Technical Innovation of ADB69 Automatic Tons Bag Packaging Machine

This article summarizes the performance, structure and working principle of the ADB69-ton bag packaging machine, as well as existing problems, improvement measures and basic operation. The actual application proves that the ADB69-type bag packaging machine fully meets the expected design goals and has a comparative advantage. Big promotion value.

A series of problems brought about by our factory's bottom loading and manual tonnage bag packaging, such as slow packaging speed, large loss of alumina flyover, poor packaging environment, inability to meet production and sales requirements, etc. Ton bag packaging machine has no delay. After the unremitting efforts of researchers, the ADB69-ton bag packaging machine was finally successfully developed.

1. DB69 type bag packaging machine performance, structure and working principle

1 Performance of ADB69-ton bag packaging machine Packaging capacity: 60 tons/hour Packaging measurement error: ±1%
Hoist motor power: 3kw
Compressed air consumption: 0.012m3/t-alumina (0.3~0.7Mpa)

2ADB69-ton bag packaging machine structure

The ton bag packaging machine is a mechatronic product. Mainly consists of electronic scales, double trailers and tracks, hoists, card holders, card packs, pneumatic card packers, pneumatic bag holders, fork-type blanking tubes, special pneumatic conical disc solid valves, pneumatic butterfly valves, and material accumulation Box and dust collection system, electronic control system and pneumatic circuit. The card holders are fixed on the electronic weighing trays, and the card wrapping rings, pneumatic card packaging machines and pneumatic bag holders are all fixed on the card holder. The blanking sleeves are inside the card wrapping rings, and the pneumatic butterfly valves and special The pneumatic conical disc solid valve is fixed on the fork-type feeding pipe, and the electronic weighing tray is provided with a track (the electronic upper track is not connected with the tracks on both sides), and the trailer is located on the track (electronic trailer can only accommodate one trailer) It can be reciprocated by the hoisting machine.

3ADB69-ton bag packaging machine works

After opening the fork-shaped card assembler and bag hanger, after the packaging bag is locked, the fine material feed butterfly valve and the thick blank conical disk solid valve are opened at the same time, and the material is dropped into the bag by gravity and the electronic weighing begins. (The calculated weight is the sum of the weights of materials, packaging bags, card holders, and electronic weighing trays). The air in the packaging bag is discharged from the gap between the card packing ring and the feeding tube to the dust collection system. When the net weight of the material reaches 990 kg, close the fine-cutting pneumatic butterfly valve and use the lower 40 mm hole in the butterfly plate to discharge the material. When the net weight of the material reaches 1000 kg, close the conical disc solid valve and loosen the fork-shaped card package. And trailers, mobile trailers, using two trailers to recycle packaging. Packed materials are transported by crane or forklift.

2. Improvement of ADB69 Tons Bag Packaging Machine

During the trial operation, the ton bag packaging machine basically reached the design goal, the packaging capacity reached 60 tons/hour, the packaging accuracy was 1000±1KG, and each system was operating normally. However, there are disadvantages of electronically weighed pits and easy to accumulate material and the two card pack cylinders are not synchronized to cause card holders to buckle. Therefore, the following improvements have been made:

1 Increase the dust collection pipe in the lower part of the electronic pit, which better solved the problem of material accumulation.
2 The conical carding device is changed to a fork-type carding device, and the fork-shaped carding device is a two-half-ring structure, which is respectively driven by two cylinders.

3. Its basic operation is as follows

Single-ton bag packaging machine packaging capacity: 60 tons - alumina / ton per ton of alumina packaging measurement error: ± 10 kg special pneumatic cone disk solid valve operation and sealing reliable bag holder simple and practical, better solution The problem of dumping caused by the fine grain size of aluminum oxide and the full filling of the bags.
The use of double-trailer moving cycle packaging improves packaging efficiency.
The PLC control is safe, convenient and reliable, and it can realize the automatic operation and control of card package, material discharge, metering, closing and discharging, loose packing and trailer moving.
It can realize the function of calculating the number of bags, and can carry out intelligent metering control according to the error of the weight of aluminum oxide in the static weighing.
The dust collection system works well and the packaging environment has been greatly improved.

4. in conclusion

The actual application shows that the ADB69-ton bag packaging machine fully meets the expected goals, it is simple and practical structure, small footprint, packaging and measurement once completed; successfully solved the impact of material impact on the measurement, measurement accuracy, packaging error small. The use of double trailer recycling packaging, high production efficiency. The combination of coarse and fine sizing can well solve the feeding control of large flow materials. The pneumatic mechanism is reliable in operation, and the special pneumatic cone disk solid valve operates reliably and seals, and the packaging environment is good. Of course, the device also has certain deficiencies. Because the packing machine relies on the buffering effect of the material accumulation box to make the material falling rate of the powdery material roughly uniform, the fluctuation of the material discharging speed caused by the change of the physical properties of the material needs to be summarized and improved in the future production and design.
