Example (b):

as shown in fig. 1-3, the present invention provides a bottle mouth assembling machine, which comprises a feeding assembly, a tightening assembly 4 and a discharging assembly. The material loading subassembly is provided with two sets ofly, is used for carrying well cover and upper cover respectively. The tightening assembly 4 is used for tightening the middle sleeve and the upper cover. The blanking assembly is used for taking the assembled middle sleeve and the upper cover out of the screwing assembly 4.

The tightening assembly 4 includes a tray 41, a rod 42 and a rotating rod 43. The tray 41 is shaped like a disk. The tray 41 is provided with a hole 411 for placing a middle cover and an upper cover along the circumference. The feeding component and the discharging component are both circular disks matched with the object placing disk 41. The outer edges of the feeding assembly and the discharging assembly are provided with semicircular notches. The semicircular gap can just accommodate a middle sleeve or an upper cover. The tray 41 rotates relative to the feeding and discharging assemblies, and the feeding and discharging assemblies also rotate. In the rotating process, a middle sleeve or an upper cover is clamped in the round notch of the feeding assembly. The feeding assembly drives the middle sleeve or the upper cover to rotate to the object placing plate 41. At this time, the circular notch of the feeding assembly just rotates to align with the storage hole 411 of the storage tray 41, so that the middle sleeve or the upper cover just falls into the storage hole 411. Then, the middle cover or the upper cover can rotate along with the object placing plate 41. The two feeding assemblies respectively convey the middle sleeve and the upper cover. The feeding assembly for conveying the middle sleeve is positioned in front of the feeding assembly for conveying the upper cover. In the same way, after the middle sleeve and the upper cover are screwed down, the middle sleeve and the upper cover rotate to the semicircular gap of the blanking assembly along with the material placing hole 411, and then the middle sleeve and the upper cover are transferred to the blanking assembly and gradually separated from the material placing disc 41 along with the blanking assembly.

The tightening assembly 4 further comprises a first guide block 44 and a second guide block 45 which are cylindrical. The outer wall of the first guide block 44 and the outer wall of the second guide block 45 are each provided with a guide groove 441 along the circumferential direction thereof. The guide groove 441 is waved up and down. The top bar 42 is disposed below the storage hole 411, and a sliding block 421 is disposed on one side of the top bar close to the first guide block 44 and matched with the first guide block 44. When the slider 421 rotates around the first guide block 44, the slider 421 slides along the guide groove 441 of the first guide block 44 to move up and down, so that the lift pin 42 moves up and down relative to the storage tray 41. The rotating rod 43 is disposed above the storage hole 411, and a sliding block 421 is disposed on a side of the rotating rod close to the second guiding block 45 and matched with the second guiding block 45. During the rotation of the slider 421 around the second guide block 45, the slider 421 slides along the guide groove 441 of the second guide block 45 to move up and down, so that the rotating rod 43 moves up and down relative to the storage tray 41.

The tightening assembly 4 also includes a gear plate 46. The rotating rod 43 is provided with driving teeth engaged with the gear plate 46. When the rotating lever 43 rotates around the gear plate 46, the rotating lever 43 rotates in cooperation with the gear plate 46.

A drum 431 is rotatably fitted around the outside of the rotating rod 43. A clamping groove is formed in the rotary drum 431, and a convex ring is arranged on the rotary rod 43 in a matching mode with the clamping groove. The collars are received in the pockets so that rotating rod 43 can only rotate within bowl 431 and cannot slide up and down within bowl 431.

In this specification, the mutual moving relationship among the one set of the rotating lever 43, the placing plate, and the lift lever 42 is described, and the mutual moving relationship among the other rotating lever 43, the placing plate, and the lift lever 42 is the same as the moving relationship of the present set. The guide groove 441 of the first guide block 44 and the guide groove 441 of the second guide block 45 are arranged in a matching manner, so that when the storage hole 411 is aligned with the notch of the middle sleeve charging tray 1, the ejector rod 42 descends to the lowest position and is positioned outside the storage hole 411; at the same time, the rotating rod 43 rises to the highest position and is positioned above the storage hole 411. At this time, the middle sleeve can smoothly enter the article placing hole 411. Continuing to rotate, the ejector rod 42 rises and gradually inserts into the interior of the middle sleeve. In the process, the rotating rod 43 gradually descends to press the middle sleeve, so that the middle sleeve is prevented from being jacked up and cannot be inserted into the middle sleeve when the ejector rod 42 ascends upwards. Subsequently, the jack 42 keeps rotating at the current height and the rotating rod 43 gradually rises. When the object placing hole 411 rotates to align with the notch of the upper cover material tray 2, the rotating rod 43 rises to the highest position again, and the upper cover can move to the upper part of the middle sleeve and cover the upper part of the middle sleeve. Subsequently, the rotating rod 43 is lowered again to press the upper cover against the top end of the middle sleeve. As the pressure of the rotating lever 43 increases, the frictional force between the rotating lever 43 and the upper cover drives the upper cover to rotate. At this time, the middle sleeve is restricted by the push rod 42 and cannot rotate, and the upper cover rotates relative to the middle sleeve and is screwed on the top end of the middle sleeve. When the combined middle sleeve and upper cover reach the lower tray 3, the ejector pin 42 has descended to the lowest position and the rotating rod 43 has ascended to the highest position. At this time, the combined middle sleeve and upper cover can enter the gap of the lower tray 3 and be taken away. The rotating rod 43, the object placing plate and the push rod 42 can repeat the above actions again after continuing to rotate, and then the combination of the middle sleeve and the upper cover is continuously carried out.

When the bottle mouth assembling machine is used, the middle sleeve and the upper cover of the two groups of feeding assemblies are respectively placed on the screwing assembly 4. After the upper cover and the middle sleeve are screwed down by the screwing component 4, the screwed middle sleeve and the screwed upper cover are taken away by the blanking component. The bottle mouth assembling machine can assemble the upper cover and the middle sleeve, and improves the production efficiency.

In order to ensure that the middle sleeve and the upper cover can be screwed down, the lower end of the rotating rod 43 is provided with a friction block. The friction block can be made of soft rubber with better anti-skid performance. Can ensure the perfect screwing of the upper cover and the middle sleeve. Meanwhile, the upper cover cannot be abraded by the relative rotation of the friction block and the upper cover after the upper cover is screwed down.

In this embodiment, a sliding rod 47 is slidably disposed inside the rotating rod 43. The lower extreme of rotary rod 43 is the bowl form of back-off, can wrap up the upper cover after its descends completely, effectively avoids the upper cover to pop out after the pressure. The sliding rod 47 can extend downwards into the bowl-shaped inner part at the bottom of the rotating rod 43, so that the upper cover is ejected out of the bowl-shaped inner part of the rotating rod 43, and accurate blanking is guaranteed. The top of the sliding rod 47 is provided with a guide disc 48. The guide disc 48 is provided with a wave-shaped guide track. After the middle sleeve and the upper cover are combined, the sliding rod 47 can be pushed by the guide track to extend into the bowl-shaped inner part at the bottom of the rotating rod 43 by continuously sliding along the guide disc 48, and then the upper cover is ejected. The slide lever 47 is provided with a spring 471 which drives it against the guide disk 48. The spring 471 has the function of ensuring that the sliding rod 47 is pressed against the guide disk 48.

In this embodiment, the roller 472 is disposed on the top of the sliding rod 47. The friction between the slide bar 47 and the guide rail is reduced, reducing wear.

In this embodiment, the storage tray 41 is provided with a plurality of storage holes 411 along the circumferential direction thereof. Each storage hole 411 is provided with a set of rotating rod 43 and a set of top rod 42 in a matching manner. The plurality of sets of the rotating rods 43 and the carrier rods 42 allow production efficiency to be improved.

In this embodiment, the upper end of the top rod 42 is provided with anti-slip lines. The antiskid lines can effectively prevent the middle sleeve from rotating and being not screwed well when the upper cover and the middle sleeve are screwed.

In this embodiment, the storage hole 411 is stepped. The inner diameter of the upper end of the storage hole 411 is larger than that of the lower end. This enables the middle sleeve to be accurately placed in the object placing hole 411. Meanwhile, when the push rod 42 descends to separate from the middle sleeve, the middle sleeve cannot be pulled into the object placing hole 411.

In this embodiment, a guide tube 432 is further sleeved outside the rotating rod 43. The rotating rod 43 can rotate and slide relative to the guide tube 432. The guide tube 432 limits the moving direction of the rotating rod 43 to prevent the rotating rod 43 from moving randomly.

The bottle mouth assembling machine further comprises a bottom plate 5, a driving motor 6, a first rotating disk 7, a second rotating disk 8 and a plurality of connecting rods 9. The driving motor 6 is connected to the base plate 5 and can drive the base plate 5 to rotate. Put thing board,
