[0029] like Fig.10 and Fig.11The bottle cap feeding device 7 includes a frame 78, a transmission module 76 is provided on the front of the upper end surface of the frame 78, and a feeding turntable 74 is provided at the output end of the transmission module 76, a second transfer module 75 is provided near the middle of the upper end surface of the frame 78, the upper end surface of the frame 78 is threadedly connected to a limiting bottom plate 77 through the second transfer module 75, the inner end surface of the limiting bottom plate 77 is provided with a first transfer module 73, and two groups of bottle cap flow channels 71 are threadedly connected to the inner end surface of the first transfer module 73, a bottle cap conveying device 72 is provided on the top of the limiting bottom plate 77, blocking cylinders 79 are provided at the outlets of the two groups of bottle cap flow channels 71, and a blocking plate 710 is provided at the top of the blocking cylinder 79.

[0030] like Fig.12 The bottle cap handling device 72 includes a limiting card plate 721, a double-axis cylinder 722 is provided on the inner end surface of the limiting card plate 721, a connecting seat 727 is fixedly provided on the lower end surface of the double-axis cylinder 722, a push plate 723 is provided on the output end of the double-axis cylinder 722, two groups of clamping cylinders 724 are provided at the front part of the push plate 723, clamping arms 725 are provided on both side ends of the clamping cylinder 724, and bottle cap clamps 726 are provided at the inner end ends of the two groups of clamping arms 725.

[0031] like Figure 5 and Fig.12 The bottle body clamp 327 and the bottle cap clamp 726 are both provided with V-shaped clamping grooves, and the bottle cap clamp 726 is fixedly connected to the bottle cap 8 through the V-shaped clamping groove, and the bottle body clamp 327 is fixedly connected to the bottle body 9 through the V-shaped clamping groove. The V-shaped setting in the V-shaped clamping groove can facilitate the subsequent adaptability of the bottle body clamp 327 and the bottle cap clamp 726 to clamp products of different diameters.

[0032] like Fig.10 The feeding openings of the two groups of bottle cap flow channels 71 are directly opposite to the two discharge ports of the loading turntable 74, and the two bottle cap flow channels 71 are threadedly slidably connected to the upper end surface of the frame 78 through the second transfer module 75. The staff can adjust the conveying spacing of the bottle cap flow channels 71 and the loading spacing between the bottle cap flow channels 71 and the loading turntable 74 through the first transfer module 73 and the second transfer module 75, so as to facilitate the subsequent loading of bottle caps 8 of different models.

[0033] like Figure 7 The connecting rotating head 34 is directly opposite to the two groups of bottle body clamps 327, and the positioning sensor 427 is electrically connected to the servo motor 425. The positioning sensor 427 can detect the position of the bottle body 9, thereby improving the accuracy of the subsequent synchronous belt guide module 424 in separating the bottle body 9.

[0034] like Figure 8The horizontal linear module 36 and the vertical linear module 37 are both electrically connected to the bottle body sensing module 46. The inner walls of the two sets of synchronous belt guide modules 424 are fitted and connected to the bottle body 9. The two sets of synchronous belt guide modules 424 can fit the inner wall of the bottle body 9, which is convenient for the subsequent synchronous belt guide module 424 to stop and limit the bottle body 9, thereby improving the stability of the subsequent bottle separation of the bottle body 9.

[0035] Working principle: when the bottle cap 8 is screwed on the upper part of the bottle body 9, the capping operation is performed first. When the bottle cap 8 is loaded, the bottle cap 8 is first placed on the loading turntable 74. The loading turntable 74 can be rotated under the drive of the transmission module 76, so that multiple groups of bottle caps 8 are output in sequence, and then the bottle caps 8 are transported to the inside of the bottle cap flow channel 71 in sequence until they are pressed to the blocking plate 710. When the bottle caps 8 are transported to the blocking plate 710, the blocking cylinder 79 can drive the blocking plate 710 to descend. At the same time, the two groups of clamping cylinders 724 can drive the bottle cap clamps 726 to clamp and limit the bottle caps 8 inside the bottle cap flow channel 71 through the clamping arms 725, and then wait for the subsequent signal for loading the bottle caps 8. Then, the bottle separation and loading operation is performed. When the bottle bodies 9 are separated and loaded, the staff can randomly place the bottle bodies 9 on the first conveying module 43. The first conveying module 43 can stably convey the bottle bodies 9. When the bottle bodies 9 enter the bottle separation range of the guide device 42, the servo motor 425 can drive the synchronous belt guide module 424 at the bottom to rotate. When the bottle bodies 9 pass the positioning sensor 427, the synchronous belt guide module 424 stops for 0.5 seconds. At the same time, the front bottle bodies 9 continue to move under the drive of the second conveying module 48, thereby achieving the bottle separation effect. Finally, the capping operation is performed. The bottle body 9 after the bottle separation is conveyed by the second conveying module 48. The bottle body sensing module 46 can sense the bottle body 9 in real time, record the current position of the bottle body 9, and calculate the capping position. At this time, the double-axis cylinder 722 obtains the feeding signal, and the double-axis cylinder 722 can drive the push plate 723 to move forward, so that the push plate 723 can drive the two groups of bottle caps 8 clamped by the bottle cap clamp 726 to be positioned at the bottom of the fixed jaws 33. The fixed jaws 33 are opened under the drive of the connecting rotating head 34, and then the fixed jaws 33 are moved downward under the drive of the vertical linear module 37 to limit the bottle cap 8. After the limiting is completed, the wide cylinder 321 The swing arm 328 and the bottle body clamp 327 can be synchronously driven to move centripetally through the alignment holder 329, so that the two groups of bottle body clamps 327 can complete the fixed limit of the bottle body 9, and at the same time, the horizontal linear module 36 can synchronously drive the vertical linear module 37 to move sideways following the speed of the second conveying module 48, so that in the process of lateral movement, the vertical linear module 37 drives the power module 35 and the fixed clamp 33 to move downward synchronously, and at the same time, the power module 35 drives the connecting rotor 34 to rotate at high speed, thereby tightening the bottle cap 8 on the upper part of the bottle body 9, and then the second conveying module 48 continues to convey. At this time, the bottle cap sensing module 47 can detect the bottle cap 8 after screwing to prevent the phenomenon of missing screwing.
