Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum-lithium alloy processing technology, specifically to a feeding device for producing aluminum-lithium alloys. Background Technology
[0002] Lithium is the lightest metallic element in the world. Adding lithium as an alloying element to metallic aluminum forms an aluminum-lithium alloy. Adding lithium can reduce the specific gravity of the alloy and increase its stiffness, while still maintaining high strength, good corrosion resistance and fatigue resistance, and suitable ductility. Because of these properties, this new alloy has attracted widespread attention from the aviation, aerospace and marine industries. It is precisely because of the many advantages of this alloy that it has attracted many scientists to study it, and the development of aluminum-lithium alloys has sprung up rapidly.
[0003] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. When the material particles are large, irregular in shape, or contain a lot of impurities, they are prone to accumulate at the feed inlet. For example, in the production of aluminum-lithium alloys, if the raw material is a blocky metal or contains some agglomerated powder, it will get stuck at the feed inlet, preventing the material from smoothly entering the device. This will interrupt the entire production process and reduce production efficiency. 2. In the production of aluminum-lithium alloys, the ratio of various raw materials has a crucial impact on the performance of the alloy. If the feed amount cannot be accurately controlled, it will lead to an imbalance in the raw material ratio. For example, the ratio of aluminum to lithium is one of the key factors that determines the strength, toughness, and other properties of aluminum-lithium alloys. If the amount of lithium fed is too much or too little, the performance of the alloy will not meet the expected standards, resulting in quality problems such as insufficient alloy strength and poor toughness. Utility Model Content
[0004] The purpose of this utility model is to provide a feeding device for producing aluminum-lithium alloys, to solve the problem mentioned in the background art where large-particle, irregularly shaped materials or materials containing many impurities tend to accumulate at the feed inlet, causing blockage of the feed opening. To achieve the above objective, this utility model provides the following technical solution: a feeding device for producing aluminum-lithium alloys, comprising a conveying shell, a connecting pipe welded to the top of the conveying shell, and a feed inlet welded to the top of the connecting pipe;
[0005] The housing of the third motor is mounted on one side of the conveyor housing by screws, and the auger conveyor shaft is mounted on the output shaft side of the third motor by screws.
[0006] The housing of the first motor is mounted on the front of the feed inlet by screws. The output shaft of the first motor is connected to the second gear. The first gear meshes with the second gear on one side. The rear of the first gear is rotatably connected to the second stirring shaft. The rear of the second gear is rotatably connected to the first stirring shaft. The housing of the second motor is mounted on one side of the feed inlet by screws. The feed limiting wheel is mounted on the rear output shaft of the second motor by screws.
[0007] A rotating plate is fitted inside the connecting pipe, and a weighing pressure sensor is installed inside the rotating plate by screws. A support plate is installed in front of the connecting pipe by screws, and a slide rail is installed above the support plate by screws. A rack is fitted inside the slide rail, and a third gear meshes above the rack. A rotating shaft is rotatably connected inside the third gear. A cylinder controller is installed above the support plate by screws, and a drive cylinder is installed above the support plate by screws. A push plate is installed on the output shaft in front of the drive cylinder by screws.
[0008] More preferably, the limiting wheel is configured to rotate via a second motor, and the outer structure of the blades of the limiting wheel is attached to the lower inner wall of the feed inlet.
[0009] More preferably, the second gear forms a rotating structure via the first motor, and the first gear forms a rotating structure via the second gear.
[0010] More preferably, the feed inlet has a first stirring shaft and a second stirring shaft horizontally distributed inside, and the first stirring shaft forms a rotating structure through a second gear, and the second stirring shaft forms a rotating structure through a first gear.
[0011] More preferably, the push plate forms a horizontal sliding structure through a drive cylinder, and the support plate is welded to the rack. The external structural dimensions of the rack are consistent with the internal structural dimensions of the slide rail. The third gear forms a rotating structure through the rack, and the rotating shaft is connected to the third gear. The rotating plate forms a rotating structure through the rotating shaft.
[0012] More preferably, the auger conveyor shaft is configured to rotate via a third motor.
[0013] More preferably, the weighing pressure sensor is connected to the cylinder controller via a cable, and the cylinder controller is connected to the drive cylinder via a cable.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] In this invention, a first stirring shaft and a second stirring shaft are horizontally distributed inside the feed inlet. Driven by a first motor, the two stirring shafts stir the added material. For materials with large particles, irregular shapes, or containing many impurities, the stirring shafts can break up the lumpy metal or agglomerated powder accumulated at the feed inlet, allowing it to pass smoothly through the feed inlet into subsequent stages, effectively preventing feed inlet blockage, ensuring the continuity of the production process, and improving production efficiency. At the same time, the limiting wheel forms a rotating structure through the second motor, and its blades are attached to the lower inner wall of the feed inlet. The limiting wheel can control the speed and amount of material entering the feed inlet. For large particles or materials with many impurities that are prone to clogging the feed inlet, the rotation speed of the limiting wheel can be adjusted to slowly and stably control the material to enter, avoiding a large amount of material rushing in at the same time and causing blockage. In addition, the blades of the limiting wheel are attached to the inner wall of the feed inlet, which can further prevent material from accumulating at the feed inlet and ensure that the material enters the device smoothly.
[0016] In this invention, the weighing pressure sensor and the cylinder controller are connected by a cable, and the cylinder controller and the drive cylinder are also connected by a cable. When the weighing pressure sensor detects that the material has reached a certain weight, it transmits a signal to the cylinder controller. The cylinder controller controls the drive cylinder to work. The front output shaft of the drive cylinder pushes the push plate, which pushes the rack to slide horizontally in the slide rail. The rack drives the third gear to rotate, and the rotating shaft inside the third gear drives the rotating plate to rotate, pouring the material into the conveyor shell. This automated control system can accurately adjust the feeding amount according to the weighing result, ensuring the accuracy and stability of the feeding amount and meeting the strict requirements of the production process for the raw material ratio.

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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1 to 6 This utility model provides a technical solution: a feeding device for producing aluminum-lithium alloy, including a conveying shell 1, a connecting pipe 3 welded to the top of the conveying shell 1, and a feeding port 2 welded to the top of the connecting pipe 3.
[0026] The housing of the third motor 101 is mounted on one side of the conveyor housing 1 by screws, and the screw conveyor shaft 102 is mounted on the output shaft side of the third motor 101 by screws.
[0027] The housing of the first motor 203 is screwed onto the front of the feed inlet 2. The output shaft of the first motor 203 is connected to the second gear 202. The first gear 204 meshes with one side of the second gear 202. The second stirring shaft 205 is rotatably connected to the rear of the first gear 204. The first stirring shaft 201 is rotatably connected to the rear of the second gear 202. The housing of the second motor 207 is screwed onto one side of the feed inlet 2. The feed limiting wheel 206 is screwed onto the output shaft of the second motor 207.
[0028] A rotating plate 302 is fitted inside the connecting pipe 3. A weighing pressure sensor 301 is installed inside the rotating plate 302 by screws. A support plate 306 is installed in front of the connecting pipe 3 by screws. A slide rail 304 is installed above the support plate 306 by screws. A rack 310 is fitted inside the slide rail 304. A third gear 303 meshes above the rack 310. A rotating shaft 307 is rotatably connected inside the third gear 303. A cylinder controller 309 is installed above the support plate 306 by screws. A drive cylinder 308 is installed above the support plate 306 by screws. A push plate 305 is installed on the output shaft in front of the drive cylinder 308 by screws.
[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 5 As shown, the limiting wheel 206 forms a rotating structure through the second motor 207, and the outer structure of the blades of the limiting wheel 206 is attached to the lower inner wall of the feed inlet 2. The limiting wheel 206 precisely controls the material flow rate to ensure the stability of feeding. For example, when producing aluminum-lithium alloy, the rotation speed of the limiting wheel 206 can be flexibly adjusted according to different production needs, thereby controlling the amount of material entering and improving the accuracy and quality of production. The blades are attached to the lower inner wall of the feed inlet 2, which can effectively prevent the material from blocking at the feed inlet 2 and ensure the continuity of production.
[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the second gear 202 forms a rotating structure through the first motor 203, and the first gear 204 forms a rotating structure through the second gear 202; the first motor 203 provides power for the rotation of the first stirring shaft 201 and the second stirring shaft 205. After the first motor 203 starts, it drives the first gear 204 through the rotation of the second gear 202, so that the entire stirring system can operate stably.
[0031] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the feed inlet 2 has a first stirring shaft 201 and a second stirring shaft 205 horizontally distributed inside. The first stirring shaft 201 forms a rotating structure through the second gear 202, and the second stirring shaft 205 forms a rotating structure through the first gear 204. The design of the dual stirring shafts can more fully stir the material, prevent the material from clumping, and ensure the uniformity of the material. For example, in the production process of aluminum-lithium alloy, uniform material helps to improve the compositional uniformity of the alloy, thereby improving product quality.
[0032] In this embodiment, as Figure 6As shown, the push plate 305 forms a horizontal sliding structure through the drive cylinder 308, and the support plate 306 is welded to the rack 310. The external structural dimensions of the rack 310 are consistent with the internal structural dimensions of the slide rail 304. The third gear 303 forms a rotating structure through the rack 310, and the rotating shaft 307 is connected to the third gear 303. The rotating plate 302 forms a rotating structure through the rotating shaft 307. The push plate 305 forms a horizontal sliding structure through the drive cylinder 308. The push plate 305 pushes the rack 310 to slide horizontally within the slide rail 304. The rack 310 drives the third gear 303 to rotate, and the rotating shaft 307 drives the rotating plate 302 to rotate, thereby realizing the dumping of materials. The cylinder-driven push plate 305 has a fast response speed and can accurately control the dumping of materials. When the weighing pressure sensor 301 detects that the material has reached a certain weight, the cylinder controller 309 can quickly control the drive cylinder 308 to work, thereby realizing the timely dumping of materials.
[0033] In this embodiment, as Figure 3 As shown, the auger conveyor shaft 102 forms a rotating structure through the third motor 101; the rotation of the auger conveyor shaft 102 can stably transport materials and avoid blockage and accumulation of materials during the transport process. For example, in the production of aluminum-lithium alloys, it can ensure that materials smoothly enter the next production process and improve production efficiency.
[0034] In this embodiment, as Figure 6 As shown, the weighing pressure sensor 301 is connected to the cylinder controller 309 via a cable, and the cylinder controller 309 is connected to the drive cylinder 308 via a cable. The cable connection is stable and reliable, ensuring accurate signal transmission. The material weight signal detected by the weighing pressure sensor 301 can be transmitted to the cylinder controller 309 in a timely manner, thereby controlling the operation of the drive cylinder 308 and realizing automated control. The drive cylinder 308 and the second motor 207 are connected to an external main control panel, which facilitates the control of the second motor 207 to stop feeding materials.
[0035] The method of use and advantages of this utility model: The feeding device for producing aluminum-lithium alloy operates as follows:
[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the first motor 203 is started first. The output shaft of the first motor 203 drives the second gear 202 to rotate. At the same time, the rotation of the second gear 202 drives the first gear 204 to rotate. The first stirring shaft 201, which is rotatably connected to the rear of the second gear 202, and the second stirring shaft 205, which is rotatably connected to the rear of the first gear 204, are horizontally distributed in the feed inlet 2 to stir the added material, prevent the material from clumping, and ensure the uniformity of the material. The stirred material enters the limiting wheel 206 from the feed inlet 2. The second motor 207 is started to drive the limiting wheel 206 to rotate. Since the outer structure of the blades of the limiting wheel 206 is attached to the lower inner wall of the feed inlet 2, the speed and amount of material entering the feed inlet 2 can be controlled, and the material falls into the rotating plate 3 below. 02. The weighing pressure sensor 301 inside the rotating plate 302 weighs the material. The weighing pressure sensor 301 transmits the signal to the cylinder controller 309 through the cable. When the weighing reaches a certain value, the cylinder controller 309 controls the drive cylinder 308 to work. The front output shaft of the drive cylinder 308 pushes the push plate 305, causing the push plate 305 to slide horizontally. The push plate 305 pushes the rack 310 to slide horizontally in the slide rail 304. The rack 310 drives the third gear 303 to rotate. The rotating shaft 307 inside the third gear 303 drives the rotating plate 302 to rotate, pouring the material into the conveyor housing 1. The third motor 101 is started. The output shaft of the third motor 101 drives the auger conveyor shaft 102 to rotate, conveying the material to the subsequent production stage.
