[0002] As people's living standards continue to improve, their requirements for the packaging of food, medicine, and other commodities are becoming increasingly stringent. To prevent food from spoiling quickly within a certain timeframe, manufacturers need to use vacuum packaging machines to remove excess air from glass food bottles, effectively inhibiting the growth of certain bacteria. Current vacuum packaging machines require pre-capping before vacuuming; that is, the cap is screwed onto the bottle body beforehand, but not completely sealed to facilitate air extraction without removing the cap. The existing pre-capping method primarily relies on manual capping, where the cap is manually placed on the bottle body, and then the bottle is conveyed to the vacuuming station for vacuuming. The existing pre-capping method has the following shortcomings:

[0003] 1) Manual capping is inefficient and affects the production progress of subsequent vacuum packaging processing;

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-7This utility model provides an automatic capping machine for bottle capping. The automatic capping machine includes a working platform 1 and a bottle body rotating structure 2, a cap feeding structure 3, and a cap screwing and lifting structure 4 installed on the working platform 1. The cap screwing and lifting structure 4 is located above the bottle body rotating structure 2 and the cap feeding structure 3. The cap feeding structure 3 is located on one side of the bottle body rotating structure 2. The cap screwing and lifting structure 4 includes a fixed base 42 and a cap screwing and suction mechanism 41, a rotary power mechanism 43, a slide rail 44, and a connecting rod 45 installed on the fixed base 42. The slide rail 44 is installed above the bottle body rotating structure 2 and the cap feeding structure 3. The connecting rod 45 is located outside the slide rail 44. One end of the connecting rod 45 is connected to the rotary power mechanism 43, and the other end of the connecting rod 45 is connected to the upper end of the cap screwing and suction mechanism 41. The cap screwing and suction mechanism 41 is connected to the rotary power mechanism 43 through the connecting rod 45. The automatic capping machine includes a bottle conveying structure 5, which is installed above the working platform 1 and located on the left and right sides of the bottle rotating structure 2. Specifically, the automatic capping machine includes a PLC controller 6, which is installed above the working platform 1 and located in front of the bottle rotating structure 2. The automatic capping machine uses a cap suction mechanism 41 to suction the bottle cap 8 from the cap feeding structure 3. A rotating power mechanism 43 drives a connecting rod 45 to rotate, causing the connecting rod 45 to move the cap suction mechanism 41 along a slide rail 44. This allows the cap suction mechanism 41, holding the bottle cap 8, to move to the bottle rotating structure 2, whereby the bottle cap 8 is placed on the top of the bottle body 7 of the rotating structure 2. The cap suction mechanism 41 then rotates to fasten the bottle cap 8 to the opening at the top of the bottle body 7, but the bottle cap 8 is not completely sealed to the top of the bottle body 7, facilitating subsequent vacuuming operations to remove air from the bottle. The automatic capping machine of this utility model can automatically feed the bottle body 7, automatically feed the cap, and automatically cap the bottle body 7. It has a high degree of automation, improves the efficiency of cap feeding and capping, eliminates the need for manual capping operation, reduces labor costs, reduces labor input, and improves production efficiency.

[0030] In this embodiment of the invention, the bottle conveying structure 5 includes a bottle conveyor belt 51 and a conveyor motor 52. The conveyor motor 52 is mounted on one side of the bottle conveyor belt 51 and is connected to the bottle conveyor belt 51 in a transmission manner. The bottle turntable 21 of the bottle rotating structure 2 is located in the middle of the bottle conveyor belt 51. The bottle conveyor belt 51 is driven to run by the conveyor motor 52. Specifically, the bottle conveyor belt 51 includes a feeding conveyor section 511 and a discharging conveyor section 512. The discharging conveyor section 512 and the feeding conveyor section 511 are located on the left and right sides of the bottle turntable 21, respectively. The feeding conveyor section 511 of the bottle conveyor belt 51 is connected to the right side of the bottle turntable 21, and the discharging conveyor section 512 of the bottle conveyor belt 51 is connected to the left side of the bottle turntable 21.

[0031] The cap feeding structure 3 of this utility model includes a cap feeding turntable 31, a cap feeding working plate 32, and a turntable rotation cylinder 33. The cap feeding working plate 32 is located between the cap feeding turntable 31 and the turntable rotation cylinder 33. The cap feeding turntable 31 is installed above the cap feeding working plate 32, and the turntable rotation cylinder 33 is installed below the cap feeding working plate 32. The rotating part of the cylinder of the turntable rotation cylinder 33 passes through the cap feeding working plate 32 and is connected to the middle of the cap feeding turntable 31. One side of the cap feeding turntable 31 is also connected to a cap feeding conveyor belt, and the other side of the cap feeding turntable 31 is located below the cap screwing and cap picking structure 4. The cap feeding conveyor belt transports the bottle caps 8 to the cap feeding turntable 31. The turntable rotation cylinder 33 rotates to drive the bottle caps 8 on the cap feeding turntable 31 to rotate, so that the cap feeding turntable 31 rotates the bottle caps 8 to below the cap screwing and cap suction mechanism 41.

[0032] In a specific implementation of this utility model embodiment, the cap-screwing and cap-suction mechanism 41 includes a cap-suction head 411, a rotary drive assembly 412, a movable support assembly 413, and a sliding connecting shaft 414. The movable support assembly 413 is located outside the slide rail 44. One end of the sliding connecting shaft 414 is fixed to the top of the movable support assembly 413, and one end of the sliding connecting shaft 414 is also connected to the other end of the connecting rod 45. The other end of the sliding connecting shaft 414 is provided with a sliding end that cooperates with the slide rail 44. The rotary drive assembly 412 is movably disposed on the movable support assembly 413, and the cap-suction head 411 is fixed below the rotary drive assembly 412. The capping and suction mechanism 41 uses a suction head 411 to hold the bottle cap 8 at the cap delivery structure 3. A rotary power mechanism 43 drives a connecting rod 45 to rotate. During rotation, the connecting rod 45 drives the sliding connecting shaft 414 of the capping and suction mechanism 41, along with the movable support assembly 413 fixed to the sliding connecting shaft 414, the rotary drive assembly 412, and the suction head 411, to move along the slide rail 44. This allows the suction head 411 to slide from the cap delivery structure 3 to the bottle body rotating structure 2. The suction head 411 is slightly rotated by the rotary drive assembly 412, so that the bottle cap 8 is pre-attached to the top of the bottle body 7. The pre-attached bottle cap 8 only covers the opening at the top of the bottle body 7 and does not completely seal the bottle body 7, facilitating subsequent vacuuming operations. The movable support assembly 413 includes two movable guides... The system includes two movable guide rails 4131 and a connecting seat 4132. The top ends of the two movable guide rails 4131 are connected to the connecting seat 4132. One end of the sliding connecting shaft 414 is fixed to the connecting seat 4132 at the top ends of the two movable guide rails 4131. The rotary drive assembly 412 is movably mounted on the two movable guide rails 4131. The rotary drive assembly 412 includes a fixed slider seat 4121 that cooperates with the movable guide rails 4131, a rotary cylinder 4122, and a rotary shaft 4123. The rotary cylinder 4122 is mounted above the fixed slider seat 4121, and the rotary shaft 4123 is located below the fixed slider seat 4121. The piston rod of the rotary cylinder 4122 passes through the fixed slider seat and is connected to one end of the rotary shaft 4123. The other end of the rotary shaft 4123 is connected to the suction cap head 411. The rotary cylinder 4122 is activated to rotate, which in turn drives the rotary shaft 4123 to rotate. During the rotation of the rotary shaft 4123, the cap suction head 411 rotates, thereby causing the cap suction head 411 to slightly rotate the bottle cap 8, making it easier for the bottle cap 8 to be fastened to the opening of the bottle body 7. The rotary power mechanism 43 of this utility model includes a rotary motor 431 and a motor output shaft 432 fixed on the rotary motor 431. The motor output shaft 432 of the rotary motor 431 is connected to one end of the connecting rod 45.

[0033] In a specific implementation, the fixing base 42 of this utility model includes a fixing plate 421, a protective cover 422, and a receiving chamber. The protective cover 422 is located in front of the fixing plate 421 and covers the outer periphery of the fixing plate 421. The receiving chamber is located inside the protective cover 422. The rotary motor 431 is fixed to the rear end of the fixing plate 421. The slide rail 44, the cap-screwing and cap-suction mechanism 41, and the connecting rod 45 are all located in the receiving chamber of the fixing base 42. The slide rail 44 is fixed to the front end of the fixing plate 421. The cap-screwing and cap-suction mechanism 41 and the connecting rod 45 are located at the front end of the fixing plate 421. The fixing plate 421 has an opening in the middle. The motor output shaft 432 of the rotary motor 431 passes through the opening of the fixing plate 421 and is connected to one end of the connecting rod 45 at the front end of the fixing plate 421. By setting up the protective cover 422, the slide rail 44 and the linkage rod 45 inside the fixed base 42 can be protected. At the same time, the safety of the automatic capping machine during operation is improved, and the staff will be prevented from accidentally touching the slide rail 44 during operation, thus improving the safety of operation.

[0034] In this embodiment, the slide rail 44 is configured as a U-shaped structure, with the opening of the slide rail 44 facing the cap feeding turntable 31 of the cap feeding structure 3 and the bottle body rotating structure 2's bottle body rotating turntable 21. The slide rail 44 is U-shaped, which facilitates the movement of the sliding connecting shaft 414 of the capping and suction mechanism 41, the movable support assembly 413 fixed to the sliding connecting shaft 414, and the rotary drive assembly 412 along the slide rail 44. This allows the suction head 411 on the rotary drive assembly 412 to move to the cap feeding turntable 31, thus facilitating the suction head 411 to hold the bottle cap 8 on the cap feeding turntable 31. It also facilitates the rotation of the rotary motor 431 to move the suction head 411 and the rotary drive assembly 412 holding the bottle cap 8 from the cap feeding structure 3 to the bottle body turntable 21, so that the bottle cap 8 held by the suction head 411 can be placed on the bottle body 7 of the bottle body turntable 21. This allows the rotary drive assembly 412 to drive the bottle cap 8 to rotate slightly, so that the bottle cap 8 is slightly fastened to the top of the bottle body 7.

[0035] In a specific implementation of this utility model, the bottle rotating structure 2 includes a bottle turntable 21 and a turntable motor 22. The turntable motor 22 is located below the bottle turntable 21, and the motor shaft of the turntable motor 22 is connected to the middle of the bottle turntable 21. The circumference of the bottle turntable 21 is provided with several bottle-holding slots 23 for accommodating the bottle body 7. The bottle body 7 is placed in the bottle-holding slots 23 on the circumference of the bottle turntable 21. The turntable motor 22 is started to rotate, thereby driving the bottle turntable 21 to rotate as well. This allows the bottle turntable 21 to rotate the bottle body 7 to a position below the cap-screwing mechanism 41, so that the cap 8 held by the cap-screwing head 411 of the cap-screwing mechanism 41 can be fastened to the top of the bottle body 7, thus achieving automatic pre-capping of the bottle body 7.

[0036] In a specific implementation, the bottle body rotation structure 2 of this utility model includes a protective railing 24, which is installed on the outer side of the bottle body turntable 21. The protective railing 24 can prevent the bottle body 7 from being thrown off the bottle body turntable 21 when the rotation speed of the bottle body turntable 21 is too high, thereby improving safety.

[0037] The working principle of this automatic capping machine includes the following process:

[0038] First, the conveyor motor 52 drives the bottle body conveyor belt 51 to run. The feeding conveyor section 511 of the bottle body conveyor belt 51 transports the bottle body 7 to be capped to the bottle slot 23 on the left edge of the bottle body turntable 21. The cap feeding conveyor belt will transport the bottle cap 8 to the cap feeding turntable 31 of the cap feeding structure 3.

[0039] Secondly, the rotary cylinder 33 rotates to drive the cap delivery rotary table 31 and the bottle cap 8 on it to rotate, so that the cap delivery rotary table 31 rotates the bottle cap 8 to the bottom of the cap screwing and suction mechanism 41. The rotary motor 22 rotates to drive the bottle body rotary table 21 to rotate, so that the bottle body rotary table 21 rotates the bottle body 7 to the bottom of the cap screwing and suction mechanism 41.

[0040] Next, the cap suction head 411 picks up the bottle cap 8 from the cap feeding turntable 31 of the cap feeding structure 3. The rotary motor 431 drives the connecting rod 45 to rotate. During the rotation, the connecting rod 45 will drive the sliding connecting shaft 414 and the movable support assembly 413 fixed to the sliding connecting shaft 414, the rotary drive assembly 412, and the cap suction head 411 to move along the slide rail 44, so that the cap suction head 411 slides from above the cap feeding turntable 31 to the bottle body rotating structure 2.

[0041] Then, the rotary cylinder 4122 of the rotary drive assembly 412 rotates to drive the rotary shaft 4123 to rotate. During the rotation, the rotary shaft 4123 will drive the cap suction head 411 to rotate, thereby causing the cap suction head 411 to drive the bottle cap 8 to rotate slightly, so that the bottle cap 8 is attached to the top of the bottle body 7.

[0042] Finally, the turntable motor 22 drives the bottle body turntable 21 to rotate, rotating the capped bottle body 7 to the discharge conveyor section 512 of the bottle body conveyor belt 51, and the discharge conveyor section 511 conveys the capped bottle body 7 out.

[0043] The automatic capping machine of this utility model can achieve automatic feeding, automatic cap feeding, automatic capping, and automatic material feeding. It has a high degree of automation, improves the efficiency of cap feeding and capping, eliminates the need for manual operation, and improves processing and production efficiency.

[0044] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
