Description

Technical Field

[0001] This invention relates to the field of glass manufacturing equipment technology, specifically to a curved tempered glass forming equipment with replaceable molds and a method for replacing them. Background Technology

[0002] In the production of curved tempered glass, after the glass is heated and softened, it needs to be pressed and shaped into the required curved shape by forming equipment to obtain good optical quality and mechanical properties. Currently, most commonly used curved tempered glass forming equipment adopts a structure of a single press with a fixed mold. The same machine can only produce one specification of curved glass. When it is necessary to switch product specifications, the machine must be stopped to change the mold, which is time-consuming and seriously affects the continuity of the production line and the utilization rate of the equipment. Although some machines have multiple stations, there is a lack of flexible displacement mechanism between the stations, making it impossible to change molds and alternate production without stopping the machine. In addition, the upper and lower molds of existing forming equipment are mostly driven directly by hydraulic cylinders or air cylinders. The synchronization of the upper and lower molds is poor when the mold is closed, which easily leads to mold misalignment or uneven pressure, resulting in quality problems such as inconsistent curvature and surface ripples after the glass is formed. Summary of the Invention

[0003] This invention provides a curved tempered glass forming equipment and method with replaceable molds. By setting up two forming machines that can travel independently along the track, each forming machine is equipped with independent upper and lower molds and a drive system, as well as roller conveyor components, the invention solves the problems in the prior art where mold replacement requires machine shutdown, resulting in low production efficiency, inability to alternate continuous production, and poor synchronization of upper and lower molds affecting forming quality.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, two molding machines can travel independently along the track. When one molding machine needs to change the mold, it can travel along the track to the mold changing station / standby station to change the mold, while the other molding machine travels along the track to the molding station to take over production. This achieves mold changing without stopping the machine, greatly improving equipment utilization and production continuity. The track assembly ensures that the molding machine stops precisely on the track, meeting the positional accuracy requirements between the upper and lower molds and the conveyor rollers when the mold is closed. Each of the two molding machines has an independent drive system and mold, and the mold closing parameters (pressure, speed, holding time, etc.) can be adjusted separately according to process requirements to adapt to the molding requirements of different product specifications. 2. Each forming machine's upper and lower mold groups are driven by independent drive groups. Each drive group transmits power synchronously from a single power source to multiple lifting mechanisms through a commutator, drive shaft, and steering gear. This achieves multi-point synchronous lifting of the upper or lower mold, ensuring precise alignment and uniform pressure between the upper and lower molds during mold closing, thus guaranteeing consistent curvature and surface quality after glass forming. Each forming machine is equipped with an independent roller conveyor assembly. By rotating the main shaft, all rollers are driven to rotate in the same direction and at the same speed, ensuring the stability of the glass workpiece during transport and avoiding surface scratches or positional shifts caused by speed differences. At the same time, the gap between the rollers provides passage space for the lifting of the lower mold group, resulting in a compact and reasonable structure. Attached Figure Description

The first molding machine 1 achieves precise displacement control on the ground rail through the meshing transmission of the first motor 331, the first reducer 332, and the first output gear 333 with the first track 31; the second molding machine 2 achieves independent displacement control on the ground rail through the meshing transmission of the second motor 341, the second reducer 342, and the second output gear 343 with the first track 31, which facilitates the switching of the positions of the two molding machines when changing molds.

[0050] Specifically, the first reducer 332 is fixedly installed on one side of the bottom of the first frame 11, and the second reducer 342 is fixedly installed on one side of the bottom of the second frame 21. The bottom of the first frame 11 is provided with four first rollers 115, and the bottom of the second frame 21 is provided with four second rollers 215. Two first rollers 115 and two second rollers 215 are arranged to roll on the first track 31, and two first rollers 115 and two second rollers 215 are arranged to roll on the second track 32. The first forming machine 1 moves along the first rollers 115... The second molding machine 2 travels on the first track 31 and the second track 32 via the second roller 215. A transmission rack 311 is fixedly installed on one side of the first track 31. The first output gear 333 and the second output gear 343 are meshed and connected to the transmission rack 311. The first output gear 333 and the second output gear 343 are used to drive the first molding machine 1 and the second molding machine 2 while also preventing the first molding machine 1 and the second molding machine 2 from slipping on the track.

[0051] How track assembly 3 works: 1. When the first molding machine 1 needs to be moved, the first motor 331 starts, and after being reduced in speed and increased in torque by the first reducer 332, it drives the first output gear 333 to rotate. The first output gear 333 meshes with the transmission rack 311 fixedly installed on one side of the first track 31. Under the action of the rotation of the first output gear 333, the first molding machine 1 travels along the first track 31 and the second track 32 through the four first rollers 115 at the bottom. By controlling the direction and speed of the first motor 331, the leftward and rightward movement of the first molding machine 1 and the precise adjustment of the travel speed can be realized. 2. When the second molding machine 2 needs to be moved, the second motor 341 starts, and after being reduced in speed and increased in torque by the second reducer 342, it drives the second output gear 343 to rotate. The second output gear 343 meshes with the same transmission rack 311 for transmission. Under the action of the rotation of the second output gear 343, the second molding machine 2 travels along the first track 31 and the second track 32 through the four second rollers 215 at the bottom. By controlling the direction and speed of the second motor 341, the leftward and rightward movement of the second molding machine 2 and the precise adjustment of the travel speed can be realized. 3. Since the first output gear 333 and the second output gear 343 are driven by their respective independent motors and both mesh with the same transmission rack 311, the first molding machine 1 and the second molding machine 2 can travel independently without interfering with each other. When it is necessary to change the mold, one of the molding machines can travel to the end of the track to change the mold, while the other machine stays in the middle of the track to continue production, realizing mold changing without stopping the machine and improving production efficiency. The meshing transmission method of the first output gear 333, the second output gear 343 and the transmission rack 311 has higher transmission accuracy and anti-slip performance, which can ensure that the molding machine stops accurately on the track.

[0052] Please see Figure 2 , Figure 4 , Figure 7 , Figure 9 and Figure 10 The seventh drive group 43 includes a third motor 431, a third reducer 432, and a first rotating shaft 433 connected in sequence. The third reducer 432 and the first rotating shaft 433 are both mounted on the first frame 11. One end of each first roller 41 is connected to the first rotating shaft 433. The third motor 431 can drive the first rotating shaft 433 to rotate each first roller 41 so that the glass workpiece is conveyed along the tangential direction of the rotation of the top of the first roller 41. The eighth drive group 44 includes a fourth motor 441, a fourth reducer 442, and a second rotating shaft 443 connected in sequence. The fourth reducer 442 and the second rotating shaft 443 are both mounted on the second frame 21. One end of each second roller 42 is connected to the second rotating shaft 443. The fourth motor 441 can drive the second rotating shaft 443 to rotate each second roller 42 so that the glass workpiece is conveyed along the tangential direction of the rotation of the top of the second roller 42. The third motor 431, the third reducer 432, and the first rotating shaft 433 drive all the first rollers 41 to rotate synchronously, thus achieving stable conveying of glass workpieces on the first forming machine 1; the fourth motor 441, the fourth reducer 442, and the second rotating shaft 443 drive all the second rollers 42 to rotate synchronously, thus achieving stable conveying of glass workpieces on the second forming machine 2; the single rotating shaft drives all rollers to rotate synchronously, ensuring the consistency of conveying speed.

[0053] Specifically, the third reducer 432 is fixedly installed on one side of the first frame 11, and the fourth reducer 442 is fixedly installed on one side of the second frame 21. The first frame 11 has a pair of first rotating supports 116, and the second frame 21 has a pair of second rotating supports 216. The first rotating shaft 433 is installed on the first rotating support 116 near the third reducer 432, and the second rotating shaft 443 is installed on the second rotating support 216 near the fourth reducer 442. The output end of the third reducer 432, the front end of the first rotating shaft 433, the output end of the fourth reducer 442, and the front end of the second rotating shaft 443 are respectively provided with a first driving gear 4321, a first driven gear 4331, and a second driving gear 4421. The second driven gear 4431 and the seventh drive group 43 further include a first chain 434 meshing and drivingly connected to the first driving gear 4321 and the first driven gear 4331. The eighth drive group 44 further includes a second chain 444 meshing and drivingly connected to the second driving gear 4421 and the second driven gear 4431. The two ends of each first roller 41 are respectively mounted on the paired first rotating supports 116, and the end of each first roller 41 near the first rotating shaft 433 is connected to the first rotating shaft 433 via a conveyor belt. The two ends of each second roller 42 are respectively mounted on the paired second rotating supports 216, and the end of each second roller 42 near the second rotating shaft 443 is connected to the second rotating shaft 443 via a conveyor belt.

[0054] Working principle of roller conveyor assembly 4: 1. When the roller assembly 4 on the first forming machine 1 is working, the third motor 431 starts, and after being reduced in speed and increased in torque by the third reducer 432, it drives the first driving gear 4321 to rotate. The first driving gear 4321 transmits power to the first driven gear 4331 through the first chain 434. The first driven gear 4331 drives the first rotating shaft 433 to rotate on the first rotating support 116. The first rotating shaft 433 drives each first roller 41 to rotate in the same direction and at the same speed through several conveyor belts. The glass workpiece is conveyed along the tangential direction of the rotation of the top of the first roller 41. By controlling the direction and speed of the third motor 431, the conveying speed of the glass workpiece can be adjusted. 2. When the roller assembly 4 on the second forming machine 2 is working, the fourth motor 441 starts, and after being reduced in speed and increased in torque by the fourth reducer 442, it drives the second drive gear 4421 to rotate. The second drive gear 4421 transmits power to the second driven gear 4431 through the second chain 444. The second driven gear 4431 drives the second rotating shaft 443 to rotate on the second rotating support 216. The second rotating shaft 443 synchronously drives each second roller 42 to rotate in the same direction and at the same speed through several conveyor belts to transport the glass workpiece. The single rotating shaft synchronously drives all rollers to rotate through the conveyor belts, ensuring that the linear speed of each roller is completely consistent, avoiding scratches on the glass surface or conveying deviation caused by speed differences. Both ends of each roller are installed on paired rotating supports to ensure the parallelism and rotational stability of the rollers.

[0055] The working principle of the replaceable mold curved tempered glass forming equipment: 1. When the equipment is working, the first forming machine 1 first travels along the track to the middle position between the first track 31 and the second track 32, which is the forming station; the first upper module 14 is raised and lowered to the preset height under the drive of the first drive group 12; the first roller 41 is driven by the seventh drive group 43 to transport the heated and softened glass workpiece to the space between the first upper module 14 and the first lower module 15; then the second drive group 13 drives the first lower module 15 to rise; the first lower module 152 passes through the gap between several first rollers 41 and lifts the glass workpiece upward until the first lower module 152 cooperates with the first upper module 142 to clamp the glass workpiece and press it to form a curved tempered glass of the first specification; after forming, the first lower module 15 descends and puts the glass workpiece back onto the first roller 41; the first roller 41 transports the formed glass workpiece to the next station. 2. When mold replacement or maintenance is required, the fifth drive group 33 drives the first molding machine 1 to travel along the track to the end away from the second molding machine 2 (i.e., the mold changing station / standby station), where the first upper module 142 and the first lower module 152 on the first molding machine 1 can be replaced. At the same time, the sixth drive group 34 drives the second molding machine 2 to travel along the track to the middle position of the track (i.e., the molding station), where the second molding machine 2 takes over from the first molding machine 1 to continue production. The third drive group 22 drives the second upper mold group 24 to rise and fall to the preset height. The eighth drive group 44 drives the second roller 42 to transport the glass workpiece between the second upper mold group 24 and the second lower mold group 25. The fourth drive group 23 drives the second lower mold group 25 to rise for mold closing and pressure, processing the glass workpiece into a second type of curved tempered glass. After molding, it is transported to the next station. When the second molding machine 2 needs to be stopped, the first molding machine 1 can be driven to the middle of the track to take over from the second molding machine 2, realizing alternating production. The first molding machine 1 and the second molding machine 2 are independently controlled, and the mold closing pressure, mold closing speed and holding time can be adjusted separately according to the process requirements to adapt to the molding process requirements of different specifications of products.

The fifth drive group 33 drives the first molding machine 1 to the middle of the first track 31 and the middle of the second track 32, and the first drive group 12 drives the first upper mold group 14 to rise and fall to the preset height. Step S2. The seventh drive group 43 drives several first rollers 41 to transport the glass workpiece between the first upper mold group 14 and the first lower mold group 15. The second drive group 13 drives the first lower mold group 15 through several first rollers 41 and lifts the glass workpiece until the mold at the top of the first lower mold group 15 cooperates with the mold at the bottom of the first upper mold group 14 to process the glass workpiece into the first specification of curved tempered glass. The second drive group 13 drives the first lower mold group 15 to lift the glass workpiece until several first rollers 41 support the glass workpiece. The seventh drive group 43 drives several first rollers 41 to transport the glass workpiece to other equipment. Step S3. After repeating step S2 several times, the fifth drive group 33 drives the first molding machine 1 to the end of the first track 31 and the second track 32 away from the second molding machine 2; Step S4. The sixth drive group 34 drives the second molding machine 2 to the middle of the first track 31 and the middle of the second track 32, and the third drive group 22 drives the second upper mold 24 to rise and fall to the preset height. Step S5. The eighth drive group 44 drives several second rollers 42 to transport the glass workpiece between the second upper mold group 24 and the second lower mold group 25. The fourth drive group 23 drives the second lower mold group 25 through several second rollers 42 and lifts the glass workpiece until the mold at the top of the second lower mold group 25 cooperates with the mold at the bottom of the second upper mold group 24 to process the glass workpiece into a curved tempered glass of the second specification. The fourth drive group 23 drives the second lower mold group 25 to lower the glass workpiece until several second rollers 42 support the glass workpiece. The eighth drive group 44 drives several second rollers 42 to transport the glass workpiece to other equipment. Step S6. After repeating step S5 several times, the sixth drive group 34 drives the second molding machine 2 to the end of the first track 31 and the second track 32 away from the first molding machine 1.
