PET packaging belt production line adopts German production technology and develops and develops from the traditional process flow based on China's actual situation. This production line mainly consists of the following equipment: feeding device, crystal drying device, plastic extruder, and non-stop Network changing device, head mold, constant temperature cast sink, first traction machine, constant temperature and frequency variable speed stretching box, first stretching machine, second stretching machine, embossing machine, shaping box, second traction machine, Winder composition.
This series of PET packaging tape production equipment 100% bottle-recycling materials are directly produced, green and environmental protection, use of waste resources, reduce production costs by 30%; according to the PET molecular chain structure and specially designed drying tank system, dew point -50 degrees below, increase in crystallinity Viscous and dry evenly, the produced packing tape has high tensile strength, and it does not crack without cracking. It has shaped oven, eliminates prestress, does not bend, has good shaping, uniform width and straightness, and can be widely used in automatic balers; easy to operate, Easy maintenance, low labor and electricity costs.
PET packing belt production line
1, crystal drying device;
2. Constant temperature cast sink, mainly composed of stainless steel body, frame, and lifting device, can be moved up and down, easy to operate quickly, can quickly cool the material, make its temperature below the melting point to granulate structure, granular molecular structure is easily Stretch to get high quality products.
3, the use of specially designed screw, high yield, low resistance, the molecular structure of the material damage is small, the melt viscosity is reduced, the heater is heated with a resistance heater, the speed is fast, high efficiency, digital automatic temperature control can automatically control the temperature . The drive motor controls the speed, and the screw speed varies depending on the finished product.
4, the use of fast automatic tool changing network device, high efficiency, equipped with melt pressure sensor, alarm device, changing the network in a timely manner, less waste. The melt metering pump stabilizes the melt pressure, maintains stable pressure, maintains belt-stabilized, simple die replacement, and is equipped with four die sets to produce a 9-25mm strap with fine workmanship to assure stable embryos. The series PET packing belt production line has the following features:
1, the use of the environment: not afraid of moisture, corrosion resistance, acid and alkali resistance, water absorption and moisture absorption is small, do not reduce the strength after immersion, the use of operational safety and other advantages.
2, the elongation is small: no relaxation, greater strength, can maintain tension for a long time, thus ensuring the cargo has excellent impact resistance in long-distance transport.
3, strong temperature resistance: melting point of 260 degrees, 120 degrees below the use of deformation, do not fade, do not soften, between -50 °C -100 °C, to maintain a good stability.
4. High degree of automation: After the polyester granules are put into the equipment, the materials are heated and melted, extruded into belts, cooled, baked, stretched, printed, embossed, wound and other processes are synchronously controlled and automatically completed.
5, good economic benefits: PET plastic steel belt density is only 1/6 of the density of steel strip, the price per unit length is relatively low, 1 ton plastic strip length is equivalent to the length of 6 tons of steel strip, and the cost per meter is lower Steel strips.
