What is the Double-Terminal Knotting Wrapping Machine
The double-terminal knotting wrapping machine is an automated equipment specifically designed for packaging long and small-shaped products such as candies, chocolates, ice cream, and small daily-use items. It wraps the product with a roll of packaging paper and then tightens and seals the two ends, which is the common double-terminal knot packaging we see.
Depending on the operating mode, it is mainly divided into two types in the industry:
Intermittent Double-Terminal Knotting Wrapping Machine (step-by-step operation, stable, accurate, and high quality)
Continuous Double-Terminal Knotting Wrapping Machine (continuously running, fast, high output, suitable for large quantities)
Intermittent Double-Terminal Knotting Wrapping Machine (Step by Step, Perfectly Wrapped)
1. Working Principle: Stop, then wrap. Precise and without disorder.
Its core is a process disc that intermittently rotates, like a clock wheel. It stops after turning by an angle, and each stop completes one packaging action:
Adding sugar and paper: Put the candies and packaging paper together onto the clamp. The paper automatically wraps into an U-shape, covering the lower part of the candies.
Edge folding wrapping: Fold the paper up and down to make it flat, and wrap the candies all around.
Double-ended knotting: Both ends are twisted and held by the hands. Rotate while moving towards the center to tighten and seal the paper.
Pushing out the finished product: The clamp opens, and the finished product is pushed out, completing one package.
The entire process has stops and movements, and is completed step by step, so the packaging is very neat and won't be crooked.
2. Main Structure (Simple to Understand)
Sugar sorting and feeding: Vibrating hopper + rotating disc + brush, arranging the candies neatly, without overlapping or jamming.
Paper feeding mechanism: The paper reel automatically pulls out, and can simultaneously feed two layers of paper (liner + logo paper), without deviation or paper shortage.
Paper pulling and cutting: Pull the paper to a fixed length, cut it smoothly and evenly with one stroke, with uniform length.
Wrapping mechanism: A rotating disc with a clamp, combined with the folding paper board, wraps the paper tightly around the product.
Knotting mechanism: Two sets of knotting hands, clamping → rotating → axial movement, twisted tightly, not loose, and without paper shortage.
3. Advantages
The packaging is very neat and the knotting is beautiful, with stable quality.
It is convenient to change product specifications, suitable for multiple varieties and small batches.
It can stop feeding paper without candies, avoiding waste of packaging materials.
The continuous double-ended knot wrapping machine adopts continuous dynamic operation, without intermittent start-stop or separate start-stop of each process, and runs synchronously throughout the entire process. It has high production capacity, fast speed, and stable operation; the equipment has a compact structure, simple transmission, and few moving parts, which can reduce wear and maintenance costs, and has stronger stability; relying on the forming and dynamic knotting process, the packaging is neat and compact, the product quality is consistent, the automation level is high, it is suitable for single-product industrialization, large-scale, and high-speed continuous production, and can effectively improve the efficiency of the packaging line and the quality of product packaging.
| Project | Intermittent | Continuous type |
| Operating mode | Turn around for a moment, then stop for a while. | Continuous movement throughout the entire process |
| Packaging speed | Medium, stable, and reliable | Quick! High output! |
| Packaging effect | Very neat, beautiful, and accurate in alignment. | It's also fine, but the chain will deviate after wearing out. |
| Ease of product replacement | Very convenient, suitable for multiple varieties | Suitable for long-term packaging of the same product |
| Paper-saving situation | No sugar, no paper will be given. No waste. | Lack of sugar will also send out the paper, which is a bit wasteful. |
| Appropriate scenario | A wide variety of products, small batch sizes, and high-end candies | Single product, large batch, high-speed production line |
FAQ
Q: What is the double-ended knotting wrapping machine? What products is it suitable for?
A: This is an automated knotting and sealing packaging equipment. It wraps the product with a roll of paper and tightens the ends for sealing. It is mainly suitable for packaging operations of long and small-shaped products such as candies, chocolates, ice cream, and small items of daily use.
Q: What are the core differences and applicable scenarios between intermittent and continuous double-ended knotting wrapping machines?
A: The intermittent type adopts step-by-step start and stop operations, with high packaging accuracy, flexible model changes, and cost savings on consumables. It is suitable for multi-variety and small-batch production; the continuous type operates without interruption and is dynamic, with high speed, large production capacity, and low operation and maintenance costs. It is suitable for single-category, large-batch, and high-speed industrialized mass production.
Q: What is the working principle of the intermittent double-ended knotting wrapping machine?
A: It operates in a step-by-step manner through intermittent rotation processes. It sequentially completes the processes of feeding sugar and paper, U-shaped wrapping, edge folding and sealing, double-ended knotting, and product ejection. The operation is precise, and the packaged products are neatly and orderly.
Q: What are the main advantages of the intermittent wrapping machine?
A: The packaging quality is stable, with regular knotting without flaws; product specifications can be easily changed, and it is flexible for multi-category production; it has the function of not feeding paper without sugar, which can effectively reduce packaging material waste.
Q: What are the core advantages and production value of the continuous double-ended knotting wrapping machine?
A: The equipment structure is simple, with fewer moving parts, low wear, strong stability, and low operation and maintenance costs. It operates synchronously and at high speed, with high production capacity. Relying on the dynamic knotting process, the packaged products are compact and of uniform quality, which can significantly improve the overall efficiency and packaging quality of large-scale production lines.
