Description

Technical Field

[0001] This invention relates to the field of packaging technology, and in particular to an automatic bottle-closing machine. Background Technology

[0002] To facilitate carrying, retailers typically use interlocking clips to connect multiple beverage bottles together, allowing customers to carry multiple bottles simultaneously. Common interlocking clips include double and quadruple clips. To facilitate the assembly of multiple beverage bottles and interlocking clips, assembly machines have been developed. For example, Chinese patent (CN221454942U) discloses a four-hole handle assembly machine, which automates manual assembly and significantly improves production efficiency. However, during assembly, the four-hole handle moves from the bottle cap side towards the bottle neck. The bottle cap must pass through the holes in the handle, and since the diameter of the bottle cap is generally larger than the bottle neck diameter, considerable force is required to complete this process, inevitably leading to damage to the handle. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides an automatic bottle-closing machine, which has the advantages of improving product qualification rate and assembly stability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An automatic bottle-closing machine, comprising: A conveying device for conveying containers and groups of containers, the group of containers being a plurality of containers connected together by interlocking links; and, A bottle-locking device is used to connect the interlocking links and a plurality of containers conveyed by the conveying device into the container group; wherein the interlocking links are an even number of interlocking links and connect an even number of containers; The bottle-closing device includes: A fastener feeding mechanism is used to provide the fasteners; The interlocking assembly mechanism connects the interlocking mechanism to several containers by horizontally inserting the interlocking mechanism into the bottleneck of the container; and, The interlocking feeding mechanism is used to transfer the interlocking from the interlocking feeding mechanism to the interlocking assembly mechanism.

[0005] By adopting the above technical solution, the container bottleneck is horizontally squeezed into the snap-fit ​​part of the interlocking assembly mechanism, achieving a lateral connection between the interlocking and the container. Compared with the existing technology of inserting from above the bottle cap, the horizontal squeezing method does not require the hole of the interlocking to extend beyond the larger diameter bottle cap; the snap-fit ​​part of the interlocking only needs to elastically open and cover the relatively smaller diameter bottleneck to complete the connection. This lateral assembly method significantly reduces the mechanical stress on the interlocking during assembly, effectively preventing breakage, deformation, or wear during assembly, thus improving product qualification rate and assembly stability. Simultaneously, the horizontal squeezing assembly method makes the fit between the snap-fit ​​part of the interlocking and the bottleneck more tight and reliable, reducing the likelihood of loosening during subsequent handling and transportation of the container assembly.

[0006] Optionally, the interlocking feeding mechanism, the interlocking unloading mechanism, and the interlocking assembly mechanism are distributed from top to bottom; the interlocking unloading mechanism includes an interlocking gripping component, an interlocking lifting component, and a flipping component; the interlocking gripping component includes interlocking claws; the interlocking lifting component drives the interlocking gripping component to move vertically up and down; the flipping component is used to flip the interlocking gripping component during the lifting and lowering process; when the interlocking gripping component is at the uppermost position, the claws of the interlocking claws face upwards; when the interlocking gripping component is at the lowermost position, the claws of the interlocking claws face downwards.

[0007] By adopting the above technical solution, the interlock feeding mechanism, interlock unloading mechanism, and interlock assembly mechanism are arranged vertically from top to bottom, making full use of gravity-assisted interlock transfer, reducing the horizontal space occupied, and making the overall structure more compact. The interlock lifting component drives the interlock gripping component to reciprocate vertically, and works with the flipping component to realize the automatic flipping of the interlock claws: when the gripping component rises to the top, the claws face upward to pick up the interlock from the interlock feeding mechanism; when the gripping component descends to the bottom, the claws face downward to accurately place the interlock into the interlock assembly mechanism. This design achieves efficient vertical transfer of interlocks, avoids complex horizontal conveying mechanisms, simplifies the mechanical structure, and ensures stability and positioning accuracy during the interlock transfer process.

[0008] Optionally, the interlocking gripping assembly further includes a rotatably mounted connecting spindle; the interlocking claw is radially fixed to the connecting spindle; the flipping assembly includes a vertically mounted guide flipping component and a guide drive block fixed to the end of the connecting spindle; the guide flipping component includes a first guide bar, a flip drive seat, and a second guide bar distributed from top to bottom; the guide drive block has a first guide surface, a flip drive part, and a second guide surface; the first guide surface and the first guide bar cooperate to realize the vertical movement of the guide drive block; the flip drive part and the flip drive seat cooperate to realize the flipping of the guide drive block by 180 degrees; the second guide surface and the second guide bar cooperate to realize the vertical movement of the guide drive block.

[0009] By adopting the above technical solution, the connecting spindle serves as the rotational support for the interlocking jaws, enabling the jaws to rotate around their axis. The guide drive block moves synchronously with the connecting spindle. After the interlocking jaws achieve interlocking gripping, when its first guide surface engages with the first guide bar, the guide drive block and the connecting spindle maintain vertical downward movement. When the flipping drive unit enters the flipping drive seat, the gear segment meshes with the drive column, driving the guide drive block to rotate 180 degrees during the continued descent, realizing the jaws' attitude change from upward to downward. Subsequently, the second guide surface engages with the second guide bar, and the guide drive block continues to move vertically downward, accurately placing the interlocking jaws in the designated position. This flipping mechanism utilizes the mechanical cooperation between the guide flipping component and the guide drive block to complete the three actions of gripping, flipping, and placing in a single lifting motion, eliminating the need for an independent rotary drive source. It features a simple and reliable structure and continuous, efficient operation.

[0010] Optionally, the flip drive base has a plurality of vertically distributed cylindrical drive columns; the flip drive part is a gear segment coaxial with the connecting main shaft; the gear segment cooperates with the plurality of drive columns.

[0011] By adopting the above technical solution, when the cylindrical drive column meshes with the gear teeth of the gear segment, the contact is a line contact or an approximate point contact, resulting in low frictional resistance and smooth transmission. Multiple drive columns are vertically distributed to ensure that at least two drive columns are always meshing with the gear segment during the flipping process, guaranteeing the continuity and stability of the flipping process and avoiding jamming or tooth skipping. The gear segment is coaxially set with the connecting spindle, allowing the flipping torque to be directly transmitted to the connecting spindle, resulting in high transmission efficiency and precise control of the flipping angle.

[0012] Optionally, the gear segment has a number of gear slots equal to the number of drive columns; the gear slots near the first guide surface and the gear slots near the second guide surface each have a guide portion.

[0013] By adopting the above technical solution, the gear slots and drive columns correspond one-to-one, ensuring the accuracy of meshing; the guide part provides a buffered transition when the gear segments enter and disengage from the meshing state, reducing impact and noise and extending the service life of the mechanism; the guide part facilitates the smooth entry and disengagement of the gear segments, making the entire flipping process smoother and more reliable.

[0014] Optionally, the interlocking assembly mechanism includes a separating component and a pair of bottle-locking components; the separating component is located between the pair of bottle-locking components; the containers are respectively located between the separating component and the pair of bottle-locking components; the separating component is used to drive the containers on both sides to separate from each other; the pair of bottle-locking components are used to drive the containers on the corresponding sides to move closer to the separating component; the interlocking has a C-shaped snap-fit ​​portion and the opening direction of the snap-fit ​​portion faces the bottle-locking component on the corresponding side.

[0015] By adopting the above technical solution, the separating component and a pair of bottle-locking components form a symmetrical clamping layout, with the containers to be assembled located on both sides of the separating component. During operation, the separating component first drives the containers on both sides to separate from each other, creating a sufficient gap between the two containers for the interlocking to enter. Subsequently, the pair of bottle-locking components drive the containers on the corresponding sides to move closer to the separating component, and the containers gradually enter the opening of the C-shaped snap fastener, finally completing the snap-fit ​​assembly between the interlocking and the container. The opening of the C-shaped snap fastener faces the bottle-locking component, allowing the container to slide smoothly into the snap fastener during the approach process. The assembly action is smooth and natural, avoiding interference and collision between the snap fastener and the container.

[0016] Optionally, the separation assembly includes a separation center shaft, a pair of separation drive plates, and a pair of separation drive components; the axial direction of the separation center shaft is parallel to the conveying direction of the conveying device; the middle of the pair of separation drive plates is rotatably connected to the separation center shaft and is arranged crosswise; the separation drive components and the separation drive plates correspond one-to-one and drive the separation drive plates to rotate.

[0017] By adopting the above technical solution, the separation center shaft serves as a fixed fulcrum, and a pair of separation drive plates form a scissor-like cross structure. When a pair of separation drive components drive a pair of separation drive plates to rotate around the separation center shaft, the upper ends of the pair of separation drive plates swing in opposite directions, thereby simultaneously pushing the containers on both sides to separate from each other. The cross structure can minimize the space occupied when a pair of separation drive plates are close to each other, reducing the impact on the horizontally conveyed containers. The axial direction of the separation center shaft is parallel to the conveying direction, making the force direction of the separation drive plates perpendicular to the container arrangement direction, resulting in high separation efficiency and minimal interference with container positioning.

[0018] Optionally, the bottle-closing assembly includes a horizontally movable bottle-closing pusher and a pusher driving component for driving the bottle-closing pusher to move horizontally.

[0019] By adopting the above technical solution, the bottle-closing pusher, as the execution component that directly acts on the container, has a precisely controllable horizontal movement stroke; the drive component of the pusher can adopt a cylinder, electric cylinder, or servo motor in combination with a lead screw, etc., and can be flexibly selected according to the production cycle and container specifications.

[0020] Optionally, the interlocking assembly mechanism further includes a pair of blocking components; the pair of blocking components are located at the ends of the bottle-locking device and respectively block the forward conveying of the container on the corresponding side.

[0021] By adopting the above technical solution, the blocking component forms a positioning stop at the end of the bottle-closing device, so that the container arriving at the assembly station stops accurately in the preset position, avoiding overshoot caused by inertia or conveyor belt friction; a pair of blocking components correspond to the containers on both sides respectively, and can be controlled independently or act synchronously to adapt to the assembly needs of container groups of different specifications; the blocking component can adopt various forms such as lifting baffle, rotating baffle arm or pneumatic stop, which coordinates with the running rhythm of the conveying device to ensure that the container is fixed in position during the assembly process, thereby improving assembly accuracy and success rate.

[0022] Optionally, the conveying device includes a first conveying mechanism, a second conveying mechanism, and a third conveying mechanism arranged in sequence; the bottle-locking device is located at the second conveying mechanism; the first conveying mechanism conveys containers in a single row at its front end and in a double row at its rear end; the second conveying mechanism conveys containers in a double row; the conveying speed of the first conveying mechanism is less than the conveying speed of the second conveying mechanism; the conveying speed of the second conveying mechanism is less than the conveying speed of the third conveying mechanism.

[0023] By adopting the above technical solution, the three-stage conveying mechanism forms a conveying rhythm with increasing speed. The first conveying mechanism uses a single row of conveyors at the front end to achieve initial sorting and feeding of containers, and at the end, it switches to double-row conveying through a bottle-separating mechanism to prepare for the subsequent assembly of even-numbered interlocking containers. The increasing speed design creates a tension effect between the front and rear conveying mechanisms, and the distance between adjacent containers gradually increases, which facilitates the separation of containers by the separation components and avoids the accumulation and compression of containers during the conveying process. The bottle-locking device is set at the second conveying mechanism, where the containers have already been arranged in double rows with appropriate spacing, which is conducive to the separation action of the separation components and facilitates the close assembly of the bottle-locking components. The high-speed conveying of the third conveying mechanism quickly moves the assembled container group out of the bottle-locking station, making room for the entry of subsequent container groups and ensuring the continuity and efficiency of production.

The container 11 includes a bottle body and a bottle cap. The upper end of the bottle body is the bottle neck 111. The upper side of the bottle neck 111 is a connecting thread for connecting with the bottle cap. A circular stop ring 112 is provided at the connection between the connecting thread and the bottle neck 111. The outer diameter of the stop ring 112 is larger than the diameter of the bottle neck 111. The fastener 12 is a four-way fastener. The fastener 12 includes four C-shaped snap-fit ​​parts 121, four connecting parts 122 respectively connected between adjacent snap-fit ​​parts 121, and a handle part 123 connected between the upper middle parts of the opposite connecting parts 122. The openings of two adjacent snap-fit ​​parts 121 face the same side, and the openings of the other two snap-fit ​​parts 121 face the opposite side. The fastener 12 is made of plastic and is integrally injection molded. In other embodiments, the interlocking buckle 12 can be a double interlocking buckle, in which case the interlocking buckle 12 has two C-shaped snap-fit ​​parts 121, a connecting part 122 connecting adjacent snap-fit ​​parts 121, and a handle part 123 fixed on the connecting part 122. The openings of the two snap-fit ​​parts 121 are far apart from each other. In addition, as long as the interlocking buckle has a symmetrical even number of snap-fit ​​parts 121, corresponding connecting parts 122 and handle parts 123, it is suitable for this automatic bottle clamping machine; in addition, the container 11 includes a bottle containing liquids such as beverages or milk.

[0041] refer to Figure 3 The automatic bottle-closing machine includes a conveying device 20 and a bottle-closing device 30; the conveying device 20 is used to convey containers 11 and container groups 10; the bottle-closing device 30 is used to connect the four containers 11 conveyed by the interlocking device 12 and the conveying device 20 into a container group 10.

[0042] refer to Figure 3 The conveying device 20 includes a first conveying mechanism 21, a second conveying mechanism 22, and a third conveying mechanism 23 arranged sequentially; the bottle-locking device 30 is located at the second conveying mechanism 22; the first conveying mechanism 21 conveys containers in a single row at its front end and in a double row at its rear end; the second conveying mechanism 22 conveys containers in a double row; the conveying speed of the first conveying mechanism 21 is less than the conveying speed of the second conveying mechanism 22; the conveying speed of the second conveying mechanism 22 is less than the conveying speed of the third conveying mechanism 23. All three conveying mechanisms—the first conveying mechanism 21, the second conveying mechanism 22, and the third conveying mechanism 23—are conveyor belt mechanisms.

[0043] refer to Figure 3The bottle-closing device 30 includes a bottle-closing frame 40, a connecting feeding mechanism 50, a connecting unloading mechanism 60, and a connecting assembly mechanism 70. The bottle-closing frame 40 includes a bottle-closing base 41 and a bottle-closing bracket 42. The bottle-closing bracket 42 is fixed to the upper end of the bottle-closing base 41. The second conveying mechanism 22 is fixed to the bottle-closing base 41 and passes through the bottle-closing bracket 42. To ensure double-row conveying of containers 11 at the end of the first conveying mechanism 21, a partition plate 43 is fixed to the side wall of the bottle-closing bracket 42 near the first conveying mechanism 21. The partition plate 43 divides the end of the first conveying mechanism 21 into two channels, allowing containers 11 to enter the bottle-closing bracket 42 in two rows, facilitating assembly into container groups 10.

Within 110, the four latching parts 121 of the interlocking buckle 12 are vertically fitted onto the four interlocking buckle feeding guide posts 512. To prevent the interlocking buckle 12 from falling off due to its own weight, the bottom of the interlocking buckle feeding guide post 512 is formed with a coaxially arranged circular stop piece 5121. The diameter of the stop piece 5121 is slightly larger than the inner diameter of the latching part 121. Under normal conditions, the four latching parts 121 of the interlocking buckle 12 are blocked by their respective stop pieces 5121. However, when the interlocking buckle 12 is subjected to a certain downward pulling force, the latching part 121, being made of plastic and C-shaped, will deform to pass over the stop piece 5121, thus completing the feeding of the interlocking buckle 12. During operation, the four interlocking buckle feeding guide posts 512 perform the function of storing materials. Several interlocking buckles 12 stacked one on top of the other are fitted onto the four interlocking buckle feeding guide posts 512, and the handle part 123 is located on the lower side of the four connecting parts 122.

In other embodiments, the overall length of the second link 64 is adjustable. The specific structure of the second link 64 is as follows: the second link 64 includes an intermediate connecting rod and a pair of hinged rods respectively screwed to both ends of the intermediate connecting rod. The end of the hinged rod away from the intermediate connecting rod is hinged to the first link 63 or the lower link 651. In this way, by adjusting the overall length of the pair of second links 64, the gripping position of the interlocking gripping assembly 67 can be changed, thereby ensuring the accuracy of the interlocking 12 gripping.

[0046] refer to Figure 7 The interlocking gripping assembly 67 includes a connecting main shaft 671 and four interlocking claws 672; a connecting seat is fixed at the upper end of the lower connecting rod 651; the two ends of the connecting main shaft 671 are rotatably connected to a pair of connecting seats by bearings; the axial direction of the connecting main shaft 671 is parallel to the conveying direction of the second conveying mechanism 22; the four interlocking claws 672 are radially fixed to the connecting main shaft 671 and distributed along the axial direction of the connecting main shaft 671; the interlocking claws 672 correspond one-to-one with the interlocking feeding assembly 51 and are used to grip the lowermost interlocking 12 stored on the corresponding interlocking feeding assembly 51; the interlocking claws 672 grip the interlocking 12 by gripping the handle 123.

[0047] refer to Figures 7-9 The flipping assembly 68 includes a guide flipping component 682 and a guide drive block 681. The guide flipping component 682 is fixed to the side wall of the bottle holder 42. The guide drive block 681 is fixed to the end of the connecting spindle 671 and cooperates with the guide flipping component 682. The guide flipping component 682 includes a first guide bar 6821, a flipping drive seat 6822, and a second guide bar 6823 distributed from top to bottom. The first guide bar 6821, the flipping drive seat 6822, and the second guide bar 6823 are all fixed to the side wall of the bottle holder 42 by screws. The first guide bar 6821 and the second guide bar 6823 are rectangular strips arranged vertically in the length direction. The flipping drive seat 6822 includes a drive seat body 68221 with a horizontally open cross-section in the shape of a "U" and five cylindrical drive columns 68222 vertically distributed at the opening of the drive seat body 68221. The drive columns 68222 are arranged horizontally in the axial direction. The guide drive block 681 has a first guide surface 6811, a flip drive part 6812, and a second guide surface 6813; the first guide surface 6811 and the second guide surface 6813 are parallel to each other and the flip drive part 6812 is located between the first guide surface 6811 and the second guide surface 6813; the flip drive part 6812 is a gear segment coaxial with the connecting spindle 671 and this gear segment has five gear slots 6814 that mate with the drive column 68222.

[0048] refer to Figure 8 When the guide drive block 681 engages with the first guide bar 6821, the flip drive unit 6812 is located at the lower end of the guide drive block 681, and the first guide surface 6811 abuts against the vertical sidewall of the first guide bar 6821; Reference Figure 9 When the guide drive block 681 engages with the second guide bar 6823, the flip drive part 6812 is located at the upper end of the guide drive block 681 and the second guide surface 6813 is in contact with the vertical side wall of the second guide bar 6823. During operation, the interlocking lifting assembly 61 drives the connecting spindle 671 to descend. Since the first guide surface 6811 is in contact with the vertical sidewall of the first guide bar 6821, the guide drive block 681 and the connecting spindle 671 will only move vertically and will not rotate. As the guide drive block 681 continues to descend, the uppermost drive column 68222 enters the outermost gear groove 6814. With the continuous meshing of the gear groove 6814 and the drive column 68222, the guide drive block 681 rotates 180 degrees counterclockwise, that is, the connecting spindle 671 rotates 180 degrees counterclockwise. The interlocking pawl 672 changes from pawl facing up to pawl facing down. Then, the outermost gear groove 6814 separates from the lowermost drive column 68222, and the second guide surface 6813 is in contact with the second guide bar 6823. At this time, the guide drive block 681 and the connecting spindle 671 will only move vertically and will not rotate. Both the guide drive block 681 and the connecting spindle 671 can only move vertically at the end of the lifting process, which is conducive to accurately gripping and placing the interlocking buckle 12, improving assembly quality and efficiency.

[0049] To ensure that the outermost gear groove 6814 interacts with the drive column 68222, guide portions 6815 are formed at both ends of the flip drive unit 6812. Guide surfaces 6816 are formed on the side wall of the guide portion 6815 near the outermost gear groove 6814. When the flip drive unit 6812 is about to engage with the five drive columns 68222, the guide portion 6815 first inserts into the gap between the vertical cross-section of the five drive columns 68222 and the vertical surface of the first guide bar 6821, or inserts into the gap between the vertical cross-section of the five drive columns 68222 and the vertical surface of the second guide bar 6823. Then, under the action of the guide surface 6816, the drive column 68222 enters the outermost gear groove 6814. Since the drive column 68222 is fixed, the guide drive block 681 rotates.

[0050] refer to Figure 10 and Figure 11 The interlocking assembly mechanism 70 includes a separating component 71 and a pair of bottle-locking components 72, wherein the separating component 71 is located between the pair of bottle-locking components 72; there are eight containers 11 between the separating component 71 and the pair of bottle-locking components 72.

The ends of the pair of upper push plates 7242 that are close to each other extend beyond the ends of the pair of lower push plates 7241 that are close to each other. The lower push plate 7241 is used to push the bottle body of container 11, and the upper push plate 7242 is used to push the bottle cap of container 11. In this way, the movement of container 11 is more stable and accurate, which is conducive to the connection of container 11 and buckle 12. To better accommodate container 11, the horizontal position of the upper push plate 7242 relative to the lower push plate 7241 is adjustable. The specific structure is as follows: the upper push plate 7242 is formed with at least two elongated adjustment holes perpendicular to the conveying direction of the second conveying mechanism 22. Several adjustment bolts are screwed onto the lower push plate 7241. The adjustment bolts correspond one-to-one with the adjustment holes, and the screws of the adjustment bolts pass through the adjustment holes on the corresponding sides. When adjustment is required, the adjustment bolts are loosened to separate the heads of the adjustment bolts from the upper push plate 7242. After adjustment, the adjustment bolts are tightened to press the heads of the adjustment bolts against the upper push plate 7242.

[0052] refer to Figures 10-12 To prevent the container 11 from stopping at the bottle-closing position, a pair of push plates 7241 are respectively connected to blocking components 73 near the end of the bottle-closing device. The blocking component 73 includes a blocking drive 731 and a blocking block 732. The blocking drive 731 is fixed on the push plate 7241 on the corresponding side. The blocking drive 731 is an electric cylinder, but other linear drive elements such as a pneumatic cylinder can also be used. The blocking block 732 is fixed on the piston rod of the blocking drive 731. The blocking block 732 is L-shaped and its surface in contact with the container 11 is the blocking contact surface 7320. The blocking contact surface 7320 is an L-shaped surface with a middle arc transition, and the arc of the middle transition part is adapted to the diameter of the bottle body of the container 11.

[0053] refer to Figure 13The separation assembly 71 includes a separation central shaft 711, a pair of separation drive plates 712, and a pair of separation drive components 713; a pair of intermediate fixing blocks are fixed on the bottom surface of the bottle holder 42; both ends of the separation central shaft 711 are respectively fixed on the pair of intermediate fixing blocks, and the axial direction of the separation central shaft 711 is parallel to the conveying direction of the second conveying mechanism 22; the separation drive plate 712 includes a separation main plate 7121, three separation rotating frames 7122, and a separation drive connecting plate 7123; the length direction of the separation main plate 7121 and the length direction of the separation drive connecting plate 7123 are parallel to the conveying direction of the second conveying mechanism 22; the middle part of the separation rotating frame 7122 is coaxially rotatably connected to the separation central shaft 711; the upper end of the separation rotating frame 7122 is connected to the separation main plate 7121. The lower end is connected by screws, and the lower end is connected to the separation drive connecting plate 7123 by screws; a pair of separation drive plates 712 are arranged crosswise; the separation drive plate 712 corresponds one-to-one with the separation drive component 713; the separation drive component 713 includes a separation drive element 7131, which is an electric cylinder, but other linear drive elements such as a pneumatic cylinder can also be used; the piston rod end of the separation drive element 7131 is fixed with a hinge connecting block 7133, and a hinge connecting frame 7132 is fixed on the housing; the hinge connecting frame 7132 is hinged to the bottom surface of the bottle holder 42; the hinge connecting block 7133 is hinged to the separation drive connecting plate 7123; in order to avoid the second conveying mechanism 22, a pair of separation drive components 713 are hidden inside the conveyor belt of the second conveying mechanism 22. During operation, when the piston rods of a pair of separation drive components 7131 extend, the separation main plates 7121 of a pair of separation drive plates 712 move closer to each other; when the piston rods of a pair of separation drive components 7131 retract, the separation main plates 7121 of a pair of separation drive plates 712 move further apart, thereby pushing open the eight containers 11 on both sides.

[0054] In other embodiments, an intermediate barrier frame 74 is provided between a pair of bottle-locking assemblies 72; the intermediate barrier frame 74 includes a pair of blocking support plates 741 distributed along the conveying direction of the second conveying mechanism 22 and a blocking upper strip 742 fixed between the upper ends of the pair of blocking support plates 741; the pair of blocking support plates 741 and the blocking upper strip 742 form a downward-facing "U" shape, and the separation assembly 71 is located between the pair of blocking support plates 741 and the blocking upper strip 742; the upper end of the blocking upper strip 742 is processed into a flat surface, and the interlocking feeding mechanism 60 can press the bottom surface of the extracted interlocking 12 against the flat surface of the blocking upper strip 742, so that the interlocking 12 has greater strength and better positional stability, which is conducive to the subsequent insertion of the container 11 into the buckle part 121. In this way, the intermediate barrier frame 74 not only serves to block the containers 11 on both sides, but also serves as an auxiliary support for the interlocking 12.

[0055] The working principle is as follows: A single row of containers 11 is conveyed forward by the first conveying mechanism 21. Since the end of the first conveying mechanism 21 is equipped with a partition plate 43, the containers 11 become a double row and leave the first conveying mechanism 21, reaching the second conveying mechanism 22. The second conveying mechanism 22 conveys the double row of containers 11 forward. During this process, a pair of blocking components 73 start to work. A pair of blocking blocks 732 move closer to each other to block the double row of containers 11, so that there are eight containers 11 on each side of the separating component 71. At this time, the interlocking feeding mechanism 60 has taken four interlocking clips 12 from the interlocking feeding mechanism 50, and the four interlocking clips 12 are located above the sixteen containers 11. At this time, the separating component 71... The working mechanism moves the containers 11 on both sides outward, then the separating component 71 returns to its original position. Next, the interlocking feeding mechanism 60 drives the four interlocking components 12 to descend a certain distance, so that the opening of the snap-fit ​​part 121 of the interlocking component 12 is aligned with the neck 111 of the corresponding container 11. Then, a pair of bottle-closing components 72 move the containers 11 on both sides of the separating component 71 inward. During this process, the neck 111 of the container 11 squeezes through the opening of the snap-fit ​​part 121 and enters the snap-fit ​​part 121, thus completing the assembly of the interlocking component 12 and the container 11. Then, a pair of bottle-closing components 72 return to their original position, and a pair of blocking components 73 also return to their original position. Then, the second conveying mechanism 22 conveys the four container groups 10 to the third conveying mechanism 23.

[0056] Example 2: The difference between Example 2 and Example 1 is as follows: (Refer to...) Figure 14 The lower push plate 7241 includes a lower push plate seat 7243 and a lower push plate body 7245; the lower push plate seat 7243 is fixedly connected to a pair of drive linkages 723; the lower push plate body 7245 moves elastically horizontally on the end face of the lower push plate seat 7243 away from the pair of drive linkages 723; the blocking assembly 73 and the upper push plate 7242 are fixed on the lower push plate seat 7243; the elastic connection structure of the lower push plate body 7245 is as follows: a number of horizontally distributed horizontal guide rods 7247 are fixed on the end face of the lower push plate body 7245 near the lower push plate seat 7243, one end of the horizontal guide rod 7247 passes vertically through the lower push plate seat 7243 and is fixed with a stop plate 7248, and a compression spring 7249 is sleeved on the horizontal guide rod 7247; the two ends of the compression spring 7249 abut against the end faces of the lower push plate body 7245 and the lower push plate seat 7243 that are close to each other.

[0057] refer to Figure 14 Seven horizontally distributed bottle abutment seats 7244 are fixed on the end face of the push plate seat 7243 near the push plate body 7245; the end face of the bottle abutment seat 7244 away from the push plate seat 7243 is formed into an arc surface that matches the bottle body of the container 11; seven horizontally distributed horizontal perforations 7246 are formed on the push plate body 7245; the horizontal perforations 7246 correspond one-to-one with the bottle abutment seats 7244; the seven push plate bodies 7245 and the blocking blocks 732 correspond to eight containers 11 respectively.

[0058] Under normal conditions, the bottle body abutment 7244 is located between the lower push plate body 7245 and the lower push plate seat 7243. During operation, when a pair of bottle-locking push parts 724 approach each other, the lower push plate body 7245 first contacts the container 11. As the pair of bottle-locking push parts 724 continue to approach, the friction of the container 11 overcomes the spring force of the compression spring 7249, and the lower push plate body 7245 moves towards the lower push plate seat 7243. During this process, the bottle body abutment 7244 passes through the horizontal through hole 7246 of the lower push plate body 7245 and contacts the bottle body of the container 11. Due to the existence of the arc surface of the bottle body abutment 7244, the bottle body abutment 7244 can correct the position of the corresponding container 11. When the bottle body of the container 11 is in contact with the arc surface of the bottle body abutment 7244, the upper push plate 7242 simultaneously abuts against the bottle cap of the container 11. This makes the movement direction of the container 11 more accurate, which is beneficial for the assembly with the interlocking buckle 12.

[0059] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
