Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy ingot casting technology, specifically to a uniform feeding device for aluminum alloy ingot casting. Background Technology

[0002] Aluminum alloy ingots are metal ingots made primarily of aluminum, with the addition of other alloying elements, through processes such as smelting and casting. Aluminum alloy ingots can be classified into several series based on the composition and proportion of alloying elements, such as aluminum-silicon alloy ingots, aluminum-copper alloy ingots, and aluminum-magnesium alloy ingots. These alloy ingots possess characteristics such as low density, high strength, and corrosion resistance, and are widely used in aviation, aerospace, automotive, rail transportation, electronics, and construction industries. In the aluminum alloy ingot casting process, a uniform feeding device is a crucial auxiliary equipment. It helps to achieve uniform and continuous feeding of alloy materials, thereby ensuring casting quality and improving production efficiency.

[0003] During the casting of existing aluminum alloy ingots, the raw materials may clump together. Without effective anti-clogging measures, blockages can easily occur at the inlet, conveying channel, and outlet. Larger clumps of material can easily get stuck at the inlet, hindering the normal entry of materials and gradually accumulating to form a blockage. Once a blockage occurs, it affects the production progress and requires a lot of time and manpower for cleaning, increasing production costs. Therefore, a uniform feeding device for aluminum alloy ingot casting is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is: a uniform feeding device for aluminum alloy ingot casting, comprising:

[0005] A feeding hopper and a feeding pipe fixedly connected to the bottom of the feeding hopper, wherein a mounting frame is fixedly connected to the bottom of the feeding pipe;

[0006] An anti-blocking device, which penetrates the outer wall of the feed pipe and extends into the interior of the feed pipe, is used to prevent the feed pipe from becoming blocked.

[0007] A feeding device, which penetrates the outer wall of the feeding pipe and extends into the interior of the feeding pipe, is located below the anti-blocking device, and is used to feed the material in the feeding pipe at a uniform speed.

[0008] The anti-blocking device includes a bracket, a motor is fixedly connected to one end of the bracket away from the hopper, a first rotating rod is fixedly connected to the output end of the motor, a locking block is fixedly connected to the outer wall of the first rotating rod, a guide shaft is slidably connected to the outer wall of the locking block, a support rod is fixedly connected inside the guide shaft, a spring is sleeved on the outer wall of the support rod, and a stirring rod is fixedly connected to the outer wall of the guide shaft.

[0009] Preferably, the outer wall of the guide shaft is slidably connected to the circular hole on the outer wall of the feed tube, the inner wall of the guide shaft is slidably connected to the outer wall of the first rotating rod, and the end of the guide shaft away from the first rotating rod is set with an inclined surface and is adapted to be matched with the inclined groove on the inner wall of the feed tube.

[0010] Preferably, the end of the spring away from the locking block is fixedly connected to the inner wall of the guide shaft, the end of the spring near the locking block is fixedly connected to the end of the first rotating rod near the locking block, and the end of the bracket away from the motor is fixedly connected to the outer wall of the feed tube. The two inclined surfaces press together, causing the guide shaft to slide in the direction of the first rotating rod. The spring inside the guide shaft is compressed under the restriction of the support rod. When the inclined surface at the end of the guide shaft is not pressed by the inclined groove, the guide shaft slides away from the motor under the elastic action of the spring.

[0011] Preferably, a second rotating rod is rotatably connected inside the feeding tube, a pulley is fixedly sleeved on the outer wall of the second rotating rod, an elliptical block is fixedly connected to the outer wall of the second rotating rod, a receiving block is fixedly connected to the inner wall of the feeding tube, a feeding block is sleeved on the inner wall of the receiving block, an extrusion rod is fixedly connected to the bottom of the feeding block, and a limiting rod is sleeved on the outer wall of the extrusion rod.

[0012] Preferably, two pulleys are fixedly fitted on the outer wall of the second rotating rod and the outer wall of the first rotating rod, respectively. The two pulleys are connected by a belt. When the first rotating rod rotates, the second rotating rod is driven to rotate through the pulleys.

[0013] Preferably, the top of the receiving block is inclined, the top of the feeding block is inclined, the outer wall of the feeding block is slidably connected to the inner wall of the receiving block, the elliptical block is elliptical, the end of the extrusion rod away from the feeding block is arc-shaped, the elliptical block is slidably connected to the extrusion rod, and the rotating elliptical block extrudes the bottom of the extrusion rod, causing the extrusion rod to drive the feeding block to slide upward on the inner wall of the limiting rod.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting an anti-blocking device, enables the motor to drive the first rotating rod to rotate, and the clamping block to drive the guide shaft to rotate. The stirring rod on the outer wall of the guide shaft stirs and disperses the material, effectively preventing the material from accumulating and blocking in the feeding pipe. In particular, it disperses raw materials that are lumpy, improving the smoothness of feeding. The end of the guide shaft away from the motor is set with an inclined surface, which is matched with the inclined groove on the inner wall of the feeding pipe. During the rotation of the guide shaft, the two inclined surfaces squeeze and make the guide shaft slide on the first rotating rod. At the same time, the spring is compressed and rebounded under the restriction of the support rod, so that the guide shaft drives the stirring rod to shake and stir back and forth continuously. This not only makes the material more evenly stirred and dispersed, but also further prevents material blockage and ensures that the feeding pipe always remains unobstructed.

[0016] 2. By setting up a feeding device, since the top of the receiving block and the feeding block are set at an angle, the material can be prevented from accumulating on top of them. At this time, the rotating elliptical block continuously squeezes the extrusion rod, which in turn continuously pushes the feeding block, thereby achieving uniform feeding of the material. This uniform feeding device can accurately control the feeding speed according to the actual production needs, avoiding production fluctuations caused by unstable feeding speed.

Example

[0026] Please see Figure 1 - Figure 7 This utility model provides a technical solution: a uniform feeding device for aluminum alloy ingot casting, comprising:

[0027] The feeding hopper 1 and the feeding pipe 2 fixedly connected to the bottom of the feeding hopper 1 are provided. The bottom of the feeding pipe 2 is fixedly connected to the mounting frame 3. The anti-blocking device 4 penetrates the outer wall of the feeding pipe 2 and extends into the interior of the feeding pipe 2.

The feeding device 5 penetrates the outer wall of the feeding pipe 2 and extends into the interior of the feeding pipe 2. The feeding device 5 is located below the anti-blocking device 4. The feeding device 5 is used to feed the material in the feeding pipe 2 at a uniform speed.

[0028] The anti-blocking device 4 includes a bracket 41. A motor 42 is fixedly connected to one end of the bracket 41 away from the hopper 1. A first rotating rod 43 is fixedly connected to the output end of the motor 42. A locking block 44 is fixedly connected to the outer wall of the first rotating rod 43. A guide shaft 45 is slidably connected to the outer wall of the locking block 44. A support rod 46 is fixedly connected inside the guide shaft 45. A spring 47 is sleeved on the outer wall of the support rod 46. A stirring rod 48 is fixedly connected to the outer wall of the guide shaft 45.

[0029] The outer wall of the guide shaft 45 is slidably connected to the round hole on the outer wall of the feed tube 2, and the inner wall of the guide shaft 45 is slidably connected to the outer wall of the first rotating rod 43. The end of the guide shaft 45 away from the first rotating rod 43 is set with an inclined surface and is adapted to the inclined groove on the inner wall of the feed tube 2. The end of the spring 47 away from the locking block 44 is fixedly connected to the inner wall of the guide shaft 45, and the end of the spring 47 near the locking block 44 is fixedly connected to the end of the first rotating rod 43 near the locking block 44. The end of the bracket 41 away from the motor 42 is fixedly connected to the outer wall of the feed tube 2.

[0030] The inside of the feeding pipe 2 is rotatably connected to a second rotating rod 55. A pulley 57 is fixedly sleeved on the outer wall of the second rotating rod 55. An elliptical block 56 is fixedly connected to the outer wall of the second rotating rod 55. A receiving block 51 is fixedly connected to the inner wall of the feeding pipe 2. A feeding block 52 is sleeved on the inner wall of the receiving block 51. An extrusion rod 53 is fixedly connected to the bottom of the feeding block 52. A limiting rod 54 is sleeved on the outer wall of the extrusion rod 53.

[0031] Two pulleys 57 are fixedly sleeved on the outer wall of the second rotating rod 55 and the outer wall of the first rotating rod 43, respectively. The two pulleys 57 are connected by a belt. The top of the receiving block 51 is set with an incline, the top of the feeding block 52 is set with an incline, the outer wall of the feeding block 52 is slidably connected to the inner wall of the receiving block 51, the elliptical block 56 is elliptical, and the end of the extrusion rod 53 away from the feeding block 52 is set with an arc surface. The elliptical block 56 is slidably connected to the extrusion rod 53.

[0032] Working principle:

[0033] In use, the mounting frame 3 of the device is bolted to the feed inlet of the aluminum alloy ingot casting equipment. When material needs to be fed, to prevent material from accumulating and clogging in the feed pipe 2, the motor 42 is started, causing the first rotating rod 43 fixedly connected to the output end of the motor 42 to start rotating. The locking block 44 fixedly connected to the outer wall of the first rotating rod 43 rotates accordingly, driving the guide shaft 45 slidably connected to its outer wall to rotate. The stirring rod 48 fixedly connected to the outer wall of the guide shaft 45 also starts to rotate, thus starting to stir the material. Since the end of the guide shaft 45 away from the motor 42 is set at an angle and is connected to the inclined groove on the inner wall of the feed pipe 2, the material can be stirred. With the touch setting, as the guide shaft 45 rotates, the two inclined surfaces press against each other, causing the guide shaft 45 to slide towards the first rotating rod 43. The spring 47 inside the guide shaft 45 is compressed under the restriction of the support rod 46. When the inclined surface at the end of the guide shaft 45 is no longer pressed by the inclined groove, the guide shaft 45 slides away from the motor 42 under the elastic action of the spring 47. Due to the continuous rotation of the first rotating rod 43, the inclined surface of the guide shaft 45 is continuously pressed against the inclined groove, and the spring 47 is continuously compressed, which can cause the guide shaft 45 to drive the stirring rod 48 to continuously shake and stir, so that the material can be stirred and dispersed more evenly.

[0034] When the first rotating rod 43 rotates, it drives the second rotating rod 55 to rotate via the pulley 57. The rotating second rotating rod 55 causes the elliptical block 56 fixedly sleeved on its outer wall to rotate as well. The rotating elliptical block 56 presses against the bottom of the extrusion rod 53, causing the extrusion rod 53 to drive the material feeding block 52 to slide upward on the inner wall of the limiting rod 54. This prevents the outer side of the material feeding block 52 from contacting the inner side of the receiving block 51. The material above the material feeding block 52 will fall through the gap between the material feeding block 52 and the receiving block 51 to the bottom of the receiving block 51, thus feeding the falling material into the aluminum alloy ingot casting equipment. As the elliptical block 56 continues to rotate, the extrusion rod 53 can make the material feeding block 52 continuously move up and down, thereby achieving uniform feeding of the material.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
