Production method for automatically machining borosilicate glass series feeding bottles

Abstract

The invention relates to a production method for automatically machining borosilicate glass series feeding bottles. The production method includes steps of (1), precisely metering various raw materials according to composition requirements of borosilicate glass, and sequentially pouring the raw materials into a mixing machine to mix the raw materials; (2), melting the borosilicate glass, feeding raw glass materials into a fully-electric melting furnace at uniform and constant speed to realize high-temperature melting, and homogenizing bubble-free glass melt in a homogenizing layer after a clarification process; (3), supplying materials to regulate the temperature of the glass melt, regulating the temperature of the glass melt in a glass material supply pipeline so that temperature required for forming feeding bottles is achieved; (4), forming and manufacturing the feeding bottles; (5), realizing precision cutting for round openings of the feeding bottles; and (6), realizing annealing treatment for the feeding bottles. The production method has the advantages that the glass of the feeding bottles is fine in transparency, appearances of the feeding bottles are smooth and bright, mold joint close lines are avoided, and the feeding bottles can be cleaned and checked easily. In addition, the feeding bottles can be boiled and sterilized at high temperature and cooled instantly by cold water to be used without breakage, can also be heated in a microwave oven, are fine in chemical stability and cannot be reacted to water, and acid and alkali substances after being used for a long time.

Description

technical field [0001] The invention relates to the technical field of manufacturing feeding bottles and glassware for infants and young children, and mainly relates to a method for manufacturing feeding bottles of borosilicate glass automatic mechanism series. Background technique [0002] Most of the existing feeding bottles are plastic feeding bottles and glass feeding bottles; [0003] Plastic baby bottles are organic polymer materials that cannot withstand high temperatures for a long time, so the baby bottles are not suitable for steaming and high-temperature disinfection. The material itself is easy to age and release harmful substances after long-term use. Plasticizers (plasticizers) are added to the materials during manufacture. , Because the plasticizer contains phthalate plasticizer ingredients, its ingredients are similar to artificial hormones, which will harm male reproductive ability and promote female sexual precocity. Long-term large intake can lead to liver...

Problems solved by technology

Since young children are in the developmental stage of the endocrine system and reproductive system, the potential harm of DEHP to young children will be greater; in addition, the transparency of the feeding bottle is poor, which is not conducive to cleaning and observation

[0004] At present, there are soda-lime glass feeding bottles and borosilicate glass feeding bottles. Soda-lime glass feeding bottles have poor chemical stability. Long-term use will cause flakes, which will be absorbed by the human body into the blood to form thrombus. Calcium glass has poor resistance to rapid heat and rapid cooling. It cannot be sterilized by high-temperature cooking or used alternately with hot and cold water, and it is easy to burst; borosilicate glass baby bottles are currently made of borosilicate glass tubes for secondary processing. Temperature is the phase separation and crystallization point of the material, so the microscopic molecular structure arrangement of the glass material itself changes during processing, which changes the chemical and physical properties of the material itself and greatly reduces its performance, which is close to that of sodium calcium glass. Glass performance, the bottom of the baby bottle is made of glass tube secondary bottom sealing method, the thickness of the bottom of the baby bottle manufactured by this method is less than 0.5mm, the mechanical strength of the bottom of the bottle is poor, it is easy to burst during use, and the safety hazard is large. This method is all manual operation efficiency It is extremely low. In addition, glass tubes in the market are basically used at present. The quality of glass tubes is fake, which makes it difficult to guarantee the quality of baby bottles.
