Small-bag Weighing & Big-bag Secondary Packaging Line for Casual Snacks
Fully automatic snack secondary packaging line with 14-head combination weigher. Small bag big bag packaging machine for nuts and puffed food. High precision, leak-proof sealing, and modular design for food processing.
The casual snack secondary packaging line is a fully automated, high-efficiency packaging solution specially designed for small-bag weighing and large-bag repackaging of leisure snacks. Adopting a modular integrated structure, the entire production line consists of a vibratory feeder, bucket elevator, 14-head combination weigher, vertical packaging machine and finished product conveyor, realizing one-stop automatic production from material feeding, precise small-bag weighing, inner bag packaging to secondary large-bag sealing and finished product output.
This full-automatic snack secondary packaging unit stands out with ultra-precise weighing performance, stable continuous operation and zero-defect packaging quality. It is professionally customized for the popular "small bag inner packing + big bag outer secondary packing" production mode in the leisure snack industry. The equipment automatically loads prefabricated small packaged snacks into large outer packaging bags and completes precise sealing and shaping, thoroughly avoiding manual counting errors, loose sealing and low packaging efficiency caused by manual operation. It greatly optimizes the entire packaging process, lowers enterprise operating costs, and supports large-scale, standardized and intelligent mass production for food packaging enterprises.
Working Principle & Operation Logic
The whole packaging line adopts upstream feeding, midstream precise weighing and packaging, downstream conveying and output integrated working mode. First, the vibratory feeder evenly and quantitatively outputs snack materials, and the bucket elevator vertically transports the materials to the 14-head combination weigher. The combination weigher conducts high-precision dynamic weighing and material distribution to meet the fixed weight requirement of single small packages. After that, the vertical packaging machine completes automatic bag making, filling, sealing and cutting of small snack bags. Finally, the sorted and qualified small packaged products are repackaged and sealed into large outer bags, and the finished product conveyor delivers the finished packages to the next production link, realizing fully unmanned automatic cyclic operation of the whole line.
Equipment Composition & Functional Description
Vibratory Feeder: Achieves uniform and stable quantitative material feeding, ensures continuous and orderly material supply for the subsequent weighing process, and avoids material accumulation and blank feeding.
Bucket Elevator: Stably conveys snack materials to the weighing equipment, realizing vertical material transportation, saving factory space, and matching the full-line automatic operation rhythm.
14-head Combination Weigher: Provides high-precision dynamic weighing, with accurate metering for small-bag snack materials, effectively guaranteeing consistent net weight of each small package and meeting industrial packaging precision standards.
Vertical Packaging Machine: Completes automatic forming, sealing and cutting of small bags and secondary sealing of large outer bags, with neat packaging and tight sealing to ensure product packaging quality.
Finished Product Conveyor: Automatically transports the final packaged products, realizing seamless docking with subsequent sorting, stacking and other processes, and improving overall production continuity.
Product Advantages
High Precision Packaging & Stable Weighing
Adopts advanced 14-head intelligent combination weigher, supporting multi-group material combination weighing.
