Description

Technical Field

[0001] This utility model relates to the field of chemical fiber processing technology, and in particular to a tension balancing device for winding chemical fiber filaments. Background Technology

[0002] In existing technologies, during the production and processing of synthetic fiber filaments, it is necessary to tension the filaments during transport to maintain tension balance. Current tensioning devices do generate tension on the filaments, but they struggle to maintain stable tension balance and are unable to promptly alert to changes in tension, resulting in poor winding performance. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides a tension balancing device for winding chemical fiber filaments. This device can tension the chemical fiber filaments and maintain stable tension, and will issue an alarm in case of filament breakage or other issues.

[0004] This utility model discloses a tension balancing device for winding chemical fiber filaments, including a support, a rotating rod and a tension rod. One end of the rotating rod is rotatably connected to the support, and the other end of the rotating rod is fixedly provided with a tension rod. The tension rod and the rotating rod form an angle and extend outward, and the angle range is 60-90°. A yarn guide ring is fixedly provided at the end of the tension rod.

[0005] A positioning ring is fixedly installed in the middle of the rotating rod, and a torsion spring is sleeved on the rotating rod between the positioning ring and the support. The two ends of the torsion spring are fixedly connected to the positioning ring and the support, respectively.

[0006] A protrusion is fixed on the positioning ring, and a crank plate is connected to the support. One end of the crank plate extends to the protrusion. A battery and an alarm are installed on the crank plate. A cavity is provided on the crank plate corresponding to the protrusion. A micro switch is installed in the cavity. The trigger point of the micro switch is located outside the cavity of the crank plate and corresponds to the protrusion.

[0007] The battery is electrically connected to a micro switch, and the micro switch is electrically connected to an alarm.

[0008] A recessed groove is provided on the side wall of the support. A sliding rod is provided in the groove along the length of the groove. The end of the crank plate extends into the groove. A guide hole is provided on the crank plate in the groove corresponding to the sliding rod. The sliding rod passes through the guide hole. The crank plate slides in the groove. A compression spring is sleeved on the sliding rod in the groove at the end away from the rotating rod. The two ends of the compression spring abut against the end of the groove and the crank plate, respectively.

[0009] A pinch block is fixedly installed on one side of the turntable.

[0010] Several ear plates are evenly spaced on the side of the support, and mounting holes are provided on the ear plates.

[0011] The tension balancing device for winding chemical fiber filaments obtained by this invention has the following beneficial effects:

[0012] By incorporating a protrusion, a micro switch, and a crank plate, the chemical fiber filaments pass through the guide ring during operation, generating downward tension on the guide ring. This keeps the tension rod in a downward tilted state. At this time, the torsion spring generates a certain torque to maintain balance. Whenever a chemical fiber filament breaks, the force of the torsion spring can reset the tension rod, which then abuts against the lower side of the crank plate end via the protrusion. The protrusion can also press against the trigger end of the micro switch, activating the alarm and emitting an alarm sound to remind personnel to handle the broken filament situation. This can prevent the delay in detection from affecting winding efficiency.

[0013] With the spring and groove in place, after each use of the tensioning device, the crank plate can be moved backward by applying force to displace the protrusion, thus releasing the tension rod. The force of the torsion spring causes the tension rod to rotate several times and stop to relieve the force. At this time, the torsion spring is in a relaxed state, which can avoid the torsion spring being in a tense state during non-operation periods, and indirectly improve the service life of the torsion spring.

[0017] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0018] Example 1:

[0019] like Figures 1-3 As shown, this utility model discloses a tension balancing device for winding chemical fiber filaments, including a support 3, a rotating rod 2 and a tension rod 1. One end of the rotating rod 2 is rotatably connected to the support 3, and the other end of the rotating rod 2 is fixedly provided with the tension rod 1. The tension rod 1 and the rotating rod 2 form an angle and extend outward, and the angle range is 60-90°. The end of the tension rod 1 is fixedly provided with a yarn guide ring 11.

[0020] A positioning ring 21 is fixedly installed in the middle part of the rotating rod 2. A torsion spring 23 is sleeved on the rotating rod 2 between the positioning ring 21 and the support 3. The two ends of the torsion spring 23 are fixedly connected to the positioning ring 21 and the support 3 respectively.

[0021] A protrusion 24 is fixed on the positioning ring 21, and a crank plate 4 is connected to the support 3. One end of the crank plate 4 extends to the protrusion 24. A battery 42 and an alarm 43 are provided on the crank plate 4. A cavity is provided on the crank plate 4 at the position corresponding to the protrusion 24. A micro switch 44 is provided in the cavity. The trigger point of the micro switch 44 is located outside the cavity of the crank plate 4 and corresponds to the protrusion 24.

[0022] The battery 42 is electrically connected to the micro switch 44, and the micro switch 44 is electrically connected to the alarm 43.

[0023] Support 3 is a fixed base used to connect to the frame of the winding equipment. During normal use, support 3 is fixed to the side of the running yarn path before the chemical fiber filament is wound, and located above the chemical fiber filament. The chemical fiber filament passes through the yarn guide ring 11 at the end of the tension rod 1. Since the rotating rod 2 and support 3 are rotatably connected, a bearing can be installed inside support 3, and the end of the rotating rod 2 is connected to the bearing, thus allowing the rotating rod 2 to rotate freely relative to support 3. Tension rod 1 is fixed to the end of the rotating rod 2, and tension rod 1 can rotate freely with the rotating rod 2. The end of tension rod 1 extends to the corresponding chemical fiber filament's yarn path, and a yarn guide ring 11 is provided at the end, through which the chemical fiber filament passes. Meanwhile, the torsion spring 23 on the rotating rod 2 is fixed at both ends to the positioning ring 21 and the support 3. Therefore, in its natural state, the guide ring 11 is positioned above the chemical fiber filament. When the chemical fiber filament passes through the guide ring 11, it generates a downward tension on the guide ring 11, while the torsion spring 23 generates a torque. During normal winding, the tension remains balanced. The downward pulling force of the chemical fiber filament on the guide ring 11 is balanced by the torque of the torsion spring 23.

[0024] The optimal state is when the rotating rod 2 and the tension rod 1 form a 90° angle.

[0025] A crank plate 4 is installed on the support 3, and a protrusion 24 is installed on the positioning ring 21. When the tension rod 1 maintains tension balance, the crank plate 4 is located above the protrusion 24. That is, when the rotating rod 2, positioning ring 21, and protrusion 24 rotate with the torque of the torsion spring 23, the positioning hole will contact the crank plate 4. At the same time, a battery 42, an alarm 43, and a micro switch 44 are installed on the crank plate 4. The three are electrically connected, and the micro switch 44 is set downward and corresponds to the protrusion 24. During actual use and operation, the chemical fiber filaments pass through the yarn guide ring 11, generating a downward pulling force on the yarn guide ring 11 and the tension rod 1, causing the torsion spring 23 to generate torque, thus maintaining the balance of forces on the tension rod 1. There is a certain gap between the protrusion 24 and the micro switch 44 on the crank plate 4. Once the chemical fiber filament breaks, the force acting on the yarn guide ring 11 disappears. At this time, under the torsion of the torsion spring 23, the rotating rod 2 and tension rod 1 rotate, and the protrusion 24 also rotates with the rotating rod 2 and touches the micro switch 44. The micro switch 44 triggers the alarm 43 to sound an alarm, reminding the worker to deal with the broken filament problem, so as to ensure the stability and reliability of the chemical fiber filament winding and improve the winding efficiency.

[0026] The battery 42, micro switch 44, alarm 43, etc. are all commercially available products, and their circuit connections are all conventional methods in this field, so they will not be described in detail here.

[0027] A recessed groove 52 is provided on the side wall of the support 3. A sliding rod 5 is provided in the groove 52 along its length. The end of the crank plate 4 extends into the groove 52. A guide hole is provided on the crank plate 4 in the groove 52 corresponding to the sliding rod 5. The sliding rod 5 passes through the guide hole, and the crank plate 4 slides in the groove 52. A compression spring 51 is sleeved on the sliding rod 5 in the groove 52 at the end away from the rotating rod 2. The two ends of the compression spring 51 abut against the end of the groove 52 and the crank plate 4, respectively. The groove 52 is provided on the support 3, and the length of the groove 52 is consistent with the axis of the rotating rod 2. The end of the crank plate 4 is slidably connected to the groove 52, and the sliding rod 5 is provided in the groove 52, making the connection of the crank plate 4 in the groove 52 more secure and the sliding more stable. Simultaneously, a compression spring 51 is fitted onto the slide rod 5 within the slide groove 52, allowing the compression spring 51 to push the crank plate 4 to one end of the slide groove 52 closer to the rotating rod 2. At this time, the micro switch 44 on the crank plate 4 corresponds to the protrusion 24. When the device is not in operation, the crank plate 4 can be pushed to overcome the pressure of the compression spring 51 and slide within the slide groove 52, causing the crank plate 4 and the protrusion 24 to be completely misaligned. Under the action of the torsion spring 23, the rotating rod 2 rotates, and there is no interference between the protrusion 24 and the crank plate 4, thus releasing the torque of the torsion spring 23. Therefore, during non-operation periods, the torsion spring 23 can be kept in a naturally relaxed state, extending its service life and stability.

[0028] A pinch block 41 is fixedly installed on one side of the crank plate 4. The pinch block 41 on the crank plate 4 makes it easier to apply pushing force when pushing the crank plate 4 to slide, making the operation more convenient.

[0029] A guide hole 45 can be provided inside the bend plate 4 to facilitate the connection of wires between the battery 42, the alarm and the micro switch 44.

[0030] Several ear plates 31 are evenly spaced on the side of the support 3, and mounting holes are provided on the ear plates 31.

[0031] The number of ear plates 31 provided on the support 3 can be three or four, depending on the actual needs. The ear plates 31 are integrated with the support 3, which facilitates the fixing of the support 3 on the frame.
