Description

Technical Field

[0001] This utility model relates to the technical field of ESP take-up area exit feed rollers, and in particular to a novel exit feed roller structure. Background Technology

[0002] The operating conditions of the feed rolls at the exit of the ESP coiling area are extremely harsh: the ambient temperature of the roll table is 450℃≤T≤680℃; the maximum linear speed of the rolls reaches 13m / s; the rolls are cooled by a mandrel; and lubrication is achieved through oil-air lubrication. This area is shut down for maintenance every 10 days, with a stoppage of approximately 1 hour between castings, and continuous rolling at other times.

[0003] The original design of the export feed roller by the foreign party adopted a transmission structure with a closed gearbox and intermediate meshing gears. This structure revealed several drawbacks in actual use: First, due to its compact structure, the transmission gears were prone to damage under high-temperature, high-speed, and heavy-load conditions, causing roller stalling, equipment failure, and severely impacting production continuity; second, roller stalling easily caused scratches on the lower surface of the steel plate, affecting product quality and causing economic losses; third, the gearbox seal was prone to aging at high temperatures, frequently resulting in oil leaks, requiring a large amount of lubricating oil replenishment annually, which was both wasteful of resources and polluted the environment; finally, the gearbox structure was complex, making maintenance difficult, labor-intensive, and time-consuming.

[0004] Therefore, in order to improve production efficiency, reduce production costs, improve product quality, and reduce the workload of maintenance personnel, it is necessary to modify and optimize the structure of the existing outlet feed roller device. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned technical problems and provide a novel outlet feed roller structure.

[0006] To achieve the above technical objectives and meet the above technical requirements, the technical solution adopted by this utility model is: a novel outlet feed roller structure, including a housing, an active synchronous wheel and a driven synchronous wheel are provided on the inner side wall of the housing, the active synchronous wheel is fixedly connected to the shaft end of the active roller by a first key, the driven synchronous wheel is fixedly connected to the shaft end of the driven roller by a second key, and a synchronous belt is sleeved between the active synchronous wheel and the driven synchronous wheel.

[0007] Preferably, the elevation of the driven roller surface is lower than that of the driving roller surface.

[0008] Preferably, the height difference between the driven roller surface and the driving roller surface is 4-8 mm.

[0009] Preferably, the timing belt is a quick-cut timing belt.

[0010] Compared with the traditional structure, the beneficial effects of this utility model are: This invention eliminates the original intermediate meshing gear and complex gearbox, and adopts synchronous belt drive, which has a simple and compact structure, fundamentally avoiding the problems of gear meshing damage and oil leakage, and making the transmission more reliable.

[0011] By lowering the elevation of the driven roller, the driven roller is made to be in a "lightly supporting" state during transmission. Even if a stall occurs, the pressure and friction on the lower surface of the strip are greatly reduced. Combined with the design of the quick-cutting synchronous belt, it provides double protection for handling extreme situations and preventing strip scratches, effectively reducing the intensity and frequency of maintenance.

[0013] The present invention will be further described below.

[0014] See attached document Figure 1 A novel outlet feed roller structure mainly includes a housing 1, a drive roller 3, a driven roller 6, a drive synchronous pulley 2, a driven synchronous pulley 7, and a synchronous belt 8.

[0015] The active synchronous pulley 2 is circumferentially fixed to the shaft end of the active roller 3 via the first key 4, thereby transmitting power to the active roller 3; the driven synchronous pulley 7 is circumferentially fixed to the shaft end of the driven roller 6 via the second key 5; the synchronous belt 8 is tautly fitted onto the active synchronous pulley 2 and the driven synchronous pulley 7, forming a complete belt drive system.

[0016] The elevation of the driven roller 6 is set lower than that of the driving roller 3, forming a height difference H. After repeated testing, the optimal range of this height difference H is 4mm to 8mm, and in this embodiment, it is preferably 6mm. This design ensures that the weight and tension of the strip are mainly borne by the driving roller 3 during transmission, while the driven roller 6 only plays an auxiliary guiding and light supporting role, fundamentally reducing the risk of scratching the strip due to the driven roller 6 stalling.

[0017] The synchronous belt 8 is preferably a quick-cut synchronous belt. In extreme cases such as jamming of the driven roller 6, maintenance personnel can quickly cut the synchronous belt 8, so that the driven roller 6 and the driven synchronous pulley 7 become freely rotating passive rollers, thereby immediately relieving the driving friction on the strip steel and protecting the lower surface of the strip steel from damage.

[0018] In specific implementation, firstly, the active synchronous pulley 2 is fixedly installed on the drive side shaft end of the active roller 3 via the first key 4; at the same time, the driven synchronous pulley 7 is fixedly installed on the shaft end of the driven roller 6 via the second key 5; then, the above pre-assembled parts are installed into the housing 1; a measuring tool is used to verify and ensure that the roller surface elevation of the driven roller 6 is lower than that of the roller surface elevation of the active roller 3, forming the required height difference H (preferably 6mm); finally, the synchronous belt 8 is fitted onto the active synchronous pulley 2 and the driven synchronous pulley 7, and the tensioning mechanism is adjusted to obtain appropriate tension for the synchronous belt to ensure smooth and reliable transmission; after all assembly is completed, the rotating parts are manually rotated to check whether they are flexible and free from jamming. After confirming that there are no errors, a no-load test run can be carried out, and the running trajectory of the synchronous belt and the vibration of the equipment are further checked. Once normal, it can be put into production.

[0019] The above embodiments of this utility model are merely examples to clearly illustrate this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent technical solutions also fall within the scope of this utility model, and the patent protection scope of this utility model should be defined by each claim.
