[0002] The current aluminum strip billet casting-rolling mill includes a holding furnace, a forebay, a casting-rolling device, and a coiler. The outflow port of the holding furnace is correspondingly arranged with the inflow port of the forebay so that the molten aluminum in the holding furnace can smoothly flow into the forebay. The casting-rolling device includes a frame, a casting nozzle, and rolling rolls. The output port of the forebay is connected to the casting nozzle so that the molten aluminum in the forebay flows into the casting nozzle, completing the supply process of the casting-rolling raw materials.

[0003] Publication No. CN218395858U discloses an inclined casting-rolling mill forebay. The device is arranged in a combined manner, thus reducing the influence of the liquid level fluctuation during the liquid inlet of the liquid inlet tank on the liquid level of the liquid outlet tank. At the same time, a filter screen is arranged inside the liquid inlet tank. Under the action of the filter screen, the sediment and scale contained in the molten aluminum are filtered to avoid affecting the quality of the casting-rolling products. Moreover, the filter screen is arranged in an inclined manner inside the liquid inlet tank, so that the sediment and scale move to the bottom baffle of the filter screen for collection, avoiding clogging of the filter screen, thereby enabling the smooth progress of the casting-rolling work.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figure 1-7, the present utility model provides a technical solution: an automatic hydraulic supply device for a casting-rolling mill, including a liquid inlet tank 1, the top end of the liquid inlet tank 1 is snap-connected with an end cover 101, and an inlet pipe 102 is installed inside the top end of the end cover 101.

[0030] Working principle: Before using this automatic hydraulic supply device for a casting-rolling machine, it is necessary to first check the overall situation of the device to ensure that it can work normally. According to Figure 1 - Figure 7As shown in the figure, by starting the hydraulic rod 205 to drive the toothed plate 206 to move back and forth, the movement of the toothed plate 206 drives the rotation of the fixed tooth 204. The rotation of the fixed tooth 204 drives the rotation of the rotating rod 203, and the rotation of the rotating rod 203 drives the rotation of the turntable 207. Furthermore, the rotation of the turntable 207 drives the movable rod 208 to run in a semi-circular regular manner, and then pulls the push rod 201 to move up and down back and forth. The up and down movement of the push rod 201 drives the movement of the inclined plate 209. The movement of the inclined plate 209 drives the up and down movement of the insertion pin 210 to clean and unclog the filter screen 104, so that the effect is better than the inclined design for cleaning and unclogging in the prior art, greatly reducing the clogging probability of the filter screen 104, thereby improving the filtering efficiency of the molten aluminum, achieving a further increase in the supply speed of the molten aluminum, bringing practicality to the staff during use. The movement of the inclined plate 209 drives the sliding sleeve 213 to slide on the limiting rod 212, thus greatly improving the movement stability of the inclined plate 209. The slider 214 is engaged and slidably connected to the inner top of the end cover 101, so that the toothed plate 206 can slide more stably;

[0031] The staff engages the end cover 101 with the liquid inlet tank 1, then connects the push rod 201 with the movable rod 208. By pressing the sliding rod 302 to drive the push block 303 to squeeze the extrusion rod 305, at this time, the extrusion plate 306 drives the first telescopic spring 307 to stretch, and then the insertion block 308 is engaged and fixed with the liquid inlet tank 1, thus achieving the effect of quickly installing and disassembling the end cover 101, which is convenient for the subsequent staff to clean the impurities on the filter screen 104 and brings convenience to the staff during use. By pulling the operating rod 310 to drive the movement of the connecting plate 311, at this time, the telescopic rod 313 and the second telescopic spring 314 contract. By releasing the operating rod 310, and then through the reset property of the second telescopic spring 314, the clamping block 312 is engaged and fixed with the sliding rod 302, so that the adjusted sliding rod 302 can be fixed and limited, and the phenomenon that the clamping block 312 is not stably fixed due to the movement of the push block 303 can be avoided. The limiting block 315 is slidably connected with the limiting groove 316, so that the push block 303 can move more stably.
