Abstract

This invention discloses a dual-state cooling mechanism for a glass tempering furnace, relating to the field of glass tempering furnace technology. It further includes: a housing mounted on a conveying assembly; and a stabilizing assembly mounted on the housing, onto which the glass cup is snapped after being inverted. The stabilizing assembly includes a support portion and a cooling portion. The support portion has a first state and a second state as it moves within the cooling furnace with the conveying assembly: In the first state, the support portion supports the mouth and bottom of the glass cup, while the cooling portion dissipates heat from the inner cavity of the glass cup, enabling initial cooling and solidification. This invention, by inverting the glass cup and supporting it with a bottom and top support, prevents deformation risks due to its own weight, allowing for higher heating temperatures and thus achieving a superior tempering effect. Furthermore, the dual-state airflow of the cooling portion achieves simultaneous accelerated cooling of the inner and outer walls, significantly improving overall cooling efficiency while ensuring controllable temperature differences.

Description

Technical Field

[0001] This invention relates to the field of glass tempering furnace technology, specifically a dual-state cooling mechanism for a glass tempering furnace. Background Technology

[0002] In the field of glass tempering, the core logic of tempering process is to improve the strength and safety of glass through the physical treatment of "heating-rapid cooling": first, ordinary glass is heated to a plastic state close to its softening point, and then cooled quickly and evenly with high-pressure cold air. At this time, the glass surface forms a shrinking "compressive stress layer" due to rapid solidification. The interior cools more slowly and is constrained by the surface layer during subsequent shrinkage, thus forming a "tensile stress layer". After the stress is balanced, the overall strength of the glass can be significantly improved.

[0003] However, this process still faces significant technical bottlenecks in the processing of large-sized glass cups: On the one hand, when the large-sized cup body is heated to a near-plastic state, the lower part of the cup body is prone to deformation due to its own weight. To avoid this problem, it is usually necessary to reduce the heating temperature (below the conventional average value), but this will directly lead to insufficient performance of the tempered cup body; on the other hand, if the cup body is inverted and an internal support is set to reduce deformation, the principle is to reduce the force on the cup mouth to alleviate the influence of its own weight, which will cause new contradictions. In the inverted state, the internal cooling efficiency of the cup body is greatly reduced. Even if an independent air duct is added to cool the inner wall, its cooling speed is still far less than that of the outside. In order to avoid stress imbalance caused by excessive temperature difference between the inside and outside, it is necessary to slow down the external cooling speed, which ultimately leads to a reduction in overall cooling efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a dual-state cooling mechanism for a glass tempering furnace to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dual-state cooling mechanism for a glass tempering furnace, comprising a heating furnace, a cooling furnace, and a conveying assembly, wherein the conveying assembly is used to convey the glass sequentially through the heating furnace and the cooling furnace, and further comprising:

[0006] The housing is mounted on the conveying assembly;

[0007] A stabilizing component is provided on the housing. When the glass is inverted, it is fastened onto the stabilizing component. The stabilizing component includes a support part and a cooling part.

[0008] The support component has a first state and a second state as it moves within the cooling furnace along with the conveying assembly:

[0009] In the first state, the support part supports the mouth and bottom of the glass cup, and the cooling part dissipates heat from the inner cavity of the glass cup, so that the glass cup can achieve initial cooling and solidification.

[0010] In the second state, the drive component passively drives the support to move upward, and the support supports the bottom of the glass and the inner wall of the glass. At the same time, the air volume of the cooling section passively increases, and the glass cools down faster.

[0011] Preferably, the support includes a central tube, a base, a connecting column, a first elastic element, a fixing block, a top support, and a flipping element. The central tube is fixedly connected to the housing. The base is fixedly installed outside the central tube to support the bottom of the glass. The top support is slidably inserted into the upper part of the central tube. The upper end of the connecting column is connected to the top support. A second elastic element is provided between the connecting column and the top support. The lower end of the connecting column extends to the outside of the central tube. The fixing block is fixedly installed inside the central tube. The two ends of the first elastic element abut against the fixing block and the connecting column respectively, applying a thrust to the connecting column to move it away from the fixing block.

[0012] Preferably, the drive assembly includes a base, and one end of the base near the cooling furnace outlet has a ramp to guide height changes.

[0013] Preferably, the cooling unit includes an air inlet, an air outlet, a sealed door, a first air duct, and a second air duct. The air inlet is located in the middle of the central tube, the air outlet is located in the upper part of the central tube, the sealed door is fixedly installed on the connecting column, and the first and second air ducts are both located on the top support. The sealed door moves with the connecting column to control the opening and closing state of the air outlet.

[0014] Preferably, in the first state, the second air duct supplies air independently; in the second state, the first air duct, the second air duct, and the air outlet supply air simultaneously.

[0015] Preferably, the flipping component includes a roller, a swing arm, a base, and a follower ring. The follower ring is coaxial with the central tube and rotatably connected to the central tube. The base is fixedly installed on the follower ring. One end of the swing arm is rotatably connected to the base, and the other end of the swing arm is rotatably connected to the lower part of the roller. The upper part of the roller is hinged to the top support.

[0016] Preferably, the cooling furnace includes a furnace body, a distribution chamber, a first air outlet, a connecting box, a conveying pipe, a second air outlet, and a fan device. The fan device delivers cooling air to the distribution chamber through the pipe. The first air outlet is located at the bottom of the distribution chamber. The connecting box is located on both sides of the furnace body. The connecting box and the distribution chamber are connected through the conveying pipe. The second air outlet is located on the side of the connecting box facing the shell.

[0017] Preferably, the housing has through holes on both sides, which are connected to the second air vent when the housing moves to the corresponding position.

[0018] Preferably, the conveying component is a chain conveyor, with the housing fixedly connected to the conveying chain to move synchronously with the conveying chain.

[0019] Preferably, it also includes robotic arms, which are respectively set at the beginning and end of the conveying assembly, for simultaneously loading and unloading multiple glass cups.

[0020] In the above technical solution, the present invention provides a dual-state cooling mechanism for a glass tempering furnace. By inverting the glass and supporting it with a bottom support and a top support, the risk of deformation caused by its own weight is prevented, allowing for higher heating temperatures and thus obtaining a better tempering effect. The cooling section delivers air to the inner cavity of the glass, reducing the temperature difference between the inside and outside and avoiding stress imbalance caused by excessive temperature difference. After initial cooling, a single top support is used for support, and the first air passage, the second air passage, and the air outlet simultaneously enhance air delivery, achieving simultaneous accelerated cooling of the inner and outer walls. Under the premise of ensuring controllable temperature difference, the overall cooling efficiency is greatly improved. Attached Figure Description

[0036] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] Please see Figure 1-13 The present invention provides a dual-state cooling mechanism for a glass tempering furnace, comprising a heating furnace 4, a cooling furnace 5, and a conveying assembly 1. The conveying assembly 1 is used to convey a glass 6 through the heating furnace 4 and the cooling furnace 5 in sequence, and also includes;

[0038] Housing 2, which is mounted on conveying assembly 1;

[0039] The stabilizing component 3 is provided on the housing 2. The glass cup 6 is snapped onto the stabilizing component 3 after being inverted. The stabilizing component 3 includes a support part and a cooling part.

[0040] The support portion has a first state and a second state as it moves within the cooling furnace 5 along with the conveying assembly 1:

[0041] In the first state, the support part supports the mouth and bottom of the glass cup 6, and the cooling part dissipates heat from the inner cavity of the glass cup 6, so that the glass cup 6 can achieve initial cooling and solidification.

[0042] In the second state, the drive component 7 passively drives the support part to move upward, and the support part supports the bottom of the glass cup 6 and the inner wall of the glass cup. Simultaneously, the air volume of the cooling part passively increases, and the glass cup 6 cools down faster.

[0043] In this embodiment, the inverted glass cup 6 is sequentially conveyed to the heating furnace 4 for heating and the cooling furnace 5 for cooling and tempering by the conveying component 1. Finally, the material is unloaded by the robot arm. The core solution is to solve the problems of easy deformation during heating, large temperature difference during cooling, and low efficiency of large-sized glass cups by cooperating with the dual-state support of the stabilizing component 3 and the dual-state air supply of the cooling part.

[0044] By using an inverted support, the glass cup 6 is inverted and fastened to the stabilizing component 3. The bottom support 311 of the support part supports the mouth of the cup and the top support 38 supports the bottom of the cup. This design can prevent the cup body from sagging and deforming due to its own weight when heated, thus allowing for higher heating temperatures (temperatures close to the softening point), laying the foundation for subsequent tempering performance improvement.

[0045] When the glass cup 6 initially enters the cooling furnace 5, it is in a low support position. The top support 38 and the bottom support 311 support the bottom and mouth of the cup, respectively. At this time, the cooling section cools the inner wall of the glass cup 6 so that the glass cup 6 can be cooled and solidified. In order to ensure the stability of the glass cup 6 at this time, the air volume needs to be limited, and the cooling efficiency is insufficient.

[0046] After moving forward, it enters the second state. At this time, as the temperature of the glass cup 6 drops and solidifies, the top support 38 will move upward so that the mouth of the glass cup is separated from the bottom support 311. In this way, the airflow of the glass cup 6 is smoother. During the upward movement, the airflow of the cooling section will be passively increased. By increasing the airflow, the cooling efficiency of the inner wall of the glass cup 6 is accelerated, and the overall cooling efficiency is greatly improved while ensuring that the temperature difference is controllable.

[0047] In another embodiment of the present invention, please refer to Figure 2-4The support includes a central tube 31, a base 311, a connecting column 33, a first elastic element 34, a fixing block 35, a top support 38, and a flipping element 39. The central tube 31 is fixedly connected to the housing 2. The base 311 is fixedly installed outside the central tube 31 to support the bottom of the glass 6. The top support 38 is slidably inserted into the upper part of the central tube 31. The upper end of the connecting column 33 is connected to the top support 38. A second elastic element 331 is provided between the connecting column 33 and the top support 38. The lower end of the connecting column 33 extends to the outside of the central tube 31. The fixing block 35 is fixedly installed inside the central tube 31. The two ends of the first elastic element 34 abut against the fixing block 35 and the connecting column 33 respectively, applying a pushing force to the connecting column 33 to move it away from the fixing block 35.

[0048] The support section serves as the core structure for stable support and state switching of the glass cup. The central tube 31 is fixedly connected to the housing 2. The bottom support 311 is fixedly installed outside the central tube 31, its shape adapted to the bottom of the glass cup 6 and having slots for airflow. It continuously supports the rim of the cup during the first cooling state, forming the base point for support. The top support 38 is slidably inserted into the upper part of the central tube 31, its upper part contacting the bottom of the glass cup 6, and its lower part inserted into the connecting post 33. The lower end of the connecting post 33 extends to the outside of the central tube 31, and through cooperation with the drive assembly 7, it enables the top support 38 to move up and down and rotate. The fixing block 35 is fixedly installed inside the central tube 31, serving as the lower support point of the first elastic element 34, and in its natural state, it applies pressure to the connecting post 33. A downward thrust is applied to keep the top support 38 in its initial position, so as to achieve synchronous lifting of the top support 38 and the bottom support 311. The flipping part 39 will passively unfold in the second state to support the inner wall of the cup. This structural design makes the support part in the first state, with the top support 38 in a low position under the action of the first elastic member 34, which cooperates with the bottom support 311 to form a stable support for the cup mouth and the cup bottom. In the second state, the connecting column 33 is driven to move upward, causing the top support 38 to rise. The roller 391 of the flipping part 39 opens outward to support the inner wall of the cup. In the second state, it helps to maintain the stability of the glass cup 6. Thus, the dual-state support is carried out when the glass cup 6 is under different temperature conditions, in order to cooperate with different air volume, to achieve accelerated cooling of the cup wall of the glass cup 6.

[0049] In the embodiments of the present invention, please refer to Figure 4 The drive assembly 7 includes a base 71, and the end of the base 71 near the outlet of the cooling furnace 5 is provided with an inclined surface to guide the height change.

[0050] The base 71 of the drive assembly 7 is fixedly connected to the frame of the conveying assembly 1 as the mounting base. The inclined surface at the end near the inlet of the cooling furnace 5 can guide the gear 73 and the connecting column 33 to change height when the conveying assembly 1 drives the housing 2 and the stabilizing assembly 3 to move, so that the glass cup 6 is displaced upward and the cup mouth is separated from the base 311 to meet the requirement of a larger air volume.

[0051] In another embodiment of the present invention, see reference Figure 13 It also includes a rack 72 and a gear 73. The rack 72 is fixedly mounted on the base 71, and the gear 73 is fixedly mounted on the outside of the connecting column 33, and the gear 73 is adapted to mesh with the rack 72.

[0052] The rack 72 is fixedly mounted on the base 71, and the gear 73 is fixed outside the connecting column 33 and meshes with the rack 72. When the conveying assembly 1 drives the connecting column 33 and the gear 73 to move, the gear 73 meshes with the rack 72. While moving in the conveying direction, it will rotate due to the fixation of the rack 72. At the same time, under the action of the inclined surface of the base 71, the connecting column 33 passively moves upward, realizing the synchronous upward movement and rotation of the connecting column 33, thereby driving the support part and switching the support part from the first state to the second state. The synchronous rotation makes the glass cup 6 cool more evenly.

[0053] In the embodiments of the present invention, please refer to Figure 2-4 The cooling unit includes an air inlet 32, an air outlet 36, a sealed door 37, a first air duct 381, and a second air duct 382. The air inlet 32 ​​is located in the middle of the central tube 31, and the air outlet 36 is located in the upper part of the central tube 31. The sealed door 37 is fixedly installed on the connecting column 33. The first air duct 381 and the second air duct 382 are both located on the top support 38. The sealed door 37 moves with the connecting column 33 to control the opening and closing state of the air outlet 36. In the first state, the second air duct 382 discharges air alone; in the second state, the first air duct 381, the second air duct 382, ​​and the air outlet 36 discharge air simultaneously.

[0054] The air inlet 32 ​​of the cooling section is located in the middle of the central tube 31, used to introduce cooling air from the housing 2 into the central tube 31. The air outlet 36 is located at the top of the central tube 31, serving as one of the channels for the cooling air inside the central tube to be sent outwards. The airtight door 37 is fixedly installed on the connecting column 33 and moves synchronously with the up and down movement of the connecting column 33, thereby controlling the opening and closing of the air outlet 36. In the first state, because the airtight door 37 blocks the air outlet 36, the top support 38 is in the corresponding low position, and the cup opening is obstructed by the bottom support 311, in order to avoid the large air volume causing the glass to... When the glass cup 6 is displaced, air can only be vented from the second air duct 382. This is only used to achieve initial cooling (making the temperature significantly lower than the softening temperature). After the glass cup 6 solidifies, it enters the second phase. In the second phase, the drive assembly 7 moves the connecting column 33 upward, and the airtight door 37 moves upward to open the air outlet 36. The top support 38 moves upward simultaneously to open the first air duct 381. Therefore, the first air duct 381, the second air duct 382, ​​and the air outlet 36 vent air simultaneously, achieving a passive increase in air volume. The large air volume can effectively improve the cooling efficiency of the inner wall of the glass cup 6.

[0055] In another embodiment of the present invention, please refer to Figure 8-12 The flipping component 39 includes a roller 391, a swing arm 392, a base 393, and a follower ring 312. The follower ring 312 is coaxial with the central tube 31 and rotatably connected to the central tube 31. The base 393 is fixedly installed on the follower ring 312. One end of the swing arm 392 is rotatably connected to the base 393, and the other end of the swing arm 392 is rotatably connected to the lower part of the roller 391. The upper part of the roller 391 is hinged to the top support 38.

[0056] The follower ring 312 is coaxial with and rotatably connected to the central tube 31, maintaining a stable relative position with the central tube. The base 393 is fixedly installed on the follower ring 312, serving as the connection base point for the swing arm 392. The follower ring 312 can rotate synchronously with the swing arm 392. One end of the swing arm 392 is rotatably connected to the base 393, and the other end is rotatably connected to the lower part of the roller 391, forming a movable linkage structure. The upper part of the roller 391 is hinged to the top support 38, and its position and posture change with the movement of the top support 38. In the first state, the top support 38 is in a low position, and the roller 391 is pulled by the swing arm 392 to maintain a closed state (not in contact with the inner wall of the cup). At this time, the support depends on the top support 38 and the bottom support 31. 1; In the second state, the top support 38 moves upward with the connecting column 33, causing the upper part of the roller 391 to move upward synchronously. The swing arm 392 swings outward around the base 393, causing the roller 391 to open and fit against the inner wall of the cup, thus achieving contact with the inner wall of the cup. At this time, the roller 391 cannot continue to unfold, while the connecting column 33 still has the tendency to move upward. Therefore, the second elastic element 331 will be compressed to ensure that the connecting column 33 moves upward smoothly and that the gear 73 can reach the predetermined meshing position. When the connecting column 33 rotates, it synchronously drives the top support 38 to rotate, and the roller 391 will also revolve around the central tube 31, thereby driving the glass cup 6 to rotate, which, together with the air supply of the cooling section, improves the cooling uniformity.

[0057] This embodiment also has another technical effect: during the cooling process, some glass cups 6 will develop cracks. Because the second elastic element 331 exerts an upward thrust on the top support 38, the roller 391 will compress the glass cups 6. Thus, when the glass cups 6 have cracks, the squeezing action of the roller 391 can cause the defective glass to break and be automatically removed.

[0058] In an embodiment of the present invention, the cooling furnace 5 includes a furnace body 51, a flow distribution chamber 52, a first air outlet 521, a connecting box 53, a conveying pipe 54, a second air outlet 55, and a fan device 56. The fan device 56 delivers cooling air to the flow distribution chamber 52 through the pipe. The first air outlet 521 is located at the bottom of the flow distribution chamber 52. The connecting box 53 is located on both sides of the furnace body 51, and the connecting box 53 and the flow distribution chamber 52 are connected through the conveying pipe 54. The second air outlet 55 is located on the side of the connecting box 53 facing the housing 2. Through holes are provided on both sides of the housing 2, and the through holes communicate with the second air outlet 55 when the housing 2 moves to the corresponding position.

[0059] The components of the cooling furnace 5 achieve internal and external cooling of the glass cup 6 through the air duct design. The furnace body 51 provides a closed space for cooling. The fan device 56 is the power source for the cooling air, which is delivered to the distribution chamber 52 through pipelines. The distribution chamber 52 divides the cooling air. One part of the cooling air is blown directly into the furnace from the first air outlet 521 to cool the top and outside of the glass cup 6 on the conveying assembly 1. The other part of the cooling air is delivered to the connecting boxes 53 on both sides of the furnace body 51 through the conveying pipe 54, and then from the connecting boxes 53 towards the second air outlet 53 on the side of the shell 2. Air is delivered from vent 55 to cool the inner wall of the glass cup 6. When the conveying component 1 moves the housing 2 to a specific position in the cooling furnace 5 and stops, the moving path and stopping position of the conveying component 1 are precisely designed to ensure that when the housing 2 stops in a specific cooling area, the through holes on both sides are precisely aligned with the through holes of the housing 2, and only communicates with the second air vent 55 in the corresponding cooling area. At this time, the cooling air delivered by the connecting box 53 can enter the interior of the housing 2 through the through holes, which cooperates with the internal cavity cooling of the stabilizing component 3 to form a cooling system that works synergistically inside and outside.

[0060] In an embodiment of the present invention, the conveying component 1 is a chain conveyor, and the housing 2 is fixedly connected to the conveying chain to move synchronously with the conveying chain.

[0061] The conveying assembly 1 uses a chain conveyor, with the conveyor chain serving as the core transmission structure. The housing 2 is fixedly connected to the conveyor chain, allowing the housing 2 to move synchronously with the cyclical movement of the conveyor chain. This connection and transmission design drives the stabilizing assembly 3 on the housing 2 and the glass cup 6 fastened to the stabilizing assembly 3 to sequentially pass through the heating furnace 4 and the cooling furnace 5 along a preset path, achieving continuous conveying of the glass cup tempering process and ensuring the continuity and stability of the processing flow.

[0062] Preferably, it also includes robotic arms, which are respectively set at the beginning and end of the conveying assembly 1, for simultaneously loading and unloading multiple glass cups 6.

[0063] The first robotic arm inverts and attaches a batch of 6 glass cups to be processed onto the stabilizing component 3 in its initial position, completing the loading process. The second robotic arm removes the finished products in batches from the stabilizing component 3 after the glass cups 6 have undergone tempering, completing the unloading process. This synchronous operation design is compatible with the conveying rhythm of the chain conveyor, reducing the time interval between individual loading and unloading operations, and effectively improving the overall automation level and production efficiency.

[0064] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
