Automatic Weighing And Packaging Machine For Bag In Bag

  • This machine is mainly composed of main packaging machine, multi-head combination weigher, z-type material conveyor, support platform, and output conveyor (finished product conveyor).
  • This packaging machine is fully automatic, from putting the material into the Z-type loader, then lifting it to the multi-head scale, automatically weighing through the multi-head scale, reaching the target weight, filling it into the packaging machine and sealing the synthetic bag, and then conveying the finished product The machine outputs the packed bags.

Machine Component

1) Main packing machine, 2) multi head combination scale, 3) z-type material conveyors, 4) support platform,5)  output conveyor (the finished product conveyor).

Main packing machine :Fully complete the production process of feeding, metering, filling, bag making, date printing and product output.

 Multihead electronic scale :Multi-head electronic combination scale : High-precision sensors enable accurate metering for instant implementation.According to the characteristics of the object to be measured, the opening and closing speed of the hopper door can be finely adjusted to prevent breakage. All parts are made of stainless steel and are clean and hygienic.Good compatibility and easy to use with other packaging equipment.

 Z type material elevator  : The Z-type feeder can control the speed, which can raise the material to the multi-head combined electronic scale at a uniform speed, and is controlled by electric eye induction to ensure sufficient material.

Output conveyor :The finished product conveyor is installed at the product outlet of the main machine of the packaging machine, which allows the finished product to be transported away from the bottom of the main machine, avoiding product accumulation and blockage and causing downtime.

Machine Features

The characteristics of this machine is that it is mainly used for packing large bags with large gram weight, and it uses 5L weighing bucket to increase the weighing, so the packing speed is fast. The size of the machine is higher, so it needs a higher workshop.

The Z-type feeder vibrates and feeds the materials to the multi head combined electronic scale for automatic weighing, and then fills the materials with the target weight into the packaging machine, and then the finished product conveyor outputs the packed bags. It can realize automatic lifting, measuring, forming and sealing bags, date coding, and output a series of automatic packaging processes.


It is suitable for the quantitative weighing and packaging of puffed food such as potato chips, puffed food, large shell nuts such as walnuts, cashew,pistachios, candy, melon seeds, biscuits, fruit and vegetable chips, fried goods, jelly, plum, chocolate and other leisure food, quick-frozen dumplings, frozen food, pet food, hardware and other granular, block, strip materials.

First of all, we must know the material, bag size and weight, these things are very important to the packaging machine. The designer will provide a schematic diagram and a salesperson to provide a quotation plan based on the customer's material, weight and bag size. This is a bag-in-bag food packaging machine. Common questions from customers are as follows.

1. Regarding the size of the bag, what should the customer do if there is no bag size? The suggestion is to experiment with local markets and supermarkets to see which bag type and the weight you want to pack are the most popular. Only the width of the bag is fixed, because the length of the bag is adjustable. 2. What is the maximum bag size of this machine? The bag length of this machine is 100-500mm, and the maximum width is 180-350mm. 3. Is the more shapers the better, so that more bag sizes can be packed? A set of machines can produce up to 3 formers, because the technology of replacing the formers is complicated, and changing the formers multiple times will cause the bag to have deviations. 4. How to choose the material of the machine? Our machine has two materials, one is stainless steel and carbon steel. If you are pursuing high quality, choose stainless steel. If your financial budget is difficult, carbon steel is recommended. Although the appearance of the machine is carbon steel, the parts that come into contact with the material are made of stainless steel. 5. What is the error? Generally speaking, it is ±1% (depending on the characteristics of the material) 6. How many days does it take to produce a machine? The production time is about 30-45 days, because our machines are installed and debugged at the same time, so as to ensure high quality. 7. The customer also asked how long is the machine warranty period? We offer 12 months warranty,starts from the issue date of bill of loading and life time maintenance service. 8. Customers ask most how to install and operate the video? You can't worry about this at all. Our company needs to provide user manuals, installation videos and operation of the machine, you can provide technical services when you encounter problems.
