Description

Technical Field

[0001] This utility model relates to the field of glass fiber weaving technology, and in particular to a rotating stop device for glass fiber weaving. Background Technology

[0002] During the warp knitting process of glass fiber, the warp yarns need to be continuously conveyed with stable tension. If yarn breaks due to material defects, tension fluctuations, or equipment vibrations, failure to handle it in time will cause the broken yarns to become entangled with the warp knitting take-up rollers due to inertia, resulting in a large amount of yarn waste. Moreover, the broken yarn locations are hidden, increasing the difficulty of rework and seriously affecting production efficiency.

[0003] Existing rotary warp-stopping devices mostly rely on comb teeth to comb the warp yarns and brushes to capture broken yarns, triggering a stop signal through a mechanical contact structure. However, broken yarns are easily swept away by airflow or disordered equipment movement, resulting in a low success rate of brush capture. In view of this, this application proposes a rotary warp-stopping device for glass fiber weaving. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rotating stop device for glass fiber weaving.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rotating stop device for glass fiber weaving includes two support plates, both of which are rotatably connected to a rotating shaft. Each support plate is rotatably connected to the rotating shaft via a bearing. A drive mechanism is mounted on the outer side of one of the support plates, driving the rotating shaft to rotate. A cavity is formed inside the rotating shaft, and multiple micro-holes are equidistantly formed on the outer circumference of the rotating shaft, each micro-hole communicating with the cavity. A negative pressure component is mounted on the outer side of one of the support plates, and the negative pressure component is connected to the rotating shaft. A trigger component and a stop-weave sensing component are respectively mounted on the outer side of the rotating shaft. A fixed base is fixedly mounted on the outer side of the rotating shaft, and multiple bristles are symmetrically mounted on the top surface of the fixed base. Multiple comb teeth are linearly and equidistantly mounted on the top surface of the fixed base.

[0007] Preferably, the negative pressure assembly includes a negative pressure fan, which is fixedly installed on the outside of the corresponding support plate. A connecting pipe is fixed to and connected to the outside of the negative pressure fan, and the other end of the connecting pipe is connected to the rotating shaft through a rotary joint.

[0008] Preferably, the triggering component includes a first rotating shaft, which is fixedly installed on the outside of the rotating shaft. A second rotating shaft is rotatably connected to the outside of the rotating shaft, and the first and second rotating shafts are located on the same axis. A first mounting plate and a second mounting plate are respectively installed on the top surfaces of the first and second rotating shafts. A pull wire is installed on the outer side of the first and second mounting plates, with one end of the pull wire installed at the center of the bearing and the other end of the pull wire eccentrically set with respect to the center of the second mounting plate. A torsion spring is installed between the outer side of the second rotating shaft and the rotating shaft.

[0009] Preferably, the stop-motion sensing component includes an L-shaped plate, which is fixedly installed on the outside of the rotating shaft. A laser emitter is installed on the bottom surface of the L-shaped plate, and a laser receiver is installed on the top surface of the second mounting plate. The laser receiver is eccentrically positioned with respect to the second mounting plate.

[0010] Preferably, the drive mechanism includes a fixed frame, which is fixedly installed on the outside of the corresponding support plate. A drive motor is fixedly installed on the outside of the fixed frame. A drive gear is installed on the outside of the output shaft of the drive motor. A driven gear is installed on the outside of the rotating shaft, and the driven gear meshes with the drive gear.

[0011] Preferably, the drive motor is a conical rotor motor, and the pitch circle diameter of the drive gear is smaller than that of the driven gear.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model achieves efficient combing of warp yarns and precise capture of broken yarns through a drive mechanism, a negative pressure component, a rotating shaft, a cavity, micropores, bristles, and comb teeth. The drive mechanism drives the rotating shaft to rotate stably, the comb teeth comb the warp yarns to prevent tangling, the negative pressure component creates a negative pressure zone in the micropores to constrain the disorderly movement of broken yarns, and the rotating bristles quickly wrap around and capture broken yarns, reducing yarn waste and improving the efficiency of broken yarn processing.

[0014] 2. This utility model achieves sensitive detection of yarn breakage and timely braking of the equipment through devices such as trigger components and warp stop sensing components. When the broken yarn wraps around and pulls the pull wire, it causes the trigger component to move, which drives the laser receiver and laser emitter to change position. The warp stop sensing component quickly identifies the signal and transmits it to the control system, thereby achieving timely braking of the drive motor and the external winding roller, improving the sensing sensitivity and equipment response speed.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] This utility model provides a technical solution: such as Figure 1-4 As shown, a rotating stop device for glass fiber weaving includes two support plates 1, both support plates 1 are rotatably connected to a rotating shaft 2, and each support plate 1 is rotatably connected to the rotating shaft 2 through a bearing 8. A drive mechanism is installed on the outer side of one of the support plates 1, and the drive mechanism drives the rotating shaft 2 to rotate. A cavity 7 is opened inside the rotating shaft 2, and multiple micro holes 3 are equidistantly opened on the outer circumference of the rotating shaft 2, and each micro hole 3 is connected to the cavity 7. A negative pressure component is installed on the outer side of one of the support plates 1, and the negative pressure component is connected to the rotating shaft 2. A trigger component and a stop sensing component are respectively installed on the outer side of the rotating shaft 2. A fixed seat 9 is fixedly installed on the outer side of the rotating shaft 2. Multiple bristles 10 are symmetrically installed on the top surface of the fixed seat 9, and multiple comb teeth 11 are linearly equidistantly installed on the top surface of the fixed seat 9.

[0022] It should be noted that the comb teeth 11 can comb the glass fiber, while the bristles 10 can wrap the broken fibers. The fibers wrapped around the outside of the rotating shaft 2 drive the trigger component and the stop-warp sensing component, which can brake the external winding device in time. Furthermore, through the setting of the negative pressure component, cavity 7, and micropores 3, negative pressure can be generated through the micropores 3 to adsorb the disorderly floating broken yarn in time, reduce the situation of the broken yarn swinging in a large-scale disorderly manner, and thus improve the success rate of winding.

[0023] Furthermore, the negative pressure assembly includes a negative pressure fan 4, which is fixedly installed on the outside of the corresponding support plate 1. A connecting pipe 5 is fixed and connected to the outside of the negative pressure fan 4, and the other end of the connecting pipe 5 is connected to the rotating shaft 2 through a rotary joint 6. The normal rotation of the rotating shaft 2 can be ensured through the rotary joint 6.

[0024] Furthermore, the triggering component includes a first rotating shaft 17, which is fixedly installed on the outside of the rotating shaft 2. A second rotating shaft 23 is rotatably connected to the outside of the rotating shaft 2. The first rotating shaft 17 and the second rotating shaft 23 are located on the same axis. A first mounting plate 18 and a second mounting plate 19 are respectively installed on the top surfaces of the first rotating shaft 17 and the second rotating shaft 23. A pull wire 12 is installed on the outer side of the first mounting plate 18 and the second mounting plate 19. One end of the pull wire 12 is installed at the center of the bearing 8, and the other end of the pull wire 12 is eccentrically set with respect to the center of the second mounting plate 19. A torsion spring 24 is installed between the second rotating shaft 23 and the outer side of the rotating shaft 2. The torsion spring 24 is used for the reset of the second rotating shaft 23.

[0025] Furthermore, the stop-warp sensing component includes an L-shaped plate 20, which is fixedly installed on the outside of the rotating shaft 2. A laser emitter 21 is installed on the bottom surface of the L-shaped plate 20, and a laser receiver 22 is installed on the top surface of the second mounting plate 19. The laser receiver 22 and the second mounting plate 19 are circularly eccentrically set, and the yarn breakage signal is triggered by laser sensing.

[0026] Furthermore, the drive mechanism includes a fixed frame 16, which is fixedly installed on the outside of the corresponding support plate 1. A drive motor 15 is fixedly installed on the outside of the fixed frame 16. A drive gear 14 is installed on the outside of the output shaft of the drive motor 15. A driven gear 13 is installed on the outside of the rotating shaft 2, and the driven gear 13 meshes with the drive gear 14.

[0027] Furthermore, the drive motor 15 adopts a conical rotor motor with a power-off braking function, and the pitch circle diameter of the drive gear 14 is smaller than the pitch circle diameter of the driven gear 13.

[0028] This utility model provides a rotating stop device for glass fiber weaving, the specific working principle of which is as follows:

[0029] First, the device is fixed to the front of the warp knitting take-up roller of the glass fiber warp knitting machine by the support plate 1, ensuring that the comb teeth 11 correspond to the warp yarns being conveyed;

[0030] Start the drive motor 15 and the negative pressure fan 4. The output shaft of the drive motor 15 drives the drive gear 14 to rotate. By meshing with the driven gear 13, the rotating shaft 2 is driven to rotate stably around the bearing 8. The fixed seat 9 rotates synchronously with the rotating shaft 2. The comb teeth 11 comb the warp yarns to prevent multiple warp yarns from crossing and tangling.

[0031] At the same time, the negative pressure generated by the negative pressure fan 4 enters the cavity 7 of the rotating shaft 2 through the connecting pipe 5 and the rotary joint 6, and finally forms an annular negative pressure zone through the micropores 3, which adsorbs the surrounding broken yarn.

[0032] When the warp yarn breaks, the broken yarn approaches the rotating shaft 2 under negative pressure and is wrapped and captured by the rotating bristles 10. The wrapping force pulls the pull wire 12, causing the second mounting plate 19 to rotate around the second rotating shaft 23 and torsion spring 24. When the rotation of the second mounting plate 19 causes the laser receiver 22 to deviate from the laser emitter 21 on the bottom surface of the L-shaped plate 20, the laser receiver 22 receives the signal and transmits it to the control system. The control system immediately controls the drive motor 15 to cut off the power and brake, and at the same time shuts down the warp knitting take-up roller. After the broken yarn is processed, the torsion spring 24 resets and drives the second mounting plate 19 back to its original position, and the device can be restarted.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
