What is glass machinery?

Glass machinery mainly refers to industrial machinery and equipment used in the process of glass production and processing.Glass machinery is mainly divided into two categories: glass cold treatment equipment and glass heat treatment equipment.Glass cold processing equipment mainly includes glass cleaning machine, glass edge grinder, Goode glass sanding machine, etc., for glass surface treatment;Glass heat treatment equipment mainly includes toughening furnace, hot bending furnace, etc., to deal with the internal structure of glass.

Types of glass machinery

Glass machinery mainly include the following categories: float glass production line, the method of production line, toughened furnace, homogeneous furnace, laminating line, hollow line, coating line, screen printing equipment, glass edge grinding machine, glass washing machine, fully automatic eidur gudjohnsen glass sand machine, polishing machine, slice machine, cutting machine, drilling machine, engraving machine, etc., is one of the most common glass washing machine, glass edge grinding machine.

1.Glass sander

Introduce and function: in daily life, we often can see the surface of a few glasses is coarse, dumb smooth, some still have beautiful decorative pattern, design, so the machine that deals with this kind of effect, we call glass to hit arenaceous machine (also have to call glass gush arenaceous machine, glass to hit arenaceous machine), call a method different, the function is much the same as minor difference.

Glass play sand machine working principle: the high-speed rotation of the roller blades to the tangent of the imported sand flow according to the speed of 18 meters/seconds beating out, hits the sand by the acceleration is slowly through the transparent glass on the surface, the sand to shatter glass surface into shape on the microscopic pits one by one, on the whole surface of the glass frosting effect came out, according to the sand material hardness variety different size and shape on the glass surface has different treatment effect

2.Glass edge grinder

Introduction and function: glass edge grinding machine is mainly suitable for the processing of furniture glass, architectural glass and process glass. It is one of the cold processing equipment that produces the earliest and USES the largest amount of glass in the deep processing equipment.It is mainly used for grinding and polishing the bottom edge and chamfering of plain glass.General manual, digital display control, PLC computer control and other configuration.

The main reasons of glass surface grinding scratches are the raw material quality, process operation and equipment condition.

3.Glass cleaning machine

Special equipment for cleaning and drying glass surface before mirror making, vacuum coating, tempering, hot bending, hollow lamination and other deep processing processes.Glass cleaning machine is mainly composed of transmission system, scrubbing, water washing, pure water washing, cold, hot air drying, electronic control system.According to the needs of users, medium and large size glass cleaning machine is also equipped with manual (pneumatic) glass tilting car and inspection light source system.

4.Glass borer

Glass drilling machine is specially used for glass drilling machine, mainly divides into: base, work station, drilling, such as motor, the hole diameter is large, stand overhanging space is big, can work for various size of glass drilling, bench height is low, easy to operate, the drill adopts pneumatic control, speed stability, is the ideal glass processing enterprise drilling machinery.

Notes:

· pay attention to safety when debugging and using. Do not touch moving parts or live parts when starting the machine

· tools and other items should not be placed on the conveyor guide and cover

· in case of emergency, press the "emergency stop" button or pull down the air switch;

· pay attention to the grinding condition at any time: the grinding wheel loss should be compensated by feeding in time.

· keep the cooling water in the water tank sufficient and clean at any time to avoid burning the grinding wheel and glass, and clean the grinding impurities in the inlet and outlet water pipes in time to keep the water passage clear

· before work, check whether all travel switches work normally and whether the control direction is correct; if not, stop the machine immediately for inspection, otherwise the machine will be fatally damaged

5.Toughened furnace

2. Glass tempering furnace is equipment for producing tempered glass by physical or chemical means, including both physical and chemical means.

By heating the plate glass and then quenching it, the surface of the cooled glass will form compressive stress and the inside of the glass will form tensile stress, so as to improve the strength of the glass and make the ordinary annealed glass become the equipment of tempered glass.Since this type of toughening does not change the chemical composition of the glass, it is called a physical type glass toughening equipment.If the heating mode of the equipment is divided according to its characteristics, the equipment can be divided into forced convection heating steel equipment and radiation heating steel equipment;If according to the structure and functional characteristics of the equipment, it can be divided into combined steel equipment, flat steel equipment, bending glass equipment, continuous steel equipment, two-way steel equipment, hanging furnace and so on.

Chemical toughening equipment is to improve the strength of glass by changing the chemical composition of the glass surface.Because this type of toughening changes the chemical composition of glass, it is called chemically toughened glass equipment.

Before 2014, most enterprises adopted physical methods.

6.Hot bending furnace

Hot bending glass from the shape classification, can be divided into a single bending, bending, composite bending three categories.

For single-curved building glass, hot bending of glass is relatively easy.But a lot of manufacturers often are in the curvilinear place that the product leaves straight line side roughly 150mm, cannot agree with mould very well, some exceeded standard requirement, cause installation difficulty.To solve this problem, first of all, the electric heating arrangement of the hot bending furnace should be reasonable to achieve local heating, and the placing direction of the products should be consistent with the electric heating wire direction.

Bending hot bending glass common aquarium glass and counter glass, bending glass the biggest technical difficulties is the straight line side bending, folding corner easy to appear mold mark and other defects.Therefore, curved glass is also very common, such as spherical glass, turning arched corridor, glass washbasin, etc., this kind of glass in the hot bending operation requires a very high technical level, the production of accurate mold, some need professional hot bending furnace can be completed.

Hot bending glass is a curved glass made by heating, bending and softening high quality glass to meet the high quality demand of modern architecture.Beautiful style, smooth lines.It breaks through the oneness of flat glass, more flexible and diverse in use.Suitable for doors, Windows, ceilings, curtain walls and other special requirements of different shapes.

In general, China's hot bending glass technology is still relatively backward, for some specific glass hot bending, often fail to meet user requirements.For example, large size, deep arc glass hot bending, low yield.From the mechanical point of view, in the process of hot bending glass, the force from both sides to the middle concentrated, when the size of the force exceeds the allowable stress of glass, glass plate burst.Therefore, when the glass hot bending, can add an auxiliary external support, can be very good to solve this problem.

Development of glass machinery

The development of China's glass machinery industry began in the early 1990s, and the migration of foreign (taiwan-funded) enterprises began to take root in China. With the geographical transfer of the world's processing plants and the rapid development of China's relevant industries, the glass machinery industry began to develop rapidly in China.The early glass machinery manufacturing enterprises were represented by shenzhen yiweigao industrial development co., LTD., but later they diverge and become several leading enterprises in shunde and shenzhen, guangdong province.In the later development, it gradually expanded into two large areas dominated by the pearl river delta and the Yangtze river delta.

Glass machinery status quo

At the beginning of the 20th century, there was a trend following the emergence of glass processing enterprises.Foshan, shenzhen, guangzhou, Shanghai, hangzhou, suzhou, zhangjiagang and other industrial areas have appeared.At present, more than 50% of China's glass cold processing equipment is manufactured in shunde, guangdong.

Until 2014, China's glass machinery development is highly dependent on the international market.

The fine glass processing industry will keep a rapid development trend in China.It is estimated that from 2011 to 2013, the annual growth rate of auto and building laminated safety glass in the Chinese market will be about 30%.This means that the glass machinery industry in China has great potential for development and endurance.

Architectural and automotive glass and glass products, as the base material, play an increasingly important role in the development of diversification, and bring opportunities and challenges for glass production and processing equipment.Flexible production process and multi-functional production equipment are the development trend of the world glass processing industry in 2014.They require glass processing equipment to be highly repeatable and accurate.Automotive and architectural glass has been committed to reducing the thickness of glass to meet the needs of the market, which puts forward higher requirements for glass deep processing technology.Many glass deep processing enterprises began to improve the efficiency of the production line, glass deep processing all aspects of the integration.This will become the future development trend of glass deep processing industry.
