Abstract
Description
Technical Field
[0001] This utility model relates to the field of yarn equipment technology, and specifically to a yarn breakage detection device. Background Technology
[0002] Yarn is a continuous, slender body made from textile fibers. As an intermediate material connecting fibers and fabrics, it is widely used in the textile and apparel industry. Its definition encompasses both traditional staple yarn and filament yarn. Typically, staple fibers or filaments are arranged in a nearly parallel state and twisted along the axial direction to form a slender object with a certain strength and linear density. Currently, yarn is generally wound on a lead-out roller, and during use, the yarn is unwound from the lead-out roller. However, during the unwound process, we often encounter yarn breakage, which stops the unwound process and affects subsequent yarn processing. Therefore, a detection device that can detect whether the yarn has broken during the unwound process is what we need. Utility Model Content
[0003] The purpose of this invention is to solve the technical problem of providing a detection device that can detect whether yarn breaks during the unwinding process.
[0004] To solve the above-mentioned technical problems, the technical solution of this utility model for a wire breakage detection device is as follows:
[0005] The device includes a fixed plate and a lead-out roller, as well as a timer and a controller. A limiting shaft is connected above the fixed plate. A lead-out roller mounting plate is rotatably connected to the limiting shaft. A sleeve rod is connected above the lead-out roller mounting plate. The lead-out roller is placed on the sleeve rod and locked by a locking device. The locking device is threadedly connected to the sleeve rod. A mounting bracket is connected to the outer edge of the fixed plate. An infrared transmitter that emits infrared light downwards is connected to the upper end of the mounting bracket. An infrared receiver for receiving infrared light is connected directly below the infrared transmitter on the fixed plate. An arc-shaped baffle that can block infrared light is connected to the lead-out roller mounting plate. The lead-out roller mounting plate rotates itself to position the arc-shaped baffle between the infrared receiver and the infrared transmitter. The controller is connected to the timer, the infrared transmitter, and the infrared receiver.
[0006] Multiple vertical screws are connected below the roller mounting plate; the arc-shaped baffle has through holes corresponding to the vertical screws; the multiple vertical screws are threaded through the through holes corresponding to themselves and connected to locking nuts.
[0007] Six vertical screws are connected below the roller mounting plate, and there are six through holes on the corresponding arc-shaped baffle.
[0008] A rotating connecting sleeve is connected below the roller mounting plate; the rotating connecting sleeve is fitted onto the limiting shaft and is rotatably connected to the limiting shaft; a bearing is connected between the rotating connecting sleeve and the limiting shaft.
[0009] The limiting shaft has a limiting ring groove on its outer side that is coaxial with itself; the rotating connecting sleeve is threaded with a limiting bolt; the bottom end of the limiting bolt is hemispherical and passes through the rotating connecting sleeve and is inserted into the limiting ring groove.
[0010] A connecting plate is connected below the fixed plate; the connecting plate has a connecting hole.
[0011] A wire ring is also connected above the fixed plate.
[0012] The technical effect achieved by this utility model is as follows: This utility model determines whether the wire is broken by using an infrared receiver to receive infrared light and a timer to keep track of the timing. Specifically, the timer starts timing when the wire feeding roller begins to feed the wire, and the time is recorded until the infrared receiver continuously receives infrared light or fails to receive infrared light for a long time. The duration is 1. The total time from the wire feeding roller to the completion of wire feeding is generally similar. When the duration 1 is significantly shorter than the total time from the wire feeding roller to the completion of wire feeding, it can be determined that the wire feeding roller has broken during the feeding process. When the duration 1 is similar to the total time of wire feeding, it can be determined that the wire feeding roller has been completed and needs to be replaced. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.
[0020] See Figures 1 to 5 .
[0021] A wire breakage detection device includes a fixed disk 1 and a wire output roller 2, as well as a timer and a controller. A limiting shaft 3 is connected above the fixed disk 1, and a wire roller mounting disk 4 is rotatably connected to the limiting shaft 3. Specifically, a rotating connecting sleeve 21 is connected below the wire roller mounting disk 4. The rotating connecting sleeve 21 is fitted onto the limiting shaft 3 and rotatably connected to the limiting shaft 3. A bearing 22 is connected between the rotating connecting sleeve 21 and the limiting shaft 3. A limiting ring groove 31 coaxial with itself is opened on the outer side of the limiting shaft 3. A limiting bolt 32 is threadedly connected to the rotating connecting sleeve 21. The bottom end of the limiting bolt 32 is hemispherical and passes through the rotating connecting sleeve 21 and is inserted into the limiting ring groove 31. This invention prevents the rotating connecting sleeve 21 from detaching from the limiting shaft 3 through the cooperation of the limiting bolt 32 and the limiting ring groove 31, while the rotating connecting sleeve 21 can still rotate around the limiting shaft 3.
[0022] A sleeve rod 5 is connected above the roller mounting plate 4. The output roller 2 is placed on the sleeve rod 5 and locked by the locking member 6. The locking member 6 is threadedly connected to the sleeve rod 5. In fixing the output roller 2, the present invention places the output roller 2 on the sleeve rod 5 and then screws on the locking member 6 until the locking member 6 is tightened. At this time, the output roller 2 is locked between the roller mounting plate 4 and the locking member 6. When the output roller 2 outputs wire, the output roller 2 and the roller mounting plate 4 rotate together. Preferably, the roller mounting plate 4 is provided with anti-slip texture.
[0023] A mounting bracket 7 is connected to the outer edge of the fixed plate 1. An infrared transmitter 8 that emits infrared rays downward is connected to the upper end of the mounting bracket 7. An infrared receiver 9 for receiving infrared rays is connected directly below the infrared transmitter 8 of the fixed plate 1. The infrared transmitter 8 emits infrared rays downward and is received by the infrared receiver 9.
[0024] The roller mounting plate 4 is connected to an arc-shaped baffle 10 that can block infrared rays. Specifically, multiple vertical screws 11 are connected to the bottom of the roller mounting plate 4. The arc-shaped baffle 10 has through holes 12 corresponding to the vertical screws 11. The multiple vertical screws 11 pass through the through holes 12 corresponding to themselves and are threaded to a locking nut 13. Six vertical screws 11 are connected to the bottom of the roller mounting plate 4, and six through holes 12 are corresponding to the arc-shaped baffle 10. The arc-shaped baffle 10 of this utility model adopts the above-mentioned detachable connection structure for easy installation and replacement after damage. The roller mounting plate 4 rotates itself to position the arc-shaped baffle 10 between the infrared receiver 9 and the infrared transmitter 8, thereby blocking the infrared receiver 9 from receiving infrared rays. The controller is connected to the timer, the infrared transmitter 8 and the infrared receiver 9 respectively.
[0025] Preferably, a connecting plate 41 is connected below the fixing plate 1 of this utility model, and a connecting hole 42 is provided on the connecting plate 41; a wire ring 43 is also connected above the fixing plate 1.
[0026] Instructions for use: When using this utility model, the controller, timer, infrared transmitter 8, and infrared receiver 9 must first be powered on. When the wire feeding roller 2 feeds the wire, the wire feeding roller 2 will rotate together with the wire roller mounting plate 4, while the arc-shaped baffle 10 will continuously block the infrared rays emitted by the infrared transmitter 8, causing the infrared receiver 9 to receive the infrared rays intermittently. When the wire roller mounting plate 4 stops rotating, the infrared receiver 9 will either continuously receive infrared rays or continuously fail to receive infrared rays. When the infrared receiver 9 detects the above signal (i.e., the infrared receiver 9 will either continuously receive infrared rays or continuously fail to receive infrared rays), there are generally two situations: one, wire breakage; two, all the wire on the wire feeding roller 2 has been fed. Since the wire feeding speed of the wire feeding roller 2 is generally uniform and the total length of the wire on the wire feeding roller 2 is generally similar, the total time for the wire feeding roller 2 to feed the wire is generally similar.
[0027] When the wire feeder roller 2 feeds the wire, a timer starts counting. When the infrared receiver 9 continuously receives infrared light or fails to receive infrared light for a long time, the timer stops counting and obtains a duration of 1. When the duration of 1 is significantly shorter than the total time required for the wire feeder roller 2 to feed the wire, it can be determined that the wire feeder roller 2 has broken. When the duration of 1 is close to the total time required for the wire feeder roller 2 to feed the wire, it can be determined that the wire feeder roller 2 has finished feeding the wire and needs to be replaced with a new wire feeder roller 2. Therefore, the controller of this utility model can determine whether the wire on the wire feeder roller 2 has broken by comparing the duration of 1 obtained by the timer with the preset total time required for the wire feeder roller 2 to feed the wire, and then provide feedback.
