With the development of society, the automation of production lines has been updated and iterated. The dynamic online checkweigher was developed and produced under this background. The dynamic online checkweigher can double the speed of online product weight detection, while ensuring product quality problems to achieve quality assurance effect. The dynamic online checkweigher can accurately detect the unqualified products in the continuous production line, and perform the control of the upper and lower line discrimination or the automatic weight sorting according to this, the qualified ones will be returned to the original conveyor belt, and the unqualified products will be rejected (or Alarm and shutdown), and has the functions of classifying and counting products according to settings, automatically providing feedback signals to adjust and correct feeding equipment, text display failure alarm information, and multiple graphic statistical displays. Become the best quality inspection equipment for automatic production lines and packaging lines.


Sorting principle of dynamic online checkweigher

  1. The product enters the feeding conveyor, and the speed setting of the feeding conveyor is jointly determined according to the product spacing and the required speed. The purpose is to ensure that only one product can be weighed on the dynamic online checkweigher during the work process. 

  2. When the product enters the dynamic online checkweigher, the system can determine the time when the product leaves the weighing conveyor according to the external signal, the operating speed of the dynamic online checkweigher and the length of the conveyor. From the product entering the weighing platform to leaving the weighing platform, the load cell will detect the signal, and the controller selects the signal in the signal stable area for processing, and the weight of the product can be obtained;

  3. After the controller obtains the weight signal of the product, the system will compare it with the preset weight range, filter the product, and the rejection form will vary according to the actual boredom. Since Shanghai Shigan has been engaged in the manufacture of checkweighers for 10 years, it has explored five removal methods, which can be adapted to most materials. They are: Panel Tumover Type (suitable for medium hard packaging products). Air-sweeping Type(suitable for small packages below 800g), Dropped Type(Suitable for thin, not easy to slide, easy to damage items), Push Type (suitable for hard packaging. Plastic film must be installed with a rejection brush.) and Driving Lever Type( make the volume of eliminating part lengthened)


The use of dynamic online checkweigher must pay attention to details, and attention must be paid to details to make better use, so that the life of the dynamic online checkweigher can be extended.

  1. Check the dynamic online checkweigher before use. This is a basic operation for technicians to work. No matter what machine is used, check before starting work. Check that the machine is running normally, and check whether the circuit and the environment around the machine are Affect the work of the machine, so as to ensure the normal production of the machine.

  2. If you are contacting the new dynamic online checkweigher, you must remember to read the manual carefully before using it. Different dynamic online checkweighers will have different operating details.

  3. The machine needs to be cleaned up in time after use. After using the dynamic online checkweigher, we must clean up the foreign objects or residues on the weighing machine in time. This is to prevent foreign objects from entering the machine and causing damage. At the same time, we should also pay attention to it. Carry out cleaning, maintenance and maintenance of the machine.
