Description

Technical Field

[0001] The utility model relates to the technical field of cord take-up and pay-off lines, in particular to a take-up and pay-off line breakage detection device. Background Art

[0002] Cord, also known as cord for short, is the warp material used in woven tire cord fabrics. It's primarily used in the manufacture of rubber products like tires, conveyor belts, and transmission belts. There are several types of cord, including viscose, polyamide, polyester, and aromatic polyamide. Cord serves as the backbone material in rubber products, enhancing the product's strength and durability. For example, nylon cord is used in tire cord fabric, serving as the rubber's backbone. During tire manufacturing, cord is coated with glue and wrapped with fabric to create the tire's shape. It typically sits within the tire's inner layer, providing crucial support. During cord production, it's wound using pay-off and take-up equipment. External forces can cause the cord to break during the rewinding process.

[0003] In the prior art, a wire breakage detection device is provided to detect whether the cord is retracted or released during the retraction and release process. However, after the wire harness breaks, if the retraction and release mechanism continues to rewind because it does not receive the stop command in time, the retracted cord will become loose and fall off, thereby affecting the progress of the overall retraction and release work and causing waste of part of the cord.

Multiple groups of positioning cylinders 26 are arranged corresponding to the left end of the retracting roller 11. Two groups of symmetrically distributed screws 6 are provided in the fixing frame 3. The upper ends of the two groups of screws 6 are sleeved with synchronous wheels 7. A synchronous belt 8 is provided in the fixing frame 3. The synchronous belt 8 is respectively connected to the two groups of synchronous wheels 7 for transmission. The two groups of screws 6 pass through the fixing frame 3 and are rotatably connected to the fixing frame 3 through bearings. The two groups of screws The rod 6 passes through the corresponding adjustment frame 4 and is threadedly connected to the adjustment frame 4. A first gear 15 is sleeved on the mounting rod 13. A rack 19 is provided in the mounting seat 2. The rack 19 is slidably connected to the mounting seat 2. The rack 19 is meshed with the first gear 15. A solenoid 16 is provided in the mounting seat 2. The solenoid 16 is arranged corresponding to the rack 19. A solenoid 17 is sleeved on the solenoid 16. A power supply device 18 is provided in the mounting seat 2. The two ends of the solenoid are respectively connected to the positive and negative poles of the power supply device 18.

[0023] The fixed frame 3, the adjusting frame 4 and the roller 5, the infrared emitting device 9 and the corresponding infrared receiving device 10 are used to detect whether the cord is broken during the process of winding and unwinding. The spacing between the two sets of adjusting frames 4 and the roller 5 can be adjusted according to the actual model of the cord, which effectively expands the application range of the broken wire detection equipment. During the process of winding and unwinding, the infrared receiving device 10 will receive the infrared signal emitted by the infrared emitting device 9, and then transmit the detection information to the control unit. The unit promptly disconnects the power supply device 18 to energize the solenoid 17, and the magnetic field around the solenoid 16 disappears, and the metal rack 19 no longer has a fixing effect. Under the action of the torsion spring 14, the deflection frame 12 drives the sleeve 20 to deflect toward the retracting roller 11, so that the sleeve 20 fits with the retracting roller 11 and the curtain coil on the retracting roller 11, and has a certain pressure on the retracting roller 11 and the curtain coil on the retracting roller 11, so as to prevent the curtain coil wrapped on the retracting roller 11 from loosening and falling due to a sudden break in the wire while the retracting roller 11 is still rotating.

[0024] As shown in the figure and Figure 6 As shown, a mounting ring 22 is provided inside the fixing ring 21, and the mounting ring 22 is rotatably connected to the fixing ring 21 through a bearing. An inner tooth 23 is provided on the mounting ring 22, and an outer tooth 24 is provided on the mounting ring 22. The adjusting rods 25 are all rotatably connected to the fixing ring 21 through a rotating shaft.

After the wire break occurs, the corresponding reel 11 is actively braked to further prevent the curtain coils from being scattered due to the continuous transmission of the reel 11 for several turns under the action of inertia. After the infrared emitting device 9 and the infrared receiving device 10 detect the wire break, the signal is transmitted to the control unit. The control unit controls the motor in the fixing ring 21 on the corresponding mounting seat 2 to drive the driving wheel 28 to rotate. During the rotation of the driving wheel 28, the mounting ring 22 rotates in cooperation with the internal gear 23, and the second gear 27 is used to make multiple groups of adjusting rods 25 rotate synchronously, and drive multiple groups of positioning cylinders 26 to shrink synchronously until the positioning cylinder 26 is in contact with the outer wall of the left end of the reel 11 and gradually tightened, so as to actively brake the reel 11. The positioning cylinder 26 is made of rubber with large friction. After the reel 11 is braked, it cooperates with the deflection frame 12 and the sleeve 20 so that the curtain coils wound thereon will not be easily loosened.

[0026] The utility model provides a device for detecting breakage of a retractable and retractable wire. The specific working principle is as follows: by adjusting the distance between the two groups of adjustment frames 4, the cord is allowed to pass between the two groups of rollers 5. During the normal retractable and retractable process, the infrared emitting device 9 emits an infrared photoelectric signal, which is blocked by the cord and the two groups of adjustment frames 4, and the infrared receiving device 10 cannot receive the signal. When the wire is broken during the retractable and retractable process, the infrared receiving device 10 will receive the infrared signal emitted by the infrared emitting device 9. At this time, the detection information is transmitted to the control unit, and the power supply device 18 is disconnected in time by the control unit to energize the solenoid 17. The magnetic field around the solenoid 16 disappears, and it no longer has a fixing effect on the metal rack 19. Under the action of the torsion spring 14, the deflection frame 12 drives the sleeve 20 to deflect toward the retractable and retractable roller 11, so that the sleeve 20 fits with the retractable and retractable roller 11 and the curtain coil on the retractable and retractable roller 11, and has a certain pressure on the retractable and retractable roller 11 and the curtain coil on the retractable and retractable roller 11 to avoid sudden breakage. The line is still rotating while the retracting roller 11 causes the curtain coils wound on the retracting roller 11 to loosen and fall off. After the infrared emitting device 9 and the infrared receiving device 10 detect the breakage, the signal is transmitted to the control unit. The control unit controls the motor in the fixed ring 21 on the corresponding mounting seat 2 to drive the driving wheel 28 to rotate. During the rotation of the driving wheel 28, the internal teeth 23 are used to rotate the mounting ring 22, and the second gear 27 is used to make multiple groups of adjusting rods 25 rotate synchronously, and drive multiple groups of positioning cylinders 26 to shrink synchronously until the positioning cylinders 26 are in contact with the outer wall of the left end of the retracting roller 11 and gradually tighten. The retracting roller 11 is actively braked. The positioning cylinder 26 is made of rubber and has a large friction force. After the retracting roller 11 is braked, it cooperates with the deflection frame 12 and the sleeve 20 so that the curtain coils wound thereon will not loosen easily. The model of the infrared emitting device 9 is SLLT660 universal 940nm transmitting tube, and the model of the infrared receiving device 10 is infrared transmitting and receiving tube IR / PT / PD.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
