Description

Technical Field

[0001] This application relates to the field of steel fiber reinforced concrete processing technology, specifically to a steel fiber metering and feeding device. Background Technology

[0002] In the field of steel fiber reinforced concrete processing, the feeding of steel fibers is crucial. Traditional methods often involve manual feeding, such as manually pouring bagged steel fibers directly into the hopper or conveyor belt. This method has many drawbacks. Manual operation is not only labor-intensive but also prone to repeated feeding or omissions, resulting in poor metering accuracy. Furthermore, the slender, irregular shape and poor flowability of steel fibers make them difficult to break up manually, easily leading to clumping. This prevents the steel fibers from being evenly and fully premixed with the aggregate, affecting the mixing effect of the steel fiber reinforced concrete and hindering the effective enhancement of tensile, flexural, and impact resistance properties of the concrete. It may even cause localized strength weakening.

[0003] A patent document with publication number CN215619107U, known to the inventor, discloses an automatic steel fiber feeding system for a UHPC mixing device. This device automatically lifts a whole bag of steel fibers using an electric hoist, and automatically breaks the bag using a bag-breaking device in the middle of the support, allowing the steel fibers to fall into a vibrating steel fiber scale at the lower end of the support. While weighing and measuring, the steel fiber scale breaks up clumps of fibers through vibration, improving flowability. The weighed steel fibers are then transported to the feed inlet of the mixing host by a belt conveyor. The entire system is controlled in conjunction with an electronic control system.

[0004] However, in the process of implementing the technical solutions in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems: First, each functional module of the device is relatively independent, which makes the device too large and the integration is not high; second, the material falling of the device is only achieved by the weight of the material itself and the vibration of the vibrating steel fiber scale, such a single solution is prone to material accumulation and jamming; in addition, the weighing body of the vibrating steel fiber scale and the support are only rigidly fixedly installed through the weighing component, and the vibration of the device will cause the support to shake or the components to resonate, which will accelerate the fatigue damage of the mechanical components and also have a negative impact on the accuracy of the weighing component.

[0005] In summary, existing feeding devices still have significant shortcomings in terms of integration, operating efficiency, and long-term reliability, and there is an urgent need for a new type of device that can achieve high precision, high efficiency, and high stability.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the background technology of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0007] In view of at least one of the above technical problems, this disclosure provides a steel fiber metering and feeding device, which uses a hook scale to lift a weighing body equipped with a vibrating motor and a toothed roller, thereby completing high-precision feeding of steel fibers and solving the shortcomings of the prior art in terms of integration, operating efficiency and long-term reliability.

[0008] According to one aspect of this disclosure, a steel fiber metering and feeding device is provided, comprising a frame and a hopper suspended within the frame by a hook scale.

An angled partition plate is provided at the center of the inner side of the hopper, which divides the interior of the hopper into a filling space above the partition plate, two distribution channels on both sides of the partition plate, and a storage space below the partition plate. Vibrators are provided on the outer wall of the hopper corresponding to the two distribution channels. Toothed rollers for extruding and shearing steel fibers into single strands or small bundles are provided at both the two distribution channels and the feeding port.

[0009] Furthermore, the steel fiber metering and feeding device also includes a controller electrically connected to the hook scale for controlling the shutdown of the control device.

[0011] Furthermore, the hook scale is connected to the hopper via a steel wire rope, and the hook scale is located directly above the center of gravity of the hopper.

[0012] Furthermore, the motor and the toothed roller are connected by a speed reducer.

[0013] Furthermore, both the motor and the vibrator are fixed to the outside of the side wall of the hopper by a mounting plate, and the vibration direction of the vibrator is perpendicular to the side wall of the hopper.

[0014] One or more technical solutions provided in the embodiments of this application have at least one of the following technical effects or advantages:

[0015] 1. The multi-degree-of-freedom design of the hook scale for lifting the weighing body effectively solves the problem of mechanical parts being easily affected by vibration and thus accelerating fatigue damage in existing technologies. This enables high-precision measurement of materials, extends the life of the device, and reduces equipment maintenance costs.

[0016] 2. The weighing body, designed with a combination of a vibrating motor and toothed rollers, effectively solves the problem of material accumulation and jamming in existing technologies, thereby improving the production efficiency of the equipment and reducing maintenance costs.

[0017] 3. By integrating the weighing device and the dispersing device onto the weighing body, the problem of the large size of the device in the existing technology is effectively solved, thereby expanding the application scenarios of the equipment and reducing the production cost of the equipment.

It provides a solution for feeding devices with higher precision, wider scenario adaptability, and longer service life. Attached Figure Description

[0029] To better understand the technical solution of this application, the above technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] Structural Description:

[0032] This example discloses a steel wire metering and feeding device; see [link to documentation]. Figure 1 It includes a device frame 2 and a feeding mechanism 1, which is fixed to the steel pipe on the upper part of the frame 2 by a ring lock.

[0033] Specifically, the main body of the feeding mechanism 1 is a hollow hopper 11, which is composed of an upper cuboid and a lower inverted truncated square. The hopper 11 is connected to the hook below the hook scale 13 by a steel wire rope 12, and then fixed to the frame 2 of the entire device by the ring lock above the hook scale 13.

[0034] A distribution baffle 115 is welded to the center of the lower half of the truncated pyramid of the hopper 11. The baffle 115 diverts the steel fibers entering the device from the feed inlet above the hopper 11 to the front and rear sides, dividing the hopper 11 into two channels. At the end of the distribution baffle 115, it combines with the hopper 11 to form the outlets of the two channels, each outlet equipped with a set of toothed rollers. This combination not only restricts the fall of the steel fibers within the device but also breaks up any clumps of steel fibers. At the bottom outlet of the lower half of the truncated pyramid of the hopper 11, a set of toothed rollers is also provided for limiting and breaking up the steel fibers.

[0035] One side of each of the three sets of toothed rollers is powered and fixed by an electric motor, while the other side is fixed by a bearing-mounted shaft. The electric motor converts the high-speed, low-torque power into a low-speed, high-torque force via a worm gear reducer and transmits it to the toothed rollers. The motor and reducer assemblies of the two sets of toothed rollers located at the end of the material distribution baffle 115 are positioned opposite each other on the left and right sides of the outer side of the hopper 11. The toothed roller motor and reducer at the bottom outlet of the truncated pyramid are also located on the same side of any of the above motors on the hopper 11. All the above motors and reducers are bolted to the upper surface of the mounting plate, which is welded to the corresponding position on the side of the hopper 11.

[0036] Vibrators fixed by mounting plates are installed on the front and rear sides of the lower half of the truncated quadrangular section of the hopper 11.

[0037] Workflow:

[0038] Steel fiber raw materials are fed into hopper 11 and enter two channels separated by a distribution baffle 115. The first toothed roller 1513 and the second toothed roller 1523 installed at the channel openings prevent further descent. Dividing the material into two channels allows for more precise control over its state, resulting in more dispersed fibers. After all the steel fiber raw materials are fed into hopper 11, the equipment is started. The hook scale 13 records the total weight of the currently lifted equipment as A1. Then, the vibrator and motor operate simultaneously.

[0039] The motors of the first toothed roller 1513 and the second toothed roller 1523 located at the channel exit drive the toothed rollers to rotate through a reducer. Through extrusion and shearing, the steel fiber raw material is coarsely processed to break up any lumps or agglomerations that may exist in the steel fiber raw material, dispersing it into single fibers or small bundles to avoid accumulation or jamming during feeding. At the same time, the rotational speed of the toothed rollers is dynamically adjusted by the motor speed interval based on the weight displayed by the current hook scale, making the steel fiber conveying more uniform and achieving quantitative feeding of steel fiber, ensuring the accuracy of the proportion of steel fiber added to matrix materials such as concrete and mortar.

[0040] The vibrator eliminates the "bridging" caused by static electricity in the steel fiber raw material in the hopper 11 through high-frequency vibration, and reduces the friction between the steel fiber and the inner wall of the equipment. The auxiliary toothed roller delivers the steel fiber evenly to the bottom, preventing the steel fiber from hooking together or sticking together, which can cause uneven feeding and ensure the long-term stable operation of the equipment.

[0041] The first toothed roller 1513 and the second toothed roller 1523 primarily address the physical dispersion and quantitative conveying of steel fibers, while the vibrator focuses on optimizing the flow state of the steel fibers. The combination of these two components prevents steel fiber agglomeration, ensures uniform distribution of individual fibers, and prevents material jamming and bridging, guaranteeing continuous production. Through a dual mechanism of mechanical crushing (toothed rollers) and vibration assistance (vibrator), the combination of these two components precisely controls the amount of fiber incorporated, meeting the performance requirements of the engineering project for steel fiber reinforced materials.

[0042] After initial processing by the first toothed roller 1513 and the second toothed roller 1523, the falling steel fibers land above the third toothed roller 1533 at the bottom. After secondary extrusion and shearing by the third toothed roller 1533, the steel fibers that have been coarsely processed by the two different toothed rollers 1513 and 1523 are further finely processed, making the steel fibers discharged through the third toothed roller 1533 discharge device more dispersed and the amount of feed more uniform.

[0043] The amount of steel fiber required for this concrete is A2. The controller is a subtraction meter that is electrically connected to the hook scale 13, the motor, and the vibrator. It monitors the weight A3 displayed on the hook scale 13 in real time. After a period of feeding, when the weight A3 displayed on the hook scale 13 equals A1 - A2, the weight of the fed material is exactly the weight of the steel fiber required for the concrete, and the subtraction meter controls the equipment to stop operating.
