Description

Technical Field

[0001] This invention belongs to the field of glass hot bending technology, specifically a glass hot bending machine and a glass hot bending method. Background Technology

[0002] Glass is an amorphous, non-metallic material, generally made from a variety of inorganic minerals as the main raw material and a small amount of auxiliary raw materials. Glass has the characteristics of wind insulation and light transmission, and is widely used in the construction industry. It belongs to the category of mixtures.

[0003] Currently, depending on the needs of different environments, glass hot bending machines are used to hot bend glass into curved surfaces, which is suitable for more buildings. During hot bending, the glass is placed on a bottom mold and sent into the hot bending machine, where the upper and lower molds are pressed together to form the shape.

[0004] When hot bending glass, the glass is usually loaded onto the bottom mold of the hot bending machine and then sent into the machine for hot pressing. However, since some glass is stored in the warehouse for a long time, the glass surface is prone to damage and cracks. The glass is easy to break after hot bending, which not only wastes resources, but also makes it difficult to clean up broken glass and affects the subsequent glass forming.

[0005] Therefore, the present invention provides a glass hot bending machine and a glass hot bending method. Summary of the Invention

[0008] Preferably, the detection assembly includes a detection frame and a detector; two detection frames are symmetrically fixed to the outside of the hot bending machine body; and two detectors are symmetrically fixed to both ends of the detection frame.

[0009] Preferably, the conveying assembly includes a second conveyor and placement plates; the second conveyor is located on the side of the detector away from the hot bending machine body; a plurality of placement plates are fixed to the outside of the second conveyor; and an anti-slip cloth is fixed to the top of the placement plate.

[0010] Preferably, the top of the second conveyor is symmetrically slidably connected with guide plates; a fixed frame is fixedly connected to one side of the top of the second conveyor near the guide plates; a double-threaded rod is rotatably connected inside the fixed frame, the two threads on the double-threaded rod are arranged in opposite directions, and the two guide plates are respectively connected to the two opposite threads; a turntable is fixedly connected to one end of the double-threaded rod near the fixed frame.

[0011] Preferably, an intercepting plate is fixedly connected to the top of the middle section of the second conveyor; a shovel plate is fixedly connected to the outside of the intercepting plate near the guide plate, and the bottom end of the shovel plate is in contact with the end face of the placement plate.

[0012] Preferably, the second conveyor is externally fixed with a plurality of elastic pads; the plurality of elastic pads are respectively fixed between the two placement plates.

[0013] Preferably, a fan is fixedly connected to the outside of the hot bending machine body near the two testing frames; air plates are symmetrically fixed to the outside of the detector; and multiple air plates are connected to the output end of the fan through the testing frames and air ducts.

[0014] Preferably, a heat-conducting pipe is fixedly connected inside the hot bending machine body and near the guide plate; the end of the heat-conducting pipe away from the hot bending machine body is connected to multiple air plates through a testing frame.

[0015] Preferably, sensors are installed inside the multiple elastic pads; an alarm is installed at the top of the second conveyor away from the guide plate, and the alarm is electrically connected to the multiple sensors.

[0016] A method for hot bending glass, applicable to the glass hot bending machine described above, comprises the following steps:

[0017] S1: First, multiple pieces of glass are fed separately and placed on multiple placement plates of the No. 2 conveyor for transport. The rotating turntable drives the double threaded rod to adjust the guide width of the two guide plates. The multiple pieces of glass are corrected when they pass through the guide plates. Then, the electric slider drives multiple vacuum suction cups to move above a single piece of glass. The output end of the electric cylinder extends downward to drive multiple vacuum suction cups to press against the single piece of glass. The vacuum pump inside the pump box works with multiple vacuum suction cups to adsorb the glass. The electric slider drives the glass to move and feed.

[0018] S2: Then, during the process of the glass being fed by the electric slider, the two detectors on the inspection frame simultaneously inspect the upper and lower surfaces of the glass. Glass with quality problems is sent back to the No. 2 conveyor by the electric slider, and then scraped off by the interceptor plate and transported between the two placement plates. Glass without quality problems is sent to the No. 1 conveyor by the electric slider, and then sent into the interior of the hot bending machine for hot bending.

[0019] S3: The hot-bent glass is adsorbed by another electric slider in conjunction with multiple vacuum suction cups. The adsorbed glass undergoes a second inspection. During the inspection process, a fan in conjunction with multiple air plates assists in cooling the glass. Finally, the glass is placed on the placement plate for conveying and unloading.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. The glass hot bending machine and method described in this invention use multiple vacuum suction cups to press and adsorb the top surface of the glass. As the electric slider slides along the bottom of the slide rail plate, the glass is loaded and unloaded. The detectors at both ends of the inspection frame inspect the passing glass to reduce secondary damage to broken glass. A second conveyor is used in conjunction with multiple placement plates to transport multiple pieces of glass. Two guide plates are set opposite each other to guide the glass placed on the placement plates. The intercepting plate and the scraper plate scrape off the defective glass on the placement plates, which plays a role in the recycling of defective glass.

[0022] 2. The glass hot bending machine and method described in this invention use an elastic pad fixed between two placement plates to buffer the falling defective glass. Air is blown from the output ends of a fan on both sides, reaching the top and bottom of the glass through multiple air plates, thus removing dust and cooling the glass. A heat pipe connects to a testing frame, transferring heat from inside the hot bending machine to multiple air plates for preheating the glass. A sensor triggers when broken glass is pressed against the surface; when the triggered sensor sends a proximity alarm, the alarm sounds in advance, alerting the user to the need for broken glass recovery.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] like Figures 1 to 4As shown in the embodiment of the present invention, a glass hot bending machine includes a hot bending machine body 1; a first conveyor 11 is installed inside the hot bending machine body 1; slide rail plates 12 are symmetrically fixed to both sides of the top of the hot bending machine body 1; electric sliders 13 are slidably connected to the bottom ends of the two slide rail plates 12; electric cylinders 14 are fixedly connected to the bottom ends of the electric sliders 13; a support frame 15 is fixedly connected to the output end of the electric cylinder 14; connecting plates 16 are fixedly connected to both sides of the bottom end of the support frame 15; the bottom ends of the two connecting plates 16 are fixedly connected to... The machine includes vacuum suction cups 17; a pump box 18 is fixedly connected to the outside of the support frame 15, and a vacuum pump is installed inside the pump box 18; two vacuum suction cups 17 are connected to the vacuum pump; a detection component is installed on the outside of the hot bending machine body 1, which is used to detect the quality of the glass; a conveying component is installed on the outside of the hot bending machine body 1, which is used for loading and unloading glass; when hot bending multiple pieces of glass, the multiple pieces of glass are placed on the conveying component, and multiple vacuum suction cups 17 at the loading point are used to deliver a single piece of glass. When the glass is lowered, the output end of the electric cylinder 14 drives the support frame 15 to press down. The connecting plate 16, together with multiple vacuum suction cups 17, presses against the top of the single piece of glass. The vacuum pump inside the pump box 18, together with the multiple vacuum suction cups 17, adsorbs the single piece of glass. As the electric slider 13 moves the glass, it slides and moves at the bottom of the slide rail plate 12. The glass is then sent to the bottom mold of the first conveyor 11. During the movement of the glass by the electric slider 13, it passes through the detection component. The detection component simultaneously detects damage and cracks on the top and bottom surfaces of the single piece of glass. If the glass... When breakage or cracks are detected, the electric slider 13 will send the glass back to the conveying assembly to continue conveying. If no breakage or cracks are detected, the electric slider 13 will send the glass to the first conveyor 11 and into the hot bending machine body 1 for internal hot pressing. After the hot-pressed glass is cooled once, it is sent to the unloading point, where the electric slider 13 sends the glass back to the conveying assembly for unloading. During the glass return process, it is detected again, which plays a role in checking the glass loading and unloading, reducing resource waste and minimizing the impact of broken glass on subsequent glass forming.

[0035] like Figures 1 to 3 As shown, the detection assembly includes a detection frame 2 and a detector 21; two detection frames 2 are symmetrically fixed to the outside of the hot bending machine body 1; two detectors 21 are symmetrically fixed to both ends of the detection frame 2; during the hot bending process of glass feeding, multiple pieces of glass are respectively fed between the two detectors 21 by the electric slider 13. The two detectors 21 supported by the detection frame 2 detect the top and bottom surfaces of a single piece of glass, thereby detecting the quality and condition of the glass and reducing the feeding of defective glass for hot bending. At the same time, when the glass is unloaded after hot bending, the two detectors 21 on the other side of the hot bending machine body 1 perform a second inspection on the hot-bent glass, thereby reducing the number of defective glass pieces that appear at the factory.

[0036] like Figure 1 , Figure 2 and Figure 5 As shown, the conveying assembly includes a second conveyor 3 and a placement plate 31; the second conveyor 3 is located on the side of the detector 21 away from the hot bending machine body 1; multiple placement plates 31 are fixed to the outside of the second conveyor 3; anti-slip cloth is fixed to the top of the placement plate 31; when conveying multiple pieces of glass, the multiple pieces of glass are placed on the second conveyor 3 for conveying and placed on multiple placement plates 31, and the anti-slip cloth on the placement plate 31 prevents the glass on the placement plate 31 from slipping and falling off, thereby achieving stable conveying of multiple pieces of glass.

[0037] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, guide plates 4 are symmetrically slidably connected to the top of the second conveyor 3; a fixed frame 41 is fixedly connected to one side of the top of the second conveyor 3 near the guide plate 4; a double threaded rod 42 is rotatably connected inside the fixed frame 41, the two threads on the double threaded rod 42 are arranged in opposite directions, and the two guide plates 4 are respectively connected to the two opposite threads; a turntable 43 is fixedly connected to one end of the double threaded rod 42 near the fixed frame 41; when multiple pieces of glass are placed on the placement plate 31 for conveying, some of the glass is prone to misalignment when placed and conveyed on the second conveyor 3, which affects the subsequent picking up and hot pressing effect of the glass. By using two guide plates 4 installed opposite to each other at the front loading point of the second conveyor 3, the rotation of the turntable 43 drives the double threaded rod 42 to rotate, and the two opposite threads on the double threaded rod 42 synchronously drive the two guide plates 4 to adjust the distance. When the two sides of the glass on the placement plate 31 come into contact with the side walls of the two guide plates 4, they can be squeezed and corrected by the two guide plates 4, reducing misalignment during the hot bending of the glass during conveying.

[0038] like Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, an intercepting plate 5 is fixedly connected to the top of the middle part of the second conveyor 3; a shovel plate 51 is fixedly connected to the outside of the intercepting plate 5 near the guide plate 4, and the bottom end of the shovel plate 51 is in contact with the end face of the placement plate 31; when the detector 21 detects that the glass is broken, the electric slider 13 sends the glass back to the placement plate 31 for continued conveying. When the broken glass is sent to the intercepting plate 5 by the second conveyor 3, the intercepting plate 5, together with the shovel plate 51, intercepts the glass placed on the placement plate 31 and shovels the broken glass into the gap between the two placement plates 31 for conveying, thereby playing the role of distinguishing and recycling the broken glass.

[0039] like Figure 1 , Figure 2 and Figure 5As shown, multiple elastic pads 6 are fixed to the outside of the second conveyor 3; the multiple elastic pads 6 are respectively fixed between two placement plates 31; when intercepting broken glass, since the shovel plate 51 directly shovels the broken glass, it is easy to cause secondary breakage of the glass. By using the elastic pads 6 fixed between the two placement plates 31 and close to the outside of one placement plate 31, after the glass is shoveled, the glass can be inclined at one end against the outside of one placement plate 31, and the other end can be pressed against the outside of the elastic pad 6, which plays a role in temporarily storing and recycling the glass. At the same time, the glass is inclined and pressed against the outside of the top of the elastic pad 6, which makes it easy to remove the glass from the inclined protruding end when unloading.

[0040] like Figures 1 to 3 As shown, a fan 7 is fixedly connected to the outside of the hot bending machine body 1 near the two inspection frames 2; air plates 71 are symmetrically fixed to the outside of the detector 21; multiple air plates 71 are connected to the output end of the fan 7 through the inspection frames 2 and air ducts; when feeding glass, some glass may have residual impurities, which may affect the hot bending effect of the glass. The fan 7 is fixed to the middle of the outside of the hot bending machine body 1. When the fan 7 is working, it blows air from the output ends on both sides of the fan 7 into the air duct, and then the air is transported to the inside of the inspection frame 2 through the air duct, and blown out at multiple detectors 21. The air blows air on the top and bottom of the glass passing through the detectors 21, reducing the adhesion of impurities on the glass and improving the hot bending effect of the glass. At the same time, after the glass is hot bent, the glass that has passed through the unloading point can be blown air again, thereby improving the cooling effect of the glass.

[0041] A heat-conducting pipe 8 is fixedly connected inside the hot bending machine body 1 and near the guide plate 4. The end of the heat-conducting pipe 8 away from the hot bending machine body 1 is connected to multiple air plates 71 through the inspection frame 2. When feeding glass, the heat-conducting pipe 8 connects the hot bending machine body 1 and an inspection frame 2. The heat inside the hot bending machine body 1 can be conducted to the inside of the inspection frame 2 through the heat-conducting pipe 8, and then hot air is blown onto the top and bottom of the glass from the multiple air plates 71, which can preheat the glass surface and reduce the possibility of breakage caused by direct hot bending of the glass. At the same time, the hot air blows on the top and bottom of the glass to improve the cleaning and dust removal effect of the glass.

[0042] like Figure 1 , Figure 2 and Figure 5 As shown, sensors 9 are installed inside the multiple elastic pads 6; an alarm is installed at the top of the second conveyor 3 away from the guide plate 4, and the alarm is electrically connected to the multiple sensors 9; when the broken glass is recycled, the broken glass is scooped off by the shovel plate 51 and pressed onto the elastic pads 6, and the pressure sensor 9 is triggered. The sensor 9 is a sensor that can be triggered by pressure. When the broken glass presses onto the sensor 9 and is conveyed close to the alarm, the alarm sounds in advance, thereby warning that the broken glass should be recycled, which serves as a warning to recycle the glass.

[0043] like Figure 8 As shown, a glass hot bending method is used, which is applicable to the glass hot bending machine described above. The steps of the method are as follows:

[0044] S1: First, multiple pieces of glass are fed separately and placed on multiple placement plates 31 of the second conveyor 3 for conveying. The rotating turntable 43 drives the double threaded rod 42 to adjust the guide width of the two guide plates 4. The multiple pieces of glass are corrected when they pass the guide plates 4. Then, the electric slider 13 drives multiple vacuum suction cups 17 to move above a single piece of glass. The output end of the electric cylinder 14 extends downward to drive multiple vacuum suction cups 17 to press against the single piece of glass. The vacuum pump inside the pump box 18 cooperates with multiple vacuum suction cups 17 to adsorb the glass. The electric slider 13 drives the glass to move and feed.

[0045] S2: Then, during the process of the electric slider 13 driving the glass to feed, the two detectors 21 on the detection frame 2 simultaneously detect the upper and lower surfaces of the glass that are passing by. The glass that is found to have quality problems is sent back to the second conveyor 3 by the electric slider 13, and then scraped off by the interceptor plate 5 and transported between the two placement plates 31. The glass that is not found to have quality problems is sent to the first conveyor 11 by the electric slider 13, and then sent into the interior of the hot bending machine 1 for hot bending.

[0046] S3: The hot-bent glass is adsorbed by another electric slider 13 in conjunction with multiple vacuum suction cups 17. The adsorbed glass is then subjected to a second inspection. During the inspection process, the fan 7, in conjunction with multiple air plates 71, assists in cooling the glass. Finally, the glass is placed on the placement plate 31 for conveying and unloading.

[0047] Working process: When hot bending multiple pieces of glass, the pieces of glass are placed on the conveying assembly. When a single piece of glass is fed to the bottom of the multiple vacuum suction cups 17 at the loading point, the output end of the electric cylinder 14 drives the support frame 15 to press down. The connecting plate 16, together with the multiple vacuum suction cups 17, presses down on the top of the single piece of glass. The vacuum pump inside the pump box 18, together with the multiple vacuum suction cups 17, adsorbs the single piece of glass. As the electric slider 13 moves the glass to slide displacement at the bottom of the slide rail plate 12.The glass is fed onto the bottom mold of conveyor 11. During the movement of the glass by the electric slider 13, it passes through a detection component. This component simultaneously detects breakage and cracks on both the top and bottom surfaces of each glass piece. If breakage or cracks are detected, the electric slider 13 returns the glass to the conveyor assembly for further transport. If no breakage or cracks are detected, the electric slider 13 sends the glass onto conveyor 11 for internal hot pressing in the hot bending machine body 1. After the hot-pressed glass is cooled once, it is sent to the unloading point, where the electric slider 13 returns the glass to the conveyor assembly for unloading. During the return process, the glass is inspected again, thus ensuring proper glass loading and unloading, reducing resource waste, and minimizing the impact of broken glass on subsequent glass forming. During the hot bending process of glass loading, multiple pieces of glass are fed by electric slider 13 to two detectors 21. The two detectors 21, supported by the inspection frame 2, inspect the top and bottom surfaces of each piece of glass to detect its quality and condition, reducing the amount of defective glass loaded for hot bending. Simultaneously, when unloading the glass after hot bending, the two detectors 21 on the other side of the hot bending machine 1 perform a second inspection, further reducing the number of defective pieces leaving the factory. When conveying multiple pieces of glass, they are placed on conveyor 3 and placed on multiple placement plates 31. Anti-slip cloths on the placement plates 31 prevent the glass from slipping and falling off, thus achieving stable conveying of multiple pieces of glass. When glass is conveyed on the placement plate 31, some glass may become misaligned during placement and conveying on the second conveyor 3, affecting subsequent glass pickup and hot pressing. Two guide plates 4 are installed opposite each other at the front loading point of the second conveyor 3. The rotation of the turntable 43 drives the double-threaded rod 42 to rotate. The two opposite threads on the double-threaded rod 42 synchronously drive the two guide plates 4 to adjust their spacing. When the glass on the placement plate 31 contacts the sidewalls of the two guide plates 4, it can be squeezed and corrected by the two guide plates 4, reducing misalignment during hot bending. When the detector 21 detects glass breakage, the electric slider 13 returns the glass to the placement plate 31 for continued conveying. The broken glass is then conveyed by the second conveyor 3 to the interception plate. At point 5, the intercepting plate 5, in conjunction with the shovel plate 51, intercepts the glass placed on the placement plate 31, shoveling the broken glass into the gap between the two placement plates 31 for conveying, thus separating and recycling the broken glass. When intercepting broken glass, the shovel plate 51 directly shovels the broken glass, which can easily cause secondary breakage. An elastic pad 6 is fixed between the two placement plates 31 and close to the outside of one placement plate 31. After the glass is shoveled, one end of the glass can be angled against the outside of one placement plate 31, while the other end is pressed against the outside of the elastic pad 6, serving as a temporary storage and recycling mechanism. Simultaneously, the angled pressure of the glass against the top of the elastic pad 6 facilitates removal of the glass from the angled, protruding end during unloading.

[0048] When the broken glass is recycled, the broken glass is scooped off by the shovel plate 51 and pressed onto the elastic pad 6, and the squeeze sensor 9 is triggered. The sensor 9 is a sensor that can be triggered by squeeze. When the broken glass presses onto the sensor 9 and is sent to the proximity alarm, the alarm will sound in advance, thereby warning that the broken glass should be recycled, and playing the role of warning the recycling of broken glass.

[0049] When feeding glass, some glass may have residual impurities, affecting the hot bending effect. A blower 7, fixed to the outer center of the hot bending machine body 1, blows air from both sides of the blower into the duct, which then delivers the air to the inspection frame 2. The air then flows to multiple detectors 21 and is blown out onto the top and bottom of the glass passing through the detectors 21, reducing impurities and improving the hot bending effect. After hot bending, the glass passing through the unloading area is blown again, improving cooling. During glass feeding, a heat pipe 8 connects the hot bending machine body 1 and an inspection frame 2. Heat from the hot bending machine body 1 is conducted to the inspection frame 2 via the heat pipe 8, and hot air is blown onto the top and bottom of the glass from multiple air plates 71, preheating the glass surface and reducing the risk of breakage during direct hot bending. The hot air also improves cleaning and dust removal.

S3: The hot-bent glass is adsorbed by another electric slider (13) in conjunction with multiple vacuum suction cups (17). The adsorbed glass is then subjected to secondary testing. During the testing process, the fan (7) in conjunction with multiple air plates (71) assists in cooling the glass. Finally, the glass is placed on the placement plate (31) for conveying and unloading.
