Description

TECHNICAL FIELD

[0001] The present application relates to the packaging technical field, specifically relates to a pressing device and a closing device for closing a cover of a connected cover. BACKGROUND

[0002] The connected cover refers to a bottle cap with a cover base connected through a side surface, and the cover base of the connected cover is a sealing component used for complete assembly with a bottle body after closing the cover.

[0003] When the connected cover is closed, the pressing head is pressed for the first time, and the cover base is pressed on the positioning base by the pressing head to avoid the cover base from being lifted when the cover is turned over, and after the cover is turned over to a certain angle, the pressing head needs to be separated from the cover base to avoid the pressing head from hindering the cover from being turned over towards the cover base, and at this time, the cover base is not easy to be lifted due to the need to apply force to the cover towards the cover base, and when the cover is turned over to be close to the cover base, the pressing head is pressed for the second time, and the pressing head is pressed on the cover to press the cover on the cover base, in order to avoid the pressing head from damaging the cover and the cover base, the pressing head needs to be adapted to the thickness of the cover base when pressed for the first time, so that the pressing head is just pressed on the cover base, and the pressing head needs to be adapted to the thickness of the cover and the cover base when pressed for the second time, so that the pressing head is just pressed on the cover, and therefore the height of the pressing head when pressed for the first time and the height of the pressing head when pressed for the second time are different, and the height difference between the pressing head when pressed for the first time and the pressing head when pressed for the second time matches the thickness of the cover.

[0004] At present, the pressing head is usually guided by the groove of the cam plate to be pressed for the first time and the second time, so that the pressing head can be pressed to different heights, and the groove is designed in advance during production, so that the height difference between the pressing head when pressed for the first time and the pressing head when pressed for the second time matches the thickness of the cover, but for different connected covers, the thickness of the cover may be different, and the groove of the cam plate is fixed during production, which can only be adapted to the thickness of the cover, and is difficult to disassemble and assemble on the machine table, which leads to the difficulty in changing the height difference between the pressing head when pressed for the first time and the pressing head when pressed for the second time, and leads to the fact that only one kind of thickness of the cover can be adapted to one device, and the application range is small.

[0049] Please see Figures 1 to 3 One embodiment of the present invention provides a lid closing device, including: a lid pressing device for closing an integral lid.

[0050] The capping device for closing the one-piece cap includes:

[0051] The machine base 10 is equipped with a first track 11 and a second track 12.

[0052] Several positioning seats 20 are movably mounted on the machine base 10. The positioning seats 20 are used to support the cover seat 81 of the integrated cover 80.

[0053] The first slide block 30 is slidably engaged with the first track 11. The first slide block 30 is detachably provided with a pressure head assembly 31, which is movably connected to the first slide block 30.

[0054] The second slide block 40 is slidably engaged with the second track 12, and a pressure rod 41 is detachably provided on the second slide block 40;

[0055] The driving component 50 is driven to the positioning seat 20, the first slide 30, and the second slide 40. Under the drive of the driving component 50, the positioning seat 20 moves sequentially to the first capping station, the flipping station, and the second capping station. Under the drive of the driving component 50, the first slide 30 moves sequentially along the first track 11 to the first capping station, the flipping station, and the second capping station. Under the drive of the driving component 50, the second slide 40 moves sequentially along the second track 12 to the first capping station, the flipping station, and the second capping station.

[0056] When the first slide 30 is in the first capping position, it is in the first capping position relative to the positioning seat 20. The pressure head assembly 31 presses against the cover seat 81 of the integrated cover 80 located on the positioning seat 20, thereby preventing the cover seat 81 of the integrated cover 80 from tilting relative to the positioning seat 20 when the cover is flipped. At this time, since the relative position of the first slide 30 and the positioning seat 20 is fixed, different pressure head assemblies 31 can be replaced according to the different thicknesses of the cover seat 81, so that when the first slide 30 reaches the first capping position, the pressure head assembly 31 can adapt and stably press the cover seat 81 without damaging the cover seat 81.

[0057] In this embodiment, the cap-closing device further includes several cap-flipping rods 60 and a telescopic assembly for driving the cap-flipping rods 60 to move. The cap-flipping rods 60 are disposed on one side of the positioning seat 20. When the positioning seat 20 is in the first cap-pressing position, the cap-flipping rods 60 extend and push the cap 82 of the integrated cap 80 to flip until the cap 82 rotates to one side of the pressing head. The telescopic assembly can be a cylinder, electric cylinder, or hydraulic cylinder, etc., and its output shaft is connected to the cap-flipping rods 60.

[0058] When the first slide 30 is located at the flip-top station, the first slide 30 is in a first clearance position relative to the positioning seat 20. The pressure head assembly 31 disengages from the cover seat 81 of the integrated cover 80 on the positioning seat 20, thereby preventing the pressure head assembly 31 from obstructing the cap 82 of the integrated cover 80 from closing onto the cover seat 81 of the integrated cover 80. In this embodiment, the closing device also includes a flip-top plate 70, which is fixedly mounted on the machine base 10 at the flip-top station. When the positioning seat 20 passes through the flip-top station, the pressure head assembly 31 disengages from the cover seat 81, avoiding the flip-top plate 70, so that the flip-top plate 70 can pass between the positioning seat 20 and the pressure head assembly 31. The cap 82 abuts against the flip-top plate 70. As the positioning seat 20 moves, the cover is restricted by the flip-top plate 70 and flips towards the cover seat 81. When the positioning seat 20 leaves the flip-top station, the cap 82 has flipped to a position close to the cover seat 81, or the cap 82 is approximately closed with the cover seat 81.

[0059] When the second slide 40 is in the second capping position, it is in the second capping position relative to the positioning seat 20. The pressure rod 41 abuts against the pressure head assembly 31 and drives the pressure head assembly 31 to move toward the positioning seat 20, so that the pressure head assembly 31 presses against the cap 82 of the integrated cap 80 located on the positioning seat 20, so that the cap 82 is pressed tightly onto the cap seat 81, thus closing the cap. At this time, since the relative position of the second slide 40 and the positioning seat 20 is fixed, different pressure rods 41 can be replaced according to the different thicknesses of the cap 81, so that when the second slide 40 reaches the second capping position, the pressure rod 41 can push the pressure head assembly 31 to a suitable distance, so that the pressure head assembly 31 can stably press the cap 82 without damaging the cap 82 and the cap seat 81.

[0060] In the prior art, due to the groove limitation of the cam disk 13, the position where the pressure head can descend during the first and second capping is fixed, but the difference in position between the two capping operations is fixed. For example, for the one-piece cap a, the distance between the position of the cap seat 81 of the one-piece cap a that is pressed by the pressure head assembly 31 and the positioning seat 20 is 2cm, and the distance between the position of the cap 82 of the one-piece cap a that is pressed by the pressure head assembly 31 and the positioning seat 20 is 3cm. During the first capping operation, the pressure head moves to a position 2cm away from the positioning seat 20, and the difference in position between the two capping operations is 1cm. During the second capping operation, the pressure head moves to a position 3cm away from the positioning seat 20. However, for the one-piece cap a... The distance between the position of the cover seat 81 of the integrated cover b, where the pressure head assembly 31 presses against the cover, and the positioning seat 20 is 2cm. The distance between the position of the cap 82 of the integrated cover b, where the pressure head assembly 31 presses against the cover, and the positioning seat 20 is 2.9cm. Since the positional difference between the two capping operations is 1cm, the cap 82 will be over-pressed during the second capping operation, causing damage to the cap 82. Moreover, it is not possible to make the pressure head press the cap 82 just right during the second capping operation by replacing the pressure head. The positional difference between the two capping operations can only be adjusted by replacing the cam plate 13. However, the cam plate 13 is large in size and connected to multiple components, making it difficult to disassemble. Therefore, it cannot adapt to caps 82 of different thicknesses.

[0061] In this invention, at the first capping station, the first slide 30 drives the pressure head assembly 31 to press the cap seat 81 of the integrated cap. The pressure head assembly 31 can be replaced to adapt to cap seats 81 of different thicknesses. At the second capping station, the pressure rod 41 on the second slide 40 drives the pressure head assembly 31 to press the cap 82 of the integrated cap. The pressure head assembly 31 can be replaced to adapt to caps 82 of different thicknesses. For example, for one-piece cover a, the distance between the position of the cover seat 81 bearing the pressure of the pressure head assembly 31 and the positioning seat 20 is 2cm, and the distance between the position of the cover cap 82 bearing the pressure of the pressure head assembly 31 and the positioning seat 20 is 3cm. At the first capping station, the pressure head assembly 31 moves to a position 2cm away from the positioning seat 20, and at the second capping station, the pressure head assembly 31 moves to a position 3cm away from the positioning seat 20. For one-piece cover b, the distance between the position of the cover seat 81 bearing the pressure of the pressure head assembly 31 and the positioning seat 20 is 2cm, and the distance between the position of the cover cap 82 bearing the pressure of the pressure head assembly 31 and the positioning seat 20 is 2.9cm. Only by changing different pressure rods 41 can this be achieved. The pressure rod 41 is 0.1cm longer, so that in the second capping station, the pressure rod 41 can push the pressure head assembly 31 to a position relative to the positioning seat 202.9cm. For the one-piece cap c, the distance between the position of the cap seat 81 of the one-piece cap c that is pressed by the pressure head assembly 31 and the positioning seat 20 is 2.1cm, and the distance between the position of the cap 82 of the one-piece cap c that is pressed by the pressure head assembly 31 and the positioning seat 20 is 3.1cm. Different pressure heads can be replaced, so that the pressure head is 0.1cm shorter, so that in the first capping station, the pressure head assembly 31 moves to a position 202.1cm away from the positioning seat, and in the second capping station, the pressure rod 41 pushes the pressure head assembly 31 to still move to a position relative to the positioning seat 203.1cm. In summary, by replacing the pressure head assembly 31 with one of different lengths according to the specifications and shape of the cover 81, the pressure head assembly 31 can stably press against the cover 81. By replacing the pressure rod 41 with one of different lengths according to the specifications and shape of the cap 82, the pressure head assembly 31 can stably press against the cap 82 after the pressure rod 41 pushes it. This can better adapt to the cap 82 and cover 81 of the integrated cover.

[0062] The method of guiding the first slide 30 or the second slide 40 toward the positioning seat 20 can be selected according to actual needs. For example, the first slide 30 or the second slide 40 can be driven by a cylinder to move toward the positioning seat 20. Alternatively, a third track can be set on the machine tool 10 to guide the positioning seat 20 toward the first slide 30 or the second slide 40. In this embodiment, when the first slide 30 moves to the first capping station, the first slide 30 moves relative to the positioning seat 20 to the first capping position under the guidance of the first track 11. When the first slide 30 moves to the capping station, the first slide 30 moves relative to the positioning seat 20 to the first clearance position under the guidance of the first track 11. When the second slide 40 moves to the second capping station, the second slide 40 moves relative to the first slide 30 to the second capping position under the guidance of the first track 11.

[0063] Please see Figure 1 , Figure 4 and Figure 5 The formation of the first track 11 and the second track 12 can be selected according to actual needs. For example, in some optional embodiments, a cam disk 13 is provided on the machine base 10, and the first track 11 and the second track 12 are arranged around the cam disk 13. The drive assembly 50 includes a rotating seat 51 and a drive motor 52. The rotating seat 51 is rotatably mounted on the machine base 10, and the drive motor 52 is drivenly connected to the rotating seat 51. The positioning seat 20, the first slide 30, and the second slide 40 are all connected to the rotating seat 51. In this embodiment, the first track 11 is a first groove formed on the cam disk 13, and the second track 12 is a second groove formed on the cam disk 13. The first slide 30 is provided with a roller movably connected to the first groove, and the second slide 40 is provided with a roller movably connected to the second groove.

[0064] In some optional embodiments, when the first slide 30 is in the second capping position, the first slide 30 is in the third capping position relative to the positioning seat 20. When the first slide 30 is in the third capping position, the distance between it and the positioning seat 20 is greater than the distance between it and the positioning seat 20 when it is in the first capping position. This allows the first slide 30 to move to a suitable position, so that the pressure head assembly 31 is close to the positioning seat 20 without being driven by the first slide 30 to squeeze the cap 82. This makes it convenient for the pressure rod 41 to push the pressure head assembly 31 a short distance to drive the pressure head assembly 31 to press the cap 82. Of course, the first slide 30 can also maintain its position relative to the positioning seat 20 without getting close to the positioning seat 20.

[0065] In some optional embodiments, the positioning seat 20, driven by the driving assembly 50, moves sequentially to the first capping station, the flipping station, the second capping station, and the material feeding station. The first slide 30, driven by the driving assembly 50, moves sequentially along the first track 11 to the first capping station, the flipping station, the second capping station, and the material feeding station. The second slide 40, driven by the driving assembly 50, moves sequentially along the second track 12 to the first capping station, the flipping station, the second capping station, and the material feeding station. In this embodiment, the first track 11 and the second track 12 are circular, and the material feeding station... The material handling station is connected to the first capping station, so that the positioning seat 20, the first slide 30 and the second slide 40 move sequentially along the first capping station, the flipping station, the second capping station and the material feeding station. When the first slide 30 is located at the material feeding station, the first slide 30 is in the second clearance position relative to the positioning seat 20, and a clearance space is formed between the pressure head assembly 31 and the positioning seat 20, so that the integrated cover 80 can be smoothly separated from the positioning seat 20 and the next integrated cover 80 can be smoothly positioned by the positioning seat 20, avoiding the pressure head assembly 31 from hindering the loading and unloading of the integrated cover 80.

[0066] In some optional embodiments, a positioning channel 32 is provided on the first slide 30, and a portion of the second slide 40 or a portion of the pressure rod 41 is movably inserted through the positioning channel 32. The positioning channel 32 can position the second slide 40 or the pressure rod 41 relative to the first slide 30, so that the pressure rod 41 can accurately press against the pressure head assembly 31, and during the movement of the first slide 30 and the second slide 40, the second slide 40 or the pressure rod 41 is prevented from shifting relative to the first slide 30, thereby facilitating the maintenance of the position between the pressure rod 41 and the first slide 30.

[0067] Please see Figure 6 and Figure 7 To prevent the pressure head assembly 31 from impacting the cover seat 81, in some optional embodiments, the first slide 30 is provided with a first guide rail 33 and a first movable seat 34. The first movable seat 34 is slidably engaged with the first guide rail 33. A first elastic element 35 is provided between the first movable seat 34 and the first slide 30. The pressure head assembly 31 is detachably connected to the first movable seat 34, and the pressure head assembly 31 is movably connected to the first movable seat 34. The first slide 30 can drive the pressure head assembly 31 to move through the first movable seat 34.

[0068] When the first slide 30 is in the first capping position, the first slide 30 is in the first capping position relative to the positioning seat 20. The first slide 30 drives the pressure head assembly 31 to press against the cap seat 81 of the integrated cap 80 located on the positioning seat 20 through the first movable seat 34. When the pressure head assembly 31 initially contacts the cap seat 81, the pressure head assembly 31 stops moving. The first slide 30 and the first movable seat 34 cooperate to drive the first elastic member 35 to produce elastic deformation. The elastic force of the first elastic member 35 can play a buffering role, so that the force applied by the first slide 30 to the pressure head assembly 31 through the first movable seat 34 gradually increases, thereby avoiding the pressure head assembly 31 from producing a strong impact on the cap seat 81. In addition, when the pressure head assembly 31 is separated from the cap seat 81, the first elastic member 35 can also play a role in resetting the first movable seat 34.

[0069] Please see Figure 6 and Figure 7 To prevent the pressure head assembly 31 from impacting the cover seat 81, in some optional embodiments, the first movable seat 34 is provided with a second guide rail 341 and a second movable seat 342. The second movable seat 342 is slidably engaged with the second guide rail 341. A second elastic element 343 is provided between the first movable seat 34 and the second movable seat 342. The pressure head assembly 31 is movably connected to the first movable seat 34 through the second movable seat 342. The first slide 30 can drive the second movable seat 342 to move through the first movable seat 34, thereby enabling the first slide 30 to drive the pressure head assembly 31 to move. The pressure head assembly 31 and the second movable seat 342 are detachably connected, thereby enabling the pressure head assembly 31 and the first slide 30 to be detachably assembled.

[0070] When the first slide 30 is in the first capping station, the first slide 30 drives the second movable seat 342 to move through the first movable seat 34, and the second movable seat 342 drives the pressure head assembly 31 to press against the cap seat 81 of the integrated cap 80 located on the positioning seat 20. When the second slide 40 is in the second capping position, the pressure rod 41 abuts against the second movable seat 342 and drives the pressure head assembly 31 toward the positioning seat 20 through the second movable seat 342. When the pressure head assembly 31 initially contacts the cap 82, the pressure head assembly 31 stops moving. The first movable seat 34 and the second movable seat 342 drive the second elastic element 343 to produce elastic deformation. The first movable seat 34 and the second movable seat 342 cooperate to drive the second elastic element 343 to produce elastic deformation. The elastic force of the second elastic element 343 can play a buffering role, so that the force applied by the first movable seat 34 to the pressure head assembly 31 through the second movable seat 342 gradually increases, thereby avoiding the pressure head assembly 31 from producing a strong impact on the cap 82. In addition, when the pressure head assembly 31 is disengaged from the cap 82, the second elastic element 343 can also play a role in resetting the second movable seat 342.

[0071] In this embodiment, the first movable seat 34 is also provided with a first limiting part 344. When the first slide 30 is located at the first pressing station, the first limiting part 344 of the first movable seat 34 is engaged with the side of the second movable seat 342 away from the positioning seat 20 to limit the second movable seat 342 from moving away from the positioning seat 20, thereby maintaining the position of the second movable seat 342 relative to the first movable seat 34 and preventing the second movable seat 342 from moving relative to the first movable seat 34 and affecting the position of the pressing head assembly 31.

[0072] In this embodiment, the first movable seat 34 is also provided with a second limiting part 345. When the first slide 30 is located at the second pressing position, and when the pressing rod 41 pushes the second movable seat 342 to move, the first limiting part 345 is limited and cooperates with the side of the first slide 30 away from the positioning seat 20, so that when the pressing rod 41 pushes the second movable seat 342, it restricts the position of the first movable seat 34 relative to the first slide 30 and does not move, thus avoiding the first movable seat 34 from moving relative to the first slide 30 and affecting the position of the pressing head assembly 31.

[0073] Please see Figure 6 , Figure 7 and Figure 8 To accommodate the shape design of the integrated cover 80 and improve the stability of pressing the integrated cover 80, in some optional embodiments, the pressure head assembly 31 includes a pressure sleeve 311 and a pressure block 312. The pressure block 312 is located inside the pressure sleeve 311, with a portion of the pressure block 312 extending outside the pressure sleeve 311. The pressure sleeve 311 is detachably mounted on the second movable seat 342, thereby achieving a detachable connection with the first slide 30. The second movable seat 342 is provided with a third guide rail 3421 and a movable rod 3422. The movable rod 3422 slides in cooperation with the third guide rail 3421. A third elastic element 3423 is provided between the second movable seat 342 and the movable rod 3422. The pressure head is detachably mounted on the movable rod 3422, thereby achieving a detachable connection with the first slide 30.

[0074] In this embodiment, the shape of the integrated cap 80 is as follows: the top of the cap base 81 is provided with an oil guide ring 83, a cap opening 84 and a sealing plate 85 (refer to a soy sauce bottle cap). The oil guide ring 83 is arranged around the cap opening 84, and the sealing plate 85 is disposed inside the cap opening 84. The sealing plate 85 is provided with a pull ring, which makes it convenient for the user to pull the sealing plate 85 off the cap base 81 to open the cap opening 84. The cap 82 engages with the oil guide ring 83 to close the cap.

[0075] When the first slide block 30 is located at the first capping station, the first slide block 30 drives the second movable seat 342 to move through the first movable seat 34. The second movable seat 342 drives the pressure sleeve 311 and the movable rod 3422 to move toward the positioning seat 20, so that the pressure head on the pressure sleeve 311 and the movable rod 3422 presses against the cap seat 81 of the integrated cap 80 located on the positioning seat 20. The movable rod 3422 and the second movable seat 342 drive the third elastic member 3423 to produce elastic deformation. At the first capping station, the end of the pressure sleeve 311 can abut against the oil guide ring 83 or against the part of the cap seat 81 located near the oil guide ring 83, thereby achieving stable pressing of the cap seat 81. The pressure block 312 extends into the cap opening 84 and fits against the sealing plate 85, further achieving stable pressing of the cap seat 81. When the pressure block 312 presses against the sealing plate 85, the pressure block 312 applies force to the third elastic element 3423 through the movable rod 3422, thereby causing the movable rod 3422 to cooperate with the second movable seat 342, causing the third elastic element 3423 to undergo elastic deformation. The elastic force of the third elastic element 3423 makes the pressure block 312 fit more closely to the sealing plate 85, making the positioning and pressing of the cap seat 81 more stable. In addition, due to the close fit between the pressure sleeve 311 and the cover seat 81, especially with the oil guide ring 83, the cover seat 81 is prevented from wobbling relative to the pressure sleeve 311. Therefore, when the pressure sleeve 311 detaches from the cover seat 81, it may cause the pressure sleeve 311 to pull the cover seat 81 away from the positioning seat 20. However, due to the design of the third elastic element 3423, when entering the flip-cover station, the first slide 30 moves away from the positioning seat 20, causing the first movable seat 34 and the second movable seat 342 to move away from the positioning seat 20. As a result, during the process of the pressure head assembly 31 detaching from the cover seat 81, when the pressure sleeve 311 initially detaches from the cover seat 81, the elastic force of the third elastic element 3423 keeps the pressure head still connected to the sealing plate 85, thus preventing the pressure sleeve 311 from pulling the cover seat 81 to move through the oil guide ring 83. After the pressure sleeve 311 detaches from the cover seat 81 and the oil guide ring 83, the pressure head then detaches from the sealing plate 85, making the separation of the pressure head assembly 31 and the cover seat 81 more stable.

[0076] When the second slide block 40 is in the second capping position, the pressure rod 41 abuts against the second movable seat 342 and drives the second movable seat 342 to move toward the positioning seat 20. The second movable seat 342 drives the pressure sleeve 311 and the movable rod 3422 to move toward the positioning seat 20, so that the pressure heads on the pressure sleeve 311 and the movable rod 3422 press against the cap 82 of the integrated cover 80 located on the positioning seat 20, or so that the pressure block 312 on the movable rod 3422 presses against the cap 82 of the integrated cover 80 located on the positioning seat 20. The pressure sleeve 311 may or may not press against the cap 82. The movable rod 3422 and the second movable seat 342 drive the third elastic member 3423 to produce elastic deformation. The third elastic member 3423 plays a buffering role and also plays a role in resetting the pressure block 312.
