1. High-efficiency cooling packaging film blow molding device technology
This patented technology developed by Fujian Nian Feng Plastic Co., Ltd. is undoubtedly a major breakthrough in the cooling process of blow molding machines.The device cleverly integrates the core components of the air cooler, cylinder, hollow tube, etc. to build a very innovative cooling structure.
The air cooler can be called the “power heart” of the entire cooling system. It uses a high-power and high-efficiency fan model with super wind output capacity.At the moment of blow molding, the temperature of the packaging film is extremely high. At this time, the air cooler is quickly activated, and a steady stream of low-temperature and strong cold air is blown out, as if putting a cool “cloak” on the hot packaging film, so that its temperature can quickly fall back.Compared with the traditional method of relying on natural heat dissipation or simple air cooling, the cooling rate has been greatly improved. The packaging film, which might have taken a few minutes to enter the next processing process, can now reach the ideal temperature in just a few tens of seconds, greatly compressing the production cycle.
The cylinder plays the role of a “master of precise control”.It has a built-in high-precision position sensor and an advanced electric control system, which can accurately control the displacement and attitude of the hollow tube with micron-level accuracy according to the size, shape and production process requirements of the packaging film.When the packaging film is released from the blow molding mold, the cylinder quickly drives the hollow tube to tightly fit its surface, ensuring that the cold wind can cover every inch of the film surface without omission.
The hollow tube itself is cleverly designed, and the wall of the tube is densely packed with pores arranged in a spiral shape. The pore size and spacing of these pores have been repeatedly simulated and optimized.When cold air passes through the hollow tube, it blows out evenly and softly from the pores, like countless pairs of gentle hands, gently stroking the packaging film, effectively avoiding the ills of local quench or uneven air cooling, so that the packaging film always maintains a uniform and consistent state during the cooling and shrinking process, greatly improving the flatness of the product, reducing folds, deformation and other quality defects, and the yield can be increased by 15%-20%.
2. Intelligent frequency conversion and energy-saving blow molding technology
With the rising energy costs and increasingly stringent environmental protection requirements, intelligent frequency conversion energy-saving blow molding technology has come into being.The core of this technology is to equip the blow molding machine with an intelligent frequency conversion control system, which is like an “energy-saving steward”, monitoring the energy consumption and operating status of all aspects of the blow molding machine in real time.
In the screw drive part of the extruder, the intelligent frequency conversion system dynamically adjusts the speed and torque of the motor according to the degree of plasticization of the raw material and the extrusion pressure requirements.When the raw materials are more viscous and the extrusion resistance is large, the system automatically increases the motor power to ensure that the screw delivers the raw materials stably and efficiently; when the raw materials have good fluidity and the production load is small, the motor switches to a low-power operating mode to avoid unprovoked waste of energy.After actual production verification, compared with the traditional constant-speed drive blow molding machine, the energy consumption can be reduced by 25%-30% after adopting intelligent frequency conversion technology.
Not only that, but in the blow molding stage, the technology also shows off its skills.Through real-time monitoring of parameters such as the wall thickness and blowing-to-expansion ratio of the billet, the intelligent frequency conversion system accurately regulates the blowing pressure and flow rate.For thin-walled products, the blowing pressure is moderately reduced to prevent the membrane bubble from breaking; for thick-walled and high-precision products, the blowing strength is increased to ensure the molding quality.This kind of intelligent and precise control not only guarantees the stability of product quality, but also further optimizes energy utilization efficiency.
3. Rapid customization technology of 3D printing molds
The mold manufacturing process of traditional blow molding machines is cumbersome and the cycle is long, making it difficult to meet the increasingly diversified and personalized needs of the market.The rapid customization technology of 3D printed molds has broken this stalemate and brought new vitality to the blow molding machine industry.
With the help of advanced additive manufacturing technology, designers only need to complete the three-dimensional model construction of the mold in the computer software, and then they can start the 3D printer with one click.The printer uses high-strength, high-temperature-resistant plastic or metal powder materials, which are stacked and sintered layer by layer according to a preset model. It only takes a few hours to a few days (depending on the complexity of the mold) to create a blow molding mold with exquisite structure and extremely high precision.
This technology has not only significantly shortened the mold manufacturing cycle, from the traditional weeks or even months to the current short-term delivery, but also provides a broad space for product innovation.According to the niche needs of customers and emerging market trends, enterprises can quickly customize various special-shaped and multi-functional blow molding molds, such as packaging container molds with special textures and internal structures, to help enterprises seize the opportunity in market segments and meet consumers' pursuit of personalized plastic products.
Fourth, high-speed rotating blow molding technology
High-speed rotary blow molding technology is committed to overcoming the problem of forming large-scale blow molding products.In the production of large-capacity containers such as large-scale water storage buckets and industrial plastic tanks, traditional blow molding methods often face the dilemma of uneven wall thickness and low molding efficiency.
This technology adds a high-speed rotating device to the blow molding machine, so that the mold containing the plastic billet rotates quickly around the axis during the blowing process.The rotation speed can reach hundreds of revolutions per minute, and the strong centrifugal force causes the plastic melt to be evenly distributed on the inner wall of the mold, which effectively solves the problems of excessive bottom wall thickness and uneven side walls caused by gravity of large-scale products.
At the same time, with the optimized heating and cooling system, the high-speed rotating blow molding technology realizes the seamless connection of the production process.During the rotation of the mold, the heating element accurately controls the temperature to ensure that the heating of the billet is consistent throughout the mold; after the mold is blown and formed, the cooling air duct is quickly opened, and the air flow generated by the rotation is used to accelerate the heat dissipation.As a result, the production efficiency of large-scale blow molding products has increased by 30%-40%, and the product quality has reached an unprecedented level, meeting the urgent needs of large-capacity, high-quality plastic containers in industries such as chemical industry, food and beverage.
With the continuous development and widespread application of cutting-edge technologies of these blow molding machines, the plastic processing industry will surely open a new chapter, with higher efficiency and better quality, to deliver a steady stream of plastic products to the global market, and promote the vigorous development of all walks of life.
