[0021] The method for using the aluminum rod melting device for aluminum profile production comprises the following steps:

[0022] S1: The user controls the furnace, feeder and nozzle rack in the device to start. The motor on the feeder drives the pressure roller to rotate, so that the pressure roller can drive the aluminum rod to slowly move into the feed pipe, and the high-temperature flame sprayed by the nozzle rack can melt the aluminum rod. The molten aluminum will flow into the furnace. At the same time, the device controls the lower servo motor and the upper servo motor to start;

[0023] S2: The output gear of the lower servo motor will drive the arc pressure cylinder to rotate through the gear ring. Since the connecting space between the arc pressure cylinder and the oil cylinder is filled with hydraulic oil, the rotating arc pressure cylinder will push the arc plug rod to rotate through the hydraulic oil, and the arc plug rod will drive the heat insulation ring to rotate. At this time, the heat insulation ring will drive the push plate on the bottom vertical rod to rotate, and the push plate will drive the molten aluminum in the furnace to flow, so that the molten aluminum can be evenly heated and maintain fluidity. When the molten aluminum level in the furnace continues to rise, the contact area between the molten aluminum and the push plate will increase synchronously. At this time, the resistance encountered by the push plate will increase synchronously. The push plate will synchronously apply resistance to the arc plug rod through the heat insulation ring, so that the pressure of the hydraulic oil in the arc pressure cylinder and the oil cylinder increases synchronously, so that the hydraulic oil can push the jacking plug rod to overcome the weight of the counterweight block and move. The counterweight block drives the moving ring to move synchronously, so that the moving ring can move upward to apply thrust to the trigger frame, and the trigger frame drives the first sleeve to move synchronously, so that the docking ring in the first sleeve approaches the docking hole on the inner core rod;

[0024] S3: The device controls the upper servo motor to start, and the upper servo motor will drive the inner core rod to rotate, and the inner core rod will drive the insulation plate, the support shell and the slag discharge pipe to rotate, and the support shell will drive the hollow shell and the collecting plate to rotate. The collecting plate is used to scrape impurities on the surface of the molten aluminum. When the molten aluminum level completely submerges the push plate and reaches the maximum resistance, the moving ring can just drive the docking ring to move to the docking position through the trigger frame and the first sleeve. At this time, the convex column on the docking ring can be embedded in the docking hole. At the same time, the moving ring will trigger the switch on the inner wall of the outer cover. The device controls the feeder to stop, and the inner core rod will drive the docking ring to rotate. At this time, the docking ring will drive the second sleeve to rotate through the first sleeve, so that the second sleeve can drive the threaded lifting ring to move, and the lifting ring will drive the control frame to move downward along the horizontal frame. At this time, the crossbar on the control frame will move along the through guide groove on the sliding plate to apply thrust, so that the sliding plate can push the horizontal frame to move horizontally through the spring. At this time, the inner rod and the outer rod at the bottom of the horizontal frame move synchronously. When the inner rod enters the rotation trajectory of the inner ring frame, the outer rod enters the rotation trajectory of the outer ring frame synchronously;

[0025] S4: The rotating heat insulation plate will drive the outer adjustment frame and the inner adjustment frame to rotate synchronously, and the outer adjustment frame will drive the outer ring frame to rotate, and the inner adjustment frame will drive the inner ring frame to rotate. At this time, the arc plate on the inner ring frame will first contact the inner rod. At this time, the inner ring frame will be pressed to move downward, and the inner ring frame will compress the inner reset spring. At the same time, the inner ring frame will drive the inner adjustment frame to move downward, so that the inner adjustment frame pushes the bottom rotating plate to rotate downward, and the rotating plate drives the hollow shell to rotate synchronously through the side block, and the hollow shell drives the collecting plate to rotate synchronously, so that the bottom end of the collecting plate rotates upward and leaves the surface of the aluminum liquid. At this time, the collecting plate The impurities collected on the upper part will move into the groove on the collecting plate, and then the arc plate on the outer ring frame will contact the outer rod, and the outer ring frame will also move downward, and the outer ring frame drives the outer adjustment frame to rotate downward, and the outer adjustment frame drives the force rod to rotate downward through the ring set, and the force rod will drive the hollow shell to rotate vertically. At this time, the hollow shell will drive the end of the collecting plate to tilt up, and the slag discharge port in the hollow shell is connected with the upper port of the slag discharge pipe, so that the impurities in the groove of the collecting plate will fall into the hollow shell, and the impurities in the hollow shell will be discharged through the slag discharge pipe; the impurities in the aluminum water are reduced by the repeated collection movement of the collecting plate;

[0026] S5: When the molten aluminum needs to be poured out for aluminum profile production and processing, the sealing electric cylinder is started so that the sealing block at the end of the sealing electric cylinder no longer blocks the discharge port of the furnace, and the molten aluminum can flow out of the furnace.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: the aluminum rod smelting device and the use method for aluminum profile production can automatically start the impurity collection mechanism on the surface of the aluminum liquid in the melting furnace through the resistance of the aluminum liquid to the push plate, thereby effectively reducing the impurity content in the aluminum liquid poured out by the device, and ensuring the quality of the aluminum profile products subsequently manufactured. The specific contents are as follows:

[0028] 1. The end of the arc plug rod is fixedly connected to a bracket of an insulation ring, and the bottom of the insulation ring is fixedly connected to a symmetrically distributed push plate, and the end of the arc pressure cylinder away from the arc plug rod is fixedly connected to the oil cylinder, and the lower part of the inner wall of the oil cylinder is fitted with a plug head of the jacking plug rod, and the rod body of the jacking plug rod slides through the top of the oil cylinder, and the center of the bottom surface of the counterweight block is fixedly connected to the rod body end of the jacking plug rod, and the top of the counterweight block is fixedly installed on the moving ring, and the convex ring on the top side wall of the first sleeve is rotatably embedded On the trigger frame, when the amount of molten aluminum in the furnace reaches the set value, the molten aluminum just covers the push plate. At this time, the push plate is subject to the greatest resistance. At this time, the resistance exerted by the push plate on the insulation ring and the arc plug rod will reach the maximum value simultaneously. During this process, the hydraulic oil pressure in the arc pressure cylinder and the cylinder barrel will increase synchronously. At this time, the lifting plug rod can push the counterweight block and the moving ring to move, so that the moving ring can push the trigger frame to move, so that the trigger frame can drive the transmission mechanism to operate, thereby realizing the subsequent impurity removal operation;

[0029] 2. An inclined rotating plate is fixedly connected to the outer wall of the side block, and the rotating plate is rotatably fitted in an arc groove opened on the side wall of the supporting shell, and the end of the rotating plate away from the side block is fitted and inserted between the horizontal axes at the lower end of the inner adjusting frame, and a force-bearing rod is fixedly connected to the outer wall of the hollow shell away from the collecting plate, and the axis of the force-bearing rod and the axis of the rotating plate are perpendicular to each other, and the axes of the force-bearing rod and the rotating plate both pass through the spherical center of the hollow shell, and the force-bearing rod fits through the slide groove on the outer wall of the supporting shell, and a slag discharge port is opened on the side of the outer wall of the hollow shell close to the force-bearing rod, and the slag discharge port is arranged above the upper port of the slag discharge pipe. When the rotating plate drives the hollow shell to rotate through the side block, the collecting plate connected at the feed port of the hollow shell will rotate upward synchronously, so that the collected aluminum water impurities can enter the groove of the collecting plate, and then the force-bearing rod will drive the hollow shell to rotate, so that the collecting plate will tilt up, and at this time, the impurities in the groove of the collecting plate can be discharged through the hollow shell and the slag discharge pipe.

[0053] The method for using the aluminum rod melting device for aluminum profile production comprises the following steps:

[0054] S1: The user controls the furnace 1, the feeder 3 and the nozzle rack 4 in the device to start.

[0055] S2: The output gear of the lower servo motor 12 will drive the arc pressure cylinder 10 to rotate through the gear ring 11. Since the connecting space between the arc pressure cylinder 10 and the oil cylinder 13 is filled with hydraulic oil, the rotating arc pressure cylinder 10 will push the arc plug rod 9 to rotate through the hydraulic oil, and the arc plug rod 9 will drive the insulation ring 7 to rotate. At this time, the insulation ring 7 will drive the push plate 5 on the bottom vertical rod to rotate. The push plate 5 will drive the aluminum liquid in the furnace 1 to flow, so that the aluminum liquid can be evenly heated and maintain fluidity. When the aluminum liquid level in the furnace 1 continues to rise, the contact area between the aluminum liquid and the push plate 5 will increase synchronously. At this time, the resistance of the push plate 5 will be synchronously increased, and the push plate 5 will synchronously apply resistance to the arc plug rod 9 through the heat insulation ring 7, so that the pressure of the hydraulic oil in the arc pressure cylinder 10 and the oil cylinder 13 will be synchronously increased, so that the hydraulic oil can push the jacking plug rod 14 to overcome the weight of the counterweight block 15 to move, and the counterweight block 15 drives the moving ring 16 to move synchronously, so that the moving ring 16 can move upward to apply thrust to the trigger frame 17, and the trigger frame 17 drives the first sleeve 1801 to move synchronously, so that the docking ring 1802 in the first sleeve 1801 approaches the docking hole 21 on the inner core rod 19;
