Description

Technical Field

[0001] This application relates to the field of detection structure technology, and in particular to a yarn breakage detection structure for network yarn. Background Technology

[0002] Network yarn is a type of yarn that is produced by twisting pre-oriented yarn or stretching textured yarn with high-pressure oxygen flow, causing the monofilaments to intertwine and form periodic network knots. This structure gives network yarn unique physical properties, such as enhanced strength and stability.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: In the process of producing yarn, two rolls of monofilament need to be transported and intertwined using equipment. During the transport of the monofilament, when the pulling force is large, the monofilament is prone to breakage, which seriously affects production efficiency. Utility Model Content

[0004] To address the issue of monofilament breakage easily occurring under high pulling forces, which affects production efficiency, this application provides a yarn breakage detection structure for network yarns.

[0005] The yarn breakage detection structure for network yarn provided in this application adopts the following technical solution:

[0006] A yarn breakage detection structure for network yarn includes a support assembly, a threading assembly, and a detection assembly. The support assembly includes a base and a column fixed to the upper surface of the base. The support assembly also includes a vertical plate slidably disposed on the upper surface of the column and a horizontal plate fixed to the upper surface of the vertical plate.

[0007] The threading assembly is used to transport the network yarn monofilament. The threading assembly includes two strip frames symmetrically fixed on the upper surface of the horizontal plate, and an L-shaped plate fixed on the surface of the vertical plate and corresponding to the two strip frames. The surface of the strip frames has two symmetrical first threading holes, and the surface of the L-shaped plate has two second threading holes corresponding to the first threading holes.

[0008] The detection component is used to detect yarn breakage during the conveying of network yarn monofilaments. The detection component includes a fixed cylinder fixed to the surface of the vertical plate and a rotating shaft fixed to the inner wall of the fixed cylinder. The surface of the fixed cylinder has two symmetrical arc-shaped openings. The surface of the rotating shaft is rotatably provided with two rotating blocks that are slidably connected to the inner walls of the two arc-shaped openings respectively. The surface of the rotating blocks is fixed with connecting rods, and the top of the connecting rods is fixed with a wire guide ring. The detection component also includes a contact switch fixed to the inner wall of the arc-shaped opening and an alarm fixed to the end of the fixed cylinder. The contact switch and the alarm are electrically connected through wires.

[0009] By adopting the above technical solution, the yarn breakage detection structure of the network yarn has a highly efficient and accurate yarn breakage detection function, which can monitor the status of the network yarn monofilaments in real time during the conveying process, ensuring the continuity and stability of the production process. The support component, through the combination of base, column, vertical plate and horizontal plate, provides a stable installation foundation for the yarn feeding component and detection component. At the same time, the sliding vertical plate improves the adjustment flexibility of the overall structure and adapts to different conveying requirements. The yarn feeding component forms a stable yarn feeding channel through the strip frame and L-shaped plate. The first yarn feeding hole on the strip frame and the second yarn feeding hole on the L-shaped plate are symmetrically corresponding, which can effectively limit the conveying path of the monofilament and avoid the detection accuracy being affected by yarn swaying. The detection component constructs a stable detection mechanism through the fixed cylinder and rotating shaft. The rotating block on the rotating shaft achieves flexible detection by sliding connection with the inner wall of the arc-shaped opening. The combination design of the connecting rod and the yarn feeding ring further enhances the accuracy of the detection. During the detection process, when a single filament breaks or shifts, the rotating block drives the connecting rod to trigger the contact switch. The contact switch is electrically connected to the alarm via a wire, immediately activating the alarm to issue an audible and visual alarm, promptly reminding the operator to handle the problem. The entire system, through a stable conveyor channel and sensitive detection components, achieves a highly efficient yarn breakage detection function, significantly improving the efficiency and reliability of network yarn conveying and detection, reducing the impact of yarn breakage on the production process, and ensuring the efficient operation of the production line.

[0010] Preferably, a sleeve is slidably provided on the outer surface of the column, and a threaded hole is opened on the surface of the sleeve, with a locking bolt threadedly connected to the inner wall of the threaded hole.

[0011] By adopting the above technical solution, the height of the sleeve can be easily adjusted by tightening the bolts.

[0012] Preferably, the upper surface of the horizontal plate has two first mounting holes, and the inner wall of the first mounting holes is slidably connected with an internal hexagon bolt, and the upper surface of the vertical plate has a first threaded groove adapted to the internal hexagon bolt.

[0013] By adopting the above technical solution, the internal hex bolts facilitate the quick installation and disassembly of the horizontal and vertical plates.

[0014] Preferably, the surface of the L-shaped plate is provided with a second mounting hole, and the inner wall of the second mounting hole is provided with a first mounting bolt, and the surface of the vertical plate is provided with a second threaded groove that matches the first mounting bolt.

[0015] By adopting the above technical solution, the first mounting bolt facilitates the quick installation and removal of the L-shaped plate.

[0016] Preferably, a mounting plate is fixedly provided on the outer surface of the end of the fixed cylinder, and two third mounting holes are opened on the surface of the mounting plate. A second mounting bolt is provided on the inner wall of the third mounting hole, and a third threaded groove adapted to the second mounting bolt is opened on the outer surface of the vertical plate.

[0017] By adopting the above technical solution and setting a second mounting bolt, it is convenient to quickly install and disassemble the detection component.

[0018] Preferably, two symmetrical torsion springs are fixedly provided on the surface of the rotating shaft, and one end of the torsion spring is fixedly connected to the inner wall of the fixed cylinder, and the other end of the torsion spring is fixedly connected to the surface of the rotating block.

[0019] By adopting the above technical solution and setting a torsion spring, the rotating block can be automatically rotated when the yarn breaks.

[0020] Preferably, the network yarn monofilament passes sequentially through two first thread holes on the strip frame, through a thread loop, and then through a second thread hole.

[0021] By adopting the above technical solution, the network yarn monofilaments pass sequentially through the two first threading holes, the threading ring, and the second threading hole on the strip frame, forming a stable conveying path. This effectively avoids shaking or deviation during the monofilament conveying process, ensuring the sensitivity and accuracy of the detection components. At the same time, when a yarn breakage occurs, the movement of the threading ring quickly triggers the contact switch, activating the alarm and promptly reminding the operator to handle the situation, thereby improving the conveying stability and the reliability of yarn breakage detection.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application, by setting up a yarn feeding assembly and a detection assembly, ensures that when a single filament breaks, it can no longer support the yarn feeding ring. At this time, under the action of the torsion spring, the rotating block rotates downward and contacts the contact switch. The contact switch automatically controls the alarm to sound an alarm, reminding personnel that a yarn breakage has occurred. This is highly practical.

[0024] 2. By setting up a support component, the height of the detection structure can be adjusted by locking bolts, thereby enabling the detection of network yarn monofilaments under different conveying conditions. At the same time, the vertical plate and horizontal plate, the vertical plate and L-shaped plate, and the fixed cylinder and vertical plate in the detection structure can be quickly disassembled, which facilitates the rapid assembly of the detection structure.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0032] This embodiment discloses a yarn breakage detection structure for network yarn.

[0033] Example 1

[0034] Reference Figures 1 to 5 A yarn breakage detection structure for network yarn includes a support component 100, a threading component 200, and a detection component 300. The support component 100 includes a base 101 and a column 102 fixed on the upper surface of the base 101. The support component 100 also includes a vertical plate 103 slidably disposed on the upper surface of the column 102 and a horizontal plate 104 fixed on the upper surface of the vertical plate 103.

[0035] Reference Figure 3 A sleeve 105 is slidably provided on the outer surface of the column 102, and a threaded hole is provided on the surface of the sleeve 105. A locking bolt 106 is threadedly connected to the inner wall of the threaded hole. The height of the sleeve 105 can be easily adjusted by the locking bolt 106.

[0036] Reference Figure 3The upper surface of the horizontal plate 104 has two first mounting holes, and the inner wall of the first mounting holes is slidably connected with an internal hexagon bolt. The upper surface of the vertical plate 103 has a first threaded groove that matches the internal hexagon bolt. By setting an internal hexagon bolt, it is convenient to quickly install and disassemble the horizontal plate 104 and the vertical plate 103.

[0037] In this embodiment, the support component 100 can adjust the height of the detection structure by means of the locking bolt 106, thereby enabling the detection of network yarn monofilaments under different conveying conditions.

[0038] Example 2

[0039] Based on Example 1, the difference between this example and Example 1 is that...

[0040] A yarn breakage detection structure for network yarn further includes a yarn feeding assembly 200 for conveying the network yarn monofilaments. The yarn feeding assembly 200 includes two strip frames 201 symmetrically fixed to the upper surface of a horizontal plate 104, and an L-shaped plate 202 fixed to the surface of a vertical plate 103 and corresponding to the two strip frames 201. The surface of the strip frames 201 has two symmetrical first yarn feeding holes 203, and the surface of the L-shaped plate 202 has two second yarn feeding holes 204 corresponding to the first yarn feeding holes 203. The symmetrically arranged strip frames 201 in the yarn feeding assembly 200 In conjunction with the L-shaped plate 202, a stable monofilament conveying path for the network yarn is formed. The corresponding design of the first thread hole 203 and the second thread hole 204 can effectively limit the conveying position of the monofilament, prevent conveying abnormalities or detection errors caused by shaking or deviation, and ensure the positioning and constraint of the monofilament in different directions. The combination of the strip frame and the L-shaped plate not only improves the stability of the threading, but also provides higher accuracy and reliability for yarn breakage detection, effectively reducing production stoppages and resource waste caused by yarn breakage or disorder, and ensuring the efficient operation of the yarn conveying and detection process.

[0041] Reference Figure 1 In a preferred embodiment, the surface of the L-shaped plate 202 is provided with a second mounting hole, and the inner wall of the second mounting hole is provided with a first mounting bolt. The surface of the vertical plate 103 is provided with a second threaded groove that matches the first mounting bolt.

[0042] By setting the first mounting bolt, it is easy to quickly install and remove the L-shaped plate 202.

[0043] The detection component 300 is used to detect yarn breakage during the conveying of monofilaments in a network yarn. The detection component 300 includes a fixed cylinder 301 fixed to the surface of the vertical plate 103, and a rotating shaft 302 fixed to the inner wall of the fixed cylinder 301. Two symmetrical arc-shaped openings 303 are formed on the surface of the fixed cylinder 301. Two rotating blocks 304 are rotatably mounted on the surface of the rotating shaft 302, each slidably connected to the inner wall of one of the arc-shaped openings 303. A connecting rod 305 is fixed to the surface of each rotating block 304, and a wire guide ring 306 is fixed to the top of the connecting rod 305. The detection component 300 also includes a contact switch 307 fixed to the inner wall of the arc-shaped opening 303, and an alarm 308 fixed to the end of the fixed cylinder 301. The contact switch 307 and the alarm 308 are electrically connected via a wire. Next, the detection component 300, through the flexible cooperation of the fixed cylinder 301, the rotating shaft 302 and its rotating block 304, realizes real-time monitoring of the single filament breakage status of the network yarn. The sliding connection between the arc-shaped opening 303 and the rotating block 304 ensures the sensitivity and stability of the detection. The fixed design of the connecting rod 305 and the thread guide ring 306 ensures that the yarn is always within the detection range. When a yarn breakage or abnormality occurs, the rotating block 304 drives the connecting rod 305 to trigger the contact switch 307 in the arc-shaped opening 303. The contact switch 307 quickly activates the alarm 308 to issue an alarm, promptly reminding the operator to handle the problem, thereby improving the accuracy and response speed of yarn breakage detection, significantly reducing production delays and quality losses caused by yarn breakage, and ensuring the efficiency and reliability of the yarn conveying process.

[0044] Reference Figure 2 In a preferred embodiment, a mounting plate 309 is fixedly provided on the outer surface of the end of the fixed cylinder 301, and two third mounting holes are provided on the surface of the mounting plate 309. The inner wall of the third mounting hole is provided with a second mounting bolt, and the outer surface of the vertical plate 103 is provided with a third threaded groove that matches the second mounting bolt. By providing the second mounting bolt, it is convenient to quickly install and disassemble the detection component 300.

[0045] Reference Figure 5 Two symmetrical torsion springs 3010 are fixedly provided on the surface of the rotating shaft 302. One end of the torsion spring 3010 is fixedly connected to the inner wall of the fixed cylinder 301, and the other end of the torsion spring 3010 is fixedly connected to the surface of the rotating block 304. By setting the torsion spring 3010, the rotating block 304 can be automatically rotated when the yarn breaks.

[0046] Reference Figure 1The network yarn monofilaments sequentially pass through the two first threading holes 203 on the strip frame 201, then through the threading ring 306, and finally through the second threading hole 204. By sequentially passing through the two first threading holes 203, the threading ring 306, and the second threading hole 204 on the strip frame 201, a stable and precise conveying path is formed. This effectively prevents the monofilaments from shaking or shifting during the conveying process, ensuring the stability and positional accuracy of the yarn conveying. At the same time, it provides a reliable positioning basis for the yarn breakage monitoring of the detection component. When a yarn breakage occurs, the threading ring 306 is triggered in time to achieve efficient and accurate yarn breakage detection and alarm reminder, thereby improving the overall efficiency of conveying and detection.

[0047] In this embodiment, by setting up the wiring assembly 200 and the detection assembly 300, when a single filament breaks, the contact switch 307 automatically controls the alarm 308 to sound an alarm, reminding personnel that a yarn breakage has occurred, which is highly practical.

[0048] The working principle of a yarn breakage detection structure for network yarn according to an embodiment of this application is as follows: During the production of network yarn, when two network yarn monofilaments are being conveyed, the monofilaments pass through two first thread guide holes 203, thread guide rings 306 and second thread guide holes 204 in sequence. At this time, under the action of the monofilament tension, the thread guide rings 306 move upward and are fixed. When a monofilament breaks, it can no longer support the thread guide rings 306. At this time, under the action of the torsion spring 3010, the rotating block 304 rotates downward and contacts the contact switch 307. The contact switch 307 automatically controls the alarm 308 to sound an alarm, reminding personnel that a yarn breakage has occurred. It is highly practical, and the height of the detection structure can be adjusted according to the actual situation by tightening the locking bolts 106, thereby enabling the detection of network yarn monofilaments under different conveying conditions.

[0049] The technical advantages of the yarn breakage detection structure for network yarn in this application embodiment are as follows:

[0050] 1. Height Adjustability: Through the design of the locking bolt 106 and sliding sleeve 105 in the support component 100, the height of the device can be flexibly adjusted according to actual production needs, adapting to different conveying conditions and improving detection adaptability and ease of operation.

[0051] 2. Conveying stability: The strip frame 201 and L-shaped plate 202 in the yarn feeding assembly 200 cooperate to form a stable monofilament conveying path through the precise positioning of the first yarn feeding hole 203 and the second yarn feeding hole 204, effectively preventing swaying or deviation during yarn conveying and ensuring conveying accuracy and stability.

[0052] 3. High detection sensitivity: The detection component 300 utilizes the linkage of the rotating shaft 302, the rotating block 304 and the connecting rod 305, combined with the arc-shaped opening 303 and the contact switch 307, to achieve rapid sensing and timely alarm when the yarn is broken, significantly improving the detection sensitivity and response speed.

[0053] 4. Automatic reset function: The torsion spring 3010 drives the rotating block 304 to reset in the event of a yarn breakage, ensuring that the detection component is always in a monitorable state and improving the continuity and reliability of the device operation.

[0054] 5. Comprehensive alarm function: The detection component 300 has a built-in contact switch 307 and alarm 308, which can immediately issue an audible and visual alarm signal when yarn breakage occurs, promptly reminding operators to handle the situation and effectively reducing production delays and yarn waste.

[0055] 6. Ease of installation: The support component 100 and the detection component 300 adopt a modular design and are connected by mounting holes and bolts, which can be quickly disassembled and assembled, facilitating equipment maintenance and structural adjustment.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
