Description

Technical Field

[0001] This invention relates to the field of wire winding equipment technology, specifically to a multi-station automatic and efficient winding equipment for household appliance power cords. Background Technology

[0002] Household appliances (such as vacuum cleaners, rice cookers, microwave ovens, etc.) are usually equipped with power cords for connecting to the power source. These power cords typically have a power plug for connecting to the power grid and an electrical plug for connecting to the appliance itself at both ends. In production, packaging, or daily life, in order to prevent the power cords from getting tangled, knotted, or taking up too much space, it is necessary to wind the power cords into neatly bundled coils. Currently, some semi-automatic or fully automatic winding equipment specifically designed for winding power cords with plugs on both sides has been developed.

[0003] Currently, most existing power cord winding equipment uses a clamping and rotating method to wind power cords. For example, the utility model patent with authorization announcement number CN216736923U discloses a plug power cord winding device, and the invention patent with publication number CN114229614A discloses a dual-station winding machine. The automation level of the equipment in the above solutions is low, many operation links still rely on manual intervention, and there are few workstations, making it impossible for multiple workstations to work together. This results in long waiting times during power cord loading, winding, and unloading, reducing overall production efficiency. Summary of the Invention

[0027] The screwing component includes two retaining rings 31, two clamping blocks 32, two toothed plates 33, a third motor 34, a third gear 35, and two first telescopic cylinders 36. The two first telescopic cylinders 36 are horizontally fixedly sleeved inside the horizontal section of the stop frame 19.

The center of the arc coincides with the axis of the rotating frame 2. The multiple scrapers 47 are vertically fixed on the bottom side of the rotating frame 2 and are evenly distributed in a circle. The multiple scrapers 47 are all located inside the trough 42. The second conveyor belt device 43 is horizontally embedded on the upper side of the base 1, and the input end is located on the bottom side of the output end of the trough 42.

[0029] When using this device to wind power cords, the entire device operates, and the first conveyor belt device 5 drives multiple card holders 9 to rotate, thereby pushing multiple power cords in the card holders 9. When loading power cords, the plug end of the power cord is pushed into the card holder 9, and the two card blocks 10 deflect inwards towards the inside of the card holder 9. After the power cord enters the inside of the card holder 9, the two card blocks 10 reset under the action of the torsion spring, locking the power cord in the card holder 9. The power cord plug is supported by the card holder 9, and the power cord moves vertically downwards under its own weight, moving with the first conveyor belt device 5.

[0030] Once the winding mechanism is aligned with the carriage 12, the first conveyor belt device 5 and the first motor 6 stop rotating, and the first motor 13 starts. The first motor 13 drives the rack 15 to move through the second gear 14. The rack 15 drives the carriage 12 to move, pushing the plug at the top of the power cord. As the carriage 12 pushes, the plug pushes the two locking blocks 10 outward. The two locking blocks 10 deflect, and their ends, which are close to each other, contact the ends of the two adjacent spools 18 located at the bottom of the turntable 16. Under the pushing action of the carriage 12, the plug at the top of the power cord disengages from the locking bracket 9 and slides between the two spools 18 at the bottom. The two locking blocks 10 reset under the action of the torsion spring, blocking the locking bracket 9. Finally, the plug at the top of the power cord is pushed to the end of the two spools 18 near the turntable 16, and the plug at the bottom of the power cord is inserted into the insert 45. The power cord to be wound is unloaded from the conveying mechanism and pushed and loaded onto the winding mechanism.

[0031] Once the power cable loading is complete, the first motor 13 reverses its rotation, causing the carriage 12 to reset. Then, the first motor 6 starts, and through the meshing of the first gear 7 and the gear ring 8, it drives the rotating frame 2 to deflect, so that the next set of unloaded winding mechanisms aligns with the output end of the first conveyor belt device 5 to load the next movie power cable.

[0032] With the cooperation of the conveying mechanism and the rotary mechanism, the power lines that need to be wound can be loaded onto the winding mechanism in sequence. Multiple winding mechanisms form a multi-station layout, which can realize the synchronous winding of multiple power lines at multiple stations, thereby improving efficiency.

[0033] After the completed winding mechanism leaves the output area of ​​the first conveyor belt device 5, the second motor 17 starts, driving the turntable 16 to rotate. The turntable 16 drives multiple rollers 18 to rotate, thereby winding the power cord. During the winding process, the upper end of the power cord is coiled around the outside of the multiple rollers 18, and the lower end pulls the pull block 44 to move upward. Under the gravity of the pull block 44, the power cord is taut and tensioned, ensuring that the power cord is smoothly wound into a coil.

[0034] After the winding is completed, the second motor 17 stops rotating. At this time, the first guide groove 191 and the second guide groove 181 are aligned. The second motor 30 starts and drives multiple hollow worm gears 28 to rotate through the transmission shaft 29, thereby driving multiple worm wheels 27 to rotate synchronously. The multiple worm wheels 27 drive the corresponding pressure rollers 26 to rotate. The pressure roller 26 on one side rotates and pushes the cable tie 25 between the two pressure rollers 26. At the same time, multiple pairs of pressure rollers 26 perform rolling and straightening operations on the cable tie 25.

[0035] As the cable tie 25 is conveyed, its end passes through the first guide groove 191, then turns into the second guide groove 181, then turns into the third guide groove 161, and finally enters the conduit 20. Under the sealing of multiple pairs of seals 21, the end of the cable tie 25 will not pass through the first guide groove 191, the second guide groove 181, the third guide groove 161 and the groove on the side of the conduit 20 due to the pushing force. It will sequentially pass through the first guide groove 191, the second guide groove 181, the third guide groove 161 and the conduit 20, and finally return to the first guide groove 191, and be wound into a circle on the coiled power cord.

[0036] After the cable tie 25 forms a loop and its end returns to the first guide groove 191 and is positioned between the two clamping blocks 32, the two first telescopic cylinders 36 extend, driving the retaining rings 31 to move, so that the two clamping blocks 32 fit together. The two anti-slip layers 37 elastically deform, clamping the end of the cable tie 25 and itself. The clamping blocks 32 are semi-cylindrical, and the two clamping blocks 32 fit tightly together to form a complete cylinder. At the same time, the two toothed plates 33 fit tightly together to form a complete gear. The two retaining rings 31 form a complete sleeve structure, sealing the two clamping blocks 32. Then the third motor 34 starts, and through the third gear 35, it drives the two toothed plates 33 that form the complete gear to rotate, thereby realizing the rotation of the two clamping blocks 32 and twisting the cable tie 25.

[0037] Under the twisting action of the two clamping blocks 32, the cable tie 25 located on the outside of the power reel is twisted into a spiral shape. At the same time, under the tightening and shrinking action, the cable tie 25 is separated from the first guide groove 191, the second guide groove 181, the third guide groove 161 and the conduit 20 between multiple pairs of seals 21.

[0038] Three sets of binding components bind the coiled power cord at three points. After binding, the two third telescopic cylinders 40 extend, driving the linkage 41 to move. The linkage 41 drives the three baffles 19 to slide outward. Under the clamping action of the three pairs of clamping blocks 32, the three sets of twisted cable ties 25 move the power cord with the baffles 19, disengaging from the spool 18 and the insert 45. After the coiled power cord is completely disengaged from the spool 18, the second telescopic cylinder 38 extends, driving the cutter 39 to move. Under the squeezing action of the cutter 39 and the inner wall of the first guide groove 191, the cable ties 25 are cut off. The second telescopic cylinder 38 shortens and resets. Then, the two first telescopic cylinders 36 shorten, causing the two clamping blocks 32 to separate, releasing the clamping force on the twisted cable ties 25. Under the gravity of the power cord coil, the power cord coil with the three sets of twisted cable ties 25 falls into the material trough 42, completing the unloading operation of the coiled power cord.

[0039] During unloading, the plug on the bottom side detaches from the socket 45, and the pull block 44 falls back onto the two stop bars 46 under its own weight. Then, the third telescopic cylinder 40 shortens, causing the three sets of bundling components to reset, preparing for the winding and bundling of the next power cord.

[0040] Adjust the positions of the two levers 46 according to the length of the power cord to meet the tension requirements of power cords of different lengths.

[0041] The three vertical sections of the baffle 19 and the turntable 16 form a two-sided limiting structure to limit the wound power cord and prevent it from coming off the multiple spools 18.

[0042] During the rotation of the rotating frame 2, the loaded power cord is wound up. After winding, the three sets of binding components tighten the three cable ties 25 on the coiled power cord, achieving a secure fit. With the cooperation of the pushing mechanism, the unloading is completed, thus achieving the unloading operation of the wound power cord coil.

[0043] With the cooperation of three sets of strapping components and the pushing mechanism, the winding, strapping and unloading of the power cord can be completed sequentially within one rotation cycle during the rotation of the rotating frame 2, further improving efficiency and finally obtaining a coil of power cord with three sets of tightened straps 25, which is convenient for subsequent packaging operations.

[0044] After the wound and bundled power cord roll falls into the material trough 42, the rotation of the rotating frame 2 causes multiple scrapers 47 on its bottom side to rotate in the material trough 42, pushing the power cord roll in the material trough 42. Finally, the power cord roll is pushed onto the second conveyor belt device 43 for output, which facilitates subsequent packaging operations.
