Description

Technical Field

[0001] This invention belongs to the field of conductive ring technology, specifically relating to a spiral collection device, system and method for fibers after conductive ring shearing, which can be widely used in manufacturing, textile, papermaking, agriculture, environmental protection, food, renewable resource recycling, medical and hygiene materials and other industries. Background Technology

[0002] Currently, conductive ring fiber cleaning equipment generally adopts an open-chassis collection method, where the cut fibers are directly scattered and piled up inside the chassis. This method has the following problems: First, low space utilization: the fibers are piled up in a loose and disordered state, resulting in a small effective collection volume and requiring frequent shutdowns for cleaning; second, low cleaning efficiency: the fibers are tangled and scattered, making manual cleaning prone to leaving residues and posing a risk of secondary scattering; third, automation obstacles: disordered fibers are difficult to integrate with automated conveying or compression devices, restricting continuous operation.

[0003] Therefore, existing solutions lack methods to improve space utilization through structured collection (such as directional compression and orderly conveying), and there is an urgent need for an innovative device that can achieve efficient, continuous, and closed collection of fibers. Summary of the Invention

[0004] This invention provides a spiral collection device, system, and method for fibers cut from conductive rings. The spiral force enables collection functions such as conveying and compaction, achieving orderly and efficient collection and cleaning of fibers cut off during conductive ring production, significantly improving production capacity and reducing costs.

[0005] This invention provides the following technical solutions: A spiral fiber collection device, comprising: The collection chamber is equipped with an inlet and an outlet, through which waste fibers cut off from the conductive ring are received; A spiral mechanism, disposed within the collection chamber, is used to quantitatively and continuously convey and simultaneously pre-compress the waste fibers before conveying them to the discharge port; The material collection device has its inlet sealed to the outlet, and is used to receive the waste fibers continuously pushed in by the screw mechanism, and to achieve secondary compaction of the waste fibers by continuously pushing in the waste fibers using the screw mechanism.

[0006] Preferably, the spiral mechanism is configured such that the waste fibers are subjected to gradually increasing mechanical compressive force along the conveying path.

[0007] Preferably, the increasing mechanical extrusion pressure is achieved through at least one of the following methods: a) The pitch of the screw mechanism gradually decreases along the conveying direction; b) The diameter of the screw shaft of the screw mechanism gradually increases along the conveying direction; c) The cross-sectional area of ​​the outlet channel of the screw mechanism gradually decreases along the conveying direction.

[0008] Preferably, it further includes a blowing and sucking assist system, which includes at least one of the following units: An air blowing unit is used to blow gas into the bottom area of ​​the collection chamber to fluidize the waste fibers so that they can be grasped and transported by the spiral mechanism. The suction unit is used to draw gas from the bottom region of the collection chamber so that some of the debris in the waste fiber is removed.

[0009] Preferably, the blowing unit and / or the suction unit operate in a pulse mode to generate intermittent pulsed airflow, the pulse frequency of which is configured in relation to the operating speed of the spiral mechanism; And / or, the spiral fiber collection device further includes a filter screen disposed at the bottom of the collection chamber and separating the blowing unit and the suction unit from the main cavity of the collection chamber, for preventing waste fibers from entering the suction unit while allowing airflow from the blowing unit to pass through; And / or, the negative pressure of the suction unit is provided by a vacuum cleaner.

[0010] Preferably, the inner wall of the collection cavity is provided with an anti-adhesion coating and / or equipped with a vibrator to prevent waste fibers from adhering and accumulating on the inner wall of the cavity.

[0011] Preferably, the collecting device is a replaceable flexible or semi-rigid container that can be quickly disassembled, and its inlet is sealed to the outlet through a sealing connection structure.

[0012] Preferably, it also includes an intelligent control system, which is configured to: control the start-up, shutdown and rotation speed of the screw mechanism according to a preset time interval or the material level signal of the collecting cavity; and monitor the load current of the drive motor of the screw mechanism, and when the current continuously exceeds a set threshold, determine that the collecting device is full or blocked, and trigger an alarm or shutdown.

[0013] The present invention also provides a fiber collection system comprising at least two spiral fiber collection devices as described in any embodiment of the present invention, wherein the at least two devices are connected in parallel or in series via a centralized conveying pipeline and are managed by a central controller.

[0014] The present invention also provides a fiber collection method using the spiral fiber collection device described in any embodiment of the present invention, comprising the following steps: Dynamic collection steps: Waste fibers cut off by the conductive ring are continuously or intermittently fed into the collection chamber; Integrated conveying and compression steps: Through the screw mechanism, the waste fibers are conveyed from the collection chamber to the collection device, and the initial compression and compaction of the waste fibers are completed simultaneously. Sealing and sealing steps: The waste fibers that have been initially compressed and compacted are directly pushed into the collection device for a second compression and compaction process before sealing.

[0015] Compared with the prior art, the present invention has one or more of the following significant advantages: In terms of improving space utilization: the fiber is changed from a "loosely packed state" to a "densely compressed state". Therefore, by adopting dynamic compression collection technology, the fiber collection density is increased by more than 60% through the synergistic action of the screw conveyor mechanism and the collection device, and the volume occupied is significantly reduced, which completely solves the problem of loose fiber accumulation in the traditional machine box. In particular, the collection volume is increased by more than 2-3 times under the same volume. In terms of economic benefits: The effectively extended cleaning cycle brings significant economic benefits. For example, the original plan required three daily shutdowns for cleaning, each taking 0.5 hours, resulting in a daily loss of 1.5 hours. Now, cleaning is only required once every three days or even longer, averaging less than 0.17 hours of loss per day. Production efficiency is significantly improved, for example, to (1-0.17) / 1=83%. Therefore, it significantly reduces equipment downtime for maintenance and improves continuous operation capability. Furthermore, considering the costs of manual cleaning, the frequency of manual cleaning can be reduced by more than 60%, saving even more costs. In terms of automation and environmental protection: The innovative continuous compression mechanism allows the fibers to be stored in high-density blocks, making the compressed fibers easier to transport and process. In particular, the compressed fiber blocks can be easily grasped, weighed, and transferred by robotic arms, just like "bricks," laying the foundation for future "unmanned factories" and reducing overall operation and maintenance costs by 40%-50%. Moreover, since the collection work is completed in a closed chamber, the collection process is completely sealed, eliminating secondary pollution and significantly contributing to the improvement of the conductive ring production environment (reduction of PM2.5 / PM10 index). This effectively protects production workers and conductive ring products from the impact of flying waste fibers. Attached Figure Description

Detailed Implementation

[0017] The implementation of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0019] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] It should be noted that various aspects of embodiments within the scope of the appended claims are described below. It will be apparent that the aspects described herein can be embodied in a wide variety of forms, and any particular structure and / or function described herein is merely illustrative. Based on this invention, those skilled in the art will understand that one aspect described herein can be implemented independently of any other aspect, and two or more of these aspects can be combined in various ways. For example, any number and aspects set forth herein can be used to implement the device and / or practice the method. Additionally, this device and / or method can be implemented using structures and / or functionalities other than one or more of the aspects set forth herein.

[0021] It should also be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0022] Additionally, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that practice can be carried out without these specific details.

[0023] In the existing technology, the problems faced by conductive ring fiber cleaning equipment (low space utilization, high cleaning frequency, and automation obstacles) are not isolated. The root cause lies in the insufficient understanding of the physical characteristics of "fiber" as the object to be processed, which leads to systemic design flaws.

[0024] Cognitive level: Ignoring the material properties of fibers. Fibers are lightweight, fluffy, easily tangled, and prone to flying. Traditional open-style scattered collection methods are essentially a passive, static containment strategy that fails to actively intervene in and change the stacking pattern of fibers.

[0025] Design-wise: A lack of "form management" thinking. Fibers are treated as ordinary debris, merely provided with a container, without any mechanism designed to "reshape" them (such as compressing or orienting) during collection. This results in the fibers remaining in their most natural, fluffy state, which is the core of all the problems.

[0026] At the system level: Collection and subsequent processing are disconnected. The collection unit (chassis) and subsequent processing (such as transfer, compression and packaging) are separate. The disorderly piled fibers cannot be efficiently and cleanly removed by automated equipment (such as conveyor belts and packaging machines), forming a "bottleneck" in the automated process.

[0027] Based on this, the present invention proposes a novel concept for collecting and cleaning scattered fiber materials sheared during the production of conductive rings: the concepts of "dynamic compression" and "orderly conveying" are integrated into the fiber "collection process" itself in advance, rather than being processed afterward.

[0028] On the one hand, there is a shift in technological thinking: from "passive accommodation" to "proactive management"; from "static accumulation" to "dynamic circulation".

[0029] Secondly, the core idea is that from the moment the fiber enters the collection container, its fluffy and disordered state is forcibly changed by mechanical force, so that it is continuously compressed during the transportation process and enters the final storage unit in a high-density and regular form.

[0030] In three aspects, the technical approach is as follows: the "spiral drive mechanism" is adopted as the core means to realize this concept. The spiral mechanism has the dual functions of "conveying" and "preliminary compression", which can realize the "dynamic" and "orderly" fiber collection and cleaning.

[0031] It should be noted that this invention is not an improvement on a single component, but a systemic solution in which all components work collaboratively around a core concept: First, the core actuator (spiral mechanism) achieves "dynamic compression and collection." As the spiral blades rotate, they not only push the fibers forward, but the space between the blades naturally creates initial compression of the fibers. Based on this, secondary compression and collection are completed at the outlet using relevant components (such as a conical outlet, pressure rollers, and collection bags), ultimately forming high-density blocky fibers. It should be noted that this invention differs from the traditional "collect first, then compress" approach. Instead, it utilizes the spiral mechanism to organically combine "dynamic initial collection" with "fixed-point final compaction," thus forming a completely new technical solution for waste fiber collection.

[0032] Secondly, auxiliary components (back-blowing mechanism + suction mechanism) solve problems such as "bridging" and "entanglement" that may occur during fiber conveying, ensuring "continuous" operation. The back-blowing mechanism introduces airflow from the bottom, breaking the electrostatic adsorption of the fibers, making them fluffy and easy for the spiral to grasp; the suction mechanism generates negative pressure at the outlet, forming airflow traction, assisting the fibers to smoothly enter the spiral drive mechanism. The alternating blowing and suction can be a working mechanism to ensure that the fibers enter the spiral drive mechanism in an orderly and controllable manner to complete the initial compression and collection.

[0033] Third, the sealed, integrated design (cavity + collection mechanism) eliminates "secondary pollution" and is compatible with "automation." The entire collection path, from the inlet to the dust collection bag, is completely sealed, preventing fibers from flying around. The spiral outlet directly connects to the dust collection bag, allowing the initially compressed fibers to be directly fed into the bag for orderly secondary compression and collection. Finally, the fibers are directly transferred as semi-finished products through bagging, achieving integration of collection and packaging.

[0034] Fourth, the filter and separation function is designed with a filter screen at the bottom of the cavity to separate the fine debris carried out in the airflow circulation, preventing it from entering the back-blowing mechanism or the suction mechanism and causing blockage, thus ensuring the long-term stable operation of the air circuit system.

[0035] In summary, the technical concept of this invention is an interconnected organic whole: a spiral mechanism for dynamic compression and conveying serves as the core, while air blowing and suction components provide auxiliary support, achieving a fully enclosed integrated collection and cleaning process. This collectively solves the fundamental defects of existing technologies, such as static, disorderly accumulation and lint pollution. It should be noted that before the improvement, each conductive ring production station required a vacuum cleaner to remove fiber lint, and the vacuum cleaner needed to be cleaned multiple times a day to prevent clogging. However, after the improvement, one vacuum cleaner can provide suction capacity for the collection and cleaning equipment at at least five stations, and the vacuum cleaner does not need frequent cleaning (it can be cleaned only once every five days or even longer), reducing the likelihood of fiber lint clogging during production. Therefore, after the improvement, all fiber material cut from the conductive rings can be collected in a closed collection and cleaning system, eliminating fiber lint pollution in the production workshop and workstations, providing a good environment for conductive ring production. Furthermore, the collection equipment no longer requires frequent shutdowns for cleaning and maintenance, significantly improving conductive ring production capacity.

[0036] The invention will now be illustrated by examples.

[0037] Example 1: Dynamic Collection and Compaction Spiral Fiber Collection Device refer to Figures 1 to 11 This invention provides a spiral fiber collection device, comprising: Collection chamber 1: Made of 304 stainless steel, with a volume of 0.15m³; the top is equipped with a hinged cover plate 104, and the cover plate is provided with a feed inlet 102. The inner wall is mirror polished and sprayed with a Teflon anti-stick coating; the side wall of collection chamber 1 is provided with a discharge port 103. Screw mechanism 2: Adopts a conventional screw design with equal pitch (150mm) and equal shaft diameter (50mm), and blade outer diameter of 160mm. Its drive motor 21 is a 1.1kW three-phase motor, with speed controlled by a frequency converter (range 5-40rpm). Screw mechanism 2 is horizontally installed at the bottom of the collecting chamber 1, with its discharge end extending to the discharge port 103. Material collecting device 3: installed at the discharge port 103, wherein the material collecting device 3 includes a short cylindrical pipe (see Figure 1 (Illustrative image) and a collection bag (not shown in the figure). The diameter of the straight cylindrical short pipe is 160mm. The straight cylindrical short pipe is installed on the discharge port 103 through a flange. The collection bag is a 400L polyester woven bag. The bag opening is connected to the straight cylindrical short pipe through a pneumatic sealing ring structure. After air is introduced, the sealing ring expands and presses the bag opening to achieve a seal.

[0038] Working diagram: After waste fibers are fed into the feed inlet 102, the screw mechanism 2 runs at a constant speed of 15 rpm, steadily and quantitatively pushing the waste fibers to the discharge outlet 103. Then, after passing through the straight cylindrical short tube, the fibers enter the collection woven bag. Due to the continuous pushing of the screw, the fibers are initially compressed during the conveying process. After continuous accumulation in the bag, the fibers entering the bag later push the fibers that entered earlier, further realizing secondary dynamic compaction. This compresses the originally loose fibers from a loose state to a solid block state, realizing continuous closed collection. The cleaning cycle is extended from twice a day to once every three days or even longer.

[0039] In some examples, the collection chamber 1 can be configured as a funnel (see...). Figure 11 (Illustrative image) The funnel-shaped cavity can be a sealed chamber formed by the connection of the cavity body and the cavity cover through a hinge.

[0040] In some examples, drive transmission between the helical structure 2 and the drive motor 21 can be achieved via bearings (see [link]). Figure 7 (Illustrative diagram) That is, the motor is connected to the drive shaft of the screw mechanism 2 through a coupling or reducer to provide power.

[0041] Example 2: The collection device is equipped with a blowing and suction auxiliary system. The spiral fiber collection device also includes a blowing and suction auxiliary system, which enables effective fiber collection. This embodiment aims to illustrate the basic structure and working principle of the blowing and suction auxiliary system, demonstrating how this system effectively solves the problems of fiber caking at the bottom of the cavity and debris flying around.

[0042] like Figures 1 to 11 As illustrated, the blowing and inhalation assist system may include at least one of the following assist units: The suction unit 5 is used to draw gas from the bottom region of the collection chamber so that some of the debris in the waste fiber is drawn away. The air blowing unit 6 is used to blow gas into the bottom area of ​​the collection cavity to fluidize the waste fibers so that they can be grasped and transported by the spiral mechanism.

[0043] In practice, the suction unit 5 can be a vacuum cleaner that provides suction power through a pipe (the vacuum cleaner and pipe are not shown in the figure). In other words, because the fibers are effectively collected, and the collection process is carried out in a closed collection chamber 1 by the spiral mechanism 2 for compaction and transport, the device does not need to use suction to suck up the fibers for collection. Instead, the suction is only used to suck up the small debris fibers that fall off during the transport by the spiral mechanism 2. Therefore, the suction units 5 of multiple devices can share the suction power provided by one vacuum cleaner. For example, one vacuum cleaner can provide the corresponding suction power for the suction units 5 of 5-10 collection devices.

[0044] In some examples, the suction unit 5 can be powered by a negative pressure fan, such as a 0.55kW centrifugal fan. This fan can be fixed inside the frame 4 of the device or external to the device. When a vacuum cleaner is preferred to provide suction, it can be through an air intake located at the bottom of the collection chamber 1 (see [link]). Figure 1 The air vent at the bottom center of the cavity (as shown in the diagram) is connected to the corresponding air duct (not shown in the diagram).

[0045] In some examples, the air blowing unit 6 can be supplied with airflow by a positive pressure fan, such as a 0.25kW high-pressure fan, blowing airflow into the bottom of the chamber. This fan can be fixed to the lower part of the equipment frame 4 or external to the equipment, and the fan outlet is connected via a flexible hose to an annular equalizing pipe at the bottom of a collection chamber 1. In practice, the upper wall of the equalizing pipe can be evenly perforated with several small holes (e.g., mesh with a diameter of 3mm) to ensure that the airflow is evenly blown upwards into the bottom area of ​​the collection chamber 1.

[0046] In some examples, the intake unit 5 and / or the blowing unit 6 operate in a pulsed manner to generate intermittent pulsed airflow, the pulse frequency of which is configured in association with the operating speed of the spiral mechanism, thereby providing corresponding blowing and intake capabilities for the collection process and reducing the workload of the blowing unit, intake unit, etc.

[0047] In some examples, the spiral fiber collection device also includes at least one of the following mesh filter components: filter screen 9, perforated mesh plate 7, etc., wherein these filter components are disposed at the bottom of the collection chamber 1 to separate the blowing unit 6 and the suction unit 5 from the main cavity of the collection chamber 1, for example by installing the mounting components 8 (i.e., the mesh mounting plate 81 and the filter screen mounting plate 82) before the frame 4 and the collection chamber 1, to provide filtration and isolation capabilities for blowing and suction during the fiber collection process, which can make blowing more conducive to collection and effectively filter some fine debris, further extending the cleaning cycle and significantly reducing production cleaning time and cost.

[0048] In practice, the perforated mesh plate 7 is a microporous mesh plate made of sintered stainless steel. Its pore size can be set according to the fiber size; for example, if the pore size is set to 100 micrometers, the perforated mesh plate 7 can be designed as a V-shaped structure plate (see [reference]). Figure 5 , Figure 6 , Figure 8 (as shown in the diagram) The two sides of the structural plate are closely attached to the inner wall of the collection chamber 1. The bottom of the structural plate is set to be flat, which is used to form the conveying and compression space of the spiral mechanism 2 with the inner wall of the collection chamber 1. The sides and bottom of the structural plate can completely separate the lower space of the cavity where the blowing unit 6 and the suction unit 5 are located from the main cavity used to contain the fibers. And through the many mesh holes, it provides uniform air holes for the airflow of the blowing unit 6 and the suction unit 5.

[0049] In practice, the filter screen 9 can be a commercially available filter material, or a product with mesh and filter layer settings for filtering purposes such as fibers and air blowing and suction units. The filter screen 9 uses its own filter mesh and filter layer to prevent waste fibers from entering the suction unit 5 while allowing airflow from the air blowing unit 6 to pass through.

[0050] Work illustration: (1) Air blowing to prevent caking: When the equipment is running, the high-pressure vortex blower works and blows air into the bottom of the collection chamber 1. After the air passes through the filter screen 9, the perforated mesh plate 7, etc., the air becomes uniform and fine, which acts on the waste fibers accumulated in the collection chamber 1, making them "fluidized". This effectively breaks the clumps formed by the fibers due to static electricity and self-entanglement, making the fibers loose. This avoids the fiber "bridging" or caking at the bottom of the chamber from the root, which greatly facilitates the spiral blades of the spiral mechanism 2 to grab and transport the fibers. (2) Debris Removal: When the centrifugal fan is running, a negative pressure is formed in the bottom area of ​​the cavity. Fine debris and dust generated during the blowing airflow and fiber falling process will be drawn to the suction unit 5 (or suction port) at the bottom of the cavity under the guidance of the negative pressure. These debris can also be preliminarily filtered by the perforated mesh plate 7, filter screen 9, etc. and intercepted on one side of the main cavity, while clean air is discharged by the centrifugal fan after passing through the filter screen 9.

[0051] A synergistic effect is achieved through an auxiliary system of air intake and exhaust: the coordination of the air intake and exhaust units (which can operate continuously or intermittently, or with staggered operating times, etc.) creates a dynamic and controllable airflow at the bottom of the cavity. For example, air intake is responsible for "activating" the fibers to ensure smooth delivery; air intake is responsible for "purifying" the environment, removing micro-dust that affects the lifespan of the equipment and the working environment.

[0052] It should be noted that the perforated mesh plate 7 can play a preliminary filtering and isolation role, and the filter screen 9 can play a further isolation and protection role. On the one hand, it prevents fibers from clogging the air blowing holes or entering the air intake unit and damaging the fan. On the other hand, it also ensures that the airflow can pass through smoothly.

[0053] In summary, this embodiment, through its air blowing and suction assist system, can significantly improve equipment reliability and the cleanliness of the working environment.

[0054] Example 3: Intelligent Pulse Blowing and Suction Integrated Vacuum Cleaner Solution Based on Example 2, this embodiment further elaborates on the pulse working mode of the blowing and suction auxiliary system, the airflow correlation control, and the preferred scheme of using a vacuum cleaner as the suction unit, demonstrating the system's high efficiency and intelligence.

[0055] Pulsation operation of air blowing unit 6: The high-pressure vortex blower is retained, but a pulse valve controlled by a solenoid valve or a 110° two-part nozzle (e.g.) is added to its outlet duct. Figure 8 The nozzle structure parts shown in the blowing unit 6 and other components can be controlled by the main controller of the device (not shown in the figure) to achieve an intermittent pulsed working mode.

[0056] Replacement and integration of the suction unit: The dedicated centrifugal fan is replaced with a high-powered industrial-grade vacuum cleaner (not shown in the figure) to provide suction for suction unit 5. The vacuum cleaner's suction hose is connected via a quick-connect coupling (e.g., Figure 8 The nozzle structure component shown in the blowing unit 6 is connected to the suction port on the main body of the device, and the vacuum cleaner itself can come with a high-efficiency HEPA filter bag.

[0057] Control system: The main controller (not shown in the figure) is connected to the drive motor 21 of the screw mechanism 2 (such as a frequency converter), the solenoid valve of the pulse valve, and the start signal terminal of the vacuum cleaner, etc.

[0058] The main controller is configured with one or more of the following intelligent control strategies and operating processes: (1) Associated pulse blowing: The main controller dynamically adjusts the switching frequency of the pulse valve according to the running speed of the screw mechanism 2 (reflected by the frequency converter frequency F).

[0059] (2) Low-speed linkage: When the screw mechanism 2 runs at low speed (e.g., F<20Hz), the controller controls the pulse valve to enter the low-frequency pulse mode, such as "open for 2 seconds and close for 8 seconds", which not only ensures the loosening of the bottom fiber, but also achieves energy saving.

[0060] (3) High-speed linkage: When the spiral mechanism 2 runs at high speed (e.g., F≥20Hz), it indicates that the fiber input is large. The controller then controls the pulse valve to enter the high-frequency mode, such as "open for 5 seconds and close for 2 seconds", so as to provide stronger airflow support and ensure that there is no blockage under high load.

[0061] By intelligently controlling the pulse frequency and spiral speed, the airflow supply is precisely matched with the material demand. Compared with continuous air supply, the energy saving effect exceeds 40%, and the intermittent strong airflow impact is more effective in breaking down fiber clumps.

[0062] (4) Working mode of the integrated vacuum cleaner: When the main controller starts the spiral mechanism 2, it simultaneously sends a wireless or wired start signal to the vacuum cleaner, causing it to start working synchronously. The high negative pressure generated by the vacuum cleaner can more effectively suck up debris. Therefore, by using the vacuum cleaner to provide good suction for the suction unit, it has multiple advantages such as low cost, convenient maintenance (only the dust bag needs to be replaced), and high filtration accuracy, making it particularly suitable for small and medium-sized applications or applications that require frequent replacement of collection points.

[0063] In summary, through the coordinated work of various components within the equipment, such as pulsed air blowing to "shake" debris out of the fibers, and the high-powered vacuum cleaner to "collect" these debris in time, the two work together under the unified scheduling of the controller to form a highly efficient, energy-saving, and intelligent pneumatic auxiliary system for fiber processing.

[0064] Example 4: Screw mechanism with progressive compression function This embodiment demonstrates how the spiral mechanism itself achieves progressive compression. The difference between this embodiment and Embodiment 1 lies in the structural configuration of the spiral mechanism 2.

[0065] In one example, the screw mechanism 2 is configured as follows: on the one hand, the screw pitch (P) decreases linearly from 180 mm at the feed end to 100 mm at the discharge end. On the other hand, the screw shaft diameter (D) increases linearly from 50 mm at the feed end to 85 mm at the discharge end.

[0066] This embodiment uses a combination of "variable pitch + variable shaft diameter" design to make the cross-sectional area of ​​the material conveying channel gradually decrease along the process, thereby applying a gradually increasing mechanical extrusion force to the fibers.

[0067] Working process illustration: During the conveying process, the volume of fibers grasped by the spiral blades is gradually compressed, forming a relatively dense fiber flow before reaching the discharge port 103. Therefore, compared with the equal-pitch spiral of Example 1, the design of this embodiment enables the fibers to have a higher pre-compression degree before entering the collection device 3 (such as a collection bag), resulting in smoother discharge, less bridging at the outlet, and a significant improvement in the final collection density. This demonstrates that the spiral structure can improve the overall compaction effect.

[0068] It should be noted that the screw mechanism is configured to operate under gradually increasing mechanical extrusion pressure, which can be achieved through at least one of the following methods: a) The pitch of the screw mechanism gradually decreases along the conveying direction; b) The diameter of the screw shaft of the screw mechanism gradually increases along the conveying direction; c) The cross-sectional area of ​​the outlet channel of the screw mechanism gradually decreases along the conveying direction.

[0069] Therefore, the above design methods can be implemented individually or in combination.

[0070] Example 5: Collection device with molding die This embodiment demonstrates how to obtain regularly shaped recycled fibers.

[0071] In some embodiments, the collecting device 3 can be a replaceable flexible or semi-rigid container that can be quickly replaced, with its inlet sealed to the outlet via a sealing connection structure.

[0072] In some embodiments, a molding die is provided and connected at the discharge port 103 of Example 1. The molding die can be a long strip channel with a cross-section of 50mm×50mm square and a length of 300mm.

[0073] The fibers, initially compressed by the spiral mechanism 2, are further constrained and compressed as they are continuously fed into the square-section forming mold by the spiral mechanism 2, forming continuous fiber rods with a square cross-section. Therefore, by compressing the fibers into a regular geometric shape a second time, subsequent stacking, storage, and transportation are greatly facilitated, maximizing space utilization.

[0074] Example 5: Collection device with compression roller This embodiment demonstrates the introduction of a separate final compression device after the screw conveyor. In practice, a pair of final compression rollers (not shown) can be installed downstream of the discharge port 103. Both rollers are made of wear-resistant steel with knurled surfaces to increase friction. One roller is driven by a 0.75kW servo motor, and the other is a driven roller. The gap (G) between the two rollers is adjustable and initially set to 10mm.

[0075] Working process diagram: The fibers fed from the screw mechanism 2 enter between the two counter-rotating compression rollers. At this time, the fibers are forcibly pulled in and pass through the narrow roller gap, and are subjected to strong roller pressure, being compressed into thin sheets or dense strips, and then fall into the collection device. Therefore, the final compression by roller pressing can greatly increase the density of fibers, and is especially suitable for scenarios requiring extreme compaction.

[0076] Example 6: System integrating intelligent control and fluid optimization This embodiment demonstrates an intelligent control strategy. In this embodiment, the collection device also includes an intelligent control system, which is configured to: control the start, stop, and rotation speed of the screw mechanism according to a preset time interval or the material level signal of the collection chamber; and monitor the load current of the drive motor of the screw mechanism, and when the current continuously exceeds a set threshold, determine that the collection device is full or blocked, and trigger an alarm or shutdown.

[0077] System composition: The controller (such as PLC) is the core, connected to sensors for detection, such as one or more sensors, such as material level sensors (which can be RF capacitive sensors), motor current sensors, weighing sensors, pressure sensors (for hydraulic systems), etc. The process is monitored and collected in real time through the sensors; then, through actuators, such as motor frequency converters, fan contactors, hydraulic solenoid valves, pulse valves (for positive pressure fan pipelines), etc., intelligent control strategies are realized.

[0078] For example, in adaptive pulse airflow mode: the PLC controls the solenoid valves of the positive pressure fan's pipeline to operate in pulse mode. When the motor current increases (indicating high fiber resistance), the pulse duty cycle is increased (e.g., working for 15 seconds, then stopping for 5 seconds); conversely, it is decreased. Compared to continuous airflow, pulse mode is more energy-efficient and has better anti-clogging effects.

[0079] For example, in the overload and full-load judgment mode: the PLC continuously monitors the motor current. If the current exceeds threshold A (e.g., 120% of the rated current), it is judged as an overload warning and attempts to automatically reduce the speed. If the current continues to exceed a higher threshold B (e.g., 150%) and the weight no longer increases, it is judged as a full-load blockage, and the machine is immediately stopped and an alarm is triggered.

[0080] For example, weight-based process management: the system records the net weight of each bag of fiber, generates production reports, and automatically enters the next process after the target weight is reached (such as triggering the final pressure in Example 5 or prompting for replacement).

[0081] In summary, this embodiment upgrades the equipment into an adaptive, fault-resistant, and manageable intelligent system, significantly improving the equipment's reliability, ease of use, and production efficiency.

[0082] Example 7: The collection device is also equipped with a pre-treatment feeding mechanism for special materials. This embodiment demonstrates the adaptability of this equipment to difficult-to-process materials. In practice, a pretreatment mechanism is integrated at the feed inlet 102.

[0083] For example, the rotating dispersing roller: a roller driven by a 0.18kW motor with an adjustable speed and a surface covered with staggered stainless steel needles.

[0084] For example, a metal impurity adsorption device consists of a neodymium iron boron strong magnet plate placed obliquely on the feed channel.

[0085] For example, the pre-compression chamber: a small vertical chamber with a volume of about 5L, the bottom of which is controlled by a pair of programmable gates.

[0086] A diagram illustrating the coordinated operation of one or more pretreatment mechanisms: clumps of fiber can be broken up by the dispersing rollers, and can be attracted by the magnetic plate when passing metal impurities. The pre-compression chamber can collect a large amount of falling fiber by closing one end of the gate, and after accumulating a certain amount, the gate is quickly opened again, and the fiber falls into the main cavity in the form of "clumps", thereby increasing the initial density of the fiber and facilitating the rapid gripping and conveying by the spiral mechanism.

[0087] By designing a pre-treatment mechanism at the feed inlet, the feeding problem of special fibers such as those that are easy to entangle or contain impurities can be effectively solved. The equipment has good flexibility and adaptability and can meet the collection and application needs of various special fibers.

[0088] Example 8: Fiber Collection System with Multiple Units in Parallel This embodiment demonstrates a multi-station application system scenario utilizing the aforementioned collection equipment.

[0089] System configuration: In a large workshop, five collection devices as described in the aforementioned examples (such as Example 6) are connected in parallel to a fiber distributor and a vacuum cleaner via delivery pipes.

[0090] Working process illustration: The fiber distributor, according to preset logic, either evenly distributes fibers to each device or prioritizes feeding fibers to idle devices based on their material level. The controller monitors the operating status, output, and fault information of all devices in real time and generates a system-wide report. Therefore, through system integration design, it can meet the needs of simultaneous collection and processing at multiple workstations, realizing a modern workshop solution of distributed collection and centralized management, greatly improving the fiber collection efficiency and intelligent management level of large-scale production.

[0091] Example 9: Fiber Collection Method This embodiment is a fiber collection method based on the device or system in any of the foregoing examples, which dynamically collects fibers cut off by a wire loop.

[0092] refer to Figure 12 This embodiment illustrates a fiber collection method, which includes the following steps: Step S202, Dynamic Collection Step: The waste fibers cut off by the conductive ring are continuously or intermittently fed into the collection chamber; Step S204, Integrated conveying and compression step: Through the screw mechanism, the waste fibers are conveyed from the collection chamber to the collection device, and the preliminary compression and compaction treatment of the waste fibers is completed simultaneously. Step S206, Sealing and Packaging Step: The waste fibers after initial compression and compaction are directly pushed into the collection device for a second compression and compaction process before sealing.

[0093] Through the above steps, the waste fibers cut off by the conductive ring can be dynamically and compressively collected and cleaned. This not only enables automated collection and processing but also minimizes secondary pollution such as flying waste fibers. Furthermore, the collected material forms highly compacted recyclables, facilitating subsequent transportation and handling. This significantly saves storage space and collection costs, resulting in substantial economic benefits and providing strong support for enterprises to reduce costs and increase efficiency.

[0094] The following examples will provide further illustration.

[0095] In one example, the fiber collection method is performed using the device described in the previous embodiment 1.

[0096] The execution device is the device described in Example 1 or Example 2, including a feeding chamber, an equal pitch screw mechanism, a straight cylindrical discharge port, a woven bag collection device, etc.

[0097] Regarding the dynamic collection step: Operators can continuously and evenly feed the loose waste fibers generated during the conductive ring shearing process into the collection chamber through the feed inlet at the top of the equipment. The feeding rate is maintained at a level that matches the equipment's processing capacity to avoid instantaneous overfeeding. Continuous feeding ensures the continuity of subsequent steps, laying the foundation for "dynamic" collection.

[0098] In addition, after the fibers are naturally accumulated in the cavity, the positive pressure blower at the bottom can provide airflow to keep the fibers in a "fluidized" loose state, which is convenient for the spiral mechanism to grab and transport them later.

[0099] Regarding the integrated conveying and compression process: Start the screw mechanism and its drive motor, running them at a constant speed (e.g., 20 rpm). The screw blades capture the loose fibers at the bottom of the cavity and steadily push them towards the discharge port along the conveying path. During this process, due to the space constraints of the screw channel and the continuous thrust of the blades, the fibers are initially compressed and densified while being conveyed. The "integrated" process is achieved by completing both conveying and initial compression in the same process, using the same mechanism (screw). The principle is to use mechanical extrusion force to change the bulky shape of the fibers while they are being moved, thus increasing the conveying density through initial compression, for example, from approximately 10-30 kg / m³ at the time of input. 3 Increased to 60-65 kg / m 3 This achieves significant "initial compression" capability, creating favorable conditions for final high-density packaging.

[0100] In addition, a negative pressure fan that provides suction can also be started simultaneously to provide auxiliary suction inside the cavity.

[0101] Regarding the sealing process: The initially compressed fiber stream is directly pushed into a woven bag (i.e., the collection device) tightly connected to the outlet via a pneumatic seal ring under the continuous thrust of the screw mechanism, thus achieving secondary compression and compaction. After entering the woven bag, the fibers accumulate and compact due to the limited space and the continuous thrust of subsequent fibers. This compaction (i.e., "secondary compression") within the sealed container, achieved by the material's own influx, continuously increases the density inside the bag as fibers are added. When the weight of the fibers in the collection bag reaches its capacity limit (e.g., determined by experience over time or equipment current), feeding and the screw mechanism are stopped. Finally, the operator releases the pneumatic seal, ties the bag tightly, and removes it, completing one full sealing cycle. A new empty bag is then used to begin the next collection cycle.

[0102] In summary, this embodiment achieves a unified process of "collection" and "packaging," and the fully enclosed collection process eliminates secondary pollution. Furthermore, the "secondary compression" further deepens and compacts the fiber state beyond the "initial compression," allowing for a further increase in overall density, such as to 70-75 kg / m³. 3 The resulting fiber block has a stable structure, making it easy to handle and store later.

[0103] In one example, the collection process is implemented through intelligent control and enhanced compaction. Specifically, this embodiment, based on the above example, introduces intelligent control strategies and external enhanced compaction methods, resulting in a more intelligent device with higher collection capabilities.

[0104] Regarding the dynamic collection process: The operator puts the waste fiber into the collection chamber. This process can be linked with the upstream conductive ring production line to achieve automatic and intermittent feeding. That is, when the production line accumulates a certain amount of fiber, the automatic valve opens and sends the fiber into the collection chamber.

[0105] Regarding intelligent intervention: After the material level sensor inside the cavity detects a high material level signal, it transmits the signal to the controller, which then automatically starts the subsequent process.

[0106] Regarding the integrated conveying and compression process: The controller automatically starts the screw mechanism according to a preset program. Unlike the previous implementation example, the speed of the screw mechanism in this example is not constant; the controller monitors the load current of the drive motor in real time for adaptive adjustment. For example, if the current value is below the set range, it indicates low fiber resistance, and the controller will appropriately increase the speed to accelerate processing. If the current value is close to or exceeds the safety threshold, it indicates high fiber resistance (possibly due to high humidity or inherent looseness), and the controller will automatically reduce the speed to prevent equipment overload. Additionally, the pulse frequency of the blowing unit and / or suction unit can be synchronously adjusted to different operating levels to better loosen the fibers before conveying.

[0107] This example employs an "adaptive delivery compression based on load feedback" strategy, which ensures the stability and efficiency optimization of the method under different working conditions, and embodies intelligent "integrated delivery compression".

[0108] Regarding the sealed packaging and enhanced secondary compression steps: The initially compressed fibers are pushed into a specially designed collection bag placed within a rigid support frame, and the weight of the fibers inside the bag is monitored in real time by a weighing sensor. When the weight reaches the controller's preset value (e.g., 190 kg), the controller automatically executes the following sequence: a. Stop the screw mechanism to complete fiber conveying; b. Activate the hydraulic system to drive the pressure plate downwards, applying enormous mechanical pressure (e.g., 8 MPa) to the initially compacted fiber blocks inside the bag, and holding the pressure for 15 seconds, thereby performing enhanced secondary compression. Because the natural secondary compaction previously achieved inside the bag by the fiber's thrust is a "first-stage secondary compression," the strong compaction applied by the external pressure plate at this moment performs "enhanced secondary compression" or "final compression," which can greatly improve the final density of the recycled fibers.

[0109] Regarding sealing: After the pressure holding period, the pressure plate returns to its original position. The controller issues an audible and visual alert, and the operator replaces the collection bag. The system automatically records the weight, time, and other data collected this time.

[0110] By introducing an enhanced compaction step with external power, the method achieves maximum compaction effect, for example, the density of collected fibers can exceed 100 kg / m³. 3 It even reaches 120 kg / m 3 This process forms extremely regular and hard "fiber bricks," greatly improving the efficiency of subsequent processing. Furthermore, the entire process, including startup, adjustment, termination, and recording, is completed automatically by the system, achieving a high degree of automation and intelligence.

[0111] Based on the combination of intelligent control and enhanced compaction, the collection process can achieve a high level of intelligent production application, and significantly improve the quality (density) and automation of fiber recycling.
