Description

Technical Field

[0001] This invention relates to the field of new material measurement technology, specifically to an automatic weighing and batching device for a casting and smelting furnace. Background Technology

[0002] In the field of new material casting, especially in the production of high-performance metal matrix composites and special alloys, the accuracy, uniformity, and stability of raw material batching directly determine the microstructure and mechanical properties of the new materials. In the casting production process, the accuracy and efficiency of raw material batching in the melting furnace directly determine the compositional stability of the castings and the production pace.

[0003] Currently, most small and medium-sized casting enterprises still use manual weighing and batching. The traditional weighing mode has the following defects: 1. The measurement accuracy cannot meet the requirements of new materials. The weighing efficiency of traditional manual weighing or simple mechanical weighing devices is low. When weighing, it is necessary to gradually add or reduce the raw materials on the weighing equipment to make the weight of the raw materials on the weighing equipment meet the standard. The operation steps are cumbersome and greatly reduce efficiency. At the same time, there are many manual involvement links (weighing, unloading, conveying), which not only has high labor intensity, but is also prone to human operation errors (such as raw material spillage) affecting batching efficiency and accuracy; 2. The problem of material blockage in the silo is prominent. The raw materials will form "bridges" or blockages at the discharge end of the silo. When the above situation occurs in the traditional weighing device, the blockage will be solved by manual knocking. However, the feeding process will be interrupted between the discovery of the blockage and the arrival of the manual knocking operation.

[0004] Therefore, there is an urgent need for an automatic weighing and batching device for casting and smelting furnaces that can improve weighing efficiency, in order to solve the defects of existing technologies in the process of new material batching and metering. Summary of the Invention

[0011] In a preferred embodiment of the automatic weighing and batching device for the casting and smelting furnace of the present invention, the support frame rod includes a mounting plate that is installed on the rear end guard plate of the support seat by screws and a mold frame rod that is welded to the mounting plate. A sleeve block is welded to the upper end of the mold frame rod.

[0012] As a preferred embodiment of the automatic weighing and batching device for the casting and smelting furnace of the present invention, the vibration following arm includes a square rod movably inserted into the sleeve block and a widened contact block fixedly welded to one end of the square rod. The other end of the square rod is detachably mounted with a stop block by screws. A spring is fitted on the square rod, one end of which is connected to the stop block and the other end is connected to the sleeve block. The cross-sectional dimensions of the square rod are matched with the opening dimensions of the sleeve block.

[0013] As a preferred embodiment of the automatic weighing and batching device for the casting and smelting furnace of the present invention, the striking arm includes a vertical support rod fixedly welded to the upper end face of the square rod and a sleeve block two welded to the upper end of the vertical support rod. The square rod two is movably inserted into the sleeve block two, and a locking bolt is threaded on the upper end of the sleeve block two. A rubber striking block is fixedly connected to one end of the square rod two, and the rubber striking block contacts the rear end of the guide square tube. The cross-sectional dimensions of the second square rod match the opening dimensions of the second sleeve block.

[0014] As a preferred embodiment of the automatic weighing and batching device for the casting and smelting furnace of the present invention, the weighing unit includes a weighing component installed on the second platform and a lifting frame installed on the first platform, wherein a pusher plate is installed on the lifting frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The vibrating motor and elastic support leg structure of the vibrating feeder guide trough generate stable vibration, realizing the vibratory feeding of raw materials and conveying them to the receiving trough of the weighing department. This achieves automated metering of raw materials, which greatly improves weighing efficiency compared with traditional manual weighing methods. At the same time, the weighed raw materials are automatically unloaded by the pusher plate, replacing the traditional manual unloading operation. This improves efficiency and reduces labor intensity. On the other hand, it avoids the situation where raw materials are spilled and reduce weighing accuracy due to manual unloading. After being pushed out of the receiving trough, the raw materials fall onto the conveyor belt, which then transports the weighed raw materials to the loading box.

[0017] 2. By using the mechanical contact structure between the auxiliary hammering of the material feeding component and the mechanical contact of the boom and the guide chute, no additional power source is required. The hammering action is directly driven by the energy of the feeding vibration, reducing equipment energy consumption and subsequent maintenance costs. The hammering of the guide tube prevents the raw material inside the guide tube from becoming blocked. Moreover, the hammering of the guide tube is continuous during the feeding process, which can effectively avoid the blockage of the guide tube and thus prevent feeding interruption.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] This invention provides a technical solution: such as Figure 1 - Figure 12 The automatic weighing and batching device for a casting smelting furnace is shown. The automatic weighing and batching device of the present invention belongs to the field of new material metering. It includes a support frame 100, which includes a main frame 110 and a first platform 120 and a second platform 130 welded to the main frame 110. A storage hopper 200 and a vibrating feeder 300 installed on the first platform 120 are installed on the main frame 110, and a weighing part 400 is installed on the second platform 130. A conveyor belt 500 is fixedly installed below the weighing part 400. The conveyor belt 500 is used to transport the weighed raw materials to the loading box. The vibrating feeder 300 includes a support base 310 and a vibrating feeder guide 320 mounted on the support base 310. One end of the vibrating feeder guide 320 is located below the discharge end of the storage hopper 200, and the other end is located above the weighing unit 400. An auxiliary striking discharge component 330 is also mounted on the back of the support base 310. Two sets of arms are provided at the upper end of the auxiliary striking discharge component 330. The two sets of arms are in contact with the vibrating feeder guide 320 and the discharge end of the storage hopper 200, respectively. The vibrating feeder guide 320 vibrates and drives the arms in contact with it, thereby driving the other set of arms to strike the discharge end of the storage hopper 200.

[0022] like Figure 4 - Figure 6 As shown, the storage hopper 200 includes a hopper body 210 and a discharge guide 220 connected and installed at the lower end of the hopper body 210. The discharge guide 220 is located above the vibrating feed guide 320. The discharge guide 220 includes a guide square tube 221 connected to the hopper opening at the lower end of the hopper body 210. The lower end of the guide square tube 221 is inclined. A discharge opening 222 is provided at the inclined structure at the lower end of the guide square tube 221. An adjusting baffle structure is movably provided on the outer side of the tube wall at the upper end of the discharge opening 222. The adjusting baffle structure includes a plate 223 provided on the outer side of the tube wall. An adjusting limit slot 224 is provided on the plate 223. A threaded post 225 is inserted into the adjusting limit slot 224. One end of the threaded post 225 is fixedly welded to the outer side of the tube wall. A locking nut 226 is threaded on the threaded post 225.

[0023] The baffle structure controls the falling speed of the raw material by blocking the discharge opening 222. Combined with the uniform vibration of the guide trough 321, it ensures that the raw material enters the weighing section 400 at a stable flow rate, avoiding weighing errors caused by feeding too fast or affecting efficiency by feeding too slow.

[0024] like Figure 5 - Figure 10As shown, the support base 310 includes a base plate 311 and a reinforcing block 312 fixedly welded to the upper surface of the base plate 311. A protective plate 313 is installed around the base plate 311, and the auxiliary hammering blank 330 is installed on the protective plate 313 at the rear end.

[0025] The vibrating feed guide 320 includes a feed trough 321 and a connecting plate frame 322 welded to the lower end of the feed trough 321. One end of the connecting plate frame 322 is an inclined surface, and a mounting base 323 is fixedly welded to the inclined surface. A vibrating motor 324 is detachably mounted on the mounting base 323 by bolts. Elastic support leg structures are fixedly provided at both ends of the lower end face of the feed trough 321. The elastic support leg structure includes a spring 325 and connecting blocks 326 fixedly welded to both ends of the spring 325. The connecting block 326 at the upper end of the spring 325 is fixedly welded to the lower end face of the feed trough 321, and the connecting block 326 at the lower end of the spring 325 is fixedly welded to the upper end of the reinforcing block 312.

[0026] The auxiliary striking component 330 includes a support frame rod 331 connected to the guard plate 313 at the rear end of the support base 310 and a movably plugged-in vibration follower arm 332 installed on the upper end of the support frame rod 331. One end of the vibration follower arm 332 contacts the rear end of the guide trough 321, and the upper end of the vibration follower arm 332 is connected to a striking arm 333 for striking the rear end of the guide square tube 221.

[0027] Furthermore, the support rod 331 includes a mounting plate 331a that is installed on the rear end guard plate 313 of the support base 310 by screws and an L-shaped rod 331b welded to the mounting plate 331a. A sleeve block 331c is welded to the upper end of the L-shaped rod 331b.

[0028] Furthermore, the vibration following arm 332 includes a square rod 332a that is movably inserted into the sleeve block 331c and a widened contact block 332b that is fixedly welded to one end of the square rod 332a. The other end of the square rod 332a is detachably mounted with a stop block 332c by screws. A spring 332d is fitted on the square rod 332a. One end of the spring 332d is connected to the stop block 332c and the other end is connected to the sleeve block 331c. Among them, the cross-sectional dimensions of square rod 332a match the opening dimensions of sleeve block 331c.

[0029] By using the spring 332d structure on the vibration follower arm 332, the impact of the vibration of the guide trough 321 is buffered, making the reciprocating motion of the square rod 332a more stable. On the other hand, it provides elastic reset power to ensure that the striking frequency matches the vibration frequency of the guide trough 321.

[0030] Furthermore, the striking arm 333 includes a vertical support rod 333a fixedly welded to the upper end face of the square rod 332a and a sleeve block 333b welded to the upper end of the vertical support rod 333a. A square rod 333c is movably inserted into the sleeve block 333b. A locking bolt 333d is threaded onto the upper end of the sleeve block 333b. A rubber striking block 333e is fixedly connected to one end of the square rod 333c. The rubber striking block 333e is connected to the guide... The rear end of the material square tube 221 contacts the adjustable assembly structure of the square rod 333c and sleeve 333b on the striking arm 333. This allows for flexible adjustment of the distance between the rubber striking block 333e and the material guide square tube 221, thereby adjusting the striking force. When the rubber striking block 333e is farther from the material guide square tube 221, the striking force is smaller; when the rubber striking block 333e is closer to the material guide square tube 221, the striking force is larger. Simultaneously, the material design of the rubber striking block 333e, which assists in striking the material discharge component 330, buffers the impact force, preventing the material guide square tube 221 from deforming or cracking due to long-term high-frequency striking, thus improving the structural stability of the hopper discharge end and the overall service life of the equipment.

[0031] The cross-sectional dimensions of square rod 2 333c match the opening dimensions of sleeve block 2 333b.

[0032] By using the vibration of the auxiliary striking component 330 to follow the mechanical contact structure between the arm 332 and the guide trough 321, the striking action is driven directly by the energy of the feeding vibration without the need for an additional power source, reducing equipment energy consumption and subsequent maintenance costs. The striking action on the guide tube 221 prevents the raw material inside the guide tube 221 from becoming blocked. Moreover, the striking of the guide tube 221 is continuous during the feeding process, which can effectively prevent the guide tube 221 from becoming blocked and thus prevent feeding interruption.

[0033] like Figure 4 and Figure 11 - Figure 12 As shown, the weighing unit 400 includes a weighing component 410 mounted on a second platform 130 and a lifting platform 420 mounted on a first platform 120. A pusher plate 430 is mounted on the lifting platform 420. The weighing component 410 includes an electronic scale 411 mounted on a platform 130 and a receiving groove 412 connected to the weighing platform of the electronic scale 411. The push plate part of the pusher plate 430 is disposed in the receiving groove 412 and is used to push out the raw material in the receiving groove 412.

[0034] The electronic scale 411 and the vibration motor 324 are linked through an electronic control system. It should be noted that the electronic control system linkage is an existing technology and can be controlled by PLC programming. When the weight of the raw material in the receiving trough reaches 90% of the preset value, the vibration motor 324 can be controlled to reduce its power and reduce the feeding speed, so as to combine coarse feeding and fine feeding and further improve the metering accuracy.

[0035] The pusher plate 430 includes a pusher plate body 431 movably disposed in the receiving groove 412 and a connecting crossbar 432 for connecting the pusher plate body 431. A connecting lug 433 is fixedly welded to the middle of the connecting crossbar 432. The two ends of the connecting crossbar 432 are connected to the pusher plate body 431 by screws. The pusher plate body 431 is provided with a locking head 434 at both ends for engaging with the groove edge of the receiving groove 412. An electric telescopic rod 435 is installed on the lifting platform 420. The telescopic end of the electric telescopic rod 435 is connected to the connecting lug 433.

[0036] The vibrating motor 324 and the elastic support leg structure of the vibrating feed guide 320 cause the guide trough 321 to generate stable vibration, realizing the vibratory feeding of the raw materials and conveying the raw materials to the receiving trough 412 of the weighing unit 400, realizing the automated metering of the raw materials. Compared with the traditional manual weighing method, the weighing efficiency is greatly improved. At the same time, the weighed raw materials are automatically unloaded by the pusher plate 430, replacing the traditional manual unloading operation. On the one hand, it improves efficiency and reduces labor intensity. On the other hand, it can avoid the situation of raw materials spilling and reducing weighing accuracy caused by manual unloading. After being pushed out of the receiving trough 412, the raw materials fall onto the conveyor belt 500, and the conveyor belt 500 transports the weighed raw materials to the loading box.

[0037] Working principle: The raw materials are stored in the silo 210, and the discharge rate is preset by adjusting the baffle structure.

[0038] After the vibration motor 324 starts, it transmits vibration energy to the guide trough 321. The elastic support leg structure buffers the vibration impact on the one hand, and makes the guide trough 321 vibrate stably on the other hand, so as to promote the uniform forward conveying of raw materials in the trough.

[0039] The vibration of the guide trough 321 is transmitted to the auxiliary striking component 330 through mechanical contact, achieving the anti-blocking function without additional power. When the guide trough 321 vibrates, its rear outer wall continuously collides with the widened contact block 332b of the vibration follower arm 332, transmitting the vibration energy to the square rod 332a. The square rod 332a is movably inserted into the sleeve block 331c. Under the combined action of the vibration energy and the elastic force of the spring 332d, the square rod 332a performs a high-frequency reciprocating linear motion along the sleeve block 331c. The reciprocating motion of the square rod 332a is transmitted to the sleeve block 333b through the vertical support rod 333a, thereby driving the square rod 333c to reciprocate synchronously. The rubber striking block 333e continuously strikes the rear wall of the guide square tube 221 to prevent blockage.

[0040] The electronic scale 411 collects the weight of the raw material in the receiving trough 412 in real time. After the preset value is reached, the vibration motor 324 stops, completing a single measurement.

[0041] The electric telescopic rod 435 drives the push plate 431 to push the metered raw material to the conveyor belt 500, and the conveyor belt 500 transports the weighed raw material into the loading box.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
