Description

Technical Field

[0001] This utility model relates to the field of glass product processing technology, specifically to a glass product annealing device equipped with a horizontal displacement mechanism. Background Technology

[0002] As an amorphous solid material, glass develops disordered thermal stresses due to uneven cooling rates after being melted and formed at high temperatures. These residual thermal stresses not only reduce the mechanical strength of glass products by more than 50%, but also significantly worsen their thermal stability, making them highly susceptible to cracking due to temperature fluctuations during subsequent processing or use. Therefore, the annealing process becomes a core step in ensuring the quality of glass products. Its core objective is to eliminate residual stress, optimize optical uniformity, and stabilize the internal microstructure through precise temperature control.

[0003] The prior art disclosure number CN116924665B discloses an annealing furnace for glass products, including a fixed base. The top of the fixed base is fixedly connected to the annealing furnace. A preheating chamber is fixedly connected to one side of the annealing furnace, and a cooling chamber is fixedly connected to the other side of the annealing furnace. A conveyor belt is provided at the bottom of the annealing furnace, and a fixing mechanism is fixedly connected to the side of the conveyor belt. The conveyor belt is fixedly connected to the fixed base. When annealing the glass products, the air supply mechanism blows the heat generated by the heating plate into the preheating chamber through the ventilation groove on one side wall of the annealing furnace. At this time, the temperature on the side of the preheating chamber will increase, and the hot air on the side wall of the preheating chamber will enter the fixing mechanism through the conveyor belt. The fixing mechanism can transfer heat to the bottom of the glass products while fixing them and clamping them, thereby fixing the glass products and heating them evenly.

[0004] The aforementioned existing technologies have several drawbacks: First, conveyor belts are mostly made of rubber to accommodate flexible conveying requirements. However, the core temperature inside the annealing furnace is often maintained at 400-600℃, far exceeding the heat resistance limit of rubber. Long-term use can easily lead to softening, deformation, or even adhesion of the conveyor belt to glass products. This not only requires frequent shutdowns for replacement, significantly shortening the equipment's lifespan, but also increases the risk of production interruption and maintenance costs. Second, the fixing mechanism directly fixes the glass products to the conveyor belt, resulting in an asymmetrical heating state with one side facing the heat source. This ultimately leads to uneven annealing of the glass products, incomplete elimination of residual stress, and some products still have optical distortion or localized embrittlement problems, making it difficult to meet the quality requirements of glass. Utility Model Content

[0005] The purpose of this invention is to provide a glass annealing device with a horizontal displacement mechanism, in order to solve the problems mentioned in the background art. In the prior art, the conveyor belt is mostly made of rubber to adapt to the flexible conveying requirements. However, the temperature in the core area of ​​the annealing furnace is often maintained at 400-600℃, which is far beyond the heat resistance limit of rubber. Long-term use can easily lead to softening, deformation, and even adhesion of the conveyor belt to the glass products. This not only requires frequent shutdowns for replacement, which greatly shortens the service life of the equipment, but also increases the risk of production interruption and maintenance costs. The fixing mechanism directly fixes the glass products to the conveyor belt, resulting in the products forming an asymmetrical heating state with one side facing the heat source. Ultimately, this results in uneven annealing of the glass products, incomplete elimination of residual stress, and some products still have optical distortion or local embrittlement problems, making it difficult to meet the quality requirements of glass.

[0006] To achieve the above objectives, the present invention provides the following technical solution: It includes: a workbench, the top of which is covered with an annealing heat preservation cover, an electric heater is provided on the inner wall of the annealing heat preservation cover, a driving component is provided inside the workbench, a displacement component is provided on the workbench, the displacement component is drivenly connected to the driving component, and several uniformly heated components are provided on the top of the displacement component.

[0007] Preferably, the top of the workbench has an installation groove in the middle, and the top of the workbench also has a pair of sliding grooves. The two sliding grooves are symmetrically arranged on both sides of the installation groove. The top of the workbench is symmetrically provided with a pair of upright plates, and each upright plate has a row of transmission teeth on its inner wall.

[0008] Preferably, the drive assembly includes a lead screw, which is movably mounted in a mounting slot via a pair of bearing seats. A mounting frame is provided on one side of the worktable, and a motor is mounted on the mounting frame. The transmission end of the motor is connected to one end of the lead screw via a coupling.

[0009] The above technical solution, driven by a lead screw, has high heat resistance, stable motion, and a longer service life.

[0010] Preferably, the displacement assembly includes a mounting plate disposed on the top of the workbench, a drive cylinder disposed at the bottom of the mounting plate, the drive cylinder being disposed in the mounting groove and sleeved on the outside of the lead screw, a lead screw nut disposed inside the drive cylinder, the lead screw nut being threadedly connected to the lead screw, and a slider disposed at the bottom of the mounting plate corresponding to the two sliding grooves.

[0011] By adopting the above technical solution, the mounting plate is moved by the cooperation of the screw and the nut, making the movement more stable. By setting the slider, the stability is further enhanced, ensuring the safety of glass products.

[0012] Preferably, the uniform heating component includes a rotating shaft, which is movably mounted on the top of the mounting plate via a bearing mounting seat. A mounting plate is provided on the top of the rotating shaft, and several rows of through holes are provided on the side wall of the mounting plate. A gear is provided on the rotating shaft at the position corresponding to the transmission teeth, and the gear meshes with the transmission teeth.

[0013] By adopting the above technical solution, during the displacement process, the gear meshes with the transmission gear, driving the rotating shaft to rotate, which enables the glass product to be heated evenly from all directions and improves the annealing quality.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model adopts a drive method with a lead screw and lead screw nut, which can stably adapt to the high temperature environment inside the annealing furnace. It fundamentally avoids the problems of the conveyor belt softening, deforming or sticking to products due to high temperature. At the same time, the lead screw transmission structure has stable movement, low wear rate and significantly extended service life, reducing downtime due to frequent replacement of conveyor components, reducing equipment operation and maintenance costs, and better adapting to the needs of continuous industrial production, ensuring efficient and uninterrupted annealing operations.

[0016] 2. This utility model uses a gear and transmission gear meshing design to synchronously drive the mounting plate to rotate during the movement of the mounting plate. This dual action of movement and rotation completely solves the problem of uneven heating caused by traditional fixed placement, ensuring that the temperature of each area of ​​the glass product is consistent, effectively eliminating residual stress, reducing optical distortion and local embrittlement, and especially meeting the annealing requirements of high-precision glass products, ensuring product quality stability.

[0017] 3. This utility model provides dual guiding support for the movement of the mounting plate through the cooperation of the slider and the chute in the displacement component, avoiding the deviation and shaking problems that are easy to occur in the operation of traditional conveyor belts. At the same time, the individual bearing design of the mounting plate for the product reduces the collision and friction between products. Throughout the entire conveying process, the glass products remain stable and will not shift even when rotating and heated, which greatly reduces product damage and loss caused by unstable equipment operation and reduces the waste of raw materials for enterprises.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-7 This utility model provides a technical solution: a glass product annealing device with a horizontal displacement mechanism, which includes a worktable 1, an annealing heat preservation cover 2, an electric heater 20, a drive component 3, a displacement component 4, and a uniform heating component 5.

[0028] The workbench 1 serves as the overall support base for the device. A mounting groove 10 for installing the drive components is provided in the middle of its top, and a pair of sliding grooves 11 are symmetrically provided on both sides of the top. A pair of upright plates 13 are also symmetrically fixed on the top of the workbench 1. A row of transmission teeth 14 for transmission is fixed on the inner wall of each upright plate 13. The annealing heat insulation cover 2 is completely covered on the top of the workbench 1 to form a closed annealing space. Electric heaters 20 for providing heat source are evenly fixed on the inner wall of the annealing heat insulation cover 2.

[0029] The drive assembly 3 includes a lead screw 31, a motor 30, and a mounting bracket 12. The lead screw 31 is movably mounted in the mounting groove 10 of the worktable 1 via a pair of bearing seats 32, ensuring that the lead screw 31 can rotate stably. The mounting bracket 12 is fixed to one side of the worktable 1, and the motor 30 is fixed on the mounting bracket 12. The transmission end of the motor 30 is fixedly connected to one end of the lead screw 31 via a coupling 33, realizing the stable transmission of power from the motor 30 to the lead screw 31. Compared with the traditional rubber conveyor belt, the lead screw 31 drive structure can withstand a heat temperature of over 300℃, which is fully suitable for the high-temperature environment inside the annealing furnace. It also has high motion accuracy and longer service life.

[0030] The displacement assembly 4 includes a mounting plate 40, a drive cylinder 41, a screw nut 42, and a slider 43. The mounting plate 40 is horizontally mounted on the top of the worktable 1. The drive cylinder 41 is fixed at the middle of its bottom. The drive cylinder 41 is embedded in the mounting groove 10 of the worktable 1 and sleeved on the outside of the screw 31. The screw nut 42, which is adapted to the screw 31, is fixed inside the drive cylinder 41. The screw nut 42 and the screw 31 are connected by threaded engagement. At the same time, sliders 43, which are adapted to slide in the sliding grooves 11 on both sides of the worktable 1, are fixed at the bottom of the mounting plate 40. Through the threaded engagement between the screw nut 42 and the screw 31, the mounting plate 40 can be driven to move horizontally along the worktable 1. During the movement, the slider 43 slides along the sliding groove 11, further limiting the offset of the mounting plate 40, ensuring the stability of the glass products during the conveying process, and avoiding product collision damage due to shaking.

[0031] Several uniformly heated components 5 are evenly distributed along the top of the mounting plate 40. Each component includes a rotating shaft 50, a mounting plate 52, a gear 54, and a bearing mounting seat 51. The bearing mounting seat 51 is fixed to the top of the mounting plate 40. The rotating shaft 50 is movably connected to the bearing mounting seat 51 through the bearing, ensuring that the rotating shaft 50 can rotate freely. The mounting plate 52 is fixed to the top of the rotating shaft 50, and several rows of through holes 53 are opened on its side wall to facilitate heat penetration and achieve uniform heating. The gear 54 is fixed to the outside of the rotating shaft 50, and the height of the gear 54 is the same as the height of the transmission teeth 14 on the two side upright plates 13 of the workbench 1. The gear 54 and the transmission teeth 14 can mesh and connect. When the mounting plate 40 moves, the gear 54 and the transmission teeth 14 mesh and drive the rotating shaft 50 to rotate synchronously, thereby realizing the continuous rotation of the mounting plate 52 and solving the problem of uneven heating caused by traditional fixed placement.

[0032] During the operation, the operator first places the glass products to be annealed one by one into several placement trays 52 on the top of the placement plate 40, ensuring that the products are placed in the center and avoiding displacement during rotation; then the electric heater 20 is started by the controller to preheat the temperature inside the annealing heat preservation cover 2 to the preset annealing temperature, and the annealing operation stage is entered after the temperature stabilizes.

[0033] Next, the operator starts the motor 30 through the controller. After the motor 30 is powered on, it drives the lead screw 31 to rotate clockwise through the coupling 33. Since the lead screw 31 is threadedly engaged with the nut 42 in the drive cylinder 41, the rotation of the lead screw 31 will be converted into the horizontal linear motion of the drive cylinder 41, which in turn drives the mounting plate 40 to move along the top of the workbench 1 towards the annealing insulation cover 2. During the movement, the slider 43 at the bottom of the mounting plate 40 slides synchronously along the slide groove 11 of the workbench 1 to ensure that the mounting plate 40 moves smoothly and avoids product shaking.

[0034] When the mounting plate 40 moves, the gear 54 on the rotating shaft 50 below the mounting tray 52 contacts and meshes with the transmission gear 14 on the upright plates 13 on both sides of the workbench 1; as the mounting plate 40 continues to move, the gear 54 begins to rotate under the meshing action of the transmission gear 14, thereby driving the rotating shaft 50 and the mounting tray 52 at the top to rotate synchronously (the rotation speed matches the moving speed of the mounting plate 40 to ensure that it can be fully heated with each rotation); at this time, the electric heater 20 in the annealing heat preservation cover 2 releases heat, and the heat penetrates to the product surface through the through hole 53 on the side wall of the mounting tray 52. ​​At the same time, because the mounting tray 52 continues to rotate, each surface of the product can be evenly contacted by the heat source.

[0035] The mounting plate 40 is moved out from the other side of the annealing insulation cover 2; the operator removes the annealed product; then the new product to be annealed is placed back into the mounting tray 52, and the controller controls the motor 30 to rotate counterclockwise. The motor 30 drives the lead screw 31 to rotate in the opposite direction, and then through the cooperation of the lead screw 42 and the drive cylinder 41, the mounting plate 40 is driven back to the initial position along the original path, and the next round of annealing operation cycle is entered to realize continuous production.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
