[0002] In the field of fiber production technology, taking the glass fiber industry as an example, the raw fiber cakes produced from glass fiber inorganic non-metallic materials are drawn, dried and then put into the winding process. After the winding process is completed, the wound yarn needs to be weighed and manually transported to the conveyor chain, and then flowed into the next production process. After the yarn is produced, the yarn needs to be unloaded and weighed by the unloading machine.

[0003] The current method for weighing yarn spools on unloading machines is to manually place the yarn spools onto a fixed scale. Since the yarn spools are quite heavy, this greatly increases the manual weighing workload, and the time intervals for manual weighing are not very accurate, which in turn reduces the accuracy of the yarn spool weighing. Utility Model Content

A circular limiting plate 24; a hydraulic rod 2 fixed to the top of the chassis 1 can drive the connecting column 5 and the weighing device 6 set above it to move upward to meet the yarn ball discharge ports of different heights of the unloading machine, so that each weighing device 6 can be aligned with the yarn ball on the unloading machine, and the yarn ball can be accurately dropped into the weighing device 6 through the limiting plate 24; the setting of the drive component realizes the effect of automatic continuous weighing of yarn balls on the unloading machine, which greatly improves the weighing efficiency of yarn balls on the unloading machine; an electric push rod 7 fixed between a pair of rotating blocks 21 and the setting of the weighing device 6 rotating at the end of the connecting column 5 through the connecting block 17 can automatically unload the yarn balls on the unloading machine.

[0024] Combination Figure 1 and Figure 3 The drive assembly includes a servo motor 8, with a fixed plate 9 fixedly attached to the bottom of the servo motor 8. A rotating shaft 10 fixedly attached to the top of the rotating drum 4 is fixedly attached to the output end of the servo motor 8. A rotatable ring block 11 is sleeved on the outer side of the hydraulic rod 2. A telescopic rod 12 is fixedly attached to the outer side of the ring block 11. The top of the telescopic rod 12 is slidably mounted on the bottom of the fixed plate 9. An annular groove 13 is provided at the bottom of the fixed plate 9. A first slider 14 is slidably connected inside the annular groove 13. The first slider 14 is fixedly attached to the top of the telescopic rod 12. Because the rotatable ring block 11 is sleeved on the outer side of the hydraulic rod 2, when the servo motor 8 fixedly attached to the top of the fixed plate 9 drives the rotating drum 4 to rotate through the rotating shaft 10, it can synchronously drive the connecting column 5 to rotate. This allows the telescopic rod 12 to rotate synchronously after being contacted by the rotating contact of the connecting column 5, and the first slider 14 fixedly attached to the top of the telescopic rod 12 will slide in the annular groove 13 provided at the bottom of the fixed plate 9.

[0025] Combination Figure 4The rolling assembly includes a roller 15 fixed to the inner wall of the rotating drum 4 and a ball 16 fixed to the top of the inner side of the rotating drum 4. The surface of the roller 15 rolls in contact with the outer side of the fixed block 3. The top of the fixed block 3 has a circular hole for the rotation of the ball 16. As the rotating drum 4 rotates, the roller 15 fixed to the inner wall of the rotating drum 4 and the ball 16 fixed to the top of the inner side of the rotating drum 4 rotate on the outer side of the fixed block 3 and inside the circular hole at the top of the fixed block 3, respectively. Therefore, the rolling assembly reduces friction by rolling, which can reduce the output torque of the servo motor 8.

[0026] Combination Figure 1 , Figure 3 and Figure 5 A connecting block 17 is fixedly connected to the outside of the weighing device 6. A rotating rod 18 is rotatably connected to the end of the connecting column 5. The connecting block 17 is rotatably connected to both ends of the rotating rod 18. A pair of short plates 19 are fixedly connected to the bottom of the weighing device 6 and the surface of the chassis 1. A connecting shaft 20 is fixedly connected between the pair of short plates 19. A rotating block 21 is rotatably connected to the outside of the connecting shaft 20. An electric push rod 7 is fixedly connected between the pair of rotating blocks 21. A sliding groove 22 is opened on the surface of the chassis 1. A second slider 23 is slidably connected inside the sliding groove 22. The second slider 23 is fixedly connected to the bottom of the pair of short plates 19. On the end; by rotating the connection fixed to the outside of the weighing device 6 to both ends of the rotating rod 18 at the end of the connecting column 5, and fixing the electric push rod 7 between the bottom end of the weighing device 6 and the rotating block 21 on the surface of the chassis 1, the yarn spool on the unloading machine can be automatically unloaded; the sliding groove 22 on the surface of the chassis 1, and the second slider 23 fixed to the rotating block 21 is slidably connected inside the sliding groove 22, so that multiple weighing devices 6 rotate synchronously, and the yarn spool can be weighed while the weighed yarn spool is rotated to the output device for the next step of processing.

[0027] The implementation principle of an automatic weighing device for a drum unloader in this embodiment is as follows:

[0028] Before weighing, the hydraulic rod 2 fixed to the top of the chassis 1 is turned on to move the weighing device 6 upward until it is directly below the yarn ball discharge port of the unloading machine. Then, the servo motor 8 fixed to the top of the fixed plate 9 is turned on to drive the rotating shaft 10 to rotate. Because the roller 15 on the inner wall of the rotating drum 4 and the ball 16 fixed to the top of the inside of the rotating drum 4 rotate on the outside of the fixed block 3 and inside the round hole opened at the top of the fixed block 3 respectively, the rotating drum 4 fixed to the rotating shaft 10 rotates while driving the connecting column 5 and the weighing device 6 to rotate in a circle around the rotating shaft 10 as the axis.

[0029] When the drum 4 rotates, because the hydraulic rod 2 is fitted with a rotatable ring block 11 on the outside, it can synchronously drive the connecting column 5 to rotate, so that the telescopic rod 12 rotates synchronously after being contacted by the rotating connecting column 5. The first slider 14 fixed to the top of the telescopic rod 12 will slide in the annular groove 13 opened at the bottom of the fixed plate 9. At the same time, the electric push rod 7 located between the bottom of the weighing device 6 and the surface of the chassis 1 can rotate synchronously, and the rotating block 21 fixed to the outside of the connecting shaft 20 between a pair of short plates 19 on the surface of the chassis 1 can synchronously drive the second slider 23 to rotate in the groove 22 opened on the surface of the chassis 1.

[0030] The synchronous rotation of multiple weighing devices 6 enables the equipment to weigh the yarn ball while simultaneously rotating the weighed yarn ball to the output device for further processing.

[0031] When the yarn ball is rotated above the output device, simply turn on the electric push rod 7 to retract it, so that the connecting block 17 fixed to the outside of the weighing device 6 rotates downward to the rotating rod 18 at the end of the connecting column 5.

[0032] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
