However, the traditional annealing lehr roller transmission mode often has many problems when facing roller failure or maintenance needs.

[0003] In the prior art, the annealing lehr roller is generally independently set by multiple roots, and each roller is driven to run by an independent driving unit. This transmission mode performs well when the roller is normally running, but when one or more rollers are stopped due to failure or maintenance needs, problems will follow. Due to the lack of effective linkage mechanism between the rollers, the stopped roller cannot be driven by other normally running rollers, resulting in the glass being damaged in the transmission process due to the friction between the lower surface and the stopped roller, and even causing serious process accidents such as glass plate surface rupture. This not only affects the quality of the glass product, but also greatly reduces the continuity and safety of the production line.

[0004] In addition, the traditional annealing lehr roller transmission mode also has many inconveniences when repairing and replacing the failed roller.

[0052] Embodiment 2

[0053] In another preferred embodiment, on the basis of the above-mentioned embodiment 1, the utility model provides a novel chain wheel auxiliary transmission device, aims at solving the bending problem of the annealing furnace roller bed of the float glass factory caused by temperature difference in the use process, and the stop rotation problem caused by roller bed failure or maintenance, and the following is a detailed description of the specific implementation manner of the utility model.

[0054] The embodiment details the structure of the chain wheel auxiliary transmission device and the working principle after being installed at the shaft end of the annealing furnace roller bed.

[0055] First, the device consists of bolt 1, pressure sleeve 2, expansion sleeve 3, sleeve 4, sprocket 5, screw 6, flat key 7, nut 8, flat washer 9, spring washer 10, pin 11, and crank handle 12. These components work together to achieve rapid correction and transmission of the annealing kiln roller table.

[0056] During installation, the device is first placed in the end hole of the annealing kiln roller conveyor shaft; then, by tightening the nut 8, the bolt 1 simultaneously presses the pressure sleeve 2, and the pressure sleeve 2 then presses the expansion sleeve 3, causing the expansion sleeve 3 to expand and tighten against the annealing kiln roller conveyor; in this way, the device and the roller conveyor are connected as one unit and can operate synchronously.

[0057] To address the issue of roller conveyor bending, the crank handle 12 is fitted onto the device shaft end and the pin 11 is inserted for fixation. At this point, the crank handle 12 can be manually turned to drive the roller conveyor to rotate rapidly. The roller conveyor is straightened by rapidly turning the crank. After straightening is completed, the nut 8 is loosened, and the bolt 1, pressure sleeve 2, and expansion sleeve 3 are immediately in a loosened state. The expansion sleeve 3 disengages from the inner hole of the roller conveyor, and the device is separated from the roller conveyor. After removing the chain, the device can be removed from the roller conveyor.

[0058] To address the issue of roller conveyor malfunctions and shutdowns, this device is installed on multiple roller conveyors, with a chain attached to the sprocket 5. In this way, when one or more roller conveyors stop due to malfunction or maintenance, the normally operating roller conveyors can drive the stopped roller conveyors to continue rotating via chain transmission, achieving coordinated operation of multiple roller conveyors. After the roller conveyor malfunction is resolved or maintenance is completed, the device can be removed by loosening the nut 8.

[0059] Example 3

[0060] In another preferred embodiment, based on the above embodiments 1 and 2, this embodiment demonstrates the application and adaptability of the sprocket-assisted transmission device on roller conveyors of different specifications of annealing kilns.

[0061] To verify the wide applicability of this utility model, we selected annealing kiln roller conveyors of different diameters and lengths for testing. By adjusting the tightness of bolts 1 and nuts 8, and selecting appropriate expansion sleeve 3 dimensions, we found that the device can fit tightly onto roller conveyors of different specifications and achieve a stable transmission effect.

[0062] In addition, we tested the performance of the device under different temperature conditions; the results showed that even under high or low temperature conditions, the device can still maintain good working condition and will not have a negative impact on the operation of the annealing kiln roller conveyor.

[0063] In a preferred embodiment, the clamping assembly includes a bolt 1, on which a pressure sleeve 2, an expansion sleeve 3, a sleeve 4, and a nut 8 are sequentially fitted. The clamping assembly is positioned within the end hole of the annealing kiln roller conveyor shaft. By tightening the nut 8, the bolt 1 clamps the pressure sleeve 2, which in turn clamps the expansion sleeve 3. The expansion sleeve 3 then expands and presses against the annealing kiln roller conveyor, achieving integrated and synchronous operation of the device and the roller conveyor. This configuration not only ensures the stability and reliability of the clamping assembly but also effectively prevents loosening and displacement of the annealing kiln roller conveyor during operation, improving the overall operating efficiency and safety of the annealing kiln and reducing maintenance and replacement costs.

[0064] In a preferred embodiment, the expansion sleeve 3 is made of elastic material, which expands radially and fits tightly against the inner hole of the annealing kiln roller conveyor when compressed. This configuration ensures that the expansion sleeve 3 can fit evenly and tightly against the inner wall of the annealing kiln roller conveyor when subjected to external pressure, thus guaranteeing the stability of the connection and avoiding damage caused by stress concentration, effectively improving the service life of the equipment.

[0065] In a preferred embodiment, the transmission assembly includes a sprocket 5 and a chain. The sprocket 5 is fixedly mounted on the clamping assembly and is used to connect multiple annealing kiln rollers via the chain to achieve synchronous transmission. This configuration effectively ensures the stability and synchronization of the annealing kiln rollers during operation, improves the overall operating efficiency of the equipment, reduces the failure rate caused by asynchronous transmission, and enhances the reliability and durability of the equipment.

[0066] In the preferred embodiment, the sleeve 4 is inserted and pressed tightly onto the other end of the expansion sleeve 3, and a sprocket 5 is fitted onto the sleeve 4. The sleeve 4 supports the sprocket 5 and makes it coaxially installed with the annealing kiln roller conveyor. The above arrangement enables the sprocket 5 to rotate smoothly and effectively transmit power to the annealing kiln roller conveyor, ensuring the continuous and stable operation of the production line. At the same time, the structure is compact, easy and quick to install and maintain, and improves the overall reliability and efficiency of the equipment.

[0067] In a preferred embodiment, the sprocket 5 is detachably mounted on the sleeve 4 of the clamping assembly by means of screws 6 or other fasteners. This configuration allows the sprocket 5 to be easily and quickly disassembled and installed when maintenance or replacement is required, improving the maintainability and flexibility of the equipment. At the same time, the use of screws 6 or other fasteners also ensures the stability of the sprocket 5 during operation.

[0068] In a preferred embodiment, the clamping assembly further includes a flat key 7, a flat washer 9, and a spring washer 10. The flat key 7 is installed between the sleeve 4 and the sprocket 5 to ensure axial fixation between the clamping assembly and the annealing kiln roller conveyor. With the above configuration, the flat washer 9 and the spring washer 10 are sequentially fitted onto the bolt 6 and located on the side of the sprocket 5 away from the sleeve 4. The bolt 6 tightens and fixes the sprocket 5 and the sleeve 4, further enhancing the stability of the clamping assembly structure and ensuring smooth operation of the annealing kiln roller conveyor.

[0069] In the preferred embodiment, the flat washer 9 and the spring washer 10 are fitted onto the bolt 1 and installed between the sleeve 4 and the nut 8 to increase the locking force of the nut 8 and prevent loosening. The above configuration effectively improves the stability and safety of the connection structure. In addition, by adding anti-slip textures or coatings to the nut and contact surface, the friction is further enhanced to ensure a good fastening effect under various working conditions.

[0070] In a preferred embodiment, the operating component includes a crank handle 12 mounted on the clamping component bolt 1. The crank handle 12 is detachably installed on the shaft end of the clamping component and is used to manually drive the annealing kiln roller conveyor to rotate. This configuration not only allows the operator to quickly adjust the operating status of the annealing kiln roller conveyor according to actual needs, but also allows for easy disassembly of the crank handle 12 during maintenance, avoiding interference with the clamping component and effectively improving the operational flexibility and maintenance convenience of the annealing kiln.

[0071] In a preferred embodiment, the crank handle 12 is provided with a hole or groove for installing a pin 11, so that the crank handle 12 can be detachably installed onto the shaft end of the clamping component bolt 1 and fixed by the pin 11. The above configuration not only facilitates the user to quickly disassemble and assemble the crank handle 12 as needed, but also ensures that the fixing method of the pin 11 is stable and reliable, effectively preventing the crank handle 12 from loosening or falling off during use, thereby improving the stability of the overall structure and the convenience of operation.

[0072] In summary, the sprocket-assisted transmission device provided by this utility model aims to solve the key problems encountered in the operation of the annealing kiln roller conveyor in float glass factories. The innovative design of this device not only optimizes the operating efficiency of the annealing kiln roller conveyor, but also significantly improves the production quality of glass products.

[0073] Firstly, in response to the bending problem of the annealing kiln roller conveyor caused by temperature difference during use, this utility model provides a fast and effective straightening solution. By installing the device on the end of the annealing kiln roller conveyor shaft and using the crank handle 12 and pin 11 to achieve rapid rotation, the bent roller conveyor can be straightened quickly. This instant straightening function not only improves production efficiency, but also effectively reduces glass plate quality problems caused by roller conveyor bending, such as plate cracking, thereby reducing production losses.

[0074] Secondly, this device also solves the limitation that the annealing kiln roller conveyor cannot maintain the same speed when it malfunctions or is under maintenance. By using sprocket 5 and chain to connect multiple transition rollers in series, this invention realizes that when one or more roller conveyors stop due to a malfunction, the normally operating roller conveyor can drive the stopped roller conveyor to continue rotating. This design ensures that all roller conveyors can maintain the same speed, thereby avoiding serious process accidents such as scratches on the lower surface of the glass and breakage of the plate caused by the roller conveyor stopping, and further improving the continuity and safety of production.

[0075] In addition, this utility model has the advantages of convenient operation, easy disassembly and assembly, and small space occupation. The device can be operated online without stopping production, and the roller conveyor can be straightened and the transmission adjusted without stopping production, thereby greatly reducing the impact on the production process. At the same time, the disassembly and assembly process of the device is also very simple and quick, which is convenient for staff to carry out daily maintenance and repair.

[0076] It is worth mentioning that the unique locking and transmission mechanism of this utility model is also a major highlight. By locking the nut 8 and the bolt 1 to press the expansion sleeve 3, the device and the roller conveyor are pressed together as one unit, which not only ensures the stability of the device, but also realizes online operation without stopping production. This design not only improves the service life of the device, but also further enhances the flexibility and efficiency of production.

[0077] This utility model provides a sprocket-assisted transmission device, which offers an efficient and flexible solution for float glass factories with its unique design concept and excellent performance. The device not only solves the key problems encountered in the operation of the annealing kiln roller conveyor, but also significantly improves the production quality and efficiency of glass products, and has broad application prospects and market value.
