[0027] Packaging: Unroll one end of the packaging film roll 203 along the support platform 202 near the conveyor belt 101 to its top, and place both sides on the support plate 204 to fully open it so that the dried bean curd sticks can be conveyed onto it. Then, gradually align and merge the two sides of the packaging film along the guide plate 305 and pass it through the imprinting roller 303 for thermoplastic imprinting, wrapping the dried bean curd sticks inside. The imprinting roller 303 rolls and imprints the plastic film, pushing the dried bean curd sticks towards the second conveyor mechanism 4. The second conveyor mechanism 4 pushes the tubular dried bean curd stick packaging strips towards the packaging film sealing mechanism 5 at a uniform speed. When the infrared detector 503 at the end of plate 403 detects an obstruction, the hydraulic telescopic component 502 does not move. When the section of dried bean curd sticks passes through the infrared detector 503, the signal is connected, and the hydraulic telescopic component 502 controls the heat-sealing plate 1 504 to move downward until it closes with the heat-sealing plate 2 508, heat-sealing the cylindrical plastic film into a bag. At the same time, the toothed cutting plate 1 507 and the toothed cutting plate 2 509 also match and cut the heat-sealed section, forming an independent dried bean curd stick package, which is then pushed by the conveying mechanism 2 4 on the other side to the conveying mechanism 3 6 for the next step of boxing.
