Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a decorative thread conveying mechanism for automobile seat covers with a thread breakage alarm structure. Background Art

[0002] Car seats are an indispensable and important part of car accessories. They are used by drivers to drive cars and are also used by other passengers to sit. Currently, car seats are made of many types of materials, such as knitted, leather, suede, etc. In order to increase the aesthetics of car seats, decorative threads are generally used to decorate the seats. Therefore, during the production process of seats, the decorative threads generally need to be transported to the processing equipment to continuously provide the processing equipment with decorative threads until the decorative processing of the seats is completed.

[0003] The current decorative wire conveying structure generally includes two parts: wire pay-off and conveying. The wire pay-off structure is used to actively release the decorative wire, and the conveying structure is used to convey the decorative wire to the processing equipment. However, the existing conveying structure does not have any wire break alarm structure. Once the decorative wire in the wire pay-off or conveying structure is broken, no alarm can be provided to the staff, which will cause the conveying structure and the processing equipment to idle at the same time, easily causing equipment damage, and also reducing production efficiency. There is room for improvement. Utility Model Content

[0022] The pay-off assembly includes a circular disk 8, a sleeve rod 9 is fixedly connected to the front of the circular disk 8, a limit plate 10 is fixedly connected to the surface of the sleeve rod 9, a threaded rod 11 is fixedly connected to the front end of the sleeve rod 9, a pay-off roller 12 is inserted on the surface of the sleeve rod 9, a circular hole is opened at the front end of the pay-off roller 12 to match the sleeve rod 9, a limit groove is opened on the inner wall of the circular hole to match the limit plate 10, and an internal threaded collar 13 is threadedly connected to the surface of the threaded rod 11;

[0023] The pay-off roller 12 is inserted into the surface of the sleeve rod 9, and the second motor 6 drives the sleeve rod 9 to rotate through the round shaft 7 and the circular disk 8, thereby driving the pay-off roller 12 to rotate through the limit plate 10, and the internal threaded collar 13 can be screwed into the surface of the threaded rod 11 to lock the pay-off roller 12, ensuring that the pay-off roller 12 will not be separated during the rotation process;

[0024] The alarm assembly includes a positioning rod 14, a spring 15 is sleeved on the surface of the positioning rod 14, a movable block 16 is slidably connected to the inner rear wall of the chute, a through hole is opened on the side of the movable block 16, and the movable block 16 is slidably connected to the surface of the positioning rod 14 through the through hole, one end of the spring 15 overlaps the right side of the movable block 16, and the other end overlaps the right inner wall of the chute, and a tension roller 17 is fixedly connected to the front of the movable block 16;

[0025] A control switch 18 is fixedly connected to the left inner wall of the chute, a fixed groove is opened on the left inner wall of the chute, an electric push rod 19 is fixedly connected to the inner wall of the fixed groove, and the position of the electric push rod 19 corresponds to the position of the movable block 16. An audible and visual alarm 20 is fixedly connected to the upper surface of the positioning platform 1, and the control switch 18 is electrically connected to the audible and visual alarm 20;

[0026] The decorative line on the pay-off roller 12 passes around the tension roller 17 and is wound around the conveying roller 5, and the conveying roller 5 is used to convey the decorative line. During the conveying process of the decorative line, the tension roller 17 is tightened by the conveying roller 5, which will drive the movable block 16 to move to the right on the surface of the positioning rod 14 and squeeze the spring 15 to cause it to deform. Once the decorative line is disconnected, the tension roller 17 will immediately lose its restriction. At this time, the movable block 16 is subjected to the reaction force generated by the spring 15, moves quickly to the left and squeezes the control switch 18. The control switch 18 automatically turns on the sound and light alarm 20, reminding the staff to rewind and reconnect the decorative line in time.

[0027] Working principle: First, insert the pay-off roller 12 into the surface of the sleeve rod 9. The limit plate 10 on the surface of the sleeve rod 9 can be stuck in the limit groove to lock the pay-off roller 12. At this time, screw the internal threaded ring 13 into the surface of the threaded rod 11, and pass the decorative line on the surface of the pay-off roller 12 around the tension roller 17, and then connect it to the conveying roller 5. Use the conveying roller 5 to convey the decorative line. During the operation, the tension roller 17 is tightened by the conveying roller 5. The tension roller 17 can drive the movable block 16 to move to the right on the surface of the positioning rod 14 and squeeze the spring 15, causing the spring 15 to deform. At this time, the movable block 16 is away from the control switch 18. Once the decorative line is disconnected, the tension roller 17 loses its restriction. At this time, the spring 15 generates a reaction force, which can drive the movable block 16 to move to the left on the surface of the positioning rod 14 until the movable block 16 touches the control switch 18. The sound and light alarm 20 is turned on by the control switch 18, and the sound and light alarm 20 is used to remind the staff that the decorative line is disconnected and to reconnect the operation. At the same time, the electric push rod 19 can drive the movable block 16 away from the control switch 18 after the movable block 16 contacts the control switch 18 for a period of time, so as to avoid noise pollution caused by turning on the sound and light alarm 20 for a long time, and the detection effect of the broken line is more accurate and more flexible.
