Hexin elliptical printing machine control scheme

Shi'en is unforgettable, so we have colorful thoughts and colorful years. Can we send a multi-color printing gift to the teacher?

What Xiaohe will talk about is this magical printing machine.

One picture to understand universal printing-screen printing

The ever-changing costumes, the heroes of multi-pictures and multi-colors:

Oval printing machine

The oval printing machine is suitable for all kinds of printing materials, glue, water slurry, ink, etc., and can achieve multi-color one-time completion. Compared with the circular turntable machine, the operation is more flexible, and the color register can be produced in two lines to increase the output.

Control points:

The 16-axis elliptical printing machine has 16 screen printing axes, and the two spindles need to be synchronized.

Traditional solution:

Single printing is used, and then the product is transported and printed again, which will cause inaccurate color registration and low efficiency.

Hexin program:

The Hexin solution uses the EthreCAT bus to control two spindle servo solutions, and each site exchanges data through a switch. The master station uses CTH200 series PLC H224 to communicate with the slave stations through MODBUS_TCP, and each slave station sends two pulses to control two screen printers. The interval scanning time between slave stations is more than 10Ms, which perfectly meets the scanning time.

Advantages of Hexin's solution:

1. H36 can be networked with 32 slave stations, with a large number of stations and high efficiency.

2. It can join the mobile 4G network and use MICO for remote control, no need to go to the HMI of the device to set it up.

3. Through the switch, HMI can be connected with each screen printing machine so that each station can be set on the touch screen.

4. The HMI interface adds a group setting function, which reduces the operation time of workers and is more convenient.

5. The spindle drive adopts speed mode control, which is divided into multiple speeds corresponding to multiple acceleration and deceleration times, so that the two main drive motors can achieve a better synchronization effect

6. The servo can be adjusted to the highest speed to run, improve the production efficiency of the whole machine, produce and print twice, and produce 500 pieces per hour, which exceeds customer requirements.
