Plastic limit environmental protection era, paper straw are environmentally and popular
2021.09.20
In the "environmental protection campaign", every consumer and related industries are changing themselves.
In particular, many people found that the disposable plastic straws provided by milk tea shops, fast food restaurants and bakery cafes had disappeared on the first day of 2021.
It's time for paper straws
Equipment: paper straw production equipment
Paper straw productive process
★
Now introduce the paper straw production equipment of COTRUST control system
High speed paper straw machine integrates paper feeding, winding and cutting. CNC multi-knife cutting system enables to cut finished paper tubes online.
#Paper straw machine roll cutting control process#
Paper straw machine cutting is divided into analog state and automatic state.
# Simulation state#
Through the virtual axis to give a speed, servo axis to follow the virtual axis to do chase cutting, convenient customer debugging.
#Automatic state#
The paper tape pass the encoder, reads the encoder and gives the virtual axis speed after conversion. The virtual axis serves as the main axis, and the servo axis follows the virtual axis to make chase cutting.
Key points in control
Paper tape through the encoder, the obtained data need to eliminate the impact of pulse jitter, speed calculation is difficult.
The control system should take into account factors such as idler ratio and synchronous ratio that affect shearing.
Mathematical model: based on the width of paper tape and the inner diameter of cylinder, the extension speed of paper tape winding can be calculated.

COTRUST solution configuration of paper straw roll cutting equipment
The paper straw machine adopts COTRUST CTH300 series H32 control CPU and connects to 4 servos through EtherCAT bus, which can complete paper rolling, support chasing and cutting and fast cutting paper tube respectively.
Advantages of COTRUST control system solution
01
High cost effective
The control system of writing paper tube machine is controlled by CTH300 series PLC H32, which is exquisite, practical and cost-effective.
02
Quick and Stable
H32 uses EtherCAT bus to control servo motor cutting equipment,cutting fast and high precise.
03
Advanced Algorithms
According to the process requirements, the control system to achieve multiple models and advanced algorithms, easy to use.
04
Powerful motion control function
H32 supports electronic CAM, electronic gear, chasing function, perfect to meet the needs of paper straw machine.
05
Automatic control
Automatic cutting, automatic straw falling, automatic speed control and automatic response when cutting.
06
Multiple knives cutting -save time
Can be equipped with multi-knives cutting equipment, one time roll out finished products, avoid secondary cutting, save manual time.
07
Compatibility
The control system can not only be applied to the manufacture of paper straw, but also to the ball pen core, small flag pole, coffee blender, cotton yarn tube and other paper pipe factory.
