Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic glass processing, in particular to low-reflection photovoltaic glass rolling and molding equipment. Background Art

[0002] Low-reflection photovoltaic glass is a type of glass that has been treated with a special coating or physical embossing on its surface. It can effectively reduce the reflection of sunlight on the glass surface, allowing more sunlight to penetrate the glass and reach the photovoltaic modules, thereby improving the photoelectric conversion efficiency. During the processing of photovoltaic glass, the molten glass liquid needs to be rolled into glass of the required thickness through rollers.

[0003] A patent with the announcement number CN218465682U discloses a calendering roller for photovoltaic glass calendering equipment, which belongs to the field of glass processing technology and includes a fixed plate, on which two symmetrically arranged calendering roller bodies are provided. The two calendering roller bodies are connected to the same operating frame, and two symmetrically arranged receiving frames are slidably connected in the operating frame. The utility model uses a rotating shaft, a driven shaft and a blowing fan blade in combination. When the calendering roller body rotates, the blowing fan blade is rotated under the action of the driving gear and the driven gear, thereby generating a certain amount of wind force and blowing toward the calendering roller body, accelerating the heat dissipation of the calendering roller body surface and preventing the glass from sticking to the calendering roller body. In addition, by providing a movable plate and a movable shaft, the movable shaft can be rotated to make the two calendering roller bodies move relative to or opposite to each other, so that photovoltaic glass of different thicknesses can be processed, thereby improving the practicality of the device.

[0004] However, since the calendering roller used in existing photovoltaic glass equipment can only move and adjust the distance at one end when in use, and the other end is fixed to a fixed plate and cannot be adjusted, it is impossible to calender glass of different thicknesses. In addition, during use, since the calendering roller is in direct contact with the high-temperature glass solution, the existing calendering roller can only be cooled by air at one end, and the cooling effect is poor. Moreover, cooling only one end of the calendering roller can easily cause inconsistent temperature of the calendering roller and deformation, thereby affecting the calendering effect of the photovoltaic glass. Therefore, a low-reflection photovoltaic glass calendering molding equipment is proposed to address the above problems. Utility Model Content

[0045] The calendering assembly 4 includes a hollow roller 41, an inner roller 42 is arranged inside the hollow roller 41, and evenly distributed support ribs 43 are arranged between the curved surface of the inner roller 42 and the inner wall of the hollow roller 41. Both ends of the hollow roller 41 are fixedly connected to a hollow shaft 44 connected to its interior, and the water outlet pipe 5 and the water inlet pipe 6 are respectively rotatably connected to the two ends of the hollow shaft 44 on both sides of the hollow roller 41.

[0046] The lifting assembly 7 includes a U-shaped frame 71, and a plurality of hydraulic rods 72 are arranged horizontally and fixed in the U-shaped opening of the U-shaped frame 71, and the hydraulic rods 72 are fixed to the upper part of the rolling chamber 2. The two ends of the opening of the lifting assembly 7 are respectively rotatably connected to the two hollow shafts 44 at the two ends of the hollow roller 41.

[0047] The No. 1 drive assembly 12 includes a No. 1 motor 121, which is slidably mounted on the base 16. A universal joint coupling 122 is mounted on the output shaft of the No. 1 motor 121. The end of the universal joint coupling 122 is fixedly connected to a No. 1 gear 123. A No. 1 gear ring 124 meshing with the No. 1 gear 123 is provided under the No. 1 gear 123, and the No. 1 gear ring 124 is fixedly connected to the hollow shaft 44 at one end of the upper hollow roller 41, and the No. 1 gear 123 is rotatably mounted on the outside of the U-shaped frame 71.

[0048] The No. 2 drive assembly 13 includes a No. 2 motor 131, which is mounted on the base plate 1 via a fixing member. A No. 2 gear 132 is fixedly connected to the output shaft of the No. 2 motor 131. A No. 3 gear ring 133 is provided on the No. 2 gear 132 and is meshed with the No. 3 gear ring 133. The No. 3 gear ring 133 is mounted on the hollow shaft 44 at one end of the lower hollow roller 41.

[0049] A plurality of conveying rollers 14 are arranged transversely and rotatably connected in the calendering bin 2 , a third motor 15 for driving the plurality of conveying rollers 14 to rotate is installed on the bottom plate 1 through a fixing member, and the plurality of conveying rollers 14 are connected by a chain transmission.

[0050] During operation, the calendering roller of the existing photovoltaic glass equipment can only be moved and adjusted at one end, while the other end is fixed to the fixed plate, and the distance cannot be adjusted, and thus it is impossible to calender glass of different thicknesses. Moreover, during use, since the calendering roller is in direct contact with the high-temperature glass solution, the existing calendering roller can only be cooled by air at one end, and the cooling effect is poor. Moreover, cooling only one end of the calendering roller is likely to cause inconsistent temperature of the calendering roller and deformation, thereby affecting the calendering effect of the photovoltaic glass. In this solution, by controlling the No. 1 motor 121 and When the No. 2 motor 131 is running, the No. 1 motor 121 rotates, driving the No. 1 gear 123 to rotate via the universal joint coupling 122. When the No. 1 gear 123 rotates, it drives the upper calendering assembly 4 to rotate via the No. 1 gear ring 124, and causes the upper calendering assembly 4 to rotate in the guide grooves 3 provided on both sides of the calendering chamber 2. When the No. 2 motor 131 is running, it drives the No. 2 gear 132 to rotate, and drives the lower calendering assembly 4 to rotate in the calendering chamber 2 via the No. 3 gear ring 133, thereby driving the two groups of calendering assemblies 4 to rotate in the calendering chamber 2.

[0051] The molten glass liquid is poured into the feeding port of the rolling chamber 2 and guided by the upper structure of the rolling chamber 2 into the space between the two rolling assemblies 4. Under the synchronous rolling of the two rolling assemblies 4, the glass liquid entering between the two rolling assemblies 4 is rolled and formed. The No. 3 motor 15 drives the multiple conveying rollers 14 in the rolling chamber 2. The rolled and formed glass is then conveyed to the discharge port of the rolling chamber 2 for discharge.

[0052] When the two groups of rolling assemblies 4 are in operation, the delivery pump 9 is controlled to operate. When the delivery pump 9 is in operation, the coolant in the liquid storage tank 8 is pumped into the two groups of rolling assemblies 4 through the liquid delivery pipe 11, and the coolant is pumped into the hollow roller 41 through the water inlet pipe 6 and the hollow shaft 44 connected to the water inlet pipe 6. By pumping the coolant into the hollow roller 41, the glass solution is cooled by the coolant in the hollow roller 41 when entering the two groups of rolling assemblies 4, and the glass solution entering between the two groups of rolling assemblies 4 is cooled, thereby improving the rolling forming effect of the glass. Under the continuous operation of the delivery pump 9, the coolant in the hollow roller 41 enters the water outlet pipe 5 from the hollow shaft 44 at the other end thereof, and circulates into the liquid storage tank 8 through the return pipe 10, thereby ensuring its cooling and forming effect.

[0053] When it is necessary to adjust the distance between the two groups of rolling assemblies 4, the multiple hydraulic rods 72 are controlled to extend and retract, thereby adjusting the height of the U-shaped frame 71. After the height of the U-shaped frame 71 changes, it will drive the upper rolling assembly 4 to rise and fall in the guide groove 3 on the side of the rolling chamber 2, thereby adjusting the distance between the two groups of rolling assemblies 4, so as to be suitable for rolling and forming glasses of different thicknesses. When the height of the U-shaped frame 71 is adjusted, the No. 1 gear 123 will be driven to rise and fall, and at the same time, the end of the universal joint coupling 122 opposite to the No. 1 motor 121 will be driven to rise and fall. When the angle of the universal joint coupling 122 changes, it will drive the No. 1 motor 121 to slide on the support platform 16, so as to ensure the driving effect of the No. 1 motor 121 on the upper rolling assembly 4.

[0054] The combination achieves the ability to calender and form glass of different sizes. Compared with traditional glass calendering equipment, it has a better effect on glass molding and the cooling effect of the equipment itself, effectively avoiding deformation caused by inconsistent temperature of the calendering rollers and ensuring the glass molding effect.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
