Description

Technical Field

[0001] This invention relates to the field of conveying device technology, and in particular to a conveying mechanism for a birch sap bag-breaking and collection device. Background Technology

[0002] When birch sap is collected from the tree, bagged, and sent to the factory for processing, the outer bags often contain a significant amount of dirt, leaves, and other impurities. If these impurities are not cleaned, they will contaminate the birch sap and affect product quality. Furthermore, current technologies primarily rely on manual bag-breaking for sap collection, which is inefficient and cannot guarantee cleanliness. Therefore, there is an urgent need for a fully automated birch sap bag-breaking and collection device that ensures cleanliness and efficiency, enabling high-purity, large-scale birch sap recycling. This device would clean and dry the collection bags before breaking them to collect the sap. The inventor's objective is to design a conveyor mechanism that can transfer the collection bags between different modules. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the main objective of this invention is to provide a conveying mechanism for a birch sap bag-breaking and collection device that can easily attach collection bags, is stable and reliable, and can automatically drop the bags.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a conveying mechanism for a birch sap bag-breaking and collection device, comprising two parallel annular tracks fixed by a hoisting bracket, each annular track having an active drive sprocket driven by a drive motor at one end and a driven sprocket at the other end, wherein a circular chain connects the active drive sprocket and the driven sprocket, and the two circular chains in the two annular tracks run in opposite directions, comprising a collection bag storing birch sap, wherein the collection bag has a protruding circular cover, the circular cover being able to overlap between the two circular chains.

[0005] Preferably, the two parallel annular tracks each have a flared structure at their tail ends, and the collection bag falls through the flared structure.

[0006] Preferably, a guide plate is provided at the entrance of each circular track.

[0007] Preferably, several hoisting brackets are respectively set on the two circular tracks, and two adjacent hoisting brackets set side by side are fixedly connected by tie rods.

[0008] Compared with existing technologies, this invention has the following advantages: it fully automates the process, replacing inefficient manual operations; it avoids contamination of the bag body by non-contact point-contact transmission through the cap, ensuring the cleanliness of birch sap recycling; structurally, it eliminates complex clamping components, relying solely on the flared structure at the end of the track to increase the chain spacing and achieve gravity bag dropping; combined with the precise guidance of the inlet guide plate and the lifting bracket system reinforced by the tie rod, it ensures stable and reliable operation, not only reducing the failure rate and maintenance costs, but also flexibly adapting to the production line layout of processes such as washing, drying, and bag breaking; and it supports the automation needs of large-scale high-purity birch sap recycling equipment with minimal standardized sprocket and chain components.

[0011] The invention will now be further described with reference to the accompanying drawings.

[0012] like Figure 1 As shown, a conveying mechanism for a birch sap bag-breaking and collection device includes two parallel annular tracks 1 fixed by a hoisting bracket 2. Each annular track 1 has an active drive sprocket 10 driven by a drive motor 3 at one end and a driven sprocket at the other end. A circular chain 4 connects the active drive sprocket 10 and the driven sprocket. The two circular chains 4 in the two annular tracks 1 run in opposite directions. The device includes a collection bag 5 containing birch sap. The collection bag 5 has a protruding circular cover 6, which can overlap between the two circular chains 4.

[0013] Preferably, the two parallel annular tracks 1 are each provided with a flared structure 7 at their tail ends, and the collection bag 5 falls at the flared structure 7.

[0014] Preferably, a guide plate 8 is provided at the entrance of each circular track 1.

[0015] Preferably, each of the two annular tracks 1 is provided with a number of hoisting brackets 2, and two adjacent hoisting brackets 2 arranged side by side are fixedly connected by tie rods 9.

[0016] This solution presents a conveying mechanism for a birch sap bag-breaking and collection device. The core of the mechanism consists of two parallel circular tracks 1. Each circular track 1 is tensioned by a drive sprocket 10 (motor-driven) and a driven sprocket, holding a circular chain 4 in reverse. The two circular chains operate in opposite directions. Circular chains are used because they offer better rigidity than other conveying structures, and the collection bag 5, when filled with birch sap, is quite heavy, making it difficult for other conveying structures to support it. When the circular cap 6 at the top of the collection bag 5 overlaps between the two opposing circular chains, the cap is clamped between them, propelling the collection bag 5 forward stably along the track direction. This design eliminates the need for traditional mechanical grippers, relying solely on friction for transmission. A flared structure 7 is provided at the end of the circular track 1, gradually increasing the distance between the two circular chains. When the collection bag 5 reaches this area, the cap loses chain support and falls automatically under gravity, achieving unloading without power. This structure avoids complex sensors or pushing devices, simplifying the process. A guide plate 8 is installed at the track entrance to ensure that the cover of the collection bag 5 is accurately embedded in the chain gap, reducing jamming. Multiple lifting brackets 2 fix the annular track 1 and are laterally connected to adjacent brackets via tie rods 9 to form a rigid frame. This structure resists vibration during chain operation, prevents track deformation, and ensures stability for long-distance transmission.

[0017] The advantages of this solution are that it fully automates the process, replacing inefficient manual operations. The contactless point-contact transmission through the cap avoids contamination from adhering substances on the bag, ensuring the cleanliness of birch sap recycling. Structurally, it eliminates complex clamping components, relying solely on the flared structure 7 at the end of the track to increase the chain spacing and achieve gravity bag dropping. Combined with the precise guidance of the inlet guide plate 8 and the lifting bracket 2 system reinforced by the pull rod 9, it ensures stable and reliable operation. This not only reduces the failure rate and maintenance costs but also allows for flexible adaptation to the production line layout of processes such as washing, drying, and bag breaking. The simplified sprocket and chain standardized components support the automation needs of large-scale high-purity birch sap recycling equipment.
