and the cross-cutting device. The first guiding mechanism 1 and the second guiding mechanism 2 that can approach or move away from each other are used to drive the first guide wheel 11 and the second guide wheel 21 to perform clamping guiding on the glass ribbon 7 to be guided, so that the glass ribbon entering the entrance of the cross-cutting device is clamped and guided by the guide wheels, and its state parameters of flowing out of the annealing furnace vertically are maintained, reducing or even avoiding the influence of the cross-cutting device or the traction speed, air flow, etc., effectively improving the product quality and enhancing the production controllability.

[0058] As used herein, the term "and / or" merely describes the associated relationship of associated objects and indicates three possible relationships. For example, A and / or B is specifically understood as follows: It can include both A and B simultaneously, A can exist alone, or B can exist alone, and any one of the above three situations can be satisfied.

[0060] It can be understood that, in order to simplify the installation of the glass forming guiding device, two bases 6 are provided in this embodiment to respectively support and install the first guiding mechanism 1 and the second guiding mechanism 2, so that the overall guiding device is installed in a split manner, reducing the installation difficulty of the overall guiding device; the base 6 is a rigid structure and can be in the form of a plate, a groove, a frame structure, etc. The base 6 and the cross-cutting device can be connected by welding, screwing, clamping, etc. and kept fixed. The measuring scale 5 is fixed on the base 6 and can be arranged by screwing, clamping, bonding, etc. The measuring scale 5 is arranged along the first direction a to provide a measurement reference for the movement of the first driving mechanism 3. The second driving mechanism 4 is arranged on the base 6 to drive the first driving mechanism 3. The first driving mechanism 3 is slidably connected to the base 6, and thus the second driving mechanism 4 can drive the first driving mechanism 3 and the guiding mechanism to reciprocate along the first direction a together.

[0061] In some embodiments, referring to the attached Figure 1 and the attached Figure 2 , for the glass forming guiding device provided in this embodiment, the first driving mechanism 3 includes a third driving part 31 and a fourth driving part 32; the third driving part 31 and the fourth driving part 32 are respectively arranged on the two bases 6, the driving end of the third driving part 31 is connected to the first guiding mechanism 1, and the driving end of the fourth driving part 32 is connected to the second guiding mechanism 2.

[0062] It can be understood that, in order to improve the control accuracy, in this embodiment, a third driving part 31 and a fourth driving part 32 are respectively provided corresponding to the first guiding mechanism 1 and the second guiding mechanism 2. The third driving part 31 and the fourth driving part 32 can be the same or different. For example: servo cylinders, hydraulic cylinders. The third driving part 31 and the fourth driving part 32 are respectively arranged on a base 6, and the driving ends of the two are adjacent and opposite, so as to be able to drive the first guiding mechanism 1 and the second guiding mechanism 2 to approach or separate from each other. In this embodiment, the electric driving signals of the third driving part 31 and the fourth driving part 32 can be generated and sent simultaneously, or can be generated separately and sent simultaneously, or can be generated asynchronously, as long as they can drive the first guiding mechanism 1 and the second guiding mechanism 2 to approach or separate from each other. And it can be understood that, in this embodiment, the number of the third driving part 31 and the fourth driving part 32 can both be 2, corresponding to two first guiding wheels 11 and two second guiding wheels 21 respectively; or the number of the third driving part 31 and the fourth driving part 32 can both be set to 1, then the two first guiding wheels 11 are simultaneously configured with the same third driving part 31, and the two second guiding wheels 21 are simultaneously configured with the same fourth driving part 32.

[0063] Further, referring to the attached Figure 1 , in some embodiments, for the glass forming guiding device provided in this embodiment, the first guiding mechanism 1 and the second guiding mechanism 2 further include a support frame 8; the support frame 8 at least includes a first connecting part 81 and a second connecting part 82; the first end of the first connecting part 81 is connected to the second driving mechanism 4, and the second end extends away from the base 6 in the vertical direction; the second connecting part 82 extends from the second end of the first connecting part 81 in a direction forming a specified angle with the first connecting part 81, and the end of the second connecting part 82 away from the first connecting part 81 is rotatably connected to the first guiding wheel 11 or the second guiding wheel 21.

[0064] It can be understood that, in order to ensure the guiding effect, in this embodiment, both guiding structures are set to include the support frame 8. The support frame 8 is a rigid frame structure, which may include a first connecting portion 81 and a second connecting portion 82. The first connecting portion 81 and the second connecting portion 82 may be, but are not limited to, plate-shaped, rod-shaped, frame-shaped structures, etc. In this embodiment, the first connecting portion 81 is used to extend a certain distance towards the annealing furnace relative to the base 6 to adjust the guiding position and ensure the guiding effect. The dimension of the first connecting portion 81 in the vertical direction can be designed and adjusted according to actual needs. Even the first connecting portion 81 can be set to a telescopic form to improve its application range; the second connecting portion 82 forms a specified angle with the first connecting portion 81, which may be perpendicular to the first connecting portion 81 or inclined upward or downward relative to the first connecting portion 81, as long as it can extend a certain distance in the first direction a to prevent the first driving mechanism 3 from interfering with the glass ribbon after being guided under the drive of the second driving mechanism 4. The dimension and inclination angle of the second connecting portion 82 can be designed and adjusted according to actual needs. The second connecting portion 82 and the first connecting portion 81 may be integrally formed or connected separately by welding, bonding or other forms. The end of the second connecting portion 82 away from the first connecting portion 81 can be rotatably connected to both ends of the guiding wheel to provide an installation position and rotational support for the guiding wheel.

[0065] Further, in some embodiments, for the glass forming guiding device provided in this embodiment, in specific implementation, both the third driving portion 31 and the fourth driving portion 32 are servo cylinders; the ejecting end of the servo cylinder is arranged along the first direction a and is connected to the first connecting portion 81 to eject or retract the first connecting portion 81 along the first direction a or the reverse direction of the first direction a according to the electric drive signal.

[0066] It can be understood that, in order to achieve efficient and convenient automatic electric drive, in this embodiment, both the third driving portion 31 and the fourth driving portion 32 are set to the form of servo cylinders. Furthermore, the mutual approach and separation of the first guiding mechanism 1 and the second guiding mechanism 2 only need to control the pulse directions of the two driving portions. Correspondingly, the driving ends of the third driving portion 31 and the fourth driving portion 32 are respectively connected to a first connecting portion 81, which may be, but are not limited to, welding, screwing, etc., to eject or retract the support frame 8 together with the corresponding guiding wheel.

[0067] In some embodiments, for the glass forming guiding device provided in this embodiment, in specific implementation, it further includes a controller (not shown in the figure); the controller is signal-connected to the third driving portion 31 and the fourth driving portion 32 to synchronously send electric drive signals to the third driving portion 31 and the fourth driving portion 32.

[0068] It can be understood that, in order to achieve efficient automatic control, a controller is provided in this embodiment. The controller is a PLC controller capable of data transceiver, analysis, comparison, and program editing. In this embodiment, the controller is simultaneously signal-connected to the third driving part 31 and the fourth driving part 32. Then, when clamping and guiding or canceling clamping and guiding are required, the controller is used to send an electric driving signal to the third driving part 31 and the fourth driving part 32 to achieve driving. By simultaneously driving the third driving part 31 and the fourth driving part 32 through the controller, the efficiency is greatly improved.

[0069] In some embodiments, for the glass forming guiding device provided in this embodiment, in a specific implementation, the second driving mechanism 4 includes a driving rod 9; the driving rod 9 is rotatably connected to the base 6 around the first direction a, and the end of the driving rod 9 is connected to the first driving mechanism 3; wherein, the driving rod 9 rotates around the first direction a to drive the first driving mechanism 3 to reciprocate along the first direction a relative to the base 6.

[0070] It can be understood that, to realize the fine-tuning function of the second driving mechanism 4, in this embodiment, the second driving mechanism 4 is set to include a driving rod 9. The driving rod 9 can be, but is not limited to, a screw rod. It is rotatably connected to the base 6 and can be, but is not limited to, penetrating into the base 6 to abut against the first driving mechanism 3. During the rotation of the driving rod 9, a linear motion is generated, causing the first driving mechanism 3 to perform a linear motion. Then, when the automatic driving of the first driving mechanism 3 cannot satisfy the condition that the two guiding wheels simultaneously contact the glass belt 7 to be guided, manual fine-tuning can be performed through the driving rod 9. For example, check the distance between the guiding wheel and the glass belt 7 to be guided, and use a measuring ruler 5 and the distance data to control the start and stop of the manual fine-tuning, improve the control accuracy, and slowly compress the shaking amplitude of the glass belt 7 to be guided to make it in a state of natural vertical descent, achieving the purpose of stable guiding.

[0072] It can be understood that, in order to improve the stable guiding of the guiding device for the glass ribbon 7 to be guided and avoid scratching the glass ribbon and affecting its related parameters, in this embodiment, a buffer layer is provided on the first guiding wheel 11 and the second guiding wheel 21. The buffer layer has elasticity and can be, but is not limited to, a rubber layer, a clean rubber ring, etc., to ensure non-rigid contact or extrusion when contacting the glass ribbon 7 to be guided. The buffer layer can cover the entire axial outer surface of the guiding wheel, or can be provided only for the middle position that can contact the glass ribbon 7 to be guided. The setting methods or positions of the buffer layers on the first guiding wheel 11 and the second guiding wheel 21 can be the same or different. For example: The buffer layer covers the axial outer surfaces of the first guiding wheel 11 and the second guiding wheel 21, effectively ensuring that the contact positions with the glass ribbon 7 to be guided are all covered by the buffer layer to be applicable to glass ribbons of different specifications. Another example: The buffer layer includes a plurality of sub-buffer layers, and the plurality of sub-buffer layers are arranged at intervals along the axial direction of the first guiding wheel 11 or the second guiding wheel 21. The buffer layer is arranged around the axial direction of the first guiding wheel 11 or the second guiding wheel 21 for one week, that is, in a discontinuous manner. The plurality of sub-buffer layers form a surface protruding from the axial outer surface of the guiding wheel itself in the axial direction of the first guiding wheel 11 and the second guiding wheel 21 for contacting the glass ribbon 7 to be guided, which can not only play a buffering role but also effectively reduce the overall weight of the guiding wheel, and can also reduce the disassembly difficulty of the sub-buffer belt, providing convenience for subsequent maintenance and replacement.
