Description

Technical Field

[0001] This utility model relates to the field of material trays, and in particular to a material tray for glass kilns. Background Technology

[0002] Annealing is a crucial heat treatment process in the production of glass products. Its purpose is to eliminate residual stress inside the glass workpiece in order to improve its stability, mechanical strength and optical properties. Traditional glass annealing processes usually involve placing the glass workpiece directly on a fixed furnace bottom plate or support frame inside the furnace for heating and slow cooling.

[0003] However, existing annealing support methods have the following drawbacks: During the annealing process, the glass workpiece is in large-area contact with the furnace bottom plate or large support frame. Due to factors such as the heat flow distribution within the furnace and the uneven heating of the furnace bottom plate itself, this surface contact method creates an uneven heat conduction path, causing localized areas of the glass workpiece corresponding to the contact points to become "cold spots" or "hot spots," resulting in poor temperature field uniformity during the heating and holding processes. This uneven thermal history directly leads to incomplete stress relief within the glass, and may even generate new stresses, seriously affecting the annealing quality and causing defects such as product deformation, cracking, or substandard optical performance.

[0004] In the transfer process after annealing, the traditional method poses significant safety and quality risks. Operators need to use forklifts to remove the trays carrying high-temperature glass workpieces from the kiln and transport them to a designated area for stacking and buffering. Because the overall center of gravity of the racks and the workpieces on them is high, they are prone to shaking or even tipping over when encountering road bumps during forklift transportation. This can cause expensive glass workpieces to slip, collide, and break in batches, resulting in product damage. Utility Model Content

[0005] The purpose of this utility model is to provide a material tray for glass kilns in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a material tray for a glass kiln, comprising a tray and several feet equidistantly installed at its bottom, the top of the tray being open, and a sliding assembly for supporting glass workpieces being slidably arranged on its inner side, lifting and lowering assemblies for pushing the sliding assembly to move up and down on both sides of the tray in the width direction, and locking assemblies for limiting the glass workpieces inside the tray at two diagonal points in the length direction.

[0007] As a further description of the above technical solution: the sliding assembly includes a sliding plate that slides inside the tray, and a plurality of rods are fixedly installed at equal intervals on the top of the sliding plate, the rods being radially distributed on the top of the sliding plate.

[0008] As a further description of the above technical solution: the lifting and placing assembly includes two mounting slots symmetrically opened through both sides of the top width direction of the storage tray, both mounting slots are connected to the inner side of the storage tray, and a rotating rod is rotatably installed on the inner side of both mounting slots.

[0009] As a further description of the above technical solution: two connecting plates are symmetrically installed on the surface of the mounting groove. The two connecting plates are distributed in a V-shape on the outer surface of the rotating rod. A reinforcing block that is fixedly connected to the bottom end of the sliding plate is installed on the connecting plate closer to the sliding plate. A pedal is fixedly connected to one end of the connecting plate away from the sliding plate that extends through the mounting groove.

[0010] As a further description of the above technical solution: a hanging plate that is hinged to the bottom of the storage tray is installed on the side of the pedal away from the connecting plate.

[0011] As a further description of the above technical solution: the locking assembly includes a fixed rod and a threaded rod respectively installed at two opposite corners of the top of the tray. A stop rod is rotatably installed on the fixed rod. The end of the stop rod away from the fixed rod has a slot that matches the threaded rod. A nut for clamping the stop rod is threaded onto the outer surface of the threaded rod.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: During the annealing process of glass workpieces, the sliding plate inside the placement tray is pushed upward by the lifting assembly. The glass workpiece is placed on several rods radially distributed at the top of the sliding plate. After the sliding plate protrudes from the inner cavity of the placement tray, the glass workpiece is supported by the point-like support of the rods instead of the traditional surface contact. This fundamentally avoids the heat conduction interference caused by uneven temperature of the furnace bottom plate to the workpiece, ensuring that the temperature of each part of the workpiece is highly consistent during the heating and holding stages, and effectively suppressing the generation of residual stress. When the annealing process is completed and the glass workpiece is removed from the kiln by a forklift, the supporting effect of the lifting and placing components on the sliding plate is first released. After the sliding plate returns to the position of the workpiece, the overall center of gravity of the entire device is lowered, which greatly enhances the stability during forklift transportation. The upper port of the workpiece is limited by the locking components, which effectively prevents the glass workpiece from falling out of the opening of the workpiece during transportation or accidental collision, ensuring operational safety and product integrity.

[0015] 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.

[0016] like Figure 1 - Figure 2 As shown, this utility model provides a material tray for a glass kiln, comprising a tray 1 and several feet 2 equidistantly installed at its bottom. The top of the tray 1 is open, and a sliding assembly 4 for supporting glass workpieces is slidably arranged on its inner side. Lifting and lowering assemblies 3 are arranged on both sides of the tray 1 in the width direction to push the sliding assembly 4 for lifting and lowering. Locking assemblies 5 are arranged at two diagonal points in the length direction of the tray 1 to limit the glass workpieces inside. In actual use, when the device is placed in the kiln to anneal the glass workpiece, the stepping on the lifting component 3 will lift the sliding component 4 in the placement tray 1, which fundamentally avoids the heat conduction interference caused by uneven temperature of the furnace bottom plate on the glass workpiece, ensuring that the temperature of each part of the workpiece is highly consistent during the heating and holding stages, and effectively suppressing the generation of residual stress. When the annealing process is completed and the glass workpiece is removed from the kiln by a forklift, the supporting effect of the lifting component 3 on the sliding component 4 is first released. After the sliding component 4 returns to the position of the tray 1, the overall center of gravity of the whole device is lowered, which greatly enhances the stability during the forklift transportation process. At the same time, the upper port of the tray 1 is limited by the locking component 5, which effectively prevents the glass workpiece from falling out of the opening of the tray 1 during transportation or accidental collision.

[0017] Specifically, such as Figure 2 As shown, the sliding assembly 4 includes a sliding plate 41 that slides inside the tray 1. Several rods 42 are fixedly installed at equal intervals on the top of the sliding plate 41, and the rods 42 are radially distributed on the top of the sliding plate 41. The glass workpiece is supported by the rods 42 on the sliding plate 41. The point support of the glass workpiece replaces the traditional surface contact, which fundamentally avoids the heat conduction interference caused by uneven temperature of the furnace bottom plate and enhances the high temperature consistency of each part of the glass workpiece during the heating and heat preservation stages.

[0018] Furthermore, such as Figure 2 and Figure 4 As shown, the lifting and placing assembly 3 includes two mounting slots 31 symmetrically opened on both sides of the top width direction of the storage tray 1. Both mounting slots 31 are connected to the inner side of the storage tray 1, and a rotating rod 32 is rotatably installed on the inner side of both mounting slots 31. Two connecting plates 321 are symmetrically installed on the surface of the mounting groove 31. The two connecting plates 321 are distributed in a V-shape on the outer surface of the rotating rod 32. A reinforcing block 34 is installed on the connecting plate 321 closer to the sliding plate 41 and fixedly connected to the bottom end of the sliding plate 41. A pedal 33 is fixedly connected to one end of the connecting plate 321 away from the sliding plate 41 that extends through the mounting groove 31. A hanging plate 35 is hinged to the side of the pedal 33 away from the connecting plate 321 and is attached to the bottom of the storage tray 1.

[0019] When the pedal 33 is pressed down, the pedal 33 slides down, and the two connecting plates 321 on the outer surface of the rotating rod 32 push the sliding plate 41 together with the glass workpiece above it to bulge upward from the inside of the tray 1. This avoids uneven heat dissipation of the glass workpiece due to the obstruction of the inner wall of the tray 1 during the annealing process. After the pedal 33 moves downward, the hanging plate 35 hinged on one side of it is engaged with the bottom side of the storage tray 1 to prevent the sliding plate 41 from falling back into place. When it is necessary to retract the sliding plate 41 into the storage tray 1, step down on the pedal 33, and then kick the hanging plate 35 hanging on the lower side of the storage tray 1 upwards to disengage the hanging plate 35 from the bottom of the storage tray 1. Then slowly release the pedal 33, and the sliding plate 41 and the glass workpiece placed on it will slide into the storage tray 1.

[0020] Furthermore, such as Figure 3 and Figure 5As shown, the locking assembly 5 includes a fixed rod 51 and a threaded rod 52 respectively installed at two opposite corners of the top of the tray 1. A stop rod 53 is rotatably installed on the fixed rod 51. The end of the stop rod 53 away from the fixed rod 51 has a slot 531 that matches the threaded rod 52. A nut 54 for clamping the stop rod 53 is threaded on the outer surface of the threaded rod 52. When the device needs to be placed upright, first rotate the stop rod 53. The stop rod 53 rotates around the fixed rod 51 as the axis. After the slot 531 on its other end is hung on the threaded rod 52 at the opposite corner of the fixed rod 51, tighten the nut 54 to lock the stop rod 53, thereby blocking the opening of the tray 1 and preventing the glass workpiece from falling out of its opening after the tray 1 is erected.

[0021] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
