One of my customers ordered a batch of EVA low melting point bags. The bags are rolled into continuous rolls. Each bag has a pre-cut line. The customer requires that each bag has its own number. All bag numbers must be consecutive and the numbers are determined by It consists of a QR code and encoded text, so workers can scan the QR code and read numbers while working. For example, the order consists of two models, one for 20,000 pieces and the other for 40,000 pieces. Then the bag number is QM-A0000001-QMA0020000. The other model is QMA0020001-QMA0060000. At the beginning, we felt that it was difficult for the inkjet printer to cooperate with our machine because the production speed of the machine was too fast and the inkjet printer did not have time to print. Therefore, we chose a handheld inkjet printer for our customers. Because the handheld inkjet printer cannot be used on our machines, we can only send it to customers for inkjet printing while using it, which reduces the customer's work efficiency. Finally, we contacted the machine supplier and discussed a plan, which was to inkjet the bag when making the pre-cutting line. This requires that the motor speed of the inkjet printer must match the motor speed of our bag production machine. Including power supply voltage, signal voltage, bracket, etc., this machine needs to be grafted onto our machine. Finally we found the right manufacturer. Continuous coding can be achieved on bags. This machine QRcode+variable. Android machines can adjust the size of QR codes and print barcodes, and also add micro-adjustment, which makes it easy to adjust the gap between machines. The size of the printed QR code is 127-254mm. One ink cartridge can print about 20,000 times. Completely meets our requirements.
