[0002] In the steelmaking process, accurate material measurement plays a crucial role in ensuring steel product quality, controlling production costs, and stabilizing the production process. Traditional steelmaking material weighing devices often employ relatively simple weighing modes, such as static weighing equipment. These devices require manual intervention for loading, weighing, and unloading materials, which is not only inefficient but also prone to significant human error, making it difficult to meet the stringent requirements of steelmaking processes for precise material proportions.
[0003] In practical use, it has been found that although some automated weighing equipment can achieve basic metering functions, it has shortcomings in dynamic weighing and flow control. It cannot adjust the feeding speed in real time according to the material weight, resulting in over- or under-weighing of materials, which affects the continuity and stability of steelmaking. Therefore, we propose a material metering and weighing device for steelmaking to solve the above problems. Utility Model Content

The top of the spring 302 is fixedly connected to the bottom of the metering box 4.
[0032] Specifically, the pushing mechanism includes a push rod 401 and a push plate 402. The push rod 401 is fixedly installed at the bottom of the metering box 4. The bottom end of the push rod 401 extends to the bottom of the weighing box 3. The push rod 401 is located on the left side of the weighing plate 301. The push plate 402 is fixedly installed at the bottom end of the push rod 401. The push plate 402 is slidably connected to the sliding hole 8.
[0033] Specifically, the lead screw mechanism includes a lead screw 101 and a lead screw seat 102. The same lead screw 101 is rotatably installed on the inner walls of both sides of the support box 1. The lead screw 101 is located above the sliding hole 8. The lead screw seat 102 is threaded on the lead screw 101. A slide rod 103 is fixedly installed on the right side of the lead screw seat 102. The right end of the slide rod 103 extends to the outside of the support box 1. The slide rod 103 is located between the feed box 2 and the weighing box 3. A gear mechanism is provided between the lead screw 101 and the push plate 402.
[0034] Specifically, the gear mechanism includes a rack plate 403 and a gear 404. The rack plate 403 is fixedly installed on the top of the push plate 402. The left side of the rack plate 403 is slidably connected to the inner wall of the left side of the support box 1. The gear 404 is fixedly sleeved on the lead screw 101. The gear 404 is located on the left side of the lead screw seat 102. The rack plate 403 and the gear 404 mesh with each other.
[0035] Specifically, the material control mechanism includes a feeding pipe 5 and a measuring plate 501. The feeding box 2 is provided with a feeding pipe 5 at the bottom. The measuring plate 501 is slidably installed on the left side of the feeding pipe 5. The left side of the measuring plate 501 is fixedly connected to the right side of the slide rod 103. Solenoid valves are provided on both the feeding pipe 5 and the discharge pipe 6.
[0036] Specifically, a slider 9 is provided on the left side of the push plate 402, and a sliding groove is provided on the inner wall of the left side of the support box 1. The sliding groove is located below the lead screw 101, and the slider 9 is slidably connected to the sliding groove.
[0037] Specifically, a controller 7 is installed on the front side of the support box 1, and the controller 7 is electrically connected to the weighing plate 301 and the solenoid valve.
[0038] In this application, during operation, the material is first fed into the feed box 2 through the feed inlet 201, and then slides down through the bottom feed pipe 5, falling directly into the metering box 4 below. During this process, as the material in the metering box 4 continues to accumulate, its weight continues to increase. Under the action of gravity, the metering box 4 overcomes the elastic force of the spring 302 in the weighing mechanism and slides down along the inner wall of the weighing box 3. The downward movement of the metering box 4 can drive the push rod 401 fixedly connected to it to descend synchronously. The push rod 401 then pushes the push plate 402 to move downward, so that the rack plate 403 fixed at the top of the push plate 402 also moves downward.
[0039] The rack plate 403 precisely meshes with the gear 404 on the lead screw 101. When the rack plate 403 moves downward, it drives the gear 404 to rotate based on the transmission principle of the rack and pinion, thereby driving the lead screw 101 to rotate synchronously. During the rotation of the lead screw 101, the lead screw seat 102 threaded on it moves to the right along the lead screw 101, and the slide rod 103 fixed on the right side of the lead screw seat 102 also moves to the right. The slide rod 103 pushes the control plate 501 to slide on the left side of the feed pipe 5 at the bottom of the feed box 2. As the amount of material in the metering box 4 increases and the downward distance increases, the control plate 501 gradually slides to the right, which can block the opening of the feed pipe 5, thereby slowing down the speed at which the material enters the metering box 4, realizing the dynamic adjustment of the feed flow rate, and ensuring the accuracy of the weighing process.
[0040] When the material weight reaches the set value, the metering box 4 moves down to the limit position, the spring 302 is compressed to the maximum value, the control plate 501 completely closes the feeding pipe 5, and the feeding stops automatically; at this time, the weighing plate 301 can transmit the weight signal to the controller 7, the controller 7 can close the solenoid valve on the feeding pipe 5 and open the solenoid valve on the discharge pipe 6, so that the material in the metering box 4 can be automatically discharged through the discharge pipe 6.
