Description

Technical Field

[0001] The present invention relates to the technical field of aluminum melting processing, and specifically refers to a feeding mechanism for an aluminum melting furnace. Background Art

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

[0003] In the above operation, when the loading height of the loader is basically the same as the height of the melting furnace port, the vibrating feeder can directly add the material. However, when there is a large difference between the loading height of the loader and the height of the melting furnace, in order to ensure the loading height of the loader (generally lower) and at the same time ensure that the discharge port of the vibrating feeder (generally higher) can enter the melting furnace port, this height difference cannot be achieved by the existing vibrating feeder with a fixed height, reducing the application range of the device. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above difficulties and provide a feeding mechanism that can adaptively adjust the height of the vibrating feeder as needed when melting aluminum in a melting furnace.

The scissor lift assembly includes a lifting seat located below the vibrating feeder. A first moving seat and a second moving seat are both slidably arranged on the inner sides of one end of the lifting seat and the base respectively. Hinge seats are arranged on the inner sides of the other ends of the lifting seat and the base. A first swing rod forming a scissor structure is hinged between the first moving seat, the second moving seat and the hinge seats;

[0007] A locking assembly is arranged on the base to lock the second moving seat. The locking assembly includes a connecting frame arranged between the two second moving seats. An inverted U-shaped frame is arranged on the connecting frame, and a pawl with a rebound function is swingably arranged within this U-shaped frame.

An adjusting member for controlling the sliding of the movable seat is provided on the fixed seat. The action of the switching assembly transmits or separates the rotational power between the swing arm I and the rotating shaft I.

[0011] As an improvement, the switching assembly includes a spline provided on the rotating shaft I. A spline sleeve adapted to it is slidably arranged on the spline. An adjusting cylinder is rotatably arranged on the spline sleeve. Teeth are provided on the end face of the spline sleeve corresponding to the swing arm I. A groove adapted to the teeth is provided on an extension portion of the swing arm I. An electric push rod I is provided between the spline sleeve and the U-shaped frame.

[0012] As an improvement, the adjusting member is an electric push rod II arranged at the end of the fixed seat, and the movable end of the electric push rod II is connected to the end face of the movable seat.

[0013] As an improvement, rotating shafts II rotatably connected to the base are provided on two track running wheels at the same end. The braking assembly includes positioning discs arranged at both ends of the rotating shaft II. Front braking discs and rear braking discs that move relatively or in opposite directions are provided at both ends of each positioning disc. Bearing seats are provided at both ends of the base close to the positioning discs. Support frames are provided at both ends of the bearing seats, and sliding rods are slidably arranged in the support frames;

[0014] The opposite ends of two sliding rods on one side are threadedly connected with a threaded cylinder, and the spiral directions at both ends are opposite. The opposite ends of the two sliding rods are respectively fixedly connected to the corresponding front braking discs.

The front braking disc slides and drives the rear braking disc to perform opposite sliding operations through a linkage assembly.

[0015] As an improvement, the linkage assembly includes swing rods III respectively hinged on the front brake disc and the rear brake disc. The other ends of the two swing rods III are jointly hinged on the moving seat III. Both ends of the ratchet plate are fixedly provided with transition frames that are slidably matched with the inner wall of the base. The left moving seat III is fixedly connected to the corresponding transition frame, and the left-right sliding of the transition frame drives the ratchet plate to slide left and right, thereby adjusting the gap between the ratchets and the ratchet claws on the ratchet plate. A guide rod slidably matched with the end of the base is fixedly provided on the right moving seat III.

[0016] As an improvement, the adjustment assembly includes a swing arm II arranged on the threaded cylinder. An electric cylinder is hinged on the bearing seat, and the other end of the electric cylinder is hinged on the swing arm II.

[0017] The beneficial effects of the present invention compared with the prior art are as follows:

[0018] The scissor lift assembly provided can adaptively adjust the height of the vibrating feeder when the loader is loading materials and when entering the furnace mouth for discharging materials, so as to meet the situation where the height difference between the loading height of the loader and the furnace mouth is large for feeding operations;

[0019] Under the action of the lift assembly composed of the scissor structure and the two synchronous oil cylinders, the stability of the vibrating feeder during the height adjustment process can be ensured;

[0037] The present invention will be further described in detail below with reference to the accompanying drawings.

[0038] Combined with the attached Figure 1 and the attached Figure 2 and the attached Figure 3 As shown, a feeding mechanism for an aluminum melting furnace includes a base 1. Rail walking wheels 111 are rotatably provided at the four corners of the base 1. A rail 113 for the movement of the rail walking wheels 111 is provided at the place leading to the furnace 10. A vibrating feeder 2 is provided on the base 1, and a discharge opening 211 is provided on the vibrating feeder 2. It further includes:

[0039] A scissor lift assembly 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 lift assembly 3 drives the vibrating feeder 2 to adjust its height. A locking assembly 4 is arranged on the base 1 to lock the scissor lift assembly 3, avoiding the phenomenon of the scissor lift assembly 3 falling when the vibrating feeder 2 moves. A braking assembly 7 is arranged on the base 1 to brake the base 1. When the braking assembly 7 brakes the base 1, it also drives the locking assembly 4 to be tightly locked. When the braking assembly 7 releases the brake on the base 1, the locking assembly 4 can perform an unlocking action.

[0040] With the above structure, when there is a large difference in the feeding height between the vibrating feeder 2 and the feeding height of the furnace opening, the loader can first feed the molten material into the vibrating feeder 2, and then adjust the height of the vibrating feeder 2 through the scissor lift assembly 3 so that the discharge port 211 on the vibrating feeder 2 is adapted to the height position of the furnace opening. 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 opening. Then, perform a braking operation on the base 1 through the braking assembly 7, and at the same time drive the locking assembly 4 to lock the scissor lift assembly 3. Finally, start the vibrating feeder 2 so that the furnace charge is added to the furnace 10 in a vibrating manner. During the operation of the vibrating feeder 2, the locking assembly 4 is used to prevent the scissor lift assembly 3 from falling, thus ensuring the stability of the vibrating feeder 2 during the operation process.

[0041] Combined with the attached Figure 3 , the attached Figure 4 and the attached Figure 5 As shown, the scissor lift assembly 3 includes a lift base 310 located below the vibrating feeder 2. A first moving seat 311 and a second moving seat 312 are slidably provided on the inner sides of one ends of the lift base 310 and the base 1 respectively. Mounting seats 314 are provided on the inner sides of the other ends of the lift base 310 and the base 1. Hinge seats 315 are provided at both ends of the two mounting seats 314. A first swing rod 313 forming a scissor structure is hinged between the first moving seat 311, the second moving seat 312 and the hinge seats 315.

[0042] A connecting seat one 316 is provided at both ends of a group of parallel first swing rods 313. Connecting seats two 317 are provided on both sides of the hinge between the other group of first swing rods 313. Oil cylinders 318 are hinged between the connecting seat one 316 and the connecting seat two 317 on the same side, and the actions of the oil cylinders 318 at both ends are set synchronously. A hydraulic system (not shown in the figure) for the oil cylinders 318 to expand and contract is provided on the base 1. A locking assembly 4 for locking the second moving seat 312 is provided on the base 1.

[0043] For the working principle of the scissor lift assembly 3, control the expansion and contraction of the oil cylinders 318 at both ends to drive the first moving seat 311 and the second moving seat 312 to slide right or left for adjustment. Under the scissor structure formed by the hinged first swing rods 313, drive the lift base 310 to perform lifting adjustment, and at the same time drive the vibrating feeder 2 to perform height adjustment.

[0044] Combined with the attached Figure 6 and the attached Figure 7As shown, the locking assembly 4 includes a connecting frame 411 disposed between two second moving seats 312. An inverted U-shaped frame 412 is provided on the connecting frame 411, and a pawl 413 with a spring-back function is swingably disposed within the U-shaped frame 412. A ratchet plate 414 that cooperates with the pawl 413 is slidably disposed within the base 1. The operation of the braking assembly 7 drives the sliding of the ratchet plate 414, thereby adjusting the gap between the ratchet teeth on the ratchet plate 414 and the pawl 413. An adjusting assembly 5 is provided on the base 1, and the pawl 413 and the ratchet plate 414 are separated by means of this adjusting assembly 5;

[0045] A switching assembly 6 for combining or separating the rotational power between the pawl 413 and the adjusting assembly 5 is provided therebetween.

[0046] The working principle of the locking assembly 4 is as follows: First, the rotational power between the adjusting assembly 5 and the pawl 413 is separated by means of the switching assembly 6. When the second moving seat 312 slides to the right, it drives the connecting frame 411 to slide to the right, and then drives the pawl 413 to slide to the right. At this time, the pawl 413 slides over the ratchet plate 414 in a swinging manner. After the sliding adjustment of the second moving seat 312 is completed, a certain ratchet tooth on the pawl 413 and the ratchet plate 414 are engaged. During the swinging process of the pawl 413, since the rotational power between the adjusting assembly 5 and the pawl 413 is in a separated state, it will not cause a linkage effect on the adjusting assembly 5. When the discharge port 211 on the vibrating feeder 2 moves to extend into the furnace opening, the braking assembly 7 is controlled to operate, driving the ratchet plate 414 to move to the right so that the ratchet teeth thereof are in close contact with the pawl 413, thereby performing a locking operation on the pawl 413. At the same time, the connecting frame 411 and the second moving seat 312 are locked, thus avoiding the sliding phenomenon of the second moving seat 312 when the vibrating feeder 2 operates, and ensuring the stability of the scissor lift assembly 3 during the feeding process.

[0047] Combined with the attached Figure 7 、attached Figure 8 、attached Figure 9As shown, a first rotating shaft 415 rotatably engaged with the U-shaped frame 412 penetrates through the pawl 413. Torsion springs 417 are wound around the first rotating shaft 415 between the two ends of the pawl 413 and the inner wall of the U-shaped frame 412. One end of each torsion spring 417 is fixedly abutted against the end face of the pawl 413, and the other end is fixedly abutted against the inner wall of the U-shaped frame 412. The adjusting assembly 5 includes a first swing arm 511 rotatably arranged at the end of the first rotating shaft 415. A second swing rod 512 is hinged to the first swing arm 511. A fixed seat 513 is provided on the base 1 corresponding to the second swing rod 512, and a movable seat 514 is slidably arranged on the fixed seat 513. The other end of the second swing rod 512 is hinged to the movable seat 514. An adjusting member for controlling the sliding of the movable seat 514 is provided on the fixed seat 513. The adjusting member is a second electric push rod 515 arranged at the end of the fixed seat 513. The movable end of the second electric push rod 515 is connected to the end face of the movable seat 514. The operation of the switching assembly 6 enables the transmission or separation of the rotational power between the first swing arm 511 and the first rotating shaft 415.

[0048] The working principle of the adjusting assembly 5 is as follows: First, the switching assembly 6 combines the rotational power of the first swing arm 511 and the first rotating shaft 415. Then, the second electric push rod 515 is controlled to contract, driving the second swing rod 512 to swing to the right, further driving the hinged first swing arm 511 to swing to the right, simultaneously driving the first rotating shaft 415 to rotate, and then driving the pawl 413 to swing upward, separating the pawl 413 from the teeth on the ratchet plate 414, so that the scissor lift assembly 3 can be adjusted downward.

[0049] Combined with the attached Figure 10 and the attached Figure 11 As shown, the switching assembly 6 includes a spline 611 formed on the first rotating shaft 415. A spline sleeve 612 adapted to the spline 611 is slidably arranged on the spline 611. An adjusting cylinder 613 is rotatably arranged on the spline sleeve 612. External threads are formed on the spline sleeve 612, and a slotted nut 618 for blocking the adjusting cylinder 613 is threadedly arranged on the external threads. A tooth 614 is formed on the end face of the spline sleeve 612 corresponding to the first swing arm 511. An extension 615 is provided on the first swing arm 511, and a slot 616 adapted to the tooth 614 is formed on the extension 615. An electric push rod 617 is arranged between the spline sleeve 612 and the U-shaped frame 412.

[0050] The working principle of the switching assembly 6 is as follows: The electric push rod 617 is controlled to extend, driving the adjusting cylinder 613 to move forward, simultaneously driving the spline sleeve 612 to move forward, enabling the tooth 614 and the slot 616 to be combined, and at the same time enabling the spline sleeve 612 and the first swing arm 511 to be combined. Under the action of the spline sleeve 612, the first swing arm 511 and the first rotating shaft 415 are combined.

[0051] Combined with the attached Figure 1, Attachment Figure 12 and Attachment Figure 13 As shown in Figure 12 and Figure 13 , on both of the two track running wheels 111 at the same end, there are second rotating shafts 112 rotatably connected to the base 1. A speed reducer connected to any one of the second rotating shafts 112 is provided on the base 1, and a motor (not shown in the figure) connected to the speed reducer is also provided on the base 1. The braking assembly 7 includes positioning discs 711 arranged at both ends of each second rotating shaft 112. At both ends of each positioning disc 711, a front braking disc 712 and a rear braking disc 713 that move relatively or in opposite directions are provided. At both ends of the base 1 near the positioning discs 711, bearing seats 714 are provided. At both ends of each bearing seat 714, support frames 715 are provided, and sliding rods 716 are slidably arranged within these support frames 715;

[0052] The opposite ends of the two sliding rods 716 on one side are threadedly connected with a threaded cylinder 717 and the spiral directions at both ends are opposite. The opposite ends of the two sliding rods 716 are respectively fixedly connected to the corresponding front braking discs 712. An adjustment assembly 9 for rotating the threaded cylinder 717 is provided on the bearing seat 714. The front braking disc 712 drives the rear braking disc 713 to perform opposite sliding operations through a linkage assembly 8.

[0053] The working principle of the braking assembly 7 is as follows: By controlling the rotation of the threaded cylinder 717 through the adjustment assembly 9, under the action of the positive and negative external threads at both ends, the two sliding rods 716 at both ends are driven to move in opposite directions, and then the front braking discs 712 connected thereto are driven to move in opposite directions, so that the front braking discs 712 closely abut against one side of the positioning disc 711. Finally, the rear braking discs 713 opposite thereto are driven by the linkage assembly 8 to move towards the positioning disc 711 and closely 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 second rotating shaft 112, the track running wheels 111 and the base 1.

[0054] Combined with Attachment Figure 13 and Attachment Figure 14 As shown in Figure 13 and Figure 14 , the linkage assembly 8 includes swing rods three 811 respectively hinged to the opposite end faces of the front braking disc 712 and the rear braking disc 713. The other ends of the two swing rods three 811 at the same positioning disc 711 are jointly hinged to a moving seat three 812. A connecting frame 814 sleeved at the joint of the swing rods three 811 is fixedly provided on the front braking disc 712. The end of the sliding rod 716 is fixedly connected to the connecting frame 814. At both ends of the ratchet plate 414, transition frames 416 slidably matched with the inner wall of the base 1 are fixedly provided. The moving seat three 812 on the left 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 teeth on the ratchet plate 414 and the ratchet pawl 413. A guide rod 813 slidably matched with the end of the base 1 is fixedly provided on the moving seat three 812 on the right.

[0055] The working principle of the linkage component 8 is as follows: when the current brake disc 712 slides back and forth, it drives the swing rod three 811 connected to it to swing back and forth, and then drives the moving seat three 812 to slide left and right for adjustment. The left and right sliding of the moving seat three 812 not only drives the swing rod three 811 on the other side to slide back and forth for adjustment, so that the rear brake disc 713 moves towards the end of the positioning disc 711 and tightly abuts, but also can drive the transition frame 416 to move left and right, so that there is a distance or tight abutment adjustment between the ratchet teeth on the ratchet plate 414 and the cooperation of the ratchet pawl 413. When there is a distance between the ratchet plate 414 and the ratchet pawl 413, it can control the ratchet pawl 413 to swing upward and separate from the ratchet plate 414, so that the scissor lift component 3 can be controlled to lower. When the ratchet plate 414 and the ratchet pawl 413 are tightly abutted, it can effectively position the ratchet pawl 413, so that the scissor lift component 3 can be locked.

[0056] Combined with the attached Figure 13 and the attached Figure 14 As shown, the adjustment component 9 includes a swing arm two 911 arranged on the threaded cylinder 717, and the swing arm two 911 and the threaded cylinder 717 are connected by a key connection. Locking nuts 913 are also threadedly arranged on the threaded cylinder 717 at both ends of the swing arm two 911. An electric cylinder 912 is hinged on the bearing seat 714, and the other end of the electric cylinder 912 is hinged on the swing arm two 911.

[0057] The working principle of the adjustment component 9 is to control the elongation of the electric cylinder 912, drive the swing arm two 911 to swing downward, and at the same time drive the threaded cylinder 717 to rotate for adjustment.

[0058] In the specific implementation of the present invention, when the molten material is loaded into the vibrating feeder 2 by a loader, first, the height of the vibrating feeder 2 is adjusted by the scissor lift component 3 so that the loading height of the vibrating feeder 2 is adapted to the loading height of the loader. After the loading is completed, the height of the vibrating feeder 2 is adjusted again so that the height of the discharge port 211 is adapted to the height of the furnace mouth. Then, the base 1 is controlled to move, and at the same time, the vibrating feeder 2 is driven to move and the discharge port 211 thereof extends into the furnace mouth. Then, the brake component 7 brakes the base 1, and at the same time, the locking component 4 performs an operation to effectively lock the scissor lift component 3. Finally, the vibrating feeder 2 is started to act, and the molten material inside it is vibrated and added into the furnace 10, thereby increasing the use range of the device.

[0059] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. In general, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
