1. Introduction
In daily life, we encounter various liquid viscous products, such as shampoo packets, instant noodle sauce packets, KFC ketchup packets, and various seasoning packets used in cooking. These items greatly facilitate people's lives. These highly fluid viscous substances are processed into small bags using an oil-packaging machine.
2. Equipment Introduction
Oil packaging machines are specialized equipment used for packaging viscous items with a certain degree of fluidity, such as seasoning packets in instant noodles, jams, ketchup, emulsions, and sauces.
The equipment can automatically measure, feed, make bags, seal, mark, and tear the packaging, and is equipped with automatic material level control, anti-drip and anti-stripping devices.
The equipment operates continuously, without stopping during sealing and bag cutting, thus achieving high packaging efficiency and making it a commonly used piece of equipment in automated production.
3. Process Principle
The oil packaging machine automatically completes processes such as quantitative feeding of seasoning cylinders, bag making, sealing, cutting, and finished product discharge (optional accessories include punching, corner cutting, coding, and inflation).
Longitudinal sealing shaft: Forms the packaging film and achieves longitudinal sealing;
Horizontal sealing shaft: transverse heat sealing;
Cold-sealed shaft: Cold-sealed after heat sealing to prevent liquid dripping and stringing;
Cutting shaft: Cuts the seal in the middle to output the finished product.

4. Features of the scheme
Electronic cam control scheme
The three axes of horizontal sealing, cold sealing, and cutting are formed into a cam.
The configuration creates complex reciprocating motions, simulating the cam's operating pattern through a digital system. Combined with various compensation methods, this achieves precise control.
One-to-four servo solution
A single servo motor can drive four motors, offering higher precision and stability, more complex motion modes, smaller footprint, and lower cost compared to traditional one-to-one control methods.
Lost label detection algorithm
The equipment has the ability to self-adjust and can plan the number of lost bids. Through calculation, it can calculate compensation based on the theoretical position when a bid is lost, thereby improving its accuracy and efficiency.
5. Advantages of the solution
01#
Easy to operate
One-click start during startup, one-click reset in case of failure.
02#
High precision
Cutting accuracy is ±1mm, and real-time compensation is achieved through an improved compensation calculation method. The tear position is precise; a built-in algorithm ensures the tear position remains consistent regardless of bag length or speed.
03#
Electronic Cam
The electronic cam control scheme is adopted, which is stable and efficient.
04#
1-to-4 servo control solution
Control can be completed with a single server, reducing costs.
Performance indicators
Bag length range: 60~160mm; Production speed: 130 pcs/min for bag length 75mm.
