Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] See also Figure 1 and Figure 2 , this application provides the following technical solutions:

[0048] A chain conveyor mechanism includes a long conveyor frame 11, which is a supporting structure of the chain conveyor mechanism, and the length direction of the conveyor frame 1 is its conveying direction; a conveyor chain 12 is arranged in the conveyor frame 11, and the conveyor chain 12 is a sprocket chain combination, wherein the chain 121 is arranged in a ring shape in the conveyor frame 11. A conveyor frame group 13 is arranged on the conveyor chain 12, and the conveyor frame group 13 includes a plurality of conveyor frames 131, and one conveyor frame 131 is fixedly arranged on each section of the chain 121.

[0049] Each conveying rack 131 includes a rack connecting portion 1311, which is a rectangular block. The conveying rack 131 is fixedly connected to the conveying chain 12 through the rack connecting portion 1311. A plurality of rack partitions 1312 are arranged in parallel on the rack connecting portion 1311, and a placement slot is formed between the rack partitions 1312. The placement slot is used to place long bagged items to be loaded on a plate. The height of the rack partition 1312 is lower than the product thereon. For example, when the bagged oral liquid product conveyed by the mechanism of this scheme is placed in the placement slot, its length direction is parallel to the length direction of the placement slot, and the product is in a horizontal state, and its upper part is exposed on the upper side of the conveying rack 131. As the chain 121 of the conveyor chain 12 rotates, the conveyor rack 131 on it is transported to the unloading position together with the product. The conveyor mechanism of this scheme needs to be used in combination with other unloading devices. A horizontal push plate structure can be partially set above the conveyor chain 121 to push over the conveyor rack 131 at one time, and push the exposed product part on the conveyor rack 131 to push the product out of this conveyor mechanism. Figure 2 As shown, the conveying frame 131 is a rectangular structure, and its length direction is perpendicular to the length direction of the conveying chain 121 . The discharging direction of the conveying mechanism is parallel to the length direction of the conveying frame 131 .

[0050] Based on the above implementation scheme, see Figure 2 The conveyor rack 131 of this scheme adopts two different structural forms, both of which are a combination of a frame connecting part 1311 and a frame partition 1312, and the distribution structure of the frame partition 1312 of the two is different. One is a four-plate structure with four frame partitions 1312 arranged on the frame connecting part 1311, and the other is a three-plate structure with three frame partitions 1312 arranged.

The conveyor rack 131 of the three-plate structure is a group with the conveyor rack of the four-plate structure, and this group is provided with 7 placement positions for placing products. The frame partitions 1312 on the three-plate structure have spacings on both sides of the frame connecting part 1311, one of which is equivalent to a complete placement slot, and the other spacing is combined with the adjacent four-plate structure conveyor rack 131 to form a placement slot.

[0051] This structural form of the present invention takes into account the optimal utilization of the corresponding product placement space. In this structure, when the chain 121 rotates to the end, the conveyor frame 131 rotates from the upper side to the lower side following the node position of the chain 121 where it is located. The conveyor frame 131 of this structure of the present invention is more likely to cause the product thereon to fall off.

[0052] On the basis of the above embodiment, the conveyor frame 11 includes a long rectangular conveyor chain bin 111, the conveyor chain bin 111 is hollow inside and open at the top, and the conveyor chain 12 is arranged in the upper area of ​​the conveyor chain bin 111. A conveyor support 112 is arranged at the lower side of the conveyor chain bin 111, and the conveyor support 112 is used to support the conveyor chain bin 111; the conveyor support 112 includes a plurality of support rods, such as Figure 1 As shown, the lower part of the conveying bracket 112 is provided with rollers and a support block with adjustable height.
