Description

Technical Field

[0001] This utility model relates to the technical field of glass tempering equipment, and in particular to a tempering furnace segmented cooling conveyor belt. Background Technology

[0002] Traditional tempering furnace cooling sections typically employ mesh or roller conveyor belt structures, which have significant drawbacks in actual production. For glass lids with curved surfaces, multiple glass pieces are prone to stacking and sticking together during transport, preventing the cooling airflow from evenly covering each glass surface. In particular, stress concentration occurs at the contact points between the curved parts of the glass lid and the conveyor belt, and traditional cooling methods struggle to effectively cool the bottom of the glass, resulting in significant differences in tempering strength across different parts of the product. This uneven cooling not only affects product quality stability but can also lead to defects such as stress spots on the glass surface. Existing conveyor belt systems lack effective slitting mechanisms and precise cooling control devices, failing to meet the production requirements of high-quality curved glass products. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to provide a tempering furnace segmented cooling conveyor belt that can avoid glass stacking and adhesion and ensure uniform cooling.

[0004] This utility model is implemented using the following method: a segmented cooling conveyor belt for a tempering furnace, comprising a conveyor belt, a gantry frame provided on the left end of the upper surface of the front and rear support plates of the conveyor belt, a strip-shaped opening provided on the cross plate of the gantry frame, a first motor provided in the strip-shaped opening, a first screw connected to the output end of the first motor, a first moving block spirally sleeved on the first screw, a moving plate provided on the upper surface of the first moving block, a telescopic cylinder embedded in the moving plate, a segmented plate provided at the end of the telescopic rod of the telescopic cylinder, and multiple electric suction cups provided at equal intervals on the lower surface of the segmented plate; a cooling hood provided on the right end of the upper surface of the conveyor belt, material inlets provided on both the left and right sides of the cooling hood, a limit member provided on the left side of the cooling hood, and cooling components provided on both the left and right ends of the upper surface of the cooling hood.

[0005] Furthermore, the limiting component includes a limiting plate, and strip-shaped grooves are provided at both the front and rear ends of the left side of the cooling cover. A second motor is provided in the strip-shaped grooves, and a second screw is connected to the output end of the second motor. A second moving block is spirally sleeved on the second screw, and the limiting plate is connected to the outer side of the second moving block.

[0006] Furthermore, the cooling component includes a circulating fan, and ventilation openings are provided at both the left and right ends of the cooling cover. The circulating fan is installed at the bottom of the ventilation opening. Multiple cooling pipes are arranged at equal intervals inside the ventilation opening, and the multiple cooling pipes are connected end to end. A dustproof net is installed at the top of the ventilation opening. The cooling pipes are connected to liquid inlet pipes and liquid outlet pipes.

[0007] The beneficial effects of this utility model are as follows: This utility model achieves glass segmentation and positioning through a segmentation plate and an electric suction cup, and combined with an adjustable limiting component and a circulating cooling structure, it solves the problems of glass stacking and adhesion and uneven cooling in traditional conveyor belts. It has the advantages of avoiding glass stacking and adhesion, ensuring uniform cooling, and improving product quality. Attached Figure Description

[0008] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0009] The present invention will be further described below with reference to the accompanying drawings.

[0010] Please see Figure 1 As shown, this utility model provides an embodiment: a segmented cooling conveyor belt for a tempering furnace, including a conveyor belt 1. A gantry frame 2 is provided on the left end of the upper surface of the front and rear support plates of the conveyor belt 1. A strip-shaped opening 21 is provided on the horizontal plate of the gantry frame 2. A first motor (not shown) is provided in the strip-shaped opening 21. The output end of the first motor is connected to a first screw 22. A first moving block 23 is spirally sleeved on the first screw 22. A moving plate 24 is provided on the upper surface of the first moving block 23. A telescopic cylinder 25 is embedded in the moving plate 24. A segmented plate 26 is provided at the end of the telescopic rod of the telescopic cylinder 25. A plurality of electric suction cups 27 are provided at equal intervals on the lower surface of the segmented plate 26. A cooling hood 3 is provided on the right end of the upper surface of the conveyor belt 1. A material inlet 31 is provided on both the left and right sides of the cooling hood 3. A limit member 4 is provided on the left side of the cooling hood 3. Cooling members 5 are provided on both the left and right ends of the upper surface of the cooling hood 3.

[0011] Among them, the gantry 2 refers to the support structure spanning the width of the conveyor belt, which can be implemented using a welded H-beam frame, used to support the moving components of the segmentation mechanism. The first screw 22 refers to the drive shaft with helical grooves, which can be implemented using a trapezoidal threaded rod, converting rotational motion into linear displacement. The segmentation plate 26 refers to a flat plate component with adsorption function, which can be implemented using an aluminum alloy plate, and the electric suction cups on the surface can generate negative pressure adsorption force. The cooling shroud refers to the sealed cavity surrounding the conveyor belt, which can be made of stainless steel plate bent into shape, and the left and right material inlet sizes can be adapted to accommodate products of different specifications. The limiting component 4 refers to an adjustable positioning device, which can be implemented using a sliding baffle structure, used to prevent stacked glass pot lids from entering the cooling shroud.

[0012] Specifically, when the glass lid enters the left end of the conveyor belt, the first motor drives the screw to move the moving block laterally, precisely aligning the slitting plate with the center of the product. A telescopic cylinder pushes the slitting plate downwards, and an electric suction cup adheres to the upper surface of the product before lifting it, transferring the single product to an adjacent station. The slitting product is then conveyed to the cooling hood via the conveyor belt. The forced airflow generated by the cooling components forms a circulation channel through the inlet, and the airflow passes over the upper and lower surfaces of the product before being discharged through the exhaust vent. The slitting plate transfers only one product at a time, ensuring that the products in the cooling station are arranged in a single layer. The limiting components can be adjusted according to the height of the glass lid to prevent deviation during transport.

[0013] Compared to existing technologies, the slitting mechanism achieves precise separation of products through a movable adsorption device, avoiding the uneven cooling problem caused by the stacking of multiple pieces on traditional conveyor belts. The cooling shroud adopts a double-sided air intake design, combined with circulating airflow channels at the top and bottom, ensuring sufficient heat dissipation even for the bottom contact area of ​​curved products. The continuous operation of the slitting and cooling processes shortens the production cycle compared to traditional segmented processing.

[0014] Through the above technical solution, this application effectively solves the problem of stacking and adhesion during the cooling process of curved glass products, ensuring that each product receives uniform cooling airflow coverage. The adjustable slicing and positioning mechanism adapts to the production needs of products of different sizes, and the dual-sided airflow circulation design significantly improves the heat dissipation efficiency of the curved structure. The integrated design of slicing and cooling processes ensures product quality while achieving continuous production.

[0015] Please continue reading. Figure 1 As shown, in one embodiment of the present invention, the limiting member 4 includes a limiting plate 41. The front and rear ends of the left side of the cooling cover 3 are provided with strip-shaped grooves 42. A second motor (not shown) is provided in the strip-shaped grooves 42. The output end of the second motor is connected to a second screw 43. A second moving block (not shown) is spirally sleeved on the second screw 43. The limiting plate 41 is connected to the outer side of the second moving block.

[0016] Among them, the strip groove 42 refers to the groove-shaped structure opened along the length of the cooling cover, which can be formed by machining or casting process, and is used to accommodate the motion components of the second motor and the second screw.

[0017] The second motor refers to the power device that drives the second screw to rotate. Specifically, it can be implemented by a stepper motor or a servo motor. The displacement of the second moving block is adjusted by controlling the direction and speed of the motor.

[0018] The second screw 43 refers to a transmission rod with a helical pattern, which can be implemented using a ball screw or a trapezoidal screw, converting rotary motion into linear motion through a threaded pair.

[0019] The second moving block refers to the threaded sleeve component that mates with the second screw. Specifically, it can be implemented using a copper alloy or steel nut, and is used to support the limiting plate and transmit displacement.

[0020] The limiting plate is a device that limits the height of the glass pot lids to prevent stacked glass pot lids from entering the cooling hood. The limiting plate is located at the material inlet of the cooling hood.

[0021] Specifically, when the glass lid enters the cooling shroud after being positioned by the dividing plate, the second motor drives the second screw to rotate, causing the second moving block to move laterally along the strip groove, thus moving it up and down. By adjusting the height of the limiting plate, it can accommodate glass lids of different diameters, preventing stress concentration caused by contact with the inner wall of the shroud during cooling. At the same time, the limiting plate and the conveyor belt form a guide channel, ensuring that the glass lid moves smoothly along the preset path and preventing uneven distribution of cooling airflow due to stacking.

[0022] Compared to existing technologies, traditional cooling sections use a fixed limiting structure, which cannot accommodate glass lids of different sizes. This solution, however, uses a motor-driven adjustable limiting plate to achieve dynamic position adjustment while maintaining a compact structure. In existing technologies, glass lids are prone to colliding with the limiting structure due to dimensional deviations. This solution, through flexible displacement control, actively avoids the glass edges, significantly reducing the risk of breakage.

[0023] Please continue reading. Figure 1 As shown, in one embodiment of the present invention, the cooling component 5 includes a circulating fan 51, and ventilation openings 52 are provided at both the left and right ends of the cooling cover 3. The circulating fan 51 is provided at the bottom of the ventilation opening 52, and multiple cooling pipes 53 are arranged at equal intervals inside the ventilation opening 52. The multiple cooling pipes 53 are connected end to end, and a dustproof net 54 is provided at the top of the ventilation opening 52. The cooling pipes 53 are connected to a liquid inlet pipe 55 and a liquid outlet pipe 56.

[0024] Among them, the circulating fan refers to a device that generates forced airflow by rotating blades. Specifically, it can be implemented using an axial flow fan to accelerate the airflow speed within the cooling shroud.

[0025] Cooling pipes refer to metal pipes through which cooling media flow. Specifically, copper spiral pipes can be used to reduce the temperature of the air flowing through the pipes through heat conduction.

[0026] Among them, the dustproof net refers to a filter device with a microporous structure, which can be made of stainless steel woven mesh, and is used to block external dust from entering the ventilation opening.

[0027] Specifically, airflow channels are formed inside the vents on both sides of the cooling shroud. When the circulating fan is activated, it pushes air across the surface of the cooling pipes. Multiple cooling pipes connected end-to-end form a continuous heat exchange surface, and the inlet pipe continuously supplies low-temperature coolant to maintain a constant low temperature on the pipe surface. As air flows through the cooling pipes, heat exchange occurs, creating a cool airflow. A dust filter prevents external impurities from entering the ventilation system. This structure, through the dual effects of forced convection and contact heat exchange, ensures that the cooling airflow evenly covers the glass surface.

[0028] Compared to existing technologies, traditional cooling devices rely solely on natural convection or unilateral airflow, which fails to ensure sufficient contact between the cooled air and the bottom area of ​​the curved glass surface. This solution utilizes bidirectional symmetrically arranged vents to create a circulating airflow, combined with a dense heat exchange surface formed by multiple cooling pipes, effectively solving the problem of insufficient cooling at the bottom of curved glass.

[0029] Through the above technical solution, this application achieves simultaneous and uniform cooling of the surface and bottom of glass products during the cooling process, avoiding differences in tempering caused by local temperature variations. The combination of the circulating fan and cooling pipes significantly improves cooling efficiency, and the dust filter extends the equipment maintenance cycle.

[0030] The circulating fan, conveyor belt, telescopic cylinder, electric suction cup, and motor in this utility model are all existing technologies, which are already clearly understood by those skilled in the art, and will not be described in detail here.

[0031] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
