[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, first start the built-in heaters of one side of the mold and the heat-conducting steel sheet, transfer the heated and softened glass onto the preheated mold and heat-conducting steel sheet on one side by the robotic arm, then start Motor 1 to drive Screw 1 to rotate, Screw 1 drives Hydraulic Cylinder 1 to slide left and right, Hydraulic Cylinder 1 drives the lifting frame and the flexible heat-resistant belt to move as a whole, then start Hydraulic Cylinder 1 to drive the lifting frame and the flexible heat-resistant belt to descend, and stop when the left side of the flexible heat-resistant belt is located on the right side of the mold and the heat-conducting steel sheet. Start Motor 2 to drive Screw 2 to rotate, Screw 2 drives the push plate to slide leftward, pushing the flexible heat-resistant belt to slide leftward on the lifting frame. The flexible heat-resistant belt gradually disengages from the lifting frame and is manually guided to cover the softened glass on the mold and the heat-conducting steel sheet. Start Hydraulic Cylinder 2 to push the telescopic rod and the pressure roller to reciprocate left and right. The set pressure roller facilitates the reciprocating rolling of the upper end of the flexible heat-resistant belt. The set telescopic rod and Spring 3 facilitate the adaptive telescopic adjustment according to the bending angle of the mold. After the pressure roller reciprocates and presses multiple times, the softened glass located between the flexible heat-resistant belt, the mold and the upper end of the heat-conducting steel sheet can be bent and shaped. The set built-in heater facilitates the preheating of one side of the mold and the heat-conducting steel sheet, effectively preventing the softened glass that has not been pressed and shaped by the pressure roller on one side of the mold and the heat-conducting steel sheet from cooling and hardening, thereby improving the bending and processing quality of the softened glass. When the softened glass on one side of the mold and the heat-conducting steel sheet is bent and shaped, then start the cooling device to circulate and pump the coolant through its built-in circulating pump and circulating pipe, which facilitates the rapid cooling of the bent and shaped mold and heat-conducting steel sheet on one side, accelerating the forming efficiency of the softened glass. After the softened glass on one side of the mold and the heat-conducting steel sheet is pressed, bent and shaped, the staff can simultaneously place the softened glass to be bent on the other side of the mold and the heat-conducting steel sheet. At the same time, drive the flexible heat-resistant belt to move to the upper side of the other side of the mold and the heat-conducting steel sheet and reset it through Motor 1, Hydraulic Cylinder 1 and Motor 2, and repeat the above operation process to press, bend and shape the softened glass on the other side. By operating alternately in this way, the efficiency of glass bending and processing can be greatly improved, thereby improving the work efficiency.

[0017] 2. In the present invention, the bending angles of the molds on both sides are different, which facilitates the simultaneous processing of two glass products with different bending degrees according to actual needs, and has a wide adaptability.

[0018] 3. In the present invention, when the screw rod three rotates to drive the movable plate and the disassembly plate to slide downwards, the upper end of the disassembly plate will gradually descend from the middle of the mold, so that the middle part of the lower end of the glass product after bending and cooling forming will be separated from the disassembly plate. As the screw rod three continues to rotate, the movable plate will continue to descend, and at the same time, it will also drive the rack two to descend. The rack two will engage with the gear shaft, driving the gear shaft to rotate. The gear shaft drives the rack one and the ejector rod to rise, so that the upper end of the ejector rod is ejected from the mold, facilitating the ejection and detachment of the glass product after bending and cooling forming, improving the disassembly efficiency of the glass product after bending and cooling forming, being conducive to the staff to place the softened glass to be bent on the mold again, and accelerating the efficiency of glass bending and processing forming.

[0019] 4. In the present invention, the disassembly plate first separates from the glass product after bending forming, and then the glass product is completely ejected and disassembled by the ejector rod. Compared with the existing method of directly removing the entire glass product from the mold, it will reduce the situations of cracking or breakage and difficult disassembly when the glass product is disassembled, improving the quality and efficiency of glass bending processing.

[0020] 5. In the present invention, when the push plate pushes the flexible heat-resistant belt to slide leftward on the lifting frame, the upper surface of the flexible heat-resistant belt will be continuously scraped by the cleaning strip. The cleaning strip is under the pressure of the spring one and will closely adhere to the upper surface of the flexible heat-resistant belt. The arranged cleaning strip is convenient for uniformly cleaning the glass debris or impurities remaining on the upper end of the flexible heat-resistant belt, avoiding the situation that when the upper end of the flexible heat-resistant belt is squeezed by the pressure roller later, the upper surface is uneven due to the glass debris or impurities remaining on the upper end of the flexible heat-resistant belt, thus affecting the uniform force application of the pressure roller on the upper end of the flexible heat-resistant belt and then affecting the quality of glass processing and forming, ensuring the quality of glass bending and forming processing.

[0021] 6. In the present invention, when the push plate gradually pushes the flexible heat-resistant belt to slide leftward on the lifting frame, the top plate will gradually approach and squeeze the pressing plate. The pressing plate slides on the support plate, compressing the airbag and the spring two, so that the gas in the airbag is ejected through the connecting pipe and the nozzle groove. The ejected gas is convenient for blowing off the glass debris and impurities scraped and concentrated on the right side of the upper end of the flexible heat-resistant belt by the cleaning strip, reducing the situation of more glass debris and impurities remaining on the flexible heat-resistant belt.

[0022] 7. In the present invention, when the pressure roller uniformly presses and rolls on the upper end of the flexible heat-resistant belt, under the action of friction, it will rotate on the connecting plate. The arranged protection plates on both sides are attached to the two side surfaces of the pressure roller under the action of the spring four. The arranged protection plates are convenient for preventing glass debris from splashing and falling near the pressure roller during the pressing work, causing the surface of the flexible heat-resistant belt to be uneven, and can also scrape off the softened glass fragments splashed and adhered to the surface of the pressure roller, avoiding the situation that the surface of the pressure roller is uneven after long-term work, thus improving the quality of glass bending processing.

Transfer the heated and softened glass onto the preheated mold 8 and heat-conducting steel sheet 9 on one side by means of a robotic arm. Then start the first motor 4 to drive the first screw 3 to rotate. The first screw 3 drives the first hydraulic cylinder 5 to slide left and right. The first hydraulic cylinder 5 drives the lifting frame 6 and the flexible heat-resistant belt 7 to move as a whole. Then start the first hydraulic cylinder 5 to drive the lifting frame 6 and the flexible heat-resistant belt 7 to descend. Stop when the left side of the flexible heat-resistant belt 7 is located on the right side of the mold 8 and the heat-conducting steel sheet 9. Start the second motor 13 to drive the second screw 12 to rotate. The second screw 12 drives the push plate 11 to slide leftward, pushing the flexible heat-resistant belt 7 to slide leftward on the lifting frame 6. The flexible heat-resistant belt 7 gradually disengages from the lifting frame 6 and is manually guided to cover the softened glass on the mold 8 and the heat-conducting steel sheet 9. Start the second hydraulic cylinder 26 to push the telescopic rod 25 and the pressure roller 23 to reciprocate left and right. The arranged pressure roller 23 facilitates the reciprocating rolling of the upper end of the flexible heat-resistant belt 7. The arranged telescopic rod 25 and the third spring 27 facilitate the adaptive telescopic adjustment according to the bending angle of the mold 8. After the pressure roller 23 reciprocates and presses multiple times, the softened glass located between the upper ends of the flexible heat-resistant belt 7, the mold 8, and the heat-conducting steel sheet 9 can be bent and shaped. The arranged built-in heaters facilitate the preheating of the mold 8 and the heat-conducting steel sheet 9 on one side, effectively preventing the softened glass that has not been pressed and formed by the pressure roller 23 on the mold 8 and the heat-conducting steel sheet 9 on one side from cooling and hardening, thereby improving the bending and processing quality of the softened glass. When the softened glass on the mold 8 and the heat-conducting steel sheet 9 on one side is bent and formed, start the cooling device 31 to circulate and pump the coolant through its built-in circulating pump and circulating pipe 32, facilitating the rapid cooling of the bent and formed mold 8 and heat-conducting steel sheet 9 on one side, and accelerating the forming efficiency of the softened glass. After the softened glass on the mold 8 and the heat-conducting steel sheet 9 on one side is pressed, bent, and formed, the staff can simultaneously place the softened glass to be bent on the mold 8 and the heat-conducting steel sheet 9 on the other side. At the same time, drive the flexible heat-resistant belt 7 to move above the mold 8 and the heat-conducting steel sheet 9 on the other side and reset the flexible heat-resistant belt 7 through the first motor 4, the first hydraulic cylinder 5, and the second motor 13. Repeat the above operation process to press, bend, and form the softened glass on the other side. By operating alternately in this way, the bending and processing efficiency of the glass can be greatly improved, thereby improving the work efficiency. Moreover, the bending angles of the molds 8 on both sides are different, facilitating the simultaneous processing of two glass products with different bending degrees according to actual needs, and having a wide adaptability. When the push plate 11 pushes the flexible heat-resistant belt 7 to slide leftward on the lifting frame 6, the upper surface of the flexible heat-resistant belt 7 will be continuously scraped by the cleaning strip 14. The cleaning strip 14 is under the pressure of the first spring 16 and will closely adhere to the upper surface of the flexible heat-resistant belt 7. The arranged cleaning strip 14 facilitates the uniform cleaning of the glass debris or impurities remaining on the upper end of the flexible heat-resistant belt 7, avoiding the situation where the upper surface is uneven due to the glass debris or impurities remaining on the upper end of the flexible heat-resistant belt 7 when the upper end of the flexible heat-resistant belt 7 is squeezed by the pressure roller 23 later.This affects the uniform force of the pressure roller 23 and applies pressure to the upper end of the flexible heat-resistant belt 7, thereby affecting the quality of glass processing and molding, ensuring the quality of glass bending and molding. At the same time, when the push plate 11 pushes the flexible heat-resistant belt 7 to gradually slide to the left on the lifting frame 6, the top plate 22 will gradually approach and squeeze the pressure plate 21. The pressure plate 21 slides on the support plate 141, compressing the airbag 19 and the spring 20, so that the gas in the airbag 19 is ejected through the connecting pipe 18 and the nozzle groove 17. The ejected gas makes it easy to scrape the glass debris and impurities concentrated on the right side of the upper end of the flexible heat-resistant belt 7 by the cleaning strip 14 and blow them off, reducing the flexible heat-resistant belt 7. In the case where there are a lot of glass fragments and impurities left on the belt 7, when the pressure roller 23 uniformly presses and rolls the upper end of the flexible heat-resistant belt 7, it will rotate on the connecting plate 24 under the action of friction, and the protective plates 28 on both sides are attached to the surfaces of the two sides of the pressure roller 23 under the action of the spring 430.

The upper end of the demolding plate 33 gradually descends from the middle of the mold 8, causing the middle part of the lower end of the glass product after bending and cooling to separate from the demolding plate 33. As the third screw 39 continues to rotate, the movable plate 38 will continue to descend, and at the same time, it will also drive the second rack 37 to descend. The second rack 37 will engage with the gear shaft 36, driving the gear shaft 36 to rotate. The gear shaft 36 drives the first rack 35 and the ejector rod 34 to rise, so that the upper end of the ejector rod 34 is ejected from the mold 8, facilitating the ejection and separation of the glass product after bending and cooling, improving the disassembly efficiency of the glass product after bending and cooling, being conducive to the staff placing the softened glass to be bent on the mold 8 again, accelerating the efficiency of glass bending and processing, and the demolding plate 33 first separates from the glass product after bending and forming, and then the glass product is completely ejected and disassembled by the ejector rod 34. Compared with the existing method of directly removing the entire glass product from the mold 8, it will reduce the situation of cracking or damage and difficult disassembly when the glass product is disassembled, improving the quality and efficiency of glass bending processing.

[0028] Working principle: When the present invention is in use, first start the built-in heaters of the mold 8 and the heat-conducting steel sheet 9 on one side, transfer the heated and softened glass onto the preheated mold 8 and heat-conducting steel sheet 9 on one side by means of a robotic arm, then start the first motor 4 to drive the first screw 3 to rotate. The first screw 3 drives the first hydraulic cylinder 5 to slide left and right. The first hydraulic cylinder 5 drives the lifting frame 6 and the flexible heat-resistant belt 7 to move as a whole. Then start the first hydraulic cylinder 5 to drive the lifting frame 6 and the flexible heat-resistant belt 7 to descend. After the left side of the flexible heat-resistant belt 7 is located at the right side of the mold 8 and the heat-conducting steel sheet 9, stop. Start the second motor 13 to drive the second screw 12 to rotate. The second screw 12 drives the push plate 11 to slide leftward, pushing the flexible heat-resistant belt 7 to slide leftward on the lifting frame 6. The flexible heat-resistant belt 7 gradually disengages from the lifting frame 6 and is manually guided to cover the softened glass on the mold 8 and the heat-conducting steel sheet 9. Start the second hydraulic cylinder 26 to push the telescopic rod 25 and the pressure roller 23 to reciprocate left and right. The provided pressure roller 23 is convenient for reciprocally rolling the upper end of the flexible heat-resistant belt 7. The provided telescopic rod 25 and the third spring 27 are convenient for adaptive telescopic adjustment according to the bending angle of the mold 8. After the pressure roller 23 reciprocally presses multiple times, the softened glass located between the upper ends of the flexible heat-resistant belt 7, the mold 8 and the heat-conducting steel sheet 9 can be bent and shaped. The provided built-in heaters are convenient for preheating the mold 8 and the heat-conducting steel sheet 9 on one side, effectively preventing the softened glass that has not been pressed and formed by the pressure roller 23 on the mold 8 and the heat-conducting steel sheet 9 on one side from cooling and hardening, thereby improving the bending processing and forming quality of the softened glass. When the softened glass on the mold 8 and the heat-conducting steel sheet 9 on one side is bent and formed, then start the cooling device 31 to circulate and pump the coolant through the built-in circulating pump and the circulating pipe 32, which is convenient for quickly cooling the bent and formed mold 8 and heat-conducting steel sheet 9 on one side, accelerating the forming efficiency of the softened glass. After the softened glass on the mold 8 and the heat-conducting steel sheet 9 on one side is pressed, bent and formed, the staff can simultaneously place the softened glass to be bent on the mold 8 and the heat-conducting steel sheet 9 on the other side. At the same time, drive the flexible heat-resistant belt 7 to move to the upper side of the mold 8 and the heat-conducting steel sheet 9 on the other side and reset the flexible heat-resistant belt 7 through the first motor 4, the first hydraulic cylinder 5 and the second motor 13. Repeat the above operation process to press, bend and form the softened glass on the other side. By operating alternately in this way, the bending processing and forming efficiency of the glass can be greatly improved, thereby improving the work efficiency. Moreover, the bending angles of the molds 8 on both sides are different, which is convenient for simultaneously processing two glass products with different bending degrees according to actual needs, and has a wide adaptability. Rotate the third screw 39 to drive the movable plate 38 and the disassembling plate 33 to slide downward. The upper end of the disassembling plate 33 will gradually descend from the middle of the mold 8, so that the middle part of the lower end of the bent, cooled and formed glass product will be separated from the disassembling plate 33. As the third screw 39 continues to rotate, the movable plate 38 will continue to descend, and at the same time will also drive the second rack 37 to descend. The second rack 37 will engage with the gear shaft 36, driving the gear shaft 36 to rotate. The gear shaft 36 drives the first rack 35 and the ejector rod 34 to rise, so that the upper end of the ejector rod 34 ejects from the mold 8.It is convenient to eject and separate the glass product after bending and cooling forming, improving the disassembly efficiency of the glass product after bending and cooling forming. It is beneficial for the staff to place the softened glass to be bent on the mold 8 again, accelerating the efficiency of glass bending processing and forming. Moreover, the disassembly plate 33 first separates from the glass product after bending and forming, and then the ejector rod 34 completely ejects and disassembles the glass product. Compared with the existing method of directly removing the entire glass product from the mold 8, it can reduce the situations of cracking or breakage and difficult disassembly when disassembling the glass product, improving the quality and efficiency of glass bending processing. When the push plate 11 pushes the flexible heat-resistant belt 7 to slide leftward on the lifting frame 6, the upper surface of the flexible heat-resistant belt 7 will be continuously scraped by the cleaning strip 14. The cleaning strip 14 is under the pressure of the first spring 16 and will closely adhere to the upper surface of the flexible heat-resistant belt 7. The arranged cleaning strip 14 is convenient for uniformly cleaning the glass debris or impurities remaining on the upper end of the flexible heat-resistant belt 7, avoiding the situation that when the upper end of the flexible heat-resistant belt 7 is squeezed by the pressure roller 23 later, the uneven upper surface caused by the glass debris or impurities remaining on the upper end of the flexible heat-resistant belt 7 affects the uniform force application of the pressure roller 23 to press the upper end of the flexible heat-resistant belt 7, thus affecting the quality of glass processing and forming, and ensuring the quality of glass bending and forming processing. At the same time, when the push plate 11 pushes the flexible heat-resistant belt 7 to gradually slide leftward on the lifting frame 6, the top plate 22 will gradually approach and squeeze the pressing plate 21. The pressing plate 21 slides on the support plate 141, compressing the airbag 19 and the second spring 20, so that the gas in the airbag 19 is ejected through the connecting pipe 18 and the nozzle groove 17. The ejected gas is convenient for blowing off the glass debris and impurities scraped and concentrated on the right side of the upper end of the flexible heat-resistant belt 7 by the cleaning strip 14, reducing the situation of more glass debris and impurities remaining on the flexible heat-resistant belt 7. When the pressure roller 23 uniformly presses and rolls the upper end of the flexible heat-resistant belt 7, it will rotate on the connecting plate 24 under the action of friction. The arranged protection plates 28 on both sides are attached to both side surfaces of the pressure roller 23 under the action of the fourth spring 30. The arranged protection plates 28 are convenient for preventing glass debris from splashing and falling near the pressure roller 23 during the pressing work, causing unevenness on the surface of the flexible heat-resistant belt 7, and can also scrape off the softened glass fragments splashed and adhered to the surface of the pressure roller 23, avoiding the situation of unevenness on the surface of the pressure roller 23 during long-term work, thereby improving the quality of glass bending processing.
