Analysis of prospects of daily glass equipment industry

1. The transformation of the mechanism of the daily glass industry provides opportunities and challenges for the equipment industry. The maturity of the socialist market economy will inevitably promote the reorganization and transformation of all industries. The daily glass industry has also reshuffled in the process of deepening reforms by undergoing evolutionary changes. Some old companies restructured or even eliminated the game because of mechanisms and systems. According to the law of market development, some newly-born enterprises stand out in the wave of reforms, in order to fill the market space released by outgoers to maintain the balance in the market. In addition, from the perspective of national consumption, the per capita consumption level of daily glass products in China is less than 6 kg/year, which is far from developed countries, and there is still a large market space. In this situation, domestically produced equipment with a price/performance ratio superior to that of imported equipment will certainly be favored by users, and its development prospects are very broad. It should be said that this is the responsibility given us by the times, the opportunities and challenges that the reform has brought us, and the future of the equipment industry is bright. However, we should also see that the development of the daily-use glass industry is also being challenged by imported products and market demand, and it will continue to withstand the test of the market in quality and design. Of course, every step in the product quality, the variety of flowers and colors, will inevitably put forward new requirements for equipment. For example, the axial uniformity of multi-lobed glass presses, glass jars, and blown glassware glassware is still a problem. Although there are other technological factors here, the equipment factors cannot be ignored. Therefore, in meeting production requirements, the equipment industry still has a long way to go.

Second, the daily glass equipment industry is maturing. With the deepening of reform and opening up, the daily glass equipment industry has made great progress in terms of volume and quality. First of all, in strengthening its own technological transformation, the universal application of CAD and CAM has improved the product's design level and manufacturing precision, and advanced analytical instruments have been used to scientifically test materials to ensure the stability of material quality. In the upgrading of the mechatronics of the product, the industry's products have been accelerated to the world advanced level, narrowing the gap between domestic equipment and the international advanced level. For example, the servo motor drive of the feeder simplifies the mechanism. Achieve multi-droplet linear shearing; rowing machine adopts electronic timing to optimize the automatic control level of the bottle-making machine; our "August Five" period for which the press machine's aerodynamic change electric product update is now mature; supporting the host The energy-saving annealing furnace, the kiln cellar, the wrap-in type feeder, the hot and cold end spraying equipment, the printing machine, the automatic inspection line for bottles and cans, the thermoplastic packaging machine, etc., relate to the modern equipment in various fields of daily glass production, basically All of them have been made domestically, and the design level and manufacturing level of some equipment have reached the international advanced level. In addition, in the manufacture of glass molds, the smelting of mold materials such as heat-resistant alloy cast iron and heat-resistant alloy steel has been performed using advanced electric furnace smelting. Machining centers, CNC machine tools, EDM machines, and wire-cutting machine tools have become the main equipments for mold processing. The durability of molds and machining accuracy have been greatly improved and are basically in line with international advanced standards. Therefore, China's daily glass equipment industry has entered the fast track of rapid development. This is mainly due to China's reform and opening up policy.

Third, an analysis of the quality of daily-use glass products on the improvement of equipment performance requirements The invention and development of glass products molding equipment is a process that imitates the artificial molding process. The closer the mechanical forming process is to the artificial process, the more mature it becomes. We know that the viscosity of the glass frit in the glass forming process is from low to high, while the glass frit is isotropic (ie, a ball) when there is no external force in the blowing process, but our product shape It is often a round, oblate or rectangular bottle type, so that the air blowing volume from the initial shape to the molding is the key to adjusting the axial uniformity of the glass. Whether it is blow-blow method or pressure-blowing method, it is a constant in the process of air blowing, that is, a pressure (pressure) is blown to the end. This is why the product will appear thin at both ends and reach the axial wall. Thick uniform. Specifically, the blowing process should be a process of blowing (expanding) → stopping (stretching) → blowing (expanding) → stopping (stretching) → strong blowing (sufficient), just as pulling the tube to make the product reach the axis Uniform wall thickness. Whether blowing a bottle or blowing a cup has this problem. This problem is advanced in the advanced countries due to the emphasis on the study of basic theory in the equipment debugging process is more reasonable, so the same machine to make the product is not the same. And we often do not want to introduce software when we introduce device hardware. In this issue, both glass manufacturers and machine manufacturers must care about this issue. In the past, we did not invest enough in the study of the forming mechanism. Now that foreign products have entered China in large quantities, we must compare our products with foreign products to make up the gaps and make up for the deficiencies and catch up. At the same time, it will certainly put forward new requirements for the equipment industry.
The above is for the blow-molded products, and we always put forward the goal of blowing thick-walled products and suppressing thin-walled products. This means that it is not easy to blow thick-walled products with uniform wall thickness, and it is not easy to suppress thin-walled products. At present, the press drive system uses electrical transmissions and the punch presses most of the hydraulic systems. This makes the punch stay in the product for a long time, which is not conducive to the molding of thin-walled products. In addition, hydraulic pressure punches should not be used for materials with relatively short material properties. In this regard, flexible control should be based on product requirements. For high-speed thin-walled products, pneumatic punches should be used as well.
In short, we have a long way to go in the integration of equipment and technology. It should be said that the development of the glass industry is inseparable from the support of the equipment industry, and the development of the equipment industry also depends on the development of the glass industry. Both parties are co-existing and co-existing together to promote the prosperity and development of the industry.
