[0038] As attached Figure 1 To be continued Figure 12 As shown,

[0039] A packaging mechanism for guiding products into a packaging box includes a product conveying mechanism and a product guiding mechanism 1;

[0040] The product conveying mechanism includes a feeding conveying mechanism 2, a small batch conveying mechanism 3, a large batch conveying mechanism 4, and a forming conveying mechanism 5 arranged sequentially close to each other. The feeding conveying mechanism 2, the small batch conveying mechanism 3, the large batch conveying mechanism 4, and the forming conveying mechanism 5 have the same conveying direction and maintain synchronous movement. The small batch conveying mechanism 3 is provided with a small batch channel, and the large batch conveying mechanism 4 is provided with a large batch channel. The forming conveying mechanism 5 is provided with a packaging box positioning mechanism.

[0041] The product guiding mechanism 1 includes a first guiding mechanism 8 and a second guiding mechanism 9. The first guiding mechanism 8 is aligned with the conveying direction and is located above the feeding conveying mechanism 2, guiding the product on the feeding conveying mechanism 2. The second guiding mechanism 9 is set at a certain angle to the conveying direction. The front end of the second guiding mechanism 9 is located above the feeding conveying mechanism 2, and the rear end of the second guiding mechanism 9 is located above the large-group conveying mechanism 4. Under the combined action of the first guiding mechanism 8 and the feeding conveying mechanism 2, the product can be conveyed in a straight single row through the conveying channel of the first guiding mechanism 8, and then its direction is changed through the conveying channel of the second guiding mechanism 9 before being conveyed in a single row. The conveying channel width of mechanism 8 is generally wider than the product diameter, ensuring single-row conveying while accommodating the normal conveying of products within a certain size range. The conveying channel width of the second guiding mechanism 9 is slightly larger than the product diameter, and products enter the small grouping channel one by one for individual grouping. To ensure grouping accuracy, the difference between the conveying channel width of the second guiding mechanism 9 and the product diameter is small. Products in multiple adjacent small grouping channels enter the same large grouping channel for multiple groupings. A packaging box 10 is positioned on the forming conveying mechanism 5, with the opening of the packaging box 10 facing the exit of the large grouping channel. Multiple grouped products enter the packaging box 10 through the opening of the packaging box 10. In this embodiment, the large grouping channel can accommodate two products simultaneously.

[0042] The feeding conveyor 2, the small batch conveyor 3, and the large batch conveyor 4 are all chain plate conveyors with flat chain plate surfaces. The chain plate conveyor is an existing structure, and its working principle is that the chain drives the chain plates to rotate, thereby causing the products on the chain plates to move synchronously. The small batch conveyor 3 has multiple small batch stops 6 on its chain plate surface, forming small batch channels between adjacent small batch stops 6. The large batch conveyor 4 has multiple large batch stops 7 on its chain plate surface, forming large batch channels between adjacent large batch stops 7. The directions of both the small batch channels and the large batch channels are perpendicular to the conveying direction of the product conveying mechanism.

[0043] The first guiding mechanism 8 includes multiple parallel first guardrails 8-1, forming a conveying channel between adjacent first guardrails 8-1. Each first guardrail 8-1 is fixed to a connecting rod 8-2, which in turn is fixedly connected to a bracket 11. The bracket 11 is mounted on a hanger 12, which is connected to the frame of the packaging machine via multiple sets of screws 13. The height of the hanger 12 can be adjusted using the screws 13, thereby adjusting the height of the first guardrails 8-1.

[0044] The second guiding mechanism 9 includes multiple parallel and staggered second guardrails 9-1 and adjustable guardrails 9-2. The second guardrails 9-1 and the first guardrails 8-1 are set at a certain angle and fixedly connected. The adjustable guardrails 9-2 are located inside the second guardrails 9-1 and can slide along the side of the first guardrails 8-1. By sliding, the distance between the second guardrails 9-1 and the adjustable guardrails 9-2 can be adjusted to accommodate products of different diameters. During the sliding process, the second guardrails 9-1 and the adjustable guardrails 9-2 remain parallel. Specifically, the adjustable guardrail 9-2 has a sliding guide block 9-3 at its front end. The adjustable guardrail 9-2 is installed at the bottom of the sliding plate 14. The sliding plate 14 has guide rails 15 on both sides, and sliders 16 are fixed to the outer sides of the guide rails 15 on both sides. The sliders 16 are set on the hanger 12, and a sliding channel is formed between the sliders 16 on both sides. A rack 17 is fixed to the top of the sliding plate 14. The rack 17 meshes with a gear 18. The gear 18 is connected to a rotating shaft 19. The rotating shaft 19 is rotatably connected to the hanger 12. A handle 20 is provided at one end of the rotating shaft 19. Rotating the rotating shaft 19 by the handle 20 can drive the gear 18 to rotate, which in turn drives the rack 17 to rotate, driving the sliding plate 14 to slide, and thus causing the adjustable guardrail 9-2 below to slide, completing the spacing adjustment.

[0045] The small group stop 6 includes a first fixed stop 6-1 and a first quick-shift stop 6-2. The first quick-shift stop 6-2 is disposed on the side of the first fixed stop 6-1, and the first quick-shift stop 6-2 and the first fixed stop 6-1 are detachably connected.

[0046] The first fixed stop 6-1 is provided with a communicating first slot 6-3 and a first slot 6-4. The side of the first quick-change stop 6-2 is provided with a T-shaped snap-fit ​​member 6-5. The snap-fit ​​member 6-5 can be inserted into the first slot 6-3 and pushed into the first slot 6-4 to snap and fix it in place. The first fixed stop 6-1 is also provided with a positioning hole. The side of the first quick-change stop 6-2 is provided with a spring positioning bead 6-6. When the snap-fit ​​member 6-5 is inserted into the first slot 6-3 and pushed into the first slot 6-4, the spring positioning bead 6-6 enters the positioning hole and locks in place. By replacing the first quick-change stop 6-2 with different specifications, the width of the small group channel can be adjusted to accommodate products of different diameters.

[0047] The large-batch stop 7 and the chain plate surface of the large-batch conveyor mechanism 4 are detachably connected. The bottom surface of the large-batch stop 7 is provided with a T-shaped locking block 7-1, and the chain plate surface of the large-batch conveyor mechanism 4 is provided with a communicating second slot 7-2 and a second slot. The T-shaped locking block 7-1 can be inserted into the second slot 7-2 and pushed into the second slot for locking and fixing. The chain plate surface of the large-batch conveyor mechanism 4 is also provided with a positioning pin hole, and the large-batch stop 7 is provided with a spring pin 7-3. After the T-shaped locking block 7-1 is inserted into the second slot 7-2 and pushed into the second slot, the spring pin 7-3 can be inserted into the positioning pin hole for positioning and locking. The large-batch stop 7 is available in different specifications; by replacing the large-batch stop 7, the width of the large-batch channel can be adjusted to accommodate products of different diameters.

[0048] The forming conveying mechanism 5 includes two symmetrically arranged frames 5-1, the distance between the two frames 5-1 is adjustable, and each frame 5-1 is provided with a first conveying chain 5-2 and a second conveying chain 5-3. The packaging box positioning mechanism includes a first positioning block 5-4 and a second positioning block 5-5. Multiple first positioning blocks 5-4 are installed at equal intervals on the two first conveying chains 5-2, and the first positioning blocks 5-4 on the two first conveying chains 5-2 are symmetrically arranged. The second positioning blocks 5-5 are installed at equal intervals on the second conveying chains 5-3, and the second positioning blocks 5-5 on the two second conveying chains 5-3 are symmetrically arranged. A positioning notch is formed between the first positioning blocks 5-4 and the second positioning blocks 5-5 on the same side. The packaging box 10 is placed in the two positioning notches, and the opening of the packaging box 10 is directly opposite the positioning notch. Both the first conveyor chain 5-2 and the second conveyor chain 5-3 have connecting plates fixed to their sides. Mounting blocks are installed on the connecting plates, and slots are provided on the mounting blocks. A first positioning block 5-4 or a second positioning block 5-5 is inserted into the slots. The distance between the first positioning block 5-4 and the second positioning block 5-5 can be adjusted by rotating the first conveyor chain 5-2 and the second conveyor chain 5-3 to accommodate different packaging box widths. The distance between the two frames 5-1 can be adjusted to accommodate different packaging box lengths.

[0049] This invention adopts a side-entry packaging box method, which is more compact, faster, and more efficient than the existing sequential packaging method of bottle separation, bottle pushing, and bag entry. The spacing of the second guide mechanism 9 is adjustable, and the width of the corresponding small group channel, large group channel, and positioning notch can be adjusted by changing the blocks, realizing the packaging of products with different diameters. Moreover, the block replacement method is simple, the changeover time is short, and the labor time cost is reduced.
