[0027] Please refer to Figures 1-9 The utility model provides an embodiment: a cap falling mechanism, including rack 1, and one side of rack 1 is also equipped with cap falling assembly 3;Cap falling assembly 3 includes support frame 30, and the cap stacking assembly 32 of mounting on support frame 30;Cap stacking assembly 32 includes support plate 312, and support plate 312 is equipped with limiting rod 313;Among them, the number of limiting rod 313 is multiple, and is surrounded on support plate 312 through multiple limiting rod 313, to form stacking area 320 for stacking bottle cap on cap stacking assembly 32;Support plate 312 is also equipped with grabbing piece 315, and bottle cap in stacking area 320 is transferred to support frame 30 through grabbing piece 315, to realize the automatic conveying of bottle cap.

[0028] In summary, the use of the grabbing piece 315 moves the bottle cap in the stacking area 320 to the support frame 30, which can realize the continuous conveying of the bottle cap, and can avoid the problem of affecting production caused by the free falling of the bottle cap.

[0029] In addition, the stacking area 320 is surrounded by a plurality of limiting rods 313, for example, four limiting rods 313 are arranged in a circular ring on the support plate 312, so that the structure of the stacking area 320 is simple and light in weight, and the stacking capacity of the stacking area 320 can be adjusted by increasing or decreasing the length of the limiting rod 313. The grabbing piece 315 is a VAC series vacuum cylinder.

[0030] In order to ensure that the falling bottle cap can move smoothly to the bottle opening, the support frame 30 is provided with a first flow channel 33 and a second flow channel 34; wherein the grabbing piece 315 transfers the grabbed bottle cap to the first flow channel 33 and the second flow channel 34, and moves the bottle cap to the bottle opening through the first flow channel 33 and the second flow channel 34.

[0031] Further, the side of the support frame 30 is also provided with a driving rod 37, and the first flow channel 33 and the second flow channel 34 are moved towards or away from each other by rotating the driving rod 37, so that the first flow channel 33 and the second flow channel 34 guide bottle caps of different diameters.

[0032] In summary, two flow channels are used to guide the movement of the bottle cap, and the distance between the two flow channels is adjusted by rotating the driving rod 37, so that the two flow channels can accommodate bottle caps of different diameters. Based on this, while ensuring that the bottle cap moves smoothly to the bottle opening, the device can also adjust the distance between the two flow channels so that the device can adapt to bottle caps of different diameters. The driving rod 37 is preferably a screw rod.

[0033] In order to avoid the bottle cap jumping out of the two flow channels during movement, causing the bottle cap to fall elsewhere and affecting production efficiency, the support frame 30 is also provided with a pressing plate 35, and the pressing plate 35 guides the bottle cap to move smoothly above the first flow channel 33 and the second flow channel 34. Therefore, when the bottle cap slides between the two flow channels, the pressing plate 35 can be above the two flow channels, guiding the bottle cap to move along the predetermined track, so that the problem of off-track movement of the bottle cap can be avoided.

[0034] At the same time, the outer sides of the first flow channel 33 and the second flow channel 34 are provided with a first chuck 38, and the first chuck 38 prevents the bottle cap from sliding out of the first flow channel 33, so that the first chuck 38 can block the bottle cap from continuing to slide, and the bottle cap can be stopped between the two flow channels, which can effectively prevent the bottle cap from flying out of the flow channel due to inertia.

[0035] Wherein, the outer side of the first flow channel 33 and the second flow channel 34 is provided with the first guide rod 310, and the first spring 39 is sleeved outside the first guide rod 310, and the first nut 311 is rotated on the first guide rod 310 to compress or release the first spring 39, so that the first chuck 38 between the two flow channels can clamp the bottle cap with different diameters. At the same time, when the bottle cap falls into the bottle mouth, the two first chucks 38 can also be automatically released with the movement of the bottle, so as to facilitate the movement of the bottle cap with the bottle. In addition, the supporting plate 312 is also provided with a mounting frame 314, and the grabbing piece 315 is fixed below the first flow channel 33 and the second flow channel 34 through the mounting frame 314. When grabbing is needed, the suction cup end of the grabbing piece 315 enters the stacking area 320 through the first flow channel 33 and the second flow channel 34 to grab the bottle cap. When the bottle cap is grabbed, the suction cup end of the grabbing piece 315 is reset, and the two flow channels are blocked, so that the bottle cap can be smoothly transferred from the stacking area 320 to the two flow channels.

[0036] In order to ensure that the bottle cap can be horizontally dropped into the bottle mouth, the end of the pressing plate 35 facing the first chuck 38 is also provided with a pressing cover plate 322, and the pressing cover plate 322 promotes the bottle cap to be horizontally dropped into the bottle mouth. When the bottle cap slides down from the flow channel, the pressing cover plate 322 presses the bottle cap on the bottle mouth from above, so that the bottle cap can be connected with the bottle mouth horizontally. Wherein, the support frame 30 is also provided with a support 36, and the support 36 is also provided with a top rod 323, one end of the top rod 323 passes through the support 36 and is connected with the pressing plate 35, and the other end of the top rod 323 passes through the support 36 and is threadedly connected with the third nut 324, so that the gap between the pressing plate 35 and the facing surface of the two flow channels can be adjusted by rotating the third nut 324. In addition, the pressing plate 35 also has the first guide rod 310, the first nut 311 mounted on the first guide rod 310 and the first spring 39 sleeved outside the first guide rod 310, so as to further ensure that the bottle cap can be smoothly and horizontally dropped into the bottle mouth.

[0037] On the basis of the above scheme, the support frame 30 is also provided with an adjusting plate 31, and the middle part of the adjusting plate 31 is connected with the lead screw 5, and the lead screw 5 promotes the whole falling cap assembly 3 to ascend and descend on the rack 1. Therefore, the whole falling cap assembly 3 can be adjusted in position on the rack 1. In addition, one end of the lead screw 5 passes through the rack 1 and is connected with the hand wheel 4, so that the user can rotate the lead screw 5 through the hand wheel 4.

[0038] In order to enable the stacking area 320 to also stack bottle caps of different diameters, the limiting rod 313 is further provided with a sliding part 316 which slides on the upper surface of the support plate 312, and the sliding part 316 is connected to the support plate 312 by means of a fastener such as a bolt which passes through a waist-shaped slot on the sliding part 316, so as to position the limiting rod 313 after adjusting the position.

[0039] In order to avoid the bottle cap from falling onto the flow channel without being grabbed by the grabbing part 315, the lower end of the limiting rod 313 is further provided with a second chuck 321, and the second chuck 321 blocks the bottle cap in the stacking area 320 when there is no external force, specifically, the side surface of the limiting rod 313 is provided with a second guide rod 317, and the second guide rod 317 is threadedly connected to a second nut 319 provided at one end of the second guide rod 317 after passing through a second spring 318 provided thereon, so that the second spring 318 can also be used to prevent the bottle cap from falling automatically.

[0040] In addition, the lower portion of the cap dropping assembly 3 is further provided with a conveying belt 2, and the bottle is moved to the cap outlet of the cap dropping assembly 3 by the conveying belt 2, so that the assembled bottle and bottle cap can be moved to the next station by the conveying belt 2.
