Inventions Patents

Many people may not know that it is very easy to apply for design patents in China, followed by utility model patents. The most difficult one is invention patents. Invention patents require substantial innovation and will be subject to strict review(Only about 1/4 of our inventions patents application was approved). Many machinery companies may claim to have a lot of patents, but they may only have design patents that have no technical content in the industry.


Transmission Part

Our transmission has a T-shape layout, which is more concise than the concave-shape layout used by some machines. This kind of transmission is more efficient and more stable.

In order to ensure the stable operation of the machine at high speed, our cam indexers are specially customized. They have particularly large torque, sealed lubrication, and very high accuracy. The entire transmission part has undergone a destructive test of 180 times per minute for 3 months.

Processes: raw materials(special carbon steel) → rough finish → soldering → temper → CNC finish machining → assembly

Frame processes1
Frame processes2
Frame processes3

The frame adopts the integrated processing method of welding and milling to ensure that the frame is not easily deformed. It directly determines the stability and precision of the equipment. The frame plate is twice the thickness of the ordinary frame, and the chassis thickness is 30mm, making the weight of the machine up to 3.5 tons(The heavier the frame, the more stable the machine). These all directly determine the stability and precision of the equipment.



Our machine adopts a circulating oil supply system, which directly injects into the inside of each bearing and the surface of gears and cams to form an oil film to eliminate the heat of high-speed operation and ensure that the cam is not broken for life.

circulating oil supply system


Using curved indexing cam: The structure is medium-loaded, high-speed, and high-precision indexing. The box body is closed, the whole is soaked in oil, it is not easy to wear and no impurities enter. As mentioned before, our cam will not be damaged, so we can provide a lifetime warranty.

Cam processing technology: Blank → Fine Turning → Rough Milling → Drilling and Tapping → Quenching → Sandblasting (surface treatment) → Internal Grinding → Fine Milling → Coding → Wire Cutting → Blackening


Vacuum Chamber

The Vacuum Chamber is made of aviation aluminum directly engraved and milled in the computer processing center to ensure airtightness and durability.
The specific process is: original blank → milling → oxidation

Given Bag Turntable

The original high-speed bag-feeding turntable adopts a 10-station design. More stations provide more industrial packaging process requirements under high-speed conditions. The strengthened turntable seat and turntable shaft sleeve are made of 304 stainless steel, which has great anti-corrosion performance improve.

The center shaft is integrally processed with imported special steel (post-processing with 45 steel welded flanges for ordinary machines).

Whether it is bag loading, bag opening, or bag support, it is designed and manufactured at a rate of 120 times per minute. The bag support does not need any slot and roller, and the driving only relies on the cam, which is still stable and does not shake at a speed of 100 times per minute.

Vacuum Turntable

The vacuum turntable bearing seat, bearing and turntable are all redesigned and manufactured, and the rigidity and strength are more than twice that of the others machine.

Cleaning and Maintenance

Above the frame table, the part that may be in direct contact with the package is made of 316L stainless steel, and the other parts without special process requirements are made of 304 stainless steel, and the surface is brushed or polished. When cleaning, just wipe it with a towel and detergent.

Above the frame table, the transmission bearing adopts stainless steel bearing or igus oil-free bearing. The rolling bearing is equipped with a waterproof oil seal and is equipped with an oil injection hole, which can not only fully maintain the lubrication performance and life of the bearing, but also prevent the corrosion of the bearing.

Above the frame table, all installation holes are treated with waterproof glue to prevent water from entering the frame.

Protective Function

  • Bag warehouse detection —— if the bag warehouse is lack of bags, the machine will automatically alarm and stop.
  • Bag opening detection —— the bag mouth is not opened, the bag does not add materials, and does not enter the next station.
  • Empty bag detection —— when the bag is empty, the bag does not enter the next station.
  • Sealing current detection —— if the current of the sealing heating wire is too large or too small, the machine will automatically alarm and stop.
  • Vacuum detection —— the vacuum degree is lower than the set value, the machine will automatically alarm and stop.
  • Open lid detection —— if the vacuum chamber lid is not opened, the machine will automatically alarm and stop.
  • The PLC system has helpful information, which is more user-friendly.
