[0004] The present application is achieved by the following technical solution: a rotary special-shaped bottle plug pressing machine, comprising a cam disc, a transmission shaft, a plug pressing head, an in-take screw rod, an in-take star wheel, a main star wheel, an out-take star wheel, and a plug feeding module. The in-take star wheel, the main star wheel, and the out-take star wheel are rotatably arranged. The in-take screw rod is connected to the in-take star wheel. A bottle guide plate is arranged between the in-take star wheel and the out-take star wheel. The in-take star wheel and the bottle guide plate form an in-take channel. The in-take channel is connected to the main star wheel. The out-take star wheel and the bottle guide plate form an out-take channel. The out-take channel is connected to the main star wheel. The transmission shaft is clamped on the cam disc. The plug pressing head is arranged on the transmission shaft. The transmission shaft rotates along the axial direction of the cam disc to drive the plug pressing head to suck the plug from the plug feeding module and press the plug onto the packaged bottle on the main star wheel.

[0005] Further, the transmission shaft and the main star wheel rotate synchronously.

[0006] Further, the transmission shaft comprises a mandrel, a sliding sleeve, a retainer, a follow-up bearing, and a vacuum pipe joint. The retainer is arranged on the top of the mandrel. The follow-up bearing and the vacuum pipe joint are arranged on the retainer. The follow-up bearing is clamped on the cam disc. The sliding sleeve is sleeved on the mandrel. The sliding sleeve and the mandrel can slide relative to each other. A guide groove is arranged on the sliding sleeve. A round head flat key is arranged on the mandrel. The round head flat key is located in the guide groove. The plug pressing head is arranged on the bottom of the mandrel.

[0007] Furthermore: the cam disk includes a disk body, on which a track groove is provided, the follower bearing is engaged in the track groove, the track groove is divided into multiple segments, each segment having different height dimensions, and the drive shaft drives the stopper head to complete the bottle stopper sealing work under the action of the multiple segments of the track groove.

[0008] Furthermore, the track groove is divided into a plug-removing section, a plug-pressing section, a holding section, and a plug-releasing section.

[0009] Furthermore: the pressure plug head is screwed to the spindle via an anti-over-torsion device, and a buffer spring and a limiting ring are fitted on the spindle, with the buffer spring located between the limiting ring and the anti-over-torsion device.

[0010] Furthermore: the pressure head includes a pressure head shaft, a plug, and negative pressure air holes. The pressure head shaft has an internal cavity, and a receiving groove is provided at the bottom of the pressure head shaft. A groove is provided in the center of the receiving groove, and a sealing gasket is provided at the opening of the groove. The plug is installed in the groove, and the sealing gasket is located on the outer periphery of the plug. Multiple negative pressure air holes are provided, which are used to connect the cavity and the receiving groove. The multiple negative pressure air holes are circumferentially distributed on the outer periphery of the groove.

[0011] Furthermore, the sidewall of the receiving groove is provided with a plurality of circumferentially distributed ball-head spring plungers, which are used to extend into the receiving groove, and the length of their extension into the receiving groove is adjustable.

[0012] Furthermore, the edges of the feeding star wheel, the main star wheel, and the output star wheel are respectively provided with multiple bottle feeding grooves for accommodating bottle holders.

[0013] Furthermore: Above the star wheel is a stopper disc that rotates synchronously with it, and the edge of the stopper disc is provided with multiple notches for accommodating bottle stoppers.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By setting a fixed cam disc, the drive shaft is mounted on the cam disc, and the stopper head is mounted on the drive shaft. The drive shaft can rotate along the axial direction of the cam disc. The feed star wheel, main star wheel, and output star wheel are rotatable, and the drive shaft and main star wheel rotate synchronously. During operation, the packaging bottle is placed on the bottle holder. For each bottle holder fed into the main star wheel by the feed star wheel, the main star wheel outputs one bottle holder into the output star wheel. Simultaneously, the stopper feeding module delivers a stopper. When the stopper is delivered to a position close to the main star wheel, it is driven by the cam disc... The drive shaft drives the stoppering head to pick up the stopper. Then, the transmission shaft rotates to the lower position of the cam plate, driving the stoppering head to move downward. At the same time, the bottle holder carries the packaged bottle from the infeed channel into the main star wheel. At this time, the stoppering head presses the stopper onto the bottle mouth. Then, the transmission shaft rotates to the higher position of the cam plate, driving the stoppering head to move upward. At the same time, the main star wheel transports the packaged bottle with the stopper to the outfeed star wheel, which then transports it to the next process. This achieves fully automatic stoppering, meeting a stable stoppering speed of up to 180 bottles per minute and improving production efficiency.

[0016] 2. By placing the packaging bottles on bottle holders for transport, the square structure of the bottle holders allows for stable transport of the packaging bottles and enables the positioning of the packaging bottles to ensure that the bottles are facing the same direction.

Detailed Implementation

[0027] Figures 1 to 9 This is a schematic diagram of an embodiment of a rotary shaped bottle stopper provided by the present invention. It includes a cam disc 1, a drive shaft 2, a stopper head 3, an infeed screw 4, an infeed star wheel 5, a main star wheel 6, an outfeed star wheel 7, and a stopper delivery module 8. The infeed star wheel 5, main star wheel 6, and outfeed star wheel 7 are rotatably mounted. The infeed screw 4 is connected to the infeed star wheel 5. A bottle guide plate 9 is provided between the infeed star wheel 5 and the outfeed star wheel 7. The infeed star wheel 5 and the bottle guide plate 9 cooperate to form an infeed channel 11, which connects to the main star wheel 6. The outfeed star wheel 7 and the bottle guide plate 9 cooperate to form an outfeed channel 12, which connects to the main star wheel 6. The drive shaft 2 is mounted on the cam disc 1, and the stopper head 3 is mounted on the drive shaft 2. The drive shaft 2 rotates along the axial direction of the cam disc 1 to drive the stopper head 3 to pick up the stopper 37 from the stopper delivery module 8 and press the stopper 37 onto the packaging bottle 39 on the main star wheel 6.

[0028] The drive shaft 2 and the main star wheel 6 rotate synchronously. The cam disk 1 remains stationary.

[0029] The infeed star wheel 5 and the outfeed star wheel 7 rotate at the same speed.

[0030] The drive shaft 2 includes a spindle 13, a sliding sleeve 14, a cage 15, a follower bearing 16, and a vacuum tube connector 17. The cage 15 is located on the top of the spindle 13. The follower bearing 16 and the vacuum tube connector 17 are respectively located on the cage 15, and the follower bearing 16 is locked onto the cam disk 1. The sliding sleeve 14 is fitted onto the spindle 13, and the sliding sleeve 14 and the spindle 13 can slide relative to each other. The sliding sleeve 14 is provided with a guide groove 18, and the spindle 13 is provided with a round-headed flat key 19, which is located in the guide groove 18. The pressure plug head 3 is located at the bottom of the spindle 13.

[0031] Guide groove 18 is an elongated groove.

[0032] The round-headed flat key 19 is fixed to the spindle 13 by bolts.

[0033] The cam disk 1 includes a disk body 20, on which a track groove 21 is provided. The follower bearing 16 is engaged in the track groove 21. The track groove 21 is divided into multiple segments, each segment having different heights. Under the action of the multiple segments of the track groove 21, the drive shaft 2 drives the stopper head 3 to complete the sealing work of the bottle stopper 37 of the packaging bottle 39.

[0034] The track groove 21 is divided into a plug removal section, a plug pressing section, a holding section, and a plug loosening section.

[0035] The compression section is the lowest section of the track groove 21, and the loosening section is the highest section of the track groove 21.

[0036] During operation, the packaging bottle 39 is placed on the bottle holder 36. The feeding screw 4 feeds the bottle holder 36 to the feeding star wheel 5. The feeding star wheel 5 feeds the bottle holder 36 to the main star wheel 6. The stopper delivery module 8 delivers the stopper 37. For every bottle holder 36 fed into the main star wheel 6 by the feeding star wheel 5, the main star wheel 6 outputs a bottle holder 36 to the output star wheel 7. At the same time, the stopper delivery module 8 delivers a stopper 37.

[0037] When the bottle stopper 37 is conveyed to a position close to the main star wheel 6, the drive shaft 2 is driven by the cam disk 1 to drive the stopper head 3 to pick up the bottle stopper 37. Then, the follower bearing 16 rotates toward the stoppering section of the track groove 21. The retainer 15 drives the spindle 13 to move the stopper head 3 downward. At the same time, the bottle holder 36 carries the packaged bottle 39 from the inlet channel 11 into the main star wheel 6. At this time, the stopper head 3 presses the bottle stopper 37 onto the bottle mouth of the packaged bottle 39. Then, the follower bearing 16 rotates toward the loosening section of the track groove 21. The retainer 15 drives the spindle 13 to move the stopper head 3 upward. At the same time, the main star wheel 6 conveys the packaged bottle 39 with the bottle stopper 37 to the outlet star wheel 7 and then to the next process through the outlet channel 12.

[0038] As the follower bearing 16 moves up and down through the cage 15 to drive the spindle 13 under the action of the track groove 21, the round-headed flat key 19 moves up and down along the guide groove 18.

[0039] The pressure head 3 is screwed to the spindle 13 via the anti-over-torsion device 22. The spindle 13 is fitted with a buffer spring 23 and a limiting ring 24, and the buffer spring 23 is located between the limiting ring 24 and the anti-over-torsion device 22.

[0040] The pressure head 3 includes a pressure head shaft 25, a plug 26, and negative pressure air holes 27. The pressure head shaft 25 has an internal cavity 28, and a receiving groove 29 is provided at the bottom of the pressure head shaft. A groove 30 is provided in the center of the receiving groove 29, and a sealing gasket 31 is provided at the opening of the groove 30. The plug 26 is installed in the groove 30, and the sealing gasket 31 is located on the outer periphery of the plug 26. Multiple negative pressure air holes 27 are provided, which are used to connect the cavity 28 and the receiving groove 29. The multiple negative pressure air holes 27 are distributed in a circular pattern on the outer periphery of the groove 30.

[0041] When the stopper head 3 picks up the bottle stopper 37, the plug 26 blocks the through hole 38 in the center of the bottle stopper 37. The cavity 28 of the stopper head 3 is connected to the receiving groove 29 through the negative pressure air hole 27. It is connected to a vacuum generating device (not shown) through the vacuum tube connector 17, so that the cavity 28 of the stopper head 3 generates negative pressure, thereby generating negative pressure in the receiving groove 29 to adsorb the bottle stopper 37 in the receiving groove 29. The sealing gasket 31 can improve the airtightness and prevent air leakage between the plug 26 and the through hole 38 of the bottle stopper 37.

[0042] When the drive shaft 2 drives the stopper head 3 to move downward and press the stopper 37 on the stopper head 3 onto the bottle mouth of the packaging bottle 39, it breaks the vacuum in the cavity 28 and the receiving groove 29, so that the receiving groove 29 loosens the stopper 37, thereby pressing the stopper 37 onto the bottle mouth of the packaging bottle 39.

[0043] The sidewall of the receiving groove 29 is provided with a plurality of circumferentially distributed ball spring plungers 32, which are used to extend into the receiving groove 29 and the length of their extension into the receiving groove 29 is adjustable.

[0044] The length of the ball-head spring plunger 32 extending into the receiving groove 29 can be adjusted according to the size of the bottle stopper 37, so as to further press the bottle stopper 37 into the receiving groove 29 through the ball-head spring plunger 32, thereby improving the stability of the stopper pressing and picking up the bottle stopper 37.

[0045] Multiple bottle delivery slots 33 for accommodating bottle holders 36 are respectively provided on the edges of the inlet star wheel 5, the main star wheel 6, and the outlet star wheel 7.

[0046] The bottle holder 36 has a square structure, or the bottle holder 36 may have a circular structure.

[0047] Above the star wheel 7 is a stopper plate 34 that rotates synchronously with it, and the edge of the stopper plate 34 is provided with multiple notches 35 for accommodating bottle stoppers 37.

[0048] When the stopper 37 is being transported, the stopper 37 is placed in the notch 35.

[0049] The above detailed description is a specific description of feasible embodiments of the present invention. These embodiments are not intended to limit the patent scope of the present invention. All equivalent implementations or modifications that do not depart from the present invention should be included in the patent scope of this case.
