Digital packaging machinery not only provides greater output and more flexible equipment, but also adds many new features such as: remote maintenance, integration with the company's ERP system, and evaluation of production data.
The era of automation in the packaging industry began approximately 20 years ago, when a fully programmable machine was equipped with a programmable logic controller PLC for controlling the logic functions and the mechanical power shaft of the drive. However, the flexibility of the first generation of automation equipment is not satisfactory, there are many types of food, the life cycle is shortened, and the products tend to be diversified, which stimulates greater demand for equipment flexibility. In later developed second-generation automation equipment, more and more functions were transferred from the mechanical power shaft to the electronic drive system, and the logic function was still controlled by the PLC system.
Control and drive technology has proven to be a key technology in the field of packaging machinery structures. Today's fully electronic third-generation machines have all the advantages of servo technology while setting new industry standards. Digital packaging machinery not only provides greater output and more flexible equipment, but also adds many new features such as: remote maintenance, integration with the company's ERP system, and evaluation of production data.
The logic functions originally performed by the PLC are losing their importance, and now the electronic motion function is dominant. With the increase in the flexibility of the equipment, the number of servo motors is also increasing. This means that physical and logical interfaces are no longer needed due to different programming languages ​​and systems. Since the mid-1990s, some companies have driven the trend of integrated motion control and logic control solutions in the area of ​​packaging machinery.
Top loading devices are becoming more and more popular in carton packaging. Flexible cartoners load from above and are more flexible than horizontal machines. The robot arm can be equipped with different vacuum grips to accommodate a wide range of products. This solution is also effective for composite packaging. For example, in pharmaceuticals, blister packs, ampoules, medicine bottles, medicine instructions, and medicine spoons can all be packaged using top loading equipment. In the confectionary area, top loading equipment is used to place a wide variety of different shapes of chocolate in deep dishes. The flexibility of top loading equipment operation is also valid for larger packaging. The machine needs only minor adjustments to adapt to different container shapes. This means that new product types can meet future requirements.
There are many kinds of pneumatic pipes, which are generally produced with PU raw materials, with stable quality, high pressure resistance, weather resistance, wear resistance, zigzag resistance, smooth and flexible pipe body, bright color, high elasticity, winding resistance and small bending radius.
The tube body is smooth and flexible, bright color, high elasticity, winding resistance and small bending radius. Temperature range: - 15 - + 70 ℃.
Product classification
1. Pu pneumatic pipe
2. Pu (polyether) pneumatic pipe
3. Pu (polyurethane) bobbin
4. Pu (polyether) bobbin
difference:
Polyurethane pneumatic pipe is over air type. If it is used for over water, its service life will be affected,
Polyether pneumatic pipe can pass air or water, with more stable physical properties and longer normal service life. It is an ideal material for pneumatic pipe.
The bobbin is wrapped with a layer of fiber in the middle of the common pneumatic pipe. Therefore, the bobbin is more solid, pressure resistant and non explosive than the common pneumatic pipe.
Product selection
What should be considered when choosing the type of plastics for blow molding pneumatic pipe?
The following aspects should be considered in the selection of pneumatic pipe materials.
Whether the wall thickness of the welded blank of the pneumatic pipe can be kept uniform, whether a higher blowing pressure is needed, whether the blowing is uniform, whether the surface of the pneumatic pipe is bright, whether the demoulding is easy, and whether the strength can meet the requirements, etc.
Performance comparison of plastics for blow molding pneumatic pipe. The pneumatic tube formed by blow molding is in thermoelastic state, and its density is smaller than that after cooling and shaping, resulting in shrinkage. For the general size of pneumatic pipe is not strict, forming shrinkage has little effect. But for the pneumatic pipes of specified size, such as some hoses used in precision machines, large shrinkage has a considerable impact. The larger the blowing volume is, the more significant the effect is.
The advantages of extruding and blowing plastic forming pneumatic pipe are less investment in production equipment, simple equipment structure, easy mold manufacturing, high forming of pneumatic pipe during production, uniform temperature control, and various specifications of pneumatic pipe can be formed. The disadvantage is that the wall thickness uniformity of pneumatic pipe is poor.
The advantages of injection blow molding pneumatic pipe are that the plastic pneumatic pipe has good product quality, accurate dimensions, no seams, uniform wall thickness, multi-mode molding production, high degree of automation, which is very suitable for large-scale high-efficiency production of small specifications. The disadvantage is that the investment of equipment and molding die is large, and the operation and production need skilled workers.

Tips for pneumatic pipe
Polyurethane pneumatic hose is suitable for compressed air, ordinary industrial water and non corrosive oil. In order to maintain a long service life, it must be used under rated working pressure and ambient temperature. As the temperature rises, the working pressure should be reduced accordingly. If it exceeds the limit, the hose may break. If the fluid temperature is too high or the fluid is corrosive, the hose may break. If the working environment temperature is too high or there is chemical gas in the working space, the hose may crack. If the hose is stored in a wet place or the storage period is too long, the hose may hydrolyze or age, which may lead to fracture
