Description

Technical Field

[0001] This invention relates to the field of winding machine head pickers, and more particularly to a broken wire recovery device and a head picker. Background Technology

[0002] Winding machines are essential equipment in textile production, primarily used to rewind yarn bobbins or skeins produced during the spinning process into larger, more structurally sound cones. They also remove impurities and defects from the yarn, improving its quality. Through precise tension control and winding, they ensure the yarn is neatly arranged and of uniform density, facilitating efficient subsequent warping, knitting, or dyeing processes. Modern winding machines are typically equipped with electronic yarn clearers and automatic splicing devices, achieving high speed, automation, and intelligence, significantly improving production efficiency and yarn quality. They are key processing machinery connecting spinning and weaving in the textile industry.

[0003] The yarn picker (also known as a splicer or automatic splicing device) of a winding machine is a key component in the winding process. It is primarily responsible for automatically finding, guiding, and splicing yarn when yarn breaks or bobbins need to be replaced. When yarn breaks unexpectedly during high-speed winding, or when the existing bobbin runs out and needs to be replaced with a new one, the yarn picker can quickly capture the yarn end and splice the two ends together mechanically or through airflow, forming a strong and smooth splice. This ensures continuous and automated operation of the winding process, effectively reducing manual intervention and improving production efficiency and bobbin quality.

[0004] Currently, the existing wire breakage recovery devices of the head picker use negative pressure to recover the broken wires through the pipes. However, the broken wires are prone to getting tangled, accumulating, and sticking to the inner wall of the pipes, forming blockage points and increasing energy consumption. Summary of the Invention

[0005] This application discloses a broken wire recycling device and a wire picker to solve the technical problem in related technologies where broken wires easily become entangled, accumulated, and stuck on the inner wall of the pipe, forming blockage points and causing increased energy consumption.

[0006] To solve the above problems, the present invention adopts the following technical solution: In a first aspect, this application discloses a broken filament recycling device, comprising: The wire return box has an air inlet and an air outlet. The air inlet is set to correspond to the head picker body, and the air outlet is used to connect to the negative pressure equipment. The adsorption mechanism includes a power source and multiple metal plates. The multiple metal plates are arranged in parallel and spaced apart in the wire return box. The power source is connected to the multiple metal plates so that an electrostatic field is formed between two adjacent metal plates. The interception net, located inside the wire return box and arranged in an electrostatic field, is used to intercept broken wires that are attracted by the metal plate.

[0007] In some designs, the interception net bends, passing through and encircling multiple metal plates in sequence; The interception net is arranged in close contact with or adjacent to the surface of the metal plate.

[0008] In some designs, the interception net is connected end to end and can be moved to change its position; The broken wire recovery device also includes a drive mechanism, which is connected to the interception net and is used to drive the interception net to move.

[0009] In some designs, the drive mechanism includes a chain, gears, and a drive unit; the chain is mounted on the interception net, the gears are mounted in the winding box and mesh with the chain, and the drive unit is used to drive the gears to rotate. And / or, the broken wire recycling device also includes a wire scraping mechanism, which is located in the wire return box and is used to scrape off broken wires from the interception net.

[0010] In some designs, the drive unit includes a motor, a belt, and two pulleys; the belt is fitted over the two pulleys, one of which is connected to a gear, and the other is connected to the output shaft of the motor.

[0011] In some designs, the wire return box is equipped with a sliding track, and the interception net is equipped with pulleys, which are embedded in the sliding track. And / or, the outer wall of the return wire box is wrapped with an insulating layer.

[0012] In some designs, multiple metal plates are arranged in multiple columns, with each column including at least two metal plates; In this arrangement, any two adjacent columns are staggered.

[0013] In some designs, the scraping mechanism includes a scraper and a telescopic rod. The scraper is rotatably connected to the inner wall of the wire return box, and one end of the telescopic rod is rotatably connected to the inner wall of the wire return box, while the other end is rotatably connected to the scraper to drive the scraper to contact the intercepting net.

[0014] In some designs, the inner wall of the wire return box is provided with a groove, and the telescopic rod is located in the groove; when the wire scraping mechanism is not in operation, the end face of the scraper is flush with the end face of the groove. And / or, the contact surface between the scraper and the intercepting net is provided with a flexible part; And / or, the circumferential wall of the scraper is connected to the inner wall of the wire return box through a deformation part, so as to form a sealed space between the scraper and the wire return box; And / or, the bottom of the waste paper box is equipped with an openable and closable drawer structure. Secondly, this application also discloses a wire picker, including a wire picker body, a negative pressure device and the broken wire recovery device mentioned in the first aspect, wherein the wire picker body is provided corresponding to the air inlet and the negative pressure device is connected to the air outlet.

[0015] The technical solution adopted in this invention can achieve the following beneficial effects: The broken yarn recovery device of this application guides the generated textile broken yarns to the air inlet of the yarn recovery box by the head picker body. A suction airflow generated at the air outlet by a negative pressure device draws the yarns into the box. Inside the yarn recovery box, multiple metal plates powered by a power source create an electrostatic field, instantly charging the passing broken yarns. The charged broken yarns are then directionally adsorbed onto the surface of the interception net and captured under the action of the electric field. This active adsorption via the electrostatic field physically reduces the possibility of broken yarns entering the negative pressure pipeline, thus greatly avoiding the vicious cycle of blockages, increased resistance, and soaring fan shaft power caused by broken yarns entangled and accumulated in the pipeline. This significantly reduces the overall system energy consumption and improves operational stability. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0020] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0021] During their research on the broken yarn recovery device for the yarn picker, the inventors discovered that when existing yarn pickers use negative pressure pipelines to recover broken yarns, textile broken yarns (especially long filaments and highly entangled fibers) easily become entangled, accumulated, and adhered to the inner wall of the pipeline during long-distance transport, forming blockage points. These blockage points significantly reduce the effective flow cross-sectional area of ​​the pipeline. Therefore, in order to maintain the necessary suction airflow to capture broken yarns, the system must significantly increase the head of the fan (or negative pressure source) to overcome the rapidly increasing frictional and local resistance. The fan's operating point is thus forced to move to a region of low efficiency and high pressure differential, resulting in a significant increase in its shaft power and a substantial increase in energy consumption. More seriously, this blockage often exhibits an unstable development trend, which may cause airflow pulsation or even fan surge, further reducing system efficiency and forming a vicious cycle of "blockage → increased resistance → increased power consumption → some broken yarns being retained due to insufficient suction → exacerbated blockage," causing energy to be continuously wasted while maintaining basic functions.

[0022] The following is in conjunction with the appendix Figures 1 to 5 The present application provides a detailed description of a broken wire recycling device 100 and a wire picker 200 through specific embodiments and application scenarios.

[0023] Some embodiments of this application disclose a broken wire recycling device 100, including a wire recycling box 110, an adsorption mechanism, an interception net 130, a driving mechanism 140, and a wire scraping mechanism 150.

[0024] like Figure 1As shown, the yarn return box 110 has an air inlet 111 and an air outlet 112. The air inlet 111 is located corresponding to the yarn picker body 210, and the air outlet 112 is used to connect to a negative pressure device. The negative pressure device creates a certain negative pressure inside the yarn return box 110. During the yarn picker 200 connection process, when the yarn picker body 210 grabs and processes the yarn breakage, the generated textile breakage enters the yarn return box 110 through the air inlet 111, completing the collection of external breakage.

[0025] In this embodiment, the negative pressure device can be a fan, vacuum generator, vacuum cleaner, etc., and can be flexibly set according to usage requirements. This embodiment does not limit this.

[0026] like Figure 2 and Figure 4 As shown, the adsorption mechanism includes a power source and multiple metal plates 120. The metal plates 120 are arranged in parallel and spaced apart within the yarn return box 110. The power source is connected to the metal plates 120 to create an electrostatic field between adjacent metal plates 120. The power source supplies power to the multiple metal plates 120 arranged in parallel and spaced apart within the yarn return box 110, creating a strong electrostatic field between adjacent metal plates 120. When airflow containing broken textile fibers passes through, the broken fibers become charged due to induction or contact, and then move towards the surface of the metal plates 120 under the action of the electric field force, achieving efficient separation from the airflow. Through active electric field adsorption, most of the broken fibers are captured and fixed before entering the conveying pipe, thereby reducing the possibility of broken fibers entangled, stuck on the walls, and forming blockages in the negative pressure pipe. This largely avoids the vicious cycle of increased system resistance, increased fan head to maintain airflow, increased shaft power, and airflow pulsation caused by blockages, significantly reducing system energy consumption and improving operational stability.

[0027] It should be noted that the increased power consumption of the adsorption mechanism is fixed and minimal, but it significantly reduces the likelihood of broken wires entering the pipe, thereby largely preventing the nonlinear surge in system resistance caused by blockage. This allows the main negative pressure fan to operate continuously in its high-efficiency range without significantly increasing its head to overcome the rapidly increasing frictional resistance. The substantial reduction in its shaft power far outweighs the small amount of energy consumed by electrostatic adsorption itself. Therefore, this embodiment, by introducing localized and controllable low power consumption, frees the entire system from the vicious cycle of blockage and high power consumption, achieving a net reduction in total energy consumption and a fundamental improvement in operational stability.

[0028] like Figure 2 and Figure 4As shown, the intercepting net 130 is located inside the return yarn box 110 and arranged in an electrostatic field to intercept broken yarns adsorbed by the metal plate 120. When the metal plate 120 is energized, an electrostatic field is formed in its gaps, causing the passing textile broken yarns to quickly become charged. Under the action of the electric field force, these charged broken yarns are directionally driven to the surface of the intercepting net 130 and firmly adsorbed and captured, thus achieving functional separation between the metal plate 120 and the intercepting net 130. The metal plate 120 is used to generate a stable electrostatic field, avoiding the weakening of the electric field or short circuit caused by direct adhesion of broken yarns. The intercepting net 130, as a dedicated high-efficiency collection surface, provides a larger adsorption area and mechanical interception capacity due to its mesh structure, ensuring a high capture rate and easy cleaning of broken yarns. This more reliably prevents broken yarns from entering the negative pressure pipeline at the source, eliminating the vicious cycle of blockage and system energy consumption caused by this.

[0029] In this embodiment, the intercepting net 130 is made of conductive material and grounded. The grounded conductive intercepting net 130 can quickly conduct the charge carried by the adsorbed broken wire to the ground, achieving charge neutralization. This avoids the repulsive electric field generated by charge accumulation on the insulating material, thereby ensuring the continuous and strong driving and adsorption effect of the electrostatic field on subsequent broken wires; on the other hand, it also allows the broken wire to be more firmly adsorbed onto the net surface through mirror force, preventing it from falling off due to airflow pulsation.

[0030] like Figure 2 and Figure 4 As shown, the intercepting net 130 is bent and passes through and surrounds multiple metal plates 120 in sequence; the intercepting net 130 is arranged in close contact with or adjacent to the surfaces of the metal plates 120. The intercepting net 130, bent and surrounding multiple metal plates 120, is almost completely immersed in the electrostatic field and maintains a small gap with the surfaces of the metal plates 120. This allows textile filaments passing between the metal plates 120 to be quickly captured by the adjacent grounded intercepting net 130 with a very strong electric field force the moment they become charged, greatly shortening the suspension time and escape possibility of the filaments in the airflow. At the same time, this structure significantly increases the effective adsorption area and makes the filaments more concentrated and firmly attached to the intercepting net 130 rather than the surface of the metal plates 120. This ensures ultra-high capture efficiency, makes maintenance and cleaning easier, and maintains the long-term stability of the electric field.

[0031] like Figure 2 and Figure 4 As shown, the interceptor net 130 is connected end to end and can be moved to change its position. When the interceptor net 130 becomes saturated in the effective adsorption area due to the collection of broken filaments and its efficiency begins to decline, the saturated old working surface can be moved out of the electrostatic field area by moving the interceptor net 130, while the clean area is moved into the electrostatic field to become a new working surface. This ensures that the adsorption efficiency of the interceptor net 130 on the working surface is always maintained close to the optimal state, avoiding electric field shielding and efficiency decay caused by the accumulation of broken filaments.

[0032] like Figure 2 and Figure 4 As shown, the drive mechanism 140 is connected to the interceptor net 130 and is used to drive the interceptor net 130 to move. The drive mechanism 140 enables the interceptor net 130 to move automatically, promptly removing the saturated working surface from the electrostatic field and simultaneously moving the clean area into the working position. This maintains the long-term stability of the electrostatic field capture efficiency and avoids performance degradation caused by the accumulation of broken fibers. Furthermore, the drive mechanism 140 eliminates the need for manual movement of the interceptor net 130, increasing safety during use.

[0033] like Figure 3 As shown, the drive mechanism 140 includes a chain 141, a gear 142, and a drive component. The chain 141 is disposed on the interception net 130, and the gear 142 is rotatably disposed on the return wire box 110 and meshes with the chain 141. The drive component is used to drive the gear 142 to rotate. When the drive component is started as a power source, it drives the gear 142 connected to its output shaft to rotate on the return wire box 110. Since the gear 142 meshes with the chain 141 disposed on the interception net 130, the rotational motion of the gear 142 is converted into the linear or circular movement of the chain 141, thereby driving the entire interception net 130, which is fixed to the chain 141, to move stably and continuously in translation or cyclic operation within the return wire box 110, thus realizing the automated and periodic switching of the working surface and non-working surface positions of the interception net 130.

[0034] like Figure 3 As shown, the drive unit includes a motor 145, a belt 144, and two pulleys 143. The belt 144 is fitted onto the two pulleys 143, one of which is connected to a gear 142, and the other is connected to the output shaft of the motor 145. After the motor 145 starts, its output shaft drives the pulley 143 connected to it to rotate, and transmits the power to the other pulley 143 coaxially connected to the gear 142 through the belt 144, thereby causing the gear 142 to rotate synchronously. The gear 142 meshes with the chain 141 fixed on the interception net 130, ultimately converting the rotational motion of the motor 145 into the linear or circular motion of the chain 141, thereby smoothly and reliably driving the entire interception net 130 to move as needed, realizing the automatic switching of the working face.

[0035] In this preferred embodiment, the diameter of the pulley 143 mounted on the output shaft of the motor 145 is smaller than the diameter of the pulley 143 coaxially connected to the gear 142. This arrangement allows the larger driving torque required to move the interceptor net 130 to be provided by a smaller, higher-speed, and generally more economical and efficient motor 145, thereby achieving optimized matching and stable drive of the system.

[0036] like Figure 2As shown, the return wire box 110 is equipped with a sliding track, and the intercepting net 130 is equipped with a pulley 131, which is embedded in the sliding track. The pulley 131 is embedded in the sliding track to ensure that the intercepting net 130 can only move smoothly along the preset trajectory under the drive mechanism 140, effectively preventing the net surface from deviating, twisting, or jamming due to uneven force or meshing gap of the chain 141; at the same time, this rolling friction method significantly reduces the resistance when the intercepting net 130 moves, which not only reduces the load and energy consumption of the drive components, but also reduces mechanical wear, thereby ensuring the long-term reliability, smoothness, and precision of the working surface switching action. It is a key mechanical guarantee for maintaining the continuous, stable, and maintenance-free operation of the entire electrostatic adsorption system.

[0037] The outer wall of the wire return box 110 is covered with an insulating layer. The insulating layer can completely isolate the high-voltage electrostatic field inside the wire return box 110 from the external environment and operators, effectively preventing the risk of high-voltage breakdown or electric shock, while avoiding interference from external metal parts with the electric field distribution, ensuring the safety of system operation and the stability of electrostatic adsorption.

[0038] like Figure 2 and Figure 4 As shown, multiple metal plates 120 are arranged in multiple columns, with each column including at least two metal plates 120; any two adjacent columns are staggered. Each column of multiple metal plates 120 forms a uniform electrostatic field in the longitudinal direction, while the staggered arrangement of adjacent columns allows the electric field regions of each column to overlap and complement each other in the transverse direction, thus constructing a composite electrostatic field with no dead zones and a more uniform intensity distribution within the entire flow cross-section of the return wire box 110. This optimized electric field layout ensures that regardless of where the broken textile fibers pass through with the airflow, they can be immediately and effectively polarized and charged by the high-intensity electric field, greatly reducing the possibility that broken fibers may not be fully charged and thus escape due to being at the edge or weak region of the electric field. Simultaneously, the uniform electric field distribution also helps broken fibers migrate more quickly and concentratedly to the interception net 130, thereby significantly improving the single-capture efficiency and system reliability, providing a more solid guarantee for breaking the vicious cycle of pipeline blockage.

[0039] In this preferred embodiment, the multiple metal plates 120 are arranged in two rows, with two metal plates 120 in the row near the air inlet 111 and three metal plates 120 in the row near the air outlet 112.

[0040] like Figure 4As shown, the scraping mechanism 150 is located inside the wire return box 110 and is used to scrape off broken wires from the interception mesh 130. The scraping mechanism 150 automates the cleaning of collected broken wires on the interception mesh 130. When the adsorption mechanism is closed, the scraping mechanism 150 scrapes off the broken wires attached to the mesh surface, causing them to fall off. This process directly prevents the interception mesh 130 from becoming clogged due to excessive accumulation of broken wires, increasing airflow resistance, and causing electrostatic shielding effects, thus ensuring that the interception mesh 130 always maintains high adsorption capacity and low air permeability resistance.

[0041] like Figure 4 As shown, the scraping mechanism 150 includes a scraper 151 and a telescopic rod 152. The scraper 151 is rotatably connected to the inner wall of the wire return box 110. One end of the telescopic rod 152 is rotatably connected to the inner wall of the wire return box 110, and the other end is rotatably connected to the scraper 151 to drive the scraper 151 to contact the intercepting net 130. As an active driving component, the telescopic rod 152 pushes the scraper 151, which is rotatably connected to it, to rotate around the rotatable connection point with the inner wall of the wire return box 110 when it extends and retracts. By controlling the extension length of the telescopic rod 152, the rotation angle of the scraper 151 can be precisely adjusted, thereby driving the cutting edge of the scraper 151 to press against the surface of the moving intercepting net 130, and continuously scraping off the broken wires attached to the net using relative motion, thus achieving automated cleaning.

[0042] In this preferred embodiment, the contact surface between the scraper 151 and the interceptor net 130 is provided with a flexible portion. The flexible portion ensures that the scraper 151 effectively removes broken wires while preventing physical damage or excessive wear to the interceptor net 130 caused by rigid contact, thereby protecting the integrity and conductivity of the interceptor net 130 and ensuring the long-term stable operation of the electrostatic adsorption system. The flexible portion can be made of polyurethane material.

[0043] In this embodiment, there can be multiple telescopic rods 152 to ensure the smooth rotation of the scraper 151. One of the telescopic rods 152 is an electric telescopic rod 152, a pneumatic telescopic rod 152, or a hydraulic telescopic rod 152 to enable the scraper 151 to rotate. The other telescopic rods 152 are manual telescopic rods 152, which mainly serve as auxiliary guides and stable supports, together forming a stable multi-point support to ensure that the scraper 151 will not wobble or get stuck during the rotation and scraping process, thereby achieving uniform and stable contact with the interception net 130.

[0044] like Figure 4As shown, the inner wall of the wire return box 110 is provided with a groove 113, and the telescopic rod 152 is located in the groove 113. When the wire scraping mechanism 150 is not in operation, the end face of the scraper 151 is flush with the end face of the groove 113. When the wire scraping mechanism 150 is not in operation, the scraper 151 can be completely retracted into the groove 113, so that its end face is flush with the inner wall of the wire return box 110, thereby avoiding interference from the scraper 151 to the normal movement of the interception net 130, the airflow channel, and the broken wire collection process.

[0045] like Figure 5 As shown, the circumferential wall of the scraper 151 is connected to the inner wall of the return wire box 110 through the deformation part 153, so that a sealed space is formed between the scraper 151 and the return wire box 110. By connecting the scraper 151 and the inner wall of the return wire box 110 through the deformation part 153, the degree of freedom required for the movement of the scraper 151 is realized, and a dynamic sealed space is constructed between it and the box body. This can effectively prevent the scraped short fibers, dust and other impurities from entering and accumulating inside precision moving parts such as the telescopic rod 152 and the rotating connection point, thereby eliminating the possibility of mechanism jamming, accelerated wear or malfunction, and significantly improving the long-term working reliability of the scraper mechanism 150; at the same time, the sealed space also prevents airflow from leaking out from this point, maintaining the stability of the negative pressure and airflow field inside the return wire box 110, and further ensuring the overall efficiency of electrostatic adsorption and broken wire recovery.

[0046] In this preferred embodiment, the deformable part 153 is a flexible pleated sleeve.

[0047] like Figure 1 As shown, the bottom of the wire recycling box 110 is provided with an openable and closable drawer structure 114. The drawer structure 114 is used to collect broken wires scraped off by the scraper 151. The openable and closable drawer structure 114 can easily clean the collected broken wires, simplify maintenance operations, reduce downtime, and help maintain a clean and stable working environment inside the wire recycling box 110.

[0048] Some embodiments of this application also disclose a head picker 200, including a head picker body 210 and a broken wire recycling device 100.

[0049] like Figure 1As shown, the head picker body 210 is positioned corresponding to the air inlet 111. During the splicing process, the head picker body 210 guides the generated textile filaments to the air inlet 111 of the return yarn box 110; the negative pressure device draws in through the air outlet 112, forming a directional airflow that sucks the filaments into the return yarn box 110; a group of metal plates 120 powered by a power supply generates a strong electrostatic field inside the return yarn box 110, causing the filaments to quickly become charged; the charged filaments are driven by the electric field force to the surface of the grounded and cyclically moving interceptor net 130 and are firmly adsorbed; the drive mechanism 140 moves the interceptor net 130, causing its saturated area to move out of the electrostatic field, while a clean area enters to maintain efficient adsorption; the portion of the interceptor net 130 that has moved to the non-working surface is automatically scraped off by the scraping mechanism 150, and the filaments fall into the drawer structure 114 at the bottom for collection. The entire process achieves the collection of filaments before they enter long-distance pipelines, greatly solving the problem of the vicious cycle of pipeline blockage.

[0050] It should be noted that the yarn picker body 210 can accurately locate and grab the broken ends of the yarn during the yarn picker 200 splicing process, and complete the splicing action. At the same time, it can efficiently and centrally guide and throw the textile broken filaments generated by cutting or peeling to the vicinity of the air inlet 111 of the return yarn box 110.

[0051] It should also be noted that since the head picker body 210 is existing technology and is not an improvement in this embodiment, its specific structure will not be described in detail here.

[0052] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0053] Furthermore, it should be noted that the scope of the methods and apparatus in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in the reverse order, depending on the functions involved. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. In addition, features described with reference to certain examples may be combined in other examples.

[0054] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
