Description

Technical Field

[0001] The utility model belongs to the technical field of powder feeding and conveying, and relates to an ultra-light powder closed flip bag clamping feeding device and method. Background Art

[0002] In the fields of chemical industry, mining and building materials, powders are often used as key materials or raw materials, so the research on powder feeding and conveying technology has important practical significance.

[0003] Ultra-light powder refers to a powder with a density range of 0.01-0.5g / cm 3 Powdered substances with fine particle sizes between the two have physical properties that make them show significant differences in weight and volume. Ultra-light powders usually have a high specific surface area and excellent dispersibility, which makes them have broad application prospects in materials science, chemical industry, electronics, medicine and other fields. There are various preparation methods, including vapor deposition, liquid precipitation and mechanical synthesis. By finely controlling the process parameters, ultra-light powder materials with uniform particle size and stable performance can be obtained. Research and application of ultra-light powders can not only optimize material properties, but also achieve the goal of energy conservation and emission reduction in industrial production.

[0004] For the feeding of ultra-light powder, multiple factors need to be considered. First, ultra-light powder has expansion and fluidity, which means that attention should be paid to the flow uniformity and metering accuracy of the powder during the feeding process, which has a very important impact on the product quality and stability during the processing. On the other hand, since ultra-light powder is easy to generate dust and static electricity during the feeding process, corresponding protective measures need to be taken to ensure the safety of operators and the cleanliness of the production environment.

[0005] Therefore, the research on ultra-light powder feeding and conveying technology is of great significance for improving production efficiency, ensuring product quality, and protecting the safety and cleanliness of the working environment. In summary, the safe and reliable conveying of ultra-light powders is still one of the technical difficulties that need to be overcome in the current powder engineering field. Future research will continue to explore efficient feeding and conveying systems to solve the challenges in the metering and conveying process of ultra-light powders.

[0006] The invention patent with publication number CN 109353843 A discloses a powder feeding device, which includes a main silo and a feeding device. The feeding device uses a flat helical spring as a transmission component for the powder. The flat helical spring is formed by spirally winding an elastic strip, which effectively avoids the stratification of the powder and ensures the stability of the powder output quality. However, the design does not fully consider the dust problem of the powder during the transmission process, which may pose a potential threat to the health of the operator. Utility Model Content

[0007] In view of the limitations of the current ultra-light powder feeding technology, the utility model proposes an ultra-light powder closed flip bag clamping feeding device and method. The device is specially designed for ultra-light powder materials that are very easy to generate dust during the feeding process, aiming to realize the automatic feeding of ultra-light powder and avoid the generation of dust.

[0008] The technical solution of the utility model is: a closed flip bag clamping and feeding device for ultra-light powder, including bag clamping component A, bag clamping component B, double-axis cylinder, bag clamp blanking valve, rotating locking plug plate, spindle dust cover, rotating plate, gearless slewing bearing, motor reducer, guide slider A, dustproof shell, electric control box, profile moving platform, drag chain, linear cylinder A, guide slider B, linear cylinder B, movable flange, three-axis cylinder, silicone hose, feeding pipe, magnetic sensor, rubber sealing strip and moving support plate. The bottom edge of bag clamping component A is covered with a rubber sealing strip, which ensures the sealing of the device while softly contacting with the nylon bag to avoid damage to the nylon bag. Two double-axis cylinder bodies are symmetrically fixedly installed on the side. The symmetrical arrangement can make the bag clamping force more uniform and less likely to leak. The upper end of bag clamping component B is fixedly connected to the movable end of the double-axis cylinder by screws, and the lower port is connected to the bag clamp blanking valve. The two outriggers of the rotating locking plug plate are inserted into the side ears of the bag clamping part A and fixed with screws. The crossbeam is sleeved in the groove of the rotating plate. The rotating plate is fixedly connected to the gearless slewing bearing. The outer ring of the gearless slewing bearing is fixed to the inner plate of the moving support plate. The inner ring is sleeved with the motor shaft and locked for rotation by a key. The outer plate of the moving support plate is equipped with a motor reducer. The two side plates are fixed on the guide rail slider A and can move up and down with the slider. The lower side is connected to the moving end of the linear cylinder B.

[0009] To prevent a small amount of scattered dust from entering the inside of the flipping moving parts and causing motion failures, the parts involved in the flipping movement are installed inside the dustproof housing, and the outer side of the rotating plate is covered with a spindle dust cover to minimize the impact of dust. The dustproof housing and the electric control box are fixed on the profile moving platform, one end of the drag chain is connected to the electric control box, and the other end is connected to the fixed frame. The profile moving platform is installed as a whole on the guide rail slider B and is fixedly connected to the moving end of the linear cylinder A.

[0010] The cylinder bodies of the linear cylinder A and the three-axis cylinder are fixed, the ribs at the bottom of both sides of the movable flange are fixedly connected to the moving end of the three-axis cylinder, the lower end of the pipe is softly connected to the silicone hose, and the lower end of the silicone hose is connected to the outside of the material conveying pipeline. The silicone hose is lantern-shaped as a whole, with equal-diameter circular tubes at both ends and an ellipsoidal structure in the middle. This design enables the silicone hose to be folded and stretched to a certain extent, adapting to the movement of the three-axis cylinder, ensuring the precise docking of the discharge port, and avoiding leakage during the discharge process.

[0011] The bag clamping device includes a bag clamping component A, a bag clamping component B, a rubber sealing strip, a double-axis cylinder, and a bag clamp blanking valve. The bag clamping component B is a bell-mouth structure as a whole, and the inclination angle of its cone surface is not less than the collapse angle of the added material to ensure that the material falls smoothly. The lower end hole of the bag clamping component A and the upper end hole of the bag clamping component B have the same diameter, which effectively avoids the problem of dust accumulation on the steps. In addition, the outer side of the bottom edge of the bag clamping component A is coated with a rubber sealing strip, which is intended to form a soft contact with the material bag, prevent the material bag from being damaged, and ensure the sealing of the bag clamping device. In the initial state, the bag clamping component B is located above the bag clamping component A, the bag clamping device is inverted, the double-axis cylinder is at the stroke limit position, the bag clamping component A is separated from the bag clamping component B, and the bag clamp blanking valve is in a closed state.

[0012] The described dual-axis cylinder, linear cylinder A, linear cylinder B, and three-axis cylinder are all equipped with magnetic sensors at appropriate positions at both ends of the cylinder body, and magnetic coils are built into the cylinder pistons. When the piston moves to the magnetic sensor position, the magnetic sensor detects the magnetic change and then generates an excitation signal to feed back to the control system, thereby controlling the movement and stop of the cylinder. The specific installation position of the magnetic sensor depends on the structural size of the device, and the two sensors correspond to the travel limit position and the return limit position respectively.

[0013] The utility model is a super light powder closed flip bag clamping feeding device, the main principle and working process of which include:

[0014] Step 1: Press the start control button to trigger the linear cylinder A to drag the device forward as a whole to its stroke limit, and place the nylon bag filled with added materials vertically on the external platform. The platform should be located directly below the bag clamping device after the device reaches the stroke limit of the linear cylinder A. The bag clamping device is in the initial state at this time. To ensure the normal operation of the device, the weight range of each bag of material should be controlled between 1 and 30 kg. Too small a weight can easily lead to material bridging, while too large a weight may exceed the load-bearing capacity of the cylinder, making the flipping action impossible to complete. The maximum reversal weight depends on the load-bearing capacity of the dual-axis cylinders installed on both sides of the bag clamping component A. If the maximum load-bearing weight needs to be increased, the cylinder of appropriate specifications can be replaced to meet the needs;

[0015] Step 2: Linear cylinder B is at the maximum stroke limit at the beginning. At this time, the bag clamping device is at the highest position. Press the vertical position adjustment button, and the linear cylinder B drives the bag clamping device to slowly descend as a whole, so that the powder material bag enters the interior of the bag clamping component A from the lower opening of the bag clamping component A. The device has good compatibility and high versatility with material bags, and has no special requirements for the bag body shape and material. It only needs to meet the requirement that the bag opening size is larger than the lower port size of the bag clamping component A, so that the two bag clamping components can be tightly buckled around the material bag to prevent material leakage. If the material bag has special size requirements, the lower port size of the bag clamping component A can be adjusted to meet the needs. Linear cylinder B stops after descending to the return limit position. This return limit position should meet the following requirements: the powder material bag opening is located in the space between the bag clamping component A and the bag clamping component B. Position near the midpoint of the gap; then open the powder material bag, open the bag opening and cover the side of the bag clamping part A covered with the rubber sealing strip, then press the bag clamping control button, and the double-axis cylinder resets to the return limit position. This limit position should meet the following requirements: the bag clamping part A and the bag clamping part B are tightly fastened to prevent the powder from escaping and raising dust; the bag clamping part A and the bag clamping part B are tightly fastened, and the bag opening of the material bag is clamped between the two parts to achieve bag clamping; then the program controls the linear cylinder B to slowly rise to the stroke limit position and then stop. This limit position should meet the following requirements: the material bag is completely separated from the external platform, and after the bag clamping device is flipped, the bottom of the bag clamping device's blanking valve is 3-5mm away from the top of the movable flange. If the distance is too large, it is easy to cause inaccurate subsequent docking, and if the distance is too small, it may cause interference between the devices during the flipping process;

[0016] Step 3: The motor reducer starts and rotates half a circle, so that the bag clamping device and the powder material bag are turned over. At this time, the bag clamping device returns to the upright position, and the powder material bag is in an inverted state; after the motor rotates to the right position, the linear cylinder A starts again, and the dragging device moves backward as a whole to its return limit position and then stops. Its return limit position should meet the following requirements: the coaxiality deviation between the valve hole of the bag clamp blanking valve and the inner hole of the movable flange does not exceed 1mm. Too large deviation will cause the subsequent docking action to fail. Then the three-axis cylinder moves to the stroke limit position, driving the movable flange to move upward to complete the docking with the bag clamp blanking valve. Its stroke limit position should meet the following requirements: after docking, the variable-diameter straight pipe at the lower part of the bag clamp blanking valve extends into the inside of the movable flange by no less than 5mm to prevent dust from escaping;

[0017] Step 4: After the docking is completed, open the bag clamp drop valve and the material falls; after completion, press the reset button and all components automatically return to the starting state and wait for the next working cycle.

[0018] The utility model discloses a closed flip bag clamping feeding device for ultra-light powder, which has the following advantages and positive effects: 1. It realizes the transformation of ultra-light powder feeding from manual operation to mechanical automation operation, greatly improving production efficiency; 2. The feeding process is completed under nearly closed conditions, which effectively solves the problem of ultra-light powder being easy to generate dust, and greatly reduces the harm and impact on operators and the environment; 3. The feeding process is fast and efficient, and workers can complete the feeding independently without physical labor in the process, which greatly reduces the labor intensity of workers; 4. The device has good compatibility with material bags, and has no requirements on the shape and material of the material bags, which greatly improves the universality of the device.
