Advantages of Twin Head Blown Film Machine

A twin head blown film machine has two sets of extrusion systems, two sets of die heads, and one set of racks. Compared with a single-head blown film machine, its production capacity is greatly improved. For example, the output of different models of twin-head blown film machines can range from 170 kg/h to 320 kg/h, meeting the needs of large-scale production.

Taking the double-head blown film machine of Zhejiang Chaoxin Machinery Technology Co., Ltd. as an example, the output of LDPE is 200 - 320 Kg/h, and the output of HDPE is 170 - 240 Kg/h. These data fully demonstrate the advantages of the twin-head blown film machine in high-efficiency production, which can bring higher output for enterprises and meet the needs of large-scale production.

The barrel and screw are made of high-quality alloy steel through nitriding and precision machining, with the best hardness and corrosion resistance, improving energy utilization. The energy-saving of the twin-head blown film machine is mainly reflected in two aspects: the power part and the heating part. The power part usually adopts an inverter, which can save the excess energy consumption of the motor. For example, if the actual power of the motor is 50 Hz, only 30 Hz may be required to generate sufficient power during production, avoiding the waste of excess energy. The heating part is mostly realized by an electromagnetic heater, and the energy-saving rate is about 30% - 70% of that of the old resistance coil. The electromagnetic heater has the advantages of fast heating speed, reduced heat transfer loss, improved production efficiency, keeping the motor in a saturated state to reduce power loss, and an additional insulation layer to improve heat energy utilization.

The scientific design makes the operation more convenient. Although some people think that at least two or three people are required for operation, from the perspective of overall production efficiency, the twin-head blown film machine reduces labor costs. The design of two sets of extrusion and two sets of die heads increases the production volume. Under the same workload, the required manpower is relatively reduced. Moreover, its operation is relatively convenient, reducing the work intensity of operators and improving work efficiency.

Compared with multiple single-head blown film machines, the twin-head blown film machine occupies less floor space, saving production plant space. In a limited plant space, the twin-head blown film machine can utilize the space more efficiently, saving site costs for enterprises. At the same time, its compact design also facilitates the layout and management of the production line for enterprises.

The twin-head blown film machine can be used to produce plastic films such as LDPE and HDPE, with a wide range of application fields and strong adaptability.

It performs well in making various vest bags, flat bags, etc., and is widely used in the food packaging field to provide safe and reliable packaging for food and extend the shelf life of food. In clothing packaging, the plastic film produced by the twin-head blown film machine can protect clothes from dust, moisture, etc., and keep the clothes clean and beautiful. In the textile industry, it can be used to package textiles to prevent them from being damaged during transportation and storage. The industrial field has high requirements for packaging, and the twin-head blown film machine can produce plastic films that meet industrial standards and provide good protection for industrial products.

In short, with its wide application range and strong adaptability, the twin-head blown film machine has become an ideal choice for packaging in many industries.

The twin-head blown film machine performs excellently in technology and has many advanced features, ensuring the reliability of its quality.

The screw diameter and length-diameter ratio of the twin head blown film machine are scientifically designed and very reasonable. For example, the common screw diameters are 55mm, 60mm, 65mm, etc., and the length-diameter ratio is generally 1:28 - 30. Such a design makes the screw speed range wide and can adapt to the processing needs of different materials. Whether it is the processing of LDPE or HDPE plastic films, an appropriate speed can be found to ensure the high efficiency and stability of production.

The twin-head blown film machine can produce high-quality films. The single-sided thickness of the film can be adjusted between 0.006 - 0.10mm, and this wide adjustment range meets the requirements of different packaging needs for film thickness. At the same time, its maximum folding diameter can also be adjusted according to different specifications to meet the size requirements of various packaging. For example, the maximum folding diameter of some models of films can reach 550mm×2, 650mm×2, 750mm×2, etc., providing diverse choices for packaging in different industries.

The total power of the twin-head blown film machine matches the output, ensuring the stable operation of the equipment. Taking some common models as examples, the power of the main machine is 15Kw, 18.5Kw, 22Kw, etc., and the total power is between 26Kw - 35Kw according to different models. Such a power configuration will not cause energy waste and can meet the power demand of the equipment during the production process, ensuring the high efficiency and stability of production. At the same time, the moderate power also reduces the operation cost and maintenance difficulty of the equipment and improves the cost performance of the equipment.

The twin-head blown film machine performs well in innovative design and brings a convenient operation experience to users.

The rotating motor drives the lifting, which is convenient for better expanding the film body and avoids the problem of adhesion between the molds caused by the non-rapid cooling of the expanded film body.

The twin head blown film machine is equipped with a rotating motor, the output end of which is rotationally connected to the connecting plate, and the front surface of the connecting plate is fixedly connected to the rotating column. The bottom end of the fixed rope on the outer surface of the rotating column is connected to the first support plate. When the rotating motor works, it drives the rotating column to rotate, thereby retracting and releasing the fixed rope to realize the lifting of the first support plate. Such a design is convenient for lifting the film body, so that the film body can expand better. During the expansion of the film body, if it is not cooled quickly, it is easy to cause adhesion between the molds, and this lifting function can effectively avoid this problem and ensure that the film body remains in good condition during the expansion process.

The fixed column and the rotating barrel drive the mold body for fixation, avoiding the problem that the mold body cannot be stored when it is in an expanded state.

Two first fixed columns are jointly connected between the two fixing plates on the bottom surface of the first support plate, and a rotating barrel is clamped on the outer surface of each first fixed column. In the expanded state of the mold body, the first fixed column and the rotating barrel can play a role in fixing the mold body. Without such a fixing device, it would be difficult to store the mold body when it is in an expanded state.
