Description

Technical Field

[0001] The invention relates to the technical field of aluminum melting processing, in particular to a feeding mechanism of an aluminum melting furnace. Background Art

[0002] Aluminum melting furnace plays a very important role in aluminum processing. It can melt and purify aluminum materials, and provide high-quality raw materials for subsequent aluminum material processing. When melting aluminum in a melting furnace, a vibrating feeder is needed to add the charge into the furnace. The traditional feeding mechanism is to directly fix the vibrating feeder on a mobile base. The feeding process is that the loader first loads the charge into the vibrating feeder, and then the vibrating feeder moves along the track until the discharge port enters the furnace port, and then the charge is vibrated and added into the furnace.

[0003] In the above operation, when the loading height of the loader is basically consistent with the height of the furnace mouth, the vibrating feeder can be directly added. However, when the loading height of the loader is greatly different from the height of the furnace, it is necessary to ensure that the loader can load the material at a height (generally lower), and to ensure that the discharge port of the vibrating feeder (generally higher) can enter the furnace mouth. This height difference cannot be achieved by using the existing fixed-height vibrating feeder, which reduces the scope of use of the device. Summary of the invention

DETAILED DESCRIPTION

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0030] Combined with Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, a feeding mechanism of an aluminum smelting furnace includes a base 1, wherein track running wheels 111 are rotatably arranged at the four corners of the base 1, and rails 113 for the track running wheels 111 to move are arranged at the place leading to the melting furnace 10, a vibrating feeder 2 is arranged on the base 1, and a discharge port 211 is arranged on the vibrating feeder 2, and further includes: The scissor-type lifting component 3 is arranged between the top surface of the base 1 and the bottom surface of the vibrating feeder 2. The movement of the scissor-type lifting component 3 drives the vibrating feeder 2 to adjust its height. The locking component 4 is arranged on the base 1 and locks the scissor-type lifting component 3 to avoid the falling phenomenon of the scissor-type lifting component 3 when the vibrating feeder 2 is in motion. The braking component 7 is arranged on the base 1 and brakes the base 1. When the braking component 7 brakes the base 1, it also drives the locking component 4 to be tightly locked. When the braking component 7 releases the brake on the base 1, the locking component 4 can be unlocked.

[0031] Through the above structure, when the feeding height of the vibrating feeder 2 is greatly different from the feeding height of the furnace mouth, the loader can first put the molten material into the vibrating feeder 2, and then adjust the height of the vibrating feeder 2 through the scissor-type lifting component 3, so that the discharge port 211 on the vibrating feeder 2 is adapted to the height position of the furnace mouth, and then control the base 1 to move, and at the same time drive the vibrating feeder 2 to move, so that the discharge port 211 extends into the furnace mouth, and then brake the base 1 through the brake component 7, and drive the locking component 4 to lock the scissor-type lifting component 3, and finally start the vibrating feeder 2, so that the furnace charge is vibrated and added into the furnace 10. During the operation of the vibrating feeder 2, the locking component 4 prevents the scissor-type lifting component 3 from falling, thereby ensuring the stability of the vibrating feeder 2 during operation.

[0032] Combined with Figure 3 , Attachment Figure 4 and attached Figure 5 As shown, the scissor-type lifting assembly 3 includes a lifting seat 310 located below the vibrating feeder 2, and a moving seat 1 311 and a moving seat 2 312 are slidably provided on the inner sides of one end of the lifting seat 310 and the base 1, and a mounting seat 314 is provided on the inner sides of the other ends of the lifting seat 310 and the base 1, and both ends of the two mounting seats 314 are provided with hinged seats 315, and a swing rod 1 313 is hingedly connected between the moving seat 1 311, the moving seat 2 312 and the hinged seat 315 to form a scissor-type structure; A parallel set of rocker arms 1 313 are provided with connecting seats 1 316 at both ends, and another set of rocker arms 1 313 are provided with connecting seats 2 317 on both sides of the hinge. Cylinders 318 are hinged between connecting seats 1 316 and 2 317 on the same side, and the movements of the cylinders 318 at both ends are synchronously set. A hydraulic system (not shown in the figure) for extending and retracting the cylinders 318 is provided on the base 1, and a locking assembly 4 for locking the movable seat 2 312 is provided on the base 1.

[0033] The working principle of the scissor-type lifting assembly 3 is to control the extension and retraction of the oil cylinders 318 at both ends, drive the moving seat 1 311 and the moving seat 2 312 to slide rightward or leftward, and drive the lifting seat 310 to be raised and lowered under the scissor-type structure composed of the hinged rocker arm 1 313, and at the same time drive the vibrating feeder 2 to be height adjusted.

[0034] Combined with Figure 6 and attached Figure 7 As shown, the locking assembly 4 includes a connecting frame 411 arranged between two movable seats 312, an inverted U-shaped frame 412 is provided on the connecting frame 411, and a ratchet 413 with a rebound function is swingably provided in the U-shaped frame 412, a ratchet plate 414 used in conjunction with the ratchet 413 is slidably provided in the base 1, and the action of the brake assembly 7 drives the ratchet plate 414 to slide, thereby adjusting the gap size between the ratchet on the ratchet plate 414 and the ratchet 413, and an adjusting assembly 5 is provided on the base 1, and the ratchet 413 and the ratchet plate 414 are separated by the adjusting assembly 5; A switching assembly 6 is provided between the ratchet 413 and the adjusting assembly 5 to connect or separate the rotational forces of the two.

[0035] The working principle of the locking assembly 4 is that the switching assembly 6 is used to separate the rotational power between the adjusting assembly 5 and the pawl 413. When the movable seat 312 slides to the right, the connecting frame 411 is driven to slide to the right, and then the pawl 413 is driven to slide to the right. At this time, the pawl 413 slides on the ratchet plate 414 in a swinging manner. When the sliding adjustment of the movable seat 312 is completed, the pawl 413 is matched with a ratchet on the ratchet plate 414. During the swinging process of the pawl 413, due to the rotation between the adjusting assembly 5 and the pawl 413, The dynamic force is in a separated state, so it will not cause linkage influence on the adjustment component 5. When the discharge port 211 on the vibrating feeder 2 moves to extend into the furnace port, the brake component 7 is controlled to act, driving the ratchet plate 414 to move to the right so that its ratchet and pawl 413 are tightly abutted, thereby locking the pawl 413 and locking the connecting frame 411 and the movable seat 2 312 at the same time, thereby avoiding the sliding of the movable seat 2 312 when the vibrating feeder 2 is in action, and ensuring the stability of the scissor-type lifting component 3 during the feeding process.

[0037] The working principle of the adjustment component 5 is to first combine the rotational power of the swing arm 1 511 and the rotating shaft 1 415 through the switching component 6, and then control the electric push rod 2 515 to contract, drive the swing rod 2 512 to swing to the right, and then drive the hinged swing arm 1 511 to swing to the right, and at the same time drive the rotating shaft 1 415 to rotate, and then drive the pawl 413 to swing upward, so that the pawl 413 is separated from the ratchet on the ratchet plate 414, so that the scissor-type lifting component 3 can be adjusted downward.

[0038] Combined with Fig.10 and attached Fig.11 As shown, the switching assembly 6 includes a spline 611 provided on a rotating shaft 415, a spline sleeve 612 adapted thereto being slidably provided on the spline 611, an adjusting cylinder 613 being rotatably provided on the spline sleeve 612, an external thread being provided on the spline sleeve 612, and a slotted nut 618 for blocking the adjusting cylinder 613 being threadedly provided on the external thread, a latching tooth 614 being provided on the end face of the spline sleeve 612 corresponding to the swing arm 511, an extension portion 615 being provided on the swing arm 511, and a latching groove 616 adapted to the latching tooth 614 being provided on the extension portion 615, and an electric push rod 617 being provided between the spline sleeve 612 and the U-shaped frame 412.

Under the action of the spline sleeve 612, the swing arm 511 and the rotating shaft 415 are combined.

An adjustment component 9 for rotating the threaded tube 717 is provided on the bearing seat 714. The front brake disc 712 slides through the linkage component 8 to drive the rear brake disc 713 to perform an opposite sliding operation.

[0041] The working principle of the brake assembly 7 is to control the threaded cylinder 717 to rotate by adjusting the assembly 9, and under the action of the positive and negative external threads at both ends, drive the slide rods 716 at both ends to move away from each other, and then drive the front brake disc 712 connected thereto to move away from each other, so that the front brake disc 712 is tightly abutted against one side of the positioning disc 711, and finally drive the rear brake disc 713 opposite thereto to move in the direction of the positioning disc 711 through the linkage assembly 8 and tightly abut against the other side of the positioning disc 711, thereby effectively braking the positioning disc 711, and at the same time effectively braking the rotating shaft 2 112, the track walking wheel 111 and the base 1.

[0042] Combined with Fig.13 and attached Fig.14As shown, the linkage assembly 8 includes a rocker arm three 811 respectively hinged on the opposite end surfaces of the front brake disc 712 and the rear brake disc 713, the other ends of the two rocker arms three 811 at the same positioning disc 711 are hinged together on the moving seat three 812, and the front brake disc 712 is fixedly provided with a connecting frame 814 that is sleeved on the connection between the rocker arm three 811, and the end of the slide rod 716 is fixedly connected to the connecting frame 814, and both ends of the ratchet plate 414 are fixedly provided with a transition frame 416 that slides with the inner wall of the base 1, the moving seat three 812 on the left side is fixedly connected to the corresponding transition frame 416, and the left and right sliding of the transition frame 416 drives the ratchet plate 414 to slide left and right, thereby adjusting the gap size between the ratchet and the pawl 413 on the ratchet plate 414, and the moving seat three 812 on the right side is fixedly provided with a guide rod 813 that slides with the end of the base 1.

[0043] The working principle of the linkage assembly 8 is that when the front brake disc 712 slides back and forth, it drives the rocker bar three 811 connected thereto to swing back and forth, and then drives the moving seat three 812 to slide left and right. The left and right sliding of the moving seat three 812 not only drives the rocker bar three 811 on the other side to slide forward and backward, so that the rear brake disc 713 moves toward the end of the positioning disc 711 and abuts closely, but also drives the transition frame 416 to move left and right, so that there is a distance or a close abutment adjustment between the ratchet teeth and the pawl 413 on the ratchet plate 414.

[0045] The working principle of the adjustment component 9 is to control the extension of the electric cylinder 912, drive the second swing arm 911 to swing downward, and drive the threaded cylinder 717 to rotate and adjust.

[0046] In the specific implementation of the present invention, when the molten material is loaded into the vibrating feeder 2 by the loader, the height of the vibrating feeder 2 is first adjusted by the scissor-type lifting assembly 3 so that the loading height of the vibrating feeder 2 is adapted to the loading height of the loader.
