[0021] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0022] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0023] See Figures 1-7 As shown, this embodiment discloses a lid separation and pressing device 6, which includes: a lid storage mechanism 61, a lid splitting mechanism 62, and a lid pressing mechanism 63 arranged sequentially from top to bottom; the lid storage mechanism 61 is provided with a receiving space 611 for vertically stacking lids 30, and the receiving space 611 has an opening at the bottom; the lid splitting mechanism 62 is disposed at the bottom of the receiving space 611 for releasing a single lid 30 to the lid pressing mechanism 63; the lid pressing mechanism 63 is provided with a pressing area 631 for placing a storage container 20, and the lid pressing mechanism 63 is used to drive a single lid 30 to press onto the storage container 20.

[0024] Understandably, the lids 30 are stacked and stored in the lid storage mechanism 61. When a packaging operation is required, the lid separating mechanism 62 is controlled to separate one lid 30 from the stacked lids 30 and let it fall onto the top of the storage container 20 in the pressing area 631. Then, the lid pressing mechanism 63 is controlled to press the lid 30 down to the top opening of the storage container 20, so that the lid 30 and the storage container 20 achieve an interference fit.

[0025] The lid separation and pressing device 6 in this embodiment, through the cooperation of the lid storage mechanism 61, the lid separation mechanism 62, and the lid pressing mechanism 63, realizes the storage, single lid release, and automatic pressing of the lid 30, replacing the traditional manual lid-pressing operation, breaking the manual dependence in the packaging process, realizing the fully automated operation, improving the overall automation level of the equipment, improving the efficiency of food packaging, avoiding the risk of cross-contamination, ensuring the cleanliness and hygiene of the equipment and food, and improving the level of food safety.

[0026] Specifically, the capping mechanism 63 includes: a bracket 632, a lower pressure plate 633, and a telescopic component 634; the telescopic component 634 is movably connected to the bracket 632, and the lower pressure plate 633 is connected to the telescopic component 634; the telescopic component 634 is used to drive the lower pressure plate 633 to move horizontally to enter or leave the pressing area 631; the lifting component 635 is used to drive the telescopic component 634 to perform a lifting action, so that the lower pressure plate 633 moves away from the pressing area 631 or presses the cap 30 down onto the storage container 20. In this embodiment, the cap storage mechanism 61 is fixedly connected to the top of the cap separating mechanism 62, and the bracket 632 is fixedly connected to the cap separating mechanism 62. When the lid needs to be lowered, the telescopic component 634 drives the lower pressure plate 633 to move horizontally away from the pressing area 631, leaving clearance so that the lid 30 can fall unimpeded above the storage container 20. When the lid needs to be pressed, the telescopic component 634 drives the lower pressure plate 633 to move horizontally, so that it enters the pressing area 631 and is directly above the lid 30. Then, driven by the lifting component 635, the lower pressure plate 633 descends until it contacts the lid 30 and presses it down to the opening of the storage container 20. After pressing is completed, the lifting component 635 and the telescopic component 634 reset, waiting for the next lid-lowering action. Through the coordinated action of the telescopic component 634 and the lifting component 635, the lower pressure plate 633 moves horizontally in and out of the pressing area 631 and vertically lifts and lowers the cover, achieving a compound movement. This allows for precise pressing of the cover 30 without manual intervention, effectively replacing manual operation and improving the automation level of the pressing process. At the same time, it ensures that the lower pressure plate 633 can accurately align the cover 30 with the storage container 20, guaranteeing pressing accuracy and consistency, and avoiding pressing failure caused by cover 30 offset.

[0027] Specifically, there are two sets of lower pressure plates 633, two telescopic components 634, and two lifting components 635. The two telescopic components 634 are symmetrically arranged and movably connected to the bracket 632. The two lower pressure plates 633 are symmetrically arranged and connected to the two telescopic components 634 respectively. The two lifting components 635 are symmetrically arranged and connected to the two telescopic components 634 respectively. The symmetrical arrangement of the two sets of lower pressure plates 633, telescopic components 634, and lifting components 635 ensures that the pressure of the lower pressure plates 633 on the cover 30 is applied evenly from both sides, avoiding uneven force on the cover 30 due to unilateral pressure, which could cause deformation or displacement. This improves the stability and reliability of the pressing process. At the same time, the synchronous operation of the two sets of components enhances the coordination of the pressing process and further improves the pressing efficiency.

[0028] Specifically, the telescopic assembly 634 includes: a limiting post 6341, a connecting block 6342, a connecting rod 6343, and a guide member 6344; one end of the limiting post 6341 is fixedly connected to the bracket 632, and the other end extends downward from the bracket 632; the connecting block 6342 has a vertically extending first limiting hole (not shown in the figure) and a horizontally extending second limiting hole (not shown in the figure), the limiting post 6341 passes through the first limiting hole, the connecting rod 6343 is horizontally arranged, and passes through the second limiting hole; the lower pressure plate 633 is fixedly connected to one end of the connecting rod 6343, and the guide member 6344 is located on the side of the connecting rod 6343 away from the lower pressure plate 633, for driving the connecting rod 6343 to move along the second limiting hole towards the pressing area 631. Preferably, the limiting post 6341 and the connecting rod 6343 are arranged through the connecting block 6342. When the guide member 6344 is subjected to an external force, it applies a thrust to the connecting rod 6343, pushing the connecting rod 6343 to move towards the pressing area 631 along the horizontal direction of the second limiting hole. The connecting rod 6343 drives the fixedly connected lower pressure plate 633 to move synchronously. When the lifting assembly 635 is working, the connecting block 6342 can move along the vertical direction of the limiting post 6341. Since the limiting post 6341 passes through the first limiting hole, it can limit the horizontal displacement of the connecting block 6342, ensuring that the connecting block 6342 only moves stably in the vertical direction. Specifically, the telescopic assembly 634 further includes: a first elastic element 6345; the first elastic element 6345 is disposed between the connecting rod 6343 and the guide member 6344, and is used to drive the connecting rod 6343 to move along the second limiting hole in a direction away from the pressing area 631. When the thrust of the guide member 6344 on the connecting rod 6343 disappears, the first elastic element 6345, which is in a compressed state, releases its elastic potential energy and applies a spring force to the connecting rod 6343 in a direction away from the guide member 6344, pushing the connecting rod 6343 to move horizontally along the second limiting hole in a direction away from the pressing area 631, and the connecting rod 6343 drives the lower pressure plate 633 to leave the pressing area 631 simultaneously; when the guide member 6344 applies a thrust to the connecting rod 6343 again, the first elastic element 6345 is compressed, and the connecting rod 6343 overcomes the spring force and moves closer to the pressing area 631. The first elastic element 6345 enables the automatic reset function of the connecting rod 6343, eliminating the need for additional drive components to drive the lower pressure plate 633 away from the pressing area 631, simplifying the structure of the telescopic component 634 and reducing equipment costs; at the same time, the elastic reset method reacts quickly and can quickly drive the lower pressure plate 633 away from the pressing area 631, improving overall work efficiency.

[0029] Specifically, the guide member 6344 is provided with a guide ramp 63441, which slopes downward from top to away from the pressing area 631. The lifting assembly 635 is used to drive the guide member 6344 downward so that the guide ramp 63441 pushes the connecting rod 6343 towards the pressing area 631, or to drive the guide member 6344 upward so that the first elastic member 6345 pushes the connecting rod 6343 away from the pressing area 631. It can be understood that the distance between the top of the guide ramp 63441 and the pressing area 631 is less than the distance between the bottom of the guide ramp 63441 and the pressing area 631. When the lifting assembly 635 drives the guide member 6344 to descend, the guide slope 63441 of the guide member 6344 contacts the connecting rod 6343 and generates relative sliding. During the descent of the guide member 6344, the guide slope 63441 will contact the connecting rod 6343. The guide slope 63441 gradually contacts the connecting rod 6343 from bottom to top and gradually squeezes the connecting rod 6343, generating a horizontal component force on the connecting rod 6343 in the pressing area 631, pushing the connecting rod 6343 to move along the second limiting hole towards the pressing area 631. When the lifting assembly 635 drives the guide member 6344 to rise, the thrust of the guide slope 63441 on the connecting rod 6343 disappears, and the first elastic member 6345 pushes the connecting rod 6343 to move away from the pressing area 631. By utilizing the inclined structure of the guide ramp 63441, the vertical driving force of the lifting component 635 is converted into the horizontal driving force of the connecting rod 6343, so that the telescopic action and the lifting action are achieved in coordination through the same driving component. There is no need to set up a separate driving component for the telescopic action, which simplifies the equipment structure, reduces energy consumption, and ensures the synchronization of the telescopic and lifting actions, thereby improving the smoothness of the capping process.

[0030] Specifically, the guide member 6344 is further provided with a limiting part 63442, which extends horizontally from the top of the guide slope 63441 toward the pressing area 631. More specifically, the limiting part 63442 is movable above the connecting block 6342. When the lifting assembly 635 drives the guide member 6344 to descend to the highest position of the guide slope 63441 and contact the connecting rod 6343, the connecting rod 6343 abuts against the limiting part 63442. The limiting part 63442 generates a vertical blocking force on the connecting rod 6343, preventing the guide member 6344 from continuing to descend and causing the connecting rod 6343 to detach from the top of the guide member 6344. At the same time, it prevents the guide member 6344 from changing direction or colliding with other components due to excessive movement, thus protecting the safety of the equipment components.

[0031] Specifically, a guide rod 6346 is provided at the end of the connecting rod 6343 away from the lower pressure plate 633. The guide rod 6346 is horizontally arranged and perpendicular to the connecting rod 6343. A pulley 6347 is rotatably mounted on the guide rod 6346, and the pulley 6347 is tangent to the guide inclined surface 63441. It can be understood that the pulley 6347 moves between the guide inclined surface 63441 and the limiting part 63442. Preferably, the first elastic member 6345 is sleeved on the outside of the connecting rod 6343 and is located between the connecting block 6342 and the guide rod 6346. When the guide member 6344 descends, the guide ramp 63441 contacts the pulley 6347. Since the pulley 6347 can rotate on the guide rod 6346, the sliding friction between the guide ramp 63441 and the pulley 6347 is converted into rolling friction. The pulley 6347 rolls along the guide ramp 63441, driving the guide rod 6346 and the connecting rod 6343 to move towards the pressing area 631 until the limiting part 63442 abuts against the pulley 6347. During this process, the first elastic member 6345 is compressed. When the guide member 6344 rises, the distance between the connecting rod 6343 and the guide member 6344 increases, and the guide rod 6346 moves away from the pressing area 631 under the elastic action of the first elastic member 6345. The pulley 6347 converts the sliding friction between the guide ramp 63441 and the connecting rod 6343 into rolling friction, significantly reducing the frictional resistance between them, reducing component wear, and extending the service life of the guide 6344 and the connecting rod 6343. At the same time, it makes the lifting and lowering action of the guide 6344 smoother and avoids the action jamming due to excessive frictional resistance. The first elastic element 6345 is sleeved on the outside of the connecting rod 6343, which can limit the deformation direction of the first elastic element 6345, prevent the first elastic element 6345 from shifting laterally, and ensure the stable elastic reset effect.

[0032] In this embodiment, pulley 6347 is a bearing. When guide member 6344 rises and falls, the inner ring of the bearing is fixed relative to guide rod 6346, and the outer ring contacts and rolls with guide inclined surface 63441 or limiting part 63442. The rolling of the outer ring drives the entire bearing to move along guide inclined surface 63441 or limiting part 63442, thereby driving guide rod 6346 and connecting rod 6343 to move synchronously, realizing the horizontal movement and reset of connecting rod 6343. By selecting bearing as pulley 6347, the mature rolling structure of bearing is utilized to ensure the stability and reliability of the rolling process. Compared with ordinary pulley 6347, bearing has stronger load-bearing capacity and lower wear rate, which can adapt to the long-term high-frequency operation requirements of unmanned cooking equipment. At the same time, bearing has a high degree of standardization, making later replacement and maintenance more convenient and reducing equipment maintenance costs.

[0033] Preferably, the telescopic assembly 634 contains two limiting posts 6341, two connecting rods 6343, two first limiting holes, two second limiting holes, and two first elastic elements 6345. The two first limiting holes are symmetrically arranged, the two second limiting holes are symmetrically arranged, the two limiting posts 6341 are respectively inserted through the two first limiting holes, the two connecting rods 6343 are respectively inserted through the two second limiting holes, the two connecting rods 6343 are both connected to the lower pressure plate 633, and the two first elastic elements 6345 are corresponding to the two connecting rods 6343. The two ends of the guide rod 6346 are respectively connected to the two connecting rods 6343. The two limiting posts 6341, in conjunction with the two first limiting holes, vertically guide the connecting block 6342 from both sides, preventing it from tilting during lifting and lowering, thus enhancing its stability. The two connecting rods 6343 jointly drive the lower pressure plate 633, making the force on the lower pressure plate 633 more balanced and preventing it from bending and deforming due to unilateral force. The guide rod 6346 connects the two connecting rods 6343, ensuring that the two connecting rods 6343 move synchronously, further improving the coordination and precision of the telescopic movement.

[0034] Specifically, the lifting assembly 635 includes: a lifting seat 6351, a lifting drive component 6352, a lifting guide rail 6353, a lifting slider 6354, and a second elastic component 6355; the lifting seat 6351 is fixedly connected to the cover-opening mechanism 62, the lifting guide rail 6353 is vertically arranged and fixedly connected to the lifting seat 6351, the lifting slider 6354 is slidably connected to the lifting guide rail 6353, and the guide component 6344 is fixedly connected to the lifting slider 6354; one end of the second elastic component 6355 is connected to the bottom of the limiting post 6341, and the other end abuts against the bottom of the connecting block 6342. The lifting drive component 6352 includes, but is not limited to, a motor and lead screw combination, a cylinder, a hydraulic cylinder, etc. The lifting drive component 6352 drives the lifting slider 6354 to descend vertically along the lifting guide rail 6353. The lifting slider 6354 drives the guide component 6344 to descend synchronously, and the guide component 6344 pushes the connecting rod 6343 to move. At the same time, the connecting block 6342 moves downward along the limiting post 6341 as the guide component 6344 descends, and the second elastic component 6355 is compressed. When the lifting drive component 6352 drives the lifting slider 6354 to rise, the guide component 6344 rises synchronously, and the second elastic component 6355 releases its elastic potential energy, pushing the connecting block 6342 to rise along the limiting post 6341, assisting the connecting block 6342 to reset, and reducing the load on the lifting drive component 6352. The cooperation between the lifting guide rail 6353 and the lifting slider 6354 precisely limits the lifting trajectory of the guide member 6344, ensuring that the guide member 6344 moves only vertically and stably, avoiding deviation during lifting and lowering, and ensuring the accuracy of the telescopic action; the second elastic member 6355 provides auxiliary elastic force for the rise of the connecting block 6342, reducing the driving force requirement of the lifting drive member 6352, saving energy, and at the same time reducing the impact when the connecting block 6342 rises, protecting the contact part between the limit post 6341 and the connecting block 6342.

[0035] Specifically, the lid separation and pressing device 6 further includes: a clamping mechanism 64; the clamping mechanism 64 is disposed in the pressing area 631 and is used to clamp the storage container 20; the clamping mechanism 64 includes: two clamping blocks 641 and an opening and closing component 642; the two clamping blocks 641 are symmetrically arranged and located below the lid pressing mechanism 63; the opening and closing component 642 is used to drive the two clamping blocks 641 to move closer or further apart to clamp or release the storage container 20. When the storage container 20 containing food is conveyed to the pressing area 631, the opening and closing component 642 is activated, driving the two clamping blocks 641 to move closer to each other in the horizontal direction until the two clamping blocks 641 contact the outer wall of the storage container 20 and apply clamping force, fixing the storage container 20 in the center of the pressing area 631; after the lid is pressed, the opening and closing component 642 drives the two clamping blocks 641 to move further apart, releasing the storage container 20, so that the storage container 20 can be conveyed out of the pressing area 631. The clamping mechanism 64 fixes the storage container 20 with two clamping blocks 641 to prevent the pressure of the lower pressure plate 633 from causing the storage container 20 to shift or tip over during the capping process, ensuring that the cap 30 can be accurately pressed into the opening of the storage container 20 and improving the pressing accuracy.

[0036] Specifically, the opening and closing assembly 642 includes: a driving wheel 6421, a driven wheel 6422, a timing belt 6423, two mounting blocks 6424, and an opening and closing drive member 6426. The driving wheel 6421 and the driven wheel 6422 are rotatably connected to the cap-opening mechanism 62 or the cap-pressing mechanism 63. The timing belt 6423 is sleeved around the driving wheel 6421 and the driven wheel 6422. The two mounting blocks 6424 are respectively fixedly connected to both sides of the timing belt 6423. The opening and closing drive member 6426 is used to drive the driving wheel 6421 to rotate. The two clamping blocks 641 are respectively fixedly connected to the two mounting blocks 6424. In this embodiment, the opening and closing assembly 642 also includes two mounting plates 6425. The mounting plates 6425 are fixedly connected to the cap-pressing mechanism 63 and extend downward from the cap-pressing mechanism 63. The driving wheel 6421 and the driven wheel 6422 are respectively rotatably connected to the ends of the two mounting plates 6425 away from the cap-pressing mechanism 63. When the storage container 20 needs to be clamped, the opening / closing drive 6426 is activated, driving the drive wheel 6421 to rotate. The drive wheel 6421 drives the driven wheel 6422 to rotate synchronously via the timing belt 6423. Since the two mounting blocks 6424 are fixed on both sides of the timing belt 6423, the rotation of the timing belt 6423 will cause the two mounting blocks 6424 to move in opposite directions, thereby causing the two clamping blocks 641 connected to them to move closer to each other until the storage container 20 is clamped. When the container needs to be released, the opening / closing drive 6426 drives the drive wheel 6421 to rotate in opposite directions, and the timing belt 6423 causes the two mounting blocks 6424 and the clamping blocks 641 to move away from each other, completing the release action. The timing belt 6423 transmission can ensure the synchronicity of the movement of the two clamping blocks 641, avoid the clamping blocks 641 from shifting and causing the storage container 20 to be clamped crookedly, ensure the accurate position of the container when capping, and reduce the number of drive components, thereby reducing the cost of the clamping mechanism 64.

[0037] Specifically, the opening and closing assembly 642 further includes: two opening and closing seats 6427, two opening and closing guide rails 6428, and two opening and closing sliders 6429; the two opening and closing seats 6427 are symmetrically arranged, and the two opening and closing guide rails 6428 are symmetrically arranged; the opening and closing seats 6427 are fixedly connected to the capping mechanism 63, the opening and closing guide rails 6428 are horizontally arranged, the opening and closing sliders 6429 are slidably connected to the opening and closing guide rails 6428, and the two clamping blocks 641 are respectively fixedly connected to the two opening and closing sliders 6429. The cooperation between the opening and closing guide rails 6428 and the sliders can precisely limit the movement trajectory of the clamping blocks 641, ensuring that the clamping blocks 641 always move closer to or further away from the storage container 20 in the horizontal direction, improving the accuracy of the clamping position; at the same time, the sliding cooperation between the sliders and the guide rails can reduce the frictional resistance of the clamping blocks 641 during movement, making the clamping action smoother, reducing the load on the opening and closing assembly 642, and extending its service life.

[0038] Specifically, each of the two clamping blocks 641 has a clamping groove 6411 on one side that is close to each other. The clamping groove 6411 is arc-shaped. The two clamping blocks 641 are close to each other to clamp the storage container 20 with a circular horizontal cross-section. The outward-curved edge of the top of the storage container 20 abuts against the top of the clamping block 641. When the clamping blocks 641 are close to each other, the arc-shaped clamping groove 6411 will gradually fit against the outer wall of the storage container 20 with a circular horizontal cross-section. As the clamping blocks 641 continue to move, the clamping force of the clamping groove 6411 on the storage container 20 gradually increases until the container is fixed. At the same time, the outward-curved edge of the top of the storage container 20 will naturally abut against the top of the clamping block 641, forming a vertical limit to prevent the storage container 20 from moving upward due to the downward pressure of the lower pressure plate 633 when the cap is pressed. The arc-shaped clamping groove 6411 can increase the contact area between the clamping block 641 and the storage container 20, improve the clamping stability, and prevent the storage container 20 from slipping or rotating during the capping process.

[0039] Specifically, the lid-separating mechanism 62 includes: a rotary drive 621 and a plurality of separating blocks 622; the plurality of separating blocks 622 are arranged in a circumferential array at the bottom opening of the receiving space 611, and the outer periphery of the separating blocks 622 is provided with a spiral guide groove 6221; the top opening of the guide groove 6221 faces the center of the receiving space and is used to receive the edge of the lid 30; the edge of the top opening of the guide groove 6221 forms a locking part (not shown), which is used to restrict the lid 30 from entering the guide groove 6221; the rotary drive 621 is used to drive the separating blocks 622 to rotate, so as to drive the lid 30 in the guide groove 6221 into the pressing area 631, or to drive the lid 30 on the locking part into the guide groove 6221. Preferably, the rotary drive 621 is a motor. In the lid storage mechanism 61, among the stacked lids 30, the edge of the bottommost lid 30 initially abuts against the locking part of the separating block 622. When it is necessary to separate the lids, the rotary drive 621 is activated and drives the separating block 622 to rotate around the central axis. The restriction of the locking part on the lid 30 is gradually released as the separating block 622 rotates, and the edge of the lid 30 enters the spiral guide groove 6221 under the action of gravity. As the separating block 622 continues to rotate, the guide groove 6221 will drive the lid 30 to move downward along the spiral trajectory until the lid 30 is separated from the guide groove 6221 and falls into the pressing area 631 from the bottom opening of the receiving space 611. The circumferentially arrayed separating blocks 622, in conjunction with the spiral guide groove 6221, enable precise separation of a single cap 30, preventing multiple caps from falling simultaneously and causing cap separation failure. The locking mechanism prevents the cap 30 from accidentally entering the guide groove 6221 when not in a cap separation state, thus improving the reliability of the cap separation mechanism 62. The rotating drive component 621 uses a motor, which can precisely control the rotation speed of the separating blocks 622, adapting to the cap separation requirements of caps 30 of different specifications and improving cap separation efficiency.

[0040] Specifically, the cover-separating mechanism 62 further includes: a first ring plate 623 and a second ring plate 624; the first ring plate 623 and the second ring plate 624 are symmetrically and parallelly arranged in the vertical direction; the first ring plate 623 is disposed on the second ring plate 624, and both the first ring plate 623 and the second ring plate 624 have a cover-dropping hole 6231 at their center; a number of separating blocks 622 are distributed outside the cover-dropping holes 6231, and the separating blocks 622 are disposed between the first ring plate 623 and the second ring plate 624, and are rotatable relative to the first ring plate 623 and the second ring plate 624; the lifting seat 6351, the opening and closing seat 6427, and the mounting plate 6425 are all fixedly connected to the second ring plate 624. The sandwich structure formed by the first ring plate 623 and the second ring plate 624 provides a stable rotation space for the separating block 622. During the cap-opening operation, the rotary drive 621 drives the separating block 622 to rotate between the first ring plate 623 and the second ring plate 624. The separating block 622 drives the cap 30 to move through the spiral guide groove 6221. When the cap 30 moves to the top of the cap-dropping hole 6231, it falls from the cap-dropping hole 6231 to the pressing area 631. At the same time, the lifting seat 6351, the opening and closing seat 6427, and the mounting plate 6425 are fixed on the second ring plate 624 and maintain a stable position with the second ring plate 624, providing a solid support for the lifting assembly 635 and the opening and closing assembly 642, ensuring that no displacement occurs during the operation of each component. Specifically, the lid storage mechanism 61 includes at least three vertical rods 612. All vertical rods 612 are fixedly connected to the first annular plate 623 and are arranged in a circumferential array around the lid drop hole 6231. All vertical rods 612 enclose a receiving space 611, which communicates with the lid drop hole 6231. In this embodiment, there are four vertical rods 612. It is understood that in other embodiments, the number of vertical rods 612 can be adjusted according to actual needs. In specific implementation, the lid 30 can be inserted not only from the top of the receiving space 611 enclosed by the vertical rods 612, but also from between adjacent vertical rods 612. The lid 30 only needs to be tilted at a certain angle into the receiving space 611 and then placed horizontally, which reduces the difficulty of operation and thus reduces the intensity of manual labor. The lids 30 are stacked vertically under gravity, with the bottom lid 30 contacting the separating block 622 of the lid-separating mechanism 62. During lid separation, the bottom lid 30 is pulled down from the lid drop hole 6231 by the separating block 622, while the top lid 30 moves downward synchronously under gravity to fill the bottom position, awaiting the next lid separation action. Throughout the process, the vertical rods 612 restrict the horizontal displacement of the lids 30, ensuring that the lids 30 are always stacked vertically. The accommodating space 611 enclosed by at least three vertical rods 612 can stably restrict the horizontal displacement of the lids 30, preventing the lids 30 from tilting or tipping over during stacking, and ensuring that the lid-separating mechanism 62 can accurately grasp the bottom lid 30. The vertical rods 612 are fixed to the first ring plate 623 and precisely aligned with the lid drop hole 6231 of the lid-separating mechanism 62, ensuring a smooth falling path for the lids 30.
