Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to an anti-spinning probe device. Background Technology

[0002] In the production system of a chemical fiber texturing machine, the fiber detector is a key detection component that ensures the continuous operation of the fiber bundle. Its core function is to monitor the operating status of the fiber bundle in real time: during normal operation, the fiber bundle continuously passes through the detection area of ​​the fiber detector, and the fiber detector determines that the "fiber bundle is normal"; when the fiber bundle breaks, the fiber detector detects that the fiber bundle has stopped running and will immediately send a broken fiber signal to the fiber cutter of the texturing machine. After receiving the signal, the fiber cutter cuts the fiber in time to prevent the broken fiber from getting tangled on the rollers, heating box and other moving parts of the texturing machine, and prevent more serious consequences such as the whole machine cutting and equipment failure. However, a typical phenomenon called "illusionary wire cutting" exists in actual production, which seriously affects production continuity: Because the texturing machine typically operates at speeds of 300-800 m / min, the wire bundle is easily affected by factors such as airflow disturbances, roller vibration, and wire bundle tension fluctuations during high-speed transmission, resulting in a brief "wire throw" that causes it to temporarily detach from the wire detector's detection area. This "wire throw" is not a true wire breakage; the wire bundle remains intact, but the wire detector mistakenly interprets the "temporary disappearance of the wire bundle" as a wire breakage, thus sending an incorrect wire breakage signal to the wire cutter, causing the wire cutter to malfunction and cut the wire. Each instance of "illusionary wire cutting" causes production interruption, requiring operators to re-attach the wire and adjust the equipment, increasing labor intensity, generating wire waste, and reducing production efficiency and product qualification rate. To address the "illusionary wire cutting" problem, the most common solution in existing technologies is to install a semi-enclosed wire guide in front of the wire probe. This guide limits the wire bundle through a single-sided blocking structure, reducing the probability of wire breakage. However, this semi-enclosed structure has an inherent flaw—it does not completely enclose the wire bundle's movement space. When the wire bundle is thrown with great force or after multiple throws, it will still break off from the open side of the guide, failing to completely stop the wire breakage. Furthermore, after long-term use, the blocking component of the semi-enclosed guide is prone to deformation due to wire bundle friction, further reducing the limiting effect. The "illusionary wire cutting" phenomenon still occurs frequently, failing to fundamentally solve the problem. In summary, existing technologies lack a device that can completely prevent wire bundle ejection and ensure the accuracy of wire probe detection. This device needs to achieve fully enclosed limiting of the wire bundle to avoid false judgments triggered by wire ejection, while also ensuring convenient wire hanging without increasing operational complexity, and adapting to different models of wire probes to meet diverse production needs. Utility Model Content

[0003] In view of this, the purpose of this utility model is to propose an anti-spraying wire detector device, which blocks the wire bundle from being thrown at the source by designing a fully enclosed and easily operable wire pressing structure, and at the same time, with the aid of status monitoring, ensures that the wire detector only triggers wire cutting when the wire is actually broken.

[0004] To achieve the above objectives, this utility model provides an anti-throw wire detector device, which uses a wire presser to prevent the wire bundle from jumping out of the detector. The wire presser includes: A support base, on which a guide rod is mounted, the support base having a downward recess, the guide rod blocking the opening of the recess to form a closed channel; A tension spring is used to drive the guide rod to close the opening of the support seat recess.

[0005] Preferably, the guide rod has a crossbar and a bent rod. The crossbar is fixedly installed on one side of the support seat recess, and the bent rod is hinged in the middle to the other side of the support seat recess. The inner end of the bent rod has an upper right slope for the wire bundle to slide into the closed channel along its surface. The crossbar has a lower left slope corresponding to the lower slope. The outer end of the bent rod is flipped upward by a tension spring so that the two slopes fit together, and the contact point of the two slopes is on the path of the wire bundle passing through the guide rod.

[0006] Preferably, the support seat recess has a left seat and a right seat on both sides, the crossbar is fixedly installed on the right seat, the middle part of the bent rod is hinged to the left seat, the two ends of the tension spring are respectively connected to the outer end of the bent rod and the outer wall of the left seat, and the support seat recess is located between the left seat and the right seat.

[0007] Preferably, the support base is provided with a height adjustment component that drives the left and right seats to move up and down synchronously, in order to control the size of the closed channel to match the wire feeding port of the corresponding wire probe; The height adjustment assembly includes a limiting rod and a sleeve. The bottom of both the left and right seats is provided with a limiting rod and a sleeve, wherein the limiting rod is slidably connected to the support seat. The height adjustment assembly also includes a threaded rod and a drive rod. The threaded rods are rotatably mounted on the support base in two groups, and the two groups of threaded rods correspond to the sleeves of the left and right seats respectively. The sleeves are provided with nuts that form a threaded connection with the threaded rods. The drive rod is used to drive the two groups of threaded rods to rotate, thereby driving the sleeves to move the left and right seats longitudinally.

[0008] Preferably, the drive rod is a worm gear with one end hexagonal for screwing, and the threaded rod is provided with a worm wheel that meshes with the worm gear to form a transmission connection.

[0009] Preferably, a rubber pad is provided on the lower left slope of the crossbar to buffer the impact force when the inner end of the curved bar contacts the upper right slope.

[0010] Preferably, an inductive sensor is installed on the left side seat to determine whether the upper right slope of the inner end of the bent rod is in contact with the lower left slope of the crossbar to form a closed channel by detecting the outer end of the bent rod.

[0011] Preferably, the wire presser is located 1-2 cm in the direction of the wire bundle's travel from the wire feeding end to the wire probe.

[0012] The beneficial effects of this utility model are: 1. This utility model blocks the wire bundle from being thrown out at the source through a fully enclosed channel before the entrance. The inclined surface fit and secondary limiting further ensure that the wire bundle enters the detection area of ​​the wire probe stably. With the channel status monitoring of the sensor, the wire probe sends a signal only when the wire is actually broken, eliminating the "illusion of wire cutting". 2. It has strong versatility and adaptability. The height adjustment component covers the wire insertion height of the wire probe from 5-15mm, and is compatible with mainstream wire probe models on the market. There is no need to customize for different equipment, which reduces the purchase and replacement costs. 3. Easy to operate and maintain, the bending rod flip-type wire hanging does not require disassembly, the hexagonal end of the worm gear is compatible with universal tools, and height adjustment does not require professional skills.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0018] This utility model proposes an anti-wire-throwing wire probe device, such as... Figures 1 to 4 As shown, the specific structure is as follows: The wire presser, as a supporting component of the wire probe 1, consists of a support base 2 and a guide rod 3. The support base 2 is an integral load-bearing frame with a downward recessed notch on the side facing the detection area of ​​the wire probe 1. The position of the notch precisely corresponds to the wire bundle detection path of the wire probe 1, ensuring that the wire bundle can directly enter the detection area of ​​the wire probe 1 after passing through the notch without any offset gap. The guide rod 3 installed on the support base 2 has a shape that perfectly matches the notch, and can precisely seal the opening of the notch, so that the notch and the guide rod 3 together form a fully enclosed channel surrounding the wire bundle. The wire bundle is transmitted in the enclosed channel, completely isolating the disturbance of the wire bundle by airflow and vibration, preventing the wire bundle from leaving the channel and causing wire throwing, and fundamentally eliminating the cause of misjudgment by the wire probe 1. The function of the tension spring 4 is to ensure the continuous stability of the closed channel: one end is connected to the support base 2, and the other end is connected to the movable part of the guide rod 3. Under normal conditions, it provides continuous tension to drive the guide rod 3 to keep the notch sealed and ensure that the closed channel does not loosen. When it is necessary to hang wire, the operator only needs to push the movable part of the guide rod 3 in the direction of tension spring 4 to open the notch. After hanging the wire, release it, and the tension spring 4 will automatically rebound to reset and close the guide rod 3. The whole process does not require disassembly of parts, which takes into account both the anti-wire-throwing effect and the ease of operation. The guide rod 3 consists of a crossbar 31 (fixed part) and a bent rod 32 (movable part). The beveled surfaces of the two parts further enhance the anti-splashing and guiding accuracy. The crossbar 31 is fixed to one side of the recess in the support base 2, and its length covers the width of the recess to ensure that one side is completely covered. The middle part of the bent rod 32 is connected to the other side of the recess and can be rotated around the connection point. The inner end of the bent rod 32 (near the center of the notch) is a right-upper slope, and the inclination direction of this slope is consistent with the direction of the wire bundle's movement. When hanging the wire, the wire bundle can naturally slide into the closed channel along the slope without needing to be deliberately aligned, reducing operational errors. The corresponding position on the crossbar 31 is provided with a left-lower slope. The two slopes have the same inclination angle. When the tension spring 4 drives the bent rod 32 to flip, the two slopes can fit tightly together, preventing the wire bundle from coming out of the gap between the slopes. The contact point of the two slopes is directly above the detection path of the wire bundle passing through the wire probe 1. After the wire bundle passes through the closed channel and enters the wire probe 1, even if the wire bundle has a slight jump, it can be limited to prevent the wire bundle from leaving the detection area of ​​the wire probe 1, eliminating the illusion of wire cutting caused by "wire throwing". The support seat 2 has a notch on both sides forming a left seat 5 and a right seat 6, which symmetrically constitute a support frame. The crossbar 31 is fixed to the inside of the right seat 6; the middle of the bent rod 32 is connected to the inside of the left seat 5 in a flip-up manner. The two ends of the tension spring 4 are respectively connected to the outer end of the bent rod 32 and the outer wall of the left seat 5; the notch is located between the left and right seats 6 to ensure that the closed channel completely covers the filament path. To accommodate the detection area heights of different models of wire probes 1 (the wire insertion height varies by 5-15mm between different wire probes 1), the support base 2 is equipped with a height adjustment component 7, which drives the left and right side seats 6 to move up and down synchronously, so that the height of the closed channel is precisely aligned with the wire insertion height of the wire probe 1. If the channel and wire insertion height are misaligned, the wire bundle is prone to additional tension due to the path tilt, which increases the risk of wire ejection. Synchronous adjustment can avoid this problem. The adjustment component includes a limiting rod 71, a sleeve 72, a threaded rod 73, and a drive rod 74: one end of the limiting rod 71 is fixed to the bottom of the left side seat 5 and the right side seat 6, and the other end is inserted into the hole of the support base 2 to slide, limiting the direction of movement of the base; the top of the sleeve 72 is fixed to the bottom of the left side seat 5 and the right side seat 6, and a nut is provided inside the sleeve 72; the threaded rods 73 are installed on the support base 2 in two groups through bearings, and are threadedly engaged with the sleeves 72 at the bottom of the left side seat 5 and the right side seat 6; the drive rod 74 drives the two groups of threaded rods 73 to rotate synchronously, and drives the sleeves 72 up and down through thread transmission, so as to realize the synchronous lifting and lowering of the base. The drive rod 74 adopts a worm gear structure, with one end machined into a hexagonal shape to fit a universal hex wrench, allowing for adjustment without special tools; the threaded rod 73 has a worm wheel 731 at its lower part, which meshes with the worm to form a worm-worm wheel 731 transmission. This structure has self-locking properties, so the seat will not shift due to equipment vibration after adjustment, and the reduction ratio is large, enabling fine adjustment at the 0.1mm level, ensuring that the coaxiality error between the closed channel and the wire insertion port of the wire probe 1 is ≤0.3mm, further ensuring the stability of the wire bundle path. A rubber pad 311 is installed on the lower left slope of the crossbar 31. Made of high-temperature resistant (-20~80℃) and wear-resistant silicone, with a thickness of 0.3-0.5mm, it completely adheres to the slope and is flush with the surface. The rubber pad 311 serves two purposes: firstly, it buffers the impact force when the curved bar 32 is pressed against the slope, preventing wear and deformation of the metal slope and extending the component's lifespan; secondly, it utilizes the elasticity of the silicone to fill gaps in the slope's machining errors, ensuring a leak-proof seal and preventing filaments from being ejected from tiny gaps. An inductive sensor 8 is installed on the left side seat 5 and fixed to the outer wall by a bracket, with the detection end facing the outer end of the bent rod 32. For example, the detection distance is set to 0.8-1mm. When the inclined surfaces of the bent rod 32 fit together to form a closed channel, the sensor detects that the distance from the outer end of the bent rod 32 is ≤1mm, and determines that "the channel is closed normally". If the detection distance is >1mm, it means that the bent rod 32 is not completely closed (possibly due to the loosening of the tension spring 4 or foreign objects getting stuck). At this time, the sensor sends a "channel abnormality" signal to the texturing machine control system to remind the operator to check in time - to avoid wire throwing due to the unclosed channel, and further eliminate the triggering conditions for illusion wire cutting. The installation position of the wire presser has been verified and precisely calculated based on the wire throwing scenario: along the direction of the wire bundle from the feeding end to the wire detector 1, the wire presser is set 1-2cm in front of the entrance of the wire detector 1. This is the core position to block wire throwing, because the main scenario of wire throwing is that "the wire bundle deviates from the preset path due to disturbances during high-speed transmission before entering the detection area of ​​the wire detector 1". If the wire bundle is fully enclosed and limited before the entrance, wire throwing can be prevented from the source, avoiding misjudgment before the wire enters the wire detector 1.
