3. Core Equipment Configuration

3.1 Finished Bag Sorting & Conveying System

It receives finished sealed bags from the upstream packaging machine, completes automatic sorting, direction adjustment and steady conveying, and delivers bags to the case packing station in order.

· Equipped with guide and positioning mechanism to ensure consistent bag direction

· Stainless steel belt conveyor, food-grade design, easy to clean

· Speed adjustable, matching the production rhythm of upstream equipment

· With buffer function to avoid material accumulation during production

3.2 Automatic Case Packer

It automatically loads sorted dog food bags into corrugated cases, supporting both side-loading and top-loading modes according to product specifications.

· Automatic case forming, bag counting and case loading function

· Compatible with various bag sizes and case dimensions, easy to adjust

· High packing accuracy, avoiding missing or wrong packing

· Stable operation at high speed, suitable for continuous mass production

3.3 Automatic Case Sealing Machine

It completes the sealing of packed cartons with adhesive tape, with neat and firm sealing effect.

· Automatic top and bottom tape sealing, smooth and beautiful sealing

· Suitable for standard carton sizes, tool-free adjustment for different cases

· Durable structure, low maintenance cost, stable performance

· Can be equipped with corner sealing function for heavy load requirements

3.4 Online Inkjet Coding Machine

It prints production date, batch number, shelf life and other information on the surface of sealed cartons, meeting product traceability requirements.

· High-definition inkjet printing, clear and wear-resistant characters

· Supports multi-line text, barcode and QR code printing

· Online synchronous printing, no need to stop production for coding

· Low consumption of consumables, easy to maintain and operate

3.5 Automatic Palletizing Robot

It stacks sealed cartons on pallets automatically according to the preset stacking mode, completing the final packaging process.

· Multi-axis robotic arm, flexible and stable palletizing operation

· Supports various stacking modes and pallet specifications

· High stacking precision, neat and stable palletizing layers

· Can work continuously for 24 hours, greatly reducing manual handling labor

4. Production Workflow

1. 1. Finished sealed dog food bags are conveyed from upstream to the sorting system

2. 2. Bags are sorted, oriented and buffered, then fed into the case packer

3. 3. Automatic case forming and quantitative bag loading into cartons

4. 4. Packed cartons are conveyed to the sealing machine for tape sealing

5. 5. Online inkjet coding prints production information on carton surface

6. 6. Sealed and coded cartons are transferred to the palletizing station

7. 7. Palletizing robot stacks cartons on pallets according to preset mode

8. 8. Full pallets are output for forklift transportation and warehousing

5. Key Advantages

· Fully automatic end-to-end operation: reduces manual intervention by more than 80%, saves labor costs

· Food-grade design: all contact parts adopt 304 stainless steel, meeting pet food production hygiene requirements

· Strong compatibility: supports various bag specifications and carton sizes, fast product changeover

· Stable and reliable: continuous 24-hour production capacity, low failure rate

· Modular design: can be customized and expanded according to actual production needs

· Intelligent monitoring: with fault alarm and production counting function, easy for production management

6. Application Scope

This packaging line is specially designed for bagged dog food production, and is also widely applicable to the end-of-line packaging of other bagged granular products such as cat food, bird food, rice, seeds and feed. It is an ideal choice for medium and large pet food manufacturers and food processing enterprises to improve packaging efficiency.
