The temperature-time adjustment is too high and too long


Overhaul or replacement (if the heat sealing delay is too long, the power supply should be cut off in time).

What are the classifications of seed packing machines?

There are many different types of packaging machines, and different types are also divided into many types according to different classification methods. Generally, the classification is not too complicated under normal circumstances. Generally, they are mainly divided into two categories. The two types will have different usage and operations, fully automatic and semi-automatic.


The fully automatic method of use is generally relatively simple because the labor force is very small; the machine’s automatic bag feeding, automatic measurement, automatic bagging, automatic bag transfer, automatic bag sewing, and this series of operations are not required. Manpower these can be done independently by the automatic packaging machine. It is more convenient to operate, while the semi-automatic packaging machine is less convenient than the automatic one. Still, it will also perform automatic measurement and automatic bagging. Still, the bag needs to be added manually in the process. It also needs to manually move the bag, manually hold the pocket for packaging, etc., which is a little more troublesome than fully automatic.


There are other classification types of packaging machines, which are divided into three categories according to the different physical properties of materials. Gravity feeding packaging machine: granular materials with good flowability and small moisture content. Auger feeding: generally used for metering and packaging of powder. Belt feeding: generally used for a block or granular belt and has a wide range of applications. If it is divided according to packaging specifications: small packaging, conventional packaging, ton packaging, etc.

What are the application areas of the seed packing machine?

Technology has given packaging a new look. Among them, the bag-type packaging machine realizes packaging automation for the pharmaceutical, food, chemical and other enterprises. The operator only needs to place hundreds of bags in the bag-taking part of the equipment at one time, and the mechanical grip of the equipment will automatically take out the bags and arrange them. Date printing, bag opening, signal metering to the metering device, blanking, sealing, and output.

In addition, the bag-feeding packaging machine can also be used for multiple purposes.

What are the packaging conditions for the seed packing machine?

  1. The thickness of the bag should be one to one, maintain a certain hardness, and the packaging bag should not have any abnormality such as twists or turns.
  1. The material in the packaging bag should be less than 20MM below the mechanical gripping bag to ensure the sealing quality
What are the working procedures for the seed packing machine?

To bag – coding – opening bag – filling/tapping – reserved station – reserved station – heat sealing – cooling/output.

What are the common sealing methods of seed packing machines?

There are roughly the following types of packaging and sealing methods:

  1. Back-sealing packaging method (using pillow packaging machine or vertical packaging machine)
  1. Four-side sealing packaging method (using the vertical machine, bagging machine or sealing machine)
  1. Three-side sealing packaging method (vertical packaging machine is used)
  1. Blister packaging method (using a blister packaging machine, the packaging effect is like a toothbrush you have seen)
  1. Triangular bag packaging method (using vertical packaging machine)
  1. Heat shrink packaging method (using heat shrink packaging machine + heat shrink furnace)

Notes on daily protection of seed packing machine:

The box’s upper part of the box is equipped with an oil gauge, which should be filled with oil once before starting, and can be increased in the middle according to the temperature rise of each bearing and the working conditions.

The oil of the seed packing machine needs to be stored in the worm gearbox for a long time. The oil level is so high that the worm gear completely penetrates the oil. If it is used frequently, the oil should be replaced regularly. An oil plug is at the bottom of the worm gearbox for oil drainage.

When refueling the machine, do not let the oil spill out of the cup, let alone flow on the ground and around the machine. Because the oil easily contaminates materials and affects product quality.

Check the parts of the seed packing machine regularly, once a month, check whether the worm gear, worm, bolt, bearing and other moving parts on the lubricating block are sensitive to rolling and wear, and correct errors in time; do not use it logically.

The equipment should be used in a dry and clean room and not in places where the air contains acids and other corrosive gases.

When the seed packing machine is in use or stopped, the drum should be taken out for cleaning, brushed off the remaining powder in the barrel, and then installed correctly to prepare for the next use.

If the downtime is long, the entire body of the seed packing machine needs to be scrubbed clean, and the lubricating surface of the machine parts is coated with anti-rust oil and covered with a cloth.

The fully automatic seed packing machine is equipped with electrical control components, do not directly flush the body otherwise the electrical control components will be damaged, and there will be an electrical shock;

Meet the power and air source specified by the equipment;

Before removing the equipment, be sure to turn off the air source and power supply;

Install a grounded power socket for the packaging machine so that the machine is well-grounded and avoids electric shock.

Some circuits in the electrical controller still have voltage after the power switch is turned off, so be sure to unplug the power cord when troubleshooting control circuits.

​The seed packing machine adopts a PLC control system and a pneumatic system with self-checking faults. We focus on relevant matters to ensure the efficiency and safety of production.

What are the benefits of using a seed packing machine for a business?

Green environmental protection is deeply rooted in people’s hearts. Equipment in all walks of life has also begun to be transformed into green environmental protection machinery, taking the green route. The production process of the seed packing machine is stable, low noise, convenient, high production efficiency and fast production speed. Adding the green concept makes the seed packing machine simple but not simple. The development trend of packaging machines is to help companies save costs and reduce waste.

The green packaging machine covers many levels. First, high production efficiency is the most direct manifestation, and production efficiency is the basis for the survival of enterprises. Therefore, improving the production efficiency of packaging machinery is crucial for enterprises. Secondly, the production process must be low noise and environmentally friendly, which is also the basic requirement of modern production machinery. In the end, it is the control of production costs and trying to get the maximum production value with the least capital investment.

Of course, we can’t make this the ultimate goal, but we should put our vision in the longer term and make the advantages more obvious. Green and environmentally friendly, bringing seed packing machines into a new era of development.

The rise of the packaging industry has given packaging machinery a broad space for development as the main packaging equipment. With the introduction of the concept of green environmental protection, packaging machinery should also adapt to this trend and transition to green packaging machinery.

What impact has the seed packing machine brought to the food processing industry?

Nowadays, many people love to buy food online. In addition to fresh food, some cooked food products are also very popular among consumers. Foodies are always unable to resist the temptation of delicious food. This is widely used in a piece of technical equipment – vacuum packaging. It can be said that without the application of vacuum packaging technology, many foods cannot be operated and sold from offline to online, and the market value of seed packing machines is irreplaceably important.


In recent years, China’s food packaging machinery industry has gradually developed into one of the fastest-growing and most dynamic pillar industries in China’s national economy. With the development of various food industries, people’s requirements for food safety have also increased, which has prompted the development of the vacuum packaging industry.

In the market, many products need to be vacuum-preserved, especially food, which needs to use the vacuum to slow down the decay of the product and retain the moisture of the product. The bag-type packaging machine was born to meet the demand, which is why it can quickly occupy the market after it was launched.

It should be said that the seed packing machine is relatively young equipment. After being tempered by the market, it has also made great progress. Higher vacuum, the ability to fill with other gases, and the deepening of automation are undoubtedly not feedback on consumer demand. As Chinese companies also diversify the types of vacuum packaging equipment, more and more equipment appears in front of consumers to meet their different needs of consumers.

Bring the gospel to the seed packing machine for the food industry.

Vacuum packaging can be seen everywhere in our lives; especially food packaging is often used. Vacuum packaging technology is a packaging technology with relatively high technical content, which requires the use of specially designed bag-feeding packaging machines for packaging. Nowadays, vacuum packaging is the most common packaging method for food packaging, which is also the gospel brought by technological progress to the food industry.

At the same time, the food industry is undoubtedly a very strong economic part of the world with high investment, so the food packaging industry is a fairly large market. This industry is also the largest buyer of seed packing machinery, with a share of nearly 70%. Therefore, the development of the seed packing machine industry must take a long-term development path.

Vacuum packaging is very simple to understand. It is to use a vacuum pump to extract the air in the packaging to achieve an oxygen-free environment, which can fundamentally prevent the rot and deterioration of the product, thereby achieving long-term preservation of the product. This packaging method is not only easy to operate but also relatively inexpensive, so it quickly occupied the market.

After years of development, the seed packing machine has become more and more perfect. The improvement of the new vacuum pump technology and the whole-process control of the numerical control technology make the vacuum packaging more reliable and reliable. Many Chinese companies focusing on seed packing machinery are also working hard on seed packing machines. They have launched more and more vacuum packaging equipment to meet the various needs of enterprises and markets.

In today’s developing society, vacuum packaging technology will inevitably go further. Although it has become the trend of food packaging technology, vacuum packaging technology also needs to accelerate its development. The progress of science and technology is the primary productive force, and only through continuous improvement can we always walk at the forefront of the times.

For a long time, the development trend has been rising steadily. Currently, the common bag-feeding packaging machines on the market are semi-automatic vacuum equipment. Just press the vacuum cover to complete the vacuuming, sealing, printing, cooling and exhausting process. To establish a new packaging machinery system with diversification, generalization and multi-function integration, we must first focus on solving the big problems of combination and mechatronics, which is undoubtedly an important development direction in the future.

With the development and application of high-efficiency and multi-functional bag-feeding packaging machines and packaging materials with excellent barrier properties, as well as the combination of vacuum packaging and physical and chemical methods such as inflation, radiation, freezing, oxygen absorbers, and ethylene absorbers, the It will achieve better storage and preservation effect.
