Description

Technical Field

[0001] This utility model relates to the field of spinning fiber cutting technology, specifically a short fiber guiding and cutting device. Background Technology

[0002] In modern industrial systems, spun fibers are widely used in textiles, aerospace, and many other fields, with their production, processing, and use spanning numerous links in the industrial chain. However, with the large-scale application of fiber materials, occupational health problems caused by fine fibers are becoming increasingly serious, posing a significant challenge to industry development and personnel safety.

[0003] During the production, processing, and use of textile fibers, a large number of fine fibers are inevitably generated. These fibers are easily dispersed in the work environment due to factors such as airflow and mechanical vibration. When operators accidentally inhale these fibers, they may deposit in the lungs, damaging the normal physiological structure of the lungs, causing lung infections, and even significantly increasing the risk of lung cancer. Simultaneously, long-term exposure to fiber dust can cause continuous irritation to the respiratory mucosa, leading to irreversible respiratory diseases such as chronic bronchitis and emphysema. Furthermore, fine fibers adhering to the skin surface can trigger allergic reactions, causing irritant symptoms such as redness, swelling, itching, and rashes, seriously affecting the health and work efficiency of operators.

[0004] Currently, most fiber cutting devices on the market suffer from design flaws. Traditional devices, lacking effective fiber restraint and collection mechanisms, are prone to fiber splattering during the cutting process. On one hand, the mechanical force generated during cutting ejects fibers into the surrounding space, creating high concentrations of fiber dust; on the other hand, the fibers themselves are small and lightweight, easily dispersed by air currents, further exacerbating fiber diffusion in the work environment. Operators are exposed to high-risk health threats through frequent contact with splattered fibers, and existing devices are no longer sufficient to meet stringent occupational health and safety requirements.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-7 This utility model provides a technical solution: A short fiber guiding and cutting device includes a housing 1, an upper structure 2 installed at the top inside the housing 1, and a lower structure 3 installed at the bottom inside the housing 1. A guide tube 4 is provided on one side of the upper structure 2, and a grounding tray 5 is provided on the side of the lower structure 3 opposite to the guide tube 4. The port of the guide tube 4 is a feed inlet 6, and a discharge outlet 7 is provided on the housing 1 corresponding to the grounding tray 5. Bundles of textile fibers can be fed into the device through the feed inlet 6, and short fiber filaments cut by the cutting device can be output through the discharge outlet 7.

[0018] Furthermore, the upper structure 2 includes a cutting wheel 8 and a motor 9. The motor 9 is mounted on the side wall of the outer casing 1, and the cutting wheel 8 is mounted on the motor 9. The motor 9 must be a servo motor. By controlling the rotation speed of the motor 9 and the feed speed at the feed port 6, the cutting length of the material can be controlled. That is, the time required for the two sets of cutting blades 12 to rotate by the rotation speed can be calculated. Multiplying this time by the linear velocity of the material input at the feed port 6 yields the length of the material after cutting.

[0019] Furthermore, the cutting disc 8 includes a structural disc 10, a structural ring 11, and cutting blades 12. The structural disc 10 is mounted on the motor 9, and the structural ring 11 is located at the bottom of the structural disc 10. The structural disc 10 and the structural ring 11 are welded together via connecting posts 13. Cutting blades 12 are mounted on multiple sets of connecting posts 13. The cutting blades 12 are detachable and replaceable, and should be replaced promptly after wear from prolonged use.

[0020] Furthermore, the lower structure 3 includes an electrostatic adsorption plate 14, an inclined slide 15, and a grounding tray 5. An electrostatic adsorption plate 14 is provided on one side of the outer shell 1 corresponding to the cutting wheel 8. An inclined slide 15 is provided at the bottom of the electrostatic adsorption plate 14, and a grounding tray 5 is provided on the other side of the inclined slide 15. The electrostatic adsorption plate 14 is an anode electrostatic adsorption plate. Utilizing anode electrostatic energy, airborne particles and fibers are adsorbed onto the electrostatic adsorption plate 14 by electrostatic action, and then fall to the lower chassis under gravity. The opening of the chassis is connected to an inclined slide 15, allowing fibers to slide along the inclined slide 15 onto the electrostatic adsorption plate 14. The inclined slide 15 is recommended to be made of a non-metallic material with poor conductivity. If the inclined slide 15 is conductive, electrostatic adsorption will make it difficult for materials to slide down from the inclined slide 15. The electrostatic adsorption plate 14 is an adsorption electrode plate based on the principle of electrostatic adsorption. It is recommended to use the core of the existing DYQ501Ⅱ plate electrostatic precipitator. Alternatively, a high-voltage electrostatic generator can be used with the adsorption electrode plate (flat metal plate), such as the SIMCO-ION CM20 high-voltage electrostatic generator (commonly used in industrial electrostatic adsorption to recover precious metal powders). In this invention, the power of the device used for adsorbing fibers needs to be increased. The SIMCO-ION CM20 has high power, and some air purifiers' electrostatic adsorption devices cannot be upgraded to meet the fiber adsorption requirements.

[0021] Furthermore, the grounding tray 5 is made of a highly conductive metal material, and a conductive wire is provided at the bottom of the grounding tray 5 to connect to the ground. The grounding tray 5 is equipped with a ground wire to eliminate static electricity attached to the material, as static electricity can affect the use of the material and therefore requires static elimination.

It has a discharge port 7 corresponding to the grounding tray 5, which is used to protect the internal structure and form a working space.

It is an anode electrostatic adsorption plate and is used to adsorb the cut fibers. Inclined chute 15: Located at the bottom of electrostatic adsorption plate 14, with the other side connected to grounding tray 5. It is made of non-metallic material with poor conductivity and is used to slide the adsorbed fibers onto the grounding tray 5.

[0023] Working Principle: This short fiber guiding and cutting device adopts a modular design, consisting of core components such as the outer shell 1, upper structure 2, and lower structure 3. Inside the outer shell 1, the upper structure 2 and lower structure 3 each perform their respective functions, working together to complete the entire process of fiber cutting, collection, and electrostatic treatment. During operation, bundled textile fibers enter the equipment from the feed inlet 6 through the guide tube 4. The guide tube 4 provides directional guidance for the fiber bundle, ensuring its stable delivery to the upper structure 2. The servo motor 9 in the upper structure 2 drives the cutting wheel 8 to rotate at high speed. The cutting wheel 8 consists of a structural disc 10, a structural ring 11, and cutting blades 12. Multiple sets of cutting blades 12 are evenly distributed on the connecting column 13, forming a high-efficiency cutting interface. By adjusting the speed of the servo motor 9 and controlling the feed speed of the feed inlet 6, the fiber cutting length can be precisely controlled to meet different production needs. When the fiber bundle passes through the high-speed rotating cutting wheel 8, the cutting blades 12 quickly cut it into short fibers of a specific length. The cut fiber filaments continue to move under inertia, at which point the lower structure 3 begins to function. The electrostatic adsorption plate 14 in the lower structure 3 generates an electrostatic field after being energized. Utilizing the principle of cation electrostatic adsorption, the cut fiber filaments are attracted to the plate surface due to their charge. As the fibers accumulate and reach a certain weight, they slide down the inclined chute 15 below the electrostatic adsorption plate 14 under the influence of gravity. The inclined chute 15 is made of a non-metallic material with poor conductivity to prevent fiber retention due to electrostatic adsorption, ensuring the fibers slide smoothly onto the grounding tray 5. The grounding tray 5 is made of a highly conductive metallic material, with a conductive wire connected to the ground at its bottom. When the charged fiber contacts the grounding tray 5, the charge on it is quickly conducted to the ground through the conductive wire, eliminating static electricity. The eliminated fiber filaments are then output from the discharge port 7. This design effectively avoids the impact of static electricity on the subsequent use of the fibers, prevents fiber scattering, reduces potential hazards to the human body, and ensures the occupational health and safety of operators. The entire device achieves an integrated process from fiber input, precise cutting, efficient collection to static electricity elimination through the orderly cooperation of its various components. It is convenient to operate, stable and reliable, and has significant practicality and application value in the field of short fiber processing.
