What should be paid attention to during the production of pla straw production line?The pla straw production line adopts a control system of PLC+temperature control module+touch screen, which greatly reduces the number of electric control devices of traditional discrete components, improves the reliability and operability of the equipment, and makes the whole equipment more concise! At the same time, it can meet the needs of digital management of the factory in the later stage, and all the key data of the production process can be uploaded to the central control room, so as to realize remote control and digital management! It is the trend and direction of the future development of the industry!
Compared with the traditional chemical raw material PP/PE, the modified biodegradable material PLA is more likely to absorb moisture in the air and become wet, resulting in changes in material properties. After the PLA material absorbs water and is heated in the barrel, water vapor bubbles will appear, which will affect the quality of the product! The pla straw extruder with drying device becomes inevitable! Therefore, the turnover, storage and use of PLA materials need to be effectively managed, which can reduce unnecessary losses!
The characteristics of the extrusion screw of the pla straw production line: 1) The separate spiral groove design of the BM structure is adopted to improve the plasticization effect of the material; 2) The pineapple nail (pin) screw is added to improve and enhance the uniformity of the mixing and plasticization of the raw materials; 3) Increase the length of the feeding section, the plasticizing section (also called the compression section) and the metering section (also called the homogenization section). The screw length-to-diameter ratio is 33:1, which extends the space distance of the heating movement of the material in the barrel.
The safety production of pla straw production line should pay attention to the following points:
1. The maintenance of the machine is carried out when the power is cut off and the machine is completely stopped to ensure safety. And regular maintenance and inspection; including power supply, lubrication, wear and other aspects of inspection;
2. When the machine is working, it is forbidden to put your fingers close to the moving parts. Machinery ensures that employees do not leave their posts during operation to avoid emergencies;
3. When the pla straw production line is working, it is forbidden to remove the protective cover. The machine can avoid unnecessary damage to the operation of the equipment by not drinking the straw;
4. The user's power supply should be equipped with an overvoltage protection device to ensure the safety of electricity use.
5. The equipment should be grounded reliably.
6. Strictly follow the prompts of the safety signs. The safety signs are kept clean and must not be covered or peeled off.
