Description

Technical Field

[0001] This application relates to the technical field of textile machinery, and in particular to a feeding device for nonwoven fabric processing. Background Technology

[0002] Nonwoven fabrics, as a widely used nonwoven material, have important applications in many fields such as medical, hygiene, and industry. With the continuous growth of market demand for nonwoven fabric products and the increasing requirements for quality, the production process of nonwoven fabrics is also being continuously improved and optimized. As a key starting step in the nonwoven fabric production process, the stability, efficiency, and precision of the feeding process have a crucial impact on the subsequent processing quality and production efficiency of the entire nonwoven fabric.

[0003] Traditional nonwoven fabric processing feeding devices often suffer from several shortcomings. Firstly, many devices lack a rational modular design, resulting in low functional integration between different parts. During the feeding process, the connections between temporary storage, conveying, and quantitative distribution of raw materials are not smooth enough, easily leading to supply interruptions, conveying blockages, or uneven distribution. This disrupts the rhythm of subsequent nonwoven fabric production processes, affecting production continuity and reducing efficiency. Secondly, insufficient consideration is given to the cleaning and filtration of raw materials and the maintenance of the device itself. Impurities carried in the raw materials are difficult to remove effectively, negatively impacting the quality of the nonwoven fabric, such as causing appearance defects and reduced strength. Furthermore, when the device malfunctions or requires maintenance, the limitations of the structural design make repairs difficult, consuming significant time and manpower, increasing production maintenance costs, and further affecting the stability and continuity of production. Utility Model Content

[0004] In view of the above-mentioned prior art, in order to solve the problems of poor continuity of raw material supply, inaccurate distribution, poor removal of raw material impurities, and difficulty in equipment inspection and maintenance caused by unreasonable unit design of traditional nonwoven fabric processing feeding devices, which in turn affect the production efficiency and product quality of nonwoven fabrics, this application provides a feeding device for nonwoven fabric processing.

[0005] This application provides a feeding device for nonwoven fabric processing, which adopts the following technical solution: A feeding device for nonwoven fabric processing includes multiple independent boxes stacked vertically, each box integrating a functional unit, and adjacent boxes being detachably connected via connectors. The multiple boxes are respectively a feeding box, a filtering box, a temporary storage box, a conveying box, and a metering box. The feeding box integrates a feeding unit for receiving external nonwoven fabric raw materials; the filtering box integrates a filtration and cleaning unit for removing large particles, dust, and light impurities from the raw materials; the temporary storage box integrates a raw material temporary storage unit for temporarily storing the cleaned raw materials; the conveying box integrates a conveying drive unit for uniformly and smoothly conveying the raw materials; and the metering box integrates a metering distribution unit for precisely controlling the raw material supply according to processing requirements. The feeding box is located at the top layer, the filtering box is located below the feeding box, and the feeding unit… The discharge end of the raw material storage unit is connected to the inlet end of the filter cleaning unit; the temporary storage box is located below the filter box, and the inlet end of the raw material storage unit is connected to the discharge end of the filter cleaning unit; the conveying box is located below the temporary storage box, and the inlet end of the conveying drive unit is connected to the discharge end of the raw material storage unit; the quantitative box is located below the conveying box and is set at the bottom layer, the discharge end of the conveying unit is connected to the inlet end of the quantitative distribution unit, and the discharge end of the quantitative distribution unit is connected to the inlet of the external nonwoven fabric subsequent processing equipment.

[0006] By adopting the above technical solution, the modular design of "independent cabinets + functional integration" breaks through the limitations of the traditional feeding device's dispersed functions. The five core processes—feeding, filtering, temporary storage, conveying, and quantitative feeding—are integrated into corresponding cabinets, which are stacked vertically. This not only significantly saves horizontal installation space and adapts to the layout of nonwoven fabric production workshops of different sizes, but also ensures that each process operates independently and efficiently, avoiding the problem of chaotic raw material handling caused by overlapping functions. Raw materials enter from the top feeding cabinet, pass through the functional processing of the lower cabinets, and are finally accurately conveyed to the downstream processing equipment, forming a continuous top-down feeding process. This effectively avoids supply interruptions and jams caused by chaotic raw material conveying paths in traditional devices, ensuring the continuity of nonwoven fabric production. At the same time, each unit performs its specific function, forming a complete process control from raw material reception and impurity removal to quantitative supply, laying the foundation for improving the quality of nonwoven fabric products.

[0007] Preferably, the feeding box is a cylindrical shell with an open top, and a dust cover is detachably installed at the opening. An inclined guide plate is fixedly installed inside the feeding box, and the bottom end of the guide plate extends to the discharge end of the feeding unit.

[0008] By adopting the above technical solutions, the cylindrical shell structure, compared to the traditional square shell, reduces material residue on the inner wall of the chamber during material input, thus lowering cleaning difficulty. The top opening design facilitates rapid input of external materials, while the removable dust cover can be closed promptly after material input, effectively preventing dust, lint, and other impurities in the workshop from entering the feeding chamber and contaminating the raw materials, ensuring the initial cleanliness of the materials and preventing impurities from entering subsequent processes and affecting the quality of the nonwoven fabric. Simultaneously, the inclined guide plate inside the chamber guides the input raw materials, guiding them smoothly down the inclined surface to the discharge end of the feeding unit, avoiding accumulation and clumping caused by direct material fall. This ensures that the raw materials enter the downstream filter chamber evenly, guaranteeing the efficient operation of the subsequent filtration and cleaning units.

[0009] Preferably, a first observation window is provided on each of the opposite side walls of the feeding box, and an installation rod is provided on both sides of the feeding box near the two first observation windows. The two ends of the installation rod are fixedly connected to the side wall of the feeding box, and the installation rod does not abut against the first observation window. A grating is fixedly installed on both installation rods.

[0010] By adopting the above technical solution and setting up a first observation window, staff can view the amount of raw materials in the feeding box, the conveying status, and whether there is any blockage in real time. This allows them to understand the internal situation without opening the box, reducing the risk of impurities entering due to frequent opening and improving the efficiency of monitoring the device's operating status. The mounting rods provide a stable mounting platform for the gratings, and the mounting rods do not abut against the first observation window to avoid obstructing the view. The gratings on the two mounting rods form a cross-sensing optical path. When the external raw material conveying rate is too fast, or when the downstream filter box experiences a temporary decrease in processing efficiency leading to raw material accumulation at the feeding box outlet, the accumulated raw material will block the grating's sensing optical path. At this time, the grating will immediately send a warning signal to the device's control system. After receiving the signal, the control system can automatically adjust the speed of the external raw material conveying equipment, reduce the feeding amount, or suspend the feeding when the accumulation is serious. This effectively prevents the excessive accumulation of raw materials from squeezing and damaging the inner wall and internal components of the feeding box. At the same time, it avoids the formation of clumps due to long-term accumulation and compaction of raw materials, ensuring that the raw materials remain in a loose state when entering the filter box. This improves the removal effect of impurities by the filter cleaning unit, extends the service life of the feeding box and internal components, and ensures the stable operation of the feeding process.

[0011] Preferably, both the filter box and the feed box are provided with inspection ports, and the inspection ports are provided with sealing covers.

[0012] By adopting the above technical solution, an inspection port is set on the filter box, which facilitates the staff to regularly maintain the internal filter cleaning unit, such as replacing aging coarse filter components, cleaning dust attached to fine filter components, and checking the adsorption effect of electrostatic adsorption components, to ensure that the filter cleaning unit always maintains good impurity removal capabilities; while the inspection port on the feed box facilitates the inspection and maintenance of internal guide plates, feed units and other components, such as adjusting the tilt angle of the guide plates and repairing conveying faults in the feed unit.

[0013] Preferably, the temporary storage box is a double-layer stainless steel insulated shell, with a rock wool insulation layer filling the interlayer.

[0014] By adopting the above technical solution, the double-layer stainless steel shell possesses high strength and corrosion resistance, effectively protecting the raw material storage unit inside the temporary storage box from damage caused by external collisions and compression. Simultaneously, the smooth surface of the stainless steel material does not easily absorb fibrous impurities from the raw materials, facilitating subsequent cleaning. The rock wool insulation layer filling the shell interlayer has excellent thermal insulation performance, maintaining a relatively stable temperature environment inside the temporary storage box and preventing excessive fluctuations in workshop ambient temperature from affecting the physical properties of the raw materials.

[0015] Preferably, an inspection door is provided on the side wall of the temporary storage box, and a second observation window is provided on the inspection door.

[0016] By adopting the above technical solution, when problems such as raw material blockage or wear and tear of raw material storage unit components occur in the temporary storage box, staff do not need to disassemble the stacked boxes. They can simply open the inspection door to directly reach inside the box for troubleshooting and repair, significantly reducing downtime for maintenance and minimizing interference with the overall production process. The second observation window on the inspection door complements the first observation window of the feeding box. Staff can use the second observation window to view the amount of raw material in the temporary storage box in real time, whether there is any accumulation or clumping of raw material, and the condition of the insulation layer. This allows for timely detection and handling of potential problems, preventing minor faults from developing into major malfunctions and causing prolonged downtime.

[0017] Preferably, an installation box is provided on the outer side wall of the conveying box. The installation box is a rectangular shell and is used to accommodate the transmission components of the conveying drive unit.

[0018] By adopting the above technical solution, the rectangular housing mounting box has a regular structure, facilitating close fitting and fixation to the outer wall of the conveying box. Furthermore, the internal space can be precisely designed according to the dimensions of the transmission components, ensuring stable accommodation of these components. The transmission components of the conveying drive unit (such as gears, chains, and drive shafts) are the core structure for achieving "uniform and smooth conveying" of raw materials, and their operating status directly affects the continuity of feeding. The mounting box, as a dedicated containment space, effectively isolates a large amount of dust, fiber debris, oil, and other impurities from the nonwoven fabric processing environment, preventing impurities from adhering to the surface of the transmission components and causing jamming, wear, or corrosion, thus ensuring the flexible operation of the transmission components. Simultaneously, the mounting box reduces the impact of external collisions and vibrations on the transmission components, lowering the risk of failure due to accidental damage and extending the service life of the transmission components. In addition, a small inspection door can be installed on the mounting box, facilitating regular lubrication, inspection, and maintenance of the internal transmission components by staff, further improving the operational stability of the conveying drive unit and ensuring that raw materials are continuously and uniformly conveyed to the metering box.

[0019] Preferably, the quantitative box is equipped with a cleaning component for removing fiber deposits.

[0020] By adopting the above technical solution, during the conveying and temporary storage of nonwoven fabric raw materials, some fibers are prone to detaching and accumulating on the inner wall of the metering box, the feed inlet of the metering distribution unit, and the internal channels. If the accumulation is not cleaned for a long time, it will narrow the feed channel of the metering distribution unit, affecting the raw material conveying rate and even causing blockages. At the same time, it may also lead to a decrease in the control accuracy of the metering distribution unit in terms of raw material supply, resulting in problems of over- or under-supply, which in turn affects the quality of downstream nonwoven fabric processing. By setting up cleaning components, a clean environment can be effectively maintained inside the metering box, ensuring that the metering distribution unit is always in good working condition, guaranteeing accurate control of raw material supply, avoiding malfunctions caused by fiber accumulation, reducing raw material waste, and improving the overall operating efficiency of the device.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By adopting a modular design of "independent box + functional integration," the traditional feeding device breaks through the limitations of its dispersed functions. The five core links of feeding, filtering, temporary storage, conveying, and quantitative feeding are integrated into corresponding boxes. The boxes are stacked vertically, which not only saves a lot of horizontal installation space and adapts to the layout of nonwoven fabric production workshops of different sizes, but also ensures that each link operates independently and efficiently through clear functional zoning, avoiding the problem of chaotic raw material processing caused by functional overlap. The raw material enters from the top feeding box, passes through the functional processing of each box below, and is finally accurately conveyed to the downstream processing equipment, forming a continuous feeding process from top to bottom. This effectively avoids the problems of supply interruption and jamming caused by the chaotic raw material conveying path in traditional devices, ensuring the continuity of nonwoven fabric production. At the same time, each unit performs its own function, forming a full-process control from raw material receiving and impurity removal to quantitative supply, laying the foundation for improving the quality of nonwoven fabric products. 2. By setting up a first observation window, staff can view the amount of raw materials in the feed box, the conveying status, and whether there is any blockage in real time. This allows them to monitor the internal situation without opening the box, reducing the risk of impurities entering due to frequent opening and improving the efficiency of monitoring the device's operating status. The mounting rods provide a stable mounting surface for the gratings, and do not abut against the first observation window to avoid obstructing the view. The gratings on the two mounting rods form a cross-sensing light path. When the external raw material conveying rate is too fast, or when the downstream filter box temporarily reduces its processing efficiency, causing leakage at the feed box outlet... When raw materials accumulate, they can block the light path of the grating. In this case, the grating will immediately send a warning signal to the control system of the device. After receiving the signal, the control system can automatically adjust the speed of the external raw material conveying equipment, reduce the feeding amount, or stop feeding when the accumulation is severe. This effectively prevents the excessive accumulation of raw materials from squeezing and damaging the inner wall and internal components of the feeding box. At the same time, it avoids the formation of clumps due to long-term accumulation and compaction of raw materials, ensuring that the raw materials remain loose when entering the filter box. This improves the removal effect of the filter cleaning unit on impurities, extends the service life of the feeding box and internal components, and ensures the stable operation of the feeding process. 3. During the conveying and temporary storage of nonwoven fabric raw materials, some fibers are prone to detaching and accumulating on the inner wall of the metering box, the feed inlet of the metering distribution unit, and the internal channels. If the accumulation is not cleaned for a long time, it will narrow the feed channel of the metering distribution unit, affecting the raw material conveying rate and even causing blockages. It may also lead to a decrease in the accuracy of the metering distribution unit's control over the raw material supply, resulting in overfeeding or underfeeding, which in turn affects the quality of downstream nonwoven fabric processing. By incorporating cleaning components, a clean environment can be effectively maintained inside the metering box, ensuring that the metering distribution unit is always in good working condition, guaranteeing accurate control of the raw material supply, avoiding malfunctions caused by fiber accumulation, reducing raw material waste, and improving the overall operating efficiency of the equipment.

[0024] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0025] This application discloses a feeding device for nonwoven fabric processing.

[0026] Reference Figure 1 and Figure 2 A feeding device for nonwoven fabric processing includes multiple independent boxes 1 arranged vertically, and adjacent boxes 1 are detachably connected by bolts; the multiple boxes 1 are respectively integrated with functional units, namely feeding box 11, filtering box 12, temporary storage box 13, conveying box 14 and metering box 15.

[0027] The feeding box 11 is located at the top layer and integrates a feeding unit for receiving external non-woven fabric raw materials. The top of the feeding box 11 is cylindrical with an opening, and a dust cover 111 is provided at the opening for sealing. First observation windows 112 are provided on opposite side walls of the outer side of the feeding box 11. Mounting rods 113 are provided on the side walls of the feeding box 11 near the two first observation windows 112, and gratings 114 are fixedly mounted on both mounting rods 113. If the external raw material conveying rate is too fast, or if raw material accumulates at the outlet of the feeding box 11 due to temporary storage by the downstream filtration unit, the accumulated raw material will block the sensing light path of the grating 114. The grating 114 will send a warning signal to the control system, automatically reducing the external raw material conveying rate or suspending the feeding, to prevent excessive accumulation of raw material from damaging the feeding box 11, or from affecting the subsequent filtration effect due to material compaction and agglomeration, thus extending the service life of the feeding box 11 and its internal components.

[0028] The filter box 12 is located below the feed box 11. The filter box 12 integrates a filter cleaning unit, which includes a coarse filter assembly, a fine filter assembly, and an electrostatic adsorption assembly. The coarse filter assembly, the fine filter assembly, and the electrostatic adsorption assembly are fixed in sequence along the material flow square inside the filter box 12. A guide plate is inclinedly arranged inside the feed box 11. The bottom end of the guide plate extends to the discharge end of the feed unit to guide the raw material into the filter box 12.

[0029] Both the filter housing 12 and the feed housing 11 have inspection ports 2 on their side walls, and each inspection port 2 is hinged with a sealing cover 3 for closing. When the guide plate in the feed housing 11 shifts position, the feed unit malfunctions, or the coarse filter assembly in the filter housing 12 becomes clogged, the fine filter assembly ages, or the electrostatic adsorption assembly's adsorption capacity decreases, workers do not need to disassemble the stacked housing 1 structure. They only need to open the hinged sealing cover 3 to directly access the inside of the housing 1 through the inspection port 2 to inspect, adjust, clean, or replace components. Compared to the traditional method of requiring complete disassembly for maintenance, this significantly reduces maintenance steps and operation time, improving maintenance efficiency.

[0030] The temporary storage box 13 is located below the filter box 12. The temporary storage box 13 integrates a raw material storage unit. The temporary storage box 13 is a double-layered insulated shell with a rock wool insulation layer between the two layers. The discharge end of the filter cleaning unit is connected to the feed end of the raw material storage unit.

[0031] The temporary storage box 13 is equipped with an inspection door 131 on its side wall, and a second observation window 132 is provided on the inspection door 131. When problems such as raw material blockage or component wear (such as insulation layer damage) occur in the temporary storage box 13, it is not necessary to disassemble the stacked boxes 1. The inspection door 131 can be opened to directly reach inside for inspection and repair, which greatly shortens downtime maintenance time and reduces interference with the overall production process.

[0032] A liquid level sensor 133 is also installed inside the temporary storage tank 13. The liquid level sensor 133 can monitor the actual height of the raw materials in the temporary storage tank 13 in real time and transmit the data to the control system. When the amount of raw materials is lower than the preset threshold, the system can automatically increase the raw material conveying rate of the upstream filtration unit to avoid the downstream conveying unit from interrupting the material supply due to material shortage. When the amount of raw materials is higher than the threshold, the upstream material supply can be slowed down to prevent the raw materials from being excessively piled up and compacted.

[0033] The conveying box 14 is located below the temporary storage box 13. The conveying box 14 integrates a drive unit, which is used to convey the raw materials at a uniform speed without jamming. An installation box 141 is provided on the outer wall of the conveying box 14. The installation box 141 is a rectangular shell and also has an inspection door 131. The installation box 141 provides dedicated housing and protection space for the transmission components of the conveying drive unit. The transmission components of the conveying drive unit are the core structure for achieving "uniform speed and jam-free conveying" of the raw materials, and their operating status directly affects the continuity of feeding. The installation box 141, as a dedicated housing space, effectively isolates dust, fiber debris, oil, and other impurities in the nonwoven fabric processing environment, preventing impurities from adhering to the surface of the transmission components and causing jamming, wear, or corrosion. At the same time, it reduces the impact of external collisions and vibrations on the transmission components, lowers the risk of failure caused by accidental damage, extends the service life of the transmission components, and ensures stable raw material conveying function.

[0034] The quantitative dispensing unit 15 integrates a quantitative dispensing unit, which is used to precisely control the raw material supply according to processing requirements. The quantitative dispensing unit 15 also includes a cleaning component 151 for removing fiber buildup. As a core functional component, the quantitative dispensing unit can precisely control the output of raw materials based on the actual production rhythm and raw material demand of subsequent nonwoven fabric processing equipment. This prevents excessive raw material supply from overloading downstream equipment, avoiding problems such as raw material accumulation and processing delays, and thus preventing raw material waste.

[0035] When the equipment is in use, the external non-woven fabric raw material is first fed into the top opening of the feeding box 11, and the dust cover 111 is closed to isolate external dust pollution. Under the guidance of the inclined guide plate, the raw material smoothly enters the feeding unit and is conveyed to the filter box 12 below. Inside the filter box 12, the raw material passes through the coarse filter component to remove large particulate impurities, the fine filter component to filter dust, and the electrostatic adsorption component to remove light impurities, completing a comprehensive cleaning. The cleaned raw material then enters the temporary storage box 13. The double-layer stainless steel shell and rock wool insulation layer can maintain a suitable storage environment for the raw material. The liquid level sensor 133 monitors the amount of raw material in real time, and the upstream feeding rate is dynamically adjusted by the control system to ensure a stable temporary storage volume. When the conveying unit is started, the raw materials in the temporary storage box are conveyed to the conveying box 14. The outer side of the box 141 protects the transmission components from impurities and external forces, ensuring that the raw materials are conveyed at a uniform speed and without jamming to the bottom quantitative box 15. The quantitative distribution unit accurately controls the output of raw materials according to the needs of downstream processing equipment. At the same time, the cleaning component 151 regularly removes fiber accumulation in the box. Finally, the raw materials that meet the requirements are stably conveyed to the feed port of the external nonwoven fabric subsequent processing equipment through the discharge end of the quantitative distribution unit, realizing the continuous, efficient and precise operation of the entire feeding process.

[0036] The implementation principle of this application embodiment is as follows: Based on the modular design concept, the five key functions of receiving, cleaning, temporary storage, conveying, and quantitative feeding in the non-woven fabric feeding process are integrated into independent boxes 1. Each box 1 is vertically stacked via detachable connectors, forming a compact and functionally distinct hierarchical feeding system. During raw material processing, the feeding box 11 first prevents contamination with a dust cover 111 and controls the rate with a grating 114, ensuring stable raw material entry. Then, impurities are removed layer by layer by the three-stage cleaning components of the filter box 12. Finally, the temporary storage box 13 is used to preserve the raw materials. The temperature structure protects the environment, and the liquid level sensor 133 regulates supply and demand, providing a stable reserve for subsequent conveying. Then, the conveying box 14, through the installation of the box 141, protects the transmission components, ensuring that the raw materials are conveyed at a uniform speed without jamming. Finally, the quantitative box 15 accurately controls the quantity through the quantitative distribution unit, and the cleaning component 151 removes accumulated materials, realizing the supply of raw materials on demand. At the same time, the design of the inspection door 131 and observation window of each box 1 reduces the difficulty of maintenance. The whole system solves many problems of traditional feeding devices through functional modularization, process hierarchy and intelligent control, ensuring that the feeding process is continuous, efficient and accurate.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
