Description

Technical Field

[0001] This utility model relates to the field of recycled aluminum processing and production technology, specifically a continuous feeding device for recycled aluminum raw materials. Background Technology

[0002] Aluminum is a recyclable resource. Currently, recycled aluminum accounts for more than one-third of the world's annual primary aluminum production. Recycled aluminum is aluminum alloy or aluminum metal obtained by remelting and refining scrap aluminum and scrap aluminum alloy materials or aluminum-containing waste.

[0003] The existing method of adding raw materials to recycled aluminum furnaces is generally to use a loader to add the raw materials into the furnace. The raw materials that do not enter the furnace are supported by a support platform, and then modified forklifts and other machinery are used to push the raw materials on the support platform into the furnace. This method requires a lot of manpower and material resources, increasing production costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a continuous feeding device for recycled aluminum raw materials. By using a hydraulic push rod to rotate the feeding platform, the recycled aluminum raw materials on the feeding platform can be conveniently fed into the furnace, reducing manual labor and the use of mechanical equipment, and saving production costs.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a continuous feeding device for recycled aluminum raw materials, including a feeding platform, the outer sides of the feeding end of the feeding platform are rotatably connected to a bracket via a rotating shaft, a hydraulic push rod is installed between the bottom of the feeding platform and the bracket to push the feeding platform to rotate, a push plate is slidably connected to the inner side of the feeding platform, and a drive structure is provided at both ends of the push plate to reduce the sliding friction of the push plate; under normal feeding conditions without tilting, the height of the bottom plate of the feeding end of the feeding platform is greater than the height of the bottom plate of the feeding platform located at the bottom of the push plate starting end.

[0007] Furthermore, the drive structure includes a fixed shaft, rollers, and a guide box that guides the rollers to rotate. The rollers are rotatably connected to the outside of the fixed shaft and roll along the guide strip inside the guide box. The guide box is fixedly connected to the outer wall of the loading platform.

[0008] Furthermore, an isolation plate is connected to the outside of the fixed shaft via a bearing. The isolation plate is embedded inside the loading platform and is slidably connected inside the loading platform. The outer wall of the isolation plate and the inner wall of the side plate of the loading platform are on the same plane.

[0009] Furthermore, buffers are installed on the two side walls of the guide box in the direction of roller movement, and the anti-collision caps of the buffers that contact the rollers have grooves that match the shape of the rollers.

[0010] Furthermore, a support belt is fixedly connected to the side of the push plate facing the feeding end of the feeding platform. The support belt is attached to the outer surface of the bottom plate of the feeding platform, and the moving end of the support belt extends into the interlayer of the bottom plate of the feeding platform and is fixedly connected to several tension springs.

[0011] Furthermore, the feeding end of the lower base plate of the feeding platform is rotatably connected to a guide roller for reducing the friction of the support belt, and the top of the guide roller is on the same straight line as the upper surface of the lower base plate of the feeding platform.

[0012] The beneficial effects of this utility model are as follows:

[0013] By installing hydraulic push rods on the bracket, the hydraulic push rods push the feeding platform to flip, allowing recycled aluminum raw materials to be fed into the furnace under gravity. The push plate, which can move back and forth under gravity and is installed on the inner side of the feeding platform, can flip upward at the rear of the feeding platform and move to the feeding end of the feeding platform, so that the raw materials on the feeding platform can be completely fed into the furnace, preventing the raw materials from remaining on the feeding platform. Thus, feeding can be completed without the aid of forklifts or other mechanical equipment, saving production costs. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] See Figures 1-7 A continuous feeding device for recycled aluminum raw materials includes a feeding platform 1. The outer sides of the feeding end of the feeding platform 1 are rotatably connected to the bracket 2 via a rotating shaft. A hydraulic push rod 3 is installed between the bottom of the feeding platform 1 and the bracket 2 to push the feeding platform 1 to rotate. A push plate 4 is slidably connected to the inner side of the feeding platform 1. Both ends of the push plate 4 are provided with a drive structure for reducing the sliding friction of the push plate 4.

[0024] Under normal conditions where the feeding platform 1 is not flipped, the height of the bottom plate at the feeding end of the feeding platform 1 is greater than the height of the bottom plate at the bottom of the starting end of the push plate 4.

[0025] In this scheme: by using the hydraulic push rod 3 on the bracket 2 to push the loading platform 1 to flip, the loading platform 1 is tilted towards the furnace feed port, which makes it easier for the raw materials falling on the loading platform 1 to be fed into the furnace under the action of gravity. At the same time as the loading platform 1 flips, the push plate 4 can also move to the feeding end of the loading platform 1 under the action of gravity, thereby pushing all the raw materials on the loading platform 1 into the furnace, reducing the amount of raw materials remaining on the loading platform 1, so that feeding can be completed without the aid of forklifts or other mechanical equipment, saving production costs;

[0026] When the feeding platform 1 is placed flat on the bracket 2, since the feeding platform 1 is not level with the ground and the end of the feeding platform 1 away from the furnace feed inlet is relatively low, the push plate 4 at the feeding end of the feeding platform 1 can move backward and reset under the action of gravity, which facilitates the feeding platform 1 and the push plate 4 to feed materials back and forth, and improves the practicality of the feeding platform 1.

[0027] The drive structure includes a fixed shaft 5, a roller 6, and a guide box 7 that guides the roller 6 to rotate. The roller 6 is rotatably connected to the outside of the fixed shaft 5 and rolls along the guide strip 8 inside the guide box 7. The guide box 7 is fixedly connected to the outer wall of the loading platform 1.

[0028] In this embodiment: the fixed shaft 5 can connect the push plate 4 and the roller 6, so that when the roller 6 rotates in the guide box 7, it can drive the push plate 4 to move, reducing the sliding friction and resistance of the push plate 4. The guide box 7 can support the roller 6, and the guide bar 8 in the guide box 7 can make the roller 6 roll back and forth in a straight line, improving the stability of the push plate 4 when sliding in the loading platform 1.

[0029] An isolation plate 9 is connected to the outside of the fixed shaft 5 via a bearing. The isolation plate 9 is embedded in the inside of the loading platform 1 and is slidably connected to the inside of the loading platform 1. The outer wall of the isolation plate 9 and the inner wall of the side plate of the loading platform 1 are on the same plane.

[0030] In this embodiment, the isolation plate 9 can seal the groove of the fixed shaft 5 on the side plate of the feeding platform 1, preventing the raw material from getting stuck in the groove of the fixed shaft 5 and affecting the normal sliding of the push plate 4, thereby improving the stability of the push plate 4 sliding inside the feeding platform 1.

[0031] A buffer 10 is installed on the two side walls of the guide box 7 in the direction of movement of the roller 6. The anti-collision cap of the buffer 10 in contact with the roller 6 has a groove that matches the shape of the roller 6.

[0032] In this embodiment: by setting a buffer 10 on the guide box 7, when the roller 6 drives the push plate 4 from one end of the loading platform 1 to the other end, the roller 6 can hit the buffer 10. The buffer 10 buffers the impact force between the roller 6 and the push plate 4, thereby reducing the vibration generated when the roller 6 and the push plate 4 move in the guide box 7 and the loading platform 1, and improving the stability of the roller 6 and the push plate 4 on the loading platform 1.

[0033] A support belt 11 is fixedly connected to the side of the push plate 4 facing the feeding end of the feeding platform 1. The support belt 11 is attached to the outer surface of the bottom plate of the feeding platform 1. The moving end of the support belt 11 extends into the interlayer of the bottom plate of the feeding platform 1 and is fixedly connected to several tension springs 12.

[0034] In this embodiment: the support belt 11 can be laid flat on the surface of the lower bottom plate of the feeding platform 1, thereby supporting the raw materials. During the process of the push plate 4 moving to the feeding end of the feeding platform 1, the support belt 11 can move with the push plate 4 under the tension of the tension spring 12, so that the raw materials on the support belt 11 can be stably fed into the furnace, preventing raw material debris from remaining inside the feeding platform 1 or getting stuck between the bottom of the push plate 4 and the lower bottom plate of the feeding platform 1, and improving the stability of the push plate 4 when it moves. It should be noted that the support belt 11 can be an enhanced high temperature resistant and wear-resistant nylon conveyor belt. After the feeding platform 1 is completed and flipped over again above the bracket 2, when the push plate 4 moves to the starting end of the feeding platform 1 to reset, the push plate 4 can pull the support belt 11 to move and stretch the tension spring 12 to reset under the action of gravity.

[0035] The feeding end of the lower base plate of the feeding platform 1 is rotatably connected to a guide roller 13 for reducing the friction of the support belt 11. The top of the guide roller 13 is on the same straight line as the upper surface of the lower base plate of the feeding platform 1.

[0036] In this embodiment: when the support belt 11 slides inside the loading platform 1, the guide roller 13 can rotate with the support belt 11, thereby reducing the friction of the support belt 11 sliding on the bottom plate of the loading platform 1, thereby reducing the sliding resistance of the support belt 11 and improving the stability of the support belt 11 sliding on the loading platform 1.

[0037] During operation, the loader feeds raw materials into the furnace. Materials not fed into the furnace fall onto the support belt 11 in the feeding platform 1. When the hydraulic jack 3 is activated, it pushes the feeding platform 1 to flip towards the furnace's feed inlet, causing some raw materials to fall into the furnace under gravity. As the feeding platform 1 flips, the height of the roller 6 and the push plate 4 increases. The roller 6 rolls along the guide bar 8 under gravity, thereby driving the push plate 4 to move towards the feeding end of the feeding platform 1. As the push plate 4 moves, the tension spring 12 pulls the support belt 11 to move into the interlayer of the feeding platform 1, thus feeding all the raw materials into the furnace. After the raw materials are fed, the hydraulic jack 3 drives the feeding platform 1 to flip and reset. When the feeding platform 1 is completely placed above the bracket 2, because the feeding platform 1 is not level with the ground and the end of the feeding platform 1 away from the furnace feed inlet is relatively low, the push plate 4 at the feeding end of the feeding platform 1 can move backward and reset under gravity.

[0038] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
