The working principle of linear weighers

The linear weigher adopts the structure of gibbons, with reasonable structure, beautiful shape, smooth operation, energy-saving, convenient operation, and accurate weighing. The linear weigher is suitable for packing mineral powder, lime powder, talcum powder, urea, fertilizer, flour, fertilizer, inorganic salt, cement, rice bran, starch, and other powders. Here to understand the working principle of the linear weigher and other related issues!

Here is the content list:

Linear weigher basic working principle and structure.

1. When thelinear weigherenters into automatic operation, the control system opens the feeding door and starts to add material. The feeding device is fast and slow feeding; when the weight of the material reaches the fast feeding set value, stop fast feeding and keep slow feeding; when the weight of the material reaches the final set value, close the feeding door and complete the weighing process of the linear weigher.

2. At this time the system detects whether the bag clamping device is in the predetermined state when the bag has been clamped, the linear weigher system sends a control signal to open the weighing hopper discharge door, the material enters the bag after the material is released the weighing hopper discharge door is closed automatically.

3. After unloading the empty material, the linear weigher clamping device is released and the bags fall automatically; after the bags fall, they are sewn and transported to the next station. So on and so on automatic operation.

4、The key component affecting the packing speed and accuracy is the weighing unit of the linear weigher, which includes the storage bin, gate, cut-off device, scale body, bag clamping device, bracket, electrical control device, etc.

5. The storage bin is a buffer type bin for material storage and provides a near-uniform material flow; the gate is located at the bottom of the bin and is used to seal the material in the bin when thelinear weigher is overhauled or malfunctioning; the cut-off device consists of a cut-off hopper, a cut-off door, pneumatic components, a filler door, etc., which provides fast and slow feeding during the weighing process of the linear weigher, and the material flow of both fast and slow feeding can be individually. This ensures that the linear weigher meets the accuracy and speed requirements of the measurement.

6. The function of the complementary air door is to balance the air pressure difference in the linear weigher system during weighing; the weighing body is mainly composed of the weighing hopper, the load-bearing support, and the load cell, which completes the transformation from weight to electrical signal and transmits it to the control unit; the bag clamping device is mainly composed of the bag clamping mechanism, pneumatic components, etc. The function is to clamp the bag so that all the materials weighed by the linear weigher fall into the bag.

7. The electrical control unit consists of a weighing display controller, electrical components, and a control cabinet, whose role is to control the work of the system so that the whole linear weigher system works in an orderly manner according to a pre-set program.

Technical characteristics of the linear weigher.

1. The linear weigher replaces manual packaging, automating packaging for large enterprises, small and medium-sized enterprises, improving the production efficiency of all industries and significantly reducing costs.

2. The linear weigher can be used for a wide range of packaging, for liquids, sauces, powders, granules, and solids of various materials, simply by choosing different metering filling linear weighers according to the different materials.

3. In line with the unhygienic standards of food processing machinery, the parts on the linear weigher that come into contact with the material or the bag are processed in stainless steel or other materials that meet the requirements of food hygiene, ensuring the hygiene and safety of the food.

4. Low loss of packaging material, the linear weigher uses pre-made bags with a bag pattern and good sealing quality, thus improving the grade of the product.

5. Easy to operate, the PLC plus POD (touch screen) electrical control system used has a friendly human-machine interface and is easy to operate.

6. Linear weigher automatically completes bag making, line feeding, labeling, dosing, filling, sealing, slitting, and counting.

The computerized multiheaded weigher is the main product of our company; it is a high accuracy, fast speed, highly automatic, widely used in the ration packing of candy, sunflower seeds, popcorn, granulate and frozen foods.
