Description

Technical Field

[0001] The utility model relates to the field of packaging machines, in particular to a packaging machine and a collecting and conveying mechanism thereof. Background Art

[0002] As people's living standards continue to improve, producers are constantly developing various instant drinks to meet people's needs. Often, in a material package, multiple solid materials need to be mixed in a specific proportion to obtain a mixed solid material for quantitative filling in order to produce the required material packaging containing multiple solid materials.

[0003] However, the prior art generally uses multiple hoppers to store different solid materials, and quantitatively discharge different materials separately, and then mix, package, weigh, and send them out. In addition, the entire processing process adopts intermittent processing, that is, the bag-making mechanism moves intermittently, each time it sends a top-opening packaging bag to the filling station, stops and waits for the filling step to be completed, and then moves again to send the filled packaging bag away, seal it, and send a new packaging bag to the filling station. Each movement and stop is a processing cycle. However, the applicant found that as the amount of materials increases, in order to ensure the ratio of each material, each material needs to be measured separately (usually using an electronic scale), and then the materials are mixed and then filled. As a result, the discharge step usually consumes the most time among all the steps, which means that other steps must wait for the discharge step, making it difficult to shorten a single processing cycle and improve work efficiency.
