There is no dust on the surface. , If there is any deviation in the placement, it needs to be adjusted immediately, and if there is dust, it needs to be cleaned up. Regularly check whether the screws of some parts that are often displaced and mechanically moved are loose, and tighten them if necessary.

If there are any missing screws or nuts, they need to be replaced in time. Parts that are often displaced need to be checked regularly and lubricated. Before each operation of the sachet packing machine, the maintenance of the automatic sachet packing machine needs to check whether there are sundries or foreign objects in the conveyor rail which need to be removed in time.

If there are dust deposits, use compressed air to remove the dust.

sachet packing machine complete useful packaging. Packaging can be based on the requirements of the packaged items to obtain packaging with consistent specifications, but manual packaging cannot be guaranteed.


It can replace manual packaging. Such as skin packaging, isobaric filling, vacuum packaging, inflatable packaging, and another packaging.


Reduce the rest intensity and change the rest conditions. The rest intensity of manual packaging is larger. Manual packaging of bulky and heavy products consumes sales and is not safe.


It is beneficial for workers to rest and protect the health of certain products that are seriously affected by hand-packing.


The human body has a strong immune system and needs to take care of and regulate its self-correcting mechanism in normal times. More careful attention to the staff is required for the sachet packing machine to work properly and maintain good function.

So what is a machine? It’s not just a combination of steel; it’s a child needing care. The machine’s life depends not only on the quality of the machine but also on the acquired protection.


Cleaning, fastening, smoothing, conditioning and anti-corrosion are the key points of packaging machine protection. In the daily production process, machine protection personnel should strictly follow the protection manual and protection procedures of the machine packaging equipment to carry out various protection work, reduce the wear rate of parts, eliminate hidden dangers, and prolong the machine’s service life. Packing Machine.


The protection is divided into daily protection, regular protection (including first-level protection, second-level protection and third-level protection), and special protection (including seasonal protection and outage protection).



Routine protection focuses on cleaning, smoothing, tightening and testing and requires routine protection during and after machine operation.


The primary protection is based on conventional protection; the first job content is smoothing, tightening and viewing the relevant parts and cleaning.


Secondary protection focuses on viewing and adjustment. See Engine, Clutch, Transmission, Transmission Components, Steering and Brake Components.


The third level of protection is mainly to detect, adjust, eliminate hidden dangers, and balance the wear degree of each component. Diagnose and view parts that may affect the function of the equipment and parts with symptoms of failure, and then perform necessary replacements, adjustments and troubleshooting.


It is necessary to add lubricating oil to the mechanical parts after the equipment normally works for about three months to ensure that the sachet packing machine can run freely, reducing the loss caused by friction and prolonging the service life of the equipment.

Before using the automatic bag-feeding vacuum packaging machine, the equipment needs to be tested to ensure that the equipment’s power supply, switch, electrical system, and operating system can work normally. Because of the control part of the bag-feeding vacuum packaging machine, The PLC programmable system is adopted, so the detection function takes only a few minutes. It will not affect the daily production capacity of the working product.

Cleaning work to meet the food hygiene standards, the equipment should be cleaned every day to ensure the cleanliness of the sachet packing machine. Due to the food packaging may have highly corrosive ingredients such as acid, alkali, and salt in the product. , Timely cleaning work can not only improve the corrosion resistance of the equipment but also increase the service life of the equipment.

The “heart” part of the sachet packing machine is also a vacuum pump. When using the equipment, ensure the vacuum pump oil is at 2/3 or 3/4 of the oil window. Too much oil will cause oil injection events. Occurs, polluting the packaging, and too little oil will reduce the vacuum pump’s service life and damage the pump.

Always check whether there are sundries on the isolation cloth of the heating strip and whether it is flat to ensure the sealing quality; once the equipment is installed and debugged, do not move the equipment frequently, and communicate with the technicians when moving the equipment to ensure that the equipment is in good condition.



What is the main working principle of the sachet packing machine?

  1. Molding

The base film needs to be heated before forming. To improve productivity and realize rapid prototyping, there is a preheating zone so that the bottom film has a certain temperature before forming. The heating temperature varies depending on the thickness and material of the base film.

  1. Heat sealing

The upper film covers the bottom film of the tray filled with the material as it enters the heat sealing zone.

The heat-sealing area is provided with a heat-sealing template driven by a cylinder, a heating tube is arranged on the heat-sealing template, and a temperature control element control the heating temperature of the heating tube.

The top and tray bottom films are heat-pressed and sealed by a heat-sealing template. Users can install vacuum and inflatable devices in the heat-sealing area according to their needs to realize inflatable vacuum packaging.

  1. Slitting

After heat sealing, neatly aligned packs are formed, but these packs are joined together, and they must go into the cutting area to be cut crosswise and lengthwise to obtain individual finished packs.

  1. Thin-film traction system

The film pulling system mainly includes a chain clip conveying device, film guiding device and so on.

The longitudinal sides of the sachet packing machine are respectively equipped with a long chain, and each chain pitch is equipped with elastic clips. The transmission of the bottom membrane depends on the clamping and traction of the chain clips on both sides.

The whole process of the bottom film, from importing to packaging, cutting, and outputting, is clamped with clips. Due to the large number of clips distributed longitudinally on the chain, the bottom film can be transported horizontally. The base film remains flat even during molding and filling.

When the bottom of the pin of the clip is subjected to an upward force, the clip rises and compresses the spring through the fastener. At this point, there is a gap between the rounded end of the clip and the top surface of the deck, enough to insert the edge of the film. When the force on the bottom of the pin of the clip is removed, the clip is reset by the spring force to clamp the membrane.
