Description

Technical Field

[0001] This utility model relates to the field of broken yarn removal technology, specifically a broken yarn removal component for spandex-covered yarn transmission. Background Technology

[0002] If a spandex-covered yarn breaks, the broken section must be removed immediately; otherwise, it will seriously affect the quality of the finished yarn, the operational stability of the equipment, and the usability of the entire batch of products.

[0003] Patent CN212771174U discloses a waste yarn cutting device for a covered yarn machine. Key technical features include a mounting plate and a yarn sensor mounted on a frame. The mounting plate has a mounting groove for placing the yarn sensor. A clamping assembly, which engages with one side wall of the mounting groove, is also provided on the mounting plate. The clamping assembly includes a clamping block, a first spring, and a pull rod. A fixing groove is formed on the groove wall of the mounting groove, and a clearance hole is formed at the bottom of the fixing groove, penetrating the mounting plate. The clamping plate is located on one side of the mounting groove. One end of the first spring is fixed to the clamping block, and the other end is fixed to the bottom of the fixing groove. One end of the pull rod is fixed to the clamping block, and the other end extends through both the first spring and the clearance hole to the outside of the mounting plate. Disassembly is very convenient when maintaining or replacing the yarn sensor.

[0004] As shown in the above technology, yarn breakage can occur during the process of covering ordinary spandex yarn. Generally, automatic equipment is used to remove broken yarns. However, when there are abnormal situations such as frequent yarn breakage, sensor failure, or broken yarn entanglement in the guide mechanism, manual intervention by the operator is still required to confirm the fault location, clean up the entangled yarn, and perform necessary component maintenance. Existing equipment is installed by stacking a large number of bolts, which makes it difficult to disassemble. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a spandex-covered yarn transmission interruption yarn removal component, which solves the problem that existing equipment is difficult to disassemble due to its installation using a large number of bolts.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spandex-covered yarn transmission interruption yarn removal component, comprising:

[0007] The working frame has an installation groove on one side, a guide plate is fixedly connected to one side of the working frame, and an automatic wire drawing unit is fixedly connected to the middle of one side of the working frame via a bracket.

[0008] A broken filament removal assembly, one side of which is movably connected to one side of the working frame, is used to directly replace broken filaments that have become entangled during the spandex coating process.

[0009] A covering guide assembly is provided, the bottom of which is rotatably connected to one side of the inner wall of the working frame. The covering guide assembly is used to perform a full covering operation on the spandex yarn.

[0010] Preferably, the broken wire removal assembly includes a movable plate movably connected to the surface of the working frame, a screw rod penetrating the surface of the movable plate, a fixed frame plate fixedly connected to one side of the movable plate, a photoelectric sensor fixedly connected to one side of the movable plate, and an outer wire reel fixedly connected to one side of the movable plate via a synchronization plate.

[0011] Preferably, a fixing unit is fixedly connected to one side of the top of the working frame. The fixing unit includes a baffle, a spring is fixedly connected to one side of the baffle, a folding plate is fixedly connected to one end of the spring, and a connector is fixedly connected to one side of the folding plate.

[0012] Preferably, a threaded sleeve is fixedly connected to one side of the working frame surface, and the threaded sleeve is adapted to the screw rod.

[0013] Preferably, the covering guide assembly includes a chassis rotatably connected to the bottom of the inner wall of the working frame, and one end of the chassis output shaft is fixedly connected to a core shaft via a coupling.

[0014] Preferably, a guide plate is fixedly connected to one side of the working frame surface, and the surface of the guide plate is provided with a guide groove.

[0015] This invention provides a component for removing interrupted yarns during the transport of spandex-covered yarns. Compared with the prior art, it has the following advantages:

[0016] 1. This spandex-covered yarn transmission interruption yarn removal component utilizes the setting of the interruption yarn removal component. Simply pull the folding plate to separate the connector from the mounting groove for horizontal separation, and then rotate the screw rod for vertical separation. This allows for easy disassembly of the outer yarn reel as a whole, facilitating manual cleaning of the wound yarn, stopping the equipment for inspection and inspection of the yarn pulling mechanism, and replacing the reel. The related structure is simple and easy to implement.

[0017] 2. The spandex covered yarn transmission interruption yarn removal component utilizes the setting of the covered yarn guide component. By setting a guide plate and guide groove on the top of the chassis, it avoids the covered yarn from deviating, jumping or knotting due to static electricity, airflow or mechanical vibration. The guide groove forces the covered yarn to follow a fixed route, suppressing its free movement space. The distance between the guide plate and the core shaft can ensure that the covered yarn and the core yarn do not interfere with each other before they merge, ensuring that the outer yarn is controlled before merging. After a yarn breakage, it is easy to re-thread and check the trajectory when replacing the yarn. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides two technical solutions:

[0026] Example 1: A spandex-covered yarn transmission interruption removal assembly, comprising:

[0027] The working frame 1 has an installation groove 2 on one side and a guide plate 3 fixedly connected to one side of the working frame 1. The surface of the guide plate 3 is polished smooth. An automatic wire drawing unit 4 is fixedly connected to the middle of one side of the working frame 1 through a bracket.

[0028] Broken filament removal component 5, one side of which is movably connected to one side of the working frame 1, is used to directly replace broken filaments after they have become entangled during the spandex coating process.

[0029] The bottom of the wrapping guide component 6 is rotatably connected to one side of the inner wall of the working frame 1. The wrapping guide component 6 is used to fully wrap the spandex yarn. With the setting of the broken yarn removal component 5, simply pull the folding plate 563 to separate the connector 564 from the mounting groove 2 for horizontal separation, and then rotate the screw rod 52 for vertical separation. This allows for easy disassembly of the outer wire reel 55, facilitating manual cleaning of the wound yarn, stopping the equipment for inspection and removal of the wire pulling mechanism, and replacing the reel. The related structure is simple and easy to implement.

[0030] Example 2 differs from Example 1 mainly in that: a spandex-covered yarn transmission interruption yarn removal assembly 5 includes a movable plate 51 movably connected to the surface of the working frame 1, a screw rod 52 penetrating the surface of the movable plate 51, a fixed frame plate 53 fixedly connected to one side of the movable plate 51, a photoelectric sensor 54 fixedly connected to one side of the movable plate 51, and an outer yarn reel 55 fixedly connected to one side of the movable plate 51 via a synchronization plate. The outer yarn can be polyester, nylon, or polypropylene yarn. A fixed unit 56 is fixedly connected to one side of the top of the working frame 1. The fixed unit 56 includes a baffle 561, a spring 562 fixedly connected to one side of the baffle 561, a folding plate 563 fixedly connected to one end of the spring 562, and a connector 564 fixedly connected to one side of the folding plate 563. A threaded sleeve 57 is fixedly connected to one side of the surface of the working frame 1, and the threaded sleeve 57 is compatible with the screw rod 52. The covering guide assembly 6 includes a chassis 61 rotatably connected to the bottom of the inner wall of the working frame 1. One end of the output shaft is fixedly connected to the core shaft 62 via a coupling. The core shaft 62 is a spandex yarn shaft. A guide plate 63 is fixedly connected to one side of the surface of the working frame 1. A guide groove 64 is provided on the surface of the guide plate 63. Depending on the actual situation, the bottom of the guide groove 64 can be V or U-shaped to guide the two left and right covering yarns to converge on the surface of the spandex yarn along a predetermined path, ensuring covering accuracy and symmetry. A certain distance is reserved between the guide plate 63 and the spandex yarn shaft to form a yarn pretreatment area, which improves tension stability. By setting the covering guide component 6, the guide plate 63 and the guide groove 64 are set on the top of the chassis 61 to prevent the covering yarn from deviating, jumping or knotting due to static electricity, airflow or mechanical vibration. The guide groove 64 forces the covering yarn to follow a fixed route, suppressing its free movement space. The distance between the guide plate 63 and the core shaft 62 can ensure that the covering yarn and the core yarn do not interfere with each other before they converge, ensuring that the outer yarn is controlled before merging. After yarn breakage, it is easy to re-thread and check the trajectory when replacing the yarn.

[0031] During the operation of this device, although the broken wire monitoring and removal component has the function of automatically identifying and removing broken wires, when abnormal situations such as frequent broken wires, sensor failure, or broken wires entangled in the guide mechanism occur, manual intervention by the operator is still required to confirm the fault location, clean up the entangled wires, and perform necessary component maintenance operations.

[0032] The automatic wire-pulling unit 4 can perform rejection actions after a wire breakage occurs, including sucking, pulling out, and cutting. It is installed on the wire guide path, close to the physical area where the breakage point is located. The photoelectric sensor 54 is a detection sensor that detects whether the wire is broken in real time. The model of the photoelectric sensor 54 includes, but is not limited to, PZ-G41N, and can be used for transparent / fine wire detection.

[0033] This mechanism is a passive yarn feeding structure, consisting of a core yarn feeding shaft and an outer yarn feeding shaft, neither of which has a drive motor. The yarn movement is achieved by the downstream winding mechanism. The automatic yarn drawing assembly is used to automatically remove broken yarn fragments in a timely manner when they break during the transmission of the core yarn (such as spandex yarn), preventing them from remaining in the covering area and causing entanglement, jamming, or contamination.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] During operation, two symmetrically arranged outer wire reels 55 are installed on the top of the device, respectively mounted on the rotating shafts of the left and right supports, to provide double-strand outer wire. During the wrapping process, the outer wire is guided by the guide groove 64 in the guide plate 63 and then intertwined with the spandex yarn from the bottom core shaft 62 to form a wrapping yarn. The photoelectric sensor 54 detects a broken wire, and the automatic wire pulling unit 4 will complete the removal of the broken wire. When a large number of broken wire operations occur frequently, the specific outer wire reel 55 is disassembled, the folding plate 563 is pulled outward, and the connector 564 is simultaneously driven to separate from the mounting groove 2 on the surface of the working frame 1. At the same time, the spring 562 on the surface of the baffle 561 is squeezed, the screw rod 52 is rotated to separate the screw rod 52 from the threaded sleeve 57, and the moving plate 51, photoelectric sensor 54 and outer wire reel 55 are pulled up as a whole to disassemble and maintain them. When the device is completely finished, it is restored.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, 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 process, method, article, or apparatus.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
