For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Please refer to Figure 1 and Figure 2 The preferred embodiment of the present invention provides a glass edge-bending pre-cooling device, comprising a bracket 10, a mounting frame 20, a water inlet pipe 30, a water guide member 40, and a cooling unit 41. The device is used to cool the edge of the float glass during the edge-bending operation. The cooled glass achieves a smoother fracture surface and better edge quality.

[0032] The bracket 10 serves as a support component for the entire device. Mounting brackets 20 are located on either side of the bracket 10. The mounting brackets 20 on either side of the bracket 10 are positioned above the edges of the glass to be bent, respectively, so that they can simultaneously act on both sides of the glass during bending.

[0033] The water inlet pipes 30 are mounted on the mounting brackets 20 on either side. Multiple water outlet holes are defined in the wall of the water inlet pipes 30 for discharging water. In this exemplary embodiment, one end of the water inlet pipes 30 is sealed, while the other end is connected to an external water source, such as municipal tap water. Water flows out of the water outlet holes in the wall of the water inlet pipes 30.

[0034] The upper part of the water guide member 40 is sleeved on the water inlet pipe 30 and covers the water outlet of the water inlet pipe 30 to receive the cooling water from the water outlet of the water inlet pipe 30 and guide the cooling water to the lower part of the water guide member 40, that is, the water from the water outlet of the water inlet pipe 30 can be guided downward through the water guide member 40. The water guide member 40 is sleeved on the water outlet of the water inlet pipe 30, so the cooling water will not spray out, but enter the water guide member 40 and flow downward along the water guide member 40. The cooling part 41 is provided at the lower part of the water guide member 40. The cooling part 41 is used to abut against the two side edges of the glass to be bent to guide the cooling water to the two side edges of the glass to be bent. The water guided downward by the water guide member 40 flows to the cooling part 41, and the wet cooling part 41 applies the cooling water to the two side edges of the glass to be bent (at the scratch position), thereby achieving cooling of this position. The cooling part 41 can be integrated with the water guide member 40.

[0035] After the float glass is formed and annealed, it still has a certain temperature (generally more than 100 degrees Celsius). Although there will be scratches at the edge breaking position before breaking, due to the high temperature and good plasticity of the glass, the flatness of the broken edge is not high and the edge breaking quality is not high. If the glass is naturally cooled and the temperature is lowered during breaking, it is necessary to wait for a certain time before breaking, which seriously affects the production efficiency. Based on this, the utility model proposes a pre-cooling device for glass edge breaking, which is installed on the conveying path of the float glass and is cooled before breaking, which belongs to pre-cooling. When implementing, you can refer to Figure 3The float glass 60 to be bent is conveyed by the conveying mechanism toward the bend device and passes through the pre-cooling device for glass bend of the present invention. In the present invention, the water guide member 40 naturally droops. At this time, the cooling portion 41 is in contact with the portion of the float glass to be bent. Cooling water is fed into the water inlet pipe 30 through an external water source. The cooling water flows out from the water outlet hole on the wall of the water inlet pipe 30, enters the water guide member 40, and is guided downward along the water guide member 40 and reaches the cooling portion 41. Since the cooling portion 41 is in contact with the portion of the float glass to be bent, the cooling water flows along the cooling portion 41 to the portion of the float glass to be bent and cools the portion of the glass to be bent. After the cooled glass is bent, the fracture surface of the glass is smoother and the edge breaking quality is better.

[0036] In a preferred embodiment, the bracket 10 is provided with a transverse slide rail 11, and the mounting frame 20 is slidably mounted on the slide rail 11, so that the mounting frames 20 on both sides can move closer to or farther away from each other when sliding on the transverse slide rail 11. Considering that the distance between the two edge-breaking positions varies depending on the specifications of the glass, it is necessary to adjust the position of the mounting frame 20 to adjust the position of the water guide member 40 and the cooling unit 41. By adjusting the position of the mounting frame 20 by sliding it on the slide rail 11, the positions of the two mounting frames 20 and the water guide member 40 and the cooling unit 41 thereon can be adjusted to accommodate the cooling of the edge-breaking positions of glass of different widths.

[0037] In a preferred embodiment, a screw rod 12 is rotatably mounted within the slide rail 11 of the bracket 10. The threads at both ends of the screw rod 12 rotate in opposite directions. Sliders 13 are threadedly connected to each end of the screw rod 12. Sliders 13 slide on the slide rail 11. The screw rod 12, sliders 13, and slide rail 11 together form a screw assembly. Rotating the screw rod 12 drives the sliders 13 along the slide rail 11. Because the threads at both ends of the screw rod 12 rotate in opposite directions, the two slides 13 move toward or away from each other on the slide rail 11 when the screw rod 12 rotates. The mounting frame 20 is installed on the slider 13. When the two sliders 13 move closer to or away from each other on the slide rail 11, the two mounting frames 20 also move closer to or away from each other, and the water guide parts 40 and the cooling part 41 thereon move closer to or away from each other accordingly. When the two water guide parts 40 are close to each other, the distance is relatively close, which is suitable for cooling the edges of glass with a narrower width. When the two water guide parts 40 are away from each other, the distance is relatively far, which is suitable for cooling the edges of glass with a wider width. Through adjustment, the water guide parts 40 can adapt to the edge bending work of float glass of different widths.

[0038] Further, one end of the screw rod 12 is provided with a hand wheel 14, and the screw rod 12 can be rotated by shaking the hand wheel 14 to adjust the distance between the two water guide members 40. In order to facilitate manual shaking, the two ends and the middle part of the screw rod 12 are installed in the slide rail 11 through bearings 16.

[0039] The portion of the slider 13 extending from the rail 11 is provided with a downwardly extending through-hole. The side of the slider 13 is provided with a threaded hole extending into the through-hole, and a locking bolt 15 is disposed within the threaded hole. The mounting frame 20 is provided with a vertical rod 21 that matches the through-hole. The vertical rod 21 is inserted into the through-hole and can be tightened to the slider 13 by tightening the locking bolt 15. The locking bolt 15 is a butterfly bolt for easy hand tightening. By adjusting the position of the vertical rod 21 of the mounting frame 20 within the through-hole, the height of the mounting frame 20 can be adjusted, thereby adjusting the height of the water guide 40 and the cooling unit 41. This, in turn, adjusts the contact area of ​​the cooling unit 41 with the float glass to adjust the amount of cooling water directed to the glass. This allows for adaptability to conveyor mechanisms of varying heights and adjusts the degree of cooling. It is understandable that the degree of cooling can be adjusted by adjusting the amount of cooling water guided to the glass by the cooling portion 41. On the one hand, the above-mentioned method can be adopted, and other methods can also be adopted, such as adjusting the width of the cooling portion 41 and adjusting the amount of cooling water entering the glass, such as setting a valve on the water inlet pipe 30 or the water inlet pipeline, and adjusting the opening of the valve to adjust the amount of water entering the glass.

[0040] Preferably, the through hole is a square through hole, which can ensure that the mounting frame 20 does not rotate compared to the slider 13, making the mounting frame 20 more stable. In this exemplary embodiment, the mounting frame 20 is Y-shaped as a whole, with the vertical rod 21 facing upward and matching the through hole of the slider 13. The two lower legs are respectively connected to the water inlet pipe 30, which is arranged horizontally.

[0041] The water guide 40 is a cloth strip, sponge, cotton, or a bag-like structure. The bag-like structure is preferably a cloth bag, with its upper portion fitted over the outlet of the water inlet pipe 30 to draw cooling water into it. The cooling portion 41 is a horizontal arrangement of cloth strips, sponges, or cotton connected to the cloth strip, sponge, or cotton bag-like structure of the water guide 40. In an exemplary embodiment, the water guide 40 is a bag-like structure made of cloth, or a solid cloth strip, with its upper portion fitted over the outlet of the water inlet pipe 30 to draw cooling water into the bag or cloth strip. The cooling portion 41 is a horizontal arrangement of cloth strips connected to the interior of the water guide 40, which is a bag-like structure or cloth strip structure. The cooling portion 41 is integrally formed with the water guide 40. During operation, cooling water enters the outlet of the water inlet pipe 30. The cloth strip or cloth bag stores and draws the water downward, directing it to the cooling portion 41 of the cloth strip and then to the glass, where it contacts the cooling water as it passes through, achieving cooling. It is understandable that the cloth strips are not limited to strip-shaped structures, and may also be columnar, block-shaped or other structures with a certain thickness.

[0042] In a preferred embodiment, the glass edge-breaking pre-cooling device further includes an air nozzle 50, which is located on both sides of the bracket 10 and at the rear of the cooling unit 41. That is, the air nozzle 50 is located at the rear of the cooling unit 41 on the conveying path, and is first cooled by the cooling unit 41 and then blown through the air nozzle 50. The air nozzle 50 is connected to an external compressed air source and is arranged outward. The external compressed air source blows air through the air nozzle 50 toward the edge-breaking position of the float glass after cooling with cooling water. The air is blown outward, so that the cooling water on the glass can be blown away from the glass. On the one hand, the water can be blown away to keep the glass clean and dry, and on the other hand, further cooling can be achieved by blowing air.

[0043] In a preferred embodiment, the air nozzle 50 is connected to an external compressed air source through a universal bamboo tube 51. The position of the air nozzle 50 can be adjusted through the universal bamboo tube 51, thereby adjusting the blowing position to adapt to the use of float glass of different widths.

[0044] The glass edge breaking pre-cooling device of the utility model guides cooling water to the position of the float glass to be broken by arranging a water guide member and a cooling part, thereby cooling the portion of the float glass to be broken, thereby improving the flatness of the broken edge of the float glass and ensuring the quality of the broken edge.

[0045] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
